This brings back memory of one of my projects. After I had couple years of professional development under my bell, I started contract work on the side. I've done a project with a client and it was a success. They wanted me to tackle

This is a fantastic news. I got into Zig in the last two weeks and it has be a very pleasant language. The comptime is an ingenious invention. It enables type safe meta-programming and easy generic support, in the same language syntax.

Silicon is the perfect material for semiconductor. It has a low band gap energy between the valence band and conduction band. A small amount of energy, electricity applied to it, can knock its outermost valence electrons off and it becomes

Same here. I thought they sent that email out to incentivize me not to move to fiber. Turns out that FCC is the reason.

Just this week I start looking into Zig. It's a joy to use the language. The compiler and the build tool come in one executable. Most of the needs to decide on the project structure are eliminated. The project scaffold including th

Machines used to have limited memory. Distributed caching can utilize many machines to form the overall cache. Nowadays machines have plenty of memory with numerous cores and fast bandwidth. The need for large network of cache servers has

Depending on how you do rendering, vanilla JS can be extremely fast. For most web apps, the initial layout and rendering take the biggest portion of the rendering budget. Subsequent changes are minimal and can be rendered very fast. If yo

CPU’s not running the main thread don’t care about the execution order of the instructions of the main thread. They only see their local caches of the same memory location got changed from 0 to 5, 5 to 0, and back to 5 repeatedly. When a ne

He just read OP's code, the C++/STL Standard, and the Microsoft Learn document and made that conclusion. That's a rather haste determination. Unless he read the actual Windows lock implementation and found a bug there, I do

The main thread is running the child thread creation in an endless loop, repeatedly setting numThreads to 0 and to 5, back to 0 and to 5 again. Can the caches of the CPU's consistently keep up with the changes?

The program has a bug. It's mixing atomic and non-atomic variables in the yield() checking loop. Non-atomic variables have no guarantee on cache consistency for different threads. This can cause the loop to run forever. struct

Lock free has two advantages: the checking code can run in user mode and non-contested access is very cheap with just one instruction. To do it correctly, lock needs to be done in the kernel thus obtaining a lock requires calling into the k

The second term is not a cross product. It's the exterior product (or bivector). Cross product only works in 3D. Exterior product can work in any higher dimension. A cross product of two 3D vectors is another vector, perpendicular to t

I have done a fair amount of Rust. The complexity is not in the borrow checker or lifetime. It’s in the combination explosion of the of generic, traits, lifetime, and constraints. When a struct takes on these, all functions and impls need

RocksDB supports point query and range query. This only supports point query. Also I'm not sure whether FASTER supports transaction, as the paper didn't mention it.

Re2c only performs the tokenizing part, not the parsing part. Re2c should be able to run a regex to recognize N spaces and produces a n-space token. It will be up to the parser to use that to get the indentation of a statement.
