From Wikipedia, the free encyclopedia

Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).

Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

A thorough examination of the performance effects of using undefined behaviour in compiler optimizations.

Method:

  1. Modifying clang to not use UB where this is possible
  2. Run a large suite of benchmarks on different architectures, compare results for modified and unmodified clang
  3. Do statistics on the results
  4. Examine performance deviations
  5. Discuss factors which could bias results.

Very good science!

Result in short:

Only on ARM and if no link-time optimization is used, a systematic small positive performance effect can be seen. For Intel and AMD CPUs, there are no systematic improvements.

Average effects are typically below 2%, which is the typical effect of system and measurement noise. Often, effects are even negative. In some cases, benchmarks show large differences, and many of these can be fixed by simple modifications to the compiler or program.

It's kind of ironic to me that Linux is all for free and open source, but still uses a proprietary platform, and a horrible one at that. Before the fediverse, I'd understand, but now, there is no excuse whatsoever.

I understand that we can't just get up and leave everything proprietary behind all at once, since we have iPhones and Android phones. We all use proprietary software of some form, but I am of the mindset of using the least amount of proprietary possible.

I will ALWAYS look for FOSS first. I also want to make it as hard as possible for any corporation to track me. They'll probably still be able to track me, but I'm not going without a fight.

I could say the same about the Linux kernel using GitHub, but I understand how massive of an undertaking it would be to move the whole kernel to another platform. I'm sure there are other factors, too. Anyway, I just wanted to start a discussion and hear people's thoughts.
Thank you

We all have opinions on how to procedurally get someone started using Linux. To mixed effect. I wonder if we could be more successful if we paid closer attention to the machine between the seat and the keyboard. What mindsets can we instill in people that would increase the likelihood they stick with it? How would we go about instilling said mindsets?

I have my own opinions I will share later. I don't want to direct the conversation.

That's all. I can't imagine how the world and also myself would look like without them.

I'm new to #Lemmy and making myself feel at home by posting a bit!

My first Linux distribution was elementary OS in early March 2020. Since then, I’ve tried Manjaro, Arch Linux, Fedora, went back to Manjaro, and since early January 2023, I’ve landed on Debian as my home in the #Linux world.

What was your first Linux distro?

I have used Debian for the past 3 years, who else uses Debian?

Also, what makes you use Debian?

About two weeks ago, I posted my frustrations with Linux, and how it seemed unstable and breaks too easily. At the time, that had been my experience every time I tried Linux over the last 20 years.

But I made an effort to persist, tried some other distros, and found my happy place!

Thank you to the people who sent me on the path of "atomic" distros, and mentioning the likes of Bazzite, Bluefin, and Aurora (All from the Universal Blue group).

The last two weeks have been pure Linux joy on my daily-driver (Framework laptop), with only a few problem-solving expeditions.

I was looking for stability, and got it!

As a Windows user since the 90s, it's such a breath of fresh air to use an OS that's clean and designed to serve me (and not the corporation in charge!).

And I've also replaced windows on the minipc hooked up to our family room TV, and will also replace Windows that I've got on a lesser used desktop.

It's exciting to see just how far Linux has come, and even though I'll likely need to learn some terminal commands, I don't feel it's necessary for most people to even get into that.

The GUI in both KDE and Gnome already offer more than Windows. And I'll never have to see those goddamn pop-ups and banners about Office 365, OneDrive, or Xbox, at least not outside a VM!)

Freeeeeedom!

Thanks again!

Bring the Affinity Suite to Linux - #AffinityOnLinux

It's an Arctis Nova 7. It's intended to be used with a program called Steelseries GG that manages EQ profiles for the headset, as well as spatial audio, with some proprietary thing called Sonar. It also includes a mixer for managing multiple audio sources. I find the whole thing to be pretty nifty. But what I'm worried about is losing this functionality if/when I move from Windows to Linux, apparently that specific program doesn't have Linux support. Does anyone have any experience with this or something similar?

Basically the forced shift to the enshittified Windows 11 in october has me eyeing the fence a lot. But all I know about Linux is 1: it's a cantankerous beast that can smell your fear and lack of computer skills and 2: that's apparently not true any more? Making the change has slowly become a more real possibility for me, though I'm pretty much a fairly casual PC-user, I don't do much more than play games. So I wrote down some questions I had about Linux.

Will my ability to play games be significantly affected compared to Windows?

Can I mod games as freely and as easily as I do on Windows?

If a program has no Linux version, is it unusable, or are there workarounds?

Can Linux run programs that rely on frameworks like .NET or other Windows-specific libraries?

How do OS updates work in Linux? Is there a "Linux Update" program like what Windows has?

How does digital security work on Linux? Is it more vulnerable due to being open source? Is there integrated antivirus software, or will I have to source that myself?

Are GPU drivers reliable on Linux?

Can Linux (in the case of a misconfiguration or serious failure) potentially damage hardware?

And also, what distro might be best for me?

Happy Easter holidays! we made fruitful use of this time to provide you a nice surprise.

The independent, community controlled distribution OpenMandriva Lx 6.0 fixed point release (as opposed to the rolling release branch), is out right now.

i get a little annoyed at posts that start with broad statements like "is linux actually ready for the average user?" but then it's just someone asking for help to fix a problem they have with their sources.list or whatever. it's not a massive problem, but it's misleading and it feels borderline inflammatory sometimes

please tell when you're asking for help

I tried running a 2nd instance of Roblox simultaneously on macos 15 with another account but this shows up, if my mac can handle it then why can't it just let me do it? If I have two copies of an app like Roblox in separate User/Applications folders, macos moves them to the /Applications/ folder.

Sometimes it won't run apps claiming to be corrupted, so I then have to do sudo xattr -cr /Applications/someapp.app in the terminal and they run perfectly fine. It always nags me if I download apps from anywhere but mac app store. Some of these messages can only be gotten rid of by disabling system integrity protection, but then macos blocks you from running MAS apps due to having "permissive security".

I don't daily drive macOS anymore, I switched to Linux on my M1 mac where I can do whatever the hell I want.

I've been using evince to open PDFs. But for larger PDFs it is quite laggy, for selecting the text and stuff like that. Is this just a limitation of my computer, or are there faster alternatives to evince?

Hopefully this kind of post isn't too tired, but I figure it's my turn:

Finally decided to, after absolutely refusing to upgrade to 11, make the jump from Win10 to Linux! Been hopping around distros a bit and landed on EndeavourOS last night and I'm really enjoying it so far.

It's definitely tinkery and took me like 2 hours just to get my push to talk working in Discord (mostly due to my own lack of knowledge), but I love the level of control of everything you have (was on Pop!_OS before ~~🤮~~, edit: no hate, just wasn't for me!)

There's definitely never been a better time to switch and I'm very excited for when I inevitably brick my shit and come back here for help, so thanks in advance everyone! :)

Hello folks. I use many distro from Debian to Fedora to OpenSuse and Arch. I also use many window managers like i3, dwm and qtile. On desktop environment, I use XFCE the most. Currently, I am looking to try something new, hence KDE.

I am looking for something with a beautiful UI and works out of the box. So, something on the same spectrum as XFCE but more pretty.

I tried out the distros with preinstalled KDE: Fedora KDE, Manjaro KDE, Kubuntu.

The good: KDE is beautiful and very easy to use. I actually enjoy using my computer more.

The bad: it crashes.. a lot even when I turn off all the animations. My system is not that slow: AMD 7 Pro with 64 GB of RAM. Some examples:

  • Logging in, KDE hangs for 30 seconds. Even when I finally see the desktop, I would need to wait a further 10 seconds to finally able to interact, i.e. click and open stuff.

  • After resume suspend, system would hang and there is nothing I can do except for a forced reboot.

  • Browsing the web with only 3 tabs opened, KDE also hang.

As much as I hate GNOME, everything just works. I installed the GNOME flavors of above distros and never experience any hiccups.

If KDE works for you, do you use a preinstalled distro and which one? How about if you install KDE from scratch, like Arch?

Just as the title says, posting this here because I reference this all the time (maybe one day I will remember it).

I know Snaps and Ubuntu get a bit of hate in the Linux community, but hopefully this is helpful to someone. I'm not familiar with any of the reasons people don't like Snaps (I never use them unless its the only option, so my experience is limited), however for Firefox I can't use the snap package due to limitations with editing configuration files for startpages.

How did you partition your disk before installing Linux? Do you regret how you set it up?

I'm looking for some real users experiences about this and I'm trying to find the best approach for my setup.

Thank you for sharing!
