And if you are like me who like set it to Details view, you will often faced with a column or more which don't enough to display the informations. The information can be file name, file size or else. To expand them, usually I click column header and then drag it until they are expanded.

httpd.conf file is Apache server configuration file. In that file you can configure Apache server settings. You can to install Apache HTTP server in many OSes. And I ever install it on Mac OS X and Windows XP. And Apache doesn't provide a GUI configuration screen so you must find the httpd.conf file and then open it with text editor application such as notepad to configure it.

On Windows XP you can find the httpd.conf file in conf folder inside installed Apache folder (if you installed on its default folder so you can find it in : C:\Apache Software Foundation\Apache2.2\conf\ folder.
And on Mac OS X you can find the httpd.conf file inside folder: /etc/httpd/folder.

Windows XP has many startup points locations. From Startup folder inside Start Menu, Win.INI and registry. This time, I want discuss about startup points in registry because many viruses infected and put its trigger string in registry value so as the virus will triggered every you restart computer.

To look your startup program which triggered by registry, open your Regedit first by click Start - Run menu, type regedit in box and then press Enter key. Regedit has some startup keys location:
1. HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Run. In this key every string inside it will run every startup.
2. HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\RunOnce, in this key every program inside it will run once and registry will remove it after executed.
3. HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\Run, this key has same function with point 1 but if in HKEY_CURRENT_USER will run on your account only but in HKEY_LOCAL_MACHINE will trigger on every account on your computer.
4. HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\RunOnce,
this key has same function with point 2, but startup item in HKEY_LOCAL_MACHINE will trigger on every account on your computer.

So, if you computer infected by viruses, try to look on those keys registry first.

If you often play with registry, I make sure that you'll need to explore its keys too. Usually, I open Registry Editor and point to my key because Registry Editor will open your last opened key by default. Microsoft provides another way to make it more effective.

The tool called Regjump, and you can find it on Microsoft website.
To use it, download it first, extract it because Microsoft give Regjump in ZIP file, extract it into your own folder but I suggest you to extract it into root folder or C:\Windows folder so you can call it although you currently in different folder with Regjump folder because C:\Windows folder is folder that included in %PATH variable environment value. To configure Windows Environment Variable you can learn on Otak Atik.
In fact, Regjump will help you pointing to certain key in Registry Editor.
Using Regjump is very easy. Regjump is a MS-DOS tool but you can call it through Run menu. OK to begin use it, click Start - Run menu, type regjump in box and then click OK button to test Regjump and if you run for first time, you'll confirm for its Term, just click Agree button and you won't to ask again at next time.
And to using it just type in Run textbox: regjump "registry_path". For example, if you want to open "HKEY_LOCAL_MACHINE\Software\Microsoft\Windows" path, just type in textbox regjump "HKEY_LOCAL_MACHINE\Software\Microsoft\Windows" and then press Enter. And Registry Editor will open with "HKEY_LOCAL_MACHINE\Software\Microsoft\Windows" has opened.

If you're a new Mac user and using Windows as your operating system before maybe you have to adapt for Mac instruments. And that happened to me when I was searching the way to create shortcut for my data files. I've written an article that discusses about substitute between Mac OS X and Windows XP and hopefully, that article may help you to learn Mac OS X.

OK, back to main article, to create new "shortcut" on Mac OS X. Mac OS X calls it 'alias'. Alias has a same function with shortcut on Windows. But, they have a little difference between them. Shortcut on Windows is easy to lost its link to original file such as if you move the original file, shortcut would lost its link to original file (although you'll ask to find the main file when you open the shortcut file that has lost its link but that's pretty annoying for me). If Mac OS X's alias always updates its main file location so, it's doesn't lost its link to its original file even you move the original file except if you delete the original file.
On Windows, to create a shortcut, click the original file, press Ctrl key, click and hold it and then point to your destination folder (you also can choose to the same folder with your original file) and then release the mouse button. The another way is right clicking the file and chooses Create Shortcut menu in context menu, and then you'll get its shortcut in original file's folder.
On Mac OS X, to create a shortcut, press Option + Command key, click the file, and hold it and then pointing to your destination folder and you'll get a new alias in there (you allowed to pointing to original file's folder to create alias in that folder). The another way to create alias, right click the file, and choose Make Alias menu in context menu.
To recognize an original file or a shortcut/alias, usually a shortcut/alias file has a little arrow on its icon.

Registry is very important for Windows series system because entire Windows Configurations are saved inside Registry. So, that's very important to backup it (especially for users who like to 'play' with the registry value).

You can find several ways to backup the registry, but according to my experiments, the easiest way is export the value to single .reg file. To create the registry backup is so easy, just pointing to key which you want backup, right click that key and then click Export menu on context menu. In Save dialog, choose your folder where you want to put the backup file, type your file name and then click Save button. Done!
For example, if you want to backup HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Run key, right click it, click Export menu, give it a file name and click Save button.

If you want to backup entire registry, in Save dialog, click All option inside Export Range frame. Or click My Computer key first, right click it, choose Export menu and next steps are same as above steps.
