Elixir v1.20 released! Now officially a gradually typed language: Elixir type checks every single line of code, finding bugs and dead code, without developer overhead (no typing signatures) and extremely low false positives rate. Plus a faster compiler! Links and reports below.

Woot! The Tidewave gem for Rails has crossed 1M downloads: https://t.co/WK44NEvlmo

https://t.co/KNZbk8apeI is the best way to use coding agents for building web applications and we will have some more exciting updates soon! Give it a try!

[Brad Gessler @bradgessler]

Claude/Codex + Elixir + Phoenix + LiveView is such an insane superpower.

The entire stack, from low-level distributed systems modeling all the way up to the UI, is all built in one language & runtime that's easy to reason through.

pretty sure Anthropic CEO is having the best week of his life.

- Opus 4.8 released
- raised $65 billion at a $965 billion valuation
- $47B ARR vs OpenAI $25B
- officially BIGGER than OpenAI now

There's an Undo Send feature in Proton Mail btw.

You can set it to 0, 5, 10, or 20 seconds depending on how immediately you regret hitting send.

New in Claude Code (research preview): dynamic workflows.

Claude writes an orchestration script on the fly, then spins up a large fleet of coordinated subagents in parallel to take on your most complex tasks.

Use the word "workflow" in a prompt to get started.

I’m just 3 raccoons in a trench coat operating Claude at this point.

Elixir v1.20.0-rc.5 is out with our latest batch of typing and performance improvements. We are really close to the final release, so please give it a try and report what you find! https://t.co/8dWT2KdA5h

3 years using Claude every day.

Shipped production AI for 100K+ users.

The accelerant wasn't the model. It was a small library of prompts I refined into something I trust.

50 of them. $39 founders edition. https://t.co/RnFq5gCL7D

[Jared Smith @sublimecoder]

Drop this in Claude before you merge:

"Act as a Staff engineer reviewing for blast radius.
1. What depends on this path?
2. Worst realistic failure mode?
3. Reversible without backfill?
End: SAFE / MERGE WITH MITIGATION / HOLD."

New in Claude Code: agent view.

One list of all your sessions, available today as a research preview.

THIS GUY BUILT A PHYSICAL DEVICE THAT SITS ON YOUR DESK AND SHOWS YOUR CLAUDE CODE USAGE LIMITS IN REAL TIME

it's called clawdmeter. it runs on a $32 waveshare ESP32 dev board with a 480x480 AMOLED display

instead of checking the claude code UI or guessing how much usage you have left, you can now just glance at your desk

at this point anthropic should just mail these to us for free

but i also don't need MORE claude usage anxiety

AND it's open source on github.

this situation says EVERYTHING about the current state of the product

the claude code accessory market is booming in real time

The thing that's changed how I ship code isn't Cursor. It's not Copilot.

It's a small library of prompts I've refined into something I trust. 50 of them, $39, lifetime updates:

Most AI prompts read like junior devs wrote them.

Mine don't.

50 prompts I use as a staff level engineer. Code review, debugging, refactoring, system design, docs. Plus drop-in .cursorrules and CLAUDE.md starters.

We’ve agreed to a partnership with @SpaceX that will substantially increase our compute capacity.

This, along with our other recent compute deals, means that we’ve been able to increase our usage limits for Claude Code and the Claude API.
