Again, the "random number" comes from a distribution. You can have a random number from the binomial, normal, etc distribution, and the output will look quite different. Also, there are clearly bounds on the distribution. Etc. They absolutely do need to understand how their pseudorandom number generator works in order to understand the properties of their simulation.
> Are you really sure Lehman's bonds went to zero?

The official story is that market essentially froze, that no one would buy. I'd have bought everything I could get my hands on at fractions of a cent (and possibly more), but they didn't ask me. (After they let individuals back in, I thought that all of the bargains were gone, so I didn't go bottom fishing. Big mistake. The great deals were gone, but there were still some opportunities left even when I got around to looking.)

The money that left with the derivatives may have kept the bonds at 70-80 cents. Unless Reserve Primary was 100% Lehman, that might have been enough.

> As for the derivatives, when it came time to settle them, as widely predicted they mostly canceled out with only (from memory) 6 billion US$ changing hands.

Yup, but no one knew that when the derivatives were being made whole while everyone else waited to see what was left.

> You can set the pointer to any address, which includes future stack.

This is wrong. Attempting to use random pointers to outside of what your compiler and malloc allocated is undefined.

And indeed, aliasing issues like in your example will prevent gcc from optimizing out excess strlen; it can only do so if it can prove that both global memory and the buffer passed to strlen have not been modified. Local variables and return values cannot alias anything, and part of the guarantee of pure functions like strlen is that they have no side effects.
"result" is not necessarily on the stack, and stack growth direction is implementation-specific: http://stackoverflow.com/questions/664744/what-is-the-direct...

"Does anyone give a shit about your dumb idea?" should be a bumper sticker

I dislike this style of communicating a point. There has been an epidemic of it on the web over the last year or two (that and its close cousin, the "X Reasons Why Your Y Sucks" post). Apart from being crude and overused, I think it sends the wrong microsignals. Many good ideas seem dumb at first. To me it indicates a deep misunderstanding of the creative process to blast anything in the delicate, incipient stage with this kind of harsh language. The most consistently creative people I know don't do it.

This may be a merely stylistic point, a matter of taste, but I suspect it's more. The way one puts things has effects. In particular, it affects what ideas and possibilities open up next.
> I don't know why it's such a bad thing to give welfare assistance to young single mothers.

We really want to discourage single motherhood because it's pretty crappy for the kids.

Yes, there are other crappy things for kids, but that's not an argument for creating more.
"Some of the styles are not to my taste, but three or four of them are clean and simple and easy to read. They provide someone with no CSS a head-start. "

Yes and no. It's probably better than nothing, but nowhere near as good as using something that considers layout as well, such as 960gs, jQuery-ui, Typogridphy, YUI, Blueprint, and so on.

The CSS, much like the markup used in the sample doc, is more "Here's my thesis" than "Here's my Web site/app". And that's clearly related to the age of content.

It is art yes, but it's not great art simply because it is done on a computer. I am not trying to say that it is not good, simply that since it does not exist in the physical world on a solid object it is not 'great'. When I see the end result, I just see a picture. There is nothing. There is no evidence of emotion in the brush stroke or feeling in the texture. His picture is just a bunch of pixels. It looks good but that is it.
There are unhappy people in every industry and in every position. But the game industry has surpassed the tipping point for popularity and 'glam' to make the detractors have enough social incentive/attention to be very vocal.

There are legitimate gripes, complaints and out right abuses in the game industry. But much of the brokenness in process or hours or management or etc also exists everywhere else. It is the unfortunate nature of a work environment. You do not read/hear about everywhere else as much fewer people are passionately following their output or dreaming of breaking in.
Advice for my first startup?
Looking for a little wisdom from the ycom crowd. I'm just getting started on a little idea that's going to be my first foray into the web startup world.

I'd love to hear any/all advice you have for me as I get started.

Backstory: I've been in the web world as an executive-type for several years, but never started my own company. I'm not a developer or designer, I just have an idea and a really clear roadmap for what I want to see happen.

Would love to hear your thoughts.
If you decide to do this, please consider using a larger font size on the iPhone, too. For my browsing habits, that would be greatly appreciated, though perhaps others find the font size on the iPhone to be OK.
That's a view I can certainly buy, that intervention must be careful and is error-prone--- perhaps even so error-prone that it's rarely worth doing. In libertarian circles at least, though, I often encounter a much stronger claim. I don't hear people say things like: maybe it'd be great if we could intervene in an ideal world, but alas such interventions are error-prone so we'd better not. Instead, a much stronger claim that no intervention is necessary because the unfettered free market is already at least reasonably close to ideal. This is particularly strong in Rand-influenced areas of the libertarian universe. The explanations are usually some extremely simple version of classical economics, invisible-hand, etc., leading to assertions that the free market efficiently allocates resources, rewards merit, etc.

That's the part that reminds me most of the ecologists: a belief that we're fortunate enough to live in a universe perfectly constructed such that these complex dynamical systems (economies, ecologies), if only we'd stop mucking with them, would live on in magical harmony, aligning with normative notions like "merit" and "balance" and whatnot. I tend to view them both, instead, as difficult to analyze, hugely complex systems filled with all sorts of weird attractors and unstable states, which won't necessarily result in particularly great outcomes whether left alone or not.

In short, I agree that most of the people who claim to know what will happen if you intervene in a market are naive (i.e. unintended consequences are likely), but I also think most of the people who claim to know what will happen in a free market (e.g. that it will reward merit) are also naive. And most libertarians I've met fall into the latter category.
What would be the right tool, then?
And much appreciated. I don't know when I'd have had the stones to switch to VPS (I still don't think of myself as a sysadmin all that much) if you hadn't helped us jump over to Slicehost. I've got a 2GB RAM node over at prgmr.com, now; more RAM than I know what to do with.

Site grows slowly because it's growing steadily. Well, that, and I haven't had the time to set up income or the really nice features that would depend on it. :)

What made people masters in the past was the triumph over fear. Much like typing on a computer when you think of the words that you are typing you type slower than if you just let your hands work the keyboard. The great artists of history overcame their fear and let their body and mind create. When you bypass the fear there is not the same struggle to master the medium. If there is no longer a barrier, you will get good media but everyone will be able to do it and it will no longer be great.

The filter can't be about anything other than shoring up political support. Hopefully the incumbents pick up a few seats in the election and they'll be able to drop the legislation.

We love to call politicians stupid, but they're not that dumb. It's been pointed out ad-nauseum that the filter wont achieve the stated purpose (eradication of online child porn). The rationale has moved to making sure kiddies don't 'stumble' upon the internet nasties.

More sensible legislation would be to mandate that ISPs offer filtered & unfiltered connections. Individual households could then make their own choices.
I'm not sure; I enjoy playing with these pages, resizing my browser window down until it's perfect for me, rather than having the width predefined. But I might be strange that way (and most users won't even know how to resize their windows...)

I dig the upgrades you made this morning. thanks again for making that web app!
I think it depends on a few factors, namely:

- The likelihood of the company selling (consider both near or long term) or going public

- The difference between 10% profit and the salary you would make with 10% ownership

- How likely profit is to increase compared to the likelihood of the company selling

In other words, it totally depends on the company and the situation. A web design company will probably never get acquired or go public, and so ownership doesn't mean much, whereas if you're working on something that interests Google or Facebook, the chances of acquisition (and the value of ownership) increase exponentially. Then again, my reasoning is based purely on monetary gain - you should probably consider the impact of ownership on the company and your personal life/career as well.
Let me see your papers, let me see your source
I suggest you pick a direction and keep pushing. There's a particular set of projects I sometimes look at, and I find them overwhelming. I think, "This guy is way ahead of me", or "This guy is way smarter than I am". But here's the thing—they are projects I did myself:

* This guy is way ahead of me: http://railstutorial.org/book

* This guy is way smarter than I am: http://thesis.library.caltech.edu/1940/

I only feel overwhelmed because, in a single moment, I'm looking at the cumulative effect of months or years of effort.

Pick a direction, and just keep pushing.

I will buy this but I highly doubt that the Indian Govt. can really make it available in markets at current prices.

There have been many such products shown to journalists amidst hype in the past and we are yet to see those products.

I am glad it is being done by the Indian Govt. but I feel sad for the private software enterprises who are just sitting on piles of money without putting any of it in producing something truly innovative. One company that comes to mind who can and rather should make something like this is HCL.
Stephen Conroy seems to repeatedly fail at understanding the basic concepts involved in information security and the Internet. A recent quote from him at the launch of the "Cyber Security Awareness" week [1]:

"There’s a staggering number of Australians being in
having their computers infected at the moment, up to
20,000, uh, can regularly be getting infected by these
spams, or scams, that come through, the portal"

Watching the video on the Gizmodo site is like watching a slow motion car crash.

Another car crash video is of Senator Conroy trying to explain how the "Russian mob ... hacked" a dentist's website [2] as an explanation for it ending up on the leaked "Internet Blacklist" from the filtering trial [3].

I don't underestimate the complexity of concepts in the information technology space, especially for those outside the industry. And I particularly don't envy the people whose job it is to explain to the general public the issues and come out with (and sell) realistic public policies.

However, you'd hope the man who has ultimate responsibility for these policies would have a basic grasp and be able to communicate it more effectively. More importantly he sorely needs advisers that both understand the issues and are able to properly brief him.

It's a tough question. But in my mind it is more related to the Australian political culture than it appears. And I note a lot of parallels between the formation of modern states and the advent of internet legislation. I'll try to explain my view - sorry if it is an essay :P.

Essentially, the nature of a modern state is the governing body has monopoly of force over a geographical area. By extension, this allows certain advantages, namely extraction (which from a one dimensional or conventional perspective can be viewed as taxation or army conscription) or coercion which again, from a one dimensional perspective means the ability to force a society to act in a certain way. For instance, one could view the inquisition to be coercing (by means of force) the population to a particular religious doctrine. Or from a modern perspective

Now, the space of the internet in it's current form can be interpreted as anarchic - a power vacuum of sorts. The nature of a politician is to expand into all power vacuums in a given area - it's what they do. The vehicle is legislation. As the internet grows and becomes more a part of our society than ever, the need to control this vacuum is more important than ever. China has been especially proactive in this regard, but more states are following suit (consider the US is also looking into a RealID programs).

But the thing that is so bad for us Australians is that our political culture is very ambitious. For decades our society has been screaming out to appear as a major player on the world stage. The politicians, understandably are more fundamental on this issue - as all people in a position of power will be.

This has changed our political policy to a form of 'any means necessary' legislative agenda to modernise and to expand Australia's power and thus influence AND importantly to appear to the world as an example of modern proactive state making. This is paramount - our leaders perception of ourselves on a world stage. They crave world recognition.

A more obvious example will be the former prime minister Kevin Rudd's ambition to increase Australia's population to 60 million - an almost threefold increase on a land whose space and water is already on the brink. A detriment to society is ignored in favor of this increase in power.

The current internet legislation is essentially a conglomeration of these factors. And due to a series of conservative rule (and by extension the right-leaning attitude of the two popular governing parties), this new approach to modern state making has often come in the form of very conservative legislation.

Again, I am sorry for this essay. However, I prefer to view this problem from a structural standpoint, instead of any ideological agenda. Though I think this still may be a factor, IMO the system is more to blame.

No. "Doesn't support backtracking" suggests that it doesn't support features that re backtracks for. In fact it does.

Also it is technically possible for re2 to (although it doesn't currently do this) add backtracking to its current strategy. If it did this, then it could offer all features of re, but would frequently be much faster. However I would not permanently rule that possibility out.
I always assumed that was laziness on the part of the designers, and decided to make my layouts as fluid as possible as a result. But, since I'm more of a code guy than a CSS guy, I'd end up spending hours perfecting the layout, instead of developing, and I'd end up setting max-width and min-width anyway (to wide ranges, something like 600 to 1500px, but I'd use em). I also always used em for units, in case the user was using large fonts. I always hated a site with lots of text that fixed its width to something small like 550px, until I found out about the Readability bookmarklet.

So, 1: is there a good reason not to use fluid layouts? 2: What should a code guy like me do to minimize time spent designing prototype fluid layouts, before I'm ready to pay for design?
This is a classic Dunning-Kruger situation. Penrose is out of domain of expertise here. He has not bothered to study the theory of mind (eg see the lack of relevant references in his book).

His arguments do not stack up, as extensively documented elsewhere.

This is not the first time that a famous physicist/mathematician has got it drastically. Neils Bohr was an animist - he believed along with many people at the time that there was some magic hidden essence to life that went beyond material things. When told about the discovery of DNA he said "Yes, but where is the life?".

That's one way to make NYC even less affordable and friendly to tourists on a budget.

I've met some very interesting and friendly people in 'short-term apartments'. Mostly foreign students/travelers on vacation, people moving to NYC for work and using it as temporary housing until they find a real place, or just regular Americans visiting another city on a budget.

They make it seem like these places are unclean or unsafe, but they're not any more dirty or dangerous than any other apartment.
Amen to that. I did the LA commute (~3hrs/day) myself for several years before quitting. Never again. Now I live in Seattle and ride a scooter to work -- 10 minutes from door to door.
Wait, does this mean this stops businesses like Airbnb from operating in NYC? Regardless, the whole thing is b.s.
Wow. This is a direct swipe at airbnb.com no doubt (a YC startup). New York must be the largest market for short-term rentals.

I can't answer the philosophical/ethical question, but on the legal side, if this is considered a kind of "zoning" (prohibiting commercial use of residentially-zoned property), it's long established that that's a permitted kind of regulation: http://en.wikipedia.org/wiki/Euclid_v._Ambler
That's not a very good example. The Cabinet consists of the heads of various Departments, whichever ones the President wants to hear from at any given moment. The Departments are created by Congress.

An Amendment wasn't required to create the Air Force any more than it was required to create the DHS, or is required to create any other Federal agency. Congress has the power to create, destroy, and reorganize Federal agencies as it wants to. So in 1947, Congress created the Department of Defense as a Federal Department, which the Constitution allows them to do, and put the Army, Navy, and Air Force (new) under it. There wasn't anything even vaguely unconstitutional about it, even taking a really uncharitable reading.

Congress creates new Departments fairly regularly; there wasn't a need to go through the amendment process for the DoD any more than there was to create the Departments of State, Transportation, Energy, Labor, Education... etc. All it takes to create one is the same process to pass any other piece of legislation.

I would personally not be against requiring an amendment to create new agencies, just on the grounds of controlling governmental scope creep, but that's not the way things are set up. Congress has been creating Departments since the ink was barely dry on the Constitution itself.
I heard a lot of moaning about this at OSCON.

I'm going to be blunt. I actively dislike Perl, not Perl developers, but Perl. This is because I believe it not only gives people the rope to hang themselves with but encourages them to do it in 6 different ways.

The problem that I have most though, is the reaction to this silly bit of fun. Instead of proving that Perl is awesome and showing what you can do with it, I mostly heard a lot of griping. I'd really love to see Perl 6 succeed and those guys do something amazing, new and innovative that breaks from the mold that I think of them in. But until they do, I'm not going to listen to their whining.

P.S. Tim is also right there are lot of great things we got from Perl, but that doesn't mean they should be allowed to coast on them forever.
I would say the observation is accurate. I think the owners / employers see it as a supply and demand problem. There are a lot of enthusiastic, gung-ho novice programmers would give an arm and a leg to be in the gaming industry.

Many enjoyed playing games, so naturally they decided to into the this field. These individuals will compensate their lack of experience and theoretical understanding of many CS subjects with sheer enthusiasm, they will work 12 hour days, weekends, for relatively low pay, putting up with lots of crap, until ... they burn out. When they burn out, there is another battalion of enthusiastic kids waiting at the door and, then the cycle continues.

It is not that this doesn't happen with other programming jobs, but there are just not that many people who are as excited about database scalability or say, machine learning as there are individuals excited about games. Exploiting someone like that and having them burn out, would mean having to look long and hard to replace them. Therefore pay is better, hours are better and the environment is healthier.
