A beautiful image of tendrils of epoxy extruded by capillary action by evaporation of a solvent to hug a polystyrene ball. The color was added after the fact by an artist, giving the tendrils a caressing finger like quality. Science and beauty together.

Non locality in QM and Special Relativity, is it real?

A recent article at scientific american online, reviews the debate and latest research over the idea of non-locality as being a real quality of reality or simply an apparent one, as a consequence of the mathematical framework used to describe the quantum mechanical theory. It covers the various results revealed by people like Bell and Bohm, who provided elegant results that seemed to exclude locality from being a part of reality. Recent findings seem to coroborate those results and lend strenght to the idea that entangled particles are indeed connected in a "spooky" fashion that is independent of their physical distance. However, to me this idea is missing a big fact regarding the nature of reality. Namely, that our theoretical models of it, QM on the small scale and Special and General Relativity on the large scale are incomplete descriptions of the physical world. We still have not resolved the micro and macro worlds using a single theory that smoothly permutes between the…

web based malware vectors.

Yesterday I had a visit by a childhood friend, during the visit I wanted to give him an idea of why Flash based web chat services can be inefficient for large number of simultaneous users while chatting. Before I could get into my example, the Userplane chat room I entered sent the following message:


It says "Warning! Your PC is at risk of virus and malware attack. Your system requires immediate check! System security will perform a quick and free scan of your PC for viruses and malicious programs." followed by an ok button as shown. Well , my years using computers and warning people of the dangers of trojan horse like messages from web pages prompting users to run scans, quickly told me this was a false message provided by some script embedded into the Userplane room I was in, and triggered by my attempt to send a message into the room. This is really bad news for Userplane, as it means the public rooms on its service have been compromised by malicious code creators and is …

Delays

I was fast on my way to launching the site as I wanted by the end of the year, and then I ran into a bit of a bug that held my at bay for a week. It turned out to be a really foolish bug, one that I will not recount in this medium. Needless to say that the progress is back on track, I've got one more core implementation issue to finish and then the rest are javascript bug fixes and the launch is on the way....


stay tuned...
