In its day (1997-2005) Groove was quite a sophisticated architecture and implementation of encrypted collaborative workspaces, using a decentralized P2P architecture augmented by optional store-and-forward relays that enabled fully offline

Some background on one of the other two golang implementations mentioned in the comments. Years ago I hired an Upwork contractor to port v1.5.3 to golang as best he could. He did a great job and it served us well, however it was far, far fr

FidoNet was a simply wonderful innovation, and it was a reflection of the creativity of its author - Tom Jennings - and his views of community and identity. https://grokipedia.com/page/tom_jennings Tom was working on F

I've been annoyed lately by posts (elsewhere) by vibe-coding startup CEOs who think they can build companies without developers. These are not serious people. Recently, my head spun around a bit when I saw an experiment done by my tea

Tangentially-related, it remains surprising that many U.S.-based developers I've spoken with fail to realize that they need to obtain an Export Control Classification (ECCN) from the US Dept of Commerce's Bureau of Industry and Se

Thx for clearing the rights and for releasing, Scott. And of course thanks to Microsoft and IBM. It would be fun at some point down the road to get some of the older code building and running again - particularly '84/'85-vint

I use my HP-16C several times every week while debugging Notecard firmware. Yes, math is integrated into IAR EWARM and there's always Hex Calc on my iPhone. But there is something comforting about grabbing this same little artifact t

Not unrelated, this is quite an amazing device - even before you consider its $9.95 price at Sparkfun. https://usefulsensors.com/person-sensor/ https://usefulsensors.com/about/

YMMV but our experience with Cat-M has been very good with regard to speed and general coverage. (Probably because it was just a tower software for LTE eNodes.) 300Kbps+ seems to be the norm.

Just so there's no confusion, you linked to the "NOTE-WBEX" which is europe-only. If you're interested in countries covered, it's best to look at "NOTE-NBGL": https://dev.blues.io/hardware

Truth in advertising: As stated in another response above, if you want to do a real computation you need to factor-in "session setup" overhead. If you config for TCP/IP (unencrypted) your session overhead is about 1kb. If y

I was using Whispernet as an example of a great user experience; that's all. There are no tricks and our prepaid/embedded pricing is real, and we will never sell anything for a loss. We're selling commercial IoT and our busi

Yep, your scenario works and it's completely possible and plausible. Messages are extremely small and efficient OTA (highly optimized and compressed). The API is JSON and messages are your own unconstrained JSON object, but they'r

I believe the greatest unrealized potential is for product manufacturers to embed cloud connectivity without the end-user needing to do anything to get it working. The Kindle Whispernet model is my ideal, where you make an up-front decision

There are no tricks to the Notecard's pricing. The 500MB/10-years of data is embedded within the hardware pricing, which is $49 for North America and $59 for 135+ countries. What's more, it's "permanent roaming&quo
