    Google bidding for wireless spectrum 

    I am presenting this topic tomorrow at office. Here’s a quick primer of the story behind the news.

    What is so unusual about this news?

    Google is a search company and spectrum is normally bought by Telcos.
    That’s why this news is worth a look.

    So why is google doing this ?

    Google is just expressing an interest in the bid, provided the spectrum sellers impose certain restrictions on the potential bid winners.
    Spectrum auction is few months away and the officials are drafting rules for the auction.

    So, google is proposing that the winner of the spectrum should open up his network.

    What do you mean by “opening up the network ” ?

    Consumer who is going to buy the service from the operator, should be able to
    - Pick up any handset he wants (iPhone is available only with AT&T)
    - Download ringtones, games and any other software including skype,etc from any vendor

    Sounds a modest request ?
    Not so, for the incumbent operators.
    Things are tight locked at the moment.
    Consumer can’t make a free choice of the handset and services from different operators.

    Why should it be so ?

    When you buy a new laptop, the seller of the laptop does not obligates me to install WinXp or RedHat,
    He does not tell me whether I should use google talk or Y! messenger.

    This is what google is asking.

    What will google gain out of this ?

    Opening up of a network allows new entrants for the auction.
    You will have more operators to choose from.
    Accessing wireless internet will get cheaper
    You will use Google services!

    Do you see something more ?

    Why am I no-believer ? 

    My first video post on this blog. I wouldnt have found a better one to post.
    Atheist : youtube video

    This is what I mostly read as I grew up. Darwin, Freud, Marconi, Hertz, Feynman. They were a more believable stories than the marvels of Lord Krishna,Shiva, Shirdi Sai baba etc

    A well presented reasoning always won over an abstract, vague and disillusioned concept of God.Luck, randomness or destiny may not still be explained or captured in any laws of physics, but it no way it makes me a fan of God.

    “It is far better to grasp the universe as it really is than to persist in delusion, however satisfying and reassuring”

    - Carl Sagan

    Along the same lines, check this one out. This is not to offend your religious sentiments. One for a good laugh.

    Pirates of Silicon Valley 

    I was watching this movie Pirates of Silicon Valley, last weekend. Hugely entertaining and informative at the same time. Purely made for geeks. Sorta spoof but not far from the real story.
    All about the historical battle between Microsoft and Apple over the War of PCs and OS.
    You get to watch younger nerdy Bill Gates, Design God Steve and wizard Woz.

    You will know why Steve Jobs hates Bill Gates, what made Woz quit Apple, Who is ‘Lisa’ and other interesting incidents in their life. Once you finish watching read this page.

    In the same breath, check this out. There is more to Apple than just iMac,iPod and iPhone.


    My friend Niranjan, pointed this interesting video of Steve and Bill, going down the memory lane.

    Grandpa’s will and IP subnetting 

    IP addressing and subnetting. Any number of times you read and try to apply, the basics evaporate in no time. Subnetting is little tricky and hence needs working through it to stick in the head. Let me make an attempt to give you some help in grasping the concept.

    Get this one right. Subnetting is all about dividing a large network to a fairly manageable smaller groups or sub networks. Even before we go and divide the networks into smaller groups, it is divided already into class A,B and C networks. Let’s understand this division first.

    Imagine this. Grandpa in his last days left a will to three of his sons Ason, Bson and Cson. Ason is eldest and Cson, the youngest.

    To keep everyone happy and avoid any possible conflict Grandpa has done some homework and marked all the land he has to pass on. This is a clever division keeping in mind that eldest should get the lion share but again younger ones should not be disappointed. Hence the shape of the property.

    Ason gets the taller box. It can accommodate only few but very very lengthy streets. So he can build many number of houses in a row. Bson’s box is little regular shaped. It can accomodate average number of streets and average number of houses per street. Cson has got a narrow wider strip of land, so he can have very few number of houses but large number of streets.

    Class A network can have – 128 networks [streets] and 16 lakh machines [houses] per street. Class B can have – 16000 networks [streets] and 1/2 lakh machines [houses] per network. Class C can have – 2 lakh streets and just 250 machines [houses] per network.

    Once this land is handed over to these three sons, they can rework within the allotted area . It’s upto the individual to come up with the desired number of streets and so many houses per street. So this is where subnetting will begin.

    If Cson decides to increase the number of streets he might end up with an absurd situation like having one house per street. Similarly, if Ason decides to keep very few number of streets, he might have to line up the houses for miles together in a row that it may not be called a street.

    So, a balance needs to be found in keeping the street length reasonably lengthy and with good number of houses. This is what subnetting is all about.

    PS: Well, it took me nearly 6-8 hours of constant thinking to pick the topic, state the problem, referring the text, spin a story and illustrating with the free hand cartoon. Believe me, it’s not as easy it looks here.
