Puts the logical processor in VMX operation with no current VMCS, blocks INIT signals, disables A20M, and clears any address-range monitoring established by the MONITOR instruction.10
The operand of this instruction is a 4KB-aligned physical address (the VMXON pointer) that references the VMXON region, which the logical processor may use to support VMX operation. This operand is always 64 bits and is always in memory.
IF (register operand) or (CR0.PE = 0) or (CR4.VMXE = 0) or (RFLAGS.VM = 1) or (IA32_EFER.LMA = 1 and CS.L = 0) THEN #UD; ELSIF not in VMX operation THEN IF (CPL > 0) or (in A20M mode) or (the values of CR0 and CR4 are not supported in VMX operation; see Section 23.8) or (bit 0 (lock bit) of IA32_FEATURE_CONTROL MSR is clear) or (in SMX operation11 and bit 1 of IA32_FEATURE_CONTROL MSR is clear) or (outside SMX operation and bit 2 of IA32_FEATURE_CONTROL MSR is clear) THEN #GP(0); ELSE addr ← contents of 64-bit in-memory source operand; IF addr is not 4KB-aligned or addr sets any bits beyond the physical-address width12 THEN VMfailInvalid; ELSE rev ← 32 bits located at physical address addr; IF rev[30:0] ≠ VMCS revision identifier supported by processor OR rev[31] = 1 THEN VMfailInvalid; ELSE current-VMCS pointer ← FFFFFFFF_FFFFFFFFH; enter VMX operation; block INIT signals; block and disable A20M;

11. A logical processor is in SMX operation if GETSEC[SEXIT] has not been executed since the last execution of GETSEC[SENTER]. A logical processor is outside SMX operation if GETSEC[SENTER] has not been executed or if GETSEC[SEXIT] was executed after the last execution of GETSEC[SENTER]. See Chapter 6, “Safer Mode Extensions Reference.”
12. If IA32_VMX_BASIC[48] is read as 1, VMfailInvalid occurs if addr sets any bits in the range 63:32; see Appendix A.1.

A Basic Pyxley App¶
Here we will go through building a basic web-application using Pyxley and Flask.
I recommend visiting the Real Python blog for a great intro to a basic app.
App
| package.json
| .bowerrc
| bower.json
|
└---project
| app.py
| templates
|
└---static
| css
| js
Some notes about the above structure
- This assumes that you are running the app from the
project
folder. - Any JavaScript created by the app should go in the
js
folder.
JavaScript!¶
Node & NPM¶
At the highest level, Node is our biggest JavaScript dependency. PyReact needs a JavaScript runtime and Node fills that role. In addition, we can use NPM to install Bower. This document won’t show you how to get Node or NPM, but for Mac OS X users, you can get it through homebrew.
Once you have NPM, simply type
npm install -g bower
This will give bower global access so that you can execute it.
Bower¶
Bower is a great package manager. In the examples
directory, each of the examples has a bower.json
file. This file
contains all the necessary packages for the app to run. Install the
packages by typing bower install
in the directory of the bower.json
file. There is a file called .bowerrc
that specifies the location that
bower will store the libraries.
If the .bowerrc
file looks like
{
"directory": "./project/static/bower_components"
}
Then the folder structure in static should look like the figure below after installation.
└---static
| css
| js
| bower_components
HTML & CSS¶
HTML templates used by flask are stored in the templates
folder. For our purposes,
we only need a really basic template that has a single div
element.

Everything in our app will be tied to this single component.
CSS¶
We store any additional CSS we need in the static\CSS
folder.
Flask¶
Courtesy of the Flask website, “Hello, World!” in Flask looks like the code below.
from flask import Flask
app = Flask(__name__)
@app.route('/')
def hello_world():
return 'Hello World!'
if __name__ == '__main__':
app.run()
We simply need to build upon this.
Adding Some Pyxley¶
Let’s start by importing some simple things and building upon the example above. We
will import some pyxley
components, create a UI, and load a data frame.
# Import flask and pandas
from flask import Flask, render_template
import pandas as pd
# Import pyxley stuff
from pyxley import UILayout
from pyxley.filters import SelectButton
from pyxley.charts.mg import LineChart, Figure
# Read in the data and stack it, so that we can filter on columns
df = pd.read_csv("fitbit_data.csv")
sf = df.set_index("Date").stack().reset_index()
sf = sf.rename(columns={"level_1": "Data", 0: "value"})
# Make a UI
ui = UILayout(
"FilterChart",
"./static/bower_components/pyxley/build/pyxley.js",
"component_id")
# Create the flask app
app = Flask(__name__)
At this point we now have some data and a layout to build upon. Adding the code below will add a dropdown select button and a line plot.
# Make a Button
cols = [c for c in df.columns if c != "Date"]
btn = SelectButton("Data", cols, "Data", "Steps")
# Make a FilterFrame and add the button to the UI
ui.add_filter(btn)
# Make a Figure, add some settings, make a line plot
fig = Figure("/mgchart/", "mychart")
fig.graphics.transition_on_update(True)
fig.graphics.animate_on_load()
fig.layout.set_size(width=450, height=200)
fig.layout.set_margin(left=40, right=40)
lc = LineChart(sf, fig, "Date", ["value"], init_params={"Data": "Steps"}, timeseries=True)
ui.add_chart(lc)
Finally, we need to transform all of the inputs into javascript and render the HTML template.
This assumes that the index.html
template has all of the javascript and css files specified
in the HTML.
sb = ui.render_layout(app, "./static/layout.js")
@app.route('/', methods=["GET"])
def index():
return render_template('index.html')
if __name__ == '__main__':
app.run()
Now when you run app.py
from the project
folder, accessing your localhost on port 5000 will lead to a simple plot. This example was adapted from the metricsgraphics example in the Pyxley repository.

Over the summer, I attended the Balfour Leadership Training Workshop at Ball State University (the Alma mater of David Letterman, who is a Sigma Chi) in Muncie, Indiana. It is a yearly conference held by Sigma Chi that hosts some hundred chapters, several thousand brothers, and boasts a number of workshops and networking opportunities. While there, I looked back on my days as a starry-eyed freshman who couldn't wait to go to his first "frat party," and wondered, "How did I get here?" If being in a fraternity - and going Greek in general - is about so much more than I thought, why did I even rush the first place, and more importantly, why did I stay?
As a freshman, I was unsure of whether or not I wanted to join a fraternity. I certainly wanted to make friends and have fun, but I had also heard the horror stories. Still, I decided "Why not?" And as I found out when I eventually pledged as a sophomore, pledging was anything but the terrible experience it had been made out to be. I also found the friends I had made were more than friends; they were brothers, tied to me for the rest of my life. So that's why I initially joined: friends, fun, and a promise I wouldn't be elephant-walking in a dark basement any time soon.
But then, come my junior year, I found myself on the other side of the process. I found people asking me why they should give Greek Life a chance, especially if they only thought fraternities and sororities stood for partying with friends, based on movies like Neighbors. But fraternities and sororities are not stereotypes, nor are the people in them. Some people aspire to be John "Bluto" Blutarsky, others don't even know what an "animal house" is, and often times, both are in the same fraternity. Contrary to popular belief, fraternities and sororities, on the whole, are about teaching you how to be upstanding men and women in society: courteous, intelligent, and above all else, leaders. Because fraternities and sororities are, at their heart, character-building institutions, and that is why I stayed.
At the end of the day though, joining a fraternity or sorority, whichever one you might choose, is a decision you have to make for yourself. I can assure you that there is more to Greek Life than meets the eye, but ultimately, my best advice is to go out to rush and learn what Greek Life is all about for yourself. If you find it's not for you, no harm done, and we won't hold it against you if you leave. But you'll never truly know unless you give it the old college try.

LIFE AND TIMES OF HANK GREENBERG, THE (director/writer: Aviva Kempner; cinematographers: Jerry Feldman/Kevin Hewitt/Tom Hurwitz/Tom Kaufman/Christopher Li/Scott Mumford; editor: Marion Sears Hunter; cast: Hank Greenberg, Virgil Trucks, Charlie Gehringer, Ira Berkow, Bob Feller, Dick Schaap, Alan Dershowitz, Walter Matthau, Shirley Povich; Runtime: 95; 1998)
Reviewed by Dennis Schwartz
It could be almost like a documentary that someone like ESPN would do, such as there 'When Baseball was a Game,' but in this Depression-era nostalgia piece about a genuine Jewish baseball superstar -- supposedly, the first one who openly said he was Jewish and wouldn't change his name -- the game becomes much more than what it is. It becomes a look at the social and political climate of America just as much as a baseball biography. This breezy documentary by the woman director, Aviva Kempner, which took her 12 years to get enough funds to release it, sings the praises of the likable original "Hammering Hank," a baseball Hall of Fame slugger and an heroic figure among his Jewish fans, and it relates the anti-Semitism that was present in the 1930s and 1940s. He was hailed as a messiah, a counter argument against those who never imagined a Jew could be such a physical player, a star in America's game. He broke the stereotype people had of Jews, because of his natural ability and physical presence. Alan Dershowitz, the infamous lawyer, says that he was the most important Jew of that period, giving hope to all the others through his accomplishments, allowing them to think that they could fit into the mainstream. He was articulate, a great player, a great role model, had a great work ethic, and though not a religious Jew, he realized how important his heritage was and how others looked up to him to do what is right, and he would not play on Yom Kippur, even during a pennant race, thusly gaining the respect of the American public.
Born in 1911 in the Bronx, to Roumanian immigrant parents, he grew to six-foot-four-inches while at James Monroe H.S. and attracted baseball scouts from the hometown New York Yankees and the Detroit Tigers, but wisely chose to sign with the Tigers because the great Lou Gehrig was a fixture at first base for the Yanks. Also, the Tiger scout promised his parents that they will let him go to college. But baseball was in Hank's blood and he signed a bonus to play with Detroit forgoing his education at N.Y.U., and after a short stint in the minors, he was called up to the big club for the 1933 season. He immediately fitted into the team, playing on an infield that had the great second baseman Charlie Gehringer, an infield that would eventually set a record for how many r.b.i's it would drive in. The team was good enough to win the pennant in 1934 and give life to a town that was hit hard by the Depression. Detroit was also noted for having two of the most vociferous anti-Semites, Henry Ford and Father Coughlin, and for some bigoted fans who couldn't accept him, calling him a sheenie and a kike from the stands. But most of the vicious taunts came from opposing teams, who all employed bench jockeys to call him anti-Semitic names. Of all the white ballplayers, he was picked on the most because of his religion. Interestingly, Jackie Robinson came up in 1947 the same year Hank called it quits. Jackie went on to break the color-line and was the only player to receive a harder time than Hank. It was as if Hank was passing the baton to Jackie.
He was the first ballplayer to earn $100,000, which came during his last season when he was suspiciously traded to the Pittsburgh Pirates on the whim of Tiger owner Mr. Briggs and not allowed to end his career with the Tigers.
Greenberg's accomplishments on the ballfield are legendary. During the 1938 season, he was chasing Babe Ruth's 60 home-run record, and ended up hitting 58 homers. He was the team leader that helped power the Tigers to consecutive pennants in 1934 and 1935, as the Tigers won their first World Series in '35. In 1945, after being the first ballplayer to enlist in the service, he returned from World War 11 to lead the Tigers to another pennant. Hank was proudest of the runs he drove in, in one year he drove in 183 runs, one less than the record held by Gehrig. He also became the first man to win most valuable player awards at two positions, first base and left field. There is no doubt about it, Hank was an inspiration to many people who needed such a heroic figure.
This film had a very skillful way of telling its story about a bygone era, doing it in an effortlessly grand style, with a tongue-in-cheek humor. Besides, any film that has a clip of the Marx Brothers breaking up a symphony orchestra to make it seem like a baseball game, has a good idea of when to be humorous and when to point out the seriousness of the slurs Hank had to go through. Hank was a class act, never openly complaining about what he went through, just talking about it because that was the real way it was. He never even complains about how the pitchers stopped pitching against him when he was closing in on the Babe. He became living proof of Jewish acceptance in America. This documentary makes use of the ones who loved Hank, by interviews with his family, his fans, other players, sports writers, and celebrities.
The only fault of the film, was that the director became too close to his subject, and perhaps, overdramatized the effects of Greenberg. Though he was the ultimate Jewish sports hero of the time, there were others who played important roles in allowing the Jews to become more easily accepted into the American mainstream. The conclusion of WW11 also had a lot to do with the change of America's attitude, though it is doubtful if anti-Semitism is through for good, as there are still other barriers in America that have to be broken down, such as having a Jewish president.

Hi all,
I know nothing is too expensive for the guy who just watches, and that
this implies a horrible nightmare of a build process, with exponential
number of scenarios to test and maintain, but I just have to say it:
Maybe these kind of alternative implementations could be factorised into
build options of the library, so double-plus-expert users could tweak
them to fit their problem domains?
It just seems like such a waste to permanently drop a setup which might
benefit some (agreed, probably not many) propagators.

Redux Fundamentals, Part 3: State, Actions, and ReducersWhat You'll Learn
- How to define state values that contain your app's data
- How to define action objects that describe what happens in your app
- How to write reducer functions that calculate updated state based on existing state and actions
Prerequisites
- Familiarity with key Redux terms and concepts like "actions", "reducers", "store", and "dispatching". (See Part 2: Redux Concepts and Data Flow for explanations of these terms.)
#
IntroductionIn Part 2: Redux Concepts and Data Flow, we looked at how Redux can help us build maintainable apps by giving us a single central place to put global app state. We also talked about core Redux concepts like dispatching action objects and using reducer functions that return new state values.
Now that you have some idea of what these pieces are, it's time to put that knowledge into practice. We're going to build a small example app to see how these pieces actually work together.
caution
The example app is not meant as a complete production-ready project. The goal is to help you learn core Redux APIs and usage patterns, and point you in the right direction using some limited examples. Also, some of the early pieces we build will be updated later on to show better ways to do things. Please read through the whole tutorial to see all the concepts in use.
#
Project SetupFor this tutorial, we've created a pre-configured starter project that already has React set up, includes some default styling, and has a fake REST API that will allow us to write actual API requests in our app. You'll use this as the basis for writing the actual application code.
To get started, you can open and fork this CodeSandbox:
You can also
clone the same project from this Github repo. After cloning the repo, you can install the tools
for the project with npm install
, and
start it with npm start
.
If you'd like to see the final version of what
we're going to build, you can check out
the
tutorial-steps
branch, or
look at the final version in this CodeSandbox.
#
Creating a New Redux + React ProjectOnce you've finished this tutorial, you'll probably want to try working on your own projects. We recommend using the Redux templates for Create-React-App as the fastest way to create a new Redux + React project. It comes with Redux Toolkit and React-Redux already configured, using a modernized version of the "counter" app example you saw in Part 1. This lets you jump right into writing your actual application code without having to add the Redux packages and set up the store.
If you want to know specific details on how to add Redux to a project, see this explanation:
Detailed Explanation: Adding Redux to a React
Project
The Redux template for CRA comes with Redux Toolkit and React-Redux already configured. If you're setting up a new project from scratch without that template, follow these steps:
-
Add the
@reduxjs/toolkit
andreact-redux
packages -
Create a Redux store using RTK's
configureStore
API, and pass in at least one reducer function -
Import the Redux store into your
application's entry point file (such as
src/index.js
) -
Wrap your root React component with the
<Provider>
component from React-Redux, like:
#
Exploring the Initial ProjectThis initial project is based on the standard Create-React-App project template, with some modifications.
Let's take a quick look at what the initial project contains:
-
/src
-
index.js
: the entry point file for the application. It renders the main<App>
component. -
App.js
: the main application component. -
index.css
: styles for the complete application -
/api
-
client.js
: a small AJAX request client that allows us to make GET and POST requests -
server.js
: provides a fake REST API for our data. Our app will fetch data from these fake endpoints later.
-
-
/exampleAddons
: contains some additional Redux addons that we'll use later in the tutorial to show how things work
-
If you load the app now, you should see a welcome message, but the rest of the app is otherwise empty.
With that, let's get started!
#
Starting the Todo Example AppOur example application will be a small "todo" application. You've probably seen todo app examples before - they make good examples because they let us show how to do things like tracking a list of items, handling user input, and updating the UI when that data changes, which are all things that happen in a normal application.
#
Defining RequirementsLet's start by figuring out the initial business requirements for this application:
-
The UI should consist of three main sections:
- An input box to let the user type in the text of a new todo item
- A list of all the existing todo items
- A footer section that shows the number of non-completed todos, and shows filtering options
- Todo list items should have a checkbox that toggles their "completed" status. We should also be able to add a color-coded category tag for a predefined list of colors, and delete todo items.
- The counter should pluralize the number of active todos: "0 items", "1 item", "3 items", etc
- There should be buttons to mark all todos as completed, and to clear all completed todos by removing them
-
There should be two ways to filter the displayed
todos in the list:
- Filtering based on showing "All", "Active", and "Completed" todos
- Filtering based on selecting one or more colors, and showing any todos whose tag that match those colors
We'll add some more requirements later on, but this is enough to get us started.
The end goal is an app that should look like this:
#
Designing the State ValuesOne of the core principles of React and Redux is that your UI should be based on your state. So, one approach to designing an application is to first think of all the state needed to describe how the application works. It's also a good idea to try to describe your UI with as few values in the state as possible, so there's less data you need to keep track of and update.
Conceptually, there are two main aspects of this application:
- The actual list of current todo items
- The current filtering options
We'll also need to keep track of the data the user is typing into the "Add Todo" input box, but that's less important and we'll handle that later.
For each todo item, we need to store a few pieces of information:
- The text the user entered
- The boolean flag saying if it's completed or not
- A unique ID value
- A color category, if selected
Our filtering behavior can probably be described with some enumerated values:
- Completed status: "All", "Active", and "Completed"
- Colors: "Red", "Yellow", "Green", "Blue", "Orange", "Purple"
Looking at these values, we can also say that the todos are "app state" (the core data that the application works with), while the filtering values are "UI state" (state that describes what the app is doing right now). It can be helpful to think about these different kinds of categories to help understand how the different pieces of state are being used.
#
Designing the State Structure
With Redux,
our application state is always kept in plain
JavaScript objects and arrays. That means you may not put other things into the
Redux state - no class instances, built-in JS types
like Map
/ Set
Promise
/ Date
, functions,
or anything else that is not plain JS data.
The root Redux state value is almost always a plain JS object, with other data nested inside of it.
Based on this information, we should now be able to describe the kinds of values we need to have inside our Redux state:
-
First, we need an array of todo item objects. Each
item should have these fields:
id
: a unique number-
text
: the text the user typed in completed
: a boolean flag-
color
: An optional color category
-
Then, we need to describe our filtering options. We
need to have:
- The current "completed" filter value
- An array of the currently selected color categories
So, here's what an example of our app's state might look like:
It's important to note that it's okay to have other state values outside of Redux!. This example is small enough so far that we actually do have all our state in the Redux store, but as we'll see later, some data really doesn't need to be kept in Redux (like "is this dropdown open?" or "current value of a form input").
#
Designing Actions
Actions are plain JavaScript objects
that have a type
field. As mentioned
earlier,
you can think of an action as an event that
describes something that happened in the
application.
In the same way that we designed the state structure based on the app's requirements, we should also be able to come up with a list of some of the actions that describe what's happening:
- Add a new todo entry based on the text the user entered
- Toggle the completed status of a todo
- Select a color category for a todo
- Delete a todo
- Mark all todos as completed
- Clear all completed todos
- Choose a different "completed" filter value
- Add a new color filter
- Remove a color filter
We normally put any extra data needed to describe
what's happening into the
action.payload
field. This could be a
number, a string, or an object with multiple fields
inside.
The Redux store doesn't care what the actual text
of the action.type
field is. However,
your own code will look at action.type
to
see if an update is needed. Also, you will frequently
look at action type strings in the Redux DevTools
Extension while debugging to see what's going on
in your app. So, try to choose action types that are
readable and clearly describe what's happening -
it'll be much easier to understand things when
you look at them later!
Based on that list of things that can happen, we can create a list of actions that our application will use:
-
{type: 'todos/todoAdded', payload: todoText}
-
{type: 'todos/todoToggled', payload: todoId}
-
{type: 'todos/colorSelected, payload: {todoId, color}}
-
{type: 'todos/todoDeleted', payload: todoId}
-
{type: 'todos/allCompleted'}
-
{type: 'todos/completedCleared'}
-
{type: 'filters/statusFilterChanged', payload: filterValue}
-
{type: 'filters/colorFilterChanged', payload: {color, changeType}}
In this case, the actions primarily have a single
extra piece of data apiece, so we can put that
directly in the action.payload
field. We
could have split the color filter behavior into two
actions, one for "added" and one for
"removed", but in this case we'll do it
as one action with an extra field inside specifically
to show that we can have objects as an action payload.
Like the state data, actions should contain the smallest amount of information needed to describe what happened.
#
Writing ReducersNow that we know what our state structure and our actions look like, it's time to write our first reducer.
Reducers are functions that take the
current state
and an
action
as arguments, and return a new
state
result. In other words,
(state, action) => newState
.
#
Creating the Root Reducer
A Redux app really only has one reducer function:
the "root reducer" function
that you will pass to createStore
later
on. That one root reducer function is responsible for
handling all of the actions that are
dispatched, and calculating what the
entire new state result should be every time.
Let's start by creating a
reducer.js
file in the
src
folder, alongside
index.js
and App.js
.
Every reducer needs some initial state, so we'll add some fake todo entries to get us started. Then, we can write an outline for the logic inside the reducer function:
A reducer may be called with undefined
as
the state value when the application is being
initialized. If that happens, we need to provide an
initial state value so the rest of the reducer code
has something to work with.
Reducers normally use ES6 default argument syntax
to provide initial state:
(state = initialState, action)
.
Next, let's add the logic to handle the
'todos/todoAdded'
action.
We know we need to check to see the current action's type matches that specific string. Then, we need to return a new object containing all of the state, even for the fields that didn't change.
That's... an awful lot of work to add one todo item to the state. Why is all this extra work necessary?
#
Rules of ReducersWe said earlier that reducers must always follow some special rules:
-
They should only calculate the new state value based
on the
state
andaction
arguments -
They are not allowed to modify the existing
state
. Instead, they must make immutable updates, by copying the existingstate
and making changes to the copied values. - They must not do any asynchronous logic or other "side effects"
tip
A "side effect" is any change to state or behavior that can be seen outside of returning a value from a function. Some common kinds of side effects are things like:
- Logging a value to the console
- Saving a file
- Setting an async timer
- Making an AJAX HTTP request
- Modifying some state that exists outside of a function, or mutating arguments to a function
-
Generating random numbers or unique random IDs
(such as
Math.random()
orDate.now()
)
Any function that follows these rules is also known as a "pure" function, even if it's not specifically written as a reducer function.
But why are these rules important? There's a few different reasons:
- One of the goals of Redux is to make your code predictable. When a function's output is only calculated from the input arguments, it's easier to understand how that code works, and to test it.
- On the other hand, if a function depends on variables outside itself, or behaves randomly, you never know what will happen when you run it.
- If a function modifies other values, including its arguments, that can change the way the application works unexpectedly. This can be a common source of bugs, such as "I updated my state, but now my UI isn't updating when it should!"
- Some of the Redux DevTools capabilities depend on having your reducers follow these rules correctly
The rule about "immutable updates" is particularly important, and worth talking about further.
#
Reducers and Immutable UpdatesEarlier, we talked about "mutation" (modifying existing object/array values) and "immutability" (treating values as something that cannot be changed).
warning
In Redux, our reducers are never allowed to mutate the original / current state values!
There are several reasons why you must not mutate state in Redux:
- It causes bugs, such as the UI not updating properly to show the latest values
- It makes it harder to understand why and how the state has been updated
- It makes it harder to write tests
- It breaks the ability to use "time-travel debugging" correctly
- It goes against the intended spirit and usage patterns for Redux
So if we can't change the originals, how do we return an updated state?
tip
Reducers can only make copies of the original values, and then they can mutate the copies.
We already saw that we can write immutable updates by hand, by using JavaScript's array / object spread operators and other functions that return copies of the original values.
This becomes harder when the data is nested. A critical rule of immutable updates is that you must make a copy of every level of nesting that needs to be updated.
However, if you're thinking that "writing immutable updates by hand this way looks hard to remember and do correctly"... yeah, you're right! :)
Writing immutable update logic by hand is hard, and accidentally mutating state in reducers is the single most common mistake Redux users make.
tip
In real-world applications, you won't have to write these complex nested immutable updates by hand. In Part 8: Modern Redux with Redux Toolkit, you'll learn how to use Redux Toolkit to simplify writing immutable update logic in reducers.
#
Handling Additional Actions
With that in mind, let's add the reducer logic
for a couple more cases. First, toggling a todo's
completed
field based on its ID:
And since we've been focusing on the todos state, let's add a case to handle the "visibility selection changed" action as well:
We've only handled 3 actions, but this is already getting a bit long. If we try to handle every action in this one reducer function, it's going to be hard to read it all.
That's why reducers are typically split into multiple smaller reducer functions - to make it easier to understand and maintain the reducer logic.
#
Splitting Reducers
As part of this,
Redux reducers are typically split apart based on
the section of the Redux state that they
update. Our todo app state currently has two top-level
sections: state.todos
and
state.filters
. So, we can split the large
root reducer function into two smaller reducers - a
todosReducer
and a
filtersReducer
.
So, where should these split-up reducer functions live?
We recommend organizing your Redux app folders and files based on "features" - code that relates to a specific concept or area of your application. The Redux code for a particular feature is usually written as a single file, known as a "slice" file, which contains all the reducer logic and all of the action-related code for that part of your app state.
Because of that,
the reducer for a specific section of the Redux app
state is called a "slice reducer". Typically, some of the action objects will be
closely related to a specific slice reducer, and so
the action type strings should start with the name of
that feature (like 'todos'
) and
describe the event that happened (like
'todoAdded'
), joined together
into one string
('todos/todoAdded'
).
In our project, create a new
features
folder, and then a
todos
folder inside that. Create a new
file named todosSlice.js
, and let's
cut and paste the todo-related initial state over into
this file:
Now we can copy over the logic for updating the todos. However, there's an important difference here. This file only has to update the todos-related state - it's not nested any more! This is another reason why we split up reducers. Since the todos state is an array by itself, we don't have to copy the outer root state object in here. That makes this reducer easier to read.
This is called reducer composition, and it's the fundamental pattern of building Redux apps.
Here's what the updated reducer looks like after we handle those actions:
That's a bit shorter and easier to read.
Now we can do the same thing for the visibility logic.
Create
src/features/filters/filtersSlice.js
, and
let's move all the filter-related code over
there:
We still have to copy the object containing the filters state, but since there's less nesting, it's easier to read what's happening.
info
To keep this page shorter, we'll skip showing how to write the reducer update logic for the other actions.
Try writing the updates for those yourself, based on the requirements described above.
If you get stuck, see the CodeSandbox at the end of this page for the complete implementation of these reducers.
#
Combining ReducersWe now have two separate slice files, each with its own slice reducer function. But, we said earlier that the Redux store needs one root reducer function when we create it. So, how can we go back to having a root reducer without putting all the code in one big function?
Since reducers are normal JS functions, we can import
the slice reducers back into reducer.js
,
and write a new root reducer whose only job is to call
the other two functions.
Note that each of these reducers is managing its own part of the global state. The state parameter is different for every reducer, and corresponds to the part of the state it manages.
This allows us to split up our logic based on features and slices of state, to keep things maintainable.
combineReducers
#
We can see that the new root reducer is doing the same thing for each slice: calling the slice reducer, passing in the slice of the state owned by that reducer, and assigning the result back to the root state object. If we were to add more slices, the pattern would repeat.
The Redux core library includes a utility called
combineReducers
, which does this same boilerplate step for us. We
can replace our hand-written
rootReducer
with a shorter one generated
by combineReducers
.
Now that we need combineReducers
,
it's time to actually install the Redux core
library:
Once that's done, we can import
combineReducers
and use it:
combineReducers
accepts an object where
the key names will become the keys in your root state
object, and the values are the slice reducer functions
that know how to update those slices of the Redux
state.
Remember, the key names you give to
combineReducers
decides what the key
names of your state object will be!
#
What You've LearnedState, Actions, and Reducers are the building blocks of Redux. Every Redux app has state values, creates actions to describe what happened, and uses reducer functions to calculate new state values based on the previous state and an action.
Here's the contents of our app so far:
Summary
-
Redux apps use plain JS objects, arrays, and
primitives as the state values
- The root state value should be a plain JS object
- The state should contain the smallest amount of data needed to make the app work
- Classes, Promises, functions, and other non-plain values should not go in the Redux state
-
Reducers must not create random values like
Math.random()
orDate.now()
- It's okay to have other state values that are not in the Redux store (like local component state) side-by side with Redux
-
Actions are plain objects with a
type
field that describe what happened-
The
type
field should be a readable string, and is usually written as'feature/eventName'
-
Actions may contain other values, which are
typically stored in the
action.payload
field - Actions should have the smallest amount of data needed to describe what happened
-
The
-
Reducers are functions that look like
(state, action) => newState
-
Reducers must always follow special rules:
-
Only calculate the new state based on
the
state
andaction
arguments -
Never mutate the existing
state
- always return a copy - No "side effects" like AJAX calls or async logic
-
Only calculate the new state based on
the
-
Reducers must always follow special rules:
-
Reducers should be split up to make them
easier to read
- Reducers are usually split based on top-level state keys or "slices" of state
- Reducers are usually written in "slice" files, organized into "feature" folders
-
Reducers can be combined together with the
Redux
combineReducers
function -
The key names given to
combineReducers
define the top-level state object keys
#
What's Next?We now have some reducer logic that will update our state, but those reducers won't do anything by themselves. They need to be put inside a Redux store, which can call the reducer code with actions when something has happened.
In Part 4: Store, we'll see how to create a Redux store and run our reducer logic.


Ross McCrorie in Rangers return as parent club run the rule over Portsmouth loanee
The defender has been ruled out for between four and six weeks with a hamstring injury.
by Chris Doyle, https://www.dailyrecord.co.uk/authors/chris-doyle/Ross McCrorie has returned to Rangers to begin his recovery from a hamstring injury he suffered with Portsmouth.
The Scotland-21 star has been ruled out for between four and six weeks as he was forced off in a man-of-the-match performance against Oxford United.
McCrorie had already been set to travel north of the border to link up with Scot Gemmill 's side during the international break.
And so the Ibrox club opted to carry out the initial diagnosis themselves as he starts his rehabilitation.
The 21-year-old will return to Fratton Park, however, as he looks to finish off his loan spell in stule once he regains full fitness.
Portsmouth boss Kenny Jackett said: "He went into Rangers for a scan and an initial assessment.
"He’ll be doing all of his rehab here. Ross was going up anyway to meet up with the Scotland under-21s.
"He got an initial assessment from his parent club.
"But, similarly, they’ve been in touch already and we’re pretty similar in our views of where it is.
"It’s quite a straightforward injury. He’ll be coming back here to do his rehab.
"Once things settle down for him a little bit then he’ll get back to work next week."
McCrorie's time at Portsmouth has been a mixed bag with the versatile defender in and out of the first team.
But he started to show his potential in recent weeks, starring at right-back, and it seemed like he was going to kick on for the rest of the season.
Jackett said following the Oxford game he was delighted with McCrorie's performance and his progress in recent weeks.
He added: "He brought a lot to our game and is learning all the time. In terms of bookings, he has to be careful and learn from that – and he can and will keep improving.
"He has found his feet now, there have been quite a number of changes in the summer and he is one of them. I am pleased with him.
"We persevered with him and there is a player there, definitely."


In 2010 the University of Minnesota Theater department produced a collaborative version of Aristophanes’ greek comedy “The Birds”. The overall design concept of this production was reused and recycled materials. Everything from the costumes to the hand held items were created from reusing all kinds of materials. I became involved by designing and constructing the two hand puppets used by the protagonists and a few other puppets for a couple scenes.
At first I constructed a prototype with the goal of creating a puppet that could easily be put on and taken off, but could also believably move like a bird. The solution was a hand puppet that was loose around the wrist. These prototypes lead to discoveries of small details that were then improved in the next iteration.
Inside construction of bird puppet prototype. The skeleton is constructed with cardboard and the beak is paper mache, keeping with the overall design theme.
The puppets also have articulating wings. Through research of the anatomy and mechanics of bird wings, as well as, trial and error I was able to construct pair of wings that folded in and layed on top of the arm and could also stretch out.
Once painted and finalized the bird puppets took to the stage where they blended seamlessly with the aesthetic of the other designers. Considering the cardboard construction and use, the puppets lasted in decent conditions the five week run.

As instructors, we constantly strive to improve our lectures and the class as a
whole. We provide anonymous "Tiny Feedback" opportunities to approximately 10% of the
class after each lecture, and the feedback helps us guage how CS 106B is going
on a bit more personal level.
We very much appreciate constructive feedback, and we want to know what is working
and what you would like to see us do differently. We will make every attempt to
improve the course as the quarter progresses.
Because of the anonymous nature of the feedback, we cannot reply directly to students,
which can be frustrating for both you and for us. So, we will use this page to
make comments on the feedback ("feedback feedback," as it were). We can't always
make the requested changes because of curricular restrictions and time constraits,
but we don't want you to feel that your feedback is going into a black hole, never
to be seen again. Trust us, we read every submission!
Furthermore, sometimes there are conflicting requests, and we may want to explain
why we are making the choices we are about this course. This is an iterative process
(see what we did there?), and we want to explain what changes we are making, and why.
Please let us know either anonymously or not if you have any other concerns about the
course, and we will address them as best we can. Thank you! -Chris, Chris, Anton, and the SLs.
p.s. Thank you for all your positive feedback! We will concentrate on the comments about
what we could improve here -- please don't think we just get negative feedback. :)
Feedback Feedback, 10 October, 2016
- "More about the assignment" -- it is tough to provide too much detail about
the assignment during class, due to time constraints. But, we will
always give at least an overview in class, and we will have YEAH
hours that will be taped and put online. You can also go to CLaIR hours,
which are designed to help with conceptual issues for assignements.
- "There was a lot of material -- it's rushed!" -- We have a ton of material to
cover in 10 weeks. Sometimes, we are too ambitious about what we can
go over in class. We will work on pacing during lectures.
- "It might be nice to be able to follow along a bit more interactively
in terms of coding in class," "More coding in class!" "More pieces of
code in class," (about 10 more similar sentiments) -- Wow. You want
more code in class! This is a tricky one, because code takes time to
write and process. If we have more code examples in class, we won't
be able to give some of the conceptual material the time it needs.
But, we will look at this and see what we can do. One idea might be
to have some extra code examples in other videos, where we can
take the time, and where you can pause the video, etc.
- "We spend too much time in class on conceptual stuff" -- Some CS 106B concepts are
hard. We will quickly get into more in-depth material that really
does take some explaining before we jump into coding with it.
But (see the previous comment), we will try and find more ways
to get more code examples to you.
- "Explain code stacks / queues / maps / sets more" -- this is primarily a
time limitation in class. But, sections are a great opportunity
to talk in more detail about the ideas. Also, the book is a terrific
reference. Finally, we almost always provide links to reference material
at the end of the slides.
- "While I understand it's difficult with such a large class size, I wish there
was a little more interaction between the students and the professors
during lecture" -- we do, too! Large lectures are not the best way to learn,
and we get that. We'll try to be more interactive with the class, but
we also hope that you are getting a lot out of your sections, where there
is more individual attention. Oh, and come to office hours to say "hi!"
- "I would have liked more time to be spent on the examples rather than the
definitions and theory; I just think the examples are more efficient
in helping understand the role of stacks/queues in the larger world of
computer science as well as their respective mechanisms." -- we'll try
to get more examples in class, but once we dig a bit deeper, we will need
to cover the concepts enough so that why we are writing the code we do
actually makes sense (and you understand it).
- "By making lots of references to scifi, you perpetuate the stereotype that people who like CS = people who like scifi (and traditional, mainstream, white-male-dominated scifi). There is already a cultural script that the people who "do CS" are, by and large, white and male and a certain brand of nerdy. Stanford, especially in its intro classes, should be doing all it can to make people from of all backgrounds -- especially those historically underrepresented in the field -- feel that there is space for them in computer science. (You did that on the first day by sharing the story of the person who used technology to check counterfeit medication!)" -- Thank you for the feedback.
There is a lot to unpack here, and we do consciously try to give examples,
homework problems, etc., that appeal to as many students as we can. We might
disagree that we have "made lots of references to scifi" -- yes, we have made
some, but we have also made references to literature, language, history, and others.
But, your point is well-taken, and we will strive to do better.
- "Stop saying under the covers plz" -- this caught us off-guard. We'll try to find better
analogies.
- "The explanation of ADTs was not so clear" -- sorry about that! If are explanations aren't
clear, please ask us to clarify them in office hours, on Piazza, or at the LaIR.
- "I understand that there's a lot of material to cover in a really short amount of time, but sometimes it's just so overwhelming trying to retain all the topics covered in class. We're always moving on to another topic before I have the chance to really soak in the details of the prior concept, so I wish we could focus on fewer ideas at a time but in greater detail. "
-- Yes, we don't like it, either. Take in what you can during lecture, read the book, watch
the video again (1.5x works well!), and ask questions in section, on Piazza and in LaIR.
We know this class is fast and furious, but we hope you can get a lot out of the non-lecture
portions of the class to make it work.
- "It'll be great if some comments can be added on the code" -- we do need to "practice
what we preach!" We will try and comment the example code better!
- "The slides seem a little verbose, or at least busy." -- We will work on making the
slides more clear. We do provide them online before class, so if you need more time
with each slide, feel free to download them and/or print them.
- "I want to hear more about bananagrams!" -- come to office hours! We love talking about
banangrams!
- "There were times when I think too much time was spent on the metaphors. For example, the concept of a set is not that hard to grasp, so I think it would be a better use of time to demonstrate more applications."
-- We try to have a mix, as some people really get metaphors, and it can be
a powerful tool. But, see above for how we will try and improve what we
cover in lecture.
- "Spend more time on going over the methods of the ADTs" -- Again, this is a time constraint issue.
All of the ADTs are referenced in the book and online. One suggestion: read about the
functions, and then try and code something that uses them! C++ classes do have a ton
of functions, and it is cool to dig into them to see what they can do.
- "I wish there was a slight bit more explanation on the difference between hashset/hashmap vs. set/map besides just the speed difference. Wasn't entirely clear on ordered/not ordered distinction" -- good point! We will cover the innards of both
types of ADTs at a later date, and it will all become clear! :)
- "I would love some mention about the book. Should I be reading it or not?" Yes! While the book is
not mandatory, it is strongly recommended that you read it. We always put the chapters
we are covering in class on the slides and web page. Sometimes the book covers much more
material than we get to in class -- you are not strictly responsible for material that
we don't mention or discuss in class.

Hawaii could have more than 10M annual visitors for 1st time
HONOLULU (AP) - Tourism officials say Hawaii is on track to have more than 10 million visitors in one year for the first time in the state’s history.
The Honolulu Star-Advertiser reported Thursday that Hawaii Tourism Authority data shows there have been nearly 8.7 million visitors through October.
The figure is a 5.5% increase over the 8.2 million arrivals through the same period last year, when the state’s annual count was 9.9 million visitors.
The authority says the 800,448 tourists who visited Hawaii in October was an increase of nearly 37,000 during the same month last year.
Officials say the 4.8% increase is part of a decade-long growth pattern.
Officials say the growth reflects more tourists traveling to the state from the U.S. mainland and countries including Japan and Canada.

National Espresso Day: Coffee the caffeinated beverage of choice for Canadians - Barriere Star Journal
by Shalu MehtaMost Canadians prefer drip coffee over other brews
Whether it’s a cup to go from a local cafe or java that’s been brewed at home, a recent report shows that coffee still reigns supreme in Canada.
SilverChef – a provider of new and used commercial kitchen equipment and funding – and Angus Reid partnered up to produce the report Coffee In Canada: An Unfiltered Look, which was released ahead of National Espresso Day on Nov. 23.
The report surveyed 1,010 Canadians online from Sept. 13 to 18. The respondents drink coffee at least once a moth and are members of the Angus Reid Forum.
READ ALSO: Cost concerns leading more java lovers to home brew over coffee shops: survey
It shows that drip coffee is the coffee of choice for Canadians, with 69 per cent of the respondents saying that is what they prefer. Canadians drink an average of 2.3 cups of coffee per day.
But the type of coffee and quantity consumed varies from province to province, with Alberta, Saskatchewan and Manitoba drinking the most coffee and Ontario drinking the least.
British Columbians are the biggest drip coffee and iced coffee drinkers in Canada, consuming the average of 2.3 cups per day.
Most coffee drinkers in Canada buy their beans or grounds at the supermarket but in the last year, one in three have changed their coffee purchase behaviour. Eighteen per cent now brew more coffee at home, 10 per cent changed the coffee they brew at home, nine per cent visit different coffee shops and eight per cent visit more coffee shops.
READ ALSO: Esquimalt welcomes first coffee roastery
Regardless of where or how Canadians get their caffeine fix, the report shows quality is key to consumers followed closely by price. These two factors have become more important to one-quarter of consumers than they were one year ago.
The majority of Canadians consume their cup of joe with environmental impacts in mind as well but millennials are most likely to do so when selecting a to-go cup, the origin of their coffee bean or which milk they use in their coffee.
With more than three-quarters of Canadians preferring coffee over tea, it’s clear the jitter-inducing bean juice is the go-to caffeinated drink for consumers.

Martin Keown: Arsenal should consider Mauricio Pochettino
Former Arsenal and England defender Martin Keown believes that his former team should consider a move for ex-Tottenham Hotspur manager Mauricio Pochettino, if they sack Unai Emery.
The Gunners have won just one of their last seven matches - against Vitoria Guimaraes - and pressure is beginning to mount on Emery.
Despite Arsenal's fierce rivalry with Spurs, Keown believes that the Gunners "should be seriously considering Pochettino" if the Emirates Stadium hot seat becomes vacant.
"There's no need to panic at Arsenal, we are getting close to panic by the way, because we're not having the best of seasons, but the powers that be at the top of the club should be seriously considering Pochettino," Keown, who was part of Arsenal's Invincibles of 2003/04, told the Daily Mail.
" I have a lot of admiration for what he did at Tottenham, the way he nurtured those young players and he didn't spend a great deal of money."
Ex-Spurs manager Harry Redknapp agreed, telling talkSPORT: "You think the Arsenal fans wouldn't love him there?
"If you go in there and start winning football matches, they would have taken Saddam Hussein...
"If you start winning every week, they're singing 'there's only one Saddam'."
Redknapp added that Pochettino had expected to replace Jose Mourinho - who has since replaced him at Spurs - at Old Trafford last season.
Redknapp told Sky Sports: "I think he wanted the Manchester United job last year.
"I know for a fact that he thought he had the job at United, but he didn't get it."
Pochettino could still end up in Manchester, though, with Trevor Sinclair suggesting that the 47-year-old would be the "perfect candidate" should Pep Guardiola decide to leave the club.
The former Manchester City winger told talkSPORT: "I'm looking at the situation at Man City, and I haven't heard anything, but Pep Guardiola looks irritated this season.
"Not with the club, not with the owners, not with his team. He looks like he's had enough of VAR. And, he's been at the club a few years and he doesn't tend to hang about.
"If he does walk away - I'm not saying he will - but if he did walk away from Man City in the summer, I think Pochettino would be the perfect candidate to come in and take that hot seat."

./configure --enable-static --disable-dynamic && make
in a clean source directory builds the static and dynamic libs (by which I mean
the .a and .so files) and links the example binaries dynamically, e.g.

I think they should be completely static to avoid problems with different
versions of libstdc++ on different systems, especially since this library is not
strictly required.

Hello there! My name is Saudia and I am breaking my way into technology! I have been coding for a few months and am gaining experience outside of the learning environment. I have a background in investigations and as a way to make myself more marketable, I decided to branch out into completely unfamiliar territory: the art of coding.
In addition to learning Javascript, HTML, and CSS3 as it comes, I am also diving into Microsoft Excel and Python. Once I feel as comfortable as I am with HTML and CSS, I will be moving on to SQL. After that, who knows? Maybe I will conquer the world! (just kidding, but it is a thought!) Right now, I am seeking to gain more experience in web design and development.

Using front matter is one way that you can specify configuration in the pages and posts for your site.
Setting things
like a default layout, or customizing the title, or specifying a more precise date/time for the post
can all be added to your page or post front matter.
笔记：在一个page当中，我们可以使用front matter来定义变量，增加“灵活性”
Often times, you will find that you are repeating a lot of configuration options.
Setting the same layout in each file, adding the same category - or categories - to a post, etc.
You can even add custom variables like author names,
which might be the same for the majority of posts on your blog.
笔记：但是，在page当中使用front matter来定义变量，也有新的问题产生，那就是“繁琐”
Instead of repeating this configuration each time you create a new post or page,
Jekyll provides a way to set these defaults in the site configuration.
To do this, you can specify site-wide defaults using the defaults
key
in the _config.yml
file in your project's root directory.
笔记：相应的，解决方法就是在_config.yml中定义defaults部分的内容
The defaults
key holds an array of scope/values
pairs
that define what defaults should be set for a particular file path, and optionally, a file type in that path.
Let's say that you want to add a default layout to all pages and posts in your site.
You would add this to your _config.yml
file:
defaults: - scope: path: "" # an empty string here means all files in the project values: layout: "default"
Here, we are scoping the values
to any file that exists in the path scope
.
Since the path
is set as an empty string, it will apply to all files in your project.
You probably don't want to set a layout on every file in your project
- like css files, for example -
so you can also specify a type
value under the scope
key.
defaults: - scope: path: "" # an empty string here means all files in the project type: "posts" # previously `post` in Jekyll 2.2. values: layout: "default"
Now, this will only set the layout for files where the type is posts
.
The different types that are available to you are pages
, posts
, drafts
or any collection in your site.
While type
is optional, you must specify a value for path
when creating a scope/values
pair.
As mentioned earlier, you can set multiple scope/values
pairs for defaults
.
defaults: - scope: path: "" type: "pages" values: layout: "my-site" - scope: path: "projects" type: "pages" # previously `page` in Jekyll 2.2. values: layout: "project" # overrides previous default layout author: "Mr. Hyde"
With these defaults, all pages would use the my-site
layout.
Any html files that exist in the projects/
folder will use the project
layout, if it exists.
Those files will also have the page.author
liquid variable set to Mr. Hyde
.
collections: my_collection: output: true defaults: - scope: path: "" type: "my_collection" # a collection in your site, in plural form values: layout: "default"
In this example, the layout
is set to default
inside the
collection with the name my_collection
.
It is also possible to use glob patterns (currently limited to patterns that contain *
) when matching defaults.
For example, it is possible to set specific layout for each special-page.html
in any subfolder of section
folder.
collections: my_collection: output: true defaults: - scope: path: "section/*/special-page.html" values: layout: "specific-layout"
Jekyll will apply all of the configuration settings
you specify in the defaults
section of your _config.yml
file.
You can choose to override settings from other scope/values
pair
by specifying a more specific path for the scope
.
You can see that in the second to last example above.
First, we set the default page layout to my-site
.
Then, using a more specific path, we set the default layout for pages in the projects/
path to project
.
This can be done with any value that you would set in the page or post front matter.
Finally, if you set defaults in the site configuration by adding a defaults
section to your _config.yml
file,
you can override those settings in a post or page file.
All you need to do is specify the settings in the post or page front matter.
For example:
# In _config.yml ... defaults: - scope: path: "projects" type: "pages" values: layout: "project" author: "Mr. Hyde" category: "project" ...
# In projects/foo_project.md --- author: "John Smith" layout: "foobar" --- The post text goes here...
The projects/foo_project.md
would have the layout
set to foobar
instead of project
and the author
set to John Smith
instead of Mr. Hyde
when the site is built.


Active Model – model interfaces for Rails
Active Model provides a known set of interfaces for usage in model classes. They allow for Action Pack helpers to interact with non-Active Record models, for example. Active Model also helps with building custom ORMs for use outside of the Rails framework.
Prior to Rails 3.0, if a plugin or gem developer wanted to have an object
interact with Action Pack helpers, it was required to either copy chunks of
code from Rails, or monkey patch entire helpers to make them handle objects
that did not exactly conform to the Active Record interface. This would
result in code duplication and fragile applications that broke on upgrades.
Active Model solves this by defining an explicit API. You can read more
about the API in ActiveModel::Lint::Tests
.
Active Model provides a default module that implements the basic API
required to integrate with Action Pack out of the box:
ActiveModel::Model
.
class Person
include ActiveModel::Model
attr_accessor :name, :age
validates_presence_of :name
end
person = Person.new(name: 'bob', age: '18')
person.name # => 'bob'
person.age # => '18'
person.valid? # => true
It includes model name introspections, conversions, translations and
validations, resulting in a class suitable to be used with Action Pack. See
ActiveModel::Model
for more examples.
Active Model also provides the following functionality to have ORM-like behavior out of the box:
-
Add attribute magic to objects
class Person include ActiveModel::AttributeMethods attribute_method_prefix 'clear_' define_attribute_methods :name, :age attr_accessor :name, :age def clear_attribute(attr) send("#{attr}=", nil) end end person.clear_name person.clear_age
-
Callbacks for certain operations
class Person extend ActiveModel::Callbacks define_model_callbacks :create def create run_callbacks :create do # Your create action methods here end end end
This generates
before_create
,around_create
andafter_create
class methods that wrap your create method. -
Tracking value changes
class Person include ActiveModel::Dirty attr_accessor :name end person = Person.new person.name # => nil person.changed? # => false person.name = 'bob' person.changed? # => true person.changed # => ['name'] person.changes # => { 'name' => [nil, 'bob'] } person.name = 'robert' person.save person.previous_changes # => {'name' => ['bob, 'robert']}
-
Adding
errors
interface to objectsExposing error messages allows objects to interact with Action Pack helpers seamlessly.
class Person def initialize @errors = ActiveModel::Errors.new(self) end attr_accessor :name attr_reader :errors def validate! errors.add(:name, "cannot be nil") if name.nil? end def self.human_attribute_name(attr, options = {}) "Name" end end person.errors.full_messages # => ["Name cannot be nil"]
-
Model name introspection
class NamedPerson extend ActiveModel::Naming end NamedPerson.model_name # => "NamedPerson" NamedPerson.model_name.human # => "Named person"
-
Making objects serializable
ActiveModel::Serialization provides a standard interface for your object to provide
to_json
orto_xml
serialization.class SerialPerson include ActiveModel::Serialization attr_accessor :name def attributes {'name' => name} end end s = SerialPerson.new s.serializable_hash # => {"name"=>nil} class SerialPerson include ActiveModel::Serializers::JSON end s = SerialPerson.new s.to_json # => "{\"name\":null}" class SerialPerson include ActiveModel::Serializers::Xml end s = SerialPerson.new s.to_xml # => "<?xml version=\"1.0\" encoding=\"UTF-8\"?>\n<serial-person...
-
Internationalization (i18n) support
class Person extend ActiveModel::Translation end Person.human_attribute_name('my_attribute') # => "My attribute"
-
Validation support
class Person include ActiveModel::Validations attr_accessor :first_name, :last_name validates_each :first_name, :last_name do |record, attr, value| record.errors.add attr, 'starts with z.' if value.to_s[0] == ?z end end person = Person.new person.first_name = 'zoolander' person.valid? # => false
-
Custom validators
class ValidatorPerson include ActiveModel::Validations validates_with HasNameValidator attr_accessor :name end class HasNameValidator < ActiveModel::Validator def validate(record) record.errors[:name] = "must exist" if record.name.blank? end end p = ValidatorPerson.new p.valid? # => false p.errors.full_messages # => ["Name must exist"] p.name = "Bob" p.valid? # => true

A Non-Metric Space Library ('NMSLIB' <https://github.com/searchivarius/nmslib>) wrapper, which according to the authors "is an efficient cross-platform similarity search library and a toolkit for evaluation of similarity search methods. The goal of the 'NMSLIB' <https://github.com/searchivarius/nmslib> Library is to create an effective and comprehensive toolkit for searching in generic non-metric spaces. Being comprehensive is important, because no single method is likely to be sufficient in all cases. Also note that exact solutions are hardly efficient in high dimensions and/or non-metric spaces. Hence, the main focus is on approximate methods". The wrapper also includes Approximate Kernel k-Nearest-Neighbor functions based on the 'NMSLIB' <https://github.com/searchivarius/nmslib> 'Python' Library.

Enable this to export your level data in a secondary super simple format, ideal for quick integration in ANY existing engine.
You will get:
- one PNG per layer,
- one composite PNG per level,
- a single JSON file per level containing main level infos and entities.
Enable this to separate the main project file (containing settings, definitions etc.) from the level files (one file per level, stored in a sub-folder).
Saving times are also faster with separate levels enabled because unmodified data is cached and not re-wrote.
This option allows you to export 'flattened' PNG screenshots of the levels in addition to the JSON data, every time you save the project.
Also export level backgrounds
Enable this to export PNGs that will include the level background color or image.
PNG file names
Enable this to create Tiled TMX files (one per level) in a sub folder, every time you save your project.
Warning: this Tiled export is made for quick integration with game frameworks that don't support LDtk yet, but it comes with some limitations!
See the link for more info.
If checked, the project file will use the official extension ".::ext::" instead of the standard ".json".
This setting is recommended for proper file identification and association on your system.
(recommended)
Everytime you save your project, an extra backup copy will be created in a subfolder.
Backups will obviously increase saving time and disk usage, but that's not a reason for not using them ;)
Note: in case of a crash, a special backup will be created, even if this setting is disabled.
Max backup files: It's recommended to enable backups for large or important projects.
Enable this to save project JSON file without any "pretty" formatting (ie. white spaces and indentation).
This is NOT necessarily recommended if your project is stored on a versioning system (git, svn etc.) because this could cause issues with diffs and merging operations.
Only use this option if you really need to reduce the project files size.
This option allows to customize the constraints on "identifiers" format. It's recommended to keep the default "First letter uppercased" format, unless you know what you're doing.
User custom commands
A list of custom commands that will be executed by LDtk in various situations.
The working directory for all these commands is the project directory.
If multiple commands are to be ran at a given moment (eg. before saving), they will be executed in order of appearance here.
This project is allowed to run user commands on your computer. Remove authorization
This project is NOT allowed to run user commands on your computer. Unblock it
Workspace settings
Set the default grid size when creating new layers in this project.
px
Set the default width/height when creating new entities in this project.
x px
You can customize the default naming convention for all level identifiers.
Note that level identifiers must be UNIQUE and as such, an extra auto-increment might be added to levels sharing getting the same name, to avoid collisions.
Also, remember the identifiers should only contain letters, numbers, "-" and "_".
Base background color of the project workspace
Default background color of all levels.
Default entity pivot point position for all entities.
See the Entity panel for more information about the pivot point.
Advanced project settings
Advanced options are not recommended for most users as they might break compatibility with older game APIs. Please make sure you know what you're doing before using any of them!

“Think simple” as my old master used to say - meaning reduce the whole of its parts into the simplest terms, getting back to first principles.
—Frank Lloyd Wright
Horizon holds several key values at the core of its design and architecture:
- Core Support: Out-of-the-box support for all core OpenStack projects.
- Extensible: Anyone can add a new component as a “first-class citizen”.
- Manageable: The core codebase should be simple and easy-to-navigate.
- Consistent: Visual and interaction paradigms are maintained throughout.
- Stable: A reliable API with an emphasis on backwards-compatibility.
- Usable: Providing an awesome interface that people want to use.
The only way to attain and uphold those ideals is to make it easy for developers to implement those values.
Horizon started life as a single app to manage OpenStack’s compute project. As such, all it needed was a set of views, templates, and API calls.
From there it grew to support multiple OpenStack projects and APIs gradually, arranged rigidly into “dash” and “syspanel” groupings.
During the “Diablo” release cycle an initial plugin system was added using signals to hook in additional URL patterns and add links into the “dash” and “syspanel” navigation.
This incremental growth served the goal of “Core Support” phenomenally, but left “Extensible” and “Manageable” behind. And while the other key values took shape of their own accord, it was time to re-architect for an extensible, modular future.
At its core, Horizon should be a registration pattern for applications to hook into. Here’s what that means and how it is implemented in terms of our values:
Horizon ships with three central dashboards, a “User Dashboard”, a “System Dashboard”, and a “Settings” dashboard. Between these three they cover the core OpenStack applications and deliver on Core Support.
The Horizon application also ships with a set of API abstractions for the core OpenStack projects in order to provide a consistent, stable set of reusable methods for developers. Using these abstractions, developers working on Horizon don’t need to be intimately familiar with the APIs of each OpenStack project.
A Horizon dashboard application is based around the Dashboard class that provides a consistent API and set of capabilities for both core OpenStack dashboard apps shipped with Horizon and equally for third-party apps. The Dashboard class is treated as a top-level navigation item.
Should a developer wish to provide functionality within an existing dashboard (e.g. adding a monitoring panel to the user dashboard) the simple registration pattern makes it possible to write an app which hooks into other dashboards just as easily as creating a new dashboard. All you have to do is import the dashboard you wish to modify.
Within the application, there is a simple method for registering a Panel (sub-navigation items). Each panel contains the necessary logic (views, forms, tests, etc.) for that interface. This granular breakdown prevents files (such as api.py) from becoming thousands of lines long and makes code easy to find by correlating it directly to the navigation.
By providing the necessary core classes to build from, as well as a solid set of reusable templates and additional tools (base form classes, base widget classes, template tags, and perhaps even class-based views) we can maintain consistency across applications.
By architecting around these core classes and reusable components we create an implicit contract that changes to these components will be made in the most backwards-compatible ways whenever possible.
Ultimately that’s up to each and every developer that touches the code, but if we get all the other goals out of the way then we are free to focus on the best possible experience.
