At our house, electricity usage goes UP in the winter -- We heat with a geothermal heat pump with resistance heat as the back-up for very cold days.

I had a heat pump once...was a bit of a shock to find my electric bills in the winter were about the same as in the summer, having moved from a condo with gas heat where the combined bills were lower in the winter than in the summer. I'll never have electric heat (whether heat pump or otherwise) again if I can avoid it. The difference in cost between it and gas heat is ridiculous.

Even if Iran had ICBMs and nukes on a scale of the US or Russia they would not attack anyone with them. That is the whole concept of M.A.D. If Iran nuked Israel the nukes from the US, UK, France and the distributed nukes of Israel would completely destroy Iran within days.

MAD only works when dealing with rational actors. The Russians were rational enough. Iran? Not so much.

I'm a Java developer. I have a decade of experience doing that. Why are all these companies hiring .Net developers not even giving me a chance at an interview? It's all computer programming. They're discriminating against me!

That's more a function of IT outsourcing hiring to HR. HR asked for requirements. IT replied with what it's currently using. HR doesn't have the domain-specific knowledge that would indicate that most anyone worth a damn can pick up a new language fairly easily, so if your resume says C++ when they're looking for C#, it gets circular-filed by HR.

(I got lucky with my current job...was referred to the director of IT by one of his acquaintances, so HR only got involved after the decision had already been made to hire me. I went from doing streaming video/audio with C++, DirectX, and our own compression algorithms to doing business-specific web apps with C#, ASP.NET, and SQL Server...rather a different skill set, but that's the kind of adaptability that the HR droids never take into account.)

I spent days getting the wrong results until I realised the problem was pi. i had been using pi=3.1415926535

Why are you trying to represent an irrational number with a rational number of unnecessarily limited precision? If pi isn't defined as a constant in whatever language you're using, calculate it yourself and store it in a variable for future reference. 4*atan(1) is fairly common and simple for this purpose, and you'll get as many digits as the underlying datatype will support.

Cite some sources? Because my state sure does not exclude basic groceries. When I look at my grocery receipt, it clearly states the tax percentage and is applied after everything is totaled up. If there is a state that does not follow this method, let me know.

Wherever you are (you don't say), I suspect your sales tax on groceries is more the exception than the rule. For just one example, Nevada doesn't tax groceries. If you're paying tax on a grocery-store purchase, it's for (1) non-food items (such as cleaning supplies) and/or (2) prepared, ready-to-eat foods (such as fried or roast chicken from the deli counter, vs. a box of frozen breaded chicken strips or a package of fresh chicken that needs to be cooked first and isn't taxed).

It's kinda like "global warming," where any change in the weather (or any lack of change in the weather) is cited as proof. A Venn diagram of SJWs vs. warmistas would, I suspect, have a very high degree of overlap.

I think BBC may take the opportunity to just clean house and bring in a new set of 3 hosts. The chemistry that those 3 had was great, so just lugging in a new replacement with the 2 remaining would be a disaster. But it could work with a set of 3 completely new hosts.

Not likely. Consider The Man Show as precedent; it pretty much jumped the shark when they tried to replace Adam Carolla & Jimmy Kimmel.

Besides which, an incandescent needs a bulb that can handle a hard vacuum, a machine to make a hard vacuum, and an entirely separate manufacturing line to all your other electrical bits and pieces.

Lightbulbs haven't used vacuum for decades. They're typically filled with an inert-gas mix (predominantly nitrogen or argon, possibly with small amounts of other gases) at atmospheric pressure. Not only does this allow use of a thinner, lighter envelope, it also makes the filament last longer.

Yeah, professional flash... professionals have those on their professional cameras. I've never had one.

If you've ever had an SLR (hardly the exclusive domain of professionals, though it does imply a familiarity with photography beyond snapshot-taking), you probably have a flash for it kicking around. I dug up my old camera bag the other day to test a K-mount to EF-mount adapter so that I might use my old lenses with my new camera. My old flash, a Sunpak Auto 222, still works. I've had it since I was 13 (just realized that makes it (and most of the other stuff in the bag) 30 years old). The new camera has a pop-up flash, but this one is probably a fair bit more powerful. It's definitely aimable from straight ahead to straight up, which is something you can't do with the pop-up flash. Put the camera in manual-exposure mode and the flash works the same with the EOS Rebel T5 as it did with the K1000.

Is this stuff common? Probably not. In the domain of professional photographers, though? Definitely not.

I calculated this at 8 MH/s out of my memory and missed a comma but if it's 14MH/s that's only $3,534.62 per day. It's something like a 100:1 loss on electricity at $0.11/KWH by the way. Hurray for efficiency.

Of course, when it's your vict^H^H^H^Husers paying for the electricity and not you, you really don't need to care what it costs.
