You know one of them is going to be Damm impressed with porn on VR <| sep |> ayy , thanks 3 gives some <| sep |> I do have a device ! It ' s an oldie , an HTC Desire HD , but I ' m not sure how reliable the phone is anymore . The battery level goes from 100 % to 50 % within 15 minutes of using it , and completely dead by 25 minutes or so . Probably is my battery , needs replacing after all these years , ya ? This sounds pretty cool , I ' ll have to check it out , thanks ! <| sep |> Quick , someone Google that for him . <| sep |> Ah , you ' re right . Let me change the GTS request to Litten <| sep |> There is a process for calculating square roots I learned it at school ! . I also used a slide ruler in tech school in ' 83 . Calculators already existed , but weren ' t allowed , while slide rulers were , but nobody had them nor knew how to use . So being the prick I am , I went through the trouble of buying one and mastering its use more to annoy teachers than to practical use . I loved their faces when I pulled the ruler during an exam Most didn ' t know exactly what it could do haha . IIRC , my ruler did multiplication , division , logs any base , as you could quickly do two base 10 or ln and divide , square roots and squares , cubic squares and cubes , sin , cos , tan and all the other trigs came from the divisions of them , hyperbolic trigs which I still don ' t know the practical use for , and some other odd compound functions . Fun times .
