krishna2··on For Today’s Graduate, Just One Word: Statistics
Just like: Plastics

Of course, should add the obligatory remark: Lies, Damn Lies and Statistics.

krishna2··on Scoping out the Galileoscope: $15 telescope designed by professional astronomers
Just order a few more and then split the s&h withe friends/family. (which is what I did). Plus it is a great gift.
krishna2··on Microsoft-Yahoo Deal Struck, Will Be Announced Within Next 24 Hours
And it was Yahoo who served Microsoft's search results (via Inktomi). How about that for recursion ?
krishna2··on Microsoft-Yahoo Deal Struck, Will Be Announced Within Next 24 Hours
Long ago, it was Google who served Yahoo's search results.
krishna2··on Running 30" and 20" monitors side-by-side using a Macbook Pro
I see this for $69 in amazon.
krishna2··on Reddit: Hotel California of the Internet
Of course, I can also say that about a few other sites as well. ;)
krishna2··on Ask HN: your favorite obscure Firefox extensions?
LORI - Life Of Request Info

Awesome plugin for quick/constant perf measurement. It shows how long it took the browser to get the first byte, the total time for page rendering, the total size of page and the total number of requests. For example, for this page, the stats are :

0.160s 0.600s 26.14KB 5 req

krishna2··on Ask HN: Any Bay Area Hackers into running, cycling, triathlon, etc?
My advice is that you go to a professional bike store and get a decent bike.
krishna2··on Ask HN: Any Bay Area Hackers into running, cycling, triathlon, etc?
I just recently got into biking and am super excited about it that I wrote about it http://www.krishna2.com/blog/2009/05/eb2b-biking-from-east-b...
krishna2··on Blekko's ambient cluster health visualization
Well, you can read about that here : http://www.skrenta.com/2008/01/why_search.html and here : http://www.skrenta.com/2008/01/about_the_name_blekko.html
krishna2··on Ask HN: Carnegie Mellon or Stanford
Both are GREAT schools and consider yourself lucky to have a choice. I did my masters at CMU (and have lived in Pittsburgh for 4 years) but for the past 8+ years have been in the bay area.

The cost of living is very very cheap in Pitt, no doubt. Personally, I like having four different seasons - so weather was not a big deal for me. If you want consistent weather and clear blue skies, palo alto, it is. YMMV.

In CMU, you are very close to a whole lot of other big cities and universities - so travelling is lot easier.

So all that said, now to the important part: the important decision will be based on what your interests are. CMU is very strong in Robotics and Artificial Intelligence fields of study. Similarly, Stanford has its big specialties as well. So if you already know that you might major in Computer Science, try looking at the profiles and research interests of the computer science faculty at each school. Give yourself as much flexibility as possible here, because what you think/know now will be lot different in 2 years, 4 years and 6 years from now.

If you are entrepreneurial and you want to do a start up, then just close the circuit and take the shortest path - the bay area.

Or if you still want to do that, but take the road less taken, come here via CMU.

In anycase, read Robert Frost's "Road less travelled" poem. :)

Good luck.

krishna2··on Ask HN: Good coffee shop near CMU?
Kiva Han was our place to hack at. So much so we even named our then startup inkiva.com!!!
krishna2··on Why HN is slow lately
More people visiting a site does not make it bad..but more submissions and vote-ups could be the reason for the dilution. Just make that process as hard as possible. How hard can it be to make a user-unfriendly html-hiendish registration page, eh ? :)
krishna2··on My Web is Text Based
I completely agree and my visits to such sites have gone down as well. Other sites that I have stopped visiting less include sports.yahoo.com and movies.yahoo.com. And don't even get me started with tv.yahoo.com.
krishna2··on Google brought back oldest available index for their 10th birthday
Search for "SEO" brings up this : http://www.google.com/search2001/search?q=seo&hl=en&...

First hit : Welcome to the Sponsors for Educational Opportunity Web Site

They practically later defined that market.

krishna2··on Ask YC: Isn't the Chrome hype a little too much?
I was curious about the same thing and my keyword count script prints this :

chrome : 39 google : 37 startup : 12 web : 11 ask : 11 new : 11 yc : 8 browser : 8 code : 7 chromes : 7 javascript : 7 y : 5 windows : 5 best : 5 game : 5 chromium : 5 v8 : 5 link : 4 combinator : 4 talk : 4 write : 4 language : 4 hn : 4 python : 4 history : 4 technology : 4 programming : 4 twitter : 4 facebook : 4 live : 4 chrome? : 3 project : 3 erlang : 3 market : 3 whats : 3 source : 3 good : 3 friendfeed : 3 things : 3 adds : 3 company : 3 googles : 3 make : 3 job : 3 does : 3 engine : 3 inside : 3 application : 3 business : 3

krishna2··on How to leave a program running after you log out

krishna2··on 1/3 Rule
Essentially the middle-third (get back 1-to-2x the money back) and the bottom-third (lose money), hence canceling out each other [Assuming that the middle gives just 1x and the bottom loses 100%].

But the top third is expected to make 5-10x. So that gives .333 * 7, (assuming 7x), which is approximately 2.33 times the original money invested.

So every year if the investment is $100 and the eventual return on it is $233, that looks like an awesome deal. Why is everyone not doing it then ?? Whenever any scheme yields more than the long-term-market-average (approx 15%(?)), it is good to ask why and how it works, if it is indeed true. My guess is that there is way more risk involved and the one-third rule is an optimistic view as well as a very simplified theory.

So while it could hold good for a very good VC firm, it might not for every VC firm out there.

krishna2··on Ask YC: Startup atmosphere in Pittsburgh, PA?
Count me as another who considers Pittsburgh as home away from home. Would probably move back there for the right opportunity.
krishna2··on Ask YC: Where to start with creating a distributed crawler
+10 for Python +1 for Nutch +1 for Hadoop +1 for Amazon EC2

I think you have bundled two things (crawler and parser (or may be scraper)) into one term : crawler.

Beautiful soup is ok. Give html5lib a try (on google code) - but at some point you are going to have to hack the parser, but that depends on what kind of parsing you want to do.

krishna2··on "21", Movie about MIT Las Vegas Card Counters Opens Tomorrow
What Ed Thorpe did was just plain genius!!! And what 'rainman' (movie ref) did was beyond genius!

But IMO what these folks did was cheat. You can count cards as long as you do not use an external device to aid you in the counting. These folks collaborated with others to share each one's counts so as to take advantage of the system. Not that I am a big fan of the casino (or their making tons of money).

And after that they started a hedge fund and have been playing in the real big markets..ever since.

That (hedge funds) and all such things seem to be basically about one thing : Know of a statistical advantage that others don't know and then play mechanically with zero emotions as possible. Play for the long term, play for sensible gains/expectations and put risk-management above everything else.

[Edit] As I am thinking about this : Startups are probably a similar kind of game as well.

krishna2··on Ask YC: Dealing with post startup depression
Think about it this way : You got about 10-20% of the total and about (70-80% of the grunt) work done for your next startup. :)

You have your servers, source code repository, development environment, bug/feature tracking stuff and all that ready. Heck, you might even have got the logging in, authentication, monitoring and all that done as well.

I would go so far as to say : Everyone should do a dummy startup just to get all the above straightened out. :)

krishna2··on Ask YC: Any hackers who can provide advice on scaling (esp database)?
I am assuming you are using MySQL. If so, there is a very nice mysql performance blog. Definitely check that out. There is also a Mysql tuning book by mysql press itself and then there is Mysql High performance Oreilly book as well.

Plus, there are many simple rules to keep in mind as well. Use innodb when transaction (acid-properties) is important, but MyISAM when reads needs to be efficient. Normalize first and then denormalize (and duplicate data) later when you hit a wall. From the beginning, start with the assumption that there will be many databases and there will be many servers. There is also memcache which is just plain awesome.

Lastly, seriously think when and where you really need a db and where you can just use pickled-data/file-systems. [PG has said this many times as well].

Hope that helps.

krishna2··on How long did your U.S. green card take?
Oh..visit http://www.immigrationvoice.org/ - and post your exact scenario. Lots of helpful folks there. And if you search the archives, you might just find someone with your situation might've already asked the same questions.
krishna2··on How long did your U.S. green card take?
Actually, only the first time that you ever apply for a visa, you are fighting the quota. Then onwards, you are just reusing the same number - so no worries there. [this is good until the 6 years of eligibility of h1].

Secondly, if your application had been pending for more than year, then you can keep your h1 alive (even after 6 years), and use your pending-gc-application to get h1-renewals.

Lastly, if you get past the first two and a half stages of the greencard process and you get an EAD and you have worked 180+ days with your employer, then, as Southwest says, you are free to move about the country. :)

krishna2··on How long did your U.S. green card take?
They say the third time is a charm - and I am on my third application - pending for about 3 years. The previous two times (first in 2001, the company went bankrupt. The second time in about 2003, but I left the company after a couple of years).

Sometimes, it is just a matter of luck. There was one in 1998 (when suddenly everyone got "current" and could move on with life). Then, there was a period in 2000-to-mid-2001 when the whole process took less than a year (for even high-demand countries like Mexico, India and China). There was a recent event (in July/August of 2007) - but that was only a partially-lucky event since many bad things happened after that.

krishna2··on How long did your U.S. green card take?
The lottery is available to only certain countries' applicants. (Generally the countries which do not use the full quota due to lack of applicants).
krishna2··on Ask YC: A way to measure page render time?
I just noticed one thing. I added a comment directly. And was hoping that mine would probably go to the end of the list. But my response got inserted between posts by prakash and pg. Curious to see where this comment ends up.
