Spry Data References are pieces of text that represent a column in the data set. They are used within spry:regions and spry:detailregions to present data from the data set in the body of the page.
There are data references from the uses data set and there are built-in data references that are always availalble to the regions. This document will describe these built-in data references.
All data references are denoted by curly braces: {data_reference}. All built-in data references begin with 'ds_', such as {ds_RowID}.
Data References can only be used in the <body> or in data set constructor scripts. They cannot be used in other functions in the head. However, most built-in data references have equivalent functions in the API.
Spry data references are used in a couple ways. First, they are used to provide basic information about the data set, like the total number of records: {ds_RowCount}. It also provides ways for users to specify specific rows in a variety of context. For instance, each row in the data set has a unique number, like the primary key in a data base. This number can always be used to identify that row. There are also references that keep track of row while doing things like looping. For instance, of you sort the data set, there is always a 'first row' of the data set {ds_rowNumber}, but depending on the sort order, the unique information in the first row might change. That data in the first row can have a different {ds_RowID}, depending on the sort.
Spry uses a 0 based counting system.
| Data reference |
Description |
|---|---|
ds_CurrentRowID |
The ID of the current row of the data set. |
ds_CurrentRowNumber |
The row number of the current row of the data set. |
ds_EvenOddRow |
Looks at the current value of ds_RowNumber and returns the string "even" or "odd". |
ds_RowCount |
The number of rows in the data set. |
ds_RowID |
The ID of a row in the data set. |
ds_RowNumber |
The row number of the current row of the data set. |
ds_RowNumberPlus1 |
The same as ds_RowNumber, except that the first row starts at index 1 instead of index 0. |
ds_SortColumn |
The name of the column last used for sorting. |
ds_SortOrder |
The current sort order of the data in the data set. |
ds_UnfilteredRowCount |
The number of rows in the data set before any nondestructive filter is applied. |
{ds_CurrentRowID}
The ID of the current row of the data set.
Each row as an unique RowID. The data set also has a concept of a 'currentRow': The active or selected row in the data set.
The {ds_CurrentRowID} is the RowID for current row of the data set.
This value does not change, even when used within a looping construct.
{ds_CurrentRowID}
{ds_CurrentRowNumber}
The row number of the current row of the data set.
If there is a data set with 10 rows, there is always a first row, or fifth row, no matter what the data of that row is. This data reference returns the row number of the current row.
This value does not change, even when used within a looping, sorting or filtering construct.
{ds_CurrentRowID}
{ds_EvenOddRow}
This data reference returns the word 'even' or 'odd', depending on the current value of the {ds_RowNumber}.
When used in the class attribute, this is useful in creating alternate row styles.
Create CSS classes called '.even' and '.odd' and style as needed.
As this data reference loops through the data set, it will write out 'even' or 'odd'.
<style> .even { background-color: yellow; } .odd { background-color: blue; } </style> ... <tr spry:repeat="ds1" class={ds_EvenOddRow}"> ...
{ds_RowCount}
The number of rows in the data set.
If a nondestructive filter is set on the data set, this is the total number of rows after the filter is applied. Use {ds_UnfilteredRowCount} to display the total number of rows in the unfiltered data.
<div spry:region="ds1">
Total Number of Records: {ds_RowCount}
</div>
{ds_RowID}
The ID of a row in the data set. This ID can be used to refer to a specific record in the data set. It does not change, even when the data is sorted.
This is often used when triggering detail regions with ds.setCurrentRow.
The spry:setrow attribute uses this value behind the scenes to trigger detail regions.
This can be programatically assigned by the developer.
By default, it is a string.
<tr spry:repeat="ds1" onclick="ds1.setCurrentRow('{ds_RowID}');>
Note: We wrap the value in single quotes to deal with preparsing issues with Internet Explorer.
{ds_RowNumber}
The row number of the current row of the data set.
Within a loop construct, this number reflects the position of the row currently being evaluated.
{ds_RowNumber}
{ds_RowNumber}
The same as ds_RowNumber, except that the first row starts at index 1 instead of index 0.
This is used for display purposes. Because Spry uses a zero based counting system, trying to use {ds_RowNumber} would start with 0. Using {ds_RowNumberPlus1} would start with 1, properly reflecting standard counting systems.
{ds_RowNumberPlus1}
{ds_RowNumber}
The name of the column last used for sorting. If the data in the data set was never sorted, this outputs nothing (an empty string).
{ds_SortColumn}
{ds_RowNumber}
The current sort order of the data in the data set. This data reference outputs the words ascending, descending, or nothing (an empty string).
{ds_SortOrder}
{ds_RowNumber}
The number of rows in the data set before any nondestructive filter is applied.
{ds_UnfilteredRowCount}
{function::<function name>}
Invokes the JavaScript function with the specified name during region processing/markup re-generation, the function then has a chance to return a value that will be inserted directly into the markup in place of the data reference.
The signature of the function should be as follows:
function myFunction(region, lookupFunction) { // Code that returns a value. }
When the function is invoked, it will be passed 2 arguments. The first argument is the name of the region that is currently being processed/re-generated. The second argument is a function that can be used to lookup the values of data references. The lookup function is very flexible in terms of the format of the data reference it is given. For example, given a region that is bound to a data set called "ds1", the following calls to the lookup function are equivalent:
var name = lookupFunction("@name"); var name = lookupFunction("{@name}"); var name = lookupFunction("ds1::@name"); var name = lookupFunction("{ds1::@name}"); var name = lookupFunction("ds1", "@name");
<script type="text/javascript"> function FormattedPrice(region, lookupFunc) { // Format the number in the price column so that it // becomes a string that starts with a dollar sign, // and ends with a number that has 2 digits after // the decimal point. return "$" + parseInt(lookupFunc("{dsProducts::price}")).toFixed(2); } </script> ... <div spry:region="dsProducts"> <ul spry:repeatchildren="dsProducts"> <li>{name} - {function::FormattedPrice}</li> </ul> </div>

Quizly - A javascript quiz library made with typescript
As I was building kimchichingu.com I decided that at the end of each section, a simple interactive quiz would help people see if they understood the lesson. Naturally, I set out to find a library for it because why would I make my own? After some googling I couldn’t find one that did what I wanted, most seemed to be more for polling or collecting info than a question answer style academic quiz, so I did what any good programmer would do and made my own!
As I set off to create the library I had to decide on a few things:
- “Do I use jQuery? If so which version do I want to use as a dependency?”
- “How do I want to create the quizes? Json based? Attribute based?”
- “How do I want to distribute it? Git? Npm? Something else?”
All of these were important questions, and I decided to not use jQuery as no one likes libraries that require libraries as a dependency, even though I am using it on Kimchi Chingu. I decided to allow the quizes to be made using json or attributes, and to allow for easy distribution through git and npm. Of course this led to more questions, such as how am I going to build this without worrying if the code works as intended if I want to expand it later or someone wants to open a pull request? I decided that in addition to tests, I was going to use something new and fancy and modern, something that compiles to vanilla javascript, and so I decided on Typescript. I get all the benefits of type checking as well as all the benefits of OOP, including being sure that privates are private, without the hassle of wondering if it is all working correctly.
So to reiterate, a vanilla javascript quiz library, with no dependencies, written
in typescript, that can be used via json or annotations. I’m not going to before
anyone with the gritty details in code as that can be seen in the repository
here. Instead I’ll talk a bit about my
experience building this in Typescript. I would say that the two hardest parts
of writing this in typescript were that javascript doesn’t have true OOP,
such as real private
and protected
access, as well as that when typescript checks
for type mismatches, it also checks the HTMLElement
types by default, whether
you want it to or not.
Javascript prototypical objects and inheritance don’t play well together when
you add protected
and private
into the mix, and also is just kind of clunky and more
of a hacky solution than real classes like in a more OOP language such as Java.
As a result, Typescript classes only check and enforce protected
and private
functions
and fields at compile time, and then all things are actually public
in the
compiled javascript. This caused me hours of pain not knowing this as I was
searching for a reason that my private
fields were public
once compiled.
The second issue, the enforcing of HTMLElement
types by default, was a huge hassle
at the beginning when compiling things as document.querySelect()
returns
a generic HTMLElement
which is expected, and so you have to cast everything. I
would imagine that in a different javascript library that wasn’t so element heavy,
this would not be as much of a hassle, but it definitely was for quizly. I could
have cast all of the HTMLElement
returns to any to avoid having to figure HTMLElement
and it’s family out, but as I would still have to cast just as many elements,
and I would lose all the benefits of type checking that Typescript gives.
I decided that learning which elements extend off of what would be useful as
a web developer in future and also to make a more robust project now.
That’s the simplified story of quizly and how it was built. Would I use typescript again though? I definitely would. The type checking, is invaluable, and the familiarity with a OOP type syntax made coding something of this nature much less painful. So, if you’re looking for a quiz library to use on your site that is light weight, or a not too hard to understand example of typescript, please consider using quizly!

LOOKING FOR RICHARD (1996) A Film Review by Nick Schaden Copyright 1997 Nick Schaden
In "Looking For Richard", director Al Pacino successfully captivates "Richard III" - one of Shakespeare's most famous plays - to the screen. Yes, while many of you out there are probably now emitting an audible yawn from your mouths, listen closely. This isn't just the play reenacted on the big screen ("Julius Caesar"), nor a hip 20th century spin on it ("Romeo & Juliet"). Instead Pacino vouches for a fresh new viewpoint, via documentary. The movie essentially shows the making of the play itself, with actual scenes from the play (in addition to quick interviews with famous actors such as "Kevin Kline") spruced in for flavor throughout.
What makes "Looking For Richard" so great? Al Pacino realizes that 90% of the American public doesn't understand and couldn't care less about Shakespeare's plays. Thus, to play the major roles (Richard III,Clarence,Buckingham,Lady Anne) he recruits famous top name actors, such as Alec Baldwin, Kevin Spacey, Winona Ryder, and of course, Al Pacino himself. In addition, Pacino narrates the documentary himself, carefully explaining the play each step of the way, so we understand at all times what's going on (a common pitfall with other Shakespeare movies). Furthermore, the documentary format makes for a fresh, fun movie, with interesting discussions and interviews to keep the audiences attention. All these elements make for a movie that's entertaining even for Shakespeare haters.
However, for you Shakespeare buffs a likely question is: "Is the actual PLAY good?". Happily, with the high quality of actors in the roles and the wonderful setting, I can say a resounding "yes". The documentary format never hinders what's going on in the play, and rather strengthens it.
However, as with nearly all movies, "Looking For Richard" has it's problems. Ironically, the largest problem is also it's largest strength: the documentary format. While the format is fun, at times it can be slightly confusing to the audience. All in all however, "Looking For Richard" is a great movie, not just for Shakespeare fans, but for everyone.
Nick's Rating: +3 (recommended)
*** Movie rated from -4 (worst) to +4 (best), 0 = average movie ***

I have one pill that was given to me as Ecstasy/MDMA. I had split the pill in half, and swallowed one half with some tap water.
An hour passed and I felt nothing, so I swallowed the other half with some tap water.
A Half hour passes and I still feel nothing. So I undress and lay down in bed and try to go to sleep assuming the pill was bunk.
As I lay in bed I can feel tingling sensation crawling down my back from my shoulders, then a while later I moved my head and it felt incredibly light as if the force of gravity had been reduced. I then noticed the same sensation in my arm and decidied to get out of bed as I may now be feeling the sensation of the drug.
I sat in front of the computer and put on some music with headphones as it was late at night. I didn't notice any auditory distortions, but I felt differently about the music, possibly more emotionally connected.
My limbs feel so easy to move like they had been oiled. I wanted to dance to music but I was so physically relaxed that I found it difficult to hold my body upright.
As the experience intensified I became more physically relaxed to the extent that while sitting in the computer chair I coudln't hold my head upright either, all my limbs were floppy. I ended up laying on the floor with a pillow as I couldn't support my body.
Over all I notice a time dilation through the experience.
At about 3 hours into the experience I went back to bed and went to sleep quicker than I usually do when sober.
I woke up about 7 hours later after a some of the best sleep I've had in a long time. For the next 2 days I feel totally relaxed as I did during the experience but all other effects of the drug are absent. This relaxation makes it difficult to to concentrate and focus on work.

One of the biggest advantages of Ruby, and for many its defining feature, is its ability to easily iterate over objects. It accomplishes this feat by coming pre-packaged with all sorts of easy to use and intuitive methods for manipulate arrays, hashes and other types of data.
Iterating over Hashes/Objects
While Javascript maintains the ability to perform most of these functions, it can't do so with the same level of readability. For example, the good ol' #each loop in ruby looks roughly like this:
hash = {a; 1,b: 2,c: 3,d: 4} sum = 0 hash.each do |key, value| sum += value end
And as long as we're working with hashes (objects in Javascript) the each loop should look pretty similar:
var hash = {a; 1,b: 2,c: 3,d: 4}; var sum = 0; for each (value in hash) { sum += value; }
Iterating over Arrays
But the real problems start showing up when we need to iterate over an array. Javascript does not support easy iteration over arrays with the for each loop. To get such functionality you can use this somewhat messy workaround:
var arr = [1,2,3,4]; var sum = 0; arr.forEach( function(num) { sum += num; });
Notice how this creates a strange nested }); at the end of the loop. The syntax is also inconsistent with the for each loop used for objects. A main reason for using each statements is that it makes the code so much more readable. Notice that to read this new syntax you have to put in extra work. If you didn't know any better, it would look like you were iterating over an array of functions, and where did this num variable come from!?
The better way to iterate over an array is like so:
var arr = [1,2,3,4]; var sum = 0; for (var i = 0; i < arr.length; i++) { sum += arr[i]; }
While this might not look much better, if you step through the code it makes much more sense. First you declare i (traditionally used as an index in for loops). While i < length, you do the following function and then increment by 1. It may not be pretty, but it gets the job done!
Other Javascript Iteration Methods
None of this is to say that Javascript is completely without builtin methods, they are just much more limited and much more verbose. Here's a quick list of other Enumerable-ish methods in Javascript:
- #reduce: acts like an accumulator, great for summing/flattening arrays
- #includes: Checks if an array/object includes the argument
- #map: Like map in Ruby, performs a function on every object and returns a new array.
- #reverse: Reverses the object/array you call this on
- #sort: Sorts stuff!
- #every: Checks if every element passes a certain condition

In the first part of this tutorial I covered how to create a HTML form so that users can input information (using text fields, radio buttons, and so on) and submit that information (using a submit button).
In this second part we need to learn some JavaScript which we can use to test the answers that the user has submitted.
Specifically we’re going to use a JavaScript library called jQuery.
In programming a library is a collection of code that someone else has written and shared.
This is slightly different from the basic code which you can use within a programming language.
For example, in JavaScript you can use particular commands to test or measure things, perform calculation, make and combine things and so on.
A library adds more commands in addition to those basic commands.
Typically, the collection of code brought together in a library solves a particular problem. For example, there are libraries for:
And so on. My book Scraping for Journalists explains how a number of scraping libraries in the Python programming language, for example.
The jQuery library is one of the most widely-used libraries in JavaScript. This is because it pulls together code which allows you to add all sorts of functionality and interactivity to webpages. As the Wikipedia entry for it explains, it makes it:
“easier to navigate a document, select DOM elements, create animations, handle events, and develop … applications.”
To translate some of that: DOM elements are basically elements on a webpage - anything from a heading or a paragraph to a form or an entire article. DOM stands for Document Object Model and refers to the way you can identify elements on a webpage by their position in relation to each other (for example, all paragraphs within an article). This will become clearer as you use jQuery.
jQuery is quite a large library, which means that it can do a lot of different things, but also that there’s lots to discover.
Broadly, however, most jQuery works in a particular way, and it’s useful to explain that before we go further so that things are easier to understand later.
A typical piece of code using jQuery will:
Here’s a simple example of what I mean:
$('h1').hide()
The dollar sign $
turns anything in parentheses after it into a jQuery object. This can then be manipulated using a jQuery method, which is attached using a period.
The example above, then, turns all

tags into jQuery objects, and then hides them using the method .hide()
.
That code selects all

tags by using 'h1'
in parentheses after the dollar sign.
You can make selections by identifying any of the following, in any combination:
'h1'
, 'p'
, 'strong'
, etc. and tags within tags by putting a space between them like so: 'ul li'

would be selected with 'div.biog'
and

would be selected with 'div#nav'
'p:first'
. You can find a list of selectors in the jQuery documentation.These are called selectors.
Tip: Add ids and classes to anything you want to manipulate
The
id
andclass
attributes are used in HTML to identify different elements on a page. Aclass
is normally used for something which appears more than once, whereas anid
is used for something which appears just once.A good example would be a webpage about football team. In that example the navigation and footer might appear only once, but player names, numbers of goals scored, and so on, are likely to appear more than once.
In that situation you might use
id
attributes to identify the navigation and footer like so:

…and the
class
attribute to identify the other elements like so:

Those classes and ids can then be used to style those elements using
CSS - for example player names are always bold and dark grey; the
footer is always yellow text on a black background, with a width of
90% and a height of 20 pixels.But ids and classes can also be used to identify elements with jQuery.
In this case our quiz will end up having more than one question, so we
want to be able to identify each question using a class.
You can do all sorts of things with any element you select using methods. Methods are easy to spot in code because:
The .hide()
method is just one. It is documented on the jQuery website - this is quite jargon-heavy (a good idea is to search for tutorials that use this in practice) but basically it tells you that you can add values in the parentheses to determine how quickly or slowly the item is hidden, and what happens once it is.
The .show()
method is another - it performs the opposite action to .hide()
, not surprisingly.
The navigation on the left side of the jQuery API documentation is the best way to find out about what methods are available. There are methods for effects (such as fading or moving), for events (such as clicking or typing or moving the mouse in a particular area), for styling elements, adding and removing elements, and more.
But now we’ve explained how jQuery works, we need to know what we’re going to need jQuery to do.
Let’s break down the problem we’re tackling here. So far we’ve got a form where the user can select an option and submit it. What next?
To identify what answer the user has selected we’re going to need to identify different parts of the form that they’re using.
Back to our form then. Here is the HTML for a form with three radio buttons:
<form>

Which of the follow is spelt correctly?

<input type="radio" value="They cocked their hats">They cocked their hats

<input type="radio" value="They cocked they're hats">They cocked they're hats

<input type="radio" value="They cocked there hats">They cocked there hats

<input type="submit" value="Submit">
</form>
Because we’re going to use jQuery to manipulate elements on the page it’s a good idea to prepare those elements so they’re as easy as possible to select. Two things we need to think about at this stage:
(Later we’ll need to add more elements if we want to show the results back to the user. But that’s for the next step.)
Let’s simplify the values of each option so it’s easier to identify them later:
<form>

Which of the follow is spelt correctly?

<input type="radio" name="question1" value="their">They cocked their hats

<input type="radio" name="question1" value="theyre">They cocked they're hats

<input type="radio" name="question1" value="there">They cocked there hats

<input type="submit" value="Submit">
</form>
Note that one has the value ‘their’, another ‘theyre’ and the last one ‘there’ - but the text the user sees remains unchanged.
To identify the answers to the questions we need to give them a name
attribute. Below you can see the same HTML as before, but now we have added name="question1"
inside each of the three <input>
tags (i.e. each of the three radio buttons) for that question:
<form>

Which of the follow is spelt correctly?

<input type="radio" name="question1" value="their">They cocked their hats

<input type="radio" name="question1" value="theyre">They cocked they're hats

<input type="radio" name="question1" value="there">They cocked there hats

<input type="submit" value="Submit" id="button">
</form>
The name attribute is used to identify what answer has been submitted - so it’s important to use the same name for all input options for one question.
If we only had one input tag - for example a text field instead of radio buttons - we would only give that one a name attribute.
Further questions would need different name attributes, e.g. name="question2"
for those used to submit the answer for the second question. And so on.
Now you’ve prepared your form, you can start writing jQuery.
We’re going to do this in the same HTML file as the quiz - but you can also create a separate JavaScript file and link to that. This is generally better, especially if you think you’ll need to use it for more than one page.
Your JavaScript should go after the
tag - and before the
tag in the HTML document.
Firstly you need to write a line of code which imports the jQuery library. While you are looking at this on your own computer you should write it like so:

However, once the page is live you should remove the http:
so it looks like this:

Once that line runs you should be able to use jQuery, so do that in the next two lines by opening and closing a script
tag:

The first thing you do in jQuery is what’s called ‘turning the document into a jQuery object‘. This is a bit of jargon: an ‘object’ in programming is anything that you can manipulate using the language. So it basically means turning the document into something that jQuery can work on.
When put between your two script
tags the code to do this looks like so:

Remember that the dollar sign means ‘jQuery’, and anything in parentheses after it is turned into an object that jQuery can work with - in this case, the whole document
.
Now that it can be worked on, it does that straight away with the next bit - .ready
- which will do something when the document is ready (loaded).
What does it do? Everything in parentheses. At the moment there’s nothing in those parentheses - .ready()
- but we’re about to change that by putting something inside them - specifically, a function:

A function does something. What it does is described between curly brackets. Any ingredients it needs is named within curved brackets.
Again, as it stands our function is empty. But all those brackets are getting confusing so you can always format it using indents in a way that makes it easier to understand. These make no difference to how it works:

Now, inside this function we want another one which is only triggered when the submit button is clicked. Here is the code to do that:
$('input#button').click(function() {}
This code does a number of things:
Firstly, it turns the input button into a jQuery object, by again using the dollar sign with that button identified in parentheses after it.
Once that’s done, it uses the .click()
method to specify what happens when that object is clicked.
Why does 'input#button'
identify that particular button? Well here’s the HTML code for the button in question:
<input type="submit" value="Submit" id="button">
The button has an id
attribute with the value ="button"
. The #button
part of our jQuery means id="button"
.
Because it’s within an <input>
tag, we specify that too by putting it before that: 'input#button'
.
So we’ve identified what is going to be clicked, but not yet what will happen when it is clicked. We do that with the click method, described in the jQuery documentation here.
This is added to our selected button with a period as shown previously, like so:
$('input#button').click(function() {} )
When put in our existing script to run when the document is ready, our full code looks like this:

Everything that happens when it is clicked needs to be in those curly brackets, so by the time we’re finished we could have quite a number of lines between the opening curly bracket and the closing curly bracket.
Again, to make that clearer, we’ll split the two curly brackets up and indent the closing one like so (note we also have a closing curved parenthesis too):

Now, to identify what happens when the button is clicked.
Again, if you need help identifying any element search for information on the selectors for different elements in a HTML page.
Now we need to identify what value the user has selected. To make things easier, we’re going to store that value in a variable.
Here’s the code for that:
var answer = $('input:radio[name=question1]:checked').val()
The part before the equals operator creates that variable, called answer
. To the right of the equals operator is the interesting stuff.
The main part there is a selector to identify which radio button has been checked:
'input:radio[name=question1]:checked'
'input'
selects anything in an <input>
tag. :radio
drills down further to select those which are type="radio"
. [name=question1]
selects those which are also name="question1"
:checked
drills down further to select those which are checked or selected.You can find out more about form selectors in jQuery’s documentation for them.
That checked radio button is turned into a jQuery object by being placed within $()
And finally, we grab the value of the checked radio button using the .val()
method. You can find out more on this in the jQuery documentation for the val method. This is within jQuery’s documentation on methods for working with forms generally.
The value is defined in the HTML for each radio button. Here, for example, is the HTML for the third radio button, which has a value of “theyre”:
<input type="radio" name="question1" value="theyre" class="q">
If that radio button is selected when the button is clicked, our jQuery will grab that value. If a different radio button is selected, our jQuery will grab the value for that button instead.
To make this line of code run when the button is clicked, we need to add it in the curly brackets for our click()
function (note the semi colon to indicate the end of that added line):

What happens if no button is selected? In that case there is no value - instead jQuery will register a value of undefined
.
How do we know that? How can we see what the computer sees? That’s where something called the console comes in very handy.
The console.log()
method displays anything in parentheses in the browser’s console.
This is a special feature of modern versions of Chrome, Firefox or Safari which allows you to check what your code is doing without displaying details on the HTML page itself - normally it appears as a separate window below the webpage.
You can access the console in the following ways:
Looking again at the example…
if (answer == "their") { console.log('CORRECT'); }
…this displays the string 'CORRECT'
in the console if the variable answer
is “their”. The user wouldn’t see anything - we’re just using this to show ourselves if the code works before going any further.
You can use the same technique to display things in the console to check how far the code has got.
For example, straight after the
console.log
is particularly useful in displaying variables or calculations that would otherwise be invisible to us, allowing us to see what the computer sees and better troubleshoot any errors.
Straight after creating the variable to hold our user’s answer, for example, we could show that in our console like so:
var answer = $('input:radio[name=question1]:checked').val();
console.log(answer);
Try adding that to your code. By now the whole script - including the line which imports jQuery - should look like this:

Save the page and open it in your browser with the console window open.
Tick one of the answers and watch the console window when you click ‘Submit’…
For a split second the answer will appear - and then disappear. This is because the submitting of the button changes the page. We need to add an extra line to stop this:
return false;
Here’s that when integrated into the function that is run by the click
method:
$('input#button').click(function() {
var answer = $('input:radio[name=question1]:checked').val();
console.log(answer);
return false;
})
}
Again, save your code, and open in your browser or refresh.
Now, when you click on a button the console window should show the answer, and keep it there. And you can see what values each one gives, making the next stage easier.
You might also notice that, to the far right, you’ll see the name of the webpage file and the line of code containing the console.log
method, again helping you if you need to find it.
Now we have that answer stored in the variable answer
that variable can be tested using an if statement in JavaScript.
An if statement has three parts (you can read more about this in w3schools’s tutorials):
if
itself;()
after that;{}
after that.Here, for example, is the code to check if that variable answer
is the string "their"
, followed by empty curly brackets where some sort of action will be:
if (answer == "their") { }
There are various actions we can put there: we can increase a score by a certain amount; we can present the user with feedback (“Correct!” or “Wrong!”); we can hide this question and reveal a new one.
These all involve either creating new variables (e.g. a score) or adding new HTML.
But again we can start by using the console to test our JavaScript.
Here’s an example of doing that as an action to be performed if our test is met:
if (answer == "their") { console.log('CORRECT'); }
This needs be inserted before the return false;
- otherwise we get the same problem with things disappearing. Here’s the code in full:

We can also test if the answer is not “their” by using the NOT operator !=
in an else if
test after the initial if
test:
else if (answer != "their") { console.log('WRONG'); }
Or we could use a simpler else
statement after the initial if
test:
else { console.log('WRONG'); }
This goes into the full code like so:

At the moment this is only displaying information in the console - but we can now adapt this to do anything we want.
To adapt this to change a score we need to do two things:
To create the variable we would write a line of JavaScript like this:
var score = 0;
This needs to be done before the click()
method - otherwise the score will be set at 0 every time the Submit button is clicked.
and to increase that by 1 we would write something like this within the if
statement testing for the correct answer:
score++ ;
The ++
operator will increment any number by one.
Here are those two pieces of code - setting the variable and adding to it if the answer is correct - along with a third to show the result in the console, within the context of the full code:

Now, how to tell the user whether they were correct or wrong? That’s the subject of the next and final part.

Quick use
If you just want to play around ASAP, the quickest way is to import the entire library, either as a module in your JS:
import Color from "https://colorjs.io/dist/color.esm.js";
To be able to use import
statements in your JS, your <script>
element needs type="module"
Color
as a global variable, the classic way, just include the following script in your HTML:
<script src="https://colorjs.io/dist/color.js"></script>
You can also add .min
right before the .js
extension to get a minified file.
Via npm
Run:
npm install colorjsio
Custom bundle
Or, create a custom bundle that is tailored to your needs.
This is a work in progress and doesn't fully work yet. Right now it can generate import statements, but not an actual bundle.
[join(importStatement where include, '\n')]
[if(format = "iife", 'window.Color = window.Color || Color;', '')]
// Re-export
export default Color;
Download
How to use your custom bundle
The following assume your downloaded file is in the same directory as the JS/HTML file using it. If not, adjust the path accordingly.
If using client-side, include in your page via:
<script src="color.js" type="module"></script>
Or, include in your JS via:
import Color from "./color.js"
To be able to use import
statements in your JS, your <script>
element needs type="module"

Demo-ware is great for getting your head around a new topic but we’ve been seeing Entity Framework demo-ware for five years now. You’re probably not writing an application to manage your music collection or composing yet another Twitter client. You need to build complex applications related to the Core-Domain in the enterprise and therefore you need to know how to integrate Entity Framework in serious and decoupled architectures. In this session we look at breaking up your domain models following the Domain-Driven Design (DDD) Bounded-Context pattern, splitting and defining entities and aggregates properly in the different domain models, and implementing repositories and units of work that are relevant to EF DbContext and DbSets, in the data persistence infrastructure layer. We also cover how to build automated tests around code that involves Entity Framework, whether they be integration tests or strictly unit tests where Entity Framework seems to get in the way.


Logan Paul vows to "contest the commission" after being docked points in KSI defeat
The American YouTube star was left raging after the decision cost him victory in the main event fight from Staples Center in Los Angeles
by Aaron Flanagan, https://www.mirror.co.uk/authors/aaron-flanagan/Logan Paul has been left furious by the referee's decision to controversially dock him points in his defeat to KSI.
The American YouTuber was two points in the fourth round after being found to have punched KSI after he had been knocked down.
It turned out that the two points were crucial, as he lost 56-55 on the third and final judges' decisive scorecard.
One judge scored the fight 56-55 in favour of Paul, the other scored it 57-54 in favour of KSI, before the final and decisive card ensured the split decision result.
After paying tribute to KSI and congratulating him for his victory, Paul fumed at the official for the costly decision.
"I thought it was a legitimate knockdown," Paul said. "I didn't get a warning.
"I got two points taken away from me and that's the reason I lost tonight. I would love to contest the commission because I think I should have got a warning. I don't think it was fair at all."
Paul was then asked whether he wants to fight KSI for a third time.
He said: "I'd love to fight KSI again, these are the best moments of my life.
"I just want to say fair play to KSI, you are one of the toughest people I know and I wish you the best. I can talk trash but it's all for show."
However, KSI ruled out a third fight, claiming: "It's done."
KSI added: “I'm on to the next thing. You should do MMA. You should fight CM Punk.
“I moved around quite a bit. I got him a lot to the body, to slow him down.
“I felt good and I was happy. It's different and I took some big shots.”


Out top tips
for travel in Japan
Most subway lines in Tokyo start at around 5 am and last trains depart at around midnight. In Tokyo the rush hour is roughly 7.30am-9.30am and 5.30pm-7.30pm. There are not many night buses, so taxis are the only option in the early hours. Subway services are a little less frequent on weekends and public holidays. There are things you can do if you miss the last subway and have to wait until the first train the next morning.
PASMO/SUICA can be used to travel on normal bus lines in the Tokyo metropolitan area as well as some inter-city express buses and airport shuttle buses.
Taxi fares have basic charges.
Taxis can be taken at the taxi stand.
Smoking is prohibited inside taxis.
There are taxis that accept credit cards.
Taxi’s door on the left side will open and close automatically.
Visitors to the city can use the small wheeled electric bicycles by purchasing a one-day pass and bicycles can be returned on any of the numerous ports in each ward.
The type of medical institution you need differs between time of use,
if it is an emergency, and with the level of severity.

When should I use xml:lang
and when should I define my own element or attribute for passing
language values in an XML document schema (DTD)?
Sometimes documents contain or include different types of natural language content. Other times they need to store a natural
language value as data or meta-data about something external to the document. Because these different applications use similar formats, schema
designers are sometimes confused about when they should use xml:lang
and when to define their own language-related element or attribute.
For example, in XHTML 1.0, there is an hreflang
attribute and also an xml:lang
(or lang
attribute, in the case of HTML) for the content of the a
element:
Click for German
The xml:lang
attribute describes the language contained by the a
element ("Click for
German"), while the hreflang
attribute is meta-data, in this case describing the language of some content external to this
Web page.
xml:lang
Content directly associated with the XML document (either contained within the document directly or considered part of the document
when it is processed or rendered) should use the xml:lang
attribute to indicate the language of that content. xml:lang
should be reserved for content
authors to directly label any natural language content they may have.
xml:lang
is defined by XML 1.0 as a common attribute that can be used to indicate the language of any
element's contents. This includes any human readable text, as well as other content (such as embedded objects like images or sound files) contained
by the element in which it appears. The xml:lang
value applies to any sub-elements contained by the element. It also applies
to attribute values associated with the element and sub-elements (though using natural language in attributes is not best practice). The
value of the xml:lang
attribute is a language tag defined by BCP 47.
For example, here is xml:lang
on an element t
:
<t xml:lang="en">
This is some text contained by the 't' element. The use
of the xml:lang attribute indicates the language so that, for
example, the correct font could be applied when rendered or
the correct spell-checker could be used when proofing the
document. If we didn't have xml:lang, we might have problems
with embedded content, such as the phrase
C'est la vie, which is in another language.
</t>
This example shows how xml:lang
applies to an attribute:
<para>Il faut utiliser SOAP</para>
When the language value is really an attribute of or metadata about some external content, then xml:lang
is
not an appropriate choice. In these cases you want to store language information, but the language doesn't refer to the content of the XML document
(or included content, such as images, which are processed as part of the document) directly. In this case you should define an element or attribute
of using a different name and not use the xml:lang
attribute. The value of the element or attribute should use BCP 47, just like xml:lang
.
Some examples of this might include:
a
in XHTML) pointing to a version of this document in another
languageThe reason you would choose to create your own element (or attribute) is to convey the language as a value (as part of a data
structure or as metadata about an external document) rather than to indicate the language of a specific piece of content. Avoiding the use of xml:lang
to describe external language values avoids creating problems for content authors who need to label content for
text-processing purposes.
For example, an XML document might look like this:
<item type="DVD">
<title xml:lang="fr">Cyrano de Bergerac</title>

<runningTime value="137" />

<dialogue>en</dialogue>

<subtitles track="1" language="zh-Hant" />

<subtitles track="2" language="zh-Hans" />
</item>
In this example, the xml:lang
attribute conveys information about the natural language of text appearing in
this document. The dialogue
element and the language
attribute of the subtitles
element are defined in the XML document schema and convey a natural
language value associated with these items. For example, it conveys the information that the subtitles on Track #1 are written or displayed in
Traditional Chinese (zh-Hant
).
It's important to remember that xml:lang
has scope: lower-level elements inherit the language attribute. This can
be used to identify the language for a lot of content (without having redundant language tags on every element). For example, it is good practice to
put xml:lang
into your html
element at the start of an XHTML document and only reuse it where the
language of the text changes. For more information, see the article Language tags
in HTML and XML.
Applying xml:lang
to an attribute is problematic: there is no way to:
identify more than one language in the title
attribute

Bonjour

separate the language used in the attribute from that used in the element.
English
Note that the three schema languages (XML DTD, XML Schema, and RELAX NG) differ with respect to the question of whether a user has to
define xml:lang
before using it as an attribute. Specifically:
XML DTDs require that any element that uses xml:lang
as an attribute must declare it in the DTD
XML Schema requires that the xml namespace be declared and imported before using xml:lang
(and other xml namespace values)
RELAX NG predeclares the xml namespace, as in XML, so no additional declaration is needed.
BCP 47, Tags for the Identifying Languages Specifies how to use language tags in xml:lang
values.
Language tags in HTML and XML Describes how to use language tags.

it is just part of the chaos


This page gives a guide how to configure and tune applications that use large state.
For Flink applications to run reliably at large scale, two conditions must be fulfilled:
The application needs to be able to take checkpoints reliably
The resources need to be sufficient catch up with the input data streams after a failure
The first sections discuss how to get well performing checkpoints at scale. The last section explains some best practices concerning planning how many resources to use.
The easiest way to monitor checkpoint behavior is via the UI’s checkpoint section. The documentation for checkpoint monitoring shows how to access the available checkpoint metrics.
The two numbers that are of particular interest when scaling up checkpoints are:
The time until operators start their checkpoint: This time is currently not exposed directly, but corresponds to:
checkpoint_start_delay = end_to_end_duration - synchronous_duration - asynchronous_duration
When the time to trigger the checkpoint is constantly very high, it means that the checkpoint barriers need a long time to travel from the source to the operators. That typically indicates that the system is operating under a constant backpressure.
The amount of data buffered during alignments. For exactly-once semantics, Flink aligns the streams at operators that receive multiple input streams, buffering some data for that alignment. The buffered data volume is ideally low - higher amounts means that checkpoint barriers are received at very different times from the different input streams.
Note that when the here indicated numbers can be occasionally high in the presence of transient backpressure, data skew, or network issues. However, if the numbers are constantly very high, it means that Flink puts many resources into checkpointing.
Checkpoints are triggered at regular intervals that applications can configure. When a checkpoint takes longer to complete than the checkpoint interval, the next checkpoint is not triggered before the in-progress checkpoint completes. By default the next checkpoint will then be triggered immediately once the ongoing checkpoint completes.
When checkpoints end up frequently taking longer than the base interval (for example because state grew larger than planned, or the storage where checkpoints are stored is temporarily slow), the system is constantly taking checkpoints (new ones are started immediately once ongoing once finish). That can mean that too many resources are constantly tied up in checkpointing and that the operators make too little progress. This behavior has less impact on streaming applications that use asynchronously checkpointed state, but may still have an impact on overall application performance.
To prevent such a situation, applications can define a minimum duration between checkpoints:
StreamExecutionEnvironment.getCheckpointConfig().setMinPauseBetweenCheckpoints(milliseconds)
This duration is the minimum time interval that must pass between the end of the latest checkpoint and the beginning of the next. The figure below illustrates how this impacts checkpointing.
Note: Applications can be configured (via the CheckpointConfig
) to allow multiple checkpoints to be in progress at
the same time. For applications with large state in Flink, this often ties up too many resources into the checkpointing.
When a savepoint is manually triggered, it may be in process concurrently with an ongoing checkpoint.
Before Flink 1.3, an increased number of network buffers also caused increased checkpointing times since keeping more in-flight data meant that checkpoint barriers got delayed. Since Flink 1.3, the number of network buffers used per outgoing/incoming channel is limited and thus network buffers may be configured without affecting checkpoint times (see network buffer configuration).
When state is asynchronously snapshotted, the checkpoints scale better than when the state is synchronously snapshotted. Especially in more complex streaming applications with multiple joins, Co-functions, or windows, this may have a profound impact.
To get state to be snapshotted asynchronously, applications have to do two things:
Use state that is managed by Flink: Managed state means that Flink provides the data
structure in which the state is stored. Currently, this is true for keyed state, which is abstracted behind the
interfaces like ValueState
, ListState
, ReducingState
, …
Use a state backend that supports asynchronous snapshots. In Flink 1.2, only the RocksDB state backend uses fully asynchronous snapshots. Starting from Flink 1.3, heap-based state backends also support asynchronous snapshots.
The above two points imply that large state should generally be kept as keyed state, not as operator state.
The state storage workhorse of many large scale Flink streaming applications is the RocksDB State Backend. The backend scales well beyond main memory and reliably stores large keyed state.
Unfortunately, RocksDB’s performance can vary with configuration, and there is little documentation on how to tune RocksDB properly. For example, the default configuration is tailored towards SSDs and performs suboptimal on spinning disks.
Incremental Checkpoints
Incremental checkpoints can dramatically reduce the checkpointing time in comparison to full checkpoints, at the cost of a (potentially) longer recovery time. The core idea is that incremental checkpoints only record all changes to the previous completed checkpoint, instead of producing a full, self-contained backup of the state backend. Like this, incremental checkpoints build upon previous checkpoints. Flink leverages RocksDB’s internal backup mechanism in a way that is self-consolidating over time. As a result, the incremental checkpoint history in Flink does not grow indefinitely, and old checkpoints are eventually subsumed and pruned automatically.
While we strongly encourage the use of incremental checkpoints for large state, please note that this is a new feature and currently not enabled
by default. To enable this feature, users can instantiate a RocksDBStateBackend
with the corresponding boolean flag in the constructor set to true
, e.g.:
RocksDB Timers
For RocksDB, a user can chose whether timers are stored on the heap (default) or inside RocksDB. Heap-based timers can have a better performance for smaller numbers of timers, while storing timers inside RocksDB offers higher scalability as the number of timers in RocksDB can exceed the available main memory (spilling to disk).
When using RockDB as state backend, the type of timer storage can be selected through Flink’s configuration via option key state.backend.rocksdb.timer-service.factory
.
Possible choices are heap
(to store timers on the heap, default) and rocksdb
(to store timers in RocksDB).
Note The combination RocksDB state backend / with incremental checkpoint / with heap-based timers currently does NOT support asynchronous snapshots for the timers state.
Other state like keyed state is still snapshotted asynchronously. Please note that this is not a regression from previous versions and will be resolved with FLINK-10026
.
Passing Options to RocksDB
Predefined Options
Flink provides some predefined collections of option for RocksDB for different settings, which can be set for example via
RocksDBStateBackend.setPredefinedOptions(PredefinedOptions.SPINNING_DISK_OPTIMIZED_HIGH_MEM)
.
We expect to accumulate more such profiles over time. Feel free to contribute such predefined option profiles when you found a set of options that work well and seem representative for certain workloads.
Note RocksDB is a native library that allocates memory directly from the process, and not from the JVM. Any memory you assign to RocksDB will have to be accounted for, typically by decreasing the JVM heap size of the TaskManagers by the same amount. Not doing that may result in YARN/Mesos/etc terminating the JVM processes for allocating more memory than configured.
This section discusses how to decide how many resources should be used for a Flink job to run reliably. The basic rules of thumb for capacity planning are:
Normal operation should have enough capacity to not operate under constant back pressure. See back pressure monitoring for details on how to check whether the application runs under back pressure.
Provision some extra resources on top of the resources needed to run the program back-pressure-free during failure-free time. These resources are needed to “catch up” with the input data that accumulated during the time the application was recovering. How much that should be depends on how long recovery operations usually take (which depends on the size of the state that needs to be loaded into the new TaskManagers on a failover) and how fast the scenario requires failures to recover.
Important: The base line should to be established with checkpointing activated, because checkpointing ties up some amount of resources (such as network bandwidth).
Temporary back pressure is usually okay, and an essential part of execution flow control during load spikes, during catch-up phases, or when external systems (that are written to in a sink) exhibit temporary slowdown.
Certain operations (like large windows) result in a spiky load for their downstream operators: In the case of windows, the downstream operators may have little to do while the window is being built, and have a load to do when the windows are emitted. The planning for the downstream parallelism needs to take into account how much the windows emit and how fast such a spike needs to be processed.
Important: In order to allow for adding resources later, make sure to set the maximum parallelism of the data stream program to a reasonable number. The maximum parallelism defines how high you can set the programs parallelism when re-scaling the program (via a savepoint).
Flink’s internal bookkeeping tracks parallel state in the granularity of max-parallelism-many key groups. Flink’s design strives to make it efficient to have a very high value for the maximum parallelism, even if executing the program with a low parallelism.
Flink offers optional compression (default: off) for all checkpoints and savepoints. Currently, compression always uses the snappy compression algorithm (version 1.1.4) but we are planning to support custom compression algorithms in the future. Compression works on the granularity of key-groups in keyed state, i.e. each key-group can be decompressed individually, which is important for rescaling.
Compression can be activated through the ExecutionConfig
:
Note The compression option has no impact on incremental snapshots, because they are using RocksDB’s internal format which is always using snappy compression out of the box.
In Flink’s checkpointing, each task produces a snapshot of its state that is then written to a distributed store. Each task acknowledges a successful write of the state to the job manager by sending a handle that describes the location of the state in the distributed store. The job manager, in turn, collects the handles from all tasks and bundles them into a checkpoint object.
In case of recovery, the job manager opens the latest checkpoint object and sends the handles back to the corresponding tasks, which can then restore their state from the distributed storage. Using a distributed storage to store state has two important advantages. First, the storage is fault tolerant and second, all state in the distributed store is accessible to all nodes and can be easily redistributed (e.g. for rescaling).
However, using a remote distributed store has also one big disadvantage: all tasks must read their state from a remote location, over the network. In many scenarios, recovery could reschedule failed tasks to the same task manager as in the previous run (of course there are exceptions like machine failures), but we still have to read remote state. This can result in long recovery time for large states, even if there was only a small failure on a single machine.
Task-local state recovery targets exactly this problem of long recovery time and the main idea is the following: for every checkpoint, each task does not only write task states to the distributed storage, but also keep a secondary copy of the state snapshot in a storage that is local to the task (e.g. on local disk or in memory). Notice that the primary store for snapshots must still be the distributed store, because local storage does not ensure durability under node failures and also does not provide access for other nodes to redistribute state, this functionality still requires the primary copy.
However, for each task that can be rescheduled to the previous location for recovery, we can restore state from the secondary, local copy and avoid the costs of reading the state remotely. Given that many failures are not node failures and node failures typically only affect one or very few nodes at a time, it is very likely that in a recovery most tasks can return to their previous location and find their local state intact. This is what makes local recovery effective in reducing recovery time.
Please note that this can come at some additional costs per checkpoint for creating and storing the secondary local state copy, depending on the chosen state backend and checkpointing strategy. For example, in most cases the implementation will simply duplicate the writes to the distributed store to a local file.
Task-local state is always considered a secondary copy, the ground truth of the checkpoint state is the primary copy in the distributed store. This has implications for problems with local state during checkpointing and recovery:
For checkpointing, the primary copy must be successful and a failure to produce the secondary, local copy will not fail the checkpoint. A checkpoint will fail if the primary copy could not be created, even if the secondary copy was successfully created.
Only the primary copy is acknowledged and managed by the job manager, secondary copies are owned by task managers and their life cycles can be independent from their primary copies. For example, it is possible to retain a history of the 3 latest checkpoints as primary copies and only keep the task-local state of the latest checkpoint.
For recovery, Flink will always attempt to restore from task-local state first, if a matching secondary copy is available. If any problem occurs during the recovery from the secondary copy, Flink will transparently retry to recover the task from the primary copy. Recovery only fails, if primary and the (optional) secondary copy failed. In this case, depending on the configuration Flink could still fall back to an older checkpoint.
It is possible that the task-local copy contains only parts of the full task state (e.g. exception while writing one local file). In this case, Flink will first try to recover local parts locally, non-local state is restored from the primary copy. Primary state must always be complete and is a superset of the task-local state.
Task-local state can have a different format than the primary state, they are not required to be byte identical. For example, it could be even possible that the task-local state is an in-memory consisting of heap objects, and not stored in any files.
If a task manager is lost, the local state from all its task is lost.
Task-local recovery is deactivated by default and can be activated through Flink’s configuration with the key state.backend.local-recovery
as specified
in CheckpointingOptions.LOCAL_RECOVERY
. The value for this setting can either be true to enable or false (default) to disable local recovery.
Limitation: Currently, task-local recovery only covers keyed state backends. Keyed state is typically by far the largest part of the state. In the near future, we will also cover operator state and timers.
The following state backends can support task-local recovery.
FsStateBackend: task-local recovery is supported for keyed state. The implementation will duplicate the state to a local file. This can introduce additional write costs and occupy local disk space. In the future, we might also offer an implementation that keeps task-local state in memory.
RocksDBStateBackend: task-local recovery is supported for keyed state. For full checkpoints, state is duplicated to a local file. This can introduce additional write costs and occupy local disk space. For incremental snapshots, the local state is based on RocksDB’s native checkpointing mechanism. This mechanism is also used as the first step to create the primary copy, which means that in this case no additional cost is introduced for creating the secondary copy. We simply keep the native checkpoint directory around instead of deleting it after uploading to the distributed store. This local copy can share active files with the working directory of RocksDB (via hard links), so for active files also no additional disk space is consumed for task-local recovery with incremental snapshots. Using hard links also means that the RocksDB directories must be on the same physical device as all the configure local recovery directories that can be used to store local state, or else establishing hard links can fail (see FLINK-10954). Currently, this also prevents using local recovery when RocksDB directories are configured to be located on more than one physical device.
Task-local recovery assumes allocation-preserving task scheduling under failures, which works as follows. Each task remembers its previous allocation and requests the exact same slot to restart in recovery. If this slot is not available, the task will request a new, fresh slot from the resource manager. This way, if a task manager is no longer available, a task that cannot return to its previous location will not drive other recovering tasks out of their previous slots. Our reasoning is that the previous slot can only disappear when a task manager is no longer available, and in this case some tasks have to request a new slot anyways. With our scheduling strategy we give the maximum number of tasks a chance to recover from their local state and avoid the cascading effect of tasks stealing their previous slots from one another.
Allocation-preserving scheduling does not work with Flink’s legacy mode.

Theory and Examples¶
This page describes basic concepts of one-dimensional ground response analysis and the usage of transfer functions. For more details, the user is encounged to read [Kra96].
One-dimensional ground response analysis¶
Evaluation of ground response is one of the most common tasks in geotechnical earthquake engineering. Ground response analyses are used to predict ground surface motions, to develop design response spectra, to evaluate potential for liquefaction, and to determine earthquake induced loads to super structures. As seismic body waves travel through different geologic units, they are reflected and refracted when reaching boundaries. One-dimensional ground response analyses are based on the assumption that all boundaries are horizontal and that the response of a soil deposit is predominantly caused by SH-waves propagating vertically from the underlying bedrock.
Transfer function¶
An important method for ground response analysis is based on the use of transfer functions, which determine how each frequency in the bedrock (input) motion is amplified, or deamplified, by the soil deposit. A transfer function may be viewed as a filter that acts upon some input signal to produce an output signal. For one dimensional site response analysis, the transfer function can be used to calcualte various response parameters, such as acceleration, velocity, displacement, shear stress, and shear strain, under an input motion parameter such as a bedrock acceleration. Because this method relies on the principle of superposition, this analysis is limited to the analysis of linear systems.
The basic steps are as following:
Obtain the Fourier series for the applied motion using the Fast Fourier Transform (FFT).
Multiply the Fourier series by the appropriate value of the transfer function at each frequency to obtain the output Fourier series.
Express the output Fourier series in the time domain using the inverse FFT.
The greatest amplification will occur approximately at the lowest natural frequency, also know as the fundamental frequency. For a uniform soil profile the fundamental frequency is
where \(v_s\) and \(H\) are the shear wave velocity and thickness of the soil profile.
The period of vibration corresponding to the fundamental frequency is called the characteristic site period:
Evaluation of Transfer function¶
Within the profile, both upward and downward travelling waves exist due to reflection at each layer boundary (refraction is ignored in 1D assumption). When the bedrock is rigid, any downward travelling waves in the soil are completely reflected back toward the ground surface. Thus all elastic wave energy is trapped in the system. An elastic bedrock, on the other hand, only reflects part of the downward travelling waves that reach the soil-rock interface; part of the elastic wave energy is transmitted through the interface and lost from the system. This is a form of radiation damping and it causes the free surface motion amplitudes to be smaller than those for the case of rigid bedrock. The fraction of reflected waves depends on the complex impedance ratio, \(\alpha_z\), that is defined as,
where \(G^*,\,k^*,\,v_s^*\) are the complex shear modulus, complex wave number, and complex shear wave velocity, respectively.
[Kra96] presents details about the evaluation of transfer functions for four different cases by varing the assumptions for soil and bedrock, respectively. These cases are replicated in the figures below using this tool:
Unifom, undamped soil on rigid rock¶
Uniform, damped soil on rigid rock¶
Unifom, damped soil on elastic rock¶
Layered, damped soil on elastic rock¶
Rigid bedrock vs. elastic bedrock¶
If the within motion is known, a rigid bedrock condition should be used for estimating the surface motion. In this tool, a rigid based condition can be approximately represented by increasing the stiffness (shear wave velocity and/or density) of the bedrock. When including the elastic bedrock a bedrock motion should be used instead. A bedrock motion can be obtained from the decombolution of an outcrop (surface) motion.


Hilton to open Canopy property in Paris’ Latin Quarter
by Mark CaswellHilton has announced plans for a second Paris property under its Canopy lifestyle brand.
The 150-room Canopy by Hilton Paris Quartier Latin will be located on rue Lacepede, close to the city’s Jardin des Plantes.
Expected to open in 2022, the hotel will be housed with a new seven-storey building, combined with a renovated historical mansion which features an “Eiffel-style industrial roof”.
Facilities will include a restaurant, bar, tea room and fitness centre, and the hotel will also feature a “vegetated façade with climbing plants”, as well as a ground floor garden.
The property will join the Canopy by Hilton Paris Trocadero which is scheduled to open in 2020.
The Canopy brand was launched in 2014, and there are currently just nine properties open, including the brand’s first mainland Europe hotel which opened in Zagreb in November 2018.
Canopy London City was originally set to open in 2018, but is now expected to be unveiled next year.
Commenting on the news Patrick Fitzgibbon, senior vice president, development, EMEA, Hilton said:
“With the first property opening near Trocadero in 2020, introducing the second Canopy by Hilton hotel to Paris, the first on the left-bank, is a significant milestone in our French expansion plans.
“Already one of the world’s most visited cities, Paris is enjoying a surge in tourism, recording close to 40 million visitors in 2018, with demand set to increase.
“Canopy by Hilton Paris Quartier Latin creates the ultimate Parisian experience. It is perfect for exploring this charming neighbourhood, and its central location is ideal for those who want to search out Paris’ cultural sites, gastronomic adventures and all that this remarkable city of light has to offer.”


Bash script to fix double braces for Jekyll Scholar
This bash script corrects double braces in bib

THE ART OF AMALIA
Reviewed by Harvey Karten Avatar Films Director: Bruno de Almeida Writer: Bruno de Almeida, Frank Coelho Cast: Amalia Rodrigues, John Ventimiglia (narrator), David Byrne (introduction)
Just eighteen days before the world premiere screening of Bruno De Almeida's non-fiction pic "The Art of Amalia," we received word that Julia Child has been awarded the Legion of Honor, the highest honor that France can bestow. If you know the French, you can believe that this medal is rarely awarded to a foreigner. How does this current event relate to Senhor de Almeida's film? Amalia Rodrigues, Portugal's best-known singer, was similarly given that award. For Ms. Rodrigues the award was perhaps more distinctive since, after all, Julia Child devoted her life to promoting French cuisine in the U.S., while Amalia Rodrigues merely performed several times in Paris. Obviously Amalia is a performer worth knowing about. Bruno de Almeida, who lives in New York, does a remarkable job bringing her to life in his non-fiction piece--a ninety-minute work edited down from a five-hour miniseries that ran on European TV, one which the prestigous online magazine Film Threat calls "One of the year's best documentaries." "The Art of Amalia" is crammed so full of a variety of song excerpts--count 'em, sixty-seven--that one wonders how much additional information de Almeida could have delivered by the unedited version.
"The Art of Amalia" is notable in part for two reasons. One is that the documentary does not go into her personal life, which should be considered nobody's business unless a performer wants particularly to expose her affairs to a broad public. The other is that de Almeida avoids the soul-killing mistake made by so documentarians of making an audience sit through a plethora of talking heads--nieces, uncles, nephews, friends, all gassing about the subject. There's really only one talking head, one person sitting and discussing the subject of the film between shots of actual performances, and that's Amalia herself.
Now, nobody can accuse one of the world's great singers of false modesty. Discussing her art, she settles poised with her long, flaming, dyed red hair, talking without apologies about how she almost literally brought down the house in one concert in Italy, how she is adored wherever she goes, how she sang her heart out to the wild applause of her fans. That's OK. Why pretend? We see proof of her accomplishments by watching her in old newsreels, clips of studio pressings, and best of all live concerts in Paris, Rome, Naples, Los Angeles, Libson, Tokyo New York and Rio among other cities. We see how she guides huge throngs into clapping to the rhythms of her more upbeat songs.
While we watch Amalia sing in Italian (Tarantella), in French (Aie Mourrir Pour Toi), and in English (The Nearness of You), her specialty is fado--Portugal's answer to Spain's flamenco in that fado songs are passionate, sad, moody, or to coin the oxymoron used in this film, sweet sadness. While flamenco has been embraced by the world to a much greater extent, popularized in America by Brooklynite Jose Greco, fado is a genre that has relied for its popularity on just one person, the subject of this documentary.
Despite her extravagance of language during her interview appearance, she is (as Internet critic Brian Matherly points out for the Jacksonville Film Journal) "overwhelmed at times" when on stage or presented with medals such as Portugal's Great Cross of the Order of St. Iago de Espada, and in Mathherly's view does not emulate "the actions of an egotistical star who revels in her spotlight and immense fame." In fact, she tell us that despite her prominence and fortune, she was never a happy person and in one instance-- during a trip to New York in 1985--she had planned to end her life (because of a tumor she had developed, not because of her experiences in the Big Apple). But tumor removed, she continued her 50-year career, surprisingly enough losing little of her vocal qualities even into her seventies.
Bruno de Almeida has done a splended job of bringing together historical film clips from as far back as 1920, interspersing scenes from performers who influenced Ms. Rodrigues such as Fred Astaire. Sadly, she died one week before the completion of the film, so that our only chance now to hear her would be through her many, many recordings and this exceptional film.

(version: development)
With Cedille 1.1, we have a version of Cedille that provides familiar higher level concepts for datatypes like datatype declarations, constructors, and pattern-matching (histomorphic) recursion. Cedille 1.1 elaborates these down to Cedille Core, a pure type theory without primitive datatypesl This accomplishes a major goal in the roadmap of Cedille 1.0. Future directions are somewhat up in the air at present. One avenue likely to be developed in 2019 is automatic subtyping, which will make certain examples with datatype notations more succinct. The following items are still on the agenda:
We also plan to continue incorporating high-level syntax for advanced datatype features into Cedille, although exactly which might be up next is currently not determined.


Technology in Education
Technology is an amazing resource to use in education that can help educators introduce new content, review content, assess and monitor students' understanding of concepts, and much more. However, it's important to remember that technology is just another tool in the educators' toolbox.
When designing instruction it's important for educators to determine what they want their students to learn, explore, and/or be able to do before deciding which tools will help them to be effective and efficient in helping students learn.

| An example White should not move c4 to c5, since it will create a 5 in-a-row which does not capture any stone. However, White may move b5-c5, making a 3 in-a-row and remove the black stone at e3 removing a black attack (the move e3-f3). |
This game is probably a relative of Yote.
