First, you have to enable two options on Labs (don’t know what’s Labs? Go to the end of the post, later came back).

Enable “Canned responses”:

And “Inserting images”:

So, click on “Compose Mail” and write a blank mail, just with your desired signature:

Then insert the image you want (look the button selected above):

It will be something like that:

Then you save you canned response:

And name it (please, a good name, easy to remember):

And this is it! You have created you signature with image!

And how can I use?

Well, write anything… Like that:

Then, insert your canned response:

And your mail will be something like that:

This is it.

Like Google says: “Gmail Labs is a testing ground for experimental features that aren’t quite ready for primetime. They may change,break or disappear at any time.”

In a short way, Labs are very nice add-ons to your mail. Be careful, it addicts.

Wow! I’m amazed! How they can do something so cool with just three circles (or elipses)?? If you want to buy one to send me, the link is: https://shop.canonical.com

See the video:

Ubiquity for Firefox from Aza Raskin on Vimeo.

According the post, “since Firefox 3.0, bookmarks, history and most storage is kept in SQLite databases”. So, optimize this databases is very healthy to Firefox.

And it’s very easy to do. On Ubuntu (I did on 9.04) install the sqlite3 package. Open the terminal and type:

sudo aptitude install sqlite3

After, still in terminal, access your Firefox profile folder:

cd ~/.mozilla/firefox/something_weird.default

In my computer, this something_weird.default is 73cm0ffy.default.

You can see many .sqlite files inside this folder, these are the database to optimize. To do this, close Firefox (only after read or copy this post ), then type, for each file:

sqlite3 file_name.sqlite vacuum

And there’s a way to vacuum all the files at once? Sure. You’re using a Linux terminal! To do this, type:

for i in *.sqlite; do sqlite3 $i vacuum; done

And done.

The solution: Burn a CD? No. Let’s do something more criative…

Well, we know that Windows XP also has his boot list (boot.ini), so why not to put Linux on the list?

Unfortunately, it’s not so easy as edit the grub menu, but it’s still easy.

First, you have to create an image from the master sector of a HD which has the grub installed (I used my notebook). Open terminal and type:

sudo dd if=/dev/sda1 of=bootsect.lnx bs=512 count=1

Maybe you have to change /dev/sda1 for other device, depending on your HD.

This command creates the bootsect.lnx file. Put it on c:\ on Windows. After that we will edit the boot.ini on Windows.

There’s two ways to do this: you can edit the c:\boot.ini directly (it may be hidden and read-only) or you can right click on “My Computer”, go to “Preferences”, “Advanced” tab, and click the button to edit boot preferences. So the boot.ini is opened on notepad.

On boot.ini, paste the following line at the end of the file:

c:\bootsect.lnx="Linux"

Save, close and reboot.

Now your Windows asks you if you want to start Windows or Linux.

And voi là.

(I think it’s the biggest post I wrote in English, so forgive me for the mistakes)

So I “googled” about Evince and Firefox and found it quickly in the Lâmpada Azul site. Altought it has many steps, I used only the first and it worked very well. You have only to install the mozplugger package:

sudo aptitude install mozplugger

Alright. It may works now.
