One thing I love about Elixir is I had read the Erlang book from Joe Armstrong ages back, and a lot of ideas and concepts still apply. I just didn't get into Phoenix cause PGSQL is a PITA on Windows, so I have to go back and try with MySQL instead.

Use Vagrant! Then you don't have to install/run PostgreSQL natively at all, and can run it inside a Linux VM.

My preferred way of learning a new language/framework is watching someone walk through creating a real app in that language/framework so I can see all the folders/files I need to touch and the thought process moving step-by-step. Unfortunately I haven't found much in the way of that for Phoenix, the stuff on Udemy is pretty outdated last time I checked. Any recommendations?

The way I've learned so far was building my own app while skimming the docs and looking at successful open source projects like https://github.com/thechangelog/changelog.com for inspiration and guidance. Basically error driven development and looking up things as needed. Of course also taking advantage of IRC / Slack / Forums when I get really stuck. But recently I read the Programming Phoenix 1.4 book (written by th…

Glowing recommendation, I'll have to check it out!

The thing is, nowadays, statically typed languages became so ergonomic, there is really no reason to go with dynamic languages.

That's exactly what I do at https://alchemist.camp . Most the videos and all the intro-level ones are free. I've also put up about a hundred screencasts at http://youtube.com/alchemistcamp .

Looks like a cool site. I'll check it out. My Elixir is Good. My Phoenix is not.

I’m building a side project in Phoenix right now. For me the learning curve is wondering whether Phoenix has a built-in or “everybody does it this way” solution to the problem I’m facing or whether it’s something I should implement myself.

In Rails the answer is always “use this popular gem” and in Go the answer is always “roll your own”. Phoenix is somewhere in the middle.

The cognitive load is quite low when deploying changes which only involve your app code (i.e., no dependency upgrades). My app has a few tens of millions of open websockets at a time, and it's worth it to me to avoid mass reconnects. I'm not everyone, but my use case isn't totally unique either.

I am not sure about your specific use case but it owuld be hard to imagine that graceful reconnect on websocket + a more traditional deploy would not be much more effective resourcing vs that hurdles you have to go through to properly appup. Is it really an advantage to you or has it slowed your ability to get to market for something that seems like it "should" be an advantage. Its not like you don't need graceful re…

It really depends on how much effort is involved in setting up the connections, and how much effort is involved in directing connections to a new host.

If I'm running 1M sessions per machine, and each machine can handle 10k new connections / second, rolling restart is really expensive. If I'm running 10k sessions per machine, and can handle 10k new connections / second, rolling restart isn't too bad. This generalizes to really anything that gather essentially ephemeral state, but that state is costly to gather (tcp flows in this case, data caches in others, etc).

BEAM excels at applications with huge numbers of sessions per machine, which is why some users really value hot reloading.

Editted to add -- the OTP application update sequence doesn't necessarily need to be used. Where I work, we certainly don't do that. Just a little bit of logic around code:soft_purge/1 and code:load_file/1

You could run PG in either WSL or a Docker container.

I currently use Windows (where I spend 99% of my time in WSL) and everything runs great.

What issues are you having getting Postgres setup in Windows?

I've used the Windows installer[1] and have had no issues.

Most people who point to Elixir's lack of static typing as a weakness, or believe their productivity would be adversely affected by it, do so because they haven't actually used the language.

Anyways, this subject occasionally comes up for discussion in the community. This post sums up my thoughts fairly well: https://elixirforum.com/t/static-vs-dynamic-typing/9824/3

I guess Elixir is "done" then? What could be the downsides to this?

Lack of language improvement. Sure, you can do anything with macros, but then when you open some random open source library it may be using different macros (or macros that are named the same way but act differently) than those that you use. Putting something in the language forces everybody to use the same standard. It can be good and it can be bad.
