On being a ‘Tweet’otaler

YES, I belong to this sensible group of people who have turned away from Twitter. Of-course, at this statement many of my Twitter loving readers would object and wag their fingers  . . . but I feel Twitter is nothing more than boring frustrating account of people’s day-to-day life, expressed that too in one liners for it has a character limit. Twitter not only limit you to post some trivial bullshit but mandates you and as a proof to this statement tweets like the ones below are often seen 🙂

“I went for a drive at 2:30 AM” !   ,

“Dosa tastes best with chutney only”.

I have only one advice for people with such tweets “Get a life ” and spare others as well because seriously nobody cares about it. I mean how can anyone express his feelings about anything within 140 letters and still leave an impact on the reader. Let me make it clear that I do not hate those who use twitter. Most people use Twitter casually since it is the next iteration of Facebook or Orkut . Terms like ‘scraps’ transformed to ‘tweets’ and ‘friends’ to ‘followers’. Log-in to either of these websites  and you see loads of “tweets” transformed to ==>  “Whats on your mind?”  … being updated every 15 minutes, where even household chores becomes your “Status message” !!

I don’t want to write on all the drawbacks of Twitter and sound like Michael Moore (Fahrenheit 9/11) here but one thing is clear, Twitter will neither be missed nor it would replace blogs .

Snow Leopard-Bug in

Apple released Snow Leopard (10.6) with lot of refinements  and additional features to existing Applications. But as the saying goes in the software ecosystem “Lot of code means lot of bugs” and Apple did justify this by releasing  mega-patch to cover vulnerabilities affecting the Mac OS X. The has been one of my favorite and heavily used application and hence hidden bugs surface more often. The previous bug being on Tiger 10.4, legacy continues unfortunately on Snow leopard as well.

Now here is a scenario, Navigate to /Applications/Utilities and launch Enter sudo su –  as shown in the picture. It would ask you for a password.


Now without entering the password, Quit the Terminal

and boom ! … goes kaput, doesn’t even show the prompt and becomes useless. The only option to rectify this  is to restart the machine. Now how is that for a bug 🙂

Snow leopard-flavour of the season


The cat family moves on, from 10.0 Cheetah to the latest 10.6 Snow Leopard being its seventh major release. Wonder if the next OS X would be named as Lion as that is the only one left in the cat family. Well… got to wait and watch. I have been using  Snow Leopard  for few days now and must say that there has been lot of refinements especially the Exchange support with auto discovery feature of Microsoft Exchange Server. The hype surrounded the OS X with Apple giving developer seeds only to people or companies with developer accounts, stopping people from disclosing information to public under Non-Disclosure Agreement (NDA). Just days before its release the security world on the net went abuzz with rumors that Apple has quietly added a new  feature to scan software downloads for malware. Hmm… contradicting to what they actually advertise . Later it was found that Snow Leopard is protecting Mac users against certain file types. The plist file is located in the below path


Even though Snow Leopard is basically a glorified service pack of the current Leopard 10.5 it has lot more to offer.One can go through the technical specification in this link Finally coming to the most obvious question … Will Snow Leopard be a better OS than Windows 7? Only time would tell.

(Mac OS X 10.4)Bug in

I had a long overdue for a post in this category as hectic work at the office kept me at bay. But there was an interesting find that had to be posted, for i strongly feel that solution for this trivial yet hard to identify bug would help all those users who are still on Tiger 10.4.X and here is the flash back …

Couple of months ago I was working on some shell scripts and was trying to get a PID of Console application running on Tiger 10.4.11 with the below command and to my amazement i didn’t get the process id at all even though was running !! After some struggle it came to behavior that was illogical, it never worked for the very first time i opened the terminal and then type the below command. Try executing different commands and then the below command would work fine. I tried many other options thinking some of my commands were wrong but with little success and neither did Google search helped. The same command was working like a charm on Leopard 10.5
PID=`ps -ax -o "pid" -o "command" | grep -i "/Applications/Utilities/" | grep -v grep | awk '{print $1}'`
echo $PID

Days went by and was still not able to figure out why the above problem was happening. But then i discovered a strange thing when i expanded the terminal . Check out the picture below,

Weird Space

If you open a new terminal, window resolution will be by default 80×24. That is it has 80 columns. so when you type the above ps -ax command, the output of this command will stretch to columns more than 80. So i probably think there is bug in on Tiger. If you expand the terminal for a bigger view after the ps -ax command, most of the output will be truncated and hence i wasn’t getting the PID. Phew … that’s a weird find but how about the fix?

PID=`ps -ax -w -w -o "pid" -o "command" | grep -i "/Applications/Utilities/" | grep -v grep | awk '{print $1}'`
echo $PID

see those “-w ” twice .. well if you man ps command you will know it. After this small tweak in the script everything works fine !

man ps

Metadata of Images

Have you posted an Image or 2 on the Internet ? Of course … Who doesn’t nowadays. Everyone is hooked to at least  one social networking site. Be it the popular Orkut and FaceBook  or  Web-blogs all have images of all types.

You might ask me … So What ?? Well i would be more than happy to answer that.  Did you know that when you take a photo with a digital camera, a truck load of background information is embedded into the file called Exchangeable image file format (EXIF metadata, including when the photo was taken, the make and model of the digital camera, the exposure, shutter speed, lens focal length, whether the flash fired, and some other interesting tidbits. Sure, if you have nothing to hide about ,then you should not be worried but still why give away more information ?

Digital cameras save JPEG (.jpg) files with EXIF  data and  Camera settings and scene information are recorded by the camera into the image file. Believe it or not, Preview application on Mac OS X can display all this EXIF metadata — you just have to know where to look.To see the EXIF data for the current image, just press Command-I, then click on the Details tab, and if you scroll down a bit, you’ll see a header for EXIF Properties, along with the full scoop on your image.
check the below image that i had taken for its meta data.

This is on Leopard 10.5



This is on Tiger 10.4.10


OK, all said and done … but how can i remove or clean Up the image you want to upload ? No need to get paranoid, you got lots of applications on Windows but i am surprised to see that there not even one good application on Mac . The closest that i could been in getting a tool was SnapCleaner 1.3 and that too its not free !  This application didn’t work for me and hence i wouldn’t recommend it at all. For Windows you can use this small application called JPEG & PNG Stripper
You can also use this website which is an online EXIF data extractor that provides information.

Next time you have personal photos and want to upload it on to the web especially social networking sites … TAKE CARE !

If you want in depth understanding about Sudden Motion Sensor visit

There are many applications which make use of SMS ad protect your Mac Book.
