There's a command line compiler option to avoid reliance on VC++ redist: /MT (in release mode) or /MTd (in debug mode). Default is /MD (in release mode) or /MDd (in debug mode). With /MT or /MTd Microsoft

It can be some system bound to domain names of software developers/vendors (like Let's Encrypt, but for code signing instead of TLS).

It's no big deal as long as JIT compiled code is restricted to the safe subset of instructions. For example, in FreeBSD BPFs (berkeley packet filters) are JIT compiled and directly executed in the kernel mode.

According to [1], on recent Intel CPUs, each instruction is translated by hardware decoder to up to four micro-ops: either trivial micro-ops like addition, subtraction, bitwise and/or/xor, or a special "microcode assist"

Usually there's no need to convert NFA to DFA. NFA can be simulated directly, i.e. by using bit vector instead of integer for state accounting. Also, no backtracking is necessary to simulate an NFA.

I use Far Manager (with plugins, e.g. Colorer and NetBox) on Windows (in ConEmu). Total Commander and other GUI based filemanagers are too far disconnected from command line, in my opinion.

If dedup is off, and max ARC size is limited, it will use a little memory (e.g. 512 Mb of RAM for 2x2TB RAID1 pool). I can say that from my own experience, I tried both approaches.

It's also worth noting that FreeBSD used to rely on M:N threading model (via libkse) then switched to 1:1 threading model (via libthr).

I run FreeBSD with ZFS on the home server, which primary purpose is storing and processing video files from two surveillance cameras. ZFS pool is created as RAID-1 array of two 2TB HDDs. Server has 2GB DDR2 RAM, but ZFS in-memory cache is r

Ah, now I see these things changed recently. I wrote original comment because at the time of Go 1.1 or 1.2 my colleague wrote racy code which accessed global variable without mutexes. I tried to educate him to use mutexes, by reducing his c

Go runtime library contains user-space scheduler which maps lightweight Go threads to heavyweight OS threads in M:N manner. By the way, Go runtime library allows running user code in only one OS thread per process, all other OS threads must

You have a very good point about disabling updates. Everyone here seems to think that OS updates are vital-important, but they are not. If you are running latest browser, instant messenger and personal firewall, you are unlikely to catch ma

You are talking about high advancements in the compiler research. But is there any statistically significant performance difference between the code compiled via latest GCC vs. OpenWatcom (which is unmaintained for a few decades)?

Well, using the terminal instead of explorer in Windows because people don't like the mouse is quite extreme, but using the Far Manager for the same reason is more common, at least in my environment.

You can use _alloca(), however be careful not to overflow thread stack. This applies to C99 variable length arrays as well.

Adding Javascript support to high-performance reliable web server does not seem rational from the engineering point of view. I'd rather added support for the safe subset of some statically-typed, high performance language compiled to L

There's no curl in default Windows installation, but "bitsadmin.exe /transfer" can do pretty much the same, and the shell (cmd.exe) has been around since Windows 95. So, actually, yes, but unfortunately without a pipe.

Also code produced by LLVM-based languages can be linked with low-level modules written in pure C/C++, or even assembly, if necessary. So one may quickly prototype and then slowly rewrite the software for performance, module by module.

Copy-on-write fork is not compatible with Win32 global (interprocess) mutexes. After fork succeeds in context of process with acquired global mutex, should parent or child automatically release that mutex? Copy-on-write fork existed in POSI

BOUND instruction on x86 architecture exists for time immemorial, but not widely used and may be slow in modern microcode (like AAM/AAD and other stuff of handwritten assembly era, never emitted by compilers).
