First, Fully Functional Ruby 1.8 Compiler Now Complete

2 Comments

By Peter Cooper / September 28, 2007

Charles Nutter says:

It is a glorious day in JRuby-land, for the compiler is now complete.

But not only is it a glorious day in JRuby-land, but in Ruby-land proper as Charles has announced that the JRuby-based Ruby 1.8 compiler is now “complete!” Excellent work guys. This is still early days, but with the leaps being made by both the JRuby, Rubinius, and Ruby 1.9 teams as of late, the state of Ruby interpretation and compilation is set to radically evolve over the next year. No longer shall our runtimes be mocked by the Pythonistas! Read More

How Not To Build An E-Commerce Site With Rails

25 Comments

By Peter Cooper / September 24, 2007

Derek Sivers, quite the Rails champion when he decided to rebuild his CD Baby e-commerce site using Rails two years ago, has now admitted defeat. After two years of wrestling with Rails while building the new site, Sivers along with coder Jeremy Kemper, decided to face up to reality. Kemper went off to 37signals and Sivers rebuilt the entire site in PHP in just two months. As such, Slashdot is jumping on the bandwagon by telling developers to “think again” about using Rails in future. Read More

RailsConf Europe 2007 is over and it’s time to wrap up. As before, there are oodles of pictures on Flickr with the “RailsConfEurope” tag (yah-boo to you miserable sods who don’t use Creative Commons licenses for your photos) and DHH points to all of the presentations given at the conference (covering areas as wide as Ferret, REST, Adobe Flex, Amazon S3 and JRuby). Continuing from his fine coverage of Monday, the first day of the conference, Robert Dempsey succinctly wraps up the Tuesday morning and afternoon sessions, as well as the Wednesday morning sessions, and then Wednesday in its entirety.

Serving PDFs with Rails using Inkscape Satya X has written “Serving PDFs with Rails using Inkscape,” an article that goes into amazing detail about how to set up a system where customized PDFs can be created and served from a Rails application (or any Ruby app, with amendments).

The European variety of the popular RailsConf Rails Conference is currently in full swing in Berlin, Germany, and runs until the end of this Wednesday, September 19. But for those of us who prefer to watch Yanni concerts on DVD from the comfort of our couch rather than from the ear-pounding front row, some attendees have been uploading photos and blog posts about the event so far.

An announcement about the Reject Conf tonight (September 18) in Berlin. The Reject Conf in Portland was supposedly a total blast, so check it out. It’ll feature some of the talks that didn’t make the list for RailsConf proper. Read More

Staticmatic

StaticMatic is a new alternative to dynamic systems like Ruby on Rails for putting together regular, static Web sites. It uses the superb Haml templating language, and if you’re of the Haml mindset, StaticMatic makes putting together static Web sites a snap. It also allows you to quickly “preview” your sites using a stand alone daemon but also to “build” your site to HTML to upload elsewhere. Read More

Anvil1
Anvil is a new Ruby framework for developing GUI applications by Lance Carlson. It’s a framework around Wx::Ruby (WxWidgets is a popular cross-platform widget toolkit) and offers its own DSL to make developing GUI applications easy. The release blog post has more information, including a great example of the code required to make a basic Anvil app. Interestingly it supports an MVC style of development where the view and control elements of your applications can be separated cleanly.

The first Anvil-powered application is a Ruby based editor called Hamr. Lance is so far the main developer of the Anvil project but he’s keen to get other people involved. Read More

Welcome to the first “Interesting Ruby Tidbits That Don’t Warrant Separate Posts”! This is going to be a somewhat regular feature of all the reasonably interesting things I’m e-mailed about or discover that aren’t getting as much attention as they should, but which aren’t captivating enough to warrant an entire post on their own. So without further ado..thread-dump librarythread-dump is an interesting library that lets you to get a dump of thread activity when a Ruby process quits by Greg Fodor. In his own words:
It allows you to send a SIGQUIT to a ruby process to get a dump of the running threads to STDERR or a file. Read More

Bloom Filters: A Powerful Tool

BloomFilter is a new Ruby library (available as a gem – gem install bloomfilter) by Bryan Duxbury that provides operations to create and query “bloom filters“, an extremely space-efficient “probablistic data structure” that makes it quick and easy to test set membership. This all sounds incredibly geeky and uninteresting until you discover how bloom filters can be used to make things like ultra-fast, low-overhead spell checkers, spam filters, stop word removers, and other tools that require checking two sets of data against each other. Bryan’s use for bloom filters (and BloomFilter) was to search a big list of 500 million hashes against a set of 40 million hashes. Read More

Just over a month ago I mentioned the release of “Shoes”, a new Ruby library for creating “Web-like desktop apps” by Why The Lucky Stiff. Shoes provides a somewhat platform-independent way of creating desktop applications easily. Now that Shoes is several weeks old, it’s worth pointing to a few resources and tutorials that will come in useful if you decide to start building Shoes-powered apps:

Running with Shoes – A Mini GUI Toolkit by Juixe: A great walkthrough building a simple Shoes application.

Cut Holes in Shoes and Get A Mask by Why The Lucky Stiff: A demonstration of using masks to create fancy text graphics. Read More
