It is new year guys. Have you update the copyright year in your WordPress footer? Make sure it is year 2011 and not 2010. 😛
Here is a tip that you can use to automatically update the copyright year. Open up your footer.php theme file, and add this line:
The PHP date(‘Y’); function will display the current year so you don’t have to manually update the copyright year every year. 😉
I was shocked when found out free space in my C drive is only 94MB left. At first I thought it was because of a virus attack so I did run virus scan on my computer but got negative result. So I run disk space analyzer and here is the result.
As you can see, 7GB space has been occupied by Installer folder in my C drive. But is it safe to remove all those files from my system?
When we delete a file, that file will move into Recycle Bin. There, we have options whether to restore it or just empty the Recycle Bin.
I usually empty my Recycle Bin before I shut down my computer. But, it would be more better if evertime when I delete a file, it will completely remove the file from the system and not send into the Recycle Bin. I can choose to use Shift+Delete but there is another better way to do so.
I use my PC mostly for blogging, internet surfing and sometimes pay bills online. I also store sensitive information such as my education grades (this can be sensitive information too :p ) in my PC. Everything that I do and files that I saved are recorded and stored into the hard disk. Even though I have deleted the files and removed “the traces”, they are still exist in my hard disk.
Maybe you have heard about this. When we delete a file, the file that we have deleted is not removed from our hard disk entirely. It is still exist in our hard disk but the operating system doesn’t know where to find it because the first byte of the file has been changed to E5 (a HEX value). The data is still remains on the hard disk unchanged unless when a new data is written on it.
If you have sensitive documents in your PC or you don’t want somebody else found what you did with the PC, you can wipe your traces by using Eraser. Eraser is a powerful tool that can help you to cover up your tracks. This freeware tool will overwrite the file up to 35 times when using Guttmann technique.
By default, Huawei E220 can only support up to 3.6Mbps speed. In Malaysia, 3.6Mbps is the top speed that 3.5G broadband users can get. But the truth is, it is just a fantasy. No one will get that speed.
By default, Huawei E220 only can handles 3.6Mbps connection
I even asked Celcom technician to do speedtest at place. Do you want to know how much speed that he got? Only 1.2Mbps. And the test was done in the morning (at low peak time). And when I asked why he only got 1.2Mbps and not 3.6Mbps or even 2Mbps? Here is what he replied,
“This is because our server can’t support so many users. If there are many users use the Internet at one time, the slowness will happen.”
Duh…what a very frustrating answer. Why don’t you guys (Celcom) use our money to upgrade the server? It is better than hearing our complaints every minutes and seconds.
But this “hack” can make it to 7.2Mbps
Ok, back to the article. How you can “hack” your Huawei E220 USB modem to make it supports up to 7.2Mbps speed? By default, Huawei E220 will only can operates at 3.6Mbps. But by doing this “hack” you can make it to operate at 7.2Mbps.
