UGA Photographer Shares Picture of RB Brian Herrien Right Before She Got KO’D On Sidelines (PIC)
by Darrelle LincolnNo matter what, you must always get the shot. That is the creed of the photojournalist.
Chamberlain Smith definitely lived by that motto.
On Tuesday, the UGA photographer who got knocked unconscious on the Auburn sidelines over the weekend, took to Twitter and tweeted out the last picture she took right before she got hit.
It was an extreme closeup of Georgia running back Brian Herrien.
Herrien himself also gave his thanks after the photo was released.

Herrien would go on to score on a five-yard screen pass on the very next play to give Georgia a 13-0 lead 20 seconds before halftime. The No. 4 Bulldogs went on to defeat the No. 16 Auburn Tigers by the score of 21-14.

So this website is all about how a boy named Ivan tried his best to survive in Digital Fabrication Course
And guess what? That is me :) I am Ivan, a sophomore in Western Reserve Academy
I am from Hong Kong, I am 16 years old.
You can consider me a thinker, I really like creating stuff and art.
But sometimes I just can't think of any good ideas under pressure. I have high standards for myself, for every project. So sometimes it can be frustrating...
I am here is explore and learn something about new technologies! I am most excited about making a clock of my own, because I can combine ideas together and draw on the clock at the same time
I love making designs, but not as much when it comes to coding...
So I am gonna keep this short, hopefully you appreciate my projects :D

Requirements Coverage
User Should be able to search Restaurant ,Apartments and events in the city he wants.
User should be able to see reviews,details of selected restaurant and it's menu.if available.
- Restaurant details page show,how manny users have liked it,it shows menu and reviews if available,if not then shows nothing.
User should be able to review an restaurant and add a restaurant and other user as favorite only after login.
- Here I have taken notice that user should not be able to save same restaurant or user as favorite.
- Submit field in login modal and review form are disabled if required fields are not filled.
- The user will be asked to login for the first time when he attempts to post review or attempt to add a restaurant or user to favorite.
User should be able to see his reviews ,favorite restaurants and users in the profile.
- Here I have made facility to visit the restaurant or user profile when you click on the blue link telling their name
User should be able to see his favorite user's reviews ,favorite restaurants and users through his profile.
User should be able to see his other user's reviews ,favorite restaurants and users through restaurant details page.
- When you click on blue link,specifying user email address in review section you will be redirected to user's page.For example,uf we click<EMAIL_ADDRESS>as shown in picture given below.
- User should be able to delete his reviews ,favorite restaurants and users through his profile.
- All options work the same as for deleting review,In below example I am attempting to delete review of BlackJack Pastabar,of date 8th december.Once you delete it changes are reflected both in your profile page and restaurant page.
- User Should be able to update his profile(Name and Location Only).
- I have made update modal,similar as login modal,if the field is invalid,the border of textbox is red,else green,button becomes active only if both name and location are entered.On successful update changes are seen in the profile.
By the example explained above,we can assume that all our functional requirements have been met,there are some small errors here and there,but most of the functionality works fine.
As of non functional requirements is concerned,application supports multi user login ,follow minimalist design and can be used at any point of time,hence they are also met.
A few issues in the project:
- Somehow home page is not acting responsive,the bottom content goes beyond div area on smaller screens.
- On home page in google maps,marker widow for restaurant gets closed on click but room's marker window doesn't close or take too long.

--- layout: post title: "Non-exceptional averages" description: "How do you code without exceptions? Here's one example." date: 2020-02-03 6:38 UTC tags: [Software Design] --- {% include JB/setup %}
{{ page.description }}
Encouraging object-oriented programmers to avoid throwing exceptions is as fun as telling them to renounce null references. To be fair, exception-throwing is such an ingrained feature of C#, Java, C++, etcetera that it can be hard to see how to do without it.
To be clear, I don't insist that you pretend that exceptions don't exist in languages that have them. I'm also not advocating that you catch all exceptions in order to resurface them as railway-oriented programming. On the other hand, I do endorse the generally good advice that you shouldn't use exceptions for control flow.
What can you do instead? Despite all the warnings against railway-oriented programming, Either is still a good choice for a certain kind of control flow. Exceptions are for exceptional situations, such as network partitions, running out of memory, disk failures, and so on. Many run-time errors are both foreseeable and preventable. Prefer code that prevents errors.
There's a few ways you can do that. One of them is to protect invariants by enforcing pre-conditions. If you have a static type system, you can use the type system to prevent errors.
How would you calculate the average of a set of durations? You might, for example, need to calculate average duration of message handling for a polling consumer. C# offers many built-in overloads of the Average extension method, but none that calculates the average of TimeSpan values.
How would you write that method yourself?
It's not a trick question.
Based on my experience coaching development teams, this is a representative example:
public static TimeSpan Average(this IEnumerable<TimeSpan> timeSpans) { var sum = TimeSpan.Zero; var count = 0; foreach (var ts in timeSpans) { sum += ts; count++; } return sum / count; }
This gets the job done in most situations, but it has two error modes. It doesn't work if timeSpans
is empty, and it doesn't work if it's infinite.
When the input collection is empty, you'll be trying to divide by zero, which isn't allowed. How do you deal with that? Most programmers I've met just shrug and say: don't call the method with an empty collection. Apparently, it's your responsibility as the caller. You have to memorise that this particular Average
method has that particular precondition.
I don't think that's a professional position. This puts the burden on client developers. In a world like that, you have to learn by rote the preconditions of thousands of APIs.
What can you do? You could add a Guard Clause to the method.
Adding a Guard Clause doesn't really make the method much easier to reason about for client developers, but at least it protects an invariant.
public static TimeSpan Average(this IEnumerable<TimeSpan> timeSpans) { if (!timeSpans.Any()) throw new ArgumentOutOfRangeException( nameof(timeSpans), "Can't calculate the average of an empty collection."); var sum = TimeSpan.Zero; var count = 0; foreach (var ts in timeSpans) { sum += ts; count++; } return sum / count; }
Don't get me wrong. I often write code like this because it makes it easier for me as a library developer to reason about the rest of the method body. On the other hand, it basically just replaces one run-time exception with another. Before I added the Guard Clause, calling Average
with an empty collection would cause it to throw an OverflowException
; now it throws an ArgumentOutOfRangeException
.
From client developers' perspective, this is only a marginal improvement. You're still getting no help from the type system, but at least the run-time error is a bit more informative. Sometimes, that's the best you can do.
The Average
method has two preconditions, but we've only addressed one. The other precondition is that the input timeSpans
must be finite. Unfortunately, this compiles:
static IEnumerable<T> InfinitelyRepeat<T>(T x) { while (true) yield return x; } var ts = new TimeSpan(1, 2, 3, 4); var tss = InfinitelyRepeat(ts); var avg = tss.Average();
Since tss
infinitely repeats ts
, the Average
method call (theoretically) loops forever; in fact it quickly overflows because it keeps adding TimeSpan
values together.
Infinite collections aren't allowed. Can you make that precondition explicit?
I don't know of a way to test that timeSpans
is finite at run time, but I can change the input type:
public static TimeSpan Average(this IReadOnlyCollection<TimeSpan> timeSpans) { if (!timeSpans.Any()) throw new ArgumentOutOfRangeException( nameof(timeSpans), "Can't calculate the average of an empty collection."); var sum = TimeSpan.Zero; foreach (var ts in timeSpans) sum += ts; return sum / timeSpans.Count; }
Instead of accepting any IEnumerable<TimeSpan>
as an input argument, I've now constrained timeSpans
to an IReadOnlyCollection<TimeSpan>
. This interface has been in .NET since .NET 4.5 (I think), but it lives a quiet existence. Few people know of it.
It's just IEnumerable<T>
with an extra constraint:
public interface IReadOnlyCollection<T> : IEnumerable<T> { int Count { get; } }
The Count
property strongly implies that the IEnumerable<T>
is finite. Also, that the value is an int
implies that the maximum size of the collection is 2,147,483,647. That's probably going to be enough for most day-to-day use.
You can no longer pass an infinite stream of values to the Average
method. It's simply not going to compile. That both communicates and protects the invariant that infinite collections aren't allowed. It also makes the implementation code simpler, since the method doesn't have to count the elements. That information is already available from timeSpans.Count
.
If a type can address one invariant, can it also protect the other?
You can change the input type again. Here I've used this NotEmptyCollection<T> implementation:
public static TimeSpan Average(this NotEmptyCollection<TimeSpan> timeSpans) { var sum = timeSpans.Head; foreach (var ts in timeSpans.Tail) sum += ts; return sum / timeSpans.Count; }
Now client code can no longer call the Average
method with an empty collection. That's also not going to compile.
You've replaced a run-time check with a compile-time check. It's now clear to client developers who want to call the method that they must supply a NotEmptyCollection<TimeSpan>
, instead of just any IReadOnlyCollection<TimeSpan>
.
You can also simplify the implementation code:
public static TimeSpan Average(this NotEmptyCollection<TimeSpan> timeSpans) { var sum = timeSpans.Aggregate((x, y) => x + y); return sum / timeSpans.Count; }
How do we know that NotEmptyCollection<T>
contains at least one element? The constructor enforces that constraint:
public NotEmptyCollection(T head, params T[] tail) { if (head == null) throw new ArgumentNullException(nameof(head)); this.Head = head; this.Tail = tail; }
But wait, there's a Guard Clause and a throw
there! Have we even accomplished anything, or did we just move the throw
around?
A Guard Clause is a kind of validation. It validates that input fulfils preconditions. The problem with validation is that you have to repeat it in various different places. Every time you receive some data as an input argument, it may or may not have been validated. A receiving method can't tell. There's no flag on a string, or a number, or a collection, which is set when data has been validated.
Every method that receives such an input will have to perform validation, just to be sure that the preconditions hold. This leads to validation code being duplicated over a code base. When you duplicate code, you later update it in most of the places it appears, but forget to update it in a few places. Even if you're meticulous, a colleague may not know about the proper way of validating a piece of data. This leads to bugs.
As Alexis King explains in her Parse, don’t validate article, 'parsing' is the process of validating input of weaker type into a value of a stronger type. The stronger type indicates that validation has happened. It's like a Boolean flag that indicates that, yes, the data contained in the type has been through validation, and found to hold.
This is also the case of NotEmptyCollection<T>
. If you have an object of that type, you know that it has already been validated. You know that the collection isn't empty. Even if you think that it looks like we've just replaced one exception with another, that's not the point. The point is that we've replaced scattered and unsystematic validation code with a single verification step.
You may still be left with the nagging doubt that I didn't really avoid throwing an exception. I think that the NotEmptyCollection<T>
constructor strikes a pragmatic balance. If you look only at the information revealed by the type (i.e. what an IDE would display), you'll see this when you program against the class:
public NotEmptyCollection(T head, params T[] tail)
While you could, technically, pass null
as the head
parameter, it should be clear to you that you're trying to do something you're not supposed to do: head
is not an optional argument. Had it been optional, the API designer should have provided an overload that you could call without any value. Such a constructor overload isn't available here, so if you try to cheat the compiler by passing null
, don't be surprised to get a run-time exception.
For what it's worth, I believe that you can only be pragmatic if you know how to be dogmatic. Is it possible to protect NotEmptyCollection<T>
's invariants without throwing exceptions?
Yes, you could do that by making the constructor private
and instead afford a static factory method that returns a Maybe or Either value. In Haskell, this is typically called a smart constructor. It's only a few lines of code, so I could easily show it here. I chose not to, though, because I'm concerned that readers will interpret this article the wrong way. I like Maybe and Either a lot, but I agree with the above critics that it may not be idiomatic in object-oriented languages.
Encapsulation is central to object-oriented design. It's the notion that it's an object's own responsibility to protect its invariants. In statically typed object-oriented programming languages, objects are instances of classes. Classes are types. Types encapsulate invariants; they carry with them guarantees.
You can sometimes model invariants by using types. Instead of performing a run-time check on input arguments, you can declare constructors and methods in such a way that they only take arguments that are already guaranteed to be valid.
That's one way to reduce the amount of exceptions that your code throws.
Comments
Great post. I too prefer to avoid exceptions by strengthening preconditions using types.
I am not sure what you mean here. My best guess is that you are saying that this code would execute forever except that it will overflow, which will halt the execution. However, I think the situation is ambiguous. This code is impure because, as the Checked and Unchecked documentation says, its behavior depends on whether or not the
-checked
compiler option is given. This dependency on the compiler option can be removed by wrapping this code in a checked or unchecked block, which would either result in a thrown exception or an infinite loop respectively.There is a third error mode, and it exists in every implementation you gave. The issue of overflow is not restricted to the case of infinitely many
TimeSpan
s. It only takes two. I know of or remember this bug as "the last binary search bug". That article shows how to correctly compute the average of two integers without overflowing. A correct implementation for computing the average of more than two integers is to map each element to a mixed fraction with the count as the divisor and then appropriately aggregate those values. The implementation given in this Quora answer seems correct to me.I know all this is unrelated to the topic of your post, but I also know how much you prefer to use examples that avoid this kind of accidental complexity. Me too! However, I still like your example and can't think of a better one at the moment.
Tyson, thank you for writing. Given an infinite stream of values, the method throws an
OverflowException
. This is becauseTimeSpan
addition explicitly does that:This little snippet from C# Interactive also illustrates the third error mode that I hadn't considered. Good point, that.
Ah, yes. You are correct. Thanks for pointing out my mistake. Another way to verify this is inspecting
TimeSpan.Add
in Mircosoft's reference source. I should have done those checks before posting. Thanks again!

Environmental – Property Redevelopment (IV.7.)
Historic
and cultural research plays a major part in this stage of development.
- Since the community already has a preconceived idea of the use for that site, shifting their expectations is
critical for acceptance.
- Although a site may not have had a major impact on the community at large, it may have great importance to a few
members personally.
- It is important to engage in those conversations and understand how your development may incorporate their
input.
- Again, this will help gain acceptance into the community and may help to expedite municipal approvals.
- On that same note, understanding existing historic designations and zoning restrictions at the beginning of the
stage will help to form a redevelopment plan that meets the municipalities’ expectations and requirements for a
faster approval process.
- That faster approval process can also help mitigate costs of marketing strategies, design revisions, and lawyer
fees.
Previous uses affect future development, positively or negatively must be identified.
Previously constructed improvement affect future development, positively or negatively must be

Supernova (2000, PG-13)
Directed by Thomas Lee
Written by David Campbell Wilson
Story by William Malone and Daniel Chuba
Starring James Spader, Angela Bassett, Robert Forster, Lou Diamond Phillips, Peter Facinelli, Robin Tunney, and Wilson Cruz
As Reviewed by James Brundage
When near objects of immense gravity such as black holes, it is said that all things bend. Perhaps it is only fitting that a movie such as Supernova, which poses as sci-fi / mystery / horror and that takes place near an object of large gravity, should have the plot twists bent. Common sense tells us that if you bend something that is already bent it will either become more bent or straighten out. Supernova's plot twists straight out, and the result is something completely by the books.
Supernova is the story about a rescue vessel sent into deep space to pick someone up from a rogue moon. To make a short story shorter, they find both the person (who is, of course, accompanied with creepy music) and an alien artifact capable of creating new matter. Every person who touches the stuff becomes endowed with superhuman strength.
It only takes the discerning viewer a few seconds to figure all this out.
Since the creepy guy the crew picked up from the planet has touched the thing, and since he is obviously the bad guy, the rest of the crew spends all of their time trying to stop him.
That's about it. I have eliminated your need to see it.
Supernova is so absolutely traditional that it voyages into the realm of idiocy. It is as if someone had taken the morons guide to sci-fi and used it to create a film, step by step, with no originality.
The cast is remarkably top-notch for the occasion. Angela Bassett, James Spader, Robert Forster, Robin Tunney, and Lou Diamond Phillips help comprise the cast of what amounts to a very bad movie. If they had all combined their talent, rewrote the script, and filmed it themselves they could have done better.
As proof of how much this film is terrible, even the director didn't want it on him. Although the director is credited as Thomas Lee, he is actually Walter Hill of 48 Hours and Last Man Standing. Any time a director tries to conceal the fact that they made the picture, it is bad news, and Supernova is proof of this thesis.
The last really, really cheesy sci-fi horror about a rescue vessel, Event Horizon had some Latin in it: liberte tutu meus ex inferni. The translation of this is "Save yourself from Hell." Save yourself from Supernova… it's a step in the right direction.

Before Designing a DB
- Context
- Functional requirements
- Non functional requirements
Why is good DB design important?
What is Architecture?
Somewhat hard to define
Can only be defined in an implicit way
Software architecture is the set of design decisions which, if made incorrectly, may cause your project to be canceled. (Eoin Woods)
Architecture is about the important stuff. Whatever that is. (Martin Fowler)
Problem of Architecture:
Many times it is not obvious what are architectural decisions
(because it is only defined implicitly in the context of a project)
Sometimes it only becomes clear in hindsight
Domain-Driven Design
Domain-Driven Design is an approach to the development of complex software in which we:
Domain-Driven Design
Shortened from: https://domainlanguage.com/ddd/patterns/DDD_Reference_2011-01-31.pdf
- domain: A sphere of knowledge, influence, or activity. Application of a program is the domain of the software.
- model: A system of abstractions that describes selected aspects of a domain.
- ubiquitous language: A language structured around the domain model and used by all team members within a bounded context.
- context: The setting in which a word or statement appears that determines its meaning.
Statements about a model can only be understood in a context.
- bounded context: A description of a subsystem, or the work of a particular
team within which a particular model is defined and applicable.
Ubiquitous Language
- common language for all share-holders
- not only a class- or ER-diagram (because this only speaks to technical people)
- clearly defines the language and you should stick to
- a change in language warrants a change in the model


In this project, you’ll connect Redux to a React application. You’’ll configure a Redux store, create Redux reducers and action creators, and use them in a Grocery Store application to add produce to a shopping cart. You’ll also learn how to normalize data in a Redux store.
When you have finished today’s project, your application should have the following features:
Clone the starter repository at [INSERT REPO HERE].
Run npm install
then npm start
to start the
development server.
Navigate to http://localhost:3000. You should see the text “Grocery Store”. If you click on the “Checkout” button in the navigation bar, it should open a side menu. Right now, there are no produce listed so you cannot add items to the shopping cart yet.
The Cart
, ProduceList
and
ProduceDetails
are the components you need to connect to the
Redux store. Take a look at the code there to familiarize yourself with
it.
The src/mockData/produce.json
is the mock data that you will
use to populate the Redux store with. The file has a JSON array of
objects. Each object has the following structure:
{
id: ID,
name: String,
liked: Boolean
}
In your preview of the code, make sure to get understand how the components are all connected (parent-child relationships of all the components, the component tree).
npm install
the following dependencies:
redux
- the Redux packagereact-redux
- for connecting Redux to Reactnpm install -D
the following dev-dependencies:
redux-logger
- a debugging tool for logging all actions
dispatched
First thing you need to do is set up and configure the Redux store.
Create a file called index.js
in a folder called
store
under src
. In this file, you will define
the root reducer and a function that will return a Redux store.
Import createStore
, combineReducers
,
applyMiddleware
, and compose
from `redux.
// ./src/store/index.js
import { createStore, combineReducers, applyMiddleware, compose } from "redux";
createStore
- creates a Redux storecombineReducers
- creates one reducer from multiple
reducers as slices of state
applyMiddleware
- a store enhancer that will allow you to
attach middlewares (a middleware is a function called before any action
hits the root reducer)
compose
- another store enhancer that will allow you to use
more than one store enhancer
Next, define the rootReducer
which will be the root reducer
for the Redux store. The rootReducer
will just be the return
of combineReducers
invoked with an empty object for now.
Now, you are going to create a store enhancer that will be set only when
your application is in development. When in development, you want to add
the redux-logger
middleware and the Redux dev tools extension
store enhancer to your store. For redux-logger
, you will use
the applyMiddleware
which returns a store enhancer. The store
enhancer for the Redux dev tools extension is set by the extension to a
global property, window.__REDUX_DEVTOOLS_EXTENSION_COMPOSE__
.
This store enhancer combines other store enhancers into one, just like
compose
from redux
does.
Set the enhancer
variable when in development to use these
enhancers like so:
// ./src/store/index.js
// ...
let enhancer;
if (process.env.NODE_ENV !== "production") {
const logger = require("redux-logger").default;
const composeEnhancers =
window.__REDUX_DEVTOOLS_EXTENSION_COMPOSE__ || compose;
enhancer = composeEnhancers(applyMiddleware(logger));
}
Let’s break this down.
The logger
variable is set to the default
export
of the imported redux-logger
package using
require
instead of ES6 module imports. Why? ES6 module
imports need to be defined at the very top of the file in the outermost
scope and will be loaded in all node environments. However,
redux-logger
is a development dependency and cannot be loaded
in production. Loading it with require
is needed if you only
want it in a certain node environment.
The composeEnhancers
variable is set to the Redux dev tools
extension’s store enhancer,
window.__REDUX_DEVTOOLS_EXTENSION_COMPOSE__
or the
compose
function from redux
if the extension
fails to load or if you don’t have the extension installed in your
browser.
The Redux’s compose
function takes in store enhancers as its
arguments and combines them to create a single store enhancer. The only
other store enhancer that you need is the
applyMiddleware
invoked with the loaded logger
enhancer
is set to the combined store enhancer.
Finally, define a function called configureStore
that will
take in a preloadedState
and return the result of
createStore
invoked with the rootReducer
, the
preloadedState
, and the enhancer
. Export the
configureStore
function as the default export.
// ./src/store/index.js
// ...
const configureStore = (preloadedState) => {
return createStore(rootReducer, preloadedState, enhancer);
};
export default configureStore;
Now, you need to wrap the React application with the Redux store provider.
Import the configureStore
function into the entry file,
src/index.js
. Import the Provider
component from
react-redux
.
Initialize a variable called store
and set it to the return
of configureStore
(a preloadedState
does not
need to be passed in, it can be undefined
).
In the Root
function component, wrap the
BrowserRouter
component with the
Provider
component. Pass the prop of store
with
the value of store
into the Provider
.
Your entry file should look like this:
// ./src/index.js
import React from "react";
import ReactDOM from "react-dom";
import { BrowserRouter } from "react-router-dom";
import { Provider } from "react-redux";
import configureStore from "./store";
import "./index.css";
import App from "./App";
const store = configureStore();
function Root() {
return (
<Provider store={store}>
<BrowserRouter>
<App />
</BrowserRouter>
</Provider>
);
}
ReactDOM.render(
<React.StrictMode>
<Root />
</React.StrictMode>,
document.getElementById("root")
);
Let’s test your setup!
Navigate to http://localhost:3000 and
open up the browser’s dev tools. In the console, you should see a message
about an invalid reducer. That’s because the
rootReducer
isn’t combining any reducers yet. Ignore this
warning for now.
Open the “Redux” tab in your browser’s dev tools. You should not see the message “No store found”.
In your entry file, expose the store
variable on the
window
only in development for testing
purposes.
Navigate to http://localhost:3000 and
refresh. You should see the store
on the
window
in your browser’s dev tools console. If you call
store.getState()
then you should just get back an empty
object.
If you are having issues while testing, check your syntax in your store and entry files.
Commit your setup code!
To display a list of produce, you need to first store the list of produce in the Redux store. Then you need to extract the produce from the store for display in a React component.
First, you need to create space in the Redux store for the produce. To do this, you will add a key in the Redux store for handling the produce information. This key will be the produce slice of state.
In your store file, src/store/index.js
, add a key of
produce
to the rootReducer
with the value of
produceReducer
:
The produceReducer
is responsible for handling the produce
information in the store, or the produce slice of state.
Now, you need to define the produceReducer
. Create a file in
the store
folder called produce.js
. Define a
function called produceReducer
with state
and
action
as parameters. The state
should default
to an empty object. Add a switch/case
statement on
action.type
inside of the function and return the state as
the default
case. Export the produceReducer
as
default.
// ./src/store/produce.js
export default function produceReducer(state = {}, action) {
switch (action.type) {
default:
return state;
}
}
This is the structure of how all reducer functions should look like by
convention. The reducer should return the old state or a new state
depending on the type
of the action
that gets
dispatched. The state
does not have to be an object. It could
be an array, boolean, etc.
The produce slice of state should be an object with produce id’s as keys. The values should be objects of produce information.
Import the produceReducer
into the store file,
store/index.js
.
Now, test the reducer by refreshing at
http://localhost:3000. The state in
the Redux dev tools extension should show a key of
produce
with the value of an empty object! Also, if you call
store.getState()
in the console, you’ll get an object with a
key of produce with an empty object as the value.
You will use the mock data in the
src/mockData/produce.json
file to add produce to the produce
slice of state. To populate the produce slice of state, you need to
trigger a change to the Redux store state. This can only be done by
dispatching an action.
In the store/produce.js
file, create and export an action
creator called populateProduce
. This function should return
an object with a unique type
key. Create a constant called
POPULATE
and set it to a string literal of
produce/POPULATE
. Set the key of type
in the
return of populateProduce
to this constant.
Import the produce.json
as produceData
. Set a
key of produce
in the return of
populateProduce
to produceData
. The key of
produce
is a payload key.
If you try dispatching the populateProduce
action right now,
the Redux store state will not change. Whenever you create a new action
type, you need to add a case for it in reducer that handles the slice of
state that needs to be updated.
In the produceReducer
add a case for the
action.type
of POPULATE
. This case should turn
the action.produce
array into an object and return the
object. action.produce
is an array of produce data objects.
The object returned should have keys set to the id’s of the produce data
objects with their values as the respective produce data objects.
The action.produce
array should look something like this:
[
{ id: 1, name: "Longos - Greek Salad", liked: false },
{ id: 2, name: "Juice - Lagoon Mango", liked: false },
{ id: 3, name: "Lamb - Whole, Frozen", liked: false },
// ...
];
The object created from the array should look something like this:
{
1: { id: 1, name: "Longos - Greek Salad", liked: false },
2: { id: 2, name: "Juice - Lagoon Mango", liked: false },
3: { id: 3, name: "Lamb - Whole, Frozen", liked: false },
// ...
}
Try attempting this before looking below.
// ./src/store/produce.js
import produceData from "../mockData/produce.json";
const POPULATE = "produce/POPULATE";
export const populateProduce = () => {
return {
type: POPULATE,
produce: produceData,
};
};
export default function produceReducer(state = {}, action) {
switch (action.type) {
case POPULATE:
const newState = {};
action.produce.forEach((produce) => {
newState[produce.id] = produce;
});
return newState;
default:
return state;
}
}
This conversion from an array into this object structure is known as normalizing data. It’s faster to search for a produce by its id in this object structure than in an array. Normalizing data is a common practice even outside of Redux, so practice getting comfortable with it!
populateProduce
action
To test the populateProduce
action, import it into the entry
file and attach it to the window
just like you did with the
store
.
// ./src/index.js
// ...
import { populateProduce } from "./store/produce";
// ...
if (process.env.NODE_ENV !== "production") {
window.store = store;
window.populateProduce = populateProduce;
}
Go to http://localhost:3000 and use
store.dispatch
on the browser’s dev tools console to dispatch
the action from the populateProduce
action creator on the
window
.
As a response to dispatching this action, the
redux-logger
middleware should aesthetically display the
previous state, action, and the next state in the console. The Redux dev
tools extension should now show the action dispatched and the changed
state.
The new state should look something like this:
{
produce: {
1: { id: 1, name: "Longos - Greek Salad", liked: false },
2: { id: 2, name: "Juice - Lagoon Mango", liked: false },
3: { id: 3, name: "Lamb - Whole, Frozen", liked: false },
// ...
}
}
To debug the action, you can add console.log
’s and/or
debugger
’s in the action creator and reducer. To hit them,
try refreshing and dispatching the action in the console again.
Even if your state looks the way you expect it to look, try adding
console.log
and/or debugger
into the action
creator and reducer to examine how and when they are invoked.
populateProduce
To programmatically dispatch the populateProduce
action
instead of doing it through the browser console, you will dispatch this
action when the App
component gets loaded.
To get the dispatch
method in a React component, import and
use the useDispatch
hook from react-redux
in the
App
component.
Import the populateProduce
action creator into the
App
component file.
Use the useEffect
hook to dispatch the action when the
App
component first loads.
Your App
component should look something like this:
// ./src/App.js
// ...
import { useDispatch } from "react-redux";
import { populateProduce } from "./store/produce";
function App() {
const dispatch = useDispatch();
useEffect(() => {
dispatch(populateProduce());
}, []);
// ...
}
Reload http://localhost:3000. You should see the Redux store state updated automatically with the populate produce action!
You may have noticed a warning in the React server logs or in the
browser’s console. “React Hook useEffect has a missing dependency:
‘dispatch’.” Add dispatch
into useEffect
’s
dependency array. The dispatch
function should never change
across re-renders so useEffect
should only dispatch the
action once.
So far, you added the produce mock data into the Redux store state. But
this didn’t change anything on your actual React application. To display
the produce, you need the ProduceList
component to access the
produce slice of state from the Redux store.
In the ProduceList
component file, import
useSelector
from react-redux
.
useSelector
accepts a function as a parameter.
useSelector
will pass the updated state into the function
whenever the state gets updated. The return value of the function will be
the return of the useSelector
function. In the component, set
the produce
variable to the return of
useSelector
and pass in a function that will return the
produce
slice of state from the updated state.
The ProduceList
component will turn the products into an
array of ProduceDetails
components to be rendered.
If you refresh the http://localhost:3000 now, the produce should be displayed under “All Produce”!
Commit your code!
When the “Checkout” button in the navigation bar is clicked, the side bar containing the shopping cart should open. Let’s try adding produce to the shopping cart.
The shopping cart is a separate entity from the produce list. The shopping
cart needs to know which produce and how much of it was added to the cart.
You need a cart slice of state that will hold an object with produce id’s
as its keys and objects with a count
property as its values.
Create a cart.js
file in src/store
and define
and export a cartReducer
from this file. Add the
cart
slice of state with this as the reducer in the store
file (src/store/index.js
). Use the
produceReducer
as an example if you get stuck. Test the
reducer in the same way as the way you tested the
produceReducer
.
The store state should now look something like this:
Create the necessary Redux entities for adding produce to the cart.
The Redux store state should look something like this when a produce with an id of 3 is added.
Define an action creator for adding an item with a specified id to the
cart. The action creator should have the produce’s id
as the
parameter and should return it as a payload key.
In the reducer, add a case for the action type of adding an item with the
id in the action payload. The state returned should be a new object that
includes all the keys of the previous state plus with the desired item id
as a new key. The value of that key should be an object with properties of
id
and count
(set to 1).
Hint: To create a new object that includes all the keys of another object with additional keys:
Test the action creator in the same way that you tested the
populateProduce
action.
In the ProduceList
component, all the produce in the Redux
store is mapped to a array of ProduceDetails
components. The
ProduceDetails
component has a button element with a
className
of “plus-button”. When that button is clicked,
dispatch the add to cart action with the id of the produce in that
component.
Test this out by navigating to http://localhost:3000 and clicking the plus button on any of the produce in the list. Check to see if the new Redux store state has that produce in the cart slice of state.
Note: If you open the cart by clicking the “Checkout” button right now, you will not see the produce that you added in there. That’s because you didn’t connect the cart to read the cart slice of state yet.
Display the produce in the cart slice of state in the cart side bar.
The Cart
component renders the list of items in the cart side
bar. Set the cart
variable to the extracted cart slice of
state in the Redux store state (take a look at the
ProduceList
component to refresh yourself on how to access
information from the Redux store).
If you refresh http://localhost:3000 and add a produce to the cart, you should see something in the cart now!
There is something in the cart, but the item can’t be identified. The name
of the produce should be displayed next to the count. The
name
of the produce is stored in the
produce
slice of state, but the Cart
component
only has the cart
slice of state. Extract the
produce
from the state and set it to the
produce
variable.
The cartItems
array should return an array of produce items
with information combined from both the cart and the produce slices of
state.
Now if you refresh the page, you should see the cart items with names!
This is a good time to commit! Every time you finish a phase, or a chunk of working code, commit!
Add the functionality to remove produce from the cart when the “Remove” button is clicked.
When the plus button next to a cart item is clicked, increment the count of the cart item by 1. When the minus button next to a cart item is clicked, decrement the count of the cart item by 1.
When the number in the input field next to a cart item is changed and clicked off of, it should update the count for that cart item in the Redux store state.
If clicking the minus button or changing the number in the input field ever updates to a count lower than 1, remove the cart item.
When the plus button next to a produce in the produce list is clicked, the item should be added to the cart if it’s not in the cart. If it is already in the cart, increment the count of the respective cart item by 1.
When the “Purchase” button is clicked in the cart, it should empty the cart.
When the like button next to a produce in the produce list is clicked,
then the boolean of liked
on the produce in the Redux store
produce slice of state should be toggled to
true
/false
.
Instead of creating a different selector function every time you use the
hook, useSelector
, for the same purpose (e.g. extracting the
produce
slice of state), you can define a single function to
be used anytime you need the same information from the Redux store state.
For example, to get an array of all the produce in the Redux store state,
you can use the following selector function in the
src/store/produce.js
file:
Import this function into the ProduceList
component and
remove the following lines:
Replace it with this line:
This may seem like it’s much more work than just defining the selector function inside the component, but it will save you the time from having to refactor all your code in all the components if you change the structure of your state. Instead, you can just refactor the one file that holds all your Redux actions, reducer, and selector functions.
You don’t need to use selector functions. It’s up to you whether or not you want to use them.
Practice defining your own selector functions by refactoring the code to use selector functions only.
Note: For the Cart
component, try making a single selector
function that will extract the cart items with the cart and produce
information (including the name
).
Reconfigure your cart reducer to maintain the order of the added produce to the cart. For example, if you add produce with an id of 3 then produce with an id of 1 to the shopping cart, the produce with the id of 3 should come before the produce with the id of 1 in the shopping cart.
Hint: Store an object and an array in your cart slice of state. If you did the selector functions correctly, you only need to update the Redux files. No need to change any of the React components.
For an added bonus, try to configure the application to open the cart side bar whenever there is a new item added to the cart.


WIDE AWAKE Reviewed by Harvey Karten, Ph.D. Miramax Films Director: M. Night Shyamalan Writer: M. Night Shyamalan Cast: Denis Leary, Dana Delany, Rosie O'Donnell, Robert Loggia, Joseph Cross
The ad for "Wide Awake" notes, "First kisses. Outrageous pranks. A teacher with a killer fastball. To survive this year, Joshua Beal will have to stay wide awake." Don't be fooled. There is quite a bit of drama in the film but most of it is internal. One of the teachers may indeed have had a killer fastball, and if two lips touched, the intimacy happened so quickly that no one in the audience saw it. The pranks in "Animal House" might have been outrageous but the most abominable undiscipline here is a tie between a kid who rides a mop and pail through the halls of the Catholic grammar school and another who takes a picture of the Pope out in the rain.
"Wide Awake," unlike other coming-of-age stories, is not about a kid's fears of not fitting in or not getting a date or of needing to escape from abusive parents or an intolerable school. It deals with a ten-year-old's search for God, no less, and the principal suspense it generates is, "Does he or does he not find Him?" Suspense, however, is no more writer- director M. Night Shyamalan's concern than is physical action, and the only resemblance to disease-of-the-week activity is one young man's suffering an epileptic fit, a contrived gesture that does nonetheless serve to put the central figure in touch with the fragility of human existence at all ages.
Ten-year-olds, however gifted, do not often spend much time pondering metaphysical issues. What prompts the adorable Joshua Beal's search for God at such a young age is his closeness with his grandfather, a man who had recently died of bone marrow cancer and who enjoyed a few heart- tugging scenes with his grandson that made his condition all too identifiable. At one point in Joshua's memory the aging Grandpa Beal (Robert Loggia) is in church with Joshua (Joseph Cross), allowing the little one to play with his face, when the priest calls for all sick members of the congregation to step up to the pulpit to receive wafers. At another time, Joshua is competing with his classmates in a hundred-yard dash, falls down, and observes his grandpa at the finish line prodding him to get up and finish the event--as if to say that this would be the last time the two would enjoy an athletic event together.
"Wide Awake" takes a few obligatory pokes at the nuns, but this is no diatribe from the pen of a Christopher Durang. The ladies in habits do not physically abuse their charges, save in one case in which a kid is dragged back to the classroom by his ears.  Rosie O'Donnell as Sister Terry tries to get her class involved in Jesus' problems by situating him on a blackboard behind the pitchers' mound hurling the sphere toward Judas at the plate.   Joshua's introduction to romance is a fleeting one, but one in which he observes himself getting "a biological reaction" when a pretty girl flirts with him and offers him a rose.
Writer M. Night Shyamalan, whose first movie feature "Praying with Anger," is about an East Indian living in the U.S. and making his first trip to India, must have decided he did not want a G rating, so he threw in the "s" word four times-- which shouldn't bother anyone. It's good to see a heartwarming film so well realized that deals not with the estrangement between generations but with the natural love that the old and young can share. Rated PG. Running Time: 90 minutes. (C) 1998 Harvey Karten

Once a protest fortress, Hong Kong campus quiet now after elections
There has been a rare break in the violence in recent days as protesters, anxious to validate their cause through the ballot box, hit the pause button to ensure the polls won’t be postponed.
25 Nov 2019, 04:57
Overturned chairs. Empty plastic bottles scattered around. Food leftovers rotting in the canteen. Most of the protesters who took over the Hong Kong Polytechnic University have left following clashes with police, but an unknown number have remained inside, hoping somehow to avoid arrest. (AP)
Six masked protesters surrendered before dawn Friday, bringing to about 30 the number that have come out the previous day from the campus surrounded by police. (AP)
Tang Chun-Keung, head of the Hong Kong Association of the Heads of Secondary Schools, told AP that the holdouts include minors, numbering less than 10, and they are emotionally unstable. Tang entered the campus Friday with some others but failed to find them. (AP)
Police Commissioner Tang Ping-keung said that those under 18 can leave, although they may face charges later, and pledged impartial treatment for all adults facing arrest. (AP)

Voting was underway Sunday in Hong Kong elections that have become a barometer of public support for anti-government protests now in their sixth month. Long lines formed outside polling stations for 452 seats in the city’s 18 district councils. The councils are largely advisory and have little power. But the election has taken on symbolic importance in the semiautonomous Chinese territory. (AP)

VALUES
Section: SQL Commands (7)Updated: 2012-08-14
Index Return to Main Contents
NAME
VALUES - compute a set of rowsSYNOPSIS
VALUES ( expression [, ...] ) [, ...] [ ORDER BY sort_expression [ ASC | DESC | USING operator ] [, ...] ] [ LIMIT { count | ALL } ] [ OFFSET start [ ROW | ROWS ] ] [ FETCH { FIRST | NEXT } [ count ] { ROW | ROWS } ONLY ]
DESCRIPTION
VALUES computes a row value or set of row values specified by value expressions. It is most commonly used to generate a ``constant table'' within a larger command, but it can be used on its own.
When more than one row is specified, all the rows must have the same number of elements. The data types of the resulting table's columns are determined by combining the explicit or inferred types of the expressions appearing in that column, using the same rules as for UNION (see in the documentation).
Within larger commands, VALUES is syntactically allowed anywhere that SELECT is. Because it is treated like a SELECT by the grammar, it is possible to use the ORDER BY, LIMIT (or equivalently FETCH FIRST), and OFFSET clauses with a VALUES command.
PARAMETERS
- expression
- A constant or expression to compute and insert at the indicated place in the resulting table (set of rows). In a VALUES list appearing at the top level of an INSERT, an expression can be replaced by DEFAULT to indicate that the destination column's default value should be inserted. DEFAULT cannot be used when VALUES appears in other contexts.
- sort_expression
- An expression or integer constant indicating how to sort the result rows. This expression can refer to the columns of the VALUES result as column1, column2, etc. For more details see ORDER BY Clause [select(7)].
- operator
- A sorting operator. For details see ORDER BY Clause [select(7)].
- count
- The maximum number of rows to return. For details see LIMIT Clause [select(7)].
- start
- The number of rows to skip before starting to return rows. For details see LIMIT Clause [select(7)].
NOTES
VALUES lists with very large numbers of rows should be avoided, as you might encounter out-of-memory failures or poor performance. VALUES appearing within INSERT is a special case (because the desired column types are known from the INSERT's target table, and need not be inferred by scanning the VALUES list), so it can handle larger lists than are practical in other contexts.
EXAMPLES
A bare VALUES command:
VALUES (1, 'one'), (2, 'two'), (3, 'three');This will return a table of two columns and three rows.  The most common use is in INSERT:
INSERT INTO films (code, title, did, date_prod, kind) VALUES ('T_601', 'Yojimbo', 106, '1961-06-16', 'Drama');
In the context of INSERT, entries of a VALUES list can be DEFAULT to indicate that the column default should be used here instead of specifying a value:
INSERT INTO films VALUES ('UA502', 'Bananas', 105, DEFAULT, 'Comedy', '82 minutes'), ('T_601', 'Yojimbo', 106, DEFAULT, 'Drama', DEFAULT);
VALUES can also be used where a sub-SELECT might be written, for example in a FROM clause:
SELECT f.* FROM films f, (VALUES('MGM', 'Horror'), ('UA', 'Sci-Fi')) AS t (studio, kind) WHERE f.studio = t.studio AND f.kind = t.kind; UPDATE employees SET salary = salary * v.increase FROM (VALUES(1, 200000, 1.2), (2, 400000, 1.4)) AS v (depno, target, increase) WHERE employees.depno = v.depno AND employees.sales >= v.target;Note that an AS clause is required when VALUES is used in a FROM clause, just as is true for SELECT. It is not required that the AS clause specify names for all the columns, but it's good practice to do so. (The default column names for VALUES are column1, column2, etc in PostgreSQL, but these names might be different in other database systems.)
When VALUES is used in INSERT, the values are all automatically coerced to the data type of the corresponding destination column. When it's used in other contexts, it might be necessary to specify the correct data type. If the entries are all quoted literal constants, coercing the first is sufficient to determine the assumed type for all:
SELECT * FROM machines WHERE ip_address IN (VALUES('<IP_ADDRESS>'::inet), ('<IP_ADDRESS>'), ('<IP_ADDRESS>'));
- Tip: For simple IN tests, it's better to rely on the list-of-scalars form of IN than to write a VALUES query as shown above. The list of scalars method requires less writing and is often more efficient.
COMPATIBILITY
VALUES conforms to the SQL standard. LIMIT and OFFSET are PostgreSQL extensions; see also under SELECT [select(7)].
