I just released a new major version of Cachex, my caching library for #Elixir: whitfin.io/blog/cachex-v4-0-…
This release includes several cool new internals and a whole list of optimizations 🎉
If you're interested, check it out and let me know your thoughts! #MyElixirStatus

Popcorn v1.0 is out! 🍿
It runs the latest Elixir and is fully compatible with the BEAM, because… it runs on the BEAM! It turns out that with a few tweaks, the BEAM fits in under 1 MB gzipped and runs just fine in your browser. Switching to it also brought major improvements in stability and performance.

On Sunday, colleagues from Erlang Solutions and Trifork UK walked 13 miles along the Thames Path in memory of Mark Cowan.
Together, we have raised £850 for Prostate Cancer Research. Thank you to everyone who walked, donated and shared Mark’s story.
Mark was determined to raise awareness of prostate cancer. It is the most common cancer in men, and early detection saves lives. If you have any concerns, speak to your GP.
You can still donate, here: justgiving.com/page/joanna-g…

I, for one, consider 4 a perfectly fine integer between 1 and 39402006196394479212279040100143613805079739270465446667946905279627659399113263569398956308152294913554433653942642

Right now someone is learning a tidy but wrong theory about your personal area of expertise.

I'm an avid user of coding agents, but there's something I've been struggling to put into words which I think is encapsulated well by these screenshots. these are two PRs to fix the same bug: the first is a +627 / -291 line change, from Claude, the second is a +3 / -2 line change, from Matt, a human (we closed the former and merged the latter).
there's a certain coherence in a human's mental model of the codebase which makes some bugs trivial for humans and still really difficult (or token-expensive) for agents. this goes beyond just better memory of the codebase. humans will build a mental map and a probability matrix for which parts of the codebase are most likely to surface a particular bug, given the codebase's coherence, and start by tackling those before going another layer deeper.
without matt's contribution we might well have merged the +627 / -291 PR, in turn losing coherence, and becoming more token-dependent as a result. after you lose coherence it's game over.
i've found myself pair programming with agents on tiny PRs after a huge amount of independent research / agent swarms to tackle a given problem, and I think this is pretty effective; you can combine the things that agents are naturally good at (parallelization, verifiable problems) with your human coherence. often this results in 15-20 PRs, not all of which get merged.

ok I think the main thing we've learned this month is that computer programs get faster whenever they're ported to another programming language, and all we need to do is keep porting back and forth until every program only needs one CPU cycle to finish

Maybe you're viscerally repelled by a nine-argument function, or a loop with a stack that could be a simple recursive function, or a deep class hierarchy that obscures rather than clarifies control flow. You don't have to think; the judgement just happens. That's fast and useful.

In the world of LLMs, there really is no excuse to not (at a minimum) put a product's Terms of Service into one and check if there are any obvious red flags.

We’ve got work to do. Geoff shares some more detail around where we missed with TFT’s engine migration and what we’re prioritizing in the road ahead.
