I've built several open source packages, some touching almost 500.000 downloads. But I feel that not everybody understands #OSS (open source software). We need your help in making the community better. svrooij.io/2024/09/18/o... #community

Did not expect sample code in #python at @techorama.bsky.social 💁🏼‍♂️ let's ask copilot to transpile it to #dotnet afterwards 😜 Building a production ready agentic ai app by @jeffprosise.com

Let's go @maddy.fm and @tommasostocchi.dev in Aspiriefy your app in an hour! How cool to be on a stage that fits yourself 4 times in height!! #techorama @techorama.bsky.social

Today marks the start of @techorama.bsky.social The Netherlands in Utrecht. Very curious to what I'm going to see 🤩 #techorama If you see me walking around, I won't bite, just have a coffee with me.

Hey @bsky.app, any chance we could get real multi-factor authentication set up for login and account changes? Sending two-factor codes by email is a joke. You might as well write them on postcards. No, sending by SMS is not an improvement. How did you launch without even implementing a TOTP?

🍽️ #PowerShell Conference Europe MiniCon 💬 No more, module not found 🎤 @svrooij.io ⌚ 13th October - 1pm CEST 🔗 synedgy.com/psconfeu-minicon/ #️⃣ #PSConfEU #Conference #automation #IT

Have you seen the recent version of Microsoft.Graph.Authentication #powershell? It has my contribution in it to fix the issues with dependencies. svrooij.io/2026/10/06/m...

Last session at #cybersec Netherlands the "inactive" privacy officer Pieter is explaining about the DigiD debacle.

I just programmed my Kincony KC868-M16-V2. A 16-port CT clamp measuring device. I'm hoping this will allow me to measure current on 16 individual devices. #geek #nerd

I'll be installing this Kincony M16 v2 board to measure realtime power usage of 16 different devices/rooms. And then get rid of all those power measurement devices around the house.

Smartify your not so smart doorbell with this €25 euro device and 15 minutes of your time. svrooij.io/2026/08/14/s... @home-assistant.io @zuidwijk.com Super easy to do and brings a lot of joy (for me at least) #homeautomation

Want to create your own custom integration for @home-assistant.io ? Check out my setup for easy debugging with breakpoint support svrooij.io/2026/08/11/e... #development

Over a year ago I added PKCE support in @home-assistant.io why I wanted this? Check out svrooij.io/2026/08/11/h... #security

Renewed as #Microsoft MVP ✅ svrooij.io/2026/07/16/v...

What did you get this time? Well I'm giving a talk on home automation with #dotnet, and I want to show how you can use a cheap wifi chip to mod a dump light to be wifi controllable. #esphome

What do you think is in this small box (screwdriver for reference), it is worth around €600 😯 and has to do with #security

I'm stoked to tell all off you that I joined the organizing team for @dotnetzuid.nl #community meetup #dotnet www.dotnetzuid.nl

@svrooij.io check this out github.com/TheJoeFin/tr...

I had the pleasure to speak a @dotnetzuid.nl and share my latest #security project. An introduction to IdentityProxy. Check out my key take aways svrooij.io/2026/01/23/i...

And we're off...! We're starting the evening with @svrooij.io explaining how to "Hack your protected API for integration testing". Thanks to #Promexx for hosting us.

I've been building apps and libraries to control Sonos speakers for a very long time. Sonos2mqtt has over 500.000 docker pulls. Now today I got a hold of information on how the details for third party media servers are stored. Have to get this into those libraries. More soon, please follow ☝️✅

Any Bacardi fans here? Selling my Bacardi bomber jacket, any profits go to a good cause link.marktplaats.nl/m2344271314?...

Tell me how old you are, without telling me your age? Let me start. I have this box in the attic with these things in it. (Which I bring to the @homecomputermuseum.computermuseum.social.ap.brid.gy next week)

A new way to grow as a speaker. EngageTime will soon give you clear analytics across all your sessions. See your impact, your ratings, your reactions. Understand what resonates so you can step on stage with even more confidence. engagetime.live

Want to test your api without disabling authentication? Check out Identity Proxy, which allows you to hack your api for integration testing! svrooij.io/2025/11/19/i... #security #dotnet #development

Did we need another nugget package? I sure think so! Check out this source generator that will help you automatically register your minimal endpoints. github.com/svrooij/dotn... Inspired by a YouTube video from @milanjovanovic.bsky.social some time ago. #dotnet #webapi

Want to present at our new Stockholm SQL usergroup? We're doing in-person sessions about once per month. If you can't make any of those specific dates, reach out to @transmokopter.bsky.social or me, and we'll work something out for you!

Are you still using the WithSecret or WithCertificate methods on the #microsoft identity client? Check out this post to see how that can be replaced with a managed identity. svrooij.io/2025/10/10/s... #security #development

@vandervalk.pro Is all ready for the last talk of the day at #netassemble "Dont let your access tokens be stolen" #security

#azurefest 2025 let's go

Did you know you can leverage the Azure DevOps Rest API in Power Automate to run actions that are not available in Power Automate?🚀 In the example below, I wanted to detect what is the current iteration for a project and obtain its data to send in some automated messages👇

Unlock the power of raw Kestrel! Learn when to skip WebApplicationBuilder and directly leverage Kestrel for optimized .NET apps. Ideal for low-level control and performance tuning. #DotNet #Kestrel

Anyone ever used RapiDoc? rapidocweb.com to provide developer docs about your api? Alternative to Swagger and Scalar. How not decided which one is the best. #openapi #developer

I just used the "Start from backup" flow to migrate @home-assistant.io from one machine to the next. And WOW, I never had such a smooth migration. 🥇 Other companies can learn something from this!! www.home-assistant.io/common-tasks... Migrated home assistant from arm64 to amd64 with zero issues

Building an application that used role based access control? Here is a nice trick to not have to built any user and or role management things in your app. Just off-load this to the remote security team using Microsoft Entra. svrooij.io/2025/08/27/e...

Zelf een video maken om je eigen straatje schoon te vegen in plaats van vragen van journalisten te beantwoorden: bij Follow the Money kennen we dit trucje maar al te goed. Mensen onder vuur verspreiden zo hún versie van de feiten om kritiek te ontwijken. Hoe gaat FTM hiermee om?

A rare, but highly welcome change. Microsoft changed the license requirement for Token protection from Entra ID P2 to P1. This will protect more customers in the long run and lead to a more secure ecosystem. learn.microsoft.com/en-us/entra/...

Recently, we announced the finalists for the most special of the #GoldenClippyAwards The #ChuckNorris award is for heroes in multiple areas: @nathanmcnulty.com @fabian.bader.cloud @bindertech.se @knudsenm.bsky.social@mortenknudsen.net Congratulate them/reshare for these rockstars! #MVPBuzz #WPNinjas

Have a Volvo and using @home-assistant.io ? The Volvo On Call integration is broken. It has been replaced by a new integration that connects to the new api. I'm now creating the depreciation message.

Did you know you can "pre-provision" application access to your sharepoint group site using the `resourceBehaviorOptions` array when you create a group? add `appRoleForSite:{appId}:fullcontrol` Ow, wait this is NOT documented 😂 learn.microsoft.com/en-us/graph/... #graph #microsoft

Did you know #winget has almost 10.000 apps? Details on which packages got updated, and when? github.com/svrooij/wing...

Do not ask #github #copilot to do the migration, ask it to write a migration plan 🥇 svrooij.io/2025/08/19/v... #development #dotnet #devproxy
