Australian University Unveils New Carbon-Trapping Bricks

White Flame Re:Turning CO2 into carbonates? (142 comments)

The only reason the CO2 is sequestered is because of a particular chemical reaction, which has zero bearing on heavy metals, sulfur compounds, radioactives & other pollutants. One piece of equipment does one job, because each reaction needs its own reactants, catalysts, and general environment, and each has its cost & energy tradeoffs. One particular CO2 reaction has nothing at all to do with the other emissions.

Australian University Unveils New Carbon-Trapping Bricks

White Flame Re:Turning CO2 into carbonates? (142 comments)

Every coal- or oil-fired power plant could have it's adjacent brick factory and become carbon neutral.

Coal puts out tons of real pollution (toxins, radioactive particulates, etc), not just CO2. Sequestering the CO2 does not solve the even more immediate and tangible harmful emissions problem.

"Slingatron" To Hurl Payloads Into Orbit

White Flame Re:If it's cheaper it's still good (438 comments)

before it and the payload reenter and burn up.

If it were in danger of burning up on reentry, don't you think it's even more at risk of burning up on ascent? It's moving fastest and through thickest atmosphere at launch, instead of accelerating with further stages at altitude. And that is the entire problem behind this Wile E. Coyote idea.

Adapteva Parallella Supercomputing Boards Start Shipping

White Flame Re:Hold the bus (98 comments)

I don't know what you read, but the 6.4GB/sec chip interface bandwidth is less than a standard PCIe graphics card at 8GB/sec. Now, you may argue that there is more latency across PCIe or something, but also note that the Parallella system assumes a shared memory architecture with the host OS on the ARM.

Again, there are no dedicated RAM chips for the accelerator on this board, and the chip itself has no DRAM controllers. You can only load up to 32KB of RAM per core into the chip caches itself; it doesn't have gigabytes of fast memory available to it like GPGPU processing does. This entire architecture is based around it being very chatty across that shared memory & comm bus, FAR more than any GPU would ever be.

This chip is for inexpensive acceleration of large-ish streaming data problems, like signal processing and video codecs or maybe map/reduce work, with very little state held on the actual chip. It's hard to see it having any sort of decent performance outside that, either in embarrassingly parallel or generalized multi-core problems.

Nobelist Gary Becker Calls For an End To Software Patents

White Flame Re:how to delineate software patents? (147 comments)

They need software patents solely to give their investors feelgood vibes. Venture capitalists perceive a major benefit if a software company has a few patents covering their work. The software companies really don't care.

Adapteva Parallella Supercomputing Boards Start Shipping

White Flame Re:Hold the bus (98 comments)

You are aware that this chip has the exact same problems, right? But unlike a GPU it has very limited on-chip memory, and no directly attached external memory at all. All communication happens through a FPGA-driven channel to the ARM, with the ARM being the only thing with DRAMs attached.

This is fundamentally, and properly labeled as, an external "accelerator chip" to add onto a computer.

Supercomputer Becomes Massive Router For Global Radio Telescope

White Flame Re:Petaflops (60 comments)

Ditto. Also, in many "big data" projects, FLOPS is of little use anyway. There is a ton of textual processing and predicate matches to be done in the rest of the world. With ARM entering the HPC space, hopefully more broadly meaningful integer & IO ops numbers will be bandied about rather than just this laser-focus on vector floats.

MIT Uses Machine Learning Algorithm To Make TCP Twice As Fast

White Flame Re:All Jokes Aside... Still No. (250 comments)

It's a chaotic system. The optimal responses to that can be another chaotic system, which happens to hit the right symbiosis enough of the time to offer clear benefits. You do not need to understand how the chaos works, and even if you do, it could appear completely nonsensical.

Compared to my 1st computer's memory ...

White Flame Re:Popular Electronics Elf (587 comments)

Your current system has exactly 8,000,000,000 bytes of memory, instead of 8,589,934,592? How strange.

Microsoft Is Sitting On Six Million Unsold Surface Tablets

White Flame Re:BING = Ballmer Is Not Good. (550 comments)

Granted, they just want to copy Apple. Apple says "Look, this is new and original and you want it!" even though it's just some old rehash they decided to finally integrate, or some utterly minor tweak, and people stand overnight in lines to fork over their money.

Small Town Builds Its Own Gigabyte Network; Cost To Citizens $57/month

White Flame Re:never happen in the states (269 comments)

It's because there are multiple companies, but just 1 government. If a company does something bad, they screw up and people can go elsewhere (if there aren't monopolistic lock-ins that they try to legislate into existence). If the government does something bad, there's no other options. Consider that something will _always_ go bad somewhere, and it is better to have a more distributed set of options.

The government is also _bound_ to do things inefficiently, because they are run under rule of law and voted policy; you can't have people using their own judgment and have the liability of just "making things happen" when they represent the people, their tax dollars, and varying interests. This policy-driven model is _good_ for certain things that must be handled with legislative care, but is always going to be more expensive than what private business _could_ offer, pretty much by definition, and again a central point of failure.

ASUS PQ321Q Monitor Brings Multi-Stream Tiled Displays Forward

White Flame Exactly what IBM did, but IBM did it easy. (94 comments)

IBM's T221 monitor, the now ancient 3840x2400 22" 200dpi display, did the exact same thing.

It had 4 DVI inputs (newer models can support 2 dual-link DVIs), splitting up the screen into 1-4 stripes, depending on your bandwidth and setup. It's also directly plug & play, with no setup issues whatsoever on Linux, for what it's worth, and max frame rate is simply bound to how large each link is offering.

I've got a single card driving 2 T221s at a whopping 12Hz (single-link DVI each), and some low-res 30" 2560x1600 monitor with the displayport connector. 22 megapixels from 1 card is pretty nice, and I could be driving the T221s at 24Hz if I had the dual-link DVI connectors.

They were very flexible in their setup, not sure what Asus did here to make it a pain to set up.

Why Microsoft Shouldn't Worry About Cannibalizing Their Userbases

White Flame Re:Yeesh. How cheap do people expect things? (180 comments)

The thing is, when it comes to inexpensive devices, say under the $300 mark, that $50-100 fee is a very significant expense, as opposed to "free" Android or in-house iOS.

Scientists Use Sound Waves To Levitate, Move Objects

White Flame Re:Sound doesnt move a thing (78 comments)

Because resonances can often get you more bang for your energy buck than direct impulse.

That, and they want to move things carefully and precisely. This seems like it would be a lot more stable than using air flows.

TV Programmers Seek the Elusive Dog Market

White Flame Re:wrong (199 comments)

Point is, there is no flicker in non-CRT displays, and thus the flicker fusion frequency isn't involved at all. Having picture motion seem fluid & realistic, and color range & perception, are separate issues.

Apple Sued For Man's Porn Addiction

The fact that it was implemented poorly...

That's not the problem. The problem is the fact that humanity does not work that way in any scale beyond small clan/tribe units.
