I am trying to picture in my head how a romantic evening with this product might develop, and I don't see a way of it not being the most awkward experience for everybody involved.

— Sorry, I was not prepared for this date, we'll have to wait for one hour until the bike messenger arrives with our vegan condoms.

— A guy on a bike will bring condoms here???

— Yes, it is this brilliant new service where they send a condom to Africa every time we have sex.
So in the near future, instead of "no animals were harmed during production of this video" we'll have vegan movies? :).

In a way, maybe it's good that we have one word for the concept.
My wife was listening to Dale Carnegie's "How to Win Friends and Influence People," a book written in 1936 aimed at sales and business people. One thing that struck me was a chapter where he talks about empathizing with people. He gives the example of Al Capone. If we had been born with Al Cappne's body and mind and his circumstances, we would have been him. Therefore, people deserve very little credit for what they've accomplished and conversely very little discredit for what they've not. He ends the section with the saying "there but for the grace of God go I."

It's interesting because the intended audience of the book was not social progressives. It seems like a concept that wouldn't have been controversial at the time. It rings very differently in today's culture, where we like to talk about choices more than circumstances.
If it can be done through charity, why hasn't it?

People have shown time and again that it does take action through central authority to enact societal change because people will not "change [their] allocation of charitable donations" accordingly or have an allocation of charitable donations at all.

Societal progress in the face of injustice takes action from society as a whole.

Fortunately, "no I don't want to give back to the society I take from" doesn't fly with the IRS.
You may be a good candidate for an Australian visa. Not sure where it goes, but this form allows you to register your interest in becoming a skilled migrant.

Also, there _may_ be nothing stopping you from living in the US but working remotely for a company in another country. That may be a good path to getting an Australian/European/other company to sponsor you for skilled migration.

Best of luck!
Bin Packing Problem: Two Approximation Algorithms
I shudder to think of living a life where I would have to employ weapons like these.
Porting Plan 9 to compile with GCC and Clang, or giving it a POSIX compatibility layer seems like missing the point; Plan 9 was notable because of all the stuff it threw out despite being familiar and widely admired, from text-only output all the way down to ANSI C.

It's an environment that demands you adapt to it, rather than vice versa. POSIX doesn't need another quirky API bolted on the side, it's already got quite enough as it is.

Here's a potential sort of loop hole. Set up a software development business back in your home country (or another country, non US). It doesn't have to be much - maybe a bank account and a couple of your developer friends as would be contractors for it.

Then in the US you can legitimately use your "Business Visitor Visas (B-1) - ... to consult with
business associates, ... or negotiate a
contract"

http://travel.state.gov/content/dam/visas/VisaFlyer_March_20...

So you can chat to startups and offer to get stuff written for them by your company abroad. They can legally pay your company and your company can pay you a salary while traveling.

I think all the above is legal. Not really legal but very hard to catch is you could actually write some of the code yourself in your room or a cafe in California if the friends back home don't do it. If immigration get on to you it would be hard to prove you are working rather than just mucking about on the laptop. On the other hand if you are in a work situation in an office then they will assume you are working illegally.

The above has an advantage that if you do well it may actually turn into a real business.

There are many classically equivalent formulations of the axiom of choice, the one I gave is just the one I like best. :)

But you are right, the devil is in the details, so let me spell it out precisely:

The axiom states that for every set X, there is a function

\epsilon : P(X)/{\empty} -> X

If you want to restrict yourself to first-order logic, then you have to encode the function \epsilon (e.g. as a functional relation, where relations are in turn encoded as sets of ordered pairs, which are in turn encoded with Kuratowsky's construction). Set theorists like first-order logic and this encoding overhead is the reason why it's not the standard definition, even though it's arguably what the axiom is trying to express(1,2). Apart from that the statements are (classically) equivalent:

To go from the higher-order version to the cartesian product, note that the cartesian product of an I-indexed family of sets is a set of functions f from I to the union of all X_i's, such that f(i) \in X_i for all i. Let (X_i)_{i\in I} be an I-indexed family of sets, all of which are non-empty, then (i -> \epsilon(X_i)) is in the cartesian product of the X_i's, where we use \epsilon for the union of all X_i's. The reason we couldn't build that element without AC is precisely that we have no way of selecting exacly one element from each X_i, even though we know that they are non-empty.

In the other direction we can use Zermelo's well-ordering theorem to construct a well-order on X. We define \epsilon to pick out the minimum with respect to this order.

(1) This really is what the axiom of choice was meant to express. If you can read German, you can refer to Zermelo's own work:

https://eudml.org/doc/158167

Under point 2 in this paper, Zermelo assumes that there is such a choice function on a given set and from this he derives the well-ordering of that set.

(2) Another example of the drawbacks of working with a first-order axiomatization is the axiom of regularity. The idea we want to express is that there are no infinitely descending element chains ("every set is well-founded"), but expressing this in first-order logic leads to a convoluted statement which obscures the simple idea... and is also not a correct encoding of this idea in intuitionistic logic!
Hi, thank you very much for your answers.

Part of my questions were piqued by this blog post (https://blog.ethereum.org/2015/08/07/on-public-and-private-b...) which defined a private blockchain as a "blockchain where write permissions are kept centralized to one organization". I think that it might be the case of people piggy backing on the buzzword and that people are using blockchain as a sort of computerized ledger.

So, generally speaking, a coin with a larger number of loyal miners will be more resilient than another with less loyal miners?

I think I made a mistake with the rising transaction costs - in USD they have risen with the price of BTC but have been rebased a few times.
As of 10:29:33 UTC, everything is back to normal as far as I can measure.
It seems like a science writer's scheme to tie theoretical physics to what "the informed reader" may have familiarity or interest in, ie. DNA, putting Schrodinger and Crick in the same orbit.

Technically speaking, molecular interactions must rely on quantum effects, therefor the encoding does exist at the quantum level, as opposed to the applesauce level.

But this article is not really about genetics or applesauce.
It seems to have come back now for me. Could someone else confirm the same ?

> Since people willing to donate have no real vision of people who are in need,

They usually do, it fits their vision of what a "worthy" recipient of benefits looks like. Relying on charity to provide social services would mean a significant portion of people would be cut out from receiving them, either due to policy or the lack of donations.
> Also, at the risk of being controversial: the clip is less valuable if you already know more about magnetism than he explains in the video, and if you're already familiar with the regressive argument.

I can't see any possible way in which that statement would be controversial. That you felt you had to couch such a statement in a preemptive defense says a lot about how little time many folks take to think before criticising. :(

> [P]erhaps I'm just biased because I see these clips getting reposted [often so they lose their] magic eventually.

True. I know of very few things that retain their magic after being replayed for the billionth time.

> While he does give an answer at around 5:30, it's a pretty small part of the response.

But he does give a good answer to the question. Your statement indicated that you held the opinion that he never answered the question, choosing instead to deflect the original question and answer another, unrelated one of his choosing.

Given that the tone of the thread is "At least one person thinks that Feynman is being a condescending jerk.", you might see why I thought that a statement that supported that conclusion but was based on a basic misunderstanding of the material warranted a clarifying response.

The most common thing that comes to mind is altering huge database tables. You may need from minutes to hours to perform heavy SQL operations and if you run your commands from a client you want it to survive the ssh session, no matter what.
Another example is the import/export of large quantities of data (e.g. to clone/move a machine) or perform a long running task (e.g. you found a better way to compress images and want to run it once on every image).
Of course these are not everyday tasks, but once in a while they may be required.
That said, if you connect via ssh to a server you are rarely happy to "lose" whatever task you have run, there aren't major drawbacks in using screen/tmux everytime you connect to a remote server.

This seems excessively nit picky. Is the 'heat treatment' technically part of the forging? Technically no but for the layman's idea of forging it probably is ok to say yes.

Did that one line in the article perpetuate the trope? In the sense that it means 'merely wielding a katana makes one a superhuman fighter' I would say 'clearly no' but in the sense of 'katana is the coolest sword' perhaps. Did katanas have world renowned sharpness? I would say yes. World renowned 'strongness' (which can have a lot more meanings)? Notsomuch.
"So I downvoted the comment mostly because it was dismissive of the entire article"

- I thought that was an issue of tone.

I don't think it was dismissed because it doesn't bust the 'Katanas Are Just Better' trope, but because it actively perpetuates it.

> Also is the article even wrong?

- I think so, but I'm far from an expert. The quote says that the Katana's sharpness and strength were unique among swords, when in reality the picture seems to be far from clear-cut. Strength in particular involves some degree of flexibility, which Katanas did not tend to have (I think). The quote also says that a katana derived its strength and sharpness from the folding process - I think the article you link doesn't say anything about that. It says that it has a very sharp edge, and further that a curved edge is better than a straight edge for slashing.

FWIW I really enjoyed the original article, there seem to be some interesting parallels between how polearms in Europe and these chain weapons and thrown weapons in Japan developed from ordinary tools, and in such different directions (in some cases). I also think that tone might be a good reason to downvote a comment, I just thought the topic that the comment was hinting at could be quite interesting.
Yes, I noticed things getting better around 3:30 AM Pacific.
Right, I also do work in embedded (without OS), so I'm familiar with the limitations. However, there are situations where it's tempting to write a very primitive JIT or at least glue pieces of code together in a buffer and execute it, to get good inner loop performance by making it as few instructions as possible.

So far C has been enough. Achieving low (=preferably none) defect rate using C is challenging enough.

Usually FPGAs can take care of performance critical part. They do increase total cost, though.

Nobody is suggesting that someone living under a bridge should start investing. But there's a vast spectrum of people between that and the 1% who can invest. I did say 'start', implying that one would regularly add more funds over time.

Oh that first answer is very interesting - my thoughts at the moment is when/if is this technology going to be included by governments alongside their currencies. Eg each currency being "digitised" alongside standard paper currency. Doing some background reading, this reads as the opposite of the goal of bitcoin/blockchains.

I feel as if a more achievable goal would be not to have a blockchain as a currency or reserve currency, but rather a settlement mechanism shared between banks and individuals (who don't have direct access to ACH etc). That means the coin would be the vehicle of transmission and record. Is this a common viewpoint?

> You seem to be blissfully unaware that they're in fact the same researchers: André Seznec is a co-author of the paper.

He's the third signer of the current paper but the first of the 2006 one. It's the case of legitimizing the "research" which only confirms exactly what Intel recently implemented in a given CPU generation, even if the grant is for other goals ("ground-breaking, high-risk projects"). Or, to be clearer, I respect the deeds not the persons.

I fully understand the need for Seznec to be able to claim that the algorithm is really used by Intel and that therefore he co-authored the last paper. But confirming that Intel used ITTAGE is "ground-breaking, high-risk"? No. And does that mean we should never use goto label in the tight loops? No.
Our intuition is so poor that it even gets many classical mechanics problems wrong. Most hilariously the various resonance-related things (my favourite practical example is a pendulum swinging upwards, which looks like pure magic).

Intuition is also very poor in dealing with nonlinear things (think soliton waves and all that stuff). So, trusting an intuition is always wrong and intuition got no place in science anyway, not just in nanoscale.

Competition sports I find a complete turnoff --- as soon as I find myself facing off against anyone else I instantly lose interest. (It comes from very bad experiences of mandatory exercise at school which basically taught me that I always lose.) I've tried weight training --- spent six weeks doing ~45 a day when my local gym had a special offer. That was even more ghastly; I'd find myself watching the clock desperately wanting it to be over.

The point I'm making is that exercise is not fun for me, and while I appreciate the effort, attempts to persuade me otherwise are doomed to failure. (The endless, banal music the gym played didn't help.) What was worse was that there was no objective way to measure progress so I didn't even know if it was doing anything.

(That said, I do enjoy hill walking (== hiking), but that's even more of a time sink and not something I can do on a daily basis. It's also strictly low-output aerobic.)

Tex is incorrect or misquoted, a 1G barrel roll is next to impossible. More than 1G must generally be pulled at the entry point if you're even going to make the first loop. Even aerobatic champions in Su-26s struggle to do it, and those things have ridiculous power-to-weight.

Furthermore, if you were watching a barrel roll you'd see the aeroplane's nose turn towards you as an observer. That'd didn't occur.

What did Tex call it? The exact words out of his mouth:

"So I came across and did a chandelle"

All we know is he hacked something on the day, and it worked.
