This does happen. I've had paper reviewers request results with an appropriately selected uninformative prior: https://en.wikipedia.org/wiki/Jeffreys_prior Typically, if you are practitioner in the field, it is no

Probably broader than just CS -- wouldn't be surprised if the teams include physicists, engineers, computational scientists, etc.

Very interesting. Would be a truly great milestone in history to have an algorithm that can beat humans at Go. Far more impressive than chess, IMO.

I had a similar experience to rubidium. (Texas Ph.d., here, although in computational science, not a vile experimentalist ;) ) I've seldom seen an argument suggesting that the pay between Ph.d. and masters is substantial, or even advan

This was fascinating and greatly informative. As you said, the authors were not afraid to show the real warts and bleeding edge, as a good scientist should. Thanks for the link.

Generally agree with the sentiment, but I think the line is fuzzy along the periphery. For instance, economics has, I would claim, far weaker levels of model validation than engineering fields, but often is presented as a hard or 'clos

I dislike prepending data as a title, because it was already implicit to any scientific discipline.

I find it surprising they implied Overdeck is a superior mathematician to Tao. Winning the fields medal is a public award, based on his excellent papers and results. Contrast this with some event in Tribeca the article does not even provide

Why was this voted down? cheald presents a reasonable argument. Certainly no ad-hominem attacks. Thimothy then presents a rebuttal with reasonable counter-claims. I find both points of view interesting and contributing to the discussion. Th

Scientific software should absolutely, always be verified through regression and unit tests. Anything less is non-negotiable. In a decade of work in hpc and computational science, I have very seldom found looking at the code to be a useful

For what problems? General statements like this are hard to back up, especially in the wild world of numerical linear algebra. From my experience, there are currently no good distributed-memory open source sparse-direct solvers. No good dis

Eigen is header only and heavily templated, which certainly keeps the source down. However, SLOC is a poor metric for the quality of a codebase, especially scientific ones. I've certainly found many instances where longer line counts a
