The Fretboard is a pretty simple Arduino project that visualizes the build status of up to 24 projects with an addressable LED array. The latest incarnation of the project is housed in an old classical guitar … hence the name ;-)
All the code and design details for The Fretboard are open-source and available at fretboard.tardate.com. Feel free to fork or borrow any ideas for your (more...)
cancannible is a gem that has been kicking around in a few large-scale production deployments for years. It still gets loving attention - most recently an official update for Rails 4 (thanks to the push from @zwippie).

It is a pretty common pattern to branch depending on whether a query returns any data - for example to render a quite different view. In Rails we might do something like this:
query = User.where(deleted_at: nil).and_maybe_some_other_scopes
if results = (more...)
So the best swag you can get from a technology conference is code, right? Well RedDotRubyConf 2013 did not disappoint! Thanks to some fantastic speakers, my weekends for months to come are spoken for. Here's just some of the goodness:

The third RedDotRubyConf is over, and I think it just keeps getting better! Met lots of great people, and saw so many of my Ruby heroes speak on stage. Only thing that could make it even better next year would be to get the (more...)
Megar (“megaargh!” in pirate-speak) is a Ruby wrapper and command-line client for the Mega API.
In the current release (gem version 0.0.3), it has coverage of the basic file/folder operations: connect, get file/folder listings and details, upload and download files. You can use it directly in Ruby with what I hope you'll find is a very sane API, but it also sports a basic command-line mode for simple listing, upload and download tasks.
If you are interested in hacking around with Mega, and prefer to do it (more...)
Mandrill is the transactional email service by the same folks who do MailChimp, and I've been pretty impressed with it. For SMTP mail delivery it just works great, but where it really shines is inbound mail handling and the range of event triggers you can feed into to your application as webhooks (for example, to notify on email link clicks or bounces).
The API is very nice to use, but in a Rails application it's best to keep all the crufty details encapsulated and hidden away, right? That's what the mandrill-rails gem (more...)
Wow. This year we mark the 20th anniversary of the Visual Basic 3.0 launch way back in 1993.
It's easy to forget the pivotal role it played in revolutionizing how we built software. No matter what you think of Microsoft, one can't deny the impact it had at the time. Along with other products such as PowerBuilder and Borland Delphi, we started to see long-promised advances in software development (as pioneered by Smalltalk) become mainstream reality:
So eBook sales have surpassed hardcover for the first time, and it is no surprise that the rise of the tablets is the main driver.
There's something quite comfortable about having a nice digital bundle of information at your fingertips, like warm buttered toast.
With relatively open standards and the ubiquity of ereaders, the ebook has become ideal packaging for all manner of information, from training manuals to open source project documentation. Or even that book that apparently 81% of us believe we have inside.
It's been a while since I last cranked up mono to compile some C#, and this time I'm on a Mac.
Fortunately, no dramas. The mono team have made it a very smooth process. I simply downloaded and installed the Mono SDK (it is packaged as a standard disk image [.dmg]). That's enough to compile and run simple projects.
$ mcs hello_world.cs
$ mono hello_world.exe
There's a whole cross-platform IDE available now called MonoDevelop and it looks great if you are doing serious C#. Right now though, I was happy enough to build from the command (more...)
