Old Skool
looks like people are rediscovering the beauty of pure vector graphics, and even taking it to the next level.
Here is a great blog post with a collection of YouTube videos of some great oscilloscope demos.
My favorite is the last one. I love that kind of visualiztion.
Chris saves me hours… yet again
Chris pushes out a great post on how to get helpers working in the rails console. This and ‘rake routes’ are just fantastic timesavers.
(note to self: good link to the RAILS REST routes, stuff here)
A simple-directory printer: Part 2
Today I saw a posting asking “what does this command do?”
ls -R | grep “:$” | sed -e ’s/:$//’ -e ’s/[^-][^\/]*\//–/g’ -e ’s/^/ /’ -e ’s/-/|/’
Hint: it is related to my post which is now part 1.
I have to say, this clever use of 30 year old tools is just excellent. command line version using sed is just super clever. Very cool.
Nice free PDF tool
If you need to create PDF files in windows, I highly recommend PDF Creator.
This tool is free and open source (no up-sells, or crippled features). It basically allows you to print to a PDF (something that is already built-in if you use Mac OS X).
