Project updates
Editor's note: I had not seen property_table before and you might not have either. From the README:
In-memory key-value store with subscriptions
PropertyTable makes it easy to set up a key-value store where users can subscribe to changes based on patterns. PropertyTable refers to keys as properties. Properties have values and are timestamped as to when they received that value. Subscriptions make this library feel similar to Publish-Subscribe.
On to the updates:
- Fix unintended exceptions being raised when the filesystem updates start failing when table persistence is enabled
- Reduce time when an unexpected VM exit could result in a corrupt persisted file. The backup would be usable, but now the critical steps only involve renaming or deleting files.
- Include upstream Erlang aarch64 div/rem JIT patch to fix a math error on aarch64 devices that affects the atecc508a library. This library is used to authenticate connections to NervesHub and other cloud services. See https://github.com/erlang/otp/pull/7567 for details.
- Remove acknowledgement when a clean build might be needed when called from non-interactive terminals
Community updates
Nerves Meetup for September
A Nerves Meetup with the early name OTP 26 is posted and will happen on the 27th/28th of September. Check the event page for the real info.
ElixirConf US, September 5-8
(this was in the last one as well, keeping it in for practical information)
ElixirConf US is happening soon! No NervesConf before it this year unfortunately.
I (Lars) will not be going as Florida is a deal-breaker for me. I hope subsequent conferences happen in a state where I can safely bring employees and friends. I would love to meet the US side of the community in person but not this time.
Jason Axelson seems to be the only one flying the Nerves flag at this particular conference and he is taking my old Inky library and running with it. The updated Impression devices, Scenic, lots of fun I'm sure.
Plenty of other interesting talks as well of course.
Code BEAM Europe, Berlin, 17-20 October
(this was in the last one as well, keeping it in for practical information)
This conference is quite close for me and I can just go by train so the plan is to bring the full compliment of me and my team. The line-up is looking bad-ass!
On the Nerves-front we have the best-titled talk by Quinn Wilton. The Tamagotchi in my Hands: Anarcho-transhumanist Biohacking with Nerves. I expect she will blow us away. Abstract says Clippy is involved.
Sanne Kalkman is talking about tracking cats with the GRiSP board. Not sure if that's Nerves or mostly embedded Erlang.
Cocoa Xu will cover her work with TensorFlow Lite (tflite) which is very embedded-oriented. The embedded-friendly option for running ML inference using Nx and if you want to use Coral TPUs and such. Read more here.
The ladies bringing the embedded this time around.
I am going to be putting on what I think is the first live iteration of a BEAM Radio with me and a couple of the speakers.
Beyond that we have José Valim, Saša Jurić, Hayleigh Thompson, Ingela Andin, Sigu Magwa and many more.
Participating in the community
The Nerves community is found wherever Elixirists gather. Try any of the following:
- Elixir Slack, #nerves channel
- Elixir Discord
- Mastodon/Fediverse at genserver.social
- Elixir Forum Chat
Supporting the Nerves project
We want to encourage everyone to contribute in whatever way works for them. Here are some ways we currently recommend:
- Write or port a new hardware library and include it in the Elixir Circuits collection.
- Give money to the project via Open Collective.
- Get in touch about taking over maintenance duties for some libraries, we might be able to provide you hardware.
- Apply for an EEF stipend on something Nerves-related and build it. We can help if you have questions about this.
- Send corrections or improvements for documentation wherever it fails to help you.
- Write about Nerves, give talks about Nerves. Make videos about Nerves. It is all good.
Finally, if you have questions about the newsletter or want to suggest something you can simply respond to this email it will go directly to me, Lars, who edits this thing. Let me know what you think.
