How do you survive in a world that is no longer optimized for making your own clothing when you suddenly find that modern conveniences no longer accommodate you? As a textile historian, Morgan has been ruminating for years about women’s contributions to the domestic economy, the massive time investment of producing clothing for a family, and the comparative properties of different textile fibers. These research interests were informed by a lifetime of sewing and other fiber crafts. None of this experience, however, properly prepared her to face the reality of needing to rely on her own hands to provide large portions of her own wardrobe. Guest co-host Juliana Sims sits down with Morgan to talk about how, in the wake of a recently developed allergy to synthetic fabrics, she now finds herself putting that knowledge of historical textile production to use to produce clothing that she can wear. Links and other notes: Morgan presented this as a (much shorter) talk at the Dress Conference 2023 Slides from the presentation Morgan's Dissertation, which we also covered RSI Glove Pattern The quote that Morgan somewhat misremembered about a woman preparing wool before the winter: "A thrifty countrywoman had a small croft, she and her sturdy spouse. He tilled his own land, whether the work called for the plough, or the curved sickle, or the hoe. She would now sweep the cottage, supported on props; now she would set the eggs to be hatched under the plumage of the brooding hen; or she gathered green mallows or white mushrooms, or warmed the low hearth with welcome fire. And yet she diligently employed her hands at the loom, and armed herself against the threats of winter." -- Ovid, Fasti 4.687-714

In yet another deep dive into yet another weird hobby of Christine's, we talk about how to make your own dehydrated meals! Why the heck would you want to do this? Well, maybe you want more consistent or dietary needs friendly travel food! Maybe you want to go camping or hiking! Maybe you're sick of deciding what's for lunch and you just want to scoop a cup of meal out of a jar on your desk every day!

Look, this is admittedly kind of a fluff episode. Have we linked to Worse is Better before? We did? In the lisp episode? And here's the Terminal Phase episode

Twitter is burning, and people are flocking to the fediverse. Is the fediverse ready though? How did we get here? Where should we be going? Since Christine is co-author of ActivityPub, the primary protocol used by the fediverse, Morgan decides it's time to get Christine's thoughts recorded and out there... so we hop in the car as we talk all about it! Links: ActivityPub, the protocol which wires the federated social web together, of which Christine is co-author! Be sure to check out theOverview section... it's actually fairly easy to understand!

Morgan and Christine walk through their (well, Morgan's) renovation of a cargo van into a campervan. This is a very crafty episode, but we do work in a few analogies to some FOSS (and open hardware) things! Show notes at the end, but how about a quick visual van tour? Back of the van, wide open!

Morgan's out sick! And yet Morgan is still in this episode! And that's because this episode is the audio version ofa talk by the very same name from FOSDEM 2022, co-presented by Christine and Morgan! But since Morgan isn't here, Christine fills in, and also gets a bit silly. HACK AND CRAFT SCHEME TUTORIALS!The last live scheme tutorial went really well!

This episode is all about theLispfamily of programming languages! Ever looked at Lisp and wondered why so many programmers gush about such a weird looking programming language style? What's with all those parentheses? Surely there must be something you get out of them for so many programming nerds to gush about the language! We do a light dive into Lisp's history, talk about what makes Lisp so powerful, and nerd out about the many, many kinds of Lisps out there! Announcement: Christine is gonna give an intro-to-Scheme tutorial at our next Hack & Craft! Saturday July 2nd, 2022 at 20:00-22:00 ET! Come and learn some Scheme with us! Links: Various histories of Lisp: History of Lisp by John McCarthy The Evolution of Lisp by Guy L. Steele and Richard P. Gabriel History of LISP by Paul McJones William Byrd'sThe Most Beautiful Program Ever Writtendemonstrates just how easy it is to write lisp in lisp, showing off the kernel of evaluation living at every modern programming language! M-expressions (the original math-notation-vision for users to operate on) vs S-expressions (the structure Lisp evaluators actually operate at, in direct representational mirror of the typically, but not necessarily, parenthesized representation of the same). Lisp-1 vs Lisp-2... well, rather than give a simple link and analysis, have a thorough one. Lisp machines MIT's CADR was the second iteration of the lisp machine, and the most influential on everything to come. Then everything split when two separate companies implemented it... Lisp Machines, Incorporated (LMI), founded by famous hacker Richard Greenblatt, who aimed to keep the MIT AI Lab hacker culture alive by only hiring programmers part-time. Symbolics was the other rival company. Took venture capital money, was a commercial success for quite a while. These systems were very interesting, there's more to them than just the rivalry. But regarding that, the bookHackers(despite its issues) captures quite a bit about the AI lab before this and then its split, including a ton of Lisp history. Some interesting things happening over at lisp-machine.org The GNU manifestiomentions Lisp quite a bit, including that the plan was for the system to be mostly C and Lisp. Worse is Better, including the original(but the first of those two links provides a lot of context) The AI winter. Bundle up, lispers! Symbolics' Mac Ivory RISC-V tagged architecture, plus this lowRISC tagged memory tutorial. (We haven't read these yet, but they're on the reading queue!) Scheme There's a lot of these... we recommend Guileif you're interested in using Emacs (along with Geiser), and Racket if you're looking for a more gentle introduction (DrRacket, which ships with Racket, is a friendly introduction) The R5RS and R7RS-small specs are very short and easy to read especially See this section of the Guile manual for a bit of... history Common Lisp... which, yeah there are multiple implementations, but these days really means SBCL withSly or SLIME Clojure introduced functional datastructures to the masses (okay, maybe not the masses). Neat stuff, though not a great license choice (even if technically FOSS) in our opinion and Rich Hickey kindablew up his communityso maybe use something else these days. Hy, always hy-larious Fennel, cutest lil' Lua Lisp you've ever seen Webassembly's text syntax isn't technically a Lisp, but let's be honest... is it technicallynot a Lisp either?! Typed Racket andHackett Emacs... Lisp?... well let's just give you the tutorial! The dreams of the 60s-80s are alive in Emacs. The Many Faces of an Undying Programming Languageis a nice little tour of some well known Lisps. Actually, wejust did an episode about Emacs, didn't we? Digital Humanities Workshops episode We guess if you wanted to use Racket and VS Code, you could use Magic Racket?! We dunno, we've never used VS Code! (Are we out of touch?!) What about for Guile?! Someone put some energy intoGuile Studio! Hack & Craft!

Calling all programming language nerds! Distinguished computer scientist Mark S. Miller (presently at Agoric) joins us to tell us all about distributed object programming languages and their history! We talk about actors, a bit of Xanadu, and little known but incredibly influential programming languages like Flat Concurrent Prolog, Joule, and E! Actually there's so much to talk about that this episode is just part one! There's more to come! Links: The actor model(the core of which is sometimes distinguished from modified variants by as being called "the classic actor model"). Long history; Tony Garnock-Jones' History of Actorsis maybe the cleanest writeup TheAgoric Open Systems papersby Mark Miller and Eric Drexler are a good background into the underlying motivations that got Mark into distributed objects markm-talksandmarkm-more-talkswhich are mostly about object capability security topics APConf keynote, Architectures of Robust Opennessby Mark S. Miller (YouTube copy) Mark diagraming a (certificate based) object capabilities flow at Rebooting Web of Trust 2017 (when Mark and Christine first met!) The history of Mark and company performing civil disobediance to make cryptography available to everyone is discussed inWhen Encryption Was a Crime: The 1990s Battle for Free Speech in Software, part of a four part series RSA Xanadu,Ted Nelson, and Computer Lib/Dream Machines Xerox PARC, which is where the Vulcan group happened (which is hard to find information on, sadly). Mark mentions some of his colleagues who worked with him in the Vulcan group, including Dean Tribble (who worked on Joule, see more below) and Danny Bobrow who is famous for his groundbreaking program STUDENT (Natural Language Input for a Computer Proglem Solving System is an incredible read, detailing a program (written in lisp!) which could read algebra "word problems" written in plain English and solve them... in 1964!). Flat Concurrent Prolog... it's tough to find things about! Presumably here's the paper Mark mentioned that Dean lead on Flat Concurrent Prolog from the Vulcan group which lead to Joule's channels. A bit more on (go figure) erights.org! The Joule manual is still a very interesting read, if you can find the time. Talks about channels in depth. Here's the Communicating Sequential Processes book by Tony Hoare, quite a nerdy read! On capabilities and actors... we'll get to this more in the next episode, but for now we'll leave theOde to the Granovetter Diagrampaper here (it's a truly amazing document!)

In this episode we give a very (very) high level introduction to cryptography concepts. No math or programming background required! Links: Crypto 101, probably the BEST book for learning about cryptography concepts. And a relevant talk from PyCon! We mentionedRSA, which is the first publicly published algorithm for public key cryptography. These days most public key cryptography useselliptic curvesinstead. It's possible that in the future, something else will be recommended instead! Playing around with GnuPG can be a great way to learn about cryptography as a user, but... it's also not the easiest thing to learn either, and we don't personally believe that GPG/PGP's web of trust model is a realistic path for user security. (But what we recommend instead, that's a topic for a future episode.) Still, a useful tool in all sorts of ways. Mixing and matching these things at a low level can be tricky, and unexpected vulnerabilities can easily occur.Cryptographic Right Answershas been a useful page, but the cryptography world keeps moving!
