How to find the area under a curve without calculus
- Ryan: guess how were taking the integral of these analog functions that come out of the gas chromatograph?
- Ryan: its one of those machines that scribbles a graph on a moving peice of paper, forget what that's called
- Ryan: but its how we measure the area under the graph that makes it seem really low tech for gas chromatography
- davidad: do you literally measure the area on the paper somehow?
- davidad: like by counting squares in the graph paper?
- Ryan: indirectly
- Ryan: but not literally
- Ryan: more precise than squares
- davidad: ah
- davidad: that's good at least
- Ryan: it's quite a clever idea for its simplicity
- Ryan: we carefully cut the graph out of the paper with scissors
- Ryan: and weigh it on an analytical balance
Metafora was so popular, I decided to write a second page. I don’t know if it’s as good as the first. If you want a third page, leave a comment. :-)
Explanations of selected Java exceptions
IllegalThreadStateException: One of the screws in your computer is threaded the wrong way.
CloneNotSupportedException: You are a clone. Find the original you, tell him what you want to do and then kill yourself.
ArrayStoreException: You have used up all your arrays and need to buy more from the array store.
EmptyStackException: In order for Java to work, you must have a stack of Java books on your desk. Actually, one is enough if it is really thick.
MimeTypeParseException: You are a bad mime. No one can understand what you’re supposed to be. Try something easier, like walking-against-the-wind or trapped-in-an-invisible-box.
NotActiveException: This can mean two things. Either something is inactive and needs to be active, or something is active and needs to be inactive. Activate and inactivate things randomly until things work.
