Comment Re:Why Not Regular Printers? (Score 1) 67

Got a link for that? I've been considering a second smaller machine for metal-working.

Screw drive machines aren't easily expanded to 1.2m x 1.2m --- it only cost ~$60 to extend my Y-axis to 1m, and double up the MakerSlide on the X-axis --- much more solid, but admittedly, still a bit fiddly, but for the price, it meets my needs thus far.

Comment Still a long way to go (Score 1) 67

I tried to put together a B.O.M. @ kitbom.com: http://kitbom.com/WillAdams/reprap-morgan and it currently prices out @ $274.26, not including the 3D printed parts and some things we've not found good sources for.

Also, free software for 3D CAD/CAM still needs a lot of work --- I've listed everything I could find here:

http://www.shapeoko.com/wiki/index.php/CAD
http://www.shapeoko.com/wiki/index.php/CAM

and people still over-whelmingly choose commercial software:

3D CAD 9/15 --- http://www.shapeoko.com/forum/viewtopic.php?f=6&t=1783
3D CAM 19/37 --- http://www.shapeoko.com/forum/viewtopic.php?f=6&t=1785

(by way of comparison the commercial stuff is listed here: http://www.shapeoko.com/wiki/index.php/Commercial_Software )

Please tell me I missed a fabulous opensource solution, or some much less expensive parts....

Submission + - Melbourne Restauranteur Promotes Addition of 'Th' Key (theage.com.au)

Submitted by beaverdownunder
beaverdownunder writes: Melbourne restauranteur Paul Mathis has developed a one-character replacement for the word 'The' – effectively an upper-case "T" and a lower-case "h" bunched together so they share the upright stem – and an app that puts it in everyone's hand by allowing users to download an entirely new keyboard complete not just with his "Th" symbol, but also a row of keys containing the 10 or 15 (depending on the version) most frequently typed words in English.

Mathis has already copped criticism on Twitter (one correspondent called him "a crazy arsehole") from people who claim he is attempting to trademark a symbol that is part of the Serbian Cyrillic alphabet (pronounced "tshe", the letter represents the "ch" sound found in the word "chew").

Submission + - Why are Japanese men refusing to leave their rooms?

Submitted by fantomas
fantomas writes: The BBC reports on the Japanese phenomenon of Hikikomori: young people, mainly men, who are holed up in rooms in their parents' houses, refusing to go out and engage with society. Why is this happening? and is it a global phenomenon or something purely due to Japanese culture? (we're all familiar with the standing slashdot joke of the geek in their mom's basement for example)

Submission + - New Study Fails to Show that Violent Video Games Diminishes Prosocial Behaviour (ausgamers.com)

Submitted by trawg
trawg writes: A new Australian study on the effect of violent video games on Australia has just been published, failing to find any evidence that playing video games affects prosocial behaviour. The study compared groups who played different types of games, including notably violent titles like Grand Theft Auto and Call of Duty, as well as non-violent titles like Portal, comparing their behavioral response through a simple pen-drop experiment. In a follow-up interview, the researcher noted his perspective on how violence might affect people has changed since he started the research:

I’ve played video games for most of my life and got into this research because I couldn’t believe that violent video games could make me do something I didn’t want to do, that is, be aggressive. My attitude has changed somewhat. These days I find it totally plausible that violent video games could influence people’s behavior, but the real question is whether their influence is harmful, and I’m not yet convinced of that.

Submission + - Discrete Log Problem Breakthrough Threatens Crypto

Submission + - Harlan: A language that simplifies GPU programming released (paritynews.com) 1

Submitted by hypnosec
hypnosec writes: Harlan – a declarative programming language that simplifies development of applications running on GPU has been released by a researcher at Indian University. Erik Holk released his work publicly after working on it for two years. Harlan’s syntax is based on Scheme – a dialect of LISP programming language. The language aims to help developers make productive and efficient use of GPUs by enabling them to carry out their actual work while it takes care of the routine GPU programming tasks. The language has been designed to support GPU programming and it works much closer to the hardware.
