OpenS3 is basically a storage server. What it does is provide a JSON API to upload and download files to a specified path. It includes a bucket feature to organize uploads.

Details!

Uses Thin as HTTP server and rack for interacting with it. For uploading, listing and downloading files you'll need a token, which is a SHA512 of a string you choose. You'll also need to set an expiry time for a link when downloading.

Docsplit is a command-line utility and Ruby library for splitting apart documents into their component parts: searchable UTF-8 plain text via OCR if necessary, page images or thumbnails in any format, PDFs, single pages, and document metadata (title, author, number of pages...)

Docsplit is currently at version 0.5.0.

Docsplit is an open-source component of DocumentCloud.

Usage

The Docsplit gem includes both the docsplit command-line utility as well as a Ruby API. The available commands and options are identical in both.
--output or -o can be passed to any command in order to store the generated files in a directory of your choosing.

images--size --format --pages Ruby: extract_images
Generates an image for each page in the document at the specified resolution and format. Pass --pages or -p to choose the specific pages to image. Passing
--size or -s will specify the desired image resolution, and --format or -f will select the format of the final images.

docsplit images example.pdf
docsplit images docs/*.pdf --size 700x,50x50 --format gif --pages 3,10-15,42
Docsplit.extract_images('example.doc', :size => '1000x', :format => [:png, :jpg])
text--pages --ocr --no-ocr --no-clean Ruby: extract_text
Extract the complete UTF-8-encoded plain text of a document to a single file. If you'd like to extract the text for each page separately, pass --pages all. You can use the --ocr and --no-ocr flags to force OCR, or disable it, respectively. By default (if Tesseract is installed) Docsplit will OCR the text of each page for which it fails to extract text directly from the document. Docsplit will also attempt to clean up garbage characters in the OCR'd text — to disable this, pass the --no-clean flag.

docsplit text path/to/doc.pdf --pages all
docs = Dir['storage/originals/*.doc']
Docsplit.extract_text(docs, :ocr => false, :output => 'storage/text')
pages--pages Ruby: extract_pages
Burst apart a document into single-page PDFs. Use --pages to specify the individual pages (or ranges of pages) you'd like to generate.

docsplit pages path/to/doc.pdf --pages 1-10
Docsplit.extract_pages('path/to/presentation.ppt')
Docsplit.extract_pages('doc.pdf', :pages => 1..10)
pdf Ruby: extract_pdf
Convert documents into PDFs. Any type of document that OpenOffice can read may be converted. These include the Microsoft Office formats: doc, docx, ppt, xls and so on, as well as html, odf, rtf, swf, svg, and wpd. The first time that you convert a new file type, OpenOffice will lazy-load the code that processes it — subsequent conversions will be much faster.

docsplit pdf documentation/*.html
Docsplit.extract_pdf('expense_report.xls')
author, date, creator, keywords, producer, subject, title, length
Ruby: extract_...
Retrieve a piece of metadata about the document. The docsplit utility will print to stdout, the Ruby API will return the value.

docsplit title path/to/stooges.pdf
=> Disorder in the Court
Docsplit.extract_length('path/to/stooges.pdf')
=> 36

If you’re developing with Rails you’ve probably encountered rake once or twice. This blog post aims to walk you through where rake came from and an introduction on how to use it effectively in your Rails apps.

A Little Bit of History
Rake is the project of Jim Weirich. It’s a build tool. For a good laugh and an even more in depth history check out the "rational.rdoc" from the Rake documentation. Essentially, rake started as an idea for using Ruby inside of a Makefile. Though Jim doesn’t sound convinced from the tone in that document, it is a good idea.

Plist is a library to manipulate Property List files, also known as plists. It can parse plist files into native Ruby data structures as dwell as generating new plist files from your Ruby objects.

Those TextMate powerusers out there are likely familiar with the sheer awesomeness of the Bundle facility. No doubt you’re also aware that you can live on the edge by checking bundles out from subversion.

The problem is, there are a TON of bundles, and I simply don’t care about the majority of them. Having a ton of bundles slows down the application launch and makes the Bundles menu unwieldy. The obvious solution is to only check out those bundles you are interested in… but when that list is close to 50 items long, it gets tedious.

So what’s a hacker to do? Write a script? You bet your boots. In an effort to keep the size of this entry down, I’ve put the script on a separate page, located here.

To use it, edit the bundles array to include the list of bundles you want to keep up-to-date. Put the script in your path, chmod +x it, and run it. If your Bundles directory doesn’t exist, it’ll create it for you. If it sees a bundle it doesn’t know about, it’ll ask you whether you want to delete it. This brings us to a neat thing I discovered. Try this in irb:




puts "whoa!" if gets =~ /^(n|$)/i

I was trying to allow the user to just enter to accept the default (no) answer when it asks if you want to delete. I wasn’t expecting the regex above to actually work, but it does… essentially, if the first character of the line is either ‘n’ or the end of the line, it’s true. Cool, yeah?

Please, go check it out, and use it if it makes your life easier. I’ll gladly take suggestions and improvements as well!

Introduction to using vim for Rails development

Someone recently asked us to do “vim on Rails” screencasts.

So, we’re responding with this experiment. Let us know if this is valuable and we’ll try to improve things like audio quality.

Cinderella is a fully managed development environment for open source hacking on Mac OSX. It's powered by rvm, homebrew and chef. You only need Xcode to get started.

Cinderella builds everything up in ~/Developer. It won't stomp on any of your current installations so you don't have to commit your entire machine immediately. It's simple to rollback if you really want to.

I'm trying to amass a list of programming books with opensource licenses, like Creative Commons, GPL, etc. The books can be about a particular programming language or about computers in general.
