then after seeing 6.00 one might wonder what the point of all that update fuss was about
If you want to see what Skype said about the 6.x release, you can read this: [^]. They claim improved audio and video, with this version, on their website.
“Thus on many occasions man divides himself into two persons, one who tries to fool the other, while a third, who in fact is the same as the other two, is filled with wonder at this confusion. Thinking becomes dramatic, and acts out the most complicated plots within itself, and, spectator, again, and again, becomes: actor.” From a book by the Danish writer, Paul Moller, which was a favorite of Niels Bohr.
I've seen one of those systems in east Texas many years ago. I find it hard to believe that with all the friction involved they could be all that efficient. Most oil field pumping units are driven by relatively small motors, since when properly adjusted the counter weights pretty much balance the rod load for each individual well on modern systems. (Part of my research involves numerically modeling oil pumping systems.)
On the other hand, the wells in those days were relatively shallow. I doubt they would work on most wells these day, aside from being a mile or more deep, you'd also have to make sure that safety regulations are met and that cos, etc. don't mess with them.
Still, it's interesting to see how much ingenuity was involved in figuring out how to solve problems in eras gone by. I saw a primitive system in Indonesia where they lowered a cable into a well and pulled it up by hand to get the (thick) oil that stuck to it. Hardly efficient but labor was cheap and the market for the oil was for local cooking, etc. Ingenious technique with limited resources when you think about it.

A restaurant near here uses a similar system for its ceiling fans, there's one motor and the rest are connected by a series of pulleys. It's interesting to see alternative ways of accomplishing things we take for granted.
It reminded me of a commercial for Kayak.com where one guy was sitting on the couch with two dummies on either side of him. They are all connected by wooden rods, and typing on their own computers to to "search multiple sites for the best travel deals..."
Debugging is twice as hard a writing the code in the first place. Therefore, if you write code as cleverly as possible, you are, by definition, not smart enough to debug it. --Brian W. Kernighan
I've spent a couple of weeks now with VS2012 and have found the only really, really annoying thing is the new dialog which replaces the old Find in Files dialog. Does anyone know of a way to make it more like previous version of VS?
