h4x :: console modification for better sound recording

nintendo gameboy prosound mod

today’s mod is for the original nintendo gameboy. if you want to get serious about chip tunes, whether your using lsdj or nanoloop, the sound quality of your instrument is a priority. the stock nintendo gameboy is equipped with a single headphone jack. and if you have ever tried recording anything from that, it sounds pretty bad. thus the prosound modification was invented to add a line out jack to the gameboy.

inline SQL statements

sql :: nested queries in MSSQL

the world of database programming can be a dark and treacherous journey. when you first set out, your quest seems manageable. but as time progresses your start to realize you need more queries, more tables, etc, etc, to achieve your goal. well today i’m going teach you a little trick that might help you need one less stored procedure then you thought...

sometimes it’s true, you actually do need two queries to get the job done. but other times you can circumvent this by using something like a "join" or "inner join" query to merge two tables together and pull your results from both.

but the optimizer in you says that still isn’t enough...

PQ torus knot

demos :: papervision3D math art

papervision3D PQ torus knot

here we go again, another papervision3D demo featuring math permeated lines. this time im working with a classic piece of code known as the PQ torus. the vague idea is that you have 2 numbers (P + Q) that are used in the algorithm to define the knot. in general, given P + Q mutually prime, the line wraps meridionally around the torus P times and wraps the longitudinally around it Q times. i was having some trouble grasping exactly how this was going to be achieved, until i read this article on blackpawn’s website. he really breaks down the algo to a very simplistic level...

h4x :: DIY portable RF jammer

NYC cityscape

i just got clued in on a new project from one of the members of the cDc (cult of the dead cow), a notorious hacker group from way back in the l0pht days. the wave bubble is a self-tuning, wide-bandwidth portable RF jammer. an internal lithium-ion battery provides up to 2 hours of jamming (two bands, such as cell) or 4 hours (single band, such as cordless phone, GPS, WiFi, bluetooth, etc). the battery is rechargeable via a mini-USB connector or 4mm DC jack (a common size). alternately, 3 AAA batteries may also be used. self-tuning is provided via dual PLL, therefore, no spectrum analyzer is necessary to build this jammer and a single wave bubble can jam many different frequency bands...

life :: photos from our trip

NYC cityscape

i was just on vacation in NYC. the crew was myself, nina, and our friend nik. nina wanted to check out fordum university, and visit our friend john who lives in yonkers. not to mention that she had never been to the big apple before. we spent four days in the city, spending 75% of our time in museums, 15% in restaurants, and the remaining 10% walking/riding public transport. but when the sun went down we had a shofar. john (aka jaze juce) is a native new yorker, who nina met at school. jaze is a rapper, a life guard, and all around man about town. we saw a lot of the city from in the car at night, which was awesome.
