As announced yesterday on the YouTube blog, support for videos by tag <video> entered in tests.

What does this mean?

Means: Bye Flash and bye lag.

First, the <video> tag is already a standard of HTML5, without having to install additional plugins to view the videos (see below). Indeed, the flash only works right on Windows, who use Linux/Mac has to live with the flash consuming half the CPU to see a simple video. Who uses *BSD have to live with the emulation of flash for Linux.

But exists a problem. There is a discussion around <video> tag: "What codec to use?"

We currently have 2 codecs, in one side the free Ogg Theora supported by Firefox, Opera, Chrome and Chromium, on the other hand the proprietary H.264 supported by Chrome and Safari.

Google has chosen H.264, so now the videos can only be viewed in Chrome and Safari.

The new player is still in testing and very incomplete, with no possibility to use full-screen mode, can not display notes, advertisements and videos are converted to low quality. In videos that show advertisements the flash is used (for financial matters :P). Are also a few videos that are converted to the new format, you will have more luck if you try to watch new videos.

How to activate?

Just go to the activation page, enable and ready. Now you can go see the videos :)

See for example the trailer of Besouro(Brazilian Movie).

Well, being direct, Quassel is an excellent IRC client for KDE and I'm a user :)

It do all that others IRC clients do, like:

• Connect to multiple channels and servers.
• Colorations of nicks, your messages and messages to you.
• Fallback nicks when the master fail.

He also has something that I love in certain programs: separation of core and client.

What does that mean?

Basically, the program is divided into two, in the case of Quassel, the Core is who connects and does everything in the statement of the IRC. The Client only connects to the core and shows things to the User.

What is the advantage?

You can go online even staying offline :). When I get disconnected from the Core, it just put my nickname away, but stays connected to IRC, after all, who was disconnected is the Client(I), not the Core (which is on an external server). When I connect again it shows me everything like I never left. I can see everything that happened without needs a bot to log.

How to Install?

He is also the repository of most distributions.

• Arch Linux: pacman -S quassel
• Ubuntu or Kubuntu:
  • StandAlone(without separation of Core/Client): apt-get install quassel
  • Core: apt-get install quassel-core
  • Client: apt-get install quassel-client
• Gentoo: emerge net-irc/quassel

You can also run it on Mac OS X and Windows.

Results of namebench

Today in  ##ruby-br channel,  @diegorv send me an excellent tip, a program called  namebench do several tests on some DNS to find the faster. I've had an improvement of 69%.

If you want to try "by hand" in Linux, then install the package dnsutils, after you should have dig(/usr/bin/dig) command.  Usage is simply, dig any-site @ip-of-dns. Here my test, comparing my new default DNS and the DNS of Google.

Attention  to Query time, here the second DNS of Brasil Telecom(my ISP) is 25% faster than the Google, but you must remember the geographical distance.

See  here too.

Namebench is available in AUR(for Arch Linux users) and in getdeb.net(Caution: Outdated by today's date) for Ubuntu/Kubuntu users.

Garbage, garbage, garbage ...

Something that everyone has somewhere but no one likes. Consumes space, can leave slower and usually not useful.

Doing this manually is really a torture like to watch the cure for insomnia(ok, it's a joke)

In this case the best thing to do is to automate the task. Why not? After all, that time saved you can leave with his wife.

Mafagafos live in the trash the PC and they kill kittens

Recently I did a script for this, but it is somewhat basic, let's see something more complete.

Let's talk about Bleachbit (no, I'm talking about Bleach).

It removes unnecessary files or at least not as useful for the space occupied, it does so in both the system files and on more than 50 apps

Some widely used as Firefox, Amule, Java (Argh!), Internet Explorer (no, do not tell me you use), etc, etc, etc...

First, let's install:

• Arch Linux: yaourt -S bleachbit
• Ubuntu: apt-get install bleachbit
• Fedora: yum install bleachbit
• Windows: Go to site and finds a way

Huhu, 25% do espaço ocupado é lixo

See, was not so difficult (unless you use a certain system that makes you have to go to the site and download manually) on your menu should have 2 icons in system (if you use the system mentioned above, it should be in the middle of 316,327 entries that have their menu), one is to throw as normal User and the other as root (if you use "commom system" not worry, you do not mess with this thing called 'root', it is only responsible for preventing viruses steal your passwords and screw up your computer). With the root (which unfortunately has no powers of super-cow) you can also remove files from the system, it helps to have a thorough cleaning (especially if you have a pentium 4 that due to overheating caused by temperature 30 ~ 37 ° C (HERE IS HELL!) arrives to make a log of 100mb/hour).

As you can see on the screen it gives several options, and they appear only if needed, for example, does not appear the option of aMSN if I do not have cache of it :)
