I think you hit the nail on the head with this statement "often due to those particular cultures becoming deeply interconnected and unprepared for large scale changes." In other words, the social complexity makes a culture vulnerable, and climate/agriculture pressures can essentially cause failure where none was possible before. That's close to Prof. Tainter's thesis, actually, and he points out that there are very few cases of large-scale cultures addressing these problems by simplifying but when they do they can survive.

The example he gives in his lectures is the so-called Byzantine Dark Ages which were a deliberate transformation of the Byzantine Empire in response to the Arab invasions (going from a professional army to peasant militias, etc).

But most cultures that I know of aren't even proximally wiped out by climate change. The Persians were conquered by the Romans on the battlefield, as were the Gauls. The Western Roman Empire appears to have collapsed primarily from inward pressures, not outward ones, and the agricultural failures there were the result of factors other than climate change or even man-made environmental damages.

Some cultures do fail due primarily to environmental reasons (Greenland and republican Iceland being the best examples), but I don't think they represent the general rule. Iceland never was a particularly fertile place to grow things (vast amounts of environmental damage were the result of grazing animals simply because there's not much else you can do in Iceland), and neither was Greenland even before the Little Ice Age....
R.I.P. Good Times 2.0
Facebook IPO disaster, coupled with Yelp and Groupon and the others, is the real death knell. PG's letter merely states the obvious.

The goal of the VC game is to get 10x+ returns. That only happens for early or mid-stage investors if there are investors down the line investing at higher valuations. Those late stage investors depend on the IPO exit. If the late-stage investors lose confidence (which is what appears to have happened), the mid-stage investors lose confidence and thus the entire market contracts.

From the other side, the entire wall street game is crashing. People, for better or for worse, are convinced that the entire equities game is a sham. Volumes (which lead to commissions and revenue for the firms) are down in all of the asset classes, and the bonds have reached near-ponzi yields (swiss bonds actually have negative yield, which means investors are actually paying interest ...), so the "retail investor" who traditionally buy into the IPOs aren't playing a significant role anymore
It's very smart for these celebrities to build a brand other than what they're currently doing. Not many singers can be hip for more a few years, and not many models can look better when they go past 40. It's good for these people to build a second career later on so if/when they need to switch, the options are open.

Props to Ashton Kutcher to leading the way for venture investing. Smart move.
I'm amazed Cloudflare got a response from Google that quickly. I'm a paying Apps customer and I don't see responses for 24 to 48 hours on security incidents, not to mention that Google doesn't have a stellar reputation when it comes to things like "support".

Goes to show, it's always who you know (or it's bullshit, which is less likely). Or I don't have enough users.

"... But no one knows yet how much. Possibly only a little. Possibly a lot, if it becomes a vicious circle. ..."

The email is counter-intuitive because being truthful and signalling a possible crunch speeds up the observation. It also gets you trampled as the herd looks at the lead changing directions ~ http://news.ycombinator.com/item?id=4067278 but it also forces teams to 'adapt' quickly.
Correct.

But it was the main reason you or I even discuss him right now, which implies that it was one hell of a multiplier.

My problem is that the ratios are very distorted: 1% work vs. 99% luck. Work is necessary but not sufficient is all I'm saying.

Hence how would one optimise the multiplier (whilst obviously working on being just plain good), if that is at all possible.
If off-the-shelf AI has the intelligence of even a ten year old, imagine the amount of automated snooping that can go on.

Why worry about sifting for keywords in text messages when you can literally read all the text messages and infer meaning from them, even when it's deliberately obfuscated?

It could lead to a Brazil-like future where you're drawn in to a mess of trouble because you used too many euphemisms when texting your significant other. "I'm bringing home the package right now..."

What do we do to push back against this kind of thing? Drop off the grid as Stallman would have you try? Eject yourself from society as a whole? Or will it be practical at that point to have sufficiently private, well encrypted channels of communication that you won't have to worry too much about that sort of thing? Technology does cut both ways.

It doesn't require an emergent intelligence to cause a massive shift in the way we view technology. A number of low-level intelligences that can be easily replicated may be the first disruption.
It's more difficult to profit from scientific exploration than it is from weapons and the maintenance contracts that come with them. The military industrial complex has a stranglehold due to simple market forces.

This appears to me as a collection of jQuery plugins that is masquerading as a better version of jQuery. I really don't like the name, and I hope whoever controls the jQuery trademark puts the kibosh on this name. These plugins should stand on their own merit, and should be advertised as something other than jQuery++.

Frankly, I have also not really liked that jQueryMobile, and jQueryUI used the jQuery name because it killed the prospects of better alternative projects, but at least they had endorsement.
My biggest grievance with FPS games is the stick controls not the angle of the camera like the mouse does, but the rate of change of the angle of the camera, one degree removed from actually moving it.

There are a few trackball controllers (http://trackballcontroller.com/) which promise to fix this, but I wonder about that. Most balls are removable for cleaning, and anything removable on a controller will end up underneath the couch eventually.
I still think using any kind of DRM is an unethical overkill for controlling the MMO..G and the like. Firstly, the game can be designed better avoid (some) exploits. Secondly automated mechanisms can be built on the server side to prevent cheating (monitoring unnatural stats boosting, unrealistic mods and so on). I agree, that it's not easy to do it manually. So, write server side protection code for that. It's not DRM, and not some kind of client targeted kill switch. If the user is caught - ban will follow. Let them register again, and get another ban if they want to waste their time. And if that cheating is so hidden that it's not even unnatural IG - who cares (i.e. it's still not fair, but at least such user doesn't have big impact).

From the player perspective, I'd choose a multiplayer game based on the community. Sometimes community can identify cheating just by observing something unnatural, and those users will quickly be boycotted. So GMs are needed to intervene when human decision is necessary. They not necessarily have to detect the issue themselves first.
Can you give an example? I don't generally have these problems and would like to see if it's my way of thinking or if you're working with vastly different data to me.
I'm not sure of the details here, but it wouldn't be too hard to make sure the reset call arrived in the middle of another call.

Yes, it most certainly is. But what C++ will ask of you is probably more than all but he most disciplined engineer has to spend on an implementation.

It takes knowledge and maybe even wisdom across a development team to build a sane, stable C++ application or system of any size.

If you think you have a team of A players then go for it, even they will bicker and fuss over the implementation trivia that consume their cycles as they try and build a solution.

But for some things, C++ is probably the best choice. Just know what those things are before you take the plunge.

C++ is not a general purpose OOP language to be considered equally with even a language like Java. If you dont have the discipline to rock C++ dont even try it, it will kill you.

Improbable, Enjoyable, Increasingly Profitable Life of Michael Kobold
Hack to the Future (June 8-10, SF)
I read this with a heavy heart, especially after working at Facebook before my current startup.

Facebook is an amazing company with some of the best people in Silicon Valley working to make Facebook a once-in-a-generation company.

But if Google debuted at $25b, and grew into a $200b company, how can Facebook grow by a similar multiple starting at a $100b valuation?

In my opinion, opening at $38/share sucked all the oxygen out of the room, in the IPO market, especially the later stage market, and potentially downstream as well.

Instead of debuting at $50b or even $75b, the delta was the price of the collective hope of entrepreneurs and early stage startups everywhere.

Because at the end of the day many investors will ask, "If even Facebook couldn't do it, who can?"

The price of leaving a little money on the table for most retail investors would have been worth the good will and Facebook's reputation. Because Facebook really is a great company that is doing and will continue to do great things, but PG is saying the air is gone, and no one knows if more will come.

Is all this a bad thing? Perhaps more companies should be valued based on revenue in stead of API calls/month etc.

I attended a talk by Instagram post-buyout. That's where I got the impression that sharding was not a huge obstacle for them (though it was significant). Keep in mind their entire data management team was 2 people I think.

My point was that sharding is not an absolute "have it or not". Some features require major engineering efforts to get anywhere at all, but sharding is not one of them.

But if you think the overall effort is less with MongoDB then go for it.
Minor nitpick, but the element used to add icons should be a <span>, or even better, a pseudo-element added via CSS.
I don't deny this at all. There might be a lot of people who are as hardworking and ready with something to give them a multiplier. But they might have somebody like Mary Gates as their mother.

My problem is people taking that as a reason to not do the base work at the first place.

I know of people who hunt 'luck' stories whole day to prove why they being lazy is OK. And not just that, now they expect to get equally 'lucky'. And when they don't they call it 'injustice', 'unfair' and things like that.

So FB clusterfuck of an IPO might end up being really good for them because now it will be much easier to hire...
And just like that, from being disrespected and the world wanting them to lose, they will now be immensely popular with the world cheering for them!

On a serious note, I think if Oracle wins this, maybe there can be a system that can be setup that is cost effective to invalidate most patents.

To those having fun saying "pop", contribute value not onomatopoeia.

The clearest message in PG's letter is simply "The startups that really get hosed are going to be the ones that have easy money ... So don't be that startup."

If you have a viable business then you can either a) proceed without venture capital or b) prove yourselves enough that you'll get the terms you need. Yes, (a) may make you move slower, and (b) means that potentially brilliant ideas that have a bright side just past the edge of horizon are more difficult to get off the ground, but this has always been the case.

One of my mentors always quotes "you don't know the value of your captain until you hit turbulent waters". These are our turbulent waters. For those of you ready for it, this is a time of opportunity.
Ask HN: What skills do I need before tackling The Algorithm Design Manual?
I’ve been reading a book called “How To Win At College” by Cal Newport of Study Hacks fame. The book is broken up into a series of tips and tricks that are meant to ultimately lead one to greater success as a university student. One of the tips in the book is “Do something better than anyone you know.” I’ve decided that I want this skill to be the ability to solve algorithmic problems by applying algorithm theory to real-world problems and I’ve decided on The Algorithm Design Manual by Skiena as my introduction to algorithms.

We all agree that computer science is not programming, but I believe a firm grasp on basic CS concepts can make anyone a better developer. This relationship is similar to that of a journalist who studies English. While a journalist can have a great career without studying English, there is certainly an argument that theory (English) is just as important as application (Journalism). For programmers, this is the difference between studying theoretical computer science (algorithms, data structures, AI, etc) and learning programming languages (Python, C, etc).

My goal is to become proficient at engineering optimized algorithms for solving real-world problems. This won’t happen by diving right into a book on algorithms and that is something that I fully understand. My question is this: What do I need to know before I start tackling The Algorithm Design Manual? To be a good algorithm designer one certainly needs to know how to analyze the time complexity of an algorithm. What math skills, specifically, are required to do this well? I’ve heard that going through a book on discrete mathematics would be a good idea. What else would you recommend? Statistics and probability, perhaps?

Ignore reality if you want to. It's just never going to happen. Java had its chance. Java had every possible chance. Java had the advantage of making a deal with Netscape to purposefully cripple javascript to help promote Java. Sun tried for a decade, trying and trying to make Java the defacto web application language. Sun tried and tried to put its java VM in the browsers. And it lost. Java lost. Javascript won. End game. Being in denial about it won't change it. Trying it again isn't going to change the undeniable reasons that Java did in fact lose. Insisting that a VM is the best way to make web apps won't change the reality that we explored for years and years that it just simply isn't. It didn't work. It can't work.

Get over it already.
Out of curiosity where did you get them printed in metal? I've got a few pieces I'd like to get made out of metal that could be CNC milled but would cost me significantly more than I'm willing to pay for them at the moment (last place quoted me at around $200).
Instapaper is a place, time AND device shifting service for content. Its market leader position on one or two devices was made more precarious by not branching out as soon as possible to as many devices as possible.

Marco's personal inclination was to support only platforms that he himself used—that's why he built a free service into Instapaper for the Kindle platform while ignoring the Android platform. I initially had an iPhone and an iPad, on which I owned the Instapaper client, then upgraded to an Android phone. I promptly switched to another service with support for my platform.
A lot of people get tired of their dissertation research, and I've heard others contemplate contrived reasons not to finish their PhD.

This happens to be especially far-fetched... but it takes a "big" reason to justify to yourself that you may leave behind so much work.

I hope the author realizes that this particular scenario isn't one of the 1,000,000 biggest concerns for humankind... that he continues his research program, and that he finds an application of his research that has a positive impact in a much more likely scenario.
"The best solution is to not need money. The less you need investor money, the more investors like you". That's true if you are dropbox, airbnb and other startups that have a solid revenue avenues other than advertising. If twitter or facebook itself had been founded after that disastrous ipo (facebook ipo) they would be in a worse position than dropbox or airbnb in terms of funding and revenue. That said, i think facebook will get to its intended valuation within this year.
But she did not flee. She engaged and escalated. He attempted a 5 second caveman courtship, and she responded to it, teasing him about his wife to check if his testosterone really was turned up to 11. Soo-prise, it was! Maybe even 12. So then she teased him about his daughter, to see if he would virtually castrate himself to impress her. Soo-prise, it turns out Mr. Caveman does not live to sexually impress his daughter.

What she should have done was to record his overtures for public amusement, then turned her back on him.

> This is the sort of thing the people that want to "disrupt" the music industry don't understand, they think that artists not getting 100% of their music sales is a terrible thing, what they don't seem to understand is there's a reason the music industry takes a big cut.

People drastically underestimate the difficulty that is present in industries other than their own.

Engineers/Programmers are notoriously bad at this. Disrupt Education/Hollywood/Music/Movies/Medicine/Everything!

Now, they will eventually be proven correct (anything that can be defined; can and will be automated), but it is the systemic underestimation in difficulty that's the problem.

Doing well in any industry is hard, and most people don't understand that when they only have the facile prejudices of various industries to rely upon.

Things are broken, yes. People will fix it, correct. But it is not nearly as easy as people like to think it is.

Coders scream in shock and horror when people call them nothing more than code monkeys (which they obviously aren't) or when people state how easy programming is compared to generating a brilliant idea (it's obviously not).

But coders will scream just as loudly that others aren't very bright, smart, worthy/aren't doing work in their industry correctly.

Things are harder to do than most people, including you or I, can possibly anticipate without the requisite domain knowledge.
Note incidentally that I'm talking about the performance of the IPO, not the performance of Facebook itself. I think Facebook as a company is in a strong position. The problem is simply that Mr. Market (http://en.wikipedia.org/wiki/The_Intelligent_Investor) doesn't think so at the moment.

It's very possible that the Facebook IPO came early enough in this bubble to actually prevent a huge disaster. I did not like where things were headed with most startups in the past couple of years. The Facebook IPO was like a fire extinguisher that happened to contain a small fire before it got way too out-of-control.

If your startup has no business model, you better think of one fast. If your startup has no revenue or a lack of it, you better start generating a lot more really soon. If your startup has a solid business model and is cash-flow positive, it's time to start leap-frogging the competition and adjusting the course. This is the time when good companies become great ones.
