new website

I’m switching from WordPress to a virtual private server. I’m playing with a VPS. So far, I’m happy with their domain registration service. Also, they offer some discounts for Debian people. Btw, I still have a promo code for a one month free VPS share which I’m allowed to give away.

For my new website (same old URL) I’m using PyBlosxom over Lighttpd in a Debian GNU/Linux system. I want to keep things simple by git-pushing plain text files for all html content.

For the blog system I’ve just written a plugin which gives PyBlosxom the (very nice!) txt2tags formatter (source: There’re still issues to fix but it’s working quite well.

So, thanks WordPress for all the fish. This is probably my last post here. (although I’m keeping the current account active for comments)

São Paulo police treat street artists like criminals

This guy is very known by people who use to walk around the Paulista Avenue at night. This week Gilberto Kassab – mayor of São Paulo – authorized the local police to arrest him and all other artists in order to replace them by one more crap christmas tree playing those well known depressed songs. SAD :_(

Pidgin / Finch users x Microsoft certificate error

I still have some social life with non-geek friends who keep using MSN for instant messaging. I’m currently using Finch, which is a libpurple-based IM. If you’re in a similar situation, so you probably came to this post due to a certificate error message from Microsoft servers when trying to start your Finch (or Pidgin).

All you need is download the following updated certificates from Pidgin website and replace them into your purple installation dir (probably in /usr/share/purple/ca-certs):


It’s finally done. For several reasons I moved all my domains from GoDaddy to

If you are not convinced, so try this. At least you’ll understand the real meaning of brainless marketing.

Government Resquest tool fails

So it’s no surprise that Google, like other technology and telecommunications companies, regularly receives demands from government agencies to remove content from our services. Of course many of these requests are entirely legitimate, such as requests for the removal of child pornography (1). We also regularly receive requests from law enforcement agencies to hand over private user data. Again, the vast majority of these requests are valid and the information needed is for legitimate criminal investigations. However, data about these activities historically has not been broadly available. We believe that greater transparency will lead to less censorship (2).



Do your statistics cover all categories of content removals?

No. Our policies and systems are set up to identify and remove child pornography whenever we become aware of it, regardless of whether that request comes from the government. As a result, it’s difficult to accurately track which of those removals were requested by governments, and we haven’t included those statistics here.

(So, why did you mention this as “these requests”?)


* Chinese officials consider censorship demands as state secrets, so we cannot disclose that information at this time.

(where’s the real transparency?)

Furthermore, I tell you the incorrectness regarding requests/removals data from Brazil in your tool is a big truth.

This is supposed to work…

It’s only about business.

That’s what you get…

…if you park your motocycle in a forbidden zone for a few minutes to have a sandwich in São Paulo. Of course it wouldn’t happen to any white/rich person.

Despite the clear images, all those police men stated they didn’t attack the motoboy. I don’t know if term “motoboy” is used in english, but here in Brazil it means a guy who uses a motocycle to make some money (about $3/hour) delivering things. Bad.

Who needs a wifi switch?

Wifi stop working. Thinkpad x60. Debian GNU/Linux. Intel(R) PRO/Wireless 3945ABG/BG. Logs below:

…about 1 hour trying to solve that annoying issue, and then I realize there was a f** wifi switch turned off right in front of my face. #FAIL

Single tree-like navigation topbar for Beamer

I like the Antibes and JuanLesPins themes from the Beamer class. They use a nice tree-like navigation at the top, which provides a good notion about where exactly the speaker is in her/his talk. This feature is especially important for presentations given in places where attendees don´t care too much about being in time.

Antibes and JuanLesPins use the tree and smoothtree “outer” themes. The problem for me is that they provide a 3-level tree navigation (Title, Section and Subsection), plus the Frame Title. I don´t have subsections in my presentations. Also, I don´t think it´s necessary to have the main title in every single frame (but if you enjoy it, try using one of the nice beamer footer instead, for example the one from Madri theme).

Unfortunately I couldn´t find any beamer theme with Section plus Frame Title only. So, a very simple cleanup in the tree outertheme gave me what I was looking for:


If you want to use this, just set it as the outertheme in your tex. Supposing the file name is beamerouterthemesingletree.sty and it´s located in the same directory as your tex file, add:


Vibration Reduction matters

I’ve just bought the cheap Nikkor 18-55mm VR lens for my Nikon D50. According to, this lens does the job very well. Actually I was looking for the amazing 18-200mm VR, but noted it’s too expensive for me. At least here in Brazil it costs 5x more than that 18-55mm.

The question is: once I already own a basic Nikkor 18-55mm which came with the camera, is that worth upgrading to another 18-55mm only because of this Vibration Reduction feature? Well… I was not sure really about that. I just trusted Ken Rockwell’s opinion and decided to give it a try. So, checking the result below you may guess whether I’m happy or not 🙂

These pictures were taken in f11, 55mm, 1/4 sec, no post-edition. I did my best to get them as much sharpness as possible. For a 100 shots sampling from Ken Rockwell look for the “Vibration Reduction at 55mm” table here.
