Versions
The Power Tour plugin come's in three versions, full, lite and tiny. As every tour is build differently the needed options will vary, therefor we made three versions of the plugin, from full with all options to tiny with almost no options. Click on the 'overview' tab for a list of each version and the available options.
Prevent errors
Only use 1 version, do NOT use different version on the same page.
// only use 1 version per page! // full version  // lite version  // tiny version
//plugin call(namespace is the same for all versions) $.powerTour({ //options });
All plugin helpers (see: misc -> plugin helpers -> class name) and API methods work in all of the 3 versions.

Setup plugin
The Power Tour plugin alows you to setup multiple tours with multiple steps on the same page. You even can continue on the next page with the tour if needed.
As of version 2.x.x allmost all steps options can be replaced by the 'stepDefaults' options, this way you don't have to repeat your code. See more about this in the 'setup plugin' section.
As of version 2.2.0 you dont have to use the initial plugin selector anymore.
Prevent errors
Initializing the tour setup more than once on a page will result in an error.
Plugin namespace
All three versions of the plugin use the same namespace $.powerTour
.

Tour triggers
The plugin provides 3 ways to start a tour:
- using the trigger option(button)
- using the public method called 'run'
- using the url parameter
All of these 3 ways allow a 'startwith' option which you allow to choose a step to start with. If this option is not used it will use het 'startWith' option or if this option is not used the first step.
 Start tour 1(step 1)  Start tour 1(step 4)
$(document).ready(function($){ // build tour $.powerTour({ tours:[ { trigger: '', startWith: 1, // all other options } ] }); // run the first tour(more info the the 'API methods' section. $.powerTour('run',1); //or $.powerTour('run',[1, 4]);// first tour, fourth step(overiding the startWith option) });
 http://www.yoururl.com?powertour=1&startwith=4
Building the steps
You can use any kind of content inside the steps, this can be a simple form, some text or an carousel. You can even use AJAX to load any kind content into a step once it's shown for the first time, this can be handy with big tours or steps.
More about using AJAX can be found on the extend page.
Hidden and dynamic content
Using hidden or dynamic content inside the step may require the use of the 'update' method to re-position the step.
Unique id's
All steps need to have an unique id, this id is used to place the content in the right wrapper(step). You can not use the same step serveral times in the tour, as this will show an empty wrapper(step).

Positions
Every step has it's own position option. The position can be divided into 2 types, 1. a hook related position, 2. a screen related position (these are fixed positions). Both types can be adjusted with a negative/positive 'offsetX' and 'offsetY' value.
steps : [ { position : 'br', //position : false, // use this if you dont want to set any position offsetX : -50, offsetX : 44 }, { // next step } ], stepDefaults : [ { position : 'tr', //position : false, // use this if you dont want to set any position offsetX : 20, offsetX : -40 } ]

Callback functions
The Power Tour plugin provides several callback function which are fired at certain points in the tour. These functions can contain your own custom code to extend the power of this plugin even more.
Valid code
You must use valid code inside the callback functions, if not the tour will stop working.
steps : [ { onShowStep : function(ui){ // example: add/remove a custom class ui.previousStep.removeClass('custom-current-step-class'); ui.currentStep.addClass('custom-current-step-class'); } }, { // next step } ], stepDefaults : [ { onShowStep : function(ui){ // example: add/remove a custom class ui.previousStep.removeClass('custom-current-step-class'); ui.currentStep.addClass('custom-current-step-class'); } } ]

Highlight elements
All steps and hooks can be highlighted towards the whole tour. The main options 'highlightStartSpeed' will control the starting speed (fadein) and 'highlightEndSpeed' will control the ending speed (fadeout) of the overlay background. The options 'highlight' will control the highlighting (true/false) and 'keepHighlighted' will control the visibility of the overlay between the steps if both steps have the 'highlight' option set to true.
When needed you can use the class 'powertour-highlight' (see plugin misc -> helpers) to highlight other elements during the tour.
$.powerTour({ tours : [ { highlightStartSpeed : 200, highlightEndSpeed : 200, steps : [ { highlight : false, keepHighlighted : false } ], stepDefaults : [ { highlight : true, keepHighlighted : false } ] } ] });
Animations
You can choose from more than 60 available CSS3 animations to spice up the tour. Every single step can have there own kind of in and out animation.
All animations are provided through a third-party css file called 'animate.css', more about the this file can be found on the animate.css page.
Tiny version
Custom CSS3 animations provide by the animate.css file do not work in the tiny version of the plugin.
CSS3 support
If the browser does not support CSS3 animations a simple show/hide is used instead.
steps : [ { fxIn : 'fadeIn', fxOut : 'bounceOutLeft' }, { // next step } ], stepDefaults : [ { fxIn : 'fadeIn', fxOut : 'bounceOutLeft' } ]
The tiny version of the plugin does not support the use of the animate.css animations as the 'fxIn' & 'fxOut' options are not avialable in this version but it has 2 extra custom classes which you can use to add you own custom CSS animations if needed.
These classes can befound at the bottom of the powertour.x.x.x.css
file and are only available in the tiny version.
/* NEW 3.0.0 Used FX IN/OUT classes for tiny version, you can modify these 2 classes. */ .powertour-fxin{ opacity : 1; -moz-transition : 0.4s; -webkit-transition : 0.4s; transition : 0.4s; } .powertour-fxout{ opacity : 0; -moz-transition : 0.4s; -webkit-transition : 0.4s; transition : 0.4s; }

Misc
Sometimes it will happen that you have done something wrong, have forgotten something therfore in the next tab a list with most common issues.
Most common issue
Most common issue are almost always CSS related (see first issue in table).
Always double check
Before contacting us and saying the plugin doesn't work please check and recheck your code.
| Problem | Cause | Solution |
|---|---|---|
| Step are not displayed correctly. | Overriding css rules. | As the steps are child element of the hookto elments it can happen that the step will inherited the hookto element css rules. The issue scan be fixed by managing the hookto css rules. Most issues are z-index or position related. |
| The tour wont start, or doesn't run as it should. | Typo(one or more) or using multiple instances of the plugin. | Check the code that you have added/changed. |
| The position of the step isn't right when i try to hook it to an table cell. | Table cells can't have an absolute position. | Wrap the cells inner with an element(div, span). |
| The hook isn't highlighted. | The parent(s) element have an position absolute. | Change the parent(s) position to relative, or disable the highlight option. |
| The steps FX are not working. | Browser does not support CSS3. | Use a modern browser. |
| The step is empty. | Using multiple tours on the same page. | The 'content' id can only be used once, therefor use a different id(step). |
| The wrong step/tour is selected. | Using the wrong step/tour number. | All options/settings except the url parameters and the 'goto' navigation are zero based numbers. |
| Some options are not working. | Unquoted vs quoted values. | Some values(boolean and integers) need to be quoted and some dont. |
| Uncaught TypeError: Cannot read property 'top' of undefined | Cant find the 'hookTo' element. | Use an existing element. |
| Problem | Cause | Solution |
The plugin offers a couple of helper classes/datasets which you can use to extend the Power Tour plugin even more. Most of these helpers are not mentioned in the documentations or extend pages.
| Class name | Description | Since |
|---|---|---|
| powertour-disable-cancel | If you use the 'easyCancel' option only the hook, step and navigation are excluded, everything else will trigger the ending of the tour. This class can be used to excluded extra elements from this event. | 2.0.0 |
| powertour-disable-action | This class when used on an element with the 'data-powertour-action' attribute will disable this button, this can be usefull if you are adding some kind of validation inside a step. | 2.0.0 |
| powertour-highlight | This class is used by the plugin it self to highlight the hooks, but you can use this class your self if you need to highlight other elements during the tour. | 2.0.0 |
| powertour-activehook | This class will be added to the 'hookTo' elmenent once the step is active(visible), this class can be used to give the 'hookTo' element different CSS rules once it's active. | 2.7.0 |
| powertour-activestep | This class will be added to the step elmenent once the step is active(visible), this class can be used to give the step element different CSS rules once it's active. | 2.8.0 |
| Class name | Description | Since |
| Dataset | Value | Description | Since |
|---|---|---|---|
| data-powertour-placeholder | timer | This placeholder is used to display the remaining time left untile the next step. This is used with the 'timer' option. | 2.0.0 |
| Dataset | Value | Description | Since |

Edmund gives Great Britain winning start in Davis Cup quarter-final with Germany
Edmund defeated Kohlschreiber 6-3 7-5 to put Britain one rubber away from the semi-finals.
Kyle Edmund gave Great Britain’s Davis Cup team a winning start for the second day in a row with another impressive victory over Germany’s Philipp Kohlschreiber.
Andy Murray was once again left out for the quarter-final at Madrid’s Caja Magica amid doubts about his fitness but he had plenty to cheer from the sidelines as Edmund produced a strong and composed performance to win 6-3 7-5.
The only disappointment was the size of the crowd, which appeared noticeably smaller than for Britain’s two group matches – a concern Murray had raised ahead of the event.
The British fans who had stayed made a good noise, though, and Edmund responded in style.
At 36, Kohlschreiber’s best days may be behind him but he remains a dangerous customer, particularly off his one-handed backhand, and he has been in good form here.
The German was a little wild in the first set and Edmund took advantage, securing the only break of serve in the sixth game.
The second was much tighter. Kohlschreiber became the first player this week to break the Edmund serve for 3-1 but a fine game from the Yorkshireman reduced the arrears straight away.
Edmund is known for his bulldozer forehand but it was his backhand doing a lot of the damage and another break for 6-5 set up a chance to serve for the match, which he took to love.
That set the stage for British number one Dan Evans, who kept his place ahead of Murray despite two defeats to lower-ranked players this week, to take on German number one Jan-Lennard Struff.

Implementations of algorithms for data analysis based on the rough set theory (RST) and the fuzzy rough set theory (FRST). We not only provide implementations for the basic concepts of RST and FRST but also popular algorithms that derive from those theories. The methods included in the package can be divided into several categories based on their functionality: discretization, feature selection, instance selection, rule induction and classification based on nearest neighbors. RST was introduced by Zdzisław Pawlak in 1982 as a sophisticated mathematical tool to model and process imprecise or incomplete information. By using the indiscernibility relation for objects/instances, RST does not require additional parameters to analyze the data. FRST is an extension of RST. The FRST combines concepts of vagueness and indiscernibility that are expressed with fuzzy sets (as proposed by Zadeh, in 1965) and RST.

HTML5 introduced several new tags, including:
- Item 1
- Item 2
Doing layout with HTML and CSS has always been a challenge. First we had tables, then floats. Now, we have more options.
Flexbox is a new layout technique that is very intuitive (sorta) and makes more complicated layouts dead simple.
.container {
display: flex;
justify-content: row-reverse;
align-items: center;
}
.child {
flex: 1 1 250px; /* grow | shrink | basis */
}
.container {
display: flex;
justify-content: row-reverse;
align-items: center;
}

Still an upcoming standard, CSS Grid will replace old HTML table layout design and have incredible flexibility.
Taken from http://gridbyexample.com/examples/example5/
With the introduction of CSS variables, we can lessen the need for CSS pre-processors like LESS or SASS.
:root {
/* Palette generated by Material Palette - materialpalette.com/blue-grey/red */
--primary-color-dark: #455A64
--primary-color: #607D8B
--primary-color-light: #CFD8DC
--primary-color-text: #FFFFFF
--accent-color: #FF5252
--primary-text-color: #212121
--secondary-text-color: #757575
--divider-color: #BDBDBD
}
.container {
background: var(--primary-color-dark);
}
Media queries let CSS react differently to different-sized viewports.
.container {
width: 400px;
margin: 0 auto;
}
@media only screen and (min-width: 670px) {
.container {
width: 600px;
}
}
@media only screen and (min-width: 1080px) {
.container {
width: 900px;
}
}
The Fetch API is a new standard for receiving data from sources, replacing XMLHttpRequest.
var myImage = document.querySelector('img');
fetch('flowers.jpg').then(function(response) {
return response.blob();
}).then(function(myBlob) {
var objectURL = URL.createObjectURL(myBlob);
myImage.src = objectURL;
});
Already introduced with libraries like Polymer, web components are a way (using the shadow DOM) to write custom HTML tags such as <calendar> or <modal>, tags that are specified in your HTML/JS files.
View on webcomponents.org
Frameworks are a way to increase developer speed, with features like web components. They also often have features like linting, packing, and hot reload to make development quicker.
Vue JS is a framework for building web interfaces, focusing primarly on the view layer. It also works well in tandem with other libraries to create single page apps like the other major frameworks.
By using service workers and caching, an offline-first approach is far better for the user, both when fully offline and when in 'lie-fi' mode.
Push notifications are common with native applications, but there is now the ability to do them through the browser using service workers.
Service workers are the replacement for app-cache, and allow developers to do caching and other things with just javascript, not some other format.

reg.waiting.postMessage({action: 'skipWaiting'});
return;
}
The culmination is progressive web apps.

We have two styles of back yard BBQ pits, All American and Old Country. They both produce great tasting barbeque with less effort than ordinary BBQ pits.
Our BBQ pits are designed to reduce hot and cold spots within the cooking chamber, to retain the heat, prevent smoke from leaking, have a long life and, basically, aid you to barbeque.
They have an excellent heat retention capacity. They have a big firebox baffle and the smoke stack is placed in the center of the grill section this helps to reduce the cold and hot spots in the grill section. The fire box has a fire grate designed to promote air flow and sliding cooking grate.

The Flask Debug Server
Table of Contents
Background
This is documented on the Flask site, but I was trying to help someone debug some old server code that I'd written and couldn't remember how to debug it, so I'm documenting it here as I go through remembering it again so I'll have a single reference to use the next time. Some of the settings look different from what I remember using so I think that Flask has changed a little over time, but since I didn't document it the first time I don't have a record to compare against (well, I probably have some notes in a notebook but it's hard to refer to that when sitting at someone else's desk).
Setup
The Flask Quickstart tells you what to do, but for some reason when we googled it, the instructions were different, I think it might have lead us to an older form of the documentation. This is the current version (May 20, 2018.)
The Environment Variables
The Flask App
First you have to tell flask which file contains your flask app by setting the FLASK_APP
environment variable. In my case I'm using connexion, an oddly-named adapter that adds support for swagger/OpenApi to Flask. So the file that has the app has this line in it.
application = connexion.FlaskApp(__name__)
In this case that's a file named api.py
which we'll say is in the server
folder (it isn't, but that's okay) so we need to set our environment accordingly. I use the fish shell so the syntax is slightly different from the Quick Start example. Also - and this caused me a lot of trouble - when I didn't pass in the name of my FlaskApp
instance I got this error:
Error: Failed to find application in module "server.api". Are you sure it contains a Flask application? Maybe you wrapped it in a WSGI middleware or you are using a factory function.
So I had to specifically tell flask the name of my app by appending it to the end of the setting (perhaps it is looking for app
specifically, but I called mine application
).
set -x FLASK_APP server.api:application
Development Mode
If you want the server to automatically reload when it detects changes then you should to set the FLASK_ENV
environment variable to development
. This is similar to using FLASK_DEBUG
but I think it adds the reloading. Anyway, it does more than just set debug mode.
set -x FLASK_ENV development
Run It
The Development server
This is the output of the help string for the development server, note that it uses -h
for host
so you need to pass in --help
to see this output or you will get an error.
flask run --help
Public Server
The default server runs on localhost, but since I'm hosting the code on a raspberry pi sitting on the network somewhere but debugging it remotely, I need to run it on a public address.
flask run --host=<IP_ADDRESS>


Programming is the act of inputting literal and exact command instructions to a computer and expecting a certain output result. Therefore, programmers must constantly and systematically debug their work before being able to implement the correct results. This webpage is crafted as a project to complete my nanodegree from Udacity .By utilizing Andy Brown's Codepen , I can use this tool to implement my goal to practice, learn, document, and teach this course simultaneously.
The Web: the HTML NetworkThe Internet is the biggest, largest, most public and pervelent computer network on Earth. Users of the Internet use their browsers to request HTML documents to be sent to them and loaded on their computers. Servers on the Internet utilize their powerful processing capabilities to respond to these high volumes of requests by sending them the specifically requested HTML documents.
HTML Documents: What the Web is made ofHyper Text Markup Language is a language that developers use to create HTML documents so that client browsers can display them to the user whenever she downloads those pages from an HTTP server hosting the documents. They're made of texts & markups. Markups decide what the different texts should look like.
An HTML Document's Anatomy: Tags & ElementsAn HTML document is made up of tags and elements. Tags make up the elements. Elements can have either one tag (Void elements) or two tags. The way these tags and elements are constructed determine how the computer understands and thus executes your code to a desired and correct output
Blocks vs InlinesBlocks are elements that come in a form of an "invisible box" that comes after the line where the block element is written. On the contrary, Inlines are elements that don't have an invisible box after the written inline element; they remain in line.
Are Computers Stupid?Although computers can't literally be told how to seperate odd and even numbers from a list of thousand numbers like humans could, they most definitely will execute that request rather much faster than humans. The difference is that you can tell a human to "divide these numbers into an odd-and-even order," and she will painstakingly do the task after long hours, and possibly days of repetitive work, however, the programmer takes her time to code up an application, or a function within an app that's made to use abstractions and other techniques to sort out these two groups of separate numbers.
Thus I believe that computers are not stupid ironically, since it's the human programmer who programs the application and the user who uses it; both the programmer and user must build and utilize the program exactly the way it should work, so that the computer can understand and run the codes and commands it's being fed and ran into.

HTML Drag & Drop
In HTML5, drag and drop is part of the standard, and any element can be draggable.
Drag the disappointed cat into the rectangle.
To make an element draggable, we set the draggable attribute to true:

We also specify what should happen when the element is dragged.

In the example above, the ondragstart attribute calls a function, drag(event), that specifies what data to be dragged.
The dataTransfer.setData method sets the data type and the value of the dragged data:
function drag(ev) {
ev.dataTransfer.setData("text", ev.target.id); }
In this case, the data type is "text" and the value is the id of the draggable element.
The preventDefault prevents the browser default handling of the data (default is open as link on drop).
function allowDrop(ev) {
ev.preventDefault(); }
When the dragged data is dropped, a drop event occurs. In the example above, the ondrop attribute calls a function, drop(event):
function drop(ev) { ev.preventDefault(); var data = ev.dataTransfer.getData("text"); ev.target.appendChild(document.getElementById(data)); }
What is happening?
- Call preventDefault() to prevent the browser default handling of the data (default is open as link on drop)
- Get the dragged data with the dataTransfer.getData() method. This method will return any data that was set to the same type in the setData() method
- The dragged data is the id of the dragged element ("drag1")
- Append the dragged element into the drop element

by Kalina Wu, Ivan Storck, and Sarah Fischer
In our development accelerator, students are introduced to several tools and libraries to expand the abilities of their code. Kalina, one of our former JavaScript students, compiled a list of these tools and wanted to share it with other Code Fellows.
Ivan Storck, our JavaScript Development Accelerator instructor, used Kalina's list to draft up this helpful mind map:
General
Scaffolding Tools (for starting projects)
- Yeoman - Yeoman is a robust and opinionated client-side stack, comprising tools and frameworks that can help developers quickly build beautiful web applications.
Build Tools (automation)
- Grunt.js - The Grunt ecosystem is huge and it's growing every day. With literally hundreds of plugins to choose from, you can use Grunt to automate just about anything with a minimum of effort.
- Pint.js (Grunt helper) - Pint is a small, asynchronous, dependency-aware wrapper around Grunt, attempting to solve some of the problems that accompany a build process at scale.
- Gulp.js - Gulp's use of streams and code-over-configuration makes for a simpler and more intuitive build.
- Browserify.js (for browser) - Browserify is a development tool that allows us to write node.js-style modules that compile for use in the browser. Just like node, we write our modules in separate files, exporting external methods and properties using the module.exports and exports variables.
- Uglify.js - Uglify.js is a JavaScript parser / mangler / compressor / beautifier library for NodeJS.
Package Management Tools
- Homebrew (Mac OS) - Homebrew installs the stuff you need that Apple didn't.
- Apt (Ubuntu) - The apt-get command is a powerful command-line tool, which works with Ubuntu's Advanced Packaging Tool (APT) performing such functions as installation of new software packages, upgrade of existing software packages, updating of the package list index, and even upgrading the entire Ubuntu system.
- NPM - npm is the official package manager for Node.js.
- Bower - Bower is a package manager for the web.
Front End
MVC Frameworks
- Backbone.js - Backbone.js gives structure to web applications by providing models with key-value binding and custom events, collections with a rich API of enumerable functions, and views with declarative event handling. It connects it all to your existing API over a RESTful JSON interface.
- Ember.js - Ember makes Handlebars templates even better by ensuring your HTML stays up-to-date when the underlying model changes. To get started, you don't even need to write any JavaScript.
- Angular.js - AngularJS lets you extend HTML vocabulary for your application. The resulting environment is extraordinarily expressive, readable, and quick to develop.
Templates
- Handlebars.js - Handlebars provides the power necessary to let you build semantic templates effectively with no frustration. Mustache templates are compatible with Handlebars, so you can take a Mustache template, import it into Handlebars, and start taking advantage of the extra Handlebars features.
- Mustache.js (less built-out than Handlebars) - Mustache is a simple web template system with implementations available for ActionScript, C++, Clojure, CoffeeScript, ColdFusion, D, Erlang, Fantom, Go, Java, JavaScript, Lua, .NET, Objective-C, Pharo, Perl, PHP, Python, Ruby, Scala and XQuery.
- Jade - Jade is a node template engine designed primarily for server-side templating in node.js.
- Haml-js - Haml-js allows the Haml syntax to be used in a JavaScript project. It has most of the same functionality as the original Haml.
- Eco - Eco lets you embed CoffeeScript logic in your markup.
Testing
- Casper.js - CasperJS is a navigation scripting and testing utility for PhantomJS and SlimerJS written in Javascript.
- Zombie.js - Zombie.js is a lightweight framework for testing client-side JavaScript code in a simulated environment. No browser required.
Back End
Servers
- Express - Express is a web application framework for Node.
- Node - Node.js is a platform built on Chrome's JavaScript runtime for easily building fast, scalable network applications.
Databases
- MongoDB - MongoDB is an open-source document database, and the leading NoSQL database.
- Postgresql - PostgreSQL is a powerful, open source, object-relational database system.
- SQL - SQL is used to communicate with a database. According to the American National Standards Institute, it is the standard language for relational database management systems.
Architectural Style
- RESTful - Representational State Transfer is an architectural style consisting of a coordinated set of architectural constraints applied to components, connectors, and data elements, within a distributed hypermedia system.
Testing
- Cucumber.js - Cucumber.js takes the popular behavior-driven development tool and applies it to your JavaScript stack.
- Jasmine - Jasmine is a behavior-driven development testing framework for JavaScript. It does not rely on browsers, DOM, or any JavaScript framework. Thus it's suited for websites, Node.js projects, or anywhere that JavaScript can run.
- Mocha - Mocha is a feature-rich JavaScript test framework running on node.js and the browser, making asynchronous testing simple and fun.
- Q-Unit - Q-Unit is a powerful, easy-to-use JavaScript unit testing framework. It's used by the jQuery, jQuery UI and jQuery Mobile projects and is capable of testing any generic JavaScript code.
Assertion Libraries
- Chai - Chai is a BDD / TDD assertion library for node and the browser that can be delightfully paired with any javascript testing framework.
Functional Programming Tools
- Underscore.js - Underscore is a JavaScript library that provides a whole mess of useful functional programming helpers without extending any built-in objects.
- Lo-Dash - Lo-Dash is a utility library delivering consistency, customization, and performance.

--- layout: post authors: ["Greg Wilson"] title: "Plans for 2015: Lessons" date: 2014-12-03 time: "09:30:00" tags: ["Lessons"] ---
The previous three posts in this set looked at instructor training, workshop organization, and the twin challenges of mentorship and assessment. In this final one, I'll summarize the state of the changes we're making to our curriculum.
We described the new template for lessons back in October, and since then, a handful of people have been working to improve it and to extract our existing lessons from the 'bc' repository and convert them to the new format. The first step has taken longer than planned: we want to be sure we get the entire history of each lesson, so that people receive credit for the work they've done, and thats proving to be a slog.
The good news is, you can now see what the result will look like. Our novice lesson on SQL now lives in this repository, and you can view its rendered form in this GitHub pages site. There's still a lot to do—the learning objectives need to be cleaned up, the challenges all need meaningful names, and there's clearly lots of scope for improving the lesson's appearance—but the pieces are there.
You can also see what entirely new lessons will look like. This lesson (which is rendered here) takes a bibliography embedded in a spreadsheet and converts it to a single-table database so that we can ask questions like, "Who has co-authored papers with whom?" Along the way, we show learners how to use the shell, Python, Git, and SQL together, so the lessons serves as a good half-hour capstone at the end of a two-day workshop.
We obviously still have a lot of work to do, but I hope we're finally in sight of a system that will make it so easy for instructors to add their personal notes to our lessons that they will routinely do so. As I've argued elsewhere, that would be the start of a real revolution.
p.s. If you'd like to help finish the "bibliography in a spreadsheet" lesson, please file an issue, send a pull request, or just send an email—like our other lessons, it will need a maintainer.

Free-kick from Ireland's Hourihane sets Aston Villa on way to victory over Newcastle
Hourihane also provided Villa’s second goal for Anwar El Ghazi.
by AFPCONOR HOURIHANE GRABBED a goal and Jack Grealish shone on his comeback from injury for Aston Villa as Newcastle manager Steve Bruce’s return to his former club ended in a dreadful 2-0 Premier League defeat on Monday.
Goals from Hourihane and Anwar El Ghazi in the space of four first-half minutes eased their recent woes after a run of three straight defeats.
Grealish, sidelined for the 2-1 defeats at home to Liverpool and at Wolves with a thigh strain, again provided the spark Villa had been missing in those games.
Left-back Targett was the victim of a bizarre 20th-minute incident when he vomited on the pitch just after he had taken a throw-in – but after treatment and water the £15.6million summer signing from Southampton was able to continue.
Villa were always the more threatening side.
The first arrived in the 32nd minute as Grealish raced onto a raking through ball, only for the attacking midfielder to be blatantly pushed in the back by the covering DeAndre Yedlin a yard outside the area.
Four minutes later Villa doubled their lead, with Grealish again drawing a foul, although it appeared as if he had deliberately caught the outstretched leg of Federico Fernandez.
On this occasion, Hourihane curled a piercing low ball into the six-yard box, and with Newcastle’s defence leaden-footed, El Ghazi easily stabbed home his fourth goal of the season from three yards.
It prompted cries from the Villa fans of ‘Brucey, Brucey what’s the score?’ as the home faithful teased their former boss.
Despite Bruce playing all three substitutes, including strikers Andy Carroll and Dwight Gayle, his side were unable to find a way back into the game.

Rhodiola rosea |
(extract) |
This is a report on my first experience with Rodiola Rosea Extract. In the last ten years, my experience with entheogens include psilocybin, cannabis, MDMA, cocaine, alcohol, caffeine, tobacco, and Salvia divinorum. I am an experienced though now retired psychonaut, and my only habit that I currently am weeding out is Starbucks double shots for work. However, I found that with caffeine, for me, and possibly others, there's a point of diminishing return, where after too much caffeine in one day, my mind starts to simply withdraw and in my case, produce headaches. I enjoyed the boost I got for an hour or two from the rush of the double shot, but after several days of very little sleep and intense work loads, I started to seek an alternative to caffeine.
Enter Rodiola Rosea. This is a substance which apparently is similar to caffeine, but without the withdrawal headaches or what's termed asthenia (fatigue, decline in work capacity, trouble falling asleep, poor appetite, irritability, and headaches).
Here is my experience so far:
(T+2:00) I feel a slight boost in energy, a little fidgety almost, not sure if it's a placebo effect, but seems like I can breathe a little easier and noticed sharper vision twice, once when driving, and again when I sat down here.
(T+2:30) I do feel some effect from the supplements. it's a new experience so it's hard to pin point what it is that I'm feeling. but I do feel the urge to keep working, just like when I have a Starbucks double shot, which is very good considering I didn't have caffeine to feel this way, need to research that active ingredient
(T+4:00) I definitely feel some kind of change in my state. It's a little hard to describe, but it's like, having the motivation I get from caffeine, but without feeling edgy or irritable, still being able to stay in a calm state of mind, yet feeling like I have to do the next thing, and keep going. I also noticed my appetite is somewhat suppressed. I don't really have an urge to eat yet, though I should be.
It is now (T+6:15) and I definitely feel that something is keeping me going that is not caffeine. My mind is clear, yet not lethargic as I would be if it were two double shots by this time. Also to note, I feel calm like after five days of not having any coffee products. I read in a research paper that Rodiola Rosea also has a calming effect on the nervous system. I'm quite pleased with the discovery of this herbal extract and will observe further use to see how it affects my overall wellness over the next several weeks.

@particle4dev Hi, even on centralized exchange your order might not match if someone buys/sells before you. It's ok if user will receive the message that other order was cancelled/removed for some reason.
Next: if user wants to trade exactly KMD with BTC what is the reason for him to place KMD/LTC order? There are 2 possible use cases, let's assume that one has 200 KMD:
1. He wants to exchange 200 KMD to BTC or LTC and he doesn't care to which one exactly it'll be exchanged, he puts order...


Hi! This is Patrick. I acquired a degree in Computer Engineering from Texas A&M University in May 2017. I am working as an assistant in NetBot Laboratory at Texas A&M University. My current focus is developing software to enable that robots or vehicles could use camera images to achieve the goal of simultaneous localization and mapping. I am passionate about developing software, learning new technologies, and solving problems. I hope that I can utilize my skills to make a small impact. Please look around on my web to see some interesting projects that I had accomplished. Happy coding and hacking.

Automatic Map Initialization
Introduction
We, human beings, use our eyes to identify where we are. How do robots or autonomous vehicles to find their position in an unexplored environment by using only camera sensor? Visual simultaneous localization and mapping (visual SLAM) is one of the algorithms to achieve the goal. In the features-based SLAM, we use distinct features in two corresponding images as landmarks to compute how much distance we moved.
The project implements the automatic map initialization in ORB-SLAM. ORB-SLAM is the current state-of-the-art visual SLAM algorithm. The project goal is to automatically select a proper model to compute the progression distance based on different input scenes. In the two-view geometry, the model will be the homography matrix if the scene is dominated by planar objects whereas the model will be the fundamental matrix if the scene is dominated by non-planar objects. The implementation uses a score function to evaluate the model selection. After a proper model is selected, camera poses and the relative progression can be calculated correctly.
Results
ORB-SLAM is a feature-based SLAM algorithm. In order to track features correctly, the map initialization is a crucial step. The project goal is to automatically select a proper model (H or F) based on the corresponding input images.
We compute the homography matrix H and the fundamental matrix F, and calculate score functions (S_H and S_F). ORB-SLAM suggests a heuristic function R_H. If R_H are greater than 0.45, the scene is dominated by planar objects and the model should be the homography matrix H. Otherwise, the fundamental matrix F will be selected as the model.
Simulation Settings:
To verify the algorithm, we generate a world scene. Cameras (the triangular pyramids) and feature (the red dots) are placed in the 3-dimensional world coordinates. In this simulation, camera only performs a rotation and features are distributed in the same plane. We expected that the algorithm should selected H as the model.
Simulation Results:
The right side is our computed results. The model H is selected. This meets our expectation. We can also find the camera poses. The left side recovers the view of the camera from two positions.
Realistic Results:
We use a realistic example to verfiy the algorithm again. The features in the images are distributed on a plane. And, yes, our algorithm select the H model, which meets our expectation.
Simulation Settings:
In this simulation, the camera poses (the triangular pyramids) are co-centered and the features (the red dots) are distributed randomly.
Simulation Results:
The right side is our computed results. The model H is selected because camera only perform rotations. We can also find the camera poses. The left side recovers the view of the camera from two positions.
Realistic Results:
In this realistic example, the image pair is taken before and after a camera rotation. Features in the images are distributed randomly. Our algorithm select the H model, which meets our expectation.
Simulation Settings:
In this simulation, the features (the red dots) are distributed on a plane. However, the two triangular pyramids means that the camera has moved and rotated from the position one to the position two.
Simulation Results:
The right side is our computed results. The model H is selected because the features are planar. We can also find the camera poses. The left side recovers the view of the camera from two positions.
Realistic Results:
In this realistic example, the image pair is taken before and after camera rotates and translates. Though features in the images are distributed randomly, they are on the same plane. The model H should be selected, and our algorithm gets the same result.
Simulation Settings:
In this simulation, the features are non-planar and are distributed randomly. The two triangular pyramids means that the camera has moved and rotated from the position one to the position two..
Simulation Results:
The right side is our computed results. The model F is selected because the features are non-planar. We can also find the camera poses. The left side recovers the view of the camera from two different positions.
Realistic Results:
In this realistic example, the camera (the triangular pyramids) perform a rotation and a translation and the features are non-planar. The model F should be selected, and our algorithm gets the same result.

filename = string designating full path and filename to image.
width=width in pixels of each frame in the image. height=height in pixels of each frame in the image. first=the frame to start with (usually 0) count=how many frames you are using of the imagestrip |
|
While similar to LoadImage, the LoadAnimImage loads a single image that is made up of 'frames' of seperate images (presumably to be used as frames of a graphic animation).
Like the LoadImage command, this command returns a file handle - a unique number to denote the graphic. Use a variable (usually GLOBAL) to contain this number, as you will need it to actually DRAW the image with the DrawImage command. See LoadImage command for more details. The imagestrip itself consists of 2 or more frames, arranged in a single graphic image. There is no spaces between the frames, and each frame must be the same width and height. When loaded, the frames will be indexed in a left-to-right, top-to-bottom fashion, starting in the top left corner. For examples, look at the file kaboom.bmp or sparks.bmp included in the C:Program FilesBlitzBasicsamplesgraphics folder of your computer. There are some free utilities floating around to help you do this. When drawing the image to the screen with the DrawImage command, you specify which frame to draw with the frame parameter. To actually make your image animate, you'll need to cycle through the frames (like a flip book, cartoon, or any other video) quickly to give the illusion of motion. Our example will show you how to use one of the sample imagestrips and make it animate. While it may seem confusing, we are going to do some timer work as well as a little weird math. Please look over the example (if your like me, over and over :). Note: You may need to change the location of the file to suit your system. See also: LoadImage. |

ABOUT ME
I am a research scientist at Google. I am interested in the theoretical foundations of machine learning. I’m particularly excited about understanding when and why modern machine learning algorithms work (or do not work). While my PhD thesis was on explaining why deep networks generalize well, my other works includes when/why models fail outside of distribution, and when/why GANs converge to the desired saddle point.
Prior to this I graduated with a PhD from the Computer Science Department of Carnegie Mellon University (CMU). I was extremely fortunate to be advised by Zico Kolter. I completed my undergraduate studies in the Department of Computer Science and Engineering at the Indian Institute of Technology, Chennai, India. Here I was advised by Balaraman Ravindran with whom I worked in reinforcement learning.

Relic Watcher:
In all 4 directions a piece of Kaerun's Memoir is stored. If you're truly qualified, you'll know the contents of the book.
Place your hand on the reading desks with the memoirs, in the order of the story.
If the order of contents are correct, that desk will glow like a bride.
But if the order is incorrect, you will be expelled.
