If like many you have been starting gardens and planting rather than traveling and visiting in recent months, there is one important thing to consider lately – severe weather reports including frost on your crops. I noted there was a little red (!) alert icon on an Android weather widget, but there seems to be no such alert for desktop computer or Linux computer or phone. It is a fairly simple to make this alert though with a simple script:

These past few weeks have certainly been trying for some communities with power outages, winter weather and utility failures. Ham radio is a very good way to communicate in your local community, but what if lots of other people are on the local repeater?

Once in awhile a service may get compromised script or item in it – in a recent case, a Zoom link will actually take you to some random site as part of some sort of adware campaign??? However a closer look shows it is very important to test your links on email or sites:
The link I saw recently actually had a very odd looking script – script in a production service is generally minified sometimes, but won’t be oddly obfuscated or base64-encoded. The suspicious part of this script starts out in the <body> with an odd looking launchBase64:
