The March issue of IEEE Spectrum highlights a key issue hindering the adoption of electric vehicles (EVs): the lack of a robust public charging infrastructure. While most charging occurs at home, a significant percentage of drivers, such as those in commercial and residential situations, depend on public charging options, and their experiences can be stressful due to scarcity and reliability issues. A survey revealed that 62% of EV owners have altered their travel plans due to range anxiety. Policymakers are aware of this challenge,

The author reflects on the initial excitement surrounding Java when it was a new programming language with the promise of being a universal platform—“write once, run anywhere.” They recall their enthusiasm for the JavaStation, a soon-to-be-released device that intended to embody this vision. Initially imagined as a stylish coffee pot-like computer, the JavaStation ultimately appeared more like a conventional SPARCstation, and despite its innovative intentions, it did not revolutionize computing as expected. The JavaStation 2 was released

Louis Rossmann, a prominent advocate for the right to repair, expressed his shock and disappointment over Brother's recent shift towards anti-consumer practices in the printer industry. He highlighted two major issues resulting from Brother's firmware updates: the disabling of third-party toner compatibility and the failure of color registration functionality on color devices. Rossmann, who previously recommended Brother printers for their reliability with aftermarket inks, now feels disheartened by their decision to join the ranks of companies restricting consumer choices. He advises users

The writer shares the eighth post in their journey through Sebastian Raschka's book "Build a Large Language Model (from Scratch)." They express that their blogging has included some self-referential topics, partly as a means of procrastination, but they have regained their focus and momentum. In this post, they explore section 3.4, which discusses implementing self-attention with trainable weights in language models. The author aims to explain how a model learns to prioritize certain words in a sentence over

A reader asks whether engineering managers (EMs) should write code in their roles. The author, James, responds that while all managers should engage with the codebase, not all of them need to write code. He emphasizes the importance of understanding the nuances behind coding and management. Using Andy Grove's equation for measuring a manager's impact, James explains that a manager’s effect is based on their team's output and the influence on neighboring teams. He highlights various ways managers can increase their impact, such as

The content discusses the Dead Internet Theory and highlights a related phenomenon where a small percentage of users engage significantly more than others, often referred to as the Power Law, Pareto Principle, or 80-20 Rule. For instance, 10% of Twitter users generate 92% of tweets, illustrating that in various fields—including social media, hobbies, and careers—most contributions come from a minority of participants. This disparity can be observed in competitive gaming, such as in Marvel Rivals, where

In their blog post, Isaac Liao and Albert Gu explore whether lossless information compression can independently lead to intelligent behavior. They build upon previous theories suggesting that efficient information compression is central to intelligence. Their practical demonstration involves a method called CompressARC, which utilizes lossless compression during inference to perform well on the ARC-AGI challenge—an AI benchmark designed to evaluate the ability to infer abstract rules from limited examples. CompressARC adheres to three specific restrictions and achieves performance scores of 34.75

In the winter of 2024, the author restored an IBM PS/1 486-DX2 66Mhz, a computer they had long desired since their teenage years. Upon getting it to boot, they benchmarked it with the game Doom, calculating a framerate of 21.5 fps—decent for a 1993 machine. After discovering fastDOOM, a port that enhanced performance without sacrificing features, they experienced a 30% speed increase, and an even greater

In early March 2025, a Shopify engineer from the Ruby and Rails Infrastructure team reflects on the launch of a new Ruby HTTP server called Pitchfork, which was released over two years prior. The engineer discusses the unique design and trade-offs associated with Pitchfork, contrasting it with Unicorn, the application server long used by Shopify's monolith, which they argue is unfairly labeled as legacy software. The engineer defends Unicorn, asserting that it remains suitable for Shopify's needs, especially given their less

SkyPilot utilizes SQLite for state management due to its capability to handle millions of queries per second and terabytes of data. However, challenges arose when scaling their Managed Jobs feature due to SQLite's limitation on concurrent writers—only one writer can operate at any moment, which is problematic when multiple jobs complete simultaneously. During testing, issues emerged primarily when jobs exceeded 1000 in number, causing errors linked to SQLite’s concurrency constraints. SkyPilot operates with a single instance (the "controller") managing multiple job

James Wilkins discusses procedural generation, a method for creating natural-looking textures and environments using algorithms instead of manual design. This technique is widely used in video games to generate unique landscapes, as exemplified by Minecraft, where each new world is created using procedural methods. At the core of this process is Perlin noise, which provides a smooth randomness that is beneficial for terrain generation. The guide aims to explain how Perlin noise works, how to implement it, and ways to customize it for designing terrains,

The article discusses the challenges of modern software development, likening it to a chef needing to perform every aspect of meal preparation rather than focusing on cooking. It critiques the unrealistic expectations placed on "full-stack developers," who are now expected to possess a wide range of skills, often at the expense of deep expertise. The author notes that while the original idea of a full-stack developer was practical, the current demand for multi-talented programmers has led to burnout and a generation of developers who can do many things

Ruud van Asseldonk is developing a new configuration language called RCL, which is a gradually typed superset of JSON that allows for abstraction and reuse. RCL is designed to generate JSON, YAML, and TOML files, while also serving as a JSON query tool. A significant recent enhancement to RCL is the inclusion of float support, which has presented challenges due to conflicting guiding principles. RCL builds on JSON's number syntax, but the semantics of numbers can vary across different programming

However, translating the site into German revealed challenges due to the numerous terms for "speed bump" and inaccuracies from translation tools. The author compiled a list of the terms and emphasizes the importance of using professional translation services, as cultural context can also impact relevance—speed bumps are unpopular in Germany, with Munich having stopped their installation due to safety concerns.
