Vacuum your Firefox databases for better performance
Jul 27th
A few days ago I marked an article to read later and I finally read it. It’s about how to Vacuum your Firefox databases for better performance.
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.
Starting Linux through Windows XP boot list (boot.ini)
Jul 22nd
Last week I had to recover the grub in a notebook after a Windows reinstall. The easiest way would be running an Ubuntu live cd and run the grub program. But I hadn’t a cd and tried with a bootable usb stick and… nothing. That notebook doesn’t boot by usb. I tried also with a sd card, but had the same problem…
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.

How to open PDFs inside Firefox on Linux
Jul 19th
I was thinking about how to open a PDF file inside Firefox on Ubuntu, like the Acrobat plugin do on Windows, but using Evince.
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.
USB sound card on Ubuntu
Aug 6th
Last week I had to install a M-AUDIO Fast Track Pro USB sound card on a computer with Ubuntu. Well, I’m not so good on audio subjects, so I asked Oraculo about ‘m-audio fast track ubuntu‘, where I found some good info.
But, to ease your work if you have to install such sound card, I wrote a step-by-step tutorial on how to install it on Ubuntu 8.04:
- Step 1: Plug the sound card on the computer via USB.
Thus, I finish the step-by-step tutorial.
When I connected the sound card, I looked what dmesg said. As I connected the USB, Ubuntu has registered the driver needed. So I tested and everything seemed ok.
Don’t you wonder why some operating systems ask you to install the driver from a CD?
Using Nokia 6110 on Ubuntu
May 19th
On my last post I wrote about how to use your cell phone as a remote control on Ubuntu. On it, I wrote about how to use a modest cell phone (with bluetooth at least) to control OpenOffice.org presentations, games, etc.
Now I’m talking about a more advanced cell phone, the Nokia 6110. I started with file transfer. See how it is a simple thing to do on Ubuntu…
Using data cable
With any USB -> mini-USB data cable (it is included on cell phone pack), you just plug one side on the phone and the other side on the computer. The cell phone will ask you about connection type. Choose “Data trasfer”.
And voi lá, Ubuntu mounts it as a drive, like it does with a pen drive.
Using bluetooth
Right-click on the bluetooth applet (near the clock) on Ubuntu, then choose “Explore drive…”. Select the cell phone and answer it on the phone options (it will ask you a password that you define for the connection). And voi lá again, Ubuntu mounts it as a drive, like it does with a pen drive.
I prefer use the bluetooth way, because it’s simpler and it gives you the option to access the phone memory or the memory card as different drives.
On my next post I’ll talk about how to use Amora on this phone.
Epson Stylus C92 on Ubuntu Gutsy (7.10)
Jan 30th
Yesterday I bought a Epson Stylus C92 printer (finally!). I will share about how to install it on Ubuntu.
![[Foto]](http://lh3.google.com/drenoel/R5_5y5_0_fI/AAAAAAAAAI8/v5A0BIWWpTg/s800/epson0.JPG)
First unpack it (the manual told to do so)…
Uh, another important thing the manual says is: Do not drink the ink!
After “unpack” as the manual says, plug the USB on the computer.
Wait 2 seconds.
Alright! Ther printer is now installed.
However, the C92 driver still isn’t on the foomatic package (accordind OpenPrinting database). Gutsy installs it with C88 driver, so it doesn’t works.
I tried to follow the instructions provided by OpenPrinting (ex-LinuxPrinting.org), and tried what they say on some foruns, but still doesn’t work.
So I installed TurboPrint. The driver works very well, but I’m not fully satisfied ’cause it’s not free software. I believe that soon it will be on foomatic or gutenprint.
So do this: download the turboprint driver (you could just click on “open with”, if you want to). Open the downloaded .deb file (will appears a window like that):
Click on “Install Package”.
After install it, you must just change the driver on the printer setup. Go to System > Administration > Printing. Select the printer e click o “Change” to change the driver:
After it, select Manufacturer and the option Epson_StylusC9x:
Go next and next… Your printer might be correctly installed on this moment. Print a test page and hug someone near you.
