I previously introduced the way of blocking the ad pop up of Avira AntiVir Personal 8.0. However, this method can’t block the ad of version 9.0. Here is the solution:

I use Windows Vista Business to perform the following steps.

  1. Click Windows Icon (or Start) > Control Panel >Administrative Tools >Local Security Policy.
  2. After Local Security Policy MMC has opened, you can click Additional Rules under Software Restriction Policies.
  3. If you cannot find Additional Rules, you can right click Software Restriction Policies and click New Software Restriction Policies.
  4. Then, right click Additional Rules, and select New Path Rule. Then, you will see a new dialog box. Then, click Browse… to select C:\Program Files\Avira\AntiVir Desktop\avnotify.exe.
  5. Make sure the security level is set to Disallowed. Finally, you can click OK button.

I hope this screenshot would be helpful.

Yesterday, I wrote three very simple programs in different programming languages including C++, C# and Java. These programs will use trial division method to find 200000 prime numbers that is starting from 2 orderly. Then, the found prime numbers will store in an array. I found that C++ has the best performance, and the next are Java and C#. However, you don’t need to take the test seriously. I know this test can’t represent the whole performance of C++, C# and Java. And it ’s just for fun.

Compilers:

C++
MS 32-bit C/C++ Optimizing Compiler Version 15.00.30729.01 for 80×86 and
MS Incremental Linker Version 9.00.30729.01
compilation command: cl /EHsc /Ox primeN.cpp

C#
MS Visual C# 2008 Compiler version 3.5.30729.1 (.NET Framework 3.5)
compilation command: csc primeN.cs

Java
Java SE Development Kit 6 Update 11
compilation command: javac primeN.java

Environments:

OS: Windows Vista Business SP1 (32bit)
CPU: AMD Athlon 64 x2 5400+
RAM: 4GB

Result:

WordPress 2.7 build-in revision feature to save all backup articles (or you may call posts). However, the backup articles almost will not be used and a lot of database storage is wasted. Therefore, I disabled revision feature in my blog. Here is the solution to turn this feature off.

  1. Edit wp-config.php that is saved in WordPress root directory.
  2. Add the following red statement at wp-config.php. It’s suggested to add the red statement at the last 2 line (before ?>).
    ...........
    require_once(ABSPATH . 'wp-settings.php');
    define(’WP_POST_REVISIONS’, false);
    ?>

If you have wrote many articles previously, I believe your database has already stored many unnecessary articles. To release the storage, it is suggested to remove the existing revision articles.

  1. Go to phpMyAdmin
  2. Click SQL button:
    phpmyadmin_sql
  3. Enter and submit the following SQL statements:
    DELETE FROM wp_posts WHERE post_type = "revision";
  4. Finally, phpMyAdmin will show you how many revision articles have been deleted:
    deleted
  5. If error occurs, you should substitute wp_ to the table prefix of your WordPress

Komodo Edit is a free and open source text editor. I like using Komodo Edit to develop my PHP programs, XHTML and JavaScript. If you hate remember functions name, variables name and functions parameter and so on, Komodo Edit is a good choice because it offers autocomplete feature. If you like Visual Studio, I believe you will enjoy Komodo Edit as well.

By the way, NetBeans also provides this feature. If you want to try alternative PHP Editor, NetBeans seems also a good choice.

Block AntiVir Ad

February 10th, 2009

Avira AntiVir Personal is a free anti-virus software, but it always displays Ad banner when the virus definition is updating. I’m currently using Windows Vista Business and it works. However, I don’t know whether Windows Vista Home (Basic/Premium) or Windows XP Home Edition can do it by the following method.

  1. Click Windows Icon (or Start) > Control Panel >Administrative Tools >Local Security Policy.
  2. After Local Security Policy MMC has opened, you can click Additional Rules under Software Restriction Policies.
  3. If you cannot find Additional Rules, you can right click Software Restriction Policies and click New Software Restriction Policies.
  4. Then, right click Additional Rules, and select New Path Rule. Then, you will see a new dialog box. Then, click Browse… to select C:\Program Files\Avira\AntiVir PersonalEdition Classic\avnotify.exe.
  5. Make sure the security level is set to Disallowed. Finally, you can click OK button.
