Yep, we already have basic support for versioning.
The foundation of our approach is to have a versioned, documented schema shared among clients. Every write down to the individual attribute level is persisted with a schema version. We're already several versions in, and indeed think it's healthy to get experience with version updates frequently so that it's not an unusual occurrence.
Currently we use this schema to interpret / coerce values as needed at read-time. For example we see an attribute has schema version 1, and know that it should be interpreted in the sense that we meant as of version 1. In the future, we may also choose to write out updates for "migrations" where that'd be helpful. So that e.g. instead of having to re-interpret values for older version 1, we'd right out an update to he attribute that overwrites the old value and updates the version tag to e.g. 3.
We do think lenses are interesting and the lab from which we spun out has done some good work with them: https://www.inkandswitch.com/cambria/. They're just a bit complex for our modest needs re: schema versioning at this time.

This post was scraped from my old technical blog: http://web.archive.org/web/20100423003857/http://mmcgrana.gi...
Looks like the site has a few other scraped posts as well.
FWIW I no longer use this exact noprocrast(1) approach to avoiding procrastination, but do apply the same basic idea.

Muse | Remote | iOS and Systems Engineers | https://museapp.com
Muse is an iPad app to empower freeform, creative thinking. The company spun off from our industrial research lab (https://www.inkandswitch.com); we’re taking the novel interface approaches and technical ideas developed in that setting and turning them into a real-world product.
Learn more about Muse:
- Conference talk by a founder: https://www.youtube.com/watch?v=A_fe2c6IUUo
- Article by the team: https://www.inkandswitch.com/muse-studio-for-ideas.html
We’re hiring one engineer to join our all-remote team of four, with either of these two profiles:
- iOS Engineer: https://getmuse.app/ios-engineer
- Systems Engineer: https://getmuse.app/systems-engineer
We aim to be a small, independent business that optimizes for building an uncompromising product and that’s a rewarding place to work.
If you're interested please email us at [email protected]. We look forward to hearing from you!

Muse | Remote | iOS Engineer, Systems Engineer
Muse is an independent software company that makes an iPad app for thoughtful work. The app brings together your research, photos, and notes in a single fluid workspace: https://museapp.com
We're hiring one engineer to join our all-remote team of four. One profile that's a good fit is an experienced iOS engineer:
https://museapp.com/ios-engineer
If you're excited about Muse but haven't developed for iOS, we can teach you iOS. In particular we'd love to hear from systems engineers with experience in e.g. game engines and graphics pipelines who'd like to apply their skill set to a product like Muse:

Yep it's a bummer - this is discussed in a comment below.

I totally agree re: copy-paste. I wasn't clever enough with CSS to do this straight away but it's high on my list: https://github.com/mmcgrana/gobyexample/issues/12.
Also agree that a learn more section could be good - I'll noodle on it.

Great feedback - thanks. Georgia also works well on Mac, so I just shipped this as the default.

Yeah there is more work to do on explaining slices for sure. I'll probably create a separate example to explain underlying arrays + capacity and perhaps break out the slicing operation into its own example. Thanks for the feedback.

I'm exploring Go most actively right now. Go solves some problems that I care a lot about - systems access and process composition - for which Clojure isn't as directly designed. Clojure still has the best data/function composition I think, and I do miss that in Go.

LXC is one of several isolation layers used in the Heroku dyno manifold to ensure process security and resource guarantees. Here is a more in-depth discussion of Heroku dyno isolation: http://devcenter.heroku.com/articles/dyno-isolation.
