From Pierre Elliott Trudeau H.S., Olympiads School, Canadian Computing Olympiad, University of Waterloo AboutRepresented Dmojistan at IOI 2017. Fun fact: The DMOJ logo isn't symmetrical. This is obvious in the logo below. This is not obvious when the logo is tiny (like the logo in the topright of every DMOJ page).
Math contest lottery winner (AMC 10B 2015). Just wanted to say that there is a Userscript thing when you edit your profile. Use it to prank someone. After you're done, make sure to give them this link and tell them to erase the Userscript.
Fun facts123*542=66666 O(n!) = O((n/e)^n) by Stirling's approximation. Ｇｏｏｄ ｆｏｎｔ。 I still play osu! (mostly the mania mode) Changed my password due to Joey, don't trust him with your stuff. There was another person in my school with my same name and grade. Points become exponentially annoying after 3000p or 200pp. DM::OJ doesn't support multithreading. Programming path:
(Olympiads teacher) Some of my submissionsGood submission to DMPG '15 S3  Zen Garden (I wrote a program to do this). Some of other people's submissionsSecond best comment (problem) (I can't remember that Thornhill banner anymore) Longer compilation error (problem) Unusual problem pagesUnusual facts about DM::OJdmoj has two chats: ancient dmoj chat and Slack (in the footer) dmoj has a neglected page (now deleted). dmoj has an editorial page that is very hard to find. This is strange because I don't think other pages link to it. global_smurf's password is brucedontputmeintothepassword (why, kobortor?) (someone changed it for some reason) :( (I think r3mark changed it) Unusual pages on the internetLoop. (doesn't work anymore) :( time.is isup.me repl.it HTML to markdown. (Note: poor quality converter) Markdown to visual. (Note: this website's markdown can parse LaTeX) Math
$\frac d{dx}f(x)^{g(x)}$
