//
) will be ignored by the browser,
so you can safely include explanations about what your code is doing.
For example, in this snippet the first line will be ignored, and only
the second will be processed as code:
// Assign the value '3' to the variable 'count': var count = 3;If you need to write comments that stretch over multiple lines, you can begin them with
/*
and end them with
*/
. For example:
/* An example of a multiline comment */ var count = 3;Comments go a long way to making your code reusable and maintainable: they help you see at a glance what each line or section is doing when you revisit code you wrote months ago.
$('p').css({color:'green', padding:'3px'});
These aren’t special jQuery constructs—once again, it’s just
plain old JavaScript—but they’re great for encapsulating data to pass
around in your own functions and widgets. For example, if you pull data out
from some form fields, you can package them up into key/value mapped
pairs that you can then process further:
var id = $('input#id').val(); var name = $('input#name').val(); var age = $('input#age').val(); var data = { type: 'person', id: id, name: name, age: age }With the data all wrapped up, we’re able to easily pass it around and use it however we like. To access any one of an object’s values, we simply need to type the object’s name, followed by a period (
.
), followed by the key
associated with that value we wish to access. For example, given the
data
object defined above, if you wanted to check
to see if the type
property contained the string
'person'
, and alert the name
property if so, you’d write:
if (data.type == 'person') { alert('Hello ' + data.name); }
hover
and toggle
commands will end up driving you crazy, so to save your sanity you’ll
want to group logical chunks of code together.
We already had a go at doing this in the section called “Advanced Tooltips and Dialogs
” in Chapter 5, and if you go back and have a
look at that example, you’ll notice that almost all the code is
wrapped up in an object named TT
. This object is
much the same as the previous data
object (and all
the object literals we’ve been working with so far), except that it
also contains functions, as well as static
variables.
So when we wrote setTips: function() { … }
,
we were assigning that
function to the setTips
property of the TT
object.
Once that’s done, we can write TT.setTips()
to
execute the function. Now every function we write that has to do with
tooltips can be contained inside TT
. Because the
only object we’re declaring in the global scope (more on this in a
second) is TT
, we can rest assured that none of our
functions or variables will conflict with other JavaScript code on the
page. We refer to this technique as
namespacing, and refer to all our
TT
variables and methods as being part of the
TT
namespace.
Our namespace object can be given any name so long as it’s a
valid variable name. This means it can start with a dollar sign,
underscore, or any alphabetical character, lowercase or uppercase.
Additionally, the more unique and helpful the name is, the more
successful it will be (well, it worked for jQuery
($
) and underscore (_
)!). We’re
aiming to avoid clashes in function names.
TRKR
would be a good choice for StarTrackr!
It’s short, helpful in that it alludes back to our site name, and
fairly unique.
Here’s what we’re looking to avoid. Say you have a function
named exclaim
:
function exclaim () { alert("hooray"); } exclaim();// hoorayIt’s not especially inspired as function names go, but there you have it. Trouble is, some third-party code that you want to put in your site also has a function named
exclaim
:
function exclaim () { alert("booooo"); } exclaim();// boooooNow, when you expect the alert to show “hooray,” you instead see a disheartening “booooo.” Rather than simply picking another function name and risking the same result, let’s put our method inside the
TRKR
namespace:
var TRKR = {}; TRKR.exclaim = function () { alert("hooray"); };There’s no limit now to what we can do with the methods and properties of our namespace:
var TRKR = {}; TRKR.namespaces = "cool"; TRKR.boolean = true; TRKR.pi = 3.14159; TRKR.css = { "color": "#c0ffee", "top": 0 }; TRKR.exclaim = function () { alert("hooray"); };Now we can still let out a buoyant “hooray,” but there’s much less chance of other code stepping on our toes:
TRKR.exclaim (); // hooray TRKR.namespaces; // “cool” exclaim(); // booooooNamespacing code this way also means that it can be easily reused on other pages. All we need to do is plunk the
TRKR
object down in another page, and we’ll have
access to all our juicy functions. Now that’s quality code!
Once you’ve set up your namespace, you can either add your
properties one by one after declaring the object, as we did above, or
you can include them all inside the object literal, like this:
var TRKR = { namespaces: "cool", boolean: true, pi: 3.14159, css: { "color": "#c0ffee", "top": 0 }, setup: function() { TRKR.one = 1; … }, exclaim: function() { alert("hooray"); } };This code block results in exactly the same namespace object as the one we saw before, and it’s up to you which you prefer. Most of the code you’ll encounter in the remainder of the book will make use of namespacing, whenever it’s appropriate.
this
in a callback, expecting it to point to your
widget namespace, you’ll be unpleasantly surprised: it might be
the global DOM window object
,
or it might refer to something else entirely. For example:
var WIDGET = {}; WIDGET.delay = 1000; WIDGET.run = function() { alert(this.delay); // 1000 … good! $(p).click(function() { alert(this.delay) // undefined! bad! }); };When a
p
tag is clicked, our
event handler runs in a different context than the widget object
itself. So this.delay
will most likely not exist
(and if it does, it’s a different variable to what we wanted anyway!).
There are a few ways we can deal with this, but without being too
JavaScripty, the easiest way is to store the widget’s scope in a variable:
var WIDGET = {}; WIDGET.delay = 1000; WIDGET.run = function() { alert(this.delay); // 1000 … good! var _widget = this; $(p).click(function() { alert(_widget.delay) // 1000 … yes! }); };By setting
_widget
to point to
this
in the context of the
widget, we’ll always be able to refer back to it wherever
we are in the code. In JavaScript, this is called a
closure. The general convention
is to name it
_this
(though some people also use
that
). If it’s used in a
namespacing object, it’s best to name it with an
underscore (
_
), followed by the widget name. This
helps to clarify the scope we’re operating in.
We call “the scope we’re operating in” the
context and there are a few ways
to set it. One is via closures as we saw beforehand, but jQuery also
provides further solutions too.
One more general-purpose approach is the
proxy
method. The proxy is a
little unusual in that you give it a function, and it gives you one
back. Only the returned function will be bound to the context that you
specify, which means no extra variable is required (like
_widget
above) because this
will
refer to the correct scope:
var WIDGET = { delay: 1000, run: function() { alert(this.delay); // 1000 … good! $("p").click( $.proxy(function() { alert(this.delay); // 1000 … yes! }, this); ); } };In this example we wrapped the
click
function in a proxy call. The first
argument was the function we want to run on
click
, and the second is the context
this
.
This might all seem a bit complex, but setting the context can
be fiddly in JavaScript. Just remember: if you have a callback
function that appears to be working incorrectly, debug the
this
property and ensure you are where you think
you are! Keeping the correct context becomes particularly important in
Ajax, and, thankfully, jQuery provides even more ways to help us out,
as we’ll see shortly.
html
action. Whenever we need to
update a content pane, we replace its entire contents with new markup,
like so:
$('#overlay').html("
You have " + cart.items.length + ↵" items in your cart.
");
cart.items
in the
aforementioned example). The format of your data source is likely to
vary widely from project to project: some will be pulled in via Ajax,
some injected directly via a server-side language, and so on.
Obviously those parts of the code will need to be adapted to your
needs.

You have 0 items in your cart.

Total cost is $0

We’ve now added a few container fields to the HTML. When an update of the data is required, we use jQuery to update the text of the containers:
$(this).find('#num-items').text(cart.items.length); $(this).find('#total-cost').text(cart.getTotalCost());This is much nicer than our first attempt: it leaves all the markup in the HTML page where it belongs, and it’s easy to see what the code is doing. There’s one other (very handy) option for managing markup that will be manipulated by jQuery. When you’re working with applications that return a list or grid of results—say, an item list for a shopping cart—you can include an element that acts as a template for each item, and simply copy that element and edit its contents whenever you need to add a new item. Let’s put this into practice by doing a bit of work on the StarTrackr! shopping cart. We’d like to be able to add and remove items using jQuery. The items sit in an HTML
table
, and we’d prefer to avoid writing out
whole table rows in our jQuery code. It’s also difficult to use
placeholders, as there’s no way of knowing in advance how many items
will be in the cart. What we’d like to do is simply prepare empty table
rows, and wait for jQuery to populate them with content.
Our first task is to create an empty row with
display:none;
to act as our template:

 Name	 Qty.	 Total

 Name	 Quantity	 Total.00

template
function accepts a
jQuery selection of a table row, as well as a cart item (an object
containing the item name, quantity, and total price). The result is a
filled-in template ready to be inserted into our HTML document:
So for each new row of data, we need to copy the template,
substitute our values, and append it to the end of the table. A handy
way to copy a selected element is via the
clone
method, which creates a
copy of the current jQuery selection. Once you have cloned an element,
the selection changes to the new element, allowing you to insert it into
the DOM tree:
The template class is removed—because it’s not a template anymore!
We then set up our cart item (in a real example, this data would come
from the server, of course), and then use our
template
method to substitute the data into the
row. Once the substitution is complete, we add the row to the existing
table and fade it in. Our code is kept simple and all our markup stays
in the HTML file where it belongs.
Are there other templating techniques around? Oh yes, dozens! The
methods detailed above are common, and are likely to be all you will
need; but if you find yourself repeating your templating code over and
over, it might be time to check out a more full-featured templating
system.
$.browser
has a few flags for
determining if the current user’s browser is Internet Explorer, WebKit,
Opera, or Mozilla.
$.browser.version
is another
try-not-to-use utility function that reports the current version of the
user’s browser.
Combining these two commands, you can execute conditional code,
like so:
if ($.browser.mozilla && $.browser.version=="9.0") { // Only do this code in Firefox with version 9) }Relying on browser revision numbers and vendor names, though, is just asking for trouble down the road. You want to avoid fixing old code, especially when you could be writing shiny new code, so perhaps it’s time to talk about the alternative to browser sniffing …
opacity
CSS property (for these
browsers, opacity is set using proprietary filter
properties). Before we make use of opacity
in our
code, we could test to see if the user is using Internet Explorer and
act accordingly. But the issue isn’t really Internet Explorer; the
issue is opacity
itself!
To replace browser detection, jQuery has introduced the
$.support
method to report on
the abilities of the user’s browser. Instead of asking, “Is the user’s
browser Internet Explorer?” you should now ask, “Does the user’s
browser support the opacity
style?” like
so:
if (!$.support.opacity) { // Doesn’t support opacity: apply a workaround }The beauty of this approach is that if new browsers emerge in the future without support for the
opacity
style,
or if Internet Explorer suddenly starts
supporting it, your old code will still work perfectly.
There are a dozen or so properties you can test for besides
opacity. For example: $.support.boxModel
returns
false
if a browser is in quirks mode (or just
doesn’t support the box model),
$.support.leadingWhitespace
returns
true
if a browser preserves leading whitespace with
innerHTML
, and so on. Make sure you check the
full list in the documentation should your
project require it.
load
.
The load
method will magically grab an
HTML file off the server and insert its contents within the current web
page. You can load either static HTML files or dynamic pages that
generate HTML output. Here’s a quick example of how you use it:
$('div:first').load('test.html');That’s a very small amount of code for some cool Ajax functionality! This dynamically inserts the entire contents (anything inside the

tags) of the
test.html file into the first div
on the page. You can use any selector to
decide where the HTML should go, and you can even load it into multiple
locations at the same time.

div
underneath the list. This is where we’ll inject the response from our
Ajax calls. The next step is to intercept the links and do some
Ajax:
$('#biographies a').click(function(e) { var url = $(this).attr('href'); $('#biography').load(url); e.preventDefault(); });
href
attribute of the link we clicked on), and pass it on to the
load
function.
This code works perfectly, but injecting the entire contents of
the page turns out to be a bit problematic. Our new content contains

tags, which should really be used
to give the title of the entire page, instead of a small subsection. The
problem is that we don’t necessarily want to load the entire page via
Ajax, just the bits we’re interested in. And once again, jQuery has us
covered …
load
action lets you specify a jQuery
selector as part of the URL string. Only page elements that match the
selector will be returned. This is extremely powerful, as it lets us
build a complete and stand-alone web page for our regular links, and
then pull out snippets for our Ajax links.
The format for using selectors with load
is very simple: you just add the selector string after the filename you
wish to load, separated with a space:
$('#biography').load('computadors.html div:first');The selector you use can be as complex as you like, letting you pick out the most interesting parts of the page to pull in. For our StarTrackr! biographies, we’d like to display the information contained in the description section. We’ll modify the code to look like this:
var url = $(this).attr('href') + ' #description';
div
is loaded in. We will
have a proper look at adding loading indicators very soon, but until
then you can code up a quick-and-dirty solution: just replace the target
element’s text with “loading …” before you call
load
. Again, with your files sitting on your
local machine, you’ll never see the loading text, but it’s good to know
how to do it:
There you have it! Ready to show the client. But since it only
took us 15 minutes, perhaps we should look into the
load
function’s nooks and crannies a little so
we can spruce it up even more.
load
calls if you need to. A common requirement
is to specify some data to pass along to the server; for example, if you
had a search function that returned information based on a query string,
you might call it like this:
$('div#results').load('search.php', 'q=jQuery&maxResults=10');The second parameter passed to
load
is
called
data
. If you pass in a string (as we
did above), jQuery will execute a
GET
request. However, if you instead
pass an object containing your data, it will perform a
POST
request.
Additionally, we can perform processing when a request has
finished by supplying a callback function. The callback function will be passed
three parameters: the response text (the actual data), a string
containing the status of the response (fingers crossed for success—but
here’s where you can gracefully handle errors), and the full response
object itself:
$('div#result').load('feed.php', function(data, status, response) { // Post-processing time! });The
data
parameter, as well as the
callback
parameters within the
data
parameter, are optional. This allows you to use
syntax as simple or as complex as you require when calling
load
.
$('p#description').mouseover(function() { $(this).css('background-color','yellow'); });“There you go,” you say, confidently. But as you refresh the page, you notice that this code fails to work! Why? If you think about it, it makes sense: we’re attaching the event handler to the
p#description
element when the document loads, but
when the document first loads there’s no
p#description
element! We’re adding it dynamically
with Ajax later on. What to do?
We could work around this problem by
only adding the mouseover
event in the callback
function of our Ajax code, but there’s a nicer way: the
on
method. on
lets you
bind a handler in a manner similar to what we’ve been doing so far,
except that it works for all current and future
matched elements. How can it possibly do this? Well, the trick is to add
the handler to a parent element, but only fire for matching
children.
 They were essentially the same as
on
and off
, but
instead of being associated with a container, they worked standalone.
For example, you could add an event handler to any
link
tag placed anywhere at anytime! Unfortunately,
this has some performance side effects; you could end up attaching
hundreds of listeners for every Ajax call. Now we’re forced to
specify a parent container, so only one listener is added.
#biography
element, and applies the callback to any
children that match the p
selector. Hence, the full
form of on
in this case is
$(container).on(event
type, selector, callback)
. If you want to stop the event from
occurring later on, you need to unbind it with the
off
method:
$('#biography').off('mouseover'), 'p';The
mouseover
event handler will be
removed, and no longer be attached to new elements matching the
selector.
on
, you can remove individual functions by
specifying their name as a third parameter to
off
: $('#el').off('click',
myFunction);
. This way, any other handlers that you have
bound to the element will continue to run. In addition, specifying no
selectors or function will remove all click
handlers, while specifying no parameters will remove every handler on
the container.
$.getJSON
. The basic version of this
method accepts a URL and a callback function. The URL is a service that
returns data in JSON format. If the feed is in
JSONP format, you’re able to make requests across domains. As an example, let’s grab a list of posts
that recently mentioned “celebs” on
Facebook:
$.getJSON('http://graph.facebook.com/search?q=celebs', function(result) { alert('Fetched ' + result.data.length + ' items!'); });
var searchTerm = "celebs"; var baseUrl = "http://search.twitter.com/search.json?q="; $.getJSON(baseUrl + searchTerm + "&callback=?", function(data) { $.each(data.results, function() { $('

') .hide() .append('') .append('' + this.from_user ↵ + ' ' + this.text + '') .appendTo('#tweets') .fadeIn(); });
results
array. We iterate over each of the array items using
jQuery’s
$.each
helper method. This
function will execute the function we pass to it once for each item in
the initial array. For each item we create a new div
containing the user’s profile picture, a
link to their profile on Twitter, and the text of the celebrity-related
tweet. The result: a cool Twitter display in just a few lines of
code!
getJSON
calls to
remote servers, you might have noticed that the data returned requires
a bit of work to decipher. You’ll (mostly) have to figure it out for
yourself. Different services have API documentation of varying quality and clarity.
Sometimes it will provide you with examples, but at other times you’ll
be left on your own. One way to examine an API’s data structure is to
type the API URL directly into your web browser and inspect the
resulting JSON directly.
load
function in the jQuery core library source
code, you’d find that sitting snugly at the bottom of the function would
be a call to the $.ajax
method. In fact, if you were
to investigate any of jQuery’s Ajax functions,
you’d find it’s the same with all of them!
All of jQuery’s Ajax functions are simply wrappers around
the $.ajax
method, each designed to provide you
with a simple interface for a specific type of task. By having these
helper methods and additional functionality, jQuery gives you an Ajax
Swiss Army knife that strikes the perfect balance between power and ease
of use.
The $.ajax
method is the heart of
jQuery’s Ajax abilities and is the most powerful and customizable Ajax
method available to us. Being the most complex in jQuery’s arsenal, it
can take a while to conquer, but it’s well worth the effort; this is the
creature you’ll be spending most of your Ajax time with.
$.ajax
method is
more complex than the others we’ve encountered so far, because you need
to spell out everything you want it to do: it will take nothing for
granted. It’s still fairly straightforward to use, though. Here’s a
simple GET
request:
$.ajax({ type: 'GET', url: 'getDetails.php', data: { id: 142 }, success: function(data) { // grabbed some data! } });We specify the request type, the URL to hit, and a success callback wherein we can manipulate the data. Easy. The complexity emerges from the number of possible options you can provide. There are over 20 available options ranging from error callbacks, usernames and passwords for authentication requests, and data filter functions for pre-processing returned information. The majority of the time you’ll only need some of these options, as most common functionality uses just a few. We’ll be putting a bunch of the options to good use in the coming sections and chapters, so they’ll become familiar to you. A full reference of all the options available can be found in Appendix A.
$.ajaxSetup
action:
$.ajaxSetup({ type: 'POST', url: 'send.php', timeout: 3000 });This sets the defaults for further Ajax calls, though you can still override them if you need to. By specifying the common defaults for the page, we can dramatically simplify the code required to actually send a request:
$.ajax({ data: { id: 142 } });This call will send a
POST
request to
send.php, which will time out if it takes longer
than 3,000 milliseconds. Some settings are unable to be set via the
$.ajaxSetup
method;
error
,
complete
, and
success
callback functions, for
example, should be handled with the global Ajax events described in the
next section.
$.getScript
function will load and
execute a
JavaScript file via Ajax. How does this help us out? Well,
if we plan carefully, we can load a minimal amount of our code when the
page loads and then pull in further files as we need them. This is
particularly useful if we require any plugins that have a sizeable
footprint, but regardless of size you should try to delay the loading of
your code until it’s absolutely necessary.
By way of example, let’s load in the
Color plugin we saw in the section called “Color Animation
” in Chapter 3 from the jQuery plugin
repository:
$.getScript('http://github.com/jquery/jquery- color', function() { $('body').animate({'background-color': '#fff'}, 'slow'); });
GET
and POST
requests.
These are simple wrapper functions around the
$.ajax
method, and are more convenient to use;
just select a URL and any data you want to push—and off you go!
The two calls are almost identical, with the only difference being
the HTTP request type:
$.get
will perform a
GET
request and
$.post
will perform a
POST
request. Both requests accept the same
parameters, which (besides the URL) are all optional:
$.get(url, data, callback, dataType); $.post(url, data, callback, dataType);The
data
parameter should contain any data
that needs to be sent to the server. As with the
$.ajax
function, the callback fires on success only, and
will be passed the response data and status. The
type
parameter lets you specify the
data type that will be passed on to the callback function; this can be
xml
, html
,
script
, json
,
jsonp
, or text
, but it’s unlikely
you’ll ever need to use this parameter. Here’s what these methods look
like in action:
$.get("getInfo.php", function(data) { alert("got your data:" + data); }); $.post("setInfo.php", {id: 2, name: "DJ Darth Fader"});Yes, they’re very easy and convenient, but beware! The
$.get
and $.post
methods will only give you data when everything goes hunky-dory—but it’s
a big bad Internet out there, and requests go missing all the time. How
can we be prepared for these situations?
$.get
and $.post
methods were limited in that they
didn’t provide explicit callbacks for handling errors; this made them less
useful for production-level purposes. Thankfully, this has been
rectified by introducing the
Deferred
object in jQuery 1.5.
Deferred
is a utility function that implements a
“promise.” A promise is what it sounds like: it’s a
guarantee to do something in the future. Promises are very useful in
consolidating asynchronous code, to avoid ending up with a tangled
spaghetti mess of callback functions. jQuery’s Ajax functions all use
the Deferred
objects to provide some chainable methods for handling Ajax events.
The chainable methods available to us are
done
,
fail
, and
always
. These methods all
accept a function to execute as a parameter, and can be chained
together as required (you can even call a method multiple times if you
want more than one function to run). Here’s an example of them in
action: $.get("index.html") .done(function(data, status, xhr){ // Runs on success }) .fail(function(data, status, xhr){ // Runs on failure }) .always(function(data, status, xhr){ // Both success and failure });If you’ve used jQuery in the past, these methods might look very similar to the
success
,
failure
, and
complete
callbacks from
$.ajax
. The reason for the change is to take
advantage of the consistency and flexibility offered by the
Deferred
object. These chainable promises are also
available on the regular
$.ajax
function (and indeed, they
are applicable far beyond Ajax—but that’s for later!).
The done
method runs when an Ajax call
successfully completes; the fail
method runs
when something goes wrong; and the always
method runs after the other methods have fired, giving you a chance to
gracefully clean up in either situation. All three methods return the
data from the server, a status message (for example,
success
,
error
, or
timeout
), and a jQuery normalized
XMLHTTPRequest
object.
XMLHTTPRequest
object via Internet Explorer many years before the term “Ajax” was
coined. It is the primary mechanism for doing client-side calls to
the server. jQuery uses its own superset of this object for
working consistently across browsers, and most of the Ajax
callbacks will also include this object; this can be useful for
interrogating response states at a lower level.
For the majority of the time, though, you’ll get everything you
need from the other parameters.
fail
local event and an
ajaxError
global event. The
fail
event can be handled for an individual
request, whereas ajaxError
can handle an error
that occurs in any request. Local events are handled inside the
$.ajax
call, like this:
$.ajax({ url: "test.html" }) .fail(function() { alert('an error occurred!'); });Global events, on the other hand, are generally attached to the DOM node where you’d like to show a response to the user. For instance, you may have a
div
element for
displaying your Ajax error messages:
$("#msg").ajaxError(function(event, request, settings, ex) { $(this).html("Error requesting page " + settings.url + "!"); });Whenever any Ajax call from the page fires an error, this handler will be called. We’re interested in more than just errors, though: there are a bunch of interesting events we can hook into if need be. They’re all structured as in the aforementioned script, and most have a corresponding local and global version, so you can choose which granularity to handle them with. The local
done
event (local) or the
ajaxSuccess
event (global) let us
know when an event has completed successfully. The
always
(local) and
ajaxComplete
(global) events tell
us when an Ajax request has concluded, regardless of its success or
failure. You will only receive either the
success
or the error
event for each request—but you’ll always receive a
complete
or always
event.
The
beforeSend
(local) and
ajaxSend
(global) events let us
react just before an Ajax request is sent into the world. And finally,
the
ajaxStart
and
ajaxStop
global events occur when
an Ajax request fires and no others are already running, and when all
requests are finished, respectively.
We’ll be looking at some practical uses for these events in the
coming examples of Ajax interactivity.
computadors.jpg|night_out.jpg|mr_speaker.jpg|dj_snazzy_jeff.jpgMany web frameworks will now happily return XML or JSON responses for you to consume, but when working with hand-rolled APIs, it’s certainly not uncommon to receive plain-text delimited messages that you’ll have to manipulate and convert into usable data. In this case, we’ll use JavaScript to split the string on the pipe symbol:
data.split('|');
. This will give us an array of image
names to work with.
 The starting HTML is as simple as:
Next, we create a GALLERY
object literal that
will act as our widget namespace. We’ll need to define a few constants:
a selector for the gallery, the URL for our image service, and a delay
time (in milliseconds) for rotating our images. We’ll also stub out a
couple of methods that will form the backbone of the gallery:
var GALLERY = { container: "#gallery", url: "getImages", delay: 5000, load: function() { // Load our data }, display: function(image_url) { // Process the data } };
GALLERY
object itself, because when our Ajax callback
methods run, the scope will be changed and this
will
no longer refer to GALLERY
. We saw in the section called “Scope
” that this is simply a matter of storing the
current scope in a variable, so we can retrieve it later:
var _gallery = this;
.
For the sample code, we’re using a simple text file called
getImages to substitute for our server-side
functionality; it contains an example of the kind of response we’d
expect to receive from the server. Note that for security reasons
Internet Explorer will refuse to execute Ajax requests targeting the
local file system. For testing purposes, therefore, it’s best if you use
another browser. Of course, if you have access to a server, you should
use that instead of a local file!
We could grab our data with the $.get
helper method, but our gallery is going to become more complex rather
quickly, so we’ll be needing the advanced features of the
$.ajax
function. We set up our callback using
the success
option. The callback will split the data
into an array, with each element containing a reference to an
image:
load: function() { var _gallery = this; $.ajax({ type:"get", url: this.url, success: function(data) { var images = data.split('|'); $.each(images, function() { _gallery.display(this); }); } }); }
$.each
utility function is a
nice jQuery way of looping through JavaScript object and array
elements: just pass it the array and a callback function for each
element. The callback function also accepts an optional parameter that
provides you with the index of the element in the original array, if
you need it.
img
tags and append them to the
document. We could do this in the success
callback of our load function, but it will quickly become confusing if
we just throw all our functionality into one big bucket like this. A
neater approach is to separate the loading code from the displaying
code. That’s why we created the display
stub
earlier; it accepts our image URL and adds a new image to the gallery’s
containing element:
display: function(image_url) { $('') .attr('src', '../../images/' + image_url) .hide() .load(function() { $(this).fadeIn(); }) .appendTo(this.container); }
GALLERY.load
; it’s
the regular jQuery load
event. So when the
image tag has finished loading its source, we perform a
fadeIn
.
We’ve set up our gallery widget, but we’ve yet to set it in
motion. All that’s required is a GALLERY.load()
call
once our document is ready:
$(document).ready(function() { GALLERY.load(); });
setInterval
function), a slow network
response might cause some images to be displayed for a very short time
before being replaced by the next set.
We could avoid this by starting the timer after we process the
last set. Perhaps we should start our timer in the
success
callback? Think about that for a second: what would happen if a
request was unsuccessful? Our success
callback would never fire, so we’d never set up our timer and never
reload new images.
The solution is to handle the
complete
event in our
$.ajax
call. We saw in the section called “Ajax Crash Course” that
complete
is called whenever a request concludes,
regardless of success or failure. That seems like a perfect place to
set our timer:
complete: function() { setTimeout(function() { _gallery.load(); }, _gallery.delay); }
setTimeout
function waits for
the delay period to expire before calling our
GALLERY.load
method again. But our display
method simply appends images to the gallery’s containing element, so
every call will just add another stack of images to the page. That’s
going to get out of hand quickly! It will obviously be necessary to
clear the existing images before we add the new ones. Again, there are
few spots where we could do this; the start of the success method is a
good candidate, but we could also experiment with other
places.
For our effect, we’d like to fade out the images slowly as soon
as the next set is requested. This gives us a nice wash of images
fading in and fading out over time. The local
beforeSend
event is our friend here. It gives us a
chance to react before the user’s request is sent off to the
server:
beforeSend: function() { $(_gallery.container) .find('img') .fadeOut('slow', function() { $(this).remove(); }); }
fadeOut
function fires (indicating that the
fade is done), we’ll remove the images from the page. The next set of
images can now happily take their place.
This also solves our progressive enhancement problem. Now that
our gallery widget is removing existing images from the page before
loading new ones, we can safely add a set of static images to our HTML
page for visitors without JavaScript.
If we showed this cool gadget to the client representatives in
its current state, they’d find it hard to believe that it was really
using Ajax, because there’s no animated spinning GIF image! We’d
better add one before they arrive …
img
tag. Here’s the CSS:
.spinner { height: 100%; background: transparent url(../../css/images/spinner.gif) ↵no-repeat center center; }
beforeSend
event, before the Ajax
request is sent off. That sounds like a perfect spot to start our
spinner, so that users will never see a blank, empty page. The new
element stretches over the entire gallery display area, and our
spinner is centered horizontally and vertically:
$('

') .attr('class', 'spinner') .hide() .appendTo(_gallery.container) .fadeTo('slow', 0.6);
complete
handler, to ensure that we
remove the spinner no matter what the outcome of the request.
Preceding the removal with a slow fade seems like a nice touch:
sleep(4);
to wait for four seconds before
continuing. This can help make your testing a bit more
realistic.
.progress { background: #fff url(progress.gif) no-repeat center right; }
ajaxStart
and
ajaxStop
. Remember, the
ajaxStart
method is run when an Ajax request
occurs and no other requests are currently running, and
ajaxStop
is fired after all requests have
finished.
Here are our global handlers:
setTimeout
call
from the complete
event handler. We want the user
to be in control now, instead of the timer.
The first requirement for an endless scrolling component is,
unsurprisingly, a scrollbar. We’ll display one by setting
overflow:auto
on our gallery container and reducing
its width a little.
We’ve added a couple of new methods to our
GALLERY
object: an init()
function for performing some necessary setup code, and a
checkScroll()
method which will be called
whenever the scroll event fires:
init: function() { var _gallery = this; $(this.container).scroll(function() { _gallery.checkScroll(); }); this.load(); },
checkScroll: function() { var gallery_div = $(this.container); if (gallery_div[0].scrollHeight - gallery_div.height() - ↵gallery_div.scrollTop() <= 0) { this.load(); } }
checkScroll
function looks complex
at first, but there’s really little to it. We’re going to be messing
around with the gallery’s containing object quite a lot in this
function, so we store a reference to it to avoid running the same
selector over and over. (This would lead to a significant performance
hit—especially as jQuery will generate lots of events whenever the
user scrolls the scrollbar.)
Next, we do some math to determine whether the scrollbar has hit
the bottom yet. For this we’ll need to break out of jQuery for a bit
and deal with some plain old JavaScript. The
scrollHeight
property is a
nonstandard JavaScript property that’s nonetheless supported by all
major browsers. It tells us the total scrollable height of an element,
unlike height
, which only tells us how much
vertical space the element occupies on the page. In order to access
it, we need to pull the raw DOM node from the jQuery object; the
shortcut for this is [0]
.
By subtracting the element’s height and the current scrolling
position from this scrollHeight
property, we’ll
determine how far from the bottom of the element the user is scrolled
to. If this equals 0
, the scrollbar is resting at
the bottom, and we can load the images.
 Will we start firing off requests willy-nilly? We sure
will! And as the requests start returning, our code will start adding
in images—lots of them! That may be a little inappropriate for our
gallery control, so as a final touch let’s build in a small
safeguard.
We’ll add a Boolean property to our GALLERY
object called running
. When we’re about to load
some data, we’ll first check that the running
variable is set to true
. If it is, this means an
Ajax call is currently underway, and we won’t start
another one: we’ll just return
. If it’s
false
, we’ll go ahead with our call, but first set
it to true
.
Finally, when the request is over (successful or not), we reset
the running
variable to false
,
ready to start all over again:
var _gallery =
this;
. But if you’re comfortable with keeping track of any
scope changes yourself, there is a better way: the
ajax
action has an option called
context
that allows you to set the
scope without needing to keep a local reference:
var GALLERY = { url: "getImages", load: function() { $.ajax({ type:"get", url: this.url, context: this, success: function(data) { // "this" now refers to the GALLERY object! alert('loaded ' + this.url); } }); } };This makes your code neater and shorter, but you have to be aware that the scope is being modified by jQuery in the function callbacks. Other code (such as the
$.each
loop that
displays the images) will still obey the regular JavaScript scope
rules, so for those you’ll have to keep your own reference. The
context
option doesn’t have to be a custom object
as shown previously; it can also be a jQuery or DOM object:
$("
").attr("id", "result").appendTo("body"); $.ajax({ type: "get", url: "GetResults.html", context: $("#result"), success: function(data) { // "this" now refers to the #result element this.html(data); } });
$.ajaxSetup
method and set the
timeout
property. Let’s set ours to 20
seconds:
$.ajaxSetup({ timeout: 20000 });If you have some requests that you expect (or need) to come back faster, you can override the global timeout in the request itself:
$.ajax({ timeout: 4000, … });It’s all well and good to see that your request has timed out—but what are you supposed to do about it? jQuery will give us a fairly good clue as to what went wrong. The
error
event fires whenever something
goes wrong—and this includes when your timeout delay expires.
The handler we specify for this event will receive the
XMLHTTPRequest
object and a status
message that we can use to determine the cause of the error;
timeout
, error
(for HTTP errors, such as everyone’s favorite, 404)
, and
parsererror
(which would indicate
improperly formatted XML or JSON) are values you might see.
You can choose to react differently to different errors, but
it’s typical to simply try the request again. We’ll use the
setTimeout
function to wait for a second before
sending another request (you might need to add some code to make your
server sleep for the duration of the timeout, in order for an error to
occur):
var GALLERY = { … delay: 1000, … load: function() { … var _gallery = this; $.ajax({ type:"get", url: this.url, … error: function(xhr, status) { … setTimeout(function() { _gallery.load(); }, _gallery.delay); } } });
load
operation will fire the
error code, which will call load
again … over
and over until it succeeds. Is that a good idea? Probably not! If it
has failed ten times in a row, it would seem unlikely to suddenly work
the eleventh time around, so at some point we’re going to have to
throw up our hands and say, “That’s it!”
So to finesse this a little bit, we’ll make a couple of changes:
first we’ll add a counter variable, which we’ll call
attempts
. Secondly, we’re going to be modifying the
delay time on each request (we’ll see why soon), so we need to add a
new method to reset everything to the initial values:
var GALLERY = { … delay: 1000, attempts: 3, … reset: function() { this.delay = 1000; this.attempts = 3; }, … }
--
or
++
, the variable will be
decremented or incremented by 1, respectively. This is a handy
shortcut for the
-=
and
+=
operators we’ve already
seen.
attempts
variable. If we make it all the way down
to 0
, we give up retrying. Also, we’ve made a
subtle change to the delay time in the
setTimeout
function: we double the length of
the delay on each attempt to call the load
method. So on the first error we wait for one second, on the second
error two seconds, and if that call also fails, we wait four seconds.
This is known as exponential backoff, and is a
handy way to decrease the frequency of our requests when there’s a
real problem; if a user’s internet connection has dropped, there’s no
sense pinging away madly waiting for it to come back up.
ajaxError
handler to implement some
general handlers for your pages, respond differently to different
types of errors, or provide error messages to let your users know that
something has gone wrong.
<?xml version="1.0" encoding="UTF-8"?> <celebs> <celeb id="421"> <name>Johnny Stardust</name> <image>johnny_200.jpg</image> </celeb> <celeb id="422"> <name>Kellie Kelly</name> <image>kellie_200.jpg</image> </celeb> </celebs>Now that we have our data, we need to update our initial implementation to make use of it. For our first pass we just split the filenames and iterated over each of them using
$.each
. But now our requirements are a little
more complex. We’re receiving XML nodes and we need to extract the
information we require from them. The good news is that jQuery lets us
deal with XML documents exactly the same way we deal with the
DOM!dataType:'xml'
to your Ajax requests, or
specify the correct content-type header
.
find()
to search for nodes by
name, and
next
and
prev
to traverse
siblings:
success: function(data) { $(data) .find('celebs') .children() .each(function() { var node = $(this); var id = node.attr('id'); var name = node.find('name').text(); var image = node.find('image').text(); _gallery.display({'id': id, 'image': image, 'name': name}); }); }
celeb
node and extract its ID, name, and
image URL, which we then combine into an object literal and pass to
our display
method. (This is why JSON is so
handy: it already comes packaged up as a JavaScript object!)
We next have to amend the display
function itself to accept our new data object rather than a simple
text string. Our data
object has some additional
information that we’ll need to access when it comes time to load the
tags: namely an ID, which we’ll pass to the tag service. We’ll store
that value in the img
tag itself,
via the jQuery data
function.
Now that we have access to a celebrity’s name in our data, we
can also fix an
accessibility and standards-compliance issue with our
previous code: we can add an alt
attribute to our images, containing the celebrity’s name:
display: function(dataItem) { $('') .attr({ src: '../../images/' + dataItem.image, alt: dataItem.name }) .hide() .data('id', dataItem.id) .load(function() { $(this).fadeIn(); }) .click(function() { CELEB.load($(this).data('id')); }) .appendTo('#gallery'); }
click
handler. Once we have the ID
we’re ready to move on to the next stage of the image tagging feature:
grabbing and displaying the tag data itself.
We could lump this logic into the GALLERY
widget, but now we’re dealing with a whole new context. Instead, we’ll
separate it out into a new CELEB
widget to keep it
nice and readable:
var CELEB = { url: 'celebs.json', load: function(image_id) { var _celeb = this; $('#details input').attr('disabled', 'disabled'); $.getJSON( this.url, function(data) { $('#details input').removeAttr('disabled'); _celeb.display(data); }); }, display: function(data) { $('#id').val(data.id); $('#name').val(data.name); $('#tags').val(data.tags.join(" ")); } }
$.getJSON
to fetch the data—but
this lacks a beforeSend
or
complete
event handler we can react to in order to
give the user some visible feedback that a request is occurring. What
we’ll do instead is disable the form fields before we send the
request, and re-enable them when the data comes back, using the
attr
method to set the disabled
attribute.
Once the data comes back, we pass it to the
display
function and populate the fields. Yet
another successful Ajax implementation! Of course, with our simulated
JSON response, the celebrity name and tags will be the same no matter
which image you click. But you can try changing the contents of
celebs.json to simulate different server
responses.
serialize
method.

Therefore, if you want to take advantage of this feature, you’ll need
to ensure that your fields are named:
<form> … <input type="text" name="name" /> … <input type="text" name="tags" /> … <input type="hidden" name="id" /> … <input type="button" value="update" /> … </form>
serialize
on a jQuery selection of the form
itself:
var form_data = $("form").serialize();Serializing the data converts it into the typical query string format containing the field name and value separated by ampersands:
name=Kellie+Kelly&tags=b-grade+has-been+rich&id=8And if you’d rather have your data in a more organized format, you can use the oddly named
serializeArray
action. It’s
oddly named as it returns an object (not an array) containing the
key/value pairs of all the form fields.
Let’s take it for a spin:
update: function() { var form_data = $('form').serialize(); … $.post(this.set_url, form_data, function() { $('#status').text('Update successful!'); }); }The
$.post
method is certainly easy
to use! But, as we mentioned earlier, there’s no way of knowing if
something went wrong, so there’s no way we could tell the user about
it. You’re better off replacing that call with our new friend
$.ajax
. That way, as well as adding an
“Update Successful!” message, we can also add error messages and
attach a class
for a spinner
too:
$.ajax({ type: "POST", url: this.url, data: form_data, error: function() { $('#status').text('Update failed. Try again.'). ↵slideDown('slow'); }, success: function() { $('#status').text('Update successful!'); }, complete: function() { setTimeout(function() { $('#status').slideUp('slow'); }, 3000); } });
setTimeout
, which runs in the complete event
handler to slide away the message after a few seconds. To tie this all
together, we simply call this update method when the Submit button is
clicked:
$('#update').click(function() { CELEB.update(); });
console.log
” in Chapter 4). Every Ajax request your page fires will
show up in this display, and you can inspect the contents of each
request, as shown in Figure 6.1.

CLAY PIGEONS Reviewed by Jamie Peck
The story at least gets off to an interesting start, as dim gas station attendant Clay (Joaquin Phoenix) finds himself in hot water with his married sexpot lover (British actress Georgina Cates, doing great Midwestern trash) - her husband learned of their secret hanky-panky and killed himself, but not before making it look like murder and implicating Clay. "Pigeons" takes a turn for the worse, however, around the time the body count eerily starts to rise, a mystery that may or may not be related to a mysterious cowboy named Lester Long (Vince Vaughn) who drifts into the sleepy Montana burg and quickly befriends Clay. The FBI shows up hot on the trail of a serial killer, and it's then - quite late in the game - when the movie finally comes alive.
These flickers of greatness probably have something to do with Janeane Garofalo, whose turn as the cynical agent in charge of the investigation, at first doubting Clay and later helping him, is the best thing about "Pigeons." The precise moment she shows up, you can actually _hear_ the film improving; Garofalo may be her usual acidic, deadpan self, but her talents fit the role snugly and serve as a sardonic contrast when things get too silly. And things get too silly too often - as "Clay Pigeons" chugs towards its conclusion (which is completely ludicrous, by the way), a series of distracting plot holes and contrivances attempt to wrap things up, but all they really do is turn what once was a wildly unpredictable movie into a wildly convoluted mess.
Vaughn and Phoenix don't fare as well as their female co-star, though it's not their fault.  Talk about not knowing what you have - this guy can create fireworks with a role that's up to his juicy comedic rhythms (see "Swingers"). Phoenix plays the straight man to Vaughn's court jester; he's supposed to be our tour guide through this topsy-turvy world, the guy we root for and sympathize with in spite of his flaws. If only David Healy's script hadn't made his flaws so glaring, that might've been possible.

I was asked by BMO Financial Group to create a presentation for their end of year conference to summarize one of their clients' sales with an engaging and friendly presentation. They asked for this specific presentation to be less formal to give the participants a break from the overall serious conference.
I stuck with the Spectrum branding and worked to incporate BMO branding as well. The clients loved the final product and were impressed with how well the information was translated even with the usage of colourful slides - something they were new to.

Police deploy special forces, anti-terrorism squad in Bayelsa
Mike Odiegwu, Yenagoa
The police have sent special forces and anti-terrorism squad to beef up security for the Saturday governorship election in Bayelsa State.
The Deputy Inspector-General of Police in charge of the election, Abdulmajid Ali, said the special forces were among the 31,041 personnel deployed in the state.
Ali said squads from the police mobile force, special protection unit, intelligence response unit, mounted troop, K9 section, air wing and the marine detachment were also sent to the state.
“There shall also be massive logistics mobilisation to support the operations while complementary forces shall be pooled from sister security agencies.
“It must be emphasised that the heavy deployment of all these security operatives is to make the elections a success in the two states and not to intimidate the electorate and the general public”, he said.
He said the Inspector-General of Police directed that all security aides attached to the governor, his deputy and all other public office holders and any other personality involved in the election be withdrawn.
He said the police had the operational capacity to ensure the success of the election adding that they were also aware of threats some misguided elements might attempt to pose during the election
He said: “To such elements, we must sound a note of warning that as a nation, we have had enough electoral violence. We shall not hesitate to identify, isolate and bring to deserved justice any person, group of persons that attempt to threaten the democratic order in Bayelsa”.

I think it should
We could detect this with a linter, right? hs
is not a type class argument (and finite

so there is no way it could ever be inferred, either.
I like the idea of checking this with a linter. It can definitely be done
it does matter that finite

The simplest way to make the linter work is to create a replica of the instance type and try to prove it by apply_instance
this might have false negatives for "transitivity" instances like foo A B -> foo B C -> foo A C
(which should be discouraged)

KSI vs. Logan Paul 2 purses: YouTube stars each guaranteed $900,000
by Mookie AlexanderWith KSI vs. Logan Paul 2 being held in the state of California, we actually get to see their official purses for their respective pro boxing debuts.
Guess what? They are getting a lot of money!
The California State Athletic Commission has put down $900,000 each for both headliners for this six-round cruiserweight bout. If we’re being completely realistic, they’re making a lot more money than that through their personal sponsorships and (at least from KSI’s side) perhaps a cut of the pay-per-view from Sky Box Office in the United Kingdom.
When these two fought in an amateur bout last year, they reportedly sold over a million pay-per-views and made millions of dollars. One can only assume history will repeat itself for Saturday.
As for the actual established boxers on the undercard, WBC lightweight champion Devin Haney is getting a $1 million purse, which is one hell of a feat at just 20 years old. His opponent, the unheralded Alfredo Santiago, is getting a decidedly paltry $90,000, although it might be more than what’s listed given how often foreign fighters have underreported payouts for tax reasons.
WBO super-middleweight champion Billy Joe Saunders’ Matchroom Boxing debut sees him get an official purse of $750,000 against substantial underdog Marcelo Esteban Coceres, whose purse is just $80,000, but much like Santiago, it could be higher (but not much higher) than what’s been listed.
Ronny Rios aside, basically everyone else on the undercard is not even top-50 in their respective weight class.
The full payouts are below:

--- Day 7: Amplification Circuit ---
Based on the navigational maps, you're going to need to send more power to your ship's thrusters to reach Santa in time. To do this, you'll need to configure a series of amplifiers already installed on the ship.
There are five amplifiers connected in series; each one
receives an input signal and produces an output signal. They are connected such that the first amplifier's
output leads to the second amplifier's input, the second amplifier's output leads to the third amplifier's
input, and so on. The first amplifier's input value is 0
, and the last amplifier's output leads
to your ship's thrusters.
O-------O O-------O O-------O O-------O O-------O
0 ->| Amp A |->| Amp B |->| Amp C |->| Amp D |->| Amp E |-> (to thrusters)
O-------O O-------O O-------O O-------O O-------O
The Elves have sent you some Amplifier Controller Software (your puzzle input), a program that should run on your existing Intcode computer. Each amplifier will need to run a copy of the program.
When a copy of the program starts running on an amplifier, it will first use an input instruction to ask the
amplifier for its current phase setting (an integer from 0
to 4
). Each
phase setting is used exactly once, but the Elves can't remember which amplifier needs which phase
setting.
The program will then call another input instruction to get the amplifier's input signal, compute the correct output signal, and supply it back to the amplifier with an output instruction. (If the amplifier has not yet received an input signal, it waits until one arrives.)
Your job is to find the largest output signal that can be sent to the thrusters by trying every possible combination of phase settings on the amplifiers. Make sure that memory is not shared or reused between copies of the program.
For example, suppose you want to try the phase setting sequence 3,1,2,4,0
, which would mean
setting amplifier A
to phase setting 3
, amplifier B
to setting 1
,
C
to 2
, D
to 4
, and E
to 0
.
Then, you could determine the output signal that gets sent from amplifier E
to the thrusters
with the following steps:
- Start the copy of the amplifier controller software that will run on amplifier
A
. At its first input instruction, provide it the amplifier's phase setting,3
. At its second input instruction, provide it the input signal,0
. After some calculations, it will use an output instruction to indicate the amplifier's output signal. - Start the software for amplifier
B
. Provide it the phase setting (1
) and then whatever output signal was produced from amplifierA
. It will then produce a new output signal destined for amplifierC
. - Start the software for amplifier
C
, provide the phase setting (2
) and the value from amplifierB
, then collect its output signal. - Run amplifier
D
's software, provide the phase setting (4
) and input value, and collect its output signal. - Run amplifier
E
's software, provide the phase setting (0
) and input value, and collect its output signal.
The final output signal from amplifier E
would be sent to the thrusters. However, this phase
setting sequence may not have been the best one; another sequence might have sent a higher signal to the
thrusters.
Here are some example programs:
Max thruster signal
43210
(from phase setting sequence4,3,2,1,0
):3,15,3,16,1002,16,10,16,1,16,15,15,4,15,99,0,0
Max thruster signal
54321
(from phase setting sequence0,1,2,3,4
):3,23,3,24,1002,24,10,24,1002,23,-1,23,
101,5,23,23,1,24,23,23,4,23,99,0,0Max thruster signal
65210
(from phase setting sequence1,0,4,3,2
):3,31,3,32,1002,32,10,32,1001,31,-2,31,1007,31,0,33,
1002,33,7,33,1,33,31,31,1,32,31,31,4,31,99,0,0,0
Try every combination of phase settings on the amplifiers. What is the highest signal that can be sent to the thrusters?


For Chinese New Year event, our club designed a game called Nian Battle (打年兽). In the Nian battle, a boss called Nian spawns and the players have to defeat it. The club built the Chinese village that the players have to fight the boss in and Derek coded Nian.
In the Christmas event the club built a map for all of the player's to play on. We hosted the entire event this time and created slides for it. We all had a small group and we all each played with them and told them what to do. What you do is you go into the party games lobby and then you click the axe and then click on the one wool that says Christmas after you click on it you get sent into a game.


TONGUES UNTIED / PARIS IS BURNING A film review by Sarah M. Elkins Copyright 1991 Sarah M. Elkins
I have seen "Tongues Untied" twice so far, once in a local (Rochester NY) theater which shows foreign/independent/classic movies, and once on our local public television station.  I thought it was a moving film, funny and intriguing in some places, sad and beautiful in others, and potentially (not to me, but I can acknowledge the potential) in-your-face offensive in a few places. I thought the part with the snap divas was a howler (loved that "sling snap"), and was fascinated to watch the voguers dancing. The format was a little hard to follow the first time, but I still enjoyed the film, and it's even better the second time.
I did not like PARIS IS BURNING as much, though parts of it were absorbing as well.  "Tongues Untied" reached more of my heart. Perhaps that is because "Tongues Untied" is told from several insiders' positions, as opposed to the "observer/interview" mode of PARIS IS BURNING. However, both of these films have valuable insights. As a white, heterosexual woman, I can attest that these aren"t just "specialized audience" movies. The mixed audiences seemed to agree with me, judging from their reactions.

Dynamic D3.js for scientists
Previously, I wrote up a short tutorial on how to use D3.js with Coffeescript. The examples were simple and in static form, which is what scientists are generally used to regarding figures that are found in papers and presentations. Today, we'll go over the process of making visualization dynamic.


American History X (Reviewed on Nov. 22/98)
Starring Edward Norton, Edward Furlong, Stacy Keach, Avery Brooks, Fairuza Balk, Beverly D'Angelo
It's been two short years since Edward Norton made his his movie debut in "Primal Fear". Despite only appearing in a handful of movies since then, he has proven himself to be one of the best young actors working today. He's got a range that is not often seen in actors these days. In many ways, he's reminiscent of Sean Penn. They both instantly draw an audience in with their charisma, they both have the ability to disappear in their roles, and most importantly, they are not afraid to tackle difficult material.
"American History X" stars Norton as a young skinhead who is living a life he thinks is just.  It all changes, though, when he is arrested for murder and sent to prison for three years. He comes out a changed man, and attempted to get his family out of that life permanently, but discovers his younger brother (Furlong) has taken up the cause.
The movie is told in black and white, and colour. Tony Kaye, the director, lays the symbolism on pretty thick. The black and white is reserved for the flashbacks, which show Norton in his pre-enlightenment days. The lack of colour is supposed to indicate, I guess, that he's not really living like that. It's not until he realizes that racism is wrong, that the colours of the world open up to him. Either that, or it was just a tool to clarify for the audience what was a flashback and what was the present.
The problem with the movie is that it feels more like a series of vignettes, tied together by a recurring character. There's no real sense of plot here. Scenes don't logically lead into one another. Because of this, there's no real flow to the film, which makes it hard for the viewer to really get into it.
My main problem with the film, though, is a scene that comes late in the picture. It's a flashback to Norton's pre-skinhead days.  The way his father reacts to this shows him to be a definite racist. But the part I didn't like, is the way the Norton character so easily accepted what his father said. The way the scene was done, it appeared that these were thoughts Norton had never had. I found it quite hard to believe that an intelligent kid like that would *instantly* accept these racist theories provided by his father, without questioning it at all.  It's like some executives decided that they wanted a definite rationale for why Norton would get involved with the skinheads. Well, it doesn't work.
"American History X" is worth the price of admission simply to witness Norton's incredible performance. I have no doubt, that come Oscar time, he'll be nominated. It's the best performance of his career, and for that reason alone, the film is worth seeing.

For example, if this field is 3, Jenkins will only launch a new instance as long as total number of droplets you run on DigitalOcean (regardless of whether that is for Jenkins or for other purposes) doesn't exceed this number. In this way, even in the worst case of Jenkins starting instances and forgetting about them, you have an upper bound in the number of instances that are concurrently executed.
Leave this field empty to remove a cap (note that DigitalOcean appears to have its own instance cap at 5.)

One of the goodest boys.
You may have heard of him because of the Disney movie, however, unlike the film, he was not a wolfdog. He was a Siberian Husky.
He was, however, a hero, who led a sledding mission across the Alaska territory to deliver vaccines to an isolated town.
Today, you can find a statue dedicated to Balto in New York City, NY, at Central Park.

How Liverpool defeat has impacted Aston Villa relegation odds
Premier League relegation odds latest | Dean Smith's side suffered a 2-1 defeat to Liverpool on Saturday thanks to goals from Andy Robertson and Sadio Mane at Villa Park
by Richard CusackAston Villa slipped to a second Premier League defeat in a row on Saturday, losing 2-1 to Liverpool at Villa Park.
Jurgen Klopp's side needed late goals from Andy Robertson and Sadio Mane to keep up their unbeaten run in the League and ensure they escaped from B6 with all three points.
It wasn't all plain sailing for the Reds, though, with Mahmoud Trezeguet netting his first goal for the club on the 21st minute to set up a nervy finale.
In the end the Villans couldn't hold out and that result leaves them in 16th place in the Premier League table after 14 matches of the season.
The table is starting to shape up now and as far as avoiding relegation is concerned, Villa have 11 points to their name.
That is three more than Southampton in the final relegation spot (18th).
Watford are bottom of the League on five points while, remarkably, just six points separate Villa from Arsenal in fifth place.
Here are the latest relegation odds...
Norwich City - 1/3
Watford - 4/5
Newcastle United - 13/8
Southampton - 2/1
Aston Villa - 12/5
Burnley - 16/5
Sheffield United - 9/2
Brighton & Hove Albion - 13/2
