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.

Teaching tricks. I have a loveable little dog. Her name is Molly. It takes her a bit to get something, but once she gets it... she knows it. She doesn't do tricks, but she sits and stays. She is a good dog. I get a treat after this, right? Well, as a Technology Integrator, I have been trying to find ways to teach my teachers 'computer tricks'. I am new to my school this year, but I feel like I am getting there. Winter is nearly over, so new doesn't cut it anymore. The schedule at my school is a bit difficult to meet with many groups on a regular basis, and my teachers are busy. And asking them to attend a training is difficult. So, I started using YouTube LIVE. I have been planning Professional Development sessions, and broadcasting a live version on Tuesday afternoons, which I have been calling 'Tech Tuesdays in the 803'. I use a Google Site to promote, send the link to the live stream, and send the teaching session materials. I archive
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.
