random: swiss army laptop backpacks

i have been recently amazed by the sudden apperance of swiss army laptop backpacks (well there is the possibility of a confirmation bias here .. but lets set that aside for now). too many people seem to have the same brand of backpack.

i figured there must have been some kind of promotion or sale forcing such a monoculture but couldnt find anything of note. a little bit of inquiry revealed that the bags were on sale at sams club (www.samsclub.com/shopping/navigate. do?dest=5&item=361436&pCatg=5791 ) and were a good deal.

for the record, i think the backpack looks good.

google checkout - bug?

google checkout consistently gives out 10$ off for anyone signing up for a new google checkout account -- the cost of creating a new account is trivial. and as far as i can see there is no conscious effort to correlate credit card numbers or address information to prevent the obvious cheat of creating bogus identities to get 10$ off each time?

as i watched water boil (no it doesnt affect it :-) ), i noticed that the steam/vapor induced a shadow on the wall but i couldnt actually see the vapors.
a. are there other such examples where things can be seen in shadows but through eyes?
b. is this because the human eye doesnt have sufficient resolution -- e.g. would a hi-fi camera pick it up?

karma, reincarnation, and conservation

suppose you believed in reincarnation -- in that case, is there some sort of a law of conservation of "souls"?
that is, the total number of "souls"that exists is a constant, its just that the manifestations are different.

couple of thoughts:
1. the definition of what has a soul is fuzzy -- does a single-celled amoeba have a soul?
2. it seems that the total number of life-forms is in fact increasing over time (even not counting bacteria, amoeba etc). this seems to contradict what little i understand of karma etc, the number of souls is strictly decreasing over time (some attain moksha).

public libraries and piracy

the music/movie companies seem hell-bent on going after p2p apps. i wonder how much market share they lose because of public libraries -- i would imagine that many decent public libraries have a good music/movie collection and that members can easily rip/copy the songs/movies when they check them out.

wonder if these folks have looked at how much revenue they lose because of public libraries.

i guess the riaa/mpaa could
a. go after public libraries to shut them down or stop supplying them with audio/video content
b. introduce specialized drm-ed versions for public libraries/lending services

in hindsight
a. this also applies to dvd/cd sharing services that are physical p2p apps
b. book publishers as well -- why wouldnt they want all readers to purchase rather than use libraries .. and why dont they make nearly as much a fuss as the riaa/mpaa folks?

the answer seems to be that electronic media significantly reduce the overhead of sharing and amplify the potential revenue loss .. and so theres not much to be gained by going after the physical p2p/sharing models.

piecewise linear vs smooth interpolation

suppose you are given a bunch of points on a plane. is the natural thing to consider a smoothly interpolated curve passing through the points or do a piecewise-linear join of the points

(it seemed to me that when the points have an naturally appealing polygon shape, then the piecewise linear interpolation occurs, otherwise the tendency is to draw a smooth curve through the points)

evolution ..

in high school when we were taught things about evolution/natural selection -- i somehow got the impression that species were explicitly trying to adapt to their environment, i.e., each animal somehow consciously tries to grow a longer tail or sharper claws or change its color to survive better.

now that i understand it slightly better this mistaken notion has since been dispelled -- its not the case that each species/animals consciously try to adapt -- the truth couldnt be farther away from this. the truth is that random shit happens, and the random shit that turns out to be best adapted to the current environment has greater probability of survival and there is an observational bias -- we only see those species that have the beaks/claws/colors best suited to the environment (the rest have been exterminated!), giving us the impression of some conscious effort by species to adapt to their surroundings.

optimally sizing free samples

whats the tradeoff between how many/much of a free sample give away. presumably you want to give enough so that it is sufficient to get the user to form a habit of using the product and then have them hooked on (not addicted just mere habit forming). at the same time you dont want to give away too much since it obviously eats into a potential market and also incurs losses.

wonder if there are some studies on how long an activity should be sustained for it to become subconsciously ingrained as a habit?

woodpeckers and moral victories

this months natgeo is carrying a short blurb on how the research into woodpeckers headbanging is useful.

i feel like i can claim a moral victory.

credit cards and rental insurance

why do credit card companies cover some portion of the rental car insurance -- it seems like they shouldnt be in the business of doling out rental insurance.

probably, many of the claims that people made for having been wrongfully charged on the credit card had to do with rental car companies (who are known to be pretty strict about damages etc) which id imagine that customers would claim they were wrongfully charged by the rental company and the credit card folks figured it would be cheaper to offer the insurance rather than spend the money in fighting the claims over unfair transactions.

anyone have better ideas?

{again based on observations from minesweeper}

fan speed ordering

the fans ive observed in the US have the fan speeds ordering: (off, max, max-1, max-2,...)

--> this makes sense if there is a binary choice users want -- either you want the fan turned on at full-speed (e.g., in summer) or turned off. makes sense in that it minimizes the number of state changes between desired and undesired states.
but if for some reason, users wanted an intermediate speed, then it is suboptimal since it may require more state changes


the fans ive observed in India have the fan speeds ordering: (off, 1,2,..,max)
--> this makes sense if the user wanted to figure out what speed-level wants, and then wants the fan in that state for a long time. but i cant figure out why users in India would want this -- presumably they want a fan with just a binary choice (off or on-at-highestspeed) given that summers are more brutal in tropical climates.

mast kalandar!

aug 27, scene 1: random thought at work

was listening to some hindi song with the refrain "mast kalandar" .. got me thinking -- who/what is this kalandar thing? and more importantly why is it "mast"?

aug 27, scene2: reading an article about pakistan in national geographic sept 2007

"whirling dervishes glorify the shrine of lal shahbaz qalandar, a 13th century sufi saint who preached peace between muslims and hindus. a faith embraced by most pakistanis, barelvi islam combines sunni with shiite and sufi mystical traditions. believers flock by the millions to such zones of peace where the oppressed and the powerful worship side by side"

{dervish: a member of any of various muslim ascetic orders, as the sufis, some of which carry on ecstatic observances, such as energetic dancing and whirling or vociferous chanting or shouting.}

ok .. so the mast kalandar could actually be mast qalandar, and "mast" could be some reference to a state of spritiual enlightenment/fervour associated with the qalandar thingie.

aug 27, scene 3: wikipedia to tie the loose ends

http://en.wikipedia.org/wiki/Qalandar
http://en.wikipedia.org/wiki/Mast_Qalandar

postscript:
actually, i lied a bit. even though i presented the events happening in the order scene 1/2/3 .. reality is that physical access to wikipedia is nearer than to the latest issue of natgeo .. thus the real events went scene1/3/2 -- but the weird coincidence that i should think about qalandar in 1 and see it in part2 on the same day still holds!

the sequence of events presented above (1;2;3) make for more interesting reading than the sequence 1;3;2. ive taken some creative liberty in narrating the events in the order 1;2;3 as it does not take away the essence of the interesting coincidence.

lax policy enforcement

A. How to steal a book from a library:

If you happen to take a book that has not been officially checked out the library has some sort of detector that checks if the item has been demagnetized or not (something that happens only when you officially checks out). in case the item has not been demagnetized an alarm goes off and a security guard asks for your receipt .. theres apparently a non trivial false alarm rate which entails the manual check.

however, heres a simple trick: officially check out item A but steal items B,C.... when the alarm goes off show the receipt for item A and the guard will let you go.

easy fixes:
1. always check all belongings when alarm goes off (high cost for consumers and security guard)
2. keep item A aside and make you walk through the detector again (if it still rings do step 1)


B. How to get free soda at a fast food joint:
simple thing is to ask for a cup for water -- they obviously wont deny you a cup. then you can easily get anything you want from the soda vending machine.

fixes:
1. make all filling (soda/water) go through a salesperson (i have seen these in some places)
2. have special water glasses that will make a loud noise if you fill anything else and thus serve as an embarrassing deterrent.
3. make only bottled water available!

in B the cost of implement it seems that the cost of implementing the fix is greater than the perceived benefit, so it probably justifies why stores dont care about the occasional guy stealing soda, but it doesnt seem to be the case in A (since a book/dvd lost means denying access to a potentially large userbase and high overhead in replacement etc).

P.S: I havent really implemented these attacks in practice :-)

maya.

before heading off to sleep last night i thought i saw a cockroach-like insect in the apartment and also thought i had killed it with a rather heavy book.
in the morning when i woke up the insect wasnt to be found -- either it had miraculously recovered and escaped, or the whole thing was just a figment of my imagination .. now im not so sure if i really saw and killed the insect.

made me wonder we need some sort of logging mechanism for the brain would be useful .. it would help to distinguish physically recorded events and things that are just figments of imagination .. which leads to the question of whether it is really possible to distinguish between observations and what we think to be observations (my intuition is that the neurological patterns characterizing real events and imagined events would be quite similar, i.e. the same set of neurons fire both in the real and imagined worlds) ?

wonder if they do the same thing for women's wear or the more upscale denim varieties or if its only for the basic line?

blogs and web graphs

i wonder if the amazing rise in the number of blogs has significantly altered the structure of the web-graph. extrapolating from a limited perspective of the blogosphere there seem to be more small-cliques forming this way than in the "regular" (if ever there was such a thing) web structure. i imagine at the macroscopic level (degree distributions and powerlaws) it wouldnt have any serious impact because those are just simply how natural human pheomena seem to manifest themselves .. but at some finer granularity are there a lot more (semi-)partitioned small communities in the graph now ?

one thing is certain .. im sure some data mining grad students out there are churning out papers on this

buses, thrills, and happiness

is there more reason to be happy if something happens by accident as opposed to be design .. theres some inherent thrill/greater sense of happiness in catching a bus just in time and sprinting for it rather than looking up schedules and landing up at the bus stop at the prescribed time.

somehow goes back to my earlier thoughts on happiness/RG -- there are few absolutes, most are only relative measures. happiness essentially translates into a effort vs. reward tradeoff or expectation vs. realization tradeoff.

"jesus is alive"

so am i .. whats the bloody point

{response to a sign seen on the highway}

first names

ive recently come to realize that its very rarely that i use the first name when referring to people. im more comfortable using pronouns or whenever possible completely avoid nouns. when i email/chat its usually "hey, hi" not "hey joe or hi joe". somehow subconsciously the use of the first name seems to imply some degree of familiarity with the persons and that the familiarity falls into some well-defined role. incidentally, the use of terms of like "dude, man, da" are amazingly useful substitutes for a name when talking to a guy.

what is additionally enlightening in this context is the fact that my nephew consciously avoids using my name when referring to me in a conversation, not only in a one-on-one conversation but even when trying to use a name whie talking about me to someone else. In this case I think the kid is confused on the actual role and the nature of the interaction between us -- Im supposed to be the "older uncle" but I also happen to play (reasonably competitively i may add :-) ) at his level so he probably also views me as a play buddy. Im assuming that there is a fairly decent level of familiarity so the only confusion arises because of the fuzziness in the definition of the roles.

In my case, the reluctance to use the first name has little to do with the definition of the interaction (i think this is a reasonable assumption to make). It just seems to me that using the first name is a big leap for me in terms of familiarity/conversational commitment so its a safer bet to avoid it. The other serious difference is that I have no problem using the name in a conversation with a third-party (as opposed to my nephew who doesnt .. whether hes making a conscious attempt to be funny or whether hes actually confused on how to refer to me i dont know for sure)

"Whats in a name" you might argue: I agree there is nothing in the name per se, but the process of using the name seems to be associated at some lower level with other things. If all of us had number tags (for those close to networking research you might think of "semantic free referencing" :-) ) , would I be comfortable referring to you using your number? I dont really know ..

So
1. if we are on talking terms, and
2. youve never seen me referring to you with your first name, and
3. have actually noticed it, and you have a problem with it
please let me know :-) and i shall re-evaluate the situation and/or consciously try and use your name more often.

geek selling power

how would you like a large population of people who are willing to canvass and sell your product for little or no fee. even better if the opinions of these people are respected by others. pretty sure this is precisely the freebie ploy used by companies in colleges. im guessing that people would trust young/geeky folks on matters of technical advice and if these people are observed to be obviously flaunting some particular product (e.g. google t-shirts) then they are likely to trust the product even though the advertising media (the bearer of the freebie) is oblivious to the marketing ploy

ceo salaries and academic tenure

read an interesting argument in the armchair economist which tries to explain why the top ceos (even those in arguably failing companies) take home very high salaries and even if they are sacked are given very attractive severance packages. the argument is that most shareholders (at least the bigger players) have diversified stock holdings and the failure of one company doesn't affect them seriously. however they stand to benefit significantly if a particular risky investment pays off with huge returns. thus they have very strong incentives to encourage ceos to take on high-risk high-reward projects and the high salaries are essentially a buffer mechanism to assuage any fears the ceos may have of massive financial distress in the event of the project failing to yield the expected return.
couldn't help but imagine the parallels with the academic tenure system. faculty are evaluated after the tenure period and given academic tenure, essentially giving the guarantee the position for the entire lifetime even if they are absolutely unproductive. on one hand the system seems flawed, there is no real penalty for senior professors to become very unproductive. on the other hand the above economic argument would suggest that universities (the investors or shareholders) have massively diversified assets -- the non productivity of one faculty member does not devalue the universities reputation. but if a high risk high reward project succeeds bringing in huge visibility (and of course funding) the university stands to gain a lot -- tenure is essentially the buffer (similar to the high salary) to encourage senior professors to take on riskier projects (of course no one cares about graduate students, they are a low investment and low return of investment since they will graduate and go elsewhere!)

kids as multiplicative adversaries

some consolation

should you be pleased if you lost to the two best teams on display that went on to contest the championship?

discomforting comforters

its disconcerting to note that you went to sleep without having your comforter over you and without a conscious model of where it is on the bed, but you wake up finding yourself within the comforter and with no knowledge of how it got there. disconcerting because it is possible that you have no control over your actions while sleeping

gait

was amazed that it is possible to identify an acquaintance (not someone that i meet very often) from a reasonable distance just from the gait!

introductions

why bother introducing yourself, when the probability of a repeated rendezvous is negligible?

early vs delayed decision making

do we want to get answers early and know that we have failed earlier .. or do we want to delay decision making until either the situation changes so much that the original decision-question disappeared or the decision made itself thanks to the actions of external forces? i guess a related question is how much control do you want or how much do you trust randomness in the environment? i appear to have argued in the past that delayed decision making is good ( here )

p.s: someone actually had a thesis on a strategy called "win or lose fast" for playing AI games and managed to get an honorable mention for it

unpardonable

just because your login-name is surprisingly close to ur real name doesnt give one the right the arbitrarily chose to assume that the login name is the real name :-(

phonetic biases across language families

would have imagined that the frequency of distribution of phonemes/sounds across languages should be relatively identical. the reason being that i would imagine that there is little genetic variation in the structural makeup of vocal chords and other sound producing entities, which would imply that the sounds which are easiest to produce would find their way into a significant portion of the vocabulary to minimize the difficulty of communication. strangely i observe that different language families have very different probability distributions ( far-east have a lot of "n", middle-east have a lot of "h" etc) .. wonder if there is any linguistic/genetic basis for these or am i just imagining things? strongly suspect the latter (finding observations to fit hypothesis to justify the hypothesis :-) )

effects of globalization ..

i find it odd that the last three pieces of clothing ive bought in the us have all been manufactured in the middle east (jordan, uae, oman) .. surprising because i didnt particularly expect the middle east to have a manufacturing sector that would be profitable, least of all for garments!

music industry, persistence, and self-fulfilling prophecies

continuing in similar vein to the earlier post on music vs books vs movies -- it appears that the appreciation or acceptance of a piece of music often has to do with repeated listening. the more often you listen to something, you invariably end up subconsciously starting to hear it in your head, humming it, "liking" it etc. this has pretty positive implications for big-label music records and popular musicians -- by definition they have more resources at their disposal to ensure that they are very visible (or should i say audible) on radio shows, music channels etc, and thus perpetuating the popularity further .. how do the smaller bands ever manage to break up the monopoly?

deadlines..

geomblog had this interesting post about why deadlines make sense ..
http://geomblog.blogspot.com/2006/10/deadlines-manic-behaviour-and.html

one obvious reason why deadlines make sense is the 80-20 (or is it 90-10) rule .. more than 80% of the work gets done in less than 20% of the time before the deadline

again a lesson from minesweeper .. performance seems to at its best when you are completely unaware of either your current performance and the objective in mind .. if you know you are close to the target you may tend to speed up (this is common ive noticed this even in school days the temptation to cycle faster once you get near home is very high!) thereby increasing the risk of not reaching the objective.

"like"-minded

why do we like something we read/hear .. more often than not it is because we hear/see what we want to see .. especially in the case of non-fiction books -- invariably i like something because subconsciously/intuitively i already believe what the author is telling me to be true and the discussion serves as a coherent, well-elucidated confirmation of this intution .. i guess when people say like-minded they are implicitly conveying this?

the edge of losing sanity ..

when you dream about muthiah muralitharan scoring a odi century! (and thats the first dream you have remembered in a looong time..)

on avoiding temporal biases in ranking systems

looking at the imdb top250 list .. it is remarkable to see the bias towards recent releases .. for e.g the departed has already made it to the top 200 .. somehow the mechanism doesnt seem to be very robust since there is an inherently positive bias towards recent happenings .. wonder if there are standard statistical techniques to avoid such biases -- but again a classic counter-example is the shawshank redemption which was a huge failure but is still very high on the list due to subsequent dvd successes.

on sustainable eccentricity

how does one decide if a certain form of eccentricity is sustainable or not ..
there are obviously socio-economic factors that arise .. but it does some inherently dependent on the "i dont care/shamelessness" coefficient of an individiual to be non-conformist --> the "i dont care" value is what the eccentric person presumes to be the natural inclination to non-conformism, the "shamelessness" index would be a metric defined by the larger society for the same phenomenon but given a different name for obvious reasons.

aside: scientifically asymmetry seems to be associated with eccentricity .. why else would there be something called the eccentricity of an ellipse .. it appears to arise from a comparison with circles.

exploration styles

top-down vs bottom-up
breadth-first vs depth-first

many questions ..
which is the right approach if you are emabarking on writing a book/thesis?
which tends to happen more in practice?
which is more intuitively obvious?

timescales of religious upheaval

it seems that its been a long time since a major religion took root in the world ..
the time for the new messiah to arrive is quite ripe (at least on statistical evidence), especially since most people are arguably not happy with the state of affairs (both of their own and the world in general) so starting a new religion always makes a lot of economic sense since the incentive to switch is always higher for the consumer than sticking to the current product available.

ignobel?

who decides whether a piece of research qualifies as being ignobel or not ..

makes you ponder --> most research is never seen by the world do all those nameless works of research count as better research than the ignobel research?

also it appears that the committee for deciding ignobel awards tries to trivialize the nature of the research and makes it sound more funny than it actually may be ..

almost always the nature of ignobel research is decided based on the question that the research seeks to answer, under the presumption of course that the question is so esoteric to have no real impact .. this raises two questions
1. what about research that is ignobel because it suffers from methodological pathologies ..
2. a lot of pure-science/pure-math can arguably be quite easily categorized into the class of ideas that can have no tangible impact -- would these guys venture to classify that research as being ignobel?

as a last note .. the ignobel awards have a strong bias towards experimental/measurement studies -- dont see why this should be so!

p.s. the woodpecker research in this years ignobel sounds very legit to me .. this post sponsored (mentally not financially!) in part by that

nails and evolution

wondering why biting fingernails is a common means of expressing stress/tension in humans -- and this phenomenon doesnt seem to be have a cultural bias .. there must be some genetic/biological connection .. coz otherwise i would imagine there would be a wide diversity in the spectrum of symptoms that can be used to express stress.

lost ..

two consecutive days .. been losing stuff in a classroom .. remembering it 5 minutes after the class is over .. quite amazingly recovering the objects without any visible loss!
as a consequence started imagining that i had lost my laptop dongle while in fact i had not ..
senile dementia setting in .. running out of time :-(

did learn a lesson in this madness though --> doesnt matter if you do something wrong as long as you realize youve made a mistake quick enough to recover!

is research the art of ..

finding correlations where none exist

retro-fitting hypothesis to observations

extrapolating to large sample sizes from small subsets of data points

manipulating visual evidence to suit hypotheses

changing definitions to suit what you can prove

changing metrics to suit what you can show

lulling oneself into a false sense of intelligence

balancing on the shoulder of "giants" while being careful not to tread on their toes
