I would like to write some code behind GUI and have formatted document (which consists mostly of math expressions) as results of execution. My idea is: Python (backend), Qt5 (GUI) and Latex for building formatted documents. There are probably some libraries for Python-Latex interaction but do you know a better way to do this? Any ideas appreciated

WTF ... Mozilla had always running JavaScript inside PDFs disabled by default.

But now with FF 88 this option is ENABLED by default. Which means, if a PDF file contains JS it will run without any user interaction. What can possibly go wrong?

To disable this:

about:config
pdfjs.enableScripting --> false

# FF 78.10 ESR doesn't include this option and still blocks JS in PDFs by default. Just tested.

Linux Foundation has been quietly developing a project that might solve the supply chain attacks that are now on the rise - basically, a cryptographic transparency log of signed artifacts such as libraries, packages etc. It's in early phase but looks very promising

I got out of the hospital and my father should be out soon. I feel weak after covid and got some other complications such are increased pulse and diarrhea from antibiotics. Get vaccinated folks, don't be lazy or stupid, you don't need to waste your time and body.

I've been hospitalized with my father for a week now due to covid, we are getting better but time sure passes slowly when you are in hospital.

@nikolal Igor Pavlov (developer of 7zip) indicated in one comment that 7zip for Linux would have the same license it already has, LGPL. It seems he just didn't want to release the source yet in order to polish everything. After all 21.01 is an alpha version and there is also some trouble with compiling it on some platforms.

If you want good copy/write speeds with USB flash drives on both Windows and Linux machines format flash drive as btrfs and install WinBtrfs driver for Windows machine. There is no real need to make subvolumes, just format is important. WinBtrfs driver is open source: github.com/maharmstone/btrfs

Now that the new OnionShare has better command line support, I just wrote a guide explaining how to run your own anonymous Tor dropbox on a Raspberry Pi. Check it out: micahflee.com/2021/02/onionsha

If you have any leaks, load this URL in Tor Browser to send them my way: vxat6yszh7o5r2fxzvibxsb4lmfi6y

First time using ansible for Valheim dedicated server setup, very neat tool.

Has anyone been setting up Valheim dedicated server on linux? Where can I copy existing world to my server for me to connect to it?

This is a super interesting tool for organizing groups of people over #Signal:
signalboost.info/about/

(yes, the website is horrendous)

Enables broadcast or hotline service via Signal. This is different from regular Signal groups in important ways:
- broadcast: only the admins can send messages, which are sent to all users
- hotline: messages are only sent between a user and the admins who respond; nobody else gets them.

You can set-up your own:

Microsoft repository installed on all raspberry pies, you can switch to other OS other than Raspberry OS (previously Raspbian) or you can take other steps to remove it. Make sure somehow to notify Raspberry OS devs that this is not ok. More on this reddit post (from teddit mirror):
