Honestly, the only way to understand regression is to study something like Mccullagh & Nelders book. Anything else and you are going to have a very hard time really being useful without misinterpreting the results. There are some real s

We've been using phantomjs, but it has it's issues too. I'm not sure there is a good solution anywhere in the open source world unfortunately - and tools like prince are expensive.

Just so you are aware, flying saucer while nice when you first use it has tonnes of bugs and isn't really being developed these days. You'll find yourself more and more diving into the code because the output is substandard. We used it for

This was our assignment for an AI class many years ago - take USDA and a GA with constraints set by users to generate meal plans. I remember being told to eat a kilo of salt :)

The point is that it shouldn't matter how the person chooses to put their thoughts into the world, they are their thoughts not yours. If they choose to do a private performance (a concert) and it gets pirated, that's not much different then

I completely agree - technically. If we invent a technology that allows us to read thoughts, should you be allowed to read them without the thinkers permission? The thinker still has their thoughts. What about disseminate them via torrents?

Given a real world problem, algorithms or the mathematics behind it do not provide insight on their own. The only value knowledge of the algorithms provide is a general understanding of the ways in which you can approach a problem. If you c

That's my point. Algorithms are the domain knowledge of cs.

It wasn't this. The example was trying to show that a lack of knowledge can be catastrophic in terms of productivity for even the gurus. He spent more than six months on this particular problem and if he had known more math (very typical of

We once hired a guy with PhD in computer science & he was a (great) lecturer & researcher for many years. We got him to do some "complicated stuff". I'm not going to go further into the details in case he recognises this. After he l

I used to love data mining. Then I formally learned statistics, causal inference, mcmc and other similar methods. I was amazed at how poor the computer science was for anything outside of computer science problems (i.e. search, collaborativ

I find it hard to understand how writing open source software has a strong value proposition for someone who isn't worried about "getting the next job" or "looking good in front of peers". For me, I believe the best use of those extra hours

With your claimed grades and intellect you could obtain scholarships to almost anywhere of your choosing, fully paid fees + stipend, to work with the greatest minds in your field. Oxford, Cambridge... the world is your oyster. So it's a com

I still find it weird that people charge an hourly rate. My company has been doing fixed price projects, with changing scope, guaranteed bug fixes & payment on delivery for the last eight years. We regularly beat out the "big boys" and

I disagree. He makes two unsupported claims that reek of cargo-culting: "1. The optimal wake feature reduces daytime grogginess only in the sense that it puts you in a better mood in the morning. 2. Yes it is very unlikely to have adverse

What is the confidence interval for the size of the effect that wakemate produces on percieved grogginess vs waking without wakemate? What is the size of the effect in the research?

1) I would disagree. The definition of polymath is someone who is an expert at orthogonal subjects. Your definition of expert seems to be slightly lower than mine. My definition would be someone who could give a lecture to other experts in

I often help (good) researchers with experimental design and statistical analysis of quasi-experimental data, and it's shocking how little they understand. It pains me to think how much waste there is in science at the moment because the re

Is there any data that supports this blog posts contention that the best developers are in the UK on tier 1 visa's? If this were true, surely a large portion of the successful uk startups should be founded by tier-1 recipients?

Knowledge is valuable. Everyone knows it. But very few are actually delivering knowledge. Take a look at the "web dashboard" on dataspora's page. Does that "deliver knowledge" or is it a bunch of charts that the people on the ground won't u

I've looked at matplotlib but still think it's ugly by default. Compare to: http://www.texample.net/tikz/examples/weather-stations-data/ http://www.texample.net/tikz/examples/rna-codons-table/ The beauty of tex font's + vector graphics

I have used R/ggplot for a long time now, and it's exceedingly difficult to produce beautiful visualizations. The only thing that makes tufte-quality visualizations in my experience is hand-building your graphs in tikz. The graphs you linke

No offence but discussing the most recent/interesting paper you have read shouldn't be a tricky question.

I simply give them a call and ask them what the most interesting papers they have read over the last year are. Without any forewarning of course. People who are passionate about things know their stuff; and it's not from blog posts or forum
