It's easy to imagine that eating 1 out of 3 slices of pie is "the same" in a very specific sense as eating 333333... out of 1000000... slices of the same pie (although that would be infinity out of infinity slices, which is meaningless).

What slips people up is that ignoring everything but the total pie consumed (taking the limit) is embedded in the definition of real numbers.

There's an analogous story with rationals: Suppose x1 = 1, y1 = 3, x2 = 2, and y2 = 6. If we plot them, (x1, y1) and (x2, y2) are clearly different points, but x1/y1 "equals" x2/y2 because they lie on the same line through the origin. We decide that we don't need to know about those individual points.
Seems like a nice system. But to get any traction they are going to need to be able to integrate into Blackboard and other CMS.

In Herman Lukoff's autobiography "From Dits to Bits", he describes building a radio where he surface mounted the components to the glass envelope of the vacuum tube. I believe that he constructed it before World War II. Traditional vacuum tube chassis were usually heavy metal assemblies so this was pretty radical.

Unfortunately, once the tube reached operating temperature, his painstakingly hand drawn traces and glued down components delaminated. However, it shows that people were thinking about that sort of thing.

And/or it can deal with that it comes across. A thin package of screws and nuts, e.g. Home Depot sells a line where a huge selection is like $1.83 or $1.18 (e.g. each package will have a certain balanced set of nuts and bolts, or a few screws), and those packages are sufficiently flat I'd expect them to be no obstacle. Bigger stuff it could just push forward, ideally sensing when that was happening and backing up and going another way. The big trick would be the stuff just low enough to get under it, but that would then block it and get stuck.

This is just off the top of my head, and I'm intrinsically not interesting in robots, I'll bet this is a well developed area in it by now.

Depends on your target audience. I wouldn't want to compete with Amazon as a general proposition. But there may be some specific niche that isn't well served by Amazon. For example, there could be some piece of Tarsnap's infrastructure that is irritating/expensive to create but that other companies want to use.

Note, for example, that Dropbox gets "substantial economic value" from running their own hardware. [1] And Tarsnap is in the position to offer a backup-specific white label service that other entrepreneurs might rather pay to use than rebuild.

The Austrian franchiser probably pays a lot for using the Starbucks brand and franchise concept to an offshore company (not in the US) owned by Starbucks, that pays a kickback to another offshore entity owned by the franchiser.

Now all the profit is offshore. Everybody happy, except the Austrian government (who don't get corporate tax because the franchise hardly makes any profit in Austria) and sausage stands (who wonder if they could make more money if they join the Starbucks franchise)
I'm British, a KLM/Air France frequent flyer, and visit the US a lot (so I end up on a lot of Delta code-shares -- flights booked via KLM/AF but operated by Delta).

Delta are the best of the "big three" US carriers in terms of customer service, and considerably better than American or United. On their intercontinental services they <em>try</em> to measure up to their non-US carrier alliance partners. Nevertheless, they're in third place relative to KLM or Air France as far as the passenger experience goes.

Relevant bit: I was on an AF trans-Atlantic flight a couple of years ago when a passenger a couple of rows behind me became unwell, and the passenger at the other side of my center aisle turned out to be a doctor on her way to a conference. Rubbernecking discreetly, I observed the cabin crew prioritizing the sick passenger's wellbeing and fetching the doctor the emergency kit and all the support she needed. Anecdata is not data and all that, but what I saw was what you'd hope to see in such a situation, not the fiasco described in the OP.
I really hope to see a follow-up story of the FAA giving Delta a serious scolding.

> That's only true for signed integers, overflow is defined as wrapping for unsigned integers.

Overflow is an error condition. Unsigned integer addition is defined to wrap around, and does not have this error.

C11 standard says this like:

> A computation involving unsigned operands can never overflow,

> because a result that cannot be represented by the resulting unsigned integer type is

> reduced modulo the number that is one greater than the largest value that can be

> represented by the resulting type.

Seems kind of ironic that the math professor writing this article uses conjecture as evidence for recommendations to what people should be learning instead of actual statistics.

I'll tell you why:

When I was at FreshBooks in 2008/2009 we figured out our Cost Per Acquisition (CPA) and our per-customer Life Time Value (LTV) / Net Present Value (NPV). We were making about 3x on marketing spend over a period of about 2.5 years. Effectively a 55% compounding yearly ROI. Could we wait, sure, but why? Even at credit card levels of interest we were still winning, and if we didn't our competitors would soon figure out the game and they'd gain market share at our expense.
Why do we even tax corporations instead of just the income that its owners receive from the corporation?

At least in California, Good Samaritan laws will protect someone if and only if they are rendering medical aid that is in line with their training. Meaning if you know CPR and attempt to resuscitate someone who has no pulse and they die / have brain failure -> the law will protect you. If you know CPR and try to remove a bullet from someone's brain and they end up in a vegetative states (IANAL but) -> law probably won't protect you.
I don't hear much in the way of loans. Why would anybody loan money to a business that's losing lots of money and has no assets that could be resold?

Convertible debt is much more like equity than a loan. The easy way to think of it is, "The investor will give us some money, but we'll figure out how much of the company they're getting later." Just selling equity early on is a pain, because the valuation is entirely made up. Being able to defer the question until more data is in works out better for everybody.
After what amount of delay does this kick in though, or is it any canceled flight?
Correction: Induction is how we can understand that a property holds for all finite values.

It seems that you object to the commonly accepted meaning of "...".
More likely: what's being optimised are cabin check proceedures between flights, or reporting cases / incidences of use. Possibly also raiding of supplies by parties with access -- cabin crew or cleaners would be highest on my list.

But the point remains: Delta initiated a 17h flight with a lethal head flight attendant and a half-stocked medical kit, and have failed to follow-up on the incident. I'd like to see the FAA's incident report.

"Google’s mission is to organize the world’s information and make it universally accessible and useful."

The universally part has a lot of room to grow, and the useful part changes everyday.

Not having read the book, but based on what you posted, the example is just one of the giant leaps forward and a way they differentiated themselves as a technology and a company. New leaps will present themselves through continuous improvement and reassessing what is useful.

I have to ask again: Why isn't there a better hardware support for overflows on x86? Mainframe CPUs do have an option to raise an exception condition on arithmetic overflow.
You're being dinged for this as I write, but that's an interesting observation and a sign of failure-to-manage-complexity on Delta's part.

Though information-system-related service failures are generally increasing among carriers, if I'm recalling the coverage of Delta's outage correctly.

Still remains a good flag to raise.
Datum point:

With Air France, the breakpoint is making Gold Status in Flying Blue (their frequent flyer scheme). Irregular traveller or Silver or below? If there's a problem with your journey, you own it. Gold and above? If you encounter a hiccup, they own it, and if you show the folks in the business lounge your card they'll go out of their way to fix things for you.

(I was once flying economy on a Delta seat paid for by someone else, and the Delta flight was late enough coming in that I was going to miss my onward connection. But I had Gold Status to fall back on: AF picked up the ball, bumped me a class, and re-routed me on one of their own flights so that I got to my destination, a bit later than planned but the same day, rather than being dumped in Detroit overnight.)
I have relatively little mathematical education and have been seeking to correct that by self-educating over the last year, so I have a certain bias. Nonetheless, I disagree with the key points of this article.

The article asserts that most modern professional jobs requires only "Excel" and 8th grade programming. In my experience, over-reliance on software like Excel rather than a basic competency in numerical programming is a hindrance to economic growth. Spreadsheet-based numerical programming is opaque and ill-suited to interoperation. This leads to subtle errors, duplication of work, difficulty of replication and silo-ing of meaningful results in the private sector, the public sector and academia.

I take the second point that the transferability of critical thinking skills developed by learning mathematics is unproven. Nonetheless, history is flush with anecdotal evidence of this hypothesis, and in the absence of empirical evidence, it seems unwise to reject that hypothesis out of hand.

EDIT: removed an assertion that the article was poorly argued.

So you're saying that "for all positive integers n : property(n)" means that property(k) might not hold for some k that is not a "finite value"?

The only problem is that this not-finite value does not occur among the integers; thus the inductive procession doesn't actually have that value k as its target. It does not lie in its path, so to speak.

Pretty much. Their chances only get worse without intervention whilst waiting for the emergency services to turn up. I was told to expect broken ribs etc - which, apparently, aren't as grave an outcome as death.
Correct. I'm in Amsterdam and bought from amazon.de last night. I'll usually compare with amazon.co.uk for price and occasionally pay more because the supplier won't ship internationally.

There are plenty of Dutch online retailers (e.g. bol.com and coolblue.nl) but their prices are significantly higher (even factoring the slight difference in VAT). Considering we're supposed to be in a "single market", I've never been able to figure out why that is.
In my experience, a surprising number of people with a humanities education simply don't believe in "wrongness", but merely differences of opinion. They regard truth as peculiar abstraction used by mathematicians and hard scientists, not a phenomenon that actually exists. It's hard for someone to admit to being wrong if they don't even believe in the concept.

This seems to be the most appropriate use of this tactic - a short term burst leveraged against strategic action.

It's helpful to be aware of the variety of options available for funding, but they are not created equal, and this carries a disproportionate cost.

You obviously don't hang out with many statisticians, who also don't tend to believe in truth or being right or wrong; to them, they are just making models that can be tested to reliably approximate some observation. There is no pretense at truth, it's just a model.

I was reading about tort reform once and stumbled upon NZ's ACC concept and was staggered by its effectiveness. I suspect its success is due in part to NZ's population size, but any system that ensures all accident related issues are covered AND for the most part renders the civil courts redundant for personal injury claims is pretty phenomenal. I don't have a source for this, but I also remember reading that the ACC is now one of NZ's largest institutional investors with something like $30bn under management!

This is one of the main reasons I did not migrate to LO.
Or this is a establishment politician with a weak hold on power who has not necessarily got his facts right, or if he's talking about absolute numbers vs. rates is probably lying through his teeth, but knows bashing foreign companies is a crowd pleaser.

And maybe they overtax those sausage stalls, lots of/most every? country has tax regimes with lots of insanity. Apple wouldn't be playing the games it plays with the US if we didn't have the 2nd highest or so corporate tax rate in the world (e.g. see https://en.wikipedia.org/wiki/List_of_countries_by_tax_rates when you factor in state tax rates only Cameroon is perhaps higher).

While I was doing the search for that, I noted that as a region Europe has the lowest, but that's no doubt not accounting for VATs, which the US is allergic to, at least unless one of the big other categories of taxes is totally killed off (like, with a "this time we mean it" Constitutional amendment).

Anyway, my point is that all this results in all sorts of distortions. For example, when the Reagan individual tax rate cuts kicked in, I noticed my parent's business and investing strategies change as tax avoidance became much less important. In his working lifetime, the top rates went from 91% ("We Like Ike???") to 70% (which as I recall was split between 50% or more for "earned" and 70% or more for "unearned" (investment) income), to 38.5%, to 28%, before it started going up again (even the George W Bush tax rate cuts only dropped them 4.6% to 35%).

And going back to the distortions, the family exemptions allowed a normal family prior to JFK's 1964 supply side rate cuts to survive with the lowest bracket being 20%; those weren't adjusted for inflation until Reagan's reforms, which turned them into a pretty minor thing with how inflation savaged the dollar during that long period (the CPI peaked at like 13-14% around the time Reagan entered the Oval Office).
Not that it matters now, but I appreciate you doing that in the face of indifference or outright criticism. If it were me or my family in need, you stepping up would be huge.
This seems to be the key paragraph:

"Most beginners who die appear to be making variations of the exact same error, according to Webb. “They jump off a cliff, get flying, and for some reason there's just this human reaction to try to hug the air like a big, gigantic beach ball,” he explains. “By hugging air you feel as if you're creating or catching more lift than you actually are. What ends up happening is your suit can only grab so much air, and it starts to stall. When it starts to stall, it loses lift, starts to drag, and then, splat."
Ventricular fibrilation, (vfib) "an electrical disorder of the heart", is among the most survivable conditions, if there's a defibrilator available which can be applied within five minutes.

The problem is entirely within the heart's signalling, it's not a blockage, obstruction, aneurism, or other blood-vessel defect. And the treatment isn't counterindicated for most other possible similar conditions.

Short answer: rapid appropriate response can result in total recovery, but it's very dependent on the underlying etiology.
