Twitter and pidgin

Today I decided to give Twitter a chance. Started to see, try to find out how to use it, and then I suddenly felt that all that I wanted to blog, the short things, I could do with Twitter. Short jokes, comics, interesting links, stuff like that.

After that discover, I went on the journey of trying to use it from inside an IM, since I don’t want to access twitter.com every time I feel to twitt(er) something.

The steps for it are:

  1. Go to your preferences in twitter and enable the “Device Updates”. Then setup the IM user to which you want the updates to be sent;
  2. Add the user twitter@twitter.com to your IM account, as a buddy. In my case, a gtalk account.

I started to test it, and then the first issue came, that Otubo pointed me: twitter limits the posts up to 140 chars. How can I see that in pidgin?

So, thinking that someone (hopefully) had already thought about it, and relying on google, I found a plugin for pidgin that adds the number of typed chars on a chat window. Here it is, and it’s called pidgin-convcharcount-plugin. There you can get the patch, the source or the compiled libs as packages.

As I am using ubuntu right now, I’ve just installed the deb package available (found it on apt, later). To my friends, gentoo users (as otubo), sorry folks, but I didn’t find the package in the portage tree. :(

So, you’ll have to do it in a harder way. You can pick up the package source (tar.gz) on the site, untar it and perform make. It has a script (Makefile) that downloads pidgin source, patches it, and compiles the plugin libs.

I mean, this is the easiest way, but you can pick the patch instead, download pidgin source by yourself, patch it and yada yada. :)

After that, the libs should be placed on /usr/src/pidgin folder. It worked like a charm in here.. :)

Hope this helps. Any issues, let me know. :)

Finding and removing empty folders

Imagine that you decided to download a torrent that originally has a million folders. Then, imagine that you’ll only download actually one or two of them. Imagined that?

Now, imagine that you’re cleaning your files, you know, and then suddenly you see yourself in front of that million of empty folders. Of course you want to rip them off!

Knowing that find is a **VERY** powerful tool, reading its man I found out the following:

$ find . -type d -empty

And voila, only the empty dirs of the folder you are are returned.

Now, to delete them you have two options:

$ find . -type d -empty -exec rmdir "{}" ";"

(This should execute rmdir n times, where n is the number of empty folders the find command returns.)

or

$ find . -type d -empty | xargs rmdir -

(This should get all the output of the find command and use as input to rmdir command, wrapped by xargs.)

Both of them should work.
