Don't get caught up in all the rooting hype. I am glad I didn't root my tablet and although I like the stuff on my rooted phone, it is not stable and if I could go back to the stock ROM I would. It is just so easy to get caught up with it reading the articles and watching the videos on youtube.  Just look at that red sign you got in your post. Those will keep you out of trouble and happier!

If your want to play root, do it in an emulator to see what you're unable to on the stock device. I'm pondering why sudo (or it's mechanism to allow temporary root functionality) can't be added/enabled on this open source OS. I'm sure there are certain Android applications that are purchased from the marketplace that need root functionality to install. It's hard to believe this functionality isn't available and forces users to burn a new OS image and voiding the warranty. Why doesn't device manufactures just allow root by default and provide a factory reset option that restores the device like it was when you took it out of the box. (doing a backup first would be wise)

At this point I'm not planning on rooting my Galaxy Tab 2 10.1 device. I find it more of a challenge to create a usable Linux terminal environment and still keep the device a virgin. I'm having fun finding out what the SGT2 can offer to scripting language environments like Python and SB. I think ScriptBasic has a fair chance at people taking the language seriously and using it to glue (customize) their digital world.

Root Access - SGT2

Root is similar to Apple Iphone’s Jailbreak. Thus Jailbreak gives the user the ability to change theme, download apps from 3rd party app stores – it still doesn’t give you that amount of power that you’ve achieve when rooting your device.
As i’ve said in the previous article – this is at your own risk!



This is for the Samsung Galaxy Tab! – In order to achieve root on this device, you must first synch it with kies, then disconnect it, then enable USB debugging mode and the launch an homebrewed program called “SuperOneClick” – with that press “ROOT” and you’re rooted! However you’ve still doesn’t have any Custom Kernel or recovery system installed at the moment, this can be done by using the software called “ODIN”.

As you can see – the Samsung device is A LOT easier to Root than the HTC device. This generally applies to all HTC’s and Samsung Devices.

1)      Install Samsung Kies – this is used for installing the necessary drivers that we are going to use for the Samsung Galaxy Tab.

2)      Synchronize your Tablet with Kies, just once would be enough to install the drivers. Disconnect the Tablet. Please ensure that you’ve doesn’t use any other launcher other than the default Touchwizz launcher! Many have reported that the Tablet won’t synchronize, but that’s just due to Samsung that have made the software capable of only detecting the device when running the default launcher/home replacement.

“It is important to install the drivers correctly in order to have any communication with the device. The method for HTC devices is similar as the Samsung devices.”

I'm only developing the SL4A interface for Android 4.x based devices. I'm putting together a procedure on SB Google Code that will be a tutorial of sorts on how to install ScriptBasic (scriba and it's extension modules) on an un-rooted device. Scriba should run on earlier versions of Android regardless.

Here are a few more extension module calls to the t.so (tools) and ux.so (unix specific) functions.

t_xml.sb
declare command XML alias "xmlserialize" lib "/data/data/org.scriptbasic/t.so"

a{"Name"}="John"
a{"Age"}=59

print XML(a),"\n"

t_md5.sb
declare sub MD5 alias "md5fun" lib "/data/data/org.scriptbasic/t.so"

m = MD5("JRS")
print "0 |1 |2 |3 |4 |5 |6 |7 |8 |9 |A |B |C |D |E |F |\n"
for x = 1 to len(m)
  print right("0" & hex(asc(mid(m,x,1))),2) & "|"
next
printnl

ux_fork - I was surprised that Android allowed forking a child process.
declare sub uxfork alias "uxfork" lib "/data/data/org.scriptbasic/ux.so"

pid = uxfork()

IF pid THEN
  PRINT "Created a child process with a PID of ",pid,"\n"
ELSE
  PRINT "This is a child process with the PID of ",pid,"\n"
END IF

LINE INPUT x


I found this SL4A API Help Guide that might be worth having a peek at.

If you’re a challenger to the Android-Apple tag team these IDC standings are simply depressing.

Windows Mobile/Windows Phone has yet to make significant inroads in the worldwide smartphone market, but 2012 should be considered a ramp-up year for Nokia and Microsoft to boost volumes. Until Nokia speeds the cadence of its smartphone releases or more vendors launch their own Windows Phone-powered smartphones, IDC anticipates slow growth for the operating system.

With Android owning more then half the market, scripting phones/tablets (local and remote) may make ScriptBasic more attractive.

Even on my old Acer Aspire 5000, ScriptBasic loads, initializes and process the PRINT script in .006 seconds.

PRINT

About the same time as it takes light to travel one mile in a vacuum.
