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 bright, receive a 100k EUR grant to build an esports p

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 beating records. Fun times.

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.

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). You can get into semantics and restrictions, but I t

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 you dig into the popular compilers/runtimes (wi

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 someone designed. It adds up. Imagine what environmental

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 $0, %eax, you can use test eax, eax - that's another l

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 interesting techniques require diving deep into the sourc

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 piece to control the damage.

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 beat myself over for not working hard and dedicating myself t

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 increments a number in register. Since add/in

Because the temporal factor is the hardest one to game. Thus a strong predictor of quality/spaminness. Spammers used to do churn and burn and rank in a month or so. This has been killed mid 2013.

Use distilled water. I bought a distilling machine just for this and my pm2.5 sensor barely moves. Used to peak up to 120 on tap water. Now it’s consistently under 2 and the air is humid.

It's a very useful instruction. Go uses it extensively in its core runtime and the compiler itself. I assume other languages do too if they care about performance. Examples: 1. Growing a slice. 2. Runtime's heap bitmap. 3. Page al
