Beam/OTP has a lot of tools for understanding the runtime state of the system. And you can attach the REPL to an existing, already running instance. As with many things Elixir/Erlang related, there isn't a lot that's uni

Note that ROV stands for Remotely Operated Vehicle - it is not autonomous, it is controlled by a person. What you are describing would be called a UUV (unmanned underwater vehicle) or AUV (autonomous underwater vehicle).

I'd like to clarify a little what the OTP is vs the BEAM - this article does an OK job at that explanation but confuses it a little. The BEAM is the underlying VM used by Erlang, Elixir and Gleam. The BEAM provides the basic primitives

Terminals and shells aren't like window managers where you can just subdivide your drawing space and pass a block pixels to something else to draw on. What the terminal processes processing is a stream of bytes from the shell and needs

I would argue that connected devices should only rely on your services - otherwise how do you know that they're not going away? And if they're your services then you can maintain their stability.

Some years ago I did a production of Gilbert and Sullivan (I think Ruddigore - I've done a few). We had a talent night, and one of the guys did "The Elements" at full tempo while also solving a Rubiks cube and had it done bef

Teams on the desktop has improved with their "v2" client. It's not the world's fastest piece of software, but I find it to not be embarrassingly slow now (on a reasonably specced machine). One as to hope that the same pe

Any connected device NEEDS continual updates in order to continue to be secure. This is particularly true of internet connected devices, but is also true for IOT devices that only connect to the internet indirectly. Security holes get found

This largely feels like a failure of consumer protection. Perhaps my understanding of the legal situation is wrong but as a UK resident - regardless of additional warranties provided or not provided by the vendor - products should work for

> Using C-like structs is a very common use case Not true. Using C structs themselves in C++ is very common - when you include the C header file, the relevant declarations are wrapped in "extern "C" {}" which gives s

I'd rather redirect my momentum into soft webbing spread across my lap, than into my head impacting an overhead bin.

Your point is well made, and this is an unfortunate consequence of the regulation (and I enjoyed the analogy). But it isn't necessary to have cookie banners on every website. Github is a moderately complex, user-optimised website, righ

Elixir and its Task module ( https://hexdocs.pm/elixir/1.12/Task.html ) is the best of both worlds here. The fundamental concurrency system is green threads (similar to Go), which makes for a fantastic programming m

The more important number for a codebase that size is almost always "what's the incremental build time for whatever I work on". It's nice to have a "build from scratch" be fast, but almost always you can leav

Having music in a car isn't safety-critical. But we should have unflinching acceptance of reality that a lot of people WILL have music in the car, and so if music adjustments are unsafe then the car is more unsafe. A while ago I worked

Yeah, even on HN that's not an acryonym you should use without explaining. My first thought for RAG is "Red, Amber, Green" as used on risks etc. with project management.

I have found 8GB RAM to be completely unusable on Windows and Linux these days. Once you've got Chrome open with half a dozen tabs and any even slightly memory hungry program (VS Code or Android Studio etc.) you're out of luck. Ac

Thank you for answering. For me "not needing to pull before pushing" is nice, but not game changing (but helpful to understand nonetheless). It's more the cases that you allude to that we instinctively avoid in git!
