Your browser doesn't support HTML5 video. See? I’m really running NixOS. TL;DR Use the below provided flake.nix and set ~/.android/avd/phone.avd/config.ini hw.keyboard = yes to have a good Android emulator experience. Introduction It was an absolute nightmare but I finally managed to run both Android Mobile and Android TV emulators on NixOS without resorting to using a virtual machine. This blog post was super helpful in my quest. I literally just copied the flake.nix and the Android mobile emulator worked flawlessly. ...

TL;DR Why not Linux VM? Termux is way more reliable for keeping the SSH connection alive and it allows accessing other directories. Introduction In my previous post I talked about using Nix and Home Manager on my Pixel 6A. In this article I’ll share how to use a more “traditional” approach, i.e., using Termux with Cloudflare Tunnel. This is my current setup. Prerequisite Installed Termux, Termux:API and Termux:Boot and turn off battery optimization for them Enabled termux-setup-storage Set up openssh Possess a cloudflare domain for cloudflare tunnel Guide 1. Install cloudflared pkg update && pkg upgrade pkg install cloudflared 2. Configure cloudflared Note ~ is aliased to /data/data/com.termux/files/home Create the dir: cd ~ mkdir .cloudflared cd .cloudflared Set up the tunnel cloudflared tunnel login # follow the on-screen instruction cloudflared tunnel create pixel # create a tunnel called pixel cloudflared tunnel route dns pixel pixel.helloworld.com # create a route (`pixel` is the tunnel name; `helloworld.com` is the domain you own.) You should now have the following files in ~/.cloudflared: ...

Introduction Note This article is a good intro if you have no idea what I’m talking about. I use a Pixel 6A and I was surprised that I could run a Linux VM on it. Of course, I tried to use Nix on it. I found nixos-avf but it required Android 16+. I did not want to join the beta program so no NixOS for now. ...

TL;DR Use Distrobox when nixpkgs fails you or you don’t bother with declarative configuration. Introduction Never have I expected this much friction and frustration when switching to NixOS as my daily driver for development work. 1. Only nodejs 18 and above are available on nixpkgs I don’t get to choose what nodejs versions to use for work. For legacy projects I need nodejs 8, 14, 16 etc. The “oldest” compiled nodejs version available in nixpkgs is 18. I found Nix package versions but it requires compiling them from source. I can’t tell my boss “I’m compiling Nodejs 10 please wait 4 hours” before working on it. How I miss fnm. ...

TL;DR Use hop.nvim for leap.nvim-like bidirectional jumps but only for the current line. Introduction The search is finally over. I can have leap.nvim-like jump for the current line. Little did I know, hop.nvim is the plugin that does exactly what I want. Features Bidirectional jump. It means that regardless of the cursor location, I can jump to anywhere in the current line (leap.nvim default). I no longer need to remember to use f to jump forward and F to jump backwards. 2-character. The labels appear only after 2-character search (same as leap.nvim) My hop.nvim Configuration return { "smoka7/hop.nvim", event = "VeryLazy", opts = { keys = "jklasdfghqwertyuiopzxcvbnm", create_hl_autocmd = false, dim_unmatched = false, teasing = false, }, config = function(_, opts) vim.api.nvim_set_hl(0, "HopNextKey", { fg = "#000000", bg = "#CCFF88", bold = true }) local hop = require("hop") local keymap = { ["f"] = function() hop.hint_char2({ current_line_only = true, jump_on_sole_occurrence = false, }) end, ["t"] = function() hop.hint_char2({ current_line_only = true, jump_on_sole_occurrence = false, hint_offset = -1, }) end, } local modes = { "n", "x", "o" } for key, func in pairs(keymap) do vim.keymap.set(modes, key, func, { remap = true }) end hop.setup(opts) end, } With the field keys, I can almost guarantee that I can reach wherever I want in the current line with f{2-char}j. ...

TL;DR Download the Minimal ISO image and follow the Manual Installation to install librephoenix-nixos-config. I can’t stress this enough: DO NOT use any graphical ISO images like GNOME or Plasma Desktop! Use the Minimal ISO image not because we’re trying to be cool but because we want to make it work. Introduction If you think it’s as straightforward as installing Ubuntu, you’re in for a big surprise. There are so many gotchas along the way that I have to write it down for my future self, and hopefully for some other poor souls that stumble upon this article. ...

TL;DR Reverse split tunneling: ProtonVPN with WireGuard <– what I current use proton-privoxy <– what I used but broke one day forked protonvpn-cli-community Bonus: A dedicated app like browser/terminal routing through VPN: vopono Introduction I use ProtonVPN when connecting to api.openai.com.

I recently bought a chocofi and it took me days to figure out how to compile and flash my keymaps to it. Introduction Spec chocofi: low profile 36 keys split keyboard Controller: Sea Picro (USB-C, RP2040, 16MB, Black - no display) This Flashing Controllers is a very good introduction. With our controller being Sea Picro, we can’t just use qmk commands such as qmk compile -kb chocofi -km default, because it compiles to a hex file. ...
