Tesla is treading a knife edge here. Right now they're on the correct side of it: they should have a right to sell. But what happens when the first buyer wants a third party to maintain the vehicle and Tesla decides not to cooperate?

Tesla could quickly find themselves on the wrong side of public wrath.

That's what it exists for: getting money for school activities.

Not really. Linux inherently does everything UAC does and more. SELinux tries goes beyond that.

Instead of just needing permission to make changes to your computer, SELinux requires a process that you gave permission to make a change to your computer get permission again to make a different kind of change to your computer (and again and again and again).

As reported, it also forbids executable stacks. Ordinary Linux only requires programs which use executable stacks to declare themselves. The vast majority of programs don't need to, so they're protected against stack overflows.

A stack overflow in a single-user game running with ordinary account permissions is, quite frankly, not a security issue.

Have you looked at whether a faulty interaction with DNSSEC could be at fault?

This is what the alumnae association at your school is for.

If you read the article (I know, I know) you'll learn that he uses industrial grit, also known as glass beads, which are tiny bits of glass that are reasonably spherical and ridiculously cheap. The quoted lens cost in the article is $0.17, but unless I'm misunderstanding something, like how special the grit is that he's using, or what kind of secondary selection process is required to pick out beads that will make good lenses, that should be closer to 0.17 cents, not 0.17 dollars.

For a complete and immediate answer, click the first link in the first sentence of the article.

Humanity faces a five hundred million billon trillion dollar loss of income due to premature extinction of the species.

Please, also don't act like your the first person ever that this has happened to. It's been standard practice for at least the last 15 years I've been working IT in schools in the UK.

Your post is constructive right up to phrase "the last 15 years" which apparently justifies how little your network reveals to the surveilled about the actual extent of the surveillance, even to the point of having software installed that they know little to nothing about on their own equipment that could open back doors to the device when employed outside of the school network if by some extraordinary turn of events proves to be slightly less than 100% bullet proof in its coding, implementation, and deployment. Nothing ever goes wrong with WEP or SSL.

Would it damage the small little minds to know more about how this all became "bog standard" without so much as a public whimper? Probably. Does that mean your Slashdot post is filtered on your own school network? Probably.

In my world, forged SSL certificates should be clearly marked as such. There should even be a "forger identity" field and a "forger authority" field (containing the pertinent parental agreement UUID).

None of this would interfere whatsoever with your legal authority to protect your network or your success in achieving this protection. It would increase the awareness of the surveilled of what externalities they have actually taken on downstream of their agreement with you to allow you to do so.

The fact that you've been doing this for fifteen years already without any of this in place is a sad argument.

If this is the school's equipment so that the school absorbs it's own externalities of having badly-coded surveillance kits forcibly installed (I'm guessing the rock stars on that coding team were on the guaranteed forcible-installation side of the house) and the equipment is emblazoned with a giant warning "abandon privacy all ye who input here" there should still be a giant warning screen that comes up whenever a user tries to access a major financial institution (I'm told the government tracks the identities of these organizations) which warns the user "you are attempted to access a financial institution through a forged SSL root chain which is potentially a far leakier pipe than regular SSL, are you really sure you want to do this?"

So you're justified in doing what you do, but you're also so damn sneaky about doing it, that fires spring up in public opinion when the least of what goes on is exposed to public discussion.

No need to hammer the state of affairs in the daily consciousness so that these public fires don't flare up. Because fifteen years.

My bank has a security mechanism where they show a set of images unique to my account so that I can detect impostor sites that entice me to enter my credentials where they shouldn't go (the impostor site doesn't know the unique images associated with each banking account). There really should be a law against these security fingerprint images being conveyed through a forged-certificate SSL proxy no matter how legitimate the usage agreement. Once those images are scraped and laundered, one more safeguard we've be taught to trust is down the spiral tube.

If it's rational, necessary, and you're proud of it, do it out in the open as democracy conceptually demands, with plenty of loud warning signs where the externalities impose heightened risk.

Yeah. First thing I do on new Linux installs is disable SELinux. Linux does satisfactory job protecting against the common problems (like buffer overflows) without SELinux. SELinux adds hassle well past the point of diminishing returns for improvement to security.

Too many people suffer and die from too many diseases that we more or less understand, but can't effectively treat.

Yes, this is what classical Greek rhetoric describes as a regressive mirage: the more you learn, the worse it gets, no matter how diseases you cure along the way.

Here's the amazing thing. Understanding tends to outpace effective intervention. Any snooker player can tell you which ball on the table he'd really like to move next. It's rarely the ball he's presently shooting at. In Genomics, we're talking 30,000 balls on the snooker table, and the snooker table is gravity golf in a twenty dimensional space. Even with your trillion dollar Laplacian pool cue, you're struggling to pull off exactly the shot you want.

When I was young and we were on a long trip and the moon was hanging there on the horizon, I always wanted to go faster, so we could see the other side.

Then I got a little bit older. Perhaps a month older. And I thought to myself, "you know, there are reasons why this is probably not going to happen the way I want it to".

Boss, most government contractors can't even *think* about H-1B's lest their government customer catch wind of it and grow nervous. Given my career, I would know.

Like I said, if it appears to you that the majority of companies want H-1B's, you're simply looking in the wrong place. You won't find a good job hanging with the day laborers out by the highway. That isn't where the good jobs are.

Howdy,

A sales engineer is not a salesman. The salesman and sales engineer are a team. The sales engineer's job is to help both the customer _and_ the salesman understand which products in what combination do the things the customer wants to do. In fact, he's usually the one who helps the customer understand what exactly it is that the customer wants to do. The customer starts with only a vague idea.

He doesn't have to convince the customer to buy. That's the salesman's job. And he doesn't tend to do the nitty-gritty engineering work either. But he puts a huge stamp on what the customer deliverable looks like. He's the guy who first draws it out on the back of a napkin over lunch.

If you like technology AND you like people AND people find you easy to understand, sales engineer is a pretty fun job.

Personally, I find people to be exhausting. Sales engineer is not the job for me. But it's awfully hard to be a teacher if being around people wears you out, so I make the assumption that you find the interaction enjoyable.

Sounds to me like you're looking in the wrong places.

I live in the Washington DC area where virtually every fast food cashier is hispanic and most speak around 10 words of English. During a McDonalds lunch some time ago, I happened to overhear a job interview. The kid was clearly unmotivated but his allowance wasn't cutting it. Towards the end, the manager ask to see paperwork with his social security number or a birth certificate or whatever, the documents on the government list for proof of citizenship. The kid didn't have any. The manager asked what his social security number was. The kid didn't know. So the manager told him to go get those things from his parents and come back.

When the kid left, the manager called over one of the assistant managers and began filling him in on the interview. He explained: "if the kid comes back, we'll probably hire him because he can speak English."

You wanna compete with the day laborers hanging out by the highway, of course you're going to lose. The day bosses in the pickup trucks aren't looking for white guys. Apply to a company that isn't in the 10% of the bottom feeders.
