Private key on the server???

Why is it ever transmitted - surely the appropriate way to do auth forwarding (which is useful) is for the server to pass the auth requests back to the client (which may pass them back to the next client etc.) until it's at the machine with the private key

Aircraft now so automated pilots have forgotten how to fly

Re: A bit of editing might be useful...

The issue with that analogy - and the analogy is being discussed - is that drivers aren't nearly as well trained, or continuously assesssed, as pilots, and there is always a safe position available: stopped! That isn't possible with aircraft.

The issue on the roads is that there are a large number of people who massively overestimate their own skills, and the damage they cause is frequently to those outside their vehicle....

Council of Europe gets tough on net neutrality

John Robson

The two services (residential and commercial) would have been sold with different traffic management policies - so that's fine.

What I find slightly odd is that they can't now traffic manage - for instance - P2P download traffic to be of a lower priority than VoIP traffic.

That's basic QoS management, and appears to be banned under these rules.

I am absolutely with them that no one VoIP provider should be preferred over any other, nor should one streaming audio provider be favoured over any other, nor should any streaming video provider be favoured over any other, no HTTP(s) source.... no BT source...

But the idea of prioritising VoIP and streaming over HTTP(s) over BT is a sane method of traffic management IMHO.

Re: Attack on free speech?

I'm not convinced this is an attack on free speech - you're free to post said pictures (if you still think it is in good taste) after an hour - but you allow an amount of time for the families to be notified in the proper manner.

It's an hour, not a week, and certainly not "never".

I'd go with the victim exclusion, but I can't see why the "professional" media should be any different, nor first responders (although they might want to email it to the paramedics, but I would guess that facebook isn't the way they do that) - stuff still hurtles around (anti-)social media pretty fast - wherever it was taken from.

A location and a stock photo would be adequate for the news media for the first hour...

Of course legislating for sense is never going to work...

Researcher criticises 'weak' crypto in Internet of Things alarm system

John Robson

Re: Optional

It came from the "remote control via pocket computer"

There isn't any indication that any of the comms are encrypted and there is a tendency in devices nowadays to be WiFi only - often not a recent version, forcing all devices to drop to a lower standard...

That this has ethernet is one good point IMHO - of course the rest of the security is still needed

Re: Optional

Hardly technophobic..

I can see the benefit of having some devices on WiFi - mostly user devices, but I doubt that an ethernet port shouldn't be significantly more expensive than a WiFi chip and antenna.

My NowTV boxes aren't mobile, they don't need the mobility of a WiFi connection, neither does an alarm system - which is presumably wired in to the house...

My Blu Ray player has an ethernet port on the back... One of the things I looked for when I bought it...

The benefit of using wires is that the airwaves need be shared by fewer devices. Wires make good a spatial division multiplex and avoids all the issues of whatever the latest wireless security issue is, as well as not limiting your next gen router to an older WiFi speed, compromising the remainder of your devices.

Re: Motorists stay clear of North Wales

"But, as is quite evident, there's an endless stream of idiots all too happy to follow them. So, my point: how do hidden cameras help deter dangerous driving and/or speeding? "

Well, it would increase the likelihood of detection significantly - and that would mean that people wouldn't expect to get away with it.

It wouldn't take long for people, even the idiots you reference, to work out that if they speed then they *will* get busted, and therefore pay the appropriate price.

At that point it becomes an easy decision NOT to speed.

Currently the chance of detection is so small that there is no deterrent value.

Re: Motorists stay clear of North Wales

@AC: I am aware of that saying - If you really think that being banned from ONE form of transport for a week would lose you your job/house/family then you need a reality check.

Sure the bus might take a bit longer, or friends might have to collect you en route to work. That's the point - driving is not a right, it's a privilege.

By putting everyone ELSE's lives at risk (which is what you are doing) then you are demonstrating that you are not fit to keep that privilege. Driving is the only obvious situation where people are allowed to take a lethal weapon into public and operate it in close proximity to the general public...

Re: Motorists stay clear of North Wales

The first of those links was a speed camera at the side of the road.

Why should speed camera locations be advertised from miles off? Global compliance isn't aided by saying "We only check here".

The second is to do with speed cameras being operational at night - when arguably you should be doing less than the speed limit anyway since your visibility is reduced.

The problem is not with the police catching people speeding, it's with the courts not enforcing bans:

http://www.bbc.co.uk/news/uk-england-essex-33378386

Easy solution to not getting banned. STOP SPEEDING.

I'd rather went for a "one week ban on first offence", then 2,4,8... system.

It might make people think a bit about their speed. Combined with a 10% of monthly income fine... and you might be motivated to stay within the posted limits (they're limits, not targets)

Re: STS comparison

"I don't think that the comparison of the STS with the Falcon 9 is valid; the STS had to cope with re-entry but the Falcon 9 doesn't, which will make a big difference in the refurbishment costs."

Well, it does have to cope with reenty - that's what the third burn is for.

It doesn't have to cope with reentry from orbital speeds however...

Re: Bah!

"A proper space station would house people without the need for excessive special training. It would have enough gravity to make life relatively simple and provide proper windows so the visitors could see why they built the damn thing in the first place."

Has enough gravity - well, the ISS experiences about 90% of the gravitational force that we do on the surface - the thing is, it's in freefall - that's kind of required for an orbit...

You could set up a fast spinning station, but then you have lost half of your usable surfaces within the structure...

Windows of course are a rather delicate point. Both from a "resisting air pressure against the vacuum of space" and from the "a grain of sand could shatter this" perspectives. That's why there are 7 holes in the ISS YouTube.

"And it should float higher than a gnat's whisker away from the atmosphere, so it doesn't need so much shoving to keep it aloft. Which means we need better lifting engines so people can get there."

You can either keep boosting the ISS a little, or spend an inordinate amount more fuel *every* time you transfer people/cargo...

I'm again going to suggest that the people at NASA might have considered the various options regarding altitude, and decided on where it is for a reason...

Re: Real numbers would be interesting

Not all payloads are the same - the largest payloads will always require the first stage to be forfeited, but slightly smaller payloads afford the spare capacity for some 'descent fuel' to be carried as well.

(Slightly lighter payloads don't have enough spare fuel to return to base, hence the barge landing option)

Of course given the cost of the stage it might be more economical to split the big payload in two and assemble it in orbit?!

As for designing things for reuse - it's a good thing that cars are single use items... and planes... and bikes.... and shoes....

Oh, wait a moment.

They don't have to be very much heavier, certainly not when compared with the all up mass of the rocket.

Re: Lohan loophole

"It still has mass but I stick with the -ve weight"

It has positive weight, but the air it displaced has a greater positive weight. With most objects you don't need to consider the mass of the displaced fluid.

Take a supertanker - does it become weightless when placed on water?

No, it still weighs alot, but it is supported by the water around it.

LOHAN still weighs what it did before, but it's supported by the air around it.
