Submission MIT's new design tool lets novices customize 3Dprinting in minutes->

jan_jes writes: Researchers now aims to change the time consuming design process, with a new system that automatically turns CAD files into visual models that users can modify in real time, simply by moving virtual sliders on a Web page. Once the design meets the user’s specifications, they can hit the print button to send it to a 3-D printer.

For a CAD user, modifying a design means changing numerical values in input fields and then waiting for as much as a minute while the program recalculates the geometry of the associated object.

Once the design is finalized, it has to be tested using simulation software. For designs intended for 3-D printers, compliance with the printers’ specifications is one such test. But designers typically test their designs for structural stability and integrity as well. Those tests can take anywhere from several minutes to several hours, and they need to be rerun every time the design changes.

So, we'll keep locking people in rape cages for growing plants, pulling guns on unarmed teens and going through security theater in air ports with a 90% detection failure rate....But finally I can do to vote on a bogus petition with no effect. My confidence is restored thusly.

... It's a lot more appropriate to compare the open sourcing of Swift to the LLVM/Clang projects than to Darwin. LLVM is by any measure a thriving open source project with lots of contributers, both individuals and from many large organisations (Intel/AMD/ARM/Google/Microsoft, etc. etc.). I also follow Webkit development to some degree and it's far from "the Google style of closed development followed by a public source dump", a fact that should be clear to anyone who takes a minute to look at the webkit-dev mailing list.

While there are almost certainly multiple factors at play (nutrition, environment, etc) it would be nice if we could all stop pretending to not understand one of the root causes of negative impacts on brain development - specifically spanking.

There are no studies that show spanking has any long term positive outcomes. There are plenty of studies that show negative correlation with long term negative outcomes. Just as is the case with this study, it is fair to call into question correlation and causation but if there were some food additive, fertilizer or herbicide that had even 1/10 of the correlative impact on children, the public would be freaking out and protesting around some multinational business but when it is parents damaging their own children we get relative silence.

Studies have shown that poor parents are more likely to spank their children. Studies have shown a correlation in spanking with smaller brain sizes, lower IQs, lack of self control. Studies have shown a high correlation between lack of self control and poverty. Again we don't have great data on cause v.s. effect but there are good indications that the early violence is causative in this chain.

1) if you make exploitation less likely than an astroid hitting the earth, then for all practical purposes you can say that it is prevented.
2) 'repeatable crash bug behavior' doesn't matter, it will be repeatable if it is run in valgrind/address sanitizer or via a debugger which is really all that matters to a developer. An end user couldn't care less about repeatable crashes and would prefer if it occasionally/usually continued running.

I have no idea why you would believe that "our genetic code is a type of program", I don't think anyone working in molecular biology has this interpretation. And even if you view the genetic code as a type of program, then it is a program that primarily deals with how the individual cells that make up our body operates and _not_ how the brain processes input.

Do you really think MSS has not been developed since the 90s? Admittedly I haven't used it since 2004, but back then it was pretty much the only way to get good, performant 3D audio running with a variety of sound cards. I'd imagine it has grown a whole lot of features and platform support since then.

It's generally desirable to have the AI and physics run at a fixed time step because it allows you to reproduce results exactly. That way you can record gameplay by just recording the inputs. So usually you will have a 'simulation' thread running at a fixed tick rate and a 'render' thread producing frames as fast as possible. I agree about the Vsync, there is not point whatsoever in making frames faster than the display can display them.

And in fact that's the problem with this frame-time benchmarking, if the workload is such that it's artificially rendering more frames than can displayed it doesn't really matter much if they are displayed at a consistent rate. If you want to see how much better a multi-GPU solution is, you need to test a workload that is being rendered at less than the Vsync rate (or at least around that rate).

Talent does what it can. Genius does what it must. You do what you get paid to do.
