Aerial gravity surveys are not particularly new. I've done a ground-based survey, but we were looking for a weak anomaly and the region had strong topography so the results were dubious (the inverse problem is very ill-posed to begin with

Terrible example, but the point that cost-benefit analysis is nonlinear is indeed valid. Suppose that instead of being offered money, you were threatened with losing it. This change is immaterial for small amounts, but highly relevant for

Also note that libc string functions generally seg-fault when passed invalid addresses (including NULL). Implicitly expecting more sophisticated error handling in this scenario is silly.

Just like the oft-quoted two-line Haskell definition is not really quicksort, this isn't either. It has to be in-place to avoid worst-case O(n^2) space .

PageRank already has some regularization (essentially epsilon of outgoing links to everything). Also, papers don't form a DAG because people frequently forward-cite or cross-cite (because authors and their friends often have relevant work

I've heard of this scenario before, but don't understand this situation. What possible technical reason would justify a billion lines of code needing to be in one repository? If it's a matter of history, perhaps we just need a better impo

Hmm, I would have said that short-term branches with `rebase -i` are MQ on steroids. I always found MQ to be an odd beast, introducing a new set of commands that are far from orthogonal. Now that bookmarks are reasonably well-supported, a

Busybox is a binary that inspects argv[0] to determine how to behave. This is very different from shell builtins that do not launch a new executable, and will thus function correctly after the executable is remove from the file system. As

My use of "concrete types" was merely a proxy for any code upon which client code should not have an explicit dependency. I don't see interfaces and plugins as being orthogonal at all, you can't very well have plugins without interfaces (it

While that's a classic and amusing essay, having client code depend on concrete types instead if interfaces is lame unless you can be confident that they won't change their mind about which one they want to work with. I write mostly C, don

Compile-time choices are a terrible code smell. If object creation is sorted out (through dependency injection/service locator/etc), the compile-time choice can usually map to exactly one runtime option and exactly one conditional.
