  • No! Bad dev! No biscuit!

    Never merge master into a feature branch. It’s called a “wrong-way” merge and it makes the history fucking awful.

    You shit in the face of project maintainers when you do this.

    You may not care, in fact many don’t. Also people buy timeshares, read celebrity gossip magazines, and vote for scumbags. They are fucking idiots who don’t know what they are doing. So are people who leave wrong-way merges in shared history.

    In fact, wrong-way mergers are worse, because you can’t just ignore them - git blame rubs your face in their shit, so they shit in your face forever.

    Just don’t fucking do it, OK? Or I will hit you in the throat with a cricket bat soaked in wasps. As a first warning.




  • Implementation of VPN’d torrent client

    This is how I torrent over Mullvad. I have no hesitation to recommend Mullvad - but I am not a crypto or security expert.

    The main image fails closed - if the VPN goes down, transmission disconnects.

    This setup also includes a SOCKS server that proxies your traffic over the same VPN. I use a separate browser (librewolf) and set the SOCKS proxy to :2020 including sending DNS over SOCKS. That’s because my country blocks piracy-related sites at the DNS level. If you don’t need this, you can delete the socks section of the docker-compose file.

    On my ubuntu laptop, I install transmission-remote-gtk in order to click on a magnet link and have it added. Otherwise you have to browse to the container’s web interface, which gets tiresome.

    I have this installed as a systemd service so it runs on boot. I use the systemd state and credential features as a safeguard against my own mistakes with permissions, but my long-term goal is to encrypt these files on disk. Linux can be pwned - I have read that around 35% of botnet nodes are linux (although these are presumably mostly weak IoT devices). The secondary benefit of the LoadCredential/CREDENTIALS_DIRECTORY mechanism is that it doesn’t expose secrets as environment variables.

    The p2p.service file needs to be in that path, but you can put the other files wherever you want.

    Known issues / todo list

    • The socks proxy sometimes falls over, I haven’t looked into why
    • The downloaded files will be owned by root, since that’s what the container runs as

    File contents

    /root/.secrets/mullvad:

    123456789
    ""
    

    For mullvad, there is no password, only an account number. I believe that the empty quotes are necessary. This file should be owned by root and chmod 600; containing dir should be 700. Replace the account number with your own account, obvs!

    Steps

    1. Install docker and docker-compose, e.g. with sudo apt-get install -y docker-ce docker-ce-cli containerd.io docker-buildx-plugin docker-compose-plugin
    2. Create the files with contents as above
    3. sudo systemctl enable p2p
    4. sudo systemctl start p2p
    5. Check what it’s doing: systemctl status p2p
    6. On first start, it will take a few minutes to pull the images
    7. To debug interactively while also passing the creds, use sudo systemd-run -P --wait -p LoadCredential=mullvad:/root/.secrets/mullvad docker compose up --remove-orphans
    8. Every so often, cd into /usr/local/bin/p2p and run docker compose pull to update the images.

    Racial origins of those terms? Citation needed.

    Black and white, in the sense of good and evil, have had their connotations for a fucking long time, whereas black and white to describe skin colour are relatively recent etymologies. I’m pretty sure that Romans didn’t call themselves “white” or others “black”, for example.

    I’m willing to be taught, but this sounds like bullshit to me.

    The etymology being wrong doesn’t mean that we shouldn’t drop freighted terminology, I just don’t want false justification. Bullshit is never a valid reason to do something.


  • Pure FUD. Worse, it’s wilfully stupid.

    Are you in the habit of picking pipeline commands at random? Do you not usually have a purpose in mind? OBVIOUSLY the receiving end has to understand what it’s receiving, or what the fuck are you even doing?

    Do you believe that your text processing commands don’t have to understand what they receive?

    Let’s get the ports of the node container.

    Bash:

    docker ps | grep node | cut -n 6 -f ' '
    

    Pwsh:

    docker-ps | where name -eq 'node' | select ports
    

    First the grep command shits the bed because at some point you started a new container running a nodejs image.

    Then the cut command fails because you had a container with a space in the name, so it outputs mounts instead of ports.

    That’s a non-issue with sematic tools. Semantic tools are also legible. Yeah, I can figure out what that awk command does, but it’s meaningless unless I also know the shape of the data is supposed to operate on.

    You don’t write “USE 2nd DATABASE; SELECT 3rd COLUMN FROM 10th ROW”, do you? Why would you want to do that in a shell?




  • My understanding is that the Windows terminal sucks? I don’t know why, it just looks bad.

    Your understanding is wrong. I’ve tried 8 different terminals on mac, arch and kubuntu, and I miss Windows Terminal every day. It looks good and the config is a pleasure. I don’t expect Linux to look pretty, but MacOS had fucking awful font rendering and it’s supposed to be this upmarket OS for moneyed pricks in black turtlenecks. Was everyone in unixland busy doing drugs while Microsoft was implementing anti-aliasing? Is clear legible type for losers?




  • I did not find that at all.

    I’m sorry you have that - I didn’t. I was quit with no cravings for five years, what got me back in was spliffs with tobacco. (Now I vape, because I do intend to occasionally smoke weed with tobacco.)

    The reason you still have cravings is because you never deprogrammed yourself. You still associate gaspers with relief, relaxation, pleasure.

    If you can reframe the sensation of smoking as the tense tickly feeling of “god I could use a fag”, which no-one would claim to enjoy, the rest is plain sailing, and within a few weeks you’ll be past any cravings. The bulk of the cravings are done within a few days.

    I don’t mean to suggest that it’s easy to quit - most people fail. But the trick is not too withstand cravings for the rest of your life, it’s too break the paradoxical association of fags with pleasure, which is a one-time thing.
