Buying a home or refinancing a mortgage can be complicated, especially with confusing advertisements from banks and large lenders. Credit unions, being member-owned and non-profit, often provide competitive rates but lack extensive marketing budgets, making their rates harder to compare. To assist consumers, a daily-updated comparison of mortgage rates from over 120 credit unions across the U.S. has been created. It highlights how a local credit union offered a significantly lower APR than a big bank for the same mortgage, demonstrating that different institutions

Japanese game developers are facing a significant problem due to a sharp increase in font licensing costs. Fontworks LETS, a major font licensing service, has replaced its annual plan, which used to cost around $380, with a new plan priced at $20,500. This replacement plan does not offer local pricing for Japanese developers and imposes a cap of 25,000 users, which is insufficient for larger studios. Additionally, the challenge of finding fonts that accurately represent Kanji and Katakana complic

The author proposes a theory that the psychological concept of "imprinting," where young animals form attachments to their first moving encounter, can also apply to programmers and their initial programming languages. Many novice programmers feel a strong connection to Ruby, which is often seen as a language that makes programming truly resonate. The author, who first learned programming with Java and later found a deeper connection with JavaScript and OCaml, shared their experience of learning Ruby later in their career. Unlike the early enthusiasts, they viewed Ruby

AI companies are heavily investing in data centers as they pursue artificial general intelligence (AGI), but concerns about the financial viability of these investments are growing. IBM CEO Arvind Krishna noted on the "Decoder" podcast that it's unlikely these companies will recoup their capital expenditures (capex) on data centers. He mentioned that constructing a data center with one gigawatt capacity costs about $80 billion. Therefore, if a company commits to building 20 to 30 gigawatts, the costs could

Bun has been acquired by Anthropic, which intends to use Bun as the infrastructure for its AI coding products, including Claude Code and Claude Agent SDK. If Bun encounters issues, it would directly affect these products, creating an incentive for Anthropic to maintain its quality. The creator of Bun began the project out of frustration with slow development cycles while building a browser-based voxel game. He initially worked on porting esbuild's JSX and TypeScript transpiler, achieving significant speed improvements over existing tools.

The content discusses the transition from parsing syntax into a Concrete Syntax Tree (CST) to the next step of desugaring, which involves removing syntactic sugar and mapping the CST onto an Abstract Syntax Tree (AST). Desugaring helps eliminate unnecessary syntax (like | or =) from the compiler's focus, making it easier for later passes by emphasizing what's semantically important. While it may seem cumbersome, using separate ASTs is beneficial, especially because certain constructs like let expressions are not represented in the

Keeping documentation up to date is challenging, especially when product changes affect multiple sections, such as screenshots. Outdated screenshots are a common issue because not all changes prompt corresponding documentation updates. To mitigate this, it is beneficial to automate screenshot updates. By setting up automatic generation of screenshots, users can quickly update documentation to reflect changes in the application's appearance with a single command. Automating screenshot generation is similar to automating tests, as both aim to identify and rectify issues before they reach end-users. While Ub
