  • Unable to attend

2020-03-06

Justin Schneck

  • Elixir 1.10 has ability to apply config via releases.exs without reboot, but really bad idea to promote
  • Dropping support for OTP < 21, Elixir < 1.7
  • NIF on_load failures can make even Shoehorn get into a crash loop

Greg Mefford

  • Nothing meaningful to report

Jon Carstens

  • Working on nerves_pack - removing wizard and GPIO to not have to deal with optional deps
  • Shoehorn MFA isn't supervised in the same way, was intended to easily fire off a task
  • Justin has a proposal for a different strategy for the future of Shoehorn - needs feedback/iteration
  • Found some mDNS issues when querying from one Nerves device to another, e.g. EPMD

Connor Rigby

  • Erlang distribution is great for development but not a good default for production
  • Good to have it in nerves_pack as an option

  • started work on a long-term pluggable firmware loader
  • progressing EEF proposals

Jon Carstens

  • VintageNet releases
  • VintageNetWizard releases
  • NervesPack releases

2020-01-10

  • Starting to focus on LTE stuff for upcoming requirements
  • Researching TPM support on x86 platforms - promising progress on the Linux side of things with TPM stack
  • IBM has a TPM simulator, which is really helpful to avoid burning real hardware
  • New nerves_bootstrap that supports nerves_pack
  • Looking at README vs. Gitbook for guide-based documentation
  • Working on logo / website design updates for Nerves
  • Starting NervesConf 2020 planning - one day, short talks and training workshops interspersed, happy hour with show and tell (rather than lightning talks)
  • Planning to be conjoined with Gig City Elixir conference

Frank Hunleth

  • Working on EEF embedded WG website with showcase, use-cases, and links to Grisp, Nerves, Yocto, etc.
  • Two other proposals in embedded WG:
    • Binary packages in Hex, similar to Pypy
    • Reduce BEAM boot time, maybe by loading all the BEAM files in memory, snapshot to disk cache for faster boot next time
  • nerves_examples - started pushing stats from CI, totally changed opinions on what should be in there. Now feeling like it would be great to include whatever people want like Scenic and LiveView, Kiosk for example.
  • Worth the maintenance burden based on the stats we can collect and having working starter projects.
  • nerves_init_ramfs - originally intended to support encrypted rootfs, but also support generic auto-failback across rpi and x86
  • Connor is working on nerves_time support for realtime clocks

Greg Mefford

  • Not much of anything lately - focusing on upcoming talks about OpenTelemetry

Jon Carstens

  • Nerves Hub Device - Justin's main concern was really on the naming of the package, but pretty much fine integrating the code.

  • Testing Beaglebone PRU stuff

Frank Hunleth

  • Pushed the Beaglebone PRU stuff
  • fwup 1.2 released and on homebrew
  • Mostly time spent recently on project management on nerves-hub

  • Working to get serial number support in for systems so that node and network names can take advantage of it. Solves the problem of many nerves devices on a network all trying to use nerves.local
  • Want to get linux 4.14 in a system update soon, will probably take a couple of weeks to shake things out and make sure we have all the right configuration.
  • BBB system needs a change to fix device tree overlays

Connor Rigby

  • Working hard with Frank to come up with a good API for interacting with network layer
  • Interacting regularly with people on the elixirforum.com Nerves section. Great job!

Tim Mecklem

  • Testing the firmware.push PR on Windows and Mac, focusing on that in the short term
  • Multi SSID still in flight but secondary on priority
  • Focusing on responding to new posts on elixirforum.com to make it a responsive environment so people feel they can trust it as an outlet for support

Areas of support

There are a couple of areas where some help would move things forward and alleviate Frank and Justin's backlog

  • Linux kernel 4.14 updates for Raspberry Pi and BBB systems
  • Parser for network status updates - see Frank for details

2018-05-18

Tim Mecklem

  • Working on a branch for multiple WiFi SSID support and Windows support
  • Working on a thing internally for RingLogger messages over Phoenix Channels, might be able to contribute some/all of it as OSS

Greg Mefford

  • Working on training and a talk for Code BEAM STO.
  • Looking at nerves_networking, nerves_wpa_supplicant

Connor Rigby

  • Thinking about Windows support as a side effect of wanting USB mass storage support
  • Building a configfs project separate from nerves_runtime, involving lots of shelling out, so trying to make that better.
  • Working on nerves_networking and nerves_wpa_supplicant

Paulo Gonzalez

  • Recently wrote a stellar blog post 🌟
  • Excited to join the community and help out
  • Interested in keeping the Slack community going the way it is, and also ramp up the participation on Elixir Forum

Justin Schneck

  • Working with SmartRent on the firmware update server to support device connections to the server using websockets and client certificates.

Team discussion about how to handle the Elixir forum

  • The Slack community is really great for real-time support
  • The forum already exists and people are going to post Nerves-related things there under the tag whether or not we have a dedicated sub-site
  • It could be another great avenue for posting small updates and push people to our documentation
  • A forum is a great place to contribute asynchronously if that's how your personal schedule allows
  • We can link from Slack to a forum answer, but we should optimize for solving the documentation problem that caused them to have a question
  • We should use these as indicators to improve the documentation
  • Funnel questions/problems from Slack to Forum to Docs organically and/or intentionally
  • Paulo has volunteered specifically to keep us honest and start to seed content from Slack to Forum
  • It would be good to get in the habit of posting about new releases of all the Nerves organization projects, potentially with some automation based on change logs, so people have better visibility into the many things we're working on.
  • Decision is to work with the Elixir Forum to get the Nerves sub-site set up and commit to being as active there as we can be.

2018-03-09

Justin Schneck

  • Working on lots of little features that are helpful for commercial environments:
    • Artifact sites can pass headers and query params (e.g. for authorization headers)

    • People can get in touch if they want to get involved

Greg Mefford

  • People enjoyed LoneStar Nerves training
  • ElixirConf US training CFP just opened, so let's talk about strategy for that

2018-02-09

Frank Hunleth

  • Working on circular logger with Justin, it's much better than the console backend
  • Going to be publishing a small shim (called shimmy) for containing ports or daemons to properly close them if the BEAM shuts them down
  • SmartRent has started working on the firmware management server (intended to be open-source, but not yet)

Chris Coté

  • Still pushing through the kitting system, still pretty specific to our product (with Arduino firmwares, etc.)
  • Busy getting it out the door now, so will have to make it more general-purpose
  • Planning to push Nerves at CODEBEAM SF: lots of IoT but not Nerves.

Greg Mefford

  • Prepping for LoneStar ElixirConf training
  • Working on several Picam PRs

Justin Schneck

  • Justin is working on host tools infrastructure to support things like rust and pru compilers (probably the last "major" feature before 1.0)
  • Beefed up the tests to cover the host tools.

2018-01-26

Frank Hunleth

  • Presentation tomorrow, so not a lot of Nerves work, just helping with the things Justin's working on.

Justin Schneck

  • Working on changes to the Nerves compiler infrastructure and a Nerves 0.9.0 release.
  • Seeing the light at the end of the tunnel on a Nerves 1.0.0-rc1 release.
  • We've moved the network operations to mix deps.get so it doesn't download artifacts during mix compile time.
  • There's some community effort around supporting BeagleBone PRU compiler using the Nerves Platform behavior, which is neat that we were able to support that kind of extension. Frank has concerns that we can discuss separately.

Tim Mecklem

  • Went down the rabbit hole of Windows USB gadget support. Currently kind of stuck on some sysfs stuff.
  • More interest in Nerves generated at Code Mash. Hosted an open-space to walk people through getting started in 20 minutes.
  • LoneStar ElixirConf keynote coming up. Also, stickers for the Nerves training!

Chris Coté

  • Consulting on a Nerves-based product
  • Working on a "kitting system" to sync up unique firmwares, compiling Arduino firmware, flashing SD cards with certificates and encryption keys, device registration back-end, etc. https://github.com/rosetta-home/kitting_system
  • Working on a mqtt-based system to syncing data to a cloud server (metrics, pictures, etc.)
  • Talk accepted at Code BEAM SF (March 14-15), talking about Firmata library.

Greg Mefford

  • LoneStar Training prep
  • syslog and kmsg log collection RFC/PR
  • zbar library for barcode-scanning from a JPEG image

Connor Rigby

  • Added conditional features to the Nerves linter
  • Working on a Nerves-based joystick library
  • Working on a wrapper around conman to try to deal with some network issues, especially with hostapd
  • Started working on a PowerPC compiler, but unlikely to do much more with it

2018-01-12

Frank Hunleth & Justin Schneck

  • Working to put out new system and toolchain releases primarily for:
    • Easier support for reverting back to old images (not as big a deal as expected)
    • Fix the bug where if you download the artifacts and they stop mid-way, to try again instead of getting stuck
    • Running into issues with changing functionality in the nerves_bootstrap archive, and trying to decide the best path forward

Connor Rigby

  • Wrote some blog posts and answered a lot of questions in Slack ❤️

Greg Mefford

  • Nearly ready to release a new version of nerves_neopixel, which is backwards-incompatible but has support for a lot of new features for drawing on a matrix using a C port with a simple ASCII interface.

Amos King

  • Working on IPv6 support for Nerves at work
  • Thinking a lot about testing in hardware

2017-12-15

Frank Hunleth

  • Working on hardware-in-the-loop test infrastructure this week
  • Mostly working now, planning to wrap up the docs and publish a blog post
  • Hardware testing and ability to revert failed firmware

Justin Schneck

  • Hardware test uses Bootloader to detect test firmware failures and revert without bricking the device
  • On every commit to a system, it will post back the test results to the GitHub commit
  • Need to clean some things up still with how the new firmwares get downloaded and tested
  • Working on getting WebEngine things working for Kiosk systems
  • Have a way for a system to have a preferred platform to build under because WebEngine has some path-length issues.

Greg Mefford

  • Focused on training materials for Lone Star
  • Fixing some rough edges based on going through some training exercises (e.g. the Nerves System Shell docs)
  • Thinking about making Docker the standard for Nerves System Shell both Linux and non-Linux hosts

Jeff Smith

  • Mostly real work stuff on Le Tote's Kiosk system
  • Working with erlexec, which is really nice for Port management
  • Thinking about how to use it as a generic way to use this as a daemon-management system from within Nerves
  • Working on some picam features (e.g. motion vectors)
