Checking the links to your site (from affiliates) using cron and bash script.

If you have some affiliate links and are concerned about their presence then you can setup <a class="zem_slink freebase/guid/9202a8c04000641f80000000045c9c5b" title="Cron" rel="wikipedia" href="http://en.wikipedia.org/wiki/Cron">cron to check the links for you regularly. For this you need a very simple script (as below) and a cron entry (example further down).

Using SSH-keys to connect to a server – Putty,Solaris,Linux

Generating the ssh dsa  keys

ssh-keygen -b 1024 -t dsa
When this command is executed on your local machine, it will ask you for a passphrase and generate
a 1024 bit long (-b 1024) public/private dsa (-t dsa) key pair with the ssh-keygen command.
You can also create a rsa key (-t rsa).
You can leave out the bit length parameter (default bit length is 1024).

In case you don&#8217;t like the standard key name you can specify a name using the -f name parameter.
In the process you are asked for a place to save your keys. I kept the standard path. Then you are asked for a passphrase.
Now there are two paths which you can follow :
a) the short, easy but insecure way: use no passphrase, have easy access to your remote-server, feel paranoid about someone stealing your private key
b) the a bit longer, slightly less comfortable but secure way: use a passphrase, use ssh-agent and feel safe

command not found – packagekit plugin

If you run into problems where you run some command and the command is not found and you have to install it and run the program again then why not use the command not found <a class="zem_slink freebase/en/plugin" title="Plug-in (computing)" rel="wikipedia" href="http://en.wikipedia.org/wiki/Plug-in_%28computing%29">plugin for Packagekit. Here is the description:

Pimp your ls

Here are some of the things that you can do with your ls command.

First off you can use alias&#8217;s to help you type the most typical ls commands. I will give you some examples:

alias ls =&#8221;ls –color –classify&#8221;
alias ls.=&#8221;ls -d .*&#8221;

Very commonly used :

  <td>
    <div class="text codecolorer">
      alias ll="ls -lhvrt"<br /> lsd="ls -lUd */" # List directories only
    </div>
  </td>
</tr>

And after all this you can download the l script from pixelbeat. Quite interesting:

Firefox Disables Microsoft .NET Addon

Firefox Disables Microsoft .NET Addon ZosX writes &#8221;Around 11:45 PM Friday night, I was prompted by Firefox that it had disabled the addons that Microsoft has been including with .NET — specifically, the .NET Framework Assistant and the Windows Presentation Foundation. The popup announcing this said that the &#8217;following addons have been known to cause stability or security issues with Firefox.&#8217; Thanks, Mozilla team, for hitting the kill switch and hopefully this will get Microsoft to release a patch sooner.&#8221; Here&#8217;s the Mozilla security blog entry announcing the block, which Mozilla implemented via its blocklisting mechanism.
