Bodycam footage has been released showing the shooting of Ruben Ray Martinez, a 23-year-old US citizen, by an ICE agent during a traffic stop in Texas on March 15, 2025. Martinez was driving near a road accident where ICE officers were directing traffic. The Department of Homeland Security (DHS) stated that Martinez "accelerated forward" and hit an agent, prompting another agent to fire shots.

However, attorneys for Martinez's family argue that the footage suggests he was barely moving and was not a threat when shot. The incident has raised questions about the official account of what happened. Martinez's friend, who was in the car, claimed that no officers were hit and that the agent fired without warning.

Martinez was found to have alcohol and marijuana in his system at the time of the incident. A Texas grand jury chose not to indict the officer who shot him. Martinez's mother has expressed concerns about the rise in violence from immigration enforcement and noted that she does not blame Trump directly for her son's death but calls for changes in the agency's practices.

This text discusses the implementation of a programming language feature called "match statements" in a language referred to as "Purple Garden." Here are the key points:

1. Match Statements: The author prefers using match statements instead of traditional if-else chains for cleaner control flow. An example is provided showing how to implement greetings based on the time of day using match statements.

2. Pipeline Architecture: The language's design includes an intermediate representation (IR) that uses a structure of functions and basic blocks. Each block contains parameters, instructions, and a terminator, ensuring that values are defined immutably and exactly once.

3. Parsing: The parsing process involves turning source code into an abstract syntax tree (AST) using recursive descent parsing combined with Pratt parsing techniques.

4. Type Checking: The type system in Purple Garden is simple and checks that all conditions in match statements are boolean and that all branches return the same type. Errors are raised when these conditions are not met.

5. Lowering to IR: The AST is lowered to IR using basic blocks and static single assignment (SSA), which ensures each instruction is defined only once.

6. Bytecode Generation: The IR is further lowered to bytecode that can be executed by a virtual machine. The text provides examples of how this conversion takes place, including handling instructions and terminators.

7. Optimization: The text briefly mentions optimizations such as removing useless blocks and potential future improvements, like tail call optimization and smarter register usage.

8. Example: A factorial function is used to illustrate the match statement's implementation, its lowering to IR, and the resulting bytecode. The author emphasizes the performance of the language and mentions benchmarks.

Overall, the text outlines the design and implementation details of the Purple Garden programming language, focusing on how match statements are constructed and executed efficiently.

The text discusses a project focused on querying 3 billion vectors, which are arrays of floating point numbers used to find semantically similar items, often in applications like search and recommendations. The author starts with a basic implementation to compare a small number of query vectors against a large set of document vectors, storing them in a simple format on disk.

Initially, the author notices that the naive approach is inefficient, taking nearly 2 seconds to compute similarities for just 3,000 vectors. By optimizing the code to use vectorized operations, execution time improves dramatically to about 0.01 seconds. Further tests with 3 million vectors take around 12 seconds, indicating scalability issues as memory requirements for handling 3 billion vectors would exceed available RAM.

To address this, the author suggests using techniques like batching operations and implementing libraries optimized for similarity comparisons, potentially in languages like Rust or C. They also raise important questions about project requirements and assumptions that could affect the implementation, highlighting that understanding these aspects can be more challenging than the technical work itself.

The text contains links to posts by Joseph Politano but doesn't provide any specific information or context about their content. Therefore, there are no key points to summarize or simplify.

The text discusses a method for editing changes in Jujutsu Version Control System (VCS) using a custom script.

1. Problem: The author needed to rename a method in a Jujutsu change but found the built-in editing tools insufficient. Renaming methods with LSP in Python can be unreliable.

2. Current Solutions:

   • Using jj show to view changes and manually replace words in an editor.
   • A less clean method involves replacing all occurrences and then using jj absorb to modify just one change.

3. Limitations of Jujutsu: Unlike Git, which allows easy patch editing with commands like git format-patch, Jujutsu lacks similar commands. However, it has jj diffedit, which allows line selection but not content modification.

4. Custom Tool: The author created a shell script that integrates diff and patch tools with Jujutsu. This script enables the user to edit the contents of a change by generating a patch file, allowing for easier editing.

5. Script Functionality:

   • It uses a temporary directory to handle the states before and after the change.
   • The script applies the original diff and then applies the user's modified version.

6. Registration: To use the script, the user must register it in Jujutsu’s configuration file, allowing it to be called with jj diffedit.

7. Outcome: Once set up, users can edit changes easily by opening the patch in their preferred editor, making the process smoother and more efficient.

This method provides a workaround for Jujutsu users needing to modify change contents effectively.

A recent study from Cornell University highlights that employees who are drawn to vague corporate jargon, such as “synergistic leadership” or “growth-hacking paradigms,” may struggle with practical decision-making. The research, led by cognitive psychologist Shane Littrell, introduced the Corporate Bullshit Receptivity Scale (CBSR), which measures how susceptible individuals are to confusing corporate language.

Littrell describes corporate bullshit as abstract language that sounds impressive but lacks real meaning, making communication more confusing rather than clearer. The study found that workers who are more receptive to this type of language tend to rate their supervisors as charismatic but score lower on tests measuring critical thinking and decision-making skills. This creates a cycle where employees who embrace corporate jargon may unintentionally support ineffective leadership.

The study suggests that while such jargon can make employees feel inspired and satisfied with their jobs, it can also lead to poor business decisions and potential reputational damage for organizations. Examples include a 2009 Pepsi presentation and a 2014 Microsoft memo that were criticized for their excessive use of jargon.

Overall, Littrell emphasizes the importance of critical thinking and encourages individuals to scrutinize corporate messaging rather than accept it at face value. The CBSR scale could be useful for assessing potential job candidates' analytical skills in the future.

5. Best Practices: Operators should use metrics tools to analyze the Tor network, avoid ISPs with high existing Tor capacity, and respond promptly to any abuse complaints received.

Overall, the guide is a resource for potential Tor relay operators, providing essential information on ISPs, best practices, and community resources.

In 2008, when the iPhone was first released, there were no emoji available. It wasn't until 2011 with iOS 5 that everyone could access an emoji keyboard. Before this, only Japanese iPhone users had emoji, leading to a unique situation.

Some developers found a way to enable emoji for non-Japanese users by tweaking settings within the iPhone. They created apps that made this process easier, but Apple initially resisted these efforts by rejecting some apps that promoted emoji. Developers then became creative, hiding emoji enablement in other apps, such as a $0.99 RSS reader.

Eventually, Apple relaxed its stance, and by 2011, emoji support was universally available, although users still had to enable it in settings. An interesting fact is that both the sender and receiver had to follow the same steps for emoji to work, adding to the confusion. Notably, a developer named Steven Troughton-Smith was the one who discovered how to unlock emoji for all iPhones back in 2008.

The text discusses handling context cancellation in Go, particularly focusing on the new features introduced in Go 1.20 and 1.21 that allow developers to attach specific reasons to context cancellations. Here are the key points:

1. Understanding Context Cancellations: When a context is canceled, the errors returned are often vague, like context.Canceled or context.DeadlineExceeded, making it difficult to identify the cause.

2. New Features: Go 1.20 introduced WithCancelCause, which allows developers to specify a reason for cancellation. This helps in debugging and understanding failures better.

3. Using Context with Timeout: The new WithTimeoutCause lets you also label timeout events with a specific reason. However, there is a subtlety: if the function returns before the timeout, the cause may be lost.

4. Manual Timer Pattern: To ensure all paths are covered, including normal completion and timeouts, a manual timer using WithCancelCause is recommended. This allows for more consistent cause tracking.

5. Error Handling: The text explains how to handle errors effectively and log them, providing a clearer picture of what went wrong in the application.

6. Middleware and Context: It suggests wrapping request contexts with WithCancelCause at the middleware level, allowing downstream handlers to set specific cancellation reasons.

7. Practical Usage: The author shares practical examples and patterns for implementing these features in real-world applications, emphasizing the importance of capturing and logging cancellation reasons.

Overall, the new cause-tracking capabilities in Go significantly improve the debugging process and provide clearer insights into context cancellations.

In a recent incident, developer Alexey Grigorev experienced a major setback when the AI tool Claude Code accidentally deleted his website's entire production setup, wiping out 2.5 years of important data. Grigorev was attempting to migrate his site, AI Shipping Labs, to a new server setup but failed to upload a crucial state file. This oversight led Claude to create duplicates and, when trying to fix the issue, the AI executed a command that destroyed both his site and its backups.

Fortunately, Amazon Business support was able to help restore the lost data within a day. After the incident, Grigorev shared lessons learned, including the importance of testing backups, applying delete protections, and manually reviewing AI commands instead of relying on the AI's judgment. He acknowledged that he had given too much trust to the AI and planned to change his approach to avoid similar mistakes in the future. This story highlights the risks of using AI without proper oversight, especially in a production environment.

The author reflects on their experience with social media, particularly after moving from Twitter to Mastodon when Twitter was taken over by an unsavory figure. Initially, they didn't see themselves as part of an online community and preferred using social media to stay in touch with real-life connections. However, as traditional media in the U.S. became untrustworthy, the Fediverse emerged as a reliable source of information.

The author criticizes platforms like Threads and Bluesky, viewing them as lacking substance and overly focused on branding rather than genuine communication. In contrast, the Fediverse allowed for authentic exchanges of knowledge without the clutter of commercial interests or algorithms that manipulate content. This shift became particularly important during political tensions, like when Trump threatened to invade Greenland, highlighting the value of connecting with knowledgeable individuals directly.

Ultimately, the author finds beauty in the simplicity of sharing information within the Fediverse, contrasting it with the decline of mainstream journalism, which led them to seek trustworthy news from everyday people instead.

The comparison is valid because the Vercel AI SDK is a common choice for building AI chat applications with Next.js. The goal was not to find the absolute fastest options but to demonstrate what typical development choices lead to. The Vercel SDK is popular, well-maintained, and follows best practices for React and Next.js, making it a good example for real-world single-page application (SPA) development.

Summary of htmx Infinite Scroll

Pagination is an important feature in web development, often implemented using tools like Pagy to load records in batches, provide navigation links, and allow bookmarking. However, many users leave after not finding what they want within the first few pages. Infinite scrolling improves user experience by allowing users to continuously scroll and search for content without the limitations of traditional pagination.

To implement infinite scrolling using htmx, you need to add the htmx library to your web application. This approach allows users to load more content as they scroll down, enhancing their browsing experience.

Key Steps to Implement htmx Infinite Scroll:

1. Setup:

   • Include the htmx library and gem in your Ruby web framework.
   • Create HTML elements that trigger requests to load more data when they come into view.

2. Backend Implementation:

   • Create a Hanami action that handles requests and responses.
   • Use optional parameters for search queries and pagination.
   • Load photos based on parameters and respond with either the requested data or an error message.

3. View and Template:

   • Expose necessary data (photos, query, page) to the view.
   • In the template, iterate over the photos and handle the display of results, including a loading message when fetching more data.

By leveraging htmx, you can enhance your application with a more efficient user interface that maintains browser history and reduces the amount of JavaScript needed. This leads to a faster, simpler, and cleaner web application.

Summary:

Don Knuth recently discovered that an open problem he was working on had been solved by Claude Opus 4.6, a new generative AI model. The problem involved finding a way to break down directed graphs (digraphs) into Hamiltonian cycles for graphs with a specific number of vertices. Knuth had made progress for a small case, and his colleague Filip Stappers found solutions for larger cases.

Claude Opus explored various strategies to tackle the problem, including reformulating the question, testing different mathematical approaches, and using computational methods like depth-first search and simulated annealing. Ultimately, Claude found a successful method for odd values of the number of vertices (m), demonstrating that valid decompositions exist.

The findings were significant, leading to a conclusion that Claude's construction works for all odd values of m greater than 1. The work is ongoing for even values, but initial attempts have shown promise.

Knuth expressed excitement about the advancements in AI and problem-solving, illustrating how modern technology can contribute to solving complex mathematical problems. The journey involved multiple explorations, adjustments, and collaboration, highlighting the evolving nature of research in computer science.

Summary:

A performance issue was discovered in an application using Dapper with SQL Server, where a simple query was consuming excessive CPU resources due to a type mismatch. The problem arose because C# strings were being mapped to nvarchar instead of varchar, causing SQL Server to convert values, preventing index use and leading to slow query performance.

To fix this, developers should explicitly state that parameters are varchar using DynamicParameters and DbType.AnsiString. This ensures SQL Server can use the correct index, resulting in significantly improved performance.

Key points for developers:

• Use DbType.AnsiString for varchar columns.
• Match the size of the parameter to the column definition.
• Avoid anonymous objects for string parameters on varchar columns to prevent performance issues.
• Audit existing queries for this issue to improve efficiency.

Overall, being mindful of parameter types in Dapper can dramatically enhance SQL Server performance without needing any schema changes or complex rewrites.

The author loves writing code and enjoys the problem-solving aspect of it. Recently, they have been using AI to help them create systems and tools, making the coding process more efficient and enjoyable. They believe that AI can produce high-quality code when guided properly, but many people overlook this potential and dismiss AI-generated code as poor quality.

The author is currently working on a complex project where AI helps with the technical details while they focus on the overall architecture. This approach allows them to complete tasks much faster than before. They emphasize that the skill now lies in knowing what to build and how to design it, rather than just writing code.

While the author acknowledges the benefits of AI, they stress that a solid foundation in software engineering is still crucial. This knowledge helps them know when the AI is wrong and how to ask the right questions. They encourage others to build this foundational knowledge since resources for learning are widely available today.

In summary, the author feels that everyone can become an AI Engineer, and they value teams that are curious about AI and its implications. They also clarify that they closely review AI-generated code and understand the importance of knowing when to use AI tools effectively.

Two young billionaires, Tarek Mansour of Kalshi and Shayne Coplan of Polymarket, lead the prediction market industry but are in a fierce rivalry. Mansour avoids naming Polymarket directly, emphasizing that Kalshi is a regulated platform, unlike Polymarket, which he criticizes for being unregulated and offshore. This competition intensified after an FBI raid on Coplan's home, prompting Kalshi staff to mock Coplan online.

Mansour likens their feud to famous sports rivalries, pushing his team hard to distinguish Kalshi from Polymarket. Both companies are seeing significant growth, with billions in bets on various events, but they have different approaches to regulation. Mansour believes in cooperating with regulators, while Coplan has taken a more aggressive, unregulated route.

Kalshi has worked to gain approval from the Commodity Futures Trading Commission (CFTC), while Polymarket operates mostly overseas and has faced criticism for its controversial betting options. Despite their rivalry, both companies aim to prove that prediction markets can provide valuable insights beyond traditional media. Recent actions from both sides, including partnerships with major media outlets and aggressive marketing strategies, illustrate their ongoing competition for dominance in this emerging market.

The article discusses recent file-system benchmarks conducted using the Linux 7.0 kernel. It evaluates the performance of four main file-systems: Btrfs, EXT4, F2FS, and XFS, all tested under their default settings. Btrfs was also tested with its copy-on-write feature turned off for comparison.

The benchmarks were performed on a Solidigm D7-PS1010 PCIe 5.0 NVMe SSD using an AMD EPYC 9745 server. The results will help highlight how these open-source file-systems perform against each other. Although OpenZFS and Bcachefs were planned for testing, they were not included because their latest versions are not yet compatible with Linux 7.0. Further tests will be done once they become compatible.

The text explores the historical development of military technology and the ethical concerns surrounding it, focusing on six key figures and their inventions.

1. Richard Gatling (1861): He invented the Gatling gun, aiming to reduce the need for large armies and minimize casualties in war.

2. Hermann Oberth (1923): His work on rocketry inspired a movement in Germany for space travel. The Verein für Raumschiffahrt (VfR) formed in 1927 to pursue these ideas but declined due to financial struggles and the rise of the Nazi regime, which absorbed many members into military projects.

3. Alberto Santos-Dumont: Often credited with inventing the airplane, he initially saw military uses for aviation but later expressed regret over its violent applications during WWI and sought to promote peace instead.

4. Alfred Nobel: He invented dynamite, which he believed could be used for peaceful purposes, but became increasingly concerned about its military applications. Despite his peace efforts, he remained convinced that technological advancements would ultimately lead to peace.

5. Mikhail Kalashnikov: The inventor of the AK-47 reflected on the guilt of creating a weapon that took lives, questioning the morality of his contribution to warfare.

6. Leo Szilárd: After fleeing Nazi Germany, he helped initiate the Manhattan Project to develop nuclear weapons but later warned against their use without international control, fearing an arms race.

Overall, the text illustrates a recurring theme: inventors grapple with the consequences of their creations, particularly when they lead to destruction rather than peace.

Summary:

Researchers at the Indian Institute of Science, led by Professor Kavita Babu, are studying social behavior in worms called Caenorhabditis elegans to understand how certain brain pathways, particularly the serotonin pathway, are regulated. They found that mutating a single gene, CASY-1, caused the worms to swarm together instead of moving individually towards food, even at the risk of starvation.

This swarming behavior is similar to patterns seen in other species and suggests that social behavior might be genetically encoded. The researchers collaborated with physicists to model the worms' movements and discovered that swarming could emerge from just one worm over generations. They also used techniques like CRISPR to create genetic mutants and confirmed that serotonin signaling plays a key role in how these worms interact as a group.

Future research will explore how different genetic changes affect behavior in various environments, aiming to uncover fundamental principles of collective behavior across species.

Gobhanu and Saatvik, brothers who created Vela, are developing AI agents to simplify multi-party scheduling across different communication channels. Scheduling can be complicated, especially when multiple people, time zones, and informal communication are involved. Vela aims to automate this process so that, for instance, a recruiter can send one message and have all interviews scheduled and confirmed without the usual back-and-forth emails.

Vela integrates with various platforms like email, SMS, WhatsApp, and Slack, reading context, checking calendars, suggesting times, and following up as needed. One of their first clients, a staffing firm, had been looking for a scheduling solution for eight years and found that Vela solved their issues quickly.

The main challenge is understanding different scheduling behaviors across various groups. For example, executives may prefer formal emails, while truck drivers might respond informally via SMS. Vela is building datasets to understand these differences better.

Another challenge is managing communication across different channels without losing context. Vela needs to track conversations that start on one platform and continue on another, while also understanding the nuances of language and timing.

Vela is already live with paying customers and continuously learns from new cases. They welcome feedback from anyone with experience in multi-agent coordination or conversational AI. You can find more information and a demo on their website.

In a recent update, Don Knuth expressed surprise and excitement that an open problem he had been exploring was solved by Claude Opus 4.6, a generative AI model from Anthropic. The problem involves finding Hamiltonian cycles in a specific directed graph (digraph) with a formula defined for vertices and arcs. Knuth had previously solved the problem for a small case (m=3) and received support from his friend Filip Stappers, who helped test larger cases.

Claude Opus systematically approached the problem through various explorations, reformulating it and attempting different methods like depth-first searches and analyzing patterns. While it faced challenges, Claude eventually discovered a method that worked for odd values of m (3, 5, 7, 9, and 11) and produced valid Hamiltonian cycles, confirming that the problem was solved for these cases.

Despite this success, the quest for solutions for even values of m remains open. The AI’s explorations were sometimes hindered by errors and required careful documentation of progress. However, recent advancements in AI have led to further breakthroughs, including a potential solution for even m values as high as 2000.

Overall, Knuth's experience highlights the significant advancements in AI's ability to tackle complex mathematical problems, showcasing a collaborative effort between human intuition and machine learning.

The Pentagon is under scrutiny after airstrikes in Iran killed 165 people, mainly elementary students, including a strike on a girls' school. Reports suggest the Pentagon used an AI model called Claude to plan these military operations. The possibility that AI influenced the decision to attack a school raises significant ethical concerns.

The attack in Iran is reminiscent of previous military actions, where AI systems helped select targets, such as the Israeli army's use of an AI called "Lavender" in Gaza, which reportedly identified thousands of targets. This trend indicates a shift in warfare, where AI may play a central role in life-and-death decisions, often with minimal human oversight.

The Pentagon has not confirmed whether AI was used in this specific incident. The situation highlights the dangerous implications of using AI in military strategies, particularly when it leads to civilian casualties.

The text discusses the implications of surveillance technologies and AI in Iran, particularly how these tools were originally used for oppression but ultimately contributed to the downfall of regime leader Ali Khamenei. The author recounts a personal experience with police surveillance in Iran and highlights how advanced technologies, like traffic cameras and AI, were employed by the regime to enforce strict laws, such as mandatory hijab wearing. However, these same technologies were exploited by Israeli intelligence to track Khamenei, leading to his assassination.

The article emphasizes the irony that tools designed for control can become vulnerabilities for those in power. It also illustrates acts of defiance by Iranian citizens against surveillance, such as covering cameras with menstrual pads or destroying them during protests. The author reflects on the cyclical nature of oppression and resistance, suggesting that oppressive systems can ultimately harm their creators. The piece serves as a reminder of the fragility of authoritarian control in the face of resistance movements.

FurSquared, a furry convention, switched from using HID DTC1250e printers to Zebra ZD420C printers for registration badges. This change was made to improve efficiency and quality, as the old printers had issues such as slow printing times and high maintenance costs.

Badges are important at furry conventions because they help attendees express their identities and ensure safety by allowing for easy identification. Custom badges also serve as memorabilia after the event. The previous printers were unreliable and costly, requiring frequent replacements and extensive troubleshooting.

The Zebra printers are faster and more reliable, significantly reducing the time needed to print badges. The convention adopted a server-based printing system to streamline the process, eliminating the need for manual printer selection and minimizing operator error. This setup allowed for a smoother registration experience with shorter lines.

However, some technical challenges arose during implementation, including hardware compatibility issues and network problems. Despite these setbacks, the registration process improved greatly, with lines remaining manageable throughout the convention.

In conclusion, the transition to Zebra printers and an automated printing system enhanced the registration experience at FurSquared, making it more efficient and user-friendly.
