Questions About APIs and Dirty Data and Best Practices

So I’m working on this Farmers Market Locator project, and I’ve got a pretty basic version up and running. Everything is client-side. And I’m using the New York State Open Data API to get the information on the farmers markets. Right now, all that happens when you use the site is a query to Google to find out where you are, and then a query to the NYSOD API to get the nearest markets’ info, and then some Google Maps API stuff. But some of the data is a little dirty: missing spaces in addresses, that kind of thing.

More complications: There’s a bunch of features I want to add, some of which involves incorporating data from the USDA Farmers Market API. Now the USDA API has a little more info about the markets, like what kind of products are sold at each market. This data might also be pretty dirty. And as far as I can tell, the only way to match up markets between the two APIs is to do string matching. (Meaning that, having determined that the Union Square Farmers Market is the closest to your location, I then have to search the USDA API for “Union Square Farmers Market”)

Is there a better way to approach matching up the markets between the two different APIs? Do I need to switch to a back-end solution? What’s the best way to clean up the dirty data? Should I be pulling this info into something else, like a Google Spreadsheet, clean it up there, and make queries to the spreadsheet instead of NYSOD?

I don’t even know how to approach this.

Edit: Adding links to raw JSON.

http://data.ny.gov/resource/qq4h-8p86.json

http://search.ams.usda.gov/farmersmarkets/v1/data.svc/zipSearch?zip=10008

Edit: Some suggestions have been made…but as usual they only spawn new questions.

  • Best way to match markets:
    • search name (problem: not standard)
    • search address (problem: not standard)
    • use URLs as keys (problem: what URLs??!!)
  • Cleaning up dirty data:
    • You can use a back-end solution with some data store OR you could do it all in JS. If you were to do it all in JS you would just have to call a few API’s, compare the data returned, fill in missing data from one API with data from another. You would also need to decided which would have priority if there was a conflict. (problem: wouldn’t doing all that matching, comparison, and cleaning on the client-side make it slower?)
    • I think you are wise to consider grabbing the data, cleaning it up and storing it under your own backend. This allows you to keep your app up and running even if they change their format. (sure your data might get stale, but probably not by much, and it would buy you time address any new formatting from your sources) You could pull down the source data, create your combined json set, and just use that. (depending on how huge all the data was) While a backend solution might sound really complicated, it doesn’t have to be. A google spreadsheet could work, or Google Fusion tables, or Parse.com, FireBase.com, or Tableau.

So far the best suggestion is pretty close to my initial idea, but I’m hoping to get some more feedback on this before I commit myself. Chime in!

Getting Rid of Blue Links in Emails for iOS

I recently put together an email for JNF regarding a fancy event in NYC. The email was pretty great-looking, medium blue background color, white copy, black NYC skyline image at the bottom, really different from what we normally send out. Unfortunately, after hitting “Send,” I was almost immediately bombarded with complaints that on iOS devices, certain parts of the text were turning blue – a shade of blue that really didn’t show up well against the medium blue background color. Whoops.

JNF-GoE-blueJNF-GoE-white
Apparently, iOS devices highlight pieces of text that might be useful in your calendar or mapping application: dates, times, locations, etc. So all that copy was now practically illegible. I did some digging around the internets, and this article turned up repeatedly as the definitive solution: Update: Banning Blue Links on iOS Devices. Great! The email was scheduled to be resent in a couple of weeks anyway, so I would implement the fix for the resend.

Whomp Whomp. None of the suggestions in the article worked for me. After hours of testing, I finally gave up, got rid of my lovely blue background, and applied the same color (nearly indistinguishable from the color iOS uses) for the text. If anybody out there has an alternate solution for the blue link problem, I’d love to hear about it.

After this experience, I have several questions: How do other people conquer the blue link demon? Why does email (easily the most used form of communication for the past decade) still rely on technology and standards from the early 90s?

Thinkful Unit 3 Comprehension Checks

Lesson 1

Assignment 1

Describe what event binding is and how it can be used to make your pages interactive.

Event binding attaches a handler to an event for the DOM elements.

Events can be:

  • A mouse click
  • A web page loading
  • Taking mouse over an element
  • Submitting an HTML form
  • A keystroke on your keyboard

So you can have elements appear, disappear, animate, etc., based on events.

What are the advantages of using the first block of code over the second?

$(‘#my-div’).on(‘click’, function() { ...do stuff...; });
vs.
$(‘#my-div’).click( function() { ...do stuff...; });

the ability to bind to multiple events at once
use “namespaced” events

What does .preventDefault() do, and when would you use it?

prevents the default action of an event, like clicking on a link or a button

What does .stopPropagation() do, and when would you use it?

prevents ‘event bubbling’ – when an event is triggered for a nested element and then is triggered for every element up the DOM.

How and why would you use this in an event handler?

this allows you to target a specific element, while still binding to a high-level element. This is called event delegation.

Give an example of event delegation and explain its advantages.

Event delegation lets you bind fewer event handlers, which can be a big performance gain. It also lets you bind to parent elements and know that event handlers will fire as expected even if the contents of that parent element change.

Assignment 2

How can you set the fast and slow speeds for jQuery animations?

The predefined speeds are specified in the jQuery.fx.speeds object; you can modify this object to override the defaults, or extend it with new names:

// re-set an existing predefined speed
jQuery.fx.speeds.fast = 50;
// Since we've re-set the 'fast' speed, this will now animate over the
// course of 50 milliseconds
$( '.hidden' ).hide( 'fast' );

Why might you be further ahead using CSS animations instead of jQuery for mobile devices?

In modern browsers, and especially on mobile devices, it is often much more efficient to achieve animations using CSS rather than JavaScript.

What must you do to the spelling of properties like font-size that have hyphens if you want to reference them in a jQuery animation method?

If you want to animate a CSS property whose name includes a hyphen, you will need to use a “camel case” version of the property name if you do not quote the property name. For example, the font-size property must be referred to as fontSize.

How can you stop a jQuery effect?

.stop() will stop currently running animations on the selected elements.
.delay() will pause before the execution of the next animation method. Pass it the number of milliseconds you want to wait.

Lesson 2

Assignment 1

Memorize both syntactically correct ways you can call jQuery’s .ajax() method.

$.ajax({
 url: '/data/people.json',
 dataType: 'json',
 success: function( resp ) {
 $( '#target').html( resp.people[0].name );
 },
 error: function( req, status, err ) {
 console.log( 'something went wrong', status, err );
 }
});
$.ajax( '/data/people.json', {
  type: 'GET',
  dataType: 'json',
  success: function( resp ) {
    console.log( resp.people );
  },
  error: function( req, status, err ) {
    console.log( 'something went wrong', status, err );
  }
});

What are success and error callbacks, and how do they work with .ajax()?

Success Callback: A function to be called if the request succeeds.
Error Callback: A function to be called if the request fails.

Make sure you understand that how and why the return command of an ajax() call will return before the server to which the request was made has responded.

AJAX requests run asynchronously —  the $.ajax method returns before the request is finished, and this function’s return statement runs before the request is complete.

What is JSON and what can you use it to represent?

JSON is a string representation of data.

What are the .get() and .post() methods?

If we’re just making a simple request — and if we don’t care about error handling — jQuery provides several “convenience methods” that let us use an abbreviated syntax. Each of these methods takes a URL, an optional data object, and an optional callback for handling a successful request.

$.get( '/data/people.html', function( html ){
  $( '#target' ).html( html );
});
$.post( '/data/save', { name: 'Rebecca' }, function( resp ) {
  console.log( JSON.parse( resp ) );
});

We can send data with our request by passing an object as the second argument to one of the convenience methods.
For a GET request, this data will be appended to the URL as a query string; for a POST request, it will be sent as form data.

How can you use jQuery to serialize and submit form data?

The .serialize() method converts form input to a query string format.

.ajax() calls return a jqXHR object. What are the .then(), .done(), .fail(), and .always() methods on jqXHR objects for?

.then() – attach success and error callbacks
.done() – attach success callback
.fail()– attach error callback
.always() –  attach callback that runs on success or failure

What is JSONP and what does it allow you to do?

Allows you to use data even though it is hosted on another server.

What does an ajax call with JSONP look like in jQuery?

$.ajax({
 url: '/data/search.jsonp',
 data: { q: 'a' },
 dataType: 'jsonp',
 success: function( resp ) {
 $( '#target' ).html( 'Results: ' + resp.results.length );
 }
});

What is the .getJSON() method?

A convenience method to make a JSONP request; if the URL includes callback=? or similar, then jQuery will treat it as a JSONP request.

$.getJSON( '/data/search.jsonp?q=a&callback=?',
 function( resp ) {
 $( '#target' ).html( 'Results: ' + resp.results.length );
 }
);

How can you use $.Deferred() to return a promise?

The deferred.promise() method allows an asynchronous function to prevent other code from interfering with the progress or status of its internal request.

Lesson 3

Assignment 1

What is JSON?

JSON (or JavaScript Object Notation) is a lightweight, easy and popular way to exchange data.

What’s a callback and how does it work in the context of a jQuery .getJSON() request?

A callback is a function that is passed to another function to run.

What is JSONP and what does it allow you to do?

JSONP (or JSON with padding) allows a script to fetch data from another server on a different domain.

Assignment 2

What is encapsulation and why is it important?

Encapsulation in an important organization concept for code. It separates code into distinct pieces.
Broadly, encapsulation does one or both of these:

  • restricts access to some of the object’s components
  • facilitates the bundling of data with the methods (or other functions) operating on that data

How can you use object literals to namespace functions?

An object literal is perhaps the simplest way to encapsulate related code. It doesn’t offer any privacy for properties or methods, but it’s useful for eliminating anonymous functions from your code, centralizing configuration options, and easing the path to reuse and refactoring.


// An object literal
var myFeature = {

    myProperty: "hello",

    myMethod: function() {
        console.log( myFeature.myProperty );
    },

    init: function( settings ) {
        myFeature.settings = settings;
    },

    readSettings: function() {
        console.log( myFeature.settings );
    }

};

myFeature.myProperty === "hello"; // true

myFeature.myMethod(); // "hello"

myFeature.init({
    foo: "bar"
});

myFeature.readSettings(); // { foo: "bar" }

The object literal above is simply an object assigned to a variable. The object has one property and several methods. All of the properties and methods are public, so any part of your application can see the properties and call methods on the object. While there is an init method, there’s nothing requiring that it be called before the object is functional.

Explain the DRY concept.

Don’t repeat yourself; if you’re repeating yourself, you’re doing it wrong.

Thinkful Unit 2 Comprehension Checks

Lesson 1

Assignment 1

What is the DOM (Document Object Model) and how does it relate to JavaScript/jQuery?

The Document Object Model, normally abbreviated to DOM, creates a hierarchy corresponding to the structure of each web document. The DOM is the API through which JavaScript interacts with content within a website.

Why would you choose jQuery over JavaScript to add interactivity to your web page?

jQuery is designed to make many JavaScript development tasks much easier.

Is there a difference between the following: jQuery('h2'); vs. $('h2');?

No.

Why is it oftentimes important to wrap your jQuery functions in the following?
$(document).ready(function () {do something;});

To make sure the page is completely loaded before running scripts.

How do you get jQuery into your web page?

Download the jQuery library from jQuery.com or include jQuery from a CDN, like Google.

How would you select an element vs. a class vs. an id in jQuery?

$( "div" );
$( "#myDiv" );
$( ".myClass" );

Describe the difference between and provide an example of each of the following jQuery selectors:

descendant selector
jQuery descender selector (X Y) is used to select all elements matched by ‘Y’ that are child, grandchild, great-grandchild, great-great-grandchild..(any levels deep) of a ‘X’ element.
Ex: $('form input'); ‘ selects all elements matched by <input> that are descendants of an element matched by <form>.

child selector
jQuery child selector (X > Y) is used to select all elements matched by ‘Y’ that are child of a ‘X’ element.
Ex: $('form > input'); ‘ selects all elements matched by <input> that are child of an element matched by <form>, Only child element will match, grandchild, great-grandchild will not match.

multiple selector
Selects the combined results of all the specified selectors.
Ex: $("div,span,p.myClass"); – selects all divs, spans, and paragraphs with the class “myClass”.

What does it mean to ‘traverse the DOM’ and how do you do it?

jQuery lets us “traverse” ‘ or move through ‘ the HTML elements that make up our page. First, we make an initial selection, and then move through the DOM relative to that selection.

What is ‘method chaining’? Provide an example.

You can perform multiple methods on the same set of elements.

<div id="divTest1"></div>
<script type="text/javascript">
$("#divTest1").text("Hello, world!").css("color", "blue");
</script>

Which methods can you use to add a new node to the DOM?

.append()
.add()
.insertAfter()

How do you delete a node from the DOM?

.remove()

Explain how (and why) to use ‘this’ in a jQuery function.

this is a special keyword that is used in methods to refer to the object on which a method is being invoked.

What is the ‘data tag’ in HTML5 and how do you access it in jQuery?

The HTML tag is used to store custom data private to the page or application.
You can access the values of the data attributes like this:

<img id="pic" src="picture.jpg" data-large="picturelarge.jpg" data-productid="52"
data-license="creative commons">
$('#pic').data('productid') // 52

How can you use variables to reuse jQuery objects in a block of code?

jquery Object Methods

Which jQuery methods can you use to add and remove a class?

.addClass() and .removeClass()

What methods can you use to make an event handler listen for keyboard inputs?

.keydown(), .keypress(), .keyup()

How might you use the .val() method to retrieve user input from a form submission? If you ultimately want to get an integer as opposed to a string value, what do you need to do?

var quantity = +$(this).val();

Why would you use event.preventDefault() in the function of an event handler that listens for clicks on a link?

To keep the page from jumping around.

How do you use jQuery to get and set style properties of a selected jQuery selection?

$(this).css("background-color", "#252b30");

Why might it be better to manipulate the style of a DOM element by toggling its class, as opposed to getting and setting properties directly?

Because it keeps the appearance and function separate, making it easier to maintain and manipulate.

What does the animate method do?

Adjusts a CSS property pixel by pixel in order to animate it.

Lesson 3

Assignment 1

What is the relation between JavaScript and Java?

Nothing. Silly marketing people.

What are the six basic types of values in JavaScript?

Numbers, strings, booleans, objects, functions, and undefined values

Why would the following JavaScript function not return the value 2?

function squareRootSquared() {
    var squareRoot = Math.sqrt(2);
    var squared = 2 * squareRoot;
    return squared;
}

Calculations with fractional numbers are generally not precise.

What does the % operator do? For instance, what would result would you get from 101 % 100 ?

Modulo, like remainder. So 101 % 100 would be 1.

When would you need to ‘escape’ a character in a string with a backslash?

Quotes inside quotes, newlines, backslashes, tabs

How do you concatenate two or more strings?

+ operator

How do the logical operators && , || , and ! work in JavaScript?

The && operator represents logical and. It is a binary operator, and its result is only true if both of the values given to it are true.
|| is the logical or, it is true if either of the values given to it is true.
Not is written as an exclamation mark, !, it is a unary operator that flips the value given to it, !true is false, and !false is true.

What is the order of precedence for operators (keeping in mind that you can always use parentheses when in doubt)?

Division and multiplication always come before subtraction and addition. When multiple operators with the same precedence appear next to each other (1 – 1 + 1) they are applied left-to-right.

What is an expression in the context of programming? How is this different from a statement? (HINT: Think about side effects).

A piece of code that produces a value is called an expression. An expression can be content to just produce a value, but a statement only amounts to something if it somehow changes the world.

What are reserved words?

javascript keywords that cannot be used as variable names.

How do you implement a while loop? How do you implement a do loop? How do you implement a for loop?

While loops: First, a ‘counter’ variable is created. This variable tracks the progress of the loop. The while itself contains a check, usually to see whether the counter has reached some boundary yet. Then, at the end of the loop body, the counter is updated.
Do loops:
For loops: All the statements that are related to the ‘state’ of the loop are now on one line. The parentheses after the for should contain two semicolons. The part before the first semicolon initialises the loop, usually by defining a variable. The second part is the expression that checks whether the loop must still continue. The final part updates the state of the loop.

Why is indentation important (though not necessary) in JavaScript?

The role of the indentation inside blocks is to make the structure of the code clearer to a reader.

What happens when the break keyword is reached in a loop?

It immediately jumps out of the current loop, continuing after it.

What is the syntax for a function in JavaScript?

function add(a, b) {
return a + b;
}
show(add(2, 2));

Why might you define a function within another function?

Because the computer looks up all function definitions, and stores the associated functions, before it starts executing the rest of the program.

Give an example of a recursive function. Why is the elegance of the recursive function not always preferable in JavaScript?

function power(base, exponent) {
 if (exponent == 0)
 return 1;
 else
 return base * power(base, exponent - 1);
 }

In JavaScript, running through a simple loop is a lot cheaper than calling a function multiple times.

What is an anonymous function, and why might you use one?

A function that doesn’t have a name.

Lesson 4

Assignment 1

What is a property in JavaScript? How do you add a non-existent property to an object?

A property is an association of another value with a value. If you have a JavaScript value with the type object, you can add and remove properties at will. If a property that does not yet exist is set with the = operator, it is added to the object.

 var empty = {};
 empty.notReally = 1000;
 show(empty.notReally);

What is an array? What do the following array methods do?

A set of numbers or objects that will follow a specific pattern
myArray.push() – adds an item to an array
myArray.pop() – removes an item from an array
myArray.join() – builds a single big string from an array of strings

How would you get the value of the item at a given index in an array?

var valueAtIndex1 = myValues[1];

What does the new keyword do in JavaScript?

– It creates a new object. The type of this object, is simply object.
– It sets this new object’s internal, inaccessible, [[prototype]] property to be the constructor function’s external, accessible, prototype object.
– It executes the constructor function, using the newly created object whenever this is mentioned.

Thinkful Unit 1 Comprehension Checks

Lesson 1

Assignment 1

Explain in words your grandparents would understand what happens after you type a URL in your web browser and hit ‘Enter’.

Browser reads the URL, finds the rules for talking to another computer, finds the name of the computer serving the webpage, finds which specific webpage you are looking for. From the name of the computer where the webpage lives, the browser can find the computer’s IP address(like a phone number). The browser connects to the IP address (like calling someone and they pick up the phone) and then if it can find the specific webpage you asked for, it shows up on your screen. If it can’t (like if you call and someone picks up but the person you are looking for isn’t home or its a wrong number) then it shows a 404 page.

What is a DNS, and what is its purpose?

DNS is like a phone book for computers. It’s how you can connect to another computer from your own.

What is a server and what is a path, and how do they relate in a URL?

The server is the computer where your webpage lives. The path tells the computer where the file you are looking for is.

Assignment 2

What do the ‘hypertext’ and ‘markup language’ in HTML mean, respectively?

Hypertext is simply the idea of documents that are capable of being linked together.
Markup languages are used to annotate and add semantic structure, or meaning, to a text document.

What is an HTML tag?

Tells the browser what different pieces of text are (list, header, paragraph, etc.)

What’s the difference between a span and a div?
The div tag is used to divide section of a webpage and a span tag is used to divide up text.

What is the doctype tag, and where does it go?

It goes at the very top of the HTML file. It tells the browser what version of HTML you are writing the document in.

Lesson 2

Assignment 1

Explain what it means when we say that CSS is responsible for presentation (vs. HTML, which is responsible for content)?

CSS adds color, size, columns, typography, images and layout

What is a selector? What is an element? How are they related in CSS?

The CSS selector is the HTML element we want to affect.

What is the general form for a CSS declaration (HINT: It’s a combination of the terms value, selector, property).

h1{color:#fff;}
selector:{property:value;}

What is a descendant selector, and how does it work?

Descendant selectors are similar to family trees; you start with the parent element you wish to select, add a space, and continue naming any interior elements until you’re arrived at the specific element you wish to select.

Assignment 2

How would you implement inline styles?

<p style="color:#fff;">text</p>

How would you implement internal styles?

<style>
p { color:#fff; }
</style>

How do you link to an external style sheet?

<link rel="stylesheet" type="text/css" href="stylesheet.css" />

Why is it generally a good idea to avoid inline styles?
Because it defeats the point of CSS, you would have to go back through everything to make style changes.

Lesson 3

Assignment 3

For a given styled div element, what would you expect the following margin settings to do:

div { margin: 10px; }
10px of space on the outside of the div (every side)

div { margin: 10px 10px;}
10px of space above and below the div

div { margin: 10px 10px 20px 5px;}
10px of space above the div, 10px of space to the right of the div, 20px of space below the div and 5px of space to the left of the div.

Explain the difference between the following values for the display property: block, inline-block, inline, none.

none: Turns off the display of an element (it has no effect on layout); all descendant elements also have their display turned off. The document is rendered as though the element did not exist.
inline: The element generates one or more inline element boxes.
block: The element generates a block element box.
inline-block: Basically, it’s a way to make elements inline, but preserving their block capabilities such as setting width and height, top and bottom margins and paddings etc.

What does the clear property do, and when would you use it?

return the document to its normal flow after floating

Explain the difference between absolute and relative positioning.

The relative value allows you to use box offset properties such as top, right, bottom and left. The absolute value breaks the element from the normal flow of a document.

What is the effect of setting a negative top margin on an element?

The element will be pulled up on the page.

Lesson 5

Assignment 1

What’s the difference between an HTML element and tag?

Elements are designators that define objects within a page, including structure and content. Some of the more popular elements include h1 through h6, p, a, div, span, strong, and em.
Elements are often made of multiple sets of tags, identified as opening and closing tags. Opening tags mark the beginning of an element, such as <div>. Closing tags mark the end of an element and begin with a forward slash, such as </div>.

What’s the difference between a relative and absolute path, and when should you use the former instead of the latter?

A relative path is used to point to something on the same computer or server. An absolute path is used to point to something on another computer or server.

Why would you often want to include multiple options when setting the font-family property for, say, the body element in your CSS?

Because the font you use might not be on your users’ computers.

Lesson 6

Assignment 1

How would you implement a gradient background for a given div?

 div {
 background: #70bf32;
 background: url('linear-gradient.png') 0 0 repeat-x;
 background: -webkit-linear-gradient(#a1e048, #6a942f);
 background: -moz-linear-gradient(#a1e048, #6a942f);
 background: -ms-linear-gradient(#a1e048, #6a942f);
 background: -o-linear-gradient(#a1e048, #6a942f);
 background: linear-gradient(#a1e048, #6a942f);
 }

How would you use an image as a bullet in an unordered list?

 li {
 background: url('tick.png') 0 0 no-repeat;
 list-style: none;
 padding-left: 20px;
 }

What’s the point of including the alt attribute in any and all img elements appearing in your HTML?

The alt attribute value is displayed in place of the image should the image not be available. Also, the alt text is the cursor tooltip text that may be shown when hovering over the image.

Learning Front End Web Development with Thinkful

Thinkful is an online learning community that combines online resources with personalized feedback and mentoring. They have a Front End Development course, and just added a Python course. I recently signed up for the Front End Development course, hoping to shore up my JavaScript and figure out some of the cool new features of HTML5/CSS3.

After looking over the syllabus, I was initially concerned, because they start with very basic HTML/CSS. Been there, done that. I’m confident in that skill set. But after voicing my concerns, both my mentor and the class coordinator assured me that I could skip anything I felt comfortable with and go straight to the JavaScript.

So this week, I’ll be doing a quick overview of HTML5/CSS3 features (beyond the new semantic tags), and then I’ll jump into the JavaScript/jQuery segment.

Here are some resources I’ve collected:

Road Map To Coding With HTML5: Tutorials and Guidelines

Top HTML 5 Tutorials from HTMLGoodies

Take Your Design To The Next Level With CSS3

HTML5 Rocks Tutorials

Dive Into HTML5

If you have any other useful resources, I’d love to see them!

My Ideal Twitter Client

I knew that the old-school Adobe Air TweetDeck was on the chopping block, but found out this morning that I have until May 7 to find a new Twitter client.

TweetDeck to be discontinued for Android, iPhone, and AIR on May 7th

I spent 2 hours this morning looking for a replacement, but haven’t found what I want yet. Nothing out there really replicates what TweetDeck does:

  • I want to the option to post to Facebook and Twitter simultaneously, but also separately. (I don’t actually need my Facebook newsfeed in the client.)
  • Desktop app. If I wanted to use Twitter in the bloody browser, I would do that.
  • I want the post box to slide up from the bottom or down from the top, but not overlay the timeline.
  • I want single column AND multi-column views.
  • I want the app to take up as little horizontal space as possible: 250-300px wide in single column view is fine.
  • Keep toolbars and column navigation buttons out of the way.
  • Autocomplete for usernames.
  • Retweet options.

I would add cross-platform to the list, but I don’t want to seem greedy. I work on a Mac, use Ubuntu at home, and sometimes I just have to boot into Windows. I would be happy to settle for a different app in each OS if it fulfilled all the other requirements above.

Someone, please tell me my perfect Twitter client is out there.

Volunteering for ScriptEd

For the past few months I’ve been volunteering once a week with ScriptEd, a non-profit organization that offers programming courses to students at schools in low-income communities in New York City. I co-teach 5 students at Harlem Village Academies for 2 -3 hours every Wednesday. So far, we’ve been covering HTML, CSS and JavaScript.

What’s cool about this group of kids is that they are self-selecting (yes, I see how this is also a short-coming, but it’s early days yet). ScriptEd is an after-school activity, rather than part of the normal curriculum, so they are really into learning how to code. They have stuck with it, through exams and SAT prep and baseball games.

This past weekend, ScriptEd had its first student hackathon. We had 11 students from 3 different schools and at least 12 volunteers (I lost track, since more people kept showing up over the course of the day) in addition to the regular teachers. We formed 6 teams, with 2 students and 2 volunteers each.

Our theme was CIRCLE, SQUARE, TRIANGLE.  We challenged the students to use their imaginations and create something awesome with these shapes — for example, students might decide to make the shapes bounce to the beat of a song, or have the shapes divide every time the user clicks on a shape.

The results were incredible. I was so impressed with what these kids came up with and were able to build with their rudimentary skills. It was really rewarding to see how excited they were to actually put their skills to use and build something they could show off.

Here are some of the projects our students came up with:
