Programing Thingamajig

Ishan, Abhay, Mukul, and I are planning on holding some sort of an algorithmic programing workshop day-after-tomorrow, that is on the 27th from 1:30 – 3:30 PM, somewhere inside of school (one would hope), and hopefully if you come around to the eGurucool lab on that day someone would tell you where to find us.

We plan on covering basic recursion, some amount of dynamic programing, and introductory graph theory, or some subset of those topics, depending on how much time we have on our hands, and as far as I know we would probably not be doing anything which would require you to prefer one particular language over another, however a basic understanding of itteration (that’s basically a suave way of saying that you should know about loops, though I use that as an example, know some amount of programing, you should have gone beyond hello world programs in at least one language), and such things would be helpful.

I know this is really short notice, and hence it would be really great if people spread the word around, and while I know there are a billion reasons why people would want us to shift the date around, however due to prior commitments it is unlikely that all of us would be able to make it to school on any other day, so we would really like to do this on Wednsday.

I hope to see some of you around on Wednesday, and I would really appreciate it if people spread the word around.

Holographic Versatile Disc


Holographic Versatile Disc (HVD) is an advanced optical disc technology still in the research stage which would greatly increase storage over Blu-ray and HD-DVD optical disc systems.
It employs a technique know as collinear holography, whereby two lasers, one red and one blue-green, are collimated in a single beam. The blue-green laser reads data encoded as laser interference fringes from a holographic layer near the top of the disc while the red laser is used to read servo information from a regular CD-style aluminium layer near the bottom. Servo information is used to monitor the position of the read head over the disc, similar to the head, track, and sector information on a conventional hard disk drive. On a CD or DVD this servo information is interspersed amongst the data. A dichroic mirror layer between the holographic data and the servo data reflects the blue-green laser while letting the red laser pass through. This prevents interference from refraction of the blue-green laser off the servo data pits and is an advance over past holographic storage media, which either experienced too much interference, or lacked the servo data entirely, making them incompatible with current CD and DVD drive technology. These disks have the capacity to hold up to 3.9 TB’s of information (whoa!) , which is approximately eighty times the capacity of Blu-ray Disc. The HVD also has a transfer rate of 1 Gbit/s.
