Yeah, they're writing technical reports on shit that someone has packed into a chute. Oh, how easy it is for experts in field A to assume they have been born with knowledge from field B. Namely, those meteor experts who just don't get what every skydiver learns after a while: shit sometimes get packed into the chute. This whole thing is just so full of fail I don't know whether to laugh or cry.

it fails to address how the rock got to the speed of several hundred km per hour by the time it flew past him

You can address it yourself. Gravitational acceleration is 9m/s^2. 300 km/h is 83m/s. The rock could have easily been going less than that, say 50m/s. It takes 6 seconds for it to accelerate to that speed from rest. It didn't start at rest.

He was professional long enough. It didn't work. Kay doesn't seem to care enough if you're nice to him. As a leader, you have to use what works. Demonstrably, being nice to Kay was leading to nowhere. Granted, being not nice to Kay may not work either, but it's definitely worth trying. It's also worth it to let everyone else know that this kind of shit attitude (like Kay's) is not going to be taken lightly.

Yea, but if you mess up and do something he declares "STUPID", it's off to the public stocks for you in a flurry of expletives. IMHO Stuff like that just lacks class and reflects badly on him.

On the contrary, I think this doesn't reflect badly on him. Kay has been pushing it for ages, and there was nothing else to be done. It's in everyone's best interest that the public is warned a) not to try such tricks, b) to stay away from Kay until he improves his behavior. Remember, Linux kernel is developed in the open. Public scorn is to be expected. You don't like it, maintain your own fork, that's what git is for, you know.

Sometimes there is in fact a need for public shaming, I think. Kay asked for it, Kay got it delivered. It's as simple as that. Doing it in private would be a disservice to everyone. It's a developer community, there's no point for keeping this sort of thing private. It goes against the very grain of things, I think.

Of course these days all of this can be done, too, much faster, on off-the-shelf hardware. Just because the hardware doesn't have tag bits doesn't mean your compilers can't implement them. I'm running a bit of safety critical code on a bunch of ARM CPUs and all of the data RAM contents are tagged, pointers are tagged, and there is also software-driven error correction for RAM, execution log, restarts, those sorts of things that were en vogue at one point or another in the "hi-rel mainframe" market.

I have a couple of off-the-shelf servers from Dell that not only have error correcting RAM, but also have a spare memory stick and can cope with the failure of an entire chip on a RAM stick. So what you hail so eagerly is - who'd have thought - a standard feature on off-the-shelf hardware that can be had under $2K.

You're on to something here, but not for the reasons that you think. NASA has been releasing source for a long time. It's only that getting this source requires at least a mountainload of paperwork (U.S. citizens only, etc.), and it's usually costly. It's not like they don't have a catalog already. If it's going to be more of the same, then I'd call it outright deception. Note that nowhere it's stated that the code will be under a free source license!

How about you drive 65 miles an hour around a curve in traffic and have someone else tuun off the ignition? whats that? you won't do it?

Had that happen, had a service brake failure (pinhole in the flex line), and had an ABS failure in very slippery conditions. I'm here to tell the tale, and nobody was hurt, and no paint was scraped. Pretraining is key, and anyone who has a car and hasn't figured out for themselves how to handle such situations is playing with human life for no good reason. You're supposed to actually try things out. It's easy, if you're not an oaf it's safe, so what's the deal?

in automatics because in drive the wheels can't turn the engine, so the engine comes to a complete standstill

Stop making shit up. It doesn't work that way at highway speeds, and at least in my car, the automatic transmission stays engaged if I turn off the engine, all the way down to 30mph or so.

Yeah, sure, ha ha. Airbags often deploy so fast that by the time they are deployed, you are usually nowhere near the airbag. Even in fairly high-speed crashes you often impact an already deflating airbag. Never mind that modern cars have multi-stage airbags that inflate sufficiently for the severity of the crash.

Oh, and never mind that modern cars have many airbags that are nowhere near your front. I've personally checked out a side curtain, and it was quite nice. The T-bone felt like being pushed onto a bed by a rowdy kid jumping on you :) I didn't even get a headache.

If part number changes, how will the customer know there is now a new part?

Every online part retailer worth their salt has some indirect access to car vendor's part database that, surprise surprise, includes part substitutions. Had you ordered any car parts online, especially ones that fail due to bad design and get redesigns/upgrades, you'd have seen it. This ignition switch part is rather unusual in this respect - a redesign was done without retiring the old P/N and having a "new and improved" P/N as a designated replacement.

On some cars, I've seen parts go through 2 or 3 rounds of such upgrade cycles. When I eventually pulled the failed part off the car and went to buy a replacement, there was a substitute part #1. That substitute was substituted with #2. Eventually, that one had substitute #3, which was orderable.
