  javascript google-maps animation google-maps-api-3 google-maps-markers
  I have a simple javascript maps application that I’m working on that requires me to animate the movement of multiple markers between different coords. Each marker is free to move on its own and all markers are stored in an array list. However, I have been having trouble getting them to smoothly transition locations.I’ve done a ton of research and trial/error but no luck, anyone have any luck with this?

  javascript jquery html scrolling mobile-browser
  I am trying to scroll to a specific location in a scrolling DIV. Right now I am using a pixel offset with the jQuery scrollTop() function which works great on desktop browsers but it does not work on android mobiles browsers with the exception of Google’s Chrome Android browser (do not have an iOS device to test if that works). All the solutions I have found are for page (window) scrolling and not for scrolling in a DIV, anyone have any suggestions on what else I can use to accomplish the same

  java regex string split
  I’m making a text based dice roller. It takes in strings like “2d10+5” and returns a string as a result of the roll(s). My problem is showing up in the tokenizer that splits the string into useful parts for me to parse into information.String[] tokens = message.split(“(?=[dk\\+\\-])”); This is yielding strange, unexpected results. I don’t know exactly what is causing them. It could be the regex, my misunderstanding, or Java just being Java. Here’s what’s happening: 3d6+4 yields the string array

  I have a string, say ‘123’, and I want to convert it to 123.I know you can simply do some_string.to_i, but that converts ‘lolipops’ to 0, which is not the effect I have in mind. I want it to blow up in my face when I try to convert something invalid, with a nice and painful Exception. Otherwise, I can’t distinguish between a valid 0 and something that just isn’t a number at all.EDIT: I was looking for the standard way of doing it, without regex trickery.
