Phoenix with Elixir is for sure "a better Rails". Although that's really selling it short - it's so much more than that! But in the context of this conversation, it's a good place …

This is one of those things where I don’t agree with the argument, but know the person making it knows way more than I do on the subject and has given it way more thought. In these…

The part of the Polgár story that amazes me the most is that all three daughters showed enough interest and engagement in chess for the experiment to work so successfully. Because …

A bullet-point list of ways you screwed up communicates something entirely different than a long form email filled with flowery "fluff" (as the author puts it). In fact, if the aut…

Looking back, they were both right!

I fully agree with the sentiment, and yet marvel at the apparent lack of alternatives for so many business models. I'm mildly surprised, for example, that micro-payments for web co…

I think this argument only makes sense if you believe that AGI and/or unbounded AI agents are "right around the corner". For sure, we will progress in that direction, but when and …

I see this post getting trashed in the comments for its overly literal interpretation of personality as a reinforcement learning process, but I think there's some value to it as a …

Yes, I was surprised to see that there is no mention of the Anthropic Principle ( https://en.wikipedia.org/wiki/Anthropic_principle ), which describes exactly what you're saying. O…

But that's for 2026 - the 2025 time qualifying time is 3:00.

I'm not sure... I'm a huge Elixir fan and I trust José to build a great solution, but I've found the rollout to be a bit confusing. There was the announcement that "Elixir is now a…

Great post, but kind of buries the lede: PostHog is having a CrowdStrike moment.

One interesting note on this approach is that the author suggests using a "fast" sorting algorithm like mergesort/quicksort as the sorting algorithm for best performance. But in pr…

Right - the word "hallucination" is used a lot like the word "weed" - it's a made-up thing I don't want, rather than a made-up thing I do want.

Good call - I think you're right about IEx trapping the exit. The confusing part is that it still logs out this message: ** (exit) exited in: Task.await(%Task{mfa: {:erlang, :apply…

Good thoughts, but the printing continues indefinitely, and the documentation for Task.await explicitly says the child process will be killed: "If the timeout is exceeded, then the…

This post got me curious about similar scenarios in Elixir, and despite working with Elixir every day, I'm a bit surprised by one of the results I found: # Recursive function that …

I would guess that 80% (or more) of those 80% would rather not change their entire world view.

The "healthy user bias" is a well-known phenomenon in this kind of research, and has been studied specifically with vegetarianism (for example, https://journals.lww.com/nutritionto…

I'm not going to argue for or against any specific conclusion here, but there are several reasons that observational nutrition studies (and reviews of such work, like this one) nee…

The attitude is perhaps not surprising from a community whose unofficial tagline is "Rewrite it in Rust".

This is great. LiveView is truly amazing and greatly speeds up development, but as the post describes, there are a couple of rough edges. They're all solvable, but sometimes there …

Can we start a list of technological magic that is actually "1000 people in India watching and labeling videos" (or functional equivalent)?
