HTML tips:

mailto, tel, sms: <a href="mailto:{email}.., <a href="tel:{phone}..
spellcheck attribute: <input type="text" id="input1" spellcheck="true">
sliders with type="range": `
clear button with type="search": `
pictures: source/img

<picture>
  <!-- load .webp image if supported -->
  <source srcset="logo.webp" type="image/webp">
  
  <!-- Fallback if `.webp` images or <picture> tag not supported by the browser. -->
  <img src="logo.png" alt="logo">
</picture>

Some tricks:

tabindex -meter,
ol-start,
datalist,
download attribute (<a href='path/to/file' download>),

Responsiveness on mobile to scroll on x

Copy to clipboard

in terminal:

pbcopy ~/.ssh/id_rsa.pub

in browser

function copyToClipboard(text) {
  navigator.clipboard.writeText(text);
}

JS

Instead of console.log(("number: ", number), do console.log({number}) !!
access to dataset:

<div id="user" data-name="John Doe" data-age="29" data-something="Some Data">
  John Doe
</div>

<script>
  const user = document.getElementById('user');
  console.log(user.dataset); 
  // { name: "John Doe", age: "29", something: "Some Data" }
  console.log(user.dataset.name); // "John Doe"
</script>

GenServer - memory posts, (GC - Garbage Collection)

A common pattern for handling memory-expensive operations inside a GenServer is to spawn a separate process to do the processing - this means the process itself does not grow extensively in size, and the memory used for the computation can be freed immediately (when the “operation” process terminates) - you could even consider starting the process with a bigger initial heap to eliminate GC completely (though, that might be risky and excessive without thorough measurement).

For example, this could look like this:

def handle_call(_req, from, state) do
  task = Task.async(fn ->
    # some computation
  end)
  {:reply, Task.await(task), state}
end

Or in case the response could be delivered asynchronously, even like this:

def handle_call(_req, from, state) do
  Task.start_link(fn ->
    # some computation
    GenServer.reply(from, reply)
  end)
  {:noreply, state}
end

:recon.bin_leak(10): :recon.bin_leaks(10) forces a garbage collect on all processes, and measures how many reference-counted binaries were freed per process.
hibernate:

def handle_call(req, _from, state) do
  ...do something with state
  {:noreply, next_state, :hibernate}
end
