Tutorial

After you have installed Drupal and created first user account (will considered as administrator/super admin by drupal system) then you have to configure few things.

Click on the menu item that says "Administer", its on your left sidebar. That will lead you the the Drupal admin screen. You will find some menus: Administrer, Content management, Site building, Site configuration, User management, Reports and Help.

There are some basic security configuration you should to know before you create content and publish your site to the world.

1. Home -- Administrer -- User management -- User settings

    By default drupal site will choose "Visitors can create accounts and no administrator approval is required." for you. Change

PDF documents can be protected by the creator by disabling some functions such prevent printing, copying or editing the documents. Thats the reason why most users choose PDF format to share and transfer documents. They need to keep their content from being copied or stolen.

There are several ways to remove this PDF protection. You can use online or offline ways.

1. Online Ways

I found two good sites that offering a service to unlock your PDF files, PDF Cracker and PDF Filler . Both sites will ask you to upload your PDF files and all you do is just wait them finish their jobs.

Details:

Good news for you who got infected by new GPcode virus, Kaspersky Lab now able to provide infected users with instruction on how to recover files attacked by the GPcode.ak virus. It give a new hope although they are not able yet to cure your system 100%.

Had a shutdown problems? Perhaps you can try this. It works for me. One of my friends can't turn off her computer although she had click Shutdown button. I find it here.

Start Regedit and navigate to

HKEY_LOCAL_MACHINE\Software\Microsoft\Windows NT\CurrentVersion\Winlogon

Set the value of PowerDownAfterShutdown to 1.

About GPcode

Gpcode is a trojan that encrypts files with certain extensions on local and remote drives and then asks a user to contact its author to buy a decryption solution. And now Kaspersky Labs report that a new version of GPcode (also known as PGPCoder) is in the wild, this time with a successful implementation of RSA 1024-bit encryption.

New Variant

With implemention of RSA 1024-bit key, new variant of GPcode will give a real test for antivirus vendor. Researchers estimate it would take around 15 million modern computers, running for about a year, to crack such a key. Will be a huge challenge isn't it?

Have you ever found this error in your site ?

I found it today in one of my sites. It occur when I try to open menu in Site Building and Site Configuration menus. Seems there are connection problem between my site (using drupal) and MySQL server. Someone in drupal forum guessing this maybe because two problems, which result in the same error:

This morning, I got this message in one of my sites 'erakomputer':

Table './erakomp_drpl1/cache_menu' is marked as crashed and should be repaired query: SELECT data, created, headers, expire, serialized FROM cache_menu

I don't know what's wrong with my site, there's nothing wrong when I open it last night but suddenly this morning that message has flooding my site pages. Thanks God Drupal Forum give a solution for this. They said it was problem with one of tables in MySQL database. They guess if the hosting machine crashes (i.e. does not get shutdown cleanly), this can happen. They suggesting I need to run the REPAIR command from mysql or phpMyAdmin.

How to repair it :

The table need to repair is cache_menu table.
