Try rakudobrew and play with concurrency

rakudobrew is similar to perlbrew, but it's for Rakudo (a.k.a., Perl 6), the Perl-inspired language that we've all come to have a love/hate relationship with. I urge you to try it out, but first, some interesting new developments that you should probably know about.

Quickly Check for Database Design Flaws

Don't you just hate it? You've finished reading, again, that blog entry about database design and you're feeling that you can design something reasonable, and then you see this table:

EmployeeID| SalesPerson| SalesOffice| OfficeNumber| Customer1| Customer2| Customer3
1003 Mary Smith Chicago 312-555-1212 Ford GM
1004 John Hunt New York 212-555-1212 Dell HP Apple
1005 Martin Hap Chicago 312-555-1212 Boeing

You can easily see that Customer1, Customer2, and Customer3 are wrong, but what about the rest? Try as you might, you can't quite put all of the rules together that easily to figure out what's wrong with the above table.

There's a shortcut, though, and it makes it very easy to start understanding database design.

Creating an MMORPG in Perl

Question: do you want to hear more about my attempts to create an MMORPG in Perl, even if posts are not Perl-related? Also, are you interested in helping me develop its ideas further?

As many of you know, I'm trying to create an MMORPG running on Perl. It's codenamed veure. Though I've written about it a few times here, I've not written much because many of the entries are about game design and not strictly about Perl. As a result, I've tried to avoid spamming this blog. That being said, people constantly say "stop talking about how great Perl is and build great things with it!" So I'm trying to build something great with Perl, but as most experienced programmers know, it's not so much the programming language as the business rules which are important.

And damn, business rules in an MMORPG are hard.
