aet··on Online Algorithms in High-Frequency Trading
You have the wrong question. The question is: What is the optimal market structure? Trying to strike a balance between the benefits of competition and the troubles of market fragmentation. Fragmented markets = HFT + competition. Unified markets = monopoly power + liquidity. You choose...

There are way to identify weak students even when they google all the answers. Base your grades on assignments, tests, projects, presentations, pop quiz, etc.. you will see the pattern.

I'm not a teacher, but I can tell you they already have enough work without having to redo their assignments every year.
aet··on Ask HN: What is “full stack” actually?
An old school example of "full stack" is LAMP: Linux/Apache/MySQL/PHP

Think of Paypal and X.com -- how'd that work out?

aet··on Stretching the “peer reviewed” brand until it snaps
I think the problem is with the publishing culture in some disciplines. For an example of a field in which peer review does not appear to be problematic consider finance/econ. In finance and econ you march you paper around to a number of different conferences. At AFA you even get a discussant that presents a critique after you present your work. After evolving the paper based on feedback from the conference circuit you eventually submit to a journal. At this point your work has been (hopefully) widely circulated in the community and is unlikely to be some piece of crap.

Contrast this with engineering. When you submit to a conference it has to be "new" work and you lose the copyright. It is a one shot deal. So, the benefit of feedback you might get on your work is basically irrelevant because that work in no longer publishable.

aet··on Big, bad Amazon
They are more than just a book store, but they do sell 40% of all new books with no competitor in sight. I can't see how any bookstore can't afford to be online. Even small independent book stores do sales online.

aet··on Xiaomi, Not Apple, Is Changing the Smartphone Industry
Very interesting article. Using Apple in the title in a nice hook, but this should scare manufactures that use Android (Samsung, etc) not Apple. Does competition from Xiamoi have anything to do with Samsung's earnings shortfall?
aet··on Helping my students overcome command-line bullshittery
"A computer scientist specializes in the theory of computation and the design of computational systems." Computer science is about hardware e.g. VLSI. It is a shame that CS undergrads aren't forced to learn a little more about circuits, etc
aet··on Helping my students overcome command-line bullshittery
I imagining a scenario in which I have a team and I have 10% git experts, 90% not -- can I create a system in which they are basically "drop boxing" and the merging etc gets handled automatically or decisioned by an expert? -- Maybe ultimately everyone should just learn git since it isn't that complicated.

aet··on Venezuelans turn to Bitcoins to bypass currency controls
I think it is the efficiency that I didn't consider. As far as I know, gas is roughly 5 cents a gallon.
aet··on Venezuelans turn to Bitcoins to bypass currency controls
Gas is apparently 0.06 cents (USD) a gallon. A gallon of gas provides roughly 30 kW/hr. How much is a kW/hr of electricity in Venezuela? If it is more than 0.002 (USD) a kW/hr you might be better of w/ electric generator. Anyone have any more recent numbers? I see an article from 2013 that says prices in Venezuela are roughly 0.03 cents per kW/hr. Maybe someone can check these calculations. Could have made an error.

Why don't you mine for BC using the super-cheap gas (6 cents a gallon)? (the ultimate insult to environmentalist, such as myself, everywhere)
