Comment Re:It's called the key (Score 1) 1176

I have to agree with the parent - neutral or just shut the key off (though obviously not all the way to lock - that too would be seriously bad). Neutral has the downside of possibly leading to engine destruction depending on the failure mode (though very unlikely with modern ECUs and injection), but it's better than destroying the whole car and killing people in a wreck. I know some dingbats might not think of that in a crisis (my ex wife being a great example), but surely the police would think of that as a better idea than trying to clear miles and miles of freeway for this guy to burn up all the gas.

Comment It's about power (Score 1) 590

Quite frankly, solar energy isn't that dense (only a couple kW per square meter) and aircraft require a tremendous amount of power to actually be able to move useful loads at useful speeds. Jet engines are usually rated in pounds of thrust, which I'm too lazy to go find the thrust-speed-altitude relationship to convert that to power. A number I could find was that a single C-130 turboprop engine is rated at about 3.3MW of output. So with four of them for one of these cargo haulers, that's about 13MW of power. Even assuming 100% conversion efficiency and 3 kW/m^2 at cruising altitude (it's roughly 1kW/m^2 at sea level, and 1.5kW/m^2 at 6000 feet, so this is probably close or a bit generous), you'd need 4333 square meters to collect enough power. The wingspan of a C-130 is 40 meters, so you've basically only got at most maybe 160 square meters of collecting area on the wings. And that's at 100% efficiency. Now consider that the overall system efficiency for photovoltaics would be around 10%, and that you'd need storage so you could take off, land, fly in the dark, and fly through clouds, and you've created something about the size of that flying quad-copter fortress from Avengers without all the actual coolness (or, say, adequate lift).

Nothing beats good old liquid hydrocarbons as fuel sources in terms of flexiblity and energy density.

Or that you don't give a rat's ass about 99% of the stupid shit your "friends" post on FB. Most of those people who instantly tried to friend me were people from high school, many of whom were too cool to talk to my nerdy self back then. I didn't like them then, and they've been out of my life for 15 years. I couldn't care less that their baby did something today. Heck, my aunts, uncles, and grandparents use it all the time, so I don't think age is the delineating factor. It's more that I have way more things in my real life than I can keep up with, and I'd much rather be social over a pint at a pub or a MakerFaire or a reprap get-together than on some website with people that don't matter in my life anymore.

I kept my account for about three months, mostly to see if I could find a couple old girlfriends and see what they were up to after my ex and I split. After that, I removed any content I could (I basically only ever uploaded one bland picture and some trivial details) and then told them to delete it. It was just adding to the noise side of the SNR in my life, so I just decided I was done with it. It does seem to be deactivated, but I suspect the Eagles were right on this one - you can check out any time you like, but you can never leave.

Oh, and just for good measure...

Comment Re:No seatbelts? (Score 2) 307

If you're sitting down and not wearing your seatbelt, you're a dumbass. I fly all the time (and used to fly jumpset on cargo jets, who don't tend to take the "easier on the passengers" route), and have lost two laptops over the last twenty years to sudden drops and ceiling impacts. I've also seen my coworkers hit the ceiling and then drop to the floor, often resulting in at least a nasty headache. This shit happens; wear your seatbelt. And yes, if you're instructed by the flight crew while in US airspace, the FAR dictates that it's a lawful order you must obey.

Comment Re:WTF? (Score 1) 321

Selfish in what way? Does the world not have enough individuals breeding like rabbits?

As a former DINK and now one of a pair of SINKs (divorced a couple years back, still friends), I have to agree that I don't see what the big deal is with kids, or why people think we should all have them. WTF do I care if my genetic lineage carries on? I'm dead eventually regardless. Makes absolutely no difference to me. I share with the future generations in other ways - I create, I share, I teach, I mentor. I just don't do it on my own biological spawn. I have no great and noble family line to carry on and I'm just a pretty average guy (and one with a congenital genetic defect that doesn't matter until after the usual kid-producing cycle, and then kills you slowly and painfully - not looking forward to my 60s). It's in fact better that I proceed with being a rich capitalist yuppie pigdog and let my particular mutation die with me.

The core of it really was that we both wanted to do things with our lives that didn't involve taking an 18 year break to raise kids, so we did.

>Time to join the 21st century grandpa. FILE* leaks.

Hell no. And get off my lawn.

printf() isn't typesafe, but it's a fuckton more readable than all that cout formatting stuff. Also, the fact that it's not typesafe isn't really an issue if you don't suck - trivial unit testing will pretty much show any problems immediately. Besides, gcc/g++ is nice enough to warn you about egregious ones now.

FILE* leaks? I assume by this you mean when sloppy programmers fail to close their files and you start burning through file descriptors. Sounds like a bug to me, and again, stop sucking. Or do what we do - throw an object with a destructor containing fclose() around it. Then you get all the awesomeness of of FILE* (including those awesome formatting commands like fprintf and fscanf) without the danger of your file staying open when something goes nuts.

Why on earth would you want memcpy() to call anything? It's a low level byte move. Anybody with five minutes of familiarity with it should know that. If you wanted something different, use the assignment operator.

void* have all sorts of applications, most recently to me in writing architecture neutral VMs where really all the native machine knows is that it's moving around some sort of pointer.

Now the custom string and array classes? That I'll agree on. Troll on.

Comment Re:Read things before you sign them. (Score 1) 467

One of my coworkers was asked to sign something similar when he joined the company, and he just amended the agreement to say that work only owned what was developed on work time or with work resources. Legal just signed off without any argument.

Clarifying this stuff up front would have been best, but you can approach your HR/legal department and explain what you're doing. Most of the time it's just there to keep you from developing something great related to your field and then running off selling it to whomever, rather than keeping it in house as a competitive advantage (or selling it through the company). My employer could care less if I design/sell stuff on my personal time, as long as it's not related to work.

Comment This is news? (Score 4, Insightful) 117

Seriously? The entire Rio Grande Valley - which pretty much covers a north-south line right down the middle of the state - is a rift valley. The continent has been splitting and spreading here for millions of years. It's an interesting measurement, to be sure, and it's nice to have confirmation, but it shouldn't come as much of a surprise.

Comment Re:Yeah right (Score 2) 326

Well partially, but I'd argue the addresses have a lot to do with it, too. My home subnet is 192.168.77.0/24. My firewall blocks anything coming from the outside world bound for 192.168.77.0/24. That's nice, but doesn't really ever do anything because damn near every router between me and a potential attacker drops packets that are to or from the reserved networks, because it has no idea where to send them. About the only way it would be a viable attack is from somebody who had control at my upstream ISP.

A non-NAT scheme depends - almost entirely - on my firewall not sucking. I try, but I have in the past screwed that up when changing rules and haven't realized it for days until something seems to be a bit wonky. My motto is if you can't get a packet to it, you can't attack it.

Comment Re:Just do it (Score 1) 544

Raising a big scene is exactly the wrong thing to do. Gets everybody worked into a pissing match. The correct answer is just to know your rights, assert them, and calmly call in bigger guns if really necessary.

And yes, I speak as someone who has raised the stakes with a rent-a-goon when I was being harassed on a public sidewalk. I called the real cops. They showed up, asked a few questions, and told the rent-a-goon to take a hike and learn that his authority ended at the edge of their property several hundred feet away.

I take any erosion of my photography rights very seriously, given the irrational paranoia society we've lived in here in the US for the last decade. I mean for fuck's sake, in the case above I was standing on a public sidewalk in broad daylight with a giant f'ing SLR (1Ds III and a 28-300L, which isn't a small combo for those who know their Canon gear). It's not like I'm trying to hide or be stealthy about anything, yet the rent-a-thug seemed to think I was some sort of imminent security threat.

CmdrTaco - it's been a great fourteen years, and of the sites I started reading when the web really started exploding, /. is the only one of the original batch I check at least once a day (and sometimes just sit in the reload button, waiting on new stuff). You've provided millions of us with interesting reading and commentary, and built something (along with Hemos, CowboyNeal, Roblimo and all the other infamous editors of the past) that's acted as a common nerd meeting ground for years. Can't thank you enough for the thousands of hours of my own personal and my corporate overlord's time that this site has stolen. Best wishes for the future.

I remember trading emails with you back in 1998 or 99, when a group of us at Iowa State were trying to get slashcode to run on our machine. Eventually got it with some of your input, but mostly we were just honored that one of the internet's first nerd celebrities would actually respond and try to help. Ah, the good old days.
