Over the past year, a series of interviews with expert tech bloggers focused on sharing insights and advice for new bloggers. The interviewees were asked the same questions, leading to a variety of insightful responses. A recurring theme in their advice for beginners is to write without overthinking it. They suggest writing about personal projects or problems they are passionate about, as this often resonates with readers. New bloggers should focus on regular writing to build their skills, accepting that initial readership may be low. As confidence grows,

A serious issue occurred when all servers in production crashed within 90 seconds due to a single malformed HTTP request causing a segmentation fault in the application. This triggered a chain reaction where the load balancer marked the failed server as unhealthy and retried the same request on subsequent servers, leading to a rapid cascade failure across all servers. Typically, load balancers retry failed requests multiple times (often three), resulting in four total attempts, which exacerbates the problem as each retry targets a different server. In one

A recent Substack post by Skilled Coder on Java data structure performance highlighted significant findings from conducting 10 million operations, particularly regarding insertion and get operations. The post sparked curiosity about how these results compare to Eclipse Collections (EC), which has its origins in 2004 when it was developed by Goldman Sachs due to limitations in JDK's collections. EC offers enhanced functionality and better performance compared to standard JDK collections. Using the Java Microbenchmark Harness (JMH) to run benchmarks, it was

Scheduling background jobs within database transactions can lead to various issues in Rails applications, such as RecordNotFound or ActiveJob::DeserializationError due to jobs executing before a transaction commits. Rails 7.2 introduces a solution with the `enqueue_after_transaction_commit` method, deferring job enqueueing until transaction completion. In practice, scheduling a job, like sending a welcome email after user creation, may function well in development but fail in a production environment with faster job queues, where transactions may not commit

The talk by Severin von Wnuck-Lipinski and Hajo Noerenberg explores the complexity of household appliances, which, despite their common use, often lack detailed public documentation on their internal workings and communication protocols. It examines proprietary bus systems, diagnostic interfaces, and the integration of appliances from two manufacturers into home automation systems without relying on cloud solutions. The presentation highlights challenges in reverse-engineering these devices, including analyzing control boards and communication buses, as well as modifying firmware for better functionality insights

On December 12, 2025, MongoDB's Security Engineering team discovered a vulnerability known as CVE-2025-14847, informally referred to as “Mongobleed,” affecting MongoDB Server. The company emphasizes that this is not a breach of its systems or MongoDB Atlas. The blog post details their response to the vulnerability and highlights the importance of ongoing security responsibilities in software development, focusing on trust through effective issue identification, resolution, and communication.

The InnoDB Storage Engine uses a specialized variant of the Least Recently Used (LRU) eviction algorithm to manage its cache, which consists of both on-disk structures (like tablespaces, redo logs, and undo logs) and in-memory structures (specifically the buffer pool). The buffer pool caches frequently accessed table and index pages in RAM to improve query processing speed, often utilizing up to 80% of a dedicated database server's physical memory. InnoDB enhances traditional LRU management by

The content emphasizes the importance of user feedback and highlights the features of Ensue, a platform designed to enhance interactions with a language model (LLM). Unlike typical LLMs that begin each conversation without memory of previous ones, Ensue serves as a persistent knowledge tree, retaining accumulated knowledge to enrich future discussions. This allows the LLM to reference past information and decisions, facilitating more informed conversations. The platform includes various resources such as documentation and API access. There are also frequent error messages suggesting issues with

At RailsWorld, the speaker was prompted by a question about why Bundler can't match the speed of the uv package manager, which sparked their curiosity and led to further investigation into Bundler's performance. They believe that Bundler can achieve similar speeds to uv, albeit with some limitations. The speaker references a post by Andrew Nesbitt titled "How uv got so fast," aiming to explore the techniques used in uv and how they could potentially apply to Bundler/RubyGems, while identifying existing

Battlecode is a real-time strategy game where participants code an autonomous player to manage a robot army and compete against other teams. Contestants utilize artificial intelligence, pathfinding, distributed algorithms, and communication strategies while dealing with limited computation per turn. Teams receive the game software and rules in early January to refine their players and compete in scrimmages and tournaments, culminating in a live-streamed Final Tournament at MIT with over $20,000 in prizes and merchandise for attendees. The top college team can also

At the 39th Chaos Communication Congress, security researchers Lexi Groves and Liam Wachter revealed 14 vulnerabilities across four programs involved in data encryption and signing, including GnuPG, a well-established PGP implementation. These vulnerabilities stem from implementation errors rather than flaws in the underlying security methods. Notably, issues in GnuPG included problems with handling C strings, leading to false validation of signatures and the potential for attackers to manipulate data without detection. The vulnerabilities could mislead users into executing

Rails 8.2 introduces a unified API called Rails.app.creds for managing application secrets, streamlining the process of accessing credentials stored in environment variables and encrypted credential files. Traditionally, migrating between these storage methods required code changes, but this new feature allows for seamless management without altering application code. Key features of Rails.app.creds include: - A consistent interface that defaults to checking environment variables (ENV) first before falling back to encrypted credentials. - The `require` method raises a KeyError

The content discusses the evolution and significance of the robots.txt file, which has been a fundamental tool for managing web crawler behavior for the past three decades. This simple text file allows website owners to control who can access and index their content, reflecting a mutual agreement among early internet users to respect each other's rights. However, the rise of AI companies has disrupted this arrangement, as they increasingly exploit website data to create large training datasets for their models, often without recognizing the original sources. This shift threatens the foundational
