If you allow children to watch movies like the Expendables, you're part of the problem.

My kids didn't get to see much in the way of action/violent films or shows until they were in their mid to late teens. As I often say "Why the taboos on sex, and not on violence? I hope my children have sex some day, and I hope they never have to kill anyone".
Not that I let them watch porn, either ;)

Mostly they grew up with mythbusters, documentaries, science shows, and a freaking ton of books.

Comment Late 1989, on a VAXstation II/GPX (Score 1) 204

Late 1989, on a VAXstation II/GPX running VMS 5.0. Not exactly a desktop workstation, it was a desk-side box as big as a 2-drawer file cabinet. That newfangled DECWindows came out and killed off the old VMS GUI "VWS". Right about that same time the VAXstation 3100 came out, a true desktop VAX workstation...

The early versions ran a "desktop" called "XUI", which was replaced with Motif in 1991.

Another commenter wrote that the performance has not improved that much since the early 90s. My current desktop Linux box has the equivalent CPU horsepower of 10,000 VAXstation 3100s, but it boots to the login window only about twice as fast. Progress?

Sun stood on the shoulders of giants.

That 68000 processor that Sun used? Modeled after DEC microprocessors. That ethernet wire they connected to? They don't call it Digital-Intel-Xerox Ethernet for no reason. That "new thing" unix Sun used? And the C language? Built on DEC PDPs. Your terminal emulator? Emulates a DEC terminal. USB? A consortium, including DEC. That X-Window System sun used after NeWS tanked? Yep. Came from Project Athena, sponsored by DEC. MIT & IBM.

One of the many reasons that DEC died was that many people in the company were blinded by the brilliance of VMS and the layered products, and could not understand why anyone would want to settle for less. Digital had stuff in the 80s and 90s that the rest of the industry caught up with 10 or more years later, and in some cases, have still not caught up. The problem was that DEC's stuff was very, very expensive, and very proprietary, and DEC was out-marketed by other vendors selling supposedly "open", and certainly cheaper unix based solutions (See "snake oil".)

Comment ultra low latency over microwave and laser link (Score 2) 137

not fiber. point to point laser and microwave links.

I believe you are referring to ultra-low-latency trading.

They prefer microwave links to fiber because the microwave signals propagate faster through air than light does through a glass fiber. Light travels through glass fiber at about 65% of c, which is also pretty comparable to the velocity of a electric signal in a transmission line (.65 to .75 c) (which is where Admiral Hopper ties in)

Microwave signals propagate though air at damned close to the speed of light, and the microwave signal paths are direct by necessity. That means the path can be significantly less than half the distance a cable (electric or optic) and the speed about 50% faster.

Optical paths are also used, they are by laser through the air. This has the same direct path, near c speed advantages as microwave.

systemd is best avoided. Avoid! Avoid! Avoid!

(pulseaudio, avahi, systemd. Why are these things all such a f*cking bear to deal with? Why, oh why?)

CentOS might work for you, if you don't feel the need to be completely modern. No systemd in Centos 6. I expect to see in in RHEL 7 / CentOS 7, though.
