Logged in to make this comment. People have been doing this for a long while. Over at you can find dozens of people who've built their own machines as well as links any and all material that you might need to buy. And they build all types of machines from 8-axis titanium milling to 2-axis wood routers. It's a fairly big hobbyist industry.

Better Development Through Competition? 251

Posted by Soulskill
from the there-can-be-only-one dept.
theodp writes "Among the tips Derek Sivers offers for how to hire a programmer to make your ideas happen is an intriguing one: hire more than one person to complete your first programming milestone, with the expectation that one will go bad, one will be so-so, and one will be great. 'Yes it means you're paying multiple times for this first milestone,' says Sivers, 'but it's worth it to find a good one.' It's not a new idea — the practice of pitting two different programmers against each other on the same task was noted three decades ago in Tracy Kidder's Soul of a New Machine — but one that never gained widespread acceptance. Should the programming code-off be adopted as a software development best practice?"

A Close Look At Apple's A4 Chip 245

PabloSandoval48 writes "Apple's A4 processor is heavily influenced by Apple's long-established relationship with Samsung and represents an evolution rather than a revolution in circuit design. A team of experts takes a look at the evidence on A4 in an attempt to determine its origins and the influence of recent Apple acquisitions in the area of chip design."

US Dept. of Energy Wants Bigger Wind Energy Ideas 252

coondoggie writes "The Department of Energy wants to kick up the research and development of offshore wind projects as it looks to achieve its goal of producing 20% of the country's electricity from wind farms by 2030. The DOE Wind Program is looking to focus on what it calls specific advanced technology, gigawatt-scale demonstration projects that can be carried out by partnerships with a wide range of eligible organizations and stimulate cost-effective offshore wind energy deployment in coastal and Great Lakes regions of the country. The agency is also looking for more research that can help address market barriers in order to facilitate deployment and reduce technical challenges facing the entire industry, as well as technology that will reduce cost of offshore wind energy through innovation and testing."

First Self-Replicating Creature Spawned In Conway's Game of Life 241

from the emergent-gameplay dept.
Calopteryx writes "New Scientist has a story on a self-replicating entity which inhabits the mathematical universe known as the Game of Life. 'Dubbed Gemini, [Andrew Wade's] creature is made of two sets of identical structures, which sit at either end of the instruction tape. Each is a fraction of the size of the tape's length but, made up of two constructor arms and one "destructor," play a key role. Gemini's initial state contains three of these structures, plus a fourth that is incomplete. As the simulation progresses the incomplete structure begins to grow, while the structure at the start of the tape is demolished. The original Gemini continues to disassemble as the new one emerges, until after nearly 34 million generations, new life is born.'"

Adding features does not necessarily increase functionality -- it just makes the manuals thicker.
