The article is gushing with superlatives and amazing anecdotes. For instance, "The results have been excellent. One autistic child moved up a phenomenal amount and is proving to be a highly able mathematician." Is it really the case that

It was very interesting to read the hierarchy. I hadn't seen it before. In some case it may be more statistical than universal. For instance, even in the case of the old canvas fishing hat, what if it is both "battered" and "large"? Do w

The feature where you display a word cloud over a link seems slow enough that users might find it annoying to watch it load. Some word clouds are made of clickable tags. When users try to click, but cannot, they may not like your clouds as

This is an outstanding, well-written article about how business management often falls victim to faddish theories. It is long, but enjoyable and well worth the read. My favourite quote: "Knowledge, by its very nature, must be intelligible,

Yes, "preloading the delta between the server clock and the client clock" is what I had in mind when I wrote "synchronized to the same clock". That is, synchronized to the server clock.

Is this thing surfacing again? It was fashionable several years ago for Professional Engineering Societies to advocate for a P.Eng. designation requirement for all Software Engineers. I thought the idea had since died out.

How about every second year CS student write a URL shortening service on the web. Then we should have lots of them. Then, how about every third year CS student write a paper discussing why URL shortening services are a bad thing. Maybe fou

First, you need each instance of your running web app to be synchronized to the same clock, so they can make events occur at the same time. Second, it would probably be best to upload your images from your server to your 1,000 clients befor

Here is another clear difference between industry and academia: When your million-dollar grant gets funded, you buy your grad students a beer. When your million-dollar contract gets signed, you buy yourself a car.

I think the degree of supportiveness among peers varies considerably across disciplines. Peers in some fields are extremely competitive and hyper-critical of each other, despite being capable researchers, and they unwittingly undermine the

Your boss wants your success to serve his agenda. Try being successful in a way that makes your boss look bad, and you'll discover he isn't the least bit interested in your "success".

very cool. Do you have any demos that show explicitly how Processing.js can communicate with the document loaded in the browser, ... for instance, to enter a value on a form and then submit the form? This would open up new creative ways

I was taught this method of calculating a square root by hand when I was a child in public school. I have since been surprised by the number of people my own age who were never taught. Since many Canadian high schools only teach "pre-Calcu

Your deniability will not be "plausible" if the two-message feature you described is in the software documentation. At least with disk encryption, you could claim the rest of the disk is "unused". With email, your encrypted message would b

Amazon's Mechanical Turk (mturk.com) would be one place for you to look.

Thanks for this link. It makes an explicit link to similar demographics for "ESP" games.

The Calorie Tracking example (in the blog posting) illustrates that Mechanical Turk relies heavily on tremendous inequities in wealth. A rich, fat, lazy person snaps a picture of his lavish meal with a fancy iPhone, and rather than take a b

Actually for small enough matrices (as you might imagine) the matrix multiplication in PHP is not horribly slow.

Thanks, I appreciate the link to Thrift. ... and I agree on the responsivity comment. I guess I'll look into setting up a daemon to my math in the background.

I like the lottery ticket analogy some people have made, but here is my twist. My service costs $X per month. So if you like it, you'll want to pay $X. ... But for a just this month, there is a 1/10 chance your $X will get you the service

Are you a native English speaker?? Both are correct. They are different forms of past tense, with different meanings. "we defined ..." The "simple past" is used for recounting past events, as when telling a story. "we have defined ..." The
