Water filters, acts of defiance, and thanks

Life keeps getting in the way of that blogosaurus I’ve been attempting to work on.

In the meantime here are a couple really good items courtesy of other sources.

First, Widener’s has an excellent, review of water filters for backpacking and survival. The early part of the article goes into deep, deep detail about how filters work and what they filter. Then it rates (from “pure” to “murky”) the advertising claims of 17 brands and models of portable filters — finding that many don’t remotely live up to their hype. They offer enough lab-test detail to give a good idea of how each filter really works against bacteria, cysts, and viruses.

A long read, but very good work from Wideners.

Then, via Wendy McElroy, here’s an act of outstanding courage and defiance by teenage students from Hong Kong. As the Chinese national anthem is played at a school assembly, they override it with another song, the anthem of the current resistance to Chinese government tyranny:

The audio and their rendition aren’t the greatest, but you might recognize the song from this, the greatest moment in Les Miserables:

Finally, I came to the library today to catch up on emails, including sending thanks to the latest readers who “bought me a coffee” or signed up to be Patreons. Unfortunately, one of the library’s resident crazy people is here today and he’s a very friendly, thunderingly loud character. My concentration is shot. Now one of the other regulars, who mutters to herself and sometimes weeps or whimpers as she hammers on a keyboard just arrived and seems to be having one of her bad days.

So I’m going to get out of here now and try to catch up later. For now, just a quick, but hearty thank you to: PM, who has bought me two coffees and signed on as a monthly patron; newest patron RB; returning patron JW; coffee buyers and near neighbors J&L; and donor JB.
