In its day (1997-2005) Groove was quite a sophisticated architecture and implementation of encrypted collaborative workspaces, using a decentralized P2P architecture augmented by o…

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…

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/…

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 spu…

I began recruiting for what became Azure in Jan 2006. I was chief software architect / cto at the company. Amitabh Srivastava and the legendary Dave Cutler were the leads, with Dav…

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 t…

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 …

At Software Arts I wrote or worked on the IL interpreter for the TRS 80 Model III, the DEC Rainbow, the Vector Graphic, the beginnings of the Apple Lisa port, as well as the IBM PC…

Beyond being 60-bits, programming the 6400/6500/6600/6700 was interesting and memorable in other ways. - Ones' complement (rather than two's complement) binary representation of in…

"Now, no one bats an eye if you ship the most secure crypto you want." The most surprising thing to me is that, in speaking in the past several years with younger entrepreneurs, th…

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 …

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/

Tangentially related: if you're fascinated about how all of this vintage equipment used to work, and if you find yourself near downtown Seattle on a sunday with an hour or two to s…

LTE feels as though it is going to be an exception to that rule. This is the dawn of eMTC lifecycle

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 b…

30mm x 35mm, plugging into a standard M.2 Key E socket

All of USB, I2C, low power UART (9600 fixed), and high speed USART. They all equivalently are JSON request/response ports. I2c uses a simple serial-over-I2C protocol. Most customer…

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/…

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 (unencrypte…

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 los…

Happy to comment. We've been working on this for several years now and we're super proud of what we see people building and deploying. The question is a bit general, so let me just…

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 …

Honestly, our thanks to Google's WebSerial folks who helped us to deliver the experience. It's quite wonderful. http://dev.blues.io
