3rd button of one of my SGI gray mouse dies...

I've got those 3 button mice from SGI as I was working with Indy's and O2's. I also have keyboards. Those are real good quality!

Yesterday, I tried to right click and somehow, nothing happened. At first I thought maybe it was X going banana, but trying again and restarting did not change anything. I reset my KVM too, just in case. Still nothing.

Access 2007, or where are my menus?!

My Boring Story

Microsoft Office is making progress... or... is that really progress?!

I got a great little surprised when I met face to face with Access 2007 and all the menus were gone. I wasn't warned about that one! Not only are they gone, you MUST use little tiny icons in the place of menus so it takes you an awful long time to learn the icons, but not just that, YOU have to choose which icons will appear on your toolbar.

Actions in Drupal, or should I say Rules?
I spent hours today to find this one module: Rules.

In most cases, you can set up a rule in Drupal with their Actions and Triggers and it will work just fine. The fact is that these options are extremely limited if you want any kind of condition on the Rule before triggering the action.

The idea is very simple:

1. Something happens

2. Check whether it is of interest1
- 1. This part is what is missing in Drupal Core v6.x

Ada Variables

Ada variables are complex objects. When developing a compiler, you must definitively take that in account. You have several sides to your variables: one you need to be able to handle dynamic variables since the compiler will have to be capable of doing all the operations on all the constant variables just as if you were executing your program and it has to handle all the tests necessary to ensure integrity.

So... we need a library that can handle integers, a library to handle floating points, a library to handle arrays, etc.

Adding links to your node features in your views when using Drupal 6

Several times, you may have been creating views and wondered: how the heck could I add a link to my node Edit page, or if you are like me, my node Outline, Track, Convert pages on top of the Edit page.

This is actually pretty easy.

To your fields, add a Node: Nid then click the Add button at the bottom.

In the setup of the field, select Rewrite the output of this field and enter the text of the link as it should appear (i.e. 'Edit' or 'Convert'.)

AddThis weird behaviors

I just switched my websites from one server to another and noticed that on my main company site (http://www.m2osw.com) I would get a # at the end of the URL. Automatically added somehow. Thinking that could be a bad guy I checked the code and could not really see anything.

Hitting "Back" once, I noticed that the # would be transformed to #atssh-digg. I don't have anything specific about digg on that page except the AddThis button. That adds Digg among some 150 different systems where you can share my pages.

Managing your own Drupal Download Site

The other day, I was thinking, it would be nice if I could find the way to manage my own download site so people who use my modules that I do not provide directly on http://drupal.org would still show as expected (i.e. Green in the update window).

I found this page about it: http://drupal.org/node/210984

This is done by creating a service in your Drupal environment. You should use the ready made script named:

A firewall inside Apache

If you are running a webserver, you should use a webserver firewall. This prevents many attacks from being perpetrated on to your servers without the need to make your own applications more complex than necessary.

The idea is very simple, if you have a few people who can edit your data from the Internet and those have a static IP address, you can check that the editor pages are only accessible to those IP addresses. Any other access can simply be blocked.

an unknown filter was not added: DEFLATE
I have been wondering, for a while, why is it that I get errors about DEFLATE no being known.
```
  [Sun Apr 11 22:41:23 2010] [error] an unknown filter was not added: DEFLATE
  [Sun Apr 11 22:48:54 2010] [error] an unknown filter was not added: DEFLATE
  [Sun Apr 11 22:50:23 2010] [error] an unknown filter was not added: DEFLATE
```
I should have thought of it, the deflate module was not installed. That was it, but oh well... 8-)

To tweak your Apache setup, use the following two lines:
