A long, long time ago, in a company no so far away…
Not too long ago, I picked up a Lenovo Thinkpad L440 laptop on eBay. It comes with Windows 10 Pro on it, but I could care less. I’m, obviously, going to install Linux on it because that’s my preferred platform. The question, now, is what flavor am I going to go with? Currently my desktop runs ArchLinux, which is great for keeping on the bleeding-edge. My ChromeBook-turned-LinuxBook is running GalliumOS because of the compatibility patches and packages that help make using the ChromeBook’s… unique hardware… less of a pain.
Moving forward, I think I’m going to give OpenSuSE a try. It’s been decades since I’ve used SuSE, and I imagine a massive amount of things have changed. They use KDE as the default environment, which I think will be a great Desktop Environment (DE) for the laptop, plus it’s very fast and generally lightweight. I honestly think I’m going to enjoy this a lot.
On top of this, OpenSuSE has a rolling-release distribution (similar to ArchLinux) in tandem with their more contemporary timed-release. Which means I can choose to be just as bleeding edge, but with OpenSuSE’s cool build server to get out of band packages.
The next few days are going to be exciting!
I have a small collection of scripts/Fish Shell functions that I use to ease the burden of getting things done. Not all of them are worth of a post, but I’d like to share what I have, because if it can help someone over a hurdle, then all the better.
Fetch from AUR
function aur -d "Fetch a package from AUR4" set -l projdir "/home/ndegruchy/Documents/AUR/" set -l appldir $projdir/$argv git clone https://aur.archlinux.org/$argv.git $projdir/$argv cd $appldir end
This particular snippet simply creates a new directory in my documents/AUR folder, then clones the specified AUR program to that directory, changing directory into it to make it faster to get up and building. I don’t have much use for this now, since I use pikaur to manage my AUR packages.
Blurred Screen Locker
#!/bin/bash IMAGE=/tmp/i3lock.png RES=1920x1080 ffmpeg -loglevel quiet -f x11grab -video_size $RES -y -i $DISPLAY -filter_complex "boxblur=10" -vframes 1 $IMAGE i3lock --image=$IMAGE --ignore-empty-password --show-failed-attempts rm $IMAGE
This bash script uses ffmpeg to take an X11 screenshot, and apply some blur to it before invoking my screen locker (i3lock), using the image as the image. Looks pretty nice and it doesn’t require much in the way of resources/tooling to get going.
function -d "Compresses and retitles my resume PDF" exiftool -Title="Nathan DeGruchy's Resume" main.pdf gs -sDEVICE=pdfwrite -dCompatibilityLevel=1.4 -dPDFSETTINGS=/printer -dNOPAUSE -dQUIET -dBATCH -sOutputFile=ndegruchy-resume.pdf main.pdf end
I often have several steps after I rebuild my resume out of LaTeX to make it ready for sending out. This Fish Function takes my resume, fixes the ‘title’ field, uses ghostscript to compress the whole thing and optimize it for screen reading. I should probably generate a Makefile for this to be honest…
So, it’s been another year and I’m getting better settled in to Linux. I’ve run through a lot of different window managers and desktop environments, like KDE, i3 and WindowMaker, before settling on DWM. Add to that more than a fair share of auxiliary programs to flesh out the experience and make things customized for me.
To that end, I’ve been trying to ensure that if anything should fail, I have a good backup to restore from. Enter Borg. It’s a command-line driven backup tool that not only compresses and encrypts the contents, but it de-duplicates it. This is fantastic for lots of little text files and the occasional photo set. The problem for me was, it was a lot of hassle feeding it all the options needed every time. Sure, I could alias it to make it simpler, but that still left a bit of work for me to do to get everything sorted, including un/mount the backup share, putting in a myriad of passwords, checking for number of incremental backups and pruning them so that I’m not dropping hundreds of gigabytes of useless, mostly similar backups (dedup’d or not) on my server, and on my offsite storage.
So, like most things on Linux, I glued all this together in a simple Fish Shell function. This allows me to just run a command (or add it as a user systemd timer) that backs everything I care about up, prunes and does all the drudgery of making a nice secure backup. Here’s my script/function that makes this all easier.
function my-backup -d "Mounts backup and runs borg" # Check for borg, first, bail out if it's not found if [ ! -x /usr/bin/borg ] echo "Borg not found, please install before running this script." exit 1 end # Check to see if the repo pass is available. We use this to avoid # typing passwords all the time set -x BORG_PASSCOMMAND "" set -x CURRENT_DIR (pwd) # What to back up # Home Dir Top Level set -x BACKUP_FILES Documents Pictures .config .local .gnupg .xsession # Home misc set -a BACKUP_FILES /home/ndegruchy/.local/share/Steam/userdata/9974372/ # Etc set -a BACKUP_FILES /etc/pacman.conf /etc/makepkg.conf # Emacs set -a BACKUP_FILES /usr/share/emacs/site-lisp/default.el # Package lists set -a BACKUP_FILES $MY_AUR_LIST $OFFICIAL_PACKAGE_LIST # Pacman package list backups, these are mine, the system will # (eventually) generate a full list at /etc/pkglist.txt echo "Exporting Pacman package lists" pacman -Qqem > $MY_AUR_LIST # Go home, for context cd ~ # Check to see if the backup share is mounted, if not mount it if [ ! -d /mnt/backups/degruchy ] echo "Mounting backup share to /mnt/backups/" echo "You will need your password to do this." sudo mount ... end echo "Trying to create a backup in /mnt/backups/degruchy with today's date and hostname." borg create --stats --progress --comment "New automated backup of critical stuff" --compression auto,lzma,6 /mnt/backups/degruchy::(date +%F)-(hostname) $BACKUP_FILES --exclude-from ~/.config/borg/exclude-file set -x IS_PHONE_PLUGGED (lsusb | grep -i "Apple" | wc -l) if [ $IS_PHONE_PLUGGED -gt 0 ] ## TODO: The phone data is copied locally, first, probably a ## good idea to check for available space, first. echo "Looks like your phone is plugged in, backing that up, too..." set -x PHONETEMP $HOME/.cache/temp/(date +%F)-nathans_phone mkdir $PHONETEMP idevicebackup2 backup $PHONETEMP borg create --stats --progress --comment "Nathan's Phone backup" --compression auto,lzma,6 /mnt/backups/iPhoneBackups/::(date +%F)-nathans_phone $PHONETEMP rm -rf $PHONETEMP end echo "Checking for backup prunability..." # Clean up old backups echo "Pruning..." borg prune --list --keep-daily 7 --keep-weekly 4 --keep-monthly 6 /mnt/backups/degruchy/ borg prune --list --keep-daily 7 --keep-weekly 4 --keep-monthly 6 /mnt/backups/iPhoneBackups/ echo "Unmounting backup.

Incredible ingenuity. Basically allows you to build a lightweight stove for next to nothing, available just about anywhere on the planet and one that you won’t cry over loosing, damaging or otherwise not having anymore.
I love these kinds of “life hacks”. Which is why I was so happy to find a whole subreddit of these things. I especially like travel ones, because travel is always such a pain when you want to carry what you need through airports and FSM-knows what else.
I think it might be time to build my own little group of life tips.
Nathan’s Computing Tips
- Don’t like having to remember complicated passwords? Try making silly sentences related the login you are creating. E.g.: “
Google me up a kipper!“. The punctuation helps keep the password complex, but is also easier for you to remember. You can also “mix” several words together to create one long string of gibberish that you can remember with just a mention of some random words.
- Want to let your friend use your computer? Look for a guest account feature. Windows and Mac have this feature built in, but disabled. Linux users… well, you know what to do.
- Want to save power on your cellphone at work? Turn on Airplane mode, then re-enable wireless (if you have wireless). Just tell your friends to call you at work if they need to.
- Rip DVDs to your computer for long trips. Saves power and reduces crap you have to carry.
- Back up your data. No. Seriously, if you read this list and only learn one tip, learn this one. Even if you just go out and buy a cheap external drive. Do it. This is especially handy if you need to get out of your house during an emergency and can’t take your desktop/laptop/whatever. Grab the drive and go.
- Need to use a scummy computer in a scummy place that you don’t trust? Download Tails (or any other Live Linux USB OS) to ensure that your communication online is from a trusted source. Though you can’t rule out hardware keyloggers.
