Ok, I know this is outside of the norm for this page, I don't really care.

Backstory: I buy things from estate auctions on hi-bid. Nobody else bid on this so I got it for the minimum bid, $2.50 USD.

It was missing the hdd, and it was in a filthy barn.

Side note: auctions are generally "as-is, where is" that means you pick these items up at the location of the estate, they usually pull things out and organize them, but they don't clean them or anything usually.

I have an extra IDE HDD, so I threw that in and tried to install Windows XP. I got errors halfway through saying "setup cannot copy the file:"

Then I got it to go all the way through, but it won't boot.

Then I got a system error that the HDD is not present.

I tried an IDE adapted SSD, still not recognized.

Then I got the HDD recognized again.

I figured I would check the ram: 1x 256MB. I threw in 2x512MB, that's a neat trick.

I also swapped out the cd drive since it was having a hard time opening up anyway.

Now I'm back to, "setup cannot copy the file:"

Maybe a bad CD burn? Idk, it's been awhile since I've done this.

If you're looking for what might well be the most polished and user-friendly Linux distribution on the market, Zorin OS has a new release for you that covers all the bases.

Nitrux uses OpenRC instead of systemd, unlike most mainstream distros. It also features the Liquorix kernel, described as "an enthusiast Linux kernel designed for uncompromised responsiveness in interactive systems, enabling low latency in A/V production, and reduced frame time deviations in games."

New in this release is kboot, a utility to switch kernels on-the-fly without needing a reboot, and VMetal, which allows users to run Windows in parallel to Nitrux to provide users of access to Windows software.

I have a laptop with obsolete, licensed diagnostic software that I use on old equipment still in service. I've kept it alive longer than it should have been, but it's only a matter time before a disk or mobo failure puts me in a bad spot.

I'd like to make a clone of the current OS (Windows 10) as-is that could be run in VirtualBox or some other VM as a backup. Is it as simple as making a disk image with DD and then loading that up in VirtualBox? I'm sure it's not, but what am I overlooking? Or what other software would be better to use?

I'm fairly computer literate, but a mechanic by trade; So, not an expert.

Thanks for any help.

*or distribution

Having been a (GNU-)Linux user since 2006 (desktop only), I have done what many Linux users have also done: hop around from one thing to another.

That all stopped a few years ago when I decided that I would just stick with Debian. I was happy and comfortable. It worked. I used Stable, Testing, Unstable... no issues.

That is until about 4 months ago I was cleaning and found an older laptop and decided to try something different on it: Alpine Linux.

I even wrote about it on my blog. It was such a nice installation and process that I decided to put it on my main personal laptop.

Since April I have been using Alpine and I must say I am pleased. Differences from one Linux to the next aren't much to write about. With Alpine however, I finally experienced another part of Linux that I hadn't had the opportunity to enjoy: the community.

Package requesting? Easy. Asking for help? No shame. Patience and help provided? Excellent.

None of those comments are to disparage other OS communities. It is simply that I had only ever used popular distros (Debian- and Arch-based) so I never needed to ask for help. Either way, I am still using Alpine.

So, just to repeat the titular question: what have you tried out this year? What are your impressions?

I got this Chinese brand tablet pc and I'm positively surprised by it. Its a Dere T30 pro for those who are interested. I've been a Linux user for 20 years now so windows 11 is kinda new to me but I don't think I like it in the long run. I'm going to try to get Linux running on my tablet. So...What os or dm is best to use with a touchscreen?

Hello guys, thanks for the help and your time before starting.

My problem is this one:

I have Debian 12 installed onto my computer with 4 partitions:

Total disk is 466,6 GiB (~=500 GB)

• "/"           Size: 22,7 GiB  (42% used)

• "/tmp"        Size: 1,8 GiB  (6% used)

• "/var"        Size: 9,1 GiB  (84% used)

• "/home"       Size: 433 GiB  (12% used)

"/var" is almot full, with a 84% used, and I want to try to decrease that percentage. I've removed logs and all I could remove, but that percentage is still pretty high.

Searching around, I found that apps installed through Flatpack are stored in "/var/lib". This may be my problem? Is there any way to store Flatpack apps on "/home"

Solution -------

Thanks to @furrowsofar@beehaw.org and @heartlessevil@lemmy.one

To solve this I moved "/var/lib/flatpack" to "/home/user/..."

Then I softlinked the folder to its previous place with the next command:

ln -s [source || /home/user/.../flatpak] [Destination || /var/lib/]

I reduced the storage percentage to a 18,5% :D

Edit: corrections

Microsoft has released security updates for 130 vulnerabilities, including four that are known to be actively exploited.

The four actively exploited vulnerabilities are:

  • CVE-2023-32049: A Windows SmartScreen Security Feature Bypass vulnerability.
  • CVE-2023-35311: A Microsoft Outlook Security Feature Bypass vulnerability.
  • CVE-2023-32046: A Windows MSHTML Platform Elevation of Privilege (EoP) vulnerability.
  • CVE-2023-36874: A Windows Error Reporting Service Elevation of Privilege vulnerability.

Other vendors have also released security updates, including Adobe, Apple, Cisco, Fortinet, Google, MOVEit, Mozilla, SAP, and VMware. These updates are important to install as soon as possible to protect your systems from attack.

Other details:

  • The CVE-2023-32049 vulnerability can be exploited by tricking users into clicking on a malicious link. Once clicked, the link will bypass the Windows SmartScreen security warning and allow the attacker to execute arbitrary code on the victim's computer.
  • The CVE-2023-35311 vulnerability can be exploited by tricking users into opening a malicious Microsoft Outlook email. Once opened, the email will bypass the Microsoft Outlook security warning and allow the attacker to execute arbitrary code on the victim's computer.
  • The CVE-2023-32046 vulnerability can be exploited by tricking users into opening a malicious file. Once opened, the file will exploit the vulnerability and allow the attacker to gain elevated privileges on the victim's computer.
  • The CVE-2023-36874 vulnerability can be exploited by attackers who have local access to a victim's computer. Once exploited, the vulnerability will allow the attacker to gain administrator privileges on the victim's computer.

nice update for canary today. tl;dr:

  • the branch has switched back from zn_release to rs_prerelease & the dev semester is now gallium
  • all new features from moment 3/4 & dev have been foward-ported & re-enabled including:
    • dev drive
    • the new windows app sdk file explorer UI
    • windows backup
    • rgb lighting settings
    • passkey support
    • action center improvements (seconds on clock, new vpn experience)
    • emoji 15 support
  • rust code is actually (unlike the false alarm before) in the windows nt kernel now (gdi region, win32kbase_rs.sys)
  • 3d/gradient emojis are finally here (with a new emoji font format)
  • windows arm32 support is dead

A few friends recently commented that navigating the download page of Debian for the install media of their choice can be really tricky. I came up with this little gist to solve their frustration.

Hello fellow lemmers, who of you had a chance to install Cubeos and play around with it? is it something worth installing on a laptop, (assuming you have a beefy one). How does Cubeos treat Nvidia integrated graphics?

It's a textbook a friend recommended me, and it's great for learning the conceptual workings of an operating system, and it has practical knowledge alongside the conceptual. Code examples are written in C. If thou art interested in Operating Systems, this is a highly informative and interesting textbook thou shouldst check out!

As a basis for the post title, I used the thumbnail "title" instead of the somewhat clickbaity title Nick used for the video.

A trip down memory lane... QNX, a realtime microkernel surrounded by a collection of optional processes that provide POSIX- and UNIX-compatible system services.

I've seen a couple conversations about older or more esoteric operating systems, so I thought I'd make a post about 86Box and why I like the project.

86Box (a fork of PCem) is a low-level emulator for a wide variety of hardware from old PCs. Unlike most modern emulators which prioritize speed, it prioritizes accuracy of hardware emulation. This means it has all the quirks and features (and bios screens) you'd expect in old hardware.

It can emulate a variety of systems from the first IBM PC up to the Pentium era. It has a surprisingly large variety of motherboards, storage controllers, disk drive models, network cards, graphics cards, etc.

To test it out, I set up something close to my first PC:

  • 486 DX2 66
  • ASUS PVI-486SP3C Motherboard
  • S3 Trio64V+
  • 234MB 4500RPM HDD
  • Novell NE2000 ISA network card

I set it up with Dos 6.22, Windows 3.1, network drivers, mTCP, winpacket, trumpet winsock, and I'm on the internet in both dos and windows.

While something very similar could be accomplished with dosbox, virtualbox or qemu, I enjoyed the experience of using the 'actual' hardware. I also imagine it will support old quirky software more reliably than the alternatives.

I think a Windows 9x system with a 3dfx Voodoo card will be my next build.

So, Anyone else used 86Box or a similar emulator? What for? How did it go?

highlights:

  • windows copilot is now rolling out & replaces microsoft teams in the taskbar
  • settings has a new homepage
  • libarchive is in file explorer
  • the fluent volume mixer (introduced in canary a while back) is now in dev

For a long time I've been using Windows only on my private computer even though I might've wanted to use Windows.

One big part of that is that I have it set up next to my work computer when I'm working from home so I can do private stuff on it while working. Talking to people on Signal, Matrix, browsing Beehaw and so on. My work computer is pretty locked down and snooped on. I'm allowed do to stuff like that on it but it feels iffy.

Until recently I've used Mouse Without Worders to share the same mouse and keyboard between the two and it's worked like a charm.

I just never got around to checking for a solution that would work cross OS until today.

I've tried Logitech's solution once but couldn't get it to work due to firewalls and other stuff going on on my work computer but.. Barrier!

That just worked! I set up my private computer as the server and my work computer as the client and now I'm switching betwern the two machines without a glitch! :)

It did complain a bout a missing SSL cert at first but this solved that issue:

Copy the path to SSL directory which you can find in your error. "ERROR: ssl certificate doesn't exist: /home/rsvay/snap/barrier-kvm/2/.local/share/barrier/SSL/Barrier.pem " In this case : "/home/rsvay/snap/barrier-kvm/2/.local/share/barrier/SSL/" Then run the following commands:

cd  "path to your SSL"
mkdir -p Fingerprints
openssl req -x509 -nodes -days 365 -subj /CN=barrier -newkey rsa:4096 -keyout Barrier.pem -out Barrier.pem
openssl x509 -fingerprint -sha256 -noout -in Barrier.pem > Fingerprints/Local.txt
sed -e "s/.*=/v2:sha256:/" -i Fingerprints/Local.txt

It has been almost two years since the last ReactOS newsletter. Despite no new releases, the project is still active. Much work has been done on different parts of the operating system, from improvements on the 64-bit port to protections against registry corruption.

Rosenzweig, known for her Panfrost and Apple M1/M2 GPU driver work is now contracted by Valve to work on graphics driver development! Sounds like great news for Valve's push for Linux gaming.

I'm currently on Win11 but I'm getting that familiar Linux itch and want to dual boot a while again. I tend to gravitate towards Ubuntu simply because it's so big and well supported by most things.

I've run Arch in the past but I've gotten too old and lazy for that if I'd be completely honest. I have played with manjaro and endeavour though.. and opensuse tumbleweed, rolling is kind of nice.

Not sure what I'd try out first this time so I figured I'd get some inspiration from you guys!
