Filed under: Bash,linux — Tags: , , , , — admin @ 2:32 pm
Normal Redirect:

command > filename        Redirect command output to a file
command >> filename       APPEND into a file
command < filename        Type a text file and pass the text to command
commandA  |  commandB     Pipe the output from commandA into commandB
commandA &  commandB      Run commandA and then run commandB
commandA && commandB      Run commandA, if it succeeds then run commandB
commandA || commandB      Run commandA, if it fails then run commandB

Numeric handles:

STDIN  = 0  Keyboard input
STDOUT = 1  Text output
STDERR = 2  Error text output

command 2> filename       Redirect any error message into a file
command 2>> filename      Append any error message into a file
command > file 2>&1       Redirect errors and output to one file
command > file 2<&1       Redirect output and errors to one file
command > fileA 2> fileB  Redirect output and errors to separate files
command 2>&1 >filename    This will fail!

Redirect to /dev/null (hide errors):

command 2> /dev/null            Redirect error messages to /dev/null
command >/dev/null 2>&1         Redirect error and output to /dev/null
command >filename 2> /dev/null  Redirect output to file but suppress error

Thanks to Android, HTC sales in May reached $1.42 billion, more than double last year’s total

Filed under: General — Tags: , , , , , — admin @ 3:52 pm

HTC has doubled its sales in 1 year by selling android phones, it shows how smart the managers of HTC are.
HTC originally had a partnership with Microsoft to implement WP7 on its hardware, when HTC implemented Android, Microsoft sued HTC due breaking the agreement.
Finally HTC insisted on using Android and agreed to pay $5 fine to Microsoft per Android device sold. Microsoft has received millions of dollar from HTC so far due to this fine.
In fact Microsoft has made more revenue from Android compared to its own mobile solutions ! Microsoft should be a big fan of Android now.
Current position of HTC puts Nokia partnership with Microsoft in question , when Nokia chose WP7 for its smartphones , Google made an announcement calling Nokia’s decision a big mistake.
Is Nokia wise enough to pay millions dollars of fine to Microsoft like HTC did and implement Android ? We should wait and see 🙂
All of this are very bad news for Apple. no company likes to see its competitors having 100% revenue increase in just one year.
I can see the comments of disappointed Apple Lovers all over the web now , begging Apple to do something , like this one :

Please Apple put some effort in your next phone. Otherwise i have to buy one of these HTC products too.

Its time to say goodbye to iOS and iPhone and switch to Android 🙂

No iPhone 5 for Apple lovers , Apple stock price fall

Filed under: General — Tags: , , , , , , — admin @ 10:35 pm

Regardless of announcing some new updates including iCloud, iOS 5 and Mac OS X Lion in Apple’s WWDC 2011, The Apple stock price fell dramatically this afternoon losing 4.57% of its value.
Seems the investors already know that apple has fell behind the competition and has nothing new to offer. I expect more price fall and a gap between today’s closing price and tomorrow’s opening price for AAPL.

It is very clear that market is not satisfied and will continue to react to absence of announcement of an iPhone 5.
Many apple lovers were waiting for iPhone 5 and with no clear release date, a large portion will decide to not to wait anymore and buy an available phone.
It makes a brilliant opportunity for android device makers like Samsung, HTC, LG and Motorola to saturate the market with their own products and cut the Apple’s market share even faster.
Some rumors suggest that iPhone 5 will be released with iOS 5 this fall, but even if it’s true, it is a very bad move for Apple. disappointing many customers.
It is time to say goodbye to iPhone and switch to Android devices 🙂
