Digital Digressions by Stuart Sierra
From programming to everything else
I couldn’t sleep last night. So I designed a RESTful interface for version control. Yeah, that’s weird. We already have a nice model for RESTful document storage in Amazon’s S3. But S3 doesn’t do versioning. What if it did? A PUT to a previously-unused URI creates a new resource with version number 1. Any subsequent…
Well, it happened. I ran out of space on the 250 GB drive I use to develop AltLaw. Not all that surprising, although it did happen sooner than I expected. I’m deleting gigabytes of cached data — file conversions, mostly — just so I can get enough space to work again. But this makes me…
I can’t help it. I just love big, complicated systems that let you get really precise about what you’re talking about. Types, classes, ontologies, schemas, normalization, denormalization, XML, RDF, XSLT, Java, … It’s all so cool. I can happily spend hours scribbling pages of hierarchies, interfaces, specifications, file formats, and the like. But at the…
Since I started working on AltLaw.org a little over a year ago, I’ve struggled with the data model. I’ve got around half a million documents, totally unstructured, from a dozen different sources. Each source has its own quirks and problems that have to be corrected before it’s useful. When I started, I was using MySQL…
The most famous piece of Lisp-related vaporware is vapor no longer: Arc has been released. After paging through the tutorial, I’m a bit underwhelmed. It looks like just a bunch of syntactic sugar implemented on top of Scheme. Clojure is more interesting and more innovative. Clojure and Arc have some things in common: data structures…
I finally found out how to do this, from the Rails Routing shortcut by David Black. In the Rails console, do this: include ActionController::UrlWriter default_url_options[:host] = ‘whatever’ Then you can call your named route methods directly from the console.
I am happy to report that AltLaw.org‘s switch to Solr has worked very well. Solr is a RESTful search engine, built on Lucene. The setup was more complicated than just using a search library, but the rewards were worth it. Before, I was using Ferret, which I still like. It’s a great library, and Dave…
Dan Weinreb posted common Complaints About Common Lisp. My personal complaint is in there — the lack of libraries that are well-documented and regularly updated. I think it’s a critical mass problem: so few people are using Common Lisp in their day-to-day work that there’s not enough momentum to keep the libraries going and make…
Larry Wall writes about scripting, “I can’t define it, but I’ll know it when I see it.” So I thought I’d throw out my idea of a definition. A scripting language is a programming language that relies on and is designed to run within an ecosystem based on other languages. So Perl 5 and Ruby…
A couple nights ago I walked down to LispNYC in the East Village to hear Rich Hickey talk about Clojure, his new Lisp-like language. To be honest, I wasn’t expecting much. Another Lisp? Ho hum. I’m sure it’s very clever and cool and all, but not something I can actually use. Instead, I was blown…
