You can contribute to open source compilers. It’s both fun and beneficial.

The primary reason is to make Intel CPU's more competitive compared to ARM. It's not all about the silicon. The compilers and OS code can affect performance in big ways.

Just use self hosted OpenSearch. It’ll save your company millions anually if you are large enough.

I have removed signed-integer based values bounds checking in a compiler once and before I noticed, I got a nice 3.8% performance gain in a large diverse benchmarking suite. While not expensive, bounds checks are certainly not free.

Yes, it’s 1 cycle but it’s longer to decode and occupies more of l1i cache. It’s not all about execution cycles.

You can use the 32bit xor to reset the register. Also TEST REG,REG might be better for checking if it’s zero.

Can you show any examples of "go compiler being garbage"? In my experience, it often generates much smarter code than C# or Java.

Please refrain from making those misleading statements. One can easily prove you wrong by disabling constant hoisting and CSE and showing it significantly slows down practical code(JSON parsing, gzip). I actually worked on CSE today and had

The “branch” looks like an easy cmove target. Moreover, while it might not have a branch in the func itself, you will have to have one somewhere higher in the control flow anyway. As for loop unrolling, I bet you a loop with unrolled calls

DRY is better for performance (cache efficiency). It’s also less work for the compiler. Those might not be concerns of someone writing pizza CRUD in python.

This should have been done way earlier. WHO's excuse of not declaring it before was that it didn't reach Antarctica yet... which is ridiculous. Had they raised alarm early on, more countries would have enforced proper procedures (

I believe there are some solutions to help alleviate the situation. Introduce land value tax. In the countries using it, stop the mandatory Ponzi scheme retirement pyramid where young people are forced to pay a sizeable part of their payche

You need to hire people who are competent with a new, quickly evolving technology. That means it's hard to hire someone good and it's expensive. The upside is that you can replace multiple "normal" ops people with just a

OpenStack is used mostly for the layer beneath Kubernetes. We use it to provision the VM's/networking for the Kubernetes cluster itself. Kubernetes might not make sense for your small scale projects but it's great when used f

I'm wondering when, if ever, the general public will start recognizing Google as one of the "big brothers". Somehow it's still perceived as this "cool" startup but they squash small businesses, avoid taxes, are

Unfortunately the range is becoming a problem on big electric trucks. The batteries cannot store as much energy per weight unit as the chemical fuel. This can be circumvented by using electric wiring overhead. Sweden is prototyping an elect

If you are relaxed and trained you can dodge the punches because it takes time for them to reach you. You really have to be aware of what is happening though, it's hard to learn not to flinch/close your eyes when the hand is flyin

Have you ever trained an SVM? Because 10000 examples is a laughably small dataset. It's not a problem for modern implementations.
