Joining a challenging new-born internet start-up… called Delver

August 30th, 2007 by Moti Karmona | מוטי קרמונה · No Comments

GOOD LUCK (FU) Chinese CalligraphyAs I posted when I just started this blog – Almost 2 month ago I have decided to leave a promising (& cozy) career @ Mercury to join a challenging new-born start-up… called Delver.

This was an offer I couldn’t refused…

Delver is a venture-backed internet startup developing cutting-edge web application in the domain of Internet Search and Meta Social Networks.

It is more challenging, inspiring, interesting and exciting than I expected, imagined or I can put into words so you will have to join to understand… We are looking for top-notch algorithm researchers, .Net coders, mySQL DBAs, “Hackers”, QA experts and out-of-the-box thinkers… to join our unique development team (e.g. Pitz, Boo and Gabel)

Stay tuned (…)

déjà posté

August 28th, 2007 by Moti Karmona | מוטי קרמונה · No Comments

déjà vuThe term “déjà vu” describes the experience of feeling that one has witnessed or experienced a new situation previously.

“We have all some experience of a feeling, that comes over us occasionally, of what we are saying and doing having been said and done before, in a remote time – of our having been surrounded, dim ages ago, by the same faces, objects, and circumstances – of our knowing perfectly what will be said next, as if we suddenly remember it!” – Charles Dickens

In recent years, déjà vu has been subjected to serious psychological and neurophysiological research. The most likely explanation of déjà vu is that it is not an act of “precognition” or “prophecy”, but rather an anomaly of memory; it is the impression that an experience is “being recalled” which may result from an overlap between the neurological systems responsible for short-term memory and those responsible for long-term memory.

In other words, “déjà vu” is yet another careless data inconsistency situation due to poor synchronization mechanism and hectic multithreaded race-condition incidents a.k.a. “Dark-Voodoo” bugs (e.g. “déjà vu” ;-)

There are many ways in which the deja experience may manifest: deja entendu – already heard; deja eprouve – already experienced; deja fait – already done; deja pense – already thought; deja raconte – already recounted; deja senti – already felt, smelt; deja su – already known (intellectually); deja trouve – already found (met); déjà vécu – already lived; deja voulu – already desired; deja arrive – already happened; deja connu – already known (personal knowing); deja dit – already said/spoken (content of speech); deja goute – already tasted; deja lu – already read; deja parle – already spoken (act of speech); deja pressenti – already sensed; deja rencontre – already met; deja reve – already dreamt; deja visite – already visited and my recent favorite invention: déjà posté – already posted

Sliding Milestones @ California, Death Valley

August 26th, 2007 by Moti Karmona | מוטי קרמונה · 3 Comments

Sailing Stones = WaterFall MilestonesThe sailing stones, also referred to as sliding rocks or moving rocks, are a geological puzzling phenomenon found in California, Death Valley. These rocks, some as heavy as 300 Kilograms, are mysteriously transported across a virtually flat desert plain without human or animal intervention, leaving erratic trails in the hard mud behind them, some hundreds of yards long. They move by some mysterious force, and in the nine decades since we have known about them, no-one has ever seen them in motion.

When I first read about it, I thought it is very much like the notorious (software-management-)waterfall milestones – no one really see them sliding until it was too late and then everybody could stare @ the erratic trails in the mud behind them, some hundreds of yards long…

The Alexa Hoax

August 20th, 2007 by Moti Karmona | מוטי קרמונה · 2 Comments

Pac-Man ChartAlexa says YouTube Is now bigger than Google & that Orkut have reached 71% Brazilian users… (???)

I have merged the internet population data from the CIA FactBook (reliable source but not the most updated one) to a an (unofficial) Alexa toolbar users distribution and this is what I got:

CountryAlexa CIA Fact Book
China16.44%12%
United States14.28%20%
Brazil3.82%2.5%
Japan3.64%8.4%
United Kingdom3.11%3.6%

Alexa collects data with its toolbar – Did you install it? (I didn’t…) which mainly have implication in regional bias as the distribution of Alexa toolbars is not proportional to the number of users in different countries and as it seems Alexa doesn’t do any “normalization” of the data to fix this bias and doesn’t have any official report on their toolbar distribution – Alexa on Alexa is unavailable (???)

“Alexa Reach” is relative – the percentage of all Internet users who visit a given site rather than absolute number of users which is causing unexplained changes since the “total- distribution-pie” is changing all the time…

Alexa tracks “daily unique visitors” (a.k.a. “Alexa Reach”) and “daily page views” which isn’t like tracking unique (session-based) visits and I think that how many times did you refresh your facebook home page today (could range from 0 to 500 a day ;-) isn’t as interesting as the fact you did visit it today.So…

I don’t have a better alternative to measure other-people-sites-traffic yet (…) but I think Alexa can have much more interesting data by simply moving to more interesting counters (e.g. unique visitor), publish their toolbar distribution (a.k.a. Alexa on Alexa) and start doing some “normalization” with internet population data.
