Configure Git to use a proxy

In Brief

You may need to configure a proxy server if you're having trouble cloning or fetching from a remote repository or getting an error like unable to access '...' Couldn't resolve host '...'.

Consider something like:

timstclair

package scratch

import (
	"reflect"
	"testing"
)

A Quick and Dirty Lens primer

Why does Lens exist? Well, Haskell records suck, for a number of reasons. I will enumerate them using this sample record.

data User = User { login    :: Text
                 , password :: ByteString
                 , email    :: Text
                 , created  :: UTCTime
 }

 Remuxing

Why Remux Blu-rays?
-You use MPC-HC (or similar DShow players) and standard filters for playback. You can also use better quality renderers like Haali, EVR and madVR.
-You get the ease of playback of a re-encode without the quality loss. A double click off the .mkv will start the movie - no annoying warnings, loading screens, previews and setup menus.
-You don't have to deal with horribly bloated, unstable and expensive PowerDVD or Arcsoft playback software.
-You don't have to mess with ISO creation, correct BD folder structure, UDF and SPTD drivers, and image mounting every time you want to watch a movie.
-You never have to worry about the region code setting of a disc.
-You never have to worry about HDCP or PAP content protection.
-You never have to worry about your software player downsampling your audio - get full bit-depth and frequency resolution, 24bit/96kHz or higher, not 16/48.
