Having written code to interface with the IBM mainframes that power the credit networks... yes, I'm pessimistic about this. I absolutely welcome any improvement in the payment card space (especially around authentication and security in general) but so long as they're going over the existing networks at any point, that's going to be the weak link in the chain.

Simply put, it's a really bad chicken-and-egg problem. But offering a traditional payment card to bridge the gap does nothing to improve retailer adoption of the necessary tech to really move things forward.

Unless google is going to provide (and replace) that hardware, it's unlikely to happen. And if they do, they basically have to declare war on Visa et al due to the PCI requirements around POS hardware - they're not going to certify hardware that can be used to eventually bypass them, and merchants won't risk using uncertified hardware because they'll get shut off by their acquiring bank.
Thanks Saurabh. Pleasantly surprised to find you here :).

I find that to be a very reasonable cause of concern.
Do we really need to coin the phrase "hacker privilege?"

Look, I know it sucked in school, being ostracized for having technical interests, but now you're grown-up and loaded. As part of a larger social agenda, I can see some harm in perpetuating these geek stereotypes, but on a personal level, you are not being exploited, so quit whining.
>The gas infrastructure has already been built.

And it works very well: for gasoline. Hydrogen cannot be contained in a rubber hose. Ammonia will eat away copper pipes (see http://encyclopedia.airliquide.com/Encyclopedia.asp?GasID=2#... ). CNG works fine, under pressure, which requires retrofitting everything, but natural gas is a fossil fuel. Biofuels come with a whole host of other problems.

The simple fact is, whatever we use, we're going to have to rebuild stuff. There's no way to reuse the gas infrastructure for any fuel that isn't a non-oxidizing hydrophobic liquid, which rules out approximately everything. Hydrogen fueling stations aren't retrofitted gas stations: they're a totally new thing:

http://en.wikipedia.org/wiki/Hydrogen_fuel_station#Hydrogen_...

>However, this does not begin to replace the existing extensive gasoline fuel station infrastructure, which would cost a half trillion U.S. dollars in the United States alone.

This is not cheap.
Beautiful, wish I had a Dribbble account too so I could rebound this babe.

Does HN need a redesign? Not really in my opinion, but a subtle facelift would be alright.

This is insane. That's why I use the https://mypermissions.com plugin, so these types of things do happen to my Facebook...
>Unless google is going to provide (and replace) that hardware

Mm, I had thought about the same thing. They could too, they could have some secure NFC smartcard and a contactful NFC card and use PKI and on and on, if you work in this area I'm sure my ideas pale in comparison to what you work with or can imagine.

I think they have to declare war on VISA. VISA doesn't seem to really give a shit to bother improving and it's probably in their best interest to keep everyone hooked on their physical infrastructure. If your phone becomes the focal point of the POS system, then I would imagine payment processor competition would be encouraged. I'm more or less just yammering now though, sorry.
For used cars, gumtree is the business. I just sold a used car on there and had several times the response I did from the same ad on carsales.com.au, which cost $60, was much harder to use and so was basically poor value for money.
All they need to do is add a new "message" to say "y'know that message number 4029375 in the cache, yeah that ones deleted, ignore it".

This is not hard.
I don't think that's accurate as of a week or two ago.

Er, actually, I think that's just for online purchases. Google Wallet in the past has used a Masterpaid prepaid card for NFC transactions and my understanding was that the recent update causes a more direct credit card emulation as it will allow to use any sort of VISA/whatever.

It's been such a great game, I lost countless hours as well.

They redid the original Goldeneye for Wii and sadly I bought it. It's a horrible remake. Aiming with pointing using the Wii Remote is really hard and turning around takes ages, but this isn't the worst thing. They changed the multiplayer game mode: You can't pick up other weapons as you could in the 64 version - you have to chose in the beginning which weapons you'd like...
I always loved this in the 64 version (proximity mines..oh yes :D)

Hi, a couple of suggestions here:
1. Landing page. It is not very clear for me what is the basic "free" course. Will I be able to go all the way up to building my app with the free one? If you write it as Course 1: RoR Basics, you lead me to think you will only tell me how to define variables and then try to charge me for it.
If the case is that you can build all the first app for free, I would change the wording to: Course 1: Your first app, or something like that.

2. Once I click on take the course, you redirect me to a page where I only find text. Wait...this is not what I wanted...bail.
I think that once you redirect, the first thing you should see is the course (or the console), so you can start exploring and falling in love with RoR.

3. There is way too much content in that second page...it feels more like a blog post. I would put a link to that content in the main page under three small links: Why codelearn? Why Ruby on Rails? Do I need Ruby? or something like that.

4. Most important: Why is all the scary code in the first class? If I am a newbie and I see that, I would think its way to complicated! Start with something easy...there is a reason why "Hello World" is the first thing you learn in any language out there.

5. Also, I cannot try the things as a anonymous user (I don't know about registered ones), because the console is nowhere in the page!

Good luck guys, I wish you the best.
Who is "we", btw?
Who is ready to see Facebook fall?
It doesn't give a shit about it's users. It was foolishly founded without a business model and still doesn't have one. It is a gigantic failure to it's shareholders (aside from the initial investors of course). It was founded by a shady thief. The world is enamoured with it and at the same time prone to being reliant on it.

Seriously why is Facebook relevant? It was a nice experience while it lasted but it's turned to crap. It's time for a real, decentralized, pro-privacy social network to take precedent.
I agree. Some of the images are plain wrong actually. They show screenshot of older version of Codelearn Playground. We will fix them.
I think you're talking about different issues. I read it as a practical communication issue more than a visibility issue. If people are getting stuff done, but not telling anyone that they're getting stuff done, it creates an atmosphere where people don't think stuff is getting done, and that's just needless stress.

I've been guilty of this as well, and although for the most part everyone knows I get stuff done, it does create uncertainty about where our project stands. It's hard to remove the air of "we're fucked," and that's especially tragic if by all objective standards you're doing fine.
And I didn’t say he or she would.
Point 1 & 2 taken. I agree to your observation. The user should be shown 'Aha' moment ASAP & we are only delaying it which is bad.

Point 3 - guess this is classic example of we founders trying to show the philosophy as the first thing to the user. While he/she wants to learn RoR. Guess we should create a separate link 'Philosophy' on the main page & link the content there. Something like https://supportbee.com/ .

Point 4 - guess the command out is too long (especially the rails new part) which is making it look long.

Point 5 - a linux user is needed at the backend & hence there is a signup process for that. We need to figure out a sub-optimal way to provide console access to non-signed up users as well like what Codecademy etc do on their main page.
This isn't a case of eventual consistency. They don't bother to update the cache(if that is the reason) or update the database used in newsfeed. The deleted posts persist in the newsfeed database many hours(maybe forever) after the delete event.
It's possible, given time, for a weak programmer to become a solid programmer, but the programmer has to 1) recognize that they're a weak programmer 2) want to improve their programming ability and 3) be part of an organization that allows them to do so.

From what I've seen of government bureaucracies and the sort of people they attract, I'd be willing to suggest that none of those things (especially (3)) will be generally true of this new organization.

Optical illusions where we see one thing then another are numerous, e.g. https://en.wikipedia.org/wiki/Rubin_vase

In these there is obviously some contest going on between fuzzy classifiers, as there is in conceptual association games, misinterpretations of song lyrics between people and errors like the Freudian slip. There are at least large parts of our brains that seem to operate in this manner.

That said our use of logic and reason certainly says there is a part of our brain that works in a non-fuzzy way, or at least can be trained to work like. However, while there are people who understand the odds and are just there for a good time, it's instructive to go to a Casino and see how many people believe they can win and believe in lucky charms.

This topic is a minefield of semantic games with hidden assumptions and people arguing across each other though.
EV's certainly haven't already won, but I do think there are many cases where they're (almost) perfect.

For the person/business who doesn't drive far and can plug it in at home/work, they've now saved a detour to the petrol station. I'd love that. I suspect many businesses that have delivery cars within a city could make that work, assuming all the other costs lined up.

I think making batteries portable is very possible, but it'll take a generation or three to get that right, assuming the above market segments are saturated and Tesla sales are limited by this issue.

What remains a problem for me are the lifetime of batteries, and the need to drive outside of coverage areas. I like to drive cars for a while rather than replace them often, so don't like the idea of replacing a large part of the cost. And I don't want to worry about charging stations when going on holiday. But again, for a city-based business that replaces cars more quickly than the batteries would last, those issues might not be relevant.

One strong driver for innovation is that battery technology would become important to (at least) both the IT and auto industries. Research and innovation would accelerate and be useful to both industries via cross-pollination.
I don't particularly have any reason to believe one way or the other. Certainly, the probabilistic models for language are created "out of the blue" without any attempt to model how human learn languages.

I beg to differ:

> The Tesla Model S is a great-looking car but, unlike some, I still don't see electric cars as being the future.

The comment is arguing that electric cars are not the future because batteries and energy delivery and what not is not ready now. Guess what, now is not the future. It would be like arguing that ICE cars were not the future in the 19th century.
I'm impressed. I definitely thought it was hyperbole when Joel said they would carry the fuel if they have to.

The reason for having better support for C/C++ is that you shouldn't force developers to use tools that they would rather not.

Not perl though, That'd just be sadistic.

"I claim that's BS. they're totally caused by money."

I disagree. The best hackers I know HATE working for the gobertment, because they hate working for "the man", or any bureaucratic organization, and gob is the definition of bureaucracy. Being told constantly what to do, no freedom, and stupid political bosses is the main reason, not money.
I think you mean human behavior is fuzzy. Brain circuits are sometimes chaotic but pretty deterministic. The sensory input is noisy though.

I'm most excited about the idea of automatic Client Bindings. I've been thinking about how cool it would be if you could dynamically generate a Ruby gem for your REST API, as well as a documentation site.
There's already grape (https://github.com/intridea/grape) and grape_doc, so it looks like 'grape_client' is the only missing piece. Imagine being able to automatically generate versioned client libraries for ruby, php, iOS, android, etc.

Would be super awesome if emergentone could get behind an open source project like that.

Oh hey, I just saw this now.

For what it's worth I thought you were from Mozilla when I wrote my post, not that it matters that much either way.

I think you made some substantial points that were not covered in Brendan's slides, specifically:

- A standard with only one implementation is de facto controlled by one entity. This is a great point, and different than Brendan's point "defined by implementation." Brendan's criticism would be solved simply by standardizing (P)NaCl under multi-party governance, which I fully expect Google will do at some point. [0] Your criticism is not solved unless it is actually practically feasible for someone else to implement that standard.

- Relying on binary-level validation of binary code has a lot of attack surface. This is a great point that I've seen others make, though I believe it is being addressed (perhaps since you wrote your message) by having multiple layers of defense (ie. also running in a separate process inside a ptrace sandbox).

It doesn't bother me that you joke around with your friends by calling it "ActiveG," because in the context of serious discussion you acknowledge that it has "a better attempt at security design than ActiveX." It does bother me when others seriously compare the two, as if a completely unsandboxed execution environment can be compared to a serious attempt at sandboxing.

In any case, now that it supposed to be shipping soon (http://news.cnet.com/8301-1023_3-57534803-93/google-offers-l...) we should get a better chance to see if it truly can demonstrate a compelling improvement over JavaScript.

[0] Just wanted to mention that though I work for Google I am not involved in (P)NaCl and have no inside information about it.
Actually, that's more accurate.
