This is a very short post about removing the SVN files and folders from your directories.

find ./ -name ".svn" | xargs rm -Rf

Ubercart 2.x introduced a new way of handling product prices. It is called price_handler().

This is very nice, and most of the discount and TAX modules are using this new function to override the product price, but what if you need the new price and the old price on the same product?

Let's say you would like to show your visitors the product price before it was discounted.

You obviously should not change the condribution modules or the Ubercart core. You should just simply create your own module or use the general module you have created earlier (You got one, right?) and just paste the following lines at the bottom.

This function will create the price handler. Don't forget to replace 'your_module' with your module name everywhere.

/**
 * Implementation of hook_uc_price_handler().
 */
function your_module_uc_price_handler() {
  return array(
    'alter' => array(
      'title' => t('Old price handler'),
      'description' => t('Adds old price to product.'),
      'callback' => 'your_module_price_handler_alter',
    ),
  );
}

 

This function will save the original Sell Price and put it on the node object for further use.

/**
 * This is just a function to save the original sell price and put it on the node.
 */
function your_module_price_handler_alter(&$price_info, &$context, &$options) {
  if (isset($context['subject']['node']) 
    && $context['subject']['field'] == 'sell_price' 
    && !isset($context['subject']['node']->old_price)) {
    $node = $context['subject']['node'];
		$context['subject']['node']->old_price = $node->sell_price;
  }
}

Cron is a time-based job scheduler in Unix-like computer operating systems. 'cron' is short for 'chronograph'.

If you would like to set up your Drupal and linux server to use the cron, these steps will help to achieve your goal.

Open up a console and change to the user which will run the cron.
Every user has it's own cron tab (which is the list of jobs cron has to run.)
If you prefer, create a new user for this job.

To access your crontab use the following command:

crontab

This will give you a summary of crontab's commands and switches.

To list your cronlist type:

crontab -l

and to edit the list:

crontab -e

If this is the first time you edit the crontab, it will ask you which editor you would like to use.
If you are unsure, use google to find out which editor is the best for you.

Inside the editor, add the following line to the end of the list:

*/5 * * * * /usr/bin/wget -O - -q -t 1 http://[your server url]/cron.php

This will execure the cron.php in every 5 minutes.

Here is a diagram of the general crontab syntax, for illustration:

*    *    *    *    *  [command to be executed]
|    |    |    |    |
|    |    |    |    +----- day of week (0 - 6) (Sunday=0)
|    |    |    +------- month (1 - 12)
|    |    +--------- day of month (1 - 31)
|    +----------- hour (0 - 23)
+------------- min (0 - 59)

* in the value field above means all legal values as in braces for that column.
The value column can have a * or a list of elements separated by commas. An element is either a number in the ranges shown above or two numbers in the range separated by a hyphen (meaning an inclusive range).

A free implementation of an NX server based on NoMachine's libraries named FreeNX was published in 2004 by Fabian Franz. FreeNX's primary target is to replace the one closed component and is written in a mix of several thousand lines of BASH, Expect and C, making FreeNX difficult to maintain.

Last week, Google Code released the source code of their own proof-of-concept implementation of an NX server, Neatx. Designed from scratch with flexibility and maintainability in mind, Neatx minimizes the number of involved processes and all code is split into several libraries. It is written in Python, with the exception of very few wrapper scripts in BASH and one program written in C for performance reasons. Neatx was also able to reuse some code from another Google Open Source project, Ganeti. The code still has some issues, but we're confident interested developers will be able to fix them.

Also, Neatx implements features not found in FreeNX, such as the drop-down menu for session control in rootless sessions. At the same time, not all of FreeNX's features are implemented in Neatx.

Only one week after the first beta was released, VirtualBox developer Frank Mehnert has announced the availability of the second beta of version 3.0 of the open source desktop virtualisation application for x86 hardware.

Start using VirtualBox 2.x USB support by following these easy steps.

It is time to revise my 42droids blog and rewrite it in Drupal 6. I already started this project and expect to finish it next week. (If I can finish off the mercure project early next week.)

This post is not about the new Ubercart release but about hiding the Qty. field on the cart page. ;)

add this code to your new/old module to make the Qty. field go away.

<?php
function mymodule_form_alter(&$form, $form_state, $form_id) {
	if ($form_id == 'uc_cart_view_form') {
		//This line disables qty column
		unset($form['items']['#columns']['qty']);
		//This loop denies access to all qty fields for the form
		foreach($form['items'] as &$item)  {
			if (is_array($item) & isset($item['qty'])) {
				$item['qty']['#access'] = 0;
			}
		}
	}
}
?>

If you got one or more of the following errors try to use the command below:

perl: warning: Setting locale failed.
perl: warning: Please check that your locale settings:
	LANGUAGE = (unset),
	LC_ALL = "en_GB.UTF-8",
	LANG = "en_GB.UTF-8"
    are supported and installed on your system.
perl: warning: Falling back to the standard locale ("C").
locale: Cannot set LC_CTYPE to default locale: No such file or directory
locale: Cannot set LC_MESSAGES to default locale: No such file or directory
locale: Cannot set LC_ALL to default locale: No such file or directory

Try to reinstall the local languages: (english pack)

sudo apt-get install --reinstall language-pack-en

In Drupal 5.x with the Views module we can easily create content listing blocks. There is an option for switching on the "more" link on the Views edit page. If you would like to change the word "more" to something else, you can add the following code to your template.php in the theme folder:

/**
 * Override the more link on view block
 */
function phptemplate_views_more($url){
   return "" . l(t('[Read more]'), $url) . "";
}

Don't forget, that this function will override every "more" link on every block.
If you would like to theme only one "more" link, you have to come up with a better idea. Sorry :)

To clone a Virtual Machine in VirtualBox, first go to:

/home/[username]/.VirtualBox/VDI

in the console, use command:
(don't forgot to change the virtual disk name to your existing virtual disk name.)

VBoxManage clonevdi vm1.vdi vm2.vdi

The creative cats and kittens at Obscura Digital have put together a stunning piece of performance art / data manipulation demo which combines their proprietary multi-touch software with Musion's Eyeliner 3D holographic projection system. Like that BMW installation we saw recently, this is one of those odd combinations of technology and art which is best seen in action rather than described -- so check out the video after the break and see the work in all its mind-bending glory.

There's lots of innovation going on in security - we're inundated with a steady stream of new stuff and it all sounds like it works just great. Every couple of months I'm invited to a new computer security conference, or I'm asked to write a foreword for a new computer security book. And, thanks to the fact that it's a topic of public concern and a "safe issue" for politicians, we can expect a flood of computer security-related legislation from lawmakers. So: computer security is definitely still a "hot topic." But why are we spending all this time and money and still having problems?

Sam: So, that £5 gorgeous sketchbook I bought today?

Megnéztem a Juno c. filmet, s hát be kell ismernem, a legjobb film volt amit mostanában láttam. A történet nagyon tetszett és a zene is isteni. Csak ajánlani tudom mindenkinek. :)

Szóval, ja. már jó régóta nem jelentkeztem, tudom. De, az életem mindenféle furcsa kanyarokat vett, így aztán nem volt innyemre való blogot írni. Most viszont megteszem. Talán csak pár szóban, talán hosszabban.
