Free email detector API

Interesting little service: given an email address, detect whether it's a one-time use address.  Available via API.

More jQuery plugins than you can shake a stick at

If you use jQuery, then something here is surely going to be useful.

PostgreSQL and Redis

PostgreSQL can talk to anything.  Like Redis.

Learning things

OK, so flashcard learning is a discipline that has some serious history.  Here's a really refined flashcard algorithm that pumps words into your head.

On that note, another language learning program (a game, for Bulgarian).

Signal processing primer

What it says on the tin.

Rap Genius

This is slick, very slick: Rap Genius (link goes to transcript of second Romney/Obama debate) allows you to post lyrics to a song (or any other fixed text) and highlight individual words or phrases with popup notes.  (Its original name was Rap Exegesis, which I prefer.)  Neat idea!

They want to expand it to law, a great application.

Okapi workflow manager

Perusing my own blog over at Xlat-perl, I was reminded of Okapi's workflow manager.  It strikes me that this is where I want to go with the "low-level business process language" thing of files and directories and FTP servers I envision.  Tagged as "workflow" for lack of a better idea, although it's not really workflow without managing tasks for humans.

Bountify

Neat little programming-snippet bounty site.  Looks like some fun stuff there!  If it catches on, it'll be interesting to see how the data trends.  Tagged as a "job source" - but it isn't really that.  The bounties are more like prizes than pay.

PHP comment-style annotations not good

Nice post on PHP annotations in comments and why they're probably a mistake - but indicating that metadata in code is not a mistake.  And even offering an alternative that doesn't suck!

Personally I think treating PHP as the compilation target for a macro language is probably the better approach, but maybe that's a claim requiring extraordinary proof that I can't yet offer.

RJMetrics

Some sort of data science toolset?  Check it later.  Nice blog post!

Data structures

An open textbook in data structures.

Dbpatterns.com

Dbpatterns.com is a neat gallery/forking site for database patterns - it seems a little thin (you don't seem to be able to download patterns in a machine-readable form, for example), but the site itself is on Github and the idea is groovy.

Take that and make it machine-readable in a schema description format that can be composed and used to output SQL and man, I love it.

Deployment to a VM

So testing deployment should be pretty easy if I have a VM to test against.  (I'm looking at VMs again due to OpenLogos, natch).  The idea is basically to fire up a blank VM of the OS in question, then run scripts against it to build ... whatever.  The "whatever" then being a deliverable VM, but built using a deliverable, repeatable script.  And that script could then itself be an expression of the higher-level deployment description language I envision (and that already exists in other deployment tools).

Ah.  VirtualBox has a command-line interface.

Downloadable Oracle development VMs

Wow - this would have been nice back when I was developing an Oracle adapter for my workflow toolkit: Oracle now has downloadable development VMs available for their enterprise software, explicitly marked as no support and not suitable for production use but otherwise free of charge for development.

Very cool!

Data analysis languages

A very nice comparison of MATLAB/Octave, R, Julia, and a little Python at the end.

Syte: Personal site boilerplate (kinda)

Syte is a Github project that allows you to customize a few things and have a personal Django-based, mega-socially-interactive Website up on Heroku at breakneck speed.  You just fork it, run it, and customize it with its own tools.

Neat!

Pattern: Python web-mining system

Drool.  Of course, nothing restricts Decl to Perl...

Visualization in Perl (and not in Perl)

There was a post to the Quantified Onion group this week about visualization in Perl.  Here are some useful links that arose from that discussion.

• Gephi open-source graph visualization tool
• CPAN mapping

Another landing page tester

Here's a code-free landing page builder that gives you the ability to let customers select a pricing model preference during their interest registration.

Mingw package manager yypkg

The open-source takeover of Windows continues.
