I was contacted by Elizabeth Beauty Spa to perform a complete overhaul of the website and the company branding. The specifications of the project included creating a refreshed brand for the company, as well as all of the front-end web design and implementation. I started by creating a brand new color palette, based off a mood board inspired by relaxing lavender tones and earthy pumice. From there, we created a series of web pages with an emphasis on simplicity, clarity, and easy maintainability by the client.

abstract fun getNotaryWorkers(notaryService: Party): List<Party>
Returns the list of notary workers for given notaryService.
Notary service is an identity, which is used to notarize transactions. It must be listed in the network parameters, however, it may not have dedicated MemberInfo structure. Each notary service must have at least one associated worker.
Notary worker is an identity, where notarization requests are routed to. It must have dedicated MemberInfo structure, which points to corresponding notary service via notaryServiceParty property.
In case of converting a returned list to a string representation use another delimiter rather than "," or wrap each entry with a postfix and a prefix:
list.joinToString("|")
list.map { "[$it]" }.toString()
This allows to distinguish between each element of a map, as Party.toString returns comma separated values of CordaX500Name.
notaryService
- Notary service identity.
IllegalStateException
- If no workers found for given notary service.
Return
Non-empty list of identities for notary workers.

I have a Lean project sufficently deep in a filespace heierarchy that lean --make -M4000 sheaf_on_opens_total_glueing.lean
from the command line makes the console start scrolling. The only fix I know is to make the console window massive. There must be a more hygenic way to stop this from happening (on Ubuntu)
I often have the same problem and I haven't found a good way to deal with it without making the window massive
One thing you can do is pipe the output into less
(normally I do this when I expect there to be a lot of errors), which disables the feedback about which file is being built entirely
I am normally interested in the first error and not much more
that's another advantage to piping through less

Using the API¶
API objects are the primary way to get access to assets and events. CityIq
is the top level access
object. The API offers access to Locations, Events and Events.
Typically, you will construct CityIq
from a Config
. If a configuration is not specific,
the system will look for the file in default locations. You can also override individual configuration parameters
with keyword arguments to the constructor.
Metadata Access¶
Metadata, for both locations and assets, can be fetched with property accessors. The bounding box for the queries can
be set in the configuration, or on the CityIq
constructor.
The asset metadata properties are:
CityIq.assets
: All assetsCityIq.nodes
: Nodes, the parents for other assets on a poleCityIq.cameras
: All assetsCityIq.em_sensors
: ?CityIq.env_sensors
: Environmental sensors
The location metadata properties are:
CityIq.locations
: All locationsCityIq.walkways
:CityIq.parking_zones
:CityIq.traffic_lane
:
Events can be fetched with cityiq.api.CityIq.events()
Each of these acessor properties or functions returns a generator that generates objects of a specific type, one base class for each of Locations, Assets or Events:
Asset
Location
Event
bbox = '32.718987:-117.174244,32.707356:-117.154850'
c = CityIq(bbox=bbox) # Use default config, override bbox
# Get Locations
locations = list(c.locations)
# Get the assets at this location:
for location in locations:
do_something_with(location.assets

Inflector
¶The Inflector class takes a string and can manipulate it to handle word
variations such as pluralizations or camelizing and is normally accessed
statically. Example:
Inflector::pluralize('example')
returns “examples”.
You can try out the inflections online at inflector.cakephp.org.
Quick summary of the Inflector built-in methods and the results they output when provided a multi-word argument:
| Method | Argument | Output |
|---|---|---|
pluralize() |

| big_apple | big_apples | |
singularize() |
BigApples | BigApple |
| big_apples | big_apple | |
camelize() |

| big apple | BigApple | |
underscore() |
BigApples | big_apples |
| Big Apples | big apples | |
humanize() |
big_apples | Big Apples |
| bigApple | BigApple | |
classify() |
big_apples | BigApple |

Cake\Utility\Inflector::
singularize
($singular)¶Cake\Utility\Inflector::
pluralize
($singular)¶Both pluralize
and singularize()
work on most English nouns. If you need
to support other languages, you can use Inflection Configuration to
customize the rules used:
// Apples
echo Inflector::pluralize('Apple');
Note
pluralize()
may not always correctly convert a noun that is already in its plural form.
// Person
echo Inflector::singularize('People');
Note
singularize()
may not always correctly convert a noun that is already in its singular form.
Cake\Utility\Inflector::
camelize
($underscored)¶Cake\Utility\Inflector::
underscore
($camelCase)¶These methods are useful when creating class names, or property names:
// ApplePie
Inflector::camelize('Apple_pie')
// apple_pie
Inflector::underscore('ApplePie');
It should be noted that underscore will only convert camelCase formatted words. Words that contains spaces will be lower-cased, but will not contain an underscore.
Cake\Utility\Inflector::
humanize
($underscored)¶This method is useful when converting underscored forms into “Title Case” forms for human readable values:
// Apple Pie
Inflector::humanize('apple_pie');
Cake\Utility\Inflector::
classify
($underscored)¶Cake\Utility\Inflector::
dasherize
($dashed)¶Cake\Utility\Inflector::
tableize
($camelCase)¶When generating code, or using CakePHP’s conventions you may need to inflect table names or class names:
// UserProfileSetting
Inflector::classify('user_profile_settings');
// user-profile-setting
Inflector::dasherize('UserProfileSetting');
// user_profile_settings
Inflector::tableize('UserProfileSetting');
Cake\Utility\Inflector::
variable
($underscored)¶Variable names are often useful when doing meta-programming tasks that involve generating code or doing work based on conventions:
// applePie
Inflector::variable('apple_pie');
Cake\Utility\Inflector::
slug
($word, $replacement = '-')¶Slug converts special characters into latin versions and converting unmatched characters and spaces to dashes. The slug method expects UTF-8 encoding:
// apple-puree
Inflector::slug('apple purée');
Note
Inflector::slug()
has been deprecated since 3.2.7. Use Text::slug()
instead.
CakePHP’s naming conventions can be really nice - you can name your database
table big_boxes
, your model BigBoxes
, your controller
BigBoxesController
, and everything just works together automatically. The
way CakePHP knows how to tie things together is by inflecting the words
between their singular and plural forms.
There are occasions (especially for our non-English speaking friends) where you may run into situations where CakePHP’s inflector (the class that pluralizes, singularizes, camelCases, and under_scores) might not work as you’d like. If CakePHP won’t recognize your Foci or Fish, you can tell CakePHP about your special cases.
Cake\Utility\Inflector::
rules
($type, $rules, $reset = false)¶Define new inflection and transliteration rules for Inflector to use. Often, this method is used in your config/bootstrap.php:
Inflector::rules('singular', ['/^(bil)er$/i' => '\1', '/^(inflec|contribu)tors$/i' => '\1ta']);
Inflector::rules('uninflected', ['singulars']);
Inflector::rules('irregular', ['phylum' => 'phyla']); // The key is singular form, value is plural form
The supplied rules will be merged into the respective inflection sets defined in
Cake/Utility/Inflector
, with the added rules taking precedence over the core
rules. You can use Inflector::reset()
to clear rules and restore the
original Inflector state.


These instructions will hopefully assist you to start with a stock Xiaomi Poco F1, unlock the bootloader (if necessary), and then download the required tools as well as the very latest source code for LineageOS (based on Google’s Android operating system) for your device. Using these, you can build both a LineageOS installation zip and a LineageOS Recovery image and install them on your device.
It is difficult to say how much experience is necessary to follow these instructions. While this guide is certainly not for the extremely uninitiated, these steps shouldn’t require a PhD in software development either. Some readers will have no difficulty and breeze through the steps easily. Others may struggle over the most basic operation. Because people’s experiences, backgrounds, and intuitions differ, it may be a good idea to read through just to ascertain whether you feel comfortable or are getting over your head.

Git step. It performs a clone from the specified repository.
Use the Pipeline Syntax Snippet Generator to generate a sample pipeline script for the git step.
More advanced checkout operations require the checkout
step rather than the git
step.
Examples of the git
step include:
The git
step is a simplified shorthand for a subset of the more powerful checkout
step:
checkout([$class: 'GitSCM', branches: [[name: '*/master']], userRemoteConfigs: [[url: 'https://git-server/user/repository.git']]])
NOTE: The checkout
step is the preferred SCM checkout method.
It provides significantly more functionality than the git
step.
Use the Pipeline Syntax Snippet Generator to generate a sample pipeline script for the checkout step.
The checkout
step can be used in many cases where the git
step cannot be used.
Refer to the git plugin documentation for detailed descriptions of options available to the checkout step.
For example, the git
step does not support:
Checkout from the git plugin source repository using https protocol, no credentials, and the master branch.
The Pipeline Syntax Snippet Generator generates this example:
git 'https://github.com/jenkinsci/git-plugin'Example: Git step with https and a specific branch
Checkout from the Jenkins source repository using https protocol, no credentials, and a specific branch (stable-2.204). Note that this must be a local branch name like 'master' or 'develop'.
Branch names that are not supported by the git
step
Remote branch names, SHA-1 hashes, and tag names are supported by the general purpose checkout
step.
The Pipeline Syntax Snippet Generator generates this example:
git branch: 'stable-2.204', url: 'https://github.com/jenkinsci/jenkins.git'Example: Git step with ssh and a private key credential
Checkout from the git client plugin source repository using ssh protocol, private key credentials, and the master branch. The credential must be a private key credential if the remote git repository is accessed with the ssh protocol. The credential must be a username / password credential if the remote git repository is accessed with http or https protocol.
The Pipeline Syntax Snippet Generator generates this example:
git credentialsId: 'my-private-key-credential-id', url: 'git@github.com:jenkinsci/git-client-plugin.git'Example: Git step with https and changelog disabled
Checkout from the Jenkins source repository using https protocol, no credentials, the master branch, and changelog calculation disabled.
If changelog is false
, then the changelog will not be computed for this job.
If changelog is true
or is not set, then the changelog will be computed.
See the workflow scm step documentation for more changelog details.
The Pipeline Syntax Snippet Generator generates this example:
git changelog: false, url: 'https://github.com/jenkinsci/credentials-plugin.git'Example: Git step with https protocol and polling disabled
Checkout from the Jenkins platform labeler repository using https protocol, no credentials, the master branch, and no polling for changes.
If poll is false
, then the remote repository will not be polled for changes.
If poll is true
or is not set, then the remote repository will be polled for changes.
See the workflow scm step documentation for more polling details.
The Pipeline Syntax Snippet Generator generates this example:
git poll: false, url: 'https://github.com/jenkinsci/platformlabeler-plugin.git'

I'm determined to contribute to the advancement of cutting edge tools for musicians and producers.
I'd love to hear about your project and help you realize your vision!
Tell me more.My mission is to provide professional technical services to audio industry entrepreneurs, musicians and educators. I aim to bolster productivity and creativity in the medium of audio through the development of new tools and technologies.
My interests in programming have evolved over time. What has become a passion for combining music and technology was born out of a love for problem solving. I first began to see how powerful writing code could be in my engineering studies. I soon realized how much I enjoyed programming and especially relished the challenge of creating robust solutions which I could apply to other problems or which I could expand upon to solve more complex problems.
I earned a BSME from Worcester Polytechnic Institute. Along the way, I learned to apply programming and engineering principles to tackle interdisciplinary projects with diverse teams. I always enjoyed developing software to solve complex computational and engineering problems. Thus writing code has been an integral part of the engineering design process for me.


Idan Ofer’s Israel Corp. to Invest Up to $500 Million in Growth Stage Companies
Israel Corp. intends to focus on companies based in Israel and Europe, investing between $70 million and $100 million in each in return for equity
by Tzally GreenbergTel Aviv-listed holding company Israel Corp. Ltd. announced in a stock filing Monday its plans to invest between $350 million and $500 million in growth-stage companies in the fields of foodtech, agtech, health, and industry 4.0.
Israel Corp. intends to focus on companies based in Israel and Europe, investing between $70 million and $100 million in each in return for equity.
Referring to its chosen fields, Israel Corp. stated that by 2030, global demand for food will grow by 35%, in correlation with the growing population. As life expectancy continues to rise, the company anticipates a growing demand for at-home medical treatment and healthcare services.
The company also predicts that traditional industry will be changing and implementing industry 4.0 solutions, as skilled manual workers are becoming scarce and expensive, extreme weather conditions affect the supply chain, and cybersecurity threats are becoming more common.
Controlled by Israeli billionaire Idan Ofer, Israel Corp. focuses mainly on energy and chemicals and holds significant stakes in Israel Chemicals Ltd. (ICL) and oil refining company Bazan Group.


I’ve been hearing about React since I first started learning JavaScript, but I’ll admit I took one look at it and it scared me. I saw what looked like a bunch of HTML mixed with JavaScript and thought, isn’t this what we’ve been trying to avoid? What’s the big deal with React?
Instead, I focused on just learning vanilla JavaScript and working with jQuery in a professional setting. After a few frustrated, failed attempts to get started with React, I finally started to get it, and I began to see why I might want to use React instead of vanilla JS or jQuery.
I tried to condense everything I’ve learned into a nice introduction to share with you, so here it is.
Prerequisites
There are a few things you should know in advance before you start playing around with React. If you’ve never used JavaScript or the DOM at all before, for example, I would get more familiar with those before trying to tackle React.
Here are what I consider to be React prerequisites.
- Basic familiarity with HTML & CSS.
- Basic knowledge of JavaScript and programming.
- Basic understanding of the DOM.
- Familiarity with ES6 syntax and features.
- Node.js and npm installed globally.
Goals
- Learn about essential React concepts and related terms, such as Babel, Webpack, JSX, components, props, state, and lifecycle.
- Build a very simple React app that demonstrates the above concepts.
Here’s the source and a live demo of the end result.
What is React?
- React is a JavaScript library - one of the most popular ones, with over 100,000 stars on GitHub.
- React is not a framework (unlike Angular, which is more opinionated).
- React is an open-source project created by Facebook.
- React is used to build user interfaces (UI) on the front end.
- React is the view layer of an MVC application (Model View Controller)
One of the most important aspects of React is the fact that you can create components, which are like custom, reusable HTML elements, to quickly and efficiently build user interfaces. React also streamlines how data is stored and handled, using state and props.
We’ll go over all of this and more throughout the article, so let’s get started.
Setup and Installation
There are a few ways to set up React, and I’ll show you two so you get a good idea of how it works.
Static HTML File
This first method is not a popular way to set up React and is not how we’ll be doing the rest of our tutorial, but it will be familiar and easy to understand if you’ve ever used a library like jQuery, and it’s the least scary way to get started if you’re not familiar with Webpack, Babel, and Node.js.
Let’s start by making a basic index.html
file. We’re going to load in three CDNs in the head
- React, React DOM, and Babel. We’re also going to make a div
with an id called root
, and finally we’ll create a script
tag where your custom code will live.
<!DOCTYPE html>

<meta charset="utf-8" />
<title>Hello React!</title>

I’m loading in the latest stable versions of the libraries as of the time of this writing.
- React - the React top level API
- React DOM - adds DOM-specific methods
- Babel - a JavaScript compiler that lets us use ES6+ in old browsers
The entry point for our app will be the root
div element, which is named by convention. You’ll also notice the text/babel
script type, which is mandatory for using Babel.
Now, let’s write our first code block of React. We’re going to use ES6 classes to create a React component called App
.
class App extends React.Component {
//...
}
Now we’ll add the render()
method, the only required method in a class component, which is used to render DOM nodes.
class App extends React.Component {
render() {
return (
//...
);
}
}
Inside the return
, we’re going to put what looks like a simple HTML element. Note that we’re not returning a string here, so don’t use quotes around the element. This is called JSX
, and we’ll learn more about it soon.
class App extends React.Component {
render() {
return
Hello world!

}
}
Finally, we’re going to use the React DOM render()
method to render the App
class we created into the root
div in our HTML.
ReactDOM.render(<App />, document.getElementById('root'))
Here is the full code for our index.html
.
<!DOCTYPE html>

<meta charset="utf-8" />
<title>Hello React!</title>

Now if you view your index.html
in the browser, you’ll see the h1
tag we created rendered to the DOM.
Cool! Now that you’ve done this, you can see that React isn’t so insanely scary to get started with. It’s just some JavaScript helper libraries that we can load into our HTML.
We’ve done this for demonstration purposes, but from here out we’re going to use another method: Create React App.
Create React App
The method I just used of loading JavaScript libraries into a static HTML page and rendering the React and Babel on the fly is not very efficient, and is hard to maintain.
Fortunately, Facebook has created Create React App, an environment that comes pre-configured with everything you need to build a React app. It will create a live development server, use Webpack to automatically compile React, JSX, and ES6, auto-prefix CSS files, and use ESLint to test and warn about mistakes in the code.
To set up create-react-app
, run the following code in your terminal, one directory up from where you want the project to live. Make sure you have 5.2
or higher in Node.js.
npx create-react-app react-tutorial
Once that finishes installing, move to the newly created directory and start the project.
cd react-tutorial
npm start
Once you run this command, a new window will popup at localhost:3000
with your new React app.
If you look into the project structure, you’ll see a /public
and /src
directory, along with the regular node_modules
, .gitignore
, README.md
, and package.json
.
In /public
, our important file is index.html
, which is very similar to the static index.html
file we made earlier - just a root
div. This time, no libraries or scripts are being loaded in. The /src
directory will contain all our React code.
To see how the environment automatically compiles and updates your React code, find the line that looks like this in /src/App.js
:
To get started, edit `src/App.js` and save to reload.
And replace it with any other text. Once you save the file, you’ll notice localhost:3000
compiles and refreshes with the new data.
Go ahead and delete all the files out of the /src
directory, and we’ll create our own boilerplate file without any bloat. We’ll just keep index.css
and index.js
.
For index.css
, I just copy-and-pasted the contents of Primitive CSS into the file.  I just find it easier to work with.
Now in index.js
, we’re importing React, ReactDOM, and the CSS file.
import React from 'react'
import ReactDOM from 'react-dom'
import './index.css'
Let’s create our App
component again. Before, we just had an

, but now I’m adding in a div element with a class as well. You’ll notice that we use className
instead of class
. This is our first hint that the code being written here is JavaScript, and not actually HTML.
class App extends Component {
render() {
return (

Hello, React!

)
}
}
Finally, we’ll render the App
to the root as before.
ReactDOM.render(<App />, document.getElementById('root'))
Here’s our full index.js
. This time, we’re loading the Component
as a property of React, so we no longer need to extend React.Component
.
import React, { Component } from 'react'
import ReactDOM from 'react-dom'
import './index.css'
class App extends Component {
render() {
return (

Hello, React!

)
}
}
ReactDOM.render(<App />, document.getElementById('root'))
If you go back to localhost:3000
, you’ll see “Hello, React!” just like before. We have the beginnings of a React app now.
React Developer Tools
There is an extension called React Developer Tools that will make your life much easier when working with React. Download React DevTools for Chrome, or whatever browser you prefer to work on.
After you install it, when you open DevTools, you’ll see a tab for React. Click on it, and you’ll be able to inspect components as they’re written. You can still go to the Elements tab to see the actual DOM output. It may not seem like that much of a deal now, but as the app gets more complicated, it will become increasingly necessary to use.
Now we have all the tools and setup we need to actually begin working with React.
JSX: JavaScript + XML
As you’ve seen, we’ve been using what looks like HTML in our React code, but it’s not quite HTML. This is JSX, which stands for JavaScript XML.
With JSX, we can write what looks like HTML, and also we can create and use our own XML-like tags. Here’s what JSX looks like assigned to a variable.
const heading =
Hello, React

Using JSX is not mandatory for writing React. Under the hood, it’s running createElement
, which takes the tag, object containing the properties, and children of the component and renders the same information. The below code will have the same output as the JSX above.
const heading = React.createElement('h1', { className: 'site-heading' }, 'Hello, React!')
JSX is actually closer to JavaScript, not HTML, so there are a few key differences to note when writing it.
className
is used instead ofclass
for adding CSS classes, asclass
is a reserved keyword in JavaScript.- Properties and methods in JSX are camelCase -
onclick
will becomeonClick
. - Self-closing tags must end in a slash - e.g.

JavaScript expressions can also be embedded inside JSX using reactjsy braces, including variables, functions, and properties.
const name = 'Tania'
const heading =
Hello, {name}

JSX is easier to write and understand than creating and appending many elements in vanilla JavaScript, and is one of the reasons people love React so much.
Components
So far, we’ve created one component - the App
component. Almost everything in React consists of components, which can be class components or simple components.
Most React apps have many small components, and everything loads into the main App
component. Components also often get their own file, so let’s change up our project to do so.
Remove the App
class from index.js
, so it looks like this.
import React from 'react'
import ReactDOM from 'react-dom'
import App from './App'
import './index.css'
ReactDOM.render(<App />, document.getElementById('root'))
We’ll create a new file called App.js
and put the component in there.
import React, { Component } from 'react'
class App extends Component {
render() {
return (

Hello, React!

)
}
}
export default App
We export the component as App
and load it in index.js
. It’s not mandatory to separate components into files, but an application will start to get unwieldy and out-of-hand if you don’t.
Class Components
Let’s create another component. We’re going to create a table. Make Table.js
, and fill it with the following data.
import React, { Component } from 'react'
class Table extends Component {
render() {
return (

Name
Job

Charlie
Janitor

Mac
Bouncer

Dee
Aspiring actress

Dennis
Bartender

)
}
}
export default Table
This component we created is a custom class component. We capitalize custom components to differentiate them from regular HTML elements. Back in App.js
, we can load in the Table, first by importing it in:
import Table from './Table'
Then by loading it into the render()
of App
, where before we had “Hello, React!”. I also changed the class of the outer container.
import React, { Component } from 'react'
import Table from './Table'
class App extends Component {
render() {
return (

)
}
}
export default App
If you check back on your live environment, you’ll see the Table
loaded in.
Now we’ve seen what a custom class component is. We could reuse this component over and over. However, since the data is hard-coded into it, it wouldn’t be too useful at the moment.
Simple Components
The other type of component in React is the simple component, which is a function. This component doesn’t use the class
keyword. Let’s take our Table
and make two simple components for it - a table header, and a table body.
We’re going to use ES6 arrow functions to create these simple components. First, the table header.
const TableHeader = () => {
return (

Name
Job

)
}
Then the body.
const TableBody = () => {
return (

Charlie
Janitor

Mac
Bouncer

Dee
Aspiring actress

Dennis
Bartender

)
}
Now our Table
file will look like this. Note that the TableHeader
and TableBody
components are all in the same file, and being used by the Table
class component.
const TableHeader = () => { ... }
const TableBody = () => { ... }
class Table extends Component {
render() {
return (

<TableHeader />
<TableBody />

)
}
}
Everything should appear as it did before. As you can see, components can be nested in other components, and simple and class components can be mixed.
A class component must include
render()
, and thereturn
can only return one parent element.
As a wrap up, let’s compare a simple component with a class component.
const SimpleComponent = () => {
return
Example

}
class ClassComponent extends Component {
render() {
return
Example

}
}
Note that if the return
is contained to one line, it does not need parentheses.
Props
Right now, we have a cool Table
component, but the data is being hard-coded. One of the big deals about React is how it handles data, and it does so with properties, referred to as props, and with state. Now, we’ll focus on handling data with props.
First, let’s remove all the data from our TableBody
component.
const TableBody = () => {
return

}
Then let’s move all that data to an array of objects, as if we were bringing in a JSON-based API. We’ll have to create this array inside our render()
.
class App extends Component {
render() {
const characters = [
{
name: 'Charlie',
job: 'Janitor',
},
{
name: 'Mac',
job: 'Bouncer',
},
{
name: 'Dee',
job: 'Aspring actress',
},
{
name: 'Dennis',
job: 'Bartender',
},
]
return (

)
}
}
Now, we’re going to pass the data through to the child component (Table
) with properties, kind of how you might pass data through using data-
attributes. We can call the property whatever we want, as long as it’s not a reserved keyword, so I’ll go with characterData
. The data I’m passing through is the characters
variable, and I’ll put reactjsy braces around it as it’s a JavaScript expression.
return (

)
Now that data is being passed through to Table
, we have to work on accessing it from the other side.
class Table extends Component {
render() {
const { characterData } = this.props
return (

<TableHeader />
<TableBody characterData={characterData} />

)
}
}
If you open up React DevTools and inspect the Table
component, you’ll see the array of data in the property. The data that’s stored here is known as the virtual DOM, which is a fast and efficient way of syncing data with the actual DOM.
This data is not in the actual DOM yet, though. In Table
, we can access all props through this.props
. We’re only passing one props through, characterData, so we’ll use this.props.characterData
to retrieve that data.
I’m going to use the ES6 property shorthand to create a variable that contains this.props.characterData
.
const { characterData } = this.props
Since our Table
component actually consists of two smaller simple components, I’m going to pass it through to the TableBody
, once again through props.
class Table extends Component {
render() {
const { characterData } = this.props
return (

<TableHeader />
<TableBody characterData={characterData} />

)
}
}
Right now, TableBody
takes no parameters and returns a single tag.
const TableBody = () => {
return

}
We’re going to pass the props through as a parameter, and map through the array to return a table row for each object in the array. This map will be contained in the rows
variable, which we’ll return as an expression.
const TableBody = props => {
const rows = props.characterData.map((row, index) => {
return (

{row.name}
{row.job}

)
})
return
{rows}

}
If you view the front end of the app, all the data is loading in now.
You’ll notice I’ve added a key index to each table row. You should always use keys when making lists in React, as they help identify each list item. We’ll also see how this is necessary in a moment when we want to manipulate list items.
Props are an effective way to pass existing data to a React component, however the component cannot change the props - they’re read-only. In the next section, we’ll learn how to use state to have further control over handling data in React.
State
Right now, we’re storing our character data in an array in a variable, and passing it through as props. This is good to start, but imagine if we want to be able to delete an item from the array. With props, we have a one way data flow, but with state we can update private data from a component.
You can think of state as any data that should be saved and modified without necessarily being added to a database - for example, adding and removing items from a shopping cart before confirming your purchase.
To start, we’re going to create a state
object.
class App extends Component {
state = {}
}
The object will contain properties for everything you want to store in the state. For us, it’s characters
.
class App extends Component {
state = {
characters: [],
}
}
Move the entire array of objects we created earlier into state.characters
.
class App extends Component {
state = {
characters: [
{
name: 'Charlie',
// the rest of the data
},
],
}
}
Our data is officially contained in the state. Since we want to be able to remove a character from the table, we’re going to create a removeCharacter
method on the parent App
class.
To retrieve the state, we’ll get this.state.characters
using the same ES6 method as before. To update the state, we’ll use this.setState()
, a built-in method for manipulating state. We’ll filter the array based on an index
that we pass through, and return the new array.
You must use
this.setState()
to modify an array. Simply applying a new value tothis.state.property
will not work.
removeCharacter = index => {
const { characters } = this.state
this.setState({
characters: characters.filter((character, i) => {
return i !== index
}),
})
}
filter
does not mutate but rather creates a new array, and is a preferred method for modifying arrays in JavaScript. This particular method is testing an index vs. all the indices in the array, and returning all but the one that is passed through.
Now we have to pass that function through to the component, and render a button next to each character that can invoke the function. We’ll pass the removeCharacter
function through as a prop to Table
.
render() {
const { characters } = this.state
return (

)
}
Since we’re passing it down to TableBody
from Table
, we’re going to have to pass it through again as a prop, just like we did with the character data.
class Table extends Component {
render() {
const { characterData, removeCharacter } = this.props
return (

<TableHeader />
<TableBody characterData={characterData} removeCharacter={removeCharacter} />

)
}
}
Here’s where that index we defined in the removeCharacter()
method comes in. In the TableBody
component, we’ll pass the key/index through as a parameter, so the filter function knows which item to remove. We’ll create a button with an onClick
and pass it through.

{row.name}
{row.job}

<button onClick={() => props.removeCharacter(index)}>Delete</button>

The
onClick
function must pass through a function that returns theremoveCharacter()
method, otherwise it will try to run automatically.
Awesome. Now we have delete buttons, and we can modify our state by deleting a character.
I deleted Mac.
Now you should understand how state gets initialized and how it can be modified.
Submitting Form Data
Now we have data stored in state, and we can remove any item from the state. However, what if we wanted to be able to add new data to state? In a real world application, you’d more likely start with empty state and add to it, such as with a to-do list or a shopping cart.
Before anything else, let’s remove all the hard-coded data from state.characters
, as we’ll be updating that through the form now.
class App extends Component {
state = {
characters: [],
}
}
Now let’s go ahead and create a Form
component in a new file called Form.js
. We’re going to create a class component, and within we’ll use a constructor()
, which we haven’t done thus far. We’ll need the constructor()
to use this
, and to receive the props
of the parent.
We’re going to set the initial state of the Form
to be an object with some empty properties, and assign that initial state to this.state
.
import React, { Component } from 'react'
class Form extends Component {
constructor(props) {
super(props)
this.initialState = {
name: '',
job: '',
}
this.state = this.initialState
}
}
Our goal for this form will be to update the state of Form
every time a field is changed in the form, and when we submit, all that data will pass to the App
state, which will then update the Table
.
First, we’ll make the function that will run every time a change is made to an input. The event
will be passed through, and we’ll set the state of Form
to have the name
(key) and value
of the inputs.
handleChange = event => {
const { name, value } = event.target
this.setState({
[name]: value,
})
}
Let’s get this working before we move on to submitting the form. In the render, let’s get our two properties from state, and assign them as the values that correspond to the proper form keys. We’ll run the handleChange()
method as the onChange
of the input, and finally we’ll export the Form
component.
render() {
const { name, job } = this.state;
return (
<form>
Name
<input
type="text"
name="name"
value={name}
onChange={this.handleChange} />
Job
<input
type="text"
name="job"
value={job}
onChange={this.handleChange} />
</form>
);
}
export default Form;
In App.js
, we can render the form below the table.
return (

<Form />

)
Now if we go to the front end of our app, we’ll see a form that doesn’t have a submit yet. Update some fields and you’ll see the local state of Form
being updated.
Cool. Last step is to allow us to actually submit that data and update the parent state. We’ll create a function called handleSubmit()
on App
that will update the state by taking the existing this.state.characters
and adding the new character
parameter, using the ES6 spread operator.
handleSubmit = character => {
this.setState({ characters: [...this.state.characters, character] })
}
Let’s make sure we pass that through as a parameter on Form
.
<Form handleSubmit={this.handleSubmit} />
Now in Form
, we’ll create a method called submitForm()
that will call that function, and pass the Form
state through as the character
parameter we defined earlier. It will also reset the state to the initial state, to clear the form after submit.
submitForm = () => {
this.props.handleSubmit(this.state)
this.setState(this.initialState)
}
Finally, we’ll add a submit button to submit the form. We’re using an onClick
instead of an onSubmit
since we’re not using the standard submit functionality. The click will call the submitForm
we just made.
<input type="button" value="Submit" onClick={this.submitForm} />
And that’s it! The app is complete. We can create, add, and remove users from our table. Since the Table
and TableBody
were already pulling from the state, it will display properly.
If you got lost anywhere along the way, you can view the complete source on GitHub.
Pulling in API Data
One very common usage of React is pulling in data from an API. If you’re not familiar with what an API is or how to connect to one, I would recommend reading How to Connect to an API with JavaScript, which will walk you through what APIs are and how to use them with vanilla JavaScript.
As a little test, we can create an Api.js
file, and create a new App
in there. A public API we can test with is the Wikipedia API, and I have a URL endpoint right here for a random* search. You can go to that link to see the API - and make sure you have JSONView installed on your browser.
We’re going to use JavaScript’s built-in Fetch to gather the data from that URL endpoint and display it. You can switch between the app we created and this test file by just changing the URL in index.js
- import App from './Api';
.
I’m not going to explain this code line-by-line, as we’ve already learned about creating a component, rendering, and mapping through a state array. The new aspect to this code is componentDidMount()
, a React lifecycle method. Lifecycle is the order in which methods are called in React. Mounting refers to an item being inserted into the DOM.
When we pull in API data, we want to use componentDidMount
, because we want to make sure the component has rendered to the DOM before we bring in the data. In the below snippet, you’ll see how we bring in data from the Wikipedia API, and display it on the page
import React, { Component } from 'react'
class App extends Component {
state = {
data: [],
}
// Code is invoked after the component is mounted/inserted into the DOM tree.
componentDidMount() {
const url =
'https://en.wikipedia.org/w/api.php?action=opensearch&search=Seona+Dancing&format=json&origin=*'
fetch(url)
.then(result => result.json())
.then(result => {
this.setState({
data: result,
})
})
}
render() {
const { data } = this.state
const result = data.map((entry, index) => {
return
{entry}

})
return
{result}

}
}
export default App
Once you save and run this file in the local server, you’ll see the Wikipedia API data displayed in the DOM.
There are other lifecycle methods, but going over them will be beyond the scope of this article. You can read more about React components here.
*Wikipedia search choice may not be random. It might be an article that I spearheaded back in 2005.
Building and Deploying a React App
Everything we’ve done so far has been in a development environment. We’ve been compiling, hot-reloading, and updating on the fly. For production, we’re going to want to have static files loading in - none of the source code. We can do this by making a build and deploying it.
Now, if you just want to compile all the React code and place it in the root of a directory somewhere, all you need to do is run the following line:
npm run build
This will create a build
folder which will contain your app. Put the contents of that folder anywhere, and you’re done!
We can also take it a step further, and have npm deploy for us. We’re going to build to GitHub pages, so you’ll already have to be familiar with Git and getting your code up on GitHub.
Make sure you’ve exited out of your local React environment, so the code isn’t currently running. First, we’re going to add a homepage
field to package.json
, that has the URL we want our app to live on.
"homepage": "https://taniarascia.github.io/react-tutorial",
We’ll also add these two lines to the scripts
property.
"scripts": {
// ...
"predeploy": "npm run build",
"deploy": "gh-pages -d build"
}
In your project, you’ll add gh-pages
to the devDependencies.
npm install --save-dev gh-pages
We’ll create the build
, which will have all the compiled, static files.
npm run build
Finally, we’ll deploy to gh-pages
.
npm run deploy
And we’re done! The app is now available live at https://taniarascia.github.io/react-tutorial.
Conclusion
This article should have given you a good introduction to React, simple and class components, state, props, working with form data, pulling data in from an API, and deploying an app. There is much more to learn and do with React, but I hope you feel confident delving in and playing around with React yourself now.
Please let me know if anything was unclear, or if there’s anything else you’d like to see in this or a subsequent article.

Notts manager Neal Ardley forced to halt training as rain batters Midlands
Magpies session ended early as county issued with flood alerts
by Leigh CurtisNeal Ardley revealed how he had to call a halt to Notts County’s training session ahead of their clash against Barrow as the deluge of rain continues to batter the East Midlands.
Heavy downpours have left roads under water while flood warnings are also in place with forecasts predicting more downpours over the next 12 hours.
With Notts now at their new training bases at Holme Road, Ardley said training hasn’t been too badly affected by the weather which has seen rivers burst their banks.
But he said that he had no option to end his session early on Thursday morning due to standing water that made it impossible to pass the ball in certain areas.
“It’s funny because when we were at the university earlier in the season we were crying out for rain because the pitches were dry,” he said.
“Since we’ve moved over the road and the pitches aren’t as dry, it’s not stopped raining.
“It was a tough morning. To be fair the ground staff have worked very hard on the pitches at the new base, and while they’ve been heavy, we’ve been able to get training sessions on.
“Today the pitches were usable at 11am but then we got 25 minutes in and there were puddles everywhere.
“You couldn't pass the ball from A to B. We had to call it a day early.
“We got through the analysis and then we managed half-an-hour so we got something out of it.”


You can also copy and paste an entire full frame to any other place on the time-line by choosing the position the time-line to copy on the main time-line, then pressing Cntrl+Shift+C, then by going to the target location on the main time-line and pressing Cntrl+V. This even works if you are copying from a spot in the time-line that is not key-framed. This is often a fantastic way to start a new animation for a character...by finding an point in an animation you'd already created that comes somewhat close to the starting pose for the new animation. Just Cntrl+Shift+C to copy the initial pose from an already existing animation, and then create your new animation, make sure you are at time 0 (the very beginning) on the main time-line of the new animation, and then press Cntrl+V.

Undergraduate Reasearch Assistant
Lead Developer
I'm working as the lead developer for the Mu2e Experiment at the School of Physics and Astronomy, University of Minnesota. The goal is to create a particle accelerator to detect particles beyond the standard model. More than 40 institutions are involved and the first beam commissioning is expected to start in 2020 at Muon Campus, Fermilab. My contribution includes:
• Assemble and test components for detector to be placed in particle accelerator at Fermilab, Chicago. A $300M particle physics research project funded by United States Department of Energy to study Muon-to-Electron Conversion.
• Designed a set of GUIs with Python to help create the panels for the detector. The GUIs made sure that standard procedures were followed to make the panels with precision and perfection. The data from these procedures was collected in SQLite.
• Analyzed the collected data for hundreds of panels using SQL to make the detector efficient.
Bird Treatment Camp
It was Jaipur’s famous kite flying festival, Makar sakranti, 2010. A bird injured by flying manjhas, that invaded its territory of flying, fell right in front of me. I could not save the bird, but I swore right there not to ever fly a kite again in my life.
I joined Saviours, a NGO aimed at saving birds and snakes. Since then, for 5 straight years, I have organized a bird treatment camp with them. We save 80+ injured birds every year during the festival. Not only do I rescue and help treat the birds, I am also responsible for management and logistics of the initiative.

Isolate cluster nodes
Estimated reading time: 9 minutesWith Docker Enterprise, you can enable physical isolation of resources
by organizing nodes into collections and granting Scheduler
access for
different users. To control access to nodes, move them to dedicated collections
where you can grant access to specific users, teams, and organizations.
In this example, a team gets access to a node collection and a resource collection, and UCP access control ensures that the team members can’t view or use swarm resources that aren’t in their collection.
Note
You need a Docker Enterprise license and at least two worker nodes to complete this example.
To isolate cluster nodes:
- Create an
Ops
team and assign a user to it. - Create a
/Prod
collection for the team’s node. - Assign a worker node to the
/Prod
collection. - Grant the
Ops
teams access to its collection.
Create a team
In the web UI, navigate to the Organizations & Teams page to create a team named “Ops” in your organization. Add a user who isn’t a UCP administrator to the team. Learn to create and manage teams.
Create a node collection and a resource collection
In this example, the Ops team uses an assigned group of nodes, which it accesses through a collection. Also, the team has a separate collection for its resources.
Create two collections: one for the team’s worker nodes and another for the team’s resources.
- Navigate to the Collections page to view all of the resource collections in the swarm.
- Click Create collection and name the new collection “Prod”.
- Click Create to create the collection.
- Find Prod in the list, and click View children.
- Click Create collection, and name the child collection “Webserver”. This creates a sub-collection for access control.
You’ve created two new collections. The /Prod
collection is for the worker
nodes, and the /Prod/Webserver
sub-collection is for access control to
an application that you’ll deploy on the corresponding worker nodes.
Move a worker node to a collection
By default, worker nodes are located in the /Shared
collection.
Worker nodes that are running DTR are assigned to the /System
collection.
To control access to the team’s nodes, move them to a dedicated collection.
Move a worker node by changing the value of its access label key,
com.docker.ucp.access.label
, to a different collection.
- Navigate to the Nodes page to view all of the nodes in the swarm.
- Click a worker node, and in the details pane, find its Collection.
If it’s in the
/System
collection, click another worker node, because you can’t move nodes that are in the/System
collection. By default, worker nodes are assigned to the/Shared
collection. - When you’ve found an available node, in the details pane, click Configure.
- In the Labels section, find
com.docker.ucp.access.label
and change its value from/Shared
to/Prod
. - Click Save to move the node to the
/Prod
collection.
Note
If you don’t have a Docker Enterprise license, you will get the following error message when you try to change the access label: Nodes must be in either the shared or system collection without a license. Get a Docker Enterprise license.
Grant access for a team
You need two grants to control access to nodes and container resources:
- Grant the
Ops
team theRestricted Control
role for the/Prod/Webserver
resources. - Grant the
Ops
team theScheduler
role against the nodes in the/Prod
collection.
Create two grants for team access to the two collections:
- Navigate to the Grants page and click Create Grant.
- In the left pane, click Resource Sets, and in the Swarm collection, click View Children.
- In the Prod collection, click View Children.
- In the Webserver collection, click Select Collection.
- In the left pane, click Roles, and select Restricted Control in the dropdown.
- Click Subjects, and under Select subject type, click Organizations.
- Select your organization, and in the Team dropdown, select Ops.
- Click Create to grant the Ops team access to the
/Prod/Webserver
collection.
The same steps apply for the nodes in the /Prod
collection.
- Navigate to the Grants page and click Create Grant.
- In the left pane, click Collections, and in the Swarm collection, click View Children.
- In the Prod collection, click Select Collection.
- In the left pane, click Roles, and in the dropdown, select Scheduler.
- In the left pane, click Subjects, and under Select subject type, click Organizations.
- Select your organization, and in the Team dropdown, select Ops .
- Click Create to grant the Ops team
Scheduler
access to the nodes in the/Prod
collection.
The cluster is set up for node isolation. Users with access to nodes in the
/Prod
collection can deploy Swarm services
and Kubernetes apps, and their workloads
won’t be scheduled on nodes that aren’t in the collection.
Deploy a Swarm service as a team member
When a user deploys a Swarm service, UCP assigns its resources to the user’s default collection.
From the target collection of a resource, UCP walks up the ancestor collections
until it finds the highest ancestor that the user has Scheduler
access to.
Tasks are scheduled on any nodes in the tree below this ancestor. In this example,
UCP assigns the user’s service to the /Prod/Webserver
collection and schedules
tasks on nodes in the /Prod
collection.
As a user on the Ops
team, set your default collection to /Prod/Webserver
.
- Log in as a user on the
Ops
team. - Navigate to the Collections page, and in the Prod collection, click View Children.
- In the Webserver collection, click the More Options icon and select Set to default.
Deploy a service automatically to worker nodes in the /Prod
collection.
All resources are deployed under the user’s default collection,
/Prod/Webserver
, and the containers are scheduled only on the nodes under
/Prod
.
- Navigate to the Services page, and click Create Service.
- Name the service “NGINX”, use the “nginx:latest” image, and click Create.
- When the nginx service status is green, click the service. In the details view, click Inspect Resource, and in the dropdown, select Containers.
-
Click the NGINX container, and in the details pane, confirm that its Collection is /Prod/Webserver.
- Click Inspect Resource, and in the dropdown, select Nodes.
-
Click the node, and in the details pane, confirm that its Collection is /Prod.
Alternative: Use a grant instead of the default collection
Another approach is to use a grant instead of changing the user’s default
collection. An administrator can create a grant for a role that has the
Service Create
permission against the /Prod/Webserver
collection or a child
collection. In this case, the user sets the value of the service’s access label,
com.docker.ucp.access.label
, to the new collection or one of its children
that has a Service Create
grant for the user.
Deploy a Kubernetes application
Starting in Docker Enterprise Edition 2.0, you can deploy a Kubernetes workload to worker nodes, based on a Kubernetes namespace.
- Convert a node to use the Kubernetes orchestrator.
- Create a Kubernetes namespace.
- Create a grant for the namespace.
- Link the namespace to a node collection.
- Deploy a Kubernetes workload.
Convert a node to Kubernetes
To deploy Kubernetes workloads, an administrator must convert a worker node to
use the Kubernetes orchestrator.
Learn how to set the orchestrator type
for your nodes in the /Prod
collection.
Create a Kubernetes namespace
An administrator must create a Kubernetes namespace to enable node isolation for Kubernetes workloads.
- In the left pane, click Kubernetes.
- Click Create to open the Create Kubernetes Object page.
-
In the Object YAML editor, paste the following YAML.
apiVersion: v1 kind: Namespace metadata: Name: ops-nodes
- Click Create to create the
ops-nodes
namespace.
Grant access to the Kubernetes namespace
Create a grant to the ops-nodes
namespace for the Ops
team by following the
same steps that you used to grant access to the /Prod
collection, only this
time, on the Create Grant page, pick Namespaces, instead of
Collections.
Select the ops-nodes namespace, and create a Full Control
grant for the
Ops
team.
Link the namespace to a node collection
The last step is to link the Kubernetes namespace the /Prod
collection.
- Navigate to the Namespaces page, and find the ops-nodes namespace in the list.
-
Click the More options icon and select Link nodes in collection.
- In the Choose collection section, click View children on the Swarm collection to navigate to the Prod collection.
- On the Prod collection, click Select collection.
-
Click Confirm to link the namespace to the collection.
Deploy a Kubernetes workload to the node collection
- Log in in as a non-admin who’s on the
Ops
team. - In the left pane, open the Kubernetes section.
- Confirm that ops-nodes is displayed under Namespaces.
-
Click Create, and in the Object YAML editor, paste the following YAML definition for an NGINX server.
apiVersion: v1 kind: ReplicationController metadata: name: nginx spec: replicas: 1 selector: app: nginx template: metadata: name: nginx labels: app: nginx spec: containers: - name: nginx image: nginx ports: - containerPort: 80
- Click Create to deploy the workload.
-
In the left pane, click Pods and confirm that the workload is running on pods in the
ops-nodes
namespace.
