There may have been less available data altogether, but what data was available indicated people shopped in and near malls, hence a lot of B&N in malls. But with malls seemingly slipping away, B&N will have to relocate or adjust more radically.
Marijuana lifestyle startup – The Kind – Manifesto rules
Without doubt an issue that needs reform (which I believe is coming - there's a lot of campaigning around it).

Would be surprised if many people outside the country knew about this problem though. Of course, its possible I'm wrong which is the reason I asked in the first place.
Sapphire and ruby are both aluminum oxide - i.e. 'alumina' - just with different kinds and amounts of impurities.

Yes, it is technically the stuff you get when you throw aluminum powder over a fire and it lights up and burns brightly. But the crystals you obtain that way are very tiny.

I would love to be proven wrong about that.
Fully agreed. I support fairly high taxes on it, but full legalisation. And it is true that people still need convinced, but different places are starting experiments now. I've heard the US puts anti-drug language in contracts and stuff - if true, the faster the US loosens up, the more quickly change can be possible.
> The idea that I can explain or argue anything presupposes that some things are true and other things can be shown to follow logically from them or be disproved by contradiction.

The idea that communication is dependent on pre-existing notions of truth and logic is flatly false. Now you might presuppose those notions when you communicate, but that doesn't make that presupposition necessary for communication.

> Whether people commonly seek truth is a separate question from whether truth exists.

True :). I'm not trying to convince you that truth doesn't exist. I'm trying to convince you that you can evaluate the phrase "truth does not exist" without pre-supposing the existence of truth. This is because you can (and people commonly do) evaluate such a phrase on attributes other than their 'truth'.

The phrase "you may be right" can mean all KINDS of things from "I don't have a definitive counter argument" to "It is possible your statement is true" to "I don't want to argue about that anymore".

I think you are too focused on how you tend to perceive the world and communicate about it. People don't all think and talk the same way you do and assuming that they do is doing them and yourself a disservice.
You're assuming a very particular kind of nuclear fission machine.

Or how about the other way round, given the economic morass they try to get as much bang out of each buck spent as they can?

After all, the reason for said morass was the private debt accrued during the 80s.
Above, you wondered about "what possible incentive" there could be against obsolescence, and said you weren't being rhetorical, you really wanted to know.

@aljones gives such an incentive.

Now, you try to cook up particular parameter values under which this reasoning would not apply ("what if you displease them in one way..."). What is the point of this?
That's fair - I didn't know there wasn't a difference, so I was going off my own impressions.
I didn't mean to downvote you but accidentally clicked on the button and can't go back.

However, I do disagree with your point. I'm pro-nuclear to the degree that it's economical, and found the article to be somewhat insipid due to grandparent's reasons.

Just as there are plenty of people that are irrationally anti-nuclear, being irrationally pro-nuclear is no better at all.
To really solve the social problems, the sale needs to be legalised.

Making the sale a criminal offence puts money into the hands of organized crime, drives up the prices, forces addicts to steal to buy their drugs and leads drug users to take "worse" drugs like methamphetamine because "better" drugs aren't easily available.

Drugs need to be made legally to ensure quality, to remove harmful impurities, to ensure the dosage is consistent and predictable which reduces risk of overdose, and especially to ensure that when a person consumes "drug A", they do not in fact get a dose of the more addictive/harmful "drug B" (i.e. methamphetamine).

Governments stand to make tax dollars off marijuana too.

There's a trail of logic that must be followed - if it is OK to buy and consume drugs, why is it not OK to sell them?

The only caveat is that methamphetamine should remain illegal to buy or use. The idea being that people will use "less harmful" drugs than methamphetamine because they are available cheap, easy and clean. The strongest possible justification for legalization of sale and use of drugs is to minimize usage and supply of the greatest of all evils - methamphetamine.

We need to accept that people want to get high. You can't arrest that human desire out of existence. We can however remove the harmful effects of criminalization of the sale of drugs.

Criminalization fills prisons, wastes police and legal resources, destroys families, prevents people having functional lives and creates both organized crime and petty crime.

N.B. personally I'm not interested taking in any drugs except alcohol and caffeine so I'm not angling to be able to get high. I wouldn't take em even if they were legal and free.
>You can build a lot of PVs and turbines in the same amount of time, and place them closer to where they're being used (reduce transmission loss). You can also place them on top of buildings (reduces AC load by 2%) and on top of parking lots (reduces car heat and urban heat island effect).

That was not the point. The argument was that nobody can build all the hundreds of nuclear plants that we would need. How can we build the millions of PV's and thousands of turbines?

>You're not going to electrify poor parts of the world with big, expensive, centrally-controlled fission plants.

Why not? It's probably the cost/watt that matters.

>transmission loss

Most of world population lives close to coastline.

>It will cost over $100 BILLION to clean it up.

Nuclear power might still be cheaper as a whole.

From an outsider perspective, I viewed Ireland as somewhat socially conservative. "Somewhat" meaning that while a significant proportion of the population has liberal/progressive views, I felt that segment was less than majority, therefore unable to swing the vote on issues like this.
> There is simply not enough uranium for a full build out of 3rd generation nuclear

This is really important and is often avoided to be discussed: even if the 10% of all world's energy needs are covered by the nuclear energy at this moment, we know we're using some 70 Ktons of uranium per year. Then to use only nuclear energy we'd need 700 Ktons per year. Currently identified uranium resources total 5.5 Mtons, which would last for less than 8 years of such use. Even if those aren't the exact numbers, that are the orders of magnitude.

That's why the breeder reactors would be needed as a "solution," and at the moment they are still experimental, especially regarding the fulfillment of their major promises.

The current state of FNRs:

The two only "commercial" plants currently planned are in Russia (from mid-2020s, U+Pu nitride fuel) and China (from 2028, U-Pu-Zr fuel).

> You have to draw a line somewhere, and the English were the first to actually subjugate the head of state to their system of laws.

I can't think of any reasonable standard where England actually has subjugated the head of state to their laws and is also the first to have done so by that standard.

I mean, surely we aren't holding up the military purge of Parliament that produced the Rump Parliament and that Rump Parliament's creation of the "High Court of Justice" and its prosecution of the King as an example of the rule of law... At best, that would give the English credit for the creation of the revolutionary kangaroo court (and, even at that, it probably wasn't original.)

And, even if you were to credit that as establishing the rule of law (and certainly, a lot of the language popularly used -- e.g., in the US's own revolution -- about the relationship between the monarch and the law stems from that prosecution and the propaganda around it), you'd have to recognize that that was hardly a durable principle established in England, having been somewhat forcibly repudiated when everyone who participated it that was caught by the post-Restoration government having been executed for their participation in it.

The right to fork is a prerequisite for users' freedom and without it the software is not free. The right to fork is about having complete control over the software that you're using. And it's usually a fact - either you have that right, or you don't, instead of being a warm and fuzzy social ideal, like the issue of "users freedom" tends to be.

Because the second you said "users freedom", you're in danger, because what constitutes a "user" is unclear. Is a user a person that pushes buttons providing input for your program to produce its destined output? Or can a user be a programmer as well? Because depending on its needs, different users want different freedoms. And for example I do not consider AGPL to be open-source (or free software for that matter) because modifying code without redistributing the binaries is simple usage for a developer, which means AGPL imposes restrictions on usage, being a freaking EULA.

But going back to our subject, dual licensing, take a look at projects that are dual licensed and usually you'll notice that the choice of the license had nothing to do with users freedom, quite the contrary, after all, without serious constraints dual licensing wouldn't work.

I was pretty happy with my HTC One M7 until a month ago when I saw that it wouldn't get Marshmallow. I went out and got an M9 on the after market and all I can say is, I'm glad I didn't pay full price for it.

2 years later and the only definite "improvements" I can cite between the M7 and the M9 is the inclusion of an SD slot and the tap-to-wake option on the screen. I understand that both of these were in the M8, so I probably could've saved myself $200 and grabbed that.

Additionally, many people are completely unaware of the vast variety of fission machines of all shapes and sizes -- rocket engines, ramjet engines, space power reactors, research reactors, isotope production reactors, submarine power reactors, Army mobile power reactors, etc. -- that were produced and operated 50 years ago. To say nothing of the variety we could build with today's metallurgy, CAD, etc.

I am surprised everyone disagrees with this, it's really common and the basis upon which a consumer society is based.

Clothes don't need to break, lightbulbs can be built that last forever, cars can and should run indefinitely when we can build aeroplanes that don't fall out of the sky and the performance of animations on an iOS device do not need to degrade substantially every OS release.

Apple release new versions of their OS to support the App Store (which make billions every year) not at all to increase the longevity of devices but to decrease them!!

I assume some of you think this is a paranoid conspiracy or something??
The Ivanpah plant isn't a great example. The tech is already going obsolete, and it's producing far below theoretical effectiveness. It should be able to produce a terawatt. Fundamentally, it's because solar is immature technology, and nuclear is mature. So what would the efficiency and cost be for a mature solar plant? And how do we get to maturity?

If a solar plant could hit 50% of the energy efficiency on the same land (and the poor-performing Ivanpah plant reveals that it's possible), that raises a question of why we need the cost and complexity of nuclear.
A significant portion of the article is devoted to such issues.

"Even if people are aware of the health risks of cooking over open fires (and many are not), they are reluctant to abandon cooking methods embedded in their culture."

"Women had stopped using the stoves because they didn’t like the design or because the stoves broke, burned more wood (not less, as intended) or didn’t get foods hot enough."

"Indian women surveyed by the Stockholm Environment Institute said they prefer to cook roti, a flatbread eaten with every meal, in a clay oven using a mix of firewood and cow dung because they can both fry and bake the bread and the fuels improve the taste — much like some American cooks like the flavor of meat grilled over charcoal."

"The affordable ones are inadequate, and the good ones are unaffordable.” (How do you expect a group of people unable to afford a stove to afford retrofitting their home with a chimney?)

Your chimney solution solves none of these problems. When attempting to address an issue in developing nations, it's importent to analyze exactly how people are implementing he solution on the ground. Cultural grandstanding as seen in these comments does nothing to solve the problem.

Wait wait wait, you're going to have to provide a citation for this claim that corrosion is not a problem.

I was told by faculty with joint appointments in matsci and nuclear engineering that it is a major issue and that while they've developed some alloys that look reasonable in the recent past it's still academic research unproven in scale up.

Holding molten salts is really hard... they corrode the heck out of even high end commodity stainless steels (this I know from professional work). Protective coatings help for sure, but they crack over time, especially with any thermal cycling. Inconel and similar alloys maybe, but it's really not straightforward to block grain boundary corrosion! Add to that neutron embrittlement...

I've not kept super up to date, but it's hard to imagine that these alloys went from academically unproven to industrially certified in the last seven years.
I agree with you but remember that Ireland and the UK are islands, which immediately puts them in a better position to deal with smuggling compared to countries that share long land borders. I think this is why island nations are generally a bit more conservative - it's much more practical to control imports.
So the core of this trick is to point the stack pointer into video memory, because pull/push instructions can deliver faster throughput than traditional load/stores.

The Atari 2600 has hardware designed to take advantage of such a trick. It has some 1-bit graphical objects that are turned on or off by writing to a certain register. The hot bit of that register is located at bit 1.

Why that, why not the more obvious low or high bit? Because bit 1 corresponds to the location of the 6502's zero flag in the flags register. So you can correctly turn the object on or off with literally just a compare on its coordinate then a push-flags instruction. You'll end up pushing a 1 or 0 to enable or disable the object. No branches or conditionals, and the code is even time-invariant, a helpful property in the tightly cycle-counted world of this machine.

Finally, the video chip registers are laid out with several such objects in succession, so you can continue pushing into several of them without resetting the stack pointer. (This machine has no interrupts, so hijacking the stack pointer into video memory is perfectly safe as long as you never issue a call or other push-pop instruction.)

The machine also aligns some of its read registers the same way. The joystick button is mapped to bit 7 of its input register, so you can read and then immediately branch on the sign flag without a compare instruction.

no with peak power i mean. full sun no cloud the whole day, etc. perfect things wheater for solar energy.
However this barely (never) happens.
so the energy of the panel changes throughout the day. however highest (possible) peak of solar could definitly be higher than a nuclear power plant (anywhere in the world) on an equal amount of land.

nothing to do with today. just a "what would happen on a perfect day". peak vs peak.
also peak of a nuclear power plant could be raised by human and solar panel peak is barely measurable, since there are a hugh amount of factors that could change it.

Yes, you did:

A:
There is plenty of dark fibre around in Australia (driven by a need to bypass monopoloy Telcos)

B:
the bandwidth costs cited by Cloudflare have no real effect on datacenter design

and

C:
(The 'true' cost of transit in AU, ignoring Telstra is closer to the Asia region average of $30 IIRC)

Based on simple sentential logic, you are saying A->B and we're provided with C as additional information. Unless your word that isn't being used as an implicative connective, which would be silly.

How does fallow, unused, dark fibre have any effect on transit cost? Is there a 'transit cost' options market or something?
This is where John D Clark's book "Ignition!" really shines: it's the history of the science of rocket fuel as problem solving. Plenty of candidates on paper, need to be tested for detonation, hypergolicity, ease of ignition, handling, effect on plumbing etc. Red fuming nitric acid is a good example: great oxidiser, doesn't need cryogenics but is liquid even in arctic temperatures. Only problem is it eats through the tanks, until they discovered that adding a small quantity of HF made it OK to store in stainless steel.

I suspect that he would have taken one look at handling radioactive corrosive liquid at 600C and asked to go back to the nice safe rocket lab with only a few explosions.
