Printing to the console

Submitted by uneek
uneek writes "Why is printing to the console such a bottleneck? Applications that do not print to the console are at least 30 times faster than apps that do. This seems to be the case in both windows and linux."

Computer architecture for toddlers

Submitted by uneek
uneek writes "I have a computer that is broken that is about to be dissected for educational reasons. I would like to find a book, targeted at six year old / kindergarten reading level that talks about the parts of a computer using both pictures and words. I would like my child to take good guesses at what parts are as we take them out.

Does anyone have any recommendations?

Thanks"

New LLVM Debugger Subproject Already Faster Than GDB 174

kthreadd writes "The LLVM project is now working on a debugger called LLDB that's already faster than GDB and could be a possible alternative in the future for C, C++, and Objective-C developers. With the ongoing success of Clang and other LLVM subprojects, are the days of GNU as the mainstream free and open development toolchain passé?" LLVM stands for Low Level Virtual Machine; Wikipedia as usual has a good explanation of the parent project.

Simulation of Close Asteroid Fly-By 148

c0mpliant writes "NASA and the Jet Propulsion Laboratory have released a simulation of the path of an asteroid, named Apophis, that will come very close to Earth in 2029 — the closest predicted approach since humans have monitored for such heavenly bodies. The asteroid caused a bit of a scare when astronomers first announced that it would enter Earth's neighborhood some time in the future. However, since that announcement in 2004, more recent calculations have put the odds of collision at 1 in 250,000."

by uneek (#29994602) Attached to: Low-Energy Laser Etching May Replace Fruit Labels

Burning the skin of a grapefruit with a laser may be ok, but here are some questions:

1) With the laser burns, it may be possible to cover up blemishes or signs of mold or rot on the skin of a fruit.

2) What happens with apples, potatoes, carrots, pears, and other fruits and vegetables where its good to eat the skin? I don't want some artificial chemical imprinted into the skins that I would normally eat.

I always know a label is there, I know to take it off. For fruits and vegetables with skins that are supposed to removed, the label is not a problem because I peel off the skin.

So this technology does not really solve anything, and it becomes an inconvenience.
