I'd like to know what fantasy universe we're role playing if you think that people don't still grow up with drunk driving.

My advice is to go for a 5 mile walk along streets with traffic between the hours midnight and 2am on a Friday night/Saturday morning. I'd say to bicycle it, but I'm not trying to get you killed, just scare some sense into you.

Asserting I don't know things is an argument you lost as soon as you made it. You don't know what I do or don't know.

Presume I do know about proprietary codes. Could my statements still be true? Yes. Indeed. As a programmer who has works with these codes, I know it is complete hogwash to just wave your hands like that. Could a malicious person screw up your car through the OBD port? Yes. Can they screw with the safety systems? No. I'm sure there are ways they could cause you lots of problems, but your brakes and airbags will still be working.

You don't seem to realize that the brake and airbag computers are physically separate devices. It doesn't help your position to just presume that the proprietary codes can alter those systems. If you were more familiar with the technology, you'd understand that all the active diagnostics are in the Engine Control Module and Powertrain Control Module, which are probably the same physical device, and that device can't actuate the brake or airbag systems; all that plugs into it is the sensors to tell it when the ABS or traction control engages, and a flag that says the airbag state.

And no, traction control does NOT involve powering the wheels. If you're in gear, the engine has to change speed for a different amount of power to get delivered to the wheels. There is nothing in the wheel that has any sort of gearing that would allow for the traction computer to change the wheel power delivery separately from the engine, and the engine responds much more slowly than the traction system. And the traction computer is still running with the ECM unplugged. I could go to the top of a hill, unplug the ECM, and as long as the battery is connected I could roll down the hill and slam on the brakes, and the ABS would work perfectly. The same computer does the parking anti-roll.

The idea that the ECM could actually turn off the brake power is funny. For bonus points, find a repair manual for your vehicle, discover where in the engine the power brake boost is sourced, and then ask yourself if it makes sense that it could be disabled while the vehicle is in gear and moving. I'll give you a hint:
It uses engine vacuum. Power brakes have mechanical assist. If the engine is in gear and the vehicle is moving, there will be power brakes, even with the battery disconnected. If you have an electronic brake-assist computer, you can lose that if the battery is disconnected, but the ECM can't disconnect the battery. But even if it could take that extreme step, you'd still have power brakes anytime you're in gear and moving.

I did not say anything about firewalls, so I'll assume the whole passage accusing me of believing in magic ones was just a fantasy interlude, except to reiterate that the brakes and airbags are NOT controlled by the ECM computer that is the one that shuts down a couple minutes after you turn off the car.

get a clue.

The one thing we agree on.

You claim a bunch of specific facts that if true, would support your arguments. However, they're false. All the ECM gets from the brakes and airbags are sensor readings. There are no actuators connected between the safety systems and the engine computer.

I do apologize for the typo where I wrote ODB instead of OBD.

MOOC is not a commonly used term. The ones you mentioned are. Do you understand the difference?

Do you understand the difference between publishing a summary on CNN and publishing on a site where MOOC should be as commonly known as a term like SSD? If you are even remotely part of the IT industry, it is very unlikely that MOOC is a term you are unfamiliar with.

In terms of common usage, I would put MOOC in the same category as a term like UAT. Unfortunately google disagrees with me, since it appears MOOC is twice as commonly used as UAT (another term no one here should be hearing for the first time).

Fuck off with your prescriptions as to what acronyms every person "even remotely part of the IT industry" should know.
I only know MOOC because it's a shitty buzzword. I didn't know what UAT was because there are dozens of possible meanings, and the likely meaning you're referring to is related to "UX" bullshit where you talk about the user's feelings as they use a program blind.

Even if one has heard the acronym before and has an inkling of what it means, it can be handy to have the acronym fully stated from time to both confirm that it's still an abbreviation for the same topic and not an alternate use of the letters, and to help remind the audience of some of the particulars that might be glossed-over.

...I don't see it wrong to consider the duration of the research effort plus the historical record it leaves (ie, so future generations have a harder time making contrary claims in hindsight) s not being valid criteria for a lifetime body of work. Indeed, after the period of speculative hysteria in the news is over, immediate documentation is the best way to ensure that the legacy and history is realistically preserved. The era of photography began to help this (though is subject to manipulation) but getting the narrative of the participants recorded before they have an opportunity to retroactively change their opinions too much is helpful in honestly understanding what happened.

I dunno why you want to beat it into the ground that you have poor taste and dislike books popular with nerds. You haven't been able to articulate any sort of reason to even be communicating an opinion. You give a conclusion, but don't support it at all. Just pure negative assertion, with no attempt to add value. You really are just trying to be "hip" by hating literature! ROFLCOPTER

And I really, really doubt you read all of Rand's works. People who dislike an author, who are not professional editors, only read a small number of books by that author. Whining about the supposed low quality of an author's entire body of work would require reading not only good books, but books you think are awful. You'd be reading an incredible amount of crap. And there are so many more books than there is time that a reader could read them! I don't think you really considered what it says about your taste that you claim to be expert in the entire bodies of work of multiple authors who have no worthy books at all.

You must be the biggest Rand fan in the world if you actually sat through all of those. We The Living was a masterpiece, which is probably why nobody talks about it; it doesn't fit into American political conflicts. But she wrote some real stinkers too. There is no way that a non-fan read it all.

Now to throw down the gauntlet: name two authors that you do read, and the best example from each of their bodies of work. Show us what a more distinguished reader, who rejects pap like Kim Stanley Robinson, turns to.

Comment Re:This is basic planetary physics.. (Score 1) 102

The way I understand it the lost of the magnetosphere allows the solar wind to push the ozone back to the nightside and some off into space, this thins ozone lets the UV disassociate more water vapor (that's lighter than air) into hydrogen and oxygen, the hydrogen is lost to space because it's so light and the oxygen that doesn't get blown off into space oxidises any methane or carbon monoxide in the atmosphere on the way back down to the surface. This causes the atmospheric pressure to decrease, which cause the water to boil at a lower temperature, putting more water vapor into the air to be dissociated and lost, in an accelerating death spiral.

Thank you.

IPMI interfaces with hardware and knows nothing of the OS. If you're using IPMI to mess with your OS, then your vendor has implemented hooks into your specific OS in their specific BMC/iLO/iDRAC/whatever controller, which you can access via their tools, a web portal, etc. Their iLO/iDRAC/whatever also implements IPMI, which you can access via free and open IPMI tools as well as their proprietary tools.

IPMI 2.0 includes serial over LAN, but that's text only console redirection. If you want graphical console redirection, you need to use a proprietary tool from your vendor, your server's BMC has to support it , and you have to pay for the license for it. Dell calls their IPMI implementation "iDRAC", and every motherboard always has the latest BMC capable of doing whatever, but you have to license iDRAC, iDRAC Pro, iDRAC Enterprise, etc. The cheapest option when buying a server is iDRAC Express, which gives you IPMI and none of their proprietary shit. You get power on, off, cycle, read the (hardware) system event log, configure the network settings of the BMC, and console redirection to a serial port. For Dell, you also have to enable redirection via COM2 in the BIOS if you want serial over LAN.

IPMI doesn't touch the fucking OS. IPMI lets you build tools to do that, but that basically means spotty support for Windows servers.
If you're running graphical Linux, you need graphical console redirection, as Guspaz does:

SSH is my primary interface to the server, but sometimes you've got to get on a box locally, like if you mess up something network related, or you mess up a change to grub, or who knows what. It's not common, but I don't have a serial terminal, so having video output when needed is very important.

The only ways to get graphical console redirection are to use a hardware solution connected to video ports or to use proprietary vendor shit. IPMI does not do this. IPMI console redirection is text only. Read the spec.

Comment Re:16 nm vs 14 nm (Score 1) 110

I'm not particularly familiar with either company's process, but it's been a couple of generations since you could actually make meaningful comparisons based on the quoted nm size, because everyone has different smallest features that they measure when deciding that they are Xnm. That said, we passed the end of Dennard scaling a long time ago. You'd expect the same chip to be consuming about as much power, be slightly more able to dissipate the heat. It may also have less leakage, though that depends on a number of other factors.
