After a while without touching the blog (I had good reasons), has returned the activities …

Searching for cool python related plugins for VIM I found (tripped) in a theme called Wombat, a variation of Desert theme created by Lars H. Nielsen. So, I get it, and worked a bit on, making some changes to made it a bit more dark, like I did on my custom desert theme.

Here is a 1440×900 screenshot with two gvim opened with original wombat and my modified wombat theme:

original wombat theme with my custom wombat theme

With more vivid colors I think that is better to read on night, with no light (how I normally code when my room colleague sleep). This week I code a lot on my timetracker project (soon I post something about here) and my girlfriend’s blog, and talk how this theme looks for coding.

Enjoy!

Hello my dear readers (I hove that already exist someone :])

Today I decided to put some optimizations in Wordpress, and I’m really impressed! The big optimization are adition of WP-Super-Cache plugin. After actived I get a load diference from 10 seconds to 3 seconds using Mozilla Firefox on Linux. Really a big optimization.

Also, I actived follow plugins:

• FeedBurner: stats for my feeds, tracking, etc.
• Google Analytics: stats for my site access.
• StatsPress Reloaded: stats for my site access in real time.

With these plugins my plans are follow blog evolution and access.

Let’s see results in some days.

Hey people

After a long time without post on blog, but always colecting ideas, the tip of today touch in a delicated area, code indent. Around all word we found ugly and mall indented codes (except in python :]), and, when working with PHP, this is a case extremely normal and really sucks.

So, one day, I start to search for a batch mode for vim, because for me, reident of PHP files with vim is awesome!. My idea is a single script that launchy vim in batch mode for each file, reindent and save.

Very well, after about 30 minutes of talk in #vim da irc.freenode.net, some people talk about ‘-c’ option, that, for some reason, I not see on vim man pages :\. Now let’s tip!

Bem, certo dia da minha vida, tive que kickar um sysadmin do servidor dele, onde eu
estava instalando um portal pq ele realmente estava me atrapalhando, ficava reiniciando postgresql toda hora, o servidor também … enfim, ridículo .

Me bateu uma luz (por causa do mesmo sysadmin) hoje e fiz uma coisa legal, segue
abaixo um script para kickar todos os usuários que não seja o que vc passar ou
kickar o que vc passar, pegando principalmente por IP/Maquina deles.

Naturalmente você só poderá rodar o script como root, mas acredite, não é difícil conseguir.
A maioria dos servidores acaba dando uma permissão com sudo a algum arquivo usando vim, tipo, sudo vim /etc/apache/vhosts/seuvhost.conf, dentro do vim, execute :!su - e você terá um shell como root.

Install this script in one server that can send ICMP requests to servers in lists. Very old versions of postfix doesn’t works because this script needs -a option in mail command. Use as:

./script

Run in cron and have peace
