Bionic Reader Bookmarklet

This bookmarklet is inspired by Bionic Reader API that is truly incredible. However I have issues with service APIs that are not clear on how they handle the privacy and security of my data. So I made a quick and dirty bookmarklet to do the job locally.

• Create a new bookmark in your browser
• Use this script as the address:

javascript:(function(){!function(){window.hasOwnProperty("bionicWordWrapApplied")||(!function(e){var n,t=document.createTreeWalker(e,NodeFilter.SHOW_TEXT,null,null);for(;n=t.nextNode();){for(var o,r=n.parentNode,d=n.nodeValue;o=d.match(/^(\s*)(\S+)/);){d=d.slice(o[0].length),r.insertBefore(document.createTextNode(o[1]),n);var a=Math.ceil(o[2].length/2),c=r.insertBefore(document.createElement("b"),n);c.appendChild(document.createTextNode(o[2].slice(0,a)));var i=r.insertBefore(document.createElement("span"),n);i.appendChild(document.createTextNode(o[2].slice(a)))}n.nodeValue=d}}(document.body),window.bionicWordWrapApplied=!0

Converting Audio into Different Formats / Sample Rates

Minimal example: transcode from MP3 to WMA:
ffmpeg -i input.mp3 output.wma

You can get the list of supported formats with:
ffmpeg -formats

Convert WAV to MP3, mix down to mono (use 1 audio channel), set bit rate to 64 kbps and sample rate to 22050 Hz:

Configure Synology NAS as Git Server

Instructions for setting up a git server on a Synology NAS with Diskstation. Specifically, I am using a DS414 with DSM 5.0.

Set Up User and Folder

• Create user gituser via Diskstation interface (with File Station and WebDAV privilages)
• Add new shared folder called git (located at /volume1/git) with read/write access for gituser and admin. This folder will hold all the repos.
• Install Git Server package via Diskstation

_Go to your Owncloud installation <https://myowncloud/remote.php/mozilla_sync> and accept the SSL Certificate
_Open about:config
_Create: services.sync.username <string> the value should be a hash not the username itself. (You only need the hash if the
sync was setup with a pre FF29, if you start from scratch the string doesn't matter)
You can look this up in an older browser or in the logs of your Owncloud server!!
_Go to: Preferences -> Sync -> Setup Firefox sync (you should see the old UI now)
  'I Have an Account'
  'I don't have the device with me'

  'Account' - again use the hash NOT the actual username!
