Peat is Urbit’s first backup utility.  Prior to Peat, there was no easy way to backup content from groups from your ship aside from copying your entire urbit.  Peat makes it easy to export all your data from Groups, which uses the graph-store data structure, and in the future will provide support for the new structure in Tlon’s upcoming Groups revamp.

Urbit Foundation Executive Director Josh Lehman and Epicenter host Brian Crain have a wide ranging discussion on Urbit's history and future.

Josh Lehman: Urbit – The Peer-to-Peer Network Re-Decentralizing the Internet


~littel-wolfur will be talking about the history and state of %khan, a new thread orchestrator vane in Urbit. He will go over its usage in apps like the discord bot by ~midsum-salrux, how it makes thread interaction much easier, and how future %khan clients will make native noun communication possible. There will be a simple demo of a naive client at the end of the talk.

~littel-wolfur is a longtime Urbit contributor currently working on devex for smart contracts at Uqbar.


Neal Davis

Developer Call: The Future of %khan


Join us on September 15th to talk to ~pilwyc-fastec about Communal Computing and the Internet of Things (IoT). ~pilwyc-fastec has been studying how Urbit and Internet of Things (IoT) devices can complement each other securely. Connected devices open up new frontiers of integration and automation, but have tradeoffs in security and control worth considering as users and developers.

~pilwyc-fastec is an IoT hobbyist, smart home enthusiast, Alexa skill builder, and most recently was product manager for the identity platform, biometric recognition machine learning, and voice assistant integration for Facebook’s Portal. He recently published [a blog post on Communal Computing](https://urbit.org/blog/smart-home-of-the-future).

We'll discuss how Urbit and Communal Computing ideas complement each other, and where work remains to be done. The smartest home is one you still control yourself.

Holium is one of the rising stars in the Urbit Community. Earlier this year they launched the Ballot app and will have much more to show at [Assembly 2022](https://assembly.urbit.org). Holium is focused on building a full OS experience around communities and DAOs, where the software that the community runs on — think chat, calendar, files, voice and video calls — are integrated in the computing environment like never before. Developers and especially fresh Hoon School grads should keep their eyes on Holium's roadmap, as opportunities to work with them are dropping regularly. On this call, Trent (~lomder-librun) will tell us all about their plans, their roadmap, and how you can help out.

Trent has worked in software for almost a decade. He spent his first 3 years in the corporate world before building various startups. A recent Urbit convert, he believes in a pro-human future and is fighting for humanity to keep its soul as we enter the neon age.

What is the Urbit??

Philosophers, mathematicians and other timewasters have pondered this tough question for aeons. Many went mad, others grew long beards or even buried themselves alive, thinking the riddle unsolvable. So did we... until now.

Urbit Brisbane are proud to announce that we finally have found an answer: yes, we have figured out what is the Urbit!!

We'd like to share this important knowledge with you, so join us among the fair hills of St Lucia this Friday night. The Secret Venue will be announced on Friday arvo. RSVP and stay tuned to the event page so you don't end up walking around Guyatt Park accosting joggers for clues.

Come along and learn about the Urbit with us. You will gain access to an eldritch power far beyond the frail grasp of worldly things. If that isn't enough to tempt you, we also have beers and pizza with your name on them.\*

As many of you know, Urbit runs best when hosted, seeing that it's a server and all. The problem of course is that hosting an Urbit ship isn't the easiest of things to do for most people. Hosting Urbit ships in production is actually pretty tough though—doing it right requires wrangling the complexity of traditional "Earth" infrastructure in addition to a strong sense of how Urbit works.

In this call we're joined by Brendan Hay, the lead behind Tlon Hosting, and Lukas Bühler of UrbitHost, in what's sure to be an entertaining and informative conversation. Bren and Lukas have both been the masterminds behind their respective hosting architectures, and were somewhat surprised to learn that they'd independently settled on highly similar architectures.

This will be an unscripted conversation that's sure to span a gamut of topics including, but not limited to: the unique technical challenges of hosting Urbit ships, the upcoming %khan vane, Kubernetes operators, product roadmaps, custodianship of (or plans to do away with) private keys, and probably a ton more.

Hosted by Josh Lehman, the Director of the Urbit Foundation.

Developer Call: The Urbit Runtime and its Future


The Urbit community has grown at a rapid clip throughout 2021. There are so many exciting things going on that it's hard to convey them all, even with Developer Calls happening every two weeks. This event will function as a virtual "mini-conference" where we'll give a series of important and exciting announcements, including both formal and informal talks from many members of our community.

Here's a rundown of what we'll be discussing:

## Introduction: State of the Network

_12:00 PDT, Josh Lehman_

Urbit is under heavy, active development by both Tlon and a wide range of contributors. Josh Lehman will discuss some of the most important areas of work being undertaken, provide a picture of where Tlon and community efforts are going in the future, and even has a few exciting announcements to make.

## Taisho, Urbit's Port City

_~12:20 PDT, Hunter Miller_

Piloting an Urbit ship requires expertise that many lack. To achieve the rich and prosperous ecosystem we've all envisioned requires making that journey easier. In this talk, Hunter Miller introduces a new way for users to join the network with minimal effort.

## Keynote: The Revenge of Teleology

_~13:00 PDT, Justin Murphy_

Teleology—or inquiry into ultimate ends—has been out of fashion since the seventeenth century, when Francis Bacon said that, “like a virgin consecrated to God,” it “produces nothing.” I argue that the digital revolution is inverting Bacon’s claim. Baconian instrumentalism is now suffering from diminishing returns—it is what the youth today call a Boomer Ideology. Rather, the greatest gains are going to individuals and communities with teleological attitudes. This talk will observe some examples and present a model consistent with the observations. Bitcoin inquires after the telos of money, the most winning independent “content creators” inquire after the telos of media, and Urbit inquires after the telos of personal computing.

## Lightning Talks

_14:00 PDT, you?_

After the scheduled talks we'll break out into a series of 30 minute talks led by community members. There will be up to three talks given in parallel at each of 14:00 PDT, 14:30 PDT and 15:00 PDT (so nine talks total).

If you'd like to give a talk, please use [this form to sign up](https://airtable.com/shr0Xmqcv1HSy47EP).

Some exciting work has been going on behind the scenes to provide the foundation for 3rd party software distribution. In this talk Phil (~wicdev-wisryt) and Raghu (~sovmep-ripsum) will discuss the work they've been doing to clay to provide "virtual desks"—an integral part of the infrastructure needed to have safe, generic software distribution.

Raghu is a software engineer at Hudson River Trading who is perhaps best known for his work on ucal, the Urbit calendar application. The work he's doing with Phil on virtual desks is being done through our Scholarships program, in which community developers pair up with Tlon infrastructure engineers to work on infrastructure projects. We'll spend some time at the beginning of the call to introduce Raghu and hear about his experience working on the Urbit kernel.

As usual, there'll be an opportunity to jump on the call with us afterward to ask questions and hang out.

Urbit provides a powerful and extensible platform for all kinds of app development. It can serve as a general-purpose datastore, decentralized network, and identity solution for a variety of front-end applications. The client that ships with Urbit, Landscape, provides one example of the kind of applications that can be built on the platform. However, other developers can use the same tools used to create Landscape to power their own interfaces and clients for Urbit.

Tyler Brown Cifu Shuster (~radbur-sivmus) has worked with the Landscape team over the past few months to extract these tools into reusable Javascript packages. In this talk, he will explain how to use them to develop a client for Urbit independent of Landscape. He will cover the basic lifecycle of a client and explain how Javascript interface and state frameworks pair with Urbit's data model.

This talk should enable anyone familiar with modern Javascript development and HTTP grammar to build an application on top of Urbit without writing any back-end code.

Landscape was an experiment. Now it’s Tlon's flagship client for the Urbit project: a product, a full-stack application, spread across a variety of Gall agents and libraries, lighting the way forward against the dwindling unknowns in the reality of Urbit userspace development and distribution.

Matilde Park, Landscape team lead, talks about the distinctions between the Landscape product and basic Urbit development, and the significance of building Landscape for Tlon — the role of “high-pressure experiments” in forcing our computer toward something rock-hard, diamond-perfect. With a few examples of ongoing deployments, she also outlines the problems being solved right now and the ones still a touch further out.

As usual, join us after the talk on the call to ask questions and hang out.

Urbit engineer Philip Monk will be discussing the solution space to scaling Azimuth, the infrastructure for Urbit ID that's built on Ethereum.

Unless you're living under a rock, you know that Ethereum is thoroughly congested and, as a result the cost of working with it is quite high. Most pertinently for Urbit, this means that the cost of bringing new planets onto the network is unacceptably high.

Phil has been doing a ton of research for the past few months on different approaches to scaling Azimuth. In this talk, he'll lay out the what's been explored so far, the relevant considerations for Urbit, and the emerging solutions that are being pursued.

As usual, this talk will feature a presentation, a Q&amp;A period and a follow-up video call that anyone from the audience can join.

See you there!

Tlon Engineer Philip Monk is interviewed by Poprox in an "Architectural Idea Maze" discussion, where Phil will discuss the choices made, and possibly more importantly, the choices _not_ made in the design of a component of Urbit. In this discussion, Phil will be focusing on subscriptions in all their forms throughout Urbit.

Developer calls are focused on the technologies that underpin Urbit, from the top of the stack to the very bottom. They’re an opportunity for the people developing and contributing to Urbit to share their knowledge and expertise, including things that typically don’t make it into the docs, such as how and why Urbit works the way it does.

The livestream will be held on YouTube, and a group video call will be made available via Google Meet after the talk for casual discussion and in-person conversation.

This call will feature a discussion by well-known developer in the Urbit community, ~timluc-miptev. ~timluc will be discussing the work he's been doing to provide access to a Bitcoin full node, which will enable Urbit ships to make Bitcoin payments to other ships. More generally, he'll be discussing the patterns that he's using to manage an Urbit ship's connection to externally-running infrastructure, and how access to that infrastructure can be provided to other Urbit nodes.

Developer calls are focused on the technologies that underpin Urbit, from the top of the stack to the very bottom. They’re an opportunity for the people developing and contributing to Urbit to share their knowledge and expertise, including things that typically don’t make it into the docs, such as how and why Urbit works the way it does.

The livestream will be held on YouTube, and a group video call will be made available via Google Meet after the talk for casual discussion and in-person conversation.


Developer Call: Injecting External Services into Urbit


This call will feature a discussion by Tlon engineer Mark Staarink, also known as ~palfun-foslup, about writing an HTTP BitTorrent tracker and command line app in 1500 lines of code.

Developer Call: Graph Store


We've been busy building, testing and refining — and now it's time to show off what we've been up to.

We're going to do a live demo of Tlon's Urbit hosting solution, check out some of the new features of Landscape and generally catch up on what both we (at Tlon) and the community have been up to.

Since the OS 1 launch, back in April, we've been living on Urbit day to day. Urbit has gotten gotten a lot faster, more reliable and nicer to use. Most importantly, we've got an easy way for friends to come join us without running their own node. We're really excited to let people explore what's possible with Urbit and build communities without ever touching the command-line.

Lately, Urbit has been having dangerous amounts of fun online. So we got thinking, 'Wouldn't it be smart to try having fun offline as well?' Thus, we invented something totally new: an offline chatroom.

There's no lesson per-se, think of it more like an 'independent projects' class. A few of us will be around to help you get started working on whatever you're interested in. It's completely fine if you're new to the language. We're going to start with 20 spots so we can help everyone individually.


Come, bring your laptop, and we'll get you started building things in Urbit's language — Hoon.
