I just got back from HK, and while I was there I saw a bunch of advertisements warning that many stores will start charging HK$0.50 for plastic bags if you don't bring your own bag. Seems like a good move.
Yeah, that brings up another of those peculiar things about math, and especially, dealing with math culture. It's hard to talk about a main idea without getting mired in weird exceptions.

There are indeed precise conditions that guarantee that a function can (a) be integrated and (b) the integral can be differentiated, and there are subtly different definitions of "integral" that lead to different sets of extremely weird functions being integrable or not. I can't remember any of the details despite having come across them many times.

In software culture, it seems much easier to talk in broad strokes when appropriate and in precise details when appropriate. You might get an argument, but it's usually about something relevant.

> ... I know that he's confusing indefinite and definite integration.

Yes he is. The real solution is to banish the term "indefinite integral" from the language, and substitute "antiderivative". We should also not use the integral sign for antiderivatives, but unfortunately there is no well known alternative. :-(

Using the same terminology and symbols for antiderivatives as for (definite) integrals is confusing, as here. It also makes the Fundamental Theorem of Calculus -- a very profound fact if there ever was one -- appear to be something trivial about getting rid of limits on an integral sign. But consider: one can compute a definite integral using an antiderivative ... whodathunkit?
I'm a developer at a small tech startup in Portland. The quality of life here is great and there's definitely a fantastic amount of community support here for pretty much anything you would want to do. It's a very open community which is really appreciated. I would say that there might be a bit too much focus on side project and not enough on startup.

I think that everybody thrives in their own way in different places - I love promoting Portland because it'll work very well for some people. For others, not so much, but that's how it goes with almost everything.
I think their other point makes a lot of sense - It's in the security industry's interest, to keep things insecure.

Just as it's in the anti-virus companies interest to keep the threat of people getting a virus high. If no one ever got a virus, no one would buy anti-virus software.
I agree that you can't live on that, but his tax situation would likely be better than what you're presenting if he owns his own home and makes so little income, especially if he has other dependents. If others in the house work as well, then it's potentially doable. Millions of people manage to scrape by at those levels. Somehow.

From afar it may seem like central planning is the name of the game in China. On the ground, its highly regional; whith districts inside regions doing their own thing. There are high level "mandates" of sorts and a few central programs that reach deep but its hard for any program to keep control for any length of time. Mostly China is regionally run and managed.

Deferred costs is a fair deal. Of course, the bill will be large once you have to pay it, but at least it's deferred. Just make sure that it's truly deferred forever. If it's deferred for 6 months or funding (whichever comes first), it's a bad, bad, deal. Debt bankrupts companies.

This is an excellent point. Trademarks are very important. We had to buy "IM Safe" as a trademark from a public company which had acquired the trademark in one of their acquisitions. They didn't even know they had it.

Trademarks are a tricky beast, and one that can get you a cease and desist letter from a lawyer, and I hate getting mail from lawyers.
Sounds good, but there are a few problems for flowerpot.tn.us to consider.

For example, under the current rules flowerpot.com can be a mom and pop shop with a national reach. flowerpot.tn.us? Not so much, especially if there is a flowerpot.ny.us. As people starting up, that would kill many of our businesses.

This issue gets even worse outside of national boundaries, especially for those of us who live in small markets but sell to larger ones as a matter of purpose. Take abebooks.com for instance. Abe started as a small, local used book store in Victoria, BC Canada. It is by all accounts a major niche player, having been acquired by amazon. I highly doubt abebooks.bc.ca gets half the American traffic that made it a success.

I'm still a student but when I was much poorer and starving I raided a Dunkin Doughnuts dumpster and ended up with an industrial sized trashbag of every doughnut they made sitting in my living room for 3 days, until me and my roommates got sick of eating nothing but doughnuts and threw them out proper.
They're also starting to do this in Canada as well, at least in Ontario. They're also now charging for plastic bags even though they're just as poor quality as before.

Ask HN:  are big compnay IT restrictions really necessary?
I worked for a moderately larget software company (200m revenues) and we were doing just fine. We got bought by a big company (revs 1B) and they clamped down on us. They shut off IM, banned skype, banned chatrooms, banned software as a service usage (like BaseCamp), banned itunes, etc. This all was done for our "protection."

They claim that for legal reasons they can't allow any of the above. Legally they need to be able to monitor everything we do and have documentation of it.

I talked to a CEO of a company that has been thinking about going public and he confirmed to me that his lawyers advised him to shut down IM, ban iTunes etc.

So my question is: is this BS? My understanding is there are many publicly traded companies that allow IM, iTunes, whatever you want (Google, Microsoft?) Why is it that it's ok for some and not others? Does it depend on how paranoid their lawyers are?
So, the productivity increases of the 20's in essential areas like food production and household maintenance led to a rapid devaluation in the worth of the products of that labor. Hmm, so the globalization and commoditization of manufacturing labor and white collar labor is leading to the devaluation of the products of current 'service economy workers', 'knowledge workers', etc. So what is an unemployed 64 year old logic designer, programmer, and test engineer supposed to turn to for work in the future?

"They also cannot force corporations and consumers to spend. Since China isn't a democracy, it doesn't suffer these problems."

This article is full of stupid statements like the above. A democracy can do whatever the voters tell it to do, including telling banks to make loans or not make them, including dissolving corporate structures, including redefining corporate person-hood. There are _some_ limits imposed by the constitution, but even those can be dealt with.

China may or may not have economic failure on the scale the U.S. is dealing with. At the moment its really hard to say. This article contains little to prove the author's thesis.

Learning math on the internet is hard. Different people use different notations and assume different backgrounds.

I encourage the poster to read and learn more about exterior algebras! Once you've seen Stoke's theorem, the Hodge decomposition, Maxwell's equations, etc. written using them you'll never go back and those old school t-shirts with "and god said..."[1] will make you cringe.

I hope/expect to see them taught in basic calculus and physics, but it takes generations for things to trickle down.

I fully agree with the first point, that the new top-level domains are generally useless and should go away.

But country domains aren't enough. It's like the difference between the yellow pages and white pages; it helps to organize businesses and groups by purpose, while having a more generic by-location classification system for everything else.

It is also useful for domains to be conspicuous so that they can be automatically recognized as domains (e.g. for linking). There is no doubt what "foobar.com" is, but "foobar" is without context (and arguably, "foobar.cc" is more likely to seem like a source file than a country domain).
> Added bonus: If you live in Vancouver, WA (north suburbs of PDX) and work from home
> (or just in WA), there's no state income tax.

Please, please, please don't suggest that more people take advantage of this loophole! The Vancouver/Portland commute has already rendered I-5 useless, and the residents on the Washington side are currently lobbying aggressively for a new 12-lane bridge (whose cost would be paid largely by Oregon) across the Columbia to ease the congestion without taking any steps (light rail, tolls, etc.) to reduce the amount of traffic.

Portland is what it is in part because residents of the city and Multnomah county are willing to pay relatively higher taxes than those in neighboring areas for a higher level of service from the city. Our transit + public services are pretty good, but the folks who drive down from Vancouver and ride the MAX through Fareless Square to shop without paying sales tax or income tax are just freeloading.
Portland gets the same amount of rain as New York, but it hardly ever rains hard, and many people manage without even owning an umbrella. It doesn't get very cold in the winter, and there's typically only a week or two of 90+ weather (with low humidity) in the summer. Personally, I enjoy the seasonality far more than the uniform sunnyness of (parts of) California.
Isn't it weird how awful math terminology is? Even the word "derivative" is an awful choice. The special and wonderful thing about a derivative is that it's the rate at which another function changes, not that it's derived somehow.
Going solo: PC repair. Have you done it?
Hi guys, I'm a 21 year old Uni student who, like most of you, is pretty mint around computers.

I study full-time, and work one day a week at a 8-6 job. However, I find myself in need of more cash. I have neighbours up and down my road who are aware of my abilities, and often call me to fix their computers. I decided to post a rate of 50 bucks an hour, and they were often happy to pay this with a tip.

I've thought of many ways I can make money, generally looking into starting some kind of online business, however whenever I start a new venture I become too busy and simply don't have the time to give it the kind of attention it needs.

So I was thinking I'd take PC repair/advice on more seriously. Put up a simple website, print some business cards with my name and number, contact my neighbours and inform them, and if they'd suggest me to their friends. Maybe even do a door-drop one afternoon in the streets around where I live, post it on facebook. It seems like a great idea because it's largely flexible, I'm my own boss, and if demand exceeds my fairly limited time I can always increase the rates - though I'm not sure how realistic, or harmful this would be.

Have any of you guys been here? Done this? Thought about it, but something turned you off? I'm just after some general advice.
When you start talking about yourself, you are bragging and a bit of an arrogant looser. Let others praise your youtube monetization google!
I generally agree with your sentiment, but you should realize that people who live in WA and work in OR still pay OR income tax.
Silver Bullet -- Time Travelling Debugger [Google Tech Talk]

Try putting it on Full Screen and hit Pause as necessary. I was able to read most of the text, though it wasn't always easy.
Large firms have done a lot of business with a lot of companies. When we needed some urgent advice, our big firm couldn't give advice specific to the situation before a conflict waiver, which delayed things significantly.

We don't use them anymore, and I don't think there is much value added to justify the added cost of a large firm.

Do go with vanilla docs though.

In large companies they are necessary to maintain some form of control, just so you don't have your IT department running around fixing computers all day, but not to this extent. What you're dealing with are technically-challenged control freaks.
I use (setf mac-option-modifier 'meta) and then swap Option and Command keys in keyboard preferences, and that makes meta work correctly with windowed Carbon Emacs and terminal mode emacs (both Carbon and the default OSX emacs).

I also use DoubleKey to map the Enter key (right next to Command key on the right) to Ctrl. It bugs me to have to do all this, but it makes meta work just like it does on Linux, so it's worth it.
or a deluded hippy
This is a world where you can E-mail sensitive documents anywhere, log in over SSH without a trace, visit cached web sites instead of using "blacklisted" domains, use virtual host names, and set up VPNs. An I.T. person is delusional if he or she honestly believes that it is possible to fully "control" computer use.

The solution for securing sensitive material is not to do stupid things like posting it on any web site ("protected" or not), and to absolutely trust under penalty those who receive (paper) copies of it. And so forth.
This is not a governmental restriction, but rather a commercial one.

Nothing prevents a shipping company from saying "In order to take a job on my private ship, you are barred from bringing weapons on-board."

Nothing prevents a country from saying "If your merchant vessel desires access to our ports, it shall not be armed."

The combination of those two (effects, not necessarily codified policies or laws) means that merchant vessels aren't armed.
I'm republican and libertarian as the day is long, and I hate to see the expansion of government.

That said, domains need to be regulated by SOMEONE, and ICANN isn't doing a very good job (not that some government bureau would do any better).

What I got from the poster (and what would be cool) is if ICANN or some similar body were bound by some of the principles we've developed over the years from trademark law (required to be using a name to own it, can't just squat, etc.)

The other thing I don't like about ICANN is the appeals process. Can a (US state/federal) judge order a domain transfer, like in a trademark dispute case? At what level? What about international trademark disputes? Perhaps unfairly, I've always been skeptical of "arbitration" or things that look like a legal proceeding but really aren't. And the legal waters of domain disputes have always seemed rather murky to me (ianal).
Windows Mobile Race to Market Challenge
Is it BS? Yes. Is it necessary? Yes - but not to you.

Big companies are run with other people's money. These people don't trust you and/or your boss(es) any further than they can throw you. I don't blame them frankly. There have been far too many examples of why they are correct not to.

So these other people figure that the best way to safeguard their money is to make sure that you and your co-workers are legit. The only way they can do that though is by hiring yet more people to ensure that you actually tell them the truth about what is happening to their money. It's these third parties, the "auditors", that run most large companies.

Auditors have found that there is a certain set way of running companies that tends to result in the least amount of risk to the money that funds the operation. The money that belongs to someone else. Auditors ensure that the company is run according to these principles.

Ergo: the fact that some rimjob 3 states over once used iTunes to and IM to run a kiddie porn distribution ring or whatever and caused heartache for the money suppliers of that company means that the Auditors concluded that IM and itunes pose a risk to the other people that supply the money for your company: hence, you aren't allowed to use itunes as a matter of policy.

It gets even better when the government gets their hands sticky as well. Because then you get crap like Sarbanes/Oxley that basically makes being a criminal more difficult by making everything more difficult.

Public companies are not about the product/customer relationship. They are about the investment/investor relationship. You are the investment. Your job is to provide a moderate to excellent growth rate for as little risk as possible.

This is why public/large companies have little incentive to innovate in the same way start ups can, as an aside.
You're double-counting. Those overall rates include white men over 55.

Riemann for Anti-dummies: Introduction and Critique
I think a vast majority of the current problems would be fixed by auto-releasing squatted domains. There are no good domains left because they've all been squatted. They're hardly all taken up by actual sites.

How do you enforce that? (serious question)
Is there some automated polling method to see if a site has any activity? Are there "squatting police" that somebody pays to investigate these things? Are the people who want to use the domain required to bring some sort of action (lawsuit or arbitration proceeding)?

Sussman's critique of mathematical notation is hollow. The point of good notation is to hide the details while conveying the high level compactly and succinctly.

Lagrange's equations written the way he derides are a perfect example. His need to think about what spaces the symbols live in based on their context in the expression is typical when translating math to code. He should be talking about about what kind of type inference engine one needs to allow the original notation and end up with his positional notation internally.

There is a big difference between books and music/video. With books, it is not only the content but the medium that is part of the experience.

A paperback is lightweight, cheap, durable and independent of other resources. Most importantly, a book as an experience is a long, drawn out affair. Books take hours to enjoy, so it's of little importance how many I can carry at a time.

Music/movies have the opposite effect ~ they are shorter durations of entertainment, so the more I can carry, the more I can enjoy the experience. The major advantage of digital music is that I can carry my whole library with me in my pocket. Even if I could do this with my bookcase, there is little reason for me to do so. This defeats one of the major advantages of kindle.

I don't disagree with anything you say, but I don't think the death of the book will happen any time in our lifetime, or our children's lifetime to be honest.
0 is a number all right, and division by 0 isn't proving anything. My point is that maybe subtracting ∞ doesn't prove anything either.
