• Login screen delay in CentOS 5.4 x64

  - by user208728

  I was happily running my CentOS 5.4 before something bad happened that somehow corrupted the 'nautilus' package. It stopped me from using the default Gnome Desktop. Then I installed (using yum) the KDE and nautilus later on. Now, KDE is running perfectly with one exception that it takes around 10 minutes before showing up the Login Screen and only a blue screen with mouse pointer keeps showing during those 10 minutes. Thanks in Anticipation. Regards, Talal

• enumitem font size

  - by user451854

  Is it possible to change a itemize font size after including enumitem package? I had: \setbeamerfont{itemize/enumerate body}{size=\small} \setbeamerfont{itemize/enumerate subbody}{size=\scriptsize} \setbeamerfont{itemize/enumerate subsubbody}{size=\scriptsize} but after I included the enumitem package the font size for itemize became default, as far as I see. \usepackage{enumitem} \setlist{label=\tiny\textbullet, leftmargin=1em, labelsep=*, labelwidth=0.2em, noitemsep, labelindent=\parindent, nolistsep} I cannot find anything related in enumitem documentation.

• How do I declare a constructor for an 'object' class type in Scala? I.e., a one time operation for the singleton.

  - by Zack

  I know that objects are treated pretty much like singletons in scala. However, I have been unable to find an elegant way to specify default behavior on initial instantiation. I can accomplish this by just putting code into the body of the object declaration but this seems overly hacky. Using an apply doesn't really work because it can be called multiple times and doesn't really make sense for this use case. Any ideas on how to do this?
