You aren't insulting the SCA, you are flattering it. Treating SCA events as role playing, what I think of as a joint fantasy, is unfortunately far from the norm.

Taking a shower this morning I was struck, not for the first time, by how badly designed the mechanism for controlling the temperature is. Turn it a little to the right and the shower is uncomfortably hot. Turn it just a little back to the left and it is uncomfortably cold.

+Clayton Neff, I think all the major brands have thermostatic valves now, but those two companies have been at it the longest. Personally, I've used a number of Hansgrohe valves (both in the higher-end lines and in the more consumer-oriented, lower cost, lines). Some don't have two separate knobs (one for temperature and one for volume) per se, but rather have a single control with different motions for temperature than for volume, but even those will let you set the temperature once and just use the volume-controlling motion forevermore without messing up your temperature setting. All the Hansgrohe products I've used have worked very well.

In the higher-end systems, the plumbing is a little different than traditional hookups, or at least you think of it differently. The hot and cold supply pipes go to the thermostatic mixer valve, which outputs the mixed water full-blast. You run pipes for that full-blast mixture to a number of volume control valves, one for each feature. That lets you control the flow through each feature separately (like a shower head, a rain head in the ceiling, body sprays in the walls, a hand-held spray, or whatever).

The traditional way has the hot and cold going to a combination control (both volume and temperature) and a "diverter" that sends the water either to the tub or to the shower. You can't control the flow volume separately, you just "divert" (route) the flow to whatever output you want on.

It does not demonstrate the greenhouse effect. Assuming the experiment is done correctly it shows that CO2 absorbs more of the light than air does. But the greenhouse effect depends on selective absorption--absorbing more of the long wave length light coming up from the Earth than the short wave length coming down from the sun. This experiments gives us no information about that.

If the CO2 absorbed all frequencies equally, the effect of absorbing incoming light and reradiating some of it up would balance the effect of absorbing upward light and reradiating some of it down.

+Nathan Scott It is the thermal IR being radiated off the surface of the water in the bottles that is being absorbed by the extra CO2, not the incoming light from the lamp. The lamp is to heat the water, not the air.

+Jessa Mittleman "...their goal of exacerbating a tribal split between Western and Muslim societies?" Is that their goal? I thought their goal was to kill or enslave all infidels.

I've used turkey bacon for those kosher event attendees. Tastes fine, have had no complains. People love it. Though it is better with real bacon.

I have the exact same problem - I just moved around 1'000 books to my new home in Geneva, a hellish effort, given their weight and volume and I have no idea why, because I have over 6'000 books in PDF format, so I barely open those books, except for a few children's stories.

But the idea of trashing books creeps me out. It's like murdering good old friends... :/

I have successfully avoid MSW for decades now (except to open email attachments). Though it became difficult when MS bribed Corel to take WordPerfect Mac off the market, and OS X stopped supporting OS 9. Initially I made do with Mariner Write for little things and Mellel for big things; I currently use Apple Pages 4.3 (I can't use the more recent versions). Nothing is ideal.

Evidence of how Stupid Partisanship Can Make You

After listening to the video and failing to persuade him that host said nothing of the sort, that the post and his response were evidence not of her stupidity but of how eager partisans are to think badly of members of the enemy tribe, I made a transcript of the relevant part of the conversation ...

This experiment does not demonstrate the greenhouse effect. That effect depends on selective absorption, on CO2 being more transparent to the short wave length light coming down from the sun than to the long wave length light coming up from the Earth. The experiment shows that CO2 absorbs light from the heat lamp but doesn't tell us whether it would absorb any less if illuminated by sunlight instead. The claim that it does demonstrate it is evidence that neither the young man doing the experiment nor the people posting the video understand the relevant science.
