Could someone more knowledgeable about nuclear physics than I am comment on the safety aspects of the positive void coefficient of the CANDU design? If the water boils, the reaction could run away. That said, the fact that a CANDU runs on u

You have an interesting approach: more or less a wrapper function around the original API^h^h^hUI. It has the advantage of preserving the—presumably verified, and maybe even certified—safety protocols. This technique might have application

I get in trouble regularly with my wife because I've been trained my whole life to think in a particular way, and that's not how other humans are wired: if (a) { b; } if (c) { d; } versus

How can you tell that two clocks are 22 nanoseconds apart? If the clocks are in the same room and you have a fast oscilloscope at hand, it's easy. If the clocks are more than about 6 metres apart, it really is impossible.

The formatter ate your indentation. Is this what you meant? So this is allowed: if (foo) bar(); baz() But this isn't: if (foo) bar(); baz() And this isn't: if (foo) bar(); baz()

In the beginning, the red graph f is a square wave. It's a little lumpy, because it was made by adding together a bunch of different sine waves of different frequencies and amplitudes (by the way, that slight overshoot/undershoo

Sure, in special cases; and it's an important lesson for students to learn: that in small sizes, theoretically impossible problems (in the general case) are perfectly well attackable by brute force enumeration, and it may be the right

Pedantic is putting the braces in even where they're optional, simply because it avoids problems later on. Pedantic is using Yoda conditionals [1] in C because it enables lvalue checking in the compiler. Pedantic is checking return cod

Designing and building a CPU from scratch is still possible; in fact it's easier now (using an FPGA and a hardware design language) than it was a few years ago (using 7400-series TTL chips and wire wrap). It's old, but I highly re

Some registrars, particularly Network Solutions, offer poor support for DNSSEC records, or anything beyond A and CNAME records really. For a long time it was officially unsupported; lately there is a footnote at the bottom of the advanced D

Nice hack. I can see this being useful in places where space is constrained, such as embedded user interfaces. The implementation in CSS is also interesting. Upvoted to try to get it to the attention of others.

This story reads like a chapter from Cryptonomicon . I really wonder if Neal Stephenson was inspired by it; actually, some of his other short works are set partly or mostly in the Philippines [1] [2]. [1] "Mother Earth Motherboard&quo

We can eliminate the paste by using sed's hold buffer, but it costs another regexp to get rid of the spurious newline: sed -e "h;s/./x/g;G;s/\n/\t/g" list.txt | sort | cut -f2

Sorting by length is an interesting programming problem; it can't be done by a regular expression. One way is to use a mask: % sed -e "s/./x/g" < original.txt > mask.txt % paste mask.txt origina
