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 to look.

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 cases it’s usually best to sit back and listen a bit..

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 with my own children, I’ve seen again and again that you ca

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 author feels confident in this theory, I suggest they

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 content are still not a (widespread) thing. Consumers ha

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 if we truly get there–who knows? If you beli

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 mental model of how we operate (which is how the open

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. Of course, other kinds of life are p

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 gradually typed language" prior t

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 practice, you may get better performance from

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, 2}, owner: #PID<0.954.0>, pid: #PID<0.9

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 caller process will exit. If the task process is linke

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 never terminates: iex> f = fn i, f -> if re

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/nutritiontodayonline/abstract/2019&

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) need to be taken with a grain of salt, including: - health

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 aren't clear or well-established patterns for ho

This kind of unicellular complexity & intelligence has long been my soapbox material in the AGI debate. Even long before the current LLM craze, people were counting neurons in the brain and making bold claims about machine intelligence

It's a special kind of person who cares enough about math to celebrate "pi day", but not enough to be disturbed by the approximation of 3.14.

Another qualifier: "viable". Every viable single-point mutation. This may seem obvious and covered by the "could exist", but it does mean that for any given base pair you won't necessarily find somebody in the pop

What's funny about this (legit) criticism is that non-AI HR people have been doing this for years.

I think there's another, more frightening takeaway from this - people are losing trust in everything. While you can argue on a case by case basis that it's all for good reason, it pretty much devolves into nihilism. More and mor
