The new JIT does improve the computational story a little, but yes it's a little like Python where you use it for orchestration and then offload the work. That said new systems like NX do make the 'offloading' part significan

Note that Erlang OTP 24 (the latest release) includes a JIT for the first time. It only runs on x64 but should significantly improve performance on that platform. For some workloads people are reporting as much as a 40% improvement. I would

This comment has made me realise that one of the key ideas of the Erlang runtime (over other concurrency implementations) is the link. For those of you not familiar with it, rather than just starting a process independently, you can start a

I have never needed to do that sort of memorisation in the past but have done recently. When I was a student my memory was good enough that I could skate through based on what I remembered from lessons/lectures/basic revision. In

I find it interesting that the language that best deals with parallelism (IMO) was invented significantly before we moved in the multi-core direction. The programming language landscape evolved and developed in the face of multi-code - asyn

Normal HTTP request latency is much better in Phoenix that in Rails. You can't do much about the intervening network latency but I'd expect a LiveView app to be snappier. Good practice seems to be the PETAL stack ( https:/&#x

Realistically, if you test with the camera apps from Apple, Google and Samsung I suspect you have 90% of the public's usage covered and everyone else will be forced to follow.

These are all problems that exist already and are just highlighted by pay transparency. I agree that they're difficult problems, but they're important ones. You definitely can't do a proper employee evaluation by a completely

The model skips an important part of the reasoning - some people might deserve to be paid more because they're more valuable (due to being more productive or whatever the equivalent is in a given industry). Pay transparency means tha

It's slightly more complicated than that because what they'll do is keep the properties and rent them. There being few houses to buy increases the demand for rent, and cornering the rental market means you can control rent prices.

I use nix-shell for dev environments. Once I've got it working it's wonderful - full replicable, across multiple development machines and CI. It's painful though. Some problems I've encountered recently on different pr

It is great, but a bit painful to learn and get working for you. I like to use Nix to provide my development environments but that's often painful due to conflicts between the Nix approach and how the language package manager wants to

OSX is a different abstraction layer from processor architecture. Until recently Mac hardware was x86 and all the deployment targets were x86. A VM could take care of all the other differences.
