Yeah, it’s possible to change case while loading, but I’m not sure that’s gonna be much faster. But I’m sure it gonna be much harder. For non-ASCII strings, converting case may change their length in bytes. You don’t even know in advance ho

> how fast the CI hash and equality operate compared to the CS ones. If the string is ASCII like in the OP’s use case, I think the difference is not huge. CS comparison looks more optimized, they have an inner loop which compares 12 byte

The C# standard library will not run many case-insensitive comparisons. That comparison object doesn’t just compare two objects for equality, it also has another interface method which computes a hash of a single object. Here’s implementa

In 2000, the performance overhead was too large. PowerShell, and most of PS applets are written in C#. PowerShell is a lightweight scripting layer on top of the same .NET runtime. BTW, last couple times I dealt with Linux, I remember essent

The definition of DSL is vague, but at least in some sense, some operating systems do implement such a DSL. For Windows between 2000 and 7, that would be VBScript. The language itself is primitive, but through various COM APIs (WMI, ADSI, A

It's an awesome installer, I used it in the past. If a person knows any scripting language at all, I think they will create an installer with NSIS in less than a day of work. Still, for commercial-quality software I prefer my installer

I like the new <bit> header. In C++/20 they added support for BSR and BSF instructions from 1985, introduced in Intel i386. In C++/23 they even added BSWAP instruction, much newer one, introduced in 1989, in Intel i486. Most

Some programs need gigabytes of memory, and all CPU cores, for legitimate reasons. I believe the actual problem here is the UX. Modern operating systems aren’t doing a great job communicating per-app resource consumption to end users. I thi

They do similar job in the sense they both generate data for hardware rasterizer, but I think the differences are rather large. That PS2 coprocessor is similar to a single ARMv7 core with NEON. Mesh shaders don't run loops for elements

Mpeg-4 can do that just fine. Here’s what MediaInfo tool shows about the video stream of some *.mp4 file on my computer. The content was first released in 1997, before modern digital stuff. Frame rate mode: Constant Frame rate: 23.976

Many multimedia formats, frameworks and libraries actually store them that way. In Mpeg 4, each track header has a “time scale” integer field. For a video track of 23.976 FPS the value can be 23976, or half of that, 11988. Audio tracks typi
