When you are the move all the time you might not get access to your PCs everywhere you go and there are time with limitten internet access to your laptop (if you have one). Some day you might need to get access to your IM (Instant Messaging) account to talk to your friend or someone of your interest.
Now, this limitation has been overcame by Meebo.
A few days ago, my internet connection was suddenly not working. It was out of the blue and trying to figure out what went wrong, I reset modem, router, restart computer, etc. None of them work.
The head start of the solution was found to be Zone Alarm Firewall problem, and it should be either disabled or set internet zone to medium to get internet connection working.
After a few research, I found a link which took me to Zone Alarm support site. It stated that
Microsoft Update KB951748 is known to cause loss of internet access for ZoneAlarm users on Windows XP/2000. Windows Vista users are not affected.
A further research found that windows update “KB951978″ also give the same problem.
If you are one of the victim then this link “http://download.zonealarm.com/bin/free/pressReleases/2008/LossOfInternetAccessIssue.html” will solve your problem.
Stay safe :)

Ey! do not panic when your Windows XP cannot format your hard disk while you are formatting your computer. This article will help you to over come the problem.
At the time you would get the message similar to this
“this partition cannot be deleted because the maximum disk space already used“
Well the following line are what I have observed and it happen to me.
If you go ahead and delete other partitions just to accommodate this Windows formatting requirement, you will lost the data on those partition.
At the time it happen to me, I couldn’t possibly see any other way to work around it while I am in the “giant” blue screen. The only way to overcome this is to boot the computer from one of the Linux Live CD (I use Ubuntu) and format the partition that I need.
Linux formating tools doesn’t demand for spare disk space or complain about maximum disk space has been used. More than that, it could format your disk partition to serveral different orders/formats such as Primary, Logical, FAT, NTSF, etc.
When you are done, just reboot your PC and go back to your Windows installation, when you get to the step where the list of all disk partitions, do not delete any of those. Just selected the one you need to install Windows and do a full format in the next step. Note that if you do a quick format you might possibly have problem installing windows on that partition
We have to Thanks to the Live CD :)
For those who use dual Operating Systems (eg. Linux, Windows) you might find this article useful when you come to the time where you need to re-format your Windows Operating System.
In my case, my computer has dual boot with Ubuntu and Windows XP and today I need to format my Windows XP but I don’t want lose my entire Ubuntu. Now it’s different from in the old day experience, I usually lost every partitions after formatting Windows and I wasn’t aware that GRUB can be reinstall to get the boot menu back.
There are serveral ways AND there’s an easy way to recover this problem. Just though I’d post it here for my future reference and hoping it might help other as well.
Assumed that you have Linux CD handy. I use Ubuntu Live CD (Ubuntu 8.04 LTS Desktop Edition) at the time writing this article.
sudo grub
find /boot/grub/stage1
root (hd0,0)
setup (hd0)
quit
Autorun is a mechanism to run the program automatically without any user interactions. It usually used in media such as CD, DVD, USB Disk etc. Whenever a media is successfully attached or inserted to the PC, a tartget program will be executed automatically. Most of you might be familiar with installation media, it usually bring up the welcome screen or the installation wizard as soon as you insert CD or DVD into the drive.
Basically Autorun is there to enable the conenience for user and give more controle to software vendor to bring up what want you to see when you instert/plug the media into your PC.
To find out more about what is Autorun, go to http://en.wikipedia.org/wiki/Autorun
Now let’s look at it a bit closer. This feature could expose to a security threat where hacker or virus writer could take advantage of this to execute their file without user even know about it.
Autorun is enabled by default in Microsoft Windows and there’s no straight forward way to disable it (such as icon in control panel). However this is not the end of the story, it can be disable by editing the windows registry yourself or use a tool like TweakUI PowerToy from Microsoft
Disable autorun by editing registry:
HKEY_LOCAL_MACHINESYSTEMCurrentControlSetServicesCdromDisable autorun by using TweakUI PowerToy:
Now you can have a peace of mind when insert/plug any media to your PC.
Before I start my article, please note my system at the time I had problem
Today, I tried to setup Ubuntu Server 8.04 on vmware server. I ‘ve got all the basic setup and virtual machine was created on the NFTS drive. For some reason I couldn’t get vmware server to start my newly created virtual machine.
First stope I did was close and reopen VMware Server and tro to start the virtual machine a few time but it didn’t help.
After a few click research, I’ve found the solution which cause by the way VMWare Server is using NTFS.
Thanks to NTFS-3G for the work-around (http://www.ntfs-3g.org/support.html#vmware)
Workaround:
Set “mainMem.useNamedFile=FALSE” in the .vmx file. It will disable paging files and VMware will work fine, often with much better performance.
When you want to use a new version from the distro doesn’t mean you have to get rid of the existing version of you system and reinstall a fresh new one and you will have to run through installing all required packages/applications for your work. Simply just take the advantage of the upgrade facilities provided by Ubuntu distro.
At the time of writing, I am upgrading Ubuntu Server from version 7.04 to 7.10
First make sure, current system is most up to date.
Perform update with the following commands.
If you feel that there’s more updates to be done, just repeat the 3 steps until no more update availalbe.
You system is now ready to upgrade to the next version. Perform upgrade with the following commands.
Enjoy :)
I have been getting problem with mounting my ntfs disk partition after upgrading my Ubuntu from verstion 7 to 8.
I though I could be problem with the upgrade that stuff things up and something could went wrong while upgrading.
After a few research, I’ve found it’s likely not because of the upgrade. The problem could possibly be: the disk partition hasn’t been completely released from window processes.
What I did was, force mount with the following command:
manet@netubuntu:/$ sudo mount -t ntfs-3g /dev/sda1 /media/sda1 -o force
manet@netubuntu:/$ sudo mount -t ntfs-3g /dev/sdb1 /media/FIXED250G -o force
They are mounted successfully with the following warning message
$LogFile indicates unclean shutdown (0, 0)
WARNING: Forced mount, reset $LogFile.
which can be ignored, but again this is done at your own risk.
