Coronavirus Covid-19 Quizzes

In the interest of getting more information on the Covid-19 virus out and in easily digested form, I’ve developed three educational quizzes. Those quizzes have been added to my existing quiz web site.

The Covid-19 virus is new and much is being learned. New discoveries are made and our knowledge refined every day. There are changes in what’s known every day. In compiling information for these quizzes, I found many examples where information published a week or two ago is already obsolete. These quizzes are based on the best information I could find as of March 18, 2020.

I will do my best to keep these quizzes up to date. Please comment here on this blog post with any updates or incorrect information you may find. Ideas for additional questions or additional quizzes are welcome. In fact, this blog post exists so that you have a place to leave comments.

Educational Quiz Site

A new web site has been created with the intent of teaching by means of quizzes.

The new site is located here:  https://quiz.shuttersparks.net

If you are interested in authoring quizzes in any field or subject (credited to you, of course, if you wish) please comment below.

A New History Blog!

Relatively new on the Shuttersparks blog are the “On This Day” posts about important historical events in science and engineering. I started these here on my main blog but I see that these posts are going to drown out everything else. So, I’ve created a new blog just for these historical posts here: https://today.shuttersparks.net/

Hurricanes and Quizzes

The hurricanes of 2019 have begun in earnest. For a quick review and tutorial, here’s a fun tutorial-quiz on the Maya Paradise web site:

Protonmail IP Logging

Around the end of May 2019, a scandal erupted around Protonmail, the encrypted email service, associated with the CERN laboratory, and based in Switzerland. I keep running into this sensational item on social media and am weary of debunking it over and over. So, here’s a blog post about it.

This tempest in a teapot stems from a misleading tweet made by a Swiss lawyer, Martin Steiger, where he states that Protonmail “voluntarily offers assistance for real-time surveillance.” This came from a statement he heard in a meeting. The tweet made it sound like Protonmail offers surveillance to anyone who asks, or even offers it unasked for, so everyone freaked out.

What’s the truth? It’s actually pretty boring. All Swiss-based providers of Internet services are required by law to assist law enforcement when ordered to do so by a court of law. This is the same in virtually every country.

What was said and meant in the meeting that Mr. Steiger attended was that Protonmail cooperates with law enforcement when ordered to do so by a court without fighting the court order. The word “voluntarily” meant that Protonmail complies with Swiss law without objecting.

In the case of Protonmail, cooperating means IP logging, which is all Protonmail can do. The system is designed so they cannot decrypt the contents of emails.

Everything clear now?

Patents

Announcing a new page. In recent weeks, my patent “legacy” has come into the conversation. Looking them up is clumsy and time consuming, so I gathered the most interesting ones and published them on a WordPress page here, along with PDFs of the full patents. Now, I can send just one link.
