OCEAN STAR

“Could there be, in our universe, a sun surrounded by an ocean of water the size of our solar system? Kept warm enough, so that you had a super ocean, billions of miles in diameter, with a frozen outer crust and ring system …” – Dr. Freckles

PYTHON SCRIPT: JS8 RSS NEWS READER

I started working on a project with my friend Justin in 2022, we were able to put several months in and conducted a lot of experiments.

To learn more about what we have been trying to do: RADENGINEERING.TECH

We haven’t given up on the project, but we both have to make money, to get by, and we don’t have the time to put much more into it …

In order to promote this project, I was asked to build a simple RSS newsreader, operating using JS8 protocol, accessing some of the software’s API and using log files for monitoring. Not a lot of code allowed for a pretty cool experience, where headlines were being sent using CB RADIO, 11M, 27.245 MHZ.

Do with it what you will.

#This is a news agent/script, a prototype
#Service, utilizing JS8 as a proxy agent
#to encode messages and decode from our
#transceiver

#JS8 Callsign for this service - N3W5 or NEWS ...

#1. monitor directed file for requests
#2. respond to new requests
#3. grab RSS feed data

#there are a few python modules that need
#to be installed: maidenhead, feedparser, bs4
# anyascii, and perhaps one or two others
# just be comfortable using pip3 to install
# these other modules / libraries

ROBOT LIFEGUARD PROBLEM

Robot lifeguard … at pools.

So if your kid falls in, they don’t drown if you’re not around.

(wake me when that happens)

(it seems like a trivial problem – or is it?)

Think about the swimming pool scene in the movie “Caddyshack” (1980), how does a robot navigate that scenario? – lots of kids screaming, superficially they seem like they’re drowning.

A heuristic database might include a rule that says: “must be below the surface, this long …” … That’s a simple rule. As long as the robot can determine if a child has been below the surface too long – but this too gets harder as you add children to the pool, or other objects.

It’s not a non-trivial problem.

Twitter: script to UNBLOCK all blocked users …

Link: https://lucahammer.com/2018/08/09/unblock-all-blocked-twitter-accounts-at-once

  1. Go to dev console in browser on settings page of twitter, for blocked accounts, in focus.
  2. Open console for javascript.
  3. Paste in the scriptlet below and press enter.
let autoUnblock = setInterval(function() {
    window.scrollBy(0, window.innerHeight);
    document.querySelectorAll('[aria-label="Blocked"]').forEach(function(account) {
        account.click()
    });
}, 1000);
