I wonder if cheating could be entirely solved with machine learning like TrueSkill that matches you with people with similar performance. Then matching cheaters with cheaters is almost guaranteed to happen, and a bad player cheating a littl

Giving students close access to a program that evaluates essays many times would be the worst possible thing to do. People are generally very good at adapting to systems, and the algorithm would break down pretty quickly as people find out

It's actually a more subtle problem: if you test a radical redesign, there's a higher likelihood it will fail even if a subsequent series of small changes to it would have produced something better, just because the incumbent is so well opt

By non-intrusive I meant that I have no idea what kind of ML is really going on behind the scenes. In this sense it's very different from interacting with, say, Netflix's recommender, or youtube's ad predictor (a friend "liked" a vodka ad o

As a recent daily user, prismatic is awesome. The way they leverage twitter is pretty interesting, mixing in "endorsements" to articles from both people close to you, famous people, and random people, in a way that keeps it interesting. The

The population is strongly clustered on some big cities in the coast, the roads aren't super safe, and the terrain around the coastline is not flat, so it's probably just cheaper to lay them out in the ocean.

Jorge Luis Borges in a book of memoirs told that when he worked in the library in Buenos Aires as a clerk one day one of his colleagues barged into his office to show him an encyclopedia (or list of famous people, or something like that) th

I don't think you can answer these questions with theorems or experiments about models of computation (which is how TCS answers questions), so I don't think they are TCS questions. They are, however, central questions in the philosophy of c

As an owner of a shattered iPod and a pristine (but much more aggressively dropped) nexus S, the solution is really curved screens with protective plastic on the edges.

The title is kind of a bait. The article is an interesting-enough discussion of Amdahl's law and how it can limit efforts to parallelize stuff at google.

Regarding [1], each bus company has a different color. The companies won different government contracts for different parts of the city, so the east side is roughly red, the south blue, the north-west green, etc.

This suggests that it's worthwhile to educate the young in not just doing the same things with computers that everybody knows how to do (Office-style and web browsing) but inculcating habits (versioning, say) which will make life much easie

This is an interesting question. I'd say it's a mix of technical and social factors. Technically it's a solid abstraction (versioned directories), it's ridiculously fast (specially when compared to most alternatives at the time, even local

The problem is more complex. Some errors will damage the scientific conclusions, others will show up as fractions of a percentage point inside a much larger confidence interval, and will ultimately not matter much. In machine learning resea

The worst thing is many investors who hold shares of one company also holds shares of the competitor, and hence they are spending money wildly to make their portfolio as a whole worth less.

Which is a pity when you think about how crappy and unfinished the unity UI in ubuntu 11.04 is. In years this is the first time I've stopped using a standard ubuntu (now I'm using Gnome 3, which is almost as bad).

If all providers start actively trying to not touch these ads the expected incentive of posting them will go down; hopefully enough so that they end up having to negotiate directly with websites or something like this.

Indeed, I agree. I just hope they follow through and use this case as a precedent to shut down or severely harm the other ad networks that do essentially the same thing.
