When we started working on Positron, we began by asking "what did we always want to do in RStudio, but couldn't"? Years of community upvotes on RStudio's issue tracker helped us form that wishlist. Here's how some big ideas made their way to Positron: opensource.posit.co/blog/202…

Got the new Windows 11 update, and I have to say it's pretty handy to know what I'm going to download tomorrow

Earlier this year, I gave a keynote at posit::conf(2025). It was meant to be a talk about Positron, but as I was writing it, it took a left turn through the history of RStudio and into the philosophy of tool design & how to build stuff for people. youtube.com/watch?v=tGrePGYj…

Hey look, a smartwatch that doesn't need charging every day, reads better outdoors, doesn't send data to big tech companies, and has an open source OS! This is so fun. Thanks, @ericmigi, for bringing @Pebble back.

Disappointed in @Apple quality today. I have a 2013 MacBook that still works. Today, I learned that my 3 year old, $3,500 MacBook has a failed logic board and Apple recommends "recycling" it. It's 3 months out of Apple Care. You don't make 'em like you used to, @Apple .

5 year old: What's happening, big guy? Me: Don't call me "big guy." It's kinda weird. 5 year old: You'll get used to it, big guy.

Congrats @standardebooks on this milestone! (And on formatting the full text of Ulysses. Good heavens.) If you've ever waded through 954 poorly formatted $0.99 copies of "public domain" works on Amazon, you know that this organization is doing the Lord's Work.

12 year old: *shows me an elaborate PowerPoint presentation he made for a game show called "The Rice is Right", in which contestants must watch a short, close-up video clip of a granular substance and guess whether it is rice* Me: 12 year old: This idea came to me in a dream

Someone used one of my e-mail addresses to sign up for @Match, with the result that I'm now getting a marketing email from them 3-4 times a day. Didn't we agree to send people emails to confirm their subscriptions? I thought we agreed to that.

Buck up, baby blowfish. Just puff up bigger than your sadness and scare it right off. That's the only way to live in the awful old ocean. -- @catvalente, Radiance

While I identify as a Christian, I think the #HeGetsUs #SuperBowl ads were awful. I don't think Jesus needs or wants our slick marketing campaigns. It cheapens the Man of Sorrows to put him on billboards and bumper stickers. He isn't a product.

If you're working on software meant to last a long time, use long, unique names for all non-local identifiers (functions, classes, etc.). Future You is gonna need to find references, and Future You is only going to be able to use "find string".
