Don't be nice
Sometimes, it's more important to be good than it is to be nice.

Ok, not using the new #CSharp unions just yet, but already made a couple of abstract classes closed, to get the exhaustiveness benefit and get rid of the fugly default switch branch throwing an exception.

I've gone back and forth with the result pattern, and where I landed on eventually is that I like it, but not to spread it everywhere. (yet another case of me going all in, eventually feeling the pain of my stupid decisions, then scaling back 😅)

Gotta love the obsession with removing all code from #AspNetCore controllers/minimal apis, moving it to some mediator type handler thingy, to "avoid coupling with HTTP details", then proceed to create a bunch of abstractions to map stuff like HTTP status codes 🤷‍♂️

Three cards titled "The Industry", "The Diagnosis" and "The Treatment". The industry creates devices that need constant attention, designs services that never finish, and builds products that generate obligations. The diagnosis: you're addicted, you lack self-control, you need to unplug. The treatment: focus modes, wellness apps, digital detoxes, screen time limits — all of which are more products that need you.

Some math ain't mathing for me right now 😅 In the MS MVP website, it says this is my 9th year in the program. However, my first award was in 2019, we're in 2026, so it seems the count is incorrect?! There's an off by one error somewhere, either in my head, or on the MVP website 😂

It continues to baffle me that the default messaging app used around these parts (PT/EU) is WhatsApp, when Signal, which, as far as I'm aware, has (relevant) feature parity and is just as easy to use, is right there...

So now there are two main European atproto providers (PDS and client), one is open source and one is closed source. Very concerned that the EU talks about how important OSS is, and then they pick the closed source one :/

If a service crashes while writing to S3, the incomplete multipart upload will sit there. Without cleanup policies in place, it will sit there forever, taking up space and costing money. Today's lesson: enough crashes with large enough payloads, quickly racks up terabytes of "invisible" trash 😅💸

Trying out filen.io, to move my things off of Google Drive, and it's looking pretty interesting. It includes some features that I've been looking for, but hadn't found generally available, like sync specific directories, file versions, an event log and a .gitignore like file to define exclusions.

There are two ways to resolve the cognitive dissonance of being on Twitter while also caring about all the awful shit happening because of Twitter 1. Leave Twitter 2. Stop caring Profoundly disappointing how many people I like seem to have chosen the latter

If I did depend on that income though, this story wouldn’t be funny, it would be terrifying, because my livelihood could be in question, just because someone, or something, thought IPTV = illegal pirates 🏴‍☠️.

All of this to say (besides being a bit sad that for all the hundreds of thousands of views of my content, plus usage of my open source code and samples, only one person thought it was a worth contributing, but I digress), I don’t depend on the income from Buy Me a Coffee.

I’ve had the blog since 2016, started creating open source code samples by the same time, created the YouTube channel in 2017, and created my Buy Me a Coffee account in 2022. During all this time, I got a total of… 1 person "buying me a coffee".

Maybe with the football world cup imminent (or some other sports event) they are more sensitive to these kinds of things, though that doesn’t justify this sort of mistake.

João Antunes @joao.antunes.dev · 04/06/2026
Now, was this an automated process looking blindly for keywords, or some eager moderation team member that has no idea that IPTV isn’t synonymous with pirating? No clue, but in either case, doesn’t make any sense.

I built IPTV applications a long time ago, when my job was building them for a legitimate TV provider, one of the biggest in Portugal (MEO) 🤷‍♂️.

João Antunes @joao.antunes.dev · 04/06/2026
I assume they think I’ve built some sort of application that pirates IPTV streams or something like that, but that’s shortsighted to say the least, given I’m pretty sure there is much more people building legitimate IPTV and related applications, than illegal ones.
