Inactive RAID issue
6 June 2026 @ 4:18 pm
I've had a synology NAS that passed away leaving me with 3 btrfs drive in a RAID that I can't read anymore. I followed the synology tutorial but the output of cat /proc/mdstat was
Personalities :
md2 : inactive dm-2[2](S) dm-1[0](S) dm-0[1](S)
2761369344 blocks super 1.2
unused devices: <none>
And no output for lvs. So I tried mount /dev/md2 /home/user/backupNAS -o ro which gave me this :
mount: /home/user/backupNAS : can't read superblock on /dev/md2.
Also the result of lsblk is :
root@user-desktop:~# lsblk -o size,name,fstype,label,mountpoint
SIZE NAME FSTYPE LABEL MOUNTPOINT

How to install Guest Additions for AlmaLinux-10.2-aarch64-minimal inside VirtualBox on a MacBook Air (M5)?
6 June 2026 @ 11:12 am
I have inserted Guest Additions. I have installed needed packages such as kernel-headers perl etc etc. I have created a folder and tried to run:
sudo mount /dev/sr0 /mnt/cdrom
I then try to cd into the folder and
sudo ./VBoxLinuxAdditions.run
When I get
Detected unsupported arm64 machine type.
So I try to run the VBoxLinuxAdditions-arm64.run which I have in the cdrom folder, among other such files. Then I get:
Verifying archive integrity... 100% MD5 checksums are OK. All good.

WSL2 curl not working
3 June 2026 @ 7:56 pm
I have WSL2 installed on win 10. WSL is using ubuntu:
WSL version: 2.7.3.0
Kernel version: 6.6.114.1-1
WSLg version: 1.0.73
MSRDC version: 1.2.6676
Direct3D version: 1.611.1-81528511
DXCore version: 10.0.26100.1-240331-1435.ge-release
Windows version: 10.0.19045.6456
I rarely use it (another distro is being used by docker). I wanted to run a simple bash script and tried to run curl, but saw it hangs forever. I tried pinging some ips and domains and they all work, so ping is okay and network connections "seems" to be okay. but both curl and wget are hanging forever:
~$ curl stackoverflow.com -v
<nothing happens>>
or
~$ curl -v http://example.com

Why am I getting artifacts when daisy chaining monitors at 3840x2160 @ 120hz?
27 May 2026 @ 7:17 pm
I have my Dell U2725QE monitor connected to my Nvidia 5070 TI using a DisplayPort cable. I have then connected my Philips 279M1RV monitor to the DisplayPort output of the Dell monitor.
As seen in the manual of the Dell monitor on page 19, table 14 it does support 2 monitors at 3840*2160p, both running at 120hz.
However when doing so I get weird artifacts on my Philips monitor. It works great at 60hz and even at 98hz. Using the Philips monitor with a DisplayPort cable directly from the GPU works great as well up to 144hz.
What could the issue be?


Why are more and more Windows apps no longer working on Windows 10?
25 May 2026 @ 10:01 pm
About a month ago, I noticed that several Windows apps had stopped working. Among these apps was the Microsoft Store, as well as the Weather app and “Solitaire & Casual Games.” About a week later, the “Media Player” and “Game Bar” suddenly stopped working as well — even though these apps had been functioning just fine beforehand.
The problem affects only Windows apps. All other programs can be installed, run, and—if necessary—uninstalled without any issues.
All my research into the problem has yielded no results. I wanted to try repairing the apps, but that option isn't available to me. I only have the “Reset” option. I attempted to reset them, but I simply received an error message stating that the app could not be reset. Initially, the whole situation looked like a virus to me.
However, virus scans—conducted using both Windows Defender and a separate antivirus program (which I installed specifically for this scan, and which had help
How to automate multiple servers set up on virtual machine?
12 August 2025 @ 8:04 pm
I'm fairly new to Linux, VMs, and their automation. I'm using VMware Fusion, and I want to provision a Fedora server on it. When I do it with a single instance, it's rather straightforward: just fire up VMware, select the ISO image, then set up the hostname and static IP once the machine is up and running. But what if I'd like to set up multiple instances, which would only differ in a hostname and an IP address (assuming I want them to have static IP), and the rest (like users, default software, keys) is the same? I know there are tools like Ansible and Terraform, but from what I understand, those require the network to be already set up.
How is this achieved in a professional world? What tools are needed? Does this require a specific hypervisor that allows provisioning multiple instances at once?
Right now, the only thing that comes to my mind is a manual basic setup (e.g., for the network), and then the rest with Ansible. This is fine if I have 2 or 3 instances, but what if
Firefox says image download from iCloud contains a virus or malware
11 December 2024 @ 4:06 pm
I downloaded an image from iCloud, which ends up as a zip file containing a JPEG file and a MOV file. This is because the iPhone takes a motion image (MOV) over a brief interval of time, and then generates a JPEG still image.
Firefox complained that the file contained malware, which required me to explicitly allow the download. I then scanned it with with Windows Defender. All seems fine.
This seems to be due to some weird interaction between Firefox and Windows Defender. How is it possible for Firefox to get triggered by the download when the AV says it's fine?
After allowing the download, further picture downloads don't trigger the warning. From the Firefox download history, the message is "This file contains a virus or malware -- iCloud-content.com".
A further search reveals this.
Disable Microsoft Edge rounded corners
27 September 2023 @ 12:16 pm
I'm trying to remove the Microsoft Edge rounded corners feature (#edge-rounded-containers) in Experiments (edge://flags) for all my users on Windows 10/11.
It's also a toggle under Settings - Appearance, "Try the new look and feel of Microsoft Edge".
I need to find a way to run a script or something to patch Edge, but I can't seem to find any feasible solutions for that. Like, how do you script that? What's my best shot? Thank you so much!
