The component approach
by Wilson Page / @wilsonpage
- Today I'm going to talk about a front-end approach I've been taking in recent years
- I **call this approach** 'the component approach'
- **Next:** A bit of background...
Break pages into chunks...
everything's a component
- Essentially we devide our pages into pieces
- We don't have some parts of the page as components and some not.
- Everything is a component.
Component?
Definition
Encapsulation
Communication
Performance
Styling
Responsive
- Physical components
- 'FruitMachine'
- It's not always obvious.
- Aides encapsulation, untangled achitecture
- Portabile and water-tight.
- Responsive: range of screen sizes.
"A part that combines with other parts to form something bigger"
- Let's have a look at an example of real life component, and what we can learn from it.
- Starter motor that you'd find in the bonnet of your car
- Input => electric current. Output => Turning cog
- Black box, implementation is hidden. **It's encapsuldated**.
- Components manufactures all over the world
- A lot can be learnt from this established manufacturing process
- Let's take a look at a more familiar component.
<video>
- If you've used the video-element,
- you've already worked with components.
- Great example of how components should be designed.
- Proof that designing in the right way can make components usable in infinite ways.
Public API
video.play()
video.pause()
video.load()
- The interface that we use to control the component
Events
'ended'
'error'
'playing'
'progress'
'waiting'
- Emits numerous events
- We can listen to an react when the component tells us something has changed
Markup - HTML
Styling - CSS
Behaviour - JS
- 3 Ingredients that form a component:
- Markup: Structure and content
- Styling:
- Behaviour:
Encapsulated
Controllable
Informative
Configurable
Reusable
- The characteristics of a good component:
- Complexity hidden
- Give the user control
- Notify us when things change
- Shouldn't attempt to work perfectly out of the box
- Create as many as we like
You don't need a framework to get started with components
- Infinate ways to define a 'component'
- You don't need a framework to get started
var MyComponent = function() {
this.el = document.createElement('div');
};
MyComponent.prototype.render = function() {
this.el.innerHTML = 'hello world';
};
var component = new MyComponent();
component.render();
document.body.appendChild(component.el);
- Instantiable 'class', we can create as many as we need.
- Root element DOM handle, marks the boundary
- Render injects HTML into the root element
Why use a framework then?
Consistent codebase
Interoperability
Abstract repetition
- Consistent codebase
- Familiarity across team
- Without guidelines, on large teams, things can get messy
- Enable interoperability
- Consistent API means components can work together
- With a basic known API, we can write plugins
- Abstract repetition
- Tackle problems centrally
FruitMachine
- At the Financial Times we wrote FruitMachine
- Provided us with a consistent way to define and assemble view components
'A lightweight library for defining and assembling UI components'
var MyComponent = fruitmachine.define({
name: 'my-component',
template: function() {
return 'hello world';
}
});
// Usage
var component = new MyComponent();
component.render();
component.appendTo(document.body);
- Here is an example of a basic view
- template is just a function
- So why write our own library...?
Why did we write our own?
- We wanted something fully tailored to our needs.
- We wanted to know the code-base inside out.
- But perhaps it was just the 'control-freak' nature of our team
- Let's tak a look at what our requirements were...
'Retro-fittability'
- Large codebase, application rewrite is unfeasible.
- New components has to sit alongside old legacy UI.
- Had to be light, un-costly to experiment
- Gradually spread across code-base
- FruitMachine now renders every view in the FT web-app
Declarative layouts
- Not just defining the components, but also the assembly.
{
"module": "layout-a",
"children": {
"slot1": {
"module": "header",
"model": {
"title": "My Web App"
}
},
"slot2": {
"module": "big-story",
"model": {
"title": "Story title",
"body": "Story body..."
}
},
...
}
}
var layout = fruitmachine(layoutJSON);
layout
.render()
.appendTo(document.body);
{{{ slot1 }}}
{{{ slot2 }}}
- The template for the 'layout-a' module
Server-side rendering
- Wasn't a immediate requirement
- Didn't want FM to limit what was possible in the future
- **Next:** Advantages of server-side rendering?
Crawlable content
Faster 'time to content'
Provide a <noscript>
experience
- Search engine spiders
- Don't have to wait for JavaScript
- Support a basic experience, and progressively enhance website to app.
- What did this mean for fruitmachine...?
Client & server share definitions
All views rendered as strings
Client enhances server generated HTML
- This mean that all views had to be rendered a strings
- Without a DOM we render HTML strings, **fast**.
- Sent down the wire, **Brought to life** on the client
Encapsulation
- What does 'encapsulation' mean...?
'The condition of being enclosed (as in a capsule)'
Why is encapsulation good?
Promotes reuse
- When components don't depend on **outside conditions**
- They can be dropped anywhere
- Makes reusing chunks of UI easy
Decoupled from application
- **Untangle** our code-base
- Making applications easier to **maintain**.
Lower barrier to entry
- By reducing required scope of understanding
- New devs can dive straight into an app
- need only understand the small component their task concerns
- Make changes without fear of breaking other unrelated parts
Improve sense of ownership
- Devlopers **care more** when they feel **ownership/accountability**
- Ownership can get lost as **teams/apps grow**
- Making developers owners of components can help boost lingering enthusiasm
- **Next:** Quote captures the problem that encapsulation solves...
"The more tied components are to each other, the less reusable they will be; and the more difficult it becomes to make changes to one, without accidentally affecting another"
- Rebecca Murphey, jQuery Fundamentals.
- Enough about why it's good.
- **Next:** Let's walk through an example of a component that **isn't encapsulated**, and see how we can **improve it**.
// Component Code
var MyComponent = function() {
var myElement = document.querySelector('.my-element');
this.el = document.createElement('div');
this.el.style.height = myElement.clientHeight + 'px';
};
// Application code
var component = new MyComponent();
document.body.appendChild(component.el);
- Spec: Match height of 'my-element'
- This component is not encapsulated
- document is out of scope
- **Next:** Let's improve this...
// Component Code
var MyComponent = function(options) {
this.el = document.createElement('div');
this.el.style.height = options.height + 'px';
};
// Application Code
var myElement = document.querySelector('.my-element');
var height = myElement.clientHeight;
var component = new MyComponent({ height: height });
document.body.appendChild(component.el);
- Tightened up the scope, by injecting dependencies.
- Easier to unit-test.
- Let's summarise what we've learnt...
Treat each component as a 'mini-app'
Pass/inject outside dependencies
Ignorance is bliss
- In-penetrable boundary
- This take me onto my next topic...
Communication
- Well architected 'communication' is critical to keeping components encapsulated
- We need to be able to talk to our components, and our components need to be able to talk to us.
- Communication is two-way
API & Events
- Our application talks to its components using API
- Our components talk to our application using events
- FruitMachine components all have event logic mixed in
Your app should control its components, never the reverse.
- Let's take a look at an example of how good use of communication can 'decouple' components from application
var app = require('app');
function MyImage(options) {
this.el = document.createElement('img');
this.el.src = options.src;
this.el.addEventListener('click', app.showGallery);
};
// App code
var MyImage = require('my-image');
var image = new MyImage({ src: 'image.jpg' });
- Component depends on our application
- Means can't be reused
- Circular dependencies:
- Can break builds
- Tangled code-base
- It's tempting to call app code; it's so close, don't!
function MyImage(src) {
var self = this;
events(this); // <=
this.el = document.createElement('image');
this.el.src = options.src;
this.el.addEventListener('click', function() {
self.fire('click'); // <=
});
}
var MyImage = require('my-image');
var image = new MyImage({ src: 'image.jpg' });
image.on('click', showGallery); // <=
Events are awesome!
...but know when they're not appropriate
// Don't describe intention
this.fire('showgallery');
// Describe what happened
this.fire('click');
// ... and let the app decide what to do
image.on('click', showGallery);
API to cause something to happen
Events to signal something has happened
Fire from where the event happened
Communication rule of thumb:
- Use API to cause something to happen
- Use events to signal something has happened
- Events should be fired where they happened
Bubbling
- If you're familiar with DOM events you'll be aware of the concept of 'bubbling'
- Is when events rise up through the layers of the DOM
- We introduced bubbling events to FruitMachine:
- Decouple application controllers from components
- Layouts of arbitrary components
- Example...
var image = layout.module('my-image');
if (image) {
image.on('click', showGallery);
}
FruitMachine introduced event propagation to nested components
layout.on('click', showGallery);
layout.on('click', 'my-image', showGallery);
- Good communication helps solve tangled, circular dependencies.
- The application entry point is the trunk
- Modules are required, that require other modules... This forms branches.
- Circular dependencies occur when a module 'a' => 'b' => 'a'.
- The equivalent of a branch rejoining the trunk.
Performance
- We have a dreamy component architecture, but is it still fast?
With hidden implementation, we forfeit some control
- By hiding implementation details inside components takes away some control from the application.
Components have full access to the DOM (which can be dangerous)
- The DOM is shared by all our components.
- DOM is **tempramental**, we need to be nice to it.
Layout is expensive. Do it as little as possible.
- Layout is the operation a browser performs to calculate the size and position of each element.
- We found layout to be our biggest performance bottleneck.
componentA.innerHTML = 'Component A'; // <= Write
componentA.clientHeight; // <= Read (reflow)
componentB.innerHTML = 'Component B'; // <= Write
componentB.clientHeight; // <= Read (reflow)
componentC.innerHTML = 'Component C'; // <= Write
componentC.clientHeight; // <= Read (reflow)
- This example illustrates the problem we were having
'Layout thrashing'
How can we prevent it...?
FastDOM avoids layout thrashing, by batching DOM reads & writes.
fastdom.write(function() {
componentA.innerHTML = 'Component A'; // <= Write
fastdom.read(function() {
componentA.clientHeight; // <= Read
});
});
fastdom.write(function() {
componentB.innerHTML = 'Component B'; // <= Write
fastdom.read(function() {
componentB.clientHeight; // <= Read
});
});
- Wrap DOM write operation in `fastdom.write`.
- And each DOM read operation in `fastdom.read`.
- FastDOM schedules the work to be run on the next animation frame.
- It runs them in two batches, 'reads', then 'writes' to avoid thrashing.
'Layout' now occurs only once per frame
- Layout now only occurs *once*, per frame.
- Essentially FastDOM gives us an asynchronous, non-blocking DOM.
Layout boundaries
wilsonpage.co.uk/introducing-layout-boundaries
- One of the other performance boosts I cam across last year.
- A 'layout boundary' is a DOM node that can limit the scope of layout.
- When the DOM changes, browser doesn't have to layout on elements *outside* the boundary.
- NEXT: Let's have a look at the performance gains...
- Timeline profile 'post-render' layout
- Took 5.6ms
- Size of the layout tree 1814
- Layout scope/root is 'document'
- No layout boundaries were encountered
- NEXT: Let's look at the same operation with a layout boundary...
- Duration dropped from 5.6 to 1.6ms
- Layout tree reduced: 1814 -> 607 nodes
- Layout scope/root is our layout-boundary
300% improvement in layout performance
- On mobile, this make a big difference!
- Duration: 3.45ms
- 'layout tree size': 996 nodes
- Layout is about 5 times faster (0.6ms)
- 'layout tree size' has reduced (234 nodes)
- The 'layout root' has changed
Improved animation frame-rate
Not be display inline
or inline-block
Not have a percentage height
value.
Not have an implicit or auto
height
value.
Not have an implicit or auto
width
value.
Have an explicit overflow
value (scroll
, auto
or hidden
).
Not be a descendant of a <table>
element.
- What defines a layout boundary?
- Some of that sounds complicated...
.my-component {
width: 100%;
height: 100px;
overflow: hidden;
}
- A percentage or pixel width
- A pixel height
- And overflow set to 'hidden'
- The **root element** of many of our components
- If this is still confusing, Paul Lewis made a tool called 'Boundarizr' which helps identify 'Layout Boundaries'.
- NEXT: Let's summarise...
Try a tool like FastDOM to harmonize thrashing components
Experiment with 'layout boundaries' to improve post-render layout performance
Styling
- We've got our components on the page and they're fast.
- Now we need to style them.
- Our main two goals are:
- **Portability**
- **Preventing leakage**
CSS is tricky to tame
'Componentising' makes things easier
In big applications:
- CSS is tricky to tame...
- ...but 'Componentising' makes things easier
- You could end up with 100s of files
- Relax, SASS will concatenate for us.
- Our directory structure is flat.
- All components created equal.
- Let's talk about our 'styling objectives'.
Maximise portability
Minimise leakage
- Portable: Drop a component anywhere
- Leakage: Prevent our styling accidentally leaking onto other components.
- Soon 'Shadow DOM' and 'Scoped stylesheets' will help
- NEXT: Now we must depend on 'pure discipline'
Pure discipline
- Let's look at different approaches to styling a simple component
- Address some of the issues frequently seen in the wild.
Headline
Body content
article { /* styles */ }
h1 { /* styles */ }
p { /* styles */ }
- This looks like bad news:
- Will affect every other `artice`, `h1` and `p`
- CSS is like coding with `window` globals in JS.
- In JS we have closures; in CSS there is no concept of scope...
- NEXT: So we need to fake it...
Headline
Body content
.my-component { /* styles */ }
.my-component .title { /* styles */ }
.my-component .body { /* styles */ }
.title { color: red; }
- Nothing complex, **namespacing** gives basic 'scope'.
- Styles will no longer leak.
- But: What if someone writes this... (fragment)
- Doesn't protect against poorly written styles by other.
- Using common class names leaves us open to attack.
- NEXT: We must protect ourselves from this carelessness!
Headline
Body content
.my-component {}
.my-component_title {}
.my-component_body {}
- There is now a very high probability our classes are **unique**, and we have prevented both leakage, and being leaked upon.
- Using prefixed classes negates the need for parent selectors
- Shorter selectors
- Portable selectors
- **NEXT:** Let's summarise...
In a responsive application, components need to change their appearance
@media
covers styling, but sometimes we need more...
Same markup
Different appearances
Different behaviours
var ArticleList = fruitmachine.define({
name: 'article-list',
breakpoints: {
'column': {
setup: function() {},
teardown: function() {}
},
'row': {
setup: function() {},
teardown: function() {}
},
'small': {
setup: function() {},
teardown: function() {}
}
}
});
Detecting breakpoints
- Inspired by article by Jeremy Keith
@media(orientation: landscape) {
.article-list:after { content: 'column' }
}
@media(orientation: portrait) {
.article-list:after { content: 'row' }
}
window.addEventListener('resize', function() {
var style = getComputedStyle(articleList.el, ':after');
style.content; //=> 'column'|'row'
});
We could now map JS breakpoints to CSS breakpoints
- It worked and it was relatively simple
- What I didn't know...
- I'd just implemented our biggest performance bottleneck.
window.getComputedStyle()
...kinda expensive!
- When run several times per second, per component
- I'd created a monster.
- I needed to kill it before my team found out what I'd done
- Back to the drawing board...
window.matchMedia
- I had known for a while matchMedia could tell you whether a media-query matched the current document.
- What I didn't know was that you could listen for changes
var media = window.matchMedia('(min-width: 500px)');
media.addListener(function(data) {
alert('matches: ' + data.matches);
});
- It seemed perfect, so I set about work
var ArticleList = fruitmachine.define({
name: 'article-list',
media: {
'orientation: landscape': 'column',
'orientation: portrait': 'row',
...
},
states: {
'column': {
setup: function() {},
teardown: function() {}
},
'row': {
...
}
}
});
- `media` property to map a media-query to a 'state'
.my-component.column {
/* 'column' styling */
}
.my-component.row {
/* 'row' styling */
}
- Moved all media-queries into JavaScript and instead used classes to style the different states.
- Ensured styling and behaviours always remained in sync.
Can you re-use the same component with different breakpoints?
- Default breakpoints aren't always appropriate
- How can we re-use the same component with a different breakpoint configuration?
var peach = new Peach({
media: {
'orientation: landscape': 'column'
}
});
- Override media map per instance
- CSS breakpoints can't be easily overridden, JS can.
- I've reversed the media map.
Conclude
- Let's dilute what we've spoken about
- Some key points...
Tight scope to promotes reuse and reduces tangled code-bases
Use configuration to maximise usage
Expose a public interface
Use events to react to changes
Timeline your apps to keep an eye out costly DOM work
Smart CSS selectors for rock solid styling
Look to existing components (like <video>
) for inspiration
window.matchMedia
for 'behavioural' breakpoints
- Keep components tightly scoped. Promote reuse, reduce tangled code-bases
- Make components configurable to maximise their usage
- Expose a public interface so components can be controlled
- Use events to react to changes inside components
- Timeline your apps to keep an eye out costly DOM work
- Use smart CSS selectors for rock solid styling
- Look to existing web-components, like video, for inspiration
- `window.matchMedia` can help with 'behavioural' breakpoints
"The secret to building large apps is never build large apps . Break your applications into small pieces . Then, assemble those testable, bite-sized pieces into your big application" - Justin Meyer, JavaScriptMVC
If we're going to get better as an industry, we should look at lessons already learnt. Manufacturing an entire car from scratch is no longer competitive, parts are **sourced** from all over the world, then **assembled in one place**.
Imagine a web of **trusted**, **shareable** components at our **fingertips**. More people, building higher quality applications, with ease. If we **embrace this change**, if build this platform, **we can make the web win**.

LINK VALIDATION ¶
Work in progress
Imagine a researcher in the need of integrating data on publications, authors and education institutions. Wrongly executing this integration task could mean, for example, assigning the h-index of author A to author B or wrongly saying that author A is affiliated to an institution he has never been involved with. Hardly any matching algorithm returns only perfect results. In light of this, to reach a solid investigation result, it is of importance to support human validation once links have been created and optionally improved.
1. Uncertainty vs. Vagueness¶
Referring to propositions (the sky is blue, the bottle is full, the tomato is ripe…) in logic, the use of degree of (un)certainty, belief or confidence is to emphasise an evaluation of the assignment of a truth value to a proposition which may or may not qualify as vague (“the tomato is ripe”). For example, how certain are we in saying that the proposition “the tomato is ripe” is true? As [Lukasiewicz2008] illustrates, saying that “John is a teacher” and “John is a student” with respectively 0.3 and 0.7 as degrees of certainty is roughly saying that “John is either a teacher or a student, but more likely a student”. However, the vague statement “John is tall” with the assignment of 0.9 as degree of truth can be roughly translated as “John is quite tall”.
The transition from assigning boolean truth values {0, 1} to assigning continuous values in the unit interval [0, 1] to propositions (event) is clearly the change from classical logic to fuzzy logic which is in the modelling paradigm of many-valued Logics. The latter truth space (unit interval) is motivated by the presence of vague concepts in a proposition, making it hard or sometimes even impossible to establish whether the proposition is completely true or false [Lukasiewicz2008]. Now, whatever truth value is assigned to an event, sometimes, one wonders about the chance that the even will happen (Probability) or might happen (Possibility)[Kovalerchuk2017].
Degrees of Truth is not to be confused with the Degrees of Certainty / Confidence as the latter is not an assignment of truth value as opposed to the former, but rather an evaluation of a weighted proposition (proposition with an assigned truth value) regardless of its truth value space ({0, 1} or [0, 1]).
1. Validation and Links’ Context¶
- intrinsic properties
- the purpose or task for which the links are used.
2. Voting Strategies¶
In the Semantic Web, the standard semantic OWL/DL interpretation of identity between two resources entails full equality , i.e. they are necessarily the same and share all their properties. Such semantic applies independently of context and therefore no validation or dispute apply since that semantic does not take any of it into account: things are either the same or they are not. [Idrissou 2017]
In real life problems, the equality between resources may depend (i) not only on their intrinsic properties (ii) but also on the purpose or task for which they are used. For example, an organisation A and B are the same in context 1 but not not the same in context 2.
Instead of the rigid owl:sameAs standard semantics, if an alternative semantics is considered where context is taken into account, then things can be the same or not depending on the context that applies. Moreover, within a common context there can still be divergences when, for example, there is not enough information for reaching a correct (indisputable) outcome. In other words, for the same identity link, multiple “truths” (multiple possible interpretations) can co-exist once we agree on the context in which these “truths” are cast.
As a result, the Lenticular Lens tool allows for a single link to be both (i) established within a context and (ii) validated countless times, and then, by continuity, it allows for a collection of links (linkset or lens) to have various validations by different users. Even thought this is a desirable feature, before using the links for integration one needs to make a decision about their validity. This brings us to what we denote as Voting which is the merging of Validations sharing the same context.
The Lenticular Lens tool provides five ways for merging validations. These include: Accepted Once, Rejected Once, Majority, Disputed, Weighted Experts. and Highest Ranking Experts. In the next section, we discuss the aforementioned options.
2.1 Consistent Validations¶
This is the best scenario. A link has been validated several times with the same outcome, meaning not once a contradiction has occurred. The validation is consistent and therefore remains as it is.
2.2 Disputed Validations¶
Disputes occur when a link has been validated several times but with contradicting truth statements (inconsistently). For example, when a links has been ACCEPTED three times but REJECTED twice. In this scenario, we follow a simple protocol:
-
The link with contradicting validations is flagged as DISPUTED.
-
The following options can be chosen for reaching an agreement:
Majority. Consider the link as ACCEPTED if it has been accepted more times than being rejected, otherwise consider the link as REJECTED.
Rejected Once. Consider the link as REJECTED if it has been rejected at least once.
Accepted Once. Consider the link as ACCEPTED if it has been accepted at least once.
Weighted Experts. In this situation, a weighted sum is performed within each voting group (ACCEPTED vs REJECTED). The group with the highest weighted sum gets to cast its vote.
Highest Ranking Experts. Deciding on how to merge several validations on the basis of the authority with the highest rank is also possible. The decision to accept or reject the link is solely made by the highest ranking expert. It is easy to see here that there can be still disputes among highest ranked experts. In this case, the majority among experts applies.
-
No matter the option, in the event of a tie, the link is REJECTED unless stated otherwise by the user.

First off: I'm young. I'm 16 years old. Road Trip was made for people my age and people my age will enjoy it. If you're not a teenager, you probably won't like this movie. There is a reason too - it wasn't made for you to like it. Now on to the review.
In my mind, raunchy films such as American Pie, the recently released Road Trip, and (to some extent) the "adult" comedy There's Something About Mary will always be compared with the original gross-out comedy classic National Lampoon's Animal House. One of the few movies to literally take my breath away with laughter, Animal House helped introduce a genre that would sicken overprotective parents for decades to come. After enjoying the excessive nudity, cursing, prankster behavior, and all out college party atmosphere that the 1978 trendsetter created, it really was a shame that the 80's failed to aid in continuing this dumb-fun style of filmmaking, just one bomb after another. However, in the last three years with the addition of Road Trip, the lewd comedy era seems to be relishing a strong rebirth.  In 1999, the Weitz Brothers' American Pie told the story of a pre-college group and there experiments in the field of sexual intercourse. Once again, the offensively funny, crude style seemed heavily borrowed from Animal House. Finally with Road Trip in 2000, we get a movie much closer in both plot and obscenity to my favorite comedy of the 20th century.
Road Trip seems like more of an homage than a rip off of Animal House. Twenty years ago, it was very difficult to get away with the smallest amount of lasciviousness. I like to think of Road Trip as an updated version of Animal House - this time with the possibilities explored and utilized to their fullest potential. At times, Road Trip does exactly what you think it won't do; something so outrageous and unexpected that it becomes shockingly hilarious. To show how Road Trip goes step further than Animal House: remember when Otter and the gang decades ago, with all eyes watching them, uncomfortably sat in a bar knowing they were the only white people in the room? Well in Road Trip, the four main characters are the only white guys in a fraternity house that they crash at, but the scene doesn't end there - the frat plays a prank on one of the boys by claiming they found a Klan Mask in his duffel bag…uh oh. Would this have happened in a movie twenty years ago? Probably not.
The story of Road Trip has little significance. It merely serves as an excuse for pointless but humorous jokes, one after the other. All you really need to know to understand this movie is that a college student accidentally sends a tape to his longtime girlfriend that shows him having sex with another girl. To prevent a disaster, the boy and three of his friends must travel by car from their college in Ithaca, New York to the University of Austin in three days. A hilarious supplement to the film is a character named Barry played by the insane Tom Green. Much like the John Belushi character of Animal House (except instead of crushing beer cans on his forehead, puts live mice in his mouth), Barry has no real point in the movie but to make you laugh at his unique qualities. Doing gags very similar to the ones on his self titled television show, fans should get a kick out of him, while others may be a little confused at his odd approach towards comedy. Unfortunately, at times, he interferes with the central characters and slows the film down a bit, but mostly he is a positive contributor.
Other members of the cast are excellent as lively caricatures of your stereotypical college student (loves to smoke weed, party, and have sex, hates to study). Seann William Scott is great as one of the travelers.  It's hard not to watch him steal a bus from a blind lady and wonder what kind of childhood he must have had. DJ Qualls is also great as another one of the travelers. He's puny, gets pushed around by everyone, and is only on this trip because the others need his car.
Unfortunately, the ending of Road Trip is very disappointing. A weak, empty finish climaxes all of the crazy adventures that lead up to it. Predictable and boring, it certainly can not stand up against the parade ending in Animal House.
Otherwise, you'll have a fun time viewing Road Trip. Let your brain take a time out for once, you won't need it to understand what is going on during the movie and you won't need it to think about the movie's message afterwards. This is the kind of movie, where you don't know what will happen, you laugh really hard with everyone else in the theater, and then you talk about it with your friends the next day. That's it. Enjoy it - then move on with your life until the next one comes out in 2001.

Visualizing time series
AAPL returns compared to SP500 returns : Diff module Both AAPL returns SP500 returns over last 10 years: Series Lite module An optimized version with the support for annotation: Long series module You can even annotate this plot using data from another table! What are the most traded stocks in each month in 2012 : Field Series Module You can also play with different visualizations such as, plotting area, plotting area as stream or percentage, smoothing the interpolated curve, plotting only the sample points, etcField series visualization gets crowded easily. In order to get a high-level picture among a larger set of plots, we use field mashed series, e.g., to visualize all stocks by year.

Example binary classification task on Wisconsin breast cancer dataset (easy task): ML_SVM module Example binary classification task on Stock returns dataset (difficult task): ML_SVM module Example regression task on Wisconsin breast cancer dataset: ML_RIDGE_LINEAR module Example clustering task on Wisconsin breast cancer dataset: ML_K-Means moduleCase study: Big Data Challenge by MIT Big Data Initiative at CSAIL
Let's start by exploring the dataset. Explore_Raw We see that there are 5 fields: trip_id, time, address, longitude, and latitude.
Next, we will use Explore_Calendar module to see the distribution of the data over the time span Explore_Calendar We can see that the data spans from May 1, 2012 to November 30, 2012, and that the data is missing for about two weeks during the latter part of August.
We will use Explore_Diff module to compare the ridership in location to overall ridership across Boston. Explore_Diff We see that ratio fluctuates hugely, and use Explore_Series to get a more detailed view. Explore_Series It is as easy as changing the module option in the query box. There we have many types of visualizations at our disposal.
Explore_series and Explore_longseries modules support annotations. Can we use this feature to see the correlation between events and ridership? Explore_Series
We will use Explore_Word module to see the popular words in the addresses. It shows the words sized according to the number of occurrences. Explore_Word Of course, top word Boston is uninteresting given that this dataset is from Boston. Therefore, let's skip the first entry by starting at record 2, and we can see several zip codes popping up. Explore_Word
We will use Explore_Multi-Field to understand which latitude, longitude, and specific address with high ridership. Explore_Multi-field Here, we truncated the coordinates to the second decimal point using SQL itself. We can see latitude: 42.34 has the highest with 34\% of the ridership, out of which longitude -71.08 takes the highest ridership at 14\%. Within this combination, ``unnamed road Boston'' (which is part of Boston Logan international airport) takes the highest fraction. Altogether, it takes 3\% of the total taxi ridership.
However, making sense of the latitudes and longitudes is easier when they are plotted on a map. We will use Explore_Gmap to view them in Google maps. Explore_Gmap We can also visualize the changes in the ridership against time by making use of xField option. Explore_Gmap GNoT follows the SQL syntax, and offloads data filtering and formatting tasks to the RDBMS. Viewing changes by hour instead of by day is as easy as changing the xField from date(time) to to_char(time, 'YYYYMMDDHH24').
In order to gain a deeper insight into the ridership based on hour of the day, month of the year, and day of the week, we use Explore_Gmap_Crossfilter. Explore_Gmap Crossfilter Using the brushing feature, we can learn that between 10 PM and 12 AM taxi rides peak around Boston University, Boylston Street / Prudential Tower, and Terminal E at Boston Logan international airport.
While we can make such observations based on time and location, can we generate a hypothesis? We turn to a statistical method - k-means - to perform unsupervised clustering of the coordinates. Let's start by clustering the coordinates into 5 clusters. Explore_K-means What if we add the day of the week as the third dimension? Since, the range of the day of the week is not similar to the range of latitude and longitude (i.e., they have different units), and we apply Z-score normalization before applying K-means. It is as simple as picking Z-score from pre_process option in GNoT. Here, we see a totally different pattern emerging. Explore_K-means2
Finally, let's look at the challenge problem itself: predicting the number of rides within 250 meters of a location (e.g., (-71.057114, 42.343365)) within a given time window. Before building a complex model, we can use GNoT to visually explore the data in order to test the viability of the task and identify useful feature combination. For instance, we will use ML_Ridge_Linear module to explore the accuracy achievable in predicting the ridership in an hour with only three features: day of the week, hour of the day, and month. Explore_Ridge_Linear2 Even with this basic model, we achieve a coefficient of determination (R2 = 0.2224) when predicting 10% of the time windows by learning the model on the rest. Using GNoT, we can also try different feature combinations, feature transformations such as applying interactions and quadratic transformations on the features, and pre-processing such as applying Z-score or PCA transformation. Using provenance, we can see the contributing factors for large squared errors (filter by squared errors): unsurprisingly month 8 stands out as data is corrupted in that month. Further, compared to the rest, peak hours and weekends stand out. This indicates the problem of capturing the tails of the distribution (filter by squared errors and ridership), i.e., not adequately modeling riderships with high amounts that fall at the tail of the distribution.

At first I didn't have the intention on writing this chapter, and
I still think, that there's no need to write it. This part is surprisingly
well document in Maya's help and on the Net. I'm therefore rather summarizing
the techniques, than explaining every detail. Feel free to look for more
information on the web, or even to complement this chapter (it's open-doc,
isn't it;).
In order to write an exporter one needs to interface in some way with
Maya. The more obvious one is of course by writing a plugin, and
implementing Maya's "interfaces". Another interesting approach consists in
writing a stand-alone application, that just uses Maya's libraries. I
recommend keeping the exporter general enough, so it can be used as both.
If the exporter should be accessible from within Maya, the exporter needs
to derive from
MPxFileTranslator
. Furthermore some methods must be
implemented:
haveReadMethod
: most of the time returns
false
.
haveWriteMethod
: most of the time returns
true
.
reader
: most of the time returns an error.
writer
: exports the scene. The method, that
does all the work.
identifyFile
: recognizes the plugin's files
(or not;).
defaultExtension
: obvious.
Note however, that
gpExport
already does all this work for
you. By reusing the framework only two methods need to be implemented:
Export
: more or less equivalent to writer
getExtension
: more or less equivalent to
defaultExtension
Writing an executable is even easier (as long as one knows what libraries
are needed, and how to link them to your executable). One just needs to
initialize the MLibrary
, which can be conveniently done using
gpExport
's MayaLibrary
-class. In the latter case one just needs
instantiate this class, as shown in executable.cpp
:
54: MayaLibrary library((char*)exporterName.c_str());
55:
56: loadScene(inFile);
57:
58: MFileObject outMFile;
59: outMFile.setFullName(outFile.c_str());
60: ExporterConfig config(outMFile, "", false);
61:
62: exporter.Export(config);
|
I might say: this file is an excellent example of a
Maya-executable;). Compiling the cpp-file is then easy. What's way more
difficult is the linking. I heavily advise to reuse gpExport
's
Makefile. It could save you a lot of time...

Gathering of great whites
by The Canadian PressIt’s not officially Shark Week, but for trackers along the East Coast, several great white sharks are putting on a show.
The Charlotte Observer reports nine sharks tagged by the ocean data-gathering organization OCEARCH have appeared near the coast in a five-day span, including two that are about 12 feet long.
Tracking shows two sharks near Charleston, South Carolina. Five more are near the Outer Banks.
It’s unclear why so many sharks are swimming near shore in the same region, but OCEARCH’s Chris Fischer told The Outer Banks Voice that the area is a key spot in the shark’s migration.

## Properties vs Attributes Based on [CustomElements-v1](http://www.w3.org/TR/custom-elements/), **Pacem JS** identifies the observable attributes of its components via `@Watch` decorators (**ES2017** feature) on the corresponding properties, we'll return on that in a near future. Observable attributes are *evaluated* the **MVVM** way in the declarative markup either as a static or dynamic outcome (**binding**). Bindings have their own peculiar syntax. The syntax provided for bindings will likely change, but the current state of the art is the following: - Only `Watched` properties are subject to binding; - `Watched` properties are evaluated against their attribute counterpart (properties are the **camelCased** version of the **kebab-cased** attributes, and viceversa); - Bindings are explicited with double handlebars `{{...}}` syntax; - Bindings can be two-way directional, in that case they have the following form: `{{ ..., **twoway**}}`; - Available _Scope_ is the whole DOM. Element references are resolved via `id` attributes, prepending a `#` (like in css selectors). Example:
type here:
keyboardsee result here:
compare_arrows
## Other Bindings Bindings might also want to refer to: - The element itself, then use `{{ this.property }}`; - A dynamic `RepeaterItem` inside a `<pacem-repeater>`, then use `{{ ^item.property }}` to access the current item properties, or `{{ ^index }}` for the current item index; - **Nested** repeaters: to access upper level dynamic items just prepend more `^`! Example:

QML Dynamic View Ordering Tutorial 4 - Sorting Items
Drag and drop isn't the only way items in a view can be re-ordered, using a DelegateModel it is also possible to sort items based on model data. To do that we extend our DelegateModel instance like this:
DelegateModel { id: visualModel property var lessThan: [ function(left, right) { return left.name < right.name }, function(left, right) { return left.type < right.type }, function(left, right) { return left.age < right.age }, function(left, right) { if (left.size == "Small") return true else if (right.size == "Small") return false else if (left.size == "Medium") return true else return false } ] property int sortOrder: orderSelector.selectedIndex onSortOrderChanged: items.setGroups(0, items.count, "unsorted") function insertPosition(lessThan, item) { var lower = 0 var upper = items.count while (lower < upper) { var middle = Math.floor(lower + (upper - lower) / 2) var result = lessThan(item.model, items.get(middle).model); if (result) { upper = middle } else { lower = middle + 1 } } return lower } function sort(lessThan) { while (unsortedItems.count > 0) { var item = unsortedItems.get(0) var index = insertPosition(lessThan, item) item.groups = "items" items.move(item.itemsIndex, index) } } items.includeByDefault: false groups: VisualDataGroup { id: unsortedItems name: "unsorted" includeByDefault: true onChanged: { if (visualModel.sortOrder == visualModel.lessThan.length) setGroups(0, count, "items") else visualModel.sort(visualModel.lessThan[visualModel.sortOrder]) } } model: PetsModel {} delegate: dragDelegate }
Walkthrough
Items in a DelegateModel are filtered into groups represented by the DelegateModelGroup type, normally all items in the model belong to a default items group but this default can be changed with the includeByDefault property. To implement our sorting we want items to first be added to an unsorted group from where we can transfer them to a sorted position in the items group. To do that we clear includeByDefault on the items group and set it on a new group name 'unsorted'.
items.includeByDefault: false groups: VisualDataGroup { id: unsortedItems name: "unsorted" includeByDefault: true }
We sort the items by first finding the position in the items group to insert the first unsorted item and then transfer the item to the items group before moving it to the pre-determined index and repeat until the unsorted group is empty.
To find the insert position for an item we request a handle for the item from the unsorted group with the get() function. Through the model property on this handle we can access the same model data that is available in a delegate instance of that item and compare against other items to determine relative position.
function insertPosition(lessThan, item) { var lower = 0 var upper = items.count while (lower < upper) { var middle = Math.floor(lower + (upper - lower) / 2) var result = lessThan(item.model, items.get(middle).model); if (result) { upper = middle } else { lower = middle + 1 } } return lower } function sort(lessThan) { while (unsortedItems.count > 0) { var item = unsortedItems.get(0) var index = insertPosition(lessThan, item) item.groups = "items" items.move(item.itemsIndex, index) } }
The lessThan argument to the sort function is a comparsion function which will determine the order of the list. In this example it can be one of the following:
property var lessThan: [ function(left, right) { return left.name < right.name }, function(left, right) { return left.type < right.type }, function(left, right) { return left.age < right.age }, function(left, right) { if (left.size == "Small") return true else if (right.size == "Small") return false else if (left.size == "Medium") return true else return false } ]
A sort is triggered whenever new items are added to the unsorted DelegateModel which we are notified of by the DelegateModelGroup onChanged
handler. If no sort function is currently selected we simply transfer all items from the unsorted group to the items group, otherwise we call sort with the selected sort function.
groups: VisualDataGroup { id: unsortedItems name: "unsorted" includeByDefault: true onChanged: { if (visualModel.sortOrder == visualModel.lessThan.length) setGroups(0, count, "items") else visualModel.sort(visualModel.lessThan[visualModel.sortOrder]) } }
Finally when the selected sort order changes we can trigger a full re-sort of the list by moving all items from the items group to the unsorted group, which will trigger the DelegateModelGroup onChanged
handler and transfer the items back to the items group in correct order. Note that the DelegateModelGroup onChanged
handler will not be invoked recursively so there's no issue with it being invoked during a sort.
property int sortOrder: orderSelector.selectedIndex onSortOrderChanged: items.setGroups(0, items.count, "unsorted")

Name Model¶
The final page of the CCA model creation wizard, shown in Figure 22, provides editable fields to enter a Name and an optional Description for the model. A default name of New CCA Model is provided, but the model list on the project page will become uninterpretable if you use this for all your models. Additionally, you should select a Marking from the dropdown list of choices. These markings are specific to your institution and the Slycat™ server you are using. The selected marking identifies the sensitivity of the data that is being analyzed, both for your own benefit and for other team members. This marking is used to label the model, both on the project page and within banners at the top and bottom of the model visualization. Once this information has been entered, click the Finish & Go To Model button in the lower right. Slycat™ will then transfer you to the model visualization page. When the analysis has completed, the CCA model will be displayed. If processing is still ongoing, the message “The model is being computed. Patience!” will be shown.

PORTFOLIO
Below you can see some projects I've been working on lately.I divide each project into four follow-up areas: comprehensive research, wireframing, design & development. This process allows me to create great product with client goals in mind.


Get spiritual. A study conducted by the formidably sober and scientific Harvard University found that patients who were prayed for recovered quicker than those who weren’t, even if they weren’t aware of the prayer.
Copy your kitty: Learn to do stretching exercises when you wake up. It boosts circulation and digestion, and eases back pain.
Don’t skip breakfast. Studies show that eating a proper breakfast is one of the most positive things you can do if you are trying to lose weight. Breakfast skippers tend to gain weight. A balanced breakfast includes fresh fruit or fruit juice, a high-fibre breakfast cereal, low-fat milk or yoghurt, wholewheat toast, and a boiled egg.
Neurobics for your mind.  American researchers coined the term ‘neurobics’ for tasks which activate the brain's own biochemical pathways and to bring new pathways online that can help to strengthen or preserve brain circuits.
Bone up daily. Get your daily calcium by popping a tab, chugging milk or eating yoghurt. It’ll keep your bones strong. Remember that your bone density declines after the age of 30. You need at least 200 milligrams daily, which you should combine with magnesium, or it simply won’t be absorbed.
Load up on vitamin C.We need at least 90 mg of vitamin C per day and the best way to get this is by eating at least five servings of fresh fruit and vegetables every day. So hit the oranges and guavas!
Pure water. Don’t have soft drinks or energy drinks while you're exercising. Stay properly hydrated by drinking enough water during your workout (just don't overdo things, as drinking too much water can also be dangerous). While you might need energy drinks for long-distance running, in shorter exercise sessions in the gym, your body will burn the glucose from the soft drink first, before starting to burn body fat. Same goes for eating sweets.
 To improve your fitness quickly and lose weight, harness the joys of interval training. Set the treadmill or step machine on the interval programme, where your speed and workload varies from minute to minute. Build up gradually, every minute and return to the starting speed. Repeat this routine. Not only will it be less monotonous, but you can train for a shorter time and achieve greater results.

At the end of the original Fallout, the hero, the Vault Dweller, was exiled by the vault overseer for prolonged exposure to the outside world. Unable to return home, the Vault Dweller, with a group of willing companions, traveled far north. Eventually, they started their own tribal village called Arroyo in what we know as Oregon. Decades have passed since the original Fallout, and the Vault Dweller disappeared from Arroyo after writing their memoirs.
In the time since the Vault Dweller's exile, a new government known as the New California Republic (abbreviated as NCR) has begun to unify the southern towns and is spreading to the north. A mysterious new organization known as the Enclave has emerged with the most sophisticated technology in the wastes, even surpassing the Brotherhood of Steel. A new drug, Jet, has become a burden on many towns, its addictive properties forcing many to rely on the town of New Reno to keep them supplied.
During 2241, the humble village of Arroyo suffered the worst drought on record. Faced with this hardship, the village elder asked the direct descendant of the Vault Dweller, referred to as the Chosen One, to perform the quest of retrieving a Garden of Eden Creation Kit (G.E.C.K) for Arroyo. The GECK is a device that can create thriving communities out of the post-apocalyptic wasteland.
The player, assuming the role of the Chosen One, is given nothing more than the Vault Dweller's jumpsuit, a RobCo Pip-Boy 2000 handheld device, a Vault 13 water flask, and some cash to start this quest.
A decendent of the vault dweller, selected by the elder of Arroyo to go on a quest to the outside world of their tribe in order to find the precious G.E.C.K.
The daughter of aradesh, one a naive and intrepid child, now an mature and wise old woman, serving as the president of the New California Republic in Shady Sands, the capital of the republic
the habitants of what remains of San Francisco, decendents of chinese soldiers and sailors whose nuclear submarine got stranded in the San Francisco Bay.
the leader of a group known as The Enclave, the remains of the old U.S. government who claim the wasteland as their territory, and plan on launching a clensing of the nation, by basically killing every person they deem a "mutant", wich by their eyes is everyone except themselves.
the best soulder the Enclave has, powerful, intimidating and merciless, rose throught the ranks of the Enclave and became the subject of phisycal augmentations, beeing sealed in his personalized massive Power Armor, leads the forces on the wasteland since he is considered to mentally unstable and dangerous to have him anywhere else.

title=A New Post on Artima.com Called 'SOA, 5 Years In' date=2010-04-26 type=post tags=blog status=published ~~~~~~
I've just posted a blog on Artima.com called SOA, 5 Years In. In it, I talk about some of the core value principals behind Thomas Erl's excellent Service Oriented Architecture: Concepts, Technology, and Design. Check it out!


This is a complete draft, but it still has lots of minor errors, and possibly some major ones. There are a number of small details missing from the specification, mostly concerning error conditions. Those details are apparently known only within Microsoft. I hope to talk to engineers there to learn these details and correct any inaccuracies in the specification.
The current specification provides a fairly simple model of the API, in which kernel calls and returns are atomic actions. The specification thus does not describe the details of how kernel calls are made. This seems to me to be the appropriate interface for application programmers (and for the implementers), who already understand how procedure calls are coded. I intend eventually to provide a lower-level specification that does model some of the details of kernel calls. I will do this by using an interface refinement that relates the higher-level and lower-level models of procedure calls, and is independent of the particular kernel calls being specified.
The specification is written in an "object oriented" style, which is discussed in the introduction.
The specification is:

Match Play. Red trails 0-2 to 7. How should Red play 21?
pips Red=117 White=131
(CorrectAnswer= 0/0, ErrorScore= 0)
6/3* with only one direct cover number is too bold. This is a choice between 8/5 and 12/9*.
The latter gives White the chance of making Red’s 3-pt for a 3-4 back game. 12/9* gains good ground in the race and duplicates White’s fives.
8/5 wins more gammons but 12/9* wins more games. At the end of the day there is only 0.013 between the two moves so either is OK but technically 12/9* is marginally best.
The latter gives White the chance of making Red’s 3-pt for a 3-4 back game. 12/9* gains good ground in the race and duplicates White’s fives.

DB2 UDB V8.1.4 implements a new table design called range-clustered tables.
A range-clustered table (RCT) is a table layout scheme where each record in the table has a predetermined offset from the logical start of the table.
For each table that holds your data, consider which of the possible table types would best suit your needs. For example, if you have data records that will be loosely clustered (not monotonically increasing), consider using a regular table and indexes. If you have data records that will have duplicate (not unique) values in the key, you should not use a range-clustered table. If you cannot afford to preallocate a fixed amount of storage on disk for the range-clustered tables you might want, you should not use this type of table. These factors will help you to determine whether you have data that can be used as a range-clustered table.
An algorithm is used to equate the value of the key for the record with the location of a specific row within a table. The basic algorithm is fairly simple. In its most basic form (using a single column instead of two or more columns to make up the key), the algorithm maps a sequence number to a logical row number. The algorithm also uses the record's key to determine the logical page number and slot number. This process provides exceptionally fast access to records; that is, to specific rows in the table. Using the key, the exact logical location of the record on disk can be found using linear interpolation. The algorithm is more complex when multiple columns are used to create the key.
The algorithm does not involve hashing because hashing does not preserve key-value ordering. Preserving key-value ordering is essential because it eliminates the need to reorganize the table data over time.
Each record key in the table should have the following characteristics:
The ALLOW OVERFLOW option is used when creating the table to allow key values to exceed the defined range. The DISALLOW OVERFLOW option is used when creating the table where key values will not exceed the defined range. In this case, if a record is inserted out of the boundary indicated by the range, an SQL error message is returned.
Applications where tightly clustered (dense) sequence key ranges are likely are excellent candidates for range-clustered tables. When using this type of key to create a range-clustered table, the key is used to generate the logical location of a row in a table. This process avoids the need for a separate index.


We love food and friends and therefore we need to create the ultimate tool to combine the best of both worlds. dumpster chef is an adventurous journey and your chance to make new friends and the world a better place by opposing the throw-away society.
Find Out Moredumpster chef is a smart tool for helping you to find a dumpster dive place close to your location and needs. Just ask for Spaghetti and the dumpster bot will answer. Always available, as a smartphone app, you are only one click away from nice food and great people.
Furthermore dumpster chef matches you with people that have similar interests and dinner style (the dumpster recommender). After diving together, you can use recipes and preparation tips for the perfect dinner with your new friends.
The service will also notify you if a window for diving opens close to your current location. The service also includes a new match making concept. You only deserve the best.
Share your happiness!
We only have one world. If we continue living that way we will need three worlds.
If we have the possibility to improve people's life, then we should do it without thinking too much about it.
Dumpster diving and cooking is a good way to unite people!
It is nice to know someone with whom you can forget the seriousness of life with a lot of fun.
The Food and Agriculture Organization of the United Nations (FAO) reports on approximately 1.3 billion tonnes of food, which gets dumped worldwide every year. A big part of this amount (about 157,000 tonnes) gets contributed by Austria. This means that every third edible food gets threw away. Vienna throws away an amount of bread which could Graz use for supply all inhabitants.
An exceeded expiration date does not mean automatically, that the product is inedible. Also the quality is not affected, even though fruits and vegetables are bruised.
In the USA dumpster diving was invented in 1990. In metropolises like New York the communities are expanding continuously by guiding a “container tour” to introduce newbies to the concept of dumpster diving.
According to the legal situation in Austria (and in many other countries) dumpster diving is still a grey area. Garbage in a container does not belong to anyone. If the private estate or the container is locked, then you commit trespassing, which is a criminal act. It is essential to understand the legal situation in the current country.
The number of supermarkets which tolerate dumpster diving are getting bigger and bigger and therefore set an example.
There already exist initiatives which pay attention to utilization of food out of the garbage bin, for example wastecooking from the film-maker and activist David Groß (www.wastecooking.com).

TAPAS (Testing Aligner Performance for Ancient Samples) is a software package written in Python and R which enables you to test how well parameters of NGS short read mappers perform when mapping reads to a reference. The reads can be subjected to artificial damage to simulate evolutionary distance and chemical alteration of ancient DNA samples.
Installation
Download the package from the project's GitHub page
See the section Dependencies of the scripts to learn about the installation process of TAPAS
Workflow
TAPAS can be used to generate artificial NGS reads from a given reference genome, introduce mutations into them which follow a user-defined pattern and evaluate the mapping success of the reads with a user-supplied short read mapper.
See the section about Input files to see which files must be supplied prior to the analysis.
In the following, the workflow is outlined, where links are provided to manual chapters which give more detail on each step.
- Prepare the reference genome. See section Genome Preparation
- Generate artificial reads from a sample genome. See Read generation
- Mutations must be introduced into the reads to mimic chemical damage of ancient DNA and evolutionary distance of the reads to the reference. Read the section about Read mutation for more information
- The mutated artificial reads are mapped back to the reference from which they originated. This simulates the process of mapping ancient DNA reads to a recent reference genome. TAPAS allows for comparison of different mapping parameters in terms of mapping success. Section Mapping and How to write a mapping script provide details on how the mapping commands and parameters are provided to TAPAS.
- The read mapping yields one SAM file for every mapping parameter set tested. The section SAM parsing provides information on how the mapping positions of the artificial reads can be compared to their known, true, positions in the reference to determine measures of mapping accuracy like sensitivity and specificity.
- Finally, the obtained accuracy values can be analysed to determine the importance of a certain mapping parameter choice for the mapping success. The section Parameter influence provides details.
Apart from that, the Appendix lists additional information:
- All commands from the tutorial, collated into one script for overview: Appendix A1
- An overview of all scripts provided by TAPAS: Appendix A2
- How to put together artificial FASTQ files from their parts (1) nucleotide strings, (2) quality strings and (3) read names to allow for more fine-grained read generation and incorporation of external tools: Appendix A3: Advanced Read generation
- Appendix B: Glossary

Data is mostly returned as JSON documents. Your application must tolerate the order of document members changing over time, and expect to receive members it hasn't seen before.
The API can only be accessed over TLS 1.2.
It is important to keep your API keys secure, to prevent them being discovered, your account being compromised and your rate-limit quota being exceeded. There are a few best practices that can help with this:
Storing keys in your application code increases the risk that they will be discovered, particularly if any of your source code is made public, or can be viewed by people who should not have access to the key. Instead, you should consider storing them inside environment variables or configuration.
If you store API keys in files, perhaps inside a configuration or environment file, these should not be stored inside the application source tree, just in case part or all of the source is made public or can be viewed by people who should not have access to the key.

Spiceworld (1998) 1 star out of 4. Starring the Spice Girls.
Spice World tries very hard to be A Hard Day's Night. Unfortunately, it turns out to be "Blandworld," a movie aimed at the female pre-pubescent fans of the Spice Girls, a British girls group whose members offer more attitude than talent.
Luckily, it is their attitude that salvages this movie. While the Spice Girls are by no means actresses, their lack of self-consciousness before the camera gives the film a naturalistic vibrancy.
As performers the Spice Girls are merely adequate. They strut and pose rather than dance, and they at least sing on key. Their songs are unremarkable, and after a while, they all begin to sound alike.
Despite cameos from Elton John and Elvis Costello, among others, most of the regular performances are embarassingly hammy.
It's a shame to see a wonderful actor such as Richard E. Grant, as the girls' manager, mug his way through the proceedings. Roger Moore, as the behind-the-scenes Mr. Big, is a travesty.
More than anything else, Spice World needs a harder edge. The girls try too hard to please and to be liked and accepted, unlike the Beatles who, in A Hard Day's Night, enjoyed thumbing their noses at the establishment.
A little more seasoning added to the Spice World recipe, could have made for a tasty treat instead of a safe, unoriginal extended music video.
