Fedora Project

Fedora Core 2

I like the new kernel (2.6.7-1.494.2.2)!

This is the first time I've actually noticed a dramatic improvement in responsiveness. Nice...

It also resolved a bug I reported.

Fedora Core 3

I installed FC3-test1 on a machine which already had FC2 so I could use both. Had to learn a little bit more about grub bootloader to achieve that. Nothing much to report about FC3. I was disappointed to find that "development" packages are not GPG-signed. Why not? Why should I trust that the mirrors have good copies of them?


Installed MoinMoin wiki engine at work and at home. I like it. Maybe this will force me to learn python... (I've had some vague ideas about playing with python for a while, but have never gotten around to it. I typically don't learn new languages until I'm forced to...)


Loving it! Running vss2svn right now...

GNU bash

Shell scripting hurts my brain.

$ echo foo!bar                 $ echo "foo!bar"
bash: !bar: event not found    bash: !bar": event not found
$ echo foo\!bar                $ echo "foo\!bar"
foo!bar                        foo\!bar
$ echo foo\\!bar               $ echo "foo\\!bar"
foo\!bar                       foo\!bar
$                              $ 

Must be a documentation bug, at least:

  Enclosing  characters  in  double quotes preserves the literal value of
  all characters within the quotes, with the exception of $,  `,  and  \.
  The  characters  $  and  `  retain  their special meaning within double
  quotes.  The backslash retains its special meaning only  when  followed
  by one of the following characters: $, `, ", \, or <newline>.

That explains some of what I thought was weird...

But it suggests that echo "foo!bar" should not be an error.

And I'd think that echo foo\\!bar should be an error.

(Tested on FC2 bash-2.05b-38 and FC3-test1 bash-3.0-1.)

New HTML Parser: The long-awaited libxml2 based HTML parser code is live. It needs further work but already handles most markup better than the original parser.
