Don’t Smash That SD Card!

Stop! Wait! I know what you’re thinking. This SD card has more the 50MB on it, but Windows won’t format it properly. Even Disk Management is failing.

For anyone who backs up their Raspberry Pi images or re-images their SD cards, this can be a huge hassle. Let alone if that unfortunate moment has come and your SD card or USB stick is showing no memory available at all. The formatting is just ruined. Breathe deep there are utilities out there to help.

Fedora 24+ Remote Desktop (VNC)

One issue I’ve found written about on forums (without resolution) and experienced with much frustration is getting remote desktop via VNC to work on Fedora 24 server and newer. It seems like something has changed in the matrix and running the standard setup for vnc server on Fedora that worked on Fedora 19/20/21/22/23.. just doesn’t seem to work. Now as curious as I am, I’m not going to go install a VM of any of those versions of Fedora and track down the minutia of differences. What I will describe though is how to get it to work.

If you’ve been trying this and can’t seem to get it to work, the problem may lie on the TigerVNC viewer for Windows. For me the Windows VNC client keeps connecting properly but the screen is always blank. I noticed the vncserver instances that I started on my Fedora server were all 24 bit and the Windows TigerVNC viewer kept “connecting” to 32 bit sessions. What did work for me was switching to RealVNC viewer, the connection worked perfectly on my local server.

The step by step instructions are as follows:

Rock Paper Scissors in Ruby

Recently I’ve been working on developing my Ruby programming skills, simply due to the lots of great opportunities to use it on Linux servers. I’ve been reviewing both the evergreen “Learn Ruby the Hardway” and “The Well-Grounded Rubyist” by: David A. Black which both have ¬†proven to be extremely useful. The LRTHW online platform serves as a great review/introduction while The Well-Grounded Rubyist goes into some nitty gritty details.¬†As an aside, my membership the the ACM (Association of Computer Machinery) has been vital because it gives me access to both the Safari Books library and the Skillsoft library. A lot of books on endless technical topics, too bad studying couldn’t be your day job.

So at last to make some of this knowledge “my own” so-to-speak I’ve developed a basic command line version of “Rocks Paper Scissors”

It can currently be found on my GitHub page: https://github.com/StampedePress/RoPaSc
