How can I record and cut a sound in c++
http://libsound.io is a great cross platform library for reading and writing to sound cards. i have used it successfully on macos and iām sure it supports linux and possibly windows too. you will probably also need lib audio for reading and writing to files.

Learn Enough C to Survive
Hmm... after some research it seems that I've misunderstood Zig's situation a bit. Zig has introduced null-terminated string types a couple of years ago, but still encourages you to do most string operations with slices instead. Let me explain:
Zig's string literals (which you create with parenthesis like "Hello world!") are null-terminated byte arrays, expressed as the type const [N:0]u8 (where the :0 tells you that it's null-terminated), whereas the more typical array might be written as const [N]u8. The reason for this feature is not because the language wants you to use null-terminated strings, but because these static strings need to be stored in the global data section of the ELF executable, and these require you to use null-termination. But if you want to do any mutable operation with this string, you need to convert this into a proper slice (ptr + size). And it seems like Zig developers don't really use null-terminated types that much at the API level, but use it for things like C interop or cases where you really need it for special optimizations.
Noting that from the PR that introduced this feature, Andrew Kelley writes:
> I think you will find that the Zig community in general (and especially myself) agrees with you on this [null-terminated strings being fragile], and APIs in general should prefer slices to null terminated pointers. Even if you are using Zig to create a C library, and even in actual C libraries, I would recommend pointer and length arguments rather than null terminated pointers, like this: https://github.com/andrewrk/libsoundio/blob/1.1.0/soundio/so...
> That being said, I want to repeat what I said earlier about null terminated pointers: A null terminated array is not inherently an evil C concept that is intruding in the Zig language. It's a general data storage technique that is valid for some memory constrained use cases. I also stumbled on a Real Actual Use Case inside LLVM. The bottom line for me is that null terminated pointers exist in the real world, and especially in systems programming. You can see this in interfaces with the operating system in the standard library...
So he acknowledges null-terminated strings can certainly be useful in certain situations outside of legacy reasons, which is good to know. And Zig creating a special type for this shows that a good systems language needs to be designed to accommodate the needs of the outside world.

Ask HN: Cross platform method for accessing system audio output?
Perhaps you could use either http://libsound.io/ or SDL2 game library + SDLAudioIn (http://burningsmell.org/sdl_audioin/) which provides low-level APIs to access operating-system sound systems like Alsa, PulseAudio, PipeWire, and CoreAudio (not sure how well it is supported by SDL2).

Is programming truly for me?
Fun fact: Andrew Kelley, the creator of the Zig programming language, kind of created it so he could work on audio processing.

Jam live with your friends with Svelte!
I listened to the Co-recursive podcast the other day that featured Andrew Kelley, the creator of the Zig programming language. Before Zig he developed Libsoundio - https://github.com/andrewrk/Libsoundio, to solve problems around realtime audio.

Mach Engine: The future of graphics (with Zig)
Audio will probably come later, but libsoundio will be the first thing in terms of groundwork. Integrating that in the same way we've integrated GLFW, so you can just cross compile and get cross-platform audio to boot.

Manually Playing PCM Audio
Sound data is double-buffered by the operating system. The OS gives you one buffer to write into while it plays the other, and then they swap. If you want to write real-time audio (i.e. a program that will actually play sound itself with no libraries), you need to either read up on your operating system's kernel API for audio, or use a thin abstraction layer like libsoundio. You could also use a fully fledged library like IrrKlang that just does everything for you.

Redis License Changed
I'm curious about something: I suppose Salvatore still owns the copyright for most of the code? The old license does include his copyright, up to 2020: https://github.com/redis/redis/blob/7.2/COPYING So I think this change couldn't have been done without his explicit consent? Or did he transferred his rights to RedisLabs or a foundation?
Redis.io no longer mentions open source.
They have still not changed meta description on their page. It still says it is open source ^^

Redis Adopts Dual Source-Available Licensing
First they break lolwut (https://github.com/redis/redis/issues/12074) and now this.
Redis Inc. is moving the https://github.com/redis/redis/ project away from the three part BSD license to a dual license using two non-OSI approved license. This comes after previous comment from them saying that "... the Redis core license, which is and will always be licensed under the 3-Clause- BSD".
> They get paid for it. Don't try to spin this as if it's someone people working on it in their spare time out of the goodness of their heart. It's just their job.
No, you can't have this both ways. I'm the main contributor from AWS, and I've worked many times on weekends because I care about open source. I like helping people, I don't need to be paid to do it. Many of the AWS folks that made changes were normal engineers that were excited to be part of Redis. https://github.com/redis/redis/pull/10419 and https://github.com/redis/redis/pull/8621 are both examples of features someone from AWS built in their free time. We're all upset about this. Not because Redis deserves to get paid, it's that they acted like they were being good stewards of the open-source community and then they changed their mind.
