• Why does this eval not work in Ruby

  - by Ashwin Prabhu

  @Override public boolean equals( Object otherObject ) is not allowed in Java for an Enum, since the method equals(Object x) is defined as final in Enum. Why is this so? I cannot thing of any use case which would require overriding equals(Object) for Enum. I'm just curious to know the reasoning behind this behavior.

• How to match a variable list of items separated by commas

  - by user261915

  I want to turn something like this CS 240, CS 246, ECE 222, ... (more or less); Software Engineering students only into ('CS 240', 'CS 246', 'ECE 222', 'ECE 220') in Python, code that matches a single course looks like >>> re.search('([A-Z]{2,5} \d{3})', 'SE 112').groups() ('SE 112',) I prefer a regular expression only method because I have a bunch of other alternate reg exps using '|' to combine them. However, a method with split is acceptable.

• "Slice" out one element from a python dictionary

  - by BCS

  I have a dictionary: D = { "foo" : "bar", "baz" : "bip" } and I want to create new dictionary that has a copy of one of it's elements k. So if k = "baz": R = { "baz" : "bip" } what I'v got now is: R = { k : D[k] } But in my case k is a complex expression and I've got a whole stack of these. Caching k in a temporary looks about as ugly as the original option. What I'm looking for is a better (cleaner) way to do this.

• Is there a way to look up the Publishers URL using the linkshare.com API

  - by steve

  I'm able to retrieve the URL of a publisher only if their URL is in the title or the description using regular expression in linkshare's coupon API but in doing so, that leaves me with a lot of publishers not having a reference to their website which I need for the type of site that I am building. I was wondering if anyone else knows a way to reference the publishers URL preferably by their publisher ID or some other way?

• C++ Question on the pow function.

  - by Sagistic

  I'm trying to get this expression to work, I'm pretty sure its not the parenthesis because I counted all of them.

• java swing, simulate JTable terminateEditOnFocusLost behaviour

  - by blow

  Hi all, i'm using putClientProperty("terminateEditOnFocusLost", Boolean); to make jtable end editing and clear current selected rows when it lose focus or when simply click over an other GUI component. This is very useful, but with "terminateEditOnFocusLost" there are some strange behaviours if it is used with editCellAt and changeSelection. There are also some undesiderable TableModelEvents fired for some fake table updates. So, im looking for an hack to simulate "terminateEditOnFocusLost without using it, is this possibile? Thanks all.

• How to match !x but not !!x in JS regex?

  - by mpeterson

  Given the following text: This is!!xa simple string!xpattern I would like to get a regexp that matches the !x that's between "string" and "pattern" but not !!xa that's between "is" and "a". This regexp is to be used inside a string split(). I have tried several combinations but I cannot get a regexp that meets my needs. Perhaps my expression is not so regular after all =) Thanks in advance!
