Requirements

• no upfront installation/agents on remote/slave machines - ssh should be enough
• application components should use third-party software, e.g. HDFS, Spark's cluster, deployed separately
• configuration templating
• environment requires/asserts, i.e. we need a JVM in a given version before doing deployment
• deployment process run from Jenkins

Solution

Vec3 Magnitude

These C# implementations of approximate magnitude with no square roots are actually slower than calling a native implementation in Unity, but if this were implemented intelligently in C there's a good chance they would be faster. In any case, they're here because it was a pain to get the magic numbers.

Accurate to within 4.5%.

public static float MagnitudeFast (this Vector2 self)
    {

If you want to use curl or net-http/open-uri to access https resources, you will often (always?) get an error, because they don't have the large number of root certificates installed that web browsers have.

You can manually install the root certs, but first you have to get them from somewhere. This article gives a nice description of how to do that. The source of the cert files it points to is hosted by the curl project, who kindly provide it in the .pem format.

problem: Sadly, ironically, and comically, it's not possible to access that file via https! Luckily, the awesome curl project does provide us with the script that they use to produce the file, so we can do it securely ourselves. Here's how.

1. git clone https://github.com/bagder/curl.git
2. cd curl/lib
3. edit mk-ca-bundle.pl and change:
