A month is not a well defined unit. There are four different month units: 28, 29, 30, 31 days. If you do calculations respecting this there will be no problem. Complex numbers and vectors are not a good analogy.
This is a good point. From the article "Once the students were selected, the researchers then administered the Major Field Test in Computer Science, an exam that was developed by the U.S. Educational Testing Service and…

I am not criticizing the study. I am highlighting that the conclusion that the paper arrives at i the correct one: That it warrants large scale studies. This work is a prime candidate for being misrepresented as showing…
The phase 2 study primarily looked at safety. There was no correction for multiple hypothesis testing on the efficacy endpoints. So it seems that the only conclusion that is warranted is that the study shows no adverse…
Basically we can represent any signal as an infinite sum of sinusoids. If you know about Taylor expansion of a function, then you know that the first order term is the most important, then the second and so on. Same…
The first thing I noticed was the ringing, which is an artifact of low-pass filtering so it's a nice opportunity to go into problems with that kind of filtering. Other than that I think it was an ok teaser that gives an…
It is from Bellman, Held and Karp [0] and has O*(2^n) complexity for both space and time. It is quite simple and based on the idea that "Every subpath of a path of minimum distance is itself of minimum distance." [0]…
As with a lot of "simple" math, the trick is to actually write it down and calculate it, because our intuition (at least for some of us) is often not the best when it comes to this kind of calculation. In this case we…
Forcing a nation is what war is about, and it rarely works out very well. Negotiation is about finding a solution to a problem that leaves all parties better off if they follow the solution than if they don't. It is not…
There is a lot of stuff the human eye cant see that is very interesting. One of the challenges in medical imaging is getting accurate labelling of images. For many labellings we see large inter- and intra-observer…
> It is not a question of if but when You can say that about almost anything, and the world is still full of factory workers. As a PhD student in medical imaging, you must also know that getting fully automating…
Stating it as "thousands of patient images a day" is misleading. It would be the same as saying you inspected "thousands of parts each day". As the radiologist further down notes, CT scans contains many slices. While…
I am curious. Could you highlight some of the technical problems with Firefox?
Yes it is obviously an error by the doctor and the pharmacists, no one is saying otherwise. The whole point of the article is to investigate how this error occurred. We live in a world where these errors happens all the…
That is a good question, and one we should discuss more actively, because if it can go wrong it will go wrong. What happens when an over eager politician learns that "we can predict with X% accuracy if a person will do…
I think it is nicer if you just link to the arxiv page instead of directly to the pdf. Then I can read the abstract before downloading it. http://arxiv.org/abs/1503.02401
I think the points are good, but I am not very happy about this statement "When dealing with small amounts of data, it’s reasonable to try as many algorithms as possible and to pick the best one since the cost of…
A specific critique raised in the press release from IARC is that the study has an "emphasis on very rare cancers (e.g. osteosarcoma, medulloblastoma) that together make only a small contribution to the total cancer…
Yes I can do basic arithmetic. My point is that the ratio is easy to interpret, the program ran 6.36 times faster. The only reason I can think of for giving a percentage is to make it sound more impressive.
That is nice illustration of premature optimization. Instead of thinking "Lets parallelize", one should measure and find out what causes performance problems. Should one choose to go down the parallel path, it's a good…
In general I think the distinction between physical, neurological and psychological is peculiar. It suggests that the mind is not physical but a metaphysical entity that can be be analysed separately from the body and…
I think that programmers reasons for choosing a specific language are as varied as the languages. Personally I like programming in C++ because the typesystem and abstraction mechanisms allows me to write reasonably…
I dont like this paper. It makes statements based on references to opinion style articles. F.ex "in practice, run-time type errors in deployed programs are exceedingly rare [TW07]." If we look at [TW07] they state that…
