Powershell Curl Logs Signal Strength of Cable Modem

IMPORTANT: You need Windows PowerShell to run this command - in your Windows Command Prompt, type powershell Create a log file of your Motorola Surfboard SB6141 downstream signal strengths. Uses the built-in curl to request signal strength data from your SB6141 cable modem. HTML page 192.168.100.1/cmSignalData.htm has the signal strength numbers for the 8 downstreams. Some HTML/DOM processing parses out the 8 values from the above page. The eight extracted signal strengths are then logged to a file. A small while-loop watches the clock & repeats the process every 10 seconds. Show Sample Output

Auto-kill auto-spawned process

Given a process name (kdiff3 in this example) that keeps auto-spawning/starting, auto-kill until it stops, assuming there is an upper limit (if not, reboot). This was beneficial after I clicked the DIFF button in a git GUI on a merge commit. 2000+ files were being opened one after the other in my diff program (kdiff3). Each time I closed one (or quit Kdiff3), the next file would be auto-opened in Kdiff3.
