A great question! TigerBeetle as I understand it is a use case specific database for double entry book keeping. I.e X gives Y money and so X needs to be credited and Y needs to be debited. In this book we're not building a financial transaction system but rather an analytics system. Hope that helps!

Couple those tools with Livebook and VegaLite....and you can build some really cool things!!

@josevalim.bsky.social and the team over Dashbit have done an amazing job with the Numerical Elixir libraries. If you are not using libraries like Scholar/Explorer for your analytics needs you're missing out!

Also...making good progress on the Elixir+Finance book this morning 😉

#ElixirLang

We've all been there 🥲

It's been a long day of writing and programming, but I think everyone that picked up a copy of Programming Nerves (programmingnerves.dev) will really enjoy building the Etch A Sketch project 🎉!

@nerves-project.org + @livebook.dev = ❤️

It's Saturday morning....which means time to write! On the agenda today is programmingnerves.dev. Currently going through Chapter 3 and tidying up the traffic light simulator project after @hugobarauna.com's meticulous review 😉!

#MyElixirStatus #ElixirLang #Erlang

I'm at Joe's famous "make it beautiful" part for the Programming Nerves Etch A Sketch project 🤩. Pretty cool that you can do all this inside of @livebookdev and @NervesProject.

Pick up your copy today at www.programmingnerves.dev

Don't get me wrong, building web apps is immensely fun (especially if you are using LiveView). But building a physical circuit and interacting with it just hits differently. I've been having a blast putting together the Programming Nerves projects 😁.

#MyElixirStatus #ElixirLang

Appreciate the kind words my friend!!

🚀 Today is the day 🚀

@hugobarauna.com and I are pleased to announce that Programming Nerves is officially in Beta 🥳

Check it out at programmingnerves.dev and see all the cool projects that you will learn how to build and program with Elixir!

Wednesday is the day!! @hugobarauna.com and I are almost ready to release the Beta for Programming Nerves 🥳. Stay tuned for updates 😉.

#MyElixirStatus #ElixirLang

This mix.exs file is essentially what's on the cover page 😉:

Glad that you've been waiting for this one! This will be another self published title. @hugobarauna.com and I are working on both this title (along with my brother who is a finance professor) and Programming Nerves at the moment so keep an eye out for updates :).

😁

Stay tuned everyone! Some Elixir and Nerves goodness headed your way this coming week 😍

#MyElixirStatus #ElixirLang #Erlang

Saturday mornings are set aside for writing "Financial Analytics Using Elixir". And I must say....I'm really pleased with how the analysis framework is coming together 😍. @livebook.dev and its supporting tooling is such a nice fit for this!

#ElixirLang #MyElixirStatus

You betcha! Everyone that bought Elixir Patterns will be notified about the upcoming book release :)

We thought so too. This has been a really fun book to write and we can’t wait to get it into people’s hands :)

Elixir Patterns book & Livebooks Learn recipes and patterns specific to Elixir/OTP

We are going to go the self publishing route again like we did for www.elixirpatterns.dev. Once the book is done we’ll also publish a physical copy of the book in full color for the wiring diagrams 😉

You are very close! It’s actually a left hand versus right hand reaction time test. And you plot the result in Livebook using VegaLite:

For the ESP32 make sure you give AtomVM a try atomvm.org

Who knows....maybe everyone is using the same SVGs if you drill down deep enough lol

Game recognizes game ;)

I had to look up Tinkercard as I didn't know what it was. But the diagrams were not built using Tinkercard so I don't think I'll have any issues 🙂

@hugobarauna.com and I are hard at work preparing the Beta release of Programming Nerves. Every @livebook.dev project in the book comes with a notebook that includes the wiring diagram and code 🤩.

An eInk display with Nerves & Elixir - Getting started with Inky So I've been curious about what kinds of displays you can connect to the Pi-series single board computers for a while. I happened to accidentally order a few. Among others an eInk display. I ordere...

To be honest, I haven’t played around with any of the eink displays. But I know Lars has done some work with them on Nerves underjord.io/an-eink-disp...

Thanks for the feedback. Unfortunately my open source time is extremely limited these days and I won’t be able to implement any of the aforementioned features. But happy to work with you and merge in a PR that makes these things easier.
