Learn RegEx Interactively

Lauren Coates of LSU’s Digital Scholar’s Lab sent along a link to Regexr, which allows you to teach yourself regex interactively. I’ve seen other sites that do this, but Regexr has a great UI. Time to go test some regex problems I’ve had lately to see if I can’t figure them out…

I saw a post recently over on DataScience+ about the use of a Python library, bokeh, for creating interactive graphs. My first thought: You can do interactive plots in Python?

PDF Index Generator

PDF Index Generator is a powerful indexing utility for generating the back of your book index and writing it to your book in (4) easy steps. PDF Index Generator parses your PDF, collects the index words and their location in the PDF, then writes the generated index to a PDF or a text file you specify. The main target for PDF Index Generator is to automate the process of generating the book index instead of doing the hard work manually.

I didn’t get to try this out, but I had it bookmarked. (UPM was very kind to do the indexing for me since the moment it needed to be done was also the moment that my father died.)

Geo-centrism vs Heliocentrism

Sometimes it’s hard to explain the notion of simplicity in science as a principle for explaining things. Then someone sends you a link, and you have a visualization of the difference between trying to explain the solar system being geocentric, very complicated, and the solar system being heliocentric, very simple.

Simpler URLs

Occasionally I think about simplifying the URLs for jl.o because I find that the date as an 8-number preface is cumbersome, but I worry about losing readers and links that have come to depend on a number of posts. It turns out there is WordPress plug-in that can manage this process, as [Tom Ewer notes on WPExplorer][]: “To easily create the redirects on your WordPress website I recommend the [Simple 301 Redirects][] plugin.”

Ewer also offers the following bit of advice for after you have made the change: “You may still have the odd broken link 404 error, so it may be worth thinking about creating a custom 404 page with information about the permalink change. That topic is for a whole other post though.”
