You mention the wiki page is badly written, and I have the same feeling whenever I read about anything mathematics related on it. But... it's written by volunteers, so I'll take what I can get. Since you obviously have the talent

wow, just wow unsubscriber: a system of telephone bills and their fees which can be charged only to subscribers "every item is charged with the unsubscriber"

There is a difference between preventing a program crash and handling errors. Please don't use catch-all-exceptions clause for either, especially not in hospital machines. The difference between writing if (status != SUCCESS) and catch

I disagree with both points, in fact with every statement you made. Correctness can be achieved without use of exceptions (whether this is easier or harder to do is up for debate). Next, in some cases correctness may be sacrificed for perfo

If this is one of his worst, I must read the rest. You are unsatisfied with an essay that is merely of correct reasoning, can you recommend some even better reading material than this?

Does nobody on Hacker News watch Silicon Valley? Or are references in comments frowned upon?

I only see an O(n) algorithm there, there is no O(k). Am I missing something?

Yea, I guess that also explains why gradients don't look that smooth.

Can anyone explain the gradient merging example? If we sum an image in which luminosity is linearly rising from left to right with the image in which the luminosity is linearly rising from top to bottom, then the result should have constant

Of course you need to log some data in textual format for emergencies, but if you had a tool that indexes events on timestamps, servers, monitorees, severity and event type, while severely reducing the storage required, you would be able to

Nevermind, I managed to squint enough to get the letters to combine into a perfect image. It should not be possible to get more than 1 correct 3D image, the period of the background should be increased.

Wait, did it get your name right? It's kinda buggy for me, it draws every letter twice for me (twice in 3D, of course it has to draw it twice in 2D).

Yea, change a certain .h file and you can go get a cup of coffee while waiting for the build to end. This can't ever happen with Java/C#.

No. For radix sort this constant factor is quite low, so it outperforms std::sort in most cases. Try sorting a million integers, my results are: std::sort: 60 ms; radix-sort (LSB, hand coded, less than 20 lines): 11 ms. It gets even better

Please note that radix sort is easy to implement to work correctly with doubles, Table 1 is misleading.
