Nice cons about Ubuntu 9.10

ZDNet told some interesting but real cons about Ubuntu 9.10 in the comparison with Windows 7. To install Ubuntu 9.10, you need to find the installer CD which is not available like Windows 7. You need to download the ISO of Ubuntu then burn it to CD then install. But for Windows 7, just buy it and install it. So getting Ubuntu installer CD is a problem for the normal user. To install Windows 7, one may need to buy a new PC with good hardware but in case of Ubuntu 9.10, all hardwares in the market don't work perfectly coz the manufacturers don't provide the driver of their products.Everybody knows the problem of codecs and the proprietary DRM for the media formats which is a little bit problem for the normal user.

Google Transliteration

Its very difficult to type complex script without the help of a software. We always use third party software to write complex script. But during travel and if we don't our netbook, the its impossible to write our language. Google India Labs developed a transliteration system. Its very easy to use it. You can write your language directly in the text box. Currently it is supported for Arabic, Bengali, Gujarati, Hindi, Kannada, Malayalam, Marathi, Nepali, Persian, Punjabi, Tamil, Telugu and Urdu. Go to http://code.google.com/p/t13n/ to know how to use it. 

Python threading: An experience as newbie

I was trying to use threading in my python program and as I am new in python I need to learn the Threading. I was googling for a quick example of python threading and I found the following program from here.

import threading
import datetime

class ThreadClass(threading.Thread):
    def run(self):
        now = datetime.datetime.now()
        print "%s says Hello World at time: %s" %(self.getName(), now)
       
for i in range(2):
    t = ThreadClass()
    t.start()

When I run it, its give the following error:

Traceback (most recent call last):
  File "threading.py", line 1, in
    import threading
  File "/home/murtoza/pyro/threading.py", line 4, in
    class ThreadClass(threading.Thread):
AttributeError: 'module' object has no attribute 'Thread'

I just copy the code from the net, and it should run perfectly but why its not running!!! Whats the problem in the code? I had no idea. I googled by the keyword “AttributeError: 'module' object has no attribute 'Thread'” and found this. Its the same error, same OS. And I got the solution in the second page.

What I did? I coped the code from net, made a file named threading.py and pasted the code. Then run it by $ python threading.py command. The compiler got confused. The first line of the code is import threading . Which treading file compiler should import. The file I made or the file system has? Both file's name is threading.py . The priority is the file I made, and there is no Thread inside my file. Actually this file is not a library. So I just rename my file as threadTest.py and its work perfectly.

Google Docs previews in Gmail

Its great coz now I can see Google documents, spreadsheets, or presentations right in my Gmail inbox. For this I needed to enable a new Gmail Labs feature, Google Docs previews, that is released today.

Its a great feature for those who use Google Doc and share with friends, office mate, and others. Why need this feature as we can see the document in the new tab by clicking the shared link? My question, why i need to open another tab to see whats inside the doc? As its a Google product, why i can't see inside the Gmail? Remember the lab user, when Gmail Lab team made a great lab feature to view the YouTube videos, Yelp reviews, and Picasa and Flickr albums inside the Gmail. It was a great feature for me also its help me to save my time. This feature will also save my time a lot.

For more information on Google Docs previews in Gmail, check the Gmail blog post .

Got the wrong Bob?

Got the wrong Bob? is a new lab feature of Gmail. As gmail made us lazy, so we don't wanna type the full email address. We just type the first few char of the email address or the name. So there is a great chance of sending the email to a wrong person. I ever sent my mobile contact backup to a public group in place of my back email address. My colleague sent an informal email to our boss in place of me mistakenly coz the first two char of my name and my boss's name is same.

These things happen as we are becoming lazy coz of gmail's contact suggestion and now gmail is helping us to prevent this type of mistake. Got the wrong Bob? is a lab feature that can help us so that we can't do these type of mistake.

But to prevent sending email to wrong place, we need to be careful.

I got Google Wave

I got an invitation of Google Wave from one of my friend. He got it few months ago. I was really happy to get that invitation. Its took few days to get the invitation after my friend invited me. When he invited me, they said "Invitations will not be sent immediately. We have a lot of stamps to lick."

I added the Sudoku Extension and played together with friends. Its really enjoyable to play like that.

I didn't get any option to send invitation, so I can't send any invitation. There are many of my friends are asking for the invitation now. I hope googlewave will give me the option to send invitation soon.
