This article makes a logical step that I think is incorrect - that message order from the server is the order that a client then displays them in. Surely that's a presentation issue - you should display messages chronologically, regard

Don't worry - this is an accurate and concise summary of what Nerves is. What I would add is: you do not have bash (or sh, or any other "conventional" shell). The BEAM is your userspace. You can SSH in, but what you end up

Isn't the "cimport" stuff in Zig going away at some point? Making this somewhat less useful.

One suggestion for local branch logging - you can do `git log master..` and it will show you the log of commits on your branch, stopping when it gets to (the common ancestor with) master. I don't use many aliases, but I do use that com

I would love to hear any suggestions for how to remove all my stored passwords in Firefox. I used to use Firefox password manager but moved to Bitwarden. It has been surprisingly difficult to remove passwords completely as I'm using Fi

I very quickly had no sympathy at all with the museum. It obtained funding to do the scans with the express purpose of providing to the public, and then decided not to.

I do agree on not letting nuclear reactors explode, but I did use the SpaceX example on purpose. Before SpaceX started to do it, the concept of iterating to that degree on rockets was unthinkable. There was a self reinforcing loop of "

I firmly believe that iteration is the key to good engineering. SpaceX has got where they are (partly) due to running flight after flight with incremental improvements each time. The problem with the massive reactors is that you get to buil

Yes, I've just discovered that in parallel. All I need for perfection is to be able to enable/disable that in the view dynamically (and the cursor stay in the same place). But what's there is actually useful and I've ins

All I want is a good TUI git log viewer. I'm perfectly happy to do all the operations on the command line, but navigating the log works well interactively (e.g. start as --first-parent, with single line entries and then be able to se

I'd love to point you at some code from work but it's all closed source unfortunately. One example that gets used is https://github.com/hexpm/hex which is the code behind the Elixir package management website

It's a functional language with all the usual bits that entails, so writing pure code is right in its wheelhouse. It's a pragmatic, dynamic language, so very much an easy on-ramp to functional programming. The testing library (ExU

Indeed - that is the exact architecture that the book is talking you through. It maps it well on to the specific tools you have available in Elixir. Unsurprisingly, Elixir is an extremely good fit for this architecture.

It's not just codecs that are different between HFP and A2DP (although that is a big part of the issue). HFP uses an older way (SCO) of transferring the audio which gives much less bandwidth. What we need is a new profile that uses A2D

There are two bluetooth profiles in use here: "A2DP" (Advanced Audio Distribution Profile) and "HFP" (Hands Free Profile). A2DP is how you send high quality audio over standard Bluetooth. The basic codec is OK, and you c

Once you are familiar with either Erlang or Elixir I strongly recommend the book "Designing Elixir Systems with OTP" (the one with the bee and honeycomb on the front). It's not a programming tutorial, but it shows how to st

True, that's definitely possible. I was giving the habitual answer (that I occasionally need to explain to a client at work) why you need to spend $2m having an ASIC made when "it's just digital logic and we got the prototype

The power profile of an FPGA is very different (worse) than dedicated silicon. Both the background current and cost of a gate switch. There are a lot of situations where that isn't acceptable.

Worth noting that major languages seem to be moving away from this model. Rust and C# both concluded that the needs of your actual compiler are very different than the needs of an incremental tool that can run on partially written code.

The key superpower is a culture of refactoring when needed. I firmly believe you should design for the problem you've got now, and not worry too much about the future. You're usually wrong about it anyway! This is fine, as long as

We expect people to have a labbook per project. They are logged when handed out, and signed back in at the end of the project. For a science/engineering firm, this sort of arrangement isn't uncommon, because stuff you do in the la
