Lightning Web Components Developer Guide. Chapter 3: Communication between Lightning Web Components
Here is our third article in the series on LWC. In the previous two, we delved into the principles of building and using components, as well as the basic tenets of markup and its features in LWC. In this article, we will explore communication between LWC components, so let's get started.
As a Lightning web component (LWC) developer, you may need to transfer data between components in cases where components are parent-child or unrelated. In this article, we will look at three ways to transfer data between LWC components:
 - Using the "@api" annotation.
 - Using dispatch event.
 - Using the Lightning message channel message service.
So let's go!
"@api" Annotation Properties
Let's take a look at the "@api" annotation. This annotation is used to define public properties and methods in a component that can be accessed by other components. This is especially useful when transferring data between parent and child components. We can define a public property in the child component using the "@api" annotation and set its value in the parent component. For example, we can define a public property in the child component as follows.
import { LightningElement, api } from 'lwc';
export default class ChildComponent extends LightningElement {
 @api message;
}
In the parent component, we can set the value of the 'message' property for the child component as follows:
<template>
 <c-child-component message="Hello World"></c-child-component>
</template>
In this example, we pass the 'Hello World' value from the parent component to the child component using the '@api' annotation.
Let's also consider the use of '@api' with functions. They allow invoking specific functionality of a component from outside, from other components or templates. This is a powerful tool for communication between components and exchanging data and actions.
You can declare a method in your LWC component and annotate it with '@api'. This allows the method to become public and accessible for invocation from other components.
import { LightningElement, api } from 'lwc';
export default class MyComponent extends LightningElement {
 @api
 myMethod(param) {
 console.log('Received parameter:', param);
 }
}
In another LWC component, you can reference the component containing a method annotated with "@api" and call that method.
<template>
 <c-my-component></c-my-component>
 <lightning-button label="Call Method" onclick={callMethod}></lightning-button>
</template>
import { LightningElement } from 'lwc';
export default class AnotherComponent extends LightningElement {
 callMethod() {
 const myComponent = this.template.querySelector('c-my-component');
 if (myComponent) {
 myComponent.myMethod('Hello from AnotherComponent');
 }
 }
}
In the example provided above, when the button is pressed on the parent component, the child component receives a specific text as a parameter and outputs it to the console.
The use of "@api" allows you to publicly export the functionality of your component and facilitate interaction with other components. Remember that adhering to security practices and robust design is crucial for effective communication between components.
Dispatch Event
Another way of communication between components is through dispatch events, which are used to transmit data between components that are not necessarily related. They can be used for data exchange between parent and child components, sibling components, or even components that do not belong to the same hierarchy.
Let's consider an example of a simple form where the user enters some data and clicks the 'Submit' button.
We can create a special event in the form component triggered when the user clicks the 'Submit' button. The event can contain the data entered by the user, which can then be passed to another component for further processing. Here is how we can create a special event in the form component:
import { LightningElement } from 'lwc';
export default class FormComponent extends LightningElement {
 handleSubmit() {
 const data = {
 name: this.template.querySelector('input[name="name"]').value,
 email: this.template.querySelector('input[name="email"]').value
 };

 const event = new CustomEvent('submitform', {
 detail: data
 });

 this.dispatchEvent(event);
 }
}
In this example, we create a special event named 'submitform' and pass it to an object containing the user-entered data. Then, we use the dispatchEvent method to trigger the event.
In another component, we can listen for the 'submitform' event and process the received data. Here is how we can listen for the event and handle the data:
import { LightningElement } from 'lwc';
export default class ResultComponent extends LightningElement {
 connectedCallback() {
 this.addEventListener('submitform', this.handleFormSubmit.bind(this));
 }
 handleFormSubmit(event) {
 const data = event.detail;
 console.log('Name: ${data.name}, Email: ${data.email}');
 }
}
In this example, we use the addEventListener method to listen for the 'submitform' event. When the event is triggered, the 'handleFormSubmit' method is called, and we retrieve the data passed in the event using the 'detail' property. This approach is useful when components do not belong to the same hierarchy.
Another way to handle events is by using the 'on' directive in the HTML file where the child component is invoked.
To capture this event in the parent component using the 'on' directive, you can do the following:
 - In the HTML file of the parent component, add the child component and include the 'on' directive:
<template>
 <div>
 <c-my-child-component onsubmitform={handleFormSubmit}></c-my-child-component>
 </div>
</template>
 - In the 'on' directive, specify the event name (in this case, onsubmitform) and the name of the function that will handle the event (in this case, handleFormSubmit). In the JavaScript file of the parent component, define the handleFormSubmit function:
handleFormSubmit(event) {
 const data = event.detail;
 console.log('Name: ${data.name}, Email: ${data.email}');
}
 - In the handleFormSubmit function, you can access the event properties and perform any necessary actions based on the data in the event.
Note that when using the 'on' directive, the event handling function must be defined in the JavaScript file of the parent component.
One of the advantages of using the 'on' directive is that it allows you to handle events more declaratively. By including the 'on' directive in the HTML file, you can see which events are being handled and which functions handle them, making code understanding and maintenance easier.
However, using the 'on' directive can also make the code less flexible. If you need to handle the same event in multiple components, you will need to define the event-handling function in the JavaScript file for each element. Conversely, if you use event listeners in the JavaScript file of the parent component, you can define the event handling function once and reuse it in multiple components.
In general, both approaches have their advantages and drawbacks, and the choice between them depends on the specific requirements of your project.
Let's also discuss the use of the "bubbles" and "composed" parameters in our dispatchEvent.
Bubbles
The 'bubbles' parameter is used when dispatching events in Lightning (LWC) to control whether the event 'bubbles' through the DOM hierarchy. Event bubbling is a mechanism where, after processing an event on a specific element, it then propagates up to parent elements for possible further handling.
In LWC, events typically bubble by default, similar to standard browser events. This means that if you dispatch an event from a child component, it will travel up through the hierarchy of parent components, allowing higher-level components to listen for the event and respond to it if they choose to do so. This natural event propagation can simplify the communication between components, enabling a parent component to respond to actions taken by its child components.
Lightning Web Components Developer Guide
Composed
The 'composed' parameter is another attribute used when dispatching events in LWC, and it determines whether the event can cross the boundary of the shadow DOM. Shadow DOM is a fundamental concept in web components that encapsulates a component's styles, structure, and functionality.
If the 'composed' parameter is set to true when dispatching an event, then this event can leave the boundaries of the shadow DOM and be processed by elements outside it. This can be useful if you want to communicate between components that are not directly related through the component hierarchy. However, setting the 'composed


A general framework for formulating structured variable selection
Published: 25 Jan 2024, Last Modified: 17 Sept 2024Accepted by TMLREveryoneRevisionsBibTeXCC BY 4.0
Abstract: In variable selection, a selection rule that prescribes the permissible sets of selected variables (called a "selection dictionary") is desirable due to the inherent structural constraints among the candidate variables. Such selection rules can be complex in real-world data analyses, and failing to incorporate such restrictions could not only compromise the interpretability of the model but also lead to decreased prediction accuracy. However, no general framework has been proposed to formalize selection rules and their applications, which poses a significant challenge for practitioners seeking to integrate these rules into their analyses. In this work, we establish a framework for structured variable selection that can incorporate universal structural constraints. We develop a mathematical language for constructing arbitrary selection rules, where the selection dictionary is formally defined. We demonstrate that all selection rules can be expressed as combinations of operations on constructs, facilitating the identification of the corresponding selection dictionary. We use a detailed and complex example to illustrate the developed framework. Once this selection dictionary is derived, practitioners can apply their own user-defined criteria to select the optimal model. Additionally, our framework enhances existing penalized regression methods for variable selection by providing guidance on how to appropriately group variables to achieve the desired selection rule. Furthermore, our innovative framework opens the door to establishing new $\ell_0$-based penalized regression techniques that can be tailored to respect arbitrary selection rules, thereby expanding the possibilities for more robust and tailored model development.

Lakefront Lighting Replacement
The City of Kenosha retained Clark Dietz for the investigation of the current condition and integrity of their promenade lighting along Kenosha's lakefront in Harbor Park and to provide Electrical Lighting Design Services. Clark Dietz was tasked to identify the most economical strategy to upgrade this lighting system along the lakefront pathway. The existing lighting limits are from 50th Street and 6th Avenue to 61st Street and 3rd Avenue and consisted of 130 poles along this route. The initial objective was to reuse the existing poles, bases & wiring and to just investigate refurbishing and re-lamping of the poles using current technology.
Lighting Condition Analysis
Clark Dietz provided a visual assessment of the existing pathway lighting conditions including lighting foundations, light poles and luminaires. Additionally, we interviewed City electrical staff to determine what issues they were aware of when repairs were made. With the help of City staff, we assessed the existing wiring and grounding connections, we traced out the electrical circuitry to each pole to determine which lighting cabinet the lights belonged to, and finally measured the loads that were present on each circuit as well as the overall loads on each cabinet. Based on our investigation, we were able to determine if foundations, light poles, and existing wiring could simply be reused. If possible, existing poles in good condition could be refurbished. Clark Dietz coordinated with blast shops on costs and timeline for refinishing and painting. If any poles were in need of replacement due to condition, new poles were required to match the existing style.
After the preliminary investigations and assessments, we determined that the existing infrastructure was in poor condition. The following was concluded:
- Concrete bases severely deteriorated with corroded reinforcing bars;
- Circuit wiring was direct buried and had many splices;
- Existing steel poles were corroded at the base and luminaire arms;
- Many decorative base plates were either missing or broken, and
- Voltage drop requirements were not met using existing wiring
This assessment concluded that reusing and/or refurbishing of the existing lighting system was not economical and a new lighting system should be pursued.
After careful assessment and determining a replacement fixture, Clark Dietz provided lighting design using AGi-32 to coincide with the existing pole base locations to determine what the most optimized photometrics could be for the existing light pole spacing. We analyzed and compared the proper illumination in accordance with IES Standards for urban roadways. The lighting design included:
- Contacting Diggers Hotline for underground survey locates.
- Analyzing existing photometrics using light meters in order to provide comparisons with the new fixtures.
- Providing plan sheets using mostly Aerial photography with supplemental survey.
- We designed the proposed lighting using similar fixtures that were currently in place.
- Showing lighting items and limits.
- Showing all connections for power either to an existing cabinet or a proposed cabinet (coordination with city of Kenosha).
- Providing detail sheets
- Surveying utilities and lakefront pathway.
- Providing voltage drop calculations using existing wire for entire limits of pole replacements or for new wire.
- Providing a staging plan to keep the pathway lit during construction. We coordinated work with the City on the viable options.
- Providing specifications for Bidding
- Providing bid tab of all lighting quantities

Is India Falling into the Malthusian Trap?
April 30, 2008 • News
The connection between Malthus and India are twofold. For one, the country provided the fitting final stage to re-enact his theory on divergent growth pattern between population and foodgrain production even as late as the 1960s, when India was plagued by booming population growth and a diffident growth in food production.
However, there was a more tenuous connection between the economist and Indian economic history. Malthus was the first professional economist by training to teach at the college founded at Haileybury in England by the East India Company to train its young administrators on the rudiments of economic theory.

Walking-in-place techniques for locomotion in virtual environments typically have two problems that impact their usability: system latency (particularly troublesome when starting and stopping locomotion), and the fact that the change in the user's viewpoint may not be smooth and continuous. This paper describes a new WIP interface that improves both latency and the continuity of synthesized locomotion in the virtual environment. By basing the virtual avatar motion on the speed of the user's heel motion while walking in place, we create a direct mapping from foot-motion to locomotion that is responsive, intuitive, and easy to implement. In this paper, we describe the technique, analyze its starting and stopping latency, and provide experimental results on the suppression of false steps and general usability of the system.

Over 200,000 Fish Found Dead in Argentine Lake
Environmental officials have several possible theories about what could have caused this, including insufficient oxygen in the water. That could have led to respiratory dysfunction or water contamination. Another possibility is that some sort of poisonous substance was dumped in the lake.
Because the lake supplies water to several nearby towns, the reservoir's water quality has been tested and the results will be announced in the upcoming days. Lake Ipizca, which attracts about 400 fishermen and water sports fans a week, will remain closed until this mystery has been solved.

This guide will make use of the VoiceMeeter Banana software to split audio for the selective recording feature in Streamlabs OBS. For example, removing alert audio from your recording and allowing it to come through to you and your stream.
This guide builds on top of the Split Audio using VoiceMeeter Banana guide, so if you have not set up VoiceMeeter Banana yet, please follow that guide first to have the starting point for this guide.
Using both virual outputs of VoiceMeeter Banana
In addition to the initial set up, you also will be using the VoiceMeeter Aux Output (VB-Audio VoiceMeeter AUX VAIO), set as the Mic/Auxiliary Device 2. Your microphone can be set in the Mic/Auxiliary Device 3.
Browser Source Audio via OBS
The next thing to do is have audio from browser sources and widgets, such as the Streamlabs Alert box go through the audio system of Streamlabs OBS instead of having the output to the default playback device of Windows, mixing it with any other audio, such as the game audio.
To do this, open the properties of the browser source or widget and check Control Audio via OBS. For widgets, like the Alert Box widget, this is found under the "Source". After this, you would need to monitor these sources in order to hear the audio again, more about this down below!
Set the Audio Monitoring Device
By default, the monitoring device is the same default playback device set in Windows, which would mean if you were to monitor any sources it would be mixed with any other audio and end up on the recording again. Set the Audio Monitoring Device found in the Advanced Settings of Streamlabs OBS to VoiceMeeter Aux Input (VB-Audio VoiceMeeter AUX VAIO). Now, game audio (default desktop) and monitored sources are separated from each other, each to one of the virtual inputs that VoiceMeeter Banana has to offer.
Advanced Audio Settings
Open the Advanced Audio Settings by clicking the ⚙ icon above the Mixer in Streamlabs OBS. In here set the sources that you want to hear and be on stream only to "Monitor Only". Furthermore, you would need to set the audio tracks, where track 1 will be used for the stream and additional tracks will be used for the recording.
In the following configuration the Alert Box is being monitored and the audio is not on the recording or stream. The stream will get the audio from VoiceMeeter Banana virtual output and the microphone (track 1). The recording will get the audio from the VoiceMeeter Banana virtual aux output (track 2), the microphone (track 3), and optionally the stream audio that includes other audio sources again (track 4).
Advanced Output Mode
In order to select which audio tracks you want to use for stream and recording, you would need to use the Advanced Output mode in the Output Settings of Streamlabs OBS. For Streaming select track 1 and under Recording check track; 2, 3, and 4. Make sure the Recording Format you selected supports multi-track recording, such as TS, MKV, or MP4.
Route audio with VoiceMeeter Banana
Back to VoiceMeeter Banana again where you will "patch" the audio from one of the inputs to one of the outputs, Virtual Output B1 is used for the stream and Virtual Aux Output B2 is used for the recording.
VoiceMeeter Banana has now both virtual inputs in use, the main would be the default desktop audio which usually contains game audio and the aux input contains monitored sources audio. The monitoring you want to "patch" only to A1 and B1, your headset and stream where the desktop audio you want to patch to A1, B1, and B2, your headset, the stream and recording.


Your best friend for file transfer.
Fetch application logoFetch
Fetch Icon Fetch Help > Using Fetch > Uploading pictures for eBay
A common use for Fetch is to upload pictures of items you're auctioning on eBay to a web server. Fetch is only part of what you need to accomplish this task—you also need an account with a service that offers web hosting, such as your Internet service provider or a web hosting service. That provider should be able to tell you the hostname, username and password you need to use in Fetch.
Fetch can only help transfer pictures from your Macintosh to a web server; it cannot host pictures for you. Fetch Softworks is not a service provider.
To upload pictures for use on eBay, follow these steps:
 1. Create a digital picture of your item. Use a digital camera, scan the item with a scanner, or take your film to a store that can put your photos on CD.
 2. Choose the New Connection command from the File menu. The New Connection dialog appears:
 1. Enter the hostname of your server, your username, and your password in the appropriate text fields of the New Connection dialog. If you are unsure what to enter here, see the What do I enter in the hostname, username, and password fields? help topic.
 2. Click the Connect button.
 3. You should see a list of the files that make up your website:
 1. A dialog for selecting files appears:
 1. Navigate to the folder on your Macintosh where the picture of your item is stored.
 2. Select it.
 3. Click the Put button to begin the transfer.
 4. Once the file is transfered, you are done using Fetch for now.
 5. Go to eBay in your web browser and fill out the form for listing your item for sale. One of the steps is to enter the web address (URL) for the picture you have just uploaded. The web address (URL) will look something like this:. The web address may be different from the hostname you used to upload the picture. Your service provider can tell you what the correct web address for your picture is. If you think you know it, you can test it by typing it into a new window in your web browser. If your picture appears, you're all set and you can enter that same address into the eBay form.
You can upload multiple pictures and link to them in your item description, in addition to the one you specify when you create the listing.
If you regularly upload pictures to a website for eBay, you may want to set up WebView, which lets you select files in Fetch and click the WebView button to view them in your web browser, and use the Copy Web Address command to copy the web address of those files. See the setting up WebView topic for more information.


Access AddToFavorites Method Example
AddToFavorites Method – the Add To Favorites method adds the name of the current database to the Favorites folder. When applied to a Control object, the AddToFavorites method adds the hyperlink address contained in a control to the Favorites folder.
The Add To Favorites method has the same effect as clicking AddToFavorites on the Favorites menu on the Web toolbar when view a page on the internet.
Here is an example of adding to favorites the hyperlink contained in a control field on a form:
We add our Blue Claw Database Design url to the field called Field1 on the form. This happens when the form loads in the Form Load event. You could also allow the user to type in the hyperlink address or select it from a list.
Private Sub Form_Load()
Me!Field1.HyperlinkAddress = "_URL_
End Sub
Next, we add the link to our favorites list when the user clicks the Field1 hyperlink.
Private Sub Field1_Click()
Me!Field1.Hyperlink.AddToFavorites
End Sub

Assignment to uninitialized local variables also serves as variable declaration. The variables start to exist until the end of the current scope is reached. The lifetime of local variables is determined when Ruby parses the program.
In the above example local variables are id, name and addr.
Ruby Constants:
Constants begin with an uppercase letter. Constants defined within a class or module can be accessed from within that class or module, and those defined outside a class or module can be accessed globally.
Constants may not be defined within methods. Referencing an uninitialized constant produces an error. Making an assignment to a constant that is already initialized produces a warning.
#!/usr/bin/ruby
class Example
 VAR1 = 100
 VAR2 = 200
 def show
 puts "Value of first Constant is #{VAR1}"
 puts "Value of second Constant is #{VAR2}"
 end
end
# Create Objects
object=Example.new()
object.show
Here VAR1 and VAR2 are constant. This will produce the following result:
Value of first Constant is 100
Value of second Constant is 200
Ruby Pseudo-Variables:
They are special variables that have the appearance of local variables but behave like constants. You can not assign any value to these variables.
 - self: The receiver object of the current method.
 - true: Value representing true.
 - false: Value representing false.
 - nil: Value representing undefined.
 - __FILE__: The name of the current source file.
 - __LINE__: The current line number in the source file.

git reset
If git revert is a "safe" way to undo changes, you can think of git reset as thedangerous method. When you undo with git reset(and the commits are no longer referenced by any ref or the reflog), there is no way to retrieve the original copy—it is a permanent undo. Care must be taken when using this tool, as it's one of the only Git commands that has the potential to lose your work.
Like git checkout, git reset is a versatile command with many configurations. It can be used to remove committed snapshots, although it's more often used to undo changes in the staging area and the working directory. In either case, it should only be used to undolocal changes—you should never reset snapshots that have been shared with other developers.
Usage:
git reset <file>
Remove the specified file from the staging area, but leave the working directory unchanged. This unstages a file without overwriting any changes.
git reset
Reset the staging area to match the most recent commit, but leave the working directory unchanged. This unstages all files without overwriting any changes, giving you the opportunity to re-build the staged snapshot from scratch.
git reset --hard
Reset the staging area and the working directory to match the most recent commit. In addition to unstaging changes, the --hard flag tells Git to overwrite all changes in the working directory, too. Put another way: this obliterates all uncommitted changes, so make sure you really want to throw away your local developments before using it.
git reset <commit>
Move the current branch tip backward to <commit>, reset the staging area to match, but leave the working directory alone. All changes made since <commit> will reside in the working directory, which lets you re-commit the project history using cleaner, more atomic snapshots.
git reset --hard <commit>
Move the current branch tip backward to <commit> and reset both the staging area and the working directory to match. This obliterates not only the uncommitted changes, but all commits after <commit>, as well.
Discussion
All of the above invocations are used to remove changes from a repository. Without the --hard flag, git reset is a way to clean up a repository by unstaging changes or uncommitting a series of snapshots and re-building them from scratch. The --hard flag comes in handy when an experiment has gone horribly wrong and you need a clean slate to work with.
Whereas reverting is designed to safely undo a public commit, git reset is designed to undo local changes. Because of their distinct goals, the two commands are implemented differently: resetting completely removes a changeset, whereas revertingmaintains the original changeset and uses a new commit to apply the undo.
Git Tutorial: Revert vs Reset
Don't Reset Public History
You should never use git reset <commit> when any snapshots after<commit> have been pushed to a public repository. After publishing a commit, you have to assume that other developers are reliant upon it.
Removing a commit that other team members have continued developing poses serious problems for collaboration. When they try to sync up with your repository, it will look like a chunk of the project history abruptly disappeared. The sequence below demonstrates what happens when you try to reset a public commit. The origin/master branch is the central repository's version of your localmaster branch.
Git Tutorial: Resetting an Public Commit
As soon as you add new commits after the reset, Git will think that your local history has diverged from origin/master, and the merge commit required to synchronize your repositories is likely to confuse and frustrate your team.
The point is, make sure that you're using git reset <commit> on a local experiment that went wrong—not on published changes. If you need to fix a public commit, the git revert command was designed specifically for this purpose.
Examples
Unstaging a File
The git reset command is frequently encountered while preparing the staged snapshot. The next example assumes you have two files called hello.py and main.py that you've already added to the repository.
# Edit both hello.py and main.py
# Stage everything in the current directory
git add .
# Realize that the changes in hello.py and main.py
# should be committed in different snapshots
# Unstage main.py
git reset main.py
# Commit only hello.py
git commit -m "Make some changes to hello.py"
# Commit main.py in a separate snapshot
git add main.py
git commit -m "Edit main.py"
As you can see, git reset helps you keep your commits highly-focused by letting you unstage changes that aren't related to the next commit.
Removing Local Commits
The next example shows a more advanced use case. It demonstrates what happens when you've been working on a new experiment for a while, but decide to completely throw it away after committing a few snapshots.
# Create a new file called 'foo.py' and add some code to it
# Commit it to the project history
git add foo.py
git commit -m "Start developing a crazy feature"
# Edit 'foo.py' again and change some other tracked files, too
# Commit another snapshot
git commit -a -m "Continue my crazy feature"
# Decide to scrap the feature and remove the associated commits
git reset --hard HEAD~2
The git reset HEAD~2 command moves the current branch backward by two commits, effectively removing the two snapshots we just created from the project history. Remember that this kind of reset should only be used on unpublished commits. Never perform the above operation if you've already pushed your commits to a shared repository.
git rebase
Rebasing is the process of moving a branch to a new base commit. The general process can be visualized as the following:
Git Tutorial: Rebase to maintain a linear project history.
From a content perspective, rebasing really is just moving a branch from one commit to another. But internally, Git accomplishes this by creating new commits and applying them to the specified base—it's literally rewriting your project history. It's very important to understand that, even though the branch looks the same, it's composed of entirely new commits.
Usage
git rebase <base>
Rebase the current branch onto <base>, which can be any kind of commit reference (an ID, a branch name, a tag, or a relative reference to HEAD).
Discussion
The primary reason for rebasing is to maintain a linear project history. For example, consider a situation where the master branch has progressed since you started working on a feature:
Git Rebase Branch onto Master
You have two options for integrating your feature into the masterbranch: merging directly or rebasing and then merging. The former option results in a 3-way merge and a merge commit, while the latter results in a fast-forward merge and a perfectly linear history. The following diagram demonstrates how rebasing onto master facilitates a fast-forward merge.
Git Tutorial: Fast-forward merge
Rebasing is a common way to integrate upstream changes into your local repository. Pulling in upstream changes with git merge results in a superfluous merge commit every time you want to see how the project has progressed. On the other hand, rebasing is like saying, "I want to base my changes on what everybody has already done."
Don't Rebase Public History
As we've discussed with git commit --amend and git reset, you should never rebase commits that have been pushed to a public repository. The rebase would replace the

locus of attention
or focus of attention; the single source or location of sensory input that a person attends to at a given time, such as the point in space that they're looking at and able to devote mental resources to interpreting. In some cases, expertise can reduce the need for attentional resources, leading to the effect of being able to attend to multiple sources.


Comprehensive National Power
From Wikipedia, the free encyclopedia
Jump to navigation Jump to search
Comprehensive National Power (CNP) (Chinese: 综合国力; pinyin: zōnghé guólì) is a putative measure, important in the contemporary political thought of the People's Republic of China, of the general power of a nation-state. CNP can be calculated numerically by combining various quantitative indices to create a single number held to measure the power of a nation-state.[citation needed] These indices take into account both military factors (known as hard power) and economic and cultural factors (known as soft power).
A fairly simplistic and effective index was developed by Chin-Lung Chang. It uses critical mass, economic capacity and military capacity. Due to its indicators, it is often repeatable and easy to define, making it comparable to the Human Development Index in understanding and reliability.[1]
The book "Comprehensive National Power- A Model for India", a project of United Service Institution of India explains how CNP is calculated and also shows various methods of calculation with various tables, charts, diagrams.[2]
National Strategic Resources[edit]
Michael Porter lists five major resources, that is, physical, human, infrastructure, knowledge and capital resources. Accordingly, the national strategic resources are divided into eight categories, with 23 indictors.[3] Those categories constitute CNP:[4]
 - Economic resources
 - Natural resources
 - Capital resources
 - Knowledge and Technology resources
 - Government resources
 - Military resources
 - International resources
 - Cultural resources

The news that has emerged is that the work on the new second pipeline from Chembarambakkam reservoir in the Kancheepuram district to the drinking water pumping station of Metro water at Koyambedu is in its final stages. It is now brought to light that after the completion of work the residents in south Chennai would be able to get water pumped from the reservoir in Chembarambakkam.
The water treatment plant at Chembarambakkam could treat and supply 560 MLD of water per day. This was according to a senior officer from the CMWD. Currently, with a single pipeline, only 265 MLD is being treated and distributed. It is noteworthy that to increase the supply quantity from Chembarambakkam it was proposed that a second pipe be laid. In 2022, the work on the new second pipeline began at a cost of Rs 44.33 crores. Till now, 75% works have been completed.
It must be taken into account that a portion of the pipeline is cutting across the Chennai- Bengaluru national highway. A state of art technology would be used to lay a 3000mm diameter pipeline at a depth of 20m. By this, road cutting could be avoided. After this, there would be an embedding of another pipeline with a diameter of 2000mm.

Nebraska DHHS Emergency Preparedness
Strategic National Stockpile
The Strategic National Stockpile (SNS) is a national resource of medical supplies ready and waiting to help states handle public health emergencies. It includes pharmaceuticals, medical supplies and medical equipment. The Centers for Disease Control and Prevention (CDC) has these "stockpiles" located around the country so states can have access to the supplies they need within 12 hours of requesting them.
DHHS' Role Warehouse
Receiving, shipping and storing the stockpile is a complex operation involving a lot of people from DHHS, other state agencies and the federal government as well. At DHHS we've recruited approximately 40 people to help with the process and are always looking for more volunteers. Among other duties, our employees are responsible for unloading the shipment, managing inventory, maintaining quality control, and repackaging supplies for further distribution.
The SNS Program is an essential response component of CDC's larger Bioterrorism Preparedness and Response Initiative. For more information, see the CDC Public Health Emergency Preparedness and Response Website.

How to Use the VAM Web Site Simulations with
There are two ways that you can use the simulations on the VAM web
site in Powerpoint presentations depending on whether you have fast
Internet access in the lecture room.
If you have fast Internet access in the lecture room:
Create a slide with hypertext that points to a URL for the simulation
that you want to use. During the lecture, click on the hypertext to
access the desired simulation. Run the simulation. When you are done
using the simulation, use the back arrow button on your web browser
toolbar to return to your slide show.
If you do NOT have fast Internet access in the lecture room:
STEP1. To teach with the desired simulation in an area without fast
Internet access, first access the simulation from a laptop, notebook
or portable computer at a nearby location with Internet access. Once
the simulation is working the computer can be disconnected from the
Internet. Make sure your battery has sufficient charge for the trip.
Keeping your portable computer powered and your web-browser running,
transport the computer to the location without Internet access and you
should be able to use the simulation there. If you will use the VAM
simulation and your laptop goes into "sleep" mode, click on
"Reset" (on the orange column on the right of the VAM simulation
screen) and then "Pause Simulation" (an instructor VAM feature)
before transport. When you arrive at the lecture hall, click on "Reset"
before using the VAM simulation.
STEP 2. Create your Powerpoint presentation and create a page with placeholder
text to remind you to go to the simulation. Open your Powerpoint slide
show. When you get to the reminder slide, press the "Alt"
and "Tab" buttons simultaneously. A series of icons representing
the different programs running should be displayed. To navigate to and
select the desired program, keep the "Alt" key down while
pressing and releasing the "Tab" key until the desired icon
is selected. When the icon representing the browser running the simulation
is selected, a square will appear aroud the "e" icon if you
are using Microsoft Internet Explorer. When the desired icon is selected,
release the "Tab" key to bring that program "to the front".
When you are done using the simulation, use the "Alt"/"Tab"
key combination to select the Powerpoint slide show icon and resume

Ritual de sobrevida
In Cuba, the Virgin of Charity or Virgen de la Caridad del Cobre is venerated as their nation's patroness and holds the additional title of "Virgin for Cuban Independence." For Afro-Cubans who practice Santeria she is syncretized with the orisha Ochún. Does the image refer to the ritual crowning of the Virgin Mary, a Catholic ritual that often takes place in May, hence the expression Queen of May?
This handmade book is decorated with cotton wool and a sun and moon are added on the back. Behind the moon is a crown, decorated with a cross and a silver oval. The front sides depict a snake and the Vigía lamp, held by a hand that peeks out from behind the right cover.

Grammar Engineering Frequently Asked Questions
How do I constrain something to be not of a certain value?
The tdl formalism does not include any explicit negation operator. However, in most cases, you can use the logic of the type hierarchy to encode negative constraints.
For example, suppose your language has three cases, nominative, accusative, and dative, and that you want to constrain the value of CASE on some type to be not dative. Within this closed system, not dative is the same as nominative or accusative. Therefore, it suffices to define an intermediate supertype for nominative and accusative, which excludes dative:
case := *top*.
dat := case.
nom+acc := case.
nom := nom+acc.
acc := nom+acc.
Given this hierarchy, "The case is not dative" (equivalently, "The case is nominative or accusative") can be expressed thus:
[ CASE nom+acc ].

Sarah Maribu and her brother Michael are two archaeologists and explorers, that arrive by helicopter to an uncharted island and start to investigate the temples and other structures of a lost civilization.
Sarah Maribu and the Lost World is a hidden object game with elements of the adventure genre. Most of the time, the objective is to find and click on all the items shown as pictures on slots at the left side of the screen, on locations filled with assorted paraphernalia scattered throughout the scenery. The hint button shows the position of one of the required items, but takes thirty seconds to recharge after use. Some of the objects are stored inside the inventory, to be used later when solving puzzles.
The inventory can be accessed through the tools button at the bottom-left corner, sliding upwards to reveal all of its compartments. The objects have to be used as in most point-and-click adventures, by dragging and dropping them over logical places to perform an action or complete a task. Some of the objects can only be found inside one of the interactive windows showing another angle of the location, that appear after clicking on certain hotspots.
There are mini-games between each chapter, like the Simon implementation where the player has to repeat a color sequence in a set of drums, the weights puzzle where statuettes have to be distributed on columns to reach equilibrium, and other similar challenges.

A space is $F_\sigma$-discrete space if it is the countable union of closed discrete subspaces. Is it true that every subset of an $F_\sigma$-discrete space is of the type $G_\delta$?
share|improve this question
2 Answers 2
up vote 1 down vote accepted
The answer is yes. Suppose that $X$ is an $F_\sigma$ space as you have defined it, so that $X=\bigcup_n X_n$, where each $X_n$ is a closed discrete space. Suppose that $Y\subset X$ is any subset. For each $n$, note that $X_n-Y$ is closed in the discrete space $X_n$ and hence also closed in $X$, and so the complement $U_n=X-(X_n-Y)$ is open in $X$. Furthermore, $\bigcap_n U_n=Y$, since $Y\subset U_n$ and anything not in $Y$ is in some $X_n$ and hence thrown out of that $U_n$. So $Y$ is a countable intersection of open sets and hence $G_\delta$.
share|improve this answer
Yes, since closed discrete sets are hereditarily closed. Let $X$ be the space and $E_n$ the closed discrete sets, so $X = \bigcup\limits_{n=1}^\infty E_n$. Then given $S \subseteq X$, each $E_n \setminus S$ is still closed, so $S = \bigcap\limits_{n=1}^\infty (E_n \setminus S)^\complement$ shows that $S$ is a $G_\delta$.

Carraízo Dam is a concrete gravity dam located in the municipality of Trujillo Alto, Puerto Rico within the flow of the Río Grande de Loíza. Its construction was completed in 1953. Carraízo Dam impounds Loíza Lake which serves as Puerto Rico's main water reservoir.
Background and construction
At the end of the 1940s, the Puerto Rico Aqueducts and Sewers Authority (PRASA) proposed the construction of a dam at the Río Grande de Loíza in the Barrio Carraízo of Trujillo Alto with the intention of providing both water and electricity to the San Juan Metropolitan Area.
Construction of the dam began in 1950 and finished in 1954. As part of the construction, the dam included three hydroelectric turbines with a total capacity of 3 Megawatts for the provision of electricity. However, during the 1960s and 1970s, the turbines were shut down because their operation and maintenance wasn't considered cost-effective versus the cost of buying energy at the time.
In 1989 Hurricane Hugo caused overtopping of the dam, thereby flooding the hydroelectric facility and rendering it inoperable. It stayed closed until 2013, when PRASA elected to renovate the facility.
Carraízo dam is a concrete gravity dam. It features eight floodgates along its 210-meter body. The floodgates open at a height of 1 to 10 meters, but they are usually opened at 4 meters. The reservoir created by the Carraízo Dam is the Loíza Lake. Carraízo's water storage capacity is of 4,650,000 gallons, and 41.15 meters is its peak level.

SIMATIC S7-1500: Rapid Traverse/Creep Speed Positioning (2SpeedPositioning)
An axis can be positioned in many different ways. In this context, especially TIA Portal with the S7-1200 and S7-1500 controller families provides support in the form of technology objects. Very high positioning accuracy of the axis can be achieved. However, this is also reflected in the hardware used to control these axes.
If an axis is to be positioned with relatively little hardware or with lower, controlled accuracy, this can be achieved with the aid of position monitoring and a simple contactor circuit. To this end, the positioning axis can be moved at two different speeds and simply switched off at the desired target position at the appropriate time using a contactor. With this method, called rapid traverse/creep speed positioning, relatively high positioning accuracy of the axis can be achieved.
Controlled positioning in rapid traverse/creep speed mode first moves the positioning axis towards the target position at a high speed (rapid traverse). At a defined position, the speed is switched to a lower speed (creep speed) at which the axis can then be moved to the target position.
To implement the two speed levels of rapid traverse/creep speed positioning, for example, pole-changing motors with a simple contactor circuit or simple frequency converters that allow speed selection through digital inputs can be used. The axis position can be detected with incremental or absolute encoders.

File Chunking and Merging in C++
Icon Leave Comment
I got the idea for a file chunking program the other day while I was reading a Ruby article. I thought to myself, why not build a similar utility in C++? The idea of chunking a file (that is, taking a file and breaking it into smaller files) can be a useful utility when dealing with some rather big files. Perhaps if you mix it with some file compression before the chunking, it would be even better! The need for such a utility like this has diminished over recent years because of high bandwidth and larger storage mediums. However, some programs (like email) may still benefit from something like this. I will show you a simple example of breaking a file apart and then merging it back again into the original file... all right here on the Programming Underground!
<Swedish Chef from the Muppet Show in the kitchen throwing utensils and singing theme music>
The idea behind the chunking itself is not a complex one. What we need to do is locate a file, open it up, read so many bytes out of it, create a file for each bit we read and write that piece into the file. We then close that chunk file and open another and read more of the input file. We repeat the process until we reach the end of the original file.
Our chunking function is going to take three pieces of information. The full path to the file we want to chunk, the name we want to give each chunk (it will then append the chunk number) and the chunk size which the user can specify. So for instance if the user wanted to take "c:\input.txt" which is 330 bytes and tell it to chunk in segments of 50 bytes named "chunk", it is going to produce 7 files. 6 of those files will be 50 bytes and the last will be the remaining 30 bytes. They will be named "chunk.1", "chunk.2", "chunk.3" etc. I am sure you get the idea. ;)/>
We open the file input.txt and if everything is successful, we read out 50 bytes at a time and place them in new files. We continue the process until the input file reaches the end of the file. The code looks like this...

// Chunks a file by breaking it up into chunks of "chunkSize" bytes.
void chunkFile(char *fullFilePath, char *chunkName, unsigned long chunkSize) {
 ifstream fileStream;
 fileStream.open(fullFilePath, ios::in | ios::binary);
 // File open a success
 if (fileStream.is_open()) {
 ofstream output;
 int counter = 1;
 string fullChunkName;
 // Create a buffer to hold each chunk
 char *buffer = new char[chunkSize];
 // Keep reading until end of file
 while (!fileStream.eof()) {
 // Build the chunk file name. Usually drive:\\chunkName.ext.N
 // N represents the Nth chunk
 fullChunkName.clear();
 fullChunkName.append(chunkName);
 fullChunkName.append(".");
 // Convert counter integer into string and append to name.
 char intBuf[10];
 itoa(counter,intBuf,10);
 fullChunkName.append(intBuf);
 // Open new chunk file name for output
 output.open(fullChunkName.c_str(),ios::out | ios::trunc | ios::binary);
 // If chunk file opened successfully, read from input and
 // write to output chunk. Then close.
 if (output.is_open()) {
 fileStream.read(buffer,chunkSize);
 // gcount() returns number of bytes read from stream.
 output.write(buffer,fileStream.gcount());
 output.close();
 counter++;
 }
 }
 // Cleanup buffer
 delete(buffer);
 // Close input file stream.
 fileStream.close();
 cout << "Chunking complete! " << counter - 1 << " files created." << endl;
 }
 else { cout << "Error opening file!" << endl; }
}
As you can see, it is rather long and probably could be refactored a little. But stepping through it is not incredibly difficult. We open the input file, setup a buffer array which will hold each chunk read and then use that buffer to write to each file. The file name for each chunk is built using a string class (so make sure to include <string>) and then the chunk is written into it, closed and more input is read. The result of this function will yield the list of files ending in numbers.
Now once we have the chunks created, we will need a function that then takes each chunk file, opens it, reads it and puts it all into one file again.
As you can see we are opening each file in binary mode. This is so that we can not only read text files, but literally any file including jpg, exe files, dlls etc without having a serious problem or messing with bytes when we have a binary file.
The function to then merge the files together we call "joinFile". I guess I could have called it "mergeFile" or "glueFile" or something funny like that. This function also has a little helper function called "getFileSize" which simply gets the size of the chunk file so that it knows how big to make the buffer to read in the chunk. It goes a little bit like this...
// Finds chunks by "chunkName" and creates file specified in fileOutput
void joinFile(char *chunkName, char *fileOutput) {
 string fileName;
 // Create our output file
 ofstream outputfile;
 outputfile.open(fileOutput, ios::out | ios::binary);
 // If successful, loop through chunks matching chunkName
 if (outputfile.is_open()) {
 bool filefound = true;
 int counter = 1;
 int fileSize = 0;
 while (filefound) {
 filefound = false;
 // Build the filename
 fileName.clear();
 fileName.append(chunkName);
 fileName.append(".");
 char intBuf[10];
 _itoa(counter,intBuf,10);
 fileName.append(intBuf);
 // Open chunk to read
 ifstream fileInput;
 fileInput.open(fileName.c_str(), ios::in | ios::binary);
 // If chunk opened successfully, read it and write it to
 // output file.
 if (fileInput.is_open()) {
 filefound = true;
 fileSize = getFileSize(&fileInput);
 char *inputBuffer = new char[fileSize];
 fileInput.read(inputBuffer,fileSize);
 outputfile.write(inputBuffer,fileSize);
 delete(inputBuffer);
 fileInput.close();
 }
 counter++;
 }
 // Close output file.
 outputfile.close();
 cout << "File assembly complete!" << endl;
 }
 else { cout << "Error: Unable to open file for output." << endl; }
}
// Simply gets the file size of file.
int getFileSize(ifstream *file) {
 file->seekg(0,ios::end);
 int filesize = file->tellg();
 file->seekg(ios::beg);
 return filesize;
}
We give it the name of the chunk name we used in breaking the file and then the filename we want to merge the chunks as. We could improve this code a little where instead of attempting to read a buffer of "fileSize" we could work with a smaller buffer and keep reading until we reach the end of the chunk. You may want to think about such a change if you think the chunks will be extremely large (tens of megs or higher) and don't want to burn up a lot of memory.
For this utility I would suggest not trying to create chunk files which are in the multiple gigabyte size range. Probably a few megs each would do nicely for chunking a file that is a couple gigs. The balance would be to create decent sized chunks which you could transport without having to create hundreds of chunks.
This utility would have been perfect for back in the day when we used diskettes that could only hold 1.44 megs each. I believe DOS had a similar utility like this, but I figured it would be a nice little theoretical program you could play with and put into your programs if you needed one.
I hope you enjoy it. As with all code on the programming underground, this is in the public domain and free to use as you see fit. Enjoy the code tidbits and thanks for reading! :)

A localization method based on an enhanced particle filter incorporating tournament selection and Nelder-Mead simplex search (NM-EPF) for autonomous mobile robots navigating in a soccer robot game field is proposed in this paper. To analyze the environment, an omnidirectional vision device is mounted on top of the robot. Through detecting the white boundary lines relative to the robot in the game field, weighting for each particle representing the robot's pose can be iteratively updated via the proposed NM-EPF algorithm. Thanks to the hybridization effect of the NM-EPF, particles converge to the actual position of the robot in a responsive way while tackling uncertainties. Simulation and experiment results have confirmed that the proposed NM-EPF has better localization performance in the soccer robot game field in comparison to the conventional particle filter.

Ryerson's interior design program is teaching students more than design. Through specialized courses and competitions, the skills taught in class are put towards creating a more sustainable and accessible world.
"Design activism," a concept introduced into the program by associate professor Lorella Di Cintio, is the act of using interior design to create positive social change. Di Cintio started working at Ryerson in 2001 and began informally implementing it into her teachings through lesson themes and assignments, but it officially became part of the curriculum in 2007.
Currently, students from first to fourth year are working on final projects which reflect the themes of activism, for example, the criteria of using sustainable materials.
"It's co-mingling aesthetics with ethics," said Di Cintio. "You take the beauty of [design] and look at it ethically to figure out how you can talk about equity, diversity and inclusion through that work. It's very much what Ryerson is about."
Through design activism, students are given the opportunity to contribute to society through different projects centred around various social issues. For example, in the first year Design Dynamics Studio II course, students are taught about sustainability, food security and design solutions. This is most illustrated in their final utensil project which asks for students to design wooden utensils with the goal of them being accessible for everyone. Some pieces are also auctioned off and the proceeds go towards The Stop Community Food Centre.
Kelly Warlcroft designed a tea cup and said she is enjoying the project's element of activism.
"The whole intention of the project is to create a utensil that is universal and can be used by anyone and everyone," said Warlcroft. "Some people are focusing more on people with disabilities or people that struggle with hand motor skills, so they make utensils dedicated to helping those individuals."
The first-year students are currently working on their utensils and will be presenting them at their annual showcase on April 21 to 28. Past projects have also been showcased at the annual Interior Design Show, which takes place in January.
Along with the utensil project, Di Cintio also organizes field trips, both local and international, centred around design activism. As part of the fourth-year interior design course IRN 700, 12 students went on a self-funded field research trip to Guatemala in fall 2015 for 10 days. The students conducted a design workshop with school children there, and designed products that would help them, like classroom furniture. McKayla Durant said the trip shifted her view of interior design and opened her eyes to the possibilities she had in the field.
"That was an amazing trip, I've never been exposed to a developing country and as a designer it was amazing to see how many ways I could use my skills to make their way of life better," said Durant.
Over 10 days, the students were asked to create design solutions for their classroom or landscaping. While a few of Durant's classmates created designs for chairs or desks, she created a vertical garden.
"They talked a lot about wanting a garden, but they weren't allowed to plant anything or change anything because they didn't actually own the land, so I came up with the idea of a vertical garden," she said. "It's basically planters that are above ground. They have this really great connection with their food and they have such an integral cultural idea of food, so I really wanted to run with that and create a design to help them."
Students have also gone on trips to Mexico, and New York — where they built furniture out of sustainable cardboard for people with disabilities — and Ottawa Valley to visit the Algonquins of the Pikwàkanagàn First Nation.
The 2008 trip to the reserve came in the midst of Stephen Harper's formal apology to residential school survivors.
"We went there because there was funding available for First Nations reserves to start telling their story and their version of history," she said.
Di Cintio was approached to design them a transportable stage for those story-telling opportunities.
On a local level, many students and faculty members also partake in The Stop's Night Market, which is a cultural fundraiser with all-you-can-eat food, music and art. All the proceeds go towards The Stop Community Food Centre. This year, it is taking place on June 16 and 17 on Sterling road, and design students and professors will design and construct food carts for the participating chefs. Some first-year students will also submit their utensils to be sold at the market, but the focus is on the carts which need to be made with sustainable materials. Durant has participated in this fundraiser and design competition all four years of her Ryerson career.
"Basically we are taking any type of materials we can scavenge and create a cart out of it," she said. "We have these boards with holes in them, and we're basically creating this cart that's see-through but with walls. But the whole concept really is to try and be sustainable."
Along with Durant, professor Ruth Spitzer is also designing a cart for this year's fundraiser and this partnership between the school of interior design and the night market began in 2013.
"I think Ryerson's really leading in these discussions about activism and social change, which is really amazing," said Di Cintio.

The objective of this study was to evaluate the mutagenic potentialities of two samples of water from different sources namely: raw sewage, treated sewage. Genotoxicity test was conducted using two varieties of Vicia faba var; Giza 3 and var. Giza Blanca). Several endpoints were used to estimate the mutagenic activity in Vicia cells such as: 1-mitotic activity 2-nuclear abnormalities and 3-chromosomal aberrations. Chemical analysis revealed the inefficient treatment of sewage where, many elements increased after secondary treatment, and even those elements which decreased did not reach the safe limits for use. Genotoxicity test exhibited change in mitotic activity with all water samples, either by decrease in the mitotic index in Vicia var. G. 3 or increase in case of Vicia var. G. Blanca. Many types of chromosomal aberrations and nuclear irregularities were also produced after all treatments. The most frequent aberration was chromosome stickiness among different types of abnormalities such as: micronucleus, banded chromosomes, bridges, laggard chromosomes and ring chromosome. The higher percentage of chromosomal aberrations is exhibited by raw sewage. The current data demonstrated the occurrence of mutagenic compounds in sewage water after secondary treatment and this requires further treatment to remove them. Moreover, their application to irrigate agricultural land must be stopped because of the mutagenic effects of plants irrigated by such waters.

Fiber Arts Exhibit at Sacred Heart University is Sure to Pleasecomments (2) May 12th, 2008
"The history of fiber can be traced to the beginnings of civilization. With uses dating from the Stone Age, approximately 2.5 million years ago, such natural fibers as flax, cotton, wool and silk have been discovered in ancient burial sites in Egypt, Babylonia, Peru, and Great Britain," according to Nisha Drinkard of William Paterson University.
Drinkard curated Contemporary Fiber, the current exhibit at The Gallery of Contemporary Art at Sacred Heart University (Fairfield, Connecticut), which features fiber art from 22 purveyors and is on display until May 29, 2008.
Their offerings range from dresses to framed work on canvas, but all entries are made mainly with textiles. Techniques used to manipulate the fibers include knitting, sewing, stitching, weaving, and quilting.

What are the advantages of tube furnaces
What are the advantages of tube furnaces
What are the excellent properties of the tubular resistance furnace? As a kind of heating and temperature measuring material equipment, there are many reasons why it is widely used in metallurgy, glass, heat treatment, new energy, abrasive tools and other industries.
First, the tube furnace has a mature manufacturing process and a simple furnace design structure, which is very easy to operate and control, and can produce uninterrupted production, which can greatly improve work efficiency.
Secondly, the yield of ethylene and propylene is high and the concentration is high, the energy consumption is very small, but the heat efficiency is extremely high.
Third, most of the waste gas in the production process can be recycled, which is conducive to energy saving and environmental protection. It can also be combined with multiple tube furnaces for large-scale production.
I have shared some of the advantages of box-type muffle furnaces and tube furnaces. Friends in need can pay attention to Luoyang Songdao Induction Heating Technology Co., Ltd.-a manufacturer of tube furnaces and high-temperature furnaces.


Hallmark Card Studio for Mac requires internet access. This is true even for boxed versions on DVD.
If you are getting errors saying it cannot connect to the internet, or it cannot load some of the designs, please start by verifying that you have a good, constant connection to the internet. The program requires it.
If your Mac is currently connected, you should check your anti-virus, firewall or anti-malware software on your computer.
Often it is one of these programs blocking the Hallmark program's access to the internet.
In some instances the connection may be too slow, or have too much latency for the program.
This is especially true on satellite internet (such as HughesNet), internet via a cellular connection, dialup, and some slower DSL ISPs under 1 megabit.
You can clear cache by following those steps
1. Close the program thru Hallmark Card Studio>Quit Hallmark Card studio, or via Force Quit
2. Use Go To Folder, in the Finder's Go menu (also accessible by pressing Shift+Command+G)
3.Type in ~/Library and click Go
4. Double-click "Application Support" folder
5. Double-click "Hallmark Card Studio" folder
6.Drag the Backup folder to the Trash bin

Malvern's newest initiative focuses on character
Chris Bunn
Malvern SealThe Character and Integrity Task Force is a new way to review the school's disciplinary philosophy, policy, and implementation
The Character and Integrity Task Force is a new initiative that aims to review the school's disciplinary philosophy, policy, and implementation. Chaired by Dean of Students Mr. Tim Dougherty, the task force will also include other members of Malvern's community such as Mr. Talbot, Father Flynn, Mrs. Feeney, Mr. Valyo, and Mr. Algeo.
Along with academic integrity, the main focus of the group will be on other character issues such as drugs and alcohol, digital citizenship, and respect for differences, according to Head of School Mr. Talbot.
However, Talbot is quick to note that this list isn't exhaustive, but rather representative. Issues that arise over time will also be addressed. Input from parents and faculty will also be considered.
Despite the fact that the basic structure and purpose of the Character and Integrity Task Force has been developed, some of the details have not yet been planned out. Because of this, the task force has not been publically announced, according to Talbot.
The reasons for starting this task force are twofold, said Talbot.
One of the reasons is due to a series of incidents, some of which have to do with academic integrity and other behavioral incidents such as drinking on Christian service trips and vandalizing property, according to Talbot.
"The other reason is rooted in Malvern's own Augustinian mission and values," Talbot said.
Most members of the Malvern community will get a chance to participate on the Task Force, according to Talbot. However, most roles within the task force will be limited. "I want to make sure that people understand their roles. The way I would characterize it is [that] there are three kind of species of people involved in this," said Talbot.
"There are people who ultimately decide what we change or what we preserve. That would be the members of the leadership team and the educational administrator team," Talbot explained.
"The next group would be the recommenders. So the other members of the task force [such as] teachers, staff, alumni, trustees, parents."
"The third group would be consultants or advisors. They may or may not make a recommendation. But they would be sharing their perspectives. Students would share perspectives. Other parents not on the task force would share perspectives. But they are not at the point of making a formal recommendation," Talbot said.
According to Talbot, students might serve for the most part as advisors or consultants. However, there may be instances where students could become a subcommittee and submit a formal recommendation.
The reason for the limited role of students in this task force is due to an inherent conflict of interest.
"[As a student,] you want to have a say at the table. But we also have to make sure that we are not creating conflicts of interest where students are actually recommending or deciding upon policies that might, for example, minimize or eliminate penalties, when in fact we really do need those things." Talbot explained.
At this point, the administration is unsure of how this task force will be received by students. "I can't anticipate student perception until changes occur," says Mr. Dougherty.
However, Dougherty is looking forward to the discussion. "It is exciting to self assess and see what is needed and what is not," he said.
As the Character and Integrity task force starts to become more defined, Talbot still believes that the purpose of this task force is to improve, rather than fix.
"I don't think that we have a corrupt culture. I don't think that we have some rotten core that needs to be carved out or replaced. I think this is a healthy place. And that's a good thing." Talbot said.
"Malvern kids are good kids. For me, it is about taking a good thing and making it better."

How do i manage moving the observer and rotating him on the spot?

You cant really "move" the camera, you have to move/rotate the object instead.
say you want the camera to turn 90deg, you actually have to rotate the matrix 90deg to the other direction beofre you draw the cube...
I know I cant explain very well, but I guess you get the point..
JLawson

There is no such thing as a camera in OpenGL, so I will use the word to describe the position of the "observer".
There is a function called gluLookAt that takes 9 arguments.
the first three are float values that are the camera's x, y, z coordinates respectively.
the second three are float values that are the x, y, and z coordinates that the camera is looking at (respectively).
The last three are floats also, and they are the camera tilt. They should always be 0,1,0, unless you want your world to be upside down, then they would be 0,-1, 0
