You know the functionality in Excel when you type 3 rows with a certain pattern and drag the column all the way down Excel tries to continue the pattern for you. For example Type... test-1 test-2 test-3 Excel will continue it with: test-4 test-5 test-n... Same works for some other patterns such as dates and so on. I'm trying...

Hi, I once saw a programming pattern (not design), how to implement a fast copy of buffers. It included an interleaved loop and switch. The thing was, it copied 4 bytes most of the time, only the last few bytes of the buffer were copied using smaller datatypes. Can someone tell me the name of it? It's named after a person. It's done in...
I am reading a Stream, which provides an identifier (a simple int). Depending on the int different data follows, which i need to turn into objects. So far i created classes for each object type, and each class provides a read(InputStream input)-method which reads whatever data there is to be read for that kind of object (all object class...
My current project is leveraging Spring, and our architect has decided to let Spring manage Services, Repositories and Factory objects, but NOT domain objects. We are closely following domain driven design. The reasoning behind not using spring for domain objects is primarily that spring only allows static dependency injection. What i me...

I have a list of numbers like 1,2,3 and I want to find all the combination patterns that sum up to a particular number like 5. For example: Sum=5 Numbers:1,2,3 Patterns: 1 1 1 1 1 1 1 1 2 1 1 3 1 2 2 2 3 You're allowed to repeat numbers as far as they don't go over your sum. Which way would be best to program this? ...

Hi what's the recoomended approach in C# when one wants to implement a simple plugin approach? So basically I have a processing loop that I want different behavior to occrur depending on what the user selected.

Hey there, I have read the few posts here on when/how to use the visitor pattern, and some articles/chapters on it, and it makes sense if you are traversing an AST and it is highly structured, and you want to encapsulate the logic into a separate "visitor" object, etc. But with Ruby, it seems like overkill because you could just use blo...
In django admin I wanted to set up a custom filter by tags (tags are introduced with django-tagging) I've made the ModelAdmin for this and it used to work fine, by appending custom urlconf and modifying the changelist view. It should work with URLs like: http://127.0.0.1:8000/admin/reviews/review/only-tagged-vista/ But now I get 'inval...
Hey there. I'm trying to write a small program that will read the four following bytes after the last occurrence of "0xFF 0xC0 0x00 0x11" which can be converted easily to binary or decimal. The purpose is that the 2-5 bytes following the last occurrence of that hex pattern represent the width and height of a JPEG file. #include <stdio.h...

Heyho, I've got a big bunch of loglines (more or less without documentation) and need to parse the lines. The parsing itself won't be a big problem, but first I need to know how many different kinds of lines are inside the files. Besides the fact that I've got really different lines like short errors, up to bigger lines which are only di...
I'm using this pattern for singletons, in the example the singleton is PlanetEarth: var NAMESPACE = function () { var privateFunction1 = function () { privateFunction2(); }; var privateFunction2 = function () { alert('I\'m private!'); }; var Constructors = {}; Constructors.PlanetEarth = function () { privateFunction1(); ...
