Don't use VPN services.

No, seriously, don't. You're probably reading this because you've asked what VPN service to use, and this is the answer.

Note: The content in this post does not apply to using VPN for their intended purpose; that is, as a virtual private (internal) network. It only applies to using it as a glorified proxy, which is what every third-party "VPN provider" does.

There's also this article about VPN services, which is honestly better written (and has more cat pictures!) than my article.

JS Dev quiz.

Most of these questions have several possible answers and no real wrong answer. The aim of the quiz is to gauge your level of experience with software development in general but also your experience working directly in Javascript, so add as much detail as possible, explain how you arrived at your answer, etc.

Some of the questions are quite difficult or confusing, so don't worry too much if you're not sure about the answers; a couple of them are deliberately designed to be hard to solve!

General questions

Describe the stack for a recent project that you found interesting.

Essential JavaScript Links

I no longer mantain this list. There are lots of other very comprehensive JavaScript link lists out there. Please see those, instead (Google "awesome JavaScript" for a start).

The introduction to Reactive Programming you've been missing

If you prefer to watch video tutorials with live-coding, then check out this series I recorded with the same contents as in this article: Egghead.io - Introduction to Reactive Programming.

a simple git branching model

This is a very simple git workflow. It (and variants) is in use by many people. I settled on it after using it very effectively at Athena. GitHub does something similar; Zach Holman mentioned it in this talk.
