The reason genAI is cheap and unlimited right now is because it is heavily subsidized by blind and reckless investing… As a business venture it is vastly unprofitable compared to the energy it costs and once the bubble pops the landscape will change

? It's literally like, 19 bucks for unlimited image gen, lol. Nice cope though. Here, my first pass at Nano Banana Pro without knowing what I was doing, and keep in mind, this is going to be the floor of what it can do in like, 3 months, let it cook.

Calling it now: There will be no consequences for the creators of the AI bubble that is about to take down the US economy. The main culprits will be made whole by the taxpayer, and the gullible fools in media who promoted the bogus tech will remain in cushy positions of influence

That’s actually the perfect use of generational wealth

Privilege is having rich parents who set you up for life so that you can spend your entire youth doing useless activism while never worrying about having a real job.

I hate AI with a passion. It’s an unregulated, unconsidered, human-ingenuity-wrecking, resource-sucking, climate-destroying theft-machine being pushed by short-sighted, greedy individuals putting product and profit over people and planet. But it turns out… I can hate it more.

wrote the same word-counting program 5 times, each faster than the last best result: 494× faster than my first Python version — by using SIMD in C all are O(n), but some squeeze far more from the CPU and memory!

Sometimes servers don't send HTTP response data in the right order. Our new article explains why request priority matters for HTTP/2 and HTTP/3 connections, and how poor server-side support can impact page speed. debugbear.com/blog/http-prio…

Please stop building SPAs. Just because your pages all have the same header and footer, it does not mean you have a single page app. Over 90% of the SPA projects I’ve worked on should not have been SPAs (and were markedly worse because of it).

The Big Short stays wildly rewatchable. Fast, furious, and somehow makes finance thrilling—stacked cast firing on all cylinders.

Highly recommended read on how complex networking is when designing a game.

Okay, so, like, here's a very *high level* overview of the issues involved in doing a networked game at a decent level of quality. The first thing one discovers when doing this kind of system is that, even though web dudes love TCP, it is very bad for games if that's all you…
