RESULT
unmoderated group comp.lang.ruby passes 200:16
There were 200 YES votes and 16 NO votes, for a total of 216 valid
votes. There were 5 abstentions and 2 invalid ballots.
For a group to pass, YES votes must be at least 2/3 of all valid
(YES and NO) votes. There must also be at least 100 more YES votes
than NO votes.
A five day discussion period follows this announcement. If no
serious allegations of voting irregularities are raised, the
moderator of news.announce.newgroups will create the group shortly
thereafter.
Newsgroups line:
comp.lang.ruby The Ruby dynamic OO programming language.
Voting closed at 23:59:59 UTC, 20 Apr 2000.
This vote was conducted by a neutral third party. Questions
about the proposed group should be directed to the proponent.
Proponent: Conrad Schneiker <schneiker@jump.net>
Votetaker: Dave Cornejo <dave@dogwood.com>
RATIONALE: comp.lang.ruby
Ruby is a very-high-level, dynamic object oriented programming language.
Ruby provides many of the best-liked power and convenience features of Perl
and Python on one hand, with an elegantly simple and powerful syntax that
was partly inspired by Eiffel and Ada on the other hand. Ruby is a more
thoroughly objected oriented language than Python, and some Ruby features
were inspired by Smalltalk. Ruby is an open source language.
There are over 1000 members of 4 Japanese Ruby mail lists (general,
developers, math, extension writers), with a peak volume topping 100
messages per day. At present, there is one English Ruby mail list with
about 175 members, with a recent volume often exceeding 10 messages per
day and growing. Many users of the Japanese Ruby mail lists have some
understanding of English and are also prospective comp.lang.ruby users
as well.
Much of 1999's newsgroup discussion of Ruby took place on comp.lang.python,
which is not optimal, since comp.lang.python is dedicated to the Python
language. For obvious reasons, Ruby users do not post there frequently. In
2000, most Ruby discussion has occurred in comp.lang.misc. This again is not
ideal since other comp.lang.misc regulars are typically more interested in
issues that transcend Ruby, and have said as much.
In Japan, Ruby has overtaken Python in terms of popular usage. During 1999
and into early 2000, Ruby has been featured in several articles in the
English language software trade press, indicating it is at the takeoff
threshold that Perl and Python attained years ago. (Please see
http://www-4.ibm.com/software/developer/library/ruby.html for the latest
example.) The English language Ruby home page is
http://www.ruby-lang.org/en/, which provides links to documentation and
download pages for Ruby.
CHARTER: comp.lang.ruby
The comp.lang.ruby newsgroup is devoted to discussions of the Ruby
programming language and related issues.
Examples of relevant postings include, but are not be limited to,
the following subjects:
- Bug reports
- Announcements of software written with Ruby
- Examples of Ruby code
- Suggestions for Ruby developers
- Requests for help from new Ruby programmers
The newsgroup is not moderated. Binaries are prohibited (except the
small PGP type). Advertising is prohibited (except for announcements
of new Ruby-related products).

various ways:
system 'notepad';
exec 'notepad'; # Perl script stops here
system 'start', 'somefile.txt';
The last one is cute. It will use the 'start' program to launch a file
as if it was doubleclicked. Cuter still: if the argument for 'start' is
a directory, this will open a window for this directory.
Happy experimenting.

Sounds as if you could use LWP::ParallelUA, which would let you avoid the
worries of threading and the worries of forking at the same time.

Message-Id: <8ec74q$tkm$1@nnrp1.deja.com>
Building URI-1.06 (latest version) having built Perl 5.6.0 cleanly on
WinNT4 SP6,
nmake test fails with
bless( do{\(my $o = 'file://C:/TEMP/')}, 'URI::file' )], 'URI::URL' );
Test Failed at t\old-base.t line 22
URI::URL::_expect('file://C:/TEMP/', 'as_string',
'file:C%3A/TEMP/') called at t\old-base.t line 675
This looks worryingly like something to do with the new Unicode stuff.
Last version of Perl I built URI on was 5.005_03, where there were no
problems. This has brought my mod_perl install on NT to a screeching
halt.
I could probably patch this problem but it worries me that this is
failing now under the supposedly latest 'stable' perl release. I am
wondering what else is gonna break in the various modules I normally
compile to build a full mod_perl. At the point of failure I had already
built HTML-Parser,CGI.pm,Mime::Base64 without any obvious problems. URI
is next on my normal sequence - I've done this several times before and
this is the first failure I've had.

There's some support for doing this with the B::Lint module, if your perl
is recent enough:
perl -MB::Lint -e '$x = lenght($y);'
Undefined subroutine &main::lenght called at -e line 1.
But a pragma to help facilitate this check could be useful, too, although
it would probably cause a small delay at the start of runtime. (Interested
parties: Yes, AUTOLOADed subs would be an issue. :-)

Since you are doing this in a cgi, I assume you plan to display $result
by embeding it in a page you are creating. Recall that HTML doe not
give a hoot about new line characters (\n). Something along the lines
of $result =~ s/\n/<br>/; will be needed to change the newlines in
$result to something usefull in HTML.

It decodes URL-encoded characters, e.g. %20, to whatever
character that represents (SPACE in this case).
Using the CGI.pm module (perldoc CGI) saves you having to
bother with putting stuff like this into your code.
Hand-coding of such CGI decoding usually brings in
potential buffer-overflows and security problems, not to
mention cluttering the solution with the problem.

This will match all occurences of "%" followed by two hex digits
(actually, it will match anything. We just hope it's two hex digits.)
For each match, $1 will be set to this string of two characters. And
then:
hex($1) will attempt to interpret it as a hexadecimal
number
pack "C", $number is Perl4-ism for chr($number)
i.e. convert number to character
Now, the options:
//e execute the right side as perl code
//g don't stop at one, but repeat for all matches
Example: matching "%2F"
* $1 is set to "2F"
* hex('2F') will turn this into the number 47,
* pack("C", 47) turns this into the character "/".
