"IP4 was handed out very unfairly"
Saying that demonstrates a fundamental ignorance of why IPv4 was created in the first place.
It was a self-described kludgy-hack intended to be used for no more than 4-5 years, whilst final versions of the real Internet Protocol were developed. There were never more than a few blocks intended to be used, which is why 4 billion IPs was regarded as plenty.
That protocol (Internet Protocol Exchange - IPX) turned out to be utterly unusable, so IPv4 ended up having its life extended repeatedly.
It was clear by 1992 that it needed replacing and even at that point there were less than 20 million people on the Internet or using UUCP.
It _should_ have been replaced by IPv6 before 1999, but by that stage there were already too many IPv4 allocations and too many vested interests who didn't want to spend money to changeover, so we're in the situation we are now.
It's been like watching a train wreck in slow motion. Staving off IPv6 by going to dynamic IP assignments, then NAT and extensions on that may have been well-intentioned but the long-term results have been damaging.
Re: Problem with organisations everywhere...
"Quite like the idea of the ITU getting involved as posters below have mentioned, as it is slow but pretty stable which is what is needed."
NO. DEFINITELY NOT
If the ITU was in charge, you'd have the same intercarrier treaties and telco control over bandwidth we used to see before the FLAG consortium broke up the cartels.
The ITU works on behalf of the companies which are members of the ITU, not on behalf of the endusers.
The US govt (DoC) might be widely suspect, but they've repeatedly shown they have the right interests when it comes to final Internet oversight. Bear in mind that those on the ICANN board are first and foremost there because they are political animals, not there for their technical/engineering skills.
Re: Pretty nasty
" I'm not defending FTDI here, they seem to be on very shaky ground if it is in fact deliberate as everyone is assuming"
The linux driver code snippet posted elsewhere in this thread proves it's deliberate.
"If you are using / planning on using a FTDI chip today and have the ability to swap "
Underscoring that, there are at least a couple of legal devices which are pin-compatible with the FTDIs, so the only change needed is to the driver and the BOM.
"Whether it's a western company deliberately buying surprisingly cheap reels of components from cheaparsechinesechips.com rather than the official distributor in order to shave 10% off the BOM"
Analysis of FDTI and workalike serial devices shows they have about the same fabrication cost. It's not unusual for fakes to get into production lines with _no_ change in price.
This isn't much different to the situation with ELM327 chips and ELM have studiously avoided anything which goes near this kind of behaviour (They just identify the device as fake and treat them as an old chip revision which is slower/much less capable than more recent devices)
Re: Odd reactions
"Why is it that you expect FTDI to play nice with components it can positively identify as fakes? "
Tort law for starters.
They can refuse to operate with the device, but to deliberately reprogram the device so it can't work AT ALL cross the line from legal to illegal behaviour.
A representative of Rolex can't take a fake Rolex off a customer's wrist and smash it on the ground without a court order and Gucci can't go around spraypainting fake handbags on the street. Doing either would land the perpetrators with jailtime.
Re: Very dumb idea
"So FTDI gets no money for the parts so they say "you are not using our VID/PID and our drivers" for free and they are the bad guys?"
If FTDI popped up a message saying the chip was a fake and refused to run, or operated only at 1200bps 8/N/1 then that would be OK.
The moment they deliberately rewrite the VID/PID without a court order, they're into illegal destruction of 3rd party hardware (You can argue the finer points of them being reprogrammable, but for the end user the device is dead)
You can't just arbitrarily trash devices for fake parts even if your intellectual property is being compromised, there are procedures in place to deal with this kind of thing happening.
It's also important to note the fake VID/PID are NOT a clone device. They're an independently designed workalike using completely different silicon. The IP violations come from FDTI labels on the front (most don't have this, by all accounts) and using a FTDI assigned VID/PID.
This can and will blow up in FDTI's face. They can't justify the action using their driver contract - this was installed by Windows update and the message wasn't seen, plus the laws about Unfair terms in consumer contracts are applicable in most cases.
"We've already got the case going on where the gov.us have demanded Microsoft to give access to data stored in Ireland "
Not quite. If the PATRIOT act had been invoked, MS would have handed everything over without a word of dissent.
The case in question is important for other reasons.
I fail to see how Amazon EU will fall outside of the Patriot act, short of removing ALL business operations from the USA (Even having a subsidiary company or a single office in the USA is enough to make a EU outfit fall under its jurisdiction)
Re: Why ?
"How does Ireland make any money by being a tax haven ?"
By charging a lower rate of tax than everyone else, all the companies cluster there - and with the complicated double handling that was going on the irish govt was getting closer to 2% tax rather than 20%, but 2% of "all EU profit" is still a lot better than 20% of "profit from this country only".
The whole merry-go-round is being closely examined at the moment, with the result that the irish govt may see a cash bonanza as previous 2% payments are judged as "tax dodging" and the full 20% paid. This is very much "heads I win, tails you lose" as far as the irish govt is concerned - they'd still have the lowest corporate taxation in the EU, so companies would still benefit from being headquartered there.
one possible way
"The companies Irish arm holds a load of patents, trademarks etc. They charge the UK arm a license fee for using them. This "loophole" can't be closed (easily). If company A licenses IP from company B, that is a valid business cost and company A can't be expected to pay tax on it."
It can pay VAT though (which is a consumption tax).
If I, as a small business or individual, buy an IP license from Microsoft UK, then I pay vat on that transaction even if nothing actually changes hands.
When Microsoft UK pays license fees to Microsoft USA, no vat is paid on that transaction.
There's a bunch of long and complicated reasons given for this kind of shenanigan, but it boils down to the age old argument of "Our employees pay tax, why should we pay too?"
Re: If you were a shareholder
I'd be looking less at the share value and more at the dividends.
Stocks can go up, or down. Up is nice, but down happens too.
More importantly, a stock only has any value when sold. Up to that point it's just scrip and I've seen "blue chip" high flyers evaporate overnight when the markets lose confidence in them - which is germane, because I think the earnings potential of facebook or other "social media" sites is vastly overestimated.
I was doing this in the 1980s
But then again I was installing/servicing pager transmitters (amongst other things) too.
Anyone remember the old RTTY<->ASCII converters and their ilk knocked up using a UART and some supporting logic?
"With a variation estimated at 0.1–0.2% over the last 2000 years, it just doesn't follow that such a tiny variance could cause such major climate swings. "
The output has varied over 50% in the last billion years (Sun's getting hotter/brighter).
The issue is that the entire system on earth is fairly finely balanced and we don't know where the short term tipping points are or how much things will move when disturbed away from the current balance. If you've ever played the game of trying to take the bait off a live rat trap without getting your fingers whapped you'll know it doesn't take much movement to have consequences.
"would it not be possible to transfer heat to the cold of space via an external heatsink "
1: You have to get the heat from where it's being generated to the heatsink
2: You have to make sure your heatsink isn't facing the sun or it becomes a heat collector.
3: Because there's no convection cooling effects, you need a vast radiator to achieve high levels of radiative cooling
4: Which means you need a vast sunshade, etc....
Radiation shielding for humans is relatively easy - very few particles have the energy to penetrate a water jacket a few inches thick and what gamma radiation gets through that can be stopped by appropriate lead sheeting.
The big problem is getting that much water into orbit without using a nuclear _launcher_ (Orion)[*]. It'd probably be easier to lasso a comet for the raw materials.
[*] There are loads of nuclear thruster designs which would work in space, but the real engineering problem is getting out of the gravity well and atmosphere in the first place.

Re: Are you a slave?
(redistribution to those not in need for a small fee and mucho promises)
That's the premise.
The reality is that those in need get a small fee and the govt keeps the rest to pay itself.
It's the same scam that has charities paying their staff 6-figure sums.
...the trend is towards warming, there's no reason that can't mean harsher winters and hotter summers.
If all the goats die off, how will I clean the windscreen on my Hummer?
"Better explanation would be a chronic lack of funds. "
There's plenty of funding, the problem is it's paying for management summer homes, not roads.
Classic example was a new bypass road around 2004 (I forget where but it featured on the Beeb at the time) which was closed for major repairs before it even opened as the contractors had skimped on the roadbed vs specifications and it started coming apart in freeze-thaw cycles. It had to be ripped up and started over.
Properly built road beds don't fall apart. Ask the Romans. Some of the best roads in the UK are laid over bases they put down nearly 2000 years ago.
Re: LED lighting
"Ah, that's because the regulations quote wattage and not lux/lumens/candelas per m2."
There are definitely lumen limits in there, the problem is that the eye's perception of brightness isn't linear, vs what a photometer shows (the eye is at least 10 times more sensitive to green than red as a f'instance)
Re: Fuse wire
"Almost impossible to retro-fit to an old vehicle, but previous proposals for a voltage of about 40 to 48 volts are being resurrected."
Given most EV and Hybrids run around 600V for the traction battery, pretty much any voltage is possible if you put your mind to it.
Re: Cruise control
"HGVs overtaking other HGVs while being prevented from going over 56mph, that's what *really* slows down the traffic on M-ways."
Or HGVs in all three lanes (illegal, but happens regularly)
I like the dutch approach. If there are 2 lanes in each direction, HGVs are prohibited from overtaking - if caught (and they WILL catch, as they have cameras all along those stretches), the driver gets pulled over a few km up the road (regular occurrance between R'dam and A'dam with french drivers who didn't give a shit about the law).
Re: Mr ChriZ Advanced Motoring
"in times past bad driving habits such as aggressive tailgating at speed would have been spotted and punished; these days the idiots simply get away with it."
I suspect that the rise of the dash/rear cam will help curb this issue a bit. They're mandatory equipment in Russia and will probably become so everywhere.
A couple of people commented that aggressive tailgaters back right off when they clock the camera peering at them through the rear window and I was bemused when they were proved right.
Re: Mr ChriZ Advanced Motoring
"But I didn't see you brake."
He probably wouldn't have seen you brake anyway. A decent driver isn't soley focussed on the car in front, (s)he's looking 12-20 seconds down the road to see what the traffic's doing and adjust accordingly.
I'm looking forward to self-driving cars. It gives a chance to seriously increase the requirements for getting a driving license.
By the way, what's the deal with the advanced driver's course in the UK coming with an INCREASE in driver premiums? (I checked. It's true)
"George Buehler in his book on yacht design comments somewhere that a correctly maintained Lister engine is unstoppable and asks how the country that produced the Lister could also produce the Jaguar."
Amen.Those and Mirlees: I had to do daily maintenance on a pair of 300kW 12 cylinder Mirlees diesel generators at one point., They were a thing of awe and beauty when running. Donkey engine providing the juice and air to get them started was a small Lister. They were all 60 years old when scrapped and still ran perfectly.

"Just be aware that when you don't touch your breaks your break lights don't come on!"
You're also decelerating a lot more slowly.
"If you're not careful you'll have someone to close behind you running into you!"
In which case they were 1: following too close and 2: not paying attention
There's a rule about 2 second following distance for a reason (it's expressed in metre per km/h or yards per mph, but it translates exactly to 2 seconds) and it's not to allow twats in fiestas to pull into your safety gap at 90mph.
Re: Depends on assumptions
"So much so that it's a standing joke for the apprentices at the dealers to be given these jobs then made to find the missing part which involves taking the back of the car apart..."
A friend and I made up a gooseneck with electromagnet for exactly those situations back in the 80s..A suitably modified boroscope would work better these days - and bear in mind that a strong enough magnet _will_ move the loose nut/part to where you can get at it, even through sheet steel
Re: Depends on assumptions
"that even changing a light* often requires a workshop and workshop tools,"
ISTR some EU design rule changes a couple of years back mandating that bulb changes must be doable at the roadside. The result was to hasten the move to leds, as they're not regarded as a user serviceable part.

"It's surprising how many people think a car gets better MPG when going downhill if they go into neutral!"
Depending on the car, slope and engine temp they may be right.
Using the Torque OBD app, the instant milage changes between overrun and coasting on a few local hills is eye opening (90 vs 180mpg when cold, 180 vs 240mpg when hot). I suspect that modern engines put a small amount of fuel through even on overrun to keep the cat hot (or light it in the first place), even when the manifold pressure is down around -13.5psi.
There are a bunch of techniques to improve milage. Ripping out weight to the extent shown is a bit radical, but it's probably improved reliability dramatically given my experience of 1960/70s british cars (somewhere along the line, "made in britain" became a warning label)
Other hacks: lighter/synthetic gearbox/diff oil, ditto on the engine, roller tappets, narrower tyres/higher pressure. The comments on the lights are valid, but they make so little difference that it's not worth bothering with. As for the alternator, dump it entirely - GM proved in the 1950s that an exhaust turbine-driven alternator was a lot more efficient, but had trouble with reliability under heat loads. Belt drives put asymetric pressure on bearings and sap far more energy than could ever be recovered by hacking the regulator circuitry. There are a couple of designs for electrical generation using turbocharger housings - and spinning at 15-25,000 RPM means the entire alternator can be a heck of a lot lighter/simpler.

Re: Interference on the line
There's no law against commercial interference with the regulators.
Given that the people making the decisions come from the telco industry and go back to the telco industry, they know that side their toast is buttered on - and what happens to regulators who displease their future employers.
Openreach needs to be completely cleaved off from BT(*). Once a fully independent lines company, empowered (and required) to sell duct space to 3rd parties, things would change rapidly, as they have elsewhere(**)
(*) Completely separate shares, board of directors, offices, administration and CEO. Any favouritism shown to any player gets heavy punishment.
(**) New Zealand has changed from a posterchild implementation of how not to privatise your telco, to a place with vibrant competition in the 3 years since they split the incumbent telco from its lines operations - as a condition of getting rural broadband installation contracts. UK.gov had the same opportunity and blew it.

"Surely Amazon/Starbucks etc are prime candidates for automation? "
Nope, people are funny about wanting to be served by a human. What you'll see is increasing levels of table service,
Warehouse picking is increasingly automated, as are other boring/dangerous occupations.
I was wondering when Foxconn's workers would object to robots.
Japanese workers did when the robots started encroaching on jobs which weren't dangerous or dirty. In particular, there were heavy objections (and actual strikes) on car assembly lines when they moved beyond the welding and spray shops. As a result, japanese manufacturers eased up on automation.
That was the point when other asian countries started taking their business.
"Seems to me automation just means goods get cheaper and most people always find a way of earning money to pay for it."
This is exactly what happens. In a post-scarcity world the service industries are dominant.
Re: A dark future?
"I can't see us of even getting a chance of that until we can get an abundant, non-polluting energy source which is still many years into the future."
Abundant? - check
Non polluting? - how about "very low levels?"
Many years into the future? - prototypes built in the 1960s, commercial versions likely in 10 years
Profitable? - that's the unknown issue and unless it is noone will get to use it.

Re: Will become a familar issue in coming years
"The kind of rethink that we would need at that point is far beyond what most people are capable of."
The 3-4 day week is one way of ensuring employment, but unless it comes with the same wage as you're getting now, it's not worthwhile.
In any case, the population bulge of the Boomers is going to make life hard for everyone soon - especially in China where it's even more pronounced.
The vast majority of government welfare costs has been in pensions for decades. Unemployement is only 10-15% of the total, but it's easy to demonise the unemployed as slacking parasites and because there are so few of them, their votes don't count - unlike what would happen if there was radical pension reform.
Re: Will become a familar issue in coming years
"The reason the BRIC countries have done so well is a direct result of this push to cut costs, they are in these countries for the low wages and light regulation, nothing more."
If robots can build things for lower cost than humans, then the production is best sited close to the point of consumption - which is going to hit BRICs hardest unless they develop economies not dependent on exporting products or importing jobs(outsourcing)
Re: Russia is a competitor to Galileo.
(BTW, strategically, three is a stable number. Every time one player gets ahead, the weaker two will assist each other until the advantage is nullified.)
You'll be happy to note that there are already 4 in action:
Navstar (USA), Glonass(Russia), Beidou/Compass(China, still being deployed but usable now), DORIS(France - mainly used for satellite/groundtstation positioning)
With 3 more on the way:
Gallileo(ESA), INRSS(India), QZSS(Japan),
Whilst the west may lump China and Russia together, historically there's no love lost between them and all alliances have been by necessity, not desire (China may sell the Norks Oil and Electricity for instance, but it's the Russians who created the country and keep Fatboy-un afloat)
"They will probably have some nominal contribution as an extra timing reference - but it looks like it's an insurance job"
The constellation order was specified with 4 spare birds to account for for launch mishaps. Because so many are being built the insurance value of individual units is low (they're production line items) and there are enough spares in hand to cope with the losses.
The real issue is that this pair was intended to complete the test cluster and they can't be used for that even if their orbits are stabilised, so the end result is yet more delays before Galileo goes into production use.
Losing a 4-stack of these on an Ariane launch would be the real disaster, but the Ariane V has been extremely reliable. The ES has already been heavily used and the relightable/long coast-time EPS upper stage has already seen action, getting ATVs to the ISS. One of the big advantages of the EPS is that it can be relit for deorbiting after payload deployment, which means less space junk to contend with.

Re: Won't reduce the need for power stations in the US
"When a bulb I almost never use burns out, like say the bulb in the hall closet, I replace it with an incandescent because they're cheapest. "
60W incandescent - 1 quid at tesco
4W LED - 4 quid at tesco (less when they're on special)
The most annoying thing about a dead lamp is that they almost always happen at an inconvenient time.
Re: @ scatter
"Thankfully halogens only last 1,000 hours also so they'll disappear just as quickly as GLS lamps once the transition starts."
My last set of MR16 and GU10 incandescent purchases were 10,000 hour jobbies. They lasted about 5 years before I replaced them with CFLs and then LEDs (Tesco's leds/cfls have been reliable, ones from other sources (I'm looking at you B&Q!) have not been.)
I finally got irritated enough with the RF and infrared hash emitted from all the ES and BC CFLs around the place that I changed them this year.
16W "corncob" leds easily outperform 21W ("100W equivalent") CFLs and apart from not having that pesky 30 second warmup period have a better colour gamut too.
The externals will be replaced with leds when the CFLs in them start to die (which should be next year) and at the same time I'll be considering "upgrading" to the robot ones which track heat sources as the existing cheap fittings are starting to craze due to UV exposure. I've seen the robot ones in action and you'd be amazed how fast a prowler can run if the light swivels towards him- and stays pinned on him as he moves. The only current issue is the cost.
Re: @ scatter
"what makes the difference is that they have a motion sensor, so there's no groping for the light switch."
This is going to be the big trend in security lighting too.
CFL AND Halogen based lamps need to be on for longer periods, else the on/off cycling kills them in short order. LEDs can switch on and off as often as required (assuming there are no issues of thermal creep on the heatsink and substrate), which means that outdoor security lighting can move towards a "dark skies" model (which attracts more attention when the lights come on than constantly on lights do.)
Even if this is counteracted by reducing the spread of constantly-on floodlights mounted high to keep them out of missile range of spotty herberts and putting in more "spot" security lighting, the overall power consumption trend will be "downwards"
LEDs are pretty much invulnerable to shaking from a thrown stone, unlike a hot filament - and the local oiks regularly knock out "inconvenient" incandescent security lamps around here.
Yes, power consumption from heating is likely to rise long-term, but only a fool would install an electric radiator based system when heat pumps already give heating operational (and installation) costs comparable with gas-based systems.
Re: Life cycle
"Household tungsten lights were cheap to manufacture and presumably to recycle - but with poor energy efficiency over relatively short lives."
"The cartel’s grip on the lightbulb market lasted only into the 1930s. Its far more enduring legacy was to engineer a shorter life span for the incandescent lightbulb. By early 1925, this became codified at 1,000 hours for a pear-shaped household bulb, a marked reduction from the 1,500 to 2,000 hours that had previously been common. "
It's worth noting that if you run an incandescent lightbulb at 5% over its rated voltage, it gives 10% more light but only lasts half as long. You get that much variation in supply voltage along the street from a distribution transformer.
Re: Let there be light!
"My large town switches off all the street lights at midnight - leaving only a few high level clusters on major roads."
LED plus sensors means that they can be dialled back 90%, but still fire up as cars/people go under them (the lamps communicate to adjacent poles, so it's not just the one you're under which lights up). This technology has been around a few years now.
As for energy costs, the single most expensive part of any streetlamp's operation is getting a bloke to change the lamp. Traditional ones are rated in on/off cycles as well as hours, so switching 'em off early may not make them last any longer and does bugger-all to save money overall. That sounds more like someone with a fetish for dark skies (Any amateur astonomers on the council?)
The pitch black conditions and increased nighttime accident rate sounds like a perfect oppportunity for compensation lawyers to wipe out any savings made - and then some.
