RSA, Exponents, Mods, a Giant Firehose of 6.042

Well, Grace said that for her 6.042 Cryptography lecture, they spent one hour on Caesar Shift, and then crammed all of the other more complicated encryptions into the last 30 minutes of lecture. Well, that didn't really happen, since we had to review stuff (FlT, Euler's Totient Function, etc.), but it certainly felt that way today. After basically snoozing for much of Induction, Invariant, State Machines, and Modular Arithmetic lectures, this one definitely felt like a firehose of content in those last thirty minutes.

To be honest though, this firehose was quite refreshing for me. This lecture was basically what I imagined MIT to be like when I got here, scribbling down stuff, barely keeping up but it's not so ridiculously crazy that I don't know what's happening for the entire hour and a half. There's a sweet spot in how fast classes go, and I actually really like this one.

At some point today, I'll probably be in the study, working out some of the kinks in the Diffie-Hellman Key Exchange and the RSA Cryptosystem. Glad to see that a class that's been putting me to sleep before is getting interesting. Hopefully this keeps up :)

    Imagine not feeling sleepy in 26-100, sounds fun :))
    I hope more classes will hit the sweet spot as we get out of GIRs and early requirements; then we can finally TFP (truly find paradise)

Brain Dump

 Bruh... this has been an absolute hell of a week, so much that the last time I posted was four days ago... I'm going to pretend that I have troubles logging into my account to blog and not that I was too busy or was suffering from writer's block. And to be fair, this was the first thing that I saw when I logged into Blogger: That aside, I guess I'll just do a brain dump this time because I have nothing in particular that I have to write about. [A brain dump , according to Mr. Gartland (my APHuG teacher), is when a student doesn't know what to write about on an FRQ and just starts writing, everything they know/think into a giant blob of messy writing.] First off, my essay for 24.900. Yeahhhhh.... that was a rough one. Despite starting the required reading a week before it was due instead of a day, I still ended up staying til 6 AM writing it. Thankfully, since I have a 6.042 midterm tomorrow/today, recitation was optional, so I didn't have to wake up til 11:40 AM. F...

Playing Depression Quest

Image
         Before I start my blog today, I will warn you that may or may not be discussion about mental illness, which may be a heavy topic. Proceed at your own discretion.           Yesterday, Grace mentioned Depression Quest  as a game she had to play for her CMS HASS class, among a bunch of other games I don't remember. Depression Quest  is the one name I remember, mostly because the topic of depression is quite a heavy one (especially considering my aspiring major is Course 6-9). I actually ended making my persuasive speech for last semester's HASS class on depression awareness, so you can probably tell that depression (and mental illness in general) is of at least some importance to me.         One of the things the game claimed to have in its full version, however, is a much more surreal presentation of what it feels for somebody with depression, including both change in photo color and statick...
