A cheat sheet leading to success with NVIDIA drivers on Fedora 43+ on a Precision 7560 Mobile Workstation:

Do not use official NVIDIA driver installer.

Do not blacklist noveau:

sudo grubby --args="rd.driver.blacklist='' modprobe.blacklist=''" --update-kernel=ALL

Do not install v4l2loopback/git from git:

sudo dkms uninstall v4l2loopback/git

Just install akmod-nvidia:

sudo dnf install akmod-nvidia xorg-x11-drv-nvidia-cuda

Wait 5 minutes until modprobe, reboot.

Here you go. Nice and easy.

The maker tools are unproductive on purpose. Nobody expects your Arduino project to ship to customers. Nobody expects your homebrew computer to compete with IBM.

The whole point is that you have the permission to fuck around, and the finding-out happened gradually, through play, over years.

This is where the old Silicon Valley adage comes from: “What smart people do on the weekends, everyone else will do during the week in ten years.”

Vibe coding broke this pattern.

Open internet is replaced by consumption platforms, whose business model requires passive engagement. A user who spends X hours going down a tech rabbit hole, breaking things in a terminal is worth less to them than a user who watches X hours of content. They don’t ban tech material. They algorithmically deprioritize anything that demands active engagement and reward passive consumption.

This culture treats passive consumption as the default relationship with technology. https://fireborn.mataroa.blog/blog/the-slow-death-of-the-power-user/

Few days earlier I've learned that, thanks to our 3D-printed part deliveries from @hamlab@wtf.lt , an Ukrainian🇺🇦 platoon stood their ground firmly somewhere near Sumy.

So I am certain we will stand our ground together. On some other social networks I would be attacked by bots for this post, but here I only expect authentic vatniks :)

@mkj@social.mkj.earth Having said that, for each direct connection (where I would like to reach the destination directly, not through WG), I have to supply a static route for that destination where the gateway is the local network router, correct?

Is there anything illegal to have your default route pointing not to your network gateway but to the #wireguard peer local IP address? Like, on the router level?

Lets have a pair of Wireguard IP's: 10.0.0.2 is me and 10.0.0.1 is my WG endpoint.

The network gateway (B) is only used to reach the public peer IP address (A) and that's it:

ip route add A.A.A.A/32 via B.B.B.B

Your whole traffic up until your trusted Wireguard endpoint somewhere is encrypted:

ip route add 0.0.0.0/0 via 10.0.0.1

🤔

A project aimed to join together the scattered #Linux communities in #Lithuania seems to take shape. One pull request will soon add a new upcoming event, so stay tuned: https://linux-lt.org/ (soon-to-be linux.lt) @vaidas@river.group.lt your turn :)

Ham radio, also known as amateur radio, is a fascinating hobby.

Ham radio enthusiasts can communicate with others around the world, including astronauts in space.

Many ham radio operators enjoy building and experimenting with radio equipment.

Ham radio can involve writing software, developing new technology, and more.

Ham radio operators can participate in contesting, which some call the "Radio Sport".

Please boost/share if this sounds interesting.
