Because VPN works by diluting responsibility; i.e. in theory there is no problem to confirm that you have connect to a VPN/VPS X and that X made illegal action Y. However, while in case of VPN there are N other people who were also connecte

I hope they will go one step further and finally open-source it.

I don't agree; the core of array paradigm is vectorisation, as started in APL and continuing in Fortran, J, K, lush or R. The idea that it has something to do with matrix algebra is wrong -- MATrix LABoratory is simply an orthogonal story.

You didn't get my example -- it was about how to make a matrix from the results of a non-vectorised function that gets one number and returns a vector (say performs a complex simulation). The problem you've solved has an equally simple impl

Nope; this entity you describe is not a matrix of lists but a single list with dimension, and sapply creates it when mapped function returns list with the same length for all iterations (which is a perfectly consistent behaviour to how sapp

So you also think that mean(iris(iris(:,5)==2,2)) is more intuitive than mean(iris[iris$Species=="versicolor","Sepal.Width"])? Or that constructing matrix by mapping f on 1:10 like M=[] for not_i=1:10 M[:,not_i]=f(n

My personal observation (after 6 years of using and 3 years of teaching R) is that people misunderstand R by skipping the array paradigm part. If you don't get it, others' code looks like magic and either your code is slow and ugly or you s

Actually, Australia is smaller than Europe (in means of the area) -- its 7.7M(km^2) to 10.2M(km^2).

This would require dissecting newborns, so I doubt it. Anyway my point was that it is better to approach strong AI by improving and connecting silicon-based ML methods than to put huge amount of power and effort into imperfect neural abstra

I have a feeling that this is like an attempt to simulate a SOC computer on a quantum physics level based on a blurry microscope image of it in hope to play minesweeper on that. Basic principles (neuron behaviour) are hell of a complex and

_Arbitrary_ SVG is a security/privacy problem -- it may inject JS or exploit quirks in rendering to manipulate site contents, import external images and fonts, or simply be a render bomb. And it is hard to filter out those problems.

The author only advices to use UNIX time to precisely measure time intervals and store precise timestamps; your points are of course valid, but they are not a reason to degrade precise data into human-readable pandemonium.

This also happens organically -- for instance the best IF journal in JCR 2011's statistics & probability group is open access, CC-BY and fully gratis Journal of Statistical Software.

I don't know the details but here in Poland they said in the news that European version of FAA (EASA I think) also grounded 787s; this way both LOT's 787s are grounded, one in US and one in Warsaw. EDIT: Here is the official statement (pl):

In principle R language is equally potent than Mathematica's one (functional+self-modifying), so Mathematica clone can be done in R (and in fact there is a built-in function "D" which calculates derivatives of native expressions symbolicall

I bet in 99% of cases using such structure is a nonsense overhead, and in 85% the code relaying on it can be written without a single heap allocation.

Precisely; hinted, procedural vector graphics are this panacea (see SVG's shape-rendering and media queries). There is significant initial cost to create a library of widgets and icons, but they are perfectly reusable and thus overtake a de

I 100% agree that rescaled bitmap will almost always be an ugly bitmap and certainly needs to be fixed, but IMO it is a crazy idea to fix such problem with manual pixel-wise tuning. This something machines should do while rendering vector i

This is not very surprising because such patterns do emerge in various fluid dynamics experiments; especially rotating bucket (like http://magazine.concordia.ca/2008/fall/features/homer.shtml ) or hydraulic jump (like http://www.evo.ds.mp

It seems this mirror is especially shaped to project the ordinarily reflected image in a reversed way, thus putting an object near it surface will break the illusion and show skewed but normally reflected image.

When you remove steering, both groups simply do statistical modelling. From my observations, the main difference is that stats people make simpler models, test well, but are a victim of mathematical tendency to build on too optimistic assum

I do, like, 40% of searches in my language, so it is still a lot of work. Anyway, language recognition is actually pretty easy nowadays, especially with the amount of data DDG has from crawling -- if they care about foreigners of course.

You're talking about Adaboost; general boosting can use any models and the only idea there is that it adds new model to fix residuals of the current chain. BTW "increasingly abstract representation" is a perfect example of this meaningless

My biggest problem with DDG is that it is so English-centric. I know they have those "regions", but the results from them are much worse than from US region and a need to switch them via settings page every time I change the search language
