Summary of DNS-PERSIST-01: A New Model for DNS-based Challenge Validation

A new validation method for certificate requests, called DNS-PERSIST-01, is being introduced by Let's Encrypt. This method simplifies the process of proving ownership of domain names for certificate issuance, particularly for wildcard certificates or in situations where exposing infrastructure online is risky.

Key Points:

• Current Method (DNS-01): Involves publishing a temporary token in DNS for each certificate request, which can lead to operational challenges like frequent DNS updates and security risks from sharing DNS credentials.
• New Method (DNS-PERSIST-01): Instead of needing a new token for each request, it allows users to create a permanent authorization record in DNS. This record identifies the certificate authority (CA) and the specific account authorized to issue certificates for that domain.
• Benefits:
  • Reduces the need for constant DNS changes and minimizes exposure of sensitive credentials.
  • Simplifies the renewal process since the same record can be reused.
• Security Considerations: While DNS write access is more controlled, protecting the account key becomes crucial as the authorization persists indefinitely.
• Additional Features: Users can specify if the authorization applies to wildcard certificates or set an expiration date for the authorization record.
• Implementation Timeline: The new specification was approved in late 2025, with support available now in testing software. A broader rollout is planned for early to mid-2026.

In summary, DNS-PERSIST-01 aims to enhance the efficiency and security of domain validation for certificate issuance, making it especially useful for environments with complex or sensitive setups.

The text discusses the need for terminals to create a 256-color palette based on a user's base16 theme. Base16 themes are popular for their simplicity, but they only allow for 16 colors, which limits complex applications. While truecolor supports 16 million colors, it comes with complications like needing separate theme configurations and slower performance.

The 256-color palette offers a middle ground, providing more colors than base16 without the complexities of truecolor. However, it has issues such as poor readability and clashes with base16 themes.

To solve these problems, the author suggests automatically generating the 256-color palette from the user's base16 colors. This would maintain ease of theming while providing a wider range of colors. The palette is structured into three parts: the base16 colors, a 216-color cube, and a grayscale ramp.

The document outlines the issues with the default 256-color palette, including inconsistent brightness and poor interpolation. It proposes using LAB color space for better brightness consistency. The text concludes that generating the 256-color palette from base16 themes would enhance usability and support across terminals, making it a practical choice for developers.

Le Minotaure est une créature mythique, mi-homme mi-taureau, qui vivait dans un labyrinthe en Crète. Selon la légende, il a été emprisonné par le roi Minos et se nourrissait de jeunes gens envoyés par Athènes en sacrifice. Ce rituel a duré jusqu'à ce qu'un héros athénien, Thésée, se porte volontaire pour le combattre. Avec l'aide d'Ariane, la fille de Minos, qui lui donna un fil pour retrouver son chemin, Thésée réussit à tuer le Minotaure et à s'échapper du labyrinthe.

L'histoire du Minotaure fascine depuis des milliers d'années et a inspiré de nombreuses œuvres artistiques. Des recherches archéologiques indiquent que cette légende est liée aux événements réels de la civilisation minoenne, qui a prospéré entre 3000 et 1100 avant J.-C. en Méditerranée. Les taureaux et les motifs de labyrinthe sont des symboles importants de cette culture.

Le mythe a évolué au fil du temps, avec diverses interprétations dans la littérature et l'art. Les récits classiques parlent souvent de l'importance des taureaux et du labyrinthe, et les artistes de différentes époques ont représenté le combat entre Thésée et le Minotaure, soulignant son impact culturel.

The author has developed two open-source protocols to manage AI agents more effectively, addressing the challenge of keeping them aligned with their intended behavior. The protocols are:

1. Agent Alignment Protocol (AAP): This defines what actions an agent is allowed to take.
2. Agent Integrity Protocol (AIP): This monitors what an agent is considering doing and ensures it aligns with AAP.

The main issue is that AI agents make decisions autonomously but lack a standard for declaring and verifying their allowed actions or detecting deviations. While observability tools show what actions occurred, these protocols ensure those actions were appropriate.

For example, if a customer support agent is asked to process a refund (an action it is not allowed to do), AIP will flag this potential violation before the agent acts, keeping it within its defined boundaries.

When multiple agents collaborate, they can share their alignment protocols to ensure their goals are compatible, preventing conflicts before they arise.

These protocols are available for free and can be integrated easily with existing AI systems. More information can be found on their GitHub page and documentation.

Summary: The Only Moat Left Is Money

On February 18, 2026, the author discusses the challenges of launching new products in an oversaturated market. Every day, many people create new apps or tools, but few get noticed. With the rise of AI, it’s become easier for anyone to create, which has led to a flood of options, making it harder for new products to gain attention.

The value of human creativity is decreasing, while the value of human attention is increasing. This shift means that simply doing more marketing isn’t enough, as traditional channels for reaching audiences have become less effective. Many successful creators now have an advantage due to their existing reach or financial resources.

The author expresses concern that newcomers without these advantages may struggle to succeed, as the market favors those who have already established a presence. They caution that if you act on the belief that the market is still accessible when it isn’t, you could waste time and money. Conversely, ignoring the reality of this situation could lead to permanent failure.

The author also mentions launching a new platform called Kith, a paid, invite-only social network that prioritizes genuine interactions without algorithms or ads. Interested individuals are encouraged to join the waitlist.

In 2026, JavaScript development tools are becoming faster and more efficient. The key updates include:

1. TypeScript Go (tsgo): A Go-based rewrite of TypeScript offers about 10 times faster type checking. It's being adopted widely and catches errors that the original version missed.

2. Oxfmt: This is a new formatter that combines features of Prettier and adds built-in plugins for better code formatting, making it a good alternative for developers.

3. Oxlint: A modern linter capable of using ESLint plugins directly. It offers type-aware linting and a strict configuration to improve code quality.

4. @nkzw/oxlint-config: A configuration package designed to enforce strict coding standards and reduce warnings, leading to cleaner and more reliable code.

5. Development Tools: The post mentions several tools:

   • npm-run-all2: A lightweight tool for running scripts in parallel without added complexities.
   • ts-node: For quickly running TypeScript during development, praised for its speed.
   • pnpm: The recommended package manager for its speed and features.
   • Vite: A preferred bundler and development server, known for its speed and stability.
   • React: Continues to be favored for UI development due to its performance and modern features.

Overall, these advancements aim to create a faster, more streamlined development experience without compromising on quality.

On February 17, 2026, it was reported that AVX2 code runs significantly slower than SSE2-4.x code when emulated on Windows ARM, specifically at about two-thirds the speed. This finding suggests that if performance is important, developers should not compile their apps for AVX2 if they might run on Windows ARM under emulation.

The author conducted benchmarks using a new math library to compare the performance of AVX2 against SSE2-4.x on both actual Intel hardware and ARM emulated environments. The benchmarks revealed that while native Intel hardware achieves a speed increase of 2.7 times with AVX2, the same code on ARM is slower than SSE2-4.x.

Key reasons for this performance gap include the differences in how ARM handles 128-bit NEON operations versus 256-bit AVX2 operations, potential optimizations in the emulation layer, and the specifics of the implementation in the emulator. The results emphasize that for software requiring heavy numerical computations, it is best to compile directly for ARM rather than relying on emulation for performance.

In conclusion, if performance is a priority, it is crucial to compile applications for ARM rather than depending on Windows ARM emulation of AVX2.

I am working on starting a Low Power FM radio station called KPBJ for the east San Fernando Valley in Los Angeles. Our future broadcast channel will be 95.9 FM. Currently, we have launched an internet stream featuring about 60 pre-recorded shows, mostly music with some talk shows. We allow anyone from the community to host a show without strict curation.

We have secured a location for our transmitter but need to raise funds for the necessary equipment and setup. The transmitter will operate at 100W power from a high elevation site, which will need an off-grid solar power system. Our goal is to connect the station to the transmitter wirelessly.

This project is a community-driven initiative managed by a non-profit organization. We are looking for support and donations to help make this radio station a reality. If you're interested in helping or hosting a show, please get in touch!

The author is exploring the idea of using 3D printing to encode a small amount of data onto a "disk." They believe that common 3D printer tools could potentially read this data. Although they think this concept might already exist, they are curious if anyone has implemented it or created a more advanced version with specialized equipment for reading and writing. They are particularly interested in using this method for long-term archival storage or securely storing encryption keys without digital copies. However, they suspect it may not be practical for these purposes and are looking for any information on the topic.

Microsoft has reported a bug in its Microsoft 365 Copilot that has been summarizing confidential emails since late January. This issue affects the Copilot chat feature, which is supposed to respect data protection rules. The bug allows Copilot to access and summarize emails from users' Sent Items and Drafts folders, even if those emails have confidentiality labels meant to protect sensitive information.

The problem was first noticed on January 21, and Microsoft has identified it as a code error that bypasses the safeguards in place. They have been working on a fix since early February and are monitoring its effectiveness. However, they have not disclosed how many users are affected or when the issue will be completely resolved.

In summary, a bug in Microsoft 365 Copilot is compromising email confidentiality, and Microsoft is actively addressing the issue.

Vincent Driessen recently expressed his disappointment after Microsoft used a diagram he created in 2010 for Git branching without giving him credit. His original diagram was designed with care and has been widely shared over the years. However, Microsoft seemingly altered it using AI, resulting in a poorly made version that lacked the quality and clarity of the original.

Driessen noted that while he appreciates the sharing of his work, he found it disheartening that Microsoft didn't respect the original creation process and instead produced a subpar imitation. He worries that as AI-generated content becomes more common, cases of plagiarism may become harder to recognize. He simply asks for proper attribution and is curious about how Microsoft's version came to be.

Ken Shirriff's blog discusses the Intel 8087 floating-point coprocessor chip, which was introduced in the 1980s to enhance the speed of IBM PCs, especially for applications like CAD and spreadsheets. The 8087 could perform basic arithmetic and complex mathematical functions, adding 62 new instructions to the computer.

Key points include:

1. Functionality: The 8087 performs calculations on 80-bit floating-point values and includes a constant ROM for important constants like π.

2. Instruction Decoding: Decoding instructions in the 8087 is complex, involving various circuits across the chip. It uses a microcode ROM to interpret and execute instructions.

3. Cooperation with the CPU: The 8087 works alongside the main 8086 or 8088 CPU. When a floating-point instruction arises, the CPU identifies it using ESCAPE opcodes, allowing the 8087 to execute it. The 8086 computes memory addresses for the 8087, which cannot access the CPU's registers directly.

4. Instruction Structure: The 8087 instructions consist of an ESCAPE opcode followed by a ModR/M byte that indicates how to access memory or registers. The design aimed to efficiently fit instructions within the available bits for straightforward decoding.

5. Microcode Execution: The chip has a microcode engine that processes instructions in low-level steps. It uses an 11-bit micro-address to manage the execution of these micro-instructions, including conditional jumps and subroutine calls.

Overall, the blog explores the intricate design and functionality of the 8087 chip, highlighting its role in enhancing computing performance during its time.

In 1987, economist Robert Solow noted a surprising trend: despite the introduction of new technologies like transistors and microprocessors, workplace productivity actually fell after 1973. This became known as Solow’s productivity paradox, as he remarked, "You can see the computer age everywhere but in the productivity statistics."

Today, a similar situation is occurring with AI. Although many companies report positive experiences with AI, a recent study shows that most executives see little impact on productivity or employment. About 66% of executives use AI, but only for about 1.5 hours a week, and 90% of firms report no significant effect from AI on their operations over the past three years.

Expectations for AI remain high, with executives predicting productivity increases of 1.4% in the next few years. However, recent research suggests mixed results regarding AI's actual impact on productivity, with some studies showing only modest gains.

Experts believe that, like past technological shifts, this pattern could change. While initial productivity growth may be slow, it could eventually rise significantly, similar to trends seen in the 1990s. The future success of AI in boosting productivity will depend on how effectively companies integrate and utilize the technology in their operations.

Meta CEO Mark Zuckerberg is testifying in a significant trial in Los Angeles about the impact of social media on children. This trial involves over 1,600 plaintiffs, including families and school districts, who claim platforms like Instagram, YouTube, TikTok, and Snap intentionally designed addictive features that harm young users' mental health.

Historically, social media companies have been protected from lawsuits due to a law that shields them from liability for user-generated content. However, this trial could change that. One plaintiff, a young woman named K.G.M., argues that her social media use as a minor led to addiction and worsened her mental health, alleging that companies prioritize profit over children's safety.

Zuckerberg's testimony is seen as a crucial moment for families seeking accountability. Matt Bergman, an attorney representing many plaintiffs, emphasized that this is the first time a Meta CEO will face a jury about the company's decisions regarding product safety. Parents have been actively involved, advocating for the truth about the risks of social media to their children.

In July 1954, J.R.R. Tolkien published The Lord of the Rings, revealing his deeply personal and imaginative world, which included a rich history and mythology. Tolkien's creation was heavily influenced by his invented languages, particularly two Elvish languages: Quenya and Sindarin. He believed that the development of these languages was foundational to his storytelling, stating that the stories were created to provide a context for the languages.

Tolkien expressed a desire to incorporate more of his languages into his work, but he edited much of it for the sake of reader accessibility. While there are names and some poetic forms in Elvish throughout The Lord of the Rings, actual conversational dialogue in these languages is scarce. Tolkien faced practical challenges; he wasn't fluent enough in his Elvish languages to write extensive narratives in them, and he often revised his linguistic concepts.

Tolkien's languages were meant for personal enjoyment and aesthetic expression, not as tools for conversational use. His linguistic inventions were fluid, changing over time, and he never aimed to create a fixed or complete language. As a result, the vocabulary and grammar of Quenya and Sindarin are incomplete and not suitable for everyday communication.

Despite this, interest in learning and using Elvish languages has emerged, particularly online, leading to the development of "Neo-Elvish" forms, which are modern adaptations of Tolkien's languages. These efforts reflect a desire to make Elvish more usable, even though Tolkien's original intent did not include creating languages for practical use.

The text discusses a new method for improving multi-view 3D reconstruction called Physically-Plausible ISP (PPISP). This method addresses issues caused by differences in camera characteristics and image processing, which often lead to poor results in novel views.

Key Points:

1. Problem: Current methods for correcting photometric inconsistencies are not effective for new viewpoints and lack a solid physical basis.

2. Solution: PPISP separates camera-specific issues from other image effects using physical transformations. It includes a controller that predicts image processing parameters for new views, similar to how real cameras adjust exposure and white balance automatically.

3. Pipeline: The PPISP method consists of multiple modules that work together to improve image quality by correcting for variations in lighting and color.

4. Results: PPISP significantly enhances the quality of reconstructed images for new views compared to existing methods and ground truth images.

Overall, PPISP offers a more reliable way to manage photometric variations in 3D reconstructions, leading to better outcomes in novel scenarios.

Summary of Reverse Engineering Sid Meier's Railroad Tycoon

The author, Wilczek_h, has spent three months reverse engineering the classic game Sid Meier's Railroad Tycoon due to frustrations with its limitations, such as a money cap and low resolution. The goal is to enhance the game for personal use and make it more accessible for his children, who enjoy building railroads without the competitive aspect.

Key achievements so far include:

• Extracting images and playing animations from the game.
• Creating a resolution-independent map that displays railroads and city names accurately.
• Successfully debugging the game's code using DOSBox and identifying how various game elements are stored and rendered.

Challenges faced include:

• The game's extensive use of overlays complicates debugging.
• Understanding how the game's graphics, particularly tracks and signals, are rendered required significant effort.

The author plans to continue working on the project, aiming to fix bugs, enhance game features, and improve gameplay experience. Future updates will be shared, although progress may be slow due to time constraints. The project is a mix of nostalgia and technical challenge, with a focus on preserving the original game's charm while adapting it for modern systems.

Summary of the Design of the Breccia Append-Only Blob Store

The Breccia blob store is designed to meet specific requirements:

1. Single-file and Append-Only: Data is stored in one file, where new data is added without changing existing data. This makes it easy to mirror the data by simply appending new information.

2. Discoverable: You can find blobs (data chunks) starting from any point in the file, allowing you to move back and forth through the data easily.

3. Low Space Overhead: Most of the file size is used for actual blob data rather than for storage overhead, even when blobs are small (less than 100 bytes).

4. Memory-map Compatibility: Blobs are stored as whole units, allowing for direct access to their bytes using memory mapping.

Non-Requirements:

• The design does not prioritize fast binary search for large blobs, as it assumes blobs are small enough that searching costs are minimal.
• It is a low-level storage solution, meaning applications need to handle higher-level functions like serialization and indexing themselves.

Blob Management:

To find the start and end of blobs, Breccia splits the file into 64-bit words and uses a specific marking system. Each blob begins with a unique 64-bit mark that indicates its position. When writing blobs, the system checks for potential conflicts with these marks and adds padding if necessary to avoid overlaps. This ensures that each blob can be stored without errors, while keeping padding minimal.

Thirteen years ago, Watsi.org was launched and quickly gained popularity, attracting significant support from the community and receiving funding from Y Combinator. The founder aimed to make Watsi more efficient and transparent than typical nonprofits, dedicating a lot of time to understanding users and coding.

Over the years, they realized that fundraising for nonprofits is different; people don’t think about donating as often as they do about buying a coffee or making money. Despite their efforts, donations grew slowly while the need for care increased rapidly, leading to burnout for the founder, who later stepped back to the board.

The founder acknowledged a mistake in tying their self-worth to Watsi’s success and felt pressure comparing the organization to for-profit companies. However, they ultimately accepted a more sustainable approach, resulting in Watsi's ability to fund over $20 million for 33,241 surgeries.

Now, with a new perspective, the founder is proud of Watsi's achievements and appreciates the ongoing support from donors and the community, emphasizing the importance of sticking with meaningful causes even when they aren’t in the spotlight.

The article discusses a study on how the feed algorithm of the social media platform X (formerly Twitter) impacts users' political attitudes. Researchers conducted a field experiment in 2023 where they randomly assigned U.S.-based users to either an algorithmic or chronological feed for seven weeks.

Key findings include:

1. Increased Conservative Engagement: Users who switched to the algorithmic feed showed greater engagement and shifted their political views toward more conservative positions, particularly regarding policies, perceptions of criminal investigations involving Donald Trump, and the war in Ukraine.

2. No Significant Effect from Chronological Feed: Conversely, switching from the algorithmic feed to a chronological feed had no noticeable impact on users' political attitudes.

3. Content Influence: The algorithm appears to promote conservative content while downplaying traditional media. Users exposed to algorithmic content began following more conservative accounts, which they continued to follow even after switching back to the chronological feed.

4. Persistent Effects: The study suggests that initial exposure to the algorithm has lasting effects on users' political beliefs and behavior, despite not significantly impacting their overall partisanship or affective polarization.

The researchers emphasize that their findings highlight the importance of algorithms in shaping political views on social media, contrasting with previous studies that found minimal political effects from feed algorithms on platforms like Facebook and Instagram. The study was approved by ethics committees and involved careful design and participant recruitment to ensure valid results.

Summary of "Semantic Diffusion" by Martin Fowler

Martin Fowler discusses the concept of "semantic diffusion," which occurs when a term loses its original meaning as it spreads through a community. This often happens with popular terms like "agile" and "Web 2.0," which were well-defined but have been misinterpreted or oversimplified by many.

Fowler explains that this diffusion is similar to the telephone game, where the original definition gets distorted as it passes from one group to another. This can lead to misunderstandings, especially when terms become popular and are discussed widely without reference to their original meanings. The desire for appealing terms also contributes to this issue, as people are drawn to concepts that sound attractive.

He notes that semantic diffusion is more likely with broad concepts than with specific technologies, and while it can be frustrating for those who value the original ideas, he believes terms can regain their meaning over time. Fowler prefers to keep re-defining and clarifying terms rather than abandoning them for new ones, as that would only create more confusion.

Additionally, he mentions "semantic inversion," where a term takes on an opposite meaning, like "DevOps" becoming associated with a separate operations team. Overall, Fowler advocates for the importance of maintaining clear definitions in the face of evolving language in the software development field.

The article discusses the growing concerns among white-collar workers regarding the future job market, particularly due to advancements in AI technology. Although most college graduates still find jobs, a significant shift is occurring: 25% of unemployed individuals have bachelor’s degrees, and high-school graduates are securing jobs faster than college graduates. Many office jobs are at risk of being automated, leading to layoffs in major companies.

If AI drastically reduces white-collar jobs, the U.S. may face a structural unemployment crisis, unlike past economic downturns where recovery mechanisms worked effectively. Current unemployment benefits are insufficient for high earners, who may struggle for years without jobs. A decrease in spending by wealthier households could negatively impact various sectors of the economy, worsening job losses and increasing inequality.

The article warns of a potential future where white-collar workers experience long-term unemployment similar to past blue-collar job losses, with negative effects on their well-being. To address these challenges, new workforce training and support systems are needed, though current programs have had limited success. Some propose a universal basic income (UBI) as a solution, but this raises concerns about societal acceptance and the potential loss of the work culture that many Americans value.

Overall, the future remains uncertain, and while technology has historically increased productivity, the impact of current AI advancements on employment is unclear.

The article discusses the idea of utopia, using the concept of a post-scarcity world where everyone's material needs are met, similar to the fantastical Land of Cockaigne. While this scenario sounds appealing, the author raises concerns about the potential downsides. The main points include:

1. Utopia's Appeal: A world without hunger or labor seems ideal, freeing people from daily struggles and anxieties.

2. The Problem of Meaning: There's a worry that without challenges, life might feel meaningless. The author argues that even in a resource-abundant world, interpersonal struggles and desires won't disappear, meaning life can still be fulfilling despite unhappiness.

3. Positional Goods and Status: In a utopia, people may still compete for status and respect, as these are relative and scarce resources. Achievements and titles still matter, leading to social hierarchies.

4. Desire and Relationships: Even in a perfect world, desires for affection and recognition may go unreciprocated, causing pain and dissatisfaction. This reflects a broader issue of wanting to matter to others.

5. Human Nature and Utopian Challenges: The author suggests that while material abundance can alleviate some problems, human nature—such as the desire for love and recognition—will persist, keeping life complex.

In summary, the article explores how a utopia might not eliminate dissatisfaction and struggle, as human relationships and the quest for meaning remain integral to the human experience.

Physicists are exploring ways to make electrons behave like flowing water, a concept that challenges traditional views of electricity. Typically, electrons move independently in a wire, unlike water, which flows cohesively. Recent experiments have shown that under certain conditions, electrons can form a fluid-like state, leading to new insights in quantum systems.

One significant breakthrough occurred when researchers demonstrated electrons creating shock waves similar to those seen in fluids. This indicates that electrons can move collectively at high speeds. Understanding this fluid behavior could pave the way for innovative electronic devices and offer a new perspective on quantum materials.

Key concepts include:

• Electron Movement: Electrons in wires behave like pinballs, bouncing off obstacles, rather than flowing smoothly like water.
• Gurzhi Effect: A theoretical prediction that if electrons could conserve momentum like water, heating them would improve conductivity, which has been observed in experiments with materials like graphene.
• Recent Experiments: Using advanced techniques, scientists have visualized electron movements and created structures that allow for fluid-like behavior, including the formation of electron whirlpools.
• Future Implications: This research may lead to new electronic components and a deeper understanding of quantum mechanics, as scientists apply fluid dynamics principles to electron behavior.

Overall, this emerging field could significantly change how we think about and utilize electrons in technology.

Summary: In Search of a Discord Replacement (February 16, 2026)

The author has been a long-time Discord user since 2016 but feels that the platform is declining due to unresolved bugs and recent mandatory age verification requirements. This has prompted them, along with their community, to seek alternatives to Discord.

They categorize the communities they manage into three types:

1. Large centralized communities - Require strong moderation tools and support for many users.
2. Productivity-focused communities - Also need effective moderation and tools for collaboration.
3. Small friend groups - Less demanding in terms of moderation.

Key requirements for a replacement include:

• User-friendly onboarding experience
• Multiple chat channels for organization
• Good mobile access
• Ability to self-host to avoid legal issues

Additional desired features are open-source software, privacy measures like end-to-end encryption, and support for video chat and screensharing.

The author rules out many popular platforms (like IRC, Telegram, WhatsApp, etc.) due to lack of self-hosting or other significant limitations. They explore various alternatives:

1. Matrix - Feature-rich but has poor user experience and difficult self-hosting.
2. Signal - Good for small groups but not ideal for larger communities.
3. Zulip - Strong candidate with a good feature set and usability, but its model is more business-oriented.
4. Fluxer.app and Sharkord - New projects aimed at replacing Discord but face issues like bugs and lack of mobile support.

The author concludes that while there are promising options like Zulip, many alternatives fall short of Discord's convenience. They plan to continue exploring alternatives and will update their findings as they try more options.

The Tech Oversight Project released a report on February 17, 2026, claiming that Mark Zuckerberg, CEO of Meta, lied during his 2024 testimony to Congress regarding the safety of social media for minors. The report highlights evidence that contradicts Zuckerberg's statements about Meta's commitment to protecting young users.

Key points include:

1. Lack of Effective Safety Measures: Despite Zuckerberg's claims of investing in teen safety, a study found that most of Instagram's safety features are ineffective, with 64% rated as either unavailable or ineffective.

2. Failure to Address Harm: An expert report indicated that Meta's platforms were not designed with child safety in mind, citing issues like weak age verification and harmful design features.

3. Mental Health Concerns: Internal documents revealed that Meta's own research linked Instagram to negative mental health outcomes for teens, especially concerning body image and anxiety, contradicting Zuckerberg's assertion that evidence of harm is lacking.

4. Child Exploitation: Meta allowed sex trafficking on its platforms, with a high threshold for account suspensions, and internal documents indicated a goal to attract younger users, despite laws prohibiting underage access.

5. Manipulation of Data: There are accusations that Meta downplayed the effectiveness of its content moderation tools, with internal whistleblowers claiming the true accuracy is much lower than reported.

Overall, the report argues that lawmakers need to enforce stricter regulations, like the Kids Online Safety Act, to hold Meta accountable for its practices and protect children online.

The author has tried many tools for querying PostgreSQL but found that raw SQL queries are the simplest and most effective for their needs. They previously had to manually type results and rely on tests to identify issues, which was particularly frustrating in TypeScript due to its complex type system and quirks in data deserialization. To address these challenges, they created a tool called pg-typesafe. This tool allows users to perform queries in the same way as node-pg while ensuring full type safety. Although it is new, the author has already used it in a larger project, where it helped identify bugs and reduce the need for manual type definitions.

Summary: How LLM Agents Threaten Open-Source Projects

In early 2026, concerns arose about the negative impact of Language Model (LLM) agents on open-source projects, sparked by a discussion about Tailwind CSS, a popular CSS framework. Tailwind Labs, the company behind Tailwind CSS, faced financial troubles partly due to LLMs reducing traffic to their documentation, which in turn affected sales of their paid products. This issue highlights a broader problem: LLMs use open-source code and documentation to generate answers and code, often without acknowledging the original sources, leading to decreased visibility and participation in open-source projects.

Additionally, aggressive AI crawlers from companies like Amazon have overburdened Git servers, increasing costs for open-source maintainers and disrupting services. Some developers have created tools to trap these crawlers and protect project resources, but such defenses can also hinder legitimate users. A significant portion of traffic to open-source projects now comes from these bots, complicating the sustainability of the projects.

LLM agents have also created challenges like generating fake bug reports that waste developers' time. Projects like Curl have had to implement strict measures to combat this issue, including blocking certain reports and discontinuing their bug bounty program.

Moreover, LLM agents have begun to autonomously interact with open-source communities, leading to situations where they can manipulate perceptions and damage the reputations of maintainers. This raises concerns about accountability and the integrity of open-source contributions.

Overall, the rise of LLM agents threatens the foundations of trust and responsibility in open-source ecosystems, as they can act without clear attribution or accountability, undermining the hard-earned credibility of many projects.

Summary

Recent research by the AI security company Irregular reveals that passwords generated by popular AI tools like Claude, ChatGPT, and Gemini may seem complex but are actually predictable and vulnerable. When tested, these AI-generated passwords were found to have common patterns that could be exploited by hackers, allowing them to be cracked in just a few hours.

The study showed that many generated passwords were not unique and often started and ended with the same characters. While online password checkers rated these passwords as strong, they failed to recognize these patterns, leading to a misleading assessment of their security.

Irregular found that the entropy, or randomness, of these passwords was significantly lower than that of truly random passwords. The AI-generated passwords had an estimated entropy of only 20 to 27 bits, compared to the 98 bits expected from random passwords. This means they could easily be brute-forced.

Experts advise against using AI-generated passwords, stating that they are fundamentally weak, and recommend using third-party password managers instead. The findings highlight the need for caution when relying on AI for secure password generation, as the predictable nature of AI outputs compromises security.

A developer and father created an educational tool called Qurio after noticing his daughter was relying on ChatGPT for her history homework without truly learning. He believes the issue isn't the AI itself, but that many kid-friendly AI apps simply give easy answers, which hinders real learning.

Qurio aims to change this by treating children as future thinkers rather than just executors of tasks. It uses a method called the "Socratic Loop," which avoids giving direct answers and instead asks guiding questions to encourage critical thinking. This approach adds "Healthy Friction" to the learning process, promoting genuine understanding.

The tool is built using Next.js 14, Supabase for authentication and database, and the Vercel AI SDK.

The author expresses concern about the increasing use of coding agents in the tech industry, which they compare to gambling due to their addictive nature. As companies push for more productivity, they encourage or require the use of these tools, leading to a work culture where employees are always "on" and working. This trend mirrors the "996" work schedule from China, and the author fears it may become the norm in tech.

The author argues that coding agents generate low-quality work and require constant supervision, making them akin to slot machines where users repeatedly try to achieve the best results. They suggest that this leads to a form of addiction to work, as heavy users report symptoms similar to gambling addiction.

The author worries about the erosion of work-life balance and ethical standards in the industry, suggesting that some companies may prioritize productivity at the expense of employee well-being. They conclude with a personal note about considering a career change due to these pressures.

Google DeepMind's recent paper discusses a new chess-playing model that uses transformers, trained on the powerful chess engine Stockfish 16. This model outputs three key components: the value of a game state, the value of specific actions, and a probability distribution over possible moves. After training, it plays chess by selecting the best action based on these outputs, similar to DeepMind's AlphaZero.

The authors claim their model plays at a Grandmaster level, achieving an impressive Lichess Blitz rating of 2895. However, this rating might not hold in longer time controls, as the model can't think more deeply like a human can. Critics argue that the results may not be new, as open-source projects like Leela Chess Zero have surpassed AlphaZero's performance significantly.

The paper also raises concerns about the authors' comparisons between their model and Stockfish, particularly since they reference opinions from human players who are weaker than Stockfish. Overall, the critique suggests that the paper may overlook important existing research and lacks serious rigor.

Summary: Async/await on the GPU

VectorWare has announced a significant advancement: Rust's async/await feature can now be utilized in GPU programming. This allows developers to create complex, high-performance applications using familiar Rust tools.

Key Points:

1. New Capability: Rust's async/await can now run on GPUs, enabling better concurrent programming without needing to manually manage tasks.

2. Traditional GPU Programming: Historically, GPU programming focused on data parallelism, where the same operation runs on different data parts simultaneously. More complex tasks required developers to manage concurrency, which can be error-prone.

3. Current Approaches: Projects like JAX, Triton, and CUDA Tile have emerged to simplify GPU programming by structuring code around tasks and data dependencies. However, these require developers to adapt to new programming paradigms, which can hinder adoption.

4. Rust's Solution: Rust's Future trait and async/await offer a way to write concurrent code without a new language or ecosystem. This abstraction allows for flexibility in execution and maintains compatibility with existing code.

5. Demonstration: VectorWare showcased running async functions on the GPU, illustrating that complex workloads can be expressed using Rust's async model.

6. Executor on the GPU: Initially, a simple executor was used, but they later adapted the Embassy executor for better performance on GPU hardware.

7. Challenges: While Rust's async model offers many advantages, it also faces challenges such as potential performance degradation due to cooperative multitasking and increased register pressure.

8. Future Plans: VectorWare aims to explore GPU-native executors and enhance integration with Rust's standard library for richer functionalities. They plan to support multiple programming languages in future products.

For updates on their progress, VectorWare encourages following their blog or reaching out via email.

Summary of GrapheneOS - Break Free from Google and Apple

Introduction:
The author shares their journey of moving away from the Apple ecosystem to explore alternatives, leading them to GrapheneOS, an open-source operating system focused on privacy and security.

What is GrapheneOS?
GrapheneOS is a secure operating system based on Android that removes Google services to enhance privacy. It allows for the use of apps in a controlled environment, minimizing tracking and data collection.

Supported Devices:
GrapheneOS is primarily compatible with Google Pixel devices, which are recommended for their security features.

Installing GrapheneOS:
The installation process involves several steps:

1. Preparing the phone and unlocking the bootloader.
2. Downloading and flashing the GrapheneOS image.
3. Re-locking the bootloader for security.

Using GrapheneOS:

• The author created multiple user profiles for better privacy management.
• They use Obtainium for open-source app management and Aurora Store for downloading apps without Google services.
• GrapheneOS offers full control over app permissions, enhancing user privacy.

Private Space Feature:
GrapheneOS allows users to create a private space, keeping certain apps isolated from the main user profile for added security.

Conclusion:
The author appreciates the flexibility and privacy GrapheneOS provides, encouraging support for the project due to its importance in promoting user freedom from major tech companies.

You can easily test Plasma by using a live image from a USB disk. Another option is to use Docker images for a quick trial. You can download both types of images to get started.

I created a fun browser-based camera tool inspired by circuit bending, which allows users to "rewire" camera settings to create glitch effects in real-time photos. You can adjust knobs to achieve various visual effects, such as color changes and delays.

I aimed for a nostalgic design that resembles the look of physical buttons, similar to those on Teenage Engineering devices.

To build this project, I used GPT-5.3-Codex, but I found it challenging. While it helped with some basic coding, it required a lot of manual adjustments and didn't fully capture the desired design details.

Feel free to try it out! Your photos and videos are processed locally in your browser, meaning they remain private and can be downloaded if you want.

The author wrote a book about computer history because they couldn't find one that combined storytelling with technical details. After five years of work, they are excited to share their book, which includes a lot of code. The author enjoys programming languages like Smalltalk and Lisp, and currently focuses on Common Lisp for their projects. They plan to write more books after retiring, possibly on topics like Smalltalk or computer networks. The author also thanks Dick Gabriel for sharing memories about John McCarthy, a key figure in computer history.

Discord's new age verification requirements have upset many users, leading to a significant number leaving the platform for TeamSpeak, a rival voice-chat service. TeamSpeak reported its servers are overwhelmed with new users, particularly in the U.S., as it promotes itself as a privacy-focused alternative.

The backlash against Discord stems from its implementation of privacy-invasive measures, influenced by the UK’s Online Safety Act, which mandates age verification for social media and adult content sites. This has caused frustration among users, especially after a data breach exposed sensitive information of 70,000 users.

Discord's recent decision to distance itself from a controversial age verification firm linked to surveillance issues has not helped its reputation. Meanwhile, TeamSpeak is expanding to accommodate the influx of users, announcing new regions for community creation.
