What is IL – practical example
I’m sure you know your C# code is not directly compiled into machine code and ran. It is first converted into IL. CIL to be precise. Its stands for Common Intermediate Language. This CIL is then assembled into bytecode and compiled by JIT (Just-in-time compiler) into executable machine code. So much for the theory, but have you ever tried to mess with IL yourself? Not? Lets try it. Run the Visual Studio Command Prompt from the start menu. Find yourself suitable directory to tinker around. Create a program, compile it and run: C:\Dev\ilmagic>copy con p.cs public class p { public static void Main() { System.Console.WriteLine("Hello console!"); } }^Z 1 file(s)…

The talk is prepared together with the C.I.C. Software GmbH and my company (CODEFUSION). The Clarion part is supervised by Andrzej Skolniak from the C.I.C. We will be giving the speech together. We will be talking about various interoperability solution between .NET and Clarion tried out in one of the projects my company I co-developing with C.I.C. Software. The interoperability solution that is based on unmanaged exports – modified .NET libraries that are accessible form Clarion. The managed…

Scaling CI–switching poll to push
Scaling CI has many flavors. For example: When: Code base / test no. increases -> build time increases, Teams grow, No. of projects grows. Then: Create targeted builds (dev build, qa build), Write fast unit tests, Smaller teams with local integration servers, Modularize the code base: Scale hardware, Add more build agents, Parallelize. and last but not least: Ease the source control system. Let me show you how to make Subversion and (TFS) Git pro actively inform Jenkins CI about changes in source control. The most straight forward way to let the CI server know that something changed in the repository is to configure polling. What it means is that…

Vanilla build server and a little NuGet gem
Vanilla build server is a concept that says that the build server should have as few dependencies as possible. It should be like vanilla ice cream without any raisins (I have raisins in ice cream). Let me cite the classic (from: Continuous Integration in .NET): “It’s strongly suggested that you dedicate a separate machine to act as the CI server. Why? Because a correctly created CI process should have as few dependencies as possible. This means your machine should be as vanilla as possible. For a .NET setup, it’s best to have only the operating system, the .NET framework, and probably the source control client. Some CI servers also need…

Software decay
At my company CODEFUSION we are working with bigger and bigger customers. We are getting hit by terms that were little known to us until now. Last time we did get a contract to sign with a term (literal translation from Polish) software “illness”. The word illness was in quotation marks. The term was new for me, so I started to dig. It turned out that what was meant here was probably “software decay” (called also software rot, code rot, bit rot, software erosion or software entropy). It was something we all software developers are fighting with. Sometimes without knowing it has a name. Software does not change, bits don’t…

WCF services behind NAT problem and solution
Problem: We have a set of WCF services working on a server. We have an ordinary ASP.NET page that calls one of the services to display its state. When we call that page we is supposed to look like this: Green page indicates everything works fine. At a customers we’ve installed the services. The message was: There was no endpoint listening at http://…/Services/BasicDataService.svc/DeliverServiceState that could accept the message. This is often caused by an incorrect address or SOAP action. See InnerException, if present, for more details. We quickly discovered that there was nothing wrong with the services. Our app worked fine and we were able to call the “.svc” endpoint…

Pictures from DWX’14 conference
This year I was once again an invited speaker at the Developer Week conference in Nuremberg, Germany. I was speaking (in German of course) about the basics of hardware programming in .NET. Developer Week is biggest developer conference in Germany: 250 session, 150 speakers. It consists of .NET Developer Conference (DDC), Web Developer Conference (WDC) and Mobile Developer Conference (MDC). Here are some pictures from the conference.
