Antti K. Koskela is a Finnish Software Developer / Generally Geeky Person working as a Cloud Solutions Architect for Etteplan, living as a hermit in the beautiful Finnish countryside. Koskila.net is his personal professional (i.e. professional, but definitely personal) website.
Okay, let’s drop the third person speech. You can read more about me and stuff I do from here: https://www.koskila.net/antti-koskela/
In addition to this being my personal home page (nowadays, I guess that means a catalogue and links to my other stuff online in different channels, right?), I’m blogging about all kinds of exciting and/or tricky topics.
See a few of my latest blog articles below:
- HttpContext.WebSockets.IsWebSocketRequest always null in .NET Core?This article explains another simple fix to an annoying issue. I guess that’s how I start like every other one of my little tutorials, but hey, it’s true! I suppose I just have a knack for running into issues that come with poorly documented fixes or workarounds that are obvious, but only in hindsight… Right? Anyway, this time my websocket requests were not being handled as such by my ASP.NET Controllers. “IsWebSocketRequest” was suggested by IntelliSense, but it would always be null in the code.…Continue reading HttpContext.WebSockets.IsWebSocketRequest always null in .NET Core?
- Docker-compose fails on Windows with “Error while fetching server API version: (2, ‘CreateFile’, ‘The system cannot find the file specified.’)”Once again, I come to you with a surprisingly opaque problem, and offer to share my bemusingly simple solution. That should be a dedicated series on my blog – although on second thought, perhaps lobbing 90% of my articles under one tag wouldn’t be helpful… 😁 Problem When running docker-compose up the command would fail, and instead output a disgustingly long set of what looks like a whole pile of pythons engaging in quantum entanglement would angrily hiss at you, if bothered. It’s not pretty.…Continue reading Docker-compose fails on Windows with “Error while fetching server API version: (2, ‘CreateFile’, ‘The system cannot find the file specified.’)”
- Azure DevOps suddenly 404s for your project? Easy fix!This article explains a quick solution to a pretty common problem with Azure DevOps. Namely – random and annoying 404 (or sometimes 401) errors when trying to access your dear team projects. I forgot to take screenshots of the errors and couldn’t figure out how to reproduce it, but hey, the fix is the main point, right? 😀 If you’ve ended up on this page, you’ve probably encountered the issue already, so why would you care about the screenshots anyway. Solution Ok, so this is…Continue reading Azure DevOps suddenly 404s for your project? Easy fix!
What’s koskila.net about?
The tagline for my blogging efforts has been Solutions are worthless unless shared for quite a while already. That’s to say, since I’ve gotten a lot of help from the community whenever I’ve had issues getting something to work, I like to give something back. This blog is my way of doing that.
Blogging has been a great, lightweight way to sort my thoughts and document weird fixes and findings along the way. And boy, has there been a lot of them! Microsoft’s stack always keeps surprising me – mostly in a positive way, but there’s an occasional bump along the way too.
A lot of people seem to struggle with the same issues, as the blog nowadays has some 70 000 visitors monthly. May you find my thoughtful workarounds as useful as I have!
In addition to more technical posts, sometimes I might post about my sessions at different community events, or experiences as an expat living in a foreign country (in 2017, that country was the USA, in 2018 & 2019 Canada). Right before the pandemic, I moved back to Finland to live in the middle of a forest.
Back in the olden days, when the world was not on fire, I used to travel to different events. Now it’s all digital, which is… Not quite the same.
You can also see a list of all my sessions and session materials.
No upcoming engagements. Would love to meet y’all again, after we’ve got a vaccine or something.
