Ask Slashdot: Best Dedicated Low Power Embedded Dev System Choice?

jkflying Re:Solaris not well supported by OSS toolchain (183 comments)

An MSP430 has idle currents measured in uA, and a chip costs in the region of $1.50, with no external components required. BBB isn't useful in applications that require running off of a watch battery for a year, and isn't cheap enough to consider adding as an additional component in consumer electronics.

Ask Slashdot: Best Dedicated Low Power Embedded Dev System Choice?

jkflying Re:Solaris not well supported by OSS toolchain (183 comments)

Try developing for an MSP430 on the MSP430... hence the distinction between 'target' and 'host'. When you can develop on the target, great. But a lot of these MCUs don't have the IOPS/RAM to run a generic scripting language, never mind a compiler.

After the Sun (Microsystems) Sets, the Real Stories Come Out

Because "Segfault: 0xFCDA83B40" is *soooo* much better.

Shrinking Waves May Save Antarctic Sea Ice

jkflying Re:area is one thing, volume is another (298 comments)

Volume loss of sea ice doesn't affect sea levels, since it was displacing sea water to begin with. Volume of land ice on the other hand, even if it migrates to an equal volume of sea ice, will cause rising sea levels.

Shrinking Waves May Save Antarctic Sea Ice

jkflying Re:Negative feedback (298 comments)

Negative feedback cycles can still end up stabilizing at a different set-point, if the negative feedback is in the rate of change rather than the absolute value.

New Jersey Auto Dealers Don't Want to Face Tesla

jkflying Re:Many members of Congress own car dealerships (342 comments)

They're just larger and more expensive to process with a pick-and-place machine, so all the manufacturers go with SMD.

Ask Slashdot: How Can I Prepare For the Theft of My Android Phone?

jkflying Re:What the hell is a "punter "? (374 comments)

As somebody from South Africa (and who even takes the train through Salt River), I have to say I was also a bit confused. I'm assuming they meant a fence, although a fence isn't really "oblivious" as OP said. Perhaps they mean a customer who just happens to find a 'great deal' on a refurbished phone at their local pawn shop...

Austin Has Highest Salaries For Tech Workers, After Factoring In Cost of Living

jkflying Re:Boolean logic lessons (285 comments)

If you're male and reading /. you won't be seeking an abortion for a significant other because you're single.

Thus, since you are addressing a /. audience, your logic can be simplified to :

Texas legislature is no problem as long as you are male or not seeking an abortion.

But 2/5 for effort.

Damming News From Washington State

jkflying Re:Moisture inside the dam wall (168 comments)

The problem is that the rust is larger than the steel that produced it. This expansion can cause cracks in the concrete similar to how ice can cause cracks.

Why Does Facebook Need To Read My Text Messages?

jkflying Re:Why use their app? (293 comments)

So that Google can provide geolocation for devices without GPS by fingerprinting the signal strength patterns and access point names you see. They also use it for road traffic reports - where do you think Google Maps gets its traffic data from?

Microsoft Relaxing Xbox One Kinect Requirements, Giving GPU Power a Boost?

jkflying Re:Apples vs Apples (220 comments)

Also, a single Jaguar core only uses something like 3mm^2 of die space. That leaves lots of space for GPU.

Open Source AMD Driver Now Supports OpenGL 3.3 — and It's Getting Faster

jkflying Re:The firmware remains proprietary (100 comments)

It exponentially increases the amount of code that would have to be reviewed for proprietary secrets and patent infringement. On the other hand, just releasing the drivers wouldn't be as much of an issue, since they just target an interface that doesn't reveal what happens on the other side.

Open Source AMD Driver Now Supports OpenGL 3.3 — and It's Getting Faster

jkflying Re:The firmware remains proprietary (100 comments)

Releasing the firmware source would be pointless, since there is no available compiler which could target the hardware. They'd have to release the compiler and hardware specs as well.

Make Way For "Mutant" Crops As GM Foods Face Opposition

jkflying Re:Further proof that anti-GMO is all about the mo (194 comments)

No, from the very papers you referenced, it has been found that *a single* GMO crop didn't have higher yields than classical crops. You can't extrapolate that to others.

Your generalization is like saying the inline assembler optimizations one programmer performed didn't speed up a program, so inline assembler optimizations can't speed up programs. Which is clearly BS.

Make Way For "Mutant" Crops As GM Foods Face Opposition

jkflying Re:Further proof that anti-GMO is all about the mo (194 comments)

'Naturalness', whatever that means too. We've been doing selective breeding on all of our foods for millennia, so I don't consider organic foods to be particularly natural either. Traditional, I'll give them that, but natural? You have to be kidding me.

Or if there is more than everybody could possibly consume, and nobody needed to produce it.

AMD Confirms Kaveri APU Is a 512-GPU Core Integrated Processor

jkflying Re:Yeah i don't get it (130 comments)

Small form factor business PCs,

Don't need 3D performance. Don't need GPGPU performance in 99% of cases.

Doesn't matter, because it's cheap. Also, CAD and Photoshop *do* use GPGPU these days.

Media center PCs

Plenty fast enough already to play video at 1920x1080.

This should handle 4k video decoding.

low-end Steambox

If you want your games to look like crap.

I think you missed the "low end" part of that quote. Also, it will be really, really cheap compared to something with an additional dGPU. You don't even need PCIe on the motherboard. Not everybody can afford to game at 3x 1080p on high. These should handle 1080p on medium just fine.

Integrating the GPU into the CPU gets the BOM cost down and raises the minimum performance standard.

Because lots of people run 3D games on servers.

Certainly we do use GPUs for some floating-point intensive tasks on servers, but this is nowhere near fast enough to be useful.

These have HUMA. GPGPU-CPU interactions will be much faster than on any previous architecture because not only do they share memory space, they are also cache coherent at a hardware level. It suddenly makes having a whole bunch of FPUs on the graphics card useful for regular old FPU applications, because they can be accessed just as quickly as SSE/x87 FPUs. It makes OpenCL suddenly useful for very small kernels, instead of only being useful for massive data-processing chunks where the parallelisation had to be wide and simple enough to make up for memory copying overhead. TL;DR: I want this on my server, even if just for the stuff like generating graphics and accelerating database hashing. Never mind Folding@home and HPC kind of work.

Seriously, stop being such a downer.

There Would Be No Iranian Nuclear Talks If Not For Fracking

jkflying Re:CAFE Standards (236 comments)

To clarify, if the fuel efficiency of cars increased enough to make driving economical, they would start driving cars instead of riding bicycles.
