Open-source radix/mtrie implementation in C? |
|c|algorithm|data-structures| |
I intend to use RADIX / MTRIE as my preferred data-structure for a routing implementation. I would like to know if there's a decent open source implementation available (apart from freebsd-net) which I can use for my purpose, or do I need to write one myself. |
How do you get a string from a MemoryStream? |

VSTO wraps Office's Automation interfaces. Office is doing the work under the covers, so must be installed. |
You can probably use `svn blame` to get the date each line was changed and then use `sed` to pull out only the year and month and then use `sort` and `uniq -c` to generate a useful report. |
Security in what sense? Either way it really depends on what script is running and how well it is written. Too many scripts these days are half-assed and do not properly do input validation.

In my experience, no; you just have to properly mutex yourself when you write to those values, or structure your program such that the threads will stop before they need to access data that depends on another thread's actions. My project, x264, uses this method; threads share an enormous amount of data but the vast ma... |

I'm working on a big .NET 1.1 project, and there exists a wish to upgrade this, majorily to be able to use better tools like Visual Studio 2008, but also because of the new features and smaller amount of bugs in the .NET 2.0 framework.

Help! I am using JQuery to make an AJAX call to fill in a drop-down dynamically given the user's previous input (from another drop-down, that is filled server-side).

You should use extern "C" anytime that you include a header defining functions residing in a file compiled by a C compiler, used in a C++ file. (Many standard C libraries may include this check in their headers to make it simpler for the developer)
For example, if you have a project with 3 files, util.c, util.h, and... |

I would second the Magento suggestion. It has a modern code base and is designed with extensibility in mind. It also has multi-site, multi-language capabilities engineered in from the start. It's open source _and_ seems to have a disciplined development team (with a MySQL AB -like business model) behind it . |

Do you use the Inductive User Interface pattern in Windows Forms? |

What is the difference between precedence, associativity, and order? |
|c#|arithmetic-expressions| |
This confusion arises as most people are trained to evaluate arithmetic expressions as per PEDMAS or BODMAS rule whereas arithmetic expressions in programming languages like C# do not work in the same way.
What are your takes on it? |
I would say that something that is meant to be sometimes used as a Map and sometimes as a Set should implement Map, since that can be viewed as a set of keys or values as well as a mapping between keys and values. That is what the Map.containsKey() and Map.containsValue() methods are for. |
I was thinking about this a little more and realised that while dynamic proxies will work (it's how RMI (used?) to work), if you really want this sort of functionality you would be better off looking at aspect oriented programming (AOP) using something like AspectJ (eclipse.org/aspectj).
This way you can get several... |
If I had to pick one, it would have to be AWK. It's lightweight, has a small learning curve and has many useful functions like index and substr. |
I'm a huge fan of Castle. I love the facilities it also provides beyond the IoC Container story. It really simplfies using NHibernate, logging, AOP, etc. I also use [Binsor][1] for configuration with Boo and have really fallen in love with Boo as a language because of it.

Unless you have a strong reason for refactoring (because you are going to add more classes like those in near future) the penalty of changing the design for such a small and contrived example would overcome the gain in maintenance or overhead in this scenario.

We're looking at doing the same migration right now Tobi. First, you can get a good idea of what to expect by making a copy of your project (or a portion of it) and give it a "dry run" through the .NET 2.0 compiler.

People say that the major thing TCP gives you is reliability. But that's not really true. The most important thing TCP gives you is congestion control: you can run 100 TCP connections across a DSL link all going at max speed, and all 100 connections will be productive, because they all "sense" the available bandwidth. ... |

Remote Installation Services and/or Windows Deployment Services. One or the other comes "free" with Windows Server (RIS with Windows Server 2003 SP1 or earlier; WDS with Windows Server 2003 SP2 or later), and is pretty easy to set up and use. :-) Requires your computers to support PXE booting, however. |
Oh here's a good one: since the XML serialization code is generated and placed in a separate DLL, you don't get any meaningful error when there is a mistake in your code that breaks the serializer. Just something like "unable to locate s3d3fsdf.dll". Nice. |

The only issue I've seen is with name conflicts. You'll need to dis-ambiguate any class or method names in your code that share names with ones added to the .net framework between .net 2.0 and 3.5 |
In addition to the app configuration stuff mentioned above, if you use any XSD validation you will need to replace some code around loading and validating XML. |
