Rebuilding a "software development stack"

I'm the admin on for a small workstation/cluster used by my research group which manages it's software using Environment modules. I've just finished compiling a sequence of dependant software (e.g. gcc 9 -> cuda -> open-mpi -> FFTW) and am about to start the process again using a different starting compiler (e.g. intel compilers -> cuda -> ...).

I'm writing a BASH noscript to automate this process, but it's lead me to wonder how this scenario is typically handled?

I'm working in computational physics and have done a decent amount of software development for simulation packages in my particular niche. But I've no formal software development training. It be great if some could give/point me towards a high level overview so I could incorporate some relevant terms into my "Google-fu".

EDIT: To clarify, I'm wondering if it's typical to use BASH noscripts, make, or some other tool all together? Is there even a standard practice?

Are there any Red Hat System Administration I (RH124) certified folks here?

Hi everyone,

I was wondering if anyone has any recommendations for some solid study material for the Red Hat System Administration I (RH124)?

I have VERY little knowledge Linux and I am just looking to expand my career in IT with Linux.

Any help is greatly appreciated.

Why is systemd disliked?

Note: I know there was already a post about this. It’s a few years old, so I wanted to ask again and see if anyone’s opinions changed.

A lot of people don’t like systemd, saying it does too much stuff, does more than it should, and saying it goes against the UNIX philosophy. I don’t really find the last point valid since Linux isn’t UNIX, but I mean whatever you want to believe I guess.

Cannot Boot Linux after Optee

Hi,

I'm working on the ZC702 board and trying to boot Linux and Optee. My boot flow is:

FSBL--->U-Boot--->OP-TEE--->Linux

Although Optee is booted successfully, Linux hangs on the 'zynq_early_slcr_init' function at booting.

Probably Op-tee OS locking down access the SLCR. So When Linux accesses SLCR, the system crashes.

How can I solve this problem?

Enforcement of AGPL

Lets say i write an AGPL program. If someone uses it in their website they have to also license their code AGPL, but unless its an obvious big modification, how do i know the code they released is the one they are actually using in the website ?

GNOME Extensions Rebooted: Porting your existing shell extensions to GNOME 40

This isn't on Planet GNOME yet, so I'm putting this out there as a PSA. If you could pass this along to your favorite extension author that would be great! GNOME 40 is almost upon on us and the extensions rebooted initiative continues apace. Here is the latest update - and hopefully we can get more extensions ported before GNOME 40 lands on distros.

Linux certifications

I'm pursuing a career in IT and want to get a Linux certification(s) which one(s) should I consider. Currently I'm taking a Cisco course on Linux that offers a coupon for the LPI exam after completion. Is this a good start?

About the Linux Community ;)

I am using Linux for about 1 year, but the specific part of the community which disturbs people if they don't think what they think is something I really hate. (Large amount of this guys are in the "toxic" part of the Arch community).
I love the Linux community which is polite and here to help people or improve Linux to make it better. That is why I really switched. It has changed me to think more positively, wanted to give help to others etc.

You are free to use/do what you want in Linux. This is what I really love.
But you are free as much as you don't interrupt others freedom. This is what I think the freedom means. What do you think about this, I want to listen :)

IMHO,
You can't say "dumb" to somebody that uses something like Linux mint or because s/he doesn't use what you use. You are not better than the other person because you use arch etc. (this is just and example for general case.) For example, you can hate ubuntu. But distracting the people who use Ubuntu doesn't make you a better better person. Even the opposite. And you can't deny that ubuntu helped Linux more than YOU while you're just hanging around with your impulsive speech (in general cases). I don't defend Ubuntu here, this is just most common situation to give as an example.
And what about non-technical users or newcomers to Linux? I hate when they're underestimated by the toxics. Are you happy when you make other people hate? :/

I just want to see more happy penguins in community, is it a lot ;)?

Installed KDE Neoen and it says Pop OS

So i installed kde neon from the official site 3 days back and today checked neofetch and it said Pop OS. I thought it was a problem with neofetch and tried with pfetch only to get the same result. and then i tried the command "$ cat /etc/os-release" in the terminal and got the same result. I used both the bash konsole the os came with and alacritty. And the weird thing is while booting the splash screen and the dual boot menu says KDE Neon. Is there a possible explanation for this?


Edit: ignore the Neon typo in the noscript.

Gnome performance one step forwards, one step backwards...

This post will not be popular with gnome fanboys. These last few years, things were looking up in terms of performance, a lot of Daniel Van Vugt (and others) patches yielded big improvements. With Gnome 40 RC, there is a noticeable regression from 38, animations randomly lag at times and then speed back up. The UI design is great but it comes with a big cost. Using GNOME 40 RC feels randomly sluggish at times and the user experience suffers greatly.

Gnome fanboys will hurry to say " you must have driver problems" or other things they have said in the past. NONSENSE.

​

I love gnome and my goal is not to trash the project, but why not delay gnome 40 and work on its performance before releasing it ? Releasing it in march will probably result in a lot of people being disappointed in the project...
