I like it. How do you enter a tab character in the test string without losing focus of the text field? When I start typing the regex, the cheatsheet gets pushed below the visible part of the page as the "explanation" section expan

I just searched for a few different mutations of the phrase "background transparency" in their bugzilla and didn't see any. I was expecting this to be a case of an end user not taking the time to see if their issue was already in the bug tr

Shameless plug for a genetic algorithm based trading strategy app I made a while ago. It generates a bunch of strategies with good scores and then the UI let's you pick the one's you actually want to use. The second video is the demo: http

Fascinating to see Automated Design (optimization software applied to product development) in the wild. Some of the more interesting applications deal with situations where the definition of 'optimal' is based on a changing data set, like t

I still find it hard to believe the people in the top 10 aren't all at the theoretical limit of predictive accuracy with their final order being determined by nuances in the experimental design (things like how the raw data was collected).

If I create 1000 predictive models, with random parameter settings, some of those models will outperform others. In fact, the accuracy rankings of the models given a single hold-out validation set will form their own distribution. It is dif

This is currently #1 on the frontpage. I have to assume it got there by skeezy methods like those described in the article.

I don't think this scenario could play out that way. - Facebook profiles can be made inaccessible to non-friends. People who post pictures of themselves naked and using drugs use this feature. - The hypothetical conclusions drawn are only p

IMO, this experiment would have worked on LinkedIn. The targeted ads I see when I'm in there are way applicable to the "professional me" than FB or Google ads. LinkedIn just makes more sense for a B2B marketing campaign. I'm sure the number

Why can't you set up a virtual server with your default setting and applications and then clone it? (I'm really asking for more details, not making a suggestion in the form of a question.) You also get little benefits like having your .vimr

It's worth pointing out that Airbus has a large presence in France and Ocaml is from a French research institution (INRIA). I highly doubt that's a coincidence. Disclosure: Ocaml is my favorite language by far.

But the point is that if you drive to a gas station, there is gas to buy. Imagine you drive a delivery truck, the price of gas goes up, and you go out of business. It means you didn't have a profitable enough business to handle the reality

I think there will be a day when this will work. But right now my concerns would be: 1) The people looking for outside help probably don't have ANY model, so baselines are difficult. (I use synthetic baselines like just predicting the avera

The more painful part of the article is the subtext that a startup's "product" is by definition something built in a few months with RoR or Django. For all the talk of how much angel and V.C. money is available for young companies, it's not

While I appreciate the sentiment, it's not exactly a fair comparison. The first government rocket launches surely had cost overruns. But were the most recent shuttle launches vastly over-budget? Launching a satellite these days is a relativ

I do this a lot, particularly with projects that use a database that might be hard to configure (and the configuration isn't fully scripted). Just get the development version of the DB right once, and then make a copy of the machine in case
