We look at the design of Volturno, a streaming engine with exactly-once processing, to illustrate why Unison Cloud is a great enabler for distributed systems builders.

Sometimes you need to search for a string fragment in your codebase, like when debugging an error message. In other languages, you might reach for a tool in your text editor to search for substrings, but in Unison we use the `text.find` command. In this quick demo, I’m using `text.find` to track down a stray SQL statement in an application’s repository tests. Enter `help text.find` in the UCM to learn more.

This video covers the basics of starting the Unison Codebase Manager (UCM) and writing your first bits of Unison code in a scratch file. We walk through: * Installing Unison on your system (Mac, Linux, or Windows) * Starting the UCM in a working directory * Creating .u scratch files and ensuring the UCM is watching for changes Helpful links: * Install Unison here: https://www.unison-lang.org/docs/quickstart/#step-1-install-unison * Get the UCM Desktop app: https://github.com/unisonweb/ucm-desktop/releases * Join the Unison community: https://www.unison-lang.org/discord

A walk-through of the process for installing a library dependency and upgrading it. * `lib.install` downloads the library into the `lib` namespace. * `ls lib` will show the current dependencies in the project * `upgrade` with no arguments opens up a version picker. Select the old version first, then the new one. Simple changes can be propagated without developer intervention; more complicated upgrades will prompt the UCM to create a branch for the upgrade process and open up the impacted terms in a scratch file. The resolution process follows the standard workflow for updating Unison code, described here: https://youtu.be/8lCDSCm_rGA.

Unison comments are not saved as a part of the function, so they can be used as temporary notes while working, however, they do not persist in the codebase.

Algebraic effects are not just a research concept anymore. You can use them in real software, today. Here's why you'd want to do that, in order of importance.
