Service reliability is commonly represented as a percentage, such as 99.9% uptime, which suggests approximately 8 hours and 46 minutes of downtime per year. However, this simplistic view ignores important nuances that engineers must consider. Notably, the nature and timing of downtime matter significantly; for example, one 8-hour outage can have different business impacts than multiple short outages, and downtime during peak hours can be far more costly than during off-hours. Additionally, achieving higher reliability often requires exponentially more

Git's autocorrect feature intentionally waits 0.1 seconds before executing a mistyped command, like "git pushy," allowing users to verify the intended command. This functionality, which has surprised users like @dhh, emerged from a combination of misunderstandings and historical decisions made by Git maintainers. It was not always a default behavior; initially, typing an unknown command produced a simple error message. In 2008, a patch was introduced to suggest similar commands, and subsequently, an option

The author discusses the importance of Virtual Private Clouds (VPCs) in Amazon Web Services (AWS) and their role in networking. Understanding VPCs is essential for grasping other AWS networking concepts. The motivation behind the creation of VPCs stems from challenges faced by companies considering a move to AWS, particularly concerns about shared networks where users might access each other's instances, and the potential for IP address conflicts with existing servers. The author provides a personal anecdote, stating they run a business called

In his article "Back Home," Josef Chen highlights the stark contrast in career trajectories for hardware engineering graduates from top UK universities like Imperial, Oxford, and Cambridge compared to their counterparts in Silicon Valley. While London graduates start with salaries between £30,000-£50,000, those in Silicon Valley can earn over $150,000. Many graduates are forced to accept lower-paying roles or switch to more lucrative fields like consulting or finance, leading to a significant waste of talent. Chen presents examples of

The article discusses the evolution of home technology from a tool promoting personal freedom to one associated with corporate control and surveillance. In the early days of personal computing, individuals experienced a sense of tech liberty, having ownership and control over their devices. However, in recent years, the rise of internet surveillance, algorithmic bias in social media, and restrictive digital rights management (DRM) practices have shifted that control to large corporations. These changes have eroded the freedoms originally promised by personal computers. The author emphasizes

The content discusses the impact of interruptions on software engineers' productivity and stress, highlighting research findings on how different types of interruptions—like coworker questions and notifications—affect their work. It emphasizes that not all interruptions are equally disruptive, as factors like urgency and the authority of the interrupter play a role. The shift to remote work has changed the nature of interruptions, making it essential to understand their effects on engineers’ performance in tasks such as code writing, comprehension, and review. A study by

The author embarked on a project to create their own Kafka Broker, MonKafka, which led them to explore the topic of compression, particularly for Kafka's record batches. Kafka currently supports four compression algorithms: GZIP, Snappy, LZ4, and ZSTD. Realizing their limited knowledge of compression beyond the basics from school, the author decided to delve deeper into the various compression algorithms. Compression is key to reducing storage requirements and transmission times by representing data with fewer bits, resulting in significant

Ruby's JSON library can convert native Ruby data types (String, bool, int, float, nil, Hash, and Array) into JSON. Non-native types, such as Range, Symbol, and Time, default to String during JSON serialization. A recent feature allows serialization of most core data types by requiring the `json/add/core` extension and using the `create_additions` keyword. This method has minimal performance overhead but does not resolve issues with Symbol hash keys, which remain a challenge for Side

The content discusses the challenges of indentation in Lisp code, particularly focusing on how to manage parentheses and readability. While Lisp programmers tend to rely on indentation once they become accustomed to the syntax, there are alternative indentation-based syntaxes like Wisp and sweet expressions. The text highlights the problem of long lines of code being unreadable and the necessity for multi-line formatting with appropriate indentation. A common indentation style is presented, which aligns function arguments vertically to improve code structure visibility. However, this style can become cumbersome

The discussion revolves around the differences between Redis commands UNLINK and DEL. Most people believe that DEL is blocking while UNLINK is non-blocking, making UNLINK the preferable option. However, the author argues that this characterization is an oversimplification. Both commands aim to remove keys from Redis, but they differ in their memory deallocation techniques. UNLINK intelligently decides whether to free an object immediately (like DEL) or send it to a background queue for later processing, based on the deallocation
