Hide File Under Your JPG Image

This is a simple trick to hide your file under the Jpeg image. if you have any confidential file, you able to hide it and save it into pen drive to transfer. Once people steal your file, they have no idea to open. I get know this trick from a blog name Cypherhackz.net

1. Prepare a Jpeg image (Hello.jpg), a document that you need to hide (confidential data. txt), i put both of this file in to a folder call “testing” under C drive
2. 
3. Zip the both file, name it as zip
   
4. Open a Comman prompt , go to the director ( C:/testing/>), type this “copy /b hello.jpg + zip.zip iCalvyn.jpg”
   
5. You will found a new image name iCalvyn. jpg apear, this file contain the both of the image hello. jpg and confidential data. text insite. To open it, open this image iCalvyn. jpg with winzip, you will get the file in site.
6. 
7. Complete, so just send this iCalvyn.jpg to the target audience. Once people obtain this image, he/she does not know what is actually hide behind.

Your PC Performance

Already 2 night i did not sleep well, my company server have some minor issue and unstable since Friday night. I need to dail-in there to monitor on the server status.

My server act weird since friday night, the network are slow, the application on workstation are running slow while transaction. When Saturday morning, everything goes normal and my phone are quite,no call from hotel, i have a peacefully saturday and having my shopping nicely. Nearly evening, the morning shift duty manager have sms me, said that the system are well.

Same as saturday night,very peaceful, no call from my company, and i was having my VCD at home till 2am, since next day are sunday ma, noneed work. Who knows sunday morning 8am get a urgent call, said that the system was down on morning 5am… Damm!!! no life for my sunday. So i have ask them to contact the application support personel and they dail in to indexing (some thing like defrag) the system, it take quite long time to do, normally it took 45Min, but today it took 1 and half hour. After indexing still the same, some more worst, the application cannot run at the workstation, totallay cant load at all.

All the GSA (Guest Service Relation) are panic when the system slow, the guest start to make noice with the slow check in and check out. Some more this moning the system down, they need to do manually. Really pity them lo~ some time get scold by those “non understanding stupid” guest.

I have no choice, support on phone also cant solve the issue, so i need to go there and see what can i do. (Sunday working, no Ove time, no allowance and no…nothing, suck benefit)

How to check your PC performance
Previously when i dail-in on morning, i saw the performance in WINDOWS TASK MANAGER are act weired (my server). The percentage are very high. so how i check the system performance, just right click behind start menu, go to TASK MANAGER

Click on the performance tab, you will see the CPU Usage and PF Usage. Last time when my academic time, one of my teacher told us, the Commit Charge (blue circle)Â must not more then Physical Memory (red circle). Commit charge are the current load program that occupied your RAM and the Physical memory are the memory you have.

Once your Commit Charge more the the Physical Memory, your PC will start slow down. You also able to see which program occupied the RAM by click on processes tab, at the list of program, Mem Usage (blue circle) are the memory occupied by certain program or application

For my case (all the picture are my home PC, not Company server), the Rtvscan.exe current consume 39MB of RAM, if i feel not neccessary there, just click End Process, the program are out. But remember that not all process able to end, once end some needed process, the PC will shut down within 30second. If not mistaken is the svhost.exe

On the other hand, if you see the CPU Usage at performance tab are high, some time near 90% to 100%, your PC are very lack and hang. you also able to check which application use the most at the processes tab, the CPU (Yellow Circle) show the number, normally it will be 99 on those application that consume most CPU Usage

Back to my case
When i arrive company, the indexing is just finish, but the application at workstation are still cant load… slow like hell. At this moment, a light bulb apear in my mind, imediate i shut down all server, plug out the power cable (to ensure no electrict and the memory buffer able to release), same to my switches, close the power, wait for 5 minute and restart everything. That all, everything goes fine after that.

IÂ back to the Performance tab at TASK MANAGER, the CPU usage are still high, suspected are some spyware in there, occupied the CPU Usage. Damm, loss my whole morning there.

Clear IE Password

Few week back, once of my top level management personel face a problem when login webmail, the password always auto apear after she key in the UserName, example i key in “it” and the password automatic apear, that mean the password have been remember in the particular PC.

Do you feel funny??? there was no “remember me” check box for me to tick…Â

After i consult with some IT friend, they teach me to upgrade the IE to ver.7, then the password will be erase. Today, i use this method, but it did’t help much.

How to erase the password? for IE ver6
I have call my senior at KL, he advice me to check at the Internet option, at content tab click on AutoComplete then look for the Clear Password

How to erase the password? for IE ver 7
The way are almost the same, go to Internet Option, directly at General Tab, clickdelete, then at the password column, click delete password

Yup, that the easy way… few week back, the PC are still in IE ver6, so i did not know how to delete the password, i just clear the cache and Internet Temporary File.

Althought when i went to the top management office, there are very presure and anytime will eat bullet, but today, i learn another new thing lo… at least gain some knowledge

Pendrive Portable Applications

~Make full use of your PenDrive~

Do you face before difficulties…
when you are some where else using some one PC and there are no suitable application for you to use?

or when u at some where else using some one PC to surf net and realize that the website you want to visit actually bookmark or Favorites at your own PC!

Few thing i always headache on when i went to friend house, or travels or using other people PC:

1. No Favorites or Bookmark website.
2. No FTP software for me to update my file to my server.
3. No image editing software for me to edit the picture i found.
4. No Email application such as outlook
5. bla bla bla….

And i found a nice software recently called PortableApps, is free portable software that can run in any machine which has USB port.

PortableApps.com provides a truly open platform that works with any hardware you like (USB flash drive, iPod, portable hard drive, etc). It’s open source built around an open format that any hardware vendor or software developer can use.

This software actually give me a lots of convenience, just bought a high capacity PenDrive and you can store a lot of application there. Keep your book mark and all your email there.

With using this software, i can bring my favorites or bookmark and also my email application any where and over my above problem.

PortableApps come with few package, Standard (approximate 90MB), Lite (31MB) , and Base (1MB)

Download either 1 package that suitable you, plug in your PenDrive and install it. For beginner, i suggest you download Base Edition, just a normal package without ant program include, and you are advice to download the application you need atPortableApps Directory

• Standard Edition include: ClamWin Portable (antivirus), Mozilla Firefox – Portable Edition (web browser), Gaim Portable (instant messaging), OpenOffice.org Portable (office suite), Sudoku Portable (puzzle game), Mozilla Sunbird – Portable Edition (calendar/task manager) and Mozilla Thunderbird – Portable Edition (email client) and runs comfortably from a 512MB drive.

• Lite Edition include: Uses AbiWord Portable (word processor) instead of OpenOffice.org Portable and runs comfortably from a 256MB drive.

• Base Edition include: This is a stripped down package with just the PortableApps Menu, PortableApps Backup utility and custom folders, icons and autorun. It’s less than 1MB installed, so it’s a great option for smaller drives.

Standard, Line and Base Edition can be download here

My 2 cent: I like this program because it can store all the favorites URL, and also tun my email application, i found difficulties when i download all the email to my home PC and can’t access on other PC

My Advice: When u started use this PortableApps, remember to constantly backup your date. This is due to may be some happening to your PenDrive such as data loss or PenDrive failure.

Special: Check it out, Mac-on-Stick, this is quite interesting. Run MAC OS on your windows platform.

Msn Hard To Sign-In, How To Fix ItMost of us using Msn Messenger, what version are you prefer? I prefer Live Messenger Well, I encounter this problem

Most of us using Msn Messenger, what version are you prefer? I prefer Live Messenger

Well, I encounter this problem for quite some time, always disconnect while sign in MSN. and some of my friend asking me“Calvyn, what are you doing, in and out… trying to promote your self?”

Recently once of my buddy, Dave Corner who having a solution to prevent this happen. I have try it, it really helps.

If you are having problems with your msn, where you tried repairing and everything is working fine but you still cannot sign in because they say service is not available or prompt you an error code 80004007. Then, it’s means that part of your Messenger client cache may be corrupted.

To attempt to fix, close down Messenger if it’s running, click Start, then Run, and type the following:

%userprofile%\contacts

and click OK.

If nothing appears in the folder, click the Tools menu, then Options, then View tab, click ‘Show hidden files or folders’ and click OK. Once you are able to see the folders, right-click the one that corresponds to your Passport and choose Delete.

Next, click Start, then Run, and type the following:

%userprofile%\Local Settings\Application Data\Microsoft\Windows Live Contacts

Then remove the corresponding folder again in this folder.
Then restart Messenger and try signing in again.

Reminded if you are worry on your data, please do a backup on the file before you delete. This is an ADVICE from IT Engineer.

Clear Windows Login Password

Beginning of this week, me and my “Sifu” (senior colleague) went to a client company for IT support, and my Sifu pass me a laptop, he said if the user forgot the windows login password. Ask me to find solution (my assignment)

Wow, such a deep question here,

Me: Sifu~ totally unable to login windows, how to clear it?

Sifu: Find solution, there has few solution out there, try to googling,

Until today, I found few solution, and still testing it. Here have some action to show, but cant solve my problem yet, becouse this method is do it went you are already in windows. (sad..but not the solution for my assignment )

Click Start -> Run -> type cmd (Open a Command Prompt)

Type C:\> net user

You will see the available user in your PC

To clear that particular user password

Type C:\> net user username password (example like above)

Above picture, i have change iCalvyn password to 11223344

The above method are not apply to what I looking at. This method are useful provided that you already login in to the windows, but for my case, i am not able to login in to windows yet.

Clear Windows Login Password (II)

I have post a simple method that able to clear windows login password month ago. That method are very simple and will be able to find this solution anywhere online.

After read KeshZone.com post about the winternals password cracking method. I still on my way to test out that software. 1 thing I can said is we need tools to crack or break the password and this winternals software are hard to find in the market, you may download at KeshZone.com also

I have a special method which no need any tools to clear the windows password but it take longer time. This method also easy to find when goggling with the right key word.

What you need is just a windows XP installation CD:

1. Insert the Windows XP CD and restart your PC.
2. While the CD is boot, you may see “Press any key to boot from cd”, hit it.
3. Just like normally windows installation and while you at Welcome to Setupscreen, press ENTER to Setup Windows now.
4. Press F8 to accept the Licensing Agreement.
5. Setup screen will appear and this will show “If one of the following Windows XP installations is damaged, Setup can try to repair it” . You need to press Rto begin the Repair process.
6. Let the repair run until it reboot, after reboot will be start Installing Windows.
7. At this stage is the most important part, while the lower left hand side of the screen display Installing Devices progress bar, press SHIFT + F10. This step is the security hole and it will prompt you a command console.
8. At this DOS prompt, type NUSRMGR.CPL and enter. you will gain a graphical access to your User Accounts same as your control panel
9. At this stage, you may change the password you prefer or remove the password
10. If you want to login windows without asking any password, type control userpasswords2 in the command prompt.
11. After made the changes, close the windows, close the command prompt and continue windows repair. After repair done, you will have your new password to login windows, all the setting in there are still remain same.

This method without need to buy any special tools or software, we just use the security loop hole to crack down the password, but the disadvantage are time consuming. This method is workable, I personally tested before.
