Learning music notes with Perl

Sun, 18 Dec 2011 14:02:00 GMT

So the other day I bought a MIDI2USB interface to my piano keyboard and as a programmer I was curious about sending back and forth those MIDI events. I decided to write a simple Perl game that can help to learn the music notes. The routine is simple. The random note is generated and printed out on the terminal (like D3), then you have to find that note on the keyboard and play it. If it matches you get ok, otherwise not ok. And so on. As always CPAN saved hours of my time.

Accessors are dangerous

So commonly used accessors (setters/getters) I think are dangerous when overused or used without a caution. Here is a quick list why.

PocketIO - realtime applications for Plack

Fri, 23 Sep 2011 12:43:00 GMT

PocketIO is a SocketIO port from Node.JS to Perl. It allows you to write realtime web applications without worring about specific browsers features: from long-polling to WebSockets.

PocketIO is built on top of AnyEvent and Plack, runs smoothly on Twiggy. This way it can be easily combined with other nonblocking Plack apps.

PocketIO can be scaled using Redis pub/sub infrastructure.

Proved to work well in production with 100-150 simultaneous connections. Works just fine with TLS/SSL (via App::TLSme) too.

Check it out. On Github or now on CPAN.

PerlWeekly - Quality Perl links

Thu, 22 Sep 2011 15:57:00 GMT

I've joined http://perlweekly.com/ as soon as it was launched. And since then I've enjoyed the quality Perl links every Monday. Not too few, not too many, just the right amount of news to check if I missed something during the week.

Articles, discussions, videos, events... I wish it had the most interesting CPAN updates or new Perl projects. Some unique content would be nice too, like interviews or short stories.

Little gifts are true

Fri, 02 Sep 2011 10:36:00 GMT

After reading rjbs' post on Promoting little gifts I remembered various gifts that I received from the users of my modules. For example I received a ebook from Jens Gassmann for working on PocketIO and today I got a thankful note and a donation from http://privytalks.com, the website that uses the same PocketIO in production (scary!). Funny that I can use something that uses something I wrote.

It's always nice to receive thanks and gifts. Thank you!

Perl Résumé

Wed, 24 Aug 2011 15:56:00 GMT

Lately I was playing with http://metacpan.org api. So I built a simple website that generates your Perl résumé based on CPAN experience, activity and impact. Runs on Dancer btw.

So check it out http://perlresume.org!

Any comments, suggestions and critics are as usual very very welcome.
