If the name of the game is modularity, the AR-15 certainly stands on the podium of best examples. The split receiver makes swapping calibers as easy as pulling two pins and replacing the AR 15 upper, with each one retaining its own zero, so long as you don’t remove the optic. Budget, custom performance, and the fun of it drive… moreRecoil

Here’s what its creator terms "A Hastily Created Documentary on the A-10 Warthog".  I had to laugh.  It’s only about 3 minutes long, but it’s fun.

A few grunts of my acquaintance, who relied on the Warthog to pull their butts out of trouble in the sandbox over several tours, also laughed as they watched it.  I daresay even the A-10’s pilots will enjoy it.

sciencehabit shares a report from Science.org: It takes a lot of science to stop a fire. To prevent homes and workplaces from going up in smoke, manufacturers have added flame retardants to plastic, wood, and steel building materials for decades. But such additives can be toxic, expensive, and sometimes ineffective. Now, researchers in Australia and China have come up with a new flame retardant that, when exposed to extreme heat, forms a ceramic layer akin to hardened lava, squelching the flames before they spread. "This is very good work," says David Schiraldi, a chemist at Case Western Reserve University, who has developed other flame retardants. He notes that the ceramic’s starting materials aren’t particularly expensive or toxic, making it more likely to see widespread use. "[This] could impact public safety in the long run."
[The researchers] used three components. First, they created a mixture of several metal oxide powders — including oxides of aluminum, silicon, calcium, and sodium. That mix begins to melt at about 350C (below the temperature of most flames), forming a glasslike sheet. Next, the researchers added tiny flakes of boron nitride, which flow easily and help fill any spaces between the metal oxides as the glass forms. Finally, they added a fire-retardant polymer, which they described in ACS Nano in 2021. The polymer acts as a binder to glue the rest of the mixture to whatever it’s coating. That mix dissolved in water into a milky-white solution, which they then sprayed on a variety of surfaces, including rigid foam insulation, wood, and steel. After it dried, they blasted each coated material for 30 seconds with an 1100C butane torch. In each case, the coating melted into a viscous liquid, covering the material in a continuous glassy sheet.
When heated by the torch, coating spewed out nonflammable gases, such as carbon dioxide. As it did, it became more dense and formed a uniform, noncombustible char layer, which blocked flames from spreading to the materials underneath. The novel flame retardant protected rigid polymer foam — the kind used to insulate homes — better than more than a dozen commonly used retardants, the researchers report today in Matter. The new coating also excelled at protecting wood and steel. If sprayed on building materials during construction, the new coating could prevent disasters like the 2017 Grenfell Tower fire in London, where 72 people died, the researchers say.

Someone in Palm Beach tells New Yorkers leave if ‘woke’

Someone had a warning for New Yorkers visiting former President Donald Trump’s new hometown — leave if you are “woke.”

Palm Beach police are investigating after someone placed fliers over the weekend on New York-licensed cars parked in the wealthy island reading, “If you are one of the those ‘woke’ people — leave Florida. You will be happier elsewhere, as will we.”

Remember that I just recently wrote a post about some fucking guy who had the Progressive audacity to leave San Francisco,  because it is a failed city, for Miami but say that Miami is worse.

This is what Red Southern states have to deal with.

I’m learning all about what New Yorkers are doing to North Carolina.

Telling those fuckers to stay out with flyers is probably the nicest way Southerners have dealt with carpetbaggers.
