I would not have guessed this was possible!

Vladan Majerech has found a one-dimensional spaceship in the Game of Life: a pattern just one cell high and 3,707,300,605 cells wide that, after 133,076,755,768 generations (during which it is not confined to the one-dimensional line, of course) recreates the starting pattern but translated two cells to the right.

Trying out a whole-class collaborative project to wrap up a grad seminar (formal math) for the first time this semester, and it's actually really fun so far and seems to be working out.

The students all contributed ideas, then we voted and went with one idea, which is nicely scoped. Today in our planning class, I used my experience as a software engineer to help the class (25 people) form teams, define an MVP, pick leaders & TPMs, and agree on initial interfaces.

Now we have four teams with dedicated purposes, each with one leader and one TPM. And we have an initial intermediate data format to help with the modularity, and plans for how to iterate.

There are two days left of class to actually hack on the project, and I am cautiously optimistic, and confident in my management abilities to help teams adapt to the unexpected, too.

Anyways, we'll see how it goes. But it's energizing.

After 14 years away from coding, I finally rebuilt my old Python + GTK text editor.

From Python2 + GTK2 → Python 3, GTK4 — and now preparing a talk for GNOME Asia Summit 2025.

Feels good to build again.

Prezident Petr Pavel: Dostal jsem žádost od Petra Macinky, abych vyslechl Filipa Turka a považuju za fér, abych si ho vyslechl. Já si na rozdíl od Filipa Turka nemyslím, že by to byly pouze mediální výplody, protože to, co se kolem něho objevuje, je dlouhodobé.

Not joking: has one reporter responded to his preposterous Sgt Schultz “I know nothing” schtick by immediately asking: * Doesn’t this level of ignorance disqualify you as speaker? * Do you really think we are so dumb to believe you? * Do you think it is appropriate to insult the voters like this?

🚀 Ready to join mission control?

We're recruiting Admins to help guide our program for socials, fundraising, outreach, and program development. Enthusiastic folks with initiative read on! No Djangonaut experienced required.

Apply by Dec 12th! forms.gle/UD3gN3ngrEtAFien6

Djangonaut Space Admin Application

When we started Djangonaut Space we had 5 active and enthusiastic co-founders, but life happens and, exactly as we encourage folks to do, some stepped back for other priorities. Tim and Rachell have decided to expand the team and open the application for the admin team. What: The work required is likely 5 hours a month, depending on the role, with 1-2 synchronous meetings and other asynchronous chats. Though this is not an exhaustive list some things we are looking for help with are: Social Media (blog, brand, socials) Fundraising and Financial (grant process management, fundraising) Program Development (for sessions but also to keep past participants engaged) Outreach and Recruitment (for Djangonauts, Captain, and Navigators) Who: We prefer people who know we are and are in align with our vision and goals of the organization. Experience with or in Djangonaut Space is preferred but not required. We are hoping to find enthusiastic and empathetic people who take initiative to implement their grand ideas. The admin role is valid for one term. It comes with voting power after 3 months of experience within the community. Please read more about our admin role and what that looks like in the governance doc. The admin role is not necessarily involved in every session but does help make sure they go smoothly. When: Applications close: December 12th Followup Response: December 17th How: We will get in touch with you by December 17th. We might want to schedule a followup call with you to get to you know more. So now about you! Please fill out the form so we get to know about you a bit better and what you'd like to bring to Djangonaut Space.

Attached: 1 video I am losing my fucking mind I have a Taylor Swift playlist. It worked fine until JK updated my phone today. Now it cannot seem to finish one song without starting the next song 30 seconds in I know this sounds batshit, and I couldn't think of another way to capture it than using video mode on my iPad to record the phone Hey @SwiftOnSecurity@infosec.exchange is this how Albatross ends and The Prophecy begins? [No TS jokes, please. I've replicated this 5x and genuinely feel like I'm going insane]
