Intro
Git, one of the big known versioning systems, has been in the last couple of years steadily impose itself as the standard solution, slowly overtaking the more traditional SVN.
Github.com has certainly done a great job in providing a stable environment and a community hub where Git could spread. But that alone doesn't explain git's popularity. One particular feature makes Git diffrent from the traditional SVN: it is a distributed system. That might not sound like much, but it's opening the way to more flexibility and ease of use.
However, git can seem a bit hairy to the typical programmer familiarized only to the very basics of versioning systems (skills necessary to work on a project).
I have experimenting a little with git, my purpose being to use git as a fully functional automated production-staging-development workflow.

For valuable work on creation of sites you need a good comfortable editor necessarily.
Suppose we have a Drupal site and an external application, and we want to use the same login for both. For example, we have an application which does something, but we have our users handled by Drupal, and we need to pass over to the application the information about the current user.
Basically we need to tap into our Drupal's user database table. We also need to use Drupal's $_SESSION, but Drupal stores its sessions in the database by default, and the $_SESSION superglobal remains empty. Instead, we need to use the global $user variable.
Taking this one step further, why not synchronize the logins? By synchronize I mean if we log in into Drupal, we get logged automatically into the application, and vice-versa, when we log in the application, we get logged into the Drupal site automatically . That way, if we navigate from app to Drupal, we don't have to relogin.

If you want a simple speedometer chart, and google's chart is just not what you want, here's a simple custom solution written in PHP. This should allow you to make any customizations you want.
If you're in the need of a bad-words validation, you might have thought first about an input filter, since Drupal is so into that.
To put it simply, it's better to educate the users instead of having them censored.
Installation
- install JasperServer - bundles java based applications (tomcat, ant) but also mySQL and iReports (don't need to install those on the server)
- to work with the reports, you'll need to install it locally as well
- to generate scheduled reports from php, enable SOAP extension for php (php.ini)
- install SOAP and Net_Dime PEAR libraries for php
- open IReports: add/create the SQL query, design & build the report
- start jasper server (tomcat)
- open jasper
The N jugs of watter in a classical problem in AI:
Given n jugs of watter, determine the fastest way to obtain a given volume. The only permitted operations are:
- you can empty a jug on the ground
- you can fill up a jug from the tap
- you can poor from one jug into another until wither the jug you're pouring into gets filled up or the jug you're pouring from gets empty
All the jugs are initially empty.
This is an example of how the solution looks like for a n=2 jugs, having volumes 5 and 3 while the volume to be found is 4:

If you host your site on a VPS or dedicated server, then you are able to tweak your server and make your site load significantly faster. The fallowing considers a LAMP platform but some parts might be useful for other platforms as well.
The first thing to consider is a PHP accelerator. I recommended eAccelerator. It will not make your site go significantly faster, but is one of those things that you have to have.
Second thing to do is a little database optimization.
If you want to restrict access to a directory, then think .htaccess and http authentication.
This is a solution when http authentication is not an option or if you want to restrict access to a single php script file.
It emulates regular http authentication with all the power & flexibility you get from php.

So, Drupal 7.0 Alpha 3 has been released on 21 Mar 2010. That's very close to a Beta and a stable release.
That's very exciting news indeed.
Besides CCK, Views and a number of well established modules as a part of the core, it has a large number of improvements in terms of usability, security and performance. Unfortunately, looks like Panels, a very cool module that for basically doing complex visual layouts won't be a part of D7. Hopefully, a release for D7 as a standalone module will be available soon.
