lefty2··on macOS 15.8.2 Breaks OpenGL
interesting story, but the fact that Apple and Nvidia were sueing each other doesn't seem any reason to drop all open standards. I would say they did it because of arrogance - ie. we're Apple and everything we do is better, therefore our graphics API is superior than any other

> they claim that two of those three quarters were profitable.

no they didn't. What they said was "positive adjusted operating income". The most important word there is "adjusted", ie. they are not profitable if you include all costs

Also, bear in mind the guy who wrote the article lives in the same flat as Sholto Douglas, an Anthropic researcher.

Interesting fact, you only could come third in the Olympics during the bronze age
lefty2··on ChatGPT Images 2.5
Even GPT Images 2.0 was already the best image generator that I have tried, however it has one massive disadvantage: draconian censorship. Even rendering a gun in a scene will get flagged as "violent" and I need to create a battle scene... there's no way to do that with the censorship the way it is

The first version is already beating Rubin in the benchmarks, according to SemiAnalysis
lefty2··on Nvidia Insists It Can Keep Printing Money to Fund the AI Boom
So, Nvidia are backstopping $100B for the Ohio project, yet at the same time OpenAI are developing their Jalapeño processor, which will mean it will no longer need Nvidia GPUs for inference. That does not really make any sense to me.
lefty2··on Why Wall Street is ignoring big tech's debt [video]
> Even Deepseek at its absurd prices is a very healthy business. Regarding their return on capex multiple, their CEO said they make a six-fold profit on their compute capex with 10 month recuperation.

That's "theoretical profit" - in some imaginary world where the free subscribers would pay the top tier cost.

Don't worry, if it escapes from the lab we can just blame it on the bats again

I understand now. Flagged means inappropiate for Hacker News. Yeah, they always flag any article that is anti-AI - even if it is well reasoned

flagged as what?
lefty2··on AI's debt binge can't last, hidden borrowing reaches $1.65T
> I literally do not write code anymore.

but you are taking advantage of a subsidised service. What happens when developers are forced to pay the full price (i.e. $2000 a month instead of $200 a month)

yes, but not necessarily cheaper
lefty2··on Corporate America Has Suddenly Decided to Stop Blowing Money on AI
The Chinese models are only temporarily cheaper, because they are subsidised the same way that frontier models are. Once those companies need to make money the subsidy will disappear.

According to the article they don't have to declare leases or GPUs until the datacenter becomes operational
lefty2··on A C++ implementation of a fast hash map and hash set using hopscotch hashing
I tried both unordered_flat_map and hopscotch map with the pathfinding algorithm that my game uses. Both were slower than regular unordered_map. unordered_flat_map about 33% slower and hopscotch was 390% slower

They would be jamming their own glide bombs and drones then. It would be more useful to jam Russian airspace to defeat Ukrainian drone attacks.

That will only happen when the bubble bursts and those companies will exit by going bankrupt

lefty2··on Mozilla Used Anthropic's Mythos to Find and Fix 271 Bugs in Firefox
I wonder how many false positives there were. Typically this types of static analysis tools come up with a ton of potential bugs, but only a few of them are actual bugs.

lefty2··on The OpenAI graveyard: All the deals and products that haven't happened
Sora was losing 15M a day and it was running at least 3 months, so that's a total 1.3 Billion. That's a pretty expensive experiment. It sounds like a company with lots of VC to burn and no discipline. Even Jensen Huang accused them of lack of discipline in business approach.

also they need to pay back that in one year, so if OpenAI don't IPO this year they are screwed

You need to be careful, because this doesn't work if the value is negative. A

OpenAI actually burnt $12B in just one quarter (not for the entire year as he claims)

lefty2··on C++ std::move doesn't move anything: A deep dive into Value Categories
c++ 03 was a lot easier.

For instance, if you want to avoid unnecessary copy operations when returning a string, just return it in variable that you pass by reference (eg. void doSomething(string& str);) likewise avoid the vector class making unnecessary copies, simply by creating the objects on the heap and use a vector of pointers instead of values. It's a bit more ugly, but it works, and you don't need to read a 24 page blog to understand all the corner cases where it can go wrong. modern c++ is all about syntactic suger.
