• Inkscape Tutorial: Vector Image Trace

  I'm always on the lookout for new tricks to use in any of the graphics programs I use. I saw this one on YouTube in a video by Logos By Nick. While you may have already learned this little maneuver, it was a bit new to me. It takes a bit of practice, at least for me.

  This method works well on a photo you want to trace. Maybe you are creating an advertisement and you have a photo of what you want, but you need clipart instead. You can always do a trace of the photo to use. We'll be using the Bezier tool.

Make sure you bring in a bigger copy of your photo if possible (because images can be scaled smaller without quality loss, but not bigger). After you have it imported, add a layer to your project. You'll do your work on the new layer. In celebration of Linux's birthday this month, I'll use a photo of a penguin.

• How to Use atop to View Active Processes on Linux

  If you use Linux, you likely use programs like top or htop to monitor your processes. A lot of these processes may not be relevant to you. What if there was a tool that only showed active processes? There is, and it's called atop.
