DB && Android

The last three days I've been doing nothing but studying for database and programming android, and I played a gig with my student orchestra.

Studying for database has been awesome. I've been studying small chunks of the course with a friend for like the last week. We feel really confident going into the final tomorrow.

A few days ago I started making a "Rock Paper Scissor" Android App. I can't believe I'm already finished. It's so awesome implementing the things I've been reading about: passing variables between activities with intents, calling the finish() lifecycle method so the app doesn't make a huge chain of activities, and the last part was dealing all with the animations between slides.

I really wanted there to be a little pause after the selection to build anticipation for the result. HCI eat your heart out  >.< It's been so much fun I cant wait to get it on the market and start working on the next.

Recovery Magic

After reading an article on data recovery, I downloaded some software to try it out for myself. Oh my gosh! I recovered a flash drive that I thought I had deleted everything from. I recovered files from three years ago!!! Pictures, files, documents everything was there. So amazing and so scary. Needless to say I'm now waiting on a 35-pass zero out on all of my flash drives.

Going Twice to Disk?

So in comp architecture today I learned that when using a data cache and a table look aside buffer to fetch instructions and data you could actually have to go to disk twice if you miss in the TBL and the cache. How crazy is that, like 100,000 cycles for one instruction... so much stalling.
