Some of these practices might be based on wrong assumptions and I'm not aware of it, so I would appreciate any feedback.

1. avoiding some dependency conflicts:

   • install sbt-explicit-dependencies globally in your ~/.sbt/{0.13,1.0}/plugins/plugins.sbt
   • run undeclaredCompileDependencies and make the obvious missing dependencies explicit by adding them to libraryDependencies of each sub-project
   • (optionally) run unusedCompileDependencies and remove some obvious unused libraries. This has false positives, so ; reload; Test/compile after each change and ultimately run all tests to see that it didn't break anything
   • (optionally) add undeclaredCompileDependenciesTest to the CI pipeline, so that it will fail if you have some undeclared dependencies

2. keeping dependencies up to date and resolving conflicts:

   • install sbt-updates globally in your `~/.sbt/{0.13,1.0}/plugins/plugins.

Add the following library:

libraryDependencies += "org.bouncycastle" % "bcprov-jdk16" % "1.46"

I’m looking forward to the Sass Fundamentals workshop! A few notes to ensure you’re set up in advance are below.

See you soon!

Node.js

You’ll need a relatively recent version (v4.5 or newer, v7 ideally) of node.js installed. On OS X, a great way of doing this without disturbing your existing dev environment is to install NVM. Installation instructions are here.

A list of languages which compile to JS (Elm, Purescript, OCaml)
(Inspired by this thread: https://groups.google.com/forum/#!topic/elm-discuss/Um7WIBTq9xU)
They all support curry calling convention by default.

Some interesting results:

1. `min` is curried function, only OCaml(BuckleScript) managed to optimize this overhead.
2. All optimize the self tail call
3. Only BuckleScript and PureScript type-specialized comparison functoin (>=) and inlined

First step: Install Android SDK

1. yaourt -S android-sdk android-sdk-platform-tools android-sdk-build-tools
   Note: Maybe you'll have problems with the lasta package: ncurses5-compat-libs. In order to avoid this problem you have to use this command: gpg --recv-keys F7E48EDB. You can find clarification here.
2. yaourt -S genymotion
   Note: You'll need install virtual-box and his modules, yaourt will make for you but you need choos between ArchLinux host modules or DKMS host modules.
3. Enter in super user mode with su - and then do echo -e "vboxdrv\nvboxnetflt\nvboxnetadp\nvboxpci" > /etc/modules-load.d/virtualbox.conf
   Note: You need do this with super user because need super user permissions and with sudo, for us at least, doesn't work.
4. sudo modprobe vboxdrv vboxnetadp vboxnetflt
   Activate for current session.
5. sudo chmod -R 777 /opt/android-sdk

Directory structure for JavaScript/Node Projects

While the following structure is not an absolute requirement or enforced by the tools, it is a recommendation based on what the JavaScript and in particular Node community at large have been following by convention.

Beyond a suggested structure, no tooling recommendations, or sub-module structure is outlined here.

Directories

• lib/ is intended for code that can run as-is
• src/ is intended for code that needs to be manipulated before it can be used

Virtualenv

It is always recommened to use virtualenv while you are doing development. virtualenv lets you create isolated development environments. It will help you not to mixup dependencies when working on more than one project on your machine.
