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! Maybe you want to weird out your fellow conference-goers as you turn a dry powder into a fully cooked meal with hot water and hot water alone!Links:Making dehydrated meals overview (Christine's Kitchen 0): [YouTube] [PeerTube]Backpacking chefDishwasher cooking (yes it is a thing)

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 the Overview section... it's actually fairly easy to understand!Some of the implementations discussed (though there are many more):MastodonPeertubePixelfedPleromaA lot has been written about Elon Musk's takeover of Twitter.

Terminal Phase! A space shooter that runs in your terminal!!! Who wouldn't be excited about that?Not to mention that it shows off cool features of Spritely Goblins... like time travel:Well, Terminal Phase has been Christine's fun/downtime project for the last few years, and one of the bonuses you can get for the reward tiers of donating to this podcast! And yet we've never done an episode about it! Given that a brand new (and much easier to install) release of Terminal Phase is coming out really soon, we figured now's a good time to talk about it!Links:Terminal Phase!Blogposts about Terminal Phase!Project announcement1.0 announcementTime travel debugging in Spritely Goblins, previewed through Terminal Phase1.1 announcementTerminal Phase was in a Polish "Linux magazine"!FOSS & Crafts' PatreonSpritely Goblins, a project of the Spritely InstituteBlast off!

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!A closer look...Actually, let's move that solar panel aside...Here's a better view of the cabinet with all the equipment attached:Here's what the van looks like if you come in the side door:Another, more diagonal view:Safety first!Window covers, custom fit!

The Spritely Institute (of which Christine is CTO) just announced its multi-year grant by the Filecoin Foundation for the Decentralized Web and gave a tour of its current tech! This is a big moment that's been in the works for a while, as Spritely moves hands towards real stewardship by a real nonprofit!Also also!

Morgan's out sick! And yet Morgan is still in this episode! And that's because this episode is the audio version of a 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! And relatedly, Christine and the Spritely Institute just published A Scheme Primer, which is more or less the text version of that presentation! The next live verison of the sheme tutorial will be hosted at Hack & Craft! Come this Saturday, July 16, 2pm-4pm ET (6pm-8pm UTC)! We're planning to record this one!Oh, and bonus Fructure gif:Links:The video version of this talkEpisode 47: What is Lisp?Wisp and its associated SRFI-119Fructure!!!

The amazing Sophie Jantak joins us to talk about how she makes pet portraits (including one she made for us!) using Blender's Grease Pencil. Hear about Sophie's process, why Grease Pencil is the right tool for her, and what her collalboration process is like on pet portrait commissions!

This episode is all about the Lisp family 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 McCarthyThe Evolution of Lisp by Guy L. Steele and Richard P. GabrielHistory of LISP by Paul McJonesWilliam Byrd's The Most Beautiful Program Ever Written demonstrates 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 machinesMIT'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 book Hackers (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.orgThe GNU manifestio mentions 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 IvoryRISC-V tagged architecture, plus this lowRISC tagged memory tutorial. (We haven't read these yet, but they're on the reading queue!)SchemeThere's a lot of these... we recommend Guile if 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 especiallySee this section of the Guile manual for a bit of... historyCommon Lisp... which, yeah there are multiple implementations, but these days really means SBCL with Sly or SLIMEClojure 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 kinda blew up his community so maybe use something else these days.Hy, always hy-lariousFennel, cutest lil' Lua Lisp you've ever seenWebassembly's text syntax isn't technically a Lisp, but let's be honest... is it technically not a Lisp either?!Typed Racket and HackettEmacs...

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 Actors is maybe the cleanest writeupThe Agoric Open Systems papers by Mark Miller and Eric Drexler are a good background into the underlying motivations that got Mark into distributed objectsmarkm-talks and markm-more-talks which are mostly about object capability security topicsAPConf keynote, Architectures of Robust Openness by 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 in When Encryption Was a Crime: The 1990s Battle for Free Speech in Software, part of a four part seriesRSAXanadu, Ted Nelson, and Computer Lib/Dream MachinesXerox 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 the Ode to the Granovetter Diagram paper 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 mentioned RSA, which is the first publicly published algorithm for public key cryptography. These days most public key cryptography uses elliptic curves instead. 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 Answers has been a useful page, but the cryptography world keeps moving!

This week we’re talking about Repetitive Strain Injuries (RSI). Christine and Morgan tell their stories bout over-using their wrists from programming (prodded along by an injury) and writing academic papers respectively. We discuss what you can do to treat or minimize the effects of these injuries then cap it off with a discussion of RSI gloves including Morgan's Free Soft Wear RSI glove pattern.Repetitive Strain InjuriesMorgan's RSI gloves articleYour Wrists Hurt, You Must Be a ProgrammerIt's Not Carpal Tunnel Syndrome book (there are probably better resources out there now, this is what Christine read a decade ago)WorkraveSome RSI exercises that Christine thought were effective (old, but archived on internet archive...
