This is interesting to me.....even if they didn't request the IP, in DOD contracts, if you spent money on it, it at least becomes FOUO. Meaning that you can't really license it. I had thought that it would be government wide -- that if government money is spent on it, even if some was chipped in from the other entities, that it becomes if not fully owned government IP, at least free for government use.....maybe the DOD had just learned their lessons earlier...

For some reason Bennett thinks that the free market works nearly instantaneously, and everyone gets perfect information instantly and instantly makes the switch. The real world takes a bit longer than that for information and action to spread. It often takes multiple years before a market shakes out problems like this. This is Econ 101 stuff -- stop puzzling and read some case studies.

They have the drawings, but that doesn't mean that they have all of the processes -- these are complex items operating at the edges of materials science. The Russians are still more advanced than the US in many metallurgical sciences. There are some alloys and specific metal grain configurations used in the RD-180 that simply no one else knows how to do but the Russian shops that build the RD-180 engine, which are under this embargo.

Cue the talk about when we were looking to resurrect some Saturn V engines, there were numerous compounds and other items that we didn't know how to produce either -- the proprietary process died with the one-man shop that knew the secret sauce and had the dialed in equipment.

Comment Heterogeneous Memory FTW (Score 1, Interesting) 22

I'm pretty pumped about playing with the dev kit. It has a heterogeneous memory architecture between the CPU and GPU. For lots of GPGPU applications, the latency of transfer between system RAM and the GPU can be a bottleneck. You're transferring huge chunks of data, and if you need to bounce the problem back and forth between the CPU and GPU, which is pretty common or if you have any real-time requirements, it can be a big deal. In many applications it can be 40%+ of time spent in just transferring your data back and forth from GPU to CPU.

For example, lots of people used the TK1 (predecessor to the TX1) for computer vision applications because it ran faster than the fastest GPU merely because you didn't have the memory transfer times. But the TK1 was slightly underpowered for these applications. The TX1 should close that gap, and really allow true GPU/CPU co-processing, versus shuttling around in memory.

Nvidia will be bringing heterogeneous computing to the desktop soon too -- they're already making it happen with IBM, and then their roadmap is to push it to x86 land.

Comment Re:This is why we don't trust them with anything (Score 2) 305

I fail to see how this is the case. I can't provide bagels to anyone in the US Government during my meetings because various laws do not allow it -- it would be seen as currying favor, and they must pay for it all themselves (well, you can give them up to $50 a year or something, but that's just one breakfast+lunch out of many in a 5-day meeting on the East Coast). But you can effectively donate $MILLIONS to a politician? I say that if there truly is a 1st Amendment issue at stake here, then the various government procurement officers should at least get in on the game too. Let the graft commence!

Once you start telling people how they can spend their own money, freedom is just a joke.

You cannot legally buy votes. You cannot legally pay to have someone killed. You cannot legally buy another person. Obviously freedom is just a joke and we should be allowed to do these things. Or, one could realize that freedoms among people are various balancing acts, and that striking the right balance is a good one. I don't think that you should be able to effectively buy a politician's vote. It's corrosive to our government, and our government is whom we charge with enforcing our notions of freedom. Hence, more freedom is preserved if we restrict this one; similarly with slavery, contract hit jobs, etc.

Comment I don't buy it (Score 5, Interesting) 90

I don't buy these reports at all. I just don't see it. I would imagine that Google would like to partner a bit closer with some of the chip vendors -- get some low power extensions added, more direct hardware accelerations of some of the effects that are done in Android, maybe help define some other extensions, etc. But I seriously doubt that they're looking to get into the chip design business. To do so they would have to buy a slew of chip designers, and we just haven't seen them hiring or acquiring in that arena.

Chip design is very hard and unforgiving. Google knows this, and can't be looking to jump into the business. They might want to help tailor something, but that would be about it...

Comment Re:Resistors in a cable? (Score 1) 206

Agree, which is why you're also support to support the USB Type-C negotiation protocol, which typically both ends do. There do exist some dumb chargers though, and lots of dumb implementations exist where the controller just gives whatever was asked for even if it can't supply it -- cheaper to build that way rather than spend time on pesky programming and engineering. But the big thing is that you also have to worry about the spec of the cable. Likes of USB 2.0 cables really do only support 500mA, or 1A or current. 3A would fry them, so you need something in the cable to identify that you can safely pass that much current across them. This resistor lets them know...

Comment Re:Just like HDMI cables (Score 5, Informative) 206

USB type A to type C cables require a different pull-up resistor than the Type C to type C cables. Lots of vendors didn't do their due diligence and just put the USB-C spec'd pull up resistors in their A to C cables. As a result, devices try to draw too much power.

I bought one of the bad cables, and was wondering why my wall charger was flaking out. Went online, and saw the issue -- my phone was trying to pull too much juice, overloading the charger and putting it into brownout mode. Now, this is a 4-port wall charger, so my other 3 connected devices were sitting there going charging/not charging/not charging at sub 1 second intervals for the ten minutes that it took me to figure it out. After that, my charger was acting really finicky, and I didn't trust it anymore after that current overload so I junked it. So, yea. Not overblown. Actual problem.

Comment Re:Why a experimental launch carried 13 satellites (Score 1) 60

Space has gotten cheap enough now that it's not incredibly uncommon for High Schools to build cube and micro sats as a project. Most Universities have quite a few cubesats sitting on the shelf that we built as a class project. Many of these will never see space, so if you get a chance to slap it on an experimental rocket, it's better to potentially go down in a blaze of glory than get tossed into the trash in two years to make space for the next class's cubesat build.
