The real reason to get a split keyboard 🧠

An office desk with two KRK studio monitors, a MacBook Pro and external display, a midi piano keyboard and split ergo keyboard, with Reason open for music making.

Phoenix LiveView 1.1 is an exciting release in a lot of ways, but the highlight for me is the JS is getting types! Huge thanks to the maintainers 💜 github.com/phoenixframe...

So I've mentioned that I'm working on a new library for extremely pluggable/composable LLM workflows, especially agentic ones. I'm getting closer to opening that up. One thing that underpins this is the ability to use NimbleOptions for function calling and structured outputs via JSONSchema. 1/2

I do not like the Notion API. I do not like it one bit.

Maybe the most amazing thing about Elixir to me pattern matching on binaries. Parsing a WAV file is almost as simple as writing down the file spec verbatim - look at this! #ElixirLang

Plaintext formatted to read as a table, outlining the WAV file specification. It reads:
```
WAV File Format Structure
------------------------

Position | Sample Value | Description
----------|-------------|-------------
1-4 | "RIFF" | Marks the file as a riff file. Characters are each 1 byte long.
5-8 | File size | Size of the overall file - 8 bytes, in bytes (32-bit integer).
| (integer) | Typically, you'd fill this in after creation.
9-12 | "WAVE" | File Type Header. For our purposes, it always equals "WAVE".
13-16 | "fmt " | Format chunk marker. Includes trailing null
17-20 | 16 | Length of format data as listed above
21-22 | 1 | Type of format (1 is PCM) - 2 byte integer
23-24 | 2 | Number of Channels - 2 byte integer
25-28 | 44100 | Sample Rate - 32 bit integer. Common values are 44100 (CD),
| | 48000 (DAT). Sample Rate = Number of Samples per second, or Hertz.
29-32 | 176400 | (Sample Rate * BitsPerSample * Channels) / 8
33-34 | 4 | (BitsPerSample * Channels) / 8
| | 1 - 8 bit mono
| | 2 - 8 bit stereo/16 bit mono
| | 4 - 16 bit stereo
35-36 | 16 | Bits per sample
37-40 | "data" | "data" chunk header. Marks the beginning of the data section.
41-44 | File size | Size of the data section.
| (data) |

Note: Sample values shown are for a 16-bit stereo source.
```

An Elixir code sample that showcases the power of pattern matching binaries as bitstrings - in this case for a WAV audio file. The code reads:
```
<<"RIFF",
chunk_size::little-size(32),
"WAVE",
"fmt ",
subchunk1_size::little-size(32),
audio_format::little-size(16),
num_channels::little-size(16),
sample_rate::little-size(32),
byte_rate::little-size(32),
block_align::little-size(16),
bits_per_sample::little-size(16),
data_chunk::binary>> = File.read!("./banger.wav")
```

Once #ElixirLang gets the type system I'll be making it rain $$$ every day.

Haskell got me interested in functional programming, Elixir got me functional programming. #ElixirLang

Apologies tw_screen_size friends, I only just noticed I've been making you uninstall to get your LiveView 1.0 upgrade - just released v1.1.0 to fix! #ElixirLang

Playing with React again after being away a while, pretty stoked about this setup: - @bun.sh serving @tanstack.com start + router - @biomejs.dev handling formatting, linting - @tailwindcss.com styles - Wasm with Rust + wasm-bindgen + wasm-pack - All dockerized and deployed to @fly.io Very slick ✨

Elm was the first functional lang I ever wrote a meaningful amount of code in. I convinced a professor at uni to let me use it instead of the recommended Angular.js for an assignment. It was great! Evan is a legend

Cloak is rad! I'm rebuilding my wife's website which handles some sensitive data. Last I checked, cloak_ecto doesn't support SQLite - but it didn't take much to do it myself 🔒 github.com/danielberkom...

Ecto schema with binary values, marked encrypted fields.

Working with LiveView everyday and still being tempted to rewrite all manner of things in Rust, Svelte, and [flavour of the month], has taught me your stack will never be shiny enough - just keep getting stuff done.
