I've seen a lot of complaints about how MCP isn't ready for the enterprise.

Update: The changes described in this blog post have been incorporated into the 2025-06-18 version of the MCP spec!

Here's where you can find me at IETF 121 in Dublin!

I just did a massive spring cleaning of one of my servers, trying to clean up what has become quite the mess of clutter. For every website on the server, I either:

The first law of OAuth states that

The sessions I will be attending and presenting at during IETF 120 in Vancouver

IndieWebCamp Düsseldorf took place this weekend, and I was inspired to work on a quick hack for demo day to show off a new feature I've been working on for IndieAuth.

The draft specification OAuth for Browser-Based Applications has just entered Working Group Last Call!

Is it called an OAuth "grant" or a "flow"? What about "grant type"?

It was 11am at the Fort Lauderdale airport, an hour after my non-stop flight to Portland was supposed to have boarded. As I had been watching our estimated departure get pushed back in 15 minute increments, I finally received the dreaded news over the loudspeaker - the flight was cancelled entirely. As hordes of people started lining up to rebook their flights with the gate agent, I found a quiet spot in the corner and opened up my laptop to look at my options.

Bluesky, a new social media platform and AT Protocol, is unsurprisingly running up against the same challenges and limitations that Flickr, Twitter and many other social media platforms faced in the 2000s: passwords!

I recently got access to the BlueSky beta, and decided to poke around to see what it's all about. I will save the details of what it is and how I feel about it for a different post. However, one of the first things you do when you sign up is choose a username that exists under the bsky.app domain. I have zero interest in another name rush where everyone tries to claim the shortest username possible, so I went with aaronpk.bsky.app rather than trying to get a or apk.

Lately I've been using Apple Keynote to create graphics for using in videos and blog posts. It's a quick way to arrange things on a page, copying and pasting most things just works, and there are enough built in shapes and tools to get the point across. However, after spending a full day creating graphics for a video, I found myself frustrated by the number of clicks required to export a single slide at a time.

The first law of OAuth states that the total number of authorized access tokens must remain constant in an isolated system.

First of all, what is a restreaming server? Sometimes you want to livestream video from a device like an ATEM Mini or OBS to multiple destinations. Many devices and software like this will let you push video to just one RTMP destination at a time.

This post exists to collect my notes on displaying a USB webcam on the Raspberry Pi HDMI outputs. This is not the same as streaming the webcam (easy), and this is not for use with the Raspberry Pi camera module. This is specifically for USB UVC webcams.

This step-by-step guide will show you how to use the chroma key feature on the YoloBox Pro to green screen yourself onto picture backgrounds and videos, or even add external graphics from a computer.
