Get A Jump Start On Credit Card Processing from Ruby

4 Comments

By Matthew Lang / January 21, 2009

The development team behind the time tracking site freckle, have just released a PDF guide detailing the terminology and processes behind processing credit card details in Ruby.

Much like Amy Hoy’s previous guides relating to Rails, the Jump Start Credit Card Processing guide is a very colorful guide and is split into three small parts that make it easy to digest. It gives an overview of the process and actions involved in processing credit card payments as well as explaining different methods that can be used to validate a credit card.  A 6 step example in Ruby using the Active Merchant gem shows you the basic steps required to process payments.

Wicked Cool Ruby Scripts by Steve Pugh

Wicked Cool Ruby Scripts (or Amazon.com link – currently $19.77) is a new Ruby book by Steve Pugh that has just one goal: to share a bunch of “wicked, cool” Ruby scripts in various categories with readers. The publisher is No Starch and they offered to send me a copy for review.

First, No Starch Press is an independent technical book publisher (a rare entity nowadays) and if this book is any indicator, they have a real passion for producing books that are delightful to own. It’s so rare that you get nice paper in a book – here it’s thick and textured (and certified by the Sustainable Forestry Initiative). Read More

Euruko 2009 – The European Ruby Conference – May 9-10, Barcelona, Spain

euruko2009.png

Euruko is Europe’s annual Ruby conference. In 2008, it went down a storm in Prague, Czech Republic, with over 300 Rubyists attending, including Matz and the JRuby guys! Plans are now well underway for Euruko 2009, now scheduled for May 9-10, 2009 and being held in Barcelona, Spain. Matz is, again, confirmed as an attendee, so if you’re a European Ruby developer and fancy meeting Matz, this is the ideal chance.

Registration is not yet open but you can subscribe to the event’s feed (note to event organizers – please get some sort of pre-registration up before getting us to mention your event – you’re losing registrations!). Read More

What’s Hot on Github – January 2009

10 Comments

By Zach Inglis / January 14, 2009

GitHub LogoWhat’s Hot on Github is a monthly post highlighting interesting projects that are new or updated this month, within the Ruby community that are hosted on Github. Github has become an extremely popular place for Ruby and Rails developers to congregate over the last year, so I wanted to list some of the new projects, and some of the updated ones that I have found interesting.

This month’s picks:

Wikipedia Needs Rubyists to Flesh Out Mobile Vision

9 Comments

You might know Hampton Catlin as the Rubyist who invented the Haml markup system (as used in many Ruby web apps), Sass or make_resourceful. What you might not know, however, is that Hampton went on to develop a successful Wikipedia iPhone app (iPedia née iWik – listen to this podcast about its development) and was then hired by Wikipedia to lead the development of the mobile Wikipedia site (powered by Ruby!)

Hampton has been taking Ruby into Wikipedia in a big way and he needs the help of other Rubyists to keep the momentum going. I caught up with Hampton to find out what he’s doing at Wikipedia, what Wikipedia needs, and how Rubyists can get involved:

5 Ruby / Rails Jobs for January 2009

By Peter Cooper / January 11, 2009

Looking for a job where you can work on Ruby and Rails apps? You’re in the right place! Recently we’ve had several Rails-focused positions added to the Ruby jobs board. Alternatively, if you’re a company looking to hire Ruby and Rails developers and you’re in the US, head over to the job board too – it costs $150 for 60 days of exposure, and your jobs get featured in a post like this too!

This month’s interesting opportunities:

bdb: Improved Ruby Bindings for Berkeley DB

5 Comments

By Peter Cooper / January 9, 2009

berkdb.png Berkeley DB is a high performance database system initially developed in the early 1990s. It’s not an SQL driven database engine – it just stores data in key/value pairs – but BDB is very fast, available to use on most operating systems, and is dual licensed for open source and commercial use. It has several benefits to just using a flat file or a PStore: transactions, fine-grained locking, replication, and hot backups, for starters.

While Ruby bindings already exist for BDB, Matt Bauer has just released some all new shiny ones that are fast and easy to use. You’ll need to have Berkeley DB installed as a library on your system before you get started, of course. Read More

DebGem – Ruby Libraries Packaged for Debian and Ubuntu

49 Comments

By Peter Cooper / January 6, 2009

debgem.png Phusion, the company responsible for Passenger – the Rails deployment system, has today announced DebGem, a “RubyGem to APT conversion service.”

Many Debian (and Ubuntu, which is compatible) sysadmins and users prefer to use the APT (as in apt-get) package management system for handling the installation of everything on their system. With its separate RubyGems packaging system, however, Ruby can cause a dilemma. While some Ruby stuff is available through the regular repositories, it can be out of date and unreliable. No longer.. DebGem provides an APT repository with Debian and Ubuntu packages for “virtually all gems” available on RubyForge and Github. Read More

SourceClassifier: Identifying Programming Languages Quickly

8 Comments

By Peter Cooper / January 5, 2009

If you’re developing a snippets or pastie-type system or another form of CMS where source code might be stored, it’d be incredibly useful to automatically detect what language a provided source is in so that you can style it appropriately.

Chris Lowis’ SourceClassifier (or Github repo) library does just that, using a Bayesian classifier trained on source code from the Alioth Shootouts. Out of the box it has support for C, Java, JavaScript, Perl, Python and Ruby, but you can train it to recognize others (CSS and HTML seem like notable omissions to me). Read More

How to Sanitize HTML and CSS in Ruby

By Peter Cooper / January 1, 2009

If you’ve developed an application that displays user-supplied text in a Web browser, it’s always possible that the user has entered some crazy HTML (or even CSS) that will break your site’s layout. While it’s easy to remove all HTML from a piece of text, you might want them to use certain subsets of HTML to format their content, so you need to sanitize the user supplied HTML and CSS. Luckily, two Ruby libraries have been released in the last couple of days to sanitize HTML and CSS respectively.

Sanitize (or Github repo) by Ryan Grove is a new HTML sanitization library for Ruby. Read More

Giles Bowkett – Controversy, Excitement, and Awesomeness in 2008

Giles simply had to feature in Ruby Inside’s Top 10 of 2008 and since there’s no Top Crazy Mofo category, he instead scores for this excellent presentation at RubyFringe (yes, it’s all there to watch online, thanks to InfoQ!) Despite nominatively being about his “semi-autonomous Ruby musical instrument” Archaeopteryx, the presentation is really about building up an ecosystem around your passions – something most of us can relate to.

CloudKit: RESTful JSON Storage Rack Appliance

2 Comments

By Peter Cooper / December 23, 2008

cloudkit.gif Apologies for the buzzword collision in the title, but Cloudkit really is a RESTful JSON-powered storage appliance that uses Rack! Think of it as a schema-less, HTTP accessible database of sorts – like CouchDB without some of the more advanced features. It’s all written in Ruby and makes it ridiculously easy to set up a fully discoverable, RESTful, JSON API.

In the Release: CloudKit 0.9 blog post, developer Jon Crosby demonstrates how easy it is to get Cloudkit up and running. Just two lines in a config.ru file and you’re ready to roll with the basic featureset. If you want to add OpenID and OAuth support, just change a word and it’s all running. Read More
