Rooting applications are installed on about 0.5% of devices that allow sideloading of applications from outside of Google Play.
When an article (and a summary) include garbage like this, I refuse to take the rest seriously. Rooting is not Sideloading. There is a feature right in every stock Android system that tells Android that it is OK to accept Apps from sources other than Google. There are apps included with factory fresh Android that will install these apps as long as the user has chosen to allow it. This is how things like the Amazon app store work, which I have on every one of my Android devices even though none of them are rooted.
If the article can't get this right, and I know it is wrong, then I don't even want to risk exposure to bad information that I might not know enough to reject.
Back in the 1970's a friend who had been a medic told me about a spray clotting agent that was then saving lives called Topostat or Topistat. He found somewhere to buy it commercially and a few of up pitched in and got some spray cans. I never use it for more than patching up a scraped knee, but it seemed to be great stuff. Scrape you knee, spray on this stuff, and you had an instant scab to stop further bleeding.
I've never seen it again since, and even a search of the Internet seems to be completely ignorant of it. Apparently a Trademark was given for the name in 2004, but as that was about 30 years from when I saw the product that I had I'm thinking it is likely a different product. Anyone have any information on this product from the 70's?
Function reject.
