LoTW – Certificate Renewal Time

Seems a Logbook of the World (LoTW) “certificate” has to be renewed every 36 months, as at the end of January an emailed notice arrived saying:

According to our records, your ARRL Logbook of the World Callsign Certificate for:

K9ZW – UNITED STATES OF AMERICA

expires at:

Feb 9 16:39:02 2023 GMT

To continue submitting log data for this call sign and entity, you must renew your Callsign Certificate. Renewal is quick & easy before your Callsign Certificate expires; if your Callsign Certificate expires, a new one will need to be requested.

Instructions for renewing can be found at:

Apparently ARRL’s LoTW has a window, where you won’t be told you should renew until there is a tight window, which is you do not renew before that deadline your certificate cannot be renewed. If you go past the deadline a different process creating a new certificate is required.

February 16th is BBS Day! – Less than 3 weeks away!

Less than 3 weeks away is the 45th anniversary of when the first public facing BBS (Bulletin Board System) went active.

The very first BBS

A wide group of BBS sysops and users are marking the anniversary – details at the BBS Day website: https://bbsday.org/

The Great Blizzard of 1978 was one of the worst storms in Illinois’ history. One-hundred-mile-an-hour winds whipped up snow drifts as high as 12 feet. Wind chills were so low they caused railroad tracks to buckle and break. Northern Illinois, especially Chicago, ground to a halt. And a couple of snowed-in computer nerds created a major technological achievement. It was Feb. 16, 1978, just after the great blizzard, when two Chicagoans, Ward Christensen and Randy Suess, launched the world’s first computerized bulletin board system (BBS).

Link to the transcript: https://www.northernpublicradio.org/education/2021-02-15/this-week-in-illinois-history-worlds-first-bbs-goes-live-feb-16-1978

There was an online documentary made about the event: https://www.youtube.com/watch?v=Dddbe9OuJLU

The whole thing was pretty simple – two 8″ floppy disks a Altair 8800 clone “Vector 1” connected by an S-100 board, and a 300bps modem.

https://pcmuseum.tripod.com/bbs.htm explains how the BBS was here before there was a world wide web!

I didn’t join into the BBS game until about 1984, where I started to operate as a “point” and then started a USA based full time BBS in 1988.

My present itineration of SPOT BBS (SPOT= S.P.O.T. = Someone Playing On Transistors) is at spotbbs.k9zw.com ssh port 1122, telnet port 1123, and when the html part works html port 8888.

SPOT BBS is the same 1:154/154 FidoNet Node Number as when I mothballed the original 30 years ago, though today it runs MysticBBS as the original OPUS CBBS software is long obsolete..

Do you control, much less own, your Computer Desktop?

It had become pretty obvious that our computer “ownership” is far from “true ownership” in that outside parties affect many aspects of our usage. In many cases they can change how we do our work or blur the line on what we own.

Microsoft recently decided that it was unilaterally changing the location, format, and content of my work desktop Outlook GUI. To hell with my established workflow, and since I was a mere end-user they felt no notification was even needed.

Some discussion:

https://techcommunity.microsoft.com/t5/outlook-global-customer-service/new-location-for-the-mail-calendar-people-and-other-modules/ba-p/3596278

Microsoft has absolutely no science presented – no ergonomics studies, no survey results, no study of the screen types users actually use, nada…

Basically they somehow feel they “own” our work computers.

Now not to throw mud at just Microsoft, Apple has decided that they “own” any hardware purchased from them and feel they are entitled to run scans of local files, reporting back to Apple what they find.

Some background:
