Issues

The following may reflect my own ignorance rather than an actual shortcoming in Linux:

• Development
  • There appears to be no mechanism corresponding to ActiveX (as used for desktop app development)
  • There appears to be no application corresponding to Microsoft Access. Yes, you can do all the same stuff with various available tools, but not quickly; v2.0 of OpenOffice is apparently going to include a tool which may be a step in the right direction...
• Regular Use
  • In Windows, if you create a link to an executable script (batch file -- *.bat) on your desktop (or anywhere), the link is executable with a double-click. Under KDE (in Ubuntu), I can't figure out how to make it execute at all without using a terminal.

How To

• Time Zone: If the KDE Clock-setting widget seems to be refusing to set the time zone (or your system clock is refusing to show anything except GMT time), this command may work:

ln -s /usr/share/zoneinfo/America/NewYork /etc/localtime

...where "/America/NewYork" should be replaced by the appropriate file for your time zone. I have not been able to find any documentation on this feature; the command was suggested to me by someone on the #kde forum at irc.freenode.net (see [1]). Remember to use the console "date" command to verify what the system clock is currently set to. --Woozle 08:45, 23 Apr 2005 (CST)

• Emptying the Trash: KDE does have trash-management built in, but it's not made obvious. You can do any of the following:
  • Navigate (in Konqueror) to "trash:/", then right-click on the panel showing the contents, and select "Empty trash".
  • Right-click on the applet panel and add the Trash applet, then left-click on it to use its various functions.
  • Create a new URL link on the desktop, give it the URL "trash:/", then right-click on it (my preferred solution). A trashcan icon is available in the "filesystems" icon group.
