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.

Capitalize first letter of each word in a string - A ruby alternative

Don't spam root. Log your cronjob output to syslog

This command will log the output of your simple cronjobs to syslog, and syslog will take it from there. Works great for monitoring scripts which only produce simple output. Advantages: * This can be used by regular users, without modifying system files like /etc/syslog.conf * Reduce cron spam to root@localhost (Please stop spaming the sysadmins) * Uses common tools like syslog (and logrotate) so that you don't need to maintain yet another krufty logfile. * Still ensures that the output is logged somewhere, for posterity. Perhaps it's stored the secure, central syslog server, for example. * Seems to work fine on Ubuntu, CentOS, FreeBSD & MacOSX
