Letter to a Young Haskell Enthusiast, by Gershom Bazerman.

Condensed from: http://comonad.com/reader/2014/letter-to-a-young-haskell-enthusiast/

The following letter is about tendencies that come with the flush of excitement of learning any new thing. It is written specifically, because if we don't talk specifics, the generalities make no sense. It is a letter full of things I want to remember.

You’ve entered the world of strongly typed functional programming, and it is great. You want to share the great things you’ve learned, and you want to slay all the false statements in the world.

Compile dynamic template from outside of angular

I want to load dynamic HTML content via AJAX, then compile it, because it contains angular directives.

<!DOCTYPE html>
<html ng-app="app">
<head>

Channels Are Not Enough

Intro

Most VPN Services are Terrible

Short version: I strongly do not recommend using any of these providers. You are, of course, free to use whatever you like. My TL;DR advice: Roll your own and use Algo or Streisand. For messaging & voice, use Signal. For increased anonymity, use Tor for desktop (though recognize that doing so may actually put you at greater risk), and Onion Browser for mobile.

This mini-rant came on the heels of an interesting twitter discussion: https://twitter.com/kennwhite/status/591074055018582016

You got your hands on some data that was leaked from a social network and you want to help the poor people.

Luckily you know a government service to automatically block a list of credit cards.

The service is a little old school though and you have to upload a CSV file in the exact format. The upload fails if the CSV file contains invalid data.

The CSV files should have two columns, Name and Credit Card. Also, it must be named after the following pattern:

YYYYMMDD.csv.

-#!/bin/bash
-# apt-get install jq
-#set -eu
-shopt -s nullglob
-readonly base_dir=$1
-if [ -z "$base_dir" ] ; then
- echo 'please location docker registry store location!';
- exit;
-fi

-#!/bin/bash
-JQPATH=$(which jq)
-if [ "x$JQPATH" == "x" ]; then
-  echo "Couldn't find jq executable." 1>&2
-  exit 2
-fi
-set -eu
-shopt -s nullglob

	beforeEach(inject(function($rootScope, $compile, _$window_) {
