    Good guesses both! And close! It's a Geiger counter. (I'm not sure if what you posted is exactly the same thing, but I'm guessing the two are a little different?) As for why I bought one: There are a significant number of camera lenses produced from the 1940s through the 1970s that are measurably radioactive. Main source of radioactivity is the use of thorium oxide (up to 30% by weight) as a component of the glass used in the lens elements. Thorium oxide has a crystalline structural similar to calcium fluoride (fluorite). Like fluorite, its optical properties of high refractivity and low dispersion allows lens designers to minimize chromatic aberration and use lenses of lower curvature, which are less expensive to produce. Typical radiation levels can approach 10 mR/hr (100 μSv/h) as measured at the lens element's surface, decreasing substantially with distance; at a distance of 3 ft. (.9 m.) the radiation level is difficult to detect over typical background levels. For reference, a typical chest x-ray consists of about about 10 mR, a round-trip cross country airline flight exposes a passenger to 5 mR, and a full set of dental x-rays exposes the patient to 10 mR to 40mR. However, as thorium 232 ages, it begins to decay to “daughter particles” which emit beta radiation, and apparently also gamma radiation, making them more dangerous as they age. Basically, tl;dr: Many vintage camera lens manufacturers doped the glass with thorium. As these things age, they emit more and more beta and gamma radiation, making them more dangerous, especially to your eyes. Overall, actual level of risk from these things, depending on whom you ask, ranges from "it's a ridiculous thing to worry about" to "might wanna keep an eye on them, they get more dangerous over time." My thing is, because I can choose to either own or not own camera lenses that are fucking radioactive, I'm going to choose the latter option. I tested all of mine, and all of my FIL's. All were fine except for one, which was emitting twice as much radiation as background levels. Not enough to be a cause for alarm, but nonetheless we're going to sell it. Why even bother.

    @loki said in Facebook data leak: Another pro tip is also to have only your contacts actually ring. That's built in (as an option) in iOS. If you turn it on, non-contacts never ring, buzz or anything. They have the option of leaving a voicemail, of course.

    So it is President Trumps fault? This risky funding was stopped under President Obama administration, resumed under President Trump administration. George K, I think you have TDS!!!! LOL (Just kidding!!! :couplekiss: )

    Yes, of course You can hope that they don't think about race the way they pretend to think about race.

    @catseye3 said in The rehabilitation of Hunter Biden: @jolly Conclude whatever you like. My give-a-damn button busted when I realized I live in a country that saw fit to put Donald Trump in my White House. I’ll get it fixed one of these days. Until then I’ve got my own fish to fry. I'm sorry the people who saw fit to vote for Donald Trump, are breathing the same air as you do, m'lady. They're just poor ignorant folk that simply cannot compete with the wonders of your intellect and wisdom. Mostly middle class Americans that thought the country had swung too far to the Left, who valued social conservatism and thought that some of the customs and traditions they held dear, were worth preserving. You know, morons. Seventy million and more.

    Here, you have to have an ID to vote. Vote by mail is possible and quite popular (in the last elections, >50% of the votes were via mail). The election system is no political issue whatsoever. It's a complete non-issue.

    It’s in the fifth generation of our family at least. Every Easter without fail. Begins day before. Egg dying, then egg decoration and one fighting egg. I have results going back to the 1970’s of the winner for every year. Several winners are no longer with us and get the mention at the table. We don’t knock. We tap. Lots of subterfuge and it’s become an art form. Eggs are inspected for illegal PE’s, such as nail polish...

    Lol "Often it really pays to have a look at the assembler the compiler is producing to check whether your branchless code is giving any benefits". He misspelled "this is a useless technique, of interest only out of curiosity because compilers are better than you are at this anyway. Also, if you find yourself interrogating your compiler's assembler output for efficiency, I hope you're programming for a nuclear reactor where milliseconds count, and then asking yourself why you're using some random implementation of a c++ compiler anyway". That's quite a misspelling, but it can happen. The probability of it happening is the same as the probability of a branchless technique being a good idea in modern software programming. I'm old enough to have used inline assembly in Borland Turbo c++, for a game I wrote that wrote directly to the VGA Mode-X graphics buffer. I bought a book by Michael Abrash that explained how.
