It looks to you . IMO secure software comes from knowledge and care as much as from a safer language, if not more. But then there is performance, in which what no "modern" "safe" language even comes close to C. >Mean

Does anybody have an example of good performance of unaligned memory access on modern cpus ? And note that it doesn't matter if the cpu supports AVX, but if it has a flag that says it can do fast unaligned memory access (i don't r

Don't do unaligned memory access, whatever your cpu flags say. Another thing you can do, if you don't plan on using the results immediately, is to use non-temporal store (movntps for SSE2). If you do plan to use the results right

I was interested in how key events are generated and how the driver in the computer was made (if not the generic driver). But that was handled by a premade mini computer and OSS software.

Inspired by "Pitfalls of Object Oriented Programming"[0], i did something similar to this (in C). Idk how the cpu usage would be by doing it another way, but this way processing thousands of matrices is no problem. [0] http:&#x2F

The transistor was invented in 1925 by Julius Edgar Lilienfeld (a FET). The first one built was in 1947 (a BJT). A metal-oxide (MOS) transistor is a FET. Commonly known as MOSFET.

Something like "(x 3+(y/20) 5)" will generate a few lines of assembly (about 3 to 5 in this case, assuming registers are pre-loaded). But usually no, there won't be much more code. For example "while(1){..." eq

People rarely differentiate "complicated" and "complex". I get the feeling from GO that it was designed for making complex programs.
