e.g. I fondly recall the use of the 'Haversine formula' (calc. distance on a sphere with given lat, lng) built in SQL, instead of using one of the available Geo ruby libraries/ gems (although I'm not sure, if those gems were available back

Really like Michael's clear writing style (remember reading Railsspace back in 07). Thx for this new resource. Also like the fact that he doesn't use many gems, but discusses building stuff from scratch (regarding Railsspace book).

Back a while ago I submitted an idea, that maybe there are herd (mob) effects on comment threads happening. This should do the trick (driving the long tail).

I don't mind talking about trees. The bigger picture behind this concept is urban planning, which is a huge issue to be fixed in the U.S. (if you want sustainable development).

Hmm... there is a point where principle matters more than money. A company is not just a chunk of cash... how can you motivate people to spend their life with a company when it's just a payout? I grew up in Europe and there is something abo

Yup. That's why I moved to Canada for a while at least. Want to try out the so-called freedom you guys in North-America have. Pros and cons. EXAMPLE: 1/2 h ago somebody stole my mountainbike right out of my garage. Here in North America nob

The U.S. needs the technologies and the explicit and implicit fabric of rules that Europe uses to govern people in crowded areas (hint: it works! go on a visit). Individualism doesn't work anymore in the U.S. - not in litigation, healthcare

Don't agree! I've cracked down on eating out for a month and lived off pasta and vegetables. You can't get a meal for $3 at McD. but you can eat for $ 1 for the day making your own food. It's an interesting experiment! This excludes meat an

Agreed, most of these discussions lack rigor.

No, Economics is very much part of the picture. Economics is not philosophy or religion but optimization under conditions of scarcity. As long as we remain metrics driven there's nothing wrong with talking optimization. My two cents.

Well put! The basic models of Econ were built on physics envy. They built models on a fairly artificial set of assumptions that use calculus. Poppycock.

Hmmm... with break-throughs in current materials science, like super light-weight composites, there might be a way to build a structure strong and light enough. Would be a cool project for a research lab with funding and people.

As I understand - the issue is that WordPress allows in-browser editing of PHP code. If you only allow people to edit standard HTML, then this issue would go away.

Seconded - this is a million dollar idea! Well defined niche, great product, very useful, very catchy name and branding (totally straight forward) - can't get any better than this. Not sure how hard it is to create a Mac OS X version as wel

Agreed. It took way too long for economists to integrate cognitive bias and social effects on rational decision making. Further, they have traditionally not integrated tools from analyzing networks, common in complex systems analysis. Econo

No, in the example on this thread Laurent, a Belgian programmer, charged $ 500 USD for the whole solution, the whole shebang. (He could have just given it away for free, since the main point was to establish a reference) Although, I admit..

Well, Laurent charged only $ 500 USD for his solution (but that's an anomaly). If you are serious about web apps, then scaling the back end comes into play, which means getting into distributed systems. Networking, security and SysAdmin bec

That's in british pounds, not USD. Addition: did the math at www.oanda.com (currency conversion). GBP is LESS than what I thought: 1.63842 USD. So, that's 900 bucks a day, resulting in $ 110-120 USD/ hour.

You made a triple-language supported database application with immaculate crisp graphic design and well thought-out layout for $500 dollars??? Your solution btw is about as good as it gets for a small-biz website. I second the opinion that

Yahoo! was initially a funny spelling before people got used to it. Same with the word Google (before 1999 I would have not known how to spell that).
