Mastodon is a free, open-source social networking service that is decentralized and distributed. It was created in 2016 as an alternative to centralized social media platforms such as Twitter and Facebook. One of the key features of Mastodon is the use of the WebFinger protocol, which allows users to discover and access information about other users on the Mastodon network. WebFinger is a simple HTTP-based protocol that enables a user to discover information about other users or resources on the internet by using their email address or other identifying information. The WebFinger protocol is ..read more

I have been blogging here for the last 20 years. Every Tuesday and Thursday, quite consistently, for two decades. But last year, without planning it, I got tired and stopped. Not sure why. It didn't correspond with any life events. Nothing interesting or notable happened. I just stopped. I did find joy on TikTok and amassed a small group of like-minded followers there. I enjoy my YouTube as well, and my weekly podcast is going strong with nearly 900 (!) episodes of interviews with cool people. I've also recently started posting on Mastodon (a fediverse (federated universe)) Twitter alternativ ..read more

I am not a Home Assistant expert, but it's clearly a massive and powerful ecosystem. I've interviewed the creator of Home Assistant on my podcast and I encourage you to check out that chat. Home Assistant can quickly become a hobby that overwhelms you. Every object (entity) in your house that is even remotely connected can become programmable. Everything. Even people! You can declare that any name:value pair that (for example) your phone can expose can be consumable by Home Assistant. Questions like "is Scott home" or "what's Scott's phone battery" can be associated with Scott the Entity in t ..read more

I was reading Gabby's blog post about the new TypeScript/JavaScript project experience in Visual Studio 2022. You should read the docs on JavaScript and TypeScript in Visual Studio 2022. If you're used to ASP.NET apps when you think about apps that are JavaScript heavy, "front end apps" or TypeScript focused, it can be confusing as to "where does .NET fit in?" You need to consider the responsibilities of your various projects or subsystems and the multiple totally valid ways you can build a web site or web app. Let's consider just a few: An ASP.NET Web app that renders HTML on the server but ..read more

I've talked about how I love a nice pretty prompt in my Windows Terminal and made videos showing in detail how to do it. I've also worked with my buddy TooTallNate to put my real-time blood sugar into a bash or PowerShell prompt, but this was back in 2017. Now that I'm "Team OhMyPosh" I have been meaning to write a Nightscout "segment" for my prompt. Nightscout is an open source self-hosted (there are commercial hosts also like T1Pal) website and API for remote display of real-time and near-real-time glucose readings for Diabetics like myself. Since my body has an active REST API where I can ..read more

I wrote a Tiny Virtual Operating System for a 300-level OS class in C# for college back in 2001 (?) and later moved it to VB.NET in 2002. This is all pre-.NET Core, and on early .NET 1.1 or 2.0 on Windows. I moved it to GitHub 5 years ago and ported it to .NET Core 2.0 at the time. At this point it was 15 years old, so it was cool to see this project running on Windows, Linux, in Docker, and on a Raspberry Pi...a machine that didn't exist when the project was originally written. NOTE: If the timeline is confusing, I had already been working in industry for years at this point but was still p ..read more

If you're excited about Hot Reload like me AND you also want an "A" grade from SecurityHeaders.com (really, go try this now) then you will learn very quickly about Content-Security-Policy headers. You need to spend some time reading and you may end up with a somewhat sophisticated list of allowed things, scripts, stylesheets, etc. In DasBlog Core (the cross platform blog engine that runs this blog) Mark Downie makes these configurable and uses the NWebSpec ASP.NET Middleware library to add the needed headers. if (SecurityStyleSources != null && SecurityScriptSources != null && ..read more

.NET 6 is released and it's a LTS release which means it'll be fully and actively supported for the next 3 years. If you've been paused waiting for the right time to upgrade to .NET 6, it's a good time to make the move! Right now, Hanselman.com and Hanselminutes.com (my podcast) are running on some version of .NET 5. You can se by visiting them and scrolling to the very bottom in the footer as I've added a git commit hash and Azure DevOps Build Number and Build ID to an ASP.NET website and I'm using RuntimeInformation.FrameworkDescription to output the plain text version of .NET I'm using.
