I work at NASA (though not on rockets), and that's a fair assessment; I think you correctly articulated what the SpaceX employee was telling you.

Aerobraking and parachutes alone aren't enough on Mars, even for small payloads (less than people-sized). Just look at the MER and MSL entry, descent, & landing systems. The reason being that mass scales with the volume while aerobraking and parachutes obviously rely on cross-sectional area. Even MSL, which is an order of magnitude lighter than a Dragon capsule, requires a sophisticated hybrid EDL system.

Also, although it may be Musk's goal to go to Mars, there is good profit to be made in Near Earth Objects and the Moon, none of which have much of an atmosphere to speak of.

Software really is sort of a special case though. Most of the problems you mentioned are at least partially caused by the constraints and resources of our physical environment. However, the complexity of software is almost entirely generated by human ineptitude. The one exception might be complexity caused by necessary optimization for hardware limitations, which would in fact explain some of problems cited in the blog post.
Perhaps you could elaborate, rather than posting vague innuendo about "how browser security works"?

I really like your idea of "pricing that scales." However, I feel the need to point out that no one can get a 1% rate on eCommerce transactions from their bank or anyone else. Interchange rates (cost) from Visa and MasterCard range from 1.71% + $.15 all the way up to 3.06% + $.10. Having said that, you're right about larger businesses finding Stripe's rates unpalatable. Maybe they're just trying to become the Square of eCommerce - which might not be a bad idea.
I'm sure I read a variation of this article every month or so. I'm sure Ive even read it on ZD before as well.

But these analysts are too short sighted to remember than when Apple rolled out the iPhone it was web apps only. That was there initial business model for the device.

They adjusted and dominated the market because of public pressure to do so. I think Apple probably have business models up there sleeve from years ago they never implemented.
Its anyway the banks fug the customer. Either directly or indirectly using merchants.
Good Lord!! What are you saying?? That because there aren't "qualified" people that we should leave the current criminals there, even though they jeopardized our entire financial system!??!?

There are plenty of people that could have run the banks. Sheila Blair perhaps? I'd be okay with Elizabeth Warren. Hell I'd even take Jim Cramer at this point.

The marginal cost on a Space Shuttle launch is actually rather low--a few tens of millions if we kept up with the original launch rates (less than the cost of a Falcon 9h!).

Also, no work was ever done to bring down operational costs. In fact, such costs ballooned as the program dragged on, despite numerous design studies showing ways to reduce them.

What does "Sign in with Twitter to contribute" mean? Does that mean I get to contribute to the discussion by posting a reply if I sign in with Twitter? That's what "contribute" means to me, but it seems unlikely, especially given the relative paucity of posts in this discussion.

I wouldn't bother making a comment here to ask; normally I would just sign in and see for myself. But this app wants permission to make posts to my Twitter account, and I never, ever do that. (I hate it when I sign up for something and I later find a post in my timeline that says "A-hyuk hyuk, I just joined SomeSkeezyWebsite and I'm having a blast, LOL!")

Removing the home mortgage tax deduction will cause the price of houses to drop, because no one would be able to afford the more expensive houses anymore, and they would have to drop the price to make them affordable.

The only thing that the tax deduction did was to raise the price of houses.

Hey memset,

I bought the fully assembled product because I felt the kit version was significantly overpriced compared to the bare PCB and the $5 savings was not worth having to assemble it myself. I hope you're making a good margin on it! :) Regarding comments from others about the possibility of poorly regulated PSUs: you are absolutely correct! I verify the performance of the (higher quality) PSUs that I use before I hook them up to my projects. I've already created an integrated version of this that has worked wonderfully and I am excited for this more versatile solution.

All HN threads attract posts with excess ratios of certainty to knowledge.

On the technical stuff, the excesses are met with really knowledgeable rebuttal, driving up the denominator. People are afraid of embarrassment, so they write more carefully, driving down the numerator. The dynamic drives the overall ratio to something like one.

On economics, everyone is really sure the other guy is crazy. They make posts that drive up the numerator, as that's the only way to get heard, and drive down the denominator, as they must address the other guy, whether they know anything about the matter or not. The average blows out hyperbolically -- if there's a limit, the signal / noise drops too low for even the craziest people before that limit is approached.

It's kind of remarkable to see how quickly those ratios go to their logical endpoints.
If you're interested, there are two things I've been meaning to update about this script (I promise I will merge your pull request!)

1. The measurements do not take the laser's kerf into account. That is to say, it does not account for the thickness of material burned away by the laser, so the resulting faces are a bit loose.

2. If you look at the design, the tabs (where the faces fit into each other) go straight across. It would be better if the tabs were smaller, and then have several of them fit together across the length of the box, rather than one long tab.

On one hand, I really hate the Economist. It's a magazine that thinks an ideology, a smart tone, and providing the only decent coverage of world events widely available makes for a compelling magazine. Even if that coverage is ridiculously biased and not really knowledgeable about facts on the ground.

On the other, it's perhaps the pre-eminent mouthpiece for the ruling Anglo-American elite, and it's comforting that they're sounding the alarms to what's happening. I think it's too little too late, but I genuinely hope that people and policymakers hear them.

Because this is really bad, folks. Really, really bad. It's pretty clear the dominoes that will fall: Greece fails, setting off markets and destroying banks across the continent, causing Spain to fail, doing the same, causing Italy, Belgium, maybe even France to fail. Who knows what after that. The EU's demise will signal the financial collapse of an economy larger than the United States; it's already either at the brink or already in a new recession, and this will be the deathblow. The quick succession of collapses, happening all within the span of a month or two, reverberate throughout the entire world, throwing the USA back into a second, possibly harsher recession than the first we have yet to recover from.

The only other solution is converting the European Union into a fiscal union. On the face of it this is implausible: you'd be asking Germans, who in their self imagination see themselves as pure as snow, to pony up hundreds of billions of dollars to subsidize what they see as the lavish lifestyles of lazy unproductive Mediterranean types. Even if you could form some political consensus to do this, though, it's not even clear that politicians could coordinate the solution in time to cut off the collapse. Effectively consolidating dozens of countries into the same fiscal union isn't a change you can implement by sheer willpower; it'd be a herculean task even with years of preparation.

And, stateside, any attempt to counteract or prepare for this tidal wave is simply doomed because of our ridiculously broken institutions. One side has the ability to co-operate and try to fix the situation, but because of how our government is set up all the incentives on their side are to actively sabotage the economy--regardless of causes, if it does badly, the party of the current President will be blamed.

Because people (Americans, Germans, Greeks, Chinese) are all idiots, from the man on the street to the upper echelons of power.
Can't recommend Schwab enough. The no international ATM fees is amazing when traveling (especially if you are going between countries since you tend to get killed on those secondary conversions if you take out large sums). The only disappointment I've had with them is that my Invest First credit card (2% cash back on everything) is going away at the end of October, because surprise, surprise it's being taken over by BoA. They (Schwab) recently rolled out check deposits from their app so BoA taking away my most used card and implementing this fee structure I'm going to get rid of my account secondary account with them and use just Schwab.
Until your revenues are huge I think your idea is fine. Keep as simple as possible. Leave a bit of profit in the Delaware company. Keep your paperwork straight.

This is pragmatism, pure and simple:

- you are making sales (yay)

- if you get audited the challenge will be on the basis of the price that your European company gets from the Delaware company. The worst case outcome probably isn't too bad.

- Unless you are making tens of millions, your Delaware corporation will be a tiny taxpayer among all of the corporations in the USA. Low profile. Clean paperwork. Don't attract attention etc. :-)

- one last thing. Look at the treaty between your country and the USA. Sometimes there are odd little things you can use to pull business profits out of the USA easily and without tax. Or less tax anyway.

If you don't make a sale you don't have a tax problem. So first make a sale.
Making things simple takes a lots of work. Things are complex because the problems are complicated. That's why you got paid the big bucks.
You can deposit your checks at UPS stores. If you only rarely use checks this works well as a solution.

noob mistake

There is very little value in trying to draw generalisations from past experiences when it comes to deciding whether to use a framework, and if so, which framework to use.

Unless you're reinventing the wheel, each project will front you with a unique set of challenges. More often than not, with a framework, these problems are awkwardly solved with code written by other people to solve other people's problems.

In my opinion all of this has less to do with what's trying to be achieved than it does with what you personally want to take away from the experience. If your motivation is to make money quickly to feed your family then you would be silly not to jump on something like Rails and ride on the shoulders of giants. On the other hand, if you want to become the most proficient programmer you can become then this path will probably lead you astray.

A quick look around the internet reveals both tiny projects that fail, as well as enormous projects that succeed, on full-stack frameworks such as Rails.

Needless to say if you're hacking on node you are of the latter category; The developer striving to broaden her horizons by exposing herself to the news and unknowns. This won't help you learn to work in a team on a large project. It wil not teach you to control complexity. In fact, it will probably lead you to believe you're learning all these things when you're in fact becoming comfortable with the complete opposite (working alone, hacking in anything, anywhere you feel like).

Generalisations really piss me off.

I whole-heartily encourage anyone who is open-sourcing node.js code to continue doing so. Even if it is Yet-Another MVC framework. Just take note of what ry is getting at here by keeping it mean and lean.

Amazing product, just curious about which font was used in the stripe logo?
I just received your order. Thank you!

The margins on this are not bad, but I wouldn't say they are stellar either (for some definition of "stellar") You can look at all of the components/PCB/acrylic and back-of-the-napkin estimate its unit cost, not to mention shipping+assembly (hand crafted!)

You raise a good point in terms of the non-assembled version only being $5 cheaper, which is further confused by not wanting to undercut distributors' (okay, one distributor thus far) prices.

It's interesting, because I've never really had to worry about these kinds of issues (pricing, distributors, expensive unit costs) in the past; it is kinda fun to look at a project from these other angles, orthogonal to the pure engineering component!
The Economist would be a lot more credible if it admitted that yes, they want the Germans to subsidize the Greeks and no, there is no plausible scenario under which those subsidies end.

Absent that, they look as rhetorical as anyone, if somewhat better written.
I think their vision used to be "Be good at email and good for businesspeople"

At some point, they said "Hey, these touchscreen things are doing pretty well, let's get into the consumer market." But they had no idea how, and they've been releasing weak phones on a weak software ecosystem ever since.

On the other hand, if they'd stayed in their original market, I don't think it would work out much better. Doing enterprise features nicely is great, and could sell a lot of devices. But Apple's "touchscreen on a little computer" model is flexible, and all it would take is an enterprise focused software update from Apple or a few well written apps from a third party.

Competing against Apple's vision and manufacturing skill is going to be difficult to do, and in the long run I don't see RIM being one of the companies that manages to do it.

"Bold" action by the politicians and the central banks created much of the current mess.

No, bold actions by financial instrument designers, sellers and buyers created much of the current mess. Agreed on the crony capitalism and ad hoc intervention, and the real shame is that the cowboys who got us here did great out of the deal, but let's lay the blame appropriately.
This is hopelessly naive. The reason that the whole stack of a solution isn't in proportion to the problem it solves is that we have more than one problem, and the only way to scale our manpower to all these problems is share some of the common bits in the solutions.

This sharing creates new abstraction boundaries, increases the number of concepts and moving parts, and there are lots of compromises involved in reusing a common part compared with crafting something small and simple specific to the task at hand. But if you didn't do this, you'd have lots of duplication of similar, but not quite identical work, like a pre-industrial society; a massively inefficient use of human labour.

The documentation took a long time. I went from no documentation, to a 30 megabyte PDF I created with OpenOffice (not recommended), to borrowing a friend's light box and buying InDesign to create a pretty neat assembly guide.

Coldfusion is the best development platform
Kind of depends if this is simply an integration (e.g. a feed to/from Hadoop), another key-value store (OMG, not another), something like composite column types (ala PostgreSQL), a re-birth of Object DB Extensions (please not) or smarts structured data (e.g. better XML search). All of those feel like a band aid. Would love to see something truly innovative here.
I thought remote deposit was available to folks with an insurance product or a line of credit (a simple credit card, for instance) with USAA? Or maybe it was an AND and not an OR?

Edit: I'm wrong. It does indeed require that you're eligible for property and casualty insurance, that you have a checking or savings account, and that you have or qualify for a credit card or loan through USAA.
Good thing we bailed these guys out...
It is, in fact, a heck of a lot more complicated than that. Mostly the U.S. went to the moon to provide civilian cover for R&D investments in I.C.B.M. and satellite surveillance technology.

People work on what they want to work on. Product development is driven by whoever wants to drive product.

That is the surest way to reduce your startup's odds of survival. In this case, it would become a prototypical case study in survivor bias.

GitHub is lucky that they are building a product that is tailored for developers. It makes their survival rate doing this slightly higher because the developers are (only vaguely) similar to their customers. The further these two points are from each other, the worse this advice becomes.

A startup needs somebody who understands how to drive products into markets. Whether this is the CEO or a product manager hired off the street doesn't matter, but they need somebody doing it who has the real authority to turn those learnings into a product fit for a market.

FWIW, I've lived the flip side of this coin: building a tool for developers driven by what we thought would be cool to build instead of having a product guy hitting the street to understand the real customer. After burning through more than $20M, the lights got turned off.

There is still something HTML5 can't beat: games and heavily graphics apps in general. That and C will always be faster than JS+html on heavy graphic. Unless HTML5 finds a way to bridge that gap (maybe with dart?) but even then it's not highly probable and not in the near future anyway. And if it happens, Apple could still offer those HTML5 apps as stand alone apps in their app market. Sure, people would be able to get them from the web, but the the market exposure will still be a big boost for developers and so the wall garden will still be there.

Look at the apps Google removed from the Android market, they got significant less downloads as people had to visit the app site to get them.
