GeneralRe: Space Shuttle: $1.5 billion per flightmemberClifford Nelson5 Nov '12 - 14:25 
The tiles made it work with current technology. They wanted to get the Shuttle off the ground, so sometimes had to just make it work. That is the problem with not building demonstrators. You cannot test any of the technologies for the final product without having whole design work.

There is very little from the space shuttle that probably was used on the Delta IV. The Delta IV is the latest of a long line of Delta boosters that have one of the longest histories with a 95% success. In the first decade of the century there were two partial failures of Delta rockets where the satellite was not put in the correct orbit (http://en.wikipedia.org/wiki/List_of_Thor_and_Delta_launches_(2000%E2%80%932009)[^]), one the first launch of the Delta IV Heavy.
 
It is well known that the tile system was not a good design (http://www.keithcompany.com/Article%201-23.aspx[^]). There has been some work on other options (http://en.wikipedia.org/wiki/Atmospheric_entry[^]), but I guess without a future space plane in the works, probably not a lot of work has been done on the concept. I would guess that a lot of the reason for the shuttle's economic failure comes from the tiles (it was suppose to make space flight cheap).

It's only about 3 USD per citizen, so it's maybe 1 free burger. Laugh | :laugh:

Did you ever see history portrayed as an old man with a wise brow and pulseless heart, waging all things in the balance of reason?
Is not rather the genius of history like an eternal, imploring maiden, full of fire, with a burning heart and flaming soul, humanly warm and humanly beautiful?

Couldn't see why this was 2-voted. Countered.
I think computer viruses should count as life. I think it says something about human nature that the only form of life we have created so far is purely destructive. We've created life in our own image.

NewsTaking Password Storage Up A NotchstaffTerrence Dorsey5 Nov '12 - 11:14 
There are too many databases in the world with completely unencrypted passwords. Even when databases have encrypted passwords, they typically do not implement protection that is strong enough to keep them from being stolen, and used maliciously. With the advancements in computing technology, we now need another approach to store passwords and keep them safe from prying eyes. Fortunately, you don't have to be a cryptography expert to use good password protection.
Protect your users, take password management seriously.
NewsScrolling or paging?staffTerrence Dorsey5 Nov '12 - 11:13 
The new version of iBooks allows you to read books in a continuous scroll instead of page by page. This has, surprisingly, set off an argument on which is the better way to read an ebook. I don’t get it. Paging is clearly an artifact of the technology of paper books, a technology I love deeply, but one that doesn’t make a lot of sense in an ebook reader.
What's your preferred method of reading ebooks?
GeneralRe: Scrolling or paging?memberClifford Nelson5 Nov '12 - 14:28 
I think that paging has the advantage of being able to maintain your place on the screen by location on the screen. Interestingly, ancient scrolls did not have pages, so are we going back in time? Obviously doing scrolling has the advantage of not having to move images so that they can be fully displayed on a page.
