To run this, you can try:

curl -ks https://gist.github.com/nicerobot/2697848/raw/uninstall-node.sh | bash

I haven't tested this script doing it this way but i run a lot of my Gists like this so maybe this one'll work too.

Alternatively,

curl -ksO https://gist.github.com/nicerobot/2697848/raw/uninstall-node.sh

bash ./uninstall-node.sh

#For jpeg files
#Need to install jpegtran in ubuntu
sudo apt-get install libjpeg-progs

Usage tips:
#To optimise a single jpeg image:
    jpegtran -copy none -optimise -outfile image.jpg image.jpg
    
#To optimise all jpegs in the current directory:
    for img in `ls *.jpg`; do jpegtran -copy none -optimise -outfile $img $img; done

VP8 vs H.264 - Which One is Better?

So I was reading Hacker News and decided to read the comments in the thread about H.265 being approved. Pretty close to the top was this comment about VP9, Google's future video format. I have some words of my own about it and other future formats at the bottom of this post, but what jumped out from the comment to me was this part:

Many have already implemented VP8 (which is also slightly better than h.264 at this point)

The comparison linked to back up that statement is faulty for several reasons, such as not providing the source material used (hell, he doesn't even name the source material), exact encoding settings used (no, some random profiles are not enough), not providing the resulting encodes, only providing a

The new Secure Password Hashing API in PHP 5.5

The [RFC for a new simple to use password hashing API][rfc] has just been accepted for PHP 5.5. As the RFC itself is rather technical and most of the sample codes are something you should not use, I want to give a very quick overview of the new API:

Why do we need a new API?

Everybody knows that you should be hashing their passwords using bcrypt, but still a surprising number of developers uses insecure md5 or sha1 hashes (just look at the recent password leaks). One of the reasons for this is that the crypt() API is ridiculously hard to use and very prone to programming mistakes.

###Nginx config to make Chef servers WebGUI (localhost:4040) and 
###REST API (localhost:4000) both available over SSL in the same vhost.
#If your SSL certificate requires a CA Cert bundle, then you may also need to install/symlink a copy of the

#need to access these SSL endpoints. 
# This is typically needed for RapidSSL/Geotrust issued SSL certificates, YMMV.
