After many years as a professional software developer, I finally felt the urge to pursue one of the many certifications out there. Since I really like using MongoDB lately, and I aced all the MongoDB University online courses I’ve taken, it made sense to take the Certified Developer exam.
Changing the primary domain name on a Google Apps account is a non-trivial process. I recently needed to do this for a customer, and created a console application that makes the job easier.
This works on OS X and Linux; Windows support is unknown (and will not be tested by me). It’s written in Go, so you will need to have a Go development environment set up to build or run it.

Installing collectd with the usual command on an Ubuntu 14.04 server:
sudo apt-get install collectd
results in a ton of packages being installed:

Most likely this is overkill. To install with minimal dependencies:
sudo apt-get --no-install-recommends install collectd
which results far fewer dependency packages being installed:
collectd collectd-core fontconfig fontconfig-config fonts-dejavu-core libcairo2 libdatrie1 libdbi1 libfontconfig1 libgraphite2-3 libharfbuzz0b libltdl7 libpango-1.0-0 libpangocairo-1.0-0 libpangoft2-1.0-0 libpixman-1-0 librrd4 libthai-data libthai0 libxcb-render0 libxcb-shm0 libxrender1
Much better.
Bonus: Saltstack state example:
Install collectd:
pkg.installed:
- name: collectd
- install_recommends: False
Sites that sell lossless usually offer only FLAC files. To convert to ALAC for iTunes and iDevices using ffmpeg:
for f in `ls *.flac`; do ffmpeg -i $f -c alac ${f/flac/m4a}; done
This assumes the current directory is the directory containing the FLAC files.

My 19 month old daughter loves to watch videos on my iPhone. She knows right where to go in the Photos app — either in the Camera Roll folder to watch videos we might have recently captured, or in the “Videos” folder containing videos from the computer. Content in the Videos folder is safe from deletion, but not content in the Camera Roll. Occasionally she gets to tapping on the screen and starts the process of sending a video to someone via email (inevitably to someone in my contact list that I haven’t contacted in years), or accidentally deleting a video. More than once she has deleted a video I wished to keep.
I’ve seen “undelete” iPhone apps on the web, but no free ones. In my case, I frequently charge/sync my iPhone with my computer, but only occasionally download the Camera Roll photos and videos to an image or video editor. Figuring the video must be on my computer as part of a recent iPhone backup. I went looking for them. Continue reading Recovering Videos Deleted from iPhone
