The author reflects on their 20 years in software development, sharing personal anecdotes that emphasize the human aspect of the journey rather than providing lessons. They begin by recalling their early exposure to programming and their serious engagement with software development upon entering university around 25 years ago. One of the key stories takes place in 2001 when they visited a university computer lab and stumbled upon the website susam.com. A fellow student approached them and demonstrated how websites are created using HTML, which sparked the author’s curiosity

The content discusses the internals of Redis/Valkey replication, particularly focusing on a bug related to the KEEPTTL command which can lead to data inconsistency between the master and replica nodes. When a hash key with a set TTL is overwritten using KEEPTTL on the master node, the same command is executed on the replica. However, if there is a network delay causing commands to execute out of order, the replica may end up with an expired key without a TTL, leading to

In the realm of Large Language Model (LLM) security, a new challenge called Token Smuggling has emerged, where attackers bypass security filters designed to catch harmful inputs. These filters function similarly to bouncers who check for specific banned phrases, such as "DROP TABLE" or hate speech. Token Smuggling cleverly disguises these prohibited concepts, making them unrecognizable to the filter while remaining comprehensible to the LLM. The technique takes advantage of a critical gap in how filters process text versus

OpenTelemetry (OTel) baggage is a mechanism that allows the transmission of "global" metadata, such as customer IDs or feature flags, across various services in a distributed system. Unlike traditional tracing that captures information specific to individual spans, baggage facilitates the propagation of arbitrary metadata throughout the system, enabling consistent context sharing. This write-up details how baggage resolves the issue of "parameter drilling" and enhances application behavior during requests. It functions as an established observability signal alongside traces, metrics, and logs,

The content is a catalog highlighting the atomic operations provided by UNIX-like/POSIX-compliant operating systems, useful for developing thread-safe and multi-process-safe programs without the need for mutexes or read/write locks. It emphasizes the importance of allowing the kernel to handle operations efficiently, rather than using CPU time on unnecessary locking when an operation is already atomic. The author notes that these operations are best applied to local filesystems, as they may not work correctly with NFS mounts due to multiple kernels. The

The author attempted to delete their Tower of Fantasy account from over four years ago but struggled to find a way to do so without reinstalling the game, which is over 100 GB in size. While waiting for the lengthy download, they explored the launcher directory and discovered a kernel driver, GameDriverX64.sys. They noted that while anti-cheat drivers are meant to protect games by operating with high privileges, poorly written drivers can pose security risks, as they can become attack surfaces that could compromise the

Sergey Tselovalnikov highlights the evolving role of Quality Assurance (QA) in software development, emphasizing its increasing centrality compared to merely building software. Over the past year, he has noticed a shift in his approach to code changes, where he now prioritizes how to test functionality rather than focusing solely on creating a working prototype. He notes that the effectiveness of coding agents relies significantly on their ability to verify their outputs, a process that can often lead to presenting incorrect or incomplete code. While coding

Nicholas Carlini, a researcher on the Safeguards team, shares insights from an experiment with "agent teams," which consist of multiple Claude instances working on a shared coding project without human intervention. He tasked 16 agents with creating a Rust-based C compiler capable of compiling the Linux kernel, resulting in a 100,000-line compiler after extensive sessions and significant costs. Carlini highlights the challenges of programming autonomous agents, emphasizing the need for effective testing and work structuring to maintain continuous progress without

Postman recently announced significant updates in March 2026, marking a dramatic evolution from its original role as a simple API testing and documentation tool to a complex cloud-based platform. The changes reflect a trend towards feature bloat, resulting in a product that increasingly integrates numerous capabilities, potentially leading to vendor lock-in for users. Notably, Postman aims to transform into an all-in-one platform for building and deploying AI-powered APIs. Key new features include: 1. A visual “Agent” block system

The blog post discusses the benefits of running your own data center rather than relying on cloud providers for compute needs. The author highlights that managing a personal data center fosters self-reliance and better engineering practices by focusing on real-world challenges instead of complex cloud billing and APIs. It also provides incentives for engineers to improve efficiency since additional compute power isn't just a budget increase away. Furthermore, operating your own data center can be more cost-effective, especially for consistent compute or storage requirements common in machine learning. The
