There are a handful of interesting USB webcams out there, which naturally work great with a computer. But what if you want to combine video from a USB webcam with your HDMI cameras in a video switcher like the ATEM Mini? ⌘ [Read more](https://aaronparecki.com/2022/01/11/8/convert-usb-webcam-to-hdmi) 2022-01-17T15:55:57Z **How to Green Screen on the YoloBox Pro**

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. ⌘ [Read more](https://aaronparecki.com/2022/01/29/12/raspi-usb-webcam-hdmi) 2022-09-16T01:04:51Z **New Draft of OAuth for Browser-Based Apps (Draft -11)**
With the help of a few kind folks, we've made some updates to the OAuth 2.0 for Browser-Based Apps draft as discussed during the last IETF meeting in Philadelphia. ⌘ [Read more](https://aaronparecki.com/2022/09/15/30/browser-oauth) 2022-11-14T16:09:21Z **How to Build a Restreaming Server with a Raspberry Pi**
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. ⌘ [Read more](https://aaronparecki.com/2022/11/14/9/raspberry-pi-restream) 2022-12-02T23:00:00Z **The Laws of OAuth**
The first law of OAuth states that the total number of authorized access tokens must remain constant in an isolated system. ⌘ [Read more](https://aaronparecki.com/2022/12/02/23/laws-of-oauth) 2022-12-22T19:59:55Z **How to create a keyboard shortcut to export the current slide in Keynote**
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. ⌘ [Read more](https://aaronparecki.com/2022/12/22/10/export-current-slide-keynote) 2022-12-22T19:59:55Z **How to create a keyboard shortcut to export the current slide in Keynote**

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 ... ⌘ [Read more](https://aaronparecki.com/2023/03/07/3/bluesky-custom-domain) 2023-03-10T01:09:09Z **OAuth Support in Bluesky and AT Protocol**
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! ⌘ [Read more](https://aaronparecki.com/2023/03/09/5/bluesky-and-oauth) 2023-10-23T16:12:55Z **OAuth for Browser-Based Apps Draft 15**

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 ... ⌘ [Read more](https://aaronparecki.com/2023/12/01/18/riding-brightline-train-miami-orlando)
