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)
- To force an update of the system clock: ntpdate pool.ntp.org
- 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.
Things You Must Know
In Linux, you often run into things which you Just Have To Know in order to make things work; there is not really any way to find them out. This is bad UI design, but for now it's the situation. I will be listing them here as I find them out.
- When Perl is missing a module, the package name is always (I am told)
"perl-libraryname". For example, for Tk.pm, the package is perl-Tk. So in Fedora you would type "yum install perl-Tk". Presumably in debian-derived distributions, you would type "apt-get install perl-Tk", though I have not actually tested this. (Remember that package names, like Linux filenames, are case-sensitive, so that T must be uppercase or it won't work.) If the library is within a Perl package, e.g. Net::Telnet, then the format is perl-Package-Library, e.g. perl-Net-Telnet.
- To run a binary which is located in the current directory, from the
command line, you have to type "./" before the binary's name. It's not clear why this is.
