Comment: Re:And Northrop is right to do it. (Score 2) 132

I suspect auditors is behind a process I noted at a large American company I worked at for a bit:

In the engineering office, the engineers were using laptops. The laptops were managed by a third party, which bought new parts from a fourth party through a fifith party.

If one engineering laptop broke, it could take 2-3 weeks to get it repaired.

In the meantime the engineer can't work, and just costs money. This happened, in my office, to a consultant - costing about a laptop a day.

But in some budget somewhere I'm sure it looked cheaper than having a hired IT-guy in the office with a pile of spare laptops.

As far as I know network synchronization has been solved in many different ways already, and is not a problem. Can you give some example on where it hasn't been solved?

Z-wave, Zigbee, 802.11*, BLE have all solved that. If you invent more (mesh) networks you'll have to solve it for your stack. But it's not like solutions doesn't exist. Or that these protocols have anything to do with IoT. (Timing on networks like ethernet or CAN or radio protocols like GPS or 4g/LTE have all been solved as well, and have even less to do with IoT.)

I'm not saying it's easy, I'm just saying that these problems are solved and there's no "endangered by inaccuracy" here.

and no,

“For example,” he writes “for a driverless car to decide whether what it senses ahead is a plastic bag blowing in the wind or a child running, its decision-making program needs to execute within a tight deadline. Yet modern computer programs only have probabilities on execution times, rather than the strong certainties that safety-critical systems require,”

has nothing to do with IoT _nor_ timekeeping.

I couldn't figure out, I can't figure out what they are talking about.

I've only seen IoT things that either don't care, at all, about time: all the datakeeping is local, and you can ask them or not ask them about the state and the logs (a fridge or a kettle doesn't care what your clock is),

or IoT things that are real time. that doesn't care what your clock is because they will just want to contact you as fast as possible, like a fire alarm. It really doesn't care what your clock is, it just wants to get the message through as fast as possible - which is a problem, but not this problem.

Locally IoT things are usually also real-time, and then they only care about highest possible bus delays. Like a car. A car doesn't try to talk to itself like it was several IoT devices. A thermostat reads temperature and adjust the power output accordingly in a timely fashion, knowing that the delay between the reading of the temperature and the switching of the relay isn't too delayed (seconds or minutes is also real-time), if the sensor-relay delay is too long it goes into limp-home mode and probably turns off the relay to be safe.

I tried to think of cryptological solutions that required to systems on either side to keep an accurate time, but I couldn't. I know some keycode boxes use time as a factor when they generate the login key, but they really don't keep accurate time and that doesn't seem to be a problem...?

Anyone that come up with a good example?

Obviously there might be more that would run the games under Linux or SteamOS.

I personally have one full desktop machine running Windows _only_ for games. If I could run SteamOS instead, or Linux, I would.

But thanks to Steam in-home streaming, I now have more computers running Linux because I can stream from the heavy desktop. Like the NUC running Mint (Kodi, Firefox, Steam) in the bedroom.

I think the point is that google once said: Come to us, you can play in our sandbox, use our stuff, create your account with us, you can do whatever you want... ...now they close down those services, one by one.

Granted, this time, this event was rather minuscule.

The question is: Why do they keep shutting down things?
