At the Wehkamp Tech Hub we support Wehkamp with technology in the broadest sense of the word: almost everything is technology. Bigger topics, like the replacement of our order management system, require careful planning over teams; we have many of those topics.
Our Head of Product also had the need to share more of the roadmap, so he asked me if I could look into the problem of generating a roadmap report we could share.
At Wehkamp we use Redis a lot. It is fast, available and implemented as a managed AWS service called ElastiCache. Sometimes we need to extract data from Redis, and usually I use the redis-cli to interact from the command-line. But what if you need to get the values of 400k+ keys? What would you do? Is there an effective way to query multiple key/values from Redis?
Turns out that I needed an even smaller type of event: the signal. It is an event that has no data; it just fires. The Strongly Typed Events project started with the IEvent event that was styled after .Net. Then the ISimpleEvent was added in 0.2.0, for scenarios when no sender is necessary. Now I’ve added the ISignal to version 0.3.0.
There are many projects that are way too small to setup an ASP.Net membership configuration or OWIN authentication. But you still want to protect your applications by one or more accounts. What to do?
Well… there is a small – but obsolete (!!) – thing that you can try: ASP.Net Forms Authentication. While it is obsolete, it is still usable. In this article I’ll show how to implement it for MVC.Net.
I can almost hear you think: “Why on earth would anyone use EMF?” Well… I don’t… but MS Office does! Thumbnails that are saved in MS Word documents are in the EMF format. As I struggled to do something with one, I realized that I had to convert it first to a more “easy to handle” format: PNG. Easier said than done.
A while ago I started a GitHub project for Strongly Typed Events in TypeScript. I’ve uploaded the second version (0.2) with support for ISimpleEvent and I changed the way you can expose the dispatcher as an event. The code is 100% backwards compatible with version 0.1 – you might need to update some references.
There are a few instances in which you’ll need to hash a combination of data. You might resort to creating one big string and hashing that. It has a clear disadvantage from a memory and processing point of few. It might even be impractical when files or streams are involved. That’s why I created a BlockHasher utility class that helps to generate these types of hashes.
In a previous blog I explored how to create a dynamic compiler. In this blog I’ll explore how to create an evaluator that aids in the compilation of classes. It will take care of the ceremony needed to wrap the code into a class, compile it and retrieve the result.
Dynamic compilation is an awesome feature to add to your projects. Especially frameworks will benefit from the compilation of dynamic expressions and scripts. There are two main ways of doing it: the Code DOM Compiler or the Roslyn project. In this blog I will show how to implement them both.
Need to add named event support to your class? Implement the IEventHandling interface or extend from the abstract EventHandlingBase class. In this tutorial I explore how you can give your class named events.
