So I ran into a few issues using the dd image backup I referenced prior Raspberry Pi 3 SDCard backup The Image is very large even though the data was not. For example on a 32GB SD card I was getting a 12GB file. I only have 3GB of data! so that was a bummer. When it comes time to recover, I have to expand the gz image file to a full 32GB to then image it onto another SD device. There’s tricks around this I’m sure but still. Since dd was reading 100% of the SD card (/dev/mmcblk0) even with compression it took a LONG time to create the image. 20 minutes or so. Since I’m backing up a live system this was a real issue. I did manage to figure out how to create a partial image if your partition sizes were smaller than the actual device - This seemed to work but it still was storing 6.6GB of data which was over double what I actually had: ...

From https://www.raspberrypi.org/forums/viewtopic.php?f=63&t=77492 dd if=/dev/mmcblk0 | gzip > /media/usb/mmcblk0.img.gz Checking if this works. More to come :)

Ah good times… Below is from 2010! Here’s some new details on snipes… https://www.vogons.org/viewtopic.php?t=49073 I have 4 VM’s running MS-DOS and Netware. Game On! Instructions: Use a vnc viewer like TightVNC (realVNC didn’t work for me, only gave me a blank screen). Go to one of the following server wijgalt.homeip.net Connect to one of the ports, 5901 thought 5904 If you already see activity on the screen, just exit and try another port. Go to drive G: Run nlsnipes If there’s a game already going it will tell you. Just wait a bit and try again! Enjoy!

Unlike most apps that will provide a proxy web service to your computer through your iPhone PDAnet will provide a complete network solution for tethering your computer. Basically, you can use your iPhone as a computer wifi device, without restriction. While proxy apps will work well for web applications, it doesn’t work for stuff like email, ftp, ssh, etc. PDAnet can handle all network traffic. I’m using my iPhone right now to access the internet from my Macbook Pro and it’s quite fast! Check PDAnet out! http://lifehacker.com/5086490/the-best-way-to-tether-your-iphone-to-your-laptop-for-free

While the newer versions of OS X have been great and the dock has matured, I hated one thing. Sometimes I just want to put a directory on the dock without it doing it’s crazy effect stuff to it like Fan, Grid, List, etc. Many times all I want is a dock icon that will just open a directory in finder. Fortunately, I figured out how to do this!!! Create a link to the directory of your choice on the desktop. For instance, I created a link (By holding down the “option”, “apple/command” keys down) of my home directory on my desktop. Now, drag that link to the dock. Bingo! I have a dock icon that will just open a finder window of my home directory.

This is a great project for just about anyone who ever went to class with a TI calculator. With a few lines of code on the calculator and a 2.5mm male to male plug you can create time lapse photos.

I just started using su.pr to shorten long urls and it has the ability to do some very cool stuff if you link it into your wordpress site. I prefer it over tunyurl and others. Check it out!

If you go to http://dsstos.blogspot.com/ there’s an excellent presentation on data storage concepts and recommendations. It’s HDS AMS focused, but the majority of the presentation relates to general data storage. Great stuff!

For OS X Leopard this worked for me. Cut and paste this command into terminal: /System/Library/Frameworks/CoreServices.f*/Frameworks/LaunchS*/Support/lsregister \ -kill -r -domain local -domain system -domain user
