8 sins of the stupid smart person
In Why Smart People Can Be So Stupid, Robert Sternberg, from Yale let a Harvard researcher David Perkins write a chapter.Holy cow. But that's not the news. it's that Perkins says that you can be really smart but not know when to engage your smartness. Yup, he's got me figured out.
Perkins highlights eight deadly sins of the stupid smart person but I'll only admit to one of them. or maybe two. I can't decide. . .
- impulsiveness (doing something rash)
- neglect (ignoring something important)
- procrastination (actively avoiding something important)
- vacillation (dithering)
- backsliding (capitulating to habit)
- indulgence (allowing oneself to fall into excess)
- overdoing (like indulgence, but with positive things)
- walking the edge (tempting fate)

First ABS parts printed
This happens if you print ABS in too high layers and/or with a too low temperature (not sure what was the reason here we changed both the temperature and the filament width setting in the skeinforge scripts in the next run that was more successfully). Here we just took the HDPE parameters but extruded ABS instead. You can easily peel off layer by layer. While this is no good for objects it would be a good choice for support material as adrian noted somewhere on the forums (i think).

First ABS parts printed
Great news. Astera is back from the Last HOPE in NY and brought some ABS directly from the source - Zach's RRRF store :)
The left part was printed with ABS while the right one was printed with HDPE some time ago - they should be both the same object the extruder lost grip after one third of the ABS part. As you can see the bottom curls far less...as expected but still cool.
The bottom of the ABS part is a little black because of the base we use for printing - The cardboard boxes some IC company (on semi) uses to send samples in - I think they are covered by a thin layer of carbon that seems to help the ABS stick.

ABS vs. HDPE cylinder
Two hollow cylinders. On the left printed with ABS and on the right with HDPE. Unfortunately the Y-axis stepper motor seems to loose steps (lots of em actually) so the ABS version looks worse although it's Z resolution is far better because the ABS does not seem to grow larger after it leaves the nozzle. With a 0.4mm nozzle hole we get a 0.43mm filament.

The Birth-Control Extremists
Young, single men terrified of unwanted pregnancies, and sick of condoms, are turning to vasectomies for liberation.
"Now I can never have a girl say I made her pregnant," Whitlock says. "I don't have to worry about being tricked." Or "oopsed," as some advocates of vasectomy put it—as in "Oops, I guess that was a breath mint, not a birth-control pill."

One hot summer morning in July, 2008, a strange ginger cat appeared on 4chan. No one knows exactly where this cat came from, but before long the thread became epic and Raptor Jesus intervened to prophecy that the strange ginger cat was indeed Olngact, the third member of the holy Longcat family and one of the keys to world peace. Olngcat represents Fire.

Does anyone else remember this?
I had such a crush on Bridget Michele (the blonde) when I was a kid.
It's weird to see this now. I must have been around eight. The actress is now 42 years old.
