Power Failures Today, Downtime

I take the unusual approach, of hosting my Web-site, including this blog, on a private PC I have at home, acting as server. I’m not suggesting that everybody do it this way; it’s only how I do it. For that reason, the visibility of my site and blog, are only as good, as the quality of my Internet connection, as well as the continuity of my power supply.

Unfortunately, my immediate neighbourhood was subject to multiple power failures this evening, from 16h25 until 1815. For that reason, my Web-server was offline, until about 18h50. I apologize for any inconvenience to my readers.

BTW, This last server-session ran uninterrupted for over 60 days, as a sign of how rare such failures have been, in recent months.

Power Failure Today, Downtime

I take the unusual approach of hosting this blog and site, on a server, that is running on my personal computer at home. I don’t recommend that everybody do it this way; this is only how I do it. That makes the availability of my blog and site no better, than the reliability with which I can keep my PC running, as well as that, of my Internet connection.

Unfortunately, I experienced a brief power failure this morning, between 8h45 and 9h00. As a result, this site was down until about 9h40. I apologize for any inconvenience to my readers.

BTW, There have been remarkably few failures in the recent 3 months or so.

If one wanted to extend trigonometry to complex numbers, I think the following two worksheets would exemplify how that can be done:
