I had recently had a Mac on Lion unable to load the Users & Groups Preference Pane. Like this: My IT support had suggested reimaging the computer. Reinstalling the Operating System, reloading the applications, and transferring back the User information from Time Machine Backup. Well, after doing all of that, the problem reappeared immediately. I scoured through Apple Support Communities and found this fix. For some reason, some transparent users are showing up in your system. They need to be deleted. But since you cannot load Users & Groups... it becomes a problem. Here is the solution / procedure. Quit System Preferences. Launch Terminal. (Applications/Utilities/Terminal) Copy & Paste these commands. sudo dscl . delete /Users/Guest press enter Terminal may ask for your Administrator Password, enter that. sudo dscl . delete /Users/Guest1 press enter Terminal may ask for your Administrator Password, enter that.

As I prepare for coaching Middle Schoolers here in Waupaca for FIRST Lego League, I am trying to teach kids to code the SPIKE Prime Lego robots. This has its challenges. Some kids take to coding well, and some need more visuals to guide them. Teams may also want to whiteboard out their coding concepts. I created this set of printable Word Blocks as a resource for printing, laminating, and maybe adding some magnets to the back. This allows me to put up code in a demonstration, or my teams to talk about how to achieve things after they have done some pseudo-coding of their projects. Having manipulative items are always nice for hands-on coding practice. Whiteboard Word blocks for Proportional Line follow. Here is my collection of laminated word blocks Below are the files I created for creating these blocks. Feel free to use, but maybe send me a note & follow on twitter. @artschultz13 Direct link to folder shown below.
Link to my website... I have been away from my blog for a long time... It’s been a while since creating my last blog post. It’s about time to get back on the horse. Creating QR Codes. Super simple tool for getting links and information out to people in a passive way. Got a concert? Why print off a program when you can have people grab a link from the qr code and look at it on their phones. Making stations for your classroom? Why not make the instructions for the station as a QR code... I like goqr.me as a generator for other items such as contacts and email links. This video below shows how to use chrome and goqr.me to make QR codes on a desktop computer. #artschultzblog #edtech #qrcodes via IFTTT
