Cleaning the boot sector of the hard disk

Many times when we install multiple operating systems simultaneously on your computer, such as Windows and Linux, we need programs that are stored in the boot sector so that when you turn the computer can select the system opertivo we want to work with, some of these programs boot sector managers are GNU GRUB or Lilo , now, how do we remove these managers start? the solution:

From Windows press Windows key (window) + R or Start button and Run ... and type in the command line fdisk / mbr , this option (master boot record) or master boot sector is responsible for booting the operating system correctly. This program takes care of loading into memory and run the rest of the system. Also here the bootloaders so you can delete the entire contents of this sector for the next reboot of the system is rebuilt.

Certain viruses that stay in the boot sector and then into memory can cause irreparable damage to your computer. You can remove them with FDISK / mbr.

To learn the status of your disks and partitions using the following command: FDISK / status .

Install MAME emulator in Debian / Ubuntu

MAME is an emulator for those games, at least people my age-old used to play on the famous corner arcades.And many still remember those long hours of fun in front of the arcade machines with games like Metal Slug , Double Dragon or Super Sideckicks .

To my pleasant surprise, the blog of A Bionformatiquillo I learned that there is a version of theMAME emulator for GNU / Linux , or at least for Debian and distros based on it like Ubuntu or LinuxMint. To install it, just follow these steps:

Open a terminal (console) and type the following to install the emulator and all the necessary files:

$ Sudo aptitude install xmame-sdl xmame-common

After installing the MAME emulator, we download a frontend to run it in GUI by typing:

$ Wget http://surfnet.dl.sourceforge.net/sourceforge/gxmame/gxmame_0.35beta2-1_i386.deb

Once downloaded the frontend, just unpack it and install it with the command:

$ Sudo dpkg-i-1_i386.deb gxmame_0.35beta2

Speed ​​up Firefox 3 on Linux

Besides the already known tricks to speed up Firefox , version 3 of this fabulous browser can alsoaccelerate its local operation , optimizing the behavior of the awesome bar that is displayed in the address bar when typing a URL.

This awesome bar in linux, use the database SQL Lite system to store and save data from websites and URL's related, so each time you use the address bar to enter the name of a website or address URL that you have visited, are consulted to SQL Lite database.

Over time, we can see that Firefox is slow it can get through the awesome bar, which fills with information. An interesting option is to optimize the database for SQL Lite Firefox 3 , to improve speed. And this is done by running the following command in Terminal:

for f in ~ / .mozilla / firefox / * / *. sqlite, do sqlite3 $ f 'VACUUM;'; donate

Personally I've tried and true that my Firefox 3 has gained a lot of speed with respect to how it was before. Of course, doing this little trick is completely safe, as only compact the SQL Lite database.

Thank Gabuntu the trick.
