• speed of map() vs. list comprehension vs. numpy vectorized function in python

  - by mcstrother

  I have a function foo(i) that takes an integer and takes a significant amount of time to execute. Will there be a significant performance difference between any of the following ways of initializing 'a': a = [foo(i) for i in xrange(100)] , a = map(foo, range(100)) , and vfoo = numpy.vectorize(foo) vfoo(range(100)) ? (I don't care whether the output is a list or a numpy array). Is there some other better way of doing this? Thanks.

  - by JoshL

  .Net defines a "Trace Source" concept, allowing configuration files to specify which trace sources to listen for messages on.

• jQuery: What to do with the list that sortable('serialize') returns?

  - by bartclaeys

  With jQuery I'm retrieving positions of a sortable list using 'serialize', like this: var order = $('ul').sortable('serialize'); The variable 'order' then receives the following: id[]=2&id[]=3&id[]=1&id[]=4&id[]=5 Now how can I use this data in an ajax call? This is how I plan to do it, but it's ugly and I can't change the parameter name 'id': $.post('ajax.php?'+order,{action:'updateOrder'}); Maybe I need to unserialize, then implode the variable 'order' and assign it to just one parameter?

Is there a fast way to list all files in a repository with the latest revision number?

• Looking for a script/tool to dump a list of installed features and programs on Windows Server 2008 R

  - by Hamish Grubijan

  Hi, The same compiled .Net / C++ / Com program does different things on two seemingly same computers. Both have DOZENS of things installed on them. I would like to figure out what the difference between the two is by looking at an ASCII diff. Before that I need to "serialize" the list of installed things in a plain readable format - sorted alphabetically + one item per line. A Python script would be ideal, but I also have Perl, PowerShell installed. Thank you.
