What do you mean by sessionless?

Do you mean storing everything in an encrypted-and-authenticated JSON Web Token? Check out Slim 3.0 when it gets released (coming soon I hear).

Do you mean no sessions and no cookies, ever? You can use any stack, really. Basic PHP does this by default if you don't invoke session_start() anywhere.
If it knows what pieces you access, how do you prevent the sever from learning ordering?
It's going to be cheaper, but still in the millions, and not just because you still need to pay for a new second stage. There's also nontrivial cost associated with range safety, payload setup, and so forth (which are operations that still involve lots of highly trained personnel, with limited opportunities for automation because, among other things, the payloads aren't all alike).

I get that the idea that we "went to the moon with a slide rule" and similar ideas are appealing, but I'm not convinced that your statements are resting on a basis of fact.

For one thing, I'm not convinced that your mental models of what a "mission computer" is and what a "mission computer" would be doing, or when, make sense from an engineering perspective. I'm also not convinced that you know what an orbital perturbation is, nor how they would be used to plan and fly a mission.

To take an example from aviation, we didn't have practical simulations of general viscous fluid flow in the 1960s, but it would be meaningless to say that we "used Bernoulli's principle" to fly across the Pacific.

The Apollo vehicles had an on-board IMU. A trajectory could thus be pre-planned and flown to using feedback control. That trajectory would certainly have been calculated ahead of time. Thus, while there would be no need to have "[done] the math involved dynamically," that by no means implies that patched conics were used while in flight, nor does it imply that they were in any meaningful way used for the final design of the missions' flight paths.

Further, on any deviation from the planned flight path, numerical integration methods would yield results that would be good enough for later correction, again, by using feedback control.

If you still need to believe that "KSP math" is how we got to the Moon, go ahead. You've certainly done nothing to convince anyone else, though.
This seems more like a cheat sheet of applied mathematics with CS flavoring than a theoretical CS cheat sheet...
okay, this old trope again. anyone who has a $100/month plan has it on their website. it's 2015, saas is a thing now.

nobody is going to make you call them for $100/month. ~$3k/month or ~$10k lump sum is roughly the threshold for enterprise sales that require you to talk to someone.

they do this because anyone who pays anything less than that for an enterprise service or product is going to be a demanding, unreasonable, cheapskate, entitled, caustic asshole because they're not used to spending large amounts and the money is probably coming out of their pocket (small business or soho customer). nobody on earth wants to deal with that kind of customer.

the phone call is designed to filter people out who get annoyed at needing to talk to someone. if you don't want to talk to anyone, you don't want to spend real money, because people who spend real money want to talk to real someones, usually multiple someones, the more someones the better. nobody wants to deal with the 'in between' customer who is too big for their consumer britches but won't step up to spend money for a real solution where real people on the other end of the line give a shit about their problems.
Yes, definitely cost prohibitive from a fuel perspective to change orbits, but the vehicle could be safed for future use. I do not have enough information as to whether though would be valuable unless Tesla as some way to produce fuel on-orbit for the waiting, safed second stages.

We considered building on Mixpanel (and still are open to it) — we were 100% certain that Keen IO had the API we needed, and we liked that their business model was in line with what we're doing.

Also, I was worried that since Mixpanel is somewhat of a competitor, it wouldn't be wise to use them as a foundation.
> My biggest two takeaways contradict themselves: I wish I had started sooner, but I’m so glad I waited. I had the idea from the beginning so it’s painful it took half a decade, however I never could have made it happen five years ago.

This is very inspirational, and very true: the ideas I had years ago I could never have brought to life, and I probably would have failed, badly, at the business side. Today, I can bring things to life, and I'm understanding more and more of how businesses run.

That's exactly the use case. The idea is that the data isn't decrypted until the client.
I'm assuming they mean clients. While the term "lead developer" isn't uncommon, leads is a marketing term for prospective clients.
I know this article is referring to a different kind of gaming, but back in the day, I used to give potential candidates a NES controller and Tetris when they were in the waiting room before the interview... You can tell a lot about how a person deals with time constraints, pressure and approaches problem solving by watching somebody play tetris for 4 minutes. Not that Tetris would be the only input into the decision, but it was a thing.
The best way to buy cars is option out exactly what you want and get the invoice price. Personally I've used carsdirect.

Now with invoice price in mind, send emails to all dealers in your area. Simply explain you want X car @ X price and that you are emailing many dealers and will move forward with the dealer that has the best deal. Its important that you compare cars across dealers by the difference from invoice price as small options will change the price of the car slightly.

As you get quotes, you can forward those to other dealers if they have the specific color you want, etc.

Once you lock in a price, take care of financing through your local credit union. Show up to dealer, decline all warranties/addons, sign the papers making sure price is the same you agree, and off you go.

Just did this about a month ago and it worked out great. Remember to calculate exactly how much DMV fees will be(usually around 2-3 hundred dollars) which will likely be on top of the price you negotiated unless you specify otherwise.

Don't tell them you have a trade in until you show up at the dealer to buy. Then you can negotiate the trade in value without them trying to move numbers around with the car price.

I like this approach because there is zero advantage to negotiating the car price in person. Via email you can take your time to research and also field many more offers and quotes than you would ever be able to if you visited each dealer physically.
Would you agree that the suck of filing would be significantly less if you could just snap a photo with your phone, push it to an application, and later just have to handle some details on the filing?
Once you already have an Arduino (one with a DIP socketed AVR chip like an Uno), a great option is to just buy ATMEga 328 or similar ICs with the Arduino bootloader burned on them and build standalone circuits around those, which requires only a 28 pin socket, a voltage regulator, a 16mhz crystal(or whatever clock rate you want to use), and a couple caps. Your Arduino board basically then serves as a programmer for the AVR.
Technology is making war increasingly unfair. If you look in the past, a decent percentage of wars were won even one one side had massively less resources. Not the majority, but still like 30% IIRC.

With mass surveillance you can detect and stomp out rebellions long before they amount to anything. With automation you barely even need the support of your own troops. With modern technology you can keep most of the population fed and happy enough they aren't willing to risk fighting.

And so we could get stable authoritarian states like 1984.

But really you don't need all that to begin with. The vast majority of societies through history were pretty unequal. Even today much of the world has pretty high levels of inequality. Technology just prevents that from ever changing.
An_message: Format Agnostic Data Transfer (AppNexus Tech Blog)
A very good point! "But the doubling time for transistor density is no guide to technical progress generally. " I would claim increased CPU power has been detrimental to technical quality for some existing products. New features could be added without detailed understanding - "it's only a few percent slower than before" - but with increased processor speeds the code gets worse and worse as performance drops are not a business problem since increasing CPU speeds will take care of them. Until, of course also other problems start to arise due to shoddy work. And then suddenly the free lunch is over, multithreading is required amd at which point the maintainers enter a mutex hell. "Abandon all hope, ye who enter here". Increased processor speeds can either be combined with better algorithms to create magic... or just hide slapdash hacktastic patchwork.
Is there a link to just the code somewhere?

It seems that he's mostly considering the value of the idea of economic rents in terms of how well they explain corporate profits as a means of testing the idea of economic rents themselves. However, the core idea of economic rents comes from analyses of land rents and monopoly rents in the 19th century: application to contemporary corporate profits is a derivative application of the idea.

Land rents, for example, were the rents generated by idle 18th and 19th century gentility simply for inheriting the land at the basis of economic production in an agricultural economy, rather than for contributing useful labor towards agricultural production. This idea has gained renewed attention with the rise of extreme inequality and inherited capital.

He also seems to be conflating these different kinds of rents together: land rents, monopoly rents, IP rents. The economic value of IP rents can be easily seen in patent trolling, defensive patents, &c. But trying to explain the corporate profits in terms of unspcified "rents" sound more like a project to discredit the idea of economic rents by conflating a lot of variables. That might be because I'm skeptical that economic rents are a predominant explanation of rising corporate profits, of course.
"The price premium of using AWS is high enough that it's trivial to afford leasing tons of excess capacity to handle failures and still save tons of money."

"AWS certainly is convenient, but it's also so expensive I'm charging my highest day rates ever for projects to help clients move off AWS these days."

This is FUD and nothing more than FUD. As bad as the article the other day that said a company saved 50% moving off AWS. Show me a company that can save 50% by moving off AWS, and I'll show you a company that isn't using AWS properly at all.

When you compare a single piece of hardware that you can buy and run yourself to an instance in EC2, you are leaving a lot off the equation.

Such as:

Deployment tools (CloudFormation, CodeDeploy, EB, OpsWorks)

Monitoring tools (CloudWatch (sure it leaves some to be desired)

Machine Image building/tracking tools

Hardware provisioning tools

Security tools ( Security Groups, NACL's in VPC, plus the stuff you don't see in the infrastructure)

More varied hardware than you'd have in house.(different amounts of ram/cpu/storage).

More hardware than you'd have in house. (no need for spare parts cabinets, waiting on vendors for replacements).

Storage (EBS, S3, local).

When you pay for EC2, you get all of this. Doing this yourself isn't free in any way shape or form, even with opensource tools. A company with a good ops team that is cloud savy is going to be several times more effective at a smaller size than a team that has to manage a datacenter, all the hardware, and all these other bits. Folks discredit all of these when they do apples to apples comparison of hardware you can buy to a service that you use.

Let alone that most people don't understand per-server network, space, and power cost over its lifecycle. (I've spent months with companies doing datacenter ROI analysis and having no idea what things cost).

And going to a managed hosting provider, you're either locking yourself into the frozen tech world they are in, small development resources, and typically constrained resources. You don't hear of managed hosting providers building any of the above themselves, so you continue to have a higher management overhead than a true cloud provider like GOOG, AWS, MSFT.

1. If you trade your old car to Tesla, you still have to negotiate it's price.

2. I am not sure how is your opinion about price is related to the experience at the dealership. Sticker prices for all cars are available online, and you can make a decision if the car worth that price well in advance. Once you make that decision nothing is stopping you from having a great car buying experience.
2 CRAZY Korean backpackers' video interview project
Hello Hacker News.

My name is Mikey Lee. My partner Hyuk and I came to San Francisco from Korea 6 days ago to for our video interview project. We aim to interview entrepreneurs, programmers, artists, and other self-motivated interesting people in this region on camera and deliver their story and insights to our subscribers.

On our second day here, we successfully interviewed Saeed Amidi, the CEO of Plug and Play (http://www.inc.com/jill-krasny/silicon-valley-matchmaker-saeed-amidi.html) and after we uploaded his interview video to our Facebook page 2 days ago, it generated 19k views so far. (https://www.facebook.com/stage5)

We are backpackers doing video interviews. Starting here in SF, we plan to travel around the world and interview people with different backgrounds. Our current focus is on startups.

We are interested in people that enjoy a sense of pride and fulfillment from the things they do. We are inspired by people who have walked through unpaved roads. We love people that are driven by purpose and craftsmanship. These are the people we want to invite to our interviews.

So if you are one of them. Leave a comment here or send us a email at mikey@stage5society.com. I'm also open to fb friend requests (facebook.com/jkl1384) but my posts are mostly written in Korean. We are here to build relationship with people, not just interviewing them.

We are two crazy Koreans finding themselves in US with extremely tight budget. We eat $2.99 'Hungry Man' frozen food a meal to survive. But we have 25k passionate fans supporting us and soon we are going to open up our channel in China as well, to deliver our videos in Chinese subtitles, so if you are interested in Asian markets or build your user base there, we can help you.

Thank you. I look forward to seeing you guys soon!

Building Dreams: Insights on Becoming a Hardware CEO
Another crazy (or maybe not so much) theory: An ancient evil watches unsleeping, waiting in pooled darkness, beneath the picturesque dwellings of this unsuspecting town. Man was never supposed to venture into these forbidden depths, but the temptation of wealth and unlimited energy proved too strong. Now, the timeless horrors have been released…
Ask HN: What is something simple you would pay for if it existed?
In other words, what is something simple you are missing now?

It could be an app, a piece of hardware, a food, or anything else within the realm of simple and feasible - just not implemented yet.

Chances are it does exist already, but perhaps it has not been marketed aptly or the functionality is not up to par with what you think is minimally acceptable.
Holy cow!! I didn't read the whole thing, but going back, I thought it was just the author's very peculiar style of emphasis! Like writing comic-book style: (1)

As one of the commenters on the USNI site said, I didn't realize naval wargaming had fallen so far. It sounds as though games like Harpoon are not used at all anymore, at least not in a serious fashion.

I think Armstrong is being a little optimistic about the benefits, though. Top Navy brass has a history of showing disdain when creative junior officers bust the shit out of their tactics and doctrine.
I don't think violent revolt is quite necessary. We certainly seem to be seeing a non-violent revolt happening in the entertainment industry. People, unhappy with the way the music and movie industry have been trying to leverage their monopolistic power over certain franchises, have turned to non-violently pirating media, to the point that, for a lot of people, and many properties, the easiest mode of obtaining them is piracy.

Étienne de La Boétie wrote in one of his earliest writings 'Discourse on Voluntary Servitude"[0] that tyrants only have power because people voluntarily give it. All that the people must do to overthrow the tyrant is to just sit down on the ground and give up helping him, because the tyrant has no true power of his own.

One of the more reassuring aspects about the Internet and the global economy is that ideas can spread in an instant, and it really enables people to be able to freely associate, even in many cases despite their governments' express attempts to prevent them from doing so. I think the Internet is growing a sense of global community, where it's a lot harder for the average joe to think of someone on the other side of the planet as a faceless enemy, specifically because it puts a face on people.

And it also allows us to trade with so much more ease. It doesn't matter if it's in dollars or bitcoins or euros or whatever. Currency is whatever is convenient. And the technology we have today makes it incredibly more convenient than ever before.

So in sum total, I think it means that it's so much easier today to just ignore the tyrants and go about life in your own way, on your own terms. The more people do that, the less support the tyrants have, until they either capitulate to be able to capture at least some of the pie for themselves, or starve to death.

"You don't see how he hurt society and how much more wealth could have been created without his decision."

"Gates took wealth from the many, many people and gave it to the few."

Those two sentences do not mean the same thing.

Your argument, when you boil it down, is that Bill Gates kept wealth and power for himself and his company, instead of allowing others to have it.
