It depends. If your target is x86/x86_64 and the compiler has a LLVM or Intel backend, I've found that beating the compiler is almost impossible and largely futile. I took a long time to accept this since I know asm and the x86 in

I liked most interviews, but the one that irks me are when the interviewer asks very specific questions that are specific to the particular domain the company is in. But one of the biggest reason to apply somewhere as a developer is precise

Hi, and thanks for your interesting work. Isn't the quality of the prediction heavily influenced by how common the encoded content is?

> practically speaking nearly everyone is moving on to HEVC. Nearly all the other competitors are in development and unusable because of their really slow encoding time. Be careful when saying the truth!

It's a debt decision, the difficulty of creating the code is relatively small compared to the everlasting cost of maintaining it afterwards. Also, managing the dependencies whims also is debt.

It think the point of the article is that with SaaS, the customer invariably end up spending more than she really wanted vs purchased locally-hosted software. Which is a big reason why there is so much SaaS in the first place, in both the c

Carbon tax is not harder to implement than VAT. It's also the most effective tool against CO2 release.

Does this happen in practice or the old product is just replaced by a newer _competitor_?

I just hate the "fun" jokes in Discord at start-up. I'm in 4 servers and none of them are about video gaming. It is a great chat application fit for many more purposes. Discord is great for business!

In countries where VAT tax exist, the whole chain of value pay a fraction of the added value they produce. It works with a differential between the VAT you bought vs the VAR you charged. Why wouldn't we don't adopt a similar syste

D can be used for almost everything: this is indeed a marketing message that is harder to pass than "Language X is made for problem Y". For example I do signal processing, and D is surprinsingly pleasant for it since it has builti

Interesting! Now I'm interested if there has been one usage case for the single bit spinlock in practice. It seems appropriate if writes aren't too numerous (well leaving aside speed concerns). Or a case where std::mutex was too l

Mmmm... I had to write this down. 0: CAS_bit_n(void* adr, int n) 1: while(true): 2: old <- read unit(adr) 3: new <- compute-new-value-with-changed-bit-n(old, n) 4: if CAS(adr, old, new): 5: break

That doesn't work since this isn't atomic anymore.

That's why tricle down carbon tax is a right answer.

Honestly I'm not so sure about the case for spinning; in x264 source you can see CRITICAL_SECTION is tuned to have a spincount of 0. This is a very optimized, multi-threaded app. They didnt want any spinning. https://github.

A typical mutex has essentially two very different costs depending on whether the lock is already taken by another thread: - Uncontended case + mutex: no syscall, fast path is basically the cost of the memory barrier. - Uncontended case + s
