    My snipplet for an if/then/else in shell scripts looks like this: if true then : else : fi The colons make that code syntactically complete, w/o the colons you run into a syntax error. The colon is the “null op” of (Bourne) shell scripting. And the colons usually remain there for the remainder of the…

    You do know the result of this: a=A; echo $a But are you just as sure here? a=A; b=B; echo $a.$b That depends on the shell, you are using. So I suggest you better write it this way: a=A; b=B; echo ${a}.${b} Enclosing variable names in curly braces is quite often a good idea. Look…

    See its manual page at CPAN! The installations with/for my self-brewn perl-5.12.1 on openSUSE-11.2 as well as on OS X Snow Leopard have a problem with Task::Kensho‘sTryCatch, I skip that, and all the remainder seems to be fine. The installation with/for my self-brewn perl-5.10.1 on openSUSE-11.2 runs straight through. The installation with/for the “native” perl-5.10.0 on my openSUSE-11.2 runs straight through.

    Ads are actually BLOCKED FROM DOWNLOADING now, instead of just being removed after the fact! One of these milksops told me “the other day”, that wouldn’t be true, and I couldn’t prove him wrong then. It hurts having trusted yet another shameless lie. If you notice Google Chrome as a tag here, that means, there…

    I have the DocBook XSL book in front of me (opened at “Chapter 31. Website“), asking myself and the world (irc://irc.freenode.net#docbook) silly questions, like the ones, you can find as my recent articles on this blog. I want to change a couple of pretty raw vanilla DocBook web sites to pretty raw but neat vanilla…

    I found it at SourceForge. I really love editing XML in Emacs’s nxml-mode. I did mention that at my DocBook Wiki home page already.
