Should I use jQuery.inArray()?
I'm doing very frequent searches in arrays of objects and have been using jQuery.inArray(). However, I'm having speed and memory issues and one of the most called methods according to my profiler is jQuery.inArray(). What's the word on the street about its performance? Should I switch to a simple for loop? My specific function is: func...
An Exercise: map or reduce a map in Python without list comprehensions?
When I started writing this question, I didn't think of the easy solution with nested lists, but now anyway want to find one. Here's an ugly code: fun0( fun1(fun2(fun3(arg1))), fun1(fun2(fun3(arg4))), fun1(fun2(fun3(arg4))), fun1(fun2(fun3(arg4)))) Ouch! Names are given for examples. In the real application, their nam...

remap keyboard key in wpf
I have a wpf application that uses several Telerik RadNumericUpDown controls to enter measurements. Turns out that the Telerik control only accepts "." from the numeric keypad (next to the 0 on the right side of the keyboard). Most of my clients have laptops, and so they don't have this button, but they have the "." next to the "," and...

Must be : high-speed (SQL-based methods too slow due to parsing) able to get,set,update,delete both fixed and variable data types (e.g. int and string) ACID (atomic,consistent,isolated,durable) us...
Openlayers vector layer
I want to have a vector layer of the world, which shows the country borders, states and their names in English. Is there a layer that exists that I can control the colours? Cloudmade doesn't let me quite do this, nor does openstreetmap and a bunch of others. I'm thinking I might need to create a raster image and overlay that except I do...

I have found the shape data for the borders of all the countries and a class to process it and I have written a script to convert the longitude and latitude to a pixel location on an image and to draw the countries using imagefilledpolygon and imageline. Everything is working great except: 1) I have a $scale variable that I can change. ...

Common algorithm for std::list and std::map?
I have a class of interest (call it X). I have a std::list<X*> (call it L). I have a function (call it F). F(L) returns a subset of L (a std::list<X*>) according to an algorithm that examines the internal state of each X in the list. I'm adding to my application a std::map<int,X*> (call it M), and I need to define F(M) to operate in ...

What is a hashtable/dictionary implementation for Python that doesn't store the keys?
I'm storing millions, possibly billions of 4 byte values in a hashtable and I don't want to store any of the keys. I expect that only the hashes of the keys and the values will have to be stored. This has to be fast and all kept in RAM. The entries would still be looked up with the key, unlike set()'s. What is an implementation of this ...

Using std::map<K,V> where V has no usable default constructor
I have a symbol table implemented as a std::map. For the value, there is no way to legitimately construct an instance of the value type via a default constructor. However if I don't provide a default constructor, I get a compiler error and if I make the constructor assert, my program compile just fine but crashes inside of map<K,V>::oper...
