Does anybody know of a list of usb live-bootable distros, with links to the download pages?

I have a coworker who wants to switch his gaming computer over to Linux, he has Linux experience but from like a decade ago.

He's not partial to any particular distro, so I was hoping to just put together a multiboot flash drive with a bunch of live images he could try. But I'm not sure what I should include, and what has live images, vs. install only images.

I'm most comfortable in an environment with apt, so Debian and Mint are of course already covered, but if the gaming-specific distros have live usb images, that would probably be the best thing for him to try.

For most of college, I’ve kept it simple: I’d create a directory in my home folder for each project, then eventually move older or inactive ones into ~/programming/. When I change devices or hit file size limits, I’ll compress and send things to my NAS.

This setup has worked pretty well so far. But now that I’m graduating and my projects keep stacking up, I’m starting to wonder if there’s a more efficient system out there.

Curious—how do you all organize and store your projects? Any tips or methodologies that have made your lives easier over time?

The only person I’ve talked to about this is my mentor who’s been programming since the 60s (started on the IBM 1620 and Bendix G15) and he just mostly keeps projects in directories in his home directory and uses his godly regular expressions skills to find things that way. Makes me wonder if I’m overthinking it…

Hi guys.

Just started looking at using Linux on my main pc. I don't use it too often these days but I like to play around with my pc.

I tried Fedora and it seems fine. I chose Fedora 41 as I wanted to have working Nvidia drivers and secure boot. Got that working but then I tried to use my wireless Xbox series X controller and had no luck getting it working. I tried to install xone but was getting errors.

I've tried Ubuntu is the past but just wasn't to my liking. Linux mint was ok but didn't like the available desktop environments.

I know Nobara is available, but I'd prefer to have something minimal and be able to configure everything myself to my liking.

I'm not so fussed about which distro. Can anyone recommend something that works with: Nvidia drivers Secure boot xone (or something else)

I like the gnome desktop environment.

Thanks. ☮️❤️

I had a teeny pet project using GNU assembly that was going to target two platforms.

Instead of keeping my handwritten worst-practices Makefile I decided to try GNU Autotools for the educated reasons of:

• Text scrolling by looks pretty
• Vague memories of ./configure make make install tarballs

I got hit with mysterious macro errors, recompile with -fPIE errors (didn't need this before?), autotools trying to run gcc on a .o file w/ the same options as an .s file, "no rule for all:", and other things a noob would run into. (I don't need a bugfix, since my handspun Makefile is "working on my machine" with uname -m.) So there's a bit of a learning curve here, inhibited by old documentation ~and~ ~more~ ~quietly,~ ~genAI~ ~being~ ~shittier~ ~than~ ~normal~ ~in~ ~this~ ~department~

With this I ask:

Do people still use Autotools for non-legacy stuff? If not, what do people choose for a new project's build system and why?

edit: trimmed an aside

I updated my graphics drivers from nvidia 470 to nvidia 560 due to issues running certain games. It's fixed my gaming issue but reintroduced the problem that kept me from updating for so long.

After setting my computer to "suspend," it wakes up to this screen on all monitors. I am unable to scroll up or type further commands, my only option is to reboot the machine.

• My graphics card is: NVIDIA Corporation GP104 [GeForce GTX 1070]
• Nvidia driver version: 560.35.03
• My desktop environment is Cinnamon X11. (This does not occur on Wayland, but there is no Cinnamon Wayland.)

I can't make heads or tails of this error screen. The best I can understand is the "Fixing recursive fault but reboot is required!" line. How can I get more information? Does anyone have any ideas on how I can fix this? Thanks in advance.

Edit: It seems important to mention this is happening only on X11 (Pop default and Cinnamon), and not on Pop!_OS on Wayland.

(for anyone who do not know, bc is a "arbitrary-precision arithmetic language". its syntax is similar to C)

Gavin Howard's bc (bc-gh) is adopted by busybox, toybox, FreeBSD, Android, macOS for its robustness and superior performance. It is also shipped with Gentoo Linux; LFS also use bc-gh.

Even though bc-gh is more robust and updated, Linux distros other than Gentoo and Fedora do not package it it. bc-gh is not available on Arch (available on AUR), Debian and perhaps all of its derivative. The reason seems to be a licensing reason: bc-gh is under the BSD license.

bc-gh is clearly superior to GNU bc, Gavin Howard's benchmark show that bc-gh is faster than GNU bc in most case, while bc-gh actually do more work than GNU bc.

Today I tested GNU bc and bc-gh. I let they do this operation: (1024*1024)^(1024*1024). GNU bc give me the answer in five minutes, bc-gh give me the answer in two minutes.

GNU bc do not have a repository. All development happen in private, and we can't make sure it is still maintained. The latest version is 1.07 from 2017. bc-gh have a public repository and it is actively maintained.

So it is clear that other Linux distro not adopting bc-gh is purely licensing reason. They reject software not under the GPL license, even if they are more robust and more performant.

We need a campaign to raise awareness about superior software alternatives. We need to stop Linux distro for not adopting superior and updated softwares for licensing reasons.

Hi there, was thinking around of the best place to post this. Initially I thought maybe the Dovecot mailing list but I'm not sure if this is a Dovecot issue or if the issue lies with Postfix, so I figured maybe a more general Linux community. If people have suggestions about where I could post this that may have more people see it who are able/willing to help, I would also appreciate that.

I apologise, this post will probably be quite long, so I really do appreciate if anyone takes the time to read it and give advice.

Anyway, I was following this tutorial to set up a mail server with Postfix and Dovecot. The tutorial is for Ubuntu but I am using an Alpine Linux server, however the tutorial mostly concerns configuring Postfix and Dovecot which is distro-independent.

Deviations from the tutorial

I followed the tutorial with the exceptions of the following (deviations listed in order of the part of the tutorial they deviated from, so hopefully this is easy to follow linearly):

My server's hostname is domain.com not mail.domain.com (mail.domain.com is what my MX record points to), but this shouldn't really matter as I configured postfix with:

myhostname=mail.domain.com
mydomain=domain.com

I installed packages with apk not apt obviously, and installed Postfix with doas apk add postfix.

I didn't get the ncurses Postfix configuration popup when I installed or started Postfix.

Alpine doesn't auto-start the Postfix service, so I did

doas rc-update add postfix default
doas rc-service postfix start

I used doas apk add mailutils --update-cache --repository https://dl-cdn.alpinelinux.org/alpine/edge/testing/ to install and test the mail program.

I didn't increase attachment size limit.

Alpine doesn't seem to have a dovecot-imapd package, so I just installed dovecot and dovecot-lmtpd.

When configuring /etc/dovecot/conf.d/15-mailboxes.conf, I also set Drafts, Junk, and Sent Messages to auto-create as well as Trash.

I started the dovecot service the same way I did postfix above.

What works

I can send mail with sendmail and GNU mailutils mail. The following works:

echo "test email" | sendmail my@email.com

And

mail -a FROM:me@domain.com my@email.com

(where domain.com is my Postfix mail server, and my@email.com is my existing email address with an external provider)

The above results in me receiving the email in my spam folder at my@email.com from me@domain.com, email all appears normal to me.

The issue

I've noticed two problems which may be related.

Can't log into Thunderbird

Firstly, I can't log into Thunderbird. I get the following error:

(Transcription: Unable to log in at server. Probably wrong configuration, username or password.)

To log in, I am entering my email address at user@domain.com, where user is my UNIX user (which is part of the mail group), and domain.com is my domain. I entered my password as my user account's password.

Thunderbird seems to recognise my mail server as it auto configured to the following:

INCOMING: IMAP, hostname mail.domain.com, port 993, SSL/TLS, normal password, username user (i.e. without the @domain.com)

OUTGOING: hostname mail.domain.com, port 465, SSL/TLS, normal password, username user

I have also tried the same configuration with STARTTLS and ports 143 and 587, to the same error.

Can't receive mail

I've also tried to send myself emails from my other email addresses. I've tried two of my external email addresses so far. My email clients say they've sent the emails and they appear in my Sent folder, however my Protonmail has sent me some emails today from their mailer daemon complaining that Your email could not be delivered for more than 12 hour(s).:

<user@domain.com>: host domain.com[MY IP] said: 454 4.7.1
    <user@domain.com>: Relay access denied (in reply to RCPT TO command)

I've checked /var/log/messages (which is the Alpine Linux syslog) and found the following, which I don't know how to interpret:

Nov  2 17:57:03 domain mail.info postfix/smtpd[28188]: connect from mail-41103.protonmail.ch[185.70.41.103]

I have dovecot configured to use the maildir format (or at least I think I do; I followed the tutorial to set it up to use maildir) but I don't see anything in my ~/Maildir directory.

Running GNU mail results in the output:

Cannot open mailbox /var/mail/user: No such file or directory
No mail for user

Hello,

I bought a razer blade 15 laptop a while ago, and world like to install Linux on it, mostly to play games. So, ideally I'd like a distro that can make the most use of the hardware and let me play the most games, while being the easiest to use and lowest maintenance possible. Any recommendation?

I've attached a literal screen shot of all systemd errors. It seems to be caused by kscreenlocker_greet because of a missing shared object file. The boot 9 hours ago was from a read-only snapshot, and therefore doesn't have it.

I have already tried updating with zypper dup, but that did not help.

Error as text:

PAM unable to dlopen(/usr/lib64/security/pam_pkcs11.so): /usr/lib64/security/pam_pkcs11.so: cannot open shared object file: No such file or directory

This is an Acer Aspire one laptop, with a 32 bit CPU and Debian 12.7. Whenever I install Linux on it, the Internet works for about one day. And when I boot it up the next day, it just stops working. This is the case for WiFi, Ethernet and USB tethering via Android.

After running networkctl it gave me this:

I can ping 8.8.8.8 in this state, but not gnu.org. I can't open websites in Firefox either.

Then I ran "sudo systemctl start systemd-networkd". The networkctl output changed but everything worked exactly as the above two images. Couldn't open websites still.

Yesterday everything was working perfectly

Edit: Thanks to @nanook@friendica.eskimo.com and @MyNameIsRichard@lemmy.ml I finally have internet access on my 12-year old e-waste!

We're kicking off our 2024 end-of-year fundraiser just in time for Halloween!

Even if the spine-tingling horrors of the long dark night of Walpurgis are mostly imaginary, the sinister threats of predatory proprietary software providers remain all too real.

Fear not! We, the KDE community, will help you, your friends, family, company, and community banish all the creepy and insidious proprietary software that haunts your computers, phones, and household appliances.

But we can't do it alone! We need you to help us fight the good fight against the tech-ghouls from beyond. Use the form to donate any amount to our fundraiser (or become a regular donor to our community) and help us keep the dark forces of proprietary software at bay.

I downloaded the AppImage file from the GitHub Repo and I did check that my USB Drive is connected which I can access it through my File Manager as well as Gnome's Disk Utility.

Oddly, when I tried to set an directory for Movies and TV-Shows in MediaElch, it acts like I hadn't plug my USB drive.
