    Hardware Hacking Projects for Geeks and First Transistor 



    I picked up this book from British Library. But read in parts, sparingly.
    This is what we missed out in college days…hacking around with hardware using our electronics-engineering skills. I still fear laying hands on electrical equipments.
    Can somebody teach me…handling basic electrical appliances, measuring voltages and current, how large is 1 Ampere and some electrical wiring, fixing,soldering etc.

    Physics in 20th century, the book I picked up from Book exhibition has this picture of the first transistor and there’s a description of “Controlling Resistance”.
    What caught my attention when I browsed the book, was this.
    It reads something like this:

    Researchers knew, that it should be possible without any mechanical devices, by exploiting the properties of doped semiconductors, that a weak current could be used to vary the resistance of the middle semiconductor, just like a small amount of energy can raise and lower the canal-lock gate.
    They tried various combinations and finally figured out that two n-type devices separated by a layer of p type semiconductor (like a gate) could do the magic.

    I don’t think I still have understood it quite well enough…but that aha moment is not very far.

    SrihariKota Flashback 


    We went to SriHariKota, around 2 years back from Birla Institute of Fundamental research,as part of sight seeing.
    Life at SriHariKota is quite different from living in any other town of India. It’s a self contained town and houses only the big brainy staff members.
    I still remember the person who showed us the master control facility with outshirt and Hawai chappal, only later to realise that he is a senior scientist.

    It’s still fresh.
    Touching the inner surface of the rocket fuel containers.
    Stress Test site, where they put the rocket in horizontal position.
    Library and excellent staying facility.
    Early morning walk around the place.

    SriHariKota is very special and strategic for Indian space advancement.

    When we went there we’re just 30 days away from the launch of edusat satelite launch. I felt very proud for having got the opportunity to visit this unique town…which otherwise requires special permission because of security reasons.

    My old friend from RC school in Shimoga, called me up this morning for his marriage invitation. Very glad to know that he works at Kalpakkam.
    Wish I visit this site as well someday.

    Bangalore Tiger 


    I was at Forum’s Landmark. Launch of Bangalore Tiger by Steve Hamm.
    Uh. Not an impressive one.
    Book is about wipro and blah blah blah.

    I never thought Wipro’s story is interesting enough to be read.

    There was a question from the audience.
    How do you compare your book with “World is flat”

    He said
    “World is flat awakened everyone about the rise of asia.
    Bangalore Tiger is going to tell you what happened after the awakening”

    In one of my prevvious post I was wondering about the worth of
    IT industry on the globe.

    I heard it today. It’s 600$bn!
    Wipro, infosys and TCS put together make some 5$bn !

    Safari Books Online 

    Big savings on my pocket. Now am a subscriber of safari online.
    Online versions of o’reilly books.
    I bought 500 Rs worth of O’reilly books only last week.
    Could have saved on them.
    O’reilly books, known for theiry geeky and hacky nature, their online version, is such a great help. So, google will step aside for a while for my tech-needs.

    One Phone. Many identifiers. 

    We have to remember only one number.

    But the network elements…are very very very busy.

    TCP IP illustrated Vol 3 

    If there’s only one road and there’s only right turn,
    does it make a difference by putting up a signboard, “Right Turn”

    That’s the case with TCP/IP.

    It’s not a clever protocol or something very special about it.
    This is the way any sensible would have implemented.

    So, debate of whether it’s a superior protocl or an inferior protocol should not exist.

    I read few pages of TCP/IP illustrated Vol 3 at Bangalore book festival.
    That was the revealation.

    Bangalore book festival – Nov 11 2006 


    Blogging from Bangalore Book Festival.
    But it’s little disappointing not to find wi-fi not working here today.Had tucked in a laptop, after I read about this in news paper y’day.

    Been third timer I guess here.
    There has been a sea change in the way I pick the stall and the book.
    When I was here for the first time, it was an overwhelming experience. Loads Loads of book greeted me and I could not see any pattern emerging.
    Today after years of experience behind me, of browsing the shelves, it takes just few seconds to ‘judge a book by it’s cover’

    What titles I was interested in this time ?
    Visual History of the world
    Books on wireless and networking in general.

    I have picked up two books so far after two hours of scanning.
    CDMA2000 systems
    - I had another book of vijay. k garg.
    Content,look and feel of this book also is similar. But it’s always interesting to know how the same topic is dealt by others.

    Basic electronics by schultz.
    -Striking a balance between the Theory with practical example and still covering problems which might appear in ’semester exams’.It’s always difficult to achieve all the three in one book.
    That’s what I always expect in a tech book.

    I read few pages of TCP/IP illustrated in the store itself.
    Was kind of a revealation. More about this in a separate post.

    why do we need logging ? 


    I was to tell them the importance of logging in softwares.
    Especially in a call processing software.
    Can there be a better imagination than this ?
