Replicube A game by Walaber Entertainment LLCDev snapshot: Godot 4.5 dev 5By: Thaddeus Crews2 June 2025Pre-releaseBrrr… Do you feel that? That’s the cold front of the feature freeze just around the corner. It’s not upon us just yet, but this is likely to be our final development snapshot of the 4.5 release cycle. As we enter the home stretch of new features, bugs are naturally going to follow suit, meaning bug reports and feedback will be especially important for a smooth beta timeframe.Jump to the Downloads section, and give it a spin right now, or continue reading to learn more about improvements in this release. You can also try the Web editor or the Android editor for this release. If you are interested in the latter, please request to join our testing group to get access to pre-release builds.The cover illustration is from Replicube, a programming puzzle game where you write code to recreate voxelized objects. It is developed by Walaber Entertainment LLC (Bluesky, Twitter). You can get the game on Steam.HighlightsIn case you missed them, see the 4.5 dev 1, 4.5 dev 2, 4.5 dev 3, and 4.5 dev 4 release notes for an overview of some key features which were already in those snapshots, and are therefore still available for testing in dev 5.Native visionOS supportNormally, our featured highlights in these development blogs come from long-time contributors. This makes sense of course, as it’s generally those users that have the familiarity necessary for major changes or additions that are commonly used for these highlights. That’s why it might surprise you to hear that visionOS support comes to us from Ricardo Sanchez-Saez, whose pull request GH-105628 is his very first contribution to the engine! It might not surprise you to hear that Ricardo is part of the visionOS engineering team at Apple, which certainly helps get his foot in the door, but that still makes visionOS the first officially-supported platform integration in about a decade.For those unfamiliar, visionOS is Apple’s XR environment. We’re no strangers to XR as a concept (see our recent XR blogpost highlighting the latest Godot XR Game Jam), but XR platforms are as distinct from one another as traditional platforms. visionOS users have expressed a strong interest in integrating with our ever-growing XR community, and now we can make that happen. See you all in the next XR Game Jam!GDScript: Abstract classesWhile the Godot Engine utilizes abstract classes—a class that cannot be directly instantiated—frequently, this was only ever supported internally. Thanks to the efforts of Aaron Franke, this paradigm is now available to GDScript users (GH-67777). Now if a user wants to introduce their own abstract class, they merely need to declare it via the new abstract keyword:abstract class_name MyAbstract extends Node The purpose of an abstract class is to create a baseline for other classes to derive from:class_name ExtendsMyAbstract extends MyAbstract Shader bakerFrom the technical gurus behind implementing ubershaders, Darío Samo and Pedro J. Estébanez bring us another miracle of rendering via GH-102552: shader baker exporting. This is an optional feature that can be enabled at export time to speed up shader compilation massively. This feature works with ubershaders automatically without any work from the user. Using shader baking is strongly recommended when targeting Apple devices or D3D12 since it makes the biggest difference there (over 20× decrease in load times in the TPS demo)!Before:After:However, it comes with tradeoffs:Export time will be much longer.Build size will be much larger since the baked shaders can take up a lot of space.We have removed several MoltenVK bug workarounds from the Forward+ shader, therefore we no longer guarantee support for the Forward+ renderer on Intel Macs. If you are targeting Intel Macs, you should use the Mobile or Compatibility renderers.Baking for Vulkan can be done from any device, but baking for D3D12 needs to be done from a Windows device and baking for Apple .metallib requires a Metal compiler (macOS with Xcode / Command Line Tools installed).Web: WebAssembly SIMD supportAs you might recall, Godot 4.0 initially released under the assumption that multi-threaded web support would become the standard, and only supported that format for web builds. This assumption unfortunately proved to be wishful thinking, and was reverted in 4.3 by allowing for single-threaded builds once more. However, this doesn’t mean that these single-threaded environments are inherently incapable of parallel processing; it just requires alternative implementations. One such implementation, SIMD, is a perfect candidate thanks to its support across all major browsers. To that end, web-wiz Adam Scott has taken to integrating this implementation for our web builds by default (GH-106319).Inline color pickersWhile it’s always been possible to see what kind of variable is assigned to an exported color in the inspector, some users have expressed a keen interest in allowing for this functionality within the script editor itself. This is because it would mean seeing what kind of color is represented by a variable without it needing to be exposed, as well as making it more intuitive at a glance as to what color a name or code corresponds to. Koliur Rahman has blessed us with this quality-of-life goodness, which adds an inline color picker GH-105724. Now no matter where the color is declared, users will be able to immediately and intuitively know what is actually represented in a non-intrusive manner.Rendering goodiesThe renderer got a fair amount of love this snapshot; not from any one PR, but rather a multitude of community members bringing some long-awaited features to light. Raymond DiDonato helped SMAA 1x make its transition from addon to fully-fledged engine feature (GH-102330). Capry brings bent normal maps to further enhance specular occlusion and indirect lighting (GH-89988). Our very own Clay John converted our Compatibility backend to use a fragment shader copy instead of a blit copy, working around common sample rate issues on mobile devices (GH-106267). More technical information on these rendering changes can be found in their associated PRs.SMAA comparison:OffOnBent normal map comparison:BeforeAfterAnd more!There are too many exciting changes to list them all here, but here’s a curated selection:Animation: Add alphabetical sorting to Animation Player (GH-103584).Animation: Add animation filtering to animation editor (GH-103130).Audio: Implement seek operation for Theora video files, improve multi-channel audio resampling (GH-102360).Core: Add --scene command line argument (GH-105302).Core: Overhaul resource duplication (GH-100673).Core: Use Grisu2 algorithm in String::num_scientific to fix serializing (GH-98750).Editor: Add “Quick Load” button to EditorResourcePicker (GH-104490).Editor: Add PROPERTY_HINT_INPUT_NAME for use with @export_custom to allow using input actions (GH-96611).Editor: Add named EditorScripts to the command palette (GH-99318).GUI: Add file sort to FileDialog (GH-105723).I18n: Add translation preview in editor (GH-96921).Import: Add Channel Remap settings to ResourceImporterTexture (GH-99676).Physics: Improve performance with non-monitoring areas when using Jolt Physics (GH-106490).Porting: Android: Add export option for custom theme attributes (GH-106724).Porting: Android: Add support for 16 KB page sizes, update to NDK r28b (GH-106358).Porting: Android: Remove the gradle_build/compress_native_libraries export option (GH-106359).Porting: Web: Use actual PThread pool size for get_default_thread_pool_size() (GH-104458).Porting: Windows/macOS/Linux: Use SSE 4.2 as a baseline when compiling Godot (GH-59595).Rendering: Add new StandardMaterial properties to allow users to control FPS-style objects (hands, weapons, tools close to the camera) (GH-93142).Rendering: FTI - Optimize SceneTree traversal (GH-106244).Changelog109 contributors submitted 252 fixes for this release.

A New Museum Dedicated to Frida Kahlo’s Early Years and Family Life Is Coming to Mexico City The Museo Casa Kahlo will be located beside the popular Museo Frida Kahlo. It will display letters, artworks and mementos that shed light on the Mexican artist’s childhood Frida Kahlo in 1944 Bettmann via Getty Images A new museum dedicated to the early life of the Mexican painter Frida Kahlo is opening in Mexico City. Located in the city’s historic Coyoacán district, the Museo Casa Kahlo will tell the Mexican painter’s story through letters, toys, artworks and other personal items. “This museum isn’t just about her work—it’s about her world,” Frida Hentschel Romeo, Kahlo’s great-grand-niece, tells Vogue’s Chloe Schama. “It’s about how the people closest to her shaped who she became. And it’s also about the living family—those of us who carry her legacy forward.” The museum will occupy a building known as Casa Roja, a home belonging to the Kahlo family. It’s next door to the already famous Casa Azul, the family home built by Kahlo’s father in 1904. The Museo Frida Kahlo, which occupies Casa Azul, has been open since 1958. Andrew Hasson / Getty Images Born in 1907, Kahlo grew up in Casa Azul and later shared it with her husband, fellow artist Diego Rivera. She purchased the neighboring red house (also owned by her parents) for her sister Cristina’s family. Four years after Kahlo’s death in 1954, Casa Azul was converted into the popular Museo Frida Kahlo, which displays art and objects from Kahlo’s adult life alongside rotating exhibitions. Casa Roja has remained in the Kahlo family, passed down by Cristina’s descendants. “Cristina was by her side through so much,” Hentschel Romeo tells Vogue. “Traveling with her to New York for her first major exhibition, supporting her through surgeries and recovery.” Frida Kahlo photographed by her father in 1932 Public domain via Wikimedia Commons Pain was a constant throughout Kahlo’s life. After sustaining serious injuries from a bus accident at 18, she endured chronic symptoms for the rest of her life. Despite these challenges, Kahlo thrived as an artist, garnering international acclaim for her vibrant, wrenching self-portraits. Some of Kahlo’s most famous paintings are painful depictions of women’s suffering, her own injuries and her turbulent marriage to Rivera, who had countless affairs (including one with Cristina). Casa Roja was eventually passed down to Cristina’s granddaughter, Mara Romeo Kahlo, who is Kahlo’s closest living relative, reports the New York Times’ Robin Pogrebin. Romeo Kahlo volunteered the red house to host the new Museo Casa Kahlo, which will open in late September. Its development is being overseen by Fundación Kahlo, a nonprofit recently established by the Kahlo family, which aims to “preserve Frida’s legacy and promote Mexican, Indigenous and Latin American art and culture on a global scale,” according to its website. “For the first time, the voice of the family will be at the heart of how Frida’s story is told,” Hentschel Romeo tells Vogue. As Romeo Kahlo explains to the Times, “The family was very important for Frida because it was her support.” While Casa Azul focuses on Kahlo’s adult life, the new museum will focus on her early development. Visitors will examine never-before-seen personal artifacts, such as childhood photographs, dolls, letters, jewelry, clothes and a piece of embroidery Kahlo sewed when she was 5. Other highlights include the artist’s only known mural and her first oil painting.Hentschel Romeo tells Vogue that Kahlo showed this painting to her husband, asking him to judge whether she had the talent to be a painter. “It is incredibly moving to see up close,” she adds. “This is a dream long held by our family,” Romeo Kahlo says in a statement. “Frida’s legacy belongs to the world, but it begins here—on this land, in these homes and in the culture that shaped her. Museo Casa Kahlo will allow us to tell new stories, share family secrets, host new voices and build a future that honors her spirit.” Get the latest stories in your inbox every weekday.

Facing huge fines, Apple on Monday began a legal challenge to the European Commission’s “unreasonable” demand that it open up its platforms to rivals, arguing any such move threatens the foundations of its platforms with a costly process that also undercuts its ability to serve customers. The company is, in a word, furious. It argued that it has cooperated with the Commission’s demands under the Digital Markets Act (DMA) and points to the investments it has already made in complying with that act. What Apple said “At Apple, we design our technology to work seamlessly together, so it can deliver the unique experience our users love and expect from our products,” the company said in a statement. “The EU’s interoperability requirements threaten that foundation, while creating a process that is unreasonable, costly, and stifles innovation. These requirements will also hand data-hungry companies’ sensitive information, which poses massive privacy and security risks to our EU users.” The company also noted that there is a real risk that people’s most sensitive information could be accessed, partially because it becomes so much harder to defend. These attempts are already taking place, Apple said. “Companies have already requested our users’ most sensitive data — from the content of their notifications to a full history of every stored Wi-Fi network on their device — giving them the ability to access personal information that even Apple doesn’t see. In the end, these deeply flawed rules that only target Apple — and no other company will severely limit our ability to deliver innovative products and features to Europe, leading to an inferior user experience for our European customers. We are appealing these decisions on their behalf, and in order to preserve the high-quality experience our European customers expect.” A one-sided approach What seems to really upset Apple is that some aspects of the demands mean the company will effectively be forced to hand its innovations out to businesses with which it is in direct competition — at no charge. That means Apple does not get to draw the full benefits of its work and makes it far more difficult to introduce products in Europe. What makes matters worse is that while Apple is being forced to open up in ways that advantage competitors, quite literally at its expense, it is not being given the opportunity to do the same back. Apple is the only company that these demands have been made of, meaning it is being forced to give its intellectual property away to others who do not need to play by the same rules. Some data hungry companies are already attempting to exploit the DMA to gain unfettered access to sensitive customer data. All the while, Apple is left alone and isolated in its quest to ensure user privacy consistent with GDPR regulation. It’s attempts to protect privacy are about protecting customers. Compliance? We are compliant While critics will continue to sneer and jeer at the company in their quest to rid the world of the “Apple Tax” only the world’s largest developers actually pay, Apple would argue that it has been making serious efforts to comply with the DMA. The company has opened up a portal developers can use to request additional interoperability with hardware and software features inside iPhones and iPads. Apple consistently opens up API access to iPhone, including opening up SMS messaging to RCS, HomeKit features and messaging services support. It has also put in place numerous other enhancements in response to the DMA, and while the warning messages it places when using third-party stores may be stark, this makes them no less true. Europe seems to want customers to use third-party stores with no warning at all that this is what is going on, which seems weird. Malicious regulatory compliance There is a degree to which much of the situation seems to reflect political, rather than economic or moral pressures. The fact that Europe is using Apple as a high profile example, while also refusing to be totally transparent about what it wants before levying any fines, suggests that the Commission is not so much deciding on facts as implementing a political decision using a set of laws that seem designed almost solely to punish one company. That’s the kind of malicious regulatory compliance Apple is furious about — a compliance regime that will now be tested in the courts. Will it make a difference?  Who knows? But the existential battle will decide the future of technology in Europe, and if the market is worth doing business in when compared to the cost of doing so. It will also determine the future of Apple, which will use its considerable resources to find some way to change the nature of the game. One group it seems unlikely to help will be those of Apple’s European customers who are happy and accustomed to the Apple ecosystem, and don’t particularly want to use third-party services, as Apple’s right to offer that “pure Apple” experience seems a likely sacrifice to Europe’s politically-driven zeal. That is, unless cooler heads do curtail the Commission’s attacks. You can follow me on social media! Join me on BlueSky,  LinkedIn, and Mastodon.

Text description provided by the architects. An ideal rural scenario, well-oriented and connected, tries to outline the premises of a seasonal residence. I first had contact with O&A online, having been recommended by a good acquaintance from London, the clients being in the central area of ​​Europe, I in Bucharest, and the construction site in Arges. The kind of equation that always attracts me, if the intentions are aligned. The situation at that time had the wreckage of a first failed attempt, already erected on the ground, and a small annex at the bottom of the lot, at the highest point of the area. The decision was for a full project, but with a phased implementation. So we started with the small body, in order to have better control and a final evaluation of our collaboration, but also of the executors. Being a more rural area, the expectations regarding the quality of the result had to be proportionate from the start. The annex was a construction with a small footprint, maximum 25 sqm, built in the past by the family, with vaulted walls bordered by a wooden structure at the top that served as a lantern. During the dismantling stage, we discovered that it had no pillars at the corners (or in general), and the concrete slab with a large belly in the middle. In the end, only the walls remained, which were reinforced with interior-exterior mesh.Save this picture!Save this picture!Save this picture!Save this picture!Leaving aside the condition of the construction and the poor materials, the position and proportion of the annex were harmonious, and the intention was to preserve these aspects from the start. The solution proposed an extension with an interior staircase area and a reconfiguration of the gaps/orientations from the inside to the outside. Structurally, the base remains intact, reinforced, and the superstructure is timber-framed. Finally, the exterior finish in black autoclaved wood completes and reveals the proposed scenario. The height and dimensions slightly exceed the initial image. The choice of exterior color is a direct response to the context, offering different images and visual relationships depending on the season. The entrance porch mediates the relationship between the module and the exterior through a fine metal structure, proportionate to the tall surrounding vegetation. The slats and semi-circular areas spatially define the moments of approaching the house. In the same tone, the rest of the functional areas inside are supported by their own connections to the exterior. The veranda pergola transforms into a deep balcony for the living area, and the foundation of the house articulates into a small terrace for the night area.Save this picture!Functionally, downstairs is the entrance with the night area, and upstairs the entire living area with kitchen, dining, living room, and a small bathroom. Along the same lines, downstairs we have smaller gaps, and there is a panoramic orientation of some windows of considerable size, which offers a cinematic sensation in direct relation to the exterior. The house being well-positioned among the trees, any movement and change of nature can be watched, studied, and heard. Continuing the space-function relationship, the ground floor offers regular, intimate spaces, while the staircase opens the living area with a generous space and a gabled ceiling. The context being the main "reason", the finishes are clean, neutral, to further strengthen this relationship. In the living area, the furniture pieces define the micro-functions necessary for living, and are combined in a balanced way through proportion, color, and materiality.Save this picture!Save this picture!Save this picture!By reconverting the annex and using natural materials, local teams, off-site construction methods, we tried, in the true and local sense of the expression – minimal impact on the environment and sustainable architecture.

Version 1.0.0 By Robert Jan van Pelt (Park Books, 2025) The largest artifact in the touring exhibition Auschwitz. Not Long Ago. Not Far Away., currently on display at the ROM in Toronto, is a wooden barracks building. It’s from the Auschwitz-Monowitz camp, a satellite to Auschwitz created to provide slave labour to the IG Farben corporation for the construction of a synthetic rubber factory.  The discovery of a sister building, back in 2012, led exhibition chief curator and architectural historian Robert Jan van Pelt, University Professor at the Waterloo School of Architecture, on a research journey to write a comprehensive history of the barracks—temporary buildings that have not only housed prisoners, but also provided shelter for military servicemen and women, refugees, and natural disaster survivors. “Many people have experienced, for shorter or longer time periods, life in a barrack, and for all of them it represented life on the edge, for better or worse,” writes Van Pelt. Worm’s eye axonometric of Renkioi Hospital Barrack, a prefabricated hospital designed by Ismabard Kingdom Brunel for a site in Turkey, 1857. Van Pelt’s book criss-crosses with ease through architectural history, military history, and the history of medicine—all of which played crucial roles in the evolving development of this seemingly simple building type. The book is arranged in a dozen episodes, with the barrack at the centre of each, serving as an anchor point for unfolding the rich intellectual and historical context shaping the way these structures were developed and deployed. The book is richly illustrated with archival materials—a feat in itself, given that the documentation for temporary buildings, particularly before 1900, is scarce. These drawings, photos, and paintings are supplemented with 20 worm’s eye views of key buildings, carefully composed by a team of Waterloo architecture school students and alumni.  Thomas Thomaszoon, View of the headquarters of the Spanish in the Huis tea Kleef during the siege of Haarlem, 1572-73. Collection of Noord-Hollands Archief, Haarlem; courtesy Robert Jan van Pelt Like many vernacular buildings, temporary structures larger than a tent, designed to house soldiers in the field, have existed at least since Ancient Rome. One of the first visual accounts of barracks came centuries later, in the winter of 1572, when the Spanish laid siege to the Dutch city of Haarlem, and cartographer Thomas Thomaszoon sketched the position of dozens of Spain’s wood-and-straw structures outside the city. The siege was successful, but only a few years later, the Dutch Republic gained the upper hand. As part of the creation of a standing army, they began to develop more precise instructions for the layout of camps, including the construction of temporary barracks. Antoine-François Omet des Foucaux, Barrack constructed in Hendaye, France, 1793. From Jean-Charles Krafft, Plans, coupes et élévations de diverses productions de l’art de la charpente, 1805. Collection of Bilbliothèque Nationale de France, Paris. Courtesy Robert Jan van Pelt The Napoleonic army made use of barracks in both military camps and training camps; by the mid-1800s, the construction of various barrack types was detailed in field construction manuals issued to officers in many European armies. During the Crimean War (1853-56), over 3,500 prefabricated barracks were manufactured in a Gloucester factory, as a solution to the appalling conditions at the front. But when the structures arrived at port, British forces were not able to unload and erect them—the materials for a single building weighed more than two tons, and each would require 60 horses (or 150 men) to transport to camp on the muddy roads.  The US (Union) Army’s Lincoln Hospital, Washington, DC, 1865. Collection of Library of Congress, Washington, DC. Courtesy Robert Jan van Pelt Prefabrication was also used, with somewhat more success, towards the end of the conflict to erect field hospitals designed by British engineer Isambard Kingdom Brunel with a priority on cross-ventilation to limit the spread of disease. Low mortality rates from similar structures led to a continued preference for “barrack hospitals” based on groupings of low-slung, well-ventilated pavilions, rather than conceived as single grand structures. The model was further refined with the addition of primitive underfloor heating and ridge ventilation by former surgeon William A. Hammond for the Union Army during the American Civil War (1861-65).  Barrack hospitals were constructed for civilian use, as well. Following the conclusion of the Franco-Prussian war (1870-71), such designs were built to house patients with infectious diseases in Berlin and proposed as a means to bring professional medical care to Germany’s rural areas. A barracks-inspired hospital was built in Saint Petersburg, Russia, in 1889, and continues to be operational.  If the barrack as an accommodation for the sick is a progressive tale, the 19th-century history of the barrack is equally checkered by the building type’s use for prisoner accommodation, including in the penal colonies of Australia and French Guiana. In North America, barracks were used in an internment camp for Native American Dakotas, and Civil War-era Union barracks at Camp Douglas were used to house Confederate prisoners. The oldest preserved barrack in the world may be in Canada, at Grosse Isle national park. Here, barrack-style quarantine sheds were used to detain thousands of Irish immigrant families during the typhoid fever epidemic of 1846-47, and their damp, fetid conditions contributed to many deaths—an episode Van Pelt describes as a “blot on the national consciousness of Canada.” A single Doecker Hut contains an operation room, pharmacy and hospital management office. The prefabricated, portable hospitals were developed in 1885, and used around the world, including in the First World War. In America, they were marketed for managing epidemics in the wake of the 1892 typhus fever outbreak in New York. Courtesy Berlin State Library and Robert Jan van Pelt   At the turn of the 19th century, the prefabricated portable barrack came to the fore with the manufacturing of the Doecker barracks, by Christoph & Unmack, a firm based in Copenhagen and Germany. Developed by a former military officer-turned-tentmaker, the technically sophisticated model used large rectangular frames that could be clipped together, and covered with “felt-cardboard”—dense felt pressed onto canvas and impregnated with linseed oil. The self-supporting structures proved easy to set up, dismount, and transport, making them suitable for both military applications—and, with little modification, for humanitarian aid. The Red Cross deployed Doecker barracks for use as field hospitals in Manchuria and Yokohama during the Russo-Japanese War (1904-05).  The Barrack, 1572-1914 wraps up in in the early 20th century, but with the note that in the ensuing decades until 1945, millions of barracks were produced by many of the world’s major nations—and that most of these were erected in barbed-wire-ringed compounds. “This is the period in which tens if not hundreds of millions of people, many of whom were civilians, were forced to live in barracks, as refugees, as expellees, as civilian internees, as forced laborers, as prisoners or war, as concentration camp prisoners, and as people made homeless by the destruction wrought by war,” writes Van Pelt. Up until 1914, he notes, this building type largely carried a sense of achievement—an image that would change sharply with the Age of the Camps. But although a WWII barrack was responsible for instigating Van Pelt’s initial investigation, that time period will need to await a second volume on this simple building type with a rich, complex, and complicated history.   As appeared in the June 2025 issue of Canadian Architect magazine  The post Book Review: The Barrack, 1572-1914—Chapters in the History of Emergency Architecture appeared first on Canadian Architect.

ExpressVPN is good at its job. It's easy to be skeptical of any service with a knack for self-promotion, but don't let ExpressVPN's hype distract you from the fact that it keeps its front-page promise of "just working." Outside of solid security, the two best things ExpressVPN offers are fast speeds and a simple interface. Our tests showed only a 7% average drop in download speed and a 2% loss of upload speed, worldwide. And while the lack of extra features may frustrate experienced users, it makes for a true set-and-forget VPN on any platform. This isn't to say ExpressVPN is without flaws — it's nearly bereft of customization options and it's notably more expensive than its competition — but it beats most VPNs in a head-to-head matchup. For this review, we followed our rigorous 10-step VPN testing process, exploring ExpressVPN's security, privacy, speed, interfaces and more. Whether you read straight through or skip to the sections that are most important for you, you should come away with all the information you need to decide whether to subscribe.

The first step for any setup process is to make an account on expressvpn.com and buy a subscription. Windows Once subscribed, download the Windows VPN from either expressvpn.com or the Microsoft Store, then open the .exe file. Click "Yes" to let it make changes, wait for the install, then let your computer reboot. Including the reboot, the whole process takes 5-10 minutes, most of it idle. To finish, you'll need your activation code, which you can find by going to expressvpn.com and clicking "Setup" in the top-right corner. You can install ExpressVPN's Windows app from the Microsoft store, but we found the website more convenient. Sam Chapman for Engadget Extreme simplicity is the watchword for all ExpressVPN's designs. The Windows client's launch panel consists of three buttons and less than ten words. You can change your location or let the app pick a location for you — the "Smart Location" is the server with the best combination of being nearby and unburdened. Everything else is crammed into the hamburger menu at the top left. Here, in seven tabs, you'll find the Network Lock kill switch, the four types of content blockers, the split tunneling menu and the option to change your VPN protocol. You can also add shortcuts to various websites, useful if you regularly use your VPN for the same online destinations. To sum up, there's almost nothing here to get in the way: no delays, no snags, no nested menus to get lost in. It may be the world's most ignorable VPN client. That's not a bad thing at all. Mac ExpressVPN's app for macOS is almost identical in design to its Windows app. The process for downloading and setting it up is nearly the same too. As on Windows, it can be downloaded from the App Store or sideloaded directly from the expressvpn.com download center. Only a few features are missing and a couple others have been added. Split tunneling is gone (unless you're still on a macOS lower than 11), and you won't see the Lightway Turbo setting. ExpressVPN recommends some servers, but it's easy to search the whole list. Sam Chapman for Engadget Mac users do gain access to the IKEv2 protocol, along with the option to turn off automatic IPv6 blocking — Windows users have to leave it blocked at all times. Almost every website is still accessible via IPv4, but it's useful if you do need to access a specific IPv6 address while the VPN is active. Android Android users can download ExpressVPN through the Google Play Store. Open the app, sign in and you're ready to go. The Android app has a very nice dark-colored design, only slightly marred by an unnecessary information box about how long you've used the VPN this week. ExpressVPN's Android app puts a little more information on the screen than it needs to, but still runs well. Sam Chapman for Engadget There's a large button for connecting. Clicking on the server name takes you to a list of locations. On this list, you can either search or scroll and can choose individual locations within a country that has more than one. We connected to as many far-flung server locations as we could, but not a single one took longer than a few seconds. The options menu is organized sensibly, with no option located more than two clicks deep. You will see a couple of options here that aren't available on desktop, the best of which is the ability to automatically connect to your last-used ExpressVPN server whenever your phone connects to a non-trusted wifi network. There are also a few general security tools: an IP address checker, DNS and WebRTC leak testers and a password generator. These are also available on the website, but here, they're built into the app. With the exception of the latter, we'd recommend using third-party testing tools instead — even a VPN with integrity has an incentive to make its own app look like it's working. iPhone and iPad You can only install ExpressVPN's iOS app through the app store. During setup, you may need to enter your password to allow your phone to use VPN configurations. Otherwise, there are no major differences from the Android process. ExpressVPN looks good on iPhone and iPad. Sam Chapman for Engadget The interface is not quite as pleasing as the dark-mode Android app, but it makes up for that by cutting out some of the clutter. The tabs and features are similar, though split tunneling and shortcuts are absent. Also, both mobile apps make customer support a lot more accessible than their desktop counterparts — plus, mobile is the only way to send email support tickets. Browser extension ExpressVPN also includes browser extensions for Firefox and Chrome. These let you connect, disconnect and change server locations without leaving your browser window. It's nice, but not essential unless you have a very specific web browser flow you like. ExpressVPN speed test: Very fast averages Connecting to a VPN almost always decreases your speed, but the best VPNs mitigate the drop as much as possible. We used Ookla's speed testing app to see how much of your internet speed ExpressVPN preserves. For this test, we emphasized the locations ExpressVPN uses for most of its virtual servers, including the Netherlands, Brazil, Germany and Singapore. Some terms before we start: Latency, measured in milliseconds (ms), is the time it takes one data packet to travel between your device and a web server through the VPN. Latency increases with distance. It's most important for real-time tasks like video chatting and online gaming. Download speed, measured in megabits per second (Mbps), is the amount of information that can download onto your device at one time — such as when loading a web page or streaming a video. Upload speed, also measured in Mbps, is the amount of information your device can send to the web at once. It's most important for torrenting, since the amount of data you can seed determines how fast you can download in exchange. The table below shows our results. We conducted this on Windows, using the automatic protocol setting with the Lightway Turbo feature active — a recent ExpressVPN addition that keeps speed more consistent by processing connections in parallel. Server location Latency (ms) Increase factor Download speed (Mbps) Percentage dropoff Upload speed (Mbps) Percentage dropoff Portland, Oregon, USA (unprotected) 18 -- 58.77 -- 5.70 -- Seattle, Washington, USA (best server) 26 1.4x 54.86 6.7% 5.52 3.2% New York, NY, USA 156 8.7x 57.25 2.6% 5.57 2.3% Amsterdam, Netherlands 306 17x 53.83 8.4% 5.58 2.1% São Paulo, Brazil 371 20.6x 53.82 8.4% 5.65 0.9% Frankfurt, Germany 404 22.4x 55.71 5.2% 5.67 0.5% Singapore, Singapore 381 21.2x 52.76 10.2% 5.64 1.0% Average 274 15.2x 54.71 6.9% 5.61 1.6% These are extremely good results. ExpressVPN is a winner on both download and upload speed. No matter where we went in the world, we never lost more than about 7% of our download speeds, and upload lost an astoundingly low average of 2%. This suggests that ExpressVPN deftly distributes its user load between servers to eliminate bottlenecks. This Ookla speedtest shows you can still get fast internet while connected to ExpressVPN -- our unprotected speeds are around 58 Mbps. Sam Chapman for Engadget The latency numbers look worse, but the rise in the table is less sharp than we projected. Ping length depends far more on distance than download speed does, so we expect it to shoot up on servers more than 1,000 miles from our location. Keeping the average below 300 ms, as ExpressVPN does here, is a strong showing. ExpressVPN security test: Checking for leaks A VPN's core mission is to hide your IP address and make you untraceable online. Our task in this section is to figure out if ExpressVPN can carry out this mission every time you connect. While we can't be 100% certain, the tests we'll run through below have led us to believe that ExpressVPN is currently leak-proof. Available VPN protocols A VPN protocol is like a common language that a VPN server can use to mediate between your devices and the web servers you visit. If a VPN uses outdated or insecure protocols, or relies on unique protocols with no visible specs or source code, that's a bad sign. Not all protocols are available on all apps, but Mac has the full range. Sam Chapman for Engadget ExpressVPN gives you a selection of three protocols: IKEv2, OpenVPN and Lightway. The first two are solid choices that support the latest encryption algorithms. OpenVPN has been fully open-source for years and is the best choice if privacy is your goal. While IKEv2 started life as a closed project by Microsoft and Cisco, ExpressVPN uses an open-source reverse-engineering, which is both better for privacy and quite fast. Lightway is the odd one out, a protocol you'll only find on ExpressVPN, though its source code is available on Github. It's similar to WireGuard, in that both reach for faster speeds and lower processing demands by keeping their codebases slim. However, Lightway was recently rewritten in Rust to better protect the keys stored in its memory. Ultimately, you can't go wrong with any of ExpressVPN's protocol options. 99% of the time, your best choice will be to set the controls to Automatic and let the VPN decide which runs best. Testing for leaks ExpressVPN is one of the best services, but it's not leak-proof (as you can read in the Background Check below). Luckily, checking for DNS leaks is a simple matter of checking your IP address before and after connecting to a VPN server. If the new address matches the VPN server, you're good; if not, your VPN is leaking. First, we checked the Windows app with split tunneling active to ensure the flaw really had been patched. We tested several servers and didn't find any leaks, which suggests the patch worked, though leaks were rare even before ExpressVPN fixed the vulnerability. We checked our IP while connected to the virtual India location, which is run from a physical server in Singapore. Don't worry -- it still looks like India to streaming services. Sam Chapman for Engadget In fact, we didn't find any leaks on any ExpressVPN server we tested on any platform. Though questions remain about iOS, as you'll see later in this section, that's a problem on Apple's end that even the best VPNs can do very little about for now. The most common cause of VPN leaks is the use of public DNS servers to connect users to websites, which can mistakenly send browsing activity outside the VPN's encrypted tunnel. ExpressVPN avoids the risks of the public system by installing its own DNS resolvers on every server. This is the key factor behind its clean bill of health in our leak testing. Two other common flaws can lead to VPN leaks: WebRTC traffic and IPv6. The former is a communication protocol used in live streaming and the latter is a new IP standard designed to expand domain availability. Both are nice, but currently optional, so ExpressVPN automatically blocks both to ensure there's no opportunity for leaks to arise. One note about VPN security on iOS: it's a known and continuing problem that iOS VPNs do not prevent many online apps from communicating with Apple directly, outside the VPN tunnel. This risks leaking sensitive data, even with Lockdown Mode active in iOS 16. A blog post by Proton VPN shares a workaround: connect to a VPN server, then turn Airplane Mode on and off again to end all connections that were active before you connected to the VPN. Testing encryption We finished up our battery of security tests by checking out ExpressVPN's encryption directly. Using WireShark, a free packet sniffer, we inspected what it looks like when ExpressVPN transmits data from one of its servers to the internet. The screenshot below shows a data stream encrypted with Lightway UDP. After connecting to ExpressVPN, HTTP packets were rendered unreadable while in transit. Sam Chapman for Engadget That lack of any identifiable information, or even readable information, means encryption is working as intended. We repeated the test several times, always getting the same result. This left us satisfied that ExpressVPN's core features are working as intended. How much does ExpressVPN cost? ExpressVPN subscriptions cost $12.95 per month. Long-term subscriptions can bring the monthly cost down, but the great deals they offer tend to only last for the first billing period. A 12-month subscription costs $99.95 and includes three months for free with your first payment, costing a total of $6.67 per month. The bonus disappears for all subsequent years, raising the monthly cost to $8.33. You can also sign up for 28 months at a cost of $139.72, but this is also once-only — ExpressVPN can only be renewed at the $99.95 per year level. There are two ways to test ExpressVPN for free before making a financial commitment. Users on iOS and Android can download the ExpressVPN app without entering any payment details and use it free for seven days. On any platform, there's a 30-day money-back guarantee, which ExpressVPN has historically honored with no questions asked. You will have to pay before you can use it, though. In our opinion, ExpressVPN's service is solid enough that it's worth paying extra. Perhaps not this much extra, but that depends on what you get out of it. We recommend using the 30-day refund period and seeing how well ExpressVPN works for you. If it's a VPN you can enjoy using, that runs fast and unblocks everything you need, that's worth a server's weight in gold. ExpressVPN side apps and bundles ExpressVPN includes some special features that work mostly or wholly separate from its VPN apps. Some of these come free with a subscription, while others add an extra cost. Every subscription includes the ExpressVPN keys password manager. This is available under its own tab on the Android and iOS apps. On desktop, you'll need to download a separate extension from your browser's store, then sign in using your account activation code. It's available on all Chromium browsers, but not Firefox. Starting in 2025, new subscribers get an eSIM plan through holiday.com, a separate service linked to ExpressVPN. The baseline 1GB holiday eSIM plans last for 5 days and can apply to countries, regions, or the entire world (though it's not clear whether the package deal applies to the regional and global plans). Longer-term plans include larger eSIM plans. You can add a dedicated IP address to your ExpressVPN subscription for an additional cost per month. A dedicated IP lets you use the same IP address every time you connect to ExpressVPN. You can add the address to whitelists on restricted networks, and you're assured to never be blocked because of someone else's bad activity on a shared IP. Unlike many of its competitors, ExpressVPN doesn't currently offer antivirus or online storage services, but there is a comprehensive bundle of ID protection tools called Identity Defender. We haven't reviewed any of these products in detail, but here's a list for reference: ID Alerts will inform you if any of your sensitive information is leaked or misused online. It's free with all plans, but you'll have to enter your personal information on your ExpressVPN account page or a mobile app. ID Theft Insurance grants up to $1 million in identity theft reimbursement and comes free with new ExpressVPN one-year or two-year subscriptions. It's not yet available to those who subscribed before it launched in October 2024. Data Removal scans for your information in data brokerages and automatically requests that it be deleted. It's also free with one-year and two-year plans. Credit Scanner is only available for United States users. It monitors your activity on the three credit bureaus so you can quickly spot any suspicious transactions. The Identity Defender features are currently only available to new ExpressVPN customers in the US. Close-reading ExpressVPN's privacy policy Although we worry that the consolidation of VPN brands under the umbrella of Kape Technologies (ExpressVPN's parent company) will make the industry less competitive, we don't believe it's influencing ExpressVPN to take advantage of its users' privacy. To confirm, and get a full sense of what sort of privacy ExpressVPN promises its users, we set out to read ExpressVPN's privacy policy in detail. It's long, but thankfully aimed at casual users instead of lawyers. You can see it for yourself here. In the introduction, ExpressVPN states that it does not keep either activity logs (such as a user's browsing history while connected to the VPN) or connection logs (such as the duration of a user's session and their IP address, which can be used to extrapolate browsing activity). It then specifies the seven types of data it's legally allowed to collect: Data used to sign up for an account, such as names, emails and payment methods. VPN usage data which is aggregated and can't be traced to any individual. Credentials stored in the ExpressVPN Keys password manager. Diagnostic data such as crash reports, which are only shared upon user request. IP addresses authorized for MediaStreamer, which is only for streaming devices that don't otherwise support VPN apps. Marketing data collected directly from the app — a "limited amount" that's kept anonymous. Data voluntarily submitted for identity theft protection apps. Of those seven exceptions, the only ones that count as red flags are account data and marketing data. Both categories are highly personal and could be damaging if mishandled. Fortunately, complying with subpoenas is not one of the allowed uses listed for either data category, nor does the policy let ExpressVPN sell the data to other private parties. The only really annoying thing here is that if you ask ExpressVPN to delete your personal data, you won't be able to use your account from then on. You aren't even eligible for a refund in this case, unless you're within 30 days of your initial subscription. As for marketing data, ExpressVPN collects device fingerprints and location data when you sign up for an account on its website. The privacy policy also claims this is anonymized, as its "systems are engineered to decouple such data from personally identifiable information." Audits corroborate this, as we'll see in the next section. So, while it would be better if ExpressVPN didn't collect any personal data at all, its practices don't appear to pose a risk to anything you do while using the VPN — just the ExpressVPN website. Privacy audits VPN providers often get third-party accounting firms to audit their privacy policies. The idea is that a well-known firm won't mortgage its reputation to lie on behalf of a VPN, so their results can be trusted. For the last several years, ExpressVPN has had KPMG look over its privacy policy and relevant infrastructure (see "TrustedServer" below). KPMG's most recent report, completed in December 2023 and released in May 2024, found that ExpressVPN had enough internal controls in place that users could trust its privacy policy. The report is freely available to read. This is a very good sign, though we're looking out for a more up-to-date audit soon. TrustedServer "TrustedServer" is a marketing term ExpressVPN uses for its RAM-only server infrastructure. RAM-only servers have no hard drives for long-term storage and return to a standard disk image with every reboot. This makes it theoretically impossible to store user activity logs on them, even if ExpressVPN wanted to do that. The KPMG audit, linked above, reports that TrustedServer works as advertised. Between its many clean privacy audits and the Turkish server incident in 2017, we're prepared to say ExpressVPN is a private VPN, in spite of its aggravating exception for marketing. Can ExpressVPN change your virtual location? Next, we tested whether ExpressVPN can actually convince websites that you're somewhere other than your real location. Our security tests have already proven it can hide your IP address, but it takes more than leak-proofing to fool streaming sites these days — Netflix and the others have gotten very good at combing through metadata to sniff out proxy users. The process for testing this is a lot like how we handled the DNS leak tests: try several different servers and see if we get caught. We checked five sample locations outside the U.S. to see if we a) got into Netflix and b) saw different titles in the library. The results are below. Server Location Unblocked Netflix? Library changed? Canada Y Y United Kingdom Y (second try; Docklands failed) Y Slovakia Y Y India Y Y (different from UK library) Australia Y Y In fifteen tests, ExpressVPN slipped up only once. Docklands, the UK server it chose as the fastest, wasn't able to access Netflix. We switched to a server labeled simply "London" and unblocked it without issue. ExpressVPN can change your virtual location so you can explore the wonderful world of K-drama. Sam Chapman for Engadget All the other locations got us access to an alternate Netflix library on the first try. We even checked whether the India server, which is physically located in the UK, showed us different videos than the UK servers. It did, which makes us even more confident that ExpressVPN's virtual locations are airtight. Investigating ExpressVPN's server network ExpressVPN users can connect to a total of 164 server locations in 105 countries and territories. These locations are reasonably well distributed across the globe, but as with all VPNs, there's a bias toward the northern hemisphere. There are 24 locations in the U.S. alone and a further 66 in Europe. That isn't to say users in the Global South get nothing. ExpressVPN has IP addresses from nine nations in South America (Argentina, Brazil, Bolivia, Chile, Colombia, Ecuador, Peru, Uruguay and Venezuela) and six in Africa (Algeria, Egypt, Ghana, Kenya, Morocco and South Africa). The network even includes Kazakhstan, Uzbekistan and Mongolia, impressive since central Asia may be the region most often shafted by VPNs. However, many of these servers have virtual locations different from their real ones. For those of you choosing a server based on performance instead of a particular IP address, ExpressVPN's website has a helpful list of which servers are virtual. The bad news is that it's a big chunk of the list. A total of 63 ExpressVPN locations are virtual, or 38% of its entire network. To reduce the sting, ExpressVPN takes care to locate virtual servers as close to their real locations as possible. Its virtual locations in Indonesia and India are physically based in Singapore. This isn't always practical, leading to some awkwardness like operating a Ghana IP address out of Germany. But it helps ExpressVPN perform better in the southern hemisphere. Extra features of ExpressVPN Compared to direct competitors like NordVPN and Surfshark, ExpressVPN doesn't have many special features. It's aimed squarely at the casual market and will probably disappoint power users. Having said that, what they do include works well. In this section, we'll run through ExpressVPN's four substantial features outside its VPN servers themselves. Network Lock kill switch "Network Lock" is the name ExpressVPN gives to its kill switch (though it's called "Network Protection" on mobile). A VPN kill switch is a safety feature that keeps you from broadcasting outside the VPN tunnel. If it ever detects that you aren't connected to a legitimate ExpressVPN server, it cuts off your internet access. You won't be able to get back online until you either reconnect to the VPN or disable Network Lock. ExpressVPN's kill switch is called Network Lock on desktop, and Network Protection on mobile (Android pictured) Sam Chapman for Engadget This is important for everyone, not just users who need to hide sensitive traffic. The recently discovered TunnelVision bug theoretically allows hackers to set up fake public wi-fi networks through which they redirect you to equally fake VPN servers, which then harvest your personal information. It's unlikely, but not impossible, and a kill switch is the best way to prevent it — the switch always triggers unless you're connected to a real server in the VPN's network. Like most of ExpressVPN's features, all you can do with Network Lock is turn it on and off. You can also toggle whether you'll still be able to access local devices while the kill switch is blocking your internet — this is allowed by default. Threat manager, ad blocker and parental controls ExpressVPN groups three tools under the heading of "advanced protection" — Threat Manager, an ad blocker and parental controls. Threat Manager consists of two checkboxes: one that blocks your browser from communicating with activity tracking software and one that blocks a list of websites known to be used for malware. Check any of these boxes to use the pre-set blocklists whenever you're connected to ExpressVPN. Sam Chapman for Engadget You can't customize the lists, so you're limited to what ExpressVPN considers worthy of blocking. They share their sources on the website. While the lists are extensive and open-source, they rely on after-the-fact reporting and can't detect and block unknown threats like a proper antivirus. The adblock and parental control options work the same way: check a box to block everything on the list, uncheck it to allow everything through. In tests, the ad blocker was nearly 100% effective against banner ads, but failed to block any video ads on YouTube or Netflix. The parental control option blocks a list of porn sites. It's an easy option for concerned parents, but only works while ExpressVPN is connected. As such, it's meant to be used in conjunction with device-level parental controls that prevent the child from turning off or uninstalling the VPN client. Split tunneling Sometimes, you'll find it helpful to have your device getting online through two different IP addresses at once — one for your home services and one for a location you're trying to spoof. That's where split tunneling is helpful: it runs some apps through the VPN while leaving others unprotected. This can also improve your speeds, since the VPN needs to encrypt less in total. You can configure split tunneling through either a blocklist or an allowlist. Sam Chapman for Engadget ExpressVPN includes split tunneling on Windows, Android and Mac (though only on versions 10 and below). You can only split by app, not by website, but it's still pretty useful. For example, you can have BitTorrent handling a heavy download in the background while you use your browser for innocuous activities that don't need protecting. ExpressVPN Aircove router By now, it should be clear that we find ExpressVPN to be a highly reliable but often unexceptional VPN service. However, there's one area in which it's a clear industry leader: VPN routers. ExpressVPN Aircove is, to our knowledge, the only router with a built-in commercial VPN that comes with its own dashboard interface. Usually, installing a VPN on your router requires tinkering with the router control panel, which turns off all but the most experienced users — not to mention making it a massive pain to switch to a new server location. Aircove's dashboard, by contrast, will be instantly familiar to anyone who already knows how to use an ExpressVPN client. It even allows different devices in your home to connect to different locations through the router VPN. Aircove's biggest drawback is its price. Currently retailing at $189 (not including an ExpressVPN subscription), it's around three times more expensive than an aftermarket router fitted with free VPN firmware. Some of you might still find the convenience worth the one-time payment. ExpressVPN customer support options ExpressVPN's written help pages are some of the best on the market. Its live chat is more of a mixed bag, and complex questions may cause delays. However, it is at least staffed with human agents who aim to reply accurately, rather than resolve your ticket as quickly as possible. You can directly access both live chat and email from ExpressVPN's mobile apps (on desktop, you'll have to go to the website). Sam Chapman for Engadget We approached ExpressVPN's support features with a simple question: "If I requested that ExpressVPN delete all my personal data, would I be able to get a refund for my unused subscription time?" (Remember from the Privacy Policy section that submitting a full deletion request also cancels your ExpressVPN account.) Our first stop was expressvpn.com/support, the written support center and FAQ page. It's divided into setup guides, troubleshooting, account management and information on each of ExpressVPN's products. The setup guides are excellent, including screenshots and clearly written steps; each one includes a video guide for those who learn better that way. Troubleshooting is just as good — no videos, but the same standards of clarity and usefulness prevail. The section starts with general problems, then delves into specific issues you might face on each operating system. Each article clearly derives from a real customer need. The live support experience To get answers on our refund question, we visited the account management FAQs. This section stated that the refund policy only applies within 30 days of purchase. Pretty clear-cut, but we still wanted an answer on our special case, so we contacted live chat by clicking the button at the bottom-right of every FAQ page. Live chat is in the bottom-right corner of every page of expressvpn.com. Sam Chapman for Engadget Live chat starts with an AI assistant, which is not too hard to get past — just ask it a question it can't answer, then click "Transfer to an Agent." We got online with (what claimed to be) a human in less than a minute. Answering the question took longer and involved an uncomfortable 10-minute silence, but we did get a clear verdict from a real person: refunds are within 30 days only, no matter what. If the live chat agent can't answer your question, you'll be redirected to open an email support ticket. Annoyingly, there's no way to go directly to email support through the website or desktop apps, though mobile users have the option to skip directly there. ExpressVPN background check: From founding to Kape Technologies ExpressVPN launched in 2009, which makes it one of the oldest consumer VPNs in continual operation. In more than 15 years of operation, it's never been caught violating its own privacy policy, though its record isn't free of more minor blemishes. Headquarters in the British Virgin Islands Founders Dan Pomerantz and Peter Burchhardt registered the company in the British Virgin Islands from the start to take advantage of that territory's favorable legal environment for online privacy. The BVIs have no law requiring businesses to retain data on their users, and the process for extraditing data is famously difficult, requiring a direct order from the highest court. In 2021, the BVI implemented the Data Protection Act (DPA) [PDF link], which prevents companies based in the territory from accessing data on their users anywhere in the world. It's a great privacy law in theory, modeled on best-in-class legislation in the EU. However, we couldn't find any evidence that its supervising authority — the Office of the Information Commissioner — has a leader or staff. In other words, while ExpressVPN is not legally required to log any data on its users, there's technically nobody stopping them from doing so. Whether you trust the jurisdiction depends on whether you trust the company itself. Let's see what the other evidence says. Security and privacy incidents Two significant incidents stand out from ExpressVPN's 16-year history. In 2017, when Andrei Karlov, Russia's ambassador to Turkey, was shot to death at an art show. Turkish police suspected someone had used ExpressVPN to mask their identity while they deleted information from social media accounts belonging to the alleged assassin. To investigate, they confiscated an ExpressVPN server to comb for evidence. They didn't find anything. A police seizure is the best possible test of a VPN's approach to privacy. The provider can't prepare beforehand, fake anything, or collude with investigators. The Turkey incident is still one of the best reasons to recommend ExpressVPN, though eight years is a long time for policy to change. The second incident began in March 2024, when a researcher at CNET informed ExpressVPN that its version 12 for Windows occasionally leaked DNS requests when users enabled the split tunneling feature. While these users remained connected to an ExpressVPN server, their browsing activity was often going directly to their ISP, unmasked. The bug only impacted a few users, and to their credit, ExpressVPN sprang into action as soon as they learned about it. The team had it patched by April, as confirmed by the researcher who initially discovered the vulnerability. But while their quick and effective response deserves praise, it's still a mark against them that a journalist noticed the bug before they did. Kape Technologies ownership and management questions In 2021, an Israeli-owned, UK-based firm called Kape Technologies purchased a controlling interest in ExpressVPN. In addition to ExpressVPN, privately held Kape owns CyberGhost, Private Internet Access, and Zenmate (before it merged into CyberGhost). As shown on its website, it also owns Webselenese, publisher of VPN review websites WizCase and vpnMentor, which poses an apparent conflict of interest. When reached for comment, a representative for ExpressVPN said that "ExpressVPN does not directly engage with, nor seek to influence, the content on any Webselenese site," and pointed us to disclosure statements on the websites in question — here's one example. Even so, it's a good reminder not to take VPN reviews at face value without knowing who's behind them (Engadget is owned by Yahoo, which does not own any VPNs). Diving deeper into the background of Kape's ownership will lead you to owner Teddy Sagi. Go back far enough, and you'll see he did prison time in Israel and was mentioned in the Pandora Papers, among other things. More recently, headlines about the billionaire have focused more his businesses in the online gambling and fintech arenas, as well as his real estate ventures. An ExpressVPN representative told us that "Kape's brands continue to operate independently," and our investigation bore that out — we couldn't find any proof that Kape or Sagi have directly attempted to influence ExpressVPN's software or daily operations. Closer to the immediate day-to-day operations of ExpressVPN was the company's employment of Daniel Gericke as CTO from 2019 through 2023. During that time, the US Justice Department announced it had fined Gericke and two others for their previous employment on a surveillance operation called Project Raven, which the United Arab Emirates (UAE) used to spy on its own citizens. The revelation prompted a public response from ExpressVPN defending its decision to hire Gericke, arguing that "[t]he best goalkeepers are the ones trained by the best strikers." ExpressVPN's representative confirmed that the company still stands by that linked statement. Gericke parted ways with ExpressVPN in October 2023, per his LinkedIn profile. While we don't know what we don't know, we can say that ExpressVPN has not notably changed its public-facing security and privacy policies during the time it's been connected to Kape, Sagi, or Gericke. In the end, how much ExpressVPN's history matters to you is a personal choice. If you object to any current or past actions by Kape Technologies or Teddy Sagi, there are other premium VPN options you might prefer. If you need more information to make up your mind, we recommend reading through CNET's 2022 deep dive on ExpressVPN's corporate history. Final verdict ExpressVPN is the VPN we most often recommend to beginners. It takes zero training to use, and consistently gets past filters on streaming sites. It also runs in the background with virtually no impact. If anything is worth the high price of admission, it's the excellent speeds distributed evenly across the worldwide server network. However, for certain specific cases, ExpressVPN may not be the best choice. There's no way to set up your own server locations, like NordVPN offers, and no double VPN connections, like you can build for yourself on Surfshark. Its corporate background is more suspect than the entities backing Proton VPN, and unlike Mullvad, ExpressVPN doesn't work in China — it's so well-known that the government targets its servers specifically. We suggest going with ExpressVPN for general online privacy, for spoofing locations in your home country while traveling, or if you regularly need to unblock sites in other countries. That encompasses 19 of every 20 users, which is fine by us, as ExpressVPN is a great service. It's just more of a reliable old screwdriver than a multi-tool.

Transparent design is the intentional use of see-through or translucent materials and visual strategies to evoke openness, honesty, and fluidity in both spatial and product design. It enhances light flow, visibility, and interaction, blurring boundaries between spaces or revealing inner layers of products. In interiors, this manifests through glass walls, acrylic dividers, and open layouts that invite natural light and visual connection. Transparency in product design often exposes internal mechanisms in products, fostering trust and curiosity by making functions visible. It focuses on simplicity, clarity, and minimalist form, creating seamless connections between objects and their environments. Let’s now explore how transparency shapes the function, experience, and emotional impact of spatial and product design. Transparent Spatial Design Transparency in spatial design serves as a powerful architectural language that transcends mere material choice, creating profound connections between spaces and their inhabitants. By employing translucent or clear elements, designers can dissolve traditional boundaries, allowing light to penetrate deeply into interiors while establishing visual relationships between previously separated areas. This permeability creates a dynamic spatial experience where environments flow into one another, expanding perceived dimensions and fostering a sense of openness. The strategic use of transparent elements – whether through glass partitions, open floor plans, or permeable screens – transforms rigid spatial hierarchies into fluid, interconnected zones that respond to contemporary needs for flexibility and connection with both surrounding spaces and natural environments. Beyond its physical manifestations, transparency embodies deeper philosophical principles in design, representing honesty, clarity, and accessibility. It democratizes space by removing visual barriers that traditionally signaled exclusion or privacy, instead promoting inclusivity and shared experience. In public buildings, transparent features invite engagement and participation, while in residential contexts, they nurture connection to nature and enhance wellbeing through abundant natural light. This approach challenges designers to thoughtfully balance openness with necessary privacy, creating nuanced spatial sequences that can reveal or conceal as needed. When skillfully implemented, transparency becomes more than an aesthetic choice, it becomes a fundamental design strategy that shapes how we experience, navigate, and emotionally respond to our built environment. 1. Expands Perception of Space Transparency in spatial design enhances how people perceive space by blurring the boundaries between rooms and creating a seamless connection between the indoors and the outdoors. Materials like glass and acrylic create visual continuity, making interiors feel larger, more open, and seamlessly integrated. This approach encourages a fluid transition between spaces, eliminates confinement, and promotes spatial freedom. As a result, transparent design contributes to an inviting atmosphere while maximising natural views and light penetration throughout the environment. Nestled in St. Donat near Montreal, the Apple Tree House by ACDF Architecture is a striking example of transparent design rooted in emotional memory. Wrapped around a central courtyard with a symbolic apple tree, the low-slung home features expansive glass walls that create continuous visual access to nature. The transparent layout not only blurs the boundaries between indoors and outdoors but also transforms the apple tree into a living focal point and is visible from multiple angles and spaces within the house. This thoughtful transparency allows natural light to flood the interiors while connecting the home’s occupants with the changing seasons outside. The home’s square-shaped plan includes three black-clad volumes that house bedrooms, a lounge, and service areas. Despite the openness, privacy is preserved through deliberate wall placements. Wooden ceilings and concrete floors add warmth and texture, but it’s the full-height glazing that defines the home that frames nature as a permanent, ever-evolving artwork at its heart. 2. Enhances the Feeling of Openness One of the core benefits of transparent design is its ability to harness natural light, transforming enclosed areas into luminous, uplifting environments. By using translucent or clear materials, designers reduce the need for artificial lighting and minimize visual barriers. This not only improves energy efficiency but also fosters emotional well-being by connecting occupants to daylight and exterior views. Ultimately, transparency promotes a feeling of openness and calm, aligning with minimalist and modern architectural principles. The Living O’Pod by UN10 Design Studio is a transparent, two-story pod designed as a minimalist retreat that fully immerses its occupants in nature. Built with a steel frame and glass panels all around, this glass bubble offers uninterrupted panoramic views of the Finnish wilderness. Its remote location provides the privacy needed to embrace transparency, allowing residents to enjoy stunning sunrises, sunsets, and starry nights from within. The open design blurs the line between indoors and outdoors, creating a unique connection with the environment. Located in Repovesi, Finland, the pod’s interiors feature warm plywood floors and walls that complement the natural setting. A standout feature is its 360° rotation, which allows the entire structure to turn and capture optimal light and views throughout the day. Equipped with thermal insulation and heating, the Living O’Pod ensures comfort year-round and builds a harmonious relationship between people and nature. 3. Encourages Interaction Transparent design reimagines interiors as active participants in the user experience, rather than passive backgrounds. Open sightlines and clear partitions encourage movement, visibility, and spontaneous interaction among occupants. This layout strategy fosters social connectivity, enhances spatial navigation, and aligns with contemporary needs for collaboration and flexibility. Whether in residential, commercial, or public spaces, transparency supports an intuitive spatial flow that strengthens the emotional and functional relationship between people and their environment. The Beach Cabin on the Baltic Sea, designed by Peter Kuczia, is a striking architectural piece located near Gdansk in northern Poland. This small gastronomy facility combines simplicity with bold design, harmoniously fitting into the beach environment while standing out through its innovative form. The structure is composed of two distinct parts: an enclosed space and an expansive open living and dining area that maximizes natural light and offers shelter. This dual arrangement creates a balanced yet dynamic architectural composition that respects the surrounding landscape. A defining feature of the cabin is its open dining area, which is divided into two sections—one traditional cabin-style and the other constructed entirely of glass. The transparent glass facade provides uninterrupted panoramic views of the Baltic Sea, the shoreline, and the sky, enhancing the connection between interior and nature. Elevated on stilts, the building appears to float above the sand, minimizing environmental impact and contributing to its ethereal, dreamlike quality. Transparent Product Design In product design, transparency serves as both a functional strategy and a powerful communicative tool that transforms the relationship between users and objects. By revealing internal components and operational mechanisms through clear or translucent materials, designers create an immediate visual understanding of how products function, demystifying technology and inviting engagement. This design approach establishes an honest dialogue with consumers, building trust through visibility rather than concealment. Beyond mere aesthetics, transparent design celebrates the beauty of engineering, turning circuit boards, gears, and mechanical elements into intentional visual features that tell the product’s story. From the nostalgic appeal of see-through gaming consoles to modern tech accessories, this approach satisfies our innate curiosity about how things work while creating a more informed user experience. The psychological impact of transparency in products extends beyond functional clarity to create deeper emotional connections. When users can observe a product’s inner workings, they develop increased confidence in its quality and craftsmanship, fostering a sense of reliability that opaque designs often struggle to convey. This visibility also democratizes understanding, making complex technologies more accessible and less intimidating to diverse users. Transparent design elements can evoke powerful nostalgic associations while simultaneously appearing futuristic and innovative, creating a timeless appeal that transcends trends. By embracing transparency, designers reject the notion that complexity should be hidden, instead celebrating the intricate engineering that powers our everyday objects. This philosophy aligns perfectly with contemporary values of authenticity and mindful consumption, where users increasingly seek products that communicate honesty in both form and function. 1. Reveals Functionality Transparent product design exposes internal components like wiring, gears, or circuits, turning functional parts into visual features. This approach demystifies the object, inviting users to understand how it works rather than hiding its complexity. It fosters appreciation for craftsmanship and engineering while encouraging educational curiosity. By showcasing what lies beneath the surface, designers build an honest relationship with consumers that is based on clarity, trust, and visible function. Packing a backpack often means tossing everything in and hoping for the best—until you need something fast. This transparent modular backpack concept reimagines that daily hassle with a clear, compartmentalized design that lets you see all your gear at a glance. No more digging through a dark abyss—every item has its visible place. The bag features four detachable, differently sized boxes that snap together with straps, letting you customize what you carry. Grab just the tech module or gym gear block and go—simple, efficient, and streamlined. Unlike traditional organizers that hide contents in pouches, the transparent material keeps everything in plain sight, saving time and frustration. While it raises valid concerns around privacy and security, the clarity and convenience it offers make it ideal for fast-paced, on-the-go lifestyles. With form meeting function, this concept shows how transparent design can transform not just how a bag looks, but how it works. 2. Enhances User Engagement When users can see how a product operates, they feel more confident using it. Transparent casings invite interaction by reducing uncertainty about internal processes. This visible clarity reassures users about the product’s integrity and quality, creating a psychological sense of openness and reliability. Especially in tech and appliances, this strategy deepens user trust and adds emotional value by allowing a more intimate connection with the design’s purpose and construction. The transparent Sony Glass Blue WF-C710N earbuds represent something more meaningful than a mere aesthetic choice, embodying a refreshing philosophy of technological honesty. While most devices conceal their inner workings behind opaque shells, Sony’s decision to reveal the intricate circuitry and precision components celebrates the engineering artistry that makes these tiny audio marvels possible. As you catch glimpses of copper coils and circuit boards through the crystal-clear housing, there’s a renewed appreciation for the invisible complexity that delivers your favorite music, serving as a visual reminder that sometimes the most beautiful designs are those that have nothing to hide. 3. Celebrates Aesthetic Engineering Transparency turns utilitarian details into design features, allowing users to visually experience the beauty of inner mechanisms. This trend, seen in everything from vintage electronics to modern gadgets and watches, values technical artistry as much as outer form. Transparent design redefines aesthetics by focusing on the raw, mechanical truth of a product. It appeals to minimalism and industrial design lovers, offering visual depth and storytelling through exposed structure rather than decorative surface embellishment. DAB Motors’ 1α Transparent Edition brings retro tech flair into modern mobility with its striking transparent bodywork. Inspired by the see-through gadgets of the ”90s—like the Game Boy Color and clear Nintendo controllers—this electric motorcycle reveals its inner mechanics with style. The semi-translucent panels offer a rare peek at the bike’s intricate engineering, blending nostalgia with innovation. Carbon fiber elements, sourced from repurposed Airbus materials, complement the lightweight transparency, creating a visual experience that’s both futuristic and rooted in classic design aesthetics. The see-through design isn’t just for looks—it enhances the connection between rider and machine. Exposed components like the integrated LCD dashboard, lenticular headlight, and visible frame structure emphasize function and precision. This openness aligns with a broader transparent design philosophy, where clarity and honesty in construction are celebrated. The DAB 1α turns heads not by hiding complexity, but by proudly displaying it, making every ride a statement in motion. Beyond just materials, transparent design also reflects a deeper design philosophy that values clarity in purpose, function, and sustainability. It supports minimalist thinking by focusing on what’s essential, reducing visual clutter, and making spaces or products easier to understand and engage with. Whether in interiors or objects, transparency helps create a more honest, functional, and connected user experienceThe post Transparent Design: How See-Through Materials Are Revolutionizing Architecture & Product Design first appeared on Yanko Design.

Given their abundance in American backyards, gardens and highway corridors these days, it may be surprising to learn that white-tailed deer were nearly extinct about a century ago. While they currently number somewhere in the range of 30 million to 35 million, at the turn of the 20th century, there were as few as 300,000 whitetails across the entire continent: just 1% of the current population. This near-disappearance of deer was much discussed at the time. In 1854, Henry David Thoreau had written that no deer had been hunted near Concord, Massachusetts, for a generation. In his famous “Walden,” he reported: “One man still preserves the horns of the last deer that was killed in this vicinity, and another has told me the particulars of the hunt in which his uncle was engaged. The hunters were formerly a numerous and merry crew here.” But what happened to white-tailed deer? What drove them nearly to extinction, and then what brought them back from the brink? As a historical ecologist and environmental archaeologist, I have made it my job to answer these questions. Over the past decade, I’ve studied white-tailed deer bones from archaeological sites across the eastern United States, as well as historical records and ecological data, to help piece together the story of this species. Precolonial rise of deer populations White-tailed deer have been hunted from the earliest migrations of people into North America, more than 15,000 years ago. The species was far from the most important food resource at that time, though. Archaeological evidence suggests that white-tailed deer abundance only began to increase after the extinction of megafauna species like mammoths and mastodons opened up ecological niches for deer to fill. Deer bones become very common in archaeological sites from about 6,000 years ago onward, reflecting the economic and cultural importance of the species for Indigenous peoples. Despite being so frequently hunted, deer populations do not seem to have appreciably declined due to Indigenous hunting prior to AD 1600. Unlike elk or sturgeon, whose numbers were reduced by Indigenous hunters and fishers, white-tailed deer seem to have been resilient to human predation. While archaeologists have found some evidence for human-caused declines in certain parts of North America, other cases are more ambiguous, and deer certainly remained abundant throughout the past several millennia. Human use of fire could partly explain why white-tailed deer may have been resilient to hunting. Indigenous peoples across North America have long used controlled burning to promote ecosystem health, disturbing old vegetation to promote new growth. Deer love this sort of successional vegetation for food and cover, and thus thrive in previously burned habitats. Indigenous people may have therefore facilitated deer population growth, counteracting any harmful hunting pressure. More research is needed, but even though some hunting pressure is evident, the general picture from the precolonial era is that deer seem to have been doing just fine for thousands of years. Ecologists estimate that there were roughly 30 million white-tailed deer in North America on the eve of European colonization—about the same number as today. A 16th-century engraving depicts Indigenous Floridians hunting deer while disguised in deerskins. [Photo: Theodor de Bry/DEA Picture Library/De Agostini/Getty Images] Colonial-era fall of deer numbers To better understand how deer populations changed in the colonial era, I recently analyzed deer bones from two archaeological sites in what is now Connecticut. My analysis suggests that hunting pressure on white-tailed deer increased almost as soon as European colonists arrived. At one site dated to the 11th to 14th centuries (before European colonization) I found that only about 7% to 10% of the deer killed were juveniles. Hunters generally don’t take juvenile deer if they’re frequently encountering adults, since adult deer tend to be larger, offering more meat and bigger hides. Additionally, hunting increases mortality on a deer herd but doesn’t directly affect fertility, so deer populations experiencing hunting pressure end up with juvenile-skewed age structures. For these reasons, this low percentage of juvenile deer prior to European colonization indicates minimal hunting pressure on local herds. However, at a nearby site occupied during the 17th century—just after European colonization—between 22% and 31% of the deer hunted were juveniles, suggesting a substantial increase in hunting pressure. This elevated hunting pressure likely resulted from the transformation of deer into a commodity for the first time. Venison, antlers and deerskins may have long been exchanged within Indigenous trade networks, but things changed drastically in the 17th century. European colonists integrated North America into a trans-Atlantic mercantile capitalist economic system with no precedent in Indigenous society. This applied new pressures to the continent’s natural resources. Deer—particularly their skins—were commodified and sold in markets in the colonies initially and, by the 18th century, in Europe as well. Deer were now being exploited by traders, merchants and manufacturers desiring profit, not simply hunters desiring meat or leather. It was the resulting hunting pressure that drove the species toward its extinction. 20th-century rebound of white-tailed deer Thanks to the rise of the conservation movement in the late 19th and early 20th centuries, white-tailed deer survived their brush with extinction. Concerned citizens and outdoorsmen feared for the fate of deer and other wildlife, and pushed for new legislative protections. The Lacey Act of 1900, for example, banned interstate transport of poached game and—in combination with state-level protections—helped end commercial deer hunting by effectively de-commodifying the species. Aided by conservation-oriented hunting practices and reintroductions of deer from surviving populations to areas where they had been extirpated, white-tailed deer rebounded. The story of white-tailed deer underscores an important fact: Humans are not inherently damaging to the environment. Hunting from the 17th through 19th centuries threatened the existence of white-tailed deer, but precolonial Indigenous hunting and environmental management appear to have been relatively sustainable, and modern regulatory governance in the 20th century forestalled and reversed their looming extinction.
