Comment Re:Cores Schmores (Score 2) 118

I think the solution for the new PC is going to be a combination of both. 4 fast as possible cores; maybe 8. Then massive additional cores at lower clock speeds and simpler design. Most likely implies a hybrid NUMA design with additional performance specs and turntables for the host OS and user level software(games). Probably a few modes of operating. Automatic management and succeeding levels of the OS taking over management.

Think of the slower processors as something akin to a floating point coprocessor. Programmers are lazy. Until the hardware exists and they know they will see a benefit they don't want to program for it. Programming for massive unknown hyperthreading is a hard topic. They will always choose the lowest common denominator.

But having both fast/few and slow/many/efficient changes the game. The fast/few is at the end of it's performance curve life but will live on. It's nice to have a few cores around that run two to three times faster for difficult programs. But having an undetermined number of extra processors sitting around.... programmers won't be able to control themselves when they want more performance.

I can also imagine this extending to mixed architectures such as x86+Arm like we have heard rumors about. CISC+RISC in the same computer; blasphemy. FPGA compute boards and graphics card becoming coprocessors and integrating on a more equal level with the CPU's.

P.S. The future of operating systems is a three tiered approach: Hypervisor->OS->Programs. The hypervisor being something akin to a microkernel. What if instead of building compatibility into successive operating systems you could run them all together and forget about compatibility altogether. With additional software and drivers I can even see compositing. This means we can run FreeBSD, Redhat Linux, Ubuntu, Gentoo, Arch, DOS, Windows 3.1, Windows XP, Windows 7, Windows 8, Windows 10, and GNU Hurd, and multiple x86 and Arm versions of Android all on the same machine. Imagine all those with compositing extensions.... And once you get rid of the browser with Flash and Shockwave 99% of viruses disappear so administration actually gets easier and if you do get a virus you can always rollback; or rollout clones to test software. Also one can setup a file system with features like file versioning and encryption so that programs can't just hijack your data.

The reason I brought up the above is because one can further still extend the hardware with a clustering OS. A business could install such a specialized clustering OS on each of it's desktop machines in the building and then have it's own cloud. Imagine using something like that for rendering and processing video.

Comment Electricity Superhighway (Score 1) 346

This is what I have been saying for years. Although I have usually stipulated they should be using superconducting highways; I see that's not necessary to get the ball rolling on a national infrastructure. I think it should be a government run operation with subcontractors building it out. It should be government run because I feel it's a matter of national security. Should a natural disaster strike the government should have a locked in system for rerouting massive amounts of power around damaged areas. But one of the problems with the current grid is that when power is generated from renewable resources it's in areas away from where the majority of the consumers are.

Comment Don't see the big deal (Score 1) 183

I don't see the big deal. The only thing they really control is registered blocks of IP addresses. As far as domain names... it's since different DNS services can compete side by side; anyone can come up with an alternative system.

One can easily alias domain names from one system into their own top level domain like:

Furthermore programs could then have search paths for multiple domain system. The system is easily extended. An improvement on this would be if web sites that instead did something like a cname to a GUID and then the GUID/PubKey and that is what is then resolved to an IP address.

What I would like to see is them forcing the issue of IPv6. Such as in order to renew your IPv4 block you must insure that a certain percentage of your network is IPv6 with this number growing year after year. Also they could reduce the blocks of already assigned IPv4 addresses. It's not like people/businesses don't have alternative in IPv6.

Comment Maybe 25% nuclear (Score 1) 645

But capable of %80. It's going to take a combination of everything. Run nuclear the backbone but use up renewable where and when you can get it.

And I'll gladly live next to a reactor if I get a little something out of it... like free power for life. You could build it in the desert and I'd move right next to it and just crank up the AC.

But really we need to focus more on small thorium reactors with enough classic reactors to breed the thorium. And truly our country needs to get off it's ass and start recycling nuclear waste.

They are creating a patent portfolio so they can counter-sue other companies that may sue them. Doesn't matter if the patents are bogus.. it takes time and lawyers fees to go through the federal courts. And the patent system isn't broken?

We need a patent system with more critical examiners. But the examiners are understaffed and only seem to rubber stamp patents anyway so lets create a separate court system for just patents; with an overstaffed public defenders office whose job it is to strike down patents. All patent must go before a judge before they are officially approved. Furthermore anyone in the public can sue to challenge the patent to augment the public defenders. And the judge must have the special responsibility to not approve a patent if he has any doubt. Meaning it's up to whomever submitted the patent to prove their case and that all issues have been brought up. Make it mandatory that the patent has to serve the public's interest; and in conjunction with that judgement make the term length of the patent variable. Furthermore the court should have the ability to set the valuation of a patent and to forcibly grant licenses to others.

Comment Notification pages need improvment and new laws (Score 1) 115

The notifications pages that come up need improvement to let people know what happened. Just because a certificate doesn't pass doesn't mean

Second there needs to be laws on the books that manufactures must abide by to sell embedded products.

1. They must offer security updates for all embedded devices for 25 years.

2. They can EOL their product anytime prior by opening the devices to external developers and firmware.

3. Going bankrupt does not negate these responsibilities so each product must have an immediate action plan to comply with #2.

4. Every company must be audited yearly for #3.

Comment You go dude (Score 2, Insightful) 578

Immigration is an important economic issue. It's lowers wages. It's a way to balance economic forces but if unchecked it gives businesses an unfair pool of low wages employees. If you don't respect parts of your country for it's economic impact on your then I don't see anything wrong with what your doing as a "statement of protest". You have the unalienable right to express your dissatisfaction. But being realistic it just won't have an economic impact.

Comment We are so in our infancy (Score 1) 37

The brain is the communication hub for the body. It's has a spinal column that spans neurons across the body. Nerves whose purpose is input and output to the brain.... And we are playing with switching them on and off with light and sound.... We haven't even figures out how nerves address the brain and each other. We don't even know how to coax the brain into making new connections. So primitive.

The market is more than large enough that Tesla can't keep up with demand. Porsche adds luxuries on top of the electric car. What if you don't like the look of the Tesla or you want other colors/features. These are two kids playing in a sandbox the size of a small city. More than enough room for both of them. I even find it likely that Tesla may consult for them and eventually in 5 years be selling them batteries from their Giga factories.
