Software Social Two indie SaaS foundersβ€”one just getting off the ground, and one with an established profitable businessβ€”invite you to join their weekly chats.

Software Social is back!

softwaresocial.dev

For those not familiar it is two women doing SaaS, software and stuff having very worthwhile conversations.

Good to hear you again @mjwhansen.com :)
Is Colleen on here?

I've also built a lot more utilities that are useful but tedious or even not feasible for me to build in terms of focus and attention where I essentially just hit Yes enough and I get a close-enough version of the thing.

Which changes what types of things I take on.

Did I ever share this talk when it came out? I don't recall. "Keeping Secrets in your Opponent's Hands" is about embedded hardware security. Also I think the slides turned out pretty baller

The next conference I'll be enjoying is ElixirConf EU. I'm speaking. I hope Malaga is nice in April. The cheaper tickets should still be available so get your employer to buy you some and send you to hang out with several hundred good friends and peers.

I was under the misunderstanding that Zed used Expert LSP for Elixir by default. With the RC coning out and my shit being terribly broken as it almost always has been I looked closer and found the settings.

Now my shit works again. Did tou know ctrl+click is pretty great? #elixirlang

Some text:
Firmware deltas

Firmware deltas provide smaller update payloads by only sending the differences between firmware versions.

Then an example of a firmware with a size of 10.55KB, noting a saving of 34.78MB.

Some text: Firmware deltas Firmware deltas provide smaller update payloads by only sending the differences between firmware versions. Then an example of a firmware with a size of 10.55KB, noting a saving of 34.78MB.

A firmware is never small enough.

But we're getting pretty close. We've been improving deltas to remove unnecessary resources when delivering firmware with NervesHub. Available on a NervesCloud near you.

GitHub - poeticoding/yolo_elixir: A library for object detection and seamless YOLO model integration in Elixir A library for object detection and seamless YOLO model integration in Elixir - poeticoding/yolo_elixir

So this particular setup is using YOLO through this library. github.com/poeticoding/...

It uses some Nx for pre-processing and post-processing but overall delegates to Ortex for ONNX.

I plan on using NxHailo and the AI Hat on the RPi as well later.

Yeah, yolo model.

A version of it might end up useful in the product/project. What I'm doing is experimenting on top of the real stuff in ex_nvr.

there wasn't any fancy answer, just checking my work in an orderly fashion after some sleep. But I lifted a hilarious amount of frustrated stress off of myself. I am demo:ing it tomorrow for a bit. The workshop is end of month.
