The Manxome Foe

At work, for the past week or so, I've been wrestling with a complicated-ish thing, born of a conversation over lunch about something completely different, and taking me deep into some statistics and algebra that I don't really understand (yet). It's awesome.

But (more than once), I've been explaining the thing to someone, and had them offer helpful advice: "Isn't this problem basically [this simpler thing]?" My response has consistently been along the lines of "No, of course not! Can't you see that it's obviously more complicated than that?" I even had a version of this exchange with myself recently, where I thought for a moment that it was actually trivial after all, and then (with some relief) reminded myself that it was, in fact, hard. Whew, what a relief.


...except that, if the point was actually to solve problems in the world, that's entirely the wrong attitude to take. This problem either:

  • actually isn't complex, in which case rooting for it to be harder is pretty useless
  • actually is complex, in which case rooting for it to be even harder is pretty useless

This isn't academia, where pretending that the problem you've got a solution to is actually Really Quite Hard is a good thing, since you can then wow people by solving it. I'd like to think that I'm in the business of actually solving problems -- and to do that, I can't take sides on whether it's hard or easy. Either way, the only thing to be done is to do it. If it's easy, do it fast and get something harder.

Today's Quote: Fallibility

Today's quote comes from a talk about programming languages:

"If you're ever writing code to loop over the indices of an array, just assume there's a bug in it somewhere."

(In particular, we were discussing pitfalls of imperative languages, but that's not at all important to what I'm trying to talk about, so ignore this sentence if you didn't understand it.)

Okay, so it's not quite true; I've reached the point in my programming career where, upon needing to write array-indexing code, I am still forced to stop, ask myself what I want to do, and then tell the computer to do it -- but at least I usually get it right that first time. Even so, there are certainly other areas of my life where I could benefit by applying similar logic:

  • If you're ever planning to be on time to a class/meeting/event, just assume that you're going to be ten minutes late.
  • If you're ever planning your time around the deadline for an assignment, just assume that you're going to be working up to literally the last minute.
  • If you're ever coming up with a password, encryption key, or other important string of characters to remember, just assume you're going to forget it tomorrow.
  • If you're ever reading a book before bed, just assume you're going to read at least an hour later than you expected.
  • If you're ever planning to take a small nap and get back to work, just assume it's not going to happen.

The common factor here seems to be "There are some things you're really chronically bad at planning; you should stop assuming that you're going to be

Necessary, True...

Just a short post today, dumping something that I found interesting out of my brain and into plaintext.

Today, I had someone pull me aside and ask me if I was alright; several people had noticed that I was really worked up about something the other day, to the point of getting angry at one of my coworkers.

It took me a few seconds to figure out what he was talking about, and when I did, I laughed a little. "Oh, Lucian and I go way back; we've been roommates for two years now. We're in the habit of giving each other a hard time; there's nothing wrong."


Afterward, I realized what I should have said -- something like: "Oh. I understand what it might have looked like, but actually everything's okay. We've been roommates for two years now, and I was just giving him a hard time."

The crucial difference: If someone comes to you concerned that there might be a problem, first let them know unambiguously whether there is, in fact, an issue, and then explain. If you put the explanation before the verdict, they'll spend the entire time parsing through what you're saying, trying to determine whether it makes the problem better or worse, before you give them the bottom line at the end. They'll be distracted enough to miss most of what you actually say, and then they'll be forced to change mental gears at the end from whatever conclusions they had dug into to the conclusion you then sprung on them.

The principle, I think, generalizes. If you're trying to tell someone something important (either in conversation, or, as I've found

Whose Voice? Whose Guide?

nb:The Q Guide is a Harvard-run course rating service. It has its roots in the student-run "Confi Guide", published by the Crimson as far back as 1925. The Confi Guide, however, was eclipsed by the Harvard-run CUE (Committee on Undergraduate Education) reports published from 1975 onwards. In 2005, the "CUE Guide" was renamed the "Q Guide", and moved to an online-only format. Today, the Q website bills itself as "Your Voice, Your Guide".

Much has already been said about the choice to hide important course evaluation data from students (Crimson article), and I won't try to rehash in full what others have said so eloquently. Instead, I'll try to bring to the surface some of the most salient points, and add a few of my own.


First, it's been said (and satirized by Satire V) that Dean Harris did a fine job of (trying to) bury the lede on the whole matter. After all, the change to the Q was announced in sentence 16 of 21 in an email titled "Pre-Term Planning for Fall 2014":

Now, unless the the Dean was attempting to imply that we should be planning for Fall 2014 by scoping out courses now, before difficulty ratings go away forever, one has to question the reason behind revealing a crucial change in student resources (which, as the Crimson reports, has been decided since last September) in the middle of an email about a weeks-away optional survey to a group of students who have already left campus for the summer.


Or perhaps, one need not. I'm not sure that anyone except University spokespeople would be willing to argue that Dean Harris just happened to send

Blogosphere Roundup: Q Difficulty Ratings

I'm planning to compose a much longer post on the recent announcement that the Harvard Q Guide will no longer report course difficulty ratings, but in the mean time, I've rounded up a few of the insightful writers I've found around the web, with excerpts and links through to the full sources.

The Harvard Crimson: Q Guide Will No Longer Display Difficulty Score, Harris Says

A straight news piece, the Crimson article is noteworthy for including several quotes from professors defending the change:

Richard F. Thomas (Prof. Classics)

"[Difficulty ratings] could create an impulse in the instructor to make the course easier in order to attract students."

Mark C. Elliott (Prof. Chinese History)

"[Difficulty rating] is not really the most important thing about a class."

"One hopes that after everything that our students have done up to the time they get admitted to Harvard ... they recognize the value in a challenging curriculum and in taking courses that may not be an easy A, but will add in some way to their intellectual enrichment or development."

Ore Babarinsa '15 (comment on the Crimson article)

For once, sense is spoken in the comments section of the Crimson; my friend and classmate Ore speaks to a student perspective on the necessity of difficulty ratings:

I'm sorry, but the stated rationale given is completely disconnected from any understanding of how, or why many students desperately need that difficulty rating for courses on the Q quide. I've been in the hospital because of having too much academic work on my plate at Harvard, and I think the administrators need to understand that students need to be able to adequately balance the difficulty of

Oh, say...

A year ago, the school (and the city) was just getting off lockdown after the manhunt for the marathon bombing suspect(s). And looking backward, there's a few things I remember quite clearly:

  • the spreadsheet of students offering couch space, spare beds, and sleeping bags to 'stranded' students unsure if it was safe to be crossing campus
  • the Dining Services workers who crossed a city on lockdown (by bike, as I recall) to come in to work, and the students who volunteered to work the dining hall with them
  • the pre-frosh who came to Visitas Weekend despite its cancellation (including mine!), and the hosts who did everything they could to make their stay worth its while (in the fall, the school would announce record yield numbers...)
  • the sudden, temporary freedom from work -- afterward, a friend would recall "I've never felt so free as that day we were trapped inside!" I'm not sure what this says about Harvard.
    But there's one thing in particular about what whole bizarre half-week that I'm unlikely to forget, probably ever:

The day that the freshman dining hall, Annenberg, was reopened, someone proposed an idea which caught on pretty much immediately -- at 6pm, in Annenberg, we'd gather as a community to sing The Star-Spangled Banner. It was one of those things, I think, that a lot of us needed, and it just seemed like the right thing to do on that Tuesday night.

There's a scene in Casablanca where the a cafe of Frechmen rise together in La Marseillaise to drown out a handful of rowdy Germans singing Die Wacht am Rhein.

It's a tearjerking moment, and the first (and second, and
