It is a matter of showing only one side of the box-shadow at a time, and so you need two box-shadows (one for each side of the block you wish to have shadows, and we can put both CSS codes in the same property).

Here is an example that should be compatible with Firefox, Chrome and Opera.

box {
    -moz-box-shadow:
        inset 5px 0 5px -5px #333,
        inset -5px 0 5px -5px #333;
    -webkit-box-shadow:
        inset 5px 0 5px -5px #333,
        inset -5px 0 5px -5px #333;
    box-shadow:
        inset 5px 0 5px -5px #333,
        inset -5px 0 5px -5px #333;
}

Here is the result:

And I used to package it before, so it took me not very long to update the package to the newest version.

Fetchyahoo is a script written in Perl which fetches your email from Yahoo! Mail and either saves it in your mbox or can also send it to an IMAP folder. It pulls email using the web interface which is very useful for those with Yahoo Mail who do not have POP3 or IMAP access, since POP3 access for Yahoo Mail seems to be a paid service.

The deb package for fetchyahoo 2.14.0 is available from my PPA. You can either add it to your sources.list:

sudo add-apt-repository ppa:weboide

or you can directly download it from launchpad:
fetchyahoo_2.14.0-0ubuntu1_all.deb

DudaLibre just launched a new campaign called "We are more than 1%" to attempt to prove wrong the Press and most of people's opinion about Linux's world market share not being more than 1%.

Make sure you get counted and that you share the link with your linux friends!

  • msttcorefonts: the Microsoft-like fonts. If you have those installed, Firefox will use them and you will get ugly windows-like font on most websites which I personally hate.
  • wine: Application to run windows programs on linux. For security reasons.
  • postfix: a mail server. Just because I do not want to run a mail server on my netbook.
  • ...and some other

The best way to restrict those packages from being installed is through Apt Pinning.

Apt pinning

It is very easy to pin packages and restrict them from being installed.
You will need to edit /etc/apt/preferences and add something like this:

Package: msttcorefonts
Pin: version  0.0
Pin-Priority: -1
 
Package: ttf-liberation
Pin: version  0.0
Pin-Priority: -1
 
Package: ttf-mscorefonts-installer
Pin: version  0.0
Pin-Priority: -1
 
Package: wine
Pin: version  0.0
Pin-Priority: -1
 
Package: postfix
Pin: version  0.0
Pin-Priority: -1

Pin-Priority: -1 restricts the given version from being installed, and the version 0.0 does not exist and should be a lower version than any versions of the given packages. As a conclusion, they will never be installed.

Be careful what you pin, though, as you might be too restrictive and could prevent installing or upgrading other useful packages.

It is important to optimize tables to reduce data fragmentation.

mysqlcheck -Aop -uroot

If you are not using root replace it with your username.

-A : Check all tables in all databases. This is the same as using the --databases option and naming all the databases on the command line.
-o : optimize the tables.
-p : Prompts for a password to use when connecting to the MySQL server.
-u : The MySQL user name to use when connecting to the server.

Inspired by this article.
