Once I understood this, I find it is a bit a cheat (as you might expect). The 'cuts' are not cuts in any real-world sense.

Hopefully you are happy with the idea that there are as many integers as there are both even integers or odd integers. Therefore in some sense I can "cut" the integers into two equally sized sets. This paradox does something very similar on the real numbers, making use of the form of the real numbers to avoid the "doubling" effect I got when cutting the integers.
We did something similar at Facebook for iOS and OSX automated testing and a few of them doing iOS app builds.

Here is a post that Jay Parikh (VP of Infrastructure) made about it.

Do you regard the subjective experience of being concious as a something that can be adequately described by detailing neurological processes? As in, I know you might argue that a specific combination of atoms will correspond to a specific mental state. That doesn't really tell you anything about the subjective experience of being in that mental state though.
There are some recent federal cases (Weev http://www.wired.com/opinion/2012/11/att-ipad-hacker-when-em..., Aaron Swartzhttp://www.wired.com/threatlevel/2012/09/aaron-swartz-felony..., and a prosecution of scalpers http://www.wired.com/threatlevel/2010/07/ticketmaster/) that view scraping as a felony hacking offense. The feds think that an attempt to evade CAPTCHAS, IP and MAC blocks is a felony worthy of years in prison.

In fact, the feds might think that clearing your cookies or switching browsers to get another 10 free articles from the NYTimes is also felony hacking.

Which is to say, be careful what you admit to in this forum AND how you characterize what you are doing in your private conversations and e-mails.

Weev now faces a decade or more in prison because he drummed up publicity by sending emails to journalists that used the verb "stole".
Sigh.

SGI had this in Ultrix in 1991-1992ish (maybe earlier).

Why? Their market was graphics. If anything non-essential prevented the system from rendering a frame, an attempt was made to run that on another processor.

I remember a 4 processor reality engine^2 that had four processors. 1 processor was dedicated to graphics. another to networking. I don't recall what the other 2 were for.
Agreed! But most everything I write about will be in the past. I'm a slow learner.

I figure my current experiences are not very valuable to others. It's only valuable once I've learned something sharable from it, and that usually only happens in hindsight.
I think the point is that both situations are worse for the customer. The regulations which supposedly protect the customer (like cabs being required to take any fare) aren't followed, but the regulations that harm the customer (like trying to ban Uber and other competitors) are followed.
Wikipedia says you can collapse two balls into one, so doesn't that mean you can cut your ball in half, mold the halves into balls, and then merge those two half-volume balls into one half-volume ball? And if you can do that, can't you get to an infinitely small ball?
Um, what? You'll dissipate more heat at 110v than 220v (high school physics -- heat dissipation is proportional to resistance and the square of current, so for a given wattage, it is inversely proportional to voltage — hence high voltage power transmission).

In any event, 220v is no big deal. It's household current almost everywhere except the US. (A few countries use 110V, Australia is supposedly 240v.)
I know US passport control is strict but never heard of the UK being so strict. Unlucky to get a grumpy woman with a chip on her shoulder.
Wow that is ignorant.
It's economics: when it's raining, cabs will pass on a long-haul fare in order to pick up half a dozen or more short-hauls in the same 60-90 minutes. Especially in Manhattan, a cab in the rain will never be empty, so they're guaranteed fares and tips that will add up to more than the fare + $5 or whatever the average airport tip is.

I don't see this as so very different from Uber raising prices in response to demand.

As others have pointed out: get in the cab first next time to avoid disappointment. And don't ask, tell the driver where you're going.
> Even if the resistivity values of the copper and solder are similar (I'm pretty sure they're at least in the same order of magnitude), you'll still end up with the same amount of current running through the copper wire and the solder.

And what's the problem with that? The resistance of the solder will be minimal (as you say yourself, pretty much equivalent to copper), so the voltage drop and heat production should both be low? Am I missing something?

I mean, I'm pretty sure there's solder connecting the copper wire to the PCB of any PSU in my house, all running at 230V.
Yeah, being too honest and excited to see London was her mistake.
Yep. You're right. It was supposed to be a light-hearted and fun point, delivered with a smile. I guess that didn't come across. My fault, again. :-)

As I understand it, the Banach-Tarski construction depends on the axiom of choice. And Banach-Tarski violates my intuitions so thoroughly that I think I might prefer to dispense with the axiom of choice than accept B-T.

If you do give up the axiom of choice, is there a lot of cool/useful math that you'd also have to give up?

A lot of this information might already be available, just not in the obvious places. An example:

"how to start an airline" came up a couple of times in this discussion. If you ask an existing airline "How should I begin?", they might see you as a future competitor or as a waste of time - either way, they won't gain anything by helping you.

But plane manufactures do gain something from helping you. Even if only every millionth guy looking for advice actually buys a plane, it's still worth it for them. In face, you can check out Boings guide on how to start an airline:

I'd wager that it's the same in other industries. If you want to start a cable company, talk to the people that'd profit off of it - people selling routers, contractors that build the infrastructure, helpline operators, etc.

Starting a wiki is a great idea, and there's already some information you could copy/link to (depending on the license). You'd have some information right off the start.
Arbitrarily small, yes, but never zero. You will always have c points, where c is the cardinality of the continuum.
This seems fantastic, makes me wish I had an iPad. I love the option for side by side web browser and code (especially in landscape).

It is equivalent to, for instance, "every vector space has a basis", and to Zorn's lemma, which I've often used.
FTA: “He is obsessed with obscurity, which is why I love him,” James Skotchdopole, one of Quentin Tarantino’s producers and a frequent guest,says.

Many of those that entertain being "cool", cultivate an 'underground exclusivity and avoiding the mainstream' image. Of course this helps to create the mystique. I would argue that a genuine desire to be obscure, is perhaps not the main emotional driver, but rather being seen as cool is.

If that were not the case, participating in a New Yorker feature would be an epic obscurity fail.

More excited and naive really. Main reason was a holiday, going along to sing in a small pub was only an added bonus, non paid.
It seems like every time that a startup gets bought and internalized to some proprietary system or network, it opens up the market for another startup in that same exact space.

Here's another vote for Jiro. Not the most exciting movie ever (or even in the top 100) but it's always inspiring to get an inside look at someone who has truly mastered his/her craft. The way Jiro speaks about sushi made me think I'll never really understand anything on that level (but it doesn't hurt to try).
This. I'm all of punishing the hell out of cabbies that cheat (e.g., fare refusals or the out-of-city overcharged fares that were discovered via GPS data), but the failure to get into the cab ruins the whole case.

Get in the cab. State your business. Snap a photo of the driver's license if you are asked to leave and report him/her to 311. Blog to your heart's content on behalf of your company's alternative service.

Is innovation fueled by debauchery?
The weird thing for me is that I'm an atheist, almost sometimes a militant atheist, and yet by far the only people I met doing decent work in Afghanistan were:
1) Afghan expats (generally moderately religious), like doctors from London who had moved back.
2) Christian missionaries, specifically those who had remained in Afghanistan from ~1979-2001 and beyond. To a limited extent, some (religious based) US charities as well.

Totally absent were USG organizations like DOD, USAID; the UN; various NGOs; ISAF; etc. The UN water pumps were helpful, but those I think mainly pre-dated the 2001 conflict, and in no way approach making up for the harm caused by the UNODC drug control policies.

SSF, Fab Lab, the guest house, Tim, etc. all did some worthwhile stuff, but were really an exception. In general, the only people doing anything helpful were locals and religious people.

This was slightly less true in Iraq; there were some limited positive works done by NGOs and by specific military commanders (using their under-$100k local budgets), and some worthwhile projects from CA.
Basically, the article says Atlanta is good because the cost of living is cheaper, there is a lot of smart talent due to the educational institutions, and the city is seeing an increase in both communication and transportation infrastructure.

Downsides mentioned (in comparison to the more popular startup cities) are the lack of startup investment capital, not as many people with an entrepreneurship mentality, both of which lead to a less-active startup culture.

However, I wonder what the effects would be if Atlanta becomes a startup hub on par with NY or San Francisco. I rather like the fact that it's cheaper to live in Atlanta than most big cities.

An increase of capital to the local economy would result in rise in the cost of living, which (I believe) is one of oft-cited reasons for moving there. A 3 bedroom townhouse in a very nice residential area for ~$150k isnt unheard of.
Israel Hinders Solutions, Remember the USS Liberty: Israel Cannot Be Trusted
U.S. criticism of the U.N. elevating Palestine’s status was wrong. Americans should not trust the dangerous relationship the U.S. has with Israel. The Israeli attack on the USS Liberty is historic testament on just how dangerous that can be.
Agreed. He should provide a graphical solution to every example given. It's distressing that none are given, not even then ignore-exception piece. That's the brilliance of Bret Victor's essays: he posits the idea, bringing you along in the 'yeah, that's been bugging me, too' fashion, and then proceeds to guide you through working solutions that build on themselves over the course of the piece. If you've been properly dog-fooding, show us the crumbs and the empty bowl to prove it.

Graphical wrappers to plain text are not only 'orders of magnitude harder [to implement]', but that much harder to debug as well. If your GUI client to a remote server beach-balls waiting for a command to complete, is your code wrong, or your connection latent, or your desktop app crashing? An SSH connection to the CLI server can cut through a lot of that pretty quick.
Austin seems to be doing alright.
That there's no profit is something I've seen repeatedly, including written by Warren Buffet. So my question is where does the capital they burn through each year come from ? What kind of magic business is this where companies are eternally taking losses yet still around ?

Is someone giving them money to burn ?
As in, the difference between the neurological processes that govern ones mental state, and the subjective experience of having that mental state.

For example, if I'm hungry and eat a good meal the changes in my brain chemistry that induce the sense of well being that follows are well understood.

That doesn't tell me anything at all about the actual subjective experience of feeling pleasure though. That is something distinct.
I think Atlanta has much to recommend in terms of a startup destination: great access to smart engineers (Georgia Tech is in the city, Duke and UNC are not too far away), low cost of living, quite livable, etc.

However, it's just so tremendously isolated. The closest real city with a real financial/tech sector is Charlotte, but the transit interconnection between the two is very weak and as a result there is very little cultural cross-pollination between the two cities (unlike say DC and New York which are about the same distance apart).

I think Philadelphia is actually a smarter bet. Low cost of living, like Atlanta, Penn and Drexel right in the city, and just 90 minutes on the train to either New York or DC. The amount of cross-pollination in the DC-PHL-NYC corridor is just phenomenal, enhanced by the fact that the three cities have very different cultures and host very different types of industries.
It says that the product of non-empty sets is always non-empty. Do you really want to give that up?
The argument here seems to be "Opportunities lie in the places others overlook." But that seems to be a little off-kilter, in this case: Atlanta might be a good location for you if you're hoping to start a business that would be heavily in the pockets of shipping companies or airlines. But if you need to have access to innovators, then you either need to bring innovators to you (Manhattan project style), or you need to go where innovators want to live. I know a lot of companies use cost of living in order to try to entice people away, but at a certain point, and for the right kind of person, salary and cost of living are not the strongest pulls. Rather, innovators thrive when they're surrounded by other innovators. This also seems to be why innovative companies tend to cluster together: this is why Paris, once it reached a certain level of cultural cache, was able to continue attracting the best authors and theorists. And why it's hard to see a better place in the US to attract the top talent than New York and San Francisco (or, for academics, Boston). Because that's where their talented, intellectual friends are headed.
Ternary sentiment detection rates are currently around 30-40% for Spanish. English rates might be better, but not by a lot. That means you give a piece of text to your classifier and it will tell you correctly if has positive, negative or neutral connotation at most 40% of the time.

In short, we are still worse than a fair coin toss at sentiment detection.

Language is not tricky at all, no sir. Can you see why? :-)
Same boat as you. Never had any close calls before though, went to Ireland recently via Heathrow and had no problem, gave the exact same info. All seems to be down to the officer in charge and the mood they are in. Show up early and dress well for a chance to get bumped up.
I recently spoke with someone who was accepted to the S12 batch without an idea. He's currently pivoted from what he was working on during that session, but is about to launch a new product. Sorry to be vague on the details, but I feel that if he wanted people to know what he was up to, then he would post here himself.
Emory University is also in Atlanta. Definitely some smart people there.
Pretty nuts, entrapment style.
Oh no, they are not merely too busy. In most cases, the industry actively wants to exclude others and keep their info to themselves. When I worked at a Fortune 500 company, running my mouth on the internet about the industry could have gotten me fired. I say more these days, now that it is relatively safe. I still don't name the company, just the general industry.
As documented in Mike Grynbaum's NY Times article, the five taxis probably weren't lying about the shift change.

http://www.nytimes.com/2011/01/12/nyregion/12taxi.html

It seems irrational at first, but changing shifts at the same time makes drivers and cars more interchangeable. More importantly, it makes day-shift vs. night-shift approximately equal in profit opportunity. It's a shame the shift changes coincide with after-work rush hour and a popular time for night life to wind down.
An interesting wrinkle in these "column" keyboards (where Q-A-Z are lined up in a column rather than staggered) is that I self-corrected for this deficiency years ago; my left pinky hits Q-A-Shift, ring finger hits W-S-Z, middle hits E-D-X etc.

The W-S-Z fingering leads to a nice curve that mostly follows the movement of your finger, just like what you get on the right side of the keyboard (U-J-M, etc).

I don't know how folks type Q-A-Z with their little finger. It causes immediate hand pain to curl my fingers inward/perpendicular to hit Z, X, C, and V.

I imagine this method was only taught in the first place thanks to clueless typing teachers who thought "first keys on the left = first left finger", ergonomics be damned. Does anyone else type "Z" with their ring finger?

When we first started rolling out our addresses (2004) - it looked very much like any address space we requested, would be locked to the ISP that we were connected to. Many of our nodes we run for large utilities, and we wanted to have the flexibility to hand them over to the other organizations without any paperwork. RFC 4193 let's us carve out /48s at will, assigning a /48 per customer, that is in no-way connected to any ISP.

Also, and I recognize this is a very unpopular perspective among some, so apologies in advance, we don't want anybody on the Internet to know what our internal addresses are. And we also want to eliminate any possibility of direct routing from the internet. Going with RFC 4193 (AKA ULA, AKA IPv6's answer to RFC 1918) allows us to carve out an address space that, even if it did somehow become known to the internet - wouldn't do them a lot of good, because they can't route to it.

A lot of people think that renumbering is as simple as plugging in a new address to be advertised off the router - but what they forget is the huge number of places in which those IPv6 addresses (and networks) have been plumbed into other router configurations (RFC 2893 6in4 tunnel configurations) - not to mention all of the network diagrams, and databases. RFC4193 means that we don't have to worry about renumbering, and, if we chose to hand it off to a third party, their is a probabilistically insignificant chance that they are using that space, so merging is trivial.

Was about to write the same thing. Taxi drivers aren't stupid and they weren't "fail[ing] to respect" the author, they want to maximize their earnings, they also want to get their cars back before the set shift change; if they're late they have to pay a fine (http://www.nytimes.com/2011/01/12/nyregion/12taxi.html?_r=0).

The advice people are giving to just jump in the cab applies in the case where the driver's off-duty light is not on, but the rider looks like they're going to some part of Brooklyn (or wherever) that the driver doesn't want to go, and the driver is wrongly being selective. The situation of having to just jump in the car has never come up for me in Manhattan with an on-duty car, it has before in Brooklyn though.
Funny, that's how pretty much everyone else feels about visual programming.

Except the UNIX way of things runs the Internet, and visual programming tools run practically nothing of relevance at all.
We're using RFC 4193 space, which doesn't route globally, so we need to have a globally routable IP address if (and when) we decide to route onto the internet. NAT6/PAT6 does that for us. For numerous reasons, (see a prior comment by me) we don't have a lot of interest in putting globally routable addresses on internal hosts.
Same here. I've only really noticed it recently too.
I doubt the small increase in capital from bringing in more startups would have a large effect on cost of living.
Hilbert's basis theorem is the big one, and the reason the axiom was invented. But you can get very far without it - you just have to be very careful about it, because the operation of choosing an arbitrary representative of each of many sets is so natural it can be hard to realize you've used the axiom.

Having just moved after 6 years in Philadelphia: very high violent crime, and corrupt local government w/ no interest in technology; rents are lower compared to DC or NYC but raising rapidly. While I loved going to the Philly tech meetups, most everyone was working in the suburbs, where companies are free of the high city corporate tax rate (most cities don't _have_ corporate taxes).
Even in the case you describe, they will try to refuse or claim they don't know the way most of the time. If you still hold your ground, you better know the route because if you don't you can expect the cabbie to get "lost" for an hour and have you pay for the privilege.
Believe me it would take a lot of startups to even make a dent in the amount of available housing at bargain price.

I would be more concerned by the fact that traffic is a nightmare and there is not much hope the state of georgia would ever get their act together and build even a half decent transit infrastructure.
