Tesla Model 3 Owners Ditch Toyota Prius And BMW 3 Series But Conflicting Results In Brand Survey
by Brooke CrothersThe Tesla Model 3 fared well in surveys this past week, though one showed conflicting results.
A Bloomberg survey showed U.S. car buyers are not only trading in upscale sedans like the BMW 3 Series for the Model 3 but also decidedly less-luxurious brands like the Toyota Prius, Honda Civic, and Honda Accord.
Here are the highlights of Bloomberg’s “Top 10 Cars Given Up for a Tesla Model 3”*
- No. 1 was Toyota Prius, with an average selling price of $27,080
- No. 2, the BMW 3 Series, with an average selling price of $46,477
- No. 5, the Nissan Leaf with an average selling price of $34,562
- Others ranked in the top ten were inexpensive cars like the Toyota Camry, Honda Accord, Honda Civic, and Mazda 3
“I’m not rich, I’m an ordinary man with an ordinary job,” Bloomberg quoted one Tesla Model 3 buyer as saying. Which demonstrates that the Model 3 is winning over less-affluent Americans too.
BMW the biggest loser
While Toyota was the hardest hit in raw customer conversions to the Model 3, the lost sales don’t impact the Japanese automaker as much (compared to BMW) since it sells so many cars in the U.S., according to Bloomberg.
BMW, however, has the “most to lose—almost five times more vulnerable than Mercedes-Benz,” said Bloomberg, adding that “Mercedes is built for comfort and class, while BMW is defined by its driving performance.”
Another EV survey showed Tesla ranked both higher and lower than Toyota
“Tesla is the leader when it comes to brand perception,” according to a survey by CarGurus released this past week.
Tesla was ranked at the top with 33% of all respondents saying that it is the company most trusted to develop EVs. Toyota was second with 14%, Honda 8%, General Motors 7%, and Ford 6%.
However, Tesla was ranked lower than Toyota in another survey question, the “most popular brands among shoppers that are likely to purchase an EV in the next six months.” Here, the Japanese carmaker was ranked No. 1, at 54%, and Tesla second, at 52%.
This is surprising because Toyota is, in fact, not a leader in pure electric vehicle sales in the U.S. The most popular Toyota electric vehicle in the U.S. is the Prius Prime. But that is a plug-in hybrid with a gas engine and gets only about 25 miles of battery range. The Prime mustered sales of only 1,650 vehicles in the U.S. in September, far behind the Model 3’s sales number of 19,100.
It could be that respondents are conflating the Toyota Prius hybrid – a longtime favorite with green car buyers – with an EV.
I queried CarGurus about this (they have yet to respond).

*The Model 3 had an average price of $50,528

5) Rolling your own data query protocol
Case Study: Online Cloud Storage Company
The standard solution to this problem is to use a strong form of SSL. However, <company> chose an interesting approach to SSL. Instead of serving the entire site from a single secure server or group of servers using strong SSL, they came up with a clever scheme to allow them to serve most of their site insecurely. <company>’s main index.html is hosted on a secure server using SSL with 2048-bit RSA. However, everything else is loaded dynamically from JavaScript code in index.html, and hash checked. . . .
. . .you would have to trust the entire CDN network and also trust that nobody has broken 1024-bit SSL yet (which is known to be weak by modern standards). In order to solve this problem, <company> hashes all of the additional content, and stores the hashes in index.html. This creates a chain of trust, or as they put it, “secure boot for websites”. Clever.
function h(s)
{
var a = [0,0,0,0];
var aes = new sjcl.cipher.aes([111111,222222,333333,444444]);
s += Array(16).join('X');
for (var i = s.length & -16; i--; )
{
a[(i>>2)&3] ^= s.charCodeAt(i)<<((7-i&3)<<3);
if (!(i&15)) a = aes.encrypt(a);
}
return a;
}
So what's wrong here?

4) Rolling your own secure version of HTTP
Case Study: Amazon
AWS signature version 1 signs an HTTP query string as follows:
Split the query string based on '&' and '=' characters into a series of key-value pairs.
Sort the pairs based on the keys.
Append the keys and values together, in order, to construct one big string (key1 + value1 + key2 + value2 + ... ).
Sign that string using HMAC-SHA1 and your secret access key.

What's worse that rolling your own secure version of HTTP?
3) Not using HTTPS at all
3) Not using HTTPS at all
Even with a perfectly secure algorithm, you're still vulnerable to replay attacks.
Because there are no delimiters between the keys and values, the signature for "foo=bar" is identical to the signature for "foob=ar";
moreover, the signature for "foo=bar&fooble=baz" is the same as the signature for "foo=barfooblebaz".


In the GServ Config you can define filters. GServ defines 2 kinds of filters: After and Before
As you can probably guess, before-filters are called before the Route code is called.
Similarly, after-filters are called after the Route code is called and has a chance to modify the output
produced by the Route.
| Argument | Type | Description | ||||||
|---|---|---|---|---|---|---|---|---|
| name | String | Optional name of the filter. | ||||||
| url | String | The path for which this filter is defined. | ||||||
| method | List<String> | "GET" | "PUT" | "POST" | "DELETE" | ||||||
| options | Map |
|
||||||
| order | Integer | An integer which specifies the relative order of filter execution. Low numbers are run first. The default is 5. | ||||||
| filterBehaviorClosure | Closure | The closure that is called whenever this filter is invoked.
The arguments passed to the closure vary depending on the filter's options. If the 'PassRouteParams'is set
to 'true', then the route variables will be passed to the closure, in order, as arguments..
This closure must return: the current HttpExchange, a modified or wrapped HttpExchange implementation, or null. |
The before-filter may choose to:
| Argument | Type | Description | ||||||
|---|---|---|---|---|---|---|---|---|
| name | String | Optional name of the filter. | ||||||
| url | String | The path for which this filter is defined. | ||||||
| method | List | "GET" | "PUT" | "POST" | "DELETE" | ||||||
| options | Map |
|
||||||
| order | Integer | An integer which specifies the relative order of filter execution. Lowest numbers are run first. The default is 5. | ||||||
| filterBehaviorClosure | Closure | The closure that is called whenever this filter is invoked. Returns null if no change to the data is needed else returns the modified data |
The after-filter may choose to:
HttpExchange beforeFn ( )
byte[] afterFn ( HttpExchange exchange, byte[] data )
Server Config may include Filter definitions. There are 3 builtin functions:
// Add a filter to intercept and reject letters to 'Lee' before("rejectLee", "/letter/:name", "GET", [(FilterOptions.PassRouteParams): true] ) { name -> if ( name == "Lee") error(403, "Lee not allowed"); else nextFilter(); return exchange; }
// Add a filter to capture the response and change its text to uppercase after("upperCaseFilter", "/letter/:name", "GET", [:] ) { exchange, data -> def newData = new String(data).toUpperCase().bytes; return newData; }

Chapter 11
Superclasses and Subclasses
Inheritance is a very important feature of object-oriented programming, a mechanism which allows one class to inherit the behaviors and attributes from another class. Inheritance allows you to create a hierarchy of classes. Thus, it has a direct impact on the design of your programs.
To represent a hierarchy, you can create a class that defines characteristics common to a group of objects. Using inheritance, this class can then be inherited by other classes which are more specific.
In this chapter, we will learn about inheritance, its mechanisms, and applications. We will see how to extend superclasses, the behavior of constructors in class hierarchies, their invocation, and much more.
+++ title = “Understanding Inheritance” weight = 1 +++
Inheritance is a concept of object-oriented programming. You can derive a class from another class with inheritance.
A class that you inherit is known as parent class, or base class, or superclass.
A class which inherits is known as child class, or derived class, or subclass.
Imagine you have a class that already has behavior and attributes that another class needs. You do not have to rewrite or copy your code to have the same behavior and attributes. With inheritance, your class automatically receives the behavior and attributes from its superclass. Basically, a class becomes a combination of its own features and all the features it inherits from the classes above it in the hierarchy.
To inherit a class, you simply specify the class to inherit in the definition of your class using the extends clause. The general form of the extends clause is shown here.
class A extends B
...
Here, A
represents the name of your class. B
represents the name of the
you want to inherit. In other words, A
represents the name of the subclass
and B
represents the name of the superclass.
A class can have one or more superclasses. This type of inheritance is called multiple inheritance because each class can have one or more superclasses.
In other object-oriented programming languages such as Zen, classes can have only one superclass. This is called single inheritance. Zen makes inheritance simpler by allowing only single inheritance.
With inheritance, you can implement is-a-type-of relationships. Here are some examples. * Cricket is a type of game. * A tiger is a type of animal. * A duck is a type of bird. * A mango is a type of fruit.
Here is an example that demonstrates the hierarchy of shapes.
// ShapeExample.zen
class Shape
@Property
var area
@Property
var perimeter
class Square extends Shape
@Property
var side
class Rectangle extends Shape
@Property
var length
@Property
var breadth
class Circle extends Shape
var radius
function main(...arguments)
var square = new Square()
square.setArea(100)
square.setPerimeter(40)
square.setSide(10)
print(serialize(square, 'json'))
var rectangle = new Rectangle()
rectangle.setArea(70)
rectangle.setPerimeter(34)
rectangle.setLength(7)
rectangle.setBreadth(10)
print(serialize(rectangle, 'json'))
Circle circle = new Circle()
circle.setArea(314.28)
circle.setPerimeter(62.85)
circle.setRadius(10)
print(serialize(circle, 'json'))
In this example, we demonstrate an hierarchy of shapes. Consider three shapes: squares, rectangles, and circles.
To represent shapes, you can create a class named Shape
. It describes features
common to all shapes, such as area and perimeter. Being the good citizens of
the Zen world, you make these fields private and thanks to the @Property
annotation
Zen creates accessors to expose them consistently.
We know that a square is a type of shape. Obviously, it has properties such
as area and perimeter. Instead of rewriting the accessors and fields to implement
these properties, you simply inherit the Shape
class. Of course, Square
has
side
, which describes the length of its sides. Thus, we extend the features of
Shape
by adding the field and accessors for side
.
Similarly, a rectangle is a type of shape. It extends the Shape
class to inherit
the area
and perimeter
attributes and their corresponding accessors.
A rectangle has four sides, with equal opposite sides known as length and breadth.
Therefore, we extend the features of Shape
by adding these two fields and their
corresponding accessors.
In the main()
function, we create an instance of Square
, Rectangle
, and
Circle
. Although, we did not create accessors for area and perimeter
in these classes, we are still able to invoke their accessors because these
methods were inherited by them.
The Square
, Rectangle
, and Circle
classes have is-a-type-of relationship
with the Shape
class because they are all a type of shape.
You know that private fields are accessible only within the class they are declared. Which means, when you inherit a class with private fields, you will not be able to access them. In other words, private fields are not inherited by classes. When you create an instance of the subclass, the instance is a combination of the subclass and all the superclasses. Which goes to say the instance gets its own copy of all the fields, including private fields declared throughout the hierarchy. But they are only accessible by the classes in which they were declared.
In order to access a field declared in a superclass from a subclass, the field must be either declared as public or secret. If you declare the field as public, any class can access it. If you want to limit the visibility of the field only to your class hierarchy, declare it as secret. You must remember that secret fields are accessible by other classes in the same package even if they are not a part of your hierarchy.
You can inherit a class that inherits another class. Thus, inheritance forms an hierarchy. Here is an example.
class Vehicle
@Property
var license
@Property
var make
@Property
var model
class Car extends Vehicle
@Property
var seats
@Property
var wheels
@Property
var passengers
class Sedan extends Car
...
class Hatchback extends Car
...
+++ title = “The Object Class” weight = 2 +++
Inheritance is comparable to how you inherited traits such as your height, eyes, hair, DNA, and allergies from your parents. They in turn inherited some of their traits from their parents, that is, your grandparents. Inheritance of such tratis basically keeps going backwards in time till the very first people who populated Earth, say Adam and Eve, the root of your ancestorial hierarchy.
Similarly, every class hierarchy has a root class. All the class hierarchies in
Zen have the same class as their root class: the Object
class. When the extends
clause is absent, an implicit extends clause inheriting the Object
class is
provided by Zen.
In Zen, the Object
class is the root of class hierarchy. In other words,
the Object
class is the superclass of all classes in Zen.
The Object
class is special because it is the only class in Zen that does not
inherit any other class.
The Object
class defines the following functions, which means that they are
available in every object.
-
The
clone()
function creates a clone of the object is being invoked against. -
The
equals()
function determines whether one object is equal to another object. It compares two objects and returnstrue
if both are same, otherwise it returnsfalse
. -
The
finalize()
function is invoked by the Zen Virtual Machine (ZVM) before the object is destroyed. -
The
getClass()
returns an object which represents the class of an object at runtime. This function is part of the reflection API, which allows you to dynamically load classes, create instances, and invoke functions. It is a final function and cannot be overridden. -
The
hash()
function returns the hash code of the object. -
You have already seen the
toString()
function. It returns a string that describes the object.+++ title = “Overriding Functions” weight = 3 +++
A subclass inherits all the behavior and attributes of its superclass. It can then extend the behavior and attributes of its superclass. In fact, a subclass can change the behavior provided by its superclass. This is known as overriding. Overriding functions is a feature of polymorphism. In this section, you will learn about overriding functions.
When you call an instance function, Zen looks for the definition of the function
in the object’s class. If it does not find it, Zen looks up for the function
in its superclasses, all the way to the Object
class, until the function definition
is found. If the definition is not found, the function is considered as non-existent
and the virtual machine throws an exception. You will learn more about exceptions
in the upcoming chapters.
Inheritance allows you to define functions in superclasses and use them in instances of your subclasses. This helps you avoid rewriting the code in your subclasses. However, sometimes you may want to invoke a function but change its behavior which was defined in a superclass. In such cases, you can alter it. This is known as function overriding.
To override a function in a subclass you simply need to define the function in your subclass with the same signature and return type. Zen determines if a function is overridden by comparing the signature of your function in the subclass and the superclass. If the signatures match, then that function is considered as overridden. When you invoke that function, the overridden version is executed instead of the one in the superclass.
Consider the following example which prints the popular lines of the characters from Friends.
// Friends.zen
class Friend
function getPopularLine()
return 'F.R.I.E.N.D.S is the best show ever, isn\'t it?!'
class JoeyTribbiani extends Friend
@Override
function getPopularLine()
return 'How you doin\'?'
class ChandlerBing extends Friend
@Override
function getPopularLine() {
// PS: Could Chandler be more funny?
// This is the only program I have ever written laughing.
return 'Until I was 25, I thought that the only response to "I love you" was "Oh crap!"'
class PhoebeBuffay extends Friend
@Override
function getPopularLine()
// That's it. I'm off to watch Friends.
return 'They don\'t know that we know they know we know.'
function main(...arguments)
var joey = new JoeyTribbiani()
print('Joey: ' + joey.getPopularLine())
var chandler = new ChandlerBing()
print('Chandler: ' + chandler.getPopularLine())
var phoebe = new PhoebeBuffay()
print('Phoebe: ' + phoebe.getPopularLine())
When you compile this example, the compiler produces fives files, one for each class. The output of the program is shown here.
Joey: How you doin'?
Chandler: Until I was 25, I thought that the only response to "I love you" was "Oh crap!"
Phoebe: They don't know that we know they know we know.
The Friend
class defines a function called getPopularLine()
. It always
returns the string 'F.R.I.E.N.D.S is the best show ever, isn\'t it?!'
.
To demonstrate function overriding, we created three other classes called
JoeyTribbiani
, ChandlerBing
and PheobeBuffay
which inherit the Friend
class. Each of these classes define the getPopularLine()
function with the same
signature. Thus, they override the getPopularLine()
function in their respective
classes.
Sometimes you may misspell a function name or change the signature by accident in your subclass. Since Zen does not force your subclass to override the definition of a function, you may end up creating a new function instead of overriding a function that exists in your superclass.
You always need to make sure that you have correctly overridden a function. Zen
provides an annotation called Override
. With this annotation you can tell the
compiler to check if you have correctly overridden a function.
An annotation is a special class that provides supplemental information
about your source code. They are similar to comments, except they are not ignored
by the compiler. Annotations start with @
. They provide information about your
source code to tools such compilers. You will learn more about annotations in the
upcoming chapters.
In the main()
function we create an instance of each of the subclasses of Friend
.
We assign the instances to their respective variables.
You can prevent a subclass from overriding a function. You simply need to add
the final
keyword in the function declaration. When a subclass tries to override
a final function, the compiler generates errors.
Here is an example of a final function.
final function printStatistics()
...
Zen provides a special operator called as is
operator. It allows you
to determine whether an object is an instance of the specified class.
Here is the general form the instance of operator.
object.class is Class
Here, the object
represents the object you want to test. The is
operator
is a keyword. The Class
represents the class the object should
be an instance of.
Here is an example.
if friend.class is ChandlerBing
print('It is Chandler!')
else
print('I don\'t know who this is. Is it Monica?')
+++ title = “Working with Constructors and Inheritance” weight = 4 +++
When you inherit a class, the constructors are not inherited because cnostructors are not instance members. Which means each class should create its own constructors. However, sometimes you may want to invoke the constructor of a superclass from your subclass.
For example, to initialize the fields in a superclass you either need access to them or invoke the constructor. The former technique is verbose and not recommended because it violates the principles of encapsulation. Instead you can invoke the superclass constructor.
Invoking Superclass Constructors
A constructor can call the superclass constructor from a subclass. Zen provides
special syntax for this purpose. You must use the super
keyword with parenthesis.
This is useful when your subclass constructor requires some behavior which already
exists in superclass constructor. Whenever you want invoke a supeclass constructor
you can use the super keyword.
Here is the general form invoke a superclass constructor.
Class.super(arguments)
Here, the Class indicates the superclass whose constructor you want to invoke. It is optional if your class inherits only one superclass. The arguments are the values you want to pass to your superclass constructor.
You need to follow these rules when calling a superclass constructor.
You can call a superclass constructor only in the first statement. But in the above example, a declaration statement is the first statement. This results in a compile-time error.
RULE 1 - A constructor can call one or more superclass constructor.
For example, this will compile.
function new(title)
UACertifiedMovie.super(null)
Movie.super(title, 0.0, 0.0)
}
You can call one or more superclass constructor. However, you can invoke only one constructor per superclass. Otherwise, the compiler generates error.
RULE 2 - You can call superclass constructors only if their invocations occur before any other statement.
For example, this will not compile.
function new(title)
var i = 0
super(title, 0.0, 0.0)
RULE 3 - You can either invoke another constructor or a superclass constructor, not both.
For example, the first constructor can call the second constructor. The second constructor can call the third constructor.
function new(title)
super(title, 0.0, 0.0)
this('Christopher Nolan')
You can call a superclass constructor or another constructor in your class. But the constructor show above invokes both the constructors. This results in a compile-time error.
This rule applies only when you explicitly invoke a superclass constructor. Because when you do not invoke the superclass constructor, Zen automatically invokes the default superclass constructor.
+++ title = “Understanding the Extended Self Reference” weight = 5 +++
You have already seen how the this
reference works. It provides a reference to
the current instance. You can use it distinguish between a local variable and an
instance variable with the same name.
Sometimes you may want to distinguish between a subclass instance member and
a superclass instance member. In such cases, you can use the extended form of the
this
keyword known as the extended self reference. You can reference a superclass
directly above the current subclass in the hierarchy.
A very common place where the extended form of the this
keyword is used is
when you override a function and you want to invoke the function defined in the
superclass.
Here is an example, where the superclass reference is used.
class A
function printMessage()
print('This is the function defined in the superclass.')
class B extends A
@Override
function printMessage()
A.this.printMessage()
print('This is the function defined the subclass.')
In Zen, you cannot shadow fields, that is, a subclass cannot declare a public field with the same signature as another public field that is already present in a superclass. This design choice was made because it shadowing fields makes your code less readable. Although this does not matter, if the fields are private in the first place, because private fields are not inherited.
The compiler generates errors if you try to compile the following example.
class A
public var message = 'This is the superclass message.'
class B extends A
public var message = 'This is the subclass message.'

Involves complex numbers z = x + iy such that z*z + c
does not diverge when iterated from z = 0
where c = Xp + iYp, where Xp and Yp are the scaled values for of x and y for the pixel
Implemented using an escape time algorithm
Iterate Z*Z + c until it is greater than 4 or the number of iterations is greater than escape value
The following algorithm is used
For each pixel (Px, Py) on the screen, do: { x0 = scaled x coordinate of pixel -2.5 <= x < = 1 y0 = scaled y coordinate of pixel -1 <= y < = 1 x = 0.0 y = 0.0 iteration = 0 max_iteration = 1000 while (x*x + y*y < 2*2 AND iteration < max_iteration) { xtemp = x*x - y*y + x0 y = 2*x*y + y0 x = xtemp iteration = iteration + 1 } color[Px, Py] = iteration < max_iteration ? white : black }
Approaches that can be taken
Process per pixel
Process per line
Consider the space required
-2.5 <= x <= 1.0
-1.0 <= y <= 1.0
Yields 200 by 350 pixels, 70000 processes
200 lines each of 350 pixels, 200 processes
Processing time is determined by the number of iterations
Visualisation
GPP Library provides a simple process based Canvas environment to display such images
It is itself a parallel of Manager and Interface processes but the user is not concerned with this detail
Visualisation influences performance
Two versions are provided, with and without visualisation. The versions are identical apart from the Collect process

There are plenty of books, videos, and online resources for developing iOS apps. Despite the fact that iPhone and iPad apps require a Mac for code development, there is little information about actually creating native Mac applications. The articles provided below demonstrate various aspects of Mac app development using the latest versions of Swift and SwiftUI. Hopefully these examples will provide a useful resource for Mac developers.
See the swift-macos repository on GitHub for example code.

New York alone reports its largest single-day jump in death toll. Many states have instituted a Stay a Home Order, which closes all non-essential businesses and establishments. Residents are only to leave their homes for groceries, walks, bike rides, and other small essential tasks. Forty three out of fifty states have instituted some sort of stay at home order. Here are the seven who haven’t:

I am a graduate of the Biomedical Engineering program at Rutgers University, New Brunswick, NJ. During my studies I learned the many facets of the industry including, but not limited to, biomechanics, bioelectric systems, and tissue engineering.
As a senior, I applied my knowledge in designing an Infrascope device that detects inaudible frequencies by shifting them into the range of human hearing. With this design it is possible to detect subtle vibrations in the human pulse, an early warning sign of carotid artery disease.

GSoC 2018 - Week 3 - Continuing with transolve
02 Jun 2018I continued my work of week 2 in this week as well. Though I was travelling for 2-3 days, I was able to give most of the hours to the work dedicated for this week. I had to add a detailed descriptive documentation for transolve
, for this I read documentation of the ode
module as Amit and Harsh suggested, apart from this I read several other documentation of sympy modules.
As of now transolve supports solving majority of exponential equations.
I have also imported exponential tests of solve and added a few of mine. Some of them needs another look, I have added them to XFAIL
as of now. I am working on these tests to pass. Also done minor changes in the function, like removed force=True
option from expand_log
because using this option is not a healthy choice as the function expands logarithm without considering the assumptions (for exponents the variable should be real) which may sometime get a wrong result.
Idea behind transolve
The idea is simple, we are mainly focusing on making it modular and extensible. So to achieve this different identifying and solving helpers will be implemented that will identify the type of equation and then solve it. For detailed information refer to the PR
Idea behind exponential solver
Exponential equations are solved by using logarithms. Currently the expo_solver
reduces the equation to log form which can further be handled by solveset itself. For this purpose expand_log function of sympy is used which reduces the equation using log identities.
Take for example a simple exponential equation 3**(2*x) - 2**(x + 3)
, this equation can be reduced to 2*x*log(3) - (x+3)*log(2)
, this type of equation is easily solvable by solveset
.
Once we approve on the documentation and the working of exponential solver I will proceed to implement logarithmic solver (probably in the coming week).
Hope things go as planned!!

To limit a search to a single repository, select a repository from the drop down list. If your search returns no results, try searching all the finding aids (the default search).
The results list will be displayed with the most relevant finding aids first. Search results are sorted by a relevance algorithm that weighs factors such as the number of search terms found in the full text of the finding aids and the number of terms found in certain fields.
Keyword searching: Enter one or more search terms in the search boxes
Browsing Library of Congress Subject headings
Choose a subject heading from the list under the heading "Selected Search Terms" by clicking on the hyperlinked heading. This will return a list of other relevant finding aids containing that subject heading.
**Note that this search does not search collection creators. For instance, clicking on the subject heading for Ted Hughes returns collections of other individuals with material related to Hughes. The search would not return finding aids for collections Ted Hughes created.


rstoolbox
is open source and, thus, contributions are more than welcomed.
If you feel there is a feature that might improve the library here are the steps you need do:
Add a new issue commenting on the feature. Try to explain exactly what you expect the library to do. Examples and example data always help. Features that are most welcomed are:
If nobody offers and you feel confident enough to do it, take the initiative and fork the repo into your own github user.
Ideally, you’ll want to work on a virtual environment; once you have one set up, you can clone your repo into your machine:
git clone https://github.com/YOUR-USERNAME/RosettaSilentToolbox
Start coding, committing and pushing your code. Make sure to add the appropriate Tests and Documentation to your new code.
Whenever you thing your code is working, create a pull request over the original repo. This will trigger the continuous integration test to run and assess your contribution.
When the tests are positive and a reviewer has accepted your pull request, merge the data to the master branch. We do thank you for your time and your improvements to the code.
Tests reside in rstoolbox/tests
and depend on pytest.
Development libraries required for tests and documentation building can be found in rstoolbox/ci/requirements_devel.txt
.
When running the test, the regular libraries will not be loaded from the default REQUIMENTS
file, but from the extra
rstoolbox/ci/requirements_test.txt
. The difference between both files being that, while REQUIMENTS
requests the
minimum working version for a given library, rstoolbox/ci/requirements_test.txt
requires the specified version of the test.
This is important for the test to succeed, specially for graphical libraries such as seaborn,
that might change their visuals from one version to another.
Note
This double library requirements entails the need to take rstoolbox/ci/requirements_test.txt
into account when adding a new feature
that needs the last version of an already required library to work.
The easiest way to execute them is through tox; for which three different environments are set up:
tox -e py27
tox -e py35
tox -e py36
As tox
works with virtual environments, this might produce some unexpected behaviours in MacOS due to the behaviour of matplotlib
.
See the known issues of the getting started section to see how to fix that.
New data to read can be added to the rstoolbox/tests/data
folder, but try to be sparse with it and add it only when necessary.
Be aware that the continuous integration will pass its tests if there is not a minimum of the new added code covered by new tests.
Documentation resides in sphinx-docs
and depends on sphinx. A full list of requirements for the
tests can be found in rstoolbox/ci/requirements_devel.txt
.
Any new function has to be properly documented in terms of function, inputs and outputs. Ideally, example code can be added to help comprehend the effects of the function. Use other functions as guidelines on how to generate documentation.
Be aware that functions are not automatically listed in their appropriate place in the docs, they need to be manually added to the API or corresponding object file.
Once the documentation is done, get into sphinx-docs
and run:
make clean
make html
to obtain your docs. You can check them locally opening a server with:
python -m SimpleHTTPServer
Lastly, list your new improvements into: sphinx-docs/releases/Vxxx.txt
where xxx
represents the higher version listed.
