1. reusable components - Good Morning. I have always been intrigued by repeatable patterns and reusable components. It started when I was building houses
2. construction - I ran a construction company for twenty some years. For fourteen of those years I built new houses on vacant city lots for first time homeowners. Typically we would build a dozen houses at a time.
3. construction toolkit - Some styles repeated. So I wanted to automate the process. I would create a 3D wireframe from a set of architects plans...
4. software development - and then I would write software. Here you see some AutoCad Lisp code that inserts floor joists into a 3D model. I could extract the vector data from the drawing and send it to a database to create stocklists and cut lists. Then I could print views of whatever we were building and hand them to the crew.
5. education and research - In 1998 I closed my business and went to college. I got a physics degree and then got funded to do graduate work. I worked mostly on memory and learning and pattern recognition and did a little bit on audition.
6. research and software - We built models of how the brain worked, coded them in MatLab and then tried them out on big datasets. In our models a sensory input would be represented by a feature vector. We would feed this into neural network. This little bit of code is using a feature vector to train the neural net. This I think is from a supervised learning model that gets trained up and then tries to recognize inputs it hasn't seen before.
7. education and research - I got involved in this big NSF grant related to learning. We were tasked with updating the way we teach based on what we now know on how the brain works. I started to going into classrooms and I really liked it. I got job in a new Boston public high school where every student had a laptop.
8. software and teaching - There was no curriculum and there was no software and no servers. I joined a team writing a Humanities curriculum and spent Friday evenings with a group of teachers hacking together servers and hosting Moodles and forums and wikis and writing code. We adapted platforms for the classroom and leveraged what was already out there. I wrote small scripts that would get the content into the wikis and on the smartboard and out to quizlet.

from construction to high school to es6

searching for a pattern language

"The elements of this language are entities called patterns. Each pattern describes a problem which occurs over and over again in our environment, and then describes the core of the solution to that problem, in such a way that you can use this solution a million times over, without ever doing it the same way twice"

the game -connect with a developer, show up at community meetings, provide cost (from prior accurate unit cost data with current prices) feedback on designs, win the bid pg:x-

"You can use [a pattern language] to work with your neighbors, to improve your town and neighborhood. You can use it to design a house ... and you can use it to guide you in the actual process of construction."

construction and software

automation, reusabilty

productivity and ease of use

research

Boston University - Dept of Cognitive and Neural Systems - models of cognition

computer vision, audition, movement memory and learning

I worked mostly on memory and learning and little bit on vision. In our models a sensory input would be represented by a feature vector. Typically these vectors got fed into a neural network where they mapped to stored memories. Recognition or learning depended on the network of neural connections and the weighting or strength of those connections. Learning modified them. Recognition found a match.

property management - I had left the building I was responsible for in reasonable shape. But after 10 years of having my time completely absorbed, I had a lot to do.

The pattern of my life for the last 5 years has been moving between construction consulting and developing a more formal set of software development skills

front end vs full stack

case study on reusability

reusability is the direction software development

'Each pattern is connected to certain "larger" patterns which come above it in the language; and to certain "smaller" patterns which come below it in the language. The pattern helps to complete those larger patterns which are "above" it, and is itself completed by those smaller patterns which are "below" it.'

following the direction

from jQuery to spaghetti

I guess I am a following this direction. First Ajax and jQuery let me inject content into a webpage. Then the front-end became cool. HTML5 and and javascript became more powerful...But jQuery didn't solve everything:

jquery code sample/app

"the heart of the pattern—which describes the field of physical and social relationships which are required to solve the stated problem, in the stated context."

    <ul id="rooms" class="current" data-role="listview" data-inset="true" data-filter="false">
    </ul>

    disp : function(idx){
        var temp = this.arr[idx]['setpt'];
        var timel = this.arr[idx]['clock'];
        var timep = time2PM(timel);
        var idx = this.arr[idx]['idx'];
        newTite ='  <li  data-ti="'+idx+'" data-timl="'+timel+'" data-temp="'+temp+'"><a href="#" ><img src="img/icons/pencil.png" title="edit" height="20px" width="20px"/></a><span>'+timep+' </span><span>'+temp+' °</span></li>';
        $(this.ulsel).append(newTite);
        this.bindEdit($(this.lisel));       
    },

In fact sometimes jQuery muddied up the relationships, obfuscated the pattern. What you see here is the code that produces the items in http://hvac.sitebuilt.net. Just looking at the HTML you have no idea what is going on. You have to dive deep into the javascript to find the relationships. Here is the method on the object that creates the HTML to show this.

Angular JS

the Model View Controller pattern

the magic of two way data binding

I started with Angular since it had a lot of Buzz. Big Meetup groups and lots of MEAN job listings. I have done a little with KnockoutJS and I found with Angular I didn't have to concern myself with mapping from JSON to the DOM. It just did it for me As long as I followed the 'Angular Way' everything was fine.

the direction of angular

"Now we can summon our multiplication table in our templates by using

instead of having to use ng-controller.

This is nice and glamorous, but we're still not any further into improving the quality of our code. We've just swapped one controller container for another and the HTML code is still out of whack." https://www.airpair.com/angularjs/posts/component-based-angularjs-directives

from controllers to directives

Cengage Learning hosts the Angular meetup. They are all excited about using directives to ecapsulate javascript and HTML into something that looks a lot like a web component. It can be styled and pick up the company-wide look and feel. And you can drop them in wherever you need them. here are a couple that I actually reuse.
