Buttons at top of almost every page. If no one reads these things, there's not much point in me writing them. (Is that your message to me?) And no one reads them if they don't hear about them. Google searches cater for the masses. And the masses use a smartphone and have a 15 second attention span. These pages aren't for that audience.
Philosophy of design.... How to make things. Computer programs. Databases. Electronic circuits. The concepts here are important to many of the things I try to help you with in many parts of this site... and, if you'll forgive my pomposity... perhaps even in "Life" generally!
Libre Office / Open Office database ("Base") tutorials for novices. This set of tutorials started in 2006. They may help you not waste time, the way I did! Contains links to other Open Office tutorials, too. This database may be free, but it is very good, very capable. You can stop paying Microsoft to use Access. And while you are at it, you are learning to use something you can continue to use when you move to Linux or Mac.
Getting started, general electronics. Some of the electronics you need for having fun with Arduinos, etc, you can pick up as you go along. You really do need to understand the basics to be able to proceed smoothly, instead of stumbling from confusion to confusion. When you are ready to face that fact, I hope what is on the menu this link takes you to will be helpful.
Connecting things to LANs and the internet: Not for the faint hearted... but if you are ready for a "from the ground up" series of essays on this subject, this is for you. Tells you about, say, putting IP cams online. Webservers... your own, not using a hosting service. Arduino, ESP8266s and other IoT devices. These essays give you the fundamental knowledge, in a carefully planned sequence. It isn't hard, when you follow the sequence... but there are many bits to get right. This essay written after at least 15 years of learning the hard way, and multiple previous attempts.
Lazarus tutorials for novice and intermediate programmers. Lazarus is free and multi-platform, and well worth the time of someone who is serious about learning a bit about programming, or wanting to use a "grown up's" general purpose programming language. It grew out of the proprietary Delphi, and the tutorials from the next link will often apply directly to Lazarus programming as well.
Delphi tutorials for novice and intermediate programmers. Probably my most important contribution to the internet. Delphi programmers are, I admit, an esoteric audience! These tutorials should also inform the Lazarus programmer, please do contact me if you find something in one of them won't also work in Lazarus.
Guide to programming in Pascal... with a link to a suitable free compiler. Graded exercises. (Lazarus and Delphi are Pascal-based.)
Page of links to material for schools or hobbyists interested in weather monitoring, especially via the Dallas / Maxim 1-Wire / MicroLan / iButton.

Ad from page's editor: Yes.. I do enjoy
compiling these things for you... hope they are helpful. However..
this doesn't pay my bills!!! If you find this stuff useful, (and you
run an MS-DOS or Windows PC) please visit my freeware and shareware
page, download something, and circulate it for me? Links on your page
to this page would also be appreciated!
