CopyFS Update
Years ago I added features to CopyFS 1.0, then 1.0.1 came out and I never bothered to forward-port my changes. After spending some time moving, merging, rebasing, etc. in git this morning, CopyFS 1.3.1M is CopyFS 1.0.1 + CopyFS 1.3M. … Continue reading
Ruby Hash Extensions
As I mentioned before, one of the nice things about Ruby is its malleability. Here are a couple extensions to the Ruby Hash object: class ::Hash def random return self.keys[rand(self.size)] end def byValue(subKey) if subKey self.sort_by {|key, value| value[subKey]}.reverse else … Continue reading
Ruby 2 From Source on CentOS 6.4
Ruby‘s autoconf doesn’t alert you to the fact that your system doesn’t have everything it could use. It’ll blindly clear you even though, for example, nothing crypto-related will work. On a fresh CentOS 6.4 install (with EPEL) the following will … Continue reading
Which Oar Best Rows The Boat
Ted Dzuiba wrote a post that boiled down to identifying his own “language bigotry” as a step along the way to software engineering “Mastery”. He’s absolutely correct about introspecting why one chooses to “fight” other languages. And by saying “languages” I could … Continue reading

Ruby String.each
While I find Ruby to be a half-assed attempt at an object-oriented Perl, I have been using it quite a bit lately to stay consistent with a lot of existing intellectual property. One of the more maddening things is that … Continue reading
NConf 1.3.0 Pass-through HTTPD Auth

find -delete
If I hear one more person recommend using a pipe to xargs or -exec rm -f {}Â to the question “how can I make ‘find’ delete the files it finds?” I’m going to scream. It’s really simple: find /wherever -mtime … Continue reading
Caching Functions In Perl
Synopsis There are occasions, where you write a function that takes some parameters and outputs consistentish data. Example: sub add { my($first,$second)=@_; return $first + $second; } If you call add(1,1) you get 2: always. Consistent input yields consistent output. … Continue reading
Sorting Strings Ending In Numbers In Perl
Synopsis I deal with a lot of names that look like “somedumbserver2” and “somedumbserver15”. Using Perl’s default sort, “somedumbserver2” comes before “somedumbserver15” because the character “2” is greater than the character “1”, and that’s where the sort stops. This sort, … Continue reading
Fixing Mis-cased URIs Under Apache
Synopsis This is rather old code, but saved my bacon more than once.Runs under Apache with Mod_Perl, and corrects the URI requested when it is giving lazily. Thus a request for “/INDEX.HTML” is rewritten to “/index.html” as appropriate. Code =head1 … Continue reading
