Hackers hijack Tesla Model S from afar, while the cars are moving

Re: What's worrying is that it's a Tesla

Corporations aren't afraid of no liability. That's why they're structured the way they are: to assure scapegoats. That's why executives NEVER go to jail unless it's for a PERSONAL crime.

PS. Don't forget radio jammers are illegal under the Telecommunications Act AND they're easy to detect. And the only legal alternative, shunting, has two strikes against it in a car: windows and lack of a ground.

IPv4 apocalypse means we just can't measure the internet any more

Re: NAT and firewalling and stuff

OK, since you spoke so politely.

1. For NAT to perform two-way communications, it can do one of two things:

(a) the inside computer can initiate a connection to the outside. The NAT records this and maintains the relationship for as long as the connection is open. Once it closes, the relationship is removed. Now, this usually only works for stateful TCP-based connections (UDP doesn't work this way so requires something cleverer to deal with it) and only if the connection is initiated from the inside. Now, it works most of the time because most connections on the Internet are TCP-based and from the inside.

(b) A skilled user can tell the NAT to forward certain classes of incoming connections (like specific ports) to specific machines. This is the usual means for a home user to expose a server or similar thing (like a P2P unit) to the outside. Otherwise, the server has to rely on outside help, making a bridging connection to some point on the outside.

2. Going back to 1(a), since HTTP, POP3, etc. are all TCP-based (stateful) and initiated from the inside, NAT can maintain these connections.

3. Gamers have one of two options. They can either open ports (solution 2) or use solution 1 to establish a bridge connection to a point outside. Your friends link up there and the system then passes the connections along.

One of the arguments for using NAT is that it's a different kind of firewall operation: furthermore, it's one that (by design) has to block incoming connections by default, providing a line against automated attacks (targeted attacks can get around this by exploiting already-opened connections the way web exploits work). The counterargument is that in IPv6, this is little more or less than another firewall, and you can achieve the same function with a second (or better) firewall.

Furthermore, it's not NAT in general that's being frowned upon: it's one-to-many NAT they don't want (because the spirit of the Internet is that any connected device should be reachable by any other device if it wishes to). Especially at the ISP/carrier level, this makes many endpoint invisible by force. They have no problem at all with one-to-one NAT, and indeed many techniques brought forth to mask a subnet's map rely on things that are essentially one-to-one NAT. It's like with the UNIX philosophy: one fundamental assumption is that policing should be a program's (or in this case, device's) own responsibility. Trouble is, reality intrudes and you find misbehaving UNIX programs and badly-configured endpoint devices, so the NAT proponents at least have a point. What some are wondering, though, is if the "automatic" shielding can't be achieved simply by offering a firewall with something like a "drop incoming by default, allow outgoing by default" ruleset.

Re: Work of the Devil, etc...

"So we can internet enable ebvery grain of sand, which is good because connectivity internetofthings future"

It's basically a way to ensure we don't run out again, much like how ZFS uses 128-bit provisioning to ensure filesystem limitations are never reached in real life (and before you quote 640K, physical limits would be hit first).

Want a Dell printer? Unlucky – they've just stopped selling them

Charles 9

Re: Hands up

I wouldn't know about lasting five years. First off, I buy all my printers secondhand. Secondly, I tend to replace printers when I find bargains on better ones, repurposing the old one or turning it in to a charity shop. But for the record, I haven't had any of them really break except for a LaserJet 6L that IIRC tended to lose grip with its main paper feed roller after some time (a problem it shared with the 5L).

I believe this is specific to the UK in this case. Besides, I think most Dell printers in America are rebadged Lexmark printers rather than another brand. That might make a difference.

Re: An interesting move

Just a heads up, I checked out PureVPN in the past but ended up at nVPN (nvpn.net). I find them to be more flexible for experienced computer users. They offer dedicated IPs, port forwarding, and HTTP and SOCKS5 proxies. For all that, I found $60/year to be a reasonable price compared to the other options at hand.

Re: business perspective

There's the third option: that it's CONDITIONALLY profitable, that is profitable if and only if they alone control it. If anyone else gets it, that's competition that could later intrude on their existing business (making it counterproductive). So for them only two states are acceptable: THEIR control or NO control.

Re: I think...

"Of course current law is not nearly so useful, but laws can be changed....if folks will get their dander up and come running into the streets demanding their rights."

But the only way to do that is to risk their livelihoods, meaning it's a dilemma. Not much good to march on Washington only to find your employer packed up and left in your absence. It's one reason any mass protest like Occupy Wall Street fizzles these days; protests generate headlines but they don't pay the bills.

Re: That's Fine, Unless They Change Transmitted Patterns Or End Run Using Lasers

"We must agree with our enemies they won't make changes to their transmitted patterns OR to switch to laser guidance for the last few seconds. Then it might work."

The can may be able to adapt to patterns (the lookup table may be based on frequencies and strengths to distinguish ground from aerial radar). As for the laser, that may have limited functionality in an air-to-air encounter where the quarry is moving at over Mach 1 and can turn pretty sharply, which is why most A2A trackers today have pretty large fields of "vision".

In case you forget down the road, in case you're off the beaten path, in case the photo is being used as evidence (investigator cameras will want geotagging to solidify photographic evidence in court). There are many legitimate uses for a geotagged photograph. It's all a matter of knowing it's there and judging whether or not to use it. In my case, I leave it on, but then I only use the phone camera in ways where knowing the location doesn't hurt me any (pictures of public locations where the GPS coordinates are already known or social settings where everyone already knows the location).

Not necessarily. The service is based in a non-US jurisdiction. If the US government sends them a takedown notice, they can respond that Hong Kong's (and thus China's) sovereign laws do not respect these notices. What can the US do then?

Re: Umm

It does if it's machine-readable, meaning something like a computer can follow the link at your direction. A web browser does more than read directions, it follows them, too. Think of the difference between a car YOU drive and one that can follow signposts and drive itself. In the latter case, if you post a misdirecting direction and get the self-driving car into a trap, that's a crime.

Being charged based on actual use is still metered, since it essentially means you're being measured and charged based on that measure. Remember back in the dialup and early mobile broadband days? Not only were they metered, but they were overcharged. Do you really want to go back to that?

Because the alternative is metered Internet, where you get charged by the megabyte (this actually applies upstream, with upper-tier providers that either have to pay their way or agree to a peer exchange and maintain a balanced load). There was a time people were faced with this with their dialup or mobile data plans. Since so much of our lives uses mobile data, it tends to create more headaches than we want, which is why people tend to prefer flat rates, both for Internet and for telephone so that they can set a budget and not have to worry about going over.

I wouldn't mind terribly if these claims can be controlled by the law in some way. Like testimonials can ONLY display typical (let's say modal to avoid wiggling) results. I will admit that "up to" claims will be hard to control since for some firms that's all they can promise (due to lack of control). But a law that demands as much truth in advertising and as little wiggle room as possible would be nice. But as they say, the devil is in the details.

"In most cases, the weakest link is the connection to the property."

Depends. If you're connecting around the world, there's plenty of potential for a weak link along the way. If your destination's pretty obscure, you raise the chance for a weak link. There's a lot of factors beyond your control, though I will admit if you're at the mercy of a DSL link in the middle of nowhere, you've got a pretty lousy hand to start with. I wouldn't know; I've had cable modem since about 1998 and wired my own house. With FTTH as the local alternative, the cableco's been steadily improving the service and are now starting to roll out Gigabit service (via DOCSIS 3.1) to counter. I don't trust the max speed, but the data cap that goes with it looks tempting.

Re: Common practice in the early 80's game programming to wring the most out of the feeble

Thing is, while DynaRec and JIT can be compiled high-level, self-modifying code usually isn't compiled but assembled, as to do it right you really need to go low-level and hand-tune everything. It takes a VERY specialized language to be able to practically repeat the feat with a compiler.

Re: Self modifying code.

But if there's one place where wringing the most performance still exists, it's something like a console emualtor, and emualting a Wii or PSP counts as pretty much the pinnacle of console emulation for the time being (no one expects anything above those to be feasible anytime soon, as it was around that time that computer performance stopped climbing so rapidly).

Re: "I think you will find RAM is quite a bit faster than in the days of a PDP8."

" Having the instruction cache manipulated manually by an application as 'workaround' or 'kludge' written all over it (or as we all tend to find out the hard way, "An Accident Waiting To Happen")."

That's why they sometimes call it the bleeding edge. The programs in question are trying to extract every last bit of performance from the CPU (because they're doing something pretty demanding like emulating a CPU and other hardware from less than ten years ago) because raw performance becomes the baseline by which everything else becomes possible for it.

Then you'll be doing it for the rest of your days, I'm afraid. The main reason ad slingers stopped using them is because people tended to ignore them. It's like with much else ad-based.

Re: Theres plenty of room...

"We live in a world where people can do price comparisons online."

You assume the average mobile customer is savvy enough to know this. My experience is that most people are stupid and just want to get by their day. They'll listen to word of mouth or (gasp) check out the deals in the windows. And since many people in the upper crust depend on stupid people to maintain their standard of living, stupid people will never go away.

"Its the same with broadband. We all know BTs claim to have the best wifi in the country is bollocks."

No we don't. Remember P. T. Barnum's words: "a sucker born every minute."

"How many of you want to rush out and sign up for BT on the strength of their crappy router?"

More than you think.

"Give me a £50 a month SIM only genuinely unlimited package and im in. No throttling, no peak time bullshit, no tethering restrictions (another bullshit arbitrary restriction) and no fucking about."

They'll never give it. Limited spectrum and cartel behavior guarantee this via a captive market, leaving you with the Hobson's Choice: take it or leave it, and then find yourself in the lurch when you REALLY need to be accessible in the field.

"Also, why not make mobile networks regional rather than national like the energy companies. We'd all be better off that way since operators will be responsible for smaller areas of coverage and wont be tempted to only install infrastructure in 'profitable' areas."

Because spectrum is a NATIONAL resource, controlled by the central government (has to be that way due to other radio functions like weather, television, and especially mandated things like the military, plus it's inherently an interstate/interregional business). Makes it pretty much an all-or-nothing.

Problem is, price tends to drive things more than anything, especially for the large chunk of the population where price is the overriding concern. The problem here is that you and your competition end up bleeding yourself in price wars. This ends up in Pyrrhic Victories.
