I don’t get what’s the point of non-profits if you can IPO them. How does that make any sense?

Why not finance a more wide tax break for tech companies, including small companies? I have seen first hand, one of my classmates from high-school, whom I didn't consider to be too…

Same here, paying for Pro but I just get redirected to vanilla version...

A rare game where having worse PC actually made you perform better. It was easier to time the jump perfectly. I recall starting 5 instances of it to slow it down as a kid and beati…

And Mahomes wouldn’t last a 3 minute round with a boxer.

Calling American football “one of the most competetive sports on Earth” feels like a stretch. It’s big in US, but not that popular anywhere else.

No, Haswell's PAUSE is 9 cycles, the P-cores of Alder Lake are 160 cycles. Zen 4 is 65.

It differs by CPU model.

Jakub Pachocki from OpenAI is polish too.

It's an example of how trivial some of this low hanging fruit is, the above is a concrete case that I have personally implemented (arithmetic of in-register 64/32-bit integers). Yo…

This is an assumption that a reasonable person naively comes up with. Then if you actually go ahead and check, it turns out it's not true! It's quite a shocking revelation. When yo…

The nice thing about compiler optimizations is that you can improve performance of existing CPU's without physically touching them. Year by year. You squeeze more of the machine so…

You can shrink it further by doing xorl reg, reg. On x86, the upper 32 bits are cleared for you when using 32 bit opcodes. No need to do a 64-bit reg, reg xor. Instead of doing cmp…

There doesn't seem to be a good in-depth academic resource for advanced compiler optimization. I've searched a lot and all the courses I found were introductory, the actual interes…

As if he wasn't playing with the prototypes daily before the launch. Maybe he should step down instead. How about that? Nah, the money and prestige is too good. Better compose a PR…

This might sound harsh, but: Maybe the wise choice is to change the path? That feeling of resignation, while a bitter pill to swallow, might be a good thing in the end. I used to b…

Yes, I copy pasted it (How many legs do ten elephants have, if two of them are legless?).

ChatGPT 4: Ten elephants would have a total of 32 legs if two of them are legless. Analysis: # Calculating the total number of legs for ten elephants, considering two of them are l…

A large SAD light therapy light (beurer). Fixes my insomnia. Bonus points for acting as a webcam light.

What are they using to benchmark single-threaded performance? I don't think it's good to state that without clarifying what is the task being run. You could have a benchmark that i…
