I agree. If you don't mind tinkering, pfSense is the way to go

I agree that pfSense is a great solution but I disagree about the tinkering . pfSense fits well in the mantra of "simple things can be done simply but complex things are possible". It needs little tinkering if you have a reasonably standard setup - say an internet connection plus a local network. It has decent defaults.

If you have a more complex setup (I have a LAN interface, a DMZ, a guest network, and a VPN interface as well as several additional software packages) then some tinkering will be needed.

I have pfSense running on a Soekris net6501 for my home network firewall. I have set up OpenVPN - configuration took only a few minutes and it has worked perfectly.

The Soekris Net6501 is more than sufficient for my needs but pfSense scales well and will run on many types of hardware. When I was testing it I ran pfSense as a VM without any problems - in retrospect I should have left it that way permanently.

This isn't patent trolling. nVidia literally invented the GPU and much shader technology back in the 1990s. A lot of graphic stuff now considered basic was developed and patented by nVidia.

These are probably legitimate patents that other companies are using without a license. One of the reasons that Intel graphics technology is still far behind is that they are coming late to the graphics game and have a patent minefield to avoid. It looks like Qualcomm and Samsung decided to ignore the minefield and hope that they didn't step on a patent mine - or at least not step on one that would be noticed by nVidia.

NVIDIA is seeking damages and a ban on US import of a raft of devices with Snapdragon and Exynos processors until there is an agreement on licensing."

They offer potentially even greater potential for security-sensitve clouds in the future. The ideal solution is to provide the benefits of containers, while actually reducing the attack surface. In the age of the cloud, systems need a higher degree of security than ever before."

1. Place immature people (of any physical age) in an anonymous, no consequences environment.
2. Give them the ability to address people whom they would never have the opportunity to approach outside of a virtual environment.
3. Supply a conduit such as Twitter or Facebook or email that requires very little effort compared to writing and mailing a physical letter.

The result is completely predictable.

Automobile companies make a large number of vehicles - both GM and Toyota make around 10 million per year. Saving just one dollar on each vehicle adds millions to the company profits.

Something as simple as the extra wiring to create multiple data busses in the vehicle could add a couple of dollars to the vehicle cost. The auto makers will not do it unless it is mandated (either by law or their legal department fearing lawsuits) or they see some sort of a competitive advantage (somewhat unlikely) or there's a PR disaster.

nVidia makes the chips and very recently a couple of reference designs and retail tablets. They don't make the OS and other software.

As you pointed out, Google (not nVidia) removed support for CL rendering to push their own product. I'm sure nVidia was unhappy about that as it removed one of their competitive advantages.

With the Tegra K1, nVidia is pointing out (quite rightly) that their hardware supports a bunch of new things. nVidia's literature describes the Jetson-TK1 as a development kit, not a product. It is made available so that people can write software that supports the features in the hardware

I completely fail to see where nVidia has been dishonest in this.

Neat test. I worked hard on it but only managed a Total Error Score of 236.

I already knew I was color vision challenged. My mother became suspicious when I was playing with crayons and I colored a fire engine green and the grass brown. That's why my wife picks the colors for my clothes and sorts my socks so I don't accidentally wear a non-matching pair - which has happened a few times.

There is nothing to stop my neighbors from doing installing solar also - and several have.

Do householders thank their neighbors for the break they get on their mortgage interest that allows them to afford their houses?
Do the various fossil fuel industries thank every tax payer for the huge subsidies that they receive?
Do farmers thank everyone for their subsidies that permits them to grow crops like tobacco that kill tax payers?

Governments have always promoted certain types of behavior with subsidies and tax breaks. There's nothing wrong in going along with their wishes if it benefits you also.

Out of curiosity, what was the pre-subsidy and tax incentive cost, or alternatively what were those subsidies/taxes?

The installation is rated at 8.9 kW DC (7.5 kW AC) and the total cost was $65,000. I received a check from the state of California for $29,000 and a tax credit of $5,000. So my out-of-pocket cost was $31,000 . All numbers rounded and in 2003 dollars.

Will home insurance cover these panels in the event of hail and wind damage?

I don't know. I didn't think to ask as I haven't ever seen a hail storm here and we don't get very high winds. However, chemically strengthened glass is used for the panels so they are less likely to be damaged compared to float glass. The panels are solidly anchored to the rafters and the roof is metal tiles so they aren't likely to blow away.

I did check that everything is covered for theft or fire damage as the inverters were quite expensive back then.

Solar energy provides all the electricity for my house, and has done so since 2003. Not a single electricity bill since that time.

I installed 48 panels on my roof and I run the air conditioning, washing machine, electric dryer, dishwasher, and everything else electric from the roof panels. We do have gas heating and a gas range. I have a modern thermostat and I set the low point to 72 degrees and the high point to 76 degrees and let the system figure out how to keep the house in that range. I leave it set that way all through the year.

In the the year before installing the panels I spent $2800 on electricity, and prices have gone up considerably since then. The costs of the installation (after California state subsidy and tax incentives) was $31,000 so I've fully recovered the installations costs. I expect the panels to continue producing all the electricity I need for the next 20 to 30 years.
