HN Discussion: This is literally old news - contemporaneous with Snowden, Prism, etc. in early 2000s. Go read about the current Section 702 / FISA authorization renewal battle about which Senator Wyden recently said Kevin Mitnick also discovered this.. ages ago. Same stuff different day. The United State’s laws do not allow for direct domestic spying or something to that effect so they use Five Eyes anglosphere intelligence alliance marketplace as a loop hole

Less than two months later, Meta ended its contract with Sama, which Sama said would result in 1,108 workers being made redundant.

The current owner Engie are majority-owned by the French government.

The situation is ridiculous and afaik it really didn’t do anything to solve the piracy problem. Genuinely never thought I’d see the day.

Durable queues, streams, pub/sub, and a cron scheduler – inside your SQLite file
Summary: Honker | Honker Skip to content Honker Docs Search Ctrl K Cancel 384 GitHub Select theme Dark Light Auto Honker Durable queues, streams, pub/sub, and a cron scheduler — inside your SQLite file. Read the docs GitHub honker adds Postgres-style NOTIFY / LISTEN semantics to SQLite, with a durable pub/sub, task queue, and event streams on the side, without client polling or a daemon/broker. Cross-process wake latency is ~0.7 ms p50 on an M-series laptop.

Eventually, it was abandoned because Rails itself started going all out on SQLite. https://github.com/oldmoe/litestack It’s an interesting approach and can be quite fun to use for new projects. > How it works: honker polls SQLite’s PRAGMA data_version every millisecond.

He ranks among the top 2% of scientists globally (Stanford/Elsevier 2025) and is one of GitHub’s top 1000 most followed developers. Menu and widgets My home page GitHub profile Your business needs help?
HN Discussion: Daniel Lemire’s points about low-level hardware optimization notwithstanding, it’s worth pointing out that binary search (or low-level implementation variants) is the best only if you know nothing abo The title is slightly misleading, I mean yes, naive binary search might have larger constant but the algorithm is still O(log(n)). This is still some “divide and conquer” style algorithm just with bun Isn’t “quaternary” just sort of unrolling the binary search loop by one level? I mean, to find the partition in which the item is located, you still do roughly the same rough number of comparisons. Yo

When entrepreneurs are I like the networking perspective, but the ML perspective is such a loose analogy that it’s hard to even judge.

(Not to blame the site(s) for such practices, but to think about the whole ecosystem of how a government comes to have a bicycle, US Gov auctions are great when you want 400 of something broken or want to travel through 3 states for a $1000 mil-spec kitchen sink.

This post explores how we can take this paradigm and apply it to a simple date-parsing problem in C++98, C++11, C++17, and finally C++23.
HN Discussion: It seems like the C++98 example is the best by far? Keeps all error information while remaining concise and easy to understand. Not to mention 50 times faster.

A 1960s art school experiment that redefined creativity
Summary:
HN Discussion: Am I right in saying the conclusion of the experiment was: people who spend more time thinking about a problem before acting tend to find it more engaging and were therefore more successful? I wonder I was always told that the difference between art and design is that the artist creates the problem, and the designers solve them. I thought it followed the Socrates tradition in that the true philoso This whole thing strikes me as coming from the wrong direction. Tying artistic and financial success, trying to apply some cargo cult “problem” engineering mentality to art. I feel like these articles

How an Oil Refinery Works

Though wind and solar continue to carve out larger and larger shares of world energy supply, the modern world still runs on petroleum, and will continue to do so for the foreseeable future. The world consumes over 100 million barrels of oil a day.
HN Discussion: Instantly I’m reminded of ” That Time I Tried to Buy an Actual Barrel of Crude Oil ” https://news.ycombinator.com/item?id=43761572 https://archive.is/kLFxg Which leads to ” Planet Money Buys Oil ” htt The article is quick to point out the huge role of oil in the modern energy mix. It also fails to note that most of the energy ends up us waste heat. The so called “Primary energy fallacy”. Other than I find it amazing how “naphtha” can mean crude oil, diesel, kerosene, gasoline or kind of white spirit.
