This episode is about the paper Technical Dimensions of Feedback in Live Programming Systems by Josh Horowitz. [THIS SPACE INTENTIONALLY LEFT BLANK] [SERIOUSLY, IF YOU WANT SOMETHING HERE, WRITE IT YOURSELF] [NO PROMISES. MAKE IT GOOD] It's a solid episode — that's my take. You should listen to it instead of reading about it. And then give us your take. Links $ Gang, I'm sorry this episode is months late. It was a real doozy! But also, the bonus episodes over on our Patreon have been getting wildly ambitious. I did an insanely edited 54-minute video about The Browser Company. We had William Taysom over to share a deep critical analysis of The Witness. Jimmy and I shared what we'd do with our lives if we weren't doing computer stuff. And most recently, we spilled the design tea on two recent projects we've been working on — Jimmy's Whiteboard visual programming system, and Tenfold from Ink & Switch. If you like the FoC podcast, you'll get so much more of it for $5/month at feelingoff.com. Audio Hijack — this is the program we use to record the podcast. It has "Canadian Juice", which is a joke only Lu will get, but Lu isn't going to read this. But you all know what "juice" is, right? It's what Andrew Blinn does better than anyone, and he IS reading this. He fucking better be. Am I narrowcasting? Jimmy mentioned Notes from the Underground. I haven't read it, so I can't add snark. Sorry. We're making backend changes! Stay tuned. The new website for this podcast will be feelingof.com. You should check out that website, cool stuff there, and they have a podcast. The Hest podcast, which Ivan has always self-hosted (so to speak), is, basically, 38 episodes of Ivan describing what he's devoting his life to, one episode about the combat loop of the video game Death Stranding, and one episode about getting smaller and smaller forever, but make it music and about Ivan's misspent youth. If you're reading this and you haven't listened to it, what the hell are you doing! You'll love it so much! PlayBook is the project that the Programmable Ink folks at Ink & Switch have been working on since January 2024. Ivan is one of those folks. I'm one of those Ivans. Specifically, this is "the show notes writing Ivan". Have you met? He writes the show notes. I commentate on his work. This… paper(!)… was originally presented as a talk at LIVE PROG — which is almost a FOUR FOUR — in 2024 as a talk called Definitions & Dimensions of Liveness. Jimmy and Lu and I were in the room! Maybe that's the last time we'll ever be in the room. (Did you listen to the free 2025 holiday spectacular?) You sat along the fire… you saw the light… you saw. You're Sigur Rós, you're so. Why am I crying? Inventing on Principle — do we need to link to this? If you're reading these show notes and you haven't watched this talk, email hello@feelingof.com and I'll give you a virtual hug because you're listening to our podcast without getting, like, any of the jokes? Observable — same snark as previous Projection Boxes — now this one, I hadn't heard of, but if you have heard of it reach out and tell me about it so that I can be in on our jokes.

We've renamed the podcast and community — we are now the Feeling of Computing! Here are some thoughts about the motivation to rename and the choice of new name. It's a small change, but it feels meaningful and clarifying. The new name better fits what we've been doing all along, and sets us up for the next decade of this community. The new name reminded us of The Computer is a Feeling, a document (of some definition) by Tim Hwang and Omar Rizwan. Unlike our usual selections, which are crouton-dry and tiring, this one is basically a 1-pager, quick and fun — you should totally give it a glance and see what you make of it, before Jimmy and I tease it apart and lawyer over the many nuances. This piece makes us question what the computer means in our lives, and how that may have changed over time. Light on specifics and arguably steeped in nostalgic yearning, its series of declarative statements come out more like broadly probing questions. Is the computer feeling possessed only by those who remember the time before the internet? Are computers even required? What does feeling this feeling elicit one to do? We answer at least one of these questions. "But you can't trust them, they're podcasters," said everyone ever, "you've got to feel it for yourself." Links $ While these main Feeling of Computing episodes are, in a word, infrequent, the bonus episodes over on our Patreon — Feeling Off — arrive at a dependable regularity! Why, in the time since we recorded this here episode, we've released two (2) bonus episodes. The first was a unruly deep tangent Jimmy and I fell upon right smack in the middle of this very episode, and then excised out — That's Shakespeare — about code.org, whether the "everyone should learn to code" movement is actually about literacy, the backlash to this movement, and our personal feelings on it all. Then in December we shared our annual end-of-the-year spectacular with games, awards, music, spelling, men who are spiders, and our predictions about the near and distant future — All of the False Ones — free free free for download, no patronage required. The old name is cursed. The old name might have been inspired by Bret Victor's talk The Future of Programming, but the vibe of the community is probably closer to Inventing on Principle. The new name invites us to reflect on the way our tools make us feel. For instance, Kid Pix was a quirky, playful drawing program designed for younger users which had its heyday in the 1990s when Ivan was a younger user, and it gave him some pretty specific feelings at the time. (Also, in the time since recording this episode, Ivan dug up a Snow Leopard iMac from the sedimentary rock and installed KidPix Studio 4, and his 6 year-old daughter has been having a blast with it.) One Piece is a manga and anime that's pretty popular, but perhaps off-topic for our community. Did you know about our virtual meetups? Every month we have people showing off their work, and it's been fantastic to see the wild variety of creative programming projects built by members of our community. We share the details of upcoming meetups in the #announcements channel on our Slack, and publish them in this Luma calendar. You should come! The feeling is still present, in your time, as it was in ours You can build computers out of water, if you want Sim City 3000 was released in 1999, and gave Jimmy the computer feeling. (Ivan played Sim City 2000 back in 1997-ish, and got pretty good at typing the word "FUND", before learning that this didn't actually give you free money and instead gave you a bond.) When Ivan says "go to six
One of the biggest goals of this show — our raisin detour, if you will — is to encourage people to look at computer programming differently. It's not just a job, or a way to make the computer do what you want. Code isn't just the material you sculpt into apps and games and websites. The very act of programming itself, and the languages we make and use to do that programming, reflect who we are as people. Programming languages say something. Esolangs — esoteric programming languages — are programming languages created for these more self-reflective purposes. To some, they're defined by what they're not: not for serious use, not for education, not for efficiency. To others, they're a bunch of funny jokes that people can commiserate through after suffering the steep learning curve of becoming a programmer. A few find in them an opportunity to explore strange computational models, or baffling syntax designs. But is there more to them? Could there be? In this episode, we're discussing a preprint of the paper Let's Take Esoteric Programming Languages Seriously by Jeremy Singer and Steve Draper, and struggling with what it even means to give esoteric languages their due. Links $ Each of these episodes is a labour of love. If you appreciate that labour, slip us a five on Patreon. As is the norm, you'll get a second RSS feed with a bonus episode each and ev-er-y month. Except this month, there's actually two (2) bonus episodes, for the simple reason that this podcast swells with bubbles of hot waxy fluid that spill the container of my Ableton Live when they pop. The first pop is a half hour cut from this esolangs ep, the three of us brainstorming esolangs we'd enjoy, super casual and playful, perfect for building your parasocial podcast relationship, you'll love it. The second bonus, as I'm sure you've been expecting, is three hours of Jimmy and I relaying our experiences with Silksong, unpacking its few contentious design decisions, fawning over exquisite details, the good shit. So yeah, hand us one hundred nickles, help Ivan repair his basement, enjoy more of… whatever this is. Daniel Temkin 🛌 😴💤😘 esoteric.codes Daniel's new book, Forty-Four Esolangs Joana Chicau The Less Humble Programmer Esolangs Wiki Entropy, an esolang by (total dreamboat) Daniel Temkin Unnecessary, the 4:33 of esolangs, by Keymaker Turing Paint by Byron Knoll, which is similar to Brian Silverman's Wireworldand Lu's Cableworld Ivan's Visual Programming Codex, a collection of all the cool visual programming things Ivan has come across in his travels. Riskopoly — The Game of Capitalist Imperialism! Fanny#In_slang Brainfuck and Whitespace are two canonical esolangs. Our episode on Structure of a Programming Language Revolution, which includes extended discussion of Ivan's father-in-law's lookalike. Dreamberd is one of Lu's Esoteric programming languages, which has a (let's just say) "interesting" relationship with AI. The Story of Mel Piet, Befunge, and Malbolge are more classic, oft-cited esolangs. Fractran deserves special mention, since the language is comprised entirely of fractions, which is pretty neat. MarkovJunior also deserves special mention. Seriously, go look at the examples. Wild stuff. It's by Maxim Gumin, who also did the famous <a href="https://github.com/mxgmn/WaveFun

[…] It is the breathless confrontation with one’s vulnerability, one’s perilousness, one’s smallness, pitted against a sense of sudden shocking discovery; it is the redemptive artistic act that stirs the heart of the listener, where the listener recognizes in the inner workings of the song their own blood, their own struggle, their own suffering."

In the academic field of programming language research, there are a few prestigious conferences that you must present at to advance in your career. These conferences are rather selective about which presentations they'll accept. If your research work involves proving formal properties about a programming language, you'll have their ear. But if your work looks at, say, the human factors of language design, you might as well not bother applying — and thus, not bother pursuing that work in the first place. Why is the formalistic, systems-focused work elevated, and the human-focused work diminished? And what are the downstream consequences, the self-reinforcing feedback loops that come from this narrow focus? In this episode we discuss a paper by Felienne Hermans and Ari Schlesinger titled, A case for Feminism in Programming Language Design. It applies the lens of intersectional feminism to reveal a startling lack of "Yes, and…" in academic computer science, where valuable avenues of inquiry are closed off, careers are stifled, and people are unintentionally driven away from contributing to the field, simply because their passions and expertise don't conform to a set of invisible expectations. Through heartbreaking personal anecdotes and extensive supporting references, the paper makes the case that there's a lot of high-value greenfield work to be done, and people who would love to do it — but we will need to collectively identify, understand, and then fix a few broken incentives before it'll happen.

"Is the whole universe a computer?", ask Jack Copeland, Mark Sprevak, and Oron Shagrir in chapter 41 of the book The Turing Guide. They split this question in two, first asking whether the universe itself is a computer, then whether the universe could even be computed. These are lofty, unanswerable questions, sure, but they encroach on our territory — philosophy, automata, nonsense. So, in our usual reverent style and with attentive pacing, the three of us explore the paper, the questions, the answers they choose to highlight, and even share a few perfectly reasonable answers of our own.

Alexander Repenning created AgentSheets, an environment to help kids develop computational thinking skills. It wrapped an unusual computational model with an even more unusual user interface. The result was divisive. It inspired so many other projects, whilst being rejected at every turn and failing to catch on the way Scratch later did. So in 2017, Repenning published this obit of a paper, Moving Beyond Syntax: Lessons from 20 Years of Blocks Programming in AgentSheets, which covers his findings over the years as AgentSheets evolved and transformed, and gives perspective on block-based programming, programming-by-example, agents / rule / rewrite systems, automata, and more. This is probably the most "normal" episode we've done in a while — we stay close to the text and un-clam many a thought-tickling pearl. I'm saying that sincerely now to throw you off our scent the next time we get totally lost in the weeds. I hear a clock ticking. Links $ Do you want to move beyond syntax?
