useful tools

Mondays are my days for finding useful but mundane tools.  Today's useful tool is xpdf.  Why is it useful?  I want to compare two pdf documents, and that is much easier to do when they are not pdf documents.  Happily, xpdf has in its repertoire a script for converting pdf files to text.  It is even klutz-compatible because (A) it works in Windows and (B) it only needs minimum command line attention.  And there are instructions!  If you feel like you are spending too much time on crummy manual tasks, this is one of those good tools to have handy.

Today I used xpdf for mysterious purposes that I am barred from disclosing.  Tomorrow, I am going to use it to compare two insurance policies.  Most "insurance people" are the non-technical types, so they read whole policies and hope to notice the differences between them.  I am quite adept at this in fact, but I usually delegate to someone who is not yet up to speed on things like marketing, producing, or shouting at underwriters.  So many insurance policies are available in texty pdf format these days that it seems silly not to compare two policies electronically.  Most agencies use human labor for this purpose.  Welcome to the information age!

If all you want to do is see the differences between your two text documents (as opposed to writing a script to update another file based on the differences between two files, which is my real ambition… but for another day), you might want to try something like WinMerge. One nice thing is that it is open-source, so if you are smarter than I am, you can probably use it to do exactly what you want.  But if you need klutz-compatible software, you can use it as-is and see exactly what changed between two versions of a text file!  Oh happy day!

Note: Texty pdf files are distinguished by the fact that they were converted to pdf from a format containing text, as opposed to images of text.  There is probably a real word for this; unfortunately, I had to make up my own word, so please deal with it.

    • Modo Vernant Omnia - Tampa local with many topics of interest to my readers. As you might imagine, I could not resist blogrolling a site that has tags as diverse as: economy (with views similar), spinning (as in wool), ancient Greek stuff, and occult.
    • Nassim Nicholas Taleb - Fooled by Randomness - The Economist turned me on to Mr. Taleb, a trader turned philoisopher (as described by Forbes). His writing and his thinking are quite interesting, and certainly more worthwhile than anything you will find here.
    • Ouralexander.org - Site discussing informed consent in pediatric medicine, by a family that experienced the worst possible tragedy.
    • RiskProf - An Insurance Blog - A truly marvelous blog. I know risk & insurance are less interesting to most of you than organizing your sock drawer, but this is excellent writing. Besides, if you understand insurance you have the right to complain about it.
    • Schneier on Security - This will be your favorite security blog. Bruce Schneier exposes “security theatre” and proposes realistic problems and solutions. Stay up to date on security policy and IT risk management with CRYPTOGRAM, his email newsletter.
    • The Goodly Mr. Plotkin - My excellent friend Richard Plotkin. Read his musings and insights, or wander through the social network of MySpace users. Several of his blog-friends are people I went to school or knew other ways… I wonder if they will Google me and say ‘hi.’
    • Worlds Healthiest Foods - I love this website. It is all about the nutritional value of foods that are considered ‘healthy,’ with tons of sources cited.
