HANDY ONE-LINERS FOR RUBY —

Nice list of Ruby one-liners when working at the shell. e.g., emulating nl(1):

# number each line of a file (left justified).
    $  ruby -ne 'printf("%-6s%s", $., $_)' < file.txt
# number each line of a file (right justified).
    $  ruby -ne 'printf("%6s%s", $., $_)' < file.txt
# number each line of a file, only print non-blank lines
    $  ruby -e 'while gets; end; puts $.' < file.txt

Unlike some other things, the -p and -e switches are something I’ve always been glad ruby adopted from perl.

Aristotle Pagaltzis comes through with the simple preforking echo server in Perl.

Extension/Scripting language comparisons - comp.lang.scheme —

“While I do consider the adjective ‘baroque’ to be a compliment, I must point out that Perl is actually more of a romantic piece, with allusions to various classical motifs. My favorite composer is Mahler, which should surprise no one.” — Larry Wall

Best. Program. Ever.

Maintainable Programmers —

This was a really great lesscode.org piece by Aristotle. The follow-up discussion in the comments was superb as well. Being in the middle of everything really warped my view of what was going on back then, I think.

Mistaking Cons for Pros —

chromatic on million-line Java programs: “I can only imagine how much larger the Java code would be without all of those XML files.”

Perl as a Web Scripting Language —

No, but seriously, the only reason we’re not all using Perl for web development is because all the problems are already solved … and have been since around 1995 or so. (See Also: mod_perl, libwww-perl, Fielding et al.)

depressing —

“maybe try coding something in c”

Mr. Peabody Explains fork() —

Brilliant!

Shell script awk csv file —

“I could whip you up something in Java that would take 2 minutes to design, 30 minutes to implement, a day to write the deployment descriptor for, and 3 months to get sign off from the app support people at the client site _b”
