June 20, 2017 -- A Quick Run Around the Web


"r/K: The Evolutionary Psychology Behind Politics (by Anonymous Conservative  and read by Tara McCarthy)"--posted and illustrated by Matthew Drake (22 min.). The key points of r/K theory as applied to politics.

Firearms/Self-Defense/Prepping:
  1. Update your curtains to medium-colored drapes or curtains with white plastic backings to prevent an exchange of heat between your apartment interior and the windows.
  2. Use a "swamp cooler" (evaporative cooler). I presume this recommendation is for people without air conditioners. I would note that these work best in dryer climates, but use a lot of water. From personal experience using one for a couple summers in an apartment, the matting that soaks up the water needs to be cared for and cleaned to reduce the growth of mold or mildew. The author notes that running a fan across ice can also help cool the air.
  3. Avoid cooking with a stove top or oven, because it can heat up your apartment. The alternative is to use food that doesn't need cooking in its preparation (e.g., sandwiches), grilling outdoors, or using a slow-cooker or microwave oven for cooking (both of which will not heat up your living space like a regular oven or stove,  
  4. Wear a cooling scarf, by which the author means gel filled cloths that, when wet, absorb water and allow the water to evaporate, cooling the cloth. These are worn draped over the back of your neck. (As a side note, these can be helpful for controlling a nose bleed). 
  • "Mansfield Two Dot Pistol Iron Sights"--The Firearms Blog. This is something that you need to see to really understand, so I recommend that you go to the linked article. Basically, though, it works on the principle of Vernier acuity--"the ability to discern a disalignment among two line segments or gratings." In this case, however, what the inventor uses are two circles: half of a circle on each side of the rear sight, and the other half of each circle on the front sight. The object is to align the halves to form two whole circles.

  1. I'd say swamp coolers are less useful overall. If you don't have extremely dry air, you'll be adding humidity and raising the heat index number of the living area. Without a whole house AC, a portable AC is often a good choice. Around 12-14,000 BTU/hr, and the better ones have an inlet and exhaust hose so only outside air is used. They use the space's humidity to condense moisture out and add evaporative cooling to the coils, exhausting the humidity outdoors. I use one in my home since AC is needed only two or three weeks total each cooling season. Otherwise a whole house fan fits the needs for me.

    Spot on about the use of window dressings and coverings to reduce heat inlet, especially from the sun.

    1. Thanks for the additional information. While I've used a small swamp cooler during my college days, since then the places I've lived have all had central air, and so I have had no experience with the portable A/C units.
