How to impose maxlength on textArea in HTML using JavaScript
...st.
Inspired by, but an improvement over Dana Woodman's answer:
Changes from that answer are: Simplified and more generic, using jQuery.live and also not setting val if length is OK (leads to working arrow-keys in IE, and noticable speedup in IE):
// Get all textareas that have a "maxlength" pro...
Java Byte Array to String to Byte Array
...
You can't just take the returned string and construct a string from it... it's not a byte[] data type anymore, it's already a string; you need to parse it. For example :
String response = "[-47, 1, 16, 84, 2, 101, 110, 83, 111, 109, 101, 32, 78, 70, 67, 32, 68, 97, 116, 97]"; // re...

Difference between as.POSIXct/as.POSIXlt and strptime for converting character vectors to POSIXct/PO
...in the case of character, it runs strptime first, then does the conversion from POSIXlt to POSIXct.
It makes sense that strptime is faster, because strptime only handles character input whilst the others try to determine which method to use from input type. It should also be a bit safer in that bei...
