The content discusses concerns over online privacy, particularly for individuals interested in "de-Googling," or distancing themselves from Google and its services. A key concern is preventing web browsing behavior from being shared across organizations, as personal information could potentially be misused by entities like medical insurers or advertisers. The author notes that while moving away from Google is a vital first step in protecting privacy, further actions are necessary, especially due to the rise of browser fingerprinting, which complicates privacy efforts. Previously, the

The article discusses the author's experiences with data races in Go, highlighting both the language's strengths in concurrency and its pitfalls. While Go makes it easy to write concurrent programs, it also poses risks of data races, which occur when code does not align with the Go memory model. These races can lead to serious issues like inconsistent values and arbitrary memory corruption. The author shares real examples of data races they have encountered and fixed, and they offer recommendations on how to avoid such issues. The piece serves as a

The blog post delves into the intricacies of DNS and name-to-IP translation, examining components like NSS, getaddrinfo, and systemd-resolved. It begins with a discussion of a recent internet disruption that, contrary to initial beliefs, was not caused by DNS issues, but rather a malfunction stemming from an oversized configuration file. This incident led to disappointment among those who joked about DNS always being the problem. The author emphasizes that name resolution goes beyond just DNS, highlighting the importance of various methods

The author expresses deep regret for failing in their responsibilities and disappointing colleagues after 15 years of work. They describe the inefficiencies in their team's processes, particularly concerning server access, which has forced them to rely on cumbersome manual methods for testing and deployment. Although they have traditionally upheld DevOps principles to avoid manual deployments, frustration led them to implement a workaround using a Python script to automate file handling. Despite recognizing this as a less desirable solution, they find it effective. The author concludes with an apology,

The content discusses Lite³, a JSON-compatible zero-copy serialization format that encodes data in a B-tree structure, allowing for direct mutations on the serialized form. It eliminates the need for traditional parsing or serialization processes, enabling efficient access with O(log n) time. Lite³ is schemaless and self-describing, supporting seamless conversion to/from JSON for compatibility with existing datasets and APIs, making debugging easier. The document also briefly mentions examples of using Lite³, including an alternative 'Context API'

Multithreaded programming provides advantages such as increased speed and efficiency by utilizing all CPU cores. However, it introduces challenges related to shared memory, particularly race conditions, which occur when multiple threads access the same data simultaneously, leading to unpredictable outcomes. Mutexes are used to manage access to shared resources, ensuring that only one thread can access a resource at a time, thus preventing negative side effects. A race condition happens when the program's result relies on the timing of thread execution, resulting in non-d
