Starting new fragments with Kotlin is easy

Example

val user = User(id = "id", name = "Ruby")
val userFragment: UserFragment = newFragment<User, UserFragment>(user)

How this magic works

swankjesse

fun main(args: Array<String>) {
  println("a" to "b")
  println("a" to "b" tre "c")
  println("a" to "b" tre "c" fo "d")
  println("a" to "b" tre "c" fo "d" fi "e")
  println("a" to "b" tre "c" fo "d" fi "e" sik "f")
  println("a" to "b" tre "c" fo "d" fi "e" sik "f" seva "g")
}

infix fun <A, B, C> Pair<A, B>.tre(c: C) = Triple(first, second, c)

Node.js TLS plain TLS sockets

This guide shows how to set up a bidirectional client/server authentication for plain TLS sockets.

Newer versions of openssl are stricter about certificate purposes. Use extensions accordingly.

Prepare certificates

Generate a Certificate Authority:

Here is a script to take the hosts from From http://pgl.yoyo.org/adservers/ and convert them to rules for Little Snitch.

It has options to grab the entire list or grab new entries past a certain date.

Just grab the output and copy/paste into Little Snitch.

The script is written to block access to any process, any port. You can also delete those lines and it will only block Mail. Or use the options to enter any process, port or protocol you want to block.

Code is clean if it can be understood easily – by everyone on the team. Clean code can be read and enhanced by a developer other than its original author. With understandability comes readability, changeability, extensibility and maintainability.

General rules

1. Follow standard conventions.
2. Keep it simple stupid. Simpler is always better. Reduce complexity as much as possible.
3. Boy scout rule. Leave the campground cleaner than you found it.
4. Always find root cause. Always look for the root cause of a problem.
