Curious, can you forward that article? I had some trouble with lv in firefox and it would be nice to know if theres an easy fix

Yes you are totally right. As I was writing the script I realized it got complex and bushy very quickly. I think I will have to rewrite lately with some more appropriate scripting langage.
Sure, I just created a public git repository…
It is nothing very extraordinary and it may seem quite closely related to my own needs.
So let’s say I have a new project my_umbrella with 2 Phoenix apps: admin, front.
First I execute this bash script.
me@pc:~/Forge$ ./umbrella_releaser /path/to/my_umbrella/
This will generates .forge folder inside the project and add a directive into the project .gitignore file to not track it.
Here is the tree of that folder:
├── build
│ ├── compiler
│ ├── phx
│ │ ├── admin
│ │ └── front
│ ├── releaser
│ └── supervisor
└── env
└── release.env
When I want to build a new release I run .forge/build/supervisor:
- that will source the
env/release.env(export all necessary production secrets) - run the
build/compilerscript (update/install the whole project dependencies) - run each
build/phx/app_name(install and compile Phoenix assets) - run finally
build/releaserto build the actual release.
There are some requirements for that scripts to work but we can easily removes some lines to bypass that. This is essentially the lines I run audacious music player as background process. That is why there is a bgm folder in the repository root. Audacious will search for music in that folder and start playing them during the whole process. When the music stops I know that the script has done its job. ^^ For the Audacious to play the music we need also to add some music files into the bgm folder of course.

I certainly can! It’s this https://medium.com/@benhansen/lets-build-a-slack-clone-with-elixir-phoenix-and-react-part-7-deploy-to-heroku-6b3d1ce9bfd5
The part that helped me fix the issue is the configuration for the prod.ex toward the top.

Redoing a blackjack simulator I wrote in Ruby in 2015 (conclusion: don’t play blackjack unless you can count cards without getting beaten up by the casino) using Elixir.
Just getting started … got some card deck code from
https://github.com/seven1m/30-days-of-elixir/blob/master/13-card-deck.exs
And have ‘player’ and ‘hand’ and ‘card’ and ‘handvalue’ code kind of working … but wondering about the best way to handle persistent data: the deck(s) getting smaller as cards are dealt out.
So far I’ve seen:
- Tuples aren’t really immutable
- OTP and GenServer
- Ecto
Any suggestions for the best approach?
Thanks much!

Tuples are immutable, I would use GenServer with list. Using DB would be enormous overkill.

I suggest reading through @sasajuric’s to spawn or not to spawn it uses a blackjack game as the running example, showing how to model the game functionally and introduce processes to host a multiplayer server.

I actually figured it out; I’m using an Agent to handle the state of the “discard pile”. This was just a few extra lines of code and seems to be working fine.

I am just curious, what is the reasoning behind the idea that “tuples aren’t really immutable”?
mcwiggins
No reasoning; just a (quite possibly erroneous) statement I saw somewhere when doing research on my problem.

Using Elixir to test some ideas for secured file transfers servers.
Then now learning Phoenix/LiveView to test some others ideas to build a Web gateway to monitor these servers, minimizing database use and maximizing real time exchanges between the servers and the gateway by using Phoenix channels.
