With gears somewhat working in the Linkage program (there is a small glitch to fix still), I need to figure out what to do next. I have a list of user requests as well as a list of things that I want. I’m not sure what to do…
Continue readingI fixed the one problem that I had with the app where I had allowed it to use landscape orientation. When the user rotated the device, the screen would go blank and the on-screen-keyboard would disappear. Rotating it back didn’t restore the keyboard making the app useless. Now…
Continue readingI just finished writing my first Swift app for iOS. It’s the very common tutorial app “Tip Calculator” which accepts a bill amount and then shows a tip and total based on the selected tip percentage. The tutorial is from the book iOS for Programmers: An App-Driven Approach…
Continue readingI finally figured out how to change that Box Transport Mechanism from my previous post into a Linkage mechanism that works. All I needed to do was get rid of one of the links and then add a link to do the same thing using connectors that are…
Continue readingThe Stephenson Value mechanism on a locomotive is a mechanism that the Linkage program can’t simulate. I was asked by a user for help with a box transport mechanism and I see that it is another mechanism with the same issue Box Transport Mechanism In case that YouTube…

I will get forwarded emails from that address for a while, but please don’t use it anymore. I can be reached at my gmail address “rectorsquid”. Dave
Continue readingI just updated the Linkage 3.0 Beta files. The new version has a bug fix that caused some geared mechanisms to fail in the simulator. This came about because of how I now allow a gear to be placed on an input anchor, but be fastened to another…
Continue readingToday’s post is about writing code. More specifically, about document and view architectures. Code isolation, or encapsulation, is where one piece of code knows little or nothing about another. Right now, I am dealing with keeping the Linkage document separate from the Linkage view of that document. The…
