The last recording didn’t make it on YouTube as I was using unlicensed music on the stream.
Tomorrow we will be testing out the NixCon streaming infrastructure. Join in to help! I will be sending out the details on Twitch and redirecting the public from there.
This Nix Friday I will be in the stream as well and we will talk about the C/C++ infrastructure in nixpkgs. We won’t talk too much about the language itself, but how the compilers/linkers are integrated into stdenv and how the build system abstraction works. If you happen to package C/C++ applications or libraries, this should give you a good overview. If you have any question you want to answered, please post them here: Nix Friday: C/C++ questions for next stream
Here is the recording for our latest session. If you ever wondered about the nitty-gritty details on how C/C++ programs get built, @Mic92 has done a thorough and intense job of building the knowledge up. The first part is directly C, and then later on integrated to Nix.
Is there any chance you have a recording with each microphone on a separate audio track? Or at least one where the two input channels are mixed at similar volume levels?
It’s hard to tell for sure, but it seems like the even the pre-amp noise (or ADC noise?) from one side is mixed to be at a higher volume than the voice from the other. (I’m assuming that’s not intentional.)
I have purchased a new microphone, hopefully, this will improve the audio quality. Both audio tracks are on different channels in OBS, unfortunately, they get merged in the stream so it’s difficult to apply post-processing to it.
It looks like OBS can record up to 4 audio tracks, one of which it will stream live. If you can tolerate the additional CPU load (and disk space) it might be worth trying.
I’m not sure how much a new mic would help. If it reduces the static that might help a bit, but I think the main problem is Mic92’s voice got mixed at a very low volume. Was it coming through all right for you during the call? If so, perhaps it’s just a matter of adjusting the OBS Audio Mixer so the two channels end up at a similar level.
Indeed. I keep forgetting to tune the audio before starting the stream. If you keep watching, a listener eventually tells us to fix the audio and I adjusted the levels.
I would be more than happy to get some help and have them duplicated on PeerTube. The issue is just the amount of extra work that it would take on my side.
Could you please do a video about cross compiling?
I have a very old and slow machine (i686). Everytime I run sudo nixos-rebuild switch, it takes a very long long time to build some packages. I’m thinking about having NixOS running cross compiling on another powerful machine, then download build artifact and install on my slow machine
I’ve found some articles about this but I couldn’t execute this. It’d be great if you can do a video showing step-by-step on how to do it
