"the courts in the US, at least, are far from agreement on questions of fair use"
The saga of a song being found to have violated copyright - not because of lyrics or stanzas, but because it emulated the "look and feel" of Marvin Gaye is arguably when USA copyright law jumped the shark
"but I suspect the outcome of a "robot" doing something illegal will put the onus on the robot owner."
I'm minded of the plethora of patents for "Doing XYZ well-known and unpatentable business process ON A COMPUTER" which proliferated in the 1990s until the courts ruled they weren't novel and rapped the USPTO over the knuckles for not rigourously inspecting things.
Unfortunately the USPTO (and other countries too) have taken the attitude that income matters more than novelty, therefore virtually every application is approved and it's up to the courts to deal with challenges. I wouldn't be at all surprised to find patents again being issued for perpetual motion machines
GIven past history, patents & etc will start being granted for "XYZ, but USING AN AI"
We already know that "training" on existing data is a really bad idea - the way AI insurance and legal software ended up with systemic biases against various racial groups is a classic example of how it perpetuates rotten input unless that input is utterly ruthlessly audited - and also a good example of how users took the outputs at face value "because the computer said so"
If I wanted screeds of bad code, I'd farm it out to Bangalore(*). The only advantage an AI will have in the longer term is that it will undercut even the cheapest lousy human programmers in the "why output 12 lines of solid code when 8 pages of obfuscation wll keep us employed for decades?" stakes
(*) Sooner or later some other city/country will take that crown
"Copyright law was designed for books"
also, it was only valid in geographic areas (the USA famously built up its technology by ignoring european copyrights and encouraging rampant IP thef) as well as having a term limited enough to ensure that creators COULDN'T rest on their laurels and simply rely on residuals forever
The system is broken in a lot of ways, but GPL has turned the efforts by Eisner et al to its advantage
It should be noted that patents and copyrights were BOTH suspended in Britain by James 1st because of rampant abuses and shakedowns not that much different to those being seen today - and weren't reinstated for over a decade (with new rules more similar to what we trhink of when we see the words today)
The reason for killing the system "as was"? It was harming the economy and stifling innovation
GPL is simple at its heart: comply with the license conditions or you're into copyright violation territory
The license says you must show your sources or the license is void. There are no restrictions on commercial/non-commercial use other than that
ie: You're more than welcome to make money off it, but you MUST NOT hide the origins
If I wanted people to use my code unattributed and hidden, I'd release it under BSD license. GPL exists because of companies which kept taking code, putting it behind paywalls and claiming copyright on other people's work
The bigger issue wasn't the sale of failing companies, it was the disasterous social policies bankrolled by income from oil/gas
In addition, there were no steps taken to prevent harmful monopolies being created (hello BT) along with selling off stuff paid for and funded as public health initiatives (hello water companies - cholera was their impetus) that were turned into abusive monopolies
One could do it the way Kosmos 2251 did...
More seriously: This is wel beyond range for a laser broom to be effective (and yes, we should be developing these), however it's an ideal task for an ion tug such as MEV1
You don't actually need much delta-V. Simply tweak the orbit to go highly elliptical (relatively easy to do) and the atmosphere will do the rest for you
" I would like an explanation about how this problem is addressed"
It gets hot - white hot. Ablative or active cooling of control surfaces is needed, or you come up with some way (as with reentry vehicles) to divert most of the hot air around the airframe without touching it
If you have a flight time of only a couple of minutes on a one way trip, cooling is less of an issue
The DF21 and its cousin the DF4D don't need to be nuclear armed for the task they have
A nuke in such an instance is useful if you have a delivery radius of a few hundred metres
These things are quite capable of reliably putting a hole in the flight deck. In many ways you don't need any explosive at all when the kinetic energy is considered - a mission kill is more than adequate to send the aggressor home, without actually sinking the vessel
(China has more than enough ASBMs to rain a bunch down and force an escort group to expend all defensive weapons before picking off the ships themselves unoppose, or to drop them around the main vessel to make a point that they COULD sink it if they chose to do so, but they want people to go home. The biggest unknown right now is that the leadership is suffering from having the same guy at the top for too long. There are good reasons WHY democratic countries change the management periodically - it stops people from being utterly surrounded by yes-men)
"When I asked for the source media, I was pointed to *two pallets* of Windows\Office retail boxes in a store room"
At one point in the early 1990s I worked for a government radio station for a while and discovered that they had installed "multiple unlicensed copies of Windows 3.1" (yes, it was that long ago)
It was actually 30% CHEAPER to buy retail boxes than a volume license, for.... "reasons" (mostly down to the disties gouging heavily, because they could)
This comes back to the issue of medical egos. Everyone has their own best system and the aviation model of standardising _everything_ to minimise risk/mistakes plays second fiddle to massaging those egos
Once upon a time (not so long ago), pilots were much the same too. Things can be changed.
This kind of thing is a long-solved issue - lawyers did it in the 1990s when data warehousing due to the extreme costs of real estate in places like New York City
reinventing the wheel inventing a new conversion and records system for every single local trust is beyond stupid
"They were so efficient using it's arcane series of shortcut keys. Whereas the newer windows based GUI system (name escapes me) but it took so many clicks to do anything emis users hated it."
There's nothing preventing both modes to be provided.
Being GUI-only is the kind of mistake that can be cured by introducing the dev's face to the desk in front of him - at speed
The worst part is that this stuff is tunable.
I'm guilty of having done this - enabling everything that's there to see what people actually want/don't want
Once you have feedback you can remove the uncesseary items for various groups - manglement-interest stuff not showing up on the coalface forms unless people go into advanced mode, etc
"The UX people worked with the people who had spare time"
mistake #1 in a lot of orgs.
Those who turn up "in their spare time" for such consultation sessions are the LAST people you want to be involved
Find those "who don't have spare time" and schedule breaks in their workload so they CAN attend
LEAs have a fundamental failing inasmuch as poor counties are poorly funded.
The same applies to local NHS funding and housing
National bodies are vastly more efficient and not as subject to local politics (which is VASTLY worse than national level stuff due to so few people taking an interest in the antics of their elected local officials)
Don't take my word for it, look at how well national level education, health and housing departments do in places like New Zealand (the isolation and low population density there, with high costs of keeping offices interconnected demonstrates economies of scale quite well: It IS more efficient - and when politicians threaten an national service more people take note. Localism is a path to privatisation and carving up for profit)
The problem across the world is that the ratio of taxpayers per pensioner has been falling as people live longer and have fewer children
Sensible countries saw this coming and made investments for the future. Most english-speaking ones simply pretended this wasn't going to happen and told taxpayers to party on
The result is that GenXers are likely to face a pension eligibility age of 75, simply because there's no way pensions can cover them retiring at 65 - and it's likely to be means-tested too
Funnily enough, this isn't a particularly chinese problem.
The REASON strict consumer protection and company liability laws exist in most western countries is because this kind of thing used to be commonplace in them too (and still is in many places)
It's a stage every country goes through
"For GM and Ford, perhaps they didn't calculate their risk properly."
This in spades. They looked at the front page of the Toyota Way manuals (minimising stock) without actually reading the whole bloody thing
The Toyota Way is about reducing stockholding to minimum WITHOUT putting production at risk and constantly evaluating the risk/benefit from doing so.
After the 2011 earthquake affected chip supplies Toyota reevaluated risks along with manufacturing time and started holding around 12 months' worth of semiconductors (up from 3-6 months) - plus they didn't cancel chip orders.
This is why they were able to keep building vehicles whilst other makers cancelled orders, then got caught with their pants down when reordering got them sent to the back of the queue (they were apparently relying on being "too big to not prioritise", not realising they're tiny customers in the semiconductor market, mostly buying low-value/low-margin devices)
TSMC et al would have happily bumped Ford/GM/etc up the queue if they'd been willing to pay for the privilege - the fact that incomplete vehicles were stockpiled is an indication that they didn't see it as worth the extra cost
"Rumor has it that GM has also had to retest, repair and recertify hundreds of pickup trucks due to rodents chewing on wires while the trucks were waiting"
Which makes the point that vehicles should be built to prevent this being a possibility in the first place. Rodent damage is a constant theme in some areas - it's not exactly a new phenomenon
It was moves against free trade which led into WW1
Specifically, British interests taking retaliatory action against Germany taking advantage of the existing free trade structures around 1860 which led the rather alarmed Germans to start building their own navy to protect their merchant fleet and increasing German militancy+nationalism
Does this sound familiar in the context of the last few years?
The principle is relatively simple - a hollow pellet full of deuterium/tritium is dropped into the chamber and as falls through the middle, hit with a synchronised pulse of lasers from all sides sufficiently powerful to collapse/vaporise the walls and drive up pressures/temperatures inside to sky high values, setting off a small fusion "explosion"
It's somewhat akin to throwing a pea into the air and shooting it at the top of its arc
To make a working power source, you need to rinse and repeat at least 50 times per second, accurately tracking where the pellets are (gas flow is goign to be turbulent and jostle the things around) and figure out a way of extracting the heat whilst containing stupidly high levels of radioactivity - the chamber walls are going to be bombarded with neutrons and that tends to make most materials which absorb them (except water and berylium) _very_ radioactive (including the business ends of the laser emitters)
Fusion power may be "clean" but it's not going to be "waste free" or "non-radioactive"
Hohlraums were originally envisaged as a way of making civil power, but the applicability for weapons simulation is what gets the bills paid
Most of the R&D funding for ORNL's MRSE was provided as part of the Aircraft Nuclear Reactor Experiment. Nobody involved believed they could actually make a safe flyable nuclear reactor but it was a convenient cover story to get money for the research
> (which is pretty much the same way it's been in fusion reactors for 60 years - the priority isn't to produce energy, the priority is to provide fissile material, with the energy being a byproduct).
ITYM fissoin reactors
This was the fundamental sin of the ORNL Molten Salt Reactor Experiment - if commercially adopted it would have broken civil nuclear power generation free from the shackles of being dependant on the waste products of weaponmaking(*), therefore would have meant that the "enrichment plants" would stop being dual-purpose and start being subject to nuclear limiitaion treaties
(*) 3% enriched uranium is the WASTE product. The desireable substance from a mliitary point of view is depleted uranium - that's the feedstock for making weapons-grade plutonium. "Highly enriched uranium" is a conjurer's misdirection tactic for the most part - it costs so much that anyone wanting to make a bomb out of it would find it cheaper to simply _buy_ their enemy instead (it's far too radioactive to be used in an implosion weapon, as is plutonium made from uranium with natural levels of U235 - and uranium made from thorium (U233) has so much U232 in it that attempts to use it have always resulted in _decreased_ bomb yields to the point of verging on fizzling (see: operation teapot)
At least China is still working on their MSR reactor, although they've been quiet since it fired up a year ago...
There isn't enough to support ONE commercial fusion power reactor
That might change but the easiest way to produce it involves molten salt nuclear reactors and those and a relatively easy heat (energy) source with very low waste output and were proven 55 years ago
Putting it in context - the world's entire annual production of tritium and deuterium isn't enough to keep ONE 1GW fusion reactor fed for a year
This is one of the fundamental issues with fusion. Yes, duterium is in seawater (nordic hydro, etc) and you can make tritium from lithium but the former is expensive to extract and whilst 7% of all natural lithium is a candidate for tritium production the latter works out at $50,000 per GRAM
(Also, heavy water is relatively dangerous. It turns out that many life processes rely heavily on quantum tunnelling of hydrogen protons and deuterium essentially "doesn't tunnel". This shuts down mitochondria, stops photosynthesis and prevents DNA unzipping, amongst other issues)
Fusion is "the future" but we need to drastically cut carbon emissions NOW, not in 100 years, so waiting around for it to be ready isn't a viable strategy (If CO2 levels get too high then sea level rise or climate change is irrelevant - if raindwater gets acidic enough (carbonic acid) to start affecting plant life then a runaway process becomes unstoppable - this isn't theory, it's happened in Earth's past and took less than a decade to go from "oh shit" to "Dead Dave, everybody's dead. The entire planet's dead, Dave" (Gaspacho is optional)
Don't forget that 3MJ output (not watts, joules) then has to heat a carrier substance (water or CO2) which then has to feed into a heat engine of some description
In the end it's all just a fancy steam boiler driving a turbine (Yes,. I know about electric field direct generator ideas but they're pie in the sky until someone actually makes an actual working model) and the best you'll get out of one of those with 3MJ thermal energy in is about 1MJ of electrical energy out
Once it's running continuously then you can start talking Watts (joules per second), but until then it's just an impulse - they still haven't managed to get two firing in a row, let alone the 50-100 times per second needed for power generation
Hohlraums were theorised in the 1980s and first attempted in the 1990s. Taking this long to achieve ignition puts them vastly behind Stellerators or Tokamaks at a similar point of development and it's taken over 50 years to go from those achieving a pulse to running for a couple of seconds
Fusion is like rocket science - the conceptual parts and theoretical physics is relatively easy, The ENGINEERING is where it gets difficult - and the more we discover about subatomic particle interactions the more we realise is still needed to discover. Thanks, Heisenberg!
These days the new silver or gold is oil
Having oil has seriously screwed up the economies of virtually every country which has discovered it, usually ending up worse off than they were originally - the economy becomes utterly dependent on selling it and every other industry atrophies because oil income has made the currency ride high and local products become too expensive to export, whilst imports become relatively cheap
Even the UK has suffered this. The disasterous social/economic policies of the last 45 years have been underpinned by oil/gas income which masked the unsustainability of government actions. Now the oil is drying up but the habits persist
You can't eat gold
ANY currency is only as good as long as people agree it's good and accept it for trading
When 4th century Rome took action to deal with centuries of coin debasement, the unintended effect was that people looked at the new coins and started refusing to accept ANY Roman currency - despite the new coins having more silver in them than the old ones.
The Empire was over in less than 18 months after that
Nuclear power plants cost more to run than coal ones - this is why there have been so few planned since the 1960s
It was costs which was the main driver of abandoning plans to build nuclear and sites in-progress. not protesters. Environmentalists have never suceeded in stopping anything which was actually profitable and are frequently used as an excuse to get out of marginal businesses without penalties being imposed
Change the underlaying nuclear technology to something which costs 80% less to build/run and reduces waste dramatically (ie: Molten Salts) and the math changes markedly - but Molten Salt nuclear technology has been illegal since 1972 in the USA (you can have molten salt and you can have nuclear, but you can't put radioactives in your molten salts)
One small datacentre I was involved with has contractual wording forbidding water piping in the server room or data store
Every piece of plumbing in the building was routed through the ceiling space of the data store and the builders refused to remove it "because you aren't the customer" (facilities was)
water pipes for the radiators on the floor above were also routed through the server room. I proposed hacksawing them out and was threatened with GBH by the site foreman
