Why does Google want to diversify from search?

That's a good question. I doubt if Google can monetize the Chrome OS but I believe in the long term it gives access to the desktop should Microsoft tightly integrate Bing into their OS. Their aim would be for the ad-revenues obtained from accessing Google services. The move to diversify away from the core business is quite risky and might not go down well with the investors.

Another point to note is timing of their announcement. I can think of two reasons why this is significant:

• With Windows 7 close to a release, I believe the folks at Mountain View are sending out a message to hardware vendors and OEMs to reconsider an alliance with Microsoft.
• Diverting attention away from Bing, as it has been receiving rave reviews.

Where does Chrome OS fit?

The segment where Chrome OS would have maximum impact is ARM-powered netbooks. On the other hand, it would have the least penetration on the enterprise side.

Who is likely to migrate to Chrome OS?

• Netbook buyers towards end of 2010
• Google fanboys. Oh boy!!! There are a lot of them
• People who don't care about the UI of an OS. All they love using is facebook or twitter. These people wouldn't even care for the browser they use (and most sadly use IE6). They would be attracted to the low cost of the netbooks and might migrate.

Who's not going to migrate to Chrome OS?

• Enterprises.
• People not comfortable with having their data on the cloud.
• High-end users. These folks usually use Photoshop, Flash, Matlab etc.
• Folks from countries where an internet connection is still not very usable.

My time for a prediction

Almost everyone's made one...why should I be left behind?

Chrome OS validates the Linux kernel hackers efforts of porting the OS to as many architectures as possible. Probably 2011 might be the so far elusive year of "The Linux Desktop".

Chrome OS is going to have a limited impact in the desktop market too. Why live in the browser when Moore's law is at work? It might gain a 10% market share in 5 years and around 40% in the netbook market for the same period. I am projecting a high number in the netbook market because hardware vendors might release lots of ARM powered netbooks and Windows stands no chance in this segment.

So is Microsoft going to keep quite? Probably not, but they are definitely not going to panic. They have a large userbase and can adopt the "Wait and Watch" policy. If they believe Chrome OS will be a hit, they'll have a similar offering.

Surprisingly, not many people have talked about how Chrome OS affects either Apple or the Linux Desktop community.

I think there's something cooking in Apple. Lots of rumours are indicating they are probably designing a chip for a netbook or an MID? We'll have to wait for an announcement from Apple. The Linux community on the other hand wouldn't be adversely affected because Chrome OS gets added to the zillions of distributions and the users are most likely to be displaced from a few distros to Chrome. So it's bad news for some distros but good news for the Linux Desktop community as a whole.

Google has open-sourced the effort like Android but it has to been seen how transparent the process of making and deploying apps is. The community's reaction and marketing the concept to hardware vendors will be the key to Chrome OS' success.

Has to be seen if Windows ecosystem or Google's brand win eventually!

What is Google Safe Browsing

It is an API that enables applications to check URLs against Google's constantly updated blacklists of suspected phishing and malware pages. For more check out http://code.google.com/apis/safebrowsing/

Why use Google Safe Browsing?

Nowadays everyone is bombarded by loads of spam soliciting people to click on an innocent looking ;-) link. If some dumb user falls for the trick then his life would become miserable from that moment. As elders say Prevention is better than cure, so be careful before you click these links.

Google Safe Browsing is a step towards preventing the user from making such dastardly mistakes. Google, one of the largest and popular online search engine has released the database of suspected malware and phishing blacklisted sites.

Google is one of the most active partners of StopBadware and AntiPhishing and hence you have access to almost all the badware site urls.

Why Django?

Django is one of the coolest Python web frameworks around. I have been associated with Django for quite some time now and wanted to contribute my bit to the community.

• For Django users, I have created a form field called Safe_URLField that checks against the database and raises an error if the url is found in it.

from django import newforms as forms
from safe_browsing.forms import Safe_URLField

class SomeForm(forms.Form):
    url_descr = forms.CharField(max_length=50)
    url_field = Safe_URLField()

>>> data = {"url_descr": "Crap Site","url_field":u"www.fxmp3.com"}
>>> f = SomeForm(data)
>>> f.is_valid()
False
>>> f.errors
{'url_field': [u'For Malware Detection:This page appears to contain malicious code...']}
>>>
>>> data2 = {"url_descr":"Excellent Site","url_field":u"http://thejaswi.info"}
>>> g = SomeForm(data2)
>>> g.is_valid()
True
>>> g.errors
{}

Who can use this service?

• Sites where there is input of urls whose credentials might sometimes be suspect, thanks to spammers.(A classic example would be DjangoSites).
• Folks who download lots of software and music from untrusted sources.

For a demo, you can check out the service here.
