A few days ago, I wrote a server in Node.js, the purpose of which is to email me when an API found in Nuget is updated. I thought the project would take a few hours, but as it turned out, it took several days. You may ask “How is this possible for such an easy problem?” Unfortunately, I …

WebSockets is a communication protocol on TCP between a web browser (or other client) and a server. It is full-duplex, event-driven. One important advantage of the technology is the elimination of the client polling of the server. The following post lists some resources for C# WebSockets (1). C#/WebSocket Resources System.Net.WebSockets (client only) https://www.nuget.org/packages/System.Net.WebSockets/ First release Monday, June 27, 2016 …
With the release of NET Core, the acquisition of Xamarin and Mono, and the 15 or so years of development of the NET Framework, we now have three platforms to choose from for C#. Why are there three platforms? What are the differences between each? And, what is the performance of the three to each other? From the NET …

Debugging C# programs that run on a Linux server can be a challenge. On Ubuntu, a server may not have the Unity GUI installed, so you can’t use MonoDevelop. Even if the server had the GUI, MonoDevelop often does not work with a C# project because it doesn’t support many Visual Studio 2015 projects. Visual Studio supposedly can cross-debug a …

OK, really simple. I want to install Docker on an Ubuntu box. Should be easy. Right? Wrong! When I do a Google search for “install docker”, Google returns a link to the Docker installation page for Ubuntu. That’s fine, but following the 18 page/2000 word installation is insane. The first time I did that, it …
I’d like to start with a short story. I’m trying to write a simple Hello World program. I want it to run on Android, and it must use Xamarin Forms, and use XAML to describe the UI. Should be easy, 5 minutes to do, right? Not in my case. I go into Visual Studio and …
Somewhere in the many years that Microsoft has been developing Visual Studio, they’ve managed to completely mess up the Most Recently Used (MRU) list of projects in the Start Page. It used to be that if you opened a project, it would appear at the top of the list the next time you open Visual …
Mongo is a popular NoSQL database nowadays. It has several advantages compared to relational databases (schema-less, key-value store, scalable, distributed, propagated consistency) but the main advantage, IMHO, is that JSON is the lingua franca for the data structures it stores and the queries you use. JSON is a nice, simple data structure representation. It can be easily …
I’m in the process of checking out the advantages and disadvantages of GoDaddy’s new Cloud Server product, which has just been announced as generally available. It has few features, less compared to DigitalOcean, which has been available for a few years. AWS, which has been available for even longer, is generally the gold standard–if you …
Dokku is a PAAS implementation, useful for websites, servers, or development. As it notes in its website, the installation in a Debian host running Bash is just three steps: # only works on debian systems! wget https://raw.githubusercontent.com/dokku/dokku/v0.5.3/bootstrap.sh sudo DOKKU_TAG=v0.5.3 bash bootstrap.sh # go to your server’s IP and follow the web installer The last “step” …
