Today is the 45th anniversary of the APL language as an actual computer system.
You can get more information on this from the following links:
At APL’81 a number of us participated in a sing-along of Michael’s “APL Blossom Time” that includes the title of this post. You’ll find the lyrics in Appendix A of his document.
We had a power outage in South East Oakville this afternoon and it really brought home how much we rely on the constant supply of electricity. Julia had gone out and I was busy working on another WordPress plugin. The computers went down except for a laptop and a netbook, which lost their internet connection because the router was down. By the time she got home the sun was setting and we were discussing restaurants for dinner because we couldn’t cook. The gas heat would run, but the fan wouldn’t blow, so it could get pretty cold.
The mobile phones partially worked, but only over the cellular network since our wifi was out. The iPhone made a pretty good flashlight, the Android was not quite as bright but was strong enough for Julia to find the big flashlight so she could find some papers she needed.
We have a tech museum shelf in the library that contains some of the wonder gadgets of the last century or two.
Here we have from left to right:
- entertainment (gramophone)
- light (oil lamp)
- database (spike)
- communication (rotary phone)
- finance (piggy bank)
- desktop publishing (typewriter)
The only one that requires power is the phone but it runs on an independent supply. The two end devices were invented and promoted by the “Steve Jobs” of the turn of the 20th century, Edison. He was as difficult to work with, he even got himself fired from a couple of his early jobs for being too creative.
All of the museum gadgets are functional, but the oil lamp is out of fuel, I’m going to fill it up as soon as I can find some lamp oil.
Luckily the power came back on in time so we didn’t need to go out or fire up the barbecue.
Today I released our first public WordPress plugin, “Simple Access Control”. The plugin is as simple as its name implies, there is only one optional configuration setting and only one widget to control access.
Use of the plugin is described on the Simple Access Control page.
The code is written in procedural PHP so it can be followed by programmers at any skill level, it’s well commented and was built with use as an example in mind. Feel free to pick it up and use it or modify it to your requirements. I will be posting an annotated version of the code as a tutorial in the near future.
In 2005 my wife Julia and I founded Devondev Inc. to provide software and virtual assistance (VA) services. Between 2007 and 2011 we mainly provided VA services and web site development through Prime Admin Solutions. Starting in September this year we have expanded to provide WordPress customization using plugins and themes as well as consulting and custom database and content management development using PHP, Java, MySQL and Oracle.
This blog will be dedicated to news from Devondev and commentary on technical issues.
