Heres why you should use gRPC for everything

gRPC makes calling services on other applications or servers very easy. It is blazingly fast, and uses protocol buffers to deliver very compact messages! gRPC is a “remote procedure call” system that initially was developed by Google, counterintuitively Google claims the g in gRPC does not stand for anything Google related, but come on, we know it does 😉 gRPC is a high-performance open-source RPC framework than can be used by almost any language. Most popular languages are supported with already written libraries and new ones are created every month. What does gRPC solve? gRPC makes calling services on other applications or servers very easy, it is based on Protocol buffers so you are able to create a very clear interface and service description with .proto files, and these proto...

Git does not remember username and password on Windows

Git does not remember username and password…! I was having issues, where Git would not remember my credentials for some repositories on Windows. Usually, the repositories are stored on AzureDevops and use Windows Authentication as default, with PAT (Personal Access Token) as a fallback. In this case, since I am not an employee in the company, I was given a PAT. But git kept asking me to enter credentials for every operation against the repository origin and it was making me crazy that it was not remembering my credentials. Make sure that you are using Windows Credentials manager If you are using Git on Windows, you should store your credentials in the Windows Credentials manager, so they are properly encrypted and protected. You can check this by running the following...

10 tips for conducting code reviews

Code reviews are a common part of most development teams workflow these days and for good reason. Code reviews give us a process of keeping code quality high, sharing knowledge. catching mistakes and keeping a consistent code base. If you use git, you probably already heard about pull-requests, which basically is a merge request with a code review requirement. I help teams learn to conduct productive and positive code reviews, so the process becomes an enjoyable part of their development life-cycle. Here are my 10 tips for conducting a productive and positive code review, that gives value to both the reviewer and the author(s). 1.

You don’t need a IDesignTimeDbContextFactory

If you have ever gotten the error message, that tells you to add IDesignTimeDbContextFactory to your project, when doing EF Core migrations. This particular one: Unable to create an object of type ‘MyContext’. Add an implementation of ‘IDesignTimeDbContextFactory’ to the project, or see https://go.microsoft.com/fwlink/?linkid=851728 for additional patterns supported at design time. You will probably be scratching your head, asking some questions and maybe even swear a little. Because the console will tell you to implemnt a IDesignTimeDbContextFactory so that is But don’t fret, you don’t need one. You can avoid it by having making sure of the following: The entire solution must be buildable and be able to run! If you have a project that cannot build, you can exclude it with the build configuration manager. Default constructor For the system to...

Debugging

Hunting .NET memory leaks with Windbg

Recently a client called me about an issue where one of their production servers would run out of memory, every other week. The application in question was a .NET Framework 4.5 Windows service, that runs in an Azure VM, and ever so often it would become unstable and start causing trouble. I have previously helped this client set up an ELK stack, so it was quick for me to go into Kibana, look at metricbeat data, and see that their server indeed slowly was eating up memory over time. And every time the application was restarted, the memory would return to normal, and slowly creep upwards again. As you can clearly see, the application uses gradually more and more memory over time. Every time the line drops, was a restart...

10 tips and tricks for solving software problems

As software consultants, we are often faced with bugs or problems the client cannot fix themselves. We are expected to quickly figure out the problem, and propose or implement a solution. Through my career I have developed a sort of mindset to get to the bottom of issues without wasting time hunting deadends or non-issues, and deliver results and value more efficiently. Here is my list of 10 tips for how I go about solving software problems 1. Focus A common problem I saw in myself, and I see very often in software developers, is a lack of focus. If you are trying to solve too many issues at once, you will probably fail at all of them. The first thing you must do, is figure out what you are...
