Caching is an abstraction, not an optimization

June 30, 2025 Caching is an Abstraction, not an Optimization I've always been told that caching is a tool to make software faster. That, given some careful considerations to consistency, caching makes it so that when you want to read a given piece of data, you don't have to go all the way back to some backend database or API server or SSD and can instead just read from some faster location like memory for the same data.

Flounder Mode – Kevin Kelly on a different way to do great work

news.ycombinator.com Brie Wolfson 2025-08-14 02:18:01

Kevin Kelly isn’t known for one ‘big thing’, and doesn’t aspire to be. He’s as intelligent, hard-working, ambitious, and prescient as history’s most iconic entrepreneurs—only without any interest in building a unicorn himself. Instead, in his words, he works “Hollywood style”—in a series of creative projects. What follows is a sampling of his life’s work. Kelly was an editor for the Whole Earth Catalog in the early 1980s, helped start WELL, one of the first online communities, in 1985, and co-f

Bitcoin Whales Are Offloading Their Bags on Institutional Investors

gizmodo.com Matt Novak 2025-08-14 15:10:13

Bitcoin enthusiasts have been perplexed lately. Why is the price so stagnant, even with all the hype created by guys like President Donald Trump? The White House has largely been seen as enacting a pro-crypto agenda and even got its first crypto czar in David Sacks, after all. You’d think prices would be soaring. Well, there’s a simple answer, according to a new report from Bloomberg News. And the average, non-wealthy crypto trader probably isn’t going to like it. According to Bloomberg, the lo

I’d like to share the process of porting the original codebase from ~67,000 lines of C code to ~81,000 lines of Rust (excluding comments and empty lines).

5 reasons why Google’s Pixel software is better than Samsung’s One UI

Silicon Valley Bank’s collapse in 2023 left a hole in the tech industry. For years, the bank poured money into the Bay Area’s riskier startups, allowing those companies to pursue their various “disruptive” aims. Eventually, mismanagement led that business model to collapse.

Let’s be honest: A crowded airport lounge without a seat in sight is usually less appealing than an empty gate area.
