Fun with Gas – What happens with your voice if you inhale a gas lighter or denser than air?

In this video from MythBusters, you can see what happens if you inhale a gas lighter than air (in this case Helium) or if, on the other hand, you inhale a gas denser than air (in this case Sulfur Hexafluoride). In the first case, your voice turns into a chipmunk’s and in the other one into Satan’s!

Very funny and interesting :)

Thanks Fepe!

Joke: Mirror Without Reflection (Two twins in a public bathroom separated by a glass)

This is an excellent video I received almost an year ago (thanks Fepe!).

It is a joke made in a public bathroom in which the mirror had been removed and replaced by a transparent glass. A woman pretends to be making herself up (in front of the fake mirror) while her twin sister is on the opposite side of the glass looking like it was her reflection :).

It’s very funny to watch the reaction of the different people that get into the bathroom! :)

Enjoy it!

Move Facebook Events Box to Top updated to version 1.2.1


It has happened almost no time since the last update (I made it yesterday), but I had to make a new release to correct one remaining problem which made the script not to work sometimes with the new site structure (specifically when returning to home without reloading after some kind of actions, for example, clicking the “Return to home” link after cleaning up all the pending requests).

You may have not seen the problem, but anyway I recommend the update because Facebook keeps changing the site structure and this is the best working release (its been doing its work flawlessly in every case I’ve tested it in by now).

Please visit the original post to download the updated version.

Move Facebook Events Box to Top updated to version 1.2


Since some days ago, the Move Facebook Events Box to Top script has stoppped working in some Facebook accounts (while it kept working in some others).

It happened to be that Facebook is updating some parts of its page structure and that changes generated the problems.

I’ve just updated it to the version 1.2 to solve the problem .

Updated: qTranslate support for the Google (XML) Sitemaps Generator WordPress Plugin 3.1.6 (2nd Release)


Although, as I said in the original post, I had not originally written the code modifications to enable the qTranslate support for the Google (XML) Sitemaps Generator WordPress Plugin, I decided to make some corrections myself to do the following things:

  • Home page now appears in the different languages in the sitemap.
  • Entries not written in the default language do not appear anymore in the sitemap. Now, just the written languages appear. (Thanks Blutarsky for notifying the bug)

The updated code modifications and the new download version are in the original post:

How to fix the “You do not have sufficient permissions to access this page” message in WordPress

I’ll tell you my story, but you may be in the same situation having done something completely different, so keep reading…

One day, some time ago, I was very happily installing the WP-Security-Scan WordPress plugin, and I got an analysis result saying that I should change the default WordPress database table prefix in order to make harder the potential SQL Injection attacks…

Firefox Add-on: List Open URLs

Let’s say you’re searching for videos (or webpages if you wish) of some topic. And you navigate through lots and lots of them… Opening new tabs and even jumping between links without leaving the previous URL open somewhere else (this commonly happens when you click any “Related Video” on YouTube, since it automatically opens on the same tab)…

It would be really tedious to go through each of your tabs rescuing all the interesting URLs to save them…

Also, if you could save them as bookmarks (assuming you don’t care about the browsing history), it’s not really simple to just get the URLs to copy them or to send them to somebody else…

For this (and for any other case you could find), I developed the “List Open URLs” Firefox Add-on…

Perpetuum Jazzile playing “Africa” (Toto’s song)

This time, I brought you a music video a friend of mine sent me by e-mail… But it’s not any music video… It’s a cover of Toto’s “Africa” song, but made in a very special way…

Its performed by an incredible choir which can simulate a Thunderstorm using their voices and bodies…

A must see…
