Exactly.

File timestamps should be in linear time (GPS, TAI, whatever).

What gets displayed to you as a human is in your local time - timezone + planetary adjustment - so it matches the time on the wallclock. Do you as a human really care about the LSB in the file time? For those rare times when you do, you'll use linear time.

Looking out over the next couple of years, 802.11ac at 2.4/5 GHz would be the wireless standard that you need to install - any electronics you buy in that time are going to want that. Infrastructure needs for this are pretty well understood. After that, you'd want to be able to install 802.11ad - infrastructure to that is a bit more difficult. To support it, you'll need 1 or 2 wireless routers per room with a good viewing angle. This, to me, would say that I'd like power and wired network ports in the upper corner of every room. When I built an addition onto my house 10 years ago, the contractor thought I was crazy wanting a power outlet and network tap in the upper corner of each bedroom closet - but it's been an excellent place to locate 5 GHz routers. Adding future nanny cams, microphones for voice control of the house, etc becomes easy with such well located network access points.

Assume that the data provider entries to your house (phone company, cable company, satellite service, TV antenna) need to be provided by you. Run power to the locations, install a good ground rod at each location, run conduit from the locations to your wiring closet. If you hate everyone nailing their own ugly demarc box to your exterior wall, design an acceptable utility entrance that will hide them.

I think Cat 6 and quad-shield RG-6 to one or two wallplates in every room makes sense. For the foreseeable future, broadcast TV (either cable or satellite) is going to get distributed around your house on Coax, not Ethernet, and short of going to Fiber, Cat-6 is about as good as network wiring is going to get. It's also hard to imagine network speeds really needing to be above the 10 Gbit level that you can get with Cat-6. How many 4K video streams do you really expect to ever need on a single port? I don't know that I'd spend the extra money to run conduit to every room - perhaps only to the one or two main media centers of the house. You know that you'll kick yourself if you decide to open up a datacenter in your spare bedroom and need to install multiple single-mode fibers to the rack of raspberry-pi sized servers you install in there, but we can't have everything.

Wire all the doors and windows in the house with alarm wiring, even if you don't plan on installing a system. Make it hidden - magnetic switches embedded in the frames with magnets mortised into the door or window. Run two to every door/window, so a broken wire isn't a critical failure. If you're into christmas lights, prewire outlets under the eaves so you don't end up with extension cords all over the place. It's a good place to install a network jack also, in case you decide to install security lights/cameras.

You didn't ask about environmental design, but I agree with a lot of the posters - spend some time to minimize heating and cooling costs and maximize comfort. Recognize that most HVAC duct design is intended for minimum installed cost, not necessarily minimum 10-year operational cost or comfort. Consider humidity control - for me in Phoenix, it means humidifiers in the initial plan; for someone in Florida, it might mean dehumidifiers in the initial plan. Consider allergen control - a lot easier to implement if it's considered up front. Consider a zoned system with possibly multiple thermostats - in a big house, being able to completely turn off HVAC to unused rooms (rather than shutting the door) can have significant savings.

Consider asking the plumber and electrician to go outside their "install it as cheaply as possible" mindset, and make the systems more user-friendly. As an example, it might cost a few hundred dollars more to wire the house rationally (each circuit breaker controlling outlets in the same room) rather than lowest cost (minimize wire length, even if it means a circuit breaker controls a few outlets in three different rooms, or a single room has three different breakers so you never know which one to throw to turn off power to a specific outlet). It might cost a few hundred dollars more to plumb the house rationally - as a star, rather than point-to-point (case in point: in my master shower, the cold water comes from the water entry point a few feet away, but the hot water goes from that water entry point all the way across the house to the hot water heater, then comes all the way back (after a detour through the second bathroom) to the shower. Any disturbance in water flow anywhere in the house has a disproportionate impact on the hot water flow). Rather than a wiring closet, I'd dearly love to have a "plumbing closet" with cold and hot water manifolds that distribute water to each room (kitchen, bathroom, shower) and individual shutoffs. Ask the plumber to fully insulate all hot water pipes and add a hot water recirculation system if you're putting in central hot water (i.e. solar). Make sure the dishwasher can get immediate hot water - it really sucks if it always fills with water that has cooled in the pipes.

Unfortunately, there really isn't a DC voltage standard for lighting yet. 20 years from now, when solar electric and battery packs are standard, there will presumably be a 24V or 48V standard for house lighting that doesn't require DC->AC conversion, then AC->DC conversion inside the lighting system as we have now. You might want to consider designing in an area near your solar panels so you can intall substantial battery system 5-10 years down the road, however.

Comment: Dust and Bugs (Score 1) 253 253

        Everyone is going off on the humidity - that's the least of your problems. Assuming that it's a non-condensing atmosphere (i.e. fog), the warmth in the box will keep any additional condensation from happening and the box will run fine.

        High temperature may be an issue. I live in Phoenix, and putting a server outside is, well, not the worlds best idea. If you live somewhere where the high temps in summer are less than 90 degrees, you're probably fine from a temperature standpoint.

        Bugs and dust will be the big problems. Solve those, and you'll be good to go.

        I've built boxes before that housed computers in my garage. I made'em out of plywood, made them reasonably airtight, and put muffin fans on one end, pulling outside air through a high-quality air filter (http://www.amazon.com/20x30x1-19-5x29-5-Filter-Furnace-Filters/dp/B00GBJIENE), and put exhausts (wire-covered) on the other side. Worked fine through several summers where the garage got up into the high 90's, didn't have any problems with bugs or dust or component failures.

        The two or 4 disk NAS boxes are a great size for this kind of thing. My current home server is an ancient 4-bay Buffalo Terastation case, that I ripped the motherboard out of and replaced it with a low-power 12-volt motherboard (ASRock Q1900DC-ITX) and installed FreeNas on it. Works great, and something like that would work remarkably well for your needs.

        Good luck, and don't listen to the crybabies.

Comment: Re:Coal kills people in different ways (Score 2) 224 224

Well, a quick Google search shows you wrong - there is well-documented research into the amount of radioactivity in coal plant emissions. As an example, USGS: http://pubs.usgs.gov/fs/1997/fs163-97/FS-163-97.html
EPA: http://www.epa.gov/radiation/tenorm/coalandcoalash.html
and others.

Is it an issue? The released radioactivity from a coal plant is up to 100 times that of a nuclear power plant - but those emissions are so ludicrously low that you can treat it as (100 * 0) = 0. There really isn't a health issue from the emissions.

Mercury, Sulfur, Nitrogen, sure - Radioactivity, not so much.

You have a weird definition of "virus" and "malware".

In my world, Malware includes everything that gets installed on your machine (surreptitiously or not) that does "bad" things ("mal" = (french) bad, evil). That would include worms, viruses, rootkits, unwanted toolbars, home page redirectors, Stuxnet, Cryptolocker, and just about every other form of third-party computer abuse.

Some people use shortcut keys to launch applications. Some don't.
Some people put icons on the desktop. Some don't.
Some use the menu. Some don't.
Some use the task bar. Some don't.

I don't use shortcut keys.
I put icons on the desktop for apps I use once a week.
I use the start menu for apps I run seldom (like IE).
I pin daily apps to the task bar.

I guess the only point is that people aren't binary - with multiple ways of doing things, different people have different weights that they apply to each method to help them do things the way they work. Many of them don't use exclusively a single approach.

One of the big failings of Windows 8 was ignoring this, and forcing a single, completely different way of working on people.

LMFAO. You're exactly correct.

Comment: Re:Probably the home router... (Score 1) 574 574

No, what I'm describing there is a standard consumer router that implements NAT. The Address Translation step itself is what blocks access to the ports on my machine, not any kind of stateful firewall, so yes the address translation step helps me. It may look something like a stateful firewall, but that's not it's design goal nor it's intended function, so I certainly wouldn't rely on it to be a good one.

Comment: Re:Probably the home router... (Score 1) 574 574

Please stop arguing that NAT gives you a security advantage. NAT in and of itself does not provide any additional security.

Sure it does. Does it provide perfect security? Nope. Are there better security solutions? Yup. Is it better than not using NAT? For most people, yup.

Example: I run a Windows box behind a Cable Modem and NAT router at home. Being a Windows user, I have no idea what ports are open for connections on my machine, and I don't care. You simply can't attack port 21, or 23, or 25, or 137, or 445, or whatever, on my Windows box unless I set up a mapping on my NAT router (which, being a Windows user, I don't know how to do). Any susceptibilities resulting from having those ports open simply aren't accessible to the broader internet.

So, yes, security is better with NAT than without. But, no, it won't prevent users from connecting to services you don't want it to. Neither, in general, will your solution, given a sufficiently determined user. So does that mean that your solution has no security?

Comment: Re:It's incredibly frustrating... (Score 1) 535 535

In many cities in the US in the '70s and '80s, cable companies were given a state- or municipal- granted monopoly on cable TV for 20 or more years to guarantee a return on the 10's of millions of dollars it cost to wire up the city. This was seen as a GOOD THING as everyone could then get soft-core porn from HBO that they couldn't get from OTA broadcasts. Legally, no other cable provider was allowed to install infrastructure. Prior to that, the Phone Company (there was only one at that time) had a legal monopoly on installing and operating phone lines within most cities.
Fast forward to today, and you find that there are only two possible providers of Internet service within a city - either the Cable company, whose infrastructure was installed when they had Monopoly status, or the Phone company, whose infrastructure was installed when they had Monopoly status. There is little financial incentive for a third party to spend 100's of millions of dollars to install new infrastructure, when the incumbents have proven themselves perfectly capable of dropping prices through the floor to guarantee failure of the upstart, then raising prices back up again.
In my town, during a building boom a few years back, it was common for developers to auction off the rights to wire up the neighborhood they were building to either the cable company OR the phone company - one of them paid to become a de-facto monopoly in the 100 unit community. Not a government monopoly, but one that's just as disturbing.
