I have no idea if Apple was using Gorilla Glass on the back, nor did I know whether GG is harder or softer than sapphire. I'd assume softer, since it's just a glass, right?

http://www.corning.com/docs/specialtymaterials/pisheets/PI23... gives its Vickers hardness as 701 kgf/mm^2, which http://en.wikipedia.org/wiki/Mohs_scale_of_mineral_hardness#... would seem to place in the 5-6.5 range of the Mohs scale, nowhere close to 9. However, Vickers is a scale of resistance to plastic deformation, while Mohs is a (highly nonlinear!) scale of resistance to abrasion, so perhaps take that with a gram of potassium chloride.

Other random places suggest sapphire's Vickers hardness is around 1800-2200 kgf/mm^2, which is substantially harder than the number Corning's brochure gives for Gorilla Glass.

I've worked in the banking industry for five years. I've watched dozens of focus groups and seen countless quantitative research projects that mostly all indicate how extremely difficult it is to get people to leave their current bank. Even cash incentives ($100 to open a new Chase checking account, etc) don't seem to move the needle very much in terms of attracting people to switch. The reason features like Bill Pay are free to users--and actually cost banks $1+ per user/mo--is because it will make your relationship with a bank that much stickier and difficult to change. Photo check deposit only brings Simple to feature parity with other banks, almost all of which are using the same provider (Mitek or similar). This isn't to say Simple can't do really well attracting new customers; I just don't think they will be effective even in the medium term at convincing people with an existing banking relationship to completely leave their bank for Simple.

The answer is in the term "data warehousing" -- http://en.wikipedia.org/wiki/Data_warehouse -- which has implication that you're going to be doing data mining on vast amounts of data, often historical data like logs or transaction histories.

Google has systems like this for analyzing its request logs. Think of how many HTTP requests hit Google's front-end servers per second or hour or day. Each one has a few dozen pieces of data associated with it -- URL, client IP, headers, etc. Suppose I want to make a bar chart of how many requests came from France containing a certain header, each day for the last year. The system can do this query quickly if the requests are already bucketed by time interval, organized by column, compressed, and stored so that exactly the information needed can be brought into RAM quickly.

It is a little funny, when you step back, that "storing," "archiving," and "warehousing" are different things and Amazon has services for each. Try explaining the difference between S3, RDS, EBS, Glacier, and Redshift to a layperson.

The closest things i've seen are exploratory data visualization products such as tableau (which is pretty awesome). The downside (or partial downside) is it can end up writing some nasty non-performant queries in certain aspects.
I suppose the only real alternative, then, would be compete with them on the network effect.

Good luck.
Elon didn't directly address the advantage of the Skylon (he said he hadn't really looked into it, so fair enough). The main advantage is not that you don't need to bring oxygen for a portion of our trip (which as Mr. Musk points out wouldn't really save very much), but rather that you don't need to bring reaction mass.

Jet engines are just really really fast propellers. They don't need to carry their own reaction mass like a rocket. This gaves them a completely different efficiency profile (no reaction mass, means less weight, which means less fuel, which means less weight, rinse/repeat to the limit). This is the reason that 747s use jet engines rather than rockets. Being able to use both technologies fluidly within their optimal atmospheric envelopes would be a major breakthrough and would completely change access to space.

tl;dr Skylon can use a small, efficient jet engine to get high and fast enough that air resistance stops mattering and while slowly pivoting to a conventional rocket (which is optimal when the air gets thin).
I'm the original author of this article, and this is the most common feedback I've received for this. But the fact is, this article wasn't written for you, it was written for newbies.

If you have hung out in the RPi forums for any length of time you'll quickly see that there are a LOT of customers who who nothing about this device, or Linux for that matter. It was cool, so they bought it. There's nothing wrong with that, because they're willing to learn and that is the intended use of the product.

So yes, you and I both know that there are just a couple differences here and there but mostly it's just installing a webserver on a Debian machine. The ARM processor vs x86 is the biggest difference between this and the most common install and it doesn't factor in to the process anyway. You know this, and I know this but how about someone who knows little to nothing but wanted to get a pi to learn it?

My intention for this article was to help those people who are very new to this device and Linux, and it's been received well in that regard. They're very likely going to be looking for "how to _____ on a Raspberry Pi" and so that's what I'm going to give them. It's simply building a bridge to help get more people into this geeky little cult we live in and I don't see any harm in it.
More like geeks like to prove they've already heard of the idea behind something.

Dropping the name Betteridge or Dunning-Kruger or Godwin tells everyone "I heard about this phenomenon before it was cool and even know the name for it".

Basically a geeky way to be a hipster.
> I know you can send checks directly to recipients,

I wonder if these are "real" checks against your account, or just checks against some single account that Simple owns. Because if they are real checks, it would be simple enough to get your own checks printed up with the routing info.
I don't suggest taking "entertaining" as synonymous with "humorous." Non-fiction books, sad films, and football matches are all entertaining for some people. Entertain the HN audience by delivering the sort of thing they like - well considered insights and technical information.

Nor is the reference to timing implying comedic timing...except in a general sense of delivering your ideas when the audience is likely to be prepared in the right way to appreciate them. This fleshes out to when and where one comments - before HN became kinder, gentler, and larger, early snark on a rising thread was often worth a few points. Well considered comments on a recent popular thread will often do better than those delivered otherwise.

Timing requires understanding the audience or perhaps having a model of that portion you wish to reach. Writing for someone is a good first step toward being entertaining.
Bell Labs Computing Center Orientation video exactly what you'd expect
Think of bootstrap as a base, an alternative to the reset.css that everybody used to use. You can use as much or as little of it as possible. Everything that you haven't explicitly styled gets a sane default.

It also can be used as a specification for markup. The markup required for Bootstrap's form-horizontal is kind of ugly, but if everybody uses it than it becomes much easier to move form CSS from one project to another.
No, I didn't .. But I heard it has some glitches here and there.
> The bigger question for me is why Amazon has been able to figure out the technical details necessary to run this kind of service for this price.

I guess they grew the infrastructure for themselves, optimizing it bit by bit over the years. And then noticed that it could be sold too.
One would assume now that they are priced nearly identically.

This post epitomizes the threads running through arguments for and against a liberal arts education in the year 2012. On the one hand...

http://www.radiolab.org/2010/aug/09/

which will far better argue and illustrate myriad points on the invention of language, its beauty and wonder and value to differentiate us as a species and to bring us joy and fulfillment and illustrate the challenges and quirks that make its study such a joy and illustrate language's evolution as a thing of wonder.

Then again, you see something like the Rossetti archive

http://www.rossettiarchive.org/

and you are awe struck at the meticulous rigor and academic sensitivity it takes to understand permanence and context and format and physicality as intrinsic to the right of artistic expression.

Would these works have as much meaning if we OCR'd them, slapped them in times new roman, and beamed them to your twitching sweaty little palm sized cubes? Probably not.

It took a lot of time, a lot of arguing, a lot of hard questions and personal growth before I felt qualified to make statements like, "I don't think its a good idea to build a game engine that uses a Barthes-esque narrative decomposition to dynamically construct compelling storylines for video games." I don't think a religious education qualifies you as arbiter of language. I think his word is fun and quirky. Interesting. Highly relevant and timely.
I don't know anything about cabs, but the article makes it sound to me like we're talking about a $5 difference here. If you can afford $20 on a cab ride you can probably afford $25. We're not talking about the difference between millionaires and people living below the poverty line.

Class discrimination isn't great, but it's certainly better than race discrimination, insofar as it is possible to change your class (however difficult that may be) and not your race. It's a step.
Right, a CMS lets you implement an architecture for HTML and CSS, e.g. Bootstrap.

Huh?
Suppose that we start near the edge with a self-replicating probe that can spread outwards no faster than Voyager 1. In 2 billion years, every solar system in the Milky Way would be chock full of factories trying to expand.

And there is no need to assume that it is so slow. We have already designed technologies to send probes to stars much, much faster than Voyager 1. Here is one. Put a bunch of solar panels on Mercury, and use the power to shine a laser into space. That can push on a light sail, pushing the probe outwards at something like 1% of the speed of light. Then as it nears its star, let the sail fly away, shine the laser again, and have its reflected light brake the probe.

With this level of technology, which may be feasible for us in just a few hundred years, the colonization of an entire galaxy can be reduced to tens of millions of years.

If technological life is out there in our galaxy, in the blink of cosmic time finding evidence of it will not be a search for a needle in a haystack - it will be closer to finding a piece of straw in a haystack.
I admit I'm a bit confused because in Microsoft's own video on that page they highlight Google's text that says, "Payment is one of several factors used to rank these results"

Well, unless I'm missing something...no duh. Everyone knows that.
The reasoning you're using here about exposed attack surface and complexity is faulty. You are better off exposing a trivial interface with nginx or Apache than in giving someone SSH credentials.
Dito. This is a total show stopper. Only undoing your very last action and with no redo really sucks. I repeat that as it might sound like a joke to most people. There is no redo. And you can only undo one thing, where "one thing" might be typing a massive formula with all the correct mathematical notation or one full page of text.

So if you undo your last 5 minutes of work because you thought you would undo one line or something there is no way to get it back. T________T

If you deleting something inside that one thing you are currently typing, that deletion is also completely impossible to undo because if you do you will undo typing that entire block. (Undoing a small accidental delete is usually the cause of the scenario i described above)

You don't need to be an arbiter of language to find out what is and isn't a word. Damascean isn't a word. The word is Damascene. The phrase is Damascene conversion. Using the unword Damascean only harms the form and function of the prose.

How did this get on the front page?

- The headline is sensational (goes from "Django doesn't support NoSQL" to "Django is falling behind").

- Author says Django "claimed to be SQL-agnostic" then goes on to conclude that it isn't because it doesn't support NoSQL data housing. What? SQL-agnostic doesn't mean storage agnostic. It means /SQL/-agnostic.
At the core developer Q&A during DjangoCon US this year, it was pretty much universally agreed upon that non-relational database support for the core of your app was too much of an edge-case to bother finishing work on.

I used MongoDB for a year and a half. For 99% of projects that I see on HN and hear about IRL, I'm comfortable saying that you don't need that as your core database. Consider it for the portion of your domain that actually needs nonrel benefits (such as analytics), along with others like Couch, Redis, or Riak.

Your thinly-veiled CRUD app with a social layer doesn't need MongoDB. Here's a nickel, go use a real relational system like Postgres that makes sense for the meat of your data.

It seems Google's sole contribution to the PAAS wars is to keep Amazon's pricing in check. Does anyone here actually use Compute Engine? With Google's customer support story, I couldn't touch it with a barge pole.

Nobody is claiming that the Unix philosophy depends on objects. The author was trying to claim that applying some Unix principles to Object Oriented Programming would be beneficial.

The GitHub version and the version on the jstat website are vastly different. Just thought I'd point that out. I like the way that the GitHub version is laid out in a modular format.

It's not that I didn't take it kindly, it's just that I'm tired of the negativity on Reddit and I'm not afraid to say it. Too many times on there I see great content being downvoted and shat upon by a bunch of people looking their hardest to bury something just because it makes them happy in some sick way. If you post something for a beginner, many people there are quick to show off and act cool and fill it with negative comments and downvote it.

It's not just my content, in fact I hardly submit much there but I see it with a lot of good links in /new. I just think if your whole mission on Reddit is to find new posts and insult the OP and downvote everything that isn't posted by someone in the clique, you need to get outside more.

I typically use Mathematica to prototype ideas. When they pan out, I integrate them with existing code written in c or Python. That Mathematica excels at symbolic manipulation as well as numerical solutions while having excellent visualization tools makes it invaluable.

I have a "premiere" relationship and "personal banker" at my main bank, yet having used Simple for a year I'm actively evangelizing those I know to try Simple, and have switched to Simple for my everyday wallet. The Simple banking experience for what most people need is like the original iPhone was to 2006 era smartphones -- the "feature" list is not the real story.

Simple offers an extraordinarily low frustration factor between you and your goal, and this isn't captured by the "tech specs".
