If you ever wanted to chroot into the generated initramfs here are the steps. I thought it was interesting so wanted to share.

mkdir -p /mnt/initramfs
cd $_
lsinitcpio -x /boot/initramfs-linux.img
mount --bind /proc ./proc
mount --bind /sys ./sys
mount --bind /dev ./dev
SHELL=/bin/ash chroot .

Can someone explain why this would make the command wait forever? What is tee waiting for?

echo "test" | sudo tee newfile

What would be a scriptable workaround for such cases?

Edit: this command would not terminate in zsh. This works fine in bash tho.

Do anyone know how to disable the touchscreen on wayland? All I find is only relevant for x11

I'm looking for a simple remote system monitoring and alerting tool. Nothing fancy. Do you know of any? Features:

• monitors CPU, memory and disk space
• can accept multiple hosts to watch
• has some sort of alerting system
• can be deployed as a single docker container
• can be configured using a text file
• configs can be imported and exported inside the docker compose file

I like uptime-kuma but it only records the uptime. Other containers I've found seemed to be overly complicated. They requires multiple docker containers for log aggregation etc...

In every country there are several mobile service providers. And with current EU regulations no mobile provider can charge extra for traveling within EU. Mobile providers in my country are definitely more expensive that average European mobile plan. I was wondering, can I downgrade my current plan to only keep my current phone number and purchase a plan from a cheaper mobile provider in another EU country with unlimited data and just use roaming all the time since I'm in EU? What are your thoughts? Do you know about a cheap mobile data plan?

I'm in the process of starting a proper backup solution however over the years I've had a few copy-paste home directory from different systems as a quick and dirty solution. Now I have to pay my technical debt and remove the duplicates. I'm looking for a deduplication tool.

• accept a destination directory
• source locations should be deleted after the operation
• if files content is the same then delete the redundant copy
• if files content is different, move and change the name to avoid name collision I tried doing it in nautilus but it does not look at the files content, only the file name. Eg if two photos have the same content but different name then it will also create a redundant copy.

Edit: Some comments suggested using btrfs' feature duperemove. This will replace the same file content with points to the same location. This is not what I intend, I intend to remove the redundant files completely.

Edit 2: Another quite cool solution is to use hardlinks. It will replace all occurances of the same data with a hardlink. Then the redundant directories can be traversed and whatever is a link can be deleted. The remaining files will be unique. I'm not going for this myself as I don't trust my self to write a bug free implementation.

I've run passwd and sudo su; passwd to change password for root and my account. Password is set correctly when using sudo and su but whenever I get prompted by pkexec it accepts only the old password. I've rebooted my system to make sure it was not an issue.

Edit: Solved Turns out the password were changed for root account but not my user account. I think the reason is that there are no password quality requirements on root accounts, but there are on the default account in ubuntu. Changing the password from root account passwd user worked fine.

while true; do; sudo pacman -Syu --noconfirm; done

It is common for companies to neglect financing in cyber security for a quick short term gain. And at the same time the laws are created such that an offensive hacker would be the criminal. By turning the law around the blame would be on the company for building insecure systems, just like it is right now companies get problems if they would create unsafe products for consumers.

What do you think would happen if laws would change in such a way, that gaining unauthorized access would become legal? Note that I've intentionally excluded permission to share sensitive information. Would love to read your responses and thoughts

I've picked up an old MacBook air 2013 from trash without battery and ssd. I want to see if I can bring it back to life. Apparently Apple does not use standard SSD. Do you know about any adapters in the market that would make it possible to use a standard SSD? I don't want to spend money on non standard SSDs that works only on macs. I don't even know if it work even at this point.

Hi, what do you use to cooperate on simulink projects? I tried using git on GitHub at first but the issue is that GitHub has a size limitation on blobs. It suggested to use git-lfs however that filled the storage space up almost instantly. is there any other solutions you've found useful?

has anyone had any success with squad 6.0 yet?

I'm looking for an extension that makes the workspace on multi monitor setup independent. Right now If I switch workspace on my laptop it changes on the big screen as well.

In my dmesg logs I get following errors a lot:

What properties that affect the range, speed and features should a consumer be looking out for?

I've been messing with my flash drives trying to follow some random documentation with dd and now both of my flash drives are reporting 0 bytes of free space. I was trying to clear out everything and start from scratch as if they were new. I wonder if there are any program out there that can just sudo reset-everything /dev/sdX

I'm experiencing an issue with commands that provide a tui interface like journalctl, systemctl and vim. It feels like terminal dimensions are not matching up somehow. And this issue is present only some times. On host I'm using Black Box and I tile my windows using pop os tiler. I'm also frequently scaling the font with ctrl + and ctrl - shortcuts. Remote sshd host is running Debian variables $LINES and $COLUMNS are set. bashrc files are in their default state.

How is this supposed to work? Isn't my terminal client sending new $LINES and $COLUMNS each time there is a change?

Do you know about a private customizable search engine? I would like to hint the search engine about what search results I like without specifying them on every single query.

For instance when need to search up some programming documentation almost always there are some blogs in the search results meanwhile I'm always looking for the official documentation. I want to go to settings and specify something like

+ official documentation
- blog

and every single time I search something up I get less noise. Also being able to block some domains like

geekforgeeks.org
learn.microsoft.com

would also be nice. In case I get annoyed by some domain that have a lot of ads and information at the very bottom.
