Figure 1: The laptop that was having a bad day with NixOS 23.11 More upgrade gotchas. Shucks. If everything goes well, this will be my last NixOS post. Read on to understand my frustration just a little bit more. My main laptop is a Lenovo Ideapad Flex 5 — simple and cheap device. The keyboard stopped working in the early boot after upgrading to 23.11. The impact: I need to a USB keyboard around to unlock the device from a cold boot.
Figure 1: Jamian · CC BY 3.0 Deed (link) A frequent quip of the unix-beard is shebangs cannot contain multiple command-line arguments. Let’s break it down and see where this assumption no longer holds true. What is a Shebang? The shebang is the line at the beginning scripts such as Python and Shell scripts that instructs the OS how to execute the script. Looks something like #!/bin/sh or #!/usr/bin/env python.
Figure 1: Official image for 23.11 Upgrading my workstation to 23.11 wasn’t as simple as I was hoping. Ran into a few issues. Performing the upgrade I’m using a flake, so all I should have to run is: # First edit flake.nix so it points to release-23.11. nix flake update nixos-rebuild boot --flake .# (Then systemctl reboot into the new generation that includes a new kernel.) Issue #1: pinentry package changes I can’t unlock any keys using gpg-agent (hence cannot use GPG keys for accessing my password database and send signed documents).
I’ve been using Nix for a year now. It’s been going fairly well, by the way. Here are some misconceptions I’ve had to overcome to become a more productive Nixer. False: You can’t deploy Nix software to Docker or Kubernetes False. If you can push to a docker registry such as docker.io, you can deploy to Docker or Kubernetes using Nix. You can use dockerTools.buildImage to build a docker image from Nix.
Source lives here. Play it here. In a joint effort, Aliasing and myself have created a novel top-down action rogue-lite for the 2023 Spring Lisp Game Jam. Aliasing is an experienced game dev so in a way, I was along for the ride. Still, I managed to contribute some game mechanics, features, unit testing, CI/CD that deploys to super-rogue.workinprogress.top on every commit. This was a fun devops exercise for me - Aliasing mentioned to me that I helped keep him on track with the addition of automated testing and per-commit deploys to a website (it makes it easy to play-test pull requests).
I’ve been operating Sillypaste (source code) - a simple Django pastebin created for dogfooding. In this post I hope to capture some of the painpoints of working with Django, Python, Heroku, and the migration to fly.io. Ever since Heroku sold its soul to SalesForce its been on the decline. Customer service is worse than ever, giving wonderful canned responses to most questions. It used to be free to host Sillypaste on heroku, now is a $17/mo ordeal.
Figure 1: your computer on low memory TL;DR: yes. You can throw more swap at most processes and it’ll eventually finish… Eventually. Last year I warranty-ed a Dell XPS 13 with 32 GiB of RAM, all specced out. Sidenote: I wouldn’t recommend the Dell XPS 13, at least in 4K. The laptop gets anywhere from 1-3 hours of real world usage and gets hot as most Macbooks. The Dell XPS 13 4K is not a viable product.
