> Sea water is incredibly powerful and corrosive.

I'd point you to the Maunsell Sea Forts. Every single one has survived ~70 years in the open ocean, the ones that haven't were plowed into by boats.

My suggestion is specifically to be a giant sea fort, and to build inside of the column and above it. My idea would be to go ridiculously large and create a second interior wall after sinking as a sort of levy from the true interior in case the exterior is damaged.

I think a good 100 year zero-maintenance survival of an ocean arcology is amazing. Beyond initial construction the idea would be to expand and build a harbor, which would further expand the lifetime by taking any mechanical wear off of the main structure and place it onto the harbor walls.

Furthermore, if you had a crane on one of the towers (which would be mandatory if you're building as you go) it would be a simple matter to move soil around in the water to create an artificial reef.

The real problem would come with what materials to use for construction of the rest of the arcology. If you go with steel, it means you're going to require a lot of maintenance because of the sea air. It has longevity, (think all oil rigs) however it won't last forever. However, if you go with aluminum it will genuinely last for ever. The oxidization rate for aluminum is pitifully small (I work with it, I know, we remove 3/16ths aluminum that has only begun chalking after 40 years - which is the coloring coming off, the metal itself is like new). However, you'll never be able to use steel on the structure in the presence of salt water. Even insulating them won't work if the joints are capable of being covered in ocean spray as the galvanic reaction will eat the aluminum as aluminum is used as a sacrificial anode for steel.

Impressed Current could be used, but that would mean electrifying your entire superstructure, which would defeat the point of making your arcology survivable.
Has the ever-growing number of free, low-quality web pages made it pointless to sell stuff on the Internet? </rhetorical>

I love free competitors. They make excellent places to place ads. ("Want to try a solution for this that doesn't suck?")
Decoding obfuscated Javascript
I've avoided posting because there's really nothing more to say, but c'mon! Are you really comparing yourself to Jerry Yang? That was in the 90's and he was one of the first. That bus has come and gone. Just like if I put up a list of my favorite links. No way in hell is that going to turn into allenslist.com and make me a million bucks for doing nothing.

There is way more competition now. Listen to what people are telling you.
We use the purchased version of Google Apps, and while it is slightly better than the free gmail we still get a lot of slow searches on the web interface or instances of "unable to load conversation" when trying to view mail.

One of the greatest selling points of Google Apps for us is having all previous mail archived and search-able so this is somewhat disappointing, but the total search time + time spent retrying is still less than the total search time would be using 10GB of mail in Outlook.
Agreed. This is a much better argument for Facebook being 'closed.'
I think this is a cognitive bias caused by, e.g., me not rushing to the front page fifty times in the last four years saying "Guys WTF Paypal just paid me a thousand dollars on time with no hassles."
Yea Google is about 3-4 years too late of when this could have affected Facebook.

As a college student juggling far too many small contracting jobs, a 15 hour/ week part time job, and a relatively intense courseload, I find myself saying similar things. I could drop out, quit my part time job, and probably make significant money consulting/contracting. Yet something inside me says that would be meaningless.

Ask HN: To kill or not to kill an Adsense account
I've got an Adsense account with a modest amount of money in it from when my site was using Adsense. Now my site is part of the Yoggrt network, so I'm not using Adsense on any part of my site, and I don't have any plans to use it in the near future on any other sites. Unfortunately, my Adsense account doesn't have enough to cash out (<$100), but I can get the money out if I close the account.

What would you do in this situation? Would you close the account to get the money out, or just leave the account open in case I want to run Adsense again? If I close the account, does anyone know if you can get a new Adsense account in the future?
The main problem with JS "this" is that in a language where everything else is lexically scoped, "this" is dynamically scoped -- taking the value of whatever object the function happens to be attached to at call time. To use a Ruby metaphor, imagine if "instance_eval" were the default way to call a method.

One of the main features that CoffeeScript adds to help with "this" issue is the bound function literal (the fat arrow). A regular function looks like this:

add = (num) -> this.value += num

And compiles into the regular JavaScript you'd expect:

var add;
add = function(num) {
return this.value += num;
};

However, if you define the function with a fat arrow instead:

add = (num) => this.value += num

You'll get a function bound to the current value of "this", and when you pass the function off to another object as a callback -- a DOM event handler, or success callback from an Ajax request -- the value of "this" doesn't change.

Here's perhaps a better example, from jQuery:

var self = this;
$(".row").bind("click", function() {
this.setText("Clicked!");
});

And in CoffeeScript, without the "self = this" bit:

$(".row").bind "click", =>
this.setText "Clicked!"

There are many different approaches to Tai Chi - from the 'spiritual', via 'health', the 'form', 'weapons', 'push hands', ... , all the way to 'tournament fighting'. I've just come home from a lesson where we had to wear chest protectors...

But one thing that I've heard, and I kind of agree with : I don't recommend Tai Chi to anyone. If someone wants to do it, then I'm happy to point them in the right direction. But I don't want to push people into something that they're only going to try because I've persuaded them. They've got to have an inkling that it's something they'd enjoy.

I had previously do some Jiu Jitsu (cool), and Aikido (v. nice). But what's kept me doing Tai Chi is the fact that my shoulders don't get dislocated so often (YMMV - but it's notable that many of the students at my school are musicians that have consciously chosen a martial art that won't damage them).

Another point is that while one can feel 'dangerous' more quickly doing other martial arts, that is usually an illusion : being an over-confident beginner is much more likely to get you in trouble. Tai Chi students doesn't suffer from that so much - since for the first few years, they're only directing traffic in the park :-)

I originally started in 1999 because I figured I needed some external activity to take my mind off my startup - and the health stuff has been a pleasant side effect. Mostly I do Push Hands now, with a dash of mornings in the park helping others 'tuck in'. ( ChuTaiChi.com )
Here's one idea: Does anyone know if you can directly fund an Adsense campaign from money in an Adsense account? If so, I could save it for an ad promotion for future products, and keep the account for now...

Here's another vote for Brazilian Jiu Jitsu.

It's also good to be able to fight pretty much full-force in training as well - which you can't really do in a striking art.

Ok Patrick, here goes. I do not know your entire situation and i would like to start off by saying I am no "expert" in the field of UI or UX, but I can tell you that your site has some usability issues that you said you were going to address which is a good thing, but you need to do that sooner rather than later.

As someone who has been down this road (and yes I was turned down by Ycombinator tuesday too) I know that hardly anyone succeeds the first time they try something. The idea itself may succeed in the long run, but the implementation must change for it to work. You NEED to know that.

If you are dead set on your ideas working as is you will probably never have them actually work.

Keep in mind that everyone feels that their idea is wonderful and it will succeed, I believed that so much to the point that I took jobs selling cars on the weekends and working at geeksquad at night just to pay my bills while trying to make it. Ultimately I did so, but I would argue it was the tenacity I had that made my success a reality (I was also very lucky like most entrepreneurs). If you are not willing to do anything and everything it takes to succeed including eating cans of soup 1/2 can at a time in order to stretch meals out for several days and sleeping on your bedroom floor because you sold your bed on craigslist to pay your server bills chances are you are not the kind of entrepreneur anyone is interested in investing in.

Listen to some of the stories of the guys who made it but just barely. My recent favorite is Brian Chesky who is one of the founders of AirBnB ... truly a teriffic story where they believed in their idea enough to sell CEREAL to make a software company stay alive.

That my friend is wanting it and THAT is the kind of spirit and tenacity that the "deep pockets" in SV are looking for.
A lawyer isn't necessary, file a small claims action against them in your local area. If you're a writer you claim jurisdiction where you work (like the poster of this thread did), which generally means the other person will never be able to get there. They're either hiring a lawyer/paralegal to go to court or they sit and wait for the court to order payment.

Personally, I'd be filing small claims against them on the order of a thousand dollars or so and include a claim for expenses. Good chance it's job done and you got the cash.
Does it mean anything in particular that they chose the Apache 2.0 license? Their previously public plans were to use MS-Pl.
AOL, Yahoo, and Hotmail all provide contact APIs. The amount of traffic Facebook generates would be unmistakable and Google would just block them.
Seconded. Word processor isn't any better than text editor.
Just got through installing Ubuntu.

I expect to see some really good software come out of this. I think Microsoft bought a lot of goodwill with the community with this move.
I would recommend you do two things:

1) Create one app to throw-away - something that's simple, useful to you, and which you are confident you can create. Don't worry about there being hundreds of similar apps. This is your Learner app. Get it together in a few weeks and put it on the app store for $1-$2. Make sure you have some "please leave a review / send email" link that makes it a no-brainer for people to give you feedback. Read them all, but learn to distinguish between genuinely useful suggestions, and comments from people who feel your app really needs their pet feature.

2) Find a need that you think people would pay $3-$5 for, preferably a need that you yourself have, and work on that app using everything you learnt in #1. Get something basic but polished out, then iterate.

General tips:

- Polish is more important than features.
- Ensure you get 6 friends to buy & rate your app (5-6 is the minimum you need for a visible rating).
- Launch at $1 for a week, and cut the price to $1 for a week for every update. It does make a difference IME.
- Read the descriptions of top apps and see how they sell themselves.
- Read the reviews of apps similar to yours and see what people are missing.
- Make it easy for people to send in-app email for support questions. Be the best support person they've encountered. Happy users recommend your app and leave very nice reviews (particularly if you ask for the latter after helping them).

Java is Oracle stack, C# is MS stack, objective-C is Apple stack.

Is there an opportunity for an open language with similar VM ease-of-use/performance tradeoffs - or is hardware now fast enough for the ease/speed of dynamic languages to fill that gap (Python, Ruby, Javascript, ...)?
Seconded - Tai Chi is amazing. I used to do it when I was much younger, and I like to think it's the reason I have such good balance, and I stay coordinated when drunk. :)

I've been looking at starting up again. Anyone have any recommendations for a good teacher in San Francisco?

Every startup has the chicken and egg problem -- It's worth a million dollars, but only if it had the customers/dollars/advertising/partnerships to make it succeed.

You've obviously got belief and vision for the project, which are great traits to have. But consider yourself being an investor. How do you calculate the ROI? Will giving you $500/week (peanuts) generate a future return of $1,000/week or $20,000/week, or maybe just $10/week? Investors are business people, so they need some way to guesstimate a ROI. If I sponsor you, then how can you convince me that I will at least break even on the investment within the next 2 years?
As others have kind of hinted, you seem to have the cart before the horse. What are you passionate about? What problem is constantly bothering you?

Once you find the "better mousetrap" (at least, conceptually) then the question is, how can you build it for $3k/month and make $5k/month.
Well yeah it was petty nonetheless, but jhamburger is suggesting that the editor here is essentially trolling the author and more than anything I was trying to say I didn't really think that was happening.

It really depends on what you want to get out of it, if you want street defense then there is really nothing better that Jiu-Jitsu or Aikido. I like small circle Jiu-Jitsu out of all the Jiu-Jitsu disciplines, but it is hard to find schools. Brazilian Jiu-Jitsu is a good art just keep in mind that it has been adapted over the years to focus on competing in MMA tournaments. As such it has eliminated a good deal of knowledge about small joint manipulation and breakage, which in a street fight is invaluable. There are others like small-circle that still retail small-joint along with weapons disarmament.

For sport and limberness Taekwondo is a good choice, as well if you want to compete at some point but dont like the idea of getting pummeled, Taekwondo is the largest point sparing art. Point sparing is not fighting, it is a sport where you achieve points for landing a strike, it is fully padded and once a blow is landed the opponents reset and start over, it is similar to fencing. Just keep in mind, it does not prepare you to be a well rounded street fighter.

Aikido is an awesome art that is very effective in street combat. You do not see it in UFC style fighting because it focuses on small joint breaks, pressure points and a good deal of stuff that is outlawed in the sport of MMA for obvious reasons. None the less it is extremely effective and can be deadly when mastered. It is also the art that takes the longest to achieve mastery.

Kung Fu is very philosophical and is one of the oldest arts, some of it is not as practical as more contemporary arts but it has value in exercise and meditation.

Honest opinion, I think that Judo, Kempo and most of the other arts are not well rounded enough to focus your time on. Jiu-Jitsu covers Judo and more, Boxing or Taekwondo or better striking arts than Kempo and its joint techniques are inferior to Aikido or Jiu-Jitsu. Most of the other Karate based arts kind of fall into the same trap, other arts have surpassed them.

The only other ones I can think of are muay-thai which is a good boxing art, I think Taekwondo has better kicking form but muay-thai has better hand boxing and knees and elbow strikes.

The other would be Jeet Kune Do which was Bruce Lees art and combination of disciplines. It was a very interesting art but the reality was that it was 1. unfinished and 2. all of the masters are deceased so the art has for all intents and purposes died. While Lee documented it, learning technique from a book never suffices for the real thing, and all of the masters today have learned from the reconstruction of techniques in the book.

I compared changing the Apache MPM, Varnish & nginx for a high-traffic, low memory (256M) server.

* Changing Apache would have required changing other packages - PHP wasn't thread-safe.

* Varnish looked fragile. I wish I still had my notes about why I thought that.

* Nginx in front of Apache was relatively quick to setup & really great in practice - restarting an order of magnitude less often.

If the nginx config file would be useful as a starting point, I offer it.

The switch from the previous device caps model to HiDef/Reach means that games cannot opt to run on any windows machine that supports the GPU features they require, or choose to scale their experience down based on available features. If you select the HiDef profile, your game will fail to start if any of the features in the profile are missing. Likewise, the Reach profile prevents you from using HiDef features, so you can't target any of the millions of PCs that occupy that space in-between (for example, anyone with an Intel GPU). While it is theoretically possible to ship a PC game using the Reach profile, the profile is so absurdly limited that you'd be insane to use it for anything larger in scope than a 2-week project.

Another data point - I trained in Aikido for several years, and enjoyed it tremendously. I eventually moved away from my dojo and couldn't make it often enough, so I stopped, but I highly recommend it.

It's been particularly helpful in defending me "on the street" - it taught me to be really good at falling without hurting myself, which is an incredibly practical self-defense skill. It's come in handy many times on icy Michigan roads. I'm not looking to start a fight, and I've never been ambushed by ninjas, so striking arts haven't really appealed to me.

Capoeria looks like a lot of fun, too.
