Contributing
Colour is open source and we happily welcome contributions. This guide will give you an overview on how to contribute.
There are many ways to help:
- Reporting a defect, proposing a new feature or enhancement or commenting existing issues on the Issue Tracker
- Contributing new code by implementing new features or adding examples, for some ideas you can take a look at the issues with the Enhancement and Feature labels or the v9.9.9 milestone.
- Maintaining the existing code base, improving the code style and quality, improving the coverage, updating the documentation, fixing bugs, addressing TODOs, etc... Issues with the Defect or Enhancement labels are a good place to start.
- Improving the Jupyter Notebooks, we aim to provide a good scientific support to the API and there is still a lot to do.
- Improving siblings packages:
- Participating in discussions on the Mailing List.
Github hosts a First Contributions repository with good information for new comers.
Reporting Issues
The three major issue types one can report on the issue tracker are the following: Defect, Enhancement and Feature.
We currently use a large set of labels to categorise issues:
-
Defect:
Used for any kind of defect reported.
- Critical: Used for issues either rendering the software unusable, causing loss of data, or preventing people to work. These issues need to be fixed immediately.
- Major: Used for issues which have significant consequences on the ability of people to work but do not lead to the whole API being unusable.
- Normal: Used for issues affecting one piece of functionality. Those are usually self-contained and don't impact the overall functionality of the API.
- Minor: Used for cosmetic issues that don't prevent the API to run properly.
- Enhancement: Used for an enhancement of an existing feature, can also be used for new feature suggestion, although Feature label should be preferred.
- Feature: Used for a new feature, functionality suggestion.
- API: Used for issues related to the API.
- Discarded: Used for a discarded / canceled issue.
- Discussion: Used to discuss any subject, those issues often turn into features or enhancement.
- Distribution: Used to discuss distribution and packaging of the API.
- Documentation: Used for issues related to the documentation.
- Duplicate: Used for a duplicate issue.
- Examples: Used for issues related to the examples.
- Postponed: Used for an issue postponed for a future milestone.
- Task: Used for a task not directly related to pure programming.
- Good First Issue: Used for an issue appropriate for a first time contribution.
- Help Wanted: Used for an issue appropriate for a first time contribution but likely harder than a Good First Issue one.
- Hacktoberfest: Used for an issue relevant to Digital Ocean's Hacktoberfest.
Defects
You encountered a problem while using Colour, please consider reporting it on the Issue Tracker.
The first thing to do, is to check if there are any existing issues describing your problem, if there is one, you are welcome commenting into it and provide more details. However, please avoid creating duplicates, they add noise to the issue tracker and we will have to label them as Duplicate and close them.
When reporting a defect please provide the following details if possible and makes sense to do so:
If you are reporting an exception, please provide the complete traceback, it will tremendously help us understand what happened.
Features & Enhancements
If you would like a new feature to be supported or an enhancement of an existing feature, don't hesitate to link any resources or references you feel like would help its implementation: publications, wikipedia article, etc...
If there is an implementation existing in another language, we will be most likely be able to port it although the licence must be compatible with the New BSD License terms.
We are also running Matlab, so don't hesitate to provide snippets for it if you have functions you would like to be ported.
Contributing Code
Assuming you have something to work on, you will have to get the code and follow the guidelines.
Development for Colour
Here is a succinct overview of the steps you will most likely go through:
- Fork the Colour repository.
- Activate Travis-CI for your fork so that the tests suite is run when you push your changes.
- Clone the repository locally to your workspace:
git clone git@github.com:$USER/colour.git
- Connect your clone to the original upstream repository by adding it as a remote:
git remote add upstream git@github.com:colour-science/colour
- You should now have two remotes:
git remote -v origin https://github.com/$USER/colour (fetch) origin https://github.com/$USER/colour (push) upstream https://github.com/colour-science/colour (fetch) upstream https://github.com/colour-science/colour (push)
- Pull the latest changes from upstream:
git checkout master git pull upstream master
- Create a branch for your contribution:
git checkout -b feature/mie_scattering The core developers are using the `git flow branching model <http://nvie.com/posts/a-successful-git-branching-model/>`_ for most of the development tasks and since the branch name appears in the commit message and for consistency, please use the following branch prefixes: - Feature branch prefix: **feature/** - Release branch prefix: **release/** - Hotfix branch prefix: **hotfix/**
- Check if the unit tests and doctests are running properly.
- flake8 is currently set to error if anything incorrect is found, thus we advice that you run it before committing and pushing your code to origin, your own fork.
- Commit your changes:
git add mie_scattering.py git commit -m 'Implement "Mie Scattering" support.'
- Push your changes back to origin, your own fork:
git push origin feature/mie_scattering
Code Reviews
Your pull request will be reviewed by the maintainers and any other developer interested in the project.
Every single developer has his code reviewed, this is a natural process helping to raise the codebase quality while having a friendly discussion. Comments will be made on various aspects such as the documentation and references, the code style and its implementation. Those can be discouraging, although they are not meant to criticize but aim at improving the quality of your submission. We all learn from that process and the project ultimately benefits from them.
Guidelines
Most of the conventions used in Colour are the same than NumPy, SciPy and scikit-image.
Overview
We follow the Google Python Style Guide and especially the Python Language Rules although with the main exception being the docstrings / documentation formatted with Numpy Docstrings Style.
The code has to be PEP 8 compliant although but before anything else, it needs to be consistent with the Colour Science litterature:
For example, the base CIE colourspace is CIE XYZ with upper case notation. It can be converted to chromaticity coordinates xy with lower case notation. If we were to follow the PEP 8 recommendations, we would have written a conversion definition as follows:
def xyz_to_xy(xyz): x, y, z = np.ravel(xyz) x, y = x / (x + y + z), y / (x + y + z) return x, y
Abstracting the fact the above definition is totally undocumented, it can be confusing to understand when we are referencing big X tristimulus value or little x chromaticity coordinate.
For those cases, and there are legions of them in Colour Science, we have decided to go for clarity and consistency with the literature for the object names:
def XYZ_to_xy(XYZ): X, Y, Z = np.ravel(XYZ) x, y = X / (X + Y + Z), Y / (X + Y + Z) return x, y
When the reference is using upper case named variables, we try to follow the same convention, it is unfortunately not PEP 8 compliant but has the benefit of a much easier comparison between the implementation and the reference.
We suggest that contributors follow the same rule.
Python Language Rules
- All the code must be covered by unit tests and doctests.
- All the code must be documented to the same standard than NumPy, SciPy and scikit-image.
- All the code must be checked with the static analysis tool of your choice (we use PyCharm extensively), flake8, Landscape and Scrutinizer
- No pull request should be merged without being reviewed and ensuring that the tests suite pass in Travis-CI.
- Examples should be provided for new features.
Python Style Rules
-
Ensure consistency with Colour Science literature first.
-
Ensure PEP 8 compliance.
-
Try using a close to Latex syntax for variables names so that they are easier to compare to the reference.
For instance, a variable defined \(D_{uv}\) in a paper would be defined as D_uv in the code, \(L^*\) as Lstar and \(X_{ab}^{\prime}\) as Xp_ab.
-
Try using uppercase for author names in definitions:
def CCT_to_xy_Kang2002(CCT):
- Please use British English words instead of American English ones as the CIE does, the most important of all being colour instead of color. You can consult the CIE Termlist if any doubts.
- Import NumPy as follows:
import numpy as np
- Doctests may need ellipsis, don't rely on global nose settings and specify it using the dedicated pragma as follows:
>>> Lab = np.array([100.00000000, -7.41787844, -15.85742105]) >>> Lab_to_LCHab(Lab) # doctest: +ELLIPSIS array([ 100. , 17.5066479...,<PHONE_NUMBER>...])
-
Numbers in the API are usually rounded as follows:
- Dataset numbers are kept as is if they are from a known reference or rounded to 15 digits if computed with the API (spectral distributions, chromaticity coordinates, etc...).
- Unit tests and doctests input numbers are kept as is if they are from a reference or rounded to 8 digits if computed with the API.
- Unit tests output numbers are rounded to 8 digits.
- Doctests output numbers trimmed with ellipsis to 7 digits.
-
We recommend a set of values for use with examples and unit tests. A Gist is available with the generating code.
Priority should be given for CIE Standard Illuminant D Series D65 computed values:

- Some commonly used dataset elements have aliases like 'cie_2_1931' for 'CIE 1931 2 Degree Standard Observer'. Those are provided for convenience and are reserved for external usage, please use the long form for consistency across the API.
- In the same way as above, some computation methods are using a title case like 'Ohno 2013', while the mapping object holding them is case insensitive, please use the title case form for consistency across the API.
- Some very big lines sometimes cannot be wrapped (doctests, html links), you can use the # noqa pragma in those cases, although do it in last resort, we have already too much of them.
- Avoid / to wrap lines, prefer using the parenthesis ().
- The code formatting is performed using Yapf. You can invoke it recursively on a directory as follows:
find . -type f -name '*.py' -exec yapf -i {} \;
- Inline comments must have two spaces.
- Ensure that you have blank line at the end of the files.
- Ensure that trailing whitespaces are stripped.
- Prefix unused variable with an underscore:
_L, a, b = tsplit(Lab)

Commits
A good committing strategy implies that separated commits should be done for any particular changes: One should not commit multiple bugs fixes or large change sets at once.
This unnecessarily increase complexity for any code merge or rollbacks needs and prevent a grainier control over the version control. One exception to this rule is for the initial design steps when creating a new sub-package or feature (please consider squashing the commits), but once the said sub-package is in production, a regular committing strategy should be applied.
Commit messages need to use imperative syntax, the first commit line must be a quick description of the modification content finished by a punctuation mark and can be followed by a detailed description separated by one line break. If the commit fixes a particular issue in the issue tracker, it's advised to state it in the commit message using the following syntax: Closes #32.
Yes: Implement "Yoshi Ohno" correlated colour temperature calculation. Closes #32. This implementation allows for a more precise correlated colour temperature calculation by using a two solutions hybrid approach.
No: Coded new cool cct method
Feature Branches & History
History should never be re-written, although while working on your local feature branch, you may want to provide a cleaner commits history before submitting a pull request. It is perfectly fine to modify your local branch as you wish.
However, if you need to change history on a public and used feature branch, please inform the Colour developers in order to avoid commit losses or a merging disaster.

$ invoke tag
A typical tag message for a Colour version is as follows:
Create Colour v0.3.11 version.
In the eventuality where the tag creation failed, it might be created manually as follows:$ git tag -a -m "Create Colour v0.3.11 version."


Free time is the most important value to me. You may be thinking, "Wow, Kevin must be such a slacker", but I don't mean it in that way. While some people may feel accomplished after finishing a packed schedule at the end of the day, I'm content with just having a bit of free time in my day to unwind and do what I want to do. I consider myself an introvert, and introverts value their "alone time" highly. It's highly beneficial for my mental sanity and it gives me time to reflect on what I did during the day.

The last time someone asked for my advice was for recommendations on what anime to watch, because my tastes are a bit unique when it comes to anime I guess. I don't follow American shows like Game of Thrones or How I Met Your Mother, and prefer to keep up with Japanese anime instead.

CKD Risk Calculator
"Population 1" refers to patients over 70 years of age and can be analyzed in comparison with the reference set of all diabetes patients.


Introduction
The CC Catalog project handles the flow of image metadata from the source or provider and loads it to the database, which is then surfaced to the CC search tool. The workflows are set up for each provider to gather metadata about CC licensed images. These workflows are handled with the help of Apache Airflow. Airflow is an open source tool that helps us to schedule and monitor workflows.

monitor workflows . It provides an easy to use UI that makes managing tasks
easy. In Airflow, the tasks we want to schedule are organised in DAGs
(Directed Acyclic Graphs). DAGs consist of a collection of tasks, and a
relationship defined among these tasks, so that they run in an organised
manner. DAGs files are standard python files that are loaded from the defined
DAG_FOLDER
on a host. Airflow selects all the python files in the
DAG_FOLDER
that have a DAG instance defined globally, and executes them to
create the DAG objects.
CC Catalog Workflow
In the CC catalog, Airflow is set up inside a docker container along with other
services . The loader and provider workflows are inside the dags
directory in
the repo dag folder. Provider workflows are set up to pull metadata
about CC licensed images from the respective providers , the data pulled is
structured into a standardised format and written into a TSV (Tab Separated
Values) file locally. These TSV files are then loaded into S3 and then finally
to PostgreSQL DB by the loader workflow.
Provider API workflow
The provider workflows are usually scheduled in one of two time frequencies, daily or monthly.
Providers such as Flickr or Wikimedia Commons that are filtered using the date parameter are usually scheduled for daily jobs. These providers have a large volume of continuously changing data, and so daily updates are required to keep the data in sync.
Providers that are scheduled for monthly ingestion are ones with a relativley low volume of data, or for which filtering by date is not possible. This means we need to ingest the entire collection at once. Examples are museum providers like the Science museum UK or Statens Museum for Kunst. We don’t expect museum providers to change data on a daily basis.
The scheduling of the DAGs by the scheduler daemons depends on a few parameters.
start_date
- it denotes the starting date from which the task should begin running.schedule_interval
- it denotes the interval between subsequent runs, it can be specified with airflow keyword strings like “@daily”, “@weekly”, “@monthly”, “@yearly” other than these we can also schedule the interval using cron expression.
Example: Cleveland museum is currently scheduled for a monthly crawl with a
starting date as 2020-01-15
. cleveland_museum_workflow
Loader workflow
The data from the provider scripts are not directly loaded into S3. Instead, they are stored in a TSV file on the local disk, and the tsv_postgres workflow handles loading of data to S3, and eventually PostgreSQL. The DAG starts by calling the task to stage the oldest tsv file from the output directory of the provider scripts to the staging directory. Next, two tasks run in parallel, one loads the tsv file in the staging directory to S3 , while the other creates the loading table in the PostgreSQL database. Once the data is loaded to S3 and the loading table has been created, the data from S3 is loaded to the intermediate loading table and then finally inserted into the image table. If loading from S3 fails the data is loaded to PostgreSQL from the locally stored tsv file. When the data has been successfully transferred to the image table, the intermediate loading table is dropped and the tsv files in the staging directory are deleted. If the copying the tsv files to S3 fails or then those files are moved to the failure directory for future inspection.

April 13th - 15th
Sure, you should definitely attend! Whether you have written lots of code or just have a creative soul, this hackathon needs you! In true hackathon spirit all students are very friendly and willing to help each other out.
Yes, we’re not kidding you. Thanks to our sponsors we will provide free food, swag, snacks, drinks and a place for you to sleep at the hackathon. Plus, there will be mentors, workshops and judges only for the sake of YOU.
You have the fantastic opportunity to learn new stuff, try out your skills and make new friends. Isn't that just great? Everyone will be a winner!... Okay, we will also have some awesome prizes.
No. That's not fair. You can come up with ideas, but not build them. You are of course allowed to use libraries, frameworks and templates for your hacks.
AUHack has been home to a wide variety of projects, from amazing hardware projects to the coolest VR Games and the most useful services and apps.
We always have a wide spectrum of hardware available, provided by our sponsors and happily administered by our knowledgeable wizards. A detailed list will be available as we get closer to the event!
No. You are more than welcome to make a team before the hackathon, but loads of people come without a team. We will help everyone find a team Friday night. We recommend groups of 4-5 persons, but anything is allowed.
Right here! Once you've filled out your application, we will accept it within a few days, and you'll have to fill out a confirmation form, so make sure to check your e-mail after applying!
You might think that a hackathon is for programmers only, but that’s not true. Technology and code is one thing – creative minds, bright insights and strategic eyes are another. So, as long as you are a student above 18 years old, you are more than welcome – no matter what university or study program you attend. Actually, we believe that the more different people we are, the better.
We will unfortunately not provide travel reimbursement this year.
Laptop, cellphone and chargers aswell as a sleeping bag, pillow, toiletries, clothes and a well-rested and open mind. If you want to hack on hardware, you might need to bring it yourself. What you won't need to bring is a pre-determined team, an idea for a hack, nor food and drinks. Also, there is absolutely no reason to bring bad mood.
AUHack will start in the evening of Friday at 16.30 and end Sunday at 16.00. All work eligible for prizes must be worked on and completed during this period of time and can't be prepared from home. Throughout the hackathon inspiring events, talks and mentoring sessions will be hosted. For a more detailed schedule see below.
There will be rooms to sleep in. You will have to bring your own bedroll, sleeping bag and pillows though.
Please take a look at
auhack.org/travel. We have written down some options for you.
The address is:
Finlandsgade 21, 8200 Aarhus N

Tim has an interesting post
here about dealing with semantic changes in existing interfaces on Web
Services (continuing from his posts here,
here,
and here).
I found this particularly interesting because we followed a very similar
approach on our last project.
In our case, we had a set of existing operations on a service with an
existing client using it, and needed to extend it with new operations. That was
no problem. However, during development we noticed that due to changes in a
backend LOB application our services connected with a new field was needed some
of the original operations. In particular, we needed the client to let us know
on what TimeZone (or rather what the time shift from UTC) to use when
registering the time some operations occurred. However, we required the original
client didn't change.
What we ended up doing was basically making the new TimeZone field optional,
and then introducing logic on the operations that checked if it was missing. If
it was, instead of simply assuming a global default value, we actually queried
our security configuration and extracted a default value for this field that was
specific to the client making the call. This was possible because the
services were using WS-Security for authenticating the caller. This way, we
could actually set especific default values for other clients if needed. It
worked very nicely overall and was remarkably easy to put in place.
Some of you might be wondering how we dealt with DST: We didn't. A explicit
decision from the business side was made not to support it because of some
complexity in the business side of things, and particularly because it would've
required clients in other countries to make changes to existing
infrastructure and the benefits just were not worth it. One thing we did learn
from that experience was that handling date and time fields in webservices where
consumers and service-providers are on different countries and time zones can be
easily get quite tricky, and that the way .NET handles
dates
on WebServices does not make things any easier.

In object-oriented programming, a class is an extensible program-code-template for creating objects, providing initial values for state (member variables) and implementations of behavior (member functions or methods).
In practice, we often need to create many objects of the same kind, like users, or goods or whatever.
As we already know from the chapter <info:constructor-new>, `new function` can help with that.
But in the modern JavaScript, there's a more advanced "class" construct, that introduces great new features which are useful for object-oriented programming.
## The "class" syntax
The basic syntax is:
```js
class MyClass {
// class methods
constructor() { ... }
method1() { ... }
method2() { ... }
method3() { ... }
...
}
Then use new MyClass()
to create a new object with all the listed methods.
The constructor()
method is called automatically by new
, so we can initialize the object there.
For example:
```js run class User { constructor(name) { this.name = name; }
sayHi() { alert(this.name); } }
// Usage: let user = new User(“John”); user.sayHi(); ```
When new User("John")
is called:
constructor
runs with the given argument and assigns it to this.name
.…Then we can call object methods, such as user.sayHi()
.
```warn header=“No comma between class methods” A common pitfall for novice developers is to put a comma between class methods, which would result in a syntax error.
The notation here is not to be confused with object literals. Within the class, no commas are required. ```
So, what exactly is a class
? That’s not an entirely new language-level entity, as one might think.
Let’s unveil any magic and see what a class really is. That’ll help in understanding many complex aspects.
In JavaScript, a class is a kind of function.
Here, take a look:
```js run class User { constructor(name) { this.name = name; } sayHi() { alert(this.name); } }
// proof: User is a function ! alert(typeof User); // function /! ```
What class User {...}
construct really does is:
User
, that becomes the result of the class declaration. The function code is taken from the constructor
method (assumed empty if we don’t write such method).sayHi
, in User.prototype
.After new User
object is created, when we call its method, it’s taken from the prototype, just as described in the chapter info:function-prototype. So the object has access to class methods.
We can illustrate the result of class User
declaration as:
Here’s the code to introspect it:
```js run class User { constructor(name) { this.name = name; } sayHi() { alert(this.name); } }
// class is a function alert(typeof User); // function
// …or, more precisely, the constructor method alert(User === User.prototype.constructor); // true
// The methods are in User.prototype, e.g: alert(User.prototype.sayHi); // the code of the sayHi method
// there are exactly two methods in the prototype alert(Object.getOwnPropertyNames(User.prototype)); // constructor, sayHi ```
Sometimes people say that class
is a “syntactic sugar” (syntax that is designed to make things easier to read, but doesn’t introduce anything new), because we could actually declare the same without class
keyword at all:
```js run // rewriting class User in pure functions
// 1. Create constructor function function User(name) { this.name = name; } // a function prototype has “constructor” property by default, // so we don’t need to create it
// 2. Add the method to prototype User.prototype.sayHi = function () { alert(this.name); };
// Usage: let user = new User(“John”); user.sayHi(); ```
The result of this definition is about the same. So, there are indeed reasons why class
can be considered a syntactic sugar to define a constructor together with its prototype methods.
Still, there are important differences.
First, a function created by class
is labelled by a special internal property [[FunctionKind]]:"classConstructor"
. So it’s not entirely the same as creating it manually.
The language checks for that property in a variety of places. For example, unlike a regular function, it must be called with new
:
```js run class User { constructor() {} }
alert(typeof User); // function User(); // Error: Class constructor User cannot be invoked without ‘new’ ```
Also, a string representation of a class constructor in most JavaScript engines starts with the “class…”
```js run class User { constructor() {} }
alert(User); // class User { … } ```
There are other differences, we’ll see them soon.
Class methods are non-enumerable. A class definition sets enumerable
flag to false
for all methods in the "prototype"
.
That’s good, because if we for..in
over an object, we usually don’t want its class methods.
Classes always use strict
. All code inside the class construct is automatically in strict mode.
Besides, class
syntax brings many other features that we’ll explore later.
Just like functions, classes can be defined inside another expression, passed around, returned, assigned, etc.
Here’s an example of a class expression:
Similar to Named Function Expressions, class expressions may have a name.
If a class expression has a name, it’s visible inside the class only:
```js run // “Named Class Expression” // (no such term in the spec, but that’s similar to Named Function Expression) let User = class !MyClass/! { sayHi() { alert(MyClass); // MyClass name is visible only inside the class } };
new User().sayHi(); // works, shows MyClass definition
alert(MyClass); // error, MyClass name isn’t visible outside of the class ```
We can even make classes dynamically “on-demand”, like this:
```js run function makeClass(phrase) { // declare a class and return it return class { sayHi() { alert(phrase); } }; }
// Create a new class let User = makeClass(“Hello”);
new User().sayHi(); // Hello ```
Just like literal objects, classes may include getters/setters, computed properties etc.
Here’s an example for user.name
implemented using get/set
:
```js run class User {
constructor(name) { // invokes the setter this.name = name; }
! get name() { /! return this._name; }
! set name(value) { /! if (value.length < 4) { alert(“Name is too short.”); return; } this._name = value; }
}
let user = new User(“John”); alert(user.name); // John
user = new User(""); // Name is too short. ```
Technically, such class declaration works by creating getters and setters in User.prototype
.
Here’s an example with a computed method name using brackets [...]
:
```js run class User {
! ‘say’ + ‘Hi’ { /! alert(“Hello”); }
}
new User().sayHi(); ```
Such features are easy to remember, as they resemble that of literal objects.
warn header="Old browsers may need a polyfill" Class fields are a recent addition to the language.
Previously, our classes only had methods.
“Class fields” is a syntax that allows to add any properties.
For instance, let’s add name
property to class User
:
```js run class User { ! name = “John”; /!
sayHi() { alert(Hello, ${this.name}!
); } }
new User().sayHi(); // Hello, John! ```
So, we just write “
The important difference of class fields is that they are set on individual objects, not User.prototype
:
```js run class User { ! name = “John”; /! }
let user = new User(); alert(user.name); // John alert(User.prototype.name); // undefined ```
We can also assign values using more complex expressions and function calls:
```js run class User { ! name = prompt(“Name, please?”, “John”); /! }
let user = new User(); alert(user.name); // John ```
As demonstrated in the chapter info:bind functions in JavaScript have a dynamic this
. It depends on the context of the call.
So if an object method is passed around and called in another context, this
won’t be a reference to its object any more.
For instance, this code will show undefined
:
```js run class Button { constructor(value) { this.value = value; }
click() { alert(this.value); } }
let button = new Button(“hello”);
! setTimeout(button.click, 1000); // undefined /! ```
The problem is called “losing this
”.
There are two approaches to fixing it, as discussed in the chapter info:bind:
setTimeout(() => button.click(), 1000)
.Class fields provide another, quite elegant syntax:
```js run class Button { constructor(value) { this.value = value; } ! click = () => { alert(this.value); } /! }
let button = new Button(“hello”);
setTimeout(button.click, 1000); // hello ```
The class field click = () => {...}
is created on a per-object basis, there’s a separate function for each Button
object, with this
inside it referencing that object. We can pass button.click
around anywhere, and the value of this
will always be correct.
That’s especially useful in browser environment, for event listeners.
The basic class syntax looks like this:
class MyClass {
prop = value; // property
constructor(...) { // constructor
// ...
}
method(...) {} // method
get something(...) {} // getter method
set something(...) {} // setter method
[Symbol.iterator]() {} // method with computed name (symbol here)
// ...
}
MyClass
is technically a function (the one that we provide as constructor
), while methods, getters and setters are written to MyClass.prototype
.
In the next chapters we’ll learn more about classes, including inheritance and other features.

John Legend named People magazine's 'sexiest man alive'
(Reuters) - Multi-talented singer and actor John Legend was named People magazine’s “sexiest man alive” on Tuesday, but said he wondered whether he could live up to the title.
Legend, 40, is married to model Chrissy Teigen with whom he has two children and is the first black man to have achieved coveted Emmy, Grammy, Oscar and Tony (EGOT) status for his work on stage and screen.
“I was excited, but I was a little scared at the same time because it’s a lot of pressure,” the entertainer told People magazine.
“Everyone’s going to be picking me apart to see if I’m
sexy enough to hold this title. I’m (also) following Idris Elba, which is not fair and is not nice to me!”
British actor Idris Elba took the title last year. Other actors and singers who have been given the title by the magazine’s editors in recent years include Blake Shelton, Chris Hemsworth, Adam Levine, George Clooney and Channing Tatum.
Legend, currently a coach on U.S. television talent series “The Voice,” won the first of 10 Grammys for his 2004 debut album “Get Lifted” and its hit ballad “Ordinary People.”
He took home an Oscar for the song “Glory” for the movie “Selma,” a Tony for co-producing the Broadway play “Jitney” and an Emmy for producing the 2018 television adaptation of “Jesus Christ Superstar” in which he played Jesus.
Legend appears on the front cover of the People magazine issue appearing on newsstands on Friday. people.com/sexiestmanalive2019

Model Index
A database index is a data structure that improves the speed of data retrieval operations on a database table at the cost of additional writes and storage space to maintain the index data structure. Indexes are used to quickly locate data without having to search every row in a database table every time a database table is accessed. Indexes can be created using one or more columns of a database table, providing the basis for both rapid random lookups and efficient access of ordered records.
An index is a copy of selected columns from a model, being a readonly property which returns a ColumnSort array, specified by a pair of DbIndexAttribute (at model class level) and _DbIndexAttribute (at property level):
[DbIndex(nameof(IX_Address_StateProvince), Description = "Nonclustered index.")]
public class Address : ...
{
...
[_DbIndex]
private ColumnSort[] IX_Address_StateProvince
{
get { return new ColumnSort[] { StateProvince }; }
}
...
}
Note
As its name suggests, DbIndex affects database server only. Unlike unique constraint, setting IsUnique property of DbIndexAttribute to true, will not enforce data row unique for dataset.
You can add index by clicking the left top drop down button of Model Visualizer tool window, then click 'Add Index...':
The following dialog will be displayed:
Fill the dialog form and click "OK", code of a DbIndex will be generated automatically.

Helper Functions
What are Helpers?
Helpers, as the name suggests, help you with tasks. Each helper file is simply a collection of functions in a particular category. There are URL Helpers, that assist in creating links, there are Form Helpers that help you create form elements, Text Helpers perform various text formatting routines, Cookie Helpers set and read cookies, File Helpers help you deal with files, etc.
Unlike most other systems in CodeIgniter, Helpers are not written in an Object Oriented format. They are simple, procedural functions. Each helper function performs one specific task, with no dependence on other functions.
CodeIgniter does not load Helper Files by default, so the first step in using a Helper is to load it. Once loaded, it becomes globally available in your controller and views.
Helpers are typically stored in your system/Helpers, or app/Helpers directory. CodeIgniter will look first in your app/Helpers directory. If the directory does not exist or the specified helper is not located there CI will instead look in your global system/Helpers directory.
Loading a Helper
Note
The URL helper is always loaded so you do not need to load it yourself.
Loading a helper file is quite simple using the following method:
<?php
helper('name');
Where name
is the file name of the helper, without the “.php” file
extension or the “_helper” part.
Important
CodeIgniter helper file names are all lowercase.
Therefore, helper('Name')
will not work on case-sensitive file systems
such as Linux.
For example, to load the Cookie Helper file, which is named cookie_helper.php, you would do this:
<?php
helper('cookie');
Note
The Helper loading method above does not return a value, so don’t try to assign it to a variable. Just use it as shown.
Loading Multiple Helpers
If you need to load more than one helper at a time, you can pass an array of file names in and all of them will be loaded:
<?php
helper(['cookie', 'date']);
Loading in a Controller
A helper can be loaded anywhere within your controller methods (or even within your View files, although that’s not a good practice), as long as you load it before you use it.
You can load your helpers in your controller constructor so that they become available automatically in any method, or you can load a helper in a specific method that needs it.
However if you want to load in your controller constructor, you can use the $helpers
property in Controller instead. See Controllers.
Loading from Non-standard Locations
Helpers can be loaded from directories outside of app/Helpers and system/Helpers, as long as that path can be found through a namespace that has been set up within the PSR-4 section of the Autoloader config file. You would prefix the name of the Helper with the namespace that it can be located in. Within that namespaced directory, the loader expects it to live within a sub-directory named Helpers. An example will help understand this.
For this example, assume that we have grouped together all of our Blog-related
code into its own namespace, Example\Blog
. The files exist on our server at
Modules/Blog/. So, we would put our Helper files for the blog module in
Modules/Blog/Helpers/. A blog_helper file would be at
Modules/Blog/Helpers/blog_helper.php. Within our controller we could
use the following command to load the helper for us:
<?php
helper('Example\Blog\blog');
You can also use the following way:
<?php
helper('Example\Blog\Helpers\blog');
Note
The functions within files loaded this way are not truly namespaced. The namespace is simply used as a convenient way to locate the files.
Auto-loading Helpers
New in version 4.3.0.
If you find that you need a particular helper globally throughout your application,
you can tell CodeIgniter to auto-load it during system initialization.
This is done by opening the app/Config/Autoload.php file
and adding the helper to the $helpers
property.
Using a Helper
Once you’ve loaded the Helper File containing the function you intend to use, you’ll call it the way you would a standard PHP function.
For example, to create a link using the anchor()
function in one of
your view files you would do this:
<div>
<?= anchor('blog/comments', 'Click Here') ?>
</div>
Where Click Here
is the name of the link, and blog/comments
is the
URI to the controller/method you wish to link to.
“Extending” Helpers
To “extend” Helpers, create a file in your app/Helpers/ folder with an identical name to the existing Helper.
If all you need to do is add some functionality to an existing helper - perhaps add a function or two, or change how a particular helper function operates - then it’s overkill to replace the entire helper with your version. In this case, it’s better to simply “extend” the Helper.
Note
The term “extend” is used loosely since Helper functions are procedural and discrete and cannot be extended in the traditional programmatic sense. Under the hood, this gives you the ability to add to, or to replace the functions a Helper provides.
For example, to extend the native Array Helper you’ll create a file named app/Helpers/array_helper.php, and add or override functions:
<?php
// any_in_array() is not in the Array Helper, so it defines a new function
function any_in_array($needle, $haystack)
{
$needle = is_array($needle) ? $needle : [$needle];
foreach ($needle as $item) {
if (in_array($item, $haystack, true)) {
return true;
}
}
return false;
}
// random_element() is included in Array Helper, so it overrides the native function
function random_element($array)
{
shuffle($array);
return array_pop($array);
}
Important
Do not specify the namespace App\Helpers
.
The helper()
function will scan through all PSR-4 namespaces defined in app/Config/Autoload.php
and load in ALL matching helpers of the same name. This allows any module’s helpers
to be loaded, as well as any helpers you’ve created specifically for this application. The load order
is as follows:
app/Helpers - Files loaded here are always loaded first.
{namespace}/Helpers - All namespaces are looped through in the order they are defined.
system/Helpers - The base file is loaded last
Now What?
In the Table of Contents, you’ll find a list of all the available Helpers. Browse each one to see what they do.

But I guess dyor is still in order so...
CryptoNinjaa05-Apr-19 11:55 AM
Experience is not free imo. You have to lose to learn. Or atleast thats my view on my past trading experiences
It is only D1 of trading so it could come back up once its bottomed. Maybe worth a punt below ieo if poss
Cryptoon05-Apr-19 11:58 AM
I feel bad for the guy in the chat claiming he had already mined 3-4BTC worth of that shit
eagerly waiting for more btc to arrive from exchanges because it had to go up today
etc etc

CryptoNinjaa05-Apr-19 12:07 PM
They got 2x so they can go down more for sure
PHBA206105-Apr-19 12:09 PM
probably people are afraid of being dumped on, because of that twitter video, fyi the vietnamese group in that video has managed to buy about $220000 worth of VBK

Veriblock's system of spamming the btc network with 512 times as many BTC transactions as Komodo needs is going to result in btc transactions costing $100 again, at which point Veriblock will die because its insanely expensive to use.
Alright05-Apr-19 01:49 PM
ZEN accomplishes basically the same thing without BTC being involved at all
forces forks to be mined publicly
PHBA206105-Apr-19 01:54 PM
Zencash right ?
Alright05-Apr-19 01:55 PM
yes
Although ZEN actually prevents attacking forks from reorging the network
from what I understand about VBK, it does not
Buddz199305-Apr-19 01:56 PM
so how are people buying into that sh**?
srsly it blows my mind.
Markus05-Apr-19 01:56 PM

hype of losing their money
PHBA206105-Apr-19 01:56 PM
because of the #IEO label ...
Buddz199305-Apr-19 01:57 PM
another bitconnect scheme
10% makes money the other 90% get rkted.
PHBA206105-Apr-19 01:57 PM
it's still too soon to jump into conclusion
Buddz199305-Apr-19 01:57 PM
well from the looks off it
it shows that its not adding any value to the ecosystem.
its basically replicating what others have done but in a more expensive way
PHBA206105-Apr-19 01:58 PM
people get rekt because of their greediness, it's not necessary Veriblock's fault


Ooohh.. Food is definitely the first! The food of the gods are definitely heavenly!
There's nothing fancier than living like a god. Even physically we also would love to.
Santorini is essentially what remains after an enormous volcanic eruption that destroyed the earliest settlements on a formerly single island, and created the current geological caldera. A giant central, rectangular lagoon, which measures about 12 by 7 km (7.5 by 4.3 mi), is surrounded by 300 m (980 ft) high, steep cliffs on three sides.[4] The main island slopes downward to the Aegean Sea. On the fourth side, the lagoon is separated from the sea by another much smaller island called Therasia; the lagoon is connected to the sea in two places, in the northwest and southwest. The depth of the caldera, at 400m, makes it impossible for any but the largest ships to anchor anywhere in the protected bay; there is also a fisherman's harbour at Vlychada, on the southwestern coast. The island's principal port is Athinios. The capital, Fira, clings to the top of the cliff looking down on the lagoon. The volcanic rocks present from the prior eruptions feature olivine, and have a small presence of hornblende.
