Konami Code

Up, Up, Down, Down, Left, Right, Left, Right, B, A; when A, B are not available 1, 2 are used. Konami Code, to be entered before game demo begins during the title screen, enables the player to beat the game. First used in 1986 for players who found games too difficult to attain higher levels; these codes give a full set of powers usually attained over time.
Konami Code is the gamers' cheat sheet. Enjoy.

QR Codes

QR Codes were created in 1994 to track trucks during manufacting by Denso Wave; which is a subsidiary of Toyota. This pictoral two dimensional matrix barcode is comprised of binary alphanumeric Japanese symbols written in Chinese called Kanji; made up of multiple interwoven error correction blocks where data is placed from right to left in a zigzag pattern. Storage capacity is affected by high error correction. Four bit indicators are used to convey other information and to select the encoding mode. Japanese passports are encoded with a QR Code containing a 56 bit algorithm used for encoding visas.
Discussion D in 2011 was the last HICAP lesson on QR Codes. The author is revisiting this subject because QR is more popular than ever and showing up in magazine ads, on billboards, almost everywhere.
QR means quick response. The way to use these codes is to point your smart phone camera eye at the code to engage and the target url will automatically be uploaded to your device. Fun, right!

Zephyr whispers the Summer Solstice in at 1:04 am; this unique day in New York City is marked by 15 hours of daylight. In Anchorage, Alaska, 19 hours of daylight is experienced. On this day, the Harlem Internet Computer Access Program ends our HICAP 2012-2013 year. This year, we introduced, our Virtual Learning Lab; which translates and disseminates technical computer education facts.
The blog that you are currently visiting translates scientific data, provides technical pertinent information and highlights accomplishment.
Today's posting of Scientific Notation at the Virtual Leaning Lab will be the last lesson discussion for HICAPV until Fall 2013.
Enjoy Summer!
