  • It's absolutely infuriating to see how companies like Acer continue to shove their so-called "cutting-edge technology" down our throats while the actual issues in the tech world remain unaddressed. Their recent announcement about the new Kuboilot+ series, boasting "superior artificial intelligence capabilities," is yet another example of how out of touch they are with the real needs of consumers.

    Let’s break it down. What exactly are people looking for in a laptop today? Is it just flashy features and buzzwords like "AI"? Or is it more about reliability, usability, and actual performance? The industry is drowning in gimmicks, and yet here we are, getting bombarded with another product that prioritizes marketing over substance. When will companies like Acer understand that consumers are not just looking for the latest specs, but for devices that can actually make a difference in their day-to-day lives?

    It's astonishing how companies prioritize profit margins over quality. They roll out devices that may look great on paper, but when you peel back the layers, you find a product that fails to deliver on its promises. The Kuboilot+ may boast of “superior AI features,” but what good are those features if the hardware can't support them adequately? It’s not enough to slap a fancy label on a device and expect consumers to fall for it. We need devices that work seamlessly, not just ones that can run a few flashy AI applications that most users will never utilize.

    Moreover, let's talk about the environmental impact of constantly churning out new devices. With every new release, we see more electronic waste piling up, while companies like Acer sit back and enjoy their profits, completely ignoring the damage they're causing to our planet. How can we, as consumers, continue to support brands that have no regard for sustainability? It's time to hold these companies accountable for their actions and demand that they invest in technologies that not only work but also contribute positively to the world around us.

    And let's not forget about customer support. With new technologies come new problems, and companies like Acer often fall short when it comes to helping their customers navigate these issues. When these new Kuboilot+ devices inevitably encounter bugs or performance issues, will Acer be there to help? Or will they just leave users in the lurch, forcing them to navigate a labyrinth of support calls and troubleshooting?

    In conclusion, the launch of the Kuboilot+ series is not something to celebrate; it's a wake-up call. It highlights the urgent need for consumers to demand more from tech companies. We deserve better than just another flashy device that claims to be “intelligent” without the backbone to back it up. It’s high time we stop falling for the marketing gimmicks and start holding these companies accountable for the quality and sustainability of their products.

  • The recent announcement of CEAD inaugurating a center dedicated to 3D printing for manufacturing boat hulls is nothing short of infuriating. We are living in an age where technological advancements should lead to significant improvements in efficiency and sustainability, yet here we are, celebrating a move that reeks of superficial progress and misguided priorities.

    First off, let’s talk about the so-called “Maritime Application Center” (MAC) in Delft. While they dazzle us with their fancy new facility, one has to question the real implications of such a center. Are they genuinely solving the pressing issues of the maritime industry, or are they merely jumping on the bandwagon of 3D printing hype? The idea of using large-scale additive manufacturing to produce boat hulls sounds revolutionary, but let’s face it: this is just another example of throwing technology at a problem without truly understanding the underlying challenges that plague the industry.

    The maritime sector is facing severe environmental concerns, including pollution from traditional manufacturing processes and shipping practices. Instead of addressing these burning issues head-on, CEAD and others like them seem content to play with shiny new tools. 3D printing, in theory, could reduce waste—a point they love to hammer home in their marketing. But what about the energy consumption and material sourcing involved? Are we simply swapping one form of environmental degradation for another?

    Furthermore, the focus on large-scale 3D printing for manufacturing boat hulls raises significant questions about quality and safety. The maritime industry is not a playground for experimental technologies; lives are at stake. Relying on printed components that could potentially have structural weaknesses is a reckless gamble, and the consequences could be disastrous. Are we prepared to accept the liability if these hulls fail at sea?

    Let’s not forget the economic implications of this move. Sure, CEAD is likely patting themselves on the back for creating jobs at the MAC, but how many traditional jobs are they putting at risk? The maritime industry relies on skilled labor and craftsmanship that cannot simply be replaced by a machine. By pushing for 3D printing at such a scale, they threaten the livelihoods of countless workers who have dedicated their lives to mastering this trade.

    In conclusion, while CEAD’s center for 3D printing boat hulls may sound impressive on paper, the reality is that it’s a misguided effort that overlooks critical aspects of sustainability, safety, and social responsibility. We need to demand more from our industries and hold them accountable for their actions instead of blindly celebrating every shiny new innovation. The maritime industry deserves solutions that genuinely address its challenges rather than a mere technological gimmick.

  • Casa Sofia by Mário Martins Atelier: A Contemporary Urban Infill in Lagos

    Casa Sofia | © Fernando Guerra / FG+SG
    Located in the historic heart of Lagos, Portugal, Casa Sofia by Mário Martins Atelier is a thoughtful exercise in urban integration and contemporary reinterpretation. Occupying a site once held by a modest two-story house, the project is situated on the corner of a block facing the Church of St Sebastião. With its commanding presence, this national monument set a formidable challenge for the architects: introducing a new residence that respects the weight of history while offering a clear, contemporary expression.

    It is therefore important to design a building to fit into and complete the block. A house that is quiet and solid, with rhythmic metrics, whose new design brings an identity, with the weight and scent of the times, to a city that has existed for many centuries.

    Spatial Organization and Circulation
    The design’s ambition is anchored in reconciling modern residential needs with the dense urban fabric that defines the walled city. Rather than imposing a bold or disruptive form, the project embraces the existing rhythms and textures of the surrounding architecture. The result is a building that both defers to and elevates the neighborhood’s character. Its restrained profile and carefully modulated facade echo the massing and articulation of the original house while introducing an identity that is clearly of its time.
    At the core of Casa Sofia’s spatial organization is a deliberate hierarchy of spaces that transitions seamlessly between public, semi-public, and private domains. Entry from the street occurs through a modest set of steps leading to an exterior atrium. This threshold mediates the relationship between the public realm and the interior, grounding the house in its urban context. Once inside, an open hall reveals the vertical flow of the building, dominated by a staircase that appears to float, linking the house’s various levels while maintaining visual continuity throughout.
    The ground floor houses three bedrooms, each with an ensuite bathroom, radiating from the central hall. This level also contains a small basement for technical support, reinforcing the discreet layering of functional and domestic spaces. Midway up the staircase, the house opens onto a garage, a laundry room, and an intimate courtyard. These areas, essential for daily life, are seamlessly integrated into the overall composition, contributing to a spatial richness that is both pragmatic and sensorial.
    On the first floor, an open-plan arrangement accommodates the main living spaces. Around a central void, the living and dining areas, kitchen, and master suite are arranged to encourage visual interplay and shared light. This configuration enhances the spatial porosity, ensuring that despite the density of the historic center, the house retains a sense of openness and fluidity. Above, a recessed roof level recedes from the street, culminating in a panoramic terrace with a swimming pool. Here, the building dissolves into the sky, offering expansive views and light-filled leisure spaces that contrast with the more enclosed lower floors.
    Materiality and Craftsmanship
    Materiality plays a decisive role in mediating the building’s relationship with its context. White-painted plaster, a familiar element in the region, is punctuated by deep limestone moldings. These details create a play of light and shadow that emphasizes the facade’s verticality and rhythm. The generous thickness of the walls, carried over from the site’s earlier construction, lends a sense of solidity and permanence to the house, recalling the tactile traditions of the Algarve’s architecture.
    The interior and exterior detailing is characterized by an economy of means, where each material is selected for its ability to reinforce the house’s quiet presence. Local materials and craftsmanship ground the project in its immediate context while responding to environmental imperatives. High thermal comfort is achieved through careful orientation and passive design strategies, complemented by the integration of solar control and water conservation measures. These considerations underscore the project’s commitment to sustainability without resorting to superficial gestures.
    Broader Urban and Cultural Implications
    Beyond its immediate function as a family home, Casa Sofia engages in a broader dialogue with its urban and cultural surroundings. The project exemplifies a measured response to the question of how to build within a historical setting without resorting to nostalgia or pastiche. It demonstrates that contemporary architecture can find resonance within heritage contexts by prioritizing the values of continuity, scale, and material authenticity.
    In its measured dialogue with the Church of St Sebastião and the centuries-old urban landscape of Lagos, Casa Sofia illustrates the potential for architecture to enrich the experience of place through quiet, rigorous interventions. It is a project that reaffirms architecture’s capacity to negotiate between past and present, crafting spaces that are at once deeply contextual and unambiguously of their moment.

The project exemplifies a measured response to the question of how to build within a historical setting without resorting to nostalgia or pastiche. It demonstrates that contemporary architecture can find resonance within heritage contexts by prioritizing the values of continuity, scale, and material authenticity. In its measured dialogue with the Church of St Sebastião and the centuries-old urban landscape of Lagos, Casa Sofia illustrates the potential for architecture to enrich the experience of place through quiet, rigorous interventions. It is a project that reaffirms architecture’s capacity to negotiate between past and present, crafting spaces that are at once deeply contextual and unambiguously of their moment.

  • Government ditches public sector decarbonisation scheme

    The government has axed a scheme for upgrading energy efficiency in public sector buildings.
    The Public Sector Decarbonisation Schemedelivered more than £2.5bn in its first three phases for measures such as heat pumps, solar panels, insulation and double glazing, with further funding of nearly £1bn recently announced.
    But the Department for Energy Security and Net Zerohas told Building Design that the scheme has been dropped after the spending review, leaving uncertainty about how upgrades will be funded when the current phase expires in 2028.

    The department said it would set out plans for the period after 2028 in due course.
    In a post on LinkedIn, Dave Welkin, director of sustainability at Gleeds, said he had waited for the release of the spending review with a “sense of trepidation” and was unable to find mention of public sector decarbonisation when Treasury documents were released.
    “I hoped because it was already committed in the Budget that its omission wasn’t ominous,” he wrote.
    Yesterday, he was told by Salix Finance, the non-departmental public body that delivers funding for the scheme, that it was no longer being funded.
    It comes after the withdrawal of funding for the Low Carbon Skills Fundin May.
    According to the government’s website, PSDS and LCSF were intended to support the reduction of emissions from public sector buildings by 75% by 2037, compared to a 2017 baseline.
    “Neither LCSF or PSDS were perfect by any means, but they did provide a vital source of funding for local authorities, hospitals, schools and many other public sector organisations to save energy, carbon and money,” Welkin said.
    “PSDS has helped replace failed heating systems in schools, keeping students warm. It’s replaced roofs on hospitals, helping patients recover from illness. It’s replaced windows in our prisons, improving security and stopping drugs getting behind bars.”
    However, responding to Welkin’s post, Steve Connolly, chief executive at Arriba Technologies, a low carbon heating and cooling firm, said that the scheme was being “mismanaged” with a small number of professional services firms “scooping up disproportionately large grants for their clients”.
    The fourth phase of the scheme was confirmed last September, with allocations confirmed only last month.
    This latest phase, which covers the financial years between 2025/26 and 2027/28, saw the distribution of £940m across the country.
    A DESNZ spokesperson said: “Our settlement is about investing in Britain’s renewal to create energy security, sprint to clean power by 2030, encourage investment, create jobs and bring down bills for good.
    “We will deliver £1bn in current allocations of the Public Sector Decarbonisation Scheme until 2028 and, through Great British Energy, have invested in new rooftop solar power and renewable schemes to lower energy bills for schools and hospitals across the UK.
    “We want to build on this progress by incentivising the public sector to decarbonise, so they can reap the benefits in lower bills and emissions, sharing best practice across government and exploring the use of repayable finance, where appropriate.”
    A government assessment of phase 3a and 3b projects identified a number of issues with the scheme, including delays and cost inflation, with more than a tenth being abandoned subsequent to grants being offered.
    Stakeholders interviewed for the report also identified “difficulties in obtaining skilled contractors and equipment”, especially air source heat pumps.
    The first come first served approach to awarding funding was also said to be “encouraging applicants to opt for more straightforward projects” and “potentially undermining the achievement of PSDS objective by restricting the opportunity for largermore complex measures which may have delivered greater carbon reduction benefits”.
    But the consensus among stakeholders and industry representatives interviewed for the report was that the scheme was “currently key to sustaining the existing UK heat pump market” and that it was “seen as vital in enabling many public sector organisations to invest in heat decarbonisation”.

  • NOSIPHO MAKETO-VAN DEN BRAGT ALTERED HER CAREER PATH TO LAUNCH CHOCOLATE TRIBE

    By TREVOR HOGG

    After initially pursuing a career as an attorney, Nosipho Maketo-van den Bragt discovered her true calling was to apply her legal knowledge in a more artistic endeavor with her husband, Rob Van den Bragt, who had forged a career as a visual effects supervisor. The couple co-founded Chocolate Tribe, the Johannesburg and Cape Town-based visual effects and animation studio that has done work for Netflix, BBC, Disney and Voltage Pictures.

    “It was following my passion and my passion finding me,” observes Maketo-van den Bragt, Owner and CEO of Chocolate Tribe and Founder of AVIJOZI. “I grew up in Soweto, South Africa, and we had this old-fashioned television. I was always fascinated by how those people got in there to perform and entertain us. Living in the townships, you become the funnel for your parents’ aspirations and dreams. My dad was a judge’s registrar, so he was writing all of the court cases coming up for a judge. My dad would come home and tell us stories of what happened in court. I found this enthralling, funny and sometimes painful because it was about people’s lives. I did law and to some extent still practice it. My legal career and entertainment media careers merged because I fell in love with the storytelling aspect of it all. There are those who say that lawyers are failed actors!”

    Chocolate Tribe hosts what has become the annual AVIJOZI festival with Netflix. AVIJOZI is a two-day, free-access event in Johannesburg focused on Animation/Film, Visual Effects and Interactive Technology. This year’s AVIJOZI is scheduled for September 13-14 in Johannesburg.

    A personal ambition was to find a way to merge married life into a professional partnership. “I never thought that a lawyer and a creative would work together,” admits Maketo-van den Bragt. “However, Rob and I had this great love for watching films together and music; entertainment was the core fabric of our relationship. That was my first gentle schooling into the visual effects and animation content development space. Starting the company was due to both of us being out of work. I had quit my job without any sort of plan B. I actually incorporated Chocolate Tribe as a company without knowing what we would do with it. As time went on, there was a project that we were asked to come to do. The relationship didn’t work out, so Rob and I decided, ‘Okay, it seems like we can do this on our own.’ I’ve read many books about visual effects and animation, and I still do. I attend a lot of festivals. I am connected with a lot of the guys who work in different visual effects spaces because it is all about understanding how it works and, from a business side, how can we leverage all of that information?”

    Chocolate Tribe provided VFX and post-production for Checkers supermarket’s “Planet” ad promoting environmental sustainability. The Chocolate Tribe team pushed photorealism for the ad, creating three fully CG creatures: a polar bear, orangutan and sea turtle.

    With a population of 1.5 billion, there is no shortage of consumers and content creators in Africa. “Nollywood is great because it shows us that even with minimal resources, you can create a whole movement and ecosystem,” Maketo-van den Bragt remarks. “Maybe the question around Nollywood is making sure that the caliber and quality of work is high end and speaks to a global audience. South Africa has the same dynamics. It’s a vibrant traditional film and animation industry that grows in leaps and bounds every year. More and more animation houses are being incorporated or started with CEOs or managing directors in their 20s. There’s also an eagerness to look for different stories which haven’t been told. Africa gives that opportunity to tell stories that ordinary people, for example, in America, have not heard or don’t know about. There’s a huge rise in animation, visual effects and content in general.”

    Rob van den Bragt served as Creative Supervisor and Nosipho Maketo-van den Bragt as Studio Executive for the “Surf Sangoma” episode of the Disney+ series Kizazi Moto: Generation Fire.

    Film tax credits have contributed to The Woman King, Dredd, Safe House, Black Sails and Mission: Impossible – Final Reckoning shooting in South Africa. “People understand principal photography, but there is confusion about animation and visual effects,” Maketo-van den Bragt states. “Rebates pose a challenge because now you have to go above and beyond to explain what you are selling. It’s taken time for the government to realize this is a viable career.” The streamers have had a positive impact. “For the most part, Netflix localizes, and that’s been quite a big hit because it speaks to the demographics and local representation and uplifts talent within those geographical spaces. We did one of the shorts for Disney’s Kizazi Moto: Generation Fire, and there was huge global excitement to that kind of anthology coming from Africa. We’ve worked on a number of collaborations with the U.K., and often that melding of different partners creates a fusion of universality. We need to tell authentic stories, and that authenticity will be dictated by the voices in the writing room.”

    AVIJOZI was established to support the development of local talent in animation, visual effects, film production and gaming. “AVIJOZI stands for Animation Visual Effects Interactive in JOZI,” Maketo-van den Bragt explains. “It is a conference as well as a festival. The conference part is where we have networking sessions, panel discussions and behind-the-scenes presentations to draw the curtain back and show what happens when people create avatars. We want to show the next generation that there is a way to do this magical craft. The festival part is people have film screenings and music as well. We’ve brought in gaming as an integral aspect, which attracts many young people because that’s something they do at an early age. Gaming has become the common sport. AVIJOVI is in its fourth year now. It started when I got irritated by people constantly complaining, ‘Nothing ever happens in Johannesburg in terms of animation and visual effects.’ Nobody wanted to do it. So, I said, ‘I’ll do it.’ I didn’t know what I was getting myself into, and four years later I have lots of gray hair!”

    Rob van den Bragt served as Animation Supervisor/Visual Effects Supervisor and Nosipho Maketo-van den Bragt as an Executive Producer on iNumber Number: Jozi Goldfor Netflix.Mentorship and internship programs have been established with various academic institutions, and while there are times when specific skills are being sought, like rigging, the field of view tends to be much wider. “What we are finding is that the people who have done other disciplines are much more vibrant,” Maketo-van den Bragt states. “Artists don’t always know how to communicate because it’s all in their heads. Sometimes, somebody with a different background can articulate that vision a bit better because they have those other skills. We also find with those who have gone to art school that the range within their artistry and craftsmanship has become a ‘thing.’ When you have mentally traveled where you have done other things, it allows you to be a more well-rounded artist because you can pull references from different walks of life and engage with different topics without being constrained to one thing. We look for people with a plethora of skills and diverse backgrounds. It’s a lot richer as a Chocolate Tribe. There are multiple flavors.”

    There is a particular driving force when it comes to mentoring. “I want to be the mentor I hoped for,” Maketo-van den Bragt remarks. “I have silent mentors in that we didn’t formalize the relationship, but I knew they were my mentors because every time I would encounter an issue, I would be able to call them. One of the people who not only mentored but pushed me into different spaces is Jinko Gotoh, who is part of Women in Animation. She brought me into Women in Animation, and I had never mentored anybody. Here I was, sitting with six women who wanted to know how I was able to build up Chocolate Tribe. I didn’t know how to structure a presentation to tell them about the journey because I had been so focused on the journey. It’s a sense of grit and feeling that I cannot fail because I have a whole community that believes in me. Even when I felt my shoulders sagging, they would be there to say, ‘We need this. Keep it moving.’ This isn’t just about me. I have a whole stream of people who want this to work.”

    Numerous unknown factors had to be accounted for, which made predicting how the journey would unfold extremely difficult. “What it looks like and what I expected it to be, you don’t have the full sense of what it would lead to in this situation,” Maketo-van den Bragt states. “I can tell you that there have been moments of absolute joy where I was so excited we got this project or won that award. There are other moments where you feel completely lost and ask yourself, ‘Am I doing the right thing?’ The journey is to have the highs, lows and moments of confusion. I go through it and accept that not every day will be an award-winning day. For the most part, I love this journey. I wanted to be somewhere where there was a purpose. What has been a big highlight is when I’m signing a contract for new employees who are excited about being part of Chocolate Tribe. Also, when you get a new project and it’s exciting, especially from a service or visual effects perspective, we’re constantly looking for that dragon or big creature. It’s about being mesmerizing, epic and awesome.”

    Maketo-van den Bragt has two major career-defining ambitions. “Fostering the next generation of talent and making sure that they are ready to create these amazing stories properly – that is my life work, and relating the African narrative to let the world see the human aspect of who we are because for the longest time we’ve been written out of the stories and narratives.”

There are other moments where you feel completely lost and ask yourself, ‘Am I doing the right thing?’ The journey is to have the highs, lows and moments of confusion.

    NOSIPHO MAKETO-VAN DEN BRAGT ALTERED HER CAREER PATH TO LAUNCH CHOCOLATE TRIBE
    By TREVOR HOGG Images courtesy of Chocolate Tribe. Nosipho Maketo-van den Bragt, Owner and CEO, Chocolate Tribe After initially pursuing a career as an attorney, Nosipho Maketo-van den Bragt discovered her true calling was to apply her legal knowledge in a more artistic endeavor with her husband, Rob Van den Bragt, who had forged a career as a visual effects supervisor. The couple co-founded Chocolate Tribe, the Johannesburg and Cape Town-based visual effects and animation studio that has done work for Netflix, BBC, Disney and Voltage Pictures. “It was following my passion and my passion finding me,” observes Maketo-van den Bragt, Owner and CEO of Chocolate Tribe and Founder of AVIJOZI. “I grew up in Soweto, South Africa, and we had this old-fashioned television. I was always fascinated by how those people got in there to perform and entertain us. Living in the townships, you become the funnel for your parents’ aspirations and dreams. My dad was a judge’s registrar, so he was writing all of the court cases coming up for a judge. My dad would come home and tell us stories of what happened in court. I found this enthralling, funny and sometimes painful because it was about people’s lives. I did law and to some extent still practice it. My legal career and entertainment media careers merged because I fell in love with the storytelling aspect of it all. There are those who say that lawyers are failed actors!” Chocolate Tribe hosts what has become the annual AVIJOZI festival with Netflix. AVIJOZI is a two-day, free-access event in Johannesburg focused on Animation/Film, Visual Effects and Interactive Technology. This year’s AVIJOZI is scheduled for September 13-14 in Johannesburg.

A personal ambition was to find a way to merge married life into a professional partnership. “I never thought that a lawyer and a creative would work together,” admits Maketo-van den Bragt. “However, Rob and I had this great love for watching films together and music; entertainment was the core fabric of our relationship. That was my first gentle schooling into the visual effects and animation content development space. Starting the company was due to both of us being out of work. I had quit my job without any sort of plan B. I actually incorporated Chocolate Tribe as a company without knowing what we would do with it. As time went on, there was a project that we were asked to come to do. The relationship didn’t work out, so Rob and I decided, ‘Okay, it seems like we can do this on our own.’ I’ve read many books about visual effects and animation, and I still do. I attend a lot of festivals. I am connected with a lot of the guys who work in different visual effects spaces because it is all about understanding how it works and, from a business side, how can we leverage all of that information?” Chocolate Tribe provided VFX and post-production for Checkers supermarket’s “Planet” ad promoting environmental sustainability. The Chocolate Tribe team pushed photorealism for the ad, creating three fully CG creatures: a polar bear, orangutan and sea turtle. With a population of 1.5 billion, there is no shortage of consumers and content creators in Africa. “Nollywood is great because it shows us that even with minimal resources, you can create a whole movement and ecosystem,” Maketo-van den Bragt remarks. “Maybe the question around Nollywood is making sure that the caliber and quality of work is high end and speaks to a global audience. South Africa has the same dynamics. It’s a vibrant traditional film and animation industry that grows in leaps and bounds every year. More and more animation houses are being incorporated or started with CEOs or managing directors in their 20s. There’s also an eagerness to look for different stories which haven’t been told. Africa gives that opportunity to tell stories that ordinary people, for example, in America, have not heard or don’t know about. There’s a huge rise in animation, visual effects and content in general.” Rob van den Bragt served as Creative Supervisor and Nosipho Maketo-van den Bragt as Studio Executive for the “Surf Sangoma” episode of the Disney+ series Kizazi Moto: Generation Fire.

Family photo of the Maketos. Maketo-van de Bragt has two siblings. Film tax credits have contributed to The Woman King, Dredd, Safe House, Black Sails and Mission: Impossible – Final Reckoning shooting in South Africa. “People understand principal photography, but there is confusion about animation and visual effects,” Maketo-van den Bragt states. “Rebates pose a challenge because now you have to go above and beyond to explain what you are selling. It’s taken time for the government to realize this is a viable career.” The streamers have had a positive impact. “For the most part, Netflix localizes, and that’s been quite a big hit because it speaks to the demographics and local representation and uplifts talent within those geographical spaces. We did one of the shorts for Disney’s Kizazi Moto: Generation Fire, and there was huge global excitement to that kind of anthology coming from Africa. We’ve worked on a number of collaborations with the U.K., and often that melding of different partners creates a fusion of universality. We need to tell authentic stories, and that authenticity will be dictated by the voices in the writing room.” AVIJOZI was established to support the development of local talent in animation, visual effects, film production and gaming. “AVIJOZI stands for Animation Visual Effects Interactive in JOZI [nickname for Johannesburg],” Maketo-van den Bragt explains. “It is a conference as well as a festival. The conference part is where we have networking sessions, panel discussions and behind-the-scenes presentations to draw the curtain back and show what happens when people create avatars. We want to show the next generation that there is a way to do this magical craft. The festival part is people have film screenings and music as well. We’ve brought in gaming as an integral aspect, which attracts many young people because that’s something they do at an early age. Gaming has become the common sport. AVIJOVI is in its fourth year now. It started when I got irritated by people constantly complaining, ‘Nothing ever happens in Johannesburg in terms of animation and visual effects.’ Nobody wanted to do it. So, I said, ‘I’ll do it.’ I didn’t know what I was getting myself into, and four years later I have lots of gray hair!” Rob van den Bragt served as Animation Supervisor/Visual Effects Supervisor and Nosipho Maketo-van den Bragt as an Executive Producer on iNumber Number: Jozi Gold (2023) for Netflix. (Image courtesy of Chocolate Tribe and Netflix) Mentorship and internship programs have been established with various academic institutions, and while there are times when specific skills are being sought, like rigging, the field of view tends to be much wider. “What we are finding is that the people who have done other disciplines are much more vibrant,” Maketo-van den Bragt states. “Artists don’t always know how to communicate because it’s all in their heads. Sometimes, somebody with a different background can articulate that vision a bit better because they have those other skills. We also find with those who have gone to art school that the range within their artistry and craftsmanship has become a ‘thing.’ When you have mentally traveled where you have done other things, it allows you to be a more well-rounded artist because you can pull references from different walks of life and engage with different topics without being constrained to one thing. We look for people with a plethora of skills and diverse backgrounds. It’s a lot richer as a Chocolate Tribe. There are multiple flavors.” South African director/producer/cinematographer and drone cinemtography specialist FC Hamman, Founder of FC Hamman Films, at AVIJOZI 2024. There is a particular driving force when it comes to mentoring. “I want to be the mentor I hoped for,” Maketo-van den Bragt remarks. “I have silent mentors in that we didn’t formalize the relationship, but I knew they were my mentors because every time I would encounter an issue, I would be able to call them. One of the people who not only mentored but pushed me into different spaces is Jinko Gotoh, who is part of Women in Animation. She brought me into Women in Animation, and I had never mentored anybody. Here I was, sitting with six women who wanted to know how I was able to build up Chocolate Tribe. I didn’t know how to structure a presentation to tell them about the journey because I had been so focused on the journey. It’s a sense of grit and feeling that I cannot fail because I have a whole community that believes in me. Even when I felt my shoulders sagging, they would be there to say, ‘We need this. Keep it moving.’ This isn’t just about me. I have a whole stream of people who want this to work.” Netflix VFX Manager Ben Perry, who oversees Netflix’s VFX strategy across Africa, the Middle East and Europe, at AVIJOZI 2024. Netflix was a partner in AVIJOZI with Chocolate Tribe for three years.

  • Rewriting SymCrypt in Rust to modernize Microsoft’s cryptographic library 

    Outdated coding practices and memory-unsafe languages like C are putting software, including cryptographic libraries, at risk. Fortunately, memory-safe languages like Rust, along with formal verification tools, are now mature enough to be used at scale, helping prevent issues like crashes, data corruption, flawed implementation, and side-channel attacks.
    To address these vulnerabilities and improve memory safety, we’re rewriting SymCrypt—Microsoft’s open-source cryptographic library—in Rust. We’re also incorporating formal verification methods. SymCrypt is used in Windows, Azure Linux, Xbox, and other platforms.
    Currently, SymCrypt is primarily written in cross-platform C, with limited use of hardware-specific optimizations through intrinsicsand assembly language. It provides a wide range of algorithms, including AES-GCM, SHA, ECDSA, and the more recent post-quantum algorithms ML-KEM and ML-DSA. 
    Formal verification will confirm that implementations behave as intended and don’t deviate from algorithm specifications, critical for preventing attacks. We’ll also analyze compiled code to detect side-channel leaks caused by timing or hardware-level behavior.
    Proving Rust program properties with Aeneas
    Program verification is the process of proving that a piece of code will always satisfy a given property, no matter the input. Rust’s type system profoundly improves the prospects for program verification by providing strong ownership guarantees, by construction, using a discipline known as “aliasing xor mutability”.
    For example, reasoning about C code often requires proving that two non-const pointers are live and non-overlapping, a property that can depend on external client code. In contrast, Rust’s type system guarantees this property for any two mutably borrowed references.
    As a result, new tools have emerged specifically for verifying Rust code. We chose Aeneasbecause it helps provide a clean separation between code and proofs.
    Developed by Microsoft Azure Research in partnership with Inria, the French National Institute for Research in Digital Science and Technology, Aeneas connects to proof assistants like Lean, allowing us to draw on a large body of mathematical proofs—especially valuable given the mathematical nature of cryptographic algorithms—and benefit from Lean’s active user community.
    Compiling Rust to C supports backward compatibility  
    We recognize that switching to Rust isn’t feasible for all use cases, so we’ll continue to support, extend, and certify C-based APIs as long as users need them. Users won’t see any changes, as Rust runs underneath the existing C APIs.
    Some users compile our C code directly and may rely on specific toolchains or compiler features that complicate the adoption of Rust code. To address this, we will use Eurydice, a Rust-to-C compiler developed by Microsoft Azure Research, to replace handwritten C code with C generated from formally verified Rust. Eurydicecompiles directly from Rust’s MIR intermediate language, and the resulting C code will be checked into the SymCrypt repository alongside the original Rust source code.
    As more users adopt Rust, we’ll continue supporting this compilation path for those who build SymCrypt from source code but aren’t ready to use the Rust compiler. In the long term, we hope to transition users to either use precompiled SymCrypt binaries, or compile from source code in Rust, at which point the Rust-to-C compilation path will no longer be needed.

    Timing analysis with Revizor 
    Even software that has been verified for functional correctness can remain vulnerable to low-level security threats, such as side channels caused by timing leaks or speculative execution. These threats operate at the hardware level and can leak private information, such as memory load addresses, branch targets, or division operands, even when the source code is provably correct. 
    To address this, we’re extending Revizor, a tool developed by Microsoft Azure Research, to more effectively analyze SymCrypt binaries. Revizor models microarchitectural leakage and uses fuzzing techniques to systematically uncover instructions that may expose private information through known hardware-level effects.  
    Earlier cryptographic libraries relied on constant-time programming to avoid operations on secret data. However, recent research has shown that this alone is insufficient with today’s CPUs, where every new optimization may open a new side channel. 
    By analyzing binary code for specific compilers and platforms, our extended Revizor tool enables deeper scrutiny of vulnerabilities that aren’t visible in the source code.
    Verified Rust implementations begin with ML-KEM
    This long-term effort is in alignment with the Microsoft Secure Future Initiative and brings together experts across Microsoft, building on decades of Microsoft Research investment in program verification and security tooling.
    A preliminary version of ML-KEM in Rust is now available on the preview feature/verifiedcryptobranch of the SymCrypt repository. We encourage users to try the Rust build and share feedback. Looking ahead, we plan to support direct use of the same cryptographic library in Rust without requiring C bindings. 
    Over the coming months, we plan to rewrite, verify, and ship several algorithms in Rust as part of SymCrypt. As our investment in Rust deepens, we expect to gain new insights into how to best leverage the language for high-assurance cryptographic implementations with low-level optimizations. 
    As performance is key to scalability and sustainability, we’re holding new implementations to a high bar using our benchmarking tools to match or exceed existing systems.
    Looking forward 
    This is a pivotal moment for high-assurance software. Microsoft’s investment in Rust and formal verification presents a rare opportunity to advance one of our key libraries. We’re excited to scale this work and ultimately deliver an industrial-grade, Rust-based, FIPS-certified cryptographic library.
