So recently I have setup a mini NAS and I connect to it via an SMB share, but on nautilus I noticed that unlike my local files for the videos it would not create thumbnails when I was using nautilus (file manager for Gnome). The fix ended up being pretty simple 1: Nautilus > Preference > Show thumbnails. Set it to "On this computer only" for only seeing thumbnails on your system, . If u need it to do same for a remote server, select "All files" Or since we are managing this via NixOS and want to do things declaratively we can do do the following in our Nix config 2. ...

TIL - How to Change Emojis in nh Recently I have been trying to update the emojis when I run nh. Particularly the nom output. The old output was like so: To fix this update your nh derivation like so: environment.systemPackages = with pkgs; [ (pkgs.nh.override { nix-output-monitor = pkgs.nix-output-monitor.overrideAttrs (old: { postPatch = old.postPatch or "" + '' substituteInPlace lib/NOM/Print.hs \ --replace 'down = "↓"' 'down = "\xf072e"' \ --replace 'up = "↑"' 'up = "\xf0737"' \ --replace 'clock = "⏱"' 'clock = "\xf520"' \ --replace 'running = "⏵"' 'running = "\xf04b"' \ --replace 'done = "✔"' 'done = "\xf00c"' \ --replace 'todo = "⏸"' 'todo = "\xf04d"' \ --replace 'warning = "⚠"' 'warning = "\xf071"' \ --replace 'average = "∅"' 'average = "\xf1da"' \ --replace 'bigsum = "∑"' 'bigsum = "\xf04a0"' ''; }); }) ]; Note you will no longer be able to use the default nix cache to build this. So everytime nh updates you will need to manually build it. ...

TLDR; Add this attribute to your x-bind:hx-delete x-effect="currentItemId;htmx.process($el)" as an example (adjust for your example). Background In my app, I show the user 25 feedbacks per page, and they can delete them which opens a modal to confirm the action. If the user presses the delete button in the modal I want to send a HTTP DELETE request to an endpoint like /feedback/{id}, but the ID is dynamic, as we are using one modal for all the feedbacks vs having one modal per one feedback. ...

Recently I noticed when I searched using Telescope in Neovim, that I could see env.local.template but not .env.local. Where my keybinding looked like this: vim.keymap.set("n", "<leader>ff", function() builtin.find_files({ hidden = true, follow = true }) end, { desc = "Find all files" }) This was because I was ignoring the .env* paths in my gitignore, I could tell telescope to not follow the gitignore. But I would get a lot more junk when searching in Telescope. I just wanted to see certain patterns but still mostly respect the gitignore file. You can do the following: ...

Original Article You can find more context on the problem here In my post last month I thought I had fixed this issue but turns out I did not. The actual fix to stop getting this error: 5108: Error executing lua [string "v:lua"]:1: attempt to call global 'dropbar' (a nil value) stack traceback: [string "v:lua"]:1: in main chunk bat /home/haseeb/.local/share/nixCats-nvim/sessions/%2Fhome%2Fhaseeb%2Fprojects%2Fvoxicle.vim | rg dropbar setlocal winbar=%{%v:lua.dropbar()%} setlocal winbar=%{%v:lua.dropbar()%} setlocal winbar=%{%v:lua.dropbar()%} We want the winbar to nil. The fix that worked for me was this: ...

Actual Fix This fix didn’t actually work the actual fix can be found here I recently moved to dropbar from barbecue as it has been archived and kept getting a weird error for buffer open when I would reopen Neovim. I use the auto-session plugin, which loads back the previous state of NixVim when I last exited in that folder, i.e. open buffers. E5108: Error executing lua [string "v:lua"]:1: attempt to call global 'dropbar' (a nil value) stack traceback: [string "v:lua"]:1: in main chunk I noticed though I would only get this error the second time I would open Neovim, which then made think maybe it was an issue with auto-session. So I looked at the serialised file it generates so it knows what to load when we open Neovim again. Which I found at: ...

TIL: How to Cancel Stale Pipelines in GitLab CI Today I learnt that we can cancel old pipelines in MRs. For example, you push a new commit, and you don’t care about the old pipeline running any more. You want to cancel them to save CI minutes etc. Here is an example, you can see the 2nd pipeline is cancelled: We need to add this to our .gitlab-ci.yml file. Where the default.interruptible marks every job as it can be cancelled 1. ...

TIL: How to Get Shell Completions in Nix Shell With Direnv When shell completions don’t work with direnv, you may need to use nix develop to load the shell manually. Background I am using nix-direnv, with nix devshell to autoload into my development environments. I changed the directory and the devshell is automagically loaded without me doing anything, which is great. Provides me with a bunch of tools specific for that project. With all the benefits of Nix, mainly reproducibility. ...

TIL: How to Fix Did No Resolve Alias Errors in Podman Recently, I was trying to pull docker images using podman, on an Ubuntu laptop and was getting an error which looked something like: Error: error creating build container: short-name "node:18.17" did not resolve to an alias and no unqualified-search registries are defined in "/etc/containers/registries.conf" This is because Podman doesn’t allow us to use short names, by default we need to specify the registry i.e. docker.io/node:18.17. But for existing docker-compose.yml files, this would be a pain to edit. Especially because most people use Docker not Podman. So, in the end, you can edit a config file in home directory to enable the old way of pulling images. ...

TIL: How to Fix DNS Resolution Issues in K3s Related to Flannel Networking Recently, I was trying to set up the kubernetes-dashboard, to make it easier to monitor my k8s cluster. I however noticed I was getting the following error: … > add-kubernetes-dashboard via 🐹 v1.22.2 via  via ❄ impure (nix-shell-env) k$ kubectl logs -n monitoring kubernetes-dashboard-kong-75bb76dd5f-b27ll 2024/05/05 20:55:21 [error] 1319#0: *274054 [lua] init.lua:371: execute(): DNS resolution failed: failed to receive reply from UDP server 10.43.0.10:53: timeout.

TIL: How to Pull Submodules in a Nix Derivation Recently, I was trying to create a derivation which needed to pull git submodules as well. I was getting an error which look something like this: data/meson.build:76:0: ERROR: Nonexistent build file 'data/submodules/meson.build' It was coming from this derivation https://gitlab.com/hmajid2301/dotfiles/-/blob/c153de146a3bf9339cbef013ac65bc32e6305c8e/packages/gradience/default.nix for building the latest version of gradience. It turns out when we do a fetchFromGitHub we need to explicitly tell it to also pull submodules, which makes sense. So I was able to fix this. I had to add the fetchSubmodules argument: ...

TIL: How to Fix Neorg Metadata Tree Sitter Issues With NixVim If you are like me, you may be configuring your Neovim configuration using NixVim. Which is a “framework” making it easier to configure Neovim using mostly Nix configuration. Allowing us to keep most of our config in one language, at least in my case. I started using Neorg to manage my notes and to-do lists in my “second-brain”, but noticed that the metadata part was not being highlighted as I expected. ...

TIL: How to Set up Layouts in Zellij That Use Direnv and Nix I have been using Zellij for a while now. I tried to set up layouts for one of my personal projects. So that we could have tests and linting running and any other tasks we may want whilst doing development 1. However, I had an issue working out how to call commands that required direnv and nix to set up development environments. In my case, my nix dev shell installed the go-task tool to run tasks such as task lint or task tests. However the shell that zellij was running the commands in for the layout did not load my Nix dev shell, so the go-task binary was not available. ...

TIL: How to Get swaync to Play Nice With Waybar I added Sway Notification Center as my notification manager and added a small “widget” to my Waybar, so I can see how many notifications I have and silence notifications by clicking on it. However, I found when I opened the swaync sidebar, in my case by right-clicking on the icon. I found that I could not click on anything else on my Waybar like workspaces. Now I know I should be using my keyboard, but sometimes it’s just easier to use a mouse. ...

TIL: Clean Up Tmux Service When Removed by Home Manager Recently I stopped using tmux to try zellij, however I noticed when I removed tmux from my nix config. I was getting the following error, when rebuilding my home-manager config: The user systemd session is degraded: UNIT LOAD ACTIVE SUB DESCRIPTION ● tmux.service loaded failed failed tmux default session (detached) Legend: LOAD → Reflects whether the unit definition was properly loaded. ACTIVE → The high-level unit activation state, i.e. generalization of SUB. SUB → The low-level unit activation state, values depend on unit type. I was wondering where this error was coming from, turns it the symlink to tmux.service has not been deleted that nix would create. ...

Recently, I wanted to add a Neovim plugin to nixpkgs, so I can then add it to NixVim. I tried following the guide from the docs. However, I kept getting the following errors: nix-shell -p vimPluginsUpdater --run vim-plugins-updater error: … while calling the 'derivationStrict' builtin at /builtin/derivation.nix:9:12: (source not available) … while evaluating derivation 'shell' whose name attribute is located at /nix/store/whhzjfgalghpm34irclh01c0afynmyll-nixpkgs/nixpkgs/pkgs/stdenv/generic/make-derivation.nix:300:7 … while evaluating attribute 'buildInputs' of derivation 'shell' at /nix/store/whhzjfgalghpm34irclh01c0afynmyll-nixpkgs/nixpkgs/pkgs/stdenv/generic/make-derivation.nix:347:7: 346| depsHostHost = lib.elemAt (lib.elemAt dependencies 1) 0; 347| buildInputs = lib.elemAt (lib.elemAt dependencies 1) 1; | ^ 348| depsTargetTarget = lib.elemAt (lib.elemAt dependencies 2) 0; error: undefined variable 'vimPluginsUpdater' at «string»:1:107: 1| {...}@args: with import <nixpkgs> args; (pkgs.runCommandCC or pkgs.runCommand) "shell" { buildInputs = [ (vimPluginsUpdater) ]; } "" Or I was getting 429 network errors, too many requests to GitHub. ...

TIL: How to Fix Firefox Rendering Bug in Hyprland Recently, I had an issue with my Ubuntu laptop running Hyprland, when running Firefox it had this ugly border around it. Which looked something like this: You can see a weird border around the browser, and if you try to view some of the context menus, they appear small and difficult to read. Fix As per this Reddit thread 1. There are two fixes, one upgrade to version 0.33 which I could not easily do with Ubuntu. So I used the other fix, ...

Background Recently, I had to move one of my to-do files from its own repository, todo, to my second-brain repository. So I could better keep track of my ideas, and tasks to be done. However, I realised just copying the file over I would lose all the git history the file had. Strictly speaking, I don’t need the git history of that file, as the most important thing is the current tasks to be completed. I could, also, go look in the older repository if I really needed to see the file history. However, I decided it would be a nice exercise to learn how to copy files over and keep their history. ...

Recently, I was unable to change the location on my Mullvad VPN from other thing other than sweden. Even using the mullvad cli tool I would keep getting errors like: invalid argument for type conversion: missing custom lists settings it turned out to somehow a mismatch in versions where everything was running 2023.6 but my mullvad cli was using 2023.5. So I ended up fixing this by changing my config to: ...

TIL: How to Fix Verification Failed With Ventoy USB Recently, I tried to boot with my Ventoy USB on my new AMD motherboard Framework. However, I was getting a which looked like Verification failed:(0x1A) Security Violation. It turns out this was because secure boot was turned on. So we needed to turn it off initially to boot off the Ventoy. You can follow the instructions here. We can then turn on secure boot after, I will do a future post how we can do this with NixOS. When I get it working. ...

TIL: Show to Use the Media Keys on a ZSA Keyboard With Hyprland Recently, I started using a ZSA Voyager split keyboard, moving to this keyboard has some advantages but the last thing I felt I was missing from my old keyboard (which has a volume knob) was being able to control the volume. So I set up the key maps in their software (Oryx) however, I noticed that binding were not working. ...

TIL: How to Use Default Values in docker-compose.yml Sometimes we want to use env variables in our docker-compose files like so: services: client: image: ${CI_DEPENDENCY_PROXY_GROUP_IMAGE_PREFIX}/nginx ports: - 8000:80 Here we are going to use the GitLab CI dependency proxy to pull our Nginx image, so we can speed up our pipelines but also avoid being rate limited by docker hub. However, when running this locally, we will need to make sure the CI_DEPENDENCY_PROXY_GROUP_IMAGE_PREFIX env variable is set. Which just adds a bit more work, instead we can leverage some of the special syntax docker-compose provides 1, which I think it inherits from bash. ...

TIL: How to Use Open Buffers When Debugging With Neovim’s DAP Plugin I had an issue that whilst debugging my Golang tests in Neovim, the buffer I was focusing on would always change to the breakpoint. Even when the buffer was open and visible already, say I had the code with the breakpoint on the left buffer and the tests I was starting the debugger from on the right buffer. ...

TIL: How to NTFS Drive on NixOS Recently, I was trying to open an NTFS drive on my NixOS machine; however, the drive was corrupted. So I did the following to fix the drive. nix-shell -p ntfs3g ntfsfix /dev/sda1 Where /dev/sda1 is the broken drive. This was enough for me to be able to mount the drive and access the files on it. I didn’t need to fix it on a Window machine. ...

TIL: How to Append to a Config Option String in Nix Recently on my laptop I had to add some extra config settings to my Hyprland config. Rather than polluting my hyprland.nix file with if, else depending on the host. I wanted to add the extra config in the home.nix of the host. So it’s contained within that host. Where my home.nix is the entry point for my home-manager config for that host. ...
