Dr. Brian Callahan @bcallah@bsd.network

Do you have a Mac (running macOS) and an #OpenBSD machine? Would you like your OpenBSD machine to act as a secondary monitor for your Mac via AirPlay?

Test out this port and reply to the list if it works for you: https://marc.info/?l=openbsd-ports&m=174331110811177&w=2

Thanks! Let's get this in before 7.7.

Got UxPlay (https://github.com/FDH2/UxPlay) ported to #OpenBSD. Now I can use this underpowered (but free) Chromebook I got last year to some actual use as a secondary monitor for my MacBook Pro.

I built a native GCC 14.2.0 for Mac OS X 10.4 Tiger PowerPC.

I fired up the old iMac G4 and now you can build and run #oksh using the IBM xlc compiler for Mac OS X. It works on Tiger at least, 10.4.11.

Let's explore virtualizing the different BSDs on Apple Silicon.

Let's bootstrap the GNAT Ada compiler for macOS/aarch64, since I couldn't find any binary packages for it.

I decided to make one last release of the CLI version of my Free Bee game. I know #FreeBSD and #OpenBSD have packages for it, and it has been broken for the better part of a year because the server the game relied on was shut down.

If you like The New York Times game Spelling Bee, you'll like this; it's a clone of that game.

Now it's offline-only, so people can play whenever they want.

I may or may not make one last release of the web version of the game. I'd have to remake it all from scratch if I did, as the original source code has been lost.

A wild #blog post appears.

A tutorial for setting up a cross compilation environment using FreeBSD/amd64 as the host and macOS/aarch64 as the target.

I bootstrapped GDC on macOS/aarch64, since I couldn't find anyone else who had done so.

One of my cybersecurity students was selected to be on the inaugural US Women's Cyber Team and I think that's amazing!

I'll be at BSides St. Pete on September 14, presenting some of my cybersecurity research lab's work with two of my students.

Do I know anyone in that area?

Here is the spiel for my August 7 NYCBUG talk: https://www.nycbug.org/index?action=view&id=10699

As I said before, if you're in the #NYC area, come by and say hi. It's a fun talk I've been workshopping; you'll leave with some good laughs, learning some new technical knowledge, and learning how to be a better advocate for the BSDs (or whatever your open source/free software niche is).

Hey #BSD people. I'm speaking at NYC*BUG for the August meeting. If you're in or around #NYC come by say hi.

I, uh, have no idea where the venue is. I think NYU?

As for what I'm speaking about, I think I'm going to workshop a new talk. Designed to be funny and push the boundaries of what is truly useful for us to be doing in 2024.

Hello from Tuba (https://tuba.geopjr.dev/) on #OpenBSD! Relatively straightforward port. If this works and you can see this message, I'll post it to ports@.

One more release of my Repology cli program. Got a PR improving option handling and then noticed some small bugs in display output I made, so I fixed them.
