So they actually rewrote The Hurd in Rust.

Is Ubuntu deserving the hate? (lemmy.ml)

Long story short, I have a desktop with Fedora, lovely, fast, sleek and surprisingly reliable for a near rolling distro (it failed me only once back around Fedora 34 or something where it nuked Grub). Tried to install on a 2012 i7 MacBook Air… what a slog!!! Surprisingly Ubuntu runs very smooth on it. I have been bothering all...

cmeerw ,

I still think Ubuntu is the best option (particularly if you want to use the non-LTS releases)

Having said that I do hate snaps and also dislike flatpaks. So what I do is just use the Firefox deb package from the PPA and the chromium package from Linux Mint. Oh, and I have actually replaced ubuntu-advantage-tools with a no-op dummy package.

cmeerw ,

There is no reason to “hate” Ubuntu but there are better choices.

What are those better choices then (for those who currently use the non-LTS Ubuntu releases and don’t want to move to rolling releases or LTS-only releases)?

Can one recover from an accidental rm -rf of system directories by copying those files back in from a backup?

Well I’ve joined the “accidentally trashing your system with rm -rf” club! Luckily I didn’t delete my home directory with all the things I care about, but I did delete /boot and /usr, and maybe /var (long story, boils down to me trying to delete non-system directories named those but reflexively adding the slash in front...

cmeerw ,

Only issue is they’re stored in my server as belonging to the server user (I assume everything in those directories should belong to root and I can just use chown?) But I also don’t know if they retain the same permissions when backed up.

Not everything will be owned by root, and some of the binaries will be setuid or setgid, some might even have extended attributes (e.g. ping will usually have a security.capability attribute). /var will also have a lot of different owners.

The Paperweight Dilemma: Original Pinephone might lose future kernel updates if devs can't pay down tech debt (blog.mobian.org)

I think I’m reading this blogpost correctly: Mobian devs working on maintaining Linux kernel support for Pinephone painted themselves into a corner with tech debt, and may not be able to continue porting new kernel updates. Pinephone Pro runs a different chipset with wider community support, so it’s not affected....

cmeerw ,

And mainline Linux and a Linux Desktop is still struggling today with power management. Like getting chat messages while it’s asleep.

And the really sad thing is that the power management improvements devs have been working on for the PinePhone are really very specific to that particular device and don’t help mobile Linux in general (so it’s basically wasted effort).

I have had pretty good experience with hosting an email server on AlphaVPS, InceptionHosting and just now GreenCloudVPS.

GreenCloudVPS currently have a promotion until Sunday, and there are usually promotions around Black Friday on LowEndSpirit and LowEndTalk

I use them as IMAP storage for a few mailing lists I am subscribed to (but not for my main emails), but they do reject legitimate emails from time to time (not often, but it does happen - and those emails don’t show up in “Spam” or any logs).

cmeerw ,

Jed when you want a simple, Emacs-like editor.

cmeerw ,

How do they actually get that information (particularly memory utilization)? Do they rely on their agent that’s pre-installed (but can be uninstalled)? At least in their web interface it doesn’t show any of that utilization for my instances (one is Ubuntu with their agent uninstalled and the other one is NetBSD).

cmeerw ,

At least for memory usage the hypervisor wouldn’t be able to tell the difference between memory merely used as cache vs. memory actually used by the software running on the machine (and OSes will usually just use any otherwise unused memory as cache, so you will likely see some inflated memory usage)

Issue Tracking System for Linux (feddit.uk)

Hey gang! Looking for some recommendations on issue tracking software that I can run on Linux. Partly so that I can keep track of my hobby dev projects, partly so that I’ve got a bit more to talk about in interviews. My current workplace uses Jira, Trello and Asana for various different projects, which, eh, mostly serve their...

cmeerw ,

There is also Roundup Issue Tracker

cmeerw ,

I am actually using a OrangePiPC as:

  • WLAN access point (hostapd)
  • LTE Internet via a E3372 USB dongle
  • radio via DVB-T dongle/Internet
  • USB speakers for the radio
  • Bluetooth dongle to connect to Bluetooth-enabled speaker in another room
  • USB temperature sensor, motion sensors via GPIO
  • VoIP telephone with connected USB headset
  • small LCD display to show the current temperature and incoming call information

older laptop distro recommendarion

Recently I’ve gave up Windows for Linux and installed Ubuntu with KDE Plasma desktop on my pc and laptop from 2007. It’s an i7 Intel processor with 8gb ddr ram so I thought it would be fine, but it seems quite sluggish. What distro could I use that would be faster and still fully functional? Thanks for your help in advance.

cmeerw ,

You don’t really need to switch to a different distro. Just avoid snaps/flatpack/… and use a more lightweight desktop like XFCE and you should be fine.

cmeerw ,

Don’t believe everything you hear. It’s still available as a .deb: launchpad.net/~mozillateam/+archive/ubuntu/ppa

cmeerw ,

Was there even a change to the Firefox PPA? I am not seeing a change.

cmeerw ,

Verifying a snap package’s authenticity seems to suggest otherwise. What’s the source for your claim?

cmeerw ,

You mean like manpages.ubuntu.com/manpages/jammy/…/snap.8.html

Still better than a random user claiming

This is a massive security vulnerability

with no justification whatsoever.

cmeerw ,

But are they actually doing this? I am not seeing any changes: launchpad.net/~mozillateam/+archive/ubuntu/ppa still has the .deb packages

cmeerw ,

and newer versions won’t run due to library dependencies.

Mozilla seem to be able to limit library dependencies in their builds: www.mozilla.org/en-US/…/system-requirements/

cmeerw ,

Flatpaks can guarantee you have a known-good dependency chain directly tested by the developers/maintainers themselves

What does known-good mean? What if a security vulnerability is found in one of the dependencies. With an old-style distribution there is a security team that monitors security reports and they will provide a fixed package. With flatpaks it’s not clear to me if those developers will monitor each dependency for security vulnerabilities and how they will handle that. Will users even be informed about a security issue, will a fix be backported or will it only be available in the latest version?

cmeerw ,

Known-good meaning a tested and working configuration The bugs are fixed upstream and they get pushed via the method of distribution, which is Flathub in this case. Well, fixes don’t normally need to be backported because flatpaks are usually fresh.

There are a few assumptions in here in order for that to work: the known-good version needs to be the latest upstream version (otherwise you might not have the latest security fixes) and users need to be comfortable always using the latest flatpak version. Some users might be more comfortable staying on a known stable version for some time.

For notifications, you’d have to follow the relevant projects directly.

Right, and each project will have its own way of handling security issues (particularly when it comes to older versions). Will they point out that versions x - y of their flatpak are affected by a security issue in component z?

Been using phpwiki for the past 20 years or so.

And depending where you live that might or might not work out well for you. If too many people in your neighbourhood use too much mobile data at the same time as you, speeds will decrease and unlimited data plans in particular will be throttled.

cmeerw ,

If you really think about it, caps on mobile data are also fairly stupid

Mobile is a shared medium and can only support a certain amount of bandwidth per phone mast (in a certain area). A mobile phone network heavily relies on most users not using their data plans most of the time.

cmeerw ,

You can sue anyone for anything, but no one is advertising any guaranteed speeds for mobile broadband, so your chances will be fairly limited. Best you can do is withdrawing from your contract.

The description says:

In this video, we’ll do a deep dive on what C++ Polymorphism is, what “virtual” does under the hood, and ultimately why it is SUCH a performance hit compared to languages like C and Rust.

This is not about compile-time polymorphism.

That link appears to be for a Windows driver.

cmeerw ,

“they put ads in the terminal” isn’t really accurate.

Their “ubuntu-advantage-tools” adds information to one of their other products to the output of apt. You can easily get rid of that by uninstalling/replacing “ubuntu-advantage-tools”. It’s definitely not like they are selling ad space in your terminal to third parties.

cmeerw OP ,

I am using a single package from Mint, the rest is Ubuntu 23.04. Mint would otherwise be based on Ubuntu 22.04?

cmeerw OP ,

Mint would be based on Ubuntu 22.04, but I’d like to have something more up-to-date. I believe all other .deb based distros have the same issue that they are not as up-to-date as Ubuntu 23.04?

cmeerw OP ,

but it’s limited to Ubuntu LTS versions

cmeerw OP ,

How is only having an LTS version vs. having a choice between using an LTS version or a non-LTS version not a downside?

cmeerw OP ,

Sure, but what about your chromium builds? (as mentioned in my post, replacing the firefox snap with a firefox deb is easy enough on Ubuntu, chromium is the more difficult one to deal with)

cmeerw ,

XFS is 29 years old and certainly still in use as well.

cmeerw ,

I am actually running Tizen on a Samsung A5 - bit of a shame that no one else seems to be interested in Tizen…

cmeerw ,

In my case my main bank works exactly the same through the app than the browser mobile version

Main issue is that the two-factor authenticator app is usually only available for Android/iOS (some are still supporting SMS, but they are trying to phase that out)

WhatsApp

Their web app now actually works almost stand-alone. And as projects like yowsup have shown, it’s also possible to create your own stand-alone WhatsApp client (it’s only a matter of doing the work).

cmeerw ,

a single binary solution

but that means that it’s not using any OS-level privilege separation?

cmeerw ,

Ahh yes, but stalw.art/docs/configuration/general/ seems to suggest that it’s both single binary and single process.

cmeerw ,

I wonder if that could easily be fixed by just filtering the output of df to not show virtual disks (df already has an -l option to only show local disks, so would expect that changing df could be relatively easy).

Note: I am not saying that I like snaps…

cmeerw ,

lighttpd, just to be different

cmeerw ,

Anyone using groff? Seems like it just lives in its own little bubble?

cmeerw ,

Unused (or very rarely used) memory can also be swapped out to make more memory available for the disk cache (in the hope that having more disk cache available will save more disk accesses than the (hopefully one-time) swap-out operation).

cmeerw ,

They also used to have a MinimalCD, but that has been dropped after 20.04 IIRC.

cmeerw ,

just because it hasn’t been approved for GDPR

that’s not what the article actually says, and I don’t think any formal approval is needed anyway (you might get fined if you don’t comply with the GDPR). The article claims:
