.bashrc functions to do repetitive tasks

Submitted by admin on Sun, 01/31/2010 - 16:01

A cool thing to do if you find yourself doing something LOTs of times:

Edit your ".bashrc" (in your home directory)
and create your personalised script as follows:

wch()
{
sudo chmod 774 $1 $2 $3 $4;
sudo chown www-data.www-data $1 $2 $3 $4;
}

Then you can execute the command "wch" with parameters to execute the commands you want. Very cool...

See "Joe's" comment here: http://drupal.org/node/139915

Go to [Content management] > [Content types] > [Manage fields] and make sure yiour image field is LIGHTER than [body] eg -2
this will force the image above your teaser but not yet inline

then go to modules > system > defaults.css

and add

.field-type-image img {
float: right;
margin-left: 1em;
border: 0px solid red;
}

Note: my CCK image field is called "image" and I choose to float it right, adjust yours to suit your tastes.

Enabling TELNET in Windows 7

Submitted by donmc on Wed, 01/27/2010 - 10:33

It turns out that by default TELNET was not packaged with Windows 7. Apparently this was also true for Windows Vista.
Telnet is known to be insecure and so by default, Microsoft now DISABLES any likely security holes. Whenever you can, you should always use SSH.
That being said, you can enable Telnet this way:

  1. Start
  2. Control Panel
  3. Programs And Features
  4. Turn Windows features on or off
  5. Check Telnet Client
  6. Hit OK

After that you can start Telnet via the "CMD" - Command Prompt.
