Has there been any effort of porting "memtest86+" to UEFI and DDR4?

If you don't know memtest86+ is the memory testing utility. (to find bad memory sectors) Last version came out in 2013. There is no support for UEFI or DDR4 making it incompatable with modern systems. (UEFI issue can be mitigated by switching to BIOS emulation mode but no working around DDR4)

Don't confuse with memtest86 which is proprietary. memtest86 has full UEFI support.

I am thinking about doing the port but I wanted to probe the interest. Maybe someone already worked on porting?

Do you also think that currently desktop Linux experience is discouraging?

I'm Linux user for more than 20 years, but some time ago I'm thinking more often to leave it and only use it for command-line purposes. UI Performance is sluggish on every distro, every environment, every hardware (AMD, Intel, Nvidia, it doesn't matter, on every driver).

Worst of all is that ALL browsers work slower than on Windows (I mean time between link click and full page load) and it's my primary tool. Why nobody is talking about that? You can force enable hardware acceleration and it still is bad. Finally, the fastest browser on Linux is made by Microsoft. Never thought that it could happen.

Gaming, despite the involvement and great work of Valve, still is like kicking a horse. Trying to run things like PlayOnLinux finally ended messed up dependencies in apt.

My favorite years with Linux were about 2010-2015 when very much of everything worked. So what went wrong?

I don't want to sound like bullying Linux. I Love the os, and I mark everywhere the importance of open source, but the current desktop experience is discouraging. Now, I'm trying to work on something that I named "Frankenstein OS". So I'm using Windows 10 as my "desktop environment", bash, and beneath all features of virtualized Linux bound to second physical disk with shared profile directory, etc.

What are your thoughts?


EDIT: Problems list much longer than mine only:

Linux Is Just More Efficient

So over the past couple of days, I've been reminded yet again of my primary motivation for switching to Linux 10 years ago and why most of the people I've switched over have continued to use it without much complaint.

For the record, I don't consider myself much of a Linux evangelist. I fall more in the camp of "if it works for you, just use it". That being said, my socioeconomic background lends itself to myself and people around me having laptops that are just basic work tools and not overly powerful. My primary device for instance is a used Thinkpad T430 with the base level I5 dual-core processor which I use as a desktop replacement in a dual monitor setup with the aid of an old docking station (very handy for such an old device).

Against that backdrop, I recently accepted some additional data entry work mostly done via Teamviewer into a dedicated work Desktop. Now to the point of this post and why I just can't go back to Windows for a primary OS. The desktop PC in question is a 2019 machine with 8GB RAM and a 6 Core i5-9500 processor (2019 model). Just for a basic workflow of a few word documents, a couple of excel worksheets, one database program, outlook, teams and some PDFs, the desktop was constantly pegged at around 90% RAM usage and upwards of 40-60% CPU usage. All this while the host machine I used to Teamviewer in (the aforementioned T430) runs a relatively bloated setup of Plasma 5.21 with multiple chat apps going, irc client, c few spreadsheets of my own, news feed reader in the background, email app, file sync app and of course a browser with multiple tabs including at least 2 youtube tabs at any given time and RAM usage with all this tops out at a cool 4.2 GB (4.3GB if I pause to play some GBA games occasionally) and CPU usage hovers around 3 - 16% and occasionally jumps up to 40-60% if I'm streaming vids at 1080p60 while doing light gaming WHILE the teamviewer instance is running.

​

I know this is a lengthy one but occasionally, I just like to take note of these things and remember why I switched in the first place. Windows 10 with basic usage has the potential to bring a 2019 6-core Desktop to it's knees in under 7 hours of uptime with a standard workflow while linux allows for a significantly heavier workflow on a now 9 year old laptop acting like a desktop and punching far above it's weight class despite a current uptime of 2 and a half days (because I rebooted after making some modifications to new plasma install). Linux rocks!!!

4K videos lagging on Linux

I am currently running Ubuntu 20.04.2 on a non 4k screen and average hardware. A few months back I had Windows 10 and tried to play a 4k video in it. As expected, it was playing choppy.

I updated the outdated VLC and tried again. This time the video was playing smoothly. I also installed MPC, and the 4k videos were playing just fine it that too.

Fast forward to the present day. I tried the same thing with VLC. It plays all choppy with full of gray glitching screen. Tried all the online solutions to fix this, none of them worked. I downloaded a different 4k video, but same result. I tried playing these videos on my phone (which supports 4k) and they play fine.

Now don't give me "It's because your hardware doesn't support it" because I have played 4k movies on this same desktop months ago when I had Windows and there were no problem. I'm facing this only on Linux this time.

Running Python Script when i open a application

Im using an eink display on my Raspberry pi and am wanting to display custom screens when certain applications are opened (Nethack, Ranger, Vim, etc.) I change the display via a Python program, and am wanting to be able to run the program when I open the applications. Is there a way to make the python program run when I enter the command to start the app (Ex. $nethack) or can I see a list of the running applications and see if it is active from there.

I am running Raspberry Pi OS on a Pi0 and am connecting to it via SSH so only one terminal is open at a time.

What’s your favourite Linux OS?

Hey everyone,

I’m taking a Linux/Unix based course in college and am wondering what some of your opinions are on what is the best version of Linux to run?

I’m planning on installing Linux on my system for my next semester and am curious as to what you all prefer?

I didn't know this incredible shortcut! Did you? Linux is awesome!

Did you know that you can copy a file and paste it in a "File Open" dialog?

It magically write the path to the file in the location bar!

You juste press CTRL-V, that's it! no need to click or select the location bar!

At least it work on my distro which is Linux Mint Cinnamon.

Does it work in all distros? Does it work in your distro?

Linux's Political Implications and Future Outlook

This might be a bit in the weeds, but I'm a relative newcomer to Linux and I can't stop thinking about its socio-political implications.

It seems like Linux and FOSS generally have serious political weight, and not just in the sense of making it possible to, for example, circumvent censorship or communicate anonymously (or close to anonymously). What I'm thinking of is more that right now, there is free software which in many cases is as good or better than its proprietary counterpart, and which is being developed in large part as an unpaid hobby.

Is anyone aware of any scholars that study this sort of thing? I did some cursory googling and it doesn't seem like there are a ton of people writing seriously about this angle.
