I'm an avid programmer, enjoy creating things, enjoy a good puzzle and especially enjoy foxing people with a Java puzzle now and again!

Outside of my coding life, I have a number of other interests, including outdoors activities such as hiking / geocaching / letterboxing. I'm also fond of music - I enjoy listening to it as well as playing the piano and violin.

Still no major browser support, but it has re-emerged in the HTML5.1 draft: w3.org/TR/2016/WD-html51-20160310/…

comment Casting variables in Java
@林果皞 You're just using casting in this case to promote a primitive - this is not the same as going to a more general type, and a very odd way of doing things. The more normal (better) way would be Double.valueOf(gpsLastLoc.getLatitude()).getClass().getSimpleName(). In either case, you shouldn't ever need to get the class of a primitive dynamically, since if getLatitude() returns a double primitive, you always know it's going to promote to a Double object.

@SpheroPefhany Quite possibly - for better or worse, I've just always had it bashed into me that the datasheet is never wrong :)

comment What resistor values should I use for a voltage divider that has to operate at low temperatures?
The datasheet extract I quoted definitely says "because of the leakage path on PCBs", so I'd say it made the relation quite explicit! This was part of my confusion, as I also didn't see the correlation between temperature and leakage paths. I had no idea about the gain of BJTs dropping with temperature decreases either though so thanks for that - interesting to note!

@placeholder Sorry - should have added that to the quote.

@PlasmaHH No schematic yet as I'm just researching components - but how is it that temperature affects the leakage path, in either case?
