TypeScript replaces AtScript as the preferred language for Angular 2

October last year, I wrote the following:

I heard some colleagues discuss if Angular.js will ever be written using TypeScript. The answer is no. In fact, the Angular.js team is using their own language AtScript to build Angular 2.0.

Man, could I have been more wrong! Last week S. Somasegar shared the following news:

For the last several months, the Microsoft TypeScript and Google Angular teams have been working closely together. Today at ng-conf in Salt Lake City, the Angular and the TypeScript teams are unveiling the first fruits of that collaboration.  We’re excited to announce that we have converged the TypeScript and AtScript languages, and that Angular 2, the next version of the popular JavaScript library for building web sites and web apps, will be developed with TypeScript.

Working closely with a rich library like Angular has helped TypeScript to evolve additional language features that simplify end-to-end application development, including annotations, a way to add metadata to class declarations for use by dependency injection or compilation directives.

That’s really great news and gives me hope for the future of both TypeScript and Angular.

Podman– Command execution failed with exit code 125

After updating WSL on one of the developer machines, Podman failed to work. When we took a look through Podman Desktop, we noticed that Podman had stopped running and returned the following error message: Error: Command execution failed with exit code 125 Here are the steps we tried to fix the issue: We started by running podman info to get some extra details on what could be wrong: >podman info OS: windows/amd64 provider: wsl version: 5.3.1 Cannot connect to Podman. Please verify your connection to the Linux system using `podman system connection list`, or try `podman machine init` and `podman machine start` to manage a new Linux VM Error: unable to connect to Podman socket: failed to connect: dial tcp 127.0.0.1:2655: connectex: No connection could be made because the target machine actively refused it. That makes sense as the podman VM was not running. Let’s check the VM: >podman machine list NAME         ...

Cleaner switch expressions with pattern matching in C#

Ever find yourself mapping multiple string values to the same result? Being a C# developer for a long time, I sometimes forget that the C# has evolved so I still dare to chain case labels or reach for a dictionary. Of course with pattern matching this is no longer necessary. With pattern matching, you can express things inline, declaratively, and with zero repetition. A small example I was working on a small script that should invoke different actions depending on the environment. As our developers were using different variations for the same environment e.g.  "tst" alongside "test" , "prd" alongside "prod" .  We asked to streamline this a long time ago, but as these things happen, we still see variations in the wild. This brought me to the following code that is a perfect example for pattern matching: The or keyword here is a logical pattern combinator , not a boolean operator. It matches if either of the specified pattern...
