I use a password manager for the bad practice of high password complexity. Passwords like 'mj%9F!17' that should have never been created because they're crap, and impossible to remember.

For my important stuff--like my password safe password--I use passwords like "crazy_dutch_flying_candybar". It really doesn't make a difference if you use underscores, spaces, or concatenation; just use the same always so you never have to remember how you formatted it. Most systems accept underscores, and concatenation is confounding due to the mental impulse to add a space.

You can also make up numerics and memorize them with Dominic's System, but this greatly reduces entropy. For example, if you used 1477 and came up with "jesus_christ_chasing_girls" (because 14--AD, Anno Domino, The Year of our Lord, Jesus Christ--and 77--GG, Girls Girls, Yakko Warner, chasing girls all the damn time), anyone who has your Dominic's matrix can come up with a few thousand likely passwords. Even with some interpretation, there are 100 names and 100 activities describable in a handful of sensible ways, so maybe 100 x 500, give or take.

I really hate solar panels.

Concentrated sunlight into thermal generators is more efficient, cheaper to produce, cheaper to maintain, less toxic to produce, and so on. Europe? Parabolic reflectors focus light from an infinite-distance focal point to a fixed focal point, where you place a sterling engine or a salt tower.

For the home, you don't want all that conversion waste. Electricity is the last thing you want. You should have a solar hot water system with an evacuated tube collector--a set of 18 180mm tubes costs $450, and can keep a 150L hot water tank at 190F in the summer (92F outside temperature design spec, Baltimore) or 140F in the winter (Baltimore design spec of 14F or -10C). They're not that big: 2.75m^2 panel at 37-45 degree mounting taking up 1.75 square meters of roof space. You can shove multiple up there to far exceed your hot water needs.

With the solar water heat, you can pipe directly to your hot water tank with a set temperature of 160F. Use a thermostatic mixing valve so that hot water draws hot mixed with cold, providing 130F water or cooler. The hot solar loop will bypass when the tank's 160F, by use of a thermostatic bypass valve.

In the winter, a hydronic heating coil will circulate your hot water (down to 130F) through a hydronic heating coil in your air handler. In the summer, the solar heating loop passes through an absorption cooler, providing air cooling. Thus your direct solar heat powers your heating and your air conditioning, both. AC can use an electric or gas back-up; water heat back-up is also your central forced air heating back-up.

When both the hot water tank and AC are bypassed, the solar hot water loop is pumped through a reverse-flow cooler. This cooler exchanges its temperature (at above 80% efficiency) with the hot water loop temperature: if your solar loop is coming down at 190F, and your cooling loop is 150F, then your solar loop will become 150F and the cooling loop will become 190F. Some mixing can control the cooling loop to keep it hot (i.e. pump part of the hot water loop through it, so that the hot water loop maintains or continues to raise temperature). This prevents the solar loop from overheating without shutting it down (normal practice is to stop the pump and let the tubes get ridiculously hot; with normal polyethylglycol coolant, this becomes acidic).

The hot cooling loop powers the hot side of a Sterling engine, which is cooled by vent fan or ground cooling (in a basement, use the sump!). The sterling engine, of course, generates electricity!

So, in short: evacuated tubes on your roof heat your hot water, your space heating, and your cooling, directly, all by the use of a single plumbing line down to your basement or furnace room. A sterling engine (likely 20%-30% efficient, unlike 8% thermocouple--but watch for newer quantum tunneling junctions configured as thermocouples, in 12-15 years) converts any remaining solar energy into electricity.

Glass tubes. Plumbing. Thermostatic valves. Ethanol and water. Four small pumps--main loop, hydronic, sterling hot, sterling cool.

Um, no. Congress may have written a law covering some things under the Commerce Clause; the Department of Commerce is a federal agency and, like the FDA and DEA, it was created by executive order to execute the power of legislation passed by Congress.

Congress created laws allowing for the regulation of controlled substances (drugs) and the quality of food and such substances, devices, and procedures as were useful for medical purposes. The latter became the Food and Drug Administration, and the former became the Drug Enforcement Administration. These were created by Executive Order to carry out the legislated regulatory powers which Congress passed into law.

The Department of Commerce may or may not have Congressionally limited power. I could see them pulling the Incorporation trick, passing a law that says the Federal government shall pass and enforce regulations as granted by powers under the Commerce Clause; but that would include a whole bunch of shit that Congress has had to pass laws for recently, and would overlap with the FCC and the FDA and hundreds of other Federal agencies. We have over 1800 Federal agencies here.

He needs majority in Congress to pass legislation. Also, the President has no power; he has influence, and is basically a figurehead who gets to tell Congress what to do because Congress gets to blame the President when they fuck shit up.

Think about all the stuff Bush did. Now realize: Bush blew up some shit in Iraq and Afghanistan; everything else that happened during that 8 years--tax cuts and other fiscal policy, any military spending over $56Bn, stem cell legislation, etc.--was all Congress. Now consider Obama, the ACA, tax structures he put in place, and so on. None of that was actually Obama.

We get to blame the President, and no one blames Congress.

Because customers don't immediately respond to questions like "why should we discontinue your service?" with responses such as "because I have informed my credit card provider that we are no longer doing business together, and they will refuse all further charges and will charge back any they don't refuse, at cost of $35 per false charge to Xfinity Inc."

Exactly. Congress has to write a law saying, "By Constitutional law, we are tasked to facilitate interstate commerce. This is impeding interstate commerce; therefor, the new law says: stop doing that." Then the President can point and say, "Go Go Federal Agents!" and any lawsuits raised by Tesla can get to the Federal Courts where the Judge is obligated to say, "Your state laws are in conflict with Federal regulations which are supported by powers Constitutionally granted to the Federal government, therefor the Federal regulations trump your State laws."
