How do I make existing non-bare repository bare?

Giovanni Cappellotto — Thu, 27 May 2010 07:48:32 +0000

I started a git local repository, but how can I make this existing repository a bare repository?

ssh to remote server
git clone --bare -l
renamed old repository directory
renamed new repository dir to what old repository used to be

Mp3 to png source code

Giovanni Cappellotto — Sat, 17 Apr 2010 21:57:48 +0000

In a previous article I talked about a little rails project to convert mp3 audio files to their graphical representation (waveform) in png format. After few comments asking me to release the source code here it is, but before this I must thank rjp’s cdcover project from where I took some of the code showed here.

If you plan to use this code as it is or in a modified version please let me know so maybe we can contribute to improve the code or just to keep in touch!

Notes

the code is written in ruby programming language (great!), you can run it from command line with few modifications or use it as a library in your rails projects
to run this code you must install some dependent gems: RMagick (which also depends on ImageMagick libraries) and NArray
to enable the conversion from mp3 audio encoding to raw audio format you must install SoX a command line utility described as “the Swiss Army knife of sound processing programs”
I’ve embedded some content from sox man pages near the command execution to better explain how sox works

You’ll find all useful links at the bottom of this page.

If you find this code useful please donate!

Select all Facebook friends

This little script helps you to select all your facebook friends (to share something or send page suggestions):

Using Firefox and Firebug open a facebook page, click “Suggest to friends”, a popup window with all your contacts will open.
Paste inside the console area the code above than click “run”, all your friends should be now selected!

Update:
There’s an easiest way to run this code, just put it all in a row and prepend the keyword javascript: than paste the object code inside the address input field of the browser and press enter.

Copy and paste inside address bar:

Talking about a new web project with Nicholas:

me: “Can i have access to project source files?”
Nicholas: “No we’ll give you two magnets to tweak the harddisk… (big laught)”
