I think those few days for students to try out new subjects is named "summer break."

Think of it as a commenting or documentation system that's also interpreted by the language. Comments that can never get out of date. If you think that human-readable comments and documentation are not useful... then I'm not going

From DougWebb, explaining why this would be a good thing to do. >> These expressions are the same; they're not meant to strictly indicate order of execution, they're meant to express programmer intent. We can achieve perfect

I'm not aware of a language that allows operator overloading for matrix operations, but denies you access to c.Mul(a,b) or the equivalent when you need it. I find operator overloading pretty crucial for prototyping this sort of algorit

Because surgeons are already workaholics with insane work/life balance issues, perhaps? Same for many other professions.

Isn't this taking a somewhat narrow definition of "the e-mail space"? Slack, Twitter, Facebook, Snapchat, etc. all seem like successful innovations that lots of people use to communicate instead of email.

"Fake Internety money" of course actually translates into real job opportunities in this case.

Kind of an inflammatory title (but from the original article, so not a complaint about HN). "Physicists hope to learn more about physics from the Higgs Boson" seems more accurate. :)

I work on research close to this area -- time series w/ macro applications, but not on these specific models. These specific models are very very important for estimating the effects of monetary policy decisions, forecasting, etc. beca

Small world, his office is the floor below mine :) I think we probably agree then --- but this announcement isn't exactly a sea change in open science and policymaking. This model (or one very close to it) has been available on various

I agree with you, but that's not a decision that can be made unilaterally by professors at the course level without sacrificing _a lot_ of the other content. You're going to cry if you see the current standards of undergraduate sp

This also provides a lot of justification/support for those of us who'd much rather teach (say) macroeconometrics in julia instead of matlab.

I think you'd be surprised. I put "I ran my simulations in Julia, talk to me about it" on a slide at a talk in the spring and was really surprised by who was already using it.

No. A central bank moving at all to Julia is absolutely fucking huge.

As (potentially) one of those professors, I'm going to suggest that if you're posting on HN, you have no idea how little computer experience some of the Econ, engineering, etc. students have. Matlab and other programs like it try

Any effective tutorial is going to gloss over some, potentially lots, of infrequently used confusing edge cases. That's great sometimes. But when I'm trying to understand the infrequent and confusing edge case, a generic tutorial

I have high hopes for Julia, but it's not really competing with Mathematica AFAIK, so I'm not really sure what's behind these claims.

I might be misrembering, but I think that it was assumed for a while that perl would be used for data munging, so there wasn't much effort put into that part of the language. That's being addressed now by packages, and a lot of th

I always recommended ssh until trying to use gitlab for a class I teach to nonprogrammers... and the extra complication over https was immense. Lots of github's users have never used SSH before and those that are comfortable with it

In my anecdotal experience, econ PhD students are a lot more likely to take graduate math classes than cs PhD students. The PhD probability sequence was more or less a standard part of the econometrics course work in my program. Admittedly,

I wouldn't call that view "unfair and offensive to economists," just not super original or useful. There are huge financial and societal rewards to producing "better economics" than we have now (i.e., you'd do

I'd like it to be a bigger part of economics training, but most econ majors have about a year of formal statistics/econometrics as a year of their coursework.

I just meant that an economist would have written differently in a lot of ways orthogonal to the point you were making. I didn't mean it as a value judgement (i.e. that an economist would have written it better), even though my post mi

Generally agree, but "theories ... have mathematical proofs behind them" doesn't distinguish computer science from economics. And I think you'd be surprised at the level of mathematical sophistication of a lot of econ. (

Definitely not by an economist. Statements like > Economics is divided into many schools, in turn leaning neoclassical, heterodox or other are a pretty big tipoff because 1: non "heterodox" economists do not care enough about h

I suspect the math is easier if you reframe the hypothesis to be about the derivatives: adding one more person from either group should have the same marginal effect on outcomes. As you get more observations you get more in a neighborhood o

The connections at a top PhD program are unbelievable too.

Even managers/companies that would be happy for someone to take a few months sabbatical from their job would probably not want to be asked a day or two before the sabbatical would start.
