... very rare cases*). This is like memoization but more active, and involves one additional step: You must pick, ahead of time, the exact order in which you will do your computations. This should not imply that the order must be static, but that you have much more flexibility than memoization. examp...

...er named HipHop that transforms PHP source into C++ code. Rasmus Lerdorf, one of the big PHP guys did a presentation for Digg earlier this year that covers the performance improvements given by HipHop. In short, it's not too much faster than optimizing code and using a bytecode cache. HipHop is o...

... fall into roughly three categories: You have a small number of points, none which are terribly close together. In this case, one of the solutions you listed in the question is likely to work with fairly minimal tweaking. You have a small number of points, some of which are too closely packed for ...

...aly do 2 different test sessions when working with celery tasks. The first one (as I'm suggesting bellow) is completely synchronous and should be the one that makes sure the algorithm does what it should do. The second session uses the whole system (including the broker) and makes sure I'm not havin...

.... In general, pandas tries to do as much alignment of indices as possible. One downside is that when indices are not aligned you get NaN wherever they aren't aligned. Play around with the reindex and align methods to gain some intuition for alignment works with objects that have partially, totally, ...

...\assembly\ is the new GAC . Does it mean now we have to manage two GACs, one for .NET 2.0-3.5 applications and the other for .NET 4.0 applications? ...

...ndamental operations. When creating an object which inherits from another one, we use Object.create(obj). But in this case we want multiple inheritance, so instead of obj I use a proxy that will redirect fundamental operations to the appropriate object. I use these traps: The has trap is a trap ...

...tempt to implement it. I’ve found two ways of detecting the zoom level. One way to detect zoom level changes relies on the fact that percentage values are not zoomed. A percentage value is relative to the viewport width, and thus unaffected by page zoom. If you insert two elements, one with a pos...

...tly what it says it is, an object, i.e. a declaration and instantiation in one. This limits object to a single instance if defined in package scope, which effectively makes it a singleton, but only if defined IN THAT SCOPE. If defined inside a class, you can have as many instances as the class itsel...
