Regarding credit card security (or lack thereof)--protection lies mainly in the massive fraud prevention efforts of the credit card companies (hence the large fees). It gives more protection to consumers than merchants (it's easy to request chargebacks). Bitcoin offers an alternative security model, known as caveat emptor. There's no way to reverse a transaction. All consumer protection devices, such as escrow, are outside the scope of the protocol. So bitcoin by itself may or not be an acceptable means of payment, depending on the use case.

I understand the risk of a single party attacker who controls more than half the network. But at this point, what kind of attacker can muster up that much computing power? Only a nation-state, billionaire, or large corporation could conceivably do so. And it's daily growing beyond their reach. Not only that, but their motive must be not just to make gains. They would have to want to destroy the bitcoin economy. Interestingly, the bitcoin economy has already survived a 24-block split without major calamity[1].

I had a look at the papers you linked to. The Canetti paper certainly seems more rigorous and formal. But the Danish Beet Auction paper actually doesn't seem too far from the Bitcoin whitepaper. The bitcoin paper is certainly the most concise.

Amateur or not, bitcoin may be the "worse is better"[2] solution to low transaction fee, decentralized, online payments. If a better solution comes out, I'd love to hear about it.

Wow, I was curious as to how bad it could be ...

It's bad. The first video that came up on YouTube is an episode on the official Disney channel[1]. The plot involves exactly what you said: consistently snarky comments, combative conversations, extreme sibling rivalry, ditzy parents, a kid stealing food (and then not being remorseful or understanding why he shouldn't break into a neighbours house), and generally poor role models all around...

It's essentially That 70's Show without the direct drug and sex references.

A caveat: 60/20/20 might work for reasonably sedentary people.... Most people doing exercises, especially resistance exercise, will want much more protein.

40/20/40 or relatively close to that is a common split. Many will up the fat too (at the expense of carbs). At 60/20/20, there's absolutely no way I'd manage keeping up my lifting program.

Vim is more or less a superset of vi. Even still, there are some subtle behaviors in real vi that do not work the same in Vim, even in Vim's "compatible" mode.

Of all the vi-like editors, Nvi is much closer to real vi than Vim is.
I gave up looking for the perfect set of bindings and just switched to using evil-mode. While not perfect, definitely good enough and widely used.

Emacs' default bindings are also widely used but the chords are indeed horrendous.

I find it interesting how much TextMate has declined. A few years ago, I believe it would have been the #1 response on this list. TextMate 2 these days, in the hands of the community, is truly excellent. The UI and UX has improved tremendously, and it is now free and open source. I imagine it is just too late. Everybody has moved on.

That said, I'm a switcher, too. I got fed up with the vaporware situation and moved to vim full-time a few years ago. I couldn't move back now.
I've made this move recently myself, but I'm a little surprised how completely Sublime Text has hoovered up the TextMate constituency.
At least with username level redirects this decreases the number of available usernames, unless this is somehow taken into account.
Nah, I have remapped those keys and the problem for me is the chords which sometimes require three or more actions for commonly used commands.

I don't think the food industry would be too worried about lost revenue. They will be more worried about the cost of having to create and replace whole new ranges of products to fit into these guidelines, but in the end they will deliver the same wide spectrum of foods as they do today and fit into the guidelines. Perhaps it will raise the prices of the products generally, which will help with overeating but will also make products falling outside of the guidelines more attractive. The irony is that in 10 years time our 'understanding' of what is healthy and what is not will probably have changed radically.

The problem with nuts is that a reasonable serving is very, very small. If you get people to actually buy and take a decent (calorie wise) serving and eat it slowly, it works great. But it's all too easy to eat a 800kcal-1000kcal bag of nuts without thinking about it.

I think a huge part of the problem in general is large packs of food. Ready-made sandwiches in packs with 800-900kcal, for example, or nuts or high-calorie drinks sold in quantities that ought to be anywhere from 2-3 to 10+ servings. Ready-meals that comes only in massive portions that might work ok if you're buying it to split 2 or 3 way, but that are often horribly oversized if you eat alone.

It's all great and economical when you're buying stuff to put in the cupboard and have the willpower to resist eating larger quantities, but clearly we can see that people don't. And unfortunately there's little reason for most manufacturers or supermarkets to offer smaller alternatives, as we're too easily seduced into buying the larger packs.

Personally I found my soda intake dropped substantially after I started buying my weekend soda "allowance" in 250ml bottles instead of 0.5l or 1.5l bottles, for example. And a lot of my other diet maintenance boils down to picking smaller containers, smaller plates, smaller glasses for everything except water.
Everyone is entitled to this data. The fact buses are late where I live are a given, if I asked traveline to give me the data so that I could measure how late my buses are, they would decline. Opening data can only help to increased accountability which can only lead to better services for customers. If your data brings your company in to disrepute and your way of fixing that is to hide the data, you're doing it wrong.
Yes, there would have to be some negotiation/matching on price. I'd see it as an iterative process, whereby a set of backers post a problem, with or without a cost estimate. The solver puts forward a proposal with estimated costs and each backer chooses whether they want to accept that proposal. The process then iterates until a tipping point is reached in the funding.

Good idea to see it as an addendum to an existing service rather than a service in its own right. Or an amalgam might work, whereby the "kickstarter for problems" is a separate service, but on reaching the tipping point the project morphs into a regular kickstarter project, that has already reach its tipping point. This would require each backer to also have a kickstarter account (if not the kickstarter project would come up below its tipping point), but it would save a minimum viable product from the complexities of having to handle money.
Most of the "velocity change" in your math is done by the Sun as heliocentric potential energy converts to kinetic energy or vice versa. The minimum energy trajectory from Earth to Mercury is about the same delta V as Earth to Mars.

The problem with Mercury is you can't aerobrake, so add either a Venus slingshot or significantly increased delta V requirements to decelerate and land.
What I'm comparing is the satisfaction hit you get from having a greasy pepperoni pizza delivered and devoured in 20 minutes and eating something completely different depends totally on lifestyle and mood.

What the OP was implying is that fast/junk food is inherently irresistible and that's why more people are obese. What I'm saying in turn is that it's today's lifestyle which makes people find it irresistible and that nothing else satisfies.
I completely agree with your second point. The emphasis should be on problems rather than the "ideas". That's how real innovation works. Ideas are cheap, abundant and mostly unimportant. Problems and challenges are the real thing.

For me the main reason is consistency. I can write apps in Python, Ruby, node, etc. and configure them all the same way.

The envdir program (from daemontools) is useful for setting environment variables in a shell-agnostic way, e.g., run your app with:

envdir ./env python app.py

> "correctly handling unicode" can be subjective and case-dependent...

So is correctly handling integers.

> I think making only minimal guarantees and punting to the application is often the only sane course.

That is completely and utterly crazy, the average developer has neither the knowledge nor the resources to make anything but a mess out of it without proper tools and APIs. Even with these (including a complete implementation of the unicode standard and its technical reports) unicode is already complex enough to deal with.
You're saying the food industry optimizes for irresistible (crunchy, fiberless, fat and sugar rich) food and there's no way around this formula. I'm saying they are only selling what hungry, depressed and stressed people are craving to eat.

Well yes, but solving problems like depression, stress, and overly-long working hours is much tougher than just blaming food executives.

How could you have forgotten the standard text editor, http://www.gnu.org/fun/jokes/ed-msg.html
The whole point with many meals a day is not waiting to have a giant munchie to eat, because when you do so you'll look for high-fat, high-sugar food and devour an insane ammount of calories in minutes before your body triggers a sensation of satiety. Then depending on your genetics and level of activity, you will get malnourished, obese or both.

You stopping having hunger pangs in the mornings after some days is your body adapting to your schedule. As long as you don't go lunch with a blackhole in the stomach and are mindful about what you're eating, it's fine. Still, eating something in between is important to avoid wild sugar peaks and helps improving cognition performance if your job is intellectual.
> I generally agree with you, but I don't think this:

>> the population is acting entirely naturally and appropriately given their adaptation to specific evolutionary conditions

>> there is nothing wrong

I think by "nothing wrong" GP meant "people are behaving exactly to specification", not "people are behaving in a way that benefits them". Lots of adaptations are quite wrong for life in XXI century, but humans executing them are acting correctly, with respect to the way their hardware is wired.
Ugh, that's awful. I have on occasion been made aware how atypical my educational experiences have been. My secondary education was filled with teachers who made it very clear that if I wanted to know something, it was always safe to ask, and that I would be rewarded for my intellectual curiosity.

I've only had one memorable explicitly negative experience where I was openly mocked for asking about something outside of my experience, but my indignation far exceeded my embarrassment in that incident.

I keep a text file on my laptop named "youcantalktoanyone.txt" with the contact info for a few people who's work in interested in. One by one, as I have something to contribute, or need clarification on their work, I get in touch. I forget sometimes how lucky I've been.
I'm sorry, but can we stop calling these startups?

Companies like Twitter, eBay, GitHub, Mozilla, Netflix and Atlassian are past the startup stage by now. Many of them have been market leaders for years.

Calling Intuit a startup isn't even stretching it anymore. They're 30 years old and have a revenue of over $4B.

I realize HN thinks startups are sexy, but these have no business being labeled startups. If Intuit is a startup, what does it take to be a called a mature company?
I'm not sure you understand what's going on, which is probably why you've been downvoted. The secret token ensures that the server does not need to trust the client--that's what signing or encrypting session cookies does.

Authentication on every request requires you to store the user's authentication details on the client, which is considerably worse for security purposes than a signed or encrypted session cookie.
> For information which functions as advertising to also be a candidate for fraud it must first assert something as fact.

That's sort-of fine, again, when dealing with competent adults. Though plenty of research demonstrates that even competent adults are incapable of avoiding being influenced by good advertising in ways that may very well be against their own interests.

But when targeting children, it takes very little before your slight manipulation gets treated as if it was fact by young children. That it isn't "asserting something as fact" by adult standards is meaningless when discussing advertising that is targeting children.

And as a parent: Short of locking my child in the house with no access to any media, there is no way I can prevent my son from being exposed to advertising that he (at 4 years old) is in no way prepared to objectively assess the fact content of.
Well, because it's prison. By historical standards, this is pretty mild.

I'd like to know why we have so many awful laws on the books. Seems like we have so many, that most of us could be locked up, if they happen to irk the wrong people.

I have an irrational hatred towards SEO. People should stop investing money and time in trying to influence an algorithm that constantly changes and actually invest that time and money in creating better content or a better service that people actually want.

It will also make for happier web developers because we won't get stupid clients come in and ask for us to do some crazy stuff they read in a pdf somewhere online on a guru's website ... btw.. stay away from whoever calls himself a guru (SEO guru, code guru .. what-not-guru)
I agree. Calling Intuit a startup is like calling USPS an up and coming disrupting force in the mailing business.
So is it that we have to eat unhealthy at the gun point? No! We are free to eat whatever we want. And if most people want to eat poison then that's what the free market economy will provide them with.

It reminds me a little bit the situation with the banks. Somehow when times were good and everybody and their uncle could get a loan everybody loved Goldman Sachs CEO. But now, when it is pay off time people just hate the banks. Just shows a hell lot about people's attitudes (me! me! me!)

The same with the food industry. It's not my fault I eat like pig day and night, it's because the commercial on TV told me to do it. Sure, and if they told you to eat shit, you would eat shit, right?

Socialism is the love of blaming somone for your own failures. Free people not only make decisions, but also take responsibility for them. People who don't, should live for some time in a country where 'Dear Leader' will decide for them how they should live their lives because there is no difference to them anyway.

I'm tired of this BS. Used to have a coworker who was eating all the time. She had a small refrigerator in her cubicle. And of course, yeah, she wants universal healthcare. So I and others will pay for her bad choices. This is just immoral.
One thing about this whole discussion really bugs me:

Everyone is just talking about how to keep the children occupied with technology. I really think this is the wrong approach, there is so much more to learn and explore than stupid pixels on a screen.

When we were young my parents had the attitude that it's very important to get a "feel for the earth", in a very literal way. That's why we spend as much time outside as possible. One of the few things I remember about primary school: I was the only one who knew potatoes grow below ground. Where has this world come, that our children know so little about even the most basic stuff??
This is one of those things that varies across the UK thanks to devolution: Scotland bans raw milk products, but England and Wales don't IIRC. Even in England, you can only buy raw milk / cream directly from the producer. Raw milk cheese is available in ordinary shops though.

I can go into my local small supermarket and buy pasteurised, unhomogenised milk from Jersey cattle which is very, very rich. Fantastic for making custard!

The definition of what you're allowed to sell as 'milk' is probably set by the EU somewhere, but I've never seen milk have added ingredients listed, unless it's something like chocolate milk.
also UK sometimes is a test market, why? (nearly) the same language as in the US, but not as a dominant market as the US. (the same reason why we german natives test new websites with switzerland)
It is not a text editor.
Interesting yes. Useful.....not so much.

The ability to view a company's stack changes over time might prove more useful. For example, what stack did Company X use to get to 10k users, 100k users etc.

Given enough accurate data then it may be possible for a visitor to predict any performance bottlenecks that a technology may enforce over time and what technologies to use to mitigate said problems.
Due to a combination of long processing times for green cards, and the legal notion of "immigrant intent", H1-B is commonly used as a bridge to a green card.

Any US visa which isn't a green card (e.g. tourist visas, student visas) is considered a non-immigrant visa. You can only apply for, and enter on a non-immigrant visa if you don't have immigrant intent. If an international student, for example, applies for a green card, this shows immigrant intent and they could find it difficult to renew their student visa or even to re-enter the US after traveling.

Obviously this wouldn't be a problem if the green card itself were quickly approved, but the process is bureaucratic and can take years even for people with advanced degrees.

H1-B visas, on the other hand are one of the few visa classes that allow "dual intent", meaning that while they're non-immigrant visas, H1-B holders are also allowed immigrant intent. Which makes it a good visa to have before starting the green card process, if you want to be able to travel (e.g. to visit family) while your application is pending.
A lot of the time, the measures the state needs to take to protect children includes protecting them from actions of parents that might very well be well-meaning, but just as clueless and easily manipulated by advertising as their children, but all to often even don't care.

While I'm for reducing the power of the state, protection of children is not something society can abdicate from without severe negative effects.
What kind of things are you running there? I have some small not so important sites on NearlyFreeSpeech and have been happy -- would be nice to hear about their limits.
jEdit. I'm surprised nobody seems to be using it considering how powerful it is. I have tried many editors over the years and SublimeText is the first one that comes close to it; but jEdit still has much better search functionality, especially in 'hypersearch' mode.
Interesting. I like HTML, but can't imagine that it is the pinnacle of development. Surely we won't be writing it in 20 years time, right?

One thing I would love to hear more is how do you deal with CSS? If everything is generated on client, do I need to "reverse engineer" using inspector?
He said many. I agree with him: Intuit, Twitter, eBay, GitHub, Mozilla, Netflix and Atlassian are hardly startups. And this list is by no means exhaustive.

Sure, many others may be startups, perhaps even most. But since when do we generalize away ~30% of some population. That's not very scientific. I can't think of many scenario's where this would be acceptable.
