HS Day 25: Half a Day Off
I received news this morning that my grandmother, Lila Rhen, had passed away around 5:30 a.m.. Hacker School was deserted this morning – a lot of people were at a Git tutorial somewhere else in the city, so morning meetings were skipped entirely. I spent a few hours chatting with Daniel from Lawrence, and writing…

Lila Emma Maria Rhen
I have not yet attended a funeral. When my mother’s mother died, not only had she been in an advanced state of Parkinson’s disease for most of my life. I was in the middle of school, and since I wasn’t particularly close to her, I ended up not attending the funeral. I didn’t have many…

HS Day 24: Early to Rise
Woke up this morning at 6am, which was only three hours after I finally fell asleep around 3am. It’s not that I’m trying to stay up super late – I blame caffeine, boredom, and the bright light of my computer screen. I was up playing and watching StarCraft and sketching in my new sketchbook. I…

HS Day 23: Walking Around Brooklyn
Woke up around noon and walked down to the Staples, where I had a delivery waiting in an Amazon Locker. Locker is pretty sweet – you walk up, put in your code, and one of the many doors pops open to reveal your delivery. Very easy, and way more secure than having the delivery left…

HS Day 22: Natural History
Short post today, because I am lacking motivation for some reason. My dad and I spent the afternoon today at the Museum of Natural History in Washington D.C.. We ate lunch at the museum, and wandered around the exhibits. Some highlights: – Walked through a genome exhibit. At the end, they have you write down…

HS Day 21: Washington D.C.
Thursday night I arrived in Washington D.C., at Union Station, around midnight. My dad met me at the terminal, and we drove from there to our hotel in Chantilly, VA. I’m still getting used to the idea of doing things in more than one state on a given day. The west is really big you…

HS Day 20: Sleeping In (Again)
I seem to have a problem with Thursdays – I woke up around 1pm today and didn’t get in to Hacker School until 2:30. I had planned on actually being social and joining some people for lunch today as well, which I was sad to miss. Nobody in particular, but I’ve been eating a lot…

A Fix for Ultimate Tic-Tac-Toe?
A few days ago, Ben Orlin of mathwithbaddrawings.com posted Ultimate Tic-Tac-Toe, which described a nested game of Tic-Tac-Toe – In lieu of describing the game again, I’ll direct you to his post if you haven’t already read it. The problem with UTTT is thus: the Orlin Gambit is too strong, and Ben admits it in his later…

LACE: Latency-Aware Collision Engine in Javascript
Code for this is at https://github.com/ertyseidel/collisions Motivation In a multiplayer game, it is useful to be able to do collision detection on the server, to ensure that your players aren’t cheating or moving incorrectly. When we take latency into account, and the other myriad problems that can come about when we deal with packets, this problem…

HS Day 19: Nearing Success. Also, Internet.
Started the day on time at Hacker School, in a new morning meeting group: Russel, named after Steve Russell, the inventor of Spacewar!, one of the first videogames. He also did some of the first implementations of LISP, way back in the day. Thomas, Nina, Carl, Tom, and George will be the new faces I…
