I ran across another post of someone looking to get rid of WCF on StackOverflow today. The post titled “WCF replacement for cross process/machine communication” goes into the typical complaints about configuration of WCF. I actually think this is the least of the issues I’ve had with WCF. Whatever your reason for looking to abandon [...]
Recently I ran across an article on the subject of Content Management Systems and their inability to separate content editing from content publishing. The article titled “EditingPublishingSeparation” by Martin Fowler is worth a read. I completely agree with his assertion that, from an architecture point of view, the editing and publishing of content should be [...]
Continued from: Part 2 – Enumerate Ranges and First/Last This is really the major piece of work in this release. There are a number of factors as to why these methods were added, but the foremost among them is performance when merging two sets of data. Before we go further let’s look at a typical [...]
Continued from: Part 1 – Interface Changes Enumerating Ranges I’ve been contacted several times about adding the ability to enumerate ranges from the b+tree. It’s actually a very trivial thing to implement and I’ve handed out the code several times. With this release the following range enumeration methods will be available: EnumerateFrom(TKey start) – Enumerate [...]
After much deliberation on the subject, I decided to introduce breaking changes interface. I know, I know, I don’t do this lightly, in fact I think it’s the third worse thing I could possible do (sorry it does follow adding bugs and semantic changes). So here are my reasons why I thought this was necessary: [...]
I’ve recently seen some comments about various aspects of btree/b+tree structures that are troublesome. They are, IMHO, just plain wrong. Let’s look at a few of these and see if we can shed some light on b+trees and their implementations. 1. Items in a tree node must be presorted. FALSE This is simply not true, [...]
In this post we are going to explore some great new features introduced in the latest release of the protobuf-csharp-port project. We are going to build both an IIS service to handle requests as well as a sample client. Let’s get started. Prerequisites Let’s start by fetching a copy of the protobuf-csharp-port binaries. We can [...]
Keeping in line with our previous post “How to prevent users from killing your service or process” and continuing down the road of securing our service this post looks at the prevention of debugging. There are a lot of anti-debugging posts out there, most of them written in C++ and assembly and are therefor of [...]
Before I say another word, I have read “The arms race between programs and users” and wholeheartedly agree. You can not, and should not, attempt to stop an Administrator from killing your process or stopping your service. That is not what we are trying to do here, we are trying to prevent Joe User from [...]
Continued from “Building a Windows Service – Part 6: Adding resources and event logging” So let’s recap our goals for this project: Building a service that can also be used from the console Proper event logging of service startup/shutdown and other activities Allowing multiple instances by using command-line arguments Self installation of service and event [...]
