Tidbit inspired me to write my own web-miner, which I open sourced. It's hacked together as I was really just trying to learn how the cryptocoin&mining stuff worked. The mining rate you get with straight javascript is truly abysmal, even with web workers (much worse than the standard cpuminer).
I found a couple examples that do the scrypt part with GPU in browser, but your browser has to support custom shaders, I think (I forget the details), and the version most browsers support doesn't allow this (again, my memory is sketchy about the details).
Anyway Here you go, NJ! https://github.com/borlak/cryptocoin_scrypt_stratum

Does Yahoo have a public bounty program?

You probably would if you travel, or go to conferences...

The top answer in that thread is excellent.
Basically, "it depends". having dealt with extremely DB-intensive applications, I have developed a personal motto of "be nice to the DB".
Let the DB be a secure storage of your data, not a calculating part of your application. But like the top answer says, sometimes it is not practical to do a calculation within the application. In my case, we had a few database servers set aside just for reporting, so we could slam them with difficult queries and not worry about affecting data.

He posted on a real person's wall with the initial bug report. It says right on the /whitehat page not to do that, and he mentioned /whitehat in his bug report, so he should have known.

What do you mean? The SWF progress bars are one of the few that can actually be relied upon. A good example: http://armorgames.com/play/12141/kingdom-rush
The Microsoft installation progress bars are the ones I remember as being ridiculous. Often going backwards, showing ridiculous install times, etc.

Also a bit problematic if you happen to roll your car over on its top...

It sounds like you want everyone to be a system administrator. That is not going to ever happen.
The human history of inventing has one very consistent theme: making things easier for ourselves. "Computers" will only become easier to use, and require less knowledge of the humans that are using them.
When "computers" go wrong, a human with that specialty will fix it. You have that specialty. Why can't everyone fix their own cars or HVACs or bake their own bread?

The main turnoff for me when it comes to Rails is watching other major companies like Twitter completely rewrite their application away from Rails.
Growing pains -- the kind of pains we all want to endure some day. If you are planning to grow, why wouldn't you start with something you know has an end game (like PHP or Java)?
The often cited slowness of Rails, mixed with companies rewriting their codebases, and the flurry of vulnerabilities in the past year has caused me to take Rails less seriously.

In the book "The Moon is a Harsh Mistress" (1966), an electromagnetic catapult is used to deliver goods from the Moon to Earth. It is similar to what you described -- just a really long tube (or rail) at the highest elevation possible.

I really wouldn't call this an alternative. If you are running memcached, it's very unlikely you can switch to Groupcache.
Parts of your application may rely on the expiration feature. But the biggest change is the inability to overwrite a current cache key. Every application I've used does this constantly (object updates).
Groupcache in its current form is useful for a very narrow set of applications.

I can give some examples but my point was basically you have to test for your specific desired user base, and these kinds of posts don't really mean much.
Some things that we did: autoplaying videos. enormous graphics and big text. lots of "as seen on !". landing page was probably 6000-7000 pixels high and the form was near the bottom.
On boot as it's loading players, their file descriptor ID was saved, so it loads it up and resumes talking to the socket. It also loads the ID of the server socket descriptor. No need to send information to a new process as it just loads the previous game state.
