Here's the inside scoop on what ZDNET readers snagged this past month (including during holiday sales). And some of these products are still on sale, too.

The Walking Dead: The Ones Who LiveCredit: AMCIn my review of the finale of The Walking Dead: The Ones Who Live, I open with a statement that I think a lot of my readers will agree with: Gimple-speak ruins everything.Thus began a rather scathing takedown of the highly-anticipated Rick and Michonne spinoff. Wed all waited years for this reunion and to learn more about the mysterious and powerful CRM, only to get one of the worst seasons of The Walking Dead ever made. No, it wasnt as bad as the last few seasons of Fear The Walking Dead, but Id lost hope for that show long ago. I was actually excited to see what happened with Rick Grimes (Andrew Lincoln) and Michonne (Danai Gurira).The crushing disappointment at what we were given after all this time (both our time and the in-universe fictional time that had passed) was enormous and painful. I am certainly a harsh critic when it comes to AMCs zombie empire, but my criticism comes from a place of love. I want these shows to be great, and I am constantly baffled at the low-effort nonsense that goes into each new offering.This could have been so much more. It deserved to be so much more. Fans deserved more. Andrew Lincoln and Danai Gurira deserved more, I wrote at the time. Too neat, too convenient, too poorly written, too rushed. I am Jacks crushing sense of disappointment.Now you can experience that same feeling. All six episodes (a disappointing number in and of itself) are available today on Netflix. And perhaps you will like it better than I did. I am, it appears, in the minority in my sense of betrayal at how badly they dropped the ball. On Rotten Tomatoes, it has an 88% with critics and an 80% with fans, which is rather puzzling to me.Read More: Todays Wordle #1304 Hints, Clues And Answer For Monday, January 13thThe Ones Who LiveCredit: AMCAnd sure, it was nicely filmed. There are some fun action set-pieces. The cinematography is, at times, quite good. Lincoln and Gurira and the supporting cast do a pretty good job. Its just filled with so many plot conveniences, rushed storylines and that hideously botched ending that I cant ever recommend it. Of course, these are all things that every TWD show engages in with gusto. Nobody talks like real people. Nobody makes sensible, logical choices. They kill off the best characters shortly after introducing them and hold on to the worst characters for far too long.Before you accuse me of wanting plausibility in a zombie apocalypse show, Ill turn your attention to this post I recently wrote about what The Walking Dead could learn from Netflixs other new show, American Primeval, and how it pertains to small details in The Walking Dead, like costumes and makeup and the importance of creating a believable and immersive fictional world.What did you think of The Ones Who Live? Or are you only now watching it thanks to its release on Netflix? Either way, chime in on Twitter, Instagram, Bluesky or Facebook.

I have been much-criticized for saying that I dont much care for the romance between Rick and Michonne, and that it felt rushed from the start and that their chemistry never clicked for me. But even though all thats trueand my opinionthats not what actually hurt The Ones Who Live. It was everything else. The bad scripts. The logical leaps. The shortcuts. The weird, stilted dialogue. And it was just way, way too easy for our heroes to overcome such enormous obstacles. Barely an inconvenience!

The big picture: Traditional AI-based image tools often focus on generating images from scratch using text prompts, which has invited controversy due to copyright concerns. Firefly, however, leverages prompts to make complex edits to existing images within Adobe programs like Photoshop and Illustrator. Users can seamlessly add objects while maintaining consistent lighting, introduce new patterns, remove backgrounds, or extend image boundaries though sometimes with unintentionally humorous results. Adobe has added numerous features to its Firefly GenAI suite since its introduction in 2023. The latest update enables companies to adjust images in bulk and when they say bulk they are claiming by the thousands, if necessary. Known as Firefly Bulk Create, this tool aims to accelerate advertising and messaging campaigns by making image alterations more efficient. While some critics worry that this technology might erode human artistry in advertising, Adobe's press release promotes the new tools as a means to cut through tedious work.According to a now-removed Adobe press release (perhaps deemed too contentious for its audience?), the Bulk Create feature can automate tasks like removing backgrounds, resizing images, and making other adjustments that would otherwise be repetitive if done manually. The functionality could facilitate large-scale communication by helping companies and organizations quickly customize assets for multiple channels and platforms.Currently, Bulk Create appears as two distinct functions within the Firefly web app. One function enables users to upload images, change their backgrounds, and save copies in batches as PNGs or JPEGs. The other function automatically adjusts image dimensions to fit the requirements of social media platforms like TikTok, Instagram, and Facebook by stretching or resizing backgrounds.In addition to Bulk Create, Adobe plans to introduce a new method for automating brand layouts in Firefly next month. This feature, entering beta, will integrate InDesign APIs with various data sources, allowing companies to arrange text and images into templates for posters, magazines, and other advertising formats.Although Adobe mostly advertises its AI tools by discussing how it reduces the tedious aspects of editing pictures on a mass scale, the company still mentions the controversial use of GenAI for creating new images or performing tasks traditionally handled by human artists. // Related StoriesFor instance, Adobe is launching GenAI avatars in beta this month, featuring capabilities like text-to-speech and automatic animation. Additionally, AI-based translation, dubbing, and lip-syncing for videos are expected to exit beta soon.Since the launch of Firefly, Adobe has attempted to address fears about copyright and the potential impact of GenAI on human creativity. The toolset is partially trained on stock photos, and Adobe has promised to compensate artists who contribute to improving the AI. Despite this, skepticism remains prevalent, as the debate over the ethical implications of GenAI remains contentious.

Gross Biofilms, unwashed hands: FDA found violations at McDonalds ex-onion supplier The outbreak sickened at least 104 across 14 states, killing one and hospitalizing 34.

Credit: Getty | Scott Olson Story textSizeSmallStandardLargeWidth *StandardWideLinksStandardOrange* Subscribers only Learn moreThe onion supplier behind a deadly E. coli outbreak linked to McDonald's Quarter Pounders this past fall had numerous health and sanitation violations, including employees with unwashed hands, dirty equipment, and puddles of Listeria bacteria. That's according to a Food and Drug Administration inspection report that was obtained by CBS News via a Freedom of Information Act request.On October 22, the Centers for Disease Control and Prevention announced the outbreak investigation, which at that time had only been linked to 48 illnesses across 10 states, including one death. The slivered onions on the fast-food giant's popular Quarter Pounder burgers were an immediate suspect. McDonald's temporarily pulled the burgers from the menu in affected states, and the supplier of the suspect onions, Taylor Farms of Colorado, swiftly recalled thousands of cases. Ultimately, 104 were sickened across 14 states, with 34 people hospitalized and one dead.On October 28, the FDA began a multi-day inspection of Taylor Farms' facility in Colorado Springs, in which inspectors found numerous violations. The facility processes "ready-to-eat" (RTE) produce, like the cut onions, that do not go through a lethal treatment step for any environmental pathogens before being sold to consumers. This makes any unsanitary conditions in the facility particularly risky for food safety.Inspection findingsInspectors found clear evidence of such risks. Numerous surfaces and pooled water in non-food contact areas of the facility tested positive for Listeria bacteria, a potentially deadly food pathogen behind an outbreak linked to Boar's Head meat last year. However, corrective action procedures were not properly implemented by Taylor Farms, FDA inspectors found.The inspectors also noted debris and dirty equipmentafter the employees had allegedly done cleaning procedures. "We observed numerous equipment with apparent biofilm and large amounts of food debris present after the firms post-operation cleans," the report notes. Taylor Farms had graded the cleaning procedures as "Pass" even though the equipment was left visibly dirty and should have been graded as "Fail," the inspectors wrote.Perhaps most concerning, FDA inspectors noted that employees were never seen washing their hands. Instead, they wore gloves, and if they touched dirty surfaces or items, they would simply put hand sanitizer on their dirty gloves and carry on. What they should have been doing was removing their dirty gloves, washing their hands, and getting clean gloves. However, the FDA inspectors never saw this happen, and managers confirmed that hand sanitizing gloves was common practice.The inspectors also noted that the facility's equipment was always wet. Employees applied sanitizing solutions on knives and other equipment used to dice and chop fresh produce. The sanitizing solution is meant to be air-dried before use, but Taylor Farms employees immediately used the equipmentstill dripping with sanitizing solutionto cut RTE produce.On one day of the inspection, FDA agents saw employees chop RTE lettuce with equipment that was wet with sanitizing solution at the maximum concentration, which was 200 ppm. In another instance, the inspectors saw an employee mix cleaning chemicals together to make a sanitizing solution, which the employee said was done "routinely." When inspectors asked about the mixture, Taylor Farms "could not find the source of this recipe," nor could they find the manufacturer label or other information stating the mixture was designed for use.Highest expectationsIn a statement to CBS, Taylor Farms said that it "immediately took steps to address" the problems found in the FDA's inspection, which resulted in no "administrative or regulatory action" against the company."Taylor Farms is confident in our best-in-class food safety processes, and in turn, the quality and safety of our products," the company said in the statement. "As is common following an inspection, FDA issued observations of conditions that could be improved at one of our facilities." The company added that "no illnesses or public health threat has been linked to these observations" in the inspection.McDonald's, meanwhile, said it had stopped getting onions from the facility."We hold our suppliers to the highest expectations and standards of food safety. Prior to this inspection, and unrelated to its findings, McDonald's stopped sourcing from Taylor Farms' Colorado Springs facility," McDonald's said in a statement.Beth MoleSenior Health ReporterBeth MoleSenior Health Reporter Beth is Ars Technicas Senior Health Reporter.

Meta owns social media platforms including Facebook and InstagramJRdes / ShutterstockIn 2024, Meta allowed more than 3300 pornographic ads many featuring AI-generated content on its social media platforms, including Facebook and Instagram.The findings come from a report by AI Forensics, a European non-profit organisation focused on investigating tech platform algorithms. The researchers also discovered an inconsistency in Metas content moderation policies by re-uploading many of the same explicit images as standard posts on Instagram and Facebook. Unlike the ads, those posts were swiftly removed for violating Metas Community Standards. AdvertisementIm both disappointed and not surprised by the report, given that my research has already exposed double standards in content moderation, particularly in the realms of sexual content, says Carolina Are at Northumbria Universitys Centre for Digital Citizens in the UK.The AI Forensics report focused on a small sample of ads aimed at the European Union. It found that the explicit ads allowed by Meta primarily targeted middle-aged and older men with promotions for dubious sexual enhancement products and hook-up dating websites, with a total reach of more than 8.2 million impressions.Such permissiveness reflects a broader double standard in content moderation, says Are. Tech platforms often block content by and for women, femme-presenting and LGBTQIA+ users, she says. That double standard extends to male and female sexual health. An example is lingerie and period-related ads being [removed] from Meta, while ads for Viagra are approved, she says. Receive a weekly dose of discovery in your inbox.Sign up to newsletterIn addition to finding AI-generated imagery in the ads, the AI Forensics team also discovered audio deepfakes: in some ads for sexual enhancement medication, for example, pornographic visuals were overlaid with the digitally manipulated voice of actor Vincent Cassel.Meta prohibits the display of nudity or sexual activity in ads or organic posts on our platforms, and we are removing the violating content that was shared with us, says a Meta spokesperson. Bad actors are constantly evolving their tactics to avoid enforcement, which is why we continue to invest in the best tools and technology to help identify and remove violating content.The report coincides with Meta CEO Mark Zuckerberg announcing that the company will be getting rid of its fact-checking teams in favour of crowdsourced community notes.If we want to sound really dystopian and at this stage given Zuckerbergs latest decision to remove fact-checkers I think we have reason to be we can even say that Meta is as quick to strip individual, marginalised users of their agency as it is to take money from dubious ads, says Are.Topics:

Nicola Prentis doesn't enjoy spending time messaging on dating apps and prefers to meet in person.She created a poll on Hinge to help her find men who are happy to meet face-to-face early on.The poll is helping her find spontaneous men who have time to go on dates.I've noticed that people on dating apps tend to fall into two categories: "messagers" and "meeters." The first kind wants to message for a while to make sure there's enough common ground to meet up in person. The second type is like me, people who want to meet face-to-face as soon as possible. For me, that's the only way to tell if there's a connection worth investing time in. After a two-year break from dating apps, the one thing I was sure of when I downloaded Hinge in 2024 was that I wanted to spend as little time chatting on the app as possible. My previous experiences with lengthy text conversations that dragged on for weeks, only to fizzle out or lead to disappointing dates, had left me thoroughly burned out on online dating.In the past, I only brought up the idea of meeting in person when it felt natural.But even that was often a waste of time, as a lot of men never seemed interested in an actual date. Maybe they were married, or maybe they used dating apps as an ego boost or for entertainment on their phones. I run my own company and work from home, which offers few opportunities to meet people organically, so I view online dating as a shortcut to real-life dating, not a replacement for it.To cut to the chase sooner, I've started using one of Hinge's prompts the poll option and it's proving efficient at getting me the matches I want. The poll is simple but effective at getting to an IRL dateThe poll reads: Do you want to meeta) Today?b) Tomorrow?c) Swap "How are you?" messages for weeks on end?If someone votes for either of the first two options, I always make it a match and reply. Best of all, I can get straight to the point and make arrangements for how to meet instead of wasting time in chit-chat. Dating coaches and matchmakers told Business Insider that it's important to ask pre-date questions to ensure safety and compatibilitybefore agreeing to meet in person. Suggestions included asking for their last name and looking it up on LinkedIn to confirm their age and occupation, as well as hopping on a phone call before the first date. I only ever meet in busy public places to keep myself safe.As I've found that a lot of guys I've spoken to don't really read profiles, a poll works because it spotlights the fact that I prefer to meet than chat. It's not perfect I don't think any method on a dating app ever could be. But, so far, I've ended up meeting over half the guys who took the initiative to vote, successfully avoiding endless messaging.It's true that some people vote and never reply. But one of the best things about this approach is that I've invested nothing. I barely notice if they disappear before we meet. My method helps repel the wrong guysIt might seem like my poll signals that I'm only looking for hookups, but so far, that's not been my experience. A possible downside is that I live in a major tourist destination, so I often get men who are just passing through on vacation. But that doesn't bother me. It reminds me of the years I spent traveling and how life-enriching it can be to meet someone you hit it off with instantly, even if your paths only cross for a few hours. In fact, one hiking date led to drinks that same evening. It went so well that I'm now planning to visit him on the third date. To my surprise, some men choose the third option of sending endless text messages. At first, I thought it was their way of jokily showing they got my point and were on board. But no. Nine times out of 10, those guys weren't proactive about meeting, so now I skip them completely. An unintended benefit of the poll is it makes me much less of a target for scammers and married men. After all, both always have excuses for why they can't meet in real life.So far, I've been going on dates with spontaneous action-takers who prefer to do something rather than just talk about doing it. Crucially, they actually have time in their lives for dating and prioritise it. All of these qualities are what I'm looking for, and mercifully, they mean I spend a maximum of 15 minutes a week on the app. Got a personal essay about dating that you want to share?

Stop-motion animation is a prospect challenging enough for any studio, even Aardman, which has been pioneering the form for decades at this point. But what happens when you decide to bring back a villain whos famous for not being able to say a single word, can barely move any part of their face, and mostly gets by by standing around and blinking? That has been one of the most challenging aspects really, of the whole movie, Nick Park recently told Inverse about the decision to bring back Feathers McGraw, the villain of Wallace & Gromits second TV outing, The Wrong Trousers, decades later for Vengeance Most Fowl, now streaming worldwide on Netflix. At least Gromit has a brow he can move up. He can understand thoughts more clearly. Its all about the simplicity of how Feathers moves, the deliberate and small movements. A look here, a blink. Minimalism, really. As Park explained, Wallace & Gromit is no stranger to silent characters, given that the titular second half of the duo is a dog who cant talk. But Gromit is still surprisingly articulate: his ears can move, his eyes are similar to any other human characters, he can move different parts of his face, and has full hands, feet, and even a neck to move his body about with and express his emotions clearly to the audience. Feathers, on the other hand, is a tiny stylized penguin (occasionally disguised as a rooster). His eyes are tiny beads, his entire body is shaped like a bottle. If Feathers wants to use body language, hes got his flippers, which are restricted in their own ways, and then hes got moving his whole body at once. And yet, in bothWrong Trousers andVengeance Most Fowl, he remains utterly charming, occasionally sinister, and still completely communicable to the audience. Despite there being over three decades time between his on-screen appearances, the techniques Park (and now hisVengeance Most Fowl co-director, Merlin Crossingham) used to make Feathers feel akin to any other character inWallace & Gromit have remained the same. We use camera moves, the sound, Crossingham explained. Hes a very cinematic character because we rely, as filmmakers, on all those tricks to make him the hero/villain that you see and love to hate.The more things change, the more some things stay the same. But forWallace & Gromit, and Aardman more generally, it speaks to the timelessness of the craft involved in this kind of traditional hand animation. Back when Toy Story first came out in the 90s, a studio like us, were thinking, Oh, boy, how long do we have left? Park concluded. But we kept going. As long as youre telling good stories, compelling stories with compelling characters, then its just the technique really. All these years later, Feathers remains as compelling as he has ever beenand still up to those same cinematic tricks.Wallace & Gromit: Vengeance Most Fowl is now streaming on Netflix.

During their prime, the Vikings mastered the seas and went on to make wide-spanning voyages by boat. But how exactly did they know where they were going? A recent study, focused on a set of medieval stone disks found in Ukraine, supports the belief that Viking sailors used solar compasses to navigate and may have passed on this knowledge to other populations in Europe.The appraisal of the eight stone disks was featured in a December 2024 paper published in Sprawozdania Archeologiczne, a Polish archeological journal. The studys authors contend that some of the disks display key features that would have used the sun to operate as a compass, sharing similarities with other Viking artifacts originating from Greenland and Poland.Identifying the Medieval DisksThe disks, found in several medieval-era archaeological sites in Ukraine, were originally crafted from pyrophyllite, a soft and easy-to-process mineral used for many industrial purposes during the period. The researchers concentrated on three of the disks that already had detailed descriptions: two from the northern Chernihiv region (referred to as Listven and Liubech) and one from nearby Kyiv. The disks were dated from the 12th and 13th centuries, and they were most likely local products made in workshops near the city of Ovruch.Previous interpretations of these objects have ranged from calendars to needle-sharpening devices, but the new study proposes that they were instead used as navigational tools.One reason for this is the disks design, with the Kyiv and Listven disks featuring a central hole that could hold the gnomon the pointy component of a sundial that casts a shadow when hit with sunlight. This would help determine latitude in the case of a compass. In addition, concentric rings and radial lines were carved into the three disks, further demonstrating the semblance of a compass.Similarities Among Viking Solar CompassesThe researchers compared the pyrophyllite disks with other artifacts that have been identified as navigational instruments used by Vikings. Of particular importance are wooden disks, including one from Greenland found in 1948 and one from the Polish island of Wolin found in 2000. These wooden disks contained elements characteristic of sundial-compasses, such as a hole for a gnomon and perimeter notches.The wooden disks and the pyrophyllite disks share several features, including certain markings. The Wolin disk, dated to the end of the first half of the 11th century, has concentric rings similar to the pyrophyllite disks. However, the Greenland disk, dated to around the start of the 11th century, does not have concentric rings. The researchers suggest that this could mean concentric rings were not present in early Viking solar compasses, but developed in later versions.All of the disks were also similar sizes the Greenland and Wolin disks were measured at 7 cm and 8.6 cm in diameter respectively; the Kyiv and Listven disks were both 6.5 cm in diameter, while the Liubech disk measured 7.5 cm.Although additional investigations are needed to confirm the role of the pyrophyllite disks, the researchers say it is possible that Vikings who traveled through what is now Russia and Ukraine during medieval times (known as Varangians) could have imparted technological knowledge that allowed locals to create the solar compasses. Varangian travelers would have passed by Kyiv, Listven, and Liubech on their journeys along a major trade route connecting Scandinavia with the Eastern Roman Empire, making the spread of Viking-inspired solar compass technology in the region a real possibility.The Fabled Power of Sun StonesPrevious studies have theorized that Vikings relied heavily on the sun to navigate when sailing and used solar compasses to reach their destinations. The skies needed to be clear for these compasses to reliably work, yet the Vikings may have had a workaround for when the clouds rolled in.Sounding like something straight out of a fantasy novel, old Norse sagas speak of sun stones that could locate the hidden sun when held up to the overcast sky. A sun stone (possibly calcite or cordierite) would have theoretically acted as a sort of filter that determined the direction of polarized light from the sun, which is scattered in the air as it passes through the atmosphere.No concrete evidence of the stones has been found, but scientists have shown that it could have been a viable way of navigating. One 2018 study that conducted computer simulations of Viking voyages from Norway to Greenland using sun stones showed that sky polarization yielded successful navigation rates, even on cloudy days.The Vikings navigation methods arent fully understood, but most signs point toward their use of the sun. Harnessing solar compasses and maybe even sun stones they made it all the way to places like Greenland and Newfoundland, leaving behind bewildering remnants of their culture.
