Internet of Things (IoT) Project-Part 2
(NO Caution) Agile development underway. I’m a big proponent of Agile development and this project is a perfect example. I built the initial version and a few tangential issues came up that were unexpected. In SDLC, this type of thing creates havoc, schedule disruptions and a mad scramble to adapt the overall plan to the…

Internet of Things (IoT) Project-Early Results
I’m having a noise problem with 2 of the sensor but here are the other 4 plotted in real time. The bottom line is the outside temperature. The others are in different places around the garage. Early results on the gradient tell me something is wrong with either the sensor designation, or perhaps the initial…

Internet of Things (IoT) Project-Project Plan
Start with the End in Mind. Goals Understand the nature of the temperature gradient relative to a heated building with attached enclosed space Notify me when there is a risk of garage stores beverages freezing (and possibly bursting) Notify me when data logging has stopped Reactivate a long dormant project Use Wireless Mesh Network…

Internet of Things (IoT) Project-Part 1
This project is a work in progress.I’m pretty close to being done with phase 1. The Project: (The need for knowledge.) From practical experience, I know that the temperature closer to the heated structure is warmer than further away. But how does it diminish? Is there an immediate drop or more of a gradual…

Tracking the Position of a live Mouse
Placecell research. That’s what it is called. In our brains, there are cells that become active when you are somewhere familiar. This is how we can drive home and not even remember taking the exit ramp off the highway. Anyway, I was recruited to help a memory and learning researcher correlate the physical…

Using Cognos Report Studio as a bulk email tool
I’m not referring to spam here. My customer needed a way to communicate with subsets of their customers. All of the (internal) customers were in a database and they were classified by which type of customer they were. Luckily the email addresses were also available. There was no budget to build a custom piece of software…

Infrastructure The silent project plan killer
In theory, you get a piece of software and install it and begin using it. That works maybe 30% of the time. Invariably, you run the install and various messages begin to pop up. Maybe you have a permission problem, maybe there is a pre-requisite that you don’t have, maybe it’s a platform learning curve…

Least Squares Linear Predictive Report with Cognos Report Studio
In a large corporation, things move extremely slowly. At my most recent job, if we wanted more disk space, it would take about 2 months to actually see the space. First there were the requests and signoffs, then the provisioning and people who ask you to justify the need, then the ordering and finally the…

Mobile App development with PhoneGap
A few years ago, I had an idea for an App. At the time, I did some research and felt that Appcelerator was the right way to go. I coded the core parts of the system but began to bog down in Graphics, scaling, screen resolution etc. Then other commitments took me away from my…
