I agree. It's definitely possible. It's just that the actual benefit is far from reducing link time to "O(changes in the input)" and it would introduce significant complexity into …

Every incremental linking technique I'm aware of involves overwriting the output file and does not guarantee that identical input files and command line lead to identical (bit-exac…

No, it is just that nobody is currently working on it. Last I talked with the Apple folks they are just busy with other stuff. Patches are definitely welcome for MachO improvements…

What Bjarne doesn't mention is the enormous difference in code size between qsort and std::sort. The flexibility of having the compiler generate a sorting routine from std::sort is…

I spent about a week going through Mahajan's OCW course "the art of approximation" (it's quite short and reads quite quickly). It changed how I view problem solving and engineering…

FWIW, a single Boeing 747 engine does about 100MW. Such an engine can be considered to "fit on a truck" for some definition of truck. Also consider that much of the size is due to …

Ballpark calculation: 400km/h ~ 100m/s air intake cross section ~ 1m^2 ==> ~ 100m^3/s of air going through radiator density of air ~ 1kg/m^3 ==> ~ 100kg/s of air going through radi…

Curiously, pNaCl also takes that same route.

It's about more than just shutting down though. Biological complexity makes it infeasible to significantly engineer our biological bodies to e.g. make them smaller to reduce fuel c…

The biggest barrier to space travel is our biology. We must create non-biological humans that can shut off and wait for the entire trip.

Here's a couple elementary examples that are useful: f[x_Integer]:=x^2 Basically the pattern for the argument of f must match the pattern _Integer, which means that the argument is…

reCAPTCHA is bar none the way to go. Not only is is robust, but it also serves a useful purpose---it uses user answers to the reCAPTCHA to digitize books by having users recognize …

FWIW, where it says "Already featuring _several hundred_ items, new content will be added regularly.", the underlining gave me an instinctive urge to click on it, expecting some so…

It ignores it only as much as the average person does.
