A place where I capture raw, quick notes worth remembering.
This handy tweak lets you drag windows from anywhere on the window, not just the title bar. Perfect for when you’re working with windows that have minimal chrome or when the title bar is out of reach.
Hold Control + ⌘ and click anywhere on a window to drag it around.
To enable this behavior, run:
defaults write -g NSWindowShouldDragOnGesture -bool true
You’ll need to log out and back in for the change to take effect.
I switched back to Firefox because a web without ad blocking is unbearable. Yes, I could make it work again, but I want to support a more open web.
Turns out, the default Firefox could be much improved, with a few small tweaks.
First, let’s start with some more speed and security. Let’s install BetterFox. These are some optimized settings that others figured out for you.
Next, let’s use native theming on macOS. Go to about:config and set:
browser.theme.native-theme to truewidget.macos.titlebar-blend-mode.behind-window to trueFinally, I also switched to vertical tabs. You can find this option under “Browser Layout” in the settings.
There you go, a leaner, faster Firefox. Enjoy!
OpenAI pulled back a newly released model a while ago because it was too sycophantic. The new release was better, but I still get annoyed by how full of praise they often are.
Maybe it’s living in the Netherlands for so long, but sometimes I want an AI that will tell me when my thinking is sloppy, not one that congratulates me for having thoughts at all.
So, for some tasks, when I want to challenge my ideas, this is the prompt I use:
In all responses, prioritize intellectual rigor over social pleasantries. When I present ideas, probe their weaknesses, examine their underlying assumptions, and identify gaps in logic or evidence. Offer substantive counterarguments when you disagree, and when you do agree, explain your reasoning rather than simply affirming.
Challenge me to think more precisely about ambiguous terms, unsupported claims, or conclusions that don’t follow from premises. Point out potential blind spots in my perspective and suggest alternative frameworks for understanding the issue.
Your goal is to help me refine my thinking, not to make me feel good about my initial thoughts.
⚠️ Warning: this can make the model quite blunt, even rude. It called me an idiot more than once.
Here’s a handy tip: create Phoenix configurations that live only on your machine, not in version control.
I use this for setting machine-specific domain names. It’s ideal for any development settings that shouldn’t live in your shared repository.
First, add this snippet at the bottom of config.exs:
if File.exists?("#{__DIR__}/#{config_env()}.local.exs") do
import_config "#{config_env()}.local.exs"
end
Create a file named dev.local.exs and Phoenix will load it. Add this to your .gitignore to keep it local:
# Ignore local environment configs
*.local.exs
Your machine-specific settings won’t touch production or bother teammates. Common uses:
dev.localhost)Everyone on your team can customize their environment without stepping on each other’s toes. Enjoy!
yt-dlp is a powerful command-line tool for downloading videos from YouTube and other platforms. I frequently use it to save videos for offline viewing, particularly before long flights or to archive interesting content.
On macOS, you can install it using Homebrew:
brew install yt-dlp
Here’s the onfiguration that I use:
yt-dlp \
--cookies-from-browser safari
--format bestvideo+bestaudio
--merge-output-format mp4
-o "%(title)s.%(ext)s"
You can either supply these options through the command line or save them in a config file at ~/.config/yt-dlp/config. The config file format is straightforward - just list the flags one per line:
--cookies-from-browser safari
--format bestvideo+bestaudio
--merge-output-format mp4
-o "%(title)s.%(ext)s"
Once configured, downloading a video is as simple as:
yt-dlp https://youtube.com/watch?v=...
The video will download in the highest available quality and save to your current directory.
Want to save one keystroke and a few milliseconds? I’m trying something out, when I do my git commits, to start in insert mode, so I can start typing immediately.
You can do this by adding a new autocommand for git commit messages. In Neovim and Lua you create one like this:
vim.api.nvim_create_autocmd("FileType", {
pattern = "gitcommit",
callback = function()
vim.cmd("startinsert")
end,
})
If for example you are using Lazyvim, add the above to
your ~/.config/nvim/lua/config/autocmds.lua file.
Sometimes I’m working on a system and I want to reboot it, but I don’t want it to go to the default boot entry. E.g. I have Arch on my desktop, but it defaults to Windows so my kids can easily start the computer.
If you are using EFI, you can reboot into a specific boot entry, just one time.
First, show the boot entries that you currently have:
sudo efibootmgr -v
Then, pick the entry you want to reboot in:
sudo efibootmgr -n 0000
Now you can reboot, and it will boot into that specific entry.
Very often - like ALL the time - you end up creating a new directory with mkdir -p some_path and then immediately typing cd some_path right after. Such a waste of typing!
Here’s a super handy little function that does both things at once. Just drop this in your config and thank me later:
For Fish:
function mkcd
mkdir -p $argv[1]; and cd $argv[1]
end
For those that have to still learn that Fish is the best shell, here’s Bash and ZSH:
mkcd() {
mkdir -p "$1" && cd "$1"
}
Now you can just type mkcd ~/.config/test and boom - directory created and you’re already inside it! The -p flag means it’ll create any missing parent directories too, so you can go as deep as you want. Way better than typing two commands every single time, right?
While the standard ElixirLS installation works well for most developers, running it from source provides access to the latest features and improvements. Recently, after discussing this setup with a colleague, I realized others might benefit from learning how to implement this configuration.
Before proceeding, ensure you have Erlang and Elixir installed on your system. While I personally use Mise for version management, asdf works as well.
Begin by cloning the ElixirLS repository and installing its dependencies:
git clone [email protected]:elixir-lsp/elixir-ls.git
cd elixir-ls
mix deps.get
Next, compile and install ElixirLS. I recommend storing it in ~/.local/share for better organization. The installation commands vary slightly depending on your shell:
For Fish shell users:
env MIX_ENV=prod mix compile
env MIX_ENV=prod mix elixir_ls.release2 -o ~/.local/share/elixir-ls
For Bash or ZSH users:
MIX_ENV=prod mix compile
MIX_ENV=prod mix elixir_ls.release2 -o ~/.local/share/elixir-ls
After installation, the executables will be available in ~/.local/share/elixir-ls. You’ll need to configure your editor to use this installation.
For Zed, add the following to your configuration:
"lsp": {
"elixir-ls": {
"binary": {
"path": "/Users/<you>/.local/share/elixir-ls/language_server.sh"
}
}
}
elixirLS.languageServerOverridePath setting.To maintain the latest version of ElixirLS, simply pull the latest changes from the repository and recompile:
cd elixir-ls
git pull
MIX_ENV=prod mix compile
MIX_ENV=prod mix elixir_ls.release -o ~/.local/share/elixir-ls
This setup ensures you always have access to the most recent ElixirLS features and improvements while maintaining a clean, organized development environment.
So what’s the difference between == and === in Javascript? Nothing at all if the types on both ends are the same!
If they are different though, == will try to coerce, before compare and this is where a lot of confusion comes from.
42 == "42"; // true, "42" will be converted to number before comparison
1 == true; // true, because true will be converted to 1 before comparison
This also applies to relation comparisons like < and even <=.
There is no way to avoid coercion with relational comparisons. These are the only ones which are valid:
< (less than)> (greater than)<= (less than or equal to)>= (greater than or equal to)== (equality with coercion)=== (strict equality, no coercion)
