F1. FS 128k streaming writes

Benchmark: fio write

Command: fio --name=seqwrite --rw=write --bs=128k --size=4g --end_fsync=1 --loops=4 # aggrb tput

Rationale: Measure the performance of a single threaded streaming write of a reasonably large file. The aim is to measure how well the file system and platform can sustain a write workload, which will depend on how well it can group and dispatch writes. It's difficult to benchmark buffered file system writes in both a short duration and in a repeatable way, as performance greatly depends on if and when the pagecache begins to flush dirty data. As a workaround, an fsync() at the end of the benchmark is called to ensure that flushing will always occur, and the benchmark also repeats four times. While this provides a much more reliable measurement, it is somewhat worst-case (applications don't always fsync), providing closer to a minimum rate – rather than a maximum rate – that you should expect.

How-to setup a simple git push deployment

These are my notes basically. At first i created this gist just as a reminder for myself. But feel free to use this for your project as a starting point. If you have questions you can find me on twitter @thomasf https://twitter.com/thomasf This is how i used it on a Debian Wheezy testing (https://www.debian.org/releases/testing/)

On the server (example.com)

nternetinspired

// Requires jQuery of course.
$(document).ready(function() {
    $('.show-comments').on('click', function(){
          var disqus_shortname = 'YOUR-DISQUS-USERNAME'; // Replace this value with *your* username.

          // ajax request to load the disqus javascript
          $.ajax({
                  type: "GET",
                  url: "http://" + disqus_shortname + ".disqus.com/embed.js",
                  dataType: "script",
