This has been really interesting to watch unfold. Starting with Andrew Warner's tweet (http://twitter.com/AndrewWarner/status/18538556171) "How can I get @photomatt & @pearsonified on Mixergy right now to talk? I bet I can bring peace here."

I've loved the Mixergy interviews in the past, but this shows just how good Andrew really is. He never pit them against one another, and really helped them each clarify their points in a last-minute interview that easily could have turned hostile.

Now that the code is on the GPL (the php at least), we can thank Andrew for brining peace!
We have implemented full-fledge access control including file ownership, read/write permissions on data/metadata, list/add/remove permissions on directories, etc. But we disabled it from the interface to keep user experience as simple as possible.

Later on we may enable them based on use cases and user feedback. Our API will include ACL management as well. Currently files are read/write accessible once shared.

Feel bad 'bout friends that didn't sign up.
Here's my situation,I launched a project like six months ago and I asked some of my friends and relatives to sign up and almost half of them didn't. Everytime we met like in a party, they're just saying "Hey how's your site? I haven't look into it yet but maybe next time." So I just whisper to myself "Do they really want to or they're just bullshitting me? I thought friends and family support each other." Does any of you guys experience this too and what are the things you do to deal with this kind of thoughts against friends and families?
And none of the links have a nofollow tag.
You asked this 3 days ago, so probably you'll never see my reply. But:

I read, and understood most of, Cosmos while I was in elementary school. For me, the educational process of school certainly was toxic. I can see that it works for plenty of other people, but for many -- some like me -- it is extremely adversarial.

It took me years after graduation to relearn learning, and re-discover focused curiosity, and to recall again how to intelligently consider the accepted notions that many other people have.

To be more specific, public schools lack (among other things) any focus at all on critical thinking and problem-solving. There are simply not classes for those at most schools. At best, a few teachers try to work them in to their class here and there, but it's not taught the way that, say, mathematics is.

Science classrooms are another specific example: they tend to concentrate on printed material and multimedia, and the few "experiments" that students do are little more than facades for re-confirming whatever thing is being taught that week. There is very little there to teach investigation, or to drive intellectual curiosity.

I say this as someone that was fortunate enough to attend some of the best schools in the Bay Area at the time; I imagine that my experiences, mediocre and toxic as they were, were still quite a bit better than what the vast majority of students are exposed to.

This is not to say that I didn't have some brilliant and dedicated teachers, however. I remember several of them quite fondly, all the time.

You absolutely have a choice. And I've walked that path, so it's not just a meaningless platitude. There are assholes in the world (along with people who just don't care), they do fucked up things and they're not going to change. In the end, the best that you can do is distance yourself from them, both physically and mentally, and get on with your life.

ps. I doubt that YouTube have much of a choice either. It's either shut you down or get sued by the content owners. I suspect that after all the work you've put in, you've lost a bit of perspective on that.
I'm guessing it's:

a) RFID is readable from further away than they'd like you to think.

b) You don't know when your RFID card is being read.

c) Points a and b make tracking you really easy... for anyone to do.

d) The only thing that should (ideally) be stored on any RFID chip is a unique number... not any history (recent transactions), personal data (name/phone/picture), or payment system (think public transport) where the actual info about how much money is on the card is stored on the card itself... but that's exactly the type of information which is stored on these cards.

e) Nearly all encryption mechanisms are shoddy, either because they're poorly implemented open standards, or developed in-house by the vendor (security through obscurity). Cards that make use of real encryption would be (are?) expensive to make.

Here in the Netherlands the entire public transit system is being switched to an RFID-based system, and even to a non-security expert (me) it's clear that the system is based on an insecure premise (d), and would be very vulnerable to unknown scanning by someone wishing to track you from a decent distance (a-b-c).

I was interested in the security of this system, and found this video (http://events.ccc.de/congress/2007/Fahrplan/events/2378.en.h...) of some hackers who did an amazing job tearing it to shreds. They're pretty adiment that nobody is doing adequate encryption on RFID cards. If you're interested in this at all it's an amazing hack, involving dissolving the cards layer by layer to see the code.
You can block their updates if you like (by editing your HOSTS file I imagine), but then you'd be running out-of-date software.

I don't think that you can blame Chrome's updates for breaking that extension. It's much more likely that the extension is broken.
It couldn't have turned hostile, because one of the two was level headed and non-combative. The other guy was just talking gibberish.

>There are real journalists out there. There are people that do really thankless work bringing important stories to light.

This is exactly what she's talking about in #9.

99.9% of all journalism is not "bringing important stories to light" its getting fact checked information to the masses. The people covering the local town flower show, those are real journalists. So are the ones covering post disaster damage, which sounds more glamorous than flower shows, but it's still not bringing things to light, it's conveying important correct information to people who can't go get it themselves.

The idea that REAL JOURNALISM is nothing but breaking scandals and exposing deep secrets is harmful to the gathering of normal work-a-day journalism because people stop talking to you.

And it breeds bullshit sensationalism because if you think it's not worth writing up if it doesn't piss some one off you start ignoring actual news and start printing half false accusations just because it sounds like "real journalism." It's exactly the attitude that leads to the current situation of fatuous screaming heads.

Well Adam has stated in at least one interview that he reads Hacker News regularly so maybe we'll have a nice anonymous reply :)
While I agree that not paying employees (consultants, etc. ) with money extends the runway while running on the founders captial I have a couple problems with this tactic.

1. Like relying on an unpaid interns you limit your potential employee pool to the group of people who can either afford to work for free (no cash right now), have no better option than to work for free, or who have to work a second job to pay their bills.

2. Most of those people won't understand the probabilities of success and payout amounts to founders, employees, and investors under the variety of plausible financing and exit scenarios.

3. You didn't mention personal guarantees on the company's debts to the employees. How do you collateralize your obligations to the people? Are the employees retained under this plan sophisticated enough to understand the credit risk they're taking? Are there covenants or debt coverage ratios you're committed to maintain?

4. What happens when you fire someone (or they quit) before the fundraising?

Why not just make a loan to the company yourself and give them cash? 2nd mortgage or from friends and family... Seems cleaner.
Yes and no. Yes, that is a valid #define; but the following program must work:

#include <stdio.h>
#undef getc
int main(void) {
getc(stdin);
return 0;
}

so it cannot be implemented as only a macro.
Finally. It seemed to me completely obvious that CSS, images, etc. couldn't be forced into GPL. The PHP still seems a bit of a gray area, but at least now there's a semblance of consensus.
I was agreeing with you, and providing a simple testcase to show that you were, indeed, right (because I agreed that the behaviour is somewhat surprising). Sorry if that wasn't clear.
Good luck with it. There seem to be decent statistics on the benefits of various physical therapies and the recovery of patients. I suppose it would be a good pitch to narrow your target down to the most successful areas and methods of treatment (deep tissue massage on the lower back, or what have you) and get an industrial designer to make some sexy sketches of devices.
People I know in consulting don't get paid for their ideas. They get paid for their results and their experience in tackling certain types of problems.

Fundamentally, the ideas don't stand on their own. Their backed by a name institution that delivers results on the ideas.

a) it's a radio signal. However low power it is, it gets transmitted huge distances while still being detectable (especially if you capture it multiple times to read through noise). I'd love to take a massive dish (say, 20 foot diameter) & see how many can be captured from inside a neighboring building.

b) I have yet to hear of a single RFID card which has a switch on it to address this. It's a big security problem. I saw one hobbyist hook up an OLED pixel, but that's it.

e) I've heard of a couple, very expensive, challenge-response and public-key RFID systems. That is acceptable for authentication, but I've never heard of them actually being used, and one or two were only proofs-of-concept, IIRC. Many (I'd say easily most in use, from what I gather) simply transmit a unique ID, that never changes, which is used to perform X, which is ridiculously insecure.
This was discussed on No Agenda recently as an example of why corporate advertising is bad for media that does this kind of work (although Mythbusters rarely broaches subjects that run against corporate culture).

It seems odd Adam would have made up his original account, but only he knows the real story at this point.
This is a weak argument. Deferred key constraints and the other intra-transactional feature mentioned are hardly bad practice, since you're relying upon the database to cover your ass. Go figure, that's what a database is supposed to do. You should be free to do anything in a transaction you wish, it is, after all, not committed until you say so.

The appeal to authority doesn't add any weight to the argument.
Treehouse is focused strictly on photos taken with mobile phones.
Having worked at a think tank, think tanks don't get paid for their ideas. At least not in the way we're discussing them. They get paid for doing research and folding this reseach into policy.

Let me put it another way. The recommendations that a think tank comes up with isn't worth the paper it's printed on without the weeks/months of backup research that shows how the recommendations came about. That's what is being paid for, not the idea/recommendation.

Are you talking about active or passive RFID? I was under the impression that most RFID in use is passive. In that case, you'd have to transmit something to get a response, unless you're talking about camping out in an area where lots of cards are going be activated by various things other than yourself (e.g. entrance to the transit system). But even then the transmitting power of the RFID chip is proportional (?) to the power used to activate it, so something that only expects to read it from 2 feet away isn't going to blast it with enough power to be reliably read from 100 feet away, unless I'm misunderstanding how people do those long distance RFID reading records...
i think you're right.

with endless choice in terms of news, analysis, opinion, etc., it's difficult to get people's attention. but i think the general definition of creativity -- the production of something original and useful -- is the answer to my dilemma.

in other words, i think YC's motto of "make something people want" definitely applies here. the answer is probably that people don't want just another blog to read.

just another blog doesn't fix or solve anything for people.

but i do think the problem of getting initial users who love what you've created is a problem for all creators. and i was hoping a useful discussion about that would be the focus of this thread.

anyway, i'll keep tinkering. thanks for the input.

I'm not sure you understand the use of NULL.

NULL is not "default value" or "I don't care", NULL signifies "this might have a value, I just don't know what it is".

There is a very significant difference between a payroll record which states your pay is "0" vs. NULL. If the database is putting in default values, you have no way of knowing whether the employee really did have a salary, but it was incorrectly inserted as NULL, or whether the employee is unpaid.

"The traveling salesman problem asks for the shortest route connecting a set of cities, given the distances between each pair of cities. The rub is that the number of possible routes grows exponentially with the number of cities."

Is it just me or does the traveling salesman problem have (cities-1)! solutions? thus it is not exponential? and is in fact far more annoying?

You came with an elaborate points, but you seem to forget the main problem that the author seemed to scratch surface of:

Smart people, just like other people, have ego. And when they get driven by it, they suck.

Now please reread your points.
He did make a cast, so it's a lot easier from this point (except for the electronics I guess).

The guy even mentioned this was an on/off project for 17 months, and it also looked like a lot of trial and error in the beginning to get the shape right. A dedicated modeller with a stereolith machine could slam that out a lot quicker.
I helped recruit for a 20-person startup at my alma mater in the fall, and found:

- if your brand isn't immediately recognizable as a tech startup, signs like "Seeking CS / Math majors" are tacky but help immensely with capturing the interest of students who are browsing and want to know they won't be sucked into talking to a company totally outside their interests

- we spent much more time pitching our startup and answering questions about "what we do" than I imagine the average recruiter at a larger company has to do

- because the conversation almost always starts with them asking about us, if you're interested, you have to remember to turn the conversation on them to find out more, instead of just being left with a resume

- (more general) knowing which classes are good / hard / produce interesting projects helps a lot in evaluating what a particular candidate has done, and whether it matches with your company's needs.
Good for you. Alas, we have abandoned mobile phones for the sake of frugality.

But that's what we're talking about here, I believe. As with anything, there are both good and bad ideas. Think tanks are paid to come up with good ideas; since ideas are a market for lemons (asymmetric information about their worth), the thinktank then signals that the ideas are good by providing accompanying research. The thinktank could just tell you their ideas and keep the research to themselves, but you probably wouldn't believe them.

Now, since 90% of the output of all cretative processes is crap, and that includes ideas; and since ideas experience network effects where the best ideas will gain supporters who will exponentially increase the "execution" multiplier for the idea, while the long tail of ideas will never get executed on at all; it becomes pretty obvious that the median idea won't have any market value whatsoever. Talking about "ideas" as if they all had the same worth will then lead you to believe that, since the median idea isn't worth much, no idea can be.

What I'd want to say here is "the largest number nameable using 1000 symbols in second-order logic" (not original, I think someone else won a contest that way). But the fact that someone can ask "Which formulation of second-order logic?" probably defeats this unless you can also, in those fifteen seconds, cite a standard formulation of second-order logic and a standard axiomatization of number in that formulation, otherwise it's an ambiguous specification. HOL is a standard and formal formulation of higher-order logic that I can think of in fifteen seconds, but I wouldn't be able to think of a standard formulation of Peano Arithmetic that was already in HOL.

Actually, now that I think of it, "the largest number nameable using 1000 symbols in HOL plus a successor symbol" might work, since you can define addition, multiplication, etc. in higher-order logic using only a successor symbol.

Interesting fact: This is a fundamental jump up from first-order logic, which is a fundamental jump up from Busy Beaver, and then once you're there, it's operating at the highest level of abstraction that I know about or have ever heard of. There are things you can do to make that number bigger - picking a different ordinal for the order of logic, recursing over how you get the number of symbols - but they all amount to saying "plus one", and not jumping to a qualitatively different level of abstraction. Once you abstract over second-order logic you are, so far as I know, done.
