It Cannot Be

Spotted this in the corridor outside the Chinese Library when I was heading home on Monday night. Everybody probably knows the efficient markets joke by now - to an economist, the bill can't be real, because someone else would have snagged it if it was.


A theoretical impossibility!


Being a student of the discipline, what else could I have done? I gather others could use the two bucks more, anyhow.

They could, for example, top-up fifty cents, and buy a one chicken plus two veggie nasi padang... whoops, only works if you're a Member of Parliament, otherwise it's S$6. I admit that I would not have sensed anything amiss either, if only because prices at the Business Canteen have remained reasonable, with about S$3 getting your pick of kebab rice, fish and chips or regular old economy rice. However, if that's what meals now cost at coffee shops... how is inflation here 2%?!

Of course, in the grander scheme of things, half-price nasi padang is small potatoes. Unlike the riot, the public reaction to which, it has to be noted, was jarringly muted. Quite astoundingly, I could detect nobody at all even mentioning it directly face-to-face - not students on campus, not aunties on public transport, nobody - which is quite unprecedented for news of this magnitude. I can only attribute it to a collective (sub?)conscious attempt at selective memory blocking - or perhaps heightened sensitivity, given the presence of innocent foreign workers who might be inadvertently affected.

No big surprises in the measures and effects, however - they are already staking out Jurong Point, among other alternatives, while the Little India alcohol ban becomes quasi-permanent (also check off item five, with congregations now frowned upon). Of course, after the six months of no beer and no new riot, it will be concluded that alcohol was the root cause after all. Easy. Next on the list: katanas - which reminds me, I've got to get the box set of Samurai Jack one day. They don't make cartoons like that no more (hey, it's practical)


Wow, Such Report, So New, Much Funding

I was agonizing over my own research, when my intrepid hamster duo approached.

Me: Hi, Messrs Ham and Robo... who appears a little... flatter than the norm.

Mr. Ham: Being sat upon by a five-pound bunny will do that, when you're under one ounce yourself.

Mr. Robo: *shyly* I wondered if you might be so kind as to review this little technical report that we wrote.

Me: "Perturbation Search for Nonlinear Shape Registration"? Sounds familiar... you two didn't actually go and implement the procedure that was suggested last month, did you? Ah... how do I say this - it is fairly trivial, and I gather that the original authors probably knew of it.

Mr. Robo: Bu... But it works perfectly! There were like thirty images in the test dataset that were badly registered, same as the apple image, and the method fixes all of them!

Me: Erm, that follows from how the original method operates. You really didn't have to try it out in practice, to know that it would most likely pan out. *flips through* Though it's a fair enough presentation. Of course, if you are serious about it, perhaps add more experiments, say on 3D objects, and work out a more sophisticated way of searching for the gamma-transformation...

Mr. Ham: Bah, like I told Mr. Robo, it is merely a matter of wiggling it about until it all fits, like when I fixed his computer for him. And he's supposed to be the technology whiz!

Mr. Robo: Um, you forced the GPU chip into the CPU motherboard slot then...

Mr. Ham: *waves a dismissive paw* GPU, CPU, what's the difference? Mr. Ham doesn't sweat the small stuff.

Mr. Robo: ...and actually, that was all Mr. Ham contributed.

Me: In a way, he's right. Many of our best-loved algorithms are rather straightforward when distilled to their essence. Support vector machines are just finding the maximum margin hyperplane in some other space, random forests are just averaging over a large number of slightly-varied decision trees, and the list goes on. There's mucho math involved, but the ideas are surprisingly approachable. If you're looking for "magic", well, research may not be for you.

Mr. Ham: You've got to admit that typing it up in LaTeX automatically lends a modicum of respectability to one's writings, however, compared to plastering it in a blog post.

Me: Meh, fine, whatever. But since when have you become interested in computer science?

Mr. Ham: I thought the firm of H.L. Ham could do with some diversification.

Mr. Robo: *tears welling up* My... my savings! Waahhhh!

Me: You should really do something for him.

Mr. Ham: Fine, fine, I was saving it for the new year, but here goes - Mr. Robo, you're promoted to assistant research assistant, second grade.

Mr. Robo: *perks up* I am?! Yay!

Me: Mr. Robo, you are letting him off way too easily.

Mr. Ham: Which reminds me, sir, I could not in good conscience leave without recommending to buy...

Me: No, don't try to sneak a reference to...

Mr. Ham: Dogecoin! Before I get Mr. Robo to cook Hamcoin up, anyway.


Be brave, good investors


Me: What the heck? Even the meta's gone meta? Argh, might as well throw it out that an intermediary has sprung up for The Coin That Shalt Not Be Named, though it does intrigue with multisignature escrow, with fees only coming into the picture on disputes, unlike the flat-fee model currently popular with traditional banks. There's a lot of space to be explored here.

Mr. Ham: Such wow!
