Creating a RFC822 compliant date in php is a snap...

$rssDate = date("r");

in asp.net this is a bit more tricky. microsoft doesn't have a native RFC822 date format, so we are going to have to convert our dateTime.now() into that format...

I just got home from the tattoo shop and its 4:15am!!!!! these kids who think they are baller's came in at closing time (that’s 9:30pm btw) and all 3 wanted to get a piece done tonight. don’t get me wrong, i seriously don’t mind staying late at the shop, but 3 pieces! and of course, they were all large pieces. tony had to have make at least a G tonight, and i got a $50. how generous, after i looked up all these classic pieces of artwork, showed them to the guys, helped them decide which one to get and where (cuz they had no idea what they wanted) then scanned in all the images, cropped them, sized them, adjusted the contrast, and printed them. then had to wait around while tony tattooed them all night long. whatever. all i’m saying is 13 hours is a long time to hang out at a tattoo shop.

so i guess that quasi-apprenticeship at hot-rods paid off. i was recently approached for a job by a friend of mine named tony varlas at egobrain tattoo. as a graphic designer, webdesiner, computer technician, photographer, and piercer. the shop is located in downtown steubinville, so the work is mostly walk-ins. business has been slow so far, the shop is brand new, so i got paid yesterday in free work. a note about my new tattoo. the * in computer is called the wildcard. it is anything and everything with in a set range. it is used in random number generation and search algorithms. so yeah, i got an asterisk tattoo in my mouth.

i'll be working both the oakland and south side shop. im excited and scared at the same time. i wouldn't even pick up a needle for like 3 months though, which i think is a good thing. i'm going to work a lot with chris, which will be very cool. chris has been doing his thing for 9 years now and i trust he knows what he's talking about. This also means nina and I will be getting the hookup on all kinds of awesome jewelry.
