I've looked at the reddit threads a bit and it looked to me like a place where discussion was going on and people were trying to help. There is a big difference between sharing a photo and asking if it might contain a suspect and posting a

It's a matter of human beings being treated like cogs in a machine (which is in fact what they are in today's world). The potential of highly intelligent people is wasted by those who are better at extracting value than creating it. This

But the weights will be different, which it seems to me is comparable to saying that the principal components change.

I don't like labeling this type of situation mental illness. That suggests that it's only the individual who is ill. It seems to me that situations like this result from a sick system as much or more than from individual sickness.

But once you know the eigenvectors the eigenvalues (and hence their distribution) are determined, again in the original space. On the other hand if you're talking about the eigenvalues for the whitened data they're all 1. So I'm still not s

Whitening and (full rank) PCA use the same linear transformation except whitening scales the eigenvalues so all axes in the transformed system have unit variance. In other words whitening the data before applying PCA should result in the sa

if you take some physically grounded data and change units, you won't recover different eigenvectors as long as your input data is good. I don't think that's accurate. Consider a set of points distributed along a line in 2D. If you do P

If Tylenol makes Americans less judgemental then it really is a miracle drug.

If you change the units that one of the variables is measured in, it will change all the "principal components"! So what ? The same is true of most machine learning methods including neural networks and SVM's, you just have to use the sa

They used to be very common. Probably around the 486/early Pentium days if memory serves.

What is the opportunity cost of me writing this blog post? ... I could also be sleeping, cooking, at the pub, or any number of things, but weighing up the various trade offs and benefits of these actions ‘like an economist’ is simply not

I doubt regulation plays more than a marginal role here. The truth is that capitalism is not good at creating new technologies, only at increasing adoption of technologies that have already been developed. Innovation on big problems is hard

Unfortunately, the short time spent on each project due to a lack of interest means that the magnitude of the income is far lower than I had hoped for – and realistically, lower than could have been achieved with persistent effort. Wouldn

Yes but real cryptographic functions, like SHA256, are extremely hard to reverse. I doubt writing a crossword solver is an easier solution since that would need to deal with word definitions and is hence a natural language problem.

Probably a hash map from words to definitions along with a list of positions within each definition record. I may post an implementation later if nobody beats me to it but I don't have time right now.

This particular function is easy to reverse though. Using appropriate data structures you can start with the end result and find all possible candidates for the word in polynomial time.

An interesting thing about this is that you can transform the integer factorization problem into SAT quite easily (I have code that does it). The resulting SAT problems seem to be hard to solve for heuristic SAT solvers once you get beyond

Maybe, but it could also mean they're too bright. People whose brains are good at generalizing from data eventually realize that the vast majority of "new technology" in computers is really 40 (or more) year old technology with a new paint

Are there a lot of sites on the web that post opportunities for freelance/contract jobs ? Except for specific sites like elance, this isn't something I've seen much of.

I don't know why not, especially since they also employ many software engineers and IT people.

by tgflynn 14y ago
But in many industries, defense and aerospace in particular, systems engineers are people who integrate multiple technologies to build systems (such as an aircraft or missile). They don't manage computer systems.

There are lots of expensive software products that I may have an occasional need for but not enough to justify purchasing a license. For example : - Microsoft Office - Various (possibly obsolete) versions of Windows - Non-Express versions

It would be nice if someone who knows what this is about were to explain it. It looks potentially interesting but a quick look at the (slow to load) site didn't immediately reveal it's purpose.

Wouldn't those modules be considered part of avionics though ? I got the impression the article was talking about the totality of avionics software run on the spacecraft, perhaps that impression is inaccurate.

They do not have hard realtime requirements If spacecraft avionics doesn't have hard realtime requirements what does ?

I believe industry is full of people solving really hard problems with little financial reward or internal recognition and zero public recognition. I've worked with such people and I've been one myself. It is definitely frustrating to read

Why would the fact that a drug is patented prevent it from being used in clinical trials ? Can't a patented product generally be used as the buyer wishes once it is purchased (subject to other laws of course) ?

I wonder why the linked benchmark site shows g++ to be 27% slower than gcc. Is this just compiling the same C (as subset of C++) program with two different compilers or are they comparing two distinct implementations of the same algorithm
