• Dynamically resizing CFWINDOW to fit content

  - by Ryan French

  Hi all, Am currently working on a site that uses a lot of cfwindow objects and I was wondering if anyone knows of a way to dynamically resize the window so that all the content fits in without the need for scroll bars. I have tried using the overflow=visible configuration but it doesnt seem to make a difference. Thanks in advance for any advice.

• Will First() perform the OrderBy()?

  - by Martin

  Is there any difference in (asymptotic) performance between Orders.OrderBy(order => order.Date).First() and Orders.Where(order => order.Date == Orders.Max(x => x.Date)); i.e. will First() perform the OrderBy()? I'm guessing no. MSDN says enumerating the collection via foreach och GetEnumerator does but the phrasing does not exclude other extensions.

• Qt releasing memory occopied by unneeded images

  - by Gerhman

  I have a QML Flickable with 3 QML image elements that cycle through 8 image files. My problem is for each new image it loads into memory it does not release the the unused image. This is causing memory usage to become double what is necessary at times. I would like to know if there is some function I can use to force it to unload all the unused images? If it makes a difference, this is mainly for Symbian.

• Which DateTime module is best for manipulating an XML date and time

  - by justintime

  I am trying to parse a date from a GPX (XML track format) that looks like 2009-08-02T12:11:06Z My initial approach was to use DateTime::Format::RFC3339 But DateTime:Format::XSD seems to do a similar job. Is there a difference between the applicability of these modules.

• Python `if x is not None` or `if not x is None`?

  - by orokusaki

  I've always thought of the if not x is None version to be more clear, but Google's style guide implies (based on this excerpt) that they use if x is not None. Is there any minor performance difference (I'm assuming not), and is there any case where one really doesn't fit (making the other a clear winner for my convention)?* *I'm referring to any singleton, rather than just None. ...to compare singletons like None. Use is or is not.

• Emacs bulk indent for Python

  - by Vernon

  Working with Python in Emacs if I want to add a try/catch to a block of code, I often find that I am having to indent the whole block, line by line. In Emacs, how do you indent the whole block at once. I am not an experienced Emacs user, but just find it is the best tool for working through ssh. I am using Emacs on the command line(Ubuntu), not as a gui, if that makes any difference.

  After some searching in google and wikipedia, I still can not get a clear image about the "difference" between BRMS (Business Rule Management System) and BPM (Business process management)/workflow system. can those two concepts do the same thing from each other?

• Example of xargs' -x option in action

  - by Ole Tange

  GNU xargs has option '-x'. The man page says: -x Exit if the size (see the -s option) is exceeded. But xargs seems to not care if -x is set or not. I have been unable to make an example in which the -x has any effect at all. Please provide two examples in which the only difference is an added -x and that produce different output.

  Came across a line in OpenSSL that made me do a double take... if (!*pos) return NULL; if (!*pos || ((*pos)->flags == FLAGS)) return blah; Is there a (performance/security/concurrecy) difference in doing that instead of: if (!*pos) return NULL; if (*pos && ((*pos)->flags == FLAGS)) return blah; Thanks, Chenz

• Reflection: different ways to retrieve property value

  - by jules

  I'm retrieving an IEnumerable list of properties via following code: BindingFlags bindingFlag = BindingFlags.Instance | BindingFlags.Public; var dataProperties = typeof(myParentObject).GetProperties(bindingFlag); Then I'm iterating through the list and retrieving the value for each property. I've come across two different approaches to doing this, and just wondered what the difference is between them: 1) object propertyValue = property.GetGetMethod().Invoke(myObject, null); 2) object propertValue = property.GetValue(myObject, null)

• List comprehension, map, and numpy.vectorize performance

  - 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)) vfoo = numpy.vectorize(foo) a = vfoo(range(100)) (I don't care whether the output is a list or a numpy array.) Is there a better way?

• Page rendering time are not steady in IE6

  I have to support IE6 and I calculate rendering time by creating a timestamp in javascript at the beginning of the page and doing the difference when document.ready is fired in jQuery. If I do 3 pages load, the rendering times in milliseconds can look like this : page 1 : 735, 2672, 734 page 2 : 3063, 1516, 3375 page 3 : 8281, 2531, 3703 Why is that? How can I have more consistency?

  - by DevNovice

  I'm new in C# and earlier I saw the lambda expression is like (params) = { expression;} but in LINQ, I saw examples like IEnumerable customerFirstNames = customers.Select(cust = cust.FirstName); No brackets. Are they the same or is there any difference? Thanks a lot.
