Open Codex HISTORICAL entry

2012 May 01 | DOI metadata and change_case

With Zotero and Mendeley providing excellent web-centric bibliographic tools, I don’t imagine I’ll ever get converts to Thunderdell. Still, it and BusySponge are integral to how I work and I enjoy the occasional Python programming. Some disjointed thoughts from the bibliographic screen-scraping front.

(I’ve been meaning to post an update on Thunderdell and an interesting conversation with Nathan Matias about his work prompted me to do so.)

2011 Feb 10 | MW: a command line interface to MediaWiki

The MediaWiki experience can be as frustrating to a hacker as it is for a newbie. Editing on the Web page is annoying and the syntax is atrocious. For myself, I prefer using Markdown syntax, a good text editor, pandoc, and a distributed version control system (VCS). (That's how I wrote my book.)

I, and others, crave a similar toolset for editing MediaWikis. I tried WikipediaFS once, but looking at a versioned wiki as a simple filesystem didn't do the trick and the project is unmaintained. The mvs Mediawiki client comes with Ubuntu, but I could never get it to work. wikish is OK but doesn't do all that I would like.

Recently, I stumbled upon Ian Weller's mw, "VCS-like nonsense for MediaWiki websites". He provides a great foundation and the basic pull, diff, commit and status commands. Since it's written in Python, I could actually grok it, extend pull so it can pull new updates and warn of conflicts, and provide simple merge functionality.

You can see examples of the pull, conflict, and merge functionality in a short MW tutorial I drafted.

2010 Nov 24 | Smoother recording on VirtualBox

For a number of years now I've been using NaturallySpeaking speech recognition via a virtualized Windows environment on Ubuntu. Speech recognition gurus will recommend using an external USB sound card so as to avoid any electrical interference common with soundcards within the computer case. This is fine for the most part, except that VirtualBox's performance with USB sound devices can be a little choppy unless one uses a low-latency (i.e., real-time) kernel. However, Ubuntu only seems to release such kernels every other release.

Luckily, I recently discovered that one can use USB microphones within VirtualBox as emulated hardware devices -- by making use of the VBOX_ALSA_DAC_DEV and VBOX_ALSA_ADC_DEV environmental variables. That is, instead of letting VirtualBox see the microphone as a USB device, you let Linux keep hold of it as a USB device, and it offers an emulated sound card to VirtualBox. This seems to avoid any audio problems in recording/playback, and means I am no longer dependent upon non-generic kernels.

I have posted a small Python script that sets these variables given a particular USB microphone that you want to use, and also sets the microphone volume level, since that is often set at zero in the Linux context.

2010 May 17 | Sentence Case in Bibliography

As a PhD student, one of the first bibliographic annoyances I encountered was when I had to format a paper using the APA system, which requires titles to be in sentence-case. This means only the first word of a phrase and proper nouns are capitalized. Previously, I had kept the titles of my citations in title-case. The consequence of having to use the APA format was the need to then go in and manually lower case all words that were not proper-nouns in my bibliographic database. However, once this work was done, I realized keeping my data in sentence-case was preferable, as title-case essentially loses information. Yet, this still requires me to manually lowercase some words for automatically captured sources. I am not aware of any bibliographic software that handles this issue well, and the good folks at Zotero have an interesting bug ticket open on the issue.

On Friday, while I was doing my weekly fixes to the automatically captured sources in my field notes/mindmap/bibliography, I thought to myself that there are plenty of word lists around, such as those used by spellcheckers, and couldn't I finally automate this menial task? However, I knew that I use lots of proper nouns that probably do not appear in common dictionaries. Therefore, I applied Python's Natural Language Toolkit tokenizer and parts of speech tagger to the text of my dissertation to create a custom word list of proper-nouns that I use. These are used with the dictionary found on my system at /usr/share/dict/american-english to transform a title-cased sentence into a sentence-cased sentence. Basically, if the word is in my custom list, is in the word list only as a capitalized word, or not in the word list at all, it merits capitalization, else lower-case it. The code is available as a module to the Busy Sponge component of the Thunderdell bibliographic tools. It works fairly well and will certainly make that end of the week menial task all the more easier.

2010 Apr 06 | Indexing a Book

One of the last significant steps for an author is to compile an index, unless they opt to have someone else do it. Publishers often recommend authors create the index as they know the material best. However, while professionals have sophisticated -- but proprietary -- tools to help them, authors are offered only the techniques of using index cards or spreadsheets. Neither of these options is appealing to me.

I thought it would be nice to simply compile a list of entries in the form of topic (page#|see) (sub)topic and let a script do the rest. It's a bit of a hack but it does the job and can collapse all subentries below a particular threshold. I like having specified subentries, even if there is only one or two of them for a particular entry:

Apology
    and leadership, 124
    "Sorry but...," 54

But if the publisher says they want those collapsed, it is easy enough:

Apology, 54, 124

2010 Feb 16 | Diffing Word Files

For the most part, I wrote my dissertation and book manuscript using a simplified version of markdown complemented with biblatex citations. Because it was a simple text file, it made managing the edits to the manuscript very easy. I could do global textual replacements trivially. Also, obviously, it was trivial to generate PDFs, HTML, etc. Using Mercurial, I could take advantage of some nice features like the "attic" extension which allows me to keep change sets on the side to be applied only when appropriate. So, for example, the changes necessary generate HTML were kept in the attic and would only be applied when I wanted that.

Unfortunately, once the manuscript went into the MIT Press system, I had to use Microsoft Word. As much as much as the Word document format annoys me, I understand it is widely used, and I can't think of an easy alternative that also provides the capability for editorial annotations. Nonetheless, I had a difficult time seeing changes in Microsoft Word, and want to backport the changes into my source files. And, there does not appear to be a nice textual difference tool for Word documents.

I have posted a small Python script that makes use of antiword and dwdiff but also gives me context on either side of the change. It, of course, doesn't work well with formatting, but is useful and will generate output like the following:

   reflects {-the-} [+a+] stabilization

     [+project was conceived. It+] would

2010 Jan 12 | Thunderdell v1.2

I have tagged a new release of Thunderdell, the Freemind mindmap to biblatex utilities. Improvements include:

2009 Aug 21 | Shared Clipboard and Chicago Page Ranges

I use VirtualBox to run a Windows guest, and unfortunately the shared clipboard between the two is sometimes buggy. I recently posted a script for a very robust clipboard using a network shared file. Also, I'm doing the final checks on the book manuscript and the Chicago Manual of Style has odd and confusing rules for specifying ranges of page numbers. The CMS page range validator looks through my sources files and prints out any likely to be counter to Chicago style.

2009 Mar 13 | BusySponge 0.5

In 2002 I began thinking about how to best capture and share the many web-pages and small tasks of the day. I thought of it as a "busy sponge": logging bookmarks and tasks to my team page with a minimum of typing. Furthermore, I wanted to tag each entry with a keyword which could then be used in queries. I posted an implementation in 2003 which was complemented by the fact that the tasks on my team page were syndicated (via RSS) -- and used to generate my "two minute reports" at the weekly staff meeting at MIT. This was a number of years before the notion of micro-blogging became popular.

Two interesting features have further matured: I wanted it to fetch the title of a URL -- typing HTML was a hassle -- and I wanted to tell it which of my pages to log the entry to: my personal weblog or work team page. For example:

urd:/home/reagle > b http://pesto.redgecko.org/dispatch.html j python Noted ^

is a sponge of a URL to my "j" (work) page where "^" becomes the hypertextual page title, resulting in:

<li class="event" id="e090313-f7fd">090313: python] <a href="http://pesto.redgecko.org/dispatch.html">Noted URL dispatch &mdash; Pesto: a library for WSGI applications</a></li>

With BusySponge 0.5 (now distributed as part of Thunderdell), this has matured into a set of classes for webpage screen scraping and a set of logger functions. So, for example, I might sponge a comment about a URL and indicate it should log it to my bibliographic mindmap (Thunderdell) and it will do its best to fetch the page author, title, date, publisher, permanent link, excerpt of first substantive paragraph, etc. The default heuristics do a surprisingly decent job -- certainly better than typing it from scratch -- and the specific scrapers (e.g., Wikipedia, MARC email archives) are quite good.

2009 Jan 22 | Thunderdell 1.0 (was: 'FreeMind Extract')

I'm releasing the latest set of Freemind Bibliographic Extraction scripts. I'm calling it a "1.0" release because:

  1. I decided to give it a funny name.
  2. I now address an unlikely but long-time screw case.
  3. This and other cases are now tested by doc_tests.
  4. I updated the generation of bibliographic keys to remove 'and' from the author portion and always include a title suffix -- instead of just when there is a collision. Keys are now a bit more terse and more stable.
  5. I now emit biblatex, a much more complete and powerful bibliographic format.

It also now has its own webpage, from which you can download it.
