Raspberry Pi 4 Not Accessible After a Reboot

Update: 28/12/2021 The solution? Move off the 64 bit Raspberry Pi OS and install Ubuntu. Everything below is now just for history and context :) Every time I update my Pi, whether it be an kernel update or due to something goofy I do, it refuses to be accessible via ssh after it boots back up. And everytime I bring it back to my desk, it just works. And when I put it back into its niche, by the door, it continues to work....

Getting Rid of Codliver Oil Burps

Don’t quite know when it began, but probably a sign of getting old 😂 I get nasty burps every time I take my codliver oil capsules now. Solution1 Buy capsules with what they call, an enteric coating on them. (Expensive! Not for me!) or Put your existing bottle in the freezer and pop one an hour before lunch. The combination of cold capsule ingestion, followed by its smothering by food an hour later, has fixed the burps for me!...

Basic Docker Image Management Pointers

Stuff for future Jason to take note, when he tries to redo his Huginn instance … I wanted a quick and easy way to install it, without messing up my base system much, so I chose the Docker route. Now, I don’t know the A or D of Docker, so these quick notes for me to remember in the future. I need to install Docker rootless, and bring it up as a systemd service....

Using Regex to Prepend to Titles in Calibre

So I do this peculiar thing, where I prepend the author’s initials to the title of every book I add to Calibre.1 2 And all these years, I’ve just been manually editing the metadata, everytime I added a book, and changing the titles to what I want. It’s not a problem if it’s just one book, but I normally tend to go hogwild with authors, normally buying out / downloading all their work....

Rough Notes on Swap File/Partition in Linux

Am using my rickety old laptop as my daily driver these days, because … reasons. And now, that I run PyCharm alongside Emacs, alongside Chrome in its various incarnations, the poor old thing crashes, freezes and stutters a lot. A cursory inspection told me that while I had plenty of CPU firepower, I was constantly running out of ram (8gb) and swap (1 gb partition). Too broke to add more ram to the system right now (don’t even know if this thing will support 8 gb modules to push it up to 16)....

Pycharm Does Not Recognise Compose Key Sequences

Did I not just write about this, the other day with Emacs? I did, but Pycharm seems to have the same affliction. Pycharm, just like Emacs, stubbornly refuses to accept my Compose key combinations. Which means … you guessed it, no ‘,”,“ or ’ punctuation and all the other affordances, Compose gives me. Considering that I need both, Pycharm as well as Emacs in my life, it behooved me, that I go solve this too....

Miniflux Service Fails to Start at Boot

Pleased as punch, with my Miniflux instance. RSS, is how I catch up with everything newsy and techy and with what people I want to hear from, have to say. I love it. I did face one teensy issue with it though. Every time I rebooted my machine, the Miniflux service would fail to start. I would just manually do a systemctl restart miniflux and it would start right up, with that innocent doggy face....

Stuffing variables into a config file for Miniflux

Something I learnt recently as I moved hosts for my Miniflux instance. I can just take all the variables I want (like feed refresh times, the base url or the address/port Miniflux listens on); and then stuff it into a config file and then launch miniflux like so … miniflux -c 'path/to/file' Pretty handy! P.S. The entire list of variables is here.

List Comprehensions, A Story in 3 Pictures

1. You take, this here list. 2. Chew on it. 3. And spit it out, just like a cow. I reposted this, because I called comprehensions, expressions in the older post. Sorry!
