Non-touch screen technology

Wait a minute, isn't touch screen is the most hip thing nowadays? If you don't have a touch screen device, you seems like out of touch from technology. Well, in this case it is you don't need to touch the screen, what you need is finger gesture. Similar to X-Box kinect, but you don't need to be jumping up and down, squat and wave like a mad man or woman to control the game. Watch the video from Leap Motion:



The second video seems like same as first video, jump to 0:52 to see the fingers being detect and play Angry Birds with a pair of chopstick!


Btw, touch screen can hurt fingers or skin if you use it too much and too often, especially playing games. :)

Facebook Free Money?

Facebook is giving me free money. No bluffing, Facebook is really giving me free money.

I got this email from Facebook last night:


Apparently it is because this blog's Facebook Page has reached 300 Likes last week. Facebook is offering me US$50, wow, that is about RM150. Not bad at all.

US$50 for Facebook is much much smaller than a peanut. With market capital at 70.62B (May 24, 2012), the money Facebook gave me is about 0.0000000007% from it's market capital.
Anyway, how often someone that is not working for Facebook getting money from Facebook? :P

Alright, I am going to use the free money to run ads on Facebook!

Mini-Android Computer for US$74 only!

 How much it cost you the last time you bought your last computer or laptop? At least a few hundred dolars (more than RM1k) right? Would you want to buy a secondary computer or laptop for your family that just want to surf net and email that cost as much as your first computer? I don't.
How about a mini computer that cost about US$74? Of course this is come without screen/monitor.

Powered by a 1GHz Cortex-A8 ARM CPU, 512MB of memory and 4GB storage, this guy can run ICS (Android 4.0)! With WiFi b/g, expandable storage up to 32GB, a micro USB port, you can turn this this into your secondary PC just for net surf and email.
The website also claimed that the HDMI ports supports 1080p and 2160p. Come with pre-installed apps such as Youku, Tudou, QQ, Youtube, Twitter, AngryBird, Office, Gmail, Browser and Skype. However there are 4 question marks after Skype, I wonder that is some sort of fine print. You know what I mean.

It is free shipping via China Post Air Mail to most of the country world wide. I think it is a great deal for a secondary PC. And it is sold out at the moment, you can order now, but you have to wait for the supply to come in to the seller.

Go to this website to look for more detail and fine print :P

How to Unlock Samsung Galaxy Tab 8.9

 XDA is always full of wonderful people. This time its member yassine22 shared the method on unlocking Samsung Galaxy Tab 8.9.

pix source: samsung.com

Step 1: Root your tab
[ why root the tablet: unlocking the tablet requires access to hidden system files in the root. The root is not normally made accessible to the standard users]

• From the web, search a Root package (easy to find on the web, just google ‘galaxy’ ‘root zip’ you’ll get a small zip file, it may be root.zip, root2.zip, doesn’t matter)
• Download the root zip file.
• Copy it to your tab and remember exactly the folder where you paste it.
• Turn off you tab.
• Press simultaneously the volume (-) and power buttons and continue pressing until you got a system screen with two items menu (download, and …).
• Press the volume (-) again to navigate through the two items of the menu, select upgrade.
• In the top of the screen, you’ll get a list menu with 4 items. Scroll to item “install from SDCard” (use volume (-) and (-) to scroll).
• Press power button to select.
• You’ll have to select the root zip folder, navigate through the folder structure using volume (-) (+) buttons.
• Press the power button to execute the zip file.
• Rooting operation will start, you’ll see many progress messages, just wait until the whole process finishes, it takes few seconds.
• Navigate back the menu item “reboot the tab”, press power button.

[ Your tablet will reboot now, you will notice no change, but the change is there, your tablet is now rooted]

Step 2: Preparing to unlock

• From the market, install the free app “super user”.
• Open the newly created shortcut “super user” and validate any message you get, close if necessary, [the SuperUser is an app that will work in the background and grant permissions –when necessary- to other applications to access root. Without it, rooting a tab is meaningless].
• From the market, install “root manager” [root manager is now your file manager that can go deep through the folder structure and access root folders].
• Launch the “root manager”, the first time you do that, you’ll be prompted to allow “Super User” to grant permissions to “root manager”, allow that.
• Take some time to make yourself familiar with “root manager”, it’s a very simple but powerful file manager.
• Now go back to serious work, locate the folder \efs at the root, [efs folder is very important, it holds all the information to validate your tablet to the GSM/3G operator, it validates the authenticity of your IMEI].
• Just make a copy of the whole folder and save it in a safe place – your PC or a memory stick-. We’ll be back later to this copy, continue now on the tab.
• Open \efs folder, locate the file nv_data.bin.
• Make a copy of nv_data.bin in the same folder \efs and rename the file eg: ORIGINAL_nv_data.bin
• Delete all the files in the \efs folder except nv.log. Don’t delete the sub folders ( you should normally have the following sub folders .files, imei, gyro….). 
• Now leave the tablet powered on (don’t turn off) and move to your PC to continue job,

Step 3: Molding the nv_data.bin file

• In the copy of the \efs folder that you previously made, locate the original file nv_data.bin.
• Make a copy of this file somewhere in your PC. That’s the copy you will be working on.
• Edit nv_data.bin with HexEdit.[ If you are not familiar with depths of binary files, don’t be daunted by the array of codes and bytes].
• Locate the byte 0x181469, it should read 01 value, just edit it to 00 value, do nothing more, just save and exit.
• Now you have created the molded copy of nv_data.bin.
• You need to move this copy of nv_data.bin onto your tablet, either using a memory stick or by USB cable. Paste the file in the \efs folder.

Step 4: tweaking the molded nv_data.bin file

• Now that you pasted the molded nv_data.bin to \efs folder, it needs some minor adjustments before being used.
• In the “root manager”, press and hold on the newly pasted nv_data.bin.
• You’ll get a menu, select properties.
• In the properties box, check all the 9 options (read, write, execute), leave the others.
• Save and exit root manager.
• Go the market and install the free app “terminal emulator”.
• Launch the terminal emulator, accept any message for super user permission.
• In the terminal emulator, execute the following commands [press enter after each line of command]:
• su
• chown 1001:radio \efs\nv_dat.bin
• reboot
• It’s done, your tablet will reboot unlocked.

Verification to make sure everything is OK

• Go to settings, about device, status. Make sure you have a valid IMEI number, the one you have printed on the back of your tablet, not the fake one: 00004**********
• Insert a valid SIM module, you’ll be promted to enter PIN code if configured so.
• Enter PIN code.
• Enter the APN provided by your operator (necessary to access internet 3G).

Warning: unlock/root your Samsung Galaxy Tab may void the warranty as well as brick the device, do it at your own risk.
