Bounded-Error Log

original sillier post Note on notation: I’m going to use \(\text{Stab}(x)\) instead of \(G_x\) for the stabilizer subgroup and \(\text{Cl}(x)\) instead of \(^Gx\) for the conjugacy classes.

original sillier post Note on notation: to be maximally clear, I have bolded all my vectors and put tiny arrows on them.

A PSYCHOLOGICAL TIP Whenever you’re called on to make up your mind, and you’re hampered by not having any, the best way to solve the dilemma, you’ll find, is simply by spinning a penny.

CLICKBAIT PERSONALITY TEST THAT YOU CAN DO WITHOUT SOLVING THE PUZZLE: What do you see in the puzzle image below?

5:27 PM phenomist: do you use gridderface to make pretty puzzles?

These are the thoughts that sometimes keep me awake at night.

Well, it’s been over a week, which is a long time for blog posts to be delayed after the event they’re documenting in probably all of the world except my blog.

Okay.

Some notes.

As per item 3 of 50: InfiniteLooper version Well, there are better memory-triggering songs but I think this pretty much sums up how I feel about blogging right now (possibly including the very act of choosing that song.)

This post, or most of it, was published password-protected once because… well, I explain that below.

This post was written in Traditional Mandarin Chinese for my fellow competitive programmers in Taiwan.

Well, there had to be something here.

original sillier post The “Extreme Value Theorem”, according to my old calculus textbook (Larson, Hostetler, Edwards, 8th ed.), is “A continuous function defined on a closed interval attains a minimum and a maximum on the interval.”

Continuing the porting of stuff from betaveros.stash, and adding more stuff.

Miscellaneous observations that didn’t make it into a compelling narrative, sometimes because I have forgotten exactly when they happened, sometimes because I only remembered when they happened after blogging about it, sometimes because it just seemed too…

No, I didn’t forget.

Shamelessly getting unfinished business out of the way.

I started trying to sleep at 9 the night before the contest, tossed and turned in bed until 10, then fell asleep and got up at 3:35 in the morning.

Okay, I guess it was really naïve of me to suppose that I could get any considerable amount of blogging done before the IOI ended.

Yes, I know day 1 of the contest already ended and is probably a more interesting topic to blog about, but I finished writing this last night just before the internet was cut off to quarantine the contestants from the leaders, who received the problems and

Indexing debates are boring.

Late post.

After the first stage of selection camp, I was very nervous because I was fifth place in a selection sequence that would finally result in a team of four.

As requested, a puzzle post!

First Google Code Jam!

First, I got worked up about the test.

Random video!

I did it!

Note from the future, 2017-11-25: I am fairly unhappy with this rant as it stands — it makes many points I still agree with, but it just sounds sooo pretentious — but it is one of very few posts to actually receive a link from an external post I’m aware o…

Edit 11/19 7:23 AM UTC+8: Fixed some transcription errors on right: R4C17 is D instead of N, and R15C17 is G instead of E.

“I like fantasy books!

I’m extremely satisfied — a little incredulous, in fact — with how this puzzle came out. chaotic_iak labels it the “most ridiculous fillomino ever in history”.

I couldn’t remember how long it had been since we entered the ninth floor.

Oops, I forgot the “puzzles” category was semi-reserved for puzzles I constructed/wrote, because among other things an LMI bot is following it.

Funny, I go on a trip to Penghu followed by a four-day science camp and also get dragged into drawing classes and some sort of movie advising joint, and this is what I decide to blog about.

Isn’t it weird to suddenly talk about this topic?

Parts of this (a majority of questions, I hope) are intended as satire.

“I have been told that any encryption becomes safer if the underlying algorithm is maximally obscured, what is most conveniently done by coding it in Haskell.” – rankk Functional programming is terribly addicting!

So, I somehow managed to get 25 points all by myself in MUMS Puzzle Hunt 2013.

I survived midterms.

because my title needs to mean something.

This is beautiful.

Yeah, and there’s this. chaotic_iak rejected this variant for his February sequence in order to get consistent 7x7 dimensions, so I made one.

Google just announced it’s shutting down Google Reader in three and a half months… I am participating in the friendly Reddit DDoS-hug of all the alternatives (list, but scroll around in the thread for a few more).

Yay crazy hybrids!

So, what have I been doing with programming recently?

Yay?
