Lesson: Understanding Public Hearings

Introduction:
A public hearing is a meeting where members of the public can provide input or comments on a particular issue. These hearings are typically held by government agencies or organizations to gather feedback from the community. In this lesson, we will learn about the purpose of public hearings, how they work, and why they are important.

Section 1: The Purpose of Public Hearings

The purpose of a public hearing is to allow members of the public to voice their opinions or concerns about a particular issue. This can be done in person, by phone, or in writing. Public hearings are typically held when a government agency or organization is considering a new law, policy, or project that may affect the community.

Question: Why do you think public hearings are important?
Answer: Public hearings are important because they give people the opportunity to have their voices heard and to influence decisions that affect them. They also help ensure that decisions are made transparently and with input from the community.

Section 2: How Public Hearings Work

Public hearings usually follow a set format. First, the organization holding the hearing will present information about the issue being discussed. Then, members of the public will have the opportunity to speak or provide written comments. The organization will then review all the comments and feedback received before making a decision.

Question: What kind of information might be presented at a public hearing about hospital funding?
Answer: At a public hearing about hospital funding, the organization might present information about the current state of hospital funding, any proposed changes to the budget, and how these changes could affect patient care or services.

Section 3: Why Public Hearings Are Important

Public hearings are important because they allow for transparency and accountability in government decision-making. They also give people the opportunity to have their voices heard and to influence decisions that affect them. By attending a public hearing, you can learn more about an issue and how it may impact your community.

Question: Why is it important for government agencies to hold public hearings?
Answer: It is important for government agencies to hold public hearings because it allows them to gather input from the community and make decisions that reflect the needs and concerns of the people they serve. Public hearings also help ensure that decisions are made transparently and with input from the community.

Conclusion:
In conclusion, public hearings are an important tool for government agencies and organizations to gather feedback from the community. By attending a public hearing, you can learn more about an issue and how it may impact your community. Remember that the purpose of a public hearing is to allow members of the public to voice their opinions or concerns about a particular issue.

Lesson: How to Write a Script
Introduction:
Writing a script is an essential skill for anyone interested in filmmaking or screenwriting. In this lesson, we will explore the basics of scriptwriting, including formatting, structure, and character development. We will also discuss how to use software to help with the writing process.
Formatting:
The first step in writing a script is to learn the proper formatting. This includes using the correct font, spacing, and margins. There are specific guidelines that must be followed when formatting a script, and these guidelines are typically outlined in a screenwriting software program.
Structure:
The structure of a script is important because it helps to guide the story and keep the reader engaged. A typical script will have three acts: Act 1, Act 2, and Act 3. Each act has a specific purpose and should be structured accordingly.
Act 1: The first act is where the story is introduced, and the characters are introduced. This act should be fast-paced and engaging to keep the reader interested.
Act 2: The second act is where the conflict is introduced, and the characters must face challenges. This act should be the longest and most dramatic.
Act 3: The third act is where the resolution is reached, and the story comes to an end.
Character Development:
Character development is crucial to any good script. Characters should be developed fully so that the reader can connect with them emotionally. This includes giving them backstories, motivations, and personalities.
Software:
There are many software programs available that can help with scriptwriting. One of the most popular is Final Draft. This software allows writers to format their scripts properly and easily make changes as they write.
Conclusion:
In conclusion, writing a script is an essential skill for anyone interested in filmmaking or screenwriting. By following the proper formatting guidelines, structuring the story correctly, and developing characters fully, writers can create compelling and engaging scripts. Additionally, using software such as Final Draft can make the writing process easier and more efficient.

Q:

How to prevent object copying in arraylIst in java

I have an arrayList of object Player. Player has field id, and score. suppose arrayList has player object with id:1, score:200 now when i add player with id:1 and score :300, arraylist have now two object but both with score 200. whereas it should be one with score 100 and one with score.
I tried clone() method as arrayList.add(player.clone()) but it did not solve my problem.
code:
Player player= playerService.getPlayerById(id);
player.SetScore(100);
challenge.getPlayerList().add(player.clone());
here challenge is an object which has an attribute playerlist

Please suggest.
Thanks.

A:

Its a common mistake to assume that adding an object to a list/array copies it.
If truth, you add references to a collection, not the object and it is the reference which is copied.
You create a new object each time new or clone() is called only.
// Don't do this
Player p = new Player(1, 100);
list.add(p);
list.add(p); // adds a reference to the same object.

// Do this
list.add(new Player(1, 100));
list.add(new Player(2, 200));

A:

Without you showing some code, I'm guessing you're adding the same Player object but with different values. If you:

Add a Player with id: 1 and score: 100
Change the values of that Player object to score: 200
Add that object again

You will have 2 Players in your list with the last values of the Player object.
Somewhere you need to do a new Player() with new values, not just re-use the same Player object.

Lesson:
### Section 1: Introduction
In this lesson, we will learn about object cloning in Java and how to prevent it when working with arrays and collections. We will also explore the concept of reference types and how they affect object copying.
### Section 2: Object Cloning in Java
When you create an object in Java, you are actually creating a reference to that object. This reference can be passed around and used to access the object's properties. When you add an object to a collection, such as an array or a list, you are adding a reference to that object, not the object itself. This means that if you add the same object to a collection multiple times, you will have multiple references to the same object.
### Section 3: Preventing Object Cloning
To prevent object cloning in Java, you need to make a copy of the object before adding it to the collection. One way to do this is to use the Object.clone() method. However, this method is not available for all classes, so you may need to create your own copy method.
Here's an example of how to prevent object cloning when adding objects to an arrayList:
```
public class Player {
    private int id;
    private int score;
    public Player(int id, int score) {
        this.id = id;
        this.score = score;
    }
    public int getId() {
        return id;
    }
    public void setId(int id) {
        this.id = id;
    }
    public int getScore() {
        return score;
    }
    public void setScore(int score) {
        this.score = score;
    }
    public static Player createPlayer(int id, int score) {
        return new Player(id, score);
    }
}
public class Main {
    public static void main(String[] args) {
        ArrayList<Player> players = new ArrayList<>();
        players.add(Player.createPlayer(1, 100));
        players.add(Player.createPlayer(1, 200));
        System.out.println(players);
    }
}
```
In this example, we create a Player object with the id 1 and the score 100. We then add this object to an arrayList called players. We then create another Player object with the same id and score, but this time we call the createPlayer method to make a copy of the object before adding it to the arrayList. When we print out the players array, we see that we have two distinct objects with different scores.
### Section 4: Conclusion
In this lesson, we learned about object cloning in Java and how to prevent it when working with arrays and collections. We also explored the concept of reference types and how they affect object copying. By understanding these concepts, we can write more efficient and effective code.

Title: Understanding Abdominal Fat and its Relation to Heart Disease

Introduction:
Abdominal fat is a common health problem that affects many people worldwide. It has been linked to various health issues, including heart disease. In this lesson, we will learn about abdominal fat, its impact on heart disease, and ways to reduce its risk.

Section 1: Understanding Abdominal Fat

Topic 1: What is Abdominal Fat?
Abdominal fat is a type of fat that accumulates around the stomach area. It is also known as visceral fat or central obesity. It is different from subcutaneous fat, which is the fat that lies just beneath the skin.

Topic 2: How does Abdominal Fat affect Health?
Abdominal fat has been linked to several health issues, including heart disease, diabetes, and high blood pressure. It is not just about appearance; it can also lead to serious health problems.

Section 2: Abdominal Fat and Heart Disease

Topic 1: How does Abdominal Fat increase the risk of Heart Disease?
Research has shown that abdominal fat increases the risk of heart disease in several ways. It can cause inflammation, increase the levels of certain hormones and proteins, and lead to insulin resistance. All these factors can contribute to the development of heart disease.

Topic 2: Measuring Abdominal Fat
Doctors use different methods to measure abdominal fat. One common method is to measure the waist circumference. A high waist circumference is associated with an increased risk of heart disease. Another method is to measure the hip circumference. This can give a better picture of the distribution of fat in the body.

Section 3: Reducing the Risk of Abdominal Fat

Topic 1: Lifestyle Changes
Losing weight and maintaining a healthy weight can help reduce the risk of abdominal fat. This can be achieved through a balanced diet, regular exercise, and getting enough sleep.

Topic 2: Medications
In some cases, medications may be prescribed to help reduce abdominal fat. These medications work by targeting specific hormones and enzymes involved in the storage of fat.

Conclusion:
Abdominal fat is a significant risk factor for heart disease. By understanding its impact and taking steps to reduce the risk, we can improve our overall health and wellbeing. Remember, a healthy lifestyle, including a balanced diet, regular exercise, and enough sleep, can go a long way in reducing the risk of abdominal fat and heart disease.

Lesson: How to Solve a Candy Crush Level

### Introduction
Welcome to our lesson on how to solve a Candy Crush level. In this lesson, we will teach you how to approach and solve a Candy Crush level by breaking it down into manageable steps. We will use Level 1292 as an example, but the principles taught in this lesson can be applied to any level.

### Step 1: Analyze the Board
The first step in solving a Candy Crush level is to analyze the board. Look at the layout of the candies, jellies, and other obstacles. Identify which candies can be matched easily and which ones are more difficult to match. Take note of the color bombs, striped candies, and other power-ups that can help you clear the level.

### Step 2: Create a Plan
Once you have analyzed the board, create a plan on how you will clear the level. Look for opportunities to create special candies such as striped candies and color bombs. Identify which jellies you can clear with a single move and which ones will take multiple moves. Make sure your plan takes into account the number of moves you have and the target score.

### Step 3: Execute the Plan
Now that you have a plan, execute it! Start by making matches that will help you create special candies or clear jellies. Be patient and strategic in your moves, taking into account the number of moves you have and the target score. Don't be afraid to undo moves if you realize you made a mistake.

### Step 4: Adapt the Plan
As you execute your plan, you may find that your initial strategy needs to be adapted. Maybe you didn't account for a blocker or a particularly difficult candy to match. That's okay! Don't be afraid to change your plan as you go along. Keep an eye out for new opportunities to create special candies or clear jellies, and adjust your strategy accordingly.

### Step 5: Check Progress
As you play, keep track of your progress towards the target score. If you find that you are falling behind, reassess your plan and see if there are any changes you can make to catch up. Remember, it's important to stay calm and focused as you play.

### Step 6: Finish Strong
Once you have a good plan and are making progress towards the target score, finish strong! Keep making matches and clearing obstacles until you reach the target score. Don't get too complacent, though – keep an eye on your remaining moves and the clock, if applicable.

### Conclusion
In conclusion, solving a Candy Crush level requires careful analysis, strategic planning, and adaptability. By following these steps, you can approach any level with confidence and determination. Good luck, and happy crushing!

Lesson: Introduction to Real Estate

### Section 1: What is Real Estate?
Real estate refers to the land and buildings on it, along with any natural resources such as minerals or water. It can also refer to the rights of ownership and possession of these assets. Real estate can be used for residential, commercial, or industrial purposes, and its value is determined by factors such as location, size, and condition.

### Section 2: Types of Real Estate
There are four main types of real estate: residential, commercial, industrial, and agricultural. Residential real estate includes single-family homes, condominiums, townhouses, and cooperatives. Commercial real estate includes office buildings, retail spaces, warehouses, and apartment buildings that are used for business purposes. Industrial real estate includes factories, manufacturing plants, and other facilities used for production or distribution. Agricultural real estate includes farmland, ranches, and other properties used for farming or ranching activities.

### Section 3: How to Invest in Real Estate
One way to invest in real estate is to buy rental properties and collect monthly rent from tenants. Another way is to invest in real estate investment trusts (REITs), which are companies that own and operate income-producing real estate. REITs pay out most of their taxable income as dividends to shareholders. Another option is to invest in real estate investment groups (REIGs), which are groups of investors who pool their money to purchase and manage real estate properties.

### Section 4: Risks and Rewards of Investing in Real Estate
Investing in real estate can be risky because property values can fluctuate due to market conditions, and vacancies or maintenance costs can reduce profits. However, real estate investments can also provide stable long-term returns, especially if the property is managed well and located in a desirable area. Additionally, real estate investments can provide tax benefits, such as depreciation deductions and capital gains exemptions.

### Section 5: Conclusion
Investing in real estate can be a smart way to diversify your investment portfolio and potentially earn passive income. By understanding the different types of real estate, how to invest in them, and the risks and rewards involved, you can make informed decisions about whether real estate investment is right for you.

Lesson: Virtual Music Performance

## Section 1: Introduction
In this lesson, we will learn about virtual music performance and how technology has enabled musicians to perform together even when they are not physically present in the same location. We will explore the challenges and benefits of virtual performances and how they have become more common in recent years.

## Section 2: Theoretical Concepts
A virtual music performance is a concert that takes place over the internet. Musicians can perform together even if they are in different locations. This is made possible by using software that allows the musicians to play together in sync. The software also allows for real-time audio and video feeds, so the musicians can see and hear each other during the performance.

One of the challenges of virtual performances is latency, which is the delay in the sound or video signal. This can cause the musicians to be out of sync with each other. To overcome this challenge, the musicians must use low-latency equipment and software that minimizes the delay between the signal being sent and received.

Another challenge is technical difficulties, such as poor internet connections or software glitches. These can cause disruptions during the performance. To avoid this, the musicians must have backup plans, such as pre-recorded tracks or alternative software.

Benefits of virtual performances include the ability to reach a wider audience and the flexibility to perform from any location. Virtual performances also allow for creative visual elements, such as special effects and animations.

## Section 3: Practical Examples
Let's consider a virtual performance by a band. The band members are located in different cities, so they use software to record their parts separately and then mix them together. They also use video conferencing software to rehearse and discuss the performance. During the performance, the band members wear headphones to hear each other clearly and use a click track to stay in sync. The performance is streamed live on social media, and the band members interact with the audience through chat.

## Section 4: Critical Thinking
What are some advantages and disadvantages of virtual performances compared to in-person performances? How might technology continue to impact the way musicians perform and connect with audiences?

## Glossary
- Latency: The delay in the sound or video signal
- Low-latency: Equipment and software that minimizes the delay between the signal being sent and received
- Backup plan: A precautionary plan in case of technical difficulties
- Click track: A metronome that clicks at a consistent tempo

## Conclusion
In this lesson, we learned about virtual music performances and how technology has enabled musicians to perform together even when they are not physically present in the same location. We explored the challenges and benefits of virtual performances and discussed a practical example of a band performing virtually. We also engaged in critical thinking about the advantages and disadvantages of virtual performances and how technology may continue to impact the way musicians perform and connect with audiences.

I have been trying to chase down information on using the audio channel to downlink telemetry for several days. Every seemingly hopeful path I've followed has led to a deadend. If you succeed in finding anything, PLEASE post a link here.
- Don

Kind of late to the game, but I seem to have the same module. It has the same top number, but the bottom number is FD0906AT3. Interesting that mine was manufactured in 06/09. Was yours manufactured in 35/08?
Mine has a yellow wire that comes out near the RF connector and runs underneath the Rx between the module and the case. It isn't connected to anything on the end outside the module. Any idea what that is? It looks like an antenna. Is this a transceiver module in other applications?
Speaking to quality control, mine also has a label on the other side that says "1.3GHZ Receiver". It isn't.
Cheers,
Don

Mr. RC-Cam,
I suppose it could be "ground effect", but the behavior is the same as T.I. says happens when the polonium weakens. I was hoping that the polonium was originally used to increase the sensitivity and that it might not be required with state-of-the-art circuitry. I've sent a PM to Helmut Lelke, asking him to describe his current sensors, but haven't received a reply. If I were to find out that he no longer uses polonium, then I could get excited about this, again.
- Don

I've decided this is not a viable alternative for stabilization - at least not for me. I built a clone of the Chinese fella's system. It does actually respond to changes in tilt, but as TI suggested, it acts like a gyro. Maybe with the polonium it would behave as advertised, but that isn't the way I want to go. I'll probably attempt the accelerometer/gyro/Kalman filter solution, next. Meanwhile, I have my co-pilot and I'm attempting to gain an understanding of Kalman filters.
- Don

TI,
Thanks for the info. I've been trying to contact him to no avail. His email address on CRRC doesn't work.
I agree with you on placing the FET stages at the extremities and that's what I've done in my experiments. My hope, though, is to build something that doesn't require the isotope.
It may be wishful thinking, but I don't see any sign of isotopes on his Albatross II photos or drawings. Were your discussions with him pre, or post, Albatross II?
- Don

Is either of you familiar with Helmut Lelke's use of this method in his gliders? It appears he's been doing it successfully for over 20 years. I came across an article in "RC Soaring Digest" where he talks about Maynard Hill helping him with his initial attemps. Interesting read. Let me know if you haven't already seen it and I'll try posting it.
- Don

Terry and Mr. RC-Cam,
I didn't mean to imply that I had translated the whole document. I used bablefish.altavista.com to translate certain phrases and sentences. The translations read a lot like some of the users manuals we've all seen come out of Asia, but it was sufficient to give the flavor of what he was doing.
I've adapted his circuits to use components I had on hand, or could get my hands on, and I've breadboarded a bit of it to see if it shows any promise. The FETs, with 1" antennas, are amazingly sensitive. They pick up my waving a piece of plastic from across the room. Of course, that's what we want to filter out!
I'll know much more within the next few days and will post my findings here.
- Don

Anyone care to revive this topic? I've done a little "translating" and have sort of figured out what he's doing. BTW, the gyro wasn't part of the project. Rather, it was used to verify the output of the thing.
- Don

Q:

Cause of Kitten Diarrhea?

My kitten in 3 month old and losing weight due to diarrhea. Before de-worming, diarrhea was with blood, but now it is just stool. We give boiled chicken and kitten food (ROYAL CANIN). And sometimes yogurt and boiled rice. I asked the Vet but he says change the cat food. It is the same cat food that he suggested me during de-worming. So I bought 2kg bag. I am confused now what to feed to my kitten. Is it boiled chicken? Or the kitten food causing diarrhea.

A:

Ask your vet to clarify what they meant by changing the cat food.
My recommendation would be to feed only the Royal Canin kitten food. The yoghurt or boiled rice could be causing digestive issues, and are not part of an appropriate diet for a kitten or cat. Small amounts of chicken are likely not be a problem as long as the chicken is not flavoured and fully cooked, however until the diarrhea has resolved I would feed only the kitten food.
There are hundreds of different causes of diarrhea in kittens, ranging from the simple-to-treat (parasites) to difficult-to-treat (allergies), with every bacterium and virus in between. Some kittens will respond well to simplifying the diet, while others need further workup (bloodwork, fecal, possibly x-rays, etc) to get to an answer and appropriate treatment. Some kittens will become very dehydrated with severe diarrhea so it is important to not let diarrhea go untreated for too long.

A:

Only have two things to add to the other answer:
Watch the cat throughout the day, make sure they're not eating something they shouldn't be (like plants or carpet fibers). If you can't do that, maybe put them in a clean room where they can't get anything bad.
Also, please take your cat to get a workup at the vet! Would you like to have horrible chronic diarrhea? It probably won't be that expensive. Think of it as an investment that will pay out over 10-20 years of your cat's friendship.

Lesson: Introduction to Probability

### Overview
In this lesson, we will learn about probability, which is the chance or likelihood that an event will occur. We will cover the basics of probability, including the concept of independent events and conditional probability. We will also explore the use of probability trees and Venn diagrams to represent and solve probability problems.

### Section 1: Basic Concepts

**Topic 1: Independent Events**
An event is considered independent if the outcome of one event does not affect the outcome of another event. For example, flipping a coin twice - the outcome of the first flip does not influence the outcome of the second flip.

**Topic 2: Conditional Probability**
Conditional probability refers to the probability of an event occurring given that another event has already occurred. For example, if you roll a fair six-sided die, the probability of rolling a 3 given that the die landed on 2 or 3 on the previous roll is 1/2.

### Section 2: Representing Probabilities

**Topic 1: Probability Trees**
A probability tree is a diagram that represents the possible outcomes of a series of events. Each branch of the tree represents a possible outcome, and the probabilities of each outcome are listed next to the branches.

**Topic 2: Venn Diagrams**
A Venn diagram is a graphical representation of sets, where each set is represented by a circle. The areas of overlap between the circles represent the probabilities of events occurring.

### Section 3: Practice Problems

**Problem 1**
A fair six-sided die is rolled. What is the probability of rolling a 3, given that the die landed on 2 or 3 on the previous roll?

Solution:
Since the die is fair, the probability of rolling any number on the next roll is 1/6. However, if the die landed on 2 or 3 on the previous roll, there are only two possible outcomes (3 and 4) that would result in a sum of 5. Therefore, the probability of rolling a 3 given that the die landed on 2 or 3 on the previous roll is 1/2.

**Problem 2**
A bag contains 8 red balls and 4 blue balls. Two balls are drawn at random without replacement. What is the probability that both balls drawn are red?

Solution:
To solve this problem, we can use conditional probability. First, we need to find the probability of drawing a red ball on the first draw. There are 8 red balls and 12 total balls, so the probability is 8/12 or 2/3. After drawing one red ball, there are 7 red balls left and 11 total balls, so the probability of drawing another red ball is 7/11. Since these two events are independent, we multiply the probabilities to get the overall probability of drawing two red balls: (2/3) * (7/11) = 28/33.

### Glossary
- Probability: The chance or likelihood that an event will occur.
- Independent events: Events that do not affect each other's outcomes.
- Conditional probability: The probability of an event occurring given that another event has already occurred.
- Probability tree: A diagram that represents the possible outcomes of a series of events.
- Venn diagram: A graphical representation of sets.

### Conclusion
In this lesson, we learned about probability, independent events, and conditional probability. We also explored the use of probability trees and Venn diagrams to represent and solve probability problems. By understanding these concepts, we can apply them to real-world scenarios to make informed decisions and predictions.

Q:

ASP.NET - Get User ID For Seeding

I'm doing a code-first database and I was wondering how I can get the ID for the seeded users that I have stored.
In this part of the code, I am creating the users.
         //Users
        List<ApplicationUser> applicationUsers = new List<ApplicationUser>();
        applicationUsers.Add(new ApplicationUser() { Email = "person1@test.test", UserName = "person1@test.test" });
        applicationUsers.Add(new ApplicationUser() { Email = "person2@test.test", UserName = "person2@test.test" });
        applicationUsers.Add(new ApplicationUser() { Email = "person3@test.test", UserName = "person3@test.test" });
        applicationUsers.Add(new ApplicationUser() { Email = "person4@test.test", UserName = "person4@test.test" });
        applicationUsers.Add(new ApplicationUser() { Email = "person5@test.test", UserName = "person5@test.test" });

        foreach (ApplicationUser user in applicationUsers)
        {
            manager2.Create(user, "qweQWE123!@#");
            manager2.AddToRole(user.Id, "RegisteredUser");
        }

And that works well, the users are in my database, however, I have a model which uses the UserID as a foreign key. How would I get the GUID Generated from creating these users within the seeded method?
This is the model of the item model, the one which uses a User ID Foreign key.

}

This is how I fill in the item
itemList.Add(new ItemModels() { ItemTypeID = 1, ItemPrice = 1.67,  ItemQuantity = 1, QualityID = 1, UserId="What do i put here?" });

A:

In your loop you're already accessing the user.Id property in manager2.AddToRole().
The easiest way to seed your item is create the item object inside that loop then save after adding all the items.
var itemList = new List<ItemModels>();

foreach (ApplicationUser user in applicationUsers)
{
   manager2.Create(user, "qweQWE123!@#");
   manager2.AddToRole(user.Id, "RegisteredUser");

   // use user.Id for ItemModel then add to list
   itemList.Add(new ItemModels() { UserId = user.Id, ItemTypeID = 1, ItemPrice = 1.67,  ItemQuantity = 1, QualityID = 1 });

}

// then save your items here
context.Items.AddToRange(itemList);
context.SaveChanges();

Lesson: Getting User IDs in Code-First Database

Introduction:
In this lesson, we will learn how to get the User ID for seeded users in a code-first database. We will use C# and Entity Framework Code First to create a simple database with users.

Pre-requisites:
- Basic knowledge of C# and Entity Framework Code First
- Familiarity with creating databases and entities in Code First

Instructions:
1. Open your project in Visual Studio and create a new DbContext class.
2. Add the following code to the DbContext class to create the Users table:

```csharp
public class MyDbContext : DbContext
{
    public MyDbContext() : base() { }
    public DbSet<ApplicationUser> Users { get; set; }
}
```

3. Create a new class called `ApplicationUser` and add the following properties:

```csharp
public class ApplicationUser
{
    public int Id { get; set; }
    public string Email { get; set; }
    public string UserName { get; set; }
}
```

4. In the `DbContext` class, replace the `OnModelCreating` method with the following code:

```csharp
protected override void OnModelCreating(DbModelBuilder modelBuilder)
{
    modelBuilder.Entity<ApplicationUser>()
        .HasDatabaseGeneratedOption(DatabaseGeneratedOption.None);
}
```

5. Seed the database with users by adding the following code after the `OnModelCreating` method:

```csharp
public static void SeedDatabase(MyDbContext context)
{
    var applicationUsers = new List<ApplicationUser>
    {
        new ApplicationUser() { Email = "person1@test.test", UserName = "person1@test.test" },
        new ApplicationUser() { Email = "person2@test.test", UserName = "person2@test.test" },
        new ApplicationUser() { Email = "person3@test.test", UserName = "person3@test.test" },
        new ApplicationUser() { Email = "person4@test.test", UserName = "person4@test.test" },
        new ApplicationUser() { Email = "person5@test.test", UserName = "person5@test.test" }
    };

    context.Users.AddRange(applicationUsers);
    context.SaveChanges();
}
```

6. Now, you can get the User ID for each seeded user by querying the database. Add the following code to get the User ID for `person1`:

```csharp
using (var context = new MyDbContext())
{
    var person1 = context.Users.Find(1); // Replace 1 with the ID of person1
    Console.WriteLine("User ID for person1: " + person1.Id);
}
```

7. Run the code and observe the output. Repeat the process for other users by changing the ID in the `Find` method.

Conclusion:
In this lesson, we learned how to get the User ID for seeded users in a code-first database using C# and Entity Framework Code First. We created a simple database with users and seeded the database with five users. We then queried the database to get the User ID for each user. This skill is useful when working with databases and entities in code-first development.

**Lesson:** The Power of Superheroes and the Dangers of Unchecked Power

**Introduction:** Superheroes are often portrayed as invincible beings who can save the world from any threat. However, this power comes with great responsibility and consequences. In this lesson, we will explore the dangers of unchecked power and the importance of using power wisely.

**Section 1: Theoretical Concepts**

**Topic 1: The Power of Superheroes**

Superheroes possess extraordinary abilities that make them powerful beings. These abilities can range from superhuman strength, speed, agility, and intelligence to the ability to fly, shoot lasers from their eyes, or manipulate matter.

**Topic 2: The Dangers of Unchecked Power**

While superheroes have the potential to save the world, their power can also be dangerous if not used responsibly. If a superhero becomes too powerful, they may become a threat to humanity itself. This is because power can corrupt, and absolute power can corrupt absolutely.

**Section 2: Practical Examples**

**Example 1: The Sentry**

The Sentry is a fictional superhero created by Paul Jenkins and Jae Lee. He possesses incredible power, but also suffers from a bipolar disorder that results in an all-powerful evil creature being awakened in the world every time he uses his powers. This illustrates the danger of unchecked power and the importance of using power responsibly.

**Example 2: Superman**

Superman is another example of a powerful superhero who must use his power wisely. While he has the potential to save the world, he also has the potential to cause great harm if he is not careful. For example, if he were to use his heat vision to destroy everything in his path, he could easily cause more damage than any villain he faces.

**Section 3: Self-Debating Discussions**

**Topic 1: The Responsibility of Power**

As we have seen, power can be a double-edged sword. On one hand, it can be used to save the world. On the other hand, it can be used to destroy it. As superheroes, we must always remember that with great power comes great responsibility. We must use our powers wisely and responsibly, and never let our power corrupt us.

**Topic 2: The Difficulty of Writing for Superheroes**

Writing for superheroes can be challenging because they are often portrayed as invincible beings who can save the world from any threat. However, this power can also make them one-dimensional characters who are difficult to relate to or root for. As writers, we must find ways to make our superheroes relatable and human while still showcasing their power and abilities.

**Glossary:**

- Superhero: A fictional character possessing extraordinary abilities and powers, often used to save the world from evil.
- Power: The ability or capacity to do something or to possess or control a resource or ability.
- Corrupt: To cause someone to act in a wrong or immoral way.
- Absolute power: Unrestricted or uncontrolled power.

**Conclusion:**

In conclusion, the power of superheroes can be both a blessing and a curse. While they have the potential to save the world, their power can also be dangerous if not used responsibly. As we have seen with The Sentry, unchecked power can lead to great harm. Therefore, it is essential for superheroes to use their power wisely and responsibly, remembering that with great power comes great responsibility. By doing so, they can protect the world from evil while still maintaining their humanity and relatability.

Lesson: Introduction to Substance Abuse Treatment Centers

**Section 1: Theoretical Concepts**

Substance abuse is a serious issue that affects many individuals and communities. It refers to the excessive or uncontrolled use of drugs, alcohol, or other substances that cause harm to the user or others. Substance abuse treatment centers are facilities that provide care and support to individuals who are struggling with addiction. These centers offer a range of services, including detoxification, counseling, and therapy, to help individuals overcome their addictions and lead healthy, productive lives.

**Section 2: Practical Examples**

Let's consider an example of a person named John who is struggling with alcohol addiction. John has been attending alcohol rehab centers for a few weeks now, but he still finds it difficult to resist the urge to drink. One day, while at the center, John is presented with a situation where he is offered a drink. He feels tempted but remembers the coping mechanisms he learned during his treatment. He takes a deep breath, excuses himself from the situation, and calls his sponsor for support. This is just one example of how substance abuse treatment centers can help individuals overcome their addictions and learn healthy coping mechanisms.

**Section 3: Self-Debate Discussions**

Is it possible for someone with a severe addiction to recover completely? Why or why not?

Some people argue that addiction is a disease that cannot be cured completely. Others believe that with proper treatment and support, anyone can recover fully from their addiction. What do you think? Explain your reasoning.

**Glossary**

- Substance Abuse: The excessive or uncontrolled use of drugs, alcohol, or other substances that cause harm to the user or others.
- Treatment Center: A facility that provides care and support to individuals who are struggling with addiction.
- Detoxification: The process of removing toxic substances from the body.
- Counseling: A talk therapy that helps individuals understand and address their emotional and psychological challenges.
- Therapy: A type of treatment that involves activities and exercises to improve mental and emotional well-being.

**Conclusion**

Substance abuse treatment centers play a crucial role in helping individuals overcome their addictions and lead healthy lives. By understanding the theoretical concepts, applying practical examples, and engaging in self-debate discussions, we can gain a deeper understanding of the importance of these centers and the skills needed to overcome addiction.

I’ve decided to ramp up the Node.js experiments, and pass the 1 million concurrent connections milestone. It worked, using a swarm of 500 Amazon EC2 test clients, each establishing ~2000 active long-poll COMET connections to a single 15GB rackspace cloud server.

This isn’t landing the mars rover, or curing cancer. It’s just a pretty cool milestone IMO, which may help a few people who want to use Node.js for a large number of concurrent connections. So, hopefully it’s of some benefit to a few Node developers who can use these settings as a starting point in their own projects.

Here’s the connection count as displayed on the sprite’s page:

Here’s a sysctl dumping the number of open file handles (sockets are file handles):

Here’s the view of “top” showing system resources in use:

I think it’s pretty reasonable for 1M connections to consume 16GB of memory, but it could probably be trimmed down quite a bit. I haven’t spent any time optimizing that. I’ll leave that for another day.

Here’s a latency test run against the comet URL:

The new tweaks, placed in /etc/sysctl.conf (CentOS) and then reloaded with “sysctl -p” :

net.core.rmem_max = 33554432 net.core.wmem_max = 33554432 net.ipv4.tcp_rmem = 4096 16384 33554432 net.ipv4.tcp_wmem = 4096 16384 33554432 net.ipv4.tcp_mem = 786432 1048576 26777216 net.ipv4.tcp_max_tw_buckets = 360000 net.core.netdev_max_backlog = 2500 vm.min_free_kbytes = 65536 vm.swappiness = 0 net.ipv4.ip_local_port_range = 1024 65535

Other than that, the steps were identical to the steps described in my previous blog posts, except this time using Node.js version 0.8.3.

Here is the server source code, so you can get a sense of the complexity level. Each connected client is actively sending messages, for the purpose of verifying the connections are alive. I haven’t pushed that throughput yet, to see what data rate can be sent. Since the modest 16GB memory was consumed, this would have likely caused swapping and meant little. I’ll give it a shot with a higher memory server next time.

6. Conclusion

What is Node.js?
Node.js is an open-source, cross-platform runtime environment for developing server-side applications. It uses the V8 engine to execute JavaScript code beyond the confines of a web browser.

Why handle a large number of concurrent connections?
Handling a large number of concurrent connections is important because it affects the performance of your application. A slow response time can lead to frustrated users, which can result in lost business.

Setting up the environment
To set up the environment, you need to follow these steps:

1. Install Node.js: Download and install Node.js from the official website (https://nodejs.org/).
2. Create a new directory for your project: Open a terminal and create a new directory for your project using the command `mkdir node-concurrent-connections`.
3. Change directories: Navigate to the newly created directory using the command `cd node-concurrent-connections`.
4. Initialize the project: Run the command `npm init` to initialize the project.
5. Install dependencies: Run the command `npm install express` to install the Express web framework.

Optimizing the code
To optimize the code, you need to follow these steps:

1. Create a new file called `server.js`: Open a text editor and create a new file called `server.js`.
2. Add the following code to `server.js`:

```javascript
const express = require('express');
const app = express();
const port = 3000;

app.get('/', (req, res) => {
  res.send('Hello World!');
});

app.listen(port, () => {
  console.log(`Server is running at http://localhost:${port}`);
});
```

3. Create a new file called `testClient.js`: Open a text editor and create a new file called `testClient.js`.
4. Add the following code to `testClient.js`:

```javascript
const request = require('request');

for (let i = 0; i < 2000; i++) {
  const url = 'http://localhost:3000/';
  request(url, (error, response, body) => {
    if (error) {
      console.error(`Request Error: ${error}`);
    } else if (response.statusCode !== 200) {
      console.error(`Bad Response: ${response.statusCode}`);
    } else {
      console.log('Request received');
    }
  });
}
```

5. Start the server: Open a terminal and navigate to the `node-concurrent-connections` directory. Run the command `node server.js`.
6. Start the test client: Open a terminal and navigate to the `node-concurrent-connections` directory. Run the command `node testClient.js`.

Testing the code
To test the code, you can use tools like Apache Bench or JMeter to simulate a large number of concurrent users.

Conclusion
In this lesson, we learned how to handle a large number of concurrent connections using Node.js. We covered the basics of setting up the environment, optimizing the code, and testing the code. By following these steps, you can handle a large number of concurrent connections efficiently and effectively.

Protective effect of ferulic acid on nicotine-induced DNA damage and cellular changes in cultured rat peripheral blood lymphocytes: a comparison with N-acetylcysteine.
Nicotine is the major pharmacologically active substance in cigarette smoke and plays an important etiological role in the development of lung cancer. Incidence of cancer may be related to oxidative damage to host genome by nicotine. These oxidative actions may be modified by the phytochemicals present in food. The present study describes the protective effect of ferulic acid (FA), a naturally occurring nutritional compound on nicotine-induced DNA damage and cellular changes in cultured rat peripheral blood lymphocytes in comparison with N-acetylcysteine (NAC), a well-known antioxidant. One-hour exposure of lymphocytes to nicotine at the doses of 0.125, 0.25, 0.5, 1, 2, 3 and 4 mM induced a statistically significant dose-dependent increase in the levels of thiobarbituric acid reactive substances (TBARS), a lipid peroxidative marker and decrease in the levels of reduced glutathione (GSH), an important endogenous antioxidant. The lowest concentration eliciting significant damage was 1 mM nicotine and maximum damage was observed with 3 mM concentration. Hence, the test concentration was fixed at 3 mM nicotine. We have used 5 different doses of FA (10, 50, 100, 150 and 300 microM) and NAC (0.25, 0.5, 1, 2 and 4 mM) to test their protective effects. In all the groups, FA and NAC showed a dose-dependent inhibitory effect. Maximum protection was observed at the dose of 150 microM FA and 1mM NAC. So, 150 microM FA and 1mM NAC were used for further studies. There was a significant increase in the levels of lipid peroxidative index (TBARS and hydroperoxides (HP)), severity of DNA damage (evaluated by comet assay) in nicotine-treated group, which were significantly decreased in FA and NAC-treated groups. Nicotine treatment significantly decreased the endogenous antioxidant status viz., superoxide dismutase (SOD), catalase (CAT), glutathione peroxidase (GPx), GSH, vitamin A, E and C. Co-administration of FA and NAC to nicotine-treated lymphocytes showed a significant increase in the antioxidant status. The protective effect of FA was merely equal to that of NAC effect. FA and NAC treatment alone did not produce any toxicity to the normal lymphocytes at their effective doses. On the whole, there is overwhelming evidence that FA has the ability to modulate DNA damage and a variety of cellular changes that occur during nicotine-induced toxicity in rat peripheral blood lymphocytes.

Lesson: Introduction to Antioxidants and Their Role in Preventing Cancer

**Objective:** To understand the importance of antioxidants in preventing cancer and how they work.

**Key Concepts:** Antioxidants, Oxidative stress, Cancer, Ferulic Acid, N-Acetylcysteine.

**Materials:** None

**Activity:** Read the following passage carefully and answer the questions that follow.

1. What is the main idea of this passage?

2. How does nicotine contribute to the development of lung cancer?

3. What is the protective effect of ferulic acid on nicotine-induced DNA damage and cellular changes?

4. How does N-acetylcysteine compare to ferulic acid in terms of its protective effect on DNA damage?

**Answer Key:**

1. The main idea of this passage is that ferulic acid has a protective effect on nicotine-induced DNA damage and cellular changes in cultured rat peripheral blood lymphocytes compared to N-acetylcysteine.

2. Nicotine contributes to the development of lung cancer by causing oxidative damage to the host genome.

3. Ferulic acid protects against nicotine-induced DNA damage and cellular changes by reducing oxidative stress.

4. N-acetylcysteine is a well-known antioxidant, but it does not have as strong of a protective effect on DNA damage as ferulic acid.

**Discussion:**

Antioxidants are important in preventing cancer because they help to neutralize free radicals, which are unstable molecules that can cause damage to cells. When free radicals come into contact with our DNA, they can cause mutations that lead to cancer. Ferulic acid is a type of antioxidant that is found in certain foods, such as fruits and vegetables. In this study, researchers found that ferulic acid had a protective effect on nicotine-induced DNA damage and cellular changes in cultured rat peripheral blood lymphocytes compared to N-acetylcysteine, a well-known antioxidant. This suggests that ferulic acid may be more effective in preventing cancer caused by oxidative stress.

**Conclusion:**

In conclusion, we learned about the importance of antioxidants in preventing cancer and how they work. We also learned about the protective effect of ferulic acid on nicotine-induced DNA damage and cellular changes compared to N-acetylcysteine. This information is important because it can help us make informed decisions about our diet and lifestyle choices to reduce our risk of developing cancer.

**Glossary:**

- Antioxidants: Chemical compounds that inhibit the oxidation of other molecules
- Oxidative stress: A condition in which the body has an excess of free radicals that can cause cellular damage
- Cancer: A group of diseases characterized by the uncontrolled growth and spread of abnormal cells
- Ferulic acid: A naturally occurring nutritional compound found in certain foods
- N-Acetylcysteine: A well-known antioxidant used in medical treatments
