The author shared a small Python program called Mark V. Shaney Junior, which is a minimal implementation of a Markov text generator inspired by the original Mark V. Shaney from the 1980s. The program consists of about 30 lines of code, focusing on simplicity rather than efficiency. The author engages in exploratory programming as a hobby, often creating tiny programs for recreation and experimentation, particularly with Markov chains. Occasionally, they refine one of these programs and share it on GitHub and

The content discusses the concepts of memory safety and sandboxing, highlighting that they are distinct yet complementary. Memory safety ensures that a program does not access memory in an unsafe manner, while sandboxing restricts a program's capabilities to prevent it from performing dangerous operations. It provides examples illustrating that a program can be memory safe but not sandboxed (as in a pure Java program that can overwrite files) and sandboxed but not memory safe (like an assembly program that can only compute but has memory safety

In a 2017 piece, the author discussed a technique for creating closures in C using JIT-compiled wrappers, although he noted that it’s rarely needed in practical applications. He initially applied this technique to the `qsort` function, which lacks a context pointer. Recently, he revisited the concept, contemplating improvements, particularly in enhancing Win32 window procedure callbacks by adding a fifth argument for additional context. While using w64devkit on x64, the author intends for the method to

On Thanksgiving morning, the author discovered that their web service was down, receiving a "503 Service unavailable" error and a cryptic "Runtime version: Error" message. Rather than spend time troubleshooting or contacting support, they noticed a warning about migrating their app from Linux Consumption to Flex Consumption due to the former's impending end of life in September 2028. Having been aware of this issue for weeks while setting up a new app, the realization of a critical error prompted the author to take action and

The author expresses their enthusiasm for exploring the "lost lists" of Anthony Bourdain, inspired by Greg TeChnoLogY's recent work. They aim to recover these lists using publicly available web archives due to their background in security and crawling, despite lacking access to proprietary storage. The author references their development of a script, `commoncrawl_search.py`, which fetches data from the Common Crawl to search for Bourdain's lists. They highlight collaboration with Claude and outline a method for retrieving

A recent analysis by IPinfo examined 20 popular VPNs, revealing that 17 of them route traffic from different countries than they advertise. Many providers exaggerate the number of countries they support, often pointing to a limited number of data centers in the US or Europe. The analysis, which looked at over 150,000 exit IPs across 137 countries, compared the claimed capabilities of each VPN with actual data, highlighting significant discrepancies. The report includes a detailed examination of the countries claimed by each

The author shares their experience with Advent of Code, a coding challenge they participate in annually for seven years, successfully earning all possible stars. They appreciate the time pressure, community aspect, and the opportunity to dive deep into a chosen programming language each December, selecting Gleam this year. This year's event was condensed to 12 days with 24 parts, making it feel more challenging than expected. The easier puzzles were more engaging than prior years, while the harder ones, particularly the last three, presented

The article discusses the engineering behind quantitative finance, specifically focusing on the technology and systems used by exchanges to manage order processing effectively. In a landscape where thousands of orders arrive every millisecond from various global participants, such as high-frequency trading firms and pension funds, it is crucial that all parties have a consistent view of the order sequence. This is achieved through the use of distributed logs for order books, which ensures fairness and a deterministic timeline of events. The process is complex due to the unpredictable nature of order

The article discusses the challenges faced while building simob, an open-source server monitoring agent designed for the Simple Observability platform. The initial goal was to create a single, portable Go binary that could run on any Linux distribution without the need for external dependencies. Simob is envisioned as a lightweight passive sensor rather than a long-running daemon, aiming for ease of compilation and deployment across different systems. Go is chosen for its strengths in observability tools due to its compilation capabilities, garbage collection, and efficient management

The payment service experienced a complete outage due to a circular dependency that went unnoticed. A quick feature added by one team created a deadlock involving multiple services: the user-service, order-service, and inventory-service. Under low load, the system functioned, but during high traffic events like Black Friday, this circular dependency caused all threads to block, leading to a failure. The issue is exacerbated by the fact that systems can appear architecturally sound on the surface without reflecting the hidden complexities introduced

In recent days, the author completed work on the UringMachine fiber scheduler, ensuring it is feature complete with all necessary hooks and behaviors implemented. They dedicated time to writing test cases for both the fiber scheduler and UringMachine's low-level API, as well as benchmarks to compare UringMachine's performance with other concurrency solutions. The results suggest that using the Fiber Scheduler can significantly enhance concurrent Ruby applications with minimal code modifications, such as replacing `Thread.new` with `Fiber.schedule`. The scheduler's

Miguel Ojeda led a session discussing recent developments in integrating Rust into the Linux kernel. Highlights include the upcoming Nova driver for NVIDIA GPUs, the merging of the Android binder driver for version 6.18, and the significant milestone of millions of devices running Android 16 on the 6.12 kernel, which includes a Rust-written ashmem module. The Debian project has enabled Rust support in its kernel builds for the next "forky" release, contributing to a rapid increase in Rust code

The text references previous articles about the challenges of email encryption, highlighting the little progress made since 1998. Encrypting email in both 1998 and 2025 involves similar steps with tools like GnuPG, but the situation has arguably deteriorated, particularly as web-based email has grown in popularity, which often lacks native PGP support. S/MIME, standardized around the same time as PGP, is more widely used in enterprises due to its hierarchical PKI trust model and better client
