Installing darkstat per instructions from tecmint.com , I encountered a small hiccup. After the complete instructions, I need to run “darkstat -i wlan0” to start the service. The init.cfg configuration didn’t seem to be enough.

cluster maps using map box
https://jsfiddle.net/5ju06dp1/ is a link showing how to do a cluster map. It’s based on https://docs.mapbox.com/mapbox-gl-js/example/cluster/ . Putting it up since I may be coding using the sample.

Ctrl C loads the page
I encounter a problem where node js or the webpage appears to be hung. I never thought that the shell could be the problem. This problem happens randomly. After some googling, I found the answer at
https://github.com/nodejs/node-v0.x-archive/issues/8196
Simply uncheck “Quick edit mode” in the shell.

npm error during installation
I frequently encountered a error message similar to below

All I had to do was up the version, in this case express-handlebars to at least version 1 instead of 0.5

I successfully run git clone from the command line prompt. However, faced many problems using cygwin. Noting this down for future reference.

I had to update

to turn on HTTP_GET_VARS
