Comment: Mobile low-voltage chipset/CPU (Score 1) 229

by galvitron (#37348734) Attached to: Ask Slashdot: Passively Cooled Hardware For Game Emulation?
I would go with a LV (low-voltage) or ULV (ultra low-voltage) Core2 Duo mobile CPU on a Intel based Mobile chipset.

Anything more than two cores is a waste on current console emulators. There are small mobile chipset motherboards that take the Intel mobile processors from the previous architecture. They can be had for around $400 and will take 4-8 GB of ram and use a fairly modern chipset like the PM45. I think Commell still makes them with a PCIe X 16 slot. You could get a passively cooled single slot graphics card for modern emulators like Dolphin and the Model 3 emulator.

I think this MB and cards/cables, etc will fit in a very small case, probably around the size of a Mini-ITX case.

Then, get a small SSD for the OS and apps. Put the roms on a high-speed network share for lots of room for full sets (like MAME)

Then, put a good front-end like Hyperspin and you're good to go.

Some of its tasks include refueling and fixing solar panels on satellites.

And how do you know this? I imagine that it is capable of doing that, with the right payload, but from what I understand, its mission(s) are classified.

I doubt its simply up there to repair satellites...seems like an awful waste of a capable craft.

China has a fast growing nuclear submarine fleet, each armed with multiple ballistic missiles. If U.S. recon picks up a surfacing sub within 100 miles of the gun, we could get a shell there within 8 minutes...maybe fast enough to get 'em before they triple check the orders, launch codes, go through launch procedure, et al. Maybe not.

China also has a fairly large surface fleet, rivaled by only a few countries.

The race never stops, it just has clear leaders at certain points in history.

This is most likely a test. If it was a show of force, it would have been done close to North Korea or China to show the US's ability to project power. I don't think it's very intimidating for the US to show that they can launch a missile from their own territory.

So if it is a test, what were they testing? It would have to be something that mounts on a fairly small rocket. Submarine or ship based missiles are not huge like a delta.

Lately, the US has been testing the hypersonic craft such as the Darpa Falcon craft. They are usually air-launched on the back of a Minotaur rocket, but could probably be adapted for a naval missile. Part of these hypersonic tests is development of the prompt global strike capability, which is basically a program to create a non-ballistic hypersonic missile to hit anywhere in the world quickly (1-2 hours.)

It could also be a missile defense test. They often launch from Vandenburg AFB and use interceptors based in the Pacific (ship based midcourse defense) or Alaska (ground based midcourse defense.)

My guess: an HTV-2 or HTV-3 test.

I would think that the big concern with a system like this is the added weight. Is it more cost-effective to have an active cooling system such as this, but carry along the plumbing, tanks, etc.? Or is it better to simply have replaceable tiles like the shuttle, and save the weight...then have to perform all of the required maintenance to the leading edges before the next flight?

You are right in the sense of the racing being at the highest level. WRC, Le Mans, and MotoGP are some of the best racing ever. But from a purely technical level (as the topic of TFA focuses on) F1 is the highest. Look at Toyota's $200 million budget for the last years. And that is just one team...who knows what Ferrari spends.

The tech in F1 is outstanding. They are above and beyond all other forms of motor racing and car technology in general. The Le Mans Prototypes are the only thing approaching F1 levels.

There was a point a few years ago (before the new regulations went into effect) where they were worried that the intake speed of the air into the engine was approaching supersonic. Nobody really knew what that would do to the engines (read: intake manifold).

Last year, on Speed channel, Steve Matchett was interviewing a Red Bull engineer, and the engineer basically said that the real life "Q" from British Intelligence had approached them with questions about their tech. That really says something about the level that F1 plays at.

Here is an interesting fact: Despite all the limiting regulations that have been put in place, including reduced aero packages, no refueling, no traction control, etc., this weekend at Melbourne a new lap record was set by Vettel. The old lap record was set in 2004 with a V10 engine revving to probably 21,000 rpms. Current engine is a 2.4L V8 probably revving to 18,000 rpms. So, despite all the restrictions, the teams are still able to move the technology forward so drastically that they are basically nullifying the FIA's (sport governing body) efforts to slow the cars down.

As an American working with technology, I would hope that more of my peers appreciated the extreme cutting edge that F1 dances on.

You know you've landed gear-up when it takes full power to taxi.
