Not sure if it's related, but the United website was down this morning for a while as well.

Spoke to folks at another airline a couple of years back. Flight registration, SABRE, and aircraft maintenance were all managed through the same systems. I found that both surprising and unacceptably risky.

Roughly OT: I have yet to have seen anything that makes me look forward to the IoT, and when I talk to the voices of vendors in my head I'm basically telling them "Stay out of my refrigerator, my furnace, my toilet and my smart doorlock that I'll never have." I just don't feel that anything relevant to the IoT is missing from my life. At all.

My guess is that for each person some small thing will make sense, which is sufficient to drive the costs down and the technology forward. For example, good sleep is really important to me. So I used the Philips Hue bulbs and a NUC to build a smart home lighting system that behaves much more like daylight. When I describe it to people, quite a number really want it. Not bad enough to get my code off GitHub and instal…

Neat. Did you try to coordinate room lighting color changes with computer screen colors controlled by fl.ux?

I was flying from Dublin to Newark on Saturday on a United flight. At some point during our flight the entertainment system needed to be rebooted. When it came back up, the splash screen hit me with a huge amount of nostalgia. It was RedBoot with a kernel build date from 2004. Obviously this is the entertainment system and not something more critical, but it's telling. There is a huge cadence mismatch between softwar…

There is a huge cadence mismatch between software cycles and capital good replacement cycles. How well would you say that Tesla is coping with this as a company? For that matter, what about Apple? I can't even imagine the number of security patches that have gone into the Linux kernel in the last 11 years. Let's take a step back and think about this statement. Isn't this insane? We know enough to be able to build som…

I honestly think most companies don't care about longevity anymore? I look at all the appliances in my home, and just plan on throwing them out when they break down. I remember years ago, a car manufacturer did a study on what consumers care about when buying a vechicle. It wasn't engine size, or the stuff they were advertising; it was cup holders. I don't think we have evolved that much? (vechicles were forced to last longer because it was such a huge expenditure, and even the most thoughtless buyer was forced to look for longevity.) I literally think durable good manufacturers(with the exception of most automobile companies) design products to fail within three years? I can hear the CEO now, "Get the name in their head, and we have them for life--my life as a CEO?". Worst case senerio, the product becomes a joke like Fiat did in the 70's; the CEO is long gone, but on his rein, the books looked good?

The appliances in my house were bought because of all the bells and whistles. I didn't buy them, but am forced to work on them when a sensor fails. They have gotten so complicated, parts so expensive, service manuals hard to get; I just throw them away when they fail. I don't like it.

I think, if consumers start demanding it, we will go back to buying a based on longevity, and not on the newest feature? Every time my dryer's alarm goes off, I am reminded it's a durable good. It's almost reminding me to save up?

This is the Achilles heel of the entire Internet of Things and smart appliance trend, and I think this will bite everyone bad. After 50+% of these vendors go out of business in the next decade, their products won't get updated, and people will wonder why their "smart" TV can't watch movies from whatever replaced Netflix/new whizbang video service. They won't be as likely to buy any "smart" thing again.

I bought an LG smart TV a while ago. It stopped receiving firmware updates after a couple years and is now way behind current models in terms of features--and, I can only imagine, security patches. I will go out of my way to buy a dumb TV next time.

> I will go out of my way to buy a dumb TV next time.

How? I don't see any dumb TVs for sale.

Flux can actually do that directly! https://justgetflux.com/news/pages/bigupdate/

It doesn't really matter that much if it's dumb or smart. You can use a Chromecast with either, and refusing to buy one kind limits your choices.

You can use a Chromecast with either, but one of them can also spy on you without your consent.

Not if it isn't connected to your network.

Is this what an actual cyberattack / cyberwar looks like? Imagine how much money is being lost right now as a result of this disruption. Somewhere hackers are popping champagne.

UAL stock took a $1 nosedive (hah) at 10am.

Find out who made money by shorting it, there's your list of suspects, or at least co-conspirators (if this turns out to be a hack).

The IFE system on a 747 I was on a couple of years ago was running Windows 98, complete with graphical boot screen :-) (Edit: Removed airline, I like them too much.)

> so I'm guessing you refer to some sort of fibre-based device that actually impedes light to go in the other direction, and thus the security is via physical means? Correct. To simplify, imagine a diode on one side and a photodetector cell on the other. On a microcontroller, this would be an opto-isolator ( http://en.wikipedia.org/wiki/Opto-isolator ). Of course, the higher levels of the OSI protocol you're using ne…

It's really not all that complicated. You get a couple of these Ethernet to 100FX converters: http://antaira.com/products/media-converters/unmanaged-conve... Then you hook them up with just one fibre strand (instead of the usual 2). You obviously can't use TCP over that since that requires a 2-way connection, but UDP works just fine. You'll probably want to wrap your data in some error correcting code, too.

I've found that using hashes and sending duplicates of the data seems to weed out any transmission issues in a one way system.

How well would you say that Tesla is coping with this as a company? For that matter, what about Apple? Apple just kind of assumes that you have the latest shiny, because why wouldn't you? This induces a phenomenon I call the Apple Turnover: when a software update aimed at new Apple things comes out and makes your old Apple thing not run so good anymore. Sluggish iPhones are the hallmark example today, but I was bitte…

I think this is a strategy by Apple, and will eventually backfire. But then again what do I know about consumer preferences, I am typing this on a Toshiba Satellite PS25-607--that is literally held together with tape, and opened so many times I can visualize the screw holes?
