Ordered business cards from @jukeboxprint.bsky.social and they turned out SO WELL. Plus their support has been above-and-beyond helpful. Real people actually reading my email and solving my problem. Unreal awesome.

Unfortunately I'm seeing a 404?

Oh nice! Wasn't seeing it linked from the site, but I might have just missed it. I'll have to check it out!

The dream of this sort of site is that I can keep all my own records, and syndicate them out to Hardcover for wider reach. As you pointed out, can't do it with Goodreads.

wow, that's awesome! and TIL about hardcover, that's a great looking site.

Any plans for an API?

It's wild that they're still putting cameras on the back of iPads. People use them enough to justify the weight, cost, and inability to lie flat??

Gonna leave this open for another couple of weeks. Get in while you can!

Advent of Code 2025 Day 3: Lobby A step-by-step Python walkthrough for solving Advent of Code 2025 Day 3.

Here's my 2025 day 3 #AdventOfCode solution (in #Python, per usual)! An extra clean little dynamic programming problem.

PSA: if you use @mullvad.bsky.social with any openvpn-specific docker images, you should know that they recently sunset those servers and your stuff is broken.

Luckily, there's a similar, wireguard-specific docker imager that takes just a little fiddling to get working.

Predicting the Future Take my fun little survey about the state of the world in 2041.

I also blogged briefly about it, giving a little more context about the project. There's not a lot more, it's really just for fun.

Predictions for the year 2041 Made with Fillout, the best way to make forms, surveys and quizzes your audience will answer.

We've been taking a lot about whether our new baby will ever learn to drive. I love long bets, so we thought it'd be fun to put together a #survey about the state of the world when she turns 16.

It's short and fun, so hit us with your boldest predictions!

That sounds awesome! I'm definitely with you that there's opportunities for sites that are less explicitly commercial and more "indie" feeling. It's definitely the sort of thing I'd love to read.

That said, I'm always impressed with how well your Patreon seems to be doing, so who knows

I run a similar-ish site, but have been actively trying not to monetize it (since it's really just for fun and then I don't owe anyone anything). Plus I like the idea of a site that's not focused on metrics.

23.01.2026 11:27 👍 1 🔁 0 💬 0 📌 0

Sounds rough when you put it that way. 😅

I also wonder if a site that looks like that is even viable these days. With the popularity of video (both short and long) I wonder if a new RPS would even be possible. Second Wind are giving it a go, but they're heavy on video.

Not that I have the cash, but I'm curious how much of an investment you'd need for this sort of thing.

Love your site, BTW! I've linked out to it at least a few times from mine. 😄

The new definition of the kilogram will change the way we weigh everything On Friday, representatives from 57 nations will gather in a conference room in Versailles, France to redefine the kilogram. In other words: the way we weigh the world is about to change.

And what's worse, it was slowly losing mass!

Ha, I hadn't even thought about that yet. What a cute idea!

It's' time once again for my Favorite Media of the Year post!

I can't believe it's my 10th. I truly don't know where the time has gone.

Please check it out and let me know what your favorites from 2025 were!

Advent of Code 2025 Day 1: Secret Entrance A step-by-step Python walkthrough for solving Advent of Code 2025 Day 1.

Better late than never, but I've got a solution post up for #AdventOfCode 2025 day 1 in #Python. It turns out babies make you tired?? But we got there anyway.

It really depends what you liked about it!

Gloomhaven is a great co-op RPG, but there's much less story. Divinitiy: Original Sin 2 is by the same devs & has great writing, but is harder (but still very good).

There's tons of other co-op games that aren't long RPGs, too. Happy to recommend stuff!

Thank you! We'll do our best to savor it. 😁

See you all next year!

Fair! I'm going to do at least the next one to see if/how it really picks up. Cause I really have heard nothing but good things! But I'm sort of with you on the first one. My wife dipped out too

How'd you like Dungeon Crawler Carl?

I thought the first was decent but everyone who has read (or listened) says it picks up and they unanimously speed through books 2-7

Backpack Quest My journey to find the perfect all-purpose daily driver backpack.

The second post in my yearly theme series is live!

It's about my quest for the perfect backpack, which enables basically an infinite amount of comparison shopping. It all worked out in the end though.
