dougalcampbell / wxrsplit.pl
Created Mar 1, 2016
A perl script to split WordPress WXR export files into multiple, smaller files
View wxrsplit.pl
#!/usr/bin/perl -w
#
# wxrsplit - Split a WordPress WXR file into multiple output files, each
# with a maximum filesize.
#
# NOTE: Because this tool attempts to keep items intact within each output
# file, it is possible to exceed the specified max filesize. Comments are
# contained within a post item, so a post with many comments could
# conceivably generate a very large item size. There probably is not a
# practical way around this.

without the need to escape quotes or end-of-line
characters.

Example of driving an Adafruit NeoPixel Ring with the Digispark Arduino-compatible board
View NeoPixelTest.ino
#include <Adafruit_NeoPixel.h>
#define PIN 1
#define STRIPSIZE 16
// Parameter 1 = number of pixels in strip
// Parameter 2 = pin number (most are valid)
// Parameter 3 = pixel type flags, add together as needed:
// NEO_KHZ800 800 KHz bitstream (most NeoPixel products w/WS2812 LEDs)
// NEO_KHZ400 400 KHz (classic 'v1' (not v2) FLORA pixels, WS2811 drivers)

Digispark and nodejs - talking to the Digispark Arduino-compatible microcontroller via USB with the node-hid library
View ds-duino.ino
/*
* Accept control commands via USB.
*
* Commands start with '!' and end with '.'
* Commands have three parts: action, pin, value: !AAPPVV.
*
* E.g. '!01p101.' is DigitalWrite, Pin1, value = 1
*
* Note: This is currently *very* crude. Much improvement could be made.
* I think the use of strncpy is eating a lot of memory. Refactor?

dougalcampbell / hsl2rgb
Last active Dec 22, 2015
For future reference... The W3C-suggested algorithm for converting HSL color to RGB. In the funky ABC pseudo-code. http://www.w3.org/TR/2011/REC-css3-color-20110607/#hsl-color
View hsl2rgb
HOW TO RETURN hsl.to.rgb(h, s, l):
SELECT:
l<=0.5: PUT l*(s+1) IN m2
ELSE: PUT l+s-l*s IN m2
PUT l*2-m2 IN m1
PUT hue.to.rgb(m1, m2, h+1/3) IN r
PUT hue.to.rgb(m1, m2, h ) IN g
PUT hue.to.rgb(m1, m2, h-1/3) IN b
RETURN (r, g, b)
You can’t perform that action at this time.
