It never really gained any traction outside corporate. There is a winner-take-all mentality in microcontroller RTOS... why use Mbed if Zephyr supports 10x as much "stuff" out of the box? Also, given the primary source of funding, it really only practically functioned on ARM processors. Pragmatically it seems multiplatform RTOS are the only ones that survive long-term, single platform seems always doomed, a bit different than the desktop/laptop/phone market.There was something of a product-tying thing going on with Pelion IoT cloud platform, which used to be free, but the free tier disappeared. It was pretty awesome for hobbyist use until they intentionally got rid of the hobbyists, presumably to "save money". However this seems to be a common pattern for decades, the devs who influence million dollar contracts during the day want to play with pirated/free versions at home at night, so arguably Pelion and thus Mbed shot themselves in their own foot.I wonder how much C19 killed Mbed a couple years later. After STM32 procs and ARM microcontrollers were unobtainable for couple of years, there was no way to get hardware to run Mbed.It was a bit memory-hungry; IIRC by the time you got a full IoT platform with auto-updates and telemetry over WiFi working on commodity dev board hardware, you were out of either flash, ram, or both so you couldn't run your app.I have happy memories of being introduced to LwM2M protocol; it was an interesting innovation on MQTT but a little too "organized" for widespread use. Take MQTT and "compress" by turning all common (and uncommon) nouns and verbs into integers; kind of like the old Apollo spacecraft computer, kind of like a fixed compression standard.A final interesting discussion point is tool manufacturers going out of business is a pretty strong signal the bubble is over. The permanent solution to "The S in IoT stands for security" may very well be the IoT industry drying up and blowing away, and this shutdown is a sign of the start of the end.Anyone else have fond memories of MbedOS? I thought it was pretty awesome back in the day, although I switched to Zephyr years ago. Other contemporary microcontroller or IoT comments?Original SubmissionRead more of this story at SoylentNews.

But on the other side of the Atlantic, somebody has pipped him to it.That somebody is a real tech wunderkind, a 36-year old Bosnian/Croatian by the name of Mate Rimac.During his high-school years, Mr. Rimac won local, national and international competitions for electronics and innovation. Then he got interested into racing, and, at the age of 18, bought the cheapest racing car he could find, a 1984 BMW E30 323i. After that car's gasoline engine exploded during a race, he decided to turn the car into an electric one.That was 2006. He was laughed at and ridiculed for the idea alone, but by 2009 his car started winning races, while beating a couple of world FIA and Guinness records. That success encouraged him to try and start a company which built electrical cars, insisting that the company should be based in Croatia, which did not have a car industry to talk about. Fast forward some more episodes of ridicule, tethering on the edge of bankruptcy and so on, and that fledgling company has turned into the main provider for battery software and electrical powertrain systems to about half the car industry, world-wide: Porsche, Hyundai, Kia, Renault, Jaguar, Aston Martin, SEAT, Koenigsegg and Automobili Pininfarina are some of its customers.Rimac didn't stop building cars though: supercar enthusiasts know him, and his partner in crime, designer Adriano Mudri, as the men behind the Rimac Nevera (which can be yours for a cool (estimated) $2.2 million), and the guys who, three years ago, took over Bugatti from Volkswagen, with the participation of Porsche.And now Rimac Automobili has come out with the Rimac Verne (yes, yes, that Verne), a fully autonomous robotaxi. Rollout towards world domination starts in 2026 in Zagreb, Croatia, where you'll be able to order its taxis through an app, complete with the interior lighting and scent you want. What you will need, though, is a bit of trust: there will be no steering wheel or brakes present, which might turn into an advantage in case you want to get rid of your elderly mother-in-law for a while.Read more of this story at SoylentNews.
