Indeed. I like the non visible UI. Almost Brett Victorian.
I once got to see a federal judge tear a plaintiff's lawyer a new one. I sat through the whole trial, and up until the judge was mid-way through his ruling, I had no idea which way he was going to rule. But suddenly I realized, despite the measured prose of the decision and the unraised voice reading it, that the judge was pissed. He felt the whole thing was a giant waste of time, and that any lawyer who wasn't a complete fuckup would have kept the case from turning up in his courtroom. And it wasn't just me that realized it; we all watched the plaintiff's lawyer slowly wilt.

It was an incredible thing to watch. The formality of the occasion, the power of the judge, the power of the system he represented, the normal range of courtroom expression: they all set a context in which a slightly raised eyebrow was more powerful than the loudest shout, that arch deprecation was more cutting than a raft of verbal abuse.

I expect it's the same deal here. These are US Senators asking, and they're basically, in polite language, making direct accusations of lying to the Supreme Court. I suspect that they, mindful of the co-equal status of the government branches, very rarely say things like this. So when they do, everybody knows that they mean it.
I'm wondering if it's ethical to spread the word about someone who didn't pay you back. I mean, obviously the another one wasn't ethical, but are you allowed when he/she wasn't?

PS: Surely I'll not post on HN another history of someone who didn't pay me, I'm trying to know the ethics implicit on this scenario.
>This is just not true for many currencies that have undergone hyper-inflation and hyper-deflation.

This is true. But generally speaking, people go quite a bit out of their way to use currencies that are perceived to have a predictable future value.

This is why the dollar (and the Euro) is so popular the world over; it's value is pretty predictable, compared to most other commodities.
Gold is a physical good with actual useful value. It is hugely overvalued right now, and anyone telling you to "buy gold" usually holds gold and benefits a lot from that.

Those cable "invest in gold" deals are exactly this but worse - they sell you gold more expensive then the commercial market that can never be redeemed for that price.

But it has a real cost of production that represents its relative industrial worth.

Bitcoin is valueless though. Created Bitcoins do not have any industrial value - you can't use them for anything else, even though they have a cost to create. There's no reason, if they lose value, for anyone to buy them from you - whereas with gold if you sit on it long enough, it will become valuable when someone needs gold for some type of industry at minimum.
I doubt you can pay your house with gold bars alone.

I doubt you can pay your car with stocks alone.

I doubt you can pay taxes with option derivatives alone.

I doubt a lot of people call those funny money.
Does this mean as much as I think it does? Aren't most of our current cryptography schemes based on prime numbers taking time to calculate?
I suspect your sliding door will be made of multi pane glass filled with argon. that probably won't work too well. in order for total internal reflection to work well the glass needs to be pretty homogeneous, so that the wave fronts are all parallel. that requires a nice straight, flat, unscratched surface and uniform refractive index. hence sapphire.

also, he uses thick glass so as to catch the led light. since power leds don't distribute their power very narrowly, it will be tricky to get a large fraction to start transmitting down a thin plate of glass.

it could be made to work but it just will be harder / not as good.
He is European-born but has lived in Australia for some time now.
I liked the videos, but it think it would be even better to show someone actually playing it, ie. actually see the players fingers interact with game. Without this, it's sort of hard to get a handle on what the actual game mechanics are (unless that's the point and you want people to go and download to find out for themselves??)
The base64-encoded SSL certificate for *.ycombinator.com is 1,755 characters. Maybe there are a few savants in the world who are capable of memorizing that, but for the overwhelming majority of human beings, it's never going to happen.
> Deflation in a currency is not a deal breaker.

Its pretty much a deal breaker in the use of currency as a the general medium of exchange and pricing. Its not a deal breaker in its use as a store of value, obviously, but that's more about being an investment vehicle than a currency.

> As the currency stabilizes and more and more use cases emerge

What I'm missing here is any explanation of why we should expect bitcoin volatility to stabilize.
Deferral will look much better than a semester where you failed everything because you were working, and deferring to spend time seriously working on a product will be a net benefit anyway. Think of deferring to work on a product as being like a semester off to take an internship - remember how popular waterloo grads are these days? That is in large part because they spend so much time in internships/co-ops.
"it won't put food in your table anytime soon without you having to pay a good % in fees to convert it to real currency"

False. Last summer, I ate at EVR, a bar/restaurant in New York City accepting Bitcoin. I paid in bitcoins and their processor (BitPay) only charged a 1% fee.

Fees from Bitcoin payment processors are actually quite good compared to credit card fees.
Abuse? Yes. potential abuse is not, however.
Thank you! Is there documentation related to using sentinel?
Imo the end is quite dangerous, and in many cases ends up being incorrect. It's the classic view of: I'll put on blinders and not worry about the consequences of my actions now, because I need to ruthlessly push forward so I can get into a position where I can do good for society... later. But often later never comes.
This certainly puts Steve Jobs tradition of leasing a new car every 6 months to avoid having to put a license plate on his car in a new light.

The fact that mathematicians have refined the theoretical distance between pairs of primes has precisely no effect on the difficulty of factoring large composites. Those are completely unrelated problems.
> Why is that horseshit?

Because historically (and also legally) the bounds between what is private and public have been defined by what was plausible at the time, not by what was hypothetically possible.

We know live in a world were what used to a be a hypothetical dream (or science fiction novel) has now become the mundane. The law can either adapt (via judicial rulings), be changed by voters or become an absurd anachronism that's good for nothing but justifying invasive surveillance.

You're missing the point that all kinds of symbolic wealth can be easily converted into other kinds of symbolic wealth. If this weren't true, it wouldn't be symbolic wealth.
I only upvoted this because McMillen wrote it.
If developers are incentives by the possibility of winning $1m, they would start working months in advance. That's why it's not ok to offer $1m as a hackathon prize, as it's not in the spirit of hacking.
> This is just not true for many currencies that have undergone hyper-inflation and hyper-deflation.

When that happens, people tend to abandon them as currencies (though a currency undergoing hyperdeflation would be hoarded as a store of value).
Obligatory http://boilerroom.tv shoutout.

No salivating VCs, no cutesy avatars, the redesigned site is nice but nothing exceptional, and for some reason I doubt they even consider themselves a "technology company"—but they nail all the important bits. Great acts, frequent events, live audiences provide effective WoM and a sense of exclusivity for those who attend, and perhaps most importantly, everything's available on YouTube[0] and Soundcloud[1] in perpetuity.

What were your thoughts on the pricing model? I'm developing a game myself now and the way it seems things are going is freemium with IAP purchases. Why did you choose the 0.99/2.99? It's a tough choice to make
The prospect of a $1M prize wasn't announced until Oct 25th: http://thenextweb.com/insider/2013/10/25/salesforce-offering...
No.

If someone discovers a shortcut in factoring very large numbers, then it will have the attention of cryptographers.
Rushed and misread your comment, apologizes.
There's a reasonable expectation to have to demonstrate one's skills in an interview. Whether any given test or set of questions actually is valid for doing that is another matter entirely.

Put another way: it's just as unreasonable for a company to expect a developer's skills to be measured by contrived tests or to demand they spend any unpaid time at all doing "work" (e.g. projects), as it is for a candidate to expect a company to effectively kiss his butt and lay out red carpet just because he decided to apply.
This is why educators get crap wages despite having a union -- because they refuse (rightly or wrongly) to allow the student's education to suffer by striking.

Which means their strikes are never effective.
What this article doesn't mention is that this data isn't only for cops, anyone should be able to see license plate records. Milage may vary, but since this is government data, something along the lines of a FOIA request should get you huge files with license plates, coordinates, and times. Some police departments may be more stubborn, but under current laws this data should pretty much be public.

For example here's data from Minneapolis (with anonymized license plates): https://github.com/johnschrom/Minneapolis-ALPR-Data

Privacy concerns aside, there's definitely something really cool about so much data.
I hope their kitchen is well-staffed if we're all going to start eating there.
Yes. It is, after all, Salesforce.
I can't quite tell if you are trolling me, but I'll assume for the best as I am truly curious on this.

To take your analogy the torch will loose battery at the same rate but with the plants leaves receiving more light it would be less light that goes in the face of the person standing behind the plant. Do the plants absorbing radiation lead to less radiation being around to be absorbed by humans and animals instead? Maybe I am fundamentally misunderstanding something here.
> I don't expect that there ever will be a perfect or optimal programming language.

I agree for the present, because of (among other things) the degree to which modern programming languages contain explicit references to particular hardware limitations and problems. The fact that resources are drawn from stack, heap and mechanical storage device, and the existence of rules for choosing which is appropriate, only tells us how primitive modern languages are.

Mathematics might stand as a counterexample (of a universal language) if it were easier to use for programming -- but that problem is being addressed, and computer languages become more like mathematics as time passes.
Wow that was one of the most informative interviews I've ever seen.

Oddly, none of that brought me any closer to understanding why he's crossing the picket line. I can visualize a prof on the other side of the line writing the same thing. (hopefully a prof somewhat more fond of brevity)

Good choice of projects. Every age sucks for something, the fun comes in being able to do the cool stuff, looks like you found that.
> minimum income like in Switzerland.

Switzerland has adopted a basic income, not a minimum income. They are two very different policies (minimum income pays the difference between the minimum and the actual outside income to those whose actual outside income is less than the minimum, basic income pays everyone the basic income, irrespective of outside income.)
You don't know what you are talking about. Just so you get the point I am going to repeat myself, you don't have a clue of the situation if you think that the story is anything other than the Baltimore City Council erecting regulatory barriers to FIOS in Baltimore City. Yeah, they might call it a "business move" now but the unstated fact is that it isn't worth it to Verizon to pay the city for a license.
What is the legality of something like this? If this worked or if it didn't and someone gave a damn it seems like this could fall under attempted destruction of property or something like that. I'm definitely not a lawyer though.
This stage of BTC growth is lovely. If you have a lot of it, you can issue transactions that might increase the total value. Not claiming this was the aim here, but certainly an effect :)

If this same owner splits the holdings up slowly, transfer wallets, and then recombine it again, it might spike up once more. People will definitely catch on, but it might bring up the value a couple hundred dollars in the hype.

Might make millions in the confusion.
Checks and balances are alive and well. No system of governance will prevent an action if everyone in that system supports it, nor should it.

We are the problem, we keep electing people who support this crap.
It would be cooler if it can be flipped back to the audience.
So, a bit of a rant, I dislike the current game culture meme of "this engine is poorly optimized". I am tired of seeing the following statement: game x is poorly optimized because game y runs better on my box. This is akin to saying: I find apples delicious, Oranges are terrible. Get apples noobs.

I would argue that the fact that you can drop in any one of a half dozen solid engines based on your programming language of choice speaks to the fact that they are commodities. At this point, for the vast majority of cases, it makes as much sense to write a 3d game engine as it does to write your own web server.

You can do it, but you could spend the time doing something that directly relates to the product you want to sell instead.
There's proof of these allegations- they apparently demo'd the app at a Salesforce meetup several weeks before the competition started.

See- http://www.meetup.com/Salesforce-com-Integration-Analytics/e...

So maybe, since you have this personal relationship with them, you can get the developers to come here and explain how that happened?
FossFactory has no fee, FreedomSponsors is 3%. There were some others but I can't recall them.
I think you could offer 1million but it has to be a competition where the teams that enter solve a single problem. That way accurate scoring metrics can be developed and used.

It doesn't make sense to say "Hackathon, 1 million dollars, Go!".

No.

Finding random primes is easy, especially if you don't mind using methods which allow an extremely tiny probability of error [1] -- this is standard practice in cryptography.

Finding random big primes p and q is easy. Multiplying them together into a product r = pq is easy. RSA cryptosystem picks p and q when generating the key, multiplies them, then throws away original p and q values. Only r is stored in the key.

Cracking the RSA algorithm itself [2] is basically equivalent to turning r back into p and q.

RSA is based on the hardness of factoring an integer into a product of primes. I don't think this conjecture will lead to practical improvements in cryptography / cryptanalysis, at least not with respect to cryptosystems that are currently widely used.

[1] http://en.wikipedia.org/wiki/Primality_testing#Probabilistic...

[2] Of course, there are many more attack vectors on specific implementations of the RSA algorithm, like trying to gain information on the secret key by measuring time taken to encrypt a message, measuring heat/power consumption/electronic noise, taking advantage of implementations that use a poor source of randomness, hacking into the system where the private key is stored, or bribing/threatening a human with legitimate access to the private key (as covered in http://xkcd.com/538/).
Hah Salesforce - you were better off having no hackathon at all. This is disgusting. Preselecting winners possibly?, not looking at everyone's app / video, selecting a winner that started way before hackathon was announced. yep total mess.
I'm surprised that people can be this naive.

They don't need to actually trace your money, they just need to know if you have more money than you reported as income.

This is called "tax evasion" and the IRS catches people doing much more complicated things than bitcoin every day.
The public key behind an address is only revealed if you do a transaction to spend the bitcoins in that address. So the public key is effectively secret until just before it is scrapped with normal use.
> $106 million out of $37 billion is 0.28%. Hardly "severe".

And yet they prosecute bank robbers and tax cheats, who steal a much smaller percentage of the mass wealth represented by banks and governments respectively, than do click fraudsters. It's not a matter of percentages, but whether the problem can be solved or alleviated. If no one acts against cheaters, people lose trust in the system.

Can you tell the difference between a secure hardware token and a fake secure hardware token?

I suppose if you try to extract the secret key and the token destroys it, it's pretty secure. Of course, you just lost all your money. I can't think of a non-destructive test.
Did you know about GCC's --help=CLASS syntax, like --help=warnings ? I didn't either, but your post motivated me to look it up. That's a bit like what you'd want--help only for specific types of things--but it has some bizarre aspects, such as no apparent CLASS defined by operation [-c|-S|-E], so there is still no obvious way to know from the docs that the only option relevant with -E is -D (I think!). Another fun quirk is --help=undocumented, to "Display only those options which are undocumented."
I know of some Canadian jurisdictions that used to require bicycle licenses. Toronto was one, until the 1950s.

I can't imagine a license scheme being repealed these days, as these things are all about the fees that can be collected, as well as the feature-creep that bureaucrats can promote. A drivers' license today goes well beyond driving, now, in its various official (and unofficial) uses.
historically the use of license plates were fought because of the potential to track the coming and going of american citizens. however, it was decided that it was not possible to do such tracking so they were allowed. the error is that provisions were not made that when such fears were realized the use of such plates should be revoked.
Would you be willing to bet $147M that someone hadn't figured out a way around that hardware security? I wouldn't..
You can also store it physically, like on a piece of paper I believe. Or on a USB.

Because on HN we prefer rational arguments based on evidence. We can debate the evidence, we can debate the logic, but let's start with a credible foundation.

Here are a few sources of evidence. Feel free to suggest your own. Inflation in the US is at depths not seen in 50 years [0]. Just this week, the monthly US inflation number was actually negative [1].

If you don't trust government numbers, try the billion prices project from MIT. It's an independent series with a different methodology, and it coincides (roughly) with BLS numbers [2].

I participated in this Hackathon.

It was a good hackathon.

I am happy for the winners.

The truth of the matter is, there were so many entries, that it was a complete lottery who ended up winning. I personally thought our app was great, and had a decent shot at winning, but I went to bed assuming 99% odds we wouldn't get picked. With that many entries the odds were not that great.

As lame as this sounds, I've learned the way to really win at Hackathons is to build something you wanted to build anyway. That way, if you win, it's a nice bonus, but you'll come out ahead no matter what.

The judging processes in these things is always suboptimal. I knew it was going to be a nightmare to try and narrow down that many entries to 5 in just a few hours. They were very optimistic in thinking they could pull that off. I think ChallengePost has a great opportunity to improve here by innovating so that if you enter a Hackathon, you get direct feedback from the judges (either quantitative numerical feedback or qualitative comments), so you get some acknowledgement for the hard work put in. The judging was indeed very light--as another data point I don't think we got a single hit on our app-- but I thought they tried to do something unprecedented and did a decent enough job and can learn going forward.

It was a very cool event, I'm happy for the winners, and hopefully some of these Hackathon software tools like ChallengePost and HackerLeague can continue to get better and help alleviate some of these transparency concerns for future Hackathons.

I would definitely recommend participating in future Salesforce Hackathons.
I guess that it's better to allow much more time for bigger prizes. Like the Netflix prize. That was a great mix of marketing and feeding the recommender system.

I disagree that mathematics is a universal language. Yes, "everyone" understands that 1 + 1 = 2 (most of the time, anyway), but that's not all there is to mathematics. There are vast numbers of different branches of mathematics, often compatible but also often incompatible (in both notation and semantics). There is a fairly common core of mathematical syntax, but beyond that different branches will use their own syntax. Perhaps that's like Lisps: the same fundamental meta-syntax but significantly different and often incompatible semantics and syntax on top of that.
