apache httpd for android phone 2018-11-05 19:56 UTC
Today, I installed apache httpd web server on my phone.
In the google play store, search for http server.
After installation, the index.html file was visible to the world. No settings needed.
You need to know your phone's IP. My phone uses an IPv6 address. The format for IPv6 addresses to put in your web browser is: http://[2700:xxx....]:8000/ with 8000 being the optional port. The open and close square brackets seems necessary for IPv6 addresses.

How to Read a Screw or bolt Thread Callout 2018-07-30 14:24 UTC
I find this wikihow on how to read screw/bolt thread code very simple and informative.

All I wanted to know was what a marking on a pack of bolts meant. For example 1/4 20 1.5. I had guessed that the last number is probably the length by measuring the bolt. But the rest of it? Now I know it means: diameter of the screw or bolt, number of threads per inch and length of body.

Walmart's new answer to rising costs is scan and go. You walk in and take a scanner and go get your items. You would scan each item with the scanner or app on your phone and then place them in the shopping cart. When you are done you would check out at a machine and show the recipe to the gest greeter at the door.

And on github:

If you're using Debian, use Synaptic Package Manager. And similarly use your linux distro's package manager. Look for openshot, one word. Installs without a fuss. You will find an icon in your start menu.
