pavan on PCQ forums: Can you please share any code on Excel applications
like reading data from or writing data to an Excel file?
Sudipto on PCQ forums: Microsoft has released the Excel Binary File Format
(.xls) Structure Specification, which can be used to develop code to manipulate
XLS files. This specification is available from MSDN website
(http://msdn.microsoft.com/en-us/library/cc313154.aspx)
NSK8700 on PCQ forums: What would a mobile hacker achieve if he gets
access to the IMEI Number of other person's mobile phone. Who is recording IMEI
Numbers [#09780797807 or Voice#097 80697806]. Do you know who has called
Voice#09780697806, know about the identity of this person? A message was
received from "Safe Mob" providing the procedure to generate the IMEI# and
asking the IMEI# to be sent to #09780797807 ? Please provide reference to some
geek mobile tech forums/platforms.
Prasanth on PCQ Forums: IMEI numbers identify the equipment that you are
using in this case - your cellphone, and is used to block your cellphone in case
you report it stolen for example, as it's unique to your phone. Of course, since
IMEI number uniquely identifies your cellphone, it should be treated just like
any other 'identification code', which you wouldn't want to pass on to someone
un-trustworthy.
Try Esato Forums (http://www .esato.com/board/), if you are interested in
pursuing mobile phone stuff further.
PCQuest: An IMEI number is something like the Mac address of your LAN
card which is unique and is used to identify and track a particular phone. But
thankfully the mobile network doesn't rely on IMEI number to connect to a phone.
Rather a Customer Identification Number which is embedded into the SIM card is
used to register a number into the mobile network . Hence only if someone can
get and copy your SIM's CID number then only he can intercept/spoof your phone
number. This technique is called SIM cloning. but again, thankfully, this number
is encrypted into a SIM card and is stored in a area of the SIM card called WORM
(Write once read many times) type. So the only way to clone a SIM is to first
crack the encryption of a SIM card and get the CID number, then get a blank SIM
(without any CID number ), then write the cracked CID number to it. The process
is very time consuming and is only possible with old SIM cards.
Most SIM cards that are shipped after June 2005 in India have a better
encryption and are near impossible to crack. For some more info on Mobile

a.m.r on PCQ forums:What will be the future of MySQL after the Sun
takeover by Oracle? Will it be stopped gradually, will Oracle use it, to explore
a new market segment and will it be downgraded as a free demo / test /
educational product.
Rakesh on PCQ forums: Amongst the developer community the most favored
database happens to be MySQL. And with the takeover of Sun by Oracle, the fear
looms about MySQL's future. I think Oracle will not hamper any of the Sun
Microsystem's entities. It will try to gain benefits out of each one of them.
Though Oracle's database remains to be one of its mainstream proprietary
products, MySQL being open source and also being supported by Oracle after the
likely takeover would be a business contradiction. The fear of MySQL being
ousted or no support being provided after the takeover, shouldn't happen, but
time will tell what's the Oracle's take going to be now.
Prasanth on PCQ forums: Oracle has bought MySQL to access its huge
customers base, so it is unlikely to pull the plug on MySQL. That will be like
killing the golden goose (which they paid a lot for!). Of course, you might have
a scenario where new features may get slowed down etc. But, then there are
plenty of amazing DB platforms that are catching up.
