I thought the whole reason NASA's shuttles jettisoned their rockets and large fuel tank was because getting that added weight in to space was prohibitive. How is it that they propose to get not only the entire rocket in to space but also enough fuel to provide a soft landing on re-entry of all 3 pieces? I realize rocket tech has come a long way since the Shuttle's design, but is it really that much further along?

I really do hope they can pull it off though!

Coaching Kids to Focus on Focus
tptacek, I like you, but in this particular case Josh really wasn't in the wrong. Definitely not a 'b school' kid; I went to high school with him (so I'm biased) but I can vouch for the fact that he got royally fucked over.
God I wish my team had a Hubot.
The extra reaction mass is just a balance between the various costs. Building a new rocket per launch vs some constant factor off the top of your payload capacity.
I agree with OstiaAntica. This Economist article is a thinly veiled call for more debt and more inflationary spending. Who stands in the way of "recovery" ? The obstinate Germans (who learned the lesson of hyperinflation last century) with the only sound Euro economy, i.e. they will be paying for the bailouts. In the USA its the Tea Party and the few Republicans with a spine who recognize that the problem is the massive debt and adding to it is only going to delay the inevitable and make it worse. The bold action (that will never happen) is to let the zombie banks and businesses fail, then pickup the pieces and start over. It won't happen and everyone had better prepare for high, if not, hyper-inflation because politically that is the road we are on.
You mean like a free market economy?
I'm trying to understand, google hasn't enabled native client on chromeos yet? And the chrome extension allows you to enable it for a specific site? Is that possible for any developer to do? That could be useful for a use case I have.
If we project even further chrome will have 200% market share, imagine the results of that!
We do give you basic information, like whether or not the CVC code and billing address match the credit card. We'll consider adding more information over time.
letting the banks fail, recapitalizing new banks, and basically rebooting the financial system

Please tell us how that works in practice rather than in theory. I really, really want to know how you just 'reboot' the financial system without massive disruption to retail banking or the payments system. How do you 're'capitalize a new bank? If you just mean create new banks, who is running these banks? I mean, I'd like to have seen a complete reboot of the system as well, but it looks like the sort of thing that is much easier said than actually done. If you're going to mention Sweden, provide specifics of how long it took and how much capital was involved.

We shouldn't practice financial regulation like it's holistic medicine. Metaphors about cleaning the pipes and taking the pain should be weighed against the evidence we have about what happens when you let banks fail, and that didn't go very well when we did it with Lehman Brothers.

Chrome without a doubt feels faster than Firefox to me. I think Firefox's performance has degraded over the past 6 months or so. I can't prove it (just anecdotal based on my experience), but it got so bad that I switched back to Chrome (and have been loving it).

Check whether your credit union participates in this: http://www.co-opfs.org/public/locators/ATMlocator/index.cfm

You can look for the logo on your ATM card.

I don't guarantee anything but you might be surprised. In fact if you already belong to a credit union you might be very surprised. Check for the logo on your card. I belong to a credit union tied to a university that I've since moved about 2 hours away from, and except for loans (which I do so infrequently I don't mind driving for that, there's a full branch about an hour away) I've got plenty of ATM coverage everywhere I go.

> It's not at all clear to me that the end effect is as different as the proponents claim.

There have been studies (arXiv used to link to them, maybe still does) that show that open access substantially increases the number of citations a paper receives. That strongly suggests that open access works better for distributing research even within the academy, which is just common sense — open-access papers are easier to discuss, find links to on Reddit and Wikipedia, and often simply obtain. Outside the academy, where it's even harder to measure readership, we can expect the effect to be much more extreme, since most people outside the academy actually have to pay to read non-open-access papers.
If you are looking for a technical solution you might want to check out..ahem... my company ThreatMetrix.

As ex paypal Im guessing you have invested a lot in risk management, ML and automation etc as its really technically difficult to make such a broken process like online payments this simple so you may have it all covered.

What we can bring to the table is a (300ms) https name value pair API that delivers aggregated intelligence in real-time based on transactions, identities, devices and behavior across 6000 sites that represent over 1MM individual CNP txns on a daily basis (only 1/5 of Paypals txns but hey we are a startup!) which you can ingest into your rules engine or risk models during, before or after the payments authorization/capture.

We dont just provide a score which can be impossible to integrate with other ML engines we also provide customizable (by you) reason codes/triggers that can be used to characterize behavior e.g. customer's computer associated with 3 difference identities and 4 different proxy ip addresses across global network in last hour....Data Geeks geek out on it as we also provide full attribute data back in the API response so provides a good way to do feature extractions for SVMs etc. We have been proven to reduce FP and increase TP.

We currently process peak 700 tps with about 20% degradation in performance at load. We suck at batch processing cause its just not our thing. I head up products and one of the founders so not selling just helping as I think you have a solid offering that should do very well.

Paypal bought Fraud Sciences for 170M but you can rent ThreatMetrix ;-)

White Stretch Marks
It can be done. Up until 2005 Denmark's government-regulated debit card network called Dankort was completely free of fees.

Eventually the banks lobbied the government to allow per-transaction fees to be charged for use of the card, but after only a few months of that practice there was so much protest among consumers that the per-transaction fee was converted into a fixed annual fee.

I've even been delegated a review by a researcher at a different research institution. (He didn't feel like he knew enough to properly review the paper.)

While this is fine for the home tinkerer, an ATX power supply doesn't provide any of the basic safety features that are one of the main points of a professional lab power supply: protection against over-voltage and over-current. You really don't want your power supply to be damaged by a faulty circuit. And who knows how clean the power is.

Most people who have a use for a bench supply should also be able to figure out how to make this box for $2 instead of $45.
LUCID does look cool. Thanks for the tip!

you're right, "avoiding your customers" is not a scalable long-term solution for deployment. As businesses, big or small become more global this will become a bigger problem. As I'm sitting here reading this I see a potential for new business. We need to find some way to filter traffic. Think about two different versions of the website existing at the same address and in front of the website sits a fork (like a fork in the road) that splits incoming traffic into two groups. As traffic comes in a portion, say 20% is then the diverted to your brand-new deployment while the rest, 80% is directed to your older site. It's almost like having an semi-open beta in regards to the new deployment. It will be tested in real time under real circumstances. Then as bugs get ironed out you can increase the ratio from 80 – 20 gradually until all traffic is now being fed into the brand-new live site.
so who wants to co-found this with me? we might be able to make it in time for the next round of Y Combinator!

by the way I didn't think you were saying that you should deploy during your busiest time, I just met all things being equal, the should definitely look for "off-peak" times to rollout new deployments. But we both seem to agree that the long-term solution. Globalization is going to make off-peak times a thing of the past. Hence see my solution above, we can get ahead of it and make some money.

No.

Researchers at universities invariably do academic work for conferences, for journals, and for other universities — giving talks, for example. Often they get paid directly for these. This is a fundamental part of how academia works, and has been (in various forms) for centuries.

I worked in Silicon Valley as a sysadmin and programmer in 1996-97 and 2000-2006, at a total of seven different companies. I've also worked professionally at a professional services company, a defense contractor, and freelance for various clients (primarily in the US). I don't think I've ever seen an employment contract that purported to prohibit me from "doing professional work not associated with [my] current job". In some cases I have proposed modifications to confidentiality agreements with the explicit purpose of ensuring that I could moonlight safely (for previous clients, normally). The modifications were accepted.

And I don't see how it's possible for them to proxy SSL content without being MITM and re-encrypting. They could stay entirely out of the way for HTTPS requests, but if that's how they were doing it, I think their FAQ answer would just say so. If, on the other hand, they're inline enough to do the Silk acceleration thing at all, they have to be able to decrypt the traffic.
Pretty bad post if you ask me.... these generic "top business tools" articles are a dime a dozen and this one doesn't even mention anything new and even leaves out some of the better tools.

I always thought the real goal of Google Analytics was to upsell me into using Adwords, and to prove once and for all that there's no point in optimizing for any search engine except for google.
Hmm, well, but it's interesting that the US went down that road and built an unreliable "reusable" spacecraft that had a high failure rate and had be largely reconditioned at high expense after every flight. Meanwhile, the Russians are using an incrementally improved capsule design from the '60s that's simpler, cheaper, and safer.

I'm not saying that a true reusable speacecraft wouldn't be revolutionary. And maybe it's possible with '10s tech in a way that it wasn't in the '70s. But picking "reusable" as a goal in and of itself, rather than using metrics like reliability or cost per pound to orbit, seems like a dodgy business.
When you hear of Las Vegas what would you have in your mind?

There are some advantages of double quotes like you don't have to close quotes every time you use variable. But I prefer singles because its cleaner and it helps me read my own code better.

Ask HN: Possible to get hacker input for a for-profit project?
Hi HN,

I am learning how to code at a feverish pace. I have a new idea every week. So instead of going out and looking for a technical co-founder, I decided sometime ago to get technical myself. Really glad I made that choice. I am good at opening doors, calling people, getting meetings, and excellent at raising money. :-) The only part missing was coding, and I am on it like it's going out of style.

So far I've looked at tutorials for HTML5, CSS, AJAX, and jQuery; it all seems easy enough (on-line tutorials - built nothing yet). I am currently head-first in Rails (and really enjoying it - its way better than my day-job). However, I know I am learning fast, and whatever I build will not be world-class. Actually, it might suck a little, or even a lot, will even be slow and/or buggy. I want to make money from what I build. I enjoy programming, but I also like money.

So I was thinking, if I build something that is not optimally designed, would I be able to put is somewhere online, where other developers would be able to look at the source code, comment on my work, fix my mistakes or recommend fixes, optimize my code, or provide any other kind of input? I want to be able to chip in too, and learn from what people are doing to my code and saying about it.

Is there a way I could do that in a for-profit model?
I love the way you're running github.. deep appreciate. Please keep posting as it grows, so we can learn. Many thanks.
I agree that Aaron Swartz's actions have brought more attention to the issues, but I think MIT would object to you calling him "that MIT guy", since he was a fellow at Harvard, not MIT, at the time that he allegedly stuck his laptop in MIT's wiring closet; and the Institute has apparently at least cooperated in his prosecution, if not actively encouraged it.
Whatever language you learn there is only one way to be better coder that is coding lots of coding
The bank likely won't care if you use your card with a PIN ("PIN debit") or with a signature ("Signature debit"), which you refer to as "processed as credit". Either way, they still know it's your debit card that was used even though PIN and Signature debit transactions arrive at the bank through separate networks, so you'll probably get hosed with the fee unless you're in one of their "premium" accounts.

Community banks and credit unions everywhere are licking their chops at the opportunity to siphon off disgruntled customers.
Ask HN: What is a good tutorial (like codecademy.com) for learning HTML?
I am trying to find a tutorial for people who haven't a clue what HTML is. I need to be able to give them the site and know that they are learning up to date HTML (unlike if I gave them w3schools) tutorial that would teach them the basics of HTML - basic syntax. These people know absolutely nothing about web development let alone programming. I think Codecademy is top notch for Javascript, but am trying to find a good one for HTML.

Any ideas?
I'm hoping that the materials are finally here to usher in the next generation of space vehicles, because this idea wasn't nearly as plausible back in the 60's.
They aren't hardly at the scale of Lehman/BoA though - its hard to imagine a failure of one of those banks being handled by the FDIC with anything approaching grace or control.

While the greater point may be true, it does have the benefit of hindsight to a certain degree.

At the same time - after seeing the effects of Lehman's collapse, the regulators really didn't have any other choice than saving those banks. The option of not acting really wasn't there.
Not exactly. True free market economies would let the banks fail, but the government also wouldn't recapitalize new ones, it would let the market handle that, or not as the case may be.
As others pointed out, that is at odds with the previous paragraph ("We will establish a secure connection from the cloud to the site owner on your behalf").

Also, unless they stop doing the Silk combining thing entirely, I don't see how it's possible not to peer inside the requests. They can either pass along the traffic without knowing what it is (meaning they can't cache, or combine, requests or responses, because they don't know what's in those requests and responses), or they have to see inside.

This, to me, means they're taking liberties with the meaning of "direct connection" in the snippet you quoted, and, if I'm being pedantic, I don't see how the final sentence ("Any security provided ... would still exist") is literally true at all. Seems to me that being end to end, encrypted by a key only you and the other end, know, is a form of security that does not still exist in this architecture.

(Somewhat off topic, but when using earlier-generation Kindles with whispernet 3G, over 3G, all traffic is proxied through Amazon's datacenters, even for SSL, and I have no idea if it's secured end-to-end all the way to the device, or decrypted in Amazon's datacenter, and possibly re-encrypted to send OTA to the device. There's no way to tell.)
Is that in writing anywhere? The USAA website suggests otherwise.

https://www.usaa.com/inet/pages/pub_eligibility_task_entry

Who is eligible?

Active, retired and honorably separated officers and enlisted personnel of the U.S. military.

Officer candidates in commissioning programs (Academy, ROTC, OCS/OTS).

Adult children whose eligible parents have or had a USAA auto or property insurance product.

Widows and widowers of USAA members who have or had a USAA auto or property insurance policy.

There are other ways to get in, but it is still via (sometimes indirectly) the military. Occasionally they open it up to employees of various government agencies. You can also get in if your spouse is a member. My wife was previously married to a member of the military and got in that way. I got in when she married me.

USAA is awesome. If I didn't have them I'd probably look into BankSimple.
