What Was The Last Thing That You Bought?

i hope her results are negative

which would be positive


depending how you look at it

 

My Mom was a breast cancer survivor. My aunt died of breast cancer so that places me at higher risk. I have had one annually for the last 30 years. So far no bad results.

Thanks for the good thoughts.

 

I couldn't resist.
I have a problem.

 

Well, I won't mention it by name, but it will lead to me running this old very poorly written program I wrote that does a rather nice job of hacking my brain. Maybe you can guess what it might be?

I don't get the code at all, but the blurb at the beginning makes me think I know what you got you are reminding me of a friend right now a lot. He's also a coder and he and an engineer buddy of ours hooked up this light machine that you stick your head in to get the same effects as your program. Have fun!

 

hehe ... you're on the right track. the code is bad, but it does the trick ...

The next thing i'm looking into is some LCD glasses/goggles, where I can send different signals to each "eye" .... and strobe between them in alternating fashion in order to see "impossible colors". My program actually already shows you a whole lot of stuff that isn't in the actual signal when you're tripping ... The LCD glasses are a bit expensive though.

see this wikipedia page for more info on what i'm actually talking about building (and nobody better steal my ideas and make money off of it, i do it for the lulz and lulz only ... if you build it and become a millionaire ... you better buy me a case of beer, or a few bottle of fine scotch ... or some LSD )

This track! I couldn't find it on my usual go to website for purchasing music, so I messaged the DJ on FB to ask him where I could buy an MP3 of this track, and he actually got back to me.

I paid 1.49 for it, but who cares. I am obsessed with this track right now.

 

New screen for the patio door and spline and the roller to put it in the groove.

 

strawberries that are going down the hatch as i type

 

Was getting myself a treat of dark lindt chocolates. They were supposed to be half price but the discount didn't scan up at the register so as per the supermarkets scanning policy, I got them for free.

 

That dj was probably really happy to find someone who actually wanted to pay for their work instead of downloading illegally.

 

Two loaves of bread - I only purchase Whole Grain Bread







Hotwater

 

Router table/shaper.... with router attached. 5 bucks at Goodwill.

 

i bought a container of macaroons


but by the time i got home it was a container of macaroon

 

3x pairs of sheepskin boots for only €4 euro! I got my partner 3x pairs too. Should keep us happy for half a decade. Then I got a cardigan to make up for free shipping.

Then on eBay I bought a bottle of Aramith billiard cleaning/polishing spray.

And the 1995 Jeff Gordon 1:24 Darlington race win diecast.

Can of monster absolute zero energy.

 

I put $10.43 on my Starbucks giftcard.

 

bought some strawberries today 50% off ....

dont know why they were reduced they look and taste just fine....$1.23 is a great price for such a tasty pile of things

 

Yeah, he said he was really impressed, actually. He even hinted that I download it illegally, but I told him I do not steal my music and would prefer to purchase the track.

 

I ordered pizza.

I also had excellent luck at a little gem of a thrift store I went to on the North Shore yesterday. I bought three pairs of Lulu Lemon pants, two Lulu Lemon sports bras, and an authentic Juicy Couture Purse for $70.00. One pair of Lulu Lemon pants is $100.00 new.

 

Forked Out $ 6000-00 Towards An Eye Operation At The End Of This Week.........Iv'e Been Legally Blind In My Right
