When you create a project in MPLABX, quite a few files are created within the project folder. After some trial and error testing, I found that the only files really necessary for MPLABX to open a project are these:
<ProjectName>.X (this is the project folder)
<ProjectName>.X\Makefile
<ProjectName>.X\nbproject\configurations.xml
<ProjectName>.X\nbproject\project.xml
 
Items to ignore would be these:
# MPLABX folders
build
disassembly
dist
private
# MPLABX files
funclist
project.properties
Package*.bash
Makefile*.mk
Makefile*.properties
 
(MPLABX is based on Netbeans version 6, so I imagine Netbeans projects may have similar file sets. I'm not familiar with other types of Netbeans projects, so I'm just guessing here.)
 

Converting version control repositories from Bazaar to Git (bzr to git)

Bazaar is great on Windows. Several years later, git's tools for Windows still.... (ahem) are lacking or too commercial. However, official development on it has ended and git is so much more popular now. So I think the time has come to convert all my beloved bzr repositories to git.

First we need note some prerequisites:

Adding a hardware clock to Raspberry Pi (DS3231)

The popular clock module is uses the DS1307 real time clock chip, which is not very precise. For just a few dollars more, you can get a module with a much more precise DS3231 RTC chip. The one I got was SunFounder's module from Amazon for $9 (free shipping for Prime). It plugs right onto the Raspberry Pi's 40 pin header and doesn't even interfere with the plastic case I have. I have a Model B, but this module should also work on Model A and Model B+. The instructions refer to DS1307, but the chips use the same I2C commands, so it also works for DS3231.

How to run a PiPresents show when you don't have a Raspberry Pi

PiPresents is some pretty cool software that will run a PowerPoint-like presentation. But with lots more flexibility. It was originally written for the Raspberry Pi.

However.... perhaps someone else has your Pi. Perhaps you don't even have one. It is possible to run a PiPresents show on  your good ol' desktop computer (Windows, Linux, or Mac). Here's how.
