We’ll have the recording of Dagi’s meetup episode up on our channel soon. That will mark the end of season 1. We have some cool ideas for season 2.
But who do you think we should invite?

So, I'll be working on Label Studio most of February (a cool open-source tool for data labeling and model evaluation). My company is moving away from a paid service because they're tired of the rate limits, so they want an in-house solution instead. Before…

No test device? Simulate!
So basically the problem we have is this: systems we develop are for IoT devices deployed all over the world. These are expensive devices. Our only prototype is usually tied up in field trials for weeks. And the software team needs to develop, test, and debug…

Ethio Telecom Flags Risk of Reverting to Monopoly Over Safaricom Dispute - Birr Metrics
Ethio Telecom signalled that Ethiopia’s telecom liberalisation could be rolled back unless Safaricom retracts recent claims made by its M-PESA unit.

Awesome episode! Crazy to think AWS hosts 500 trillion objects, and 99.99999999999 (11 9s) of durability means they still lose an acceptable amount of data

How S3 is built
Amazon S3 is one of the largest distributed systems ever built, storing and serving data for a significant portion of the internet. Behind its simple interfaces hides an enormous amount of engineering work, careful tradeoffs, and long-term thinking.

Yeah, the article sounded really odd tbh.

This is tomorrow, planning on checking it out
Last minute cancellation of the event, sadly, but just met the association’s president. Great guy tbh. Next week will be the actual event.

almost done with the serial simulator, it uses posix PTYs to simulate our sensors. It handles commands and broadcasts telemetry continuously (all configurable). The behavior is defined in a TOML file. Added it to a test pipeline for one of the services I maintain and it works pretty well.
Used nix (not that nix) it's a crate of rust bindings for the posix api. This sim doesn't handle binary streams, but other than that it should be able to handle most scenarios. If anyone is building something that uses sensors then they're probably using some type of serial connection (RS-232 etc) and if they don't have the sensor (or it's expensive to keep it in the lab) they can just model the protocol in the toml and use this instead. I will share a sample toml but, any sensor in the world that uses serial and has a public spec can be easily modeled (i hope) you don't even need to buy it.
I'll strip out the device-specific/company-specific stuff and make it generic, then share the repo on GitHub.

Oh, and added "replaying". You can basically take sensor output from a device that's in prod and replay it in your dev environment to reproduce certain issues and handle edge cases.
