Coreboot Enables AMD Turin Support on Gigabyte MZ33-AR1: Phase 1 Complete

2025-08-16

This blog post details the first phase of enabling AMD Turin support in coreboot and porting it to the Gigabyte MZ33-AR1 motherboard. Funded by the NLnet Foundation, the project builds upon AMD's push for open-source firmware. The team successfully created the Turin SoC structure within coreboot, extracted and integrated the necessary PSP firmware packages, and built basic MZ33-AR1 motherboard support. While challenges remained with integrating public Turin PSP blobs, workarounds allowed a successful boot, paving the way for future improvements.

Building Efficient AI Agent Systems: Lessons from UserJot

2025-08-16

UserJot experimented with building a multi-agent AI system to analyze customer feedback at scale and auto-generate changelogs. The author shares key learnings, centering on a two-tier architecture: primary agents manage context and task decomposition, while stateless sub-agents focus on single tasks. Efficiency comes from task decomposition (vertical and horizontal), structured communication protocols, agent specialization, and orchestration patterns like MapReduce. The article stresses statelessness, context management strategies, and error handling, offering performance optimization tips and monitoring metrics.

Unexpectedly Slow: A Simple Socket Benchmark Shows Linux Lagging Behind OpenBSD

2025-08-16

A simple C program creating threads and opening 256 sockets reveals a surprising performance disparity between Linux and OpenBSD. On Linux, execution times fluctuate between 17 and 26 milliseconds; on OpenBSD, they're a mere 2 to 6 milliseconds. Adding to the intrigue, OpenBSD initially threw a "too many open files" error, hinting at differences in resource management. The author notes the discrepancy isn't related to networking code and challenges readers to find a Linux system that outperforms OpenBSD in this benchmark.

47 Seconds of Gym Hell: How I Fixed PureGym's Broken Check-in with Apple Wallet

2025-08-16

An iOS developer's frustration with PureGym's app (47 seconds to check in!) led him on a wild ride. He discovered laughably insecure APIs – an 8-year-old unchanging PIN was more secure than the minute-refreshing QR code. Using mitmproxy, he reverse-engineered the system, built an Apple Wallet pass using PassKit, and slashed check-in time to 3 seconds. The article details the process: reverse engineering, certificate wrestling, Swift backend development, and more. He even integrated it with Home Assistant. A humorous and technically detailed personal project highlighting the importance of user experience.

Git's Large File Killer: The End of Git LFS is Nigh

2025-08-16

Large files have long been a thorn in Git's side. Git LFS, while a solution, introduced new complexities and costs. However, Git itself is gradually addressing this issue. The latest Git releases feature partial clones, offering the same benefits as Git LFS—fast clones and small checkouts—without the need for extra tools or server-side costs. Even more exciting, Git's large object promisors are under development, promising to eventually obsolete Git LFS entirely, making large file management simpler and more efficient. No more large file headaches!

Kanji Amnesia: Why I Remember the Meaning But Not the Writing

2025-08-15

The author mastered kanji by first learning their meanings and writing, then pronunciation. Years later, he can't handwrite most kanji. This 'Kanji Amnesia' is common in Japan and China. He explores the brain's separate processes for reading and writing, and his aphantasia (lack of mental imagery) adds to the mystery. Cognitive science suggests this stems from the brain's use of both verbatim and gist memory traces. Reading involves recognizing the gist, while writing activates motor memory of strokes – two distinct skills.

LLMs: Great Code Generators, Terrible Software Engineers

2025-08-15

Years of interviewing software engineers reveals that building and maintaining clear mental models is key. While LLMs are good at generating and modifying code, they lack the crucial ability to maintain these models. They easily get confused, suffer from context omission and recency bias, and hallucinate details, preventing iterative problem-solving for complex tasks. The author concludes that LLMs are helpful tools for software engineers but cannot yet replace them for anything beyond simple projects.

Deprecate XSLT in Browsers?

2025-08-15

Browsers' built-in XSLT processor (v1.0, standardized in 1999) is outdated and poses security risks. Modern web development uses JavaScript and JSON, rendering XSLT largely obsolete. Maintaining aging XSLT libraries (like libxslt in Chromium) is resource-intensive and prone to memory safety vulnerabilities, creating a significant attack surface. This proposal suggests deprecating XSLT from web standards to reduce security risks and optimize resource allocation, with no practical loss of developer functionality.

Simulating and Visualizing the Central Limit Theorem: A Practical Exploration

2025-08-15

This post explores the Central Limit Theorem (CLT) through simulation and visualization. The author, having previously avoided statistics, uses R to generate samples from various distributions (uniform, normal, binomial, beta, exponential, chi-squared) and calculates sample means. The results visually demonstrate how the distribution of sample means approaches a normal distribution as sample size increases, confirming the CLT. The post further investigates the practical implications of using the t-distribution instead of the normal distribution for confidence interval calculations when dealing with limited sample sizes and unknown population variance. Simulations highlight the difference in confidence interval coverage across various sample sizes. Finally, an animation showcases how the distribution of sample means converges to a normal distribution as the sample size grows, offering a compelling visual understanding of this fundamental statistical concept.

MacBook Notch Breaks Game Rendering: A Developer's Nightmare

2025-08-15

Many games render incorrectly on MacBooks with notched displays. The issue stems from how games obtain screen resolutions (CGDisplayCopyAllDisplayModes), which returns resolutions including the notch area, resulting in compressed and distorted game visuals. The article analyzes the differences between various screen regions (full screen, safe area, AppKit fullscreen area) and offers a solution for filtering resolutions. However, it ultimately points to Apple's API design as the root cause. The article also lists affected games and potential improvements Apple could implement, such as updating the HIG, improving CGDisplayMode, or creating a new game-centric API.

Linux Copy & Paste Gets a Retro Upgrade: Say Goodbye to Ctrl+Shift

2025-08-15

Tired of Ctrl+Shift+C/V for copy and paste in Linux terminals? Good news! By the end of 2025, most Linux applications will natively support the legacy 'Copy' and 'Paste' keycodes. This is thanks to the rise of programmable keyboards and support for these keycodes in software toolkits like GTK and QT. Several terminal emulators like Alacritty, Foot, and Wezterm already support them, while Gnome Terminal and Konsole are expected to support them after updates by the end of the year. This will revolutionize the Linux copy-paste experience, making it more convenient and efficient.

Ghostty's GTK Rewrite: A Triumph of GObject and Valgrind

2025-08-15

The Ghostty terminal emulator's GTK application underwent a complete rewrite, fully embracing the GObject type system from Zig and rigorously using Valgrind for memory verification at every step. The result is a more feature-rich, stable, and maintainable Ghostty on Linux and BSD. The rewrite addressed previous memory management issues stemming from avoiding the GObject system, simplifying tasks like configuration reloading using GObject's property change notification system. Valgrind uncovered a few memory issues, mostly related to C API interactions, demonstrating the effectiveness of Zig's memory safety features in a large, complex project.

Linux ASI Performance Breakthrough: From 70% to 13% I/O Overhead Reduction

2025-08-14

For years, Google engineers have been working on Address Space Isolation (ASI) for the Linux kernel to combat growing CPU speculative execution vulnerabilities. Early implementations resulted in a crippling 70% I/O throughput penalty. Now, that overhead is down to just 13%. Google engineer Brendan Jackman has revived the effort, presenting a solution to the page cache performance issues. While challenges remain, particularly concerning context switching and copy-on-write operations, the significant progress makes ASI a viable contender for a mainstream CPU vulnerability solution.
