There seems to be a bug here. Suppose that in a puzzle there is only one 8 and one 9 that do not overlap in any way (row, column, or 3x3 square). Now, suppose that Peggy comes up with a false solution to the problem which sets both of these tiles to 8. Then, neither the 8 nor the 9 is allowed to be picked for the green squares, and so no test of Victor's can disprove Peggy's false solution.

Edit: this seems easily fixable too: rather than the whole green tiles thing, just allow Victor to query either a row/column/3x3 to prove the solution is a valid sudoku, or query the original filled in tiles, to show that the solution corresponds to the original problem.

What do you mean, "in numbers"? As I pointed out elsewhere, the number of distinct customers is irrelevant; the number of chips sold is relevant, and I do not believe gamers buy more chips than compute farms.
I don't buy it.

Something I learned in grad school is that there is a continent of linear problems surrounded by exactly solvable islands in a vast unsolvable sea.

For instance, you can solve quadratic equations easily with a closed form formula, and do cubics and quartics with just a little more work, but there is no closed form for quintics and higher and no amount of "intelligence" is going to change that.

Similarly, without the right experimental results, no amount of "intelligence" is going to lead to a fundamental breakthrough in theoretical physics.

You might be able to throw more speed, more computing units, a larger memory, etc. at a problem but that doesn't mean you're going to get proportionally better results.

She mentioned something about signing something and not realizing it at the time, though.

That will do it. That "something" was probably an agreement to co-sign the loan, and thus making it her sole responsibility if the other party fails to pay.
I'd just like to remind people that at the beginning of the 20th century many were predicting the doom of Mankind once we would reach one billion folks. Needless to say it did not happen and we went much further than one billion and took care of starvation along the way. Of course there are many reasons for this, but let's not underestimate the resources of mankind to solve its problems.
I think you are right. When I was living in Melbourne, it just felt like the most folks lived/worked in the one city, and if there are any travel, it was the car. Also felt like the majority of air traffic was between Sydney and Melbourne. I guess times have changed since I lived there.

What does this consist of? Is it an open source project? I would love to set up something like this, but I constantly find myself not having the time.
The freedom to modify should be compared to the freedom to ask anyone to repair it. You may not be personally capable of modifying the software to suit your needs, but if the software is free, you can hire anyone to do it for you without having to beg the original author to do so for you.

Only now is this argument starting to come to other things such as cars and farm equipment as they get ever more software in them. People are finally starting to want this freedom to modify but phrase it as right to repair.
> I agree, open source solutions can sometimes have the same level of 'lock in' as closed-source enterprise solutions.

Not at all. You can always hire someone to update an abandoned software you rely on or help you migrate to another alternative. Lock in would mean you have no such option.

> Most OSS software has a certain degree of 'evil' behind it (particularly as they get older and the community becomes increasingly financially-motivated).

There is nothing wrong in demanding payment. My time certainly isn't free and I will not write code for free unless it solves a problem I also have.

> I still think that OSS is better than enterprise software most of the time.

This distinction doesn't make sense. Until recently I worked for Canonical on MAAS, a physical hardware provisioning tool for data center operations. It's free (AGPL) and you don't get much more enterprise than managing hundreds of servers.

We have to be very precise with the terms we use. There is enough material here to fuel a flame war that'd outlast most stars.

State Department policy on Syria is regime change going back to at least 2011. The method/means is still fluid.

See the article and State Department testimony below, emphasis mine.

NYT, from 2013:

"Last summer, as the fighting in Syria raged and questions about the United States’ inaction grew, Secretary of State Hillary Rodham Clinton conferred privately with David H. Petraeus, the director of the C.I.A. The two officials were joining forces on a plan to arm the Syrian resistance.

The idea was to vet the rebel groups and train fighters, who would be supplied with weapons. The plan had risks, but it also offered the potential reward of creating Syrian allies with whom the United States could work, both during the conflict and ___after President Bashar al-Assad’s eventual removal___.

Mrs. Clinton and Mr. Petraeus presented the proposal to the White House, according to administration officials. But with the White House worried about the risks, and with President Obama in the midst of a re-election bid, they were rebuffed."

http://www.nytimes.com/2013/02/03/us/politics/in-behind-scen...

From 2011, testimony by Jeffrey Feltman, Assistant Secretary of State for Near Eastern Affairs, State Department:

"But we take the advent of the [Syrian National Council] very seriously, and we support the broader opposition’s efforts to focus on the critical task of expanding and consolidating its base of support within Syria by articulating a clear and common vision and ___developing a concrete and credible post-Assad transition plan.___"

> about 14 percent of U.S. households have a credit card balance of more than $10,000

That's amazing, but not surprising. I used to have some neighbors who started shopping for a house. Everything was going well - they had found a home they liked and had gone to apply for a mortgage. Which is when it was revealed that one of them had a couple of credit cards the other didn't know about - with a $14k balance on them.

People debate over the best method to pay them off and get out of credit card debt, and it just doesn't matter as long as you get started. Once you get into the habit of watching the balances decline, then you can optimize by doing things like paying the higher-rate ones first, or paying off the smallest balance one first, whichever works for you.
Learning How to Teach a (Technical) Class
There was an old video game store blog that had a story on the game tournaments that were played at the store. The owner gave 1st and 3rd good prizes (game, joystick, etc.), but gave the second place person a can of pop to remind them they were "1st loser". Cannot remember the name of that thing.
Literally me right now. Of course, as someone who lives in Australia, where our government-run student loan scheme is both income-contingent and deducted straight from payroll as part of income taxation, the only time I notice how much I owe in student debt is once a year when I'm doing my tax return... other than that, I don't worry about my student debt at all, knowing that even if I lose my job it's not going to drive me broke.
The number of gamers who upgrade yearly is fairly small, and the number who upgrade their base platform (CPU + mobo) yearly is even smaller. I would be very surprised if there were more than a million in the latter category.

As for datacenters and compute farms, the large ones are upgrading portions of their systems yearly, if not expanding on top of that.

I think you're confusing economic differences between the US South (very not-catholic) vs Northeast (very catholic) as being caused by the religion when there are a bunch of much more important differences, economically speaking, you could look at.

Take a look at total GDP per capita, the northeast is way ahead. Different metric, different results, still not caused by religion.
"The Federal Communications Commission regulates interstate and international communications by radio, television, wire, satellite, and cable in all 50 states, the District of Columbia and U.S. territories. An independent U.S. government agency overseen by Congress, the commission is the United States' primary authority for communications laws, regulation and technological innovation."

Exactly what part of that means the FCC has no place in regulating internet access?

> I could see localities getting started by using a wireless mesh with their help

That would be illegal in NC, the law the FCC was challenging explicitly states "it is against the public policy of this State for any unit, department, or agency of the State, or any division or subdivision of a unit, department, or agency of the State to engage directly or indirectly in the sale of goods, wares or merchandise in competition with citizens of the State and Whereas, to protect jobs and to promote investment, it is necessary to ensure that the State does not indirectly subsidize competition with private industry through actions by cities and to ensure that where there is competition between the private sector and the State, directly or through its subdivisions, it exists under a framework that does not discourage private investment and job creation"

The fact that Time Warner wrote the law and got it passed would be hilarious if it wasn't so disgusting.
You can examine the whole issue of productivity growth and wage growth in real terms (that is, taking inflation out of the picture by deflating using some inflation measure, either a GDP deflator or consumer price index or so) instead of in nominal terms.

While the article doesn't explicitly mention it, I'd assume that they're looking at productivity in real, not nominal figures, precisely to disentangle the effects of inflation.

Meaningful comparison across countries requires purchase power parity (PPP) exchange rates, rather than market exchange rates. However, this article doesn't really talk about other countries at all, so I don't understand why you bring up PPP here. If fewer hours of labour are required to buy dinner, that's just real wages, nothing to do with PPP...

And how does lower labour force participation enter? (If we assume that less productive workers drop out first, that should increase productivity, btw - which we don't see...)

In the eyes of supporters of either major party, a vote for a third party is a vote for the other major party. It may not have always been this way, but it has for as long as I've been an engaged voter (~20 years).
Get the laws overturned through the democratic process. It is easier than trying to get the unelected bureaucrats at the FCC to stop doing stupid things like requiring radios use proprietary microcode (this is why ath10k's radios require microcode) or more recently, tightening rules on how people can adjust radio parameters due to a few people who did stupid things. They are the reason why Asus, TP-Link and others were locking down routers and rather than reverse their mistake, they are playing whack a mole trying to coerce companies to not take the easy road in complying with their requirements. It is easier to elect someone else into the local and state governments than to convince the FCC to fix things when it messes up.
But this scenario doesn't apply to the vast, vast majority of folks in the med school situation. These newly minted doctors will make low wages in residency, but they are still great credit risks because they can be expected to make much higher salary in the future withOUT the need to acquire additional debt.

The problem with these "insolvency" calculations is that by going into debt for education you are trading cash for future earning potential. If you valued that future earning potential like an annuity, it many cases it would be worth millions of dollars, but straight net worth calculations value it at 0.

Of course, the problem with student debt is that a lot of folks are making really bad investments on that "annuity" - trading large sums of cash for a minimal if any increase in future earning potential. Despite all the upheaval in medicine, however, almost all doctors can expect to make much, much more income after they finish residency.
Sure they are.

I mean, sure, you and I know the difference between an 8-bit micro with some friendly libraries and a 64-bit ARM SOC running a full OS. But for a lot of stuff they accomplish the exact same thing. So why not compare them by what most people do with them rather than their raw technical specs.
But do words not matter? The word "utopia" has a specific connotation in the minds of many people, and such experiments continue to drive the narrative that humans cannot be happy unless the conditions are bad.

> I'd disagree and say that in overpopulated areas there is a higher rate of depression, obesity and psychological problems than in places with lower populations - but I haven't provided numbers there and neither have you - so both of our arguments are anecdotal.

I'm honestly not sure what you are referring to. Obesity is much higher in the US, by a wide margin, than, say, India, and India is definitely much more populated. I don't know if I really need to provide numbers for that.

The NEET issue could easily have been caused by bleak job prospects.

My point is, the rat experiment and the current situation don't seem to be even remotely related. Our population growth is not the same, and our population growth is very uneven. We have external forces acting to limit how people live still. There are just so many variables not accounted for that trying to find any connections is more dangerous than it is helpful.
> Is energy a fundamentally different economic input? What is the relationship of energy to economic growth?

I am particularly interested in this. My intuition tells me that energy is special because it is the only thing that the laws of physics says cannot be recycled. And that, given enough energy, everything else can be.

Sounds like she may have cosigned on the debt.

The reason lenders ask for cosigners is because the would-be debtor is a poor credit risk. They want someone to go after in the likely event that the person stops servicing the debt.

Never, never cosign someone else’s debt. Yes, here come a million and one what-ifs for this and that goofy situation. Don’t do it.
As I understand it, shady creditors and debt collectors will sometimes contact the deceased's family. They claim you have inherited the debt, or have some moral obligation to make good on their relative's debts, then pressure you to sign paperwork acknowledging that fact. Then they try to collect the money from you instead saying it's your debt, using that same logic and now that paperwork you signed.

It's a deceptive and despicable scam, but I'm not a lawyer and I don't know the legalities of it. I suspect, in most jurisdictions anyway, it's not legally enforceable and she could probably have refused to pay anything and the creditor wouldn't have a leg to stand on.

" I C++ for a living - you may pity me too. Games, you know."

I've had the displeasure of dealing with it myself. So, a little bit. It can give you a bit of extra safety and flexibility with acceptable performance. Side effect, as I noted for ZeroTier, is you forfeit almost all the static analysis, memory-safe compilers, and other goodies for C language. You're in the category that might benefit from experiments with Rust given it's the C++ competitor, but with more safety. Maybe those ridiculous bugs I see in AAA titles will go away without much extra QA. Nah, I'll be unlucky and they'll be algorithmic. ;)

" Why, they could even use some kind of LISP variant..."

That's so 90's. Next you're going to want them to try to round up all the hackers, programmers, and VC's on one discussion forum. Can't expect people to pull that kind of stuff off. Far as LISP, check out PreScheme: static LISP w/ manual, memory management and compiled to C at first. Got mathematically verified during VLISP project. Enhancement of that could do games or startups. (taps head)

Actually, CARP Lisp is doing that with Rust-style safety if I recall. Has active contributors with an OpenGL snippet as demo:

> Because what matters most is ideology, not actual working open systems ...

The problem is that ideology is the only thing which can guarantee actual working open systems in the long term.

Co-operation with proprietary software is much like co-operation with an oppressor: those who co-operate enjoy a short-term advantage, but at the cost of long-term damage to themselves and to their fellows.

The only way to guarantee freedom is to take it, and refuse to let it go.
