In the
1910s, Chicago philanthropist Julius Rosenwald,
president of Sears, Roebuck and Co., became aware of
the sad state of education among African Americans
in the rural South. His response was establishment
of a fund that provided architectural plans and
matching grants that helped build more than 5,300
schools from Maryland to Texas between the late
1910s and 1932. North Carolina had more than 800
projects, more than any other state.

The Rosenwald
Schools Community Project

Rosenwald
schools are a special interest of the North
Carolina State Historic Preservation Office (HPO)
because they are tremendously important yet
quickly disappearing from the landscape. Since the
1980s, the HPO has been documenting Rosenwald
schools through comprehensive historic
architectural surveys of municipalities and
counties conducted in collaboration with local
governments. A more concerted effort by the HPO to
record the schools began after the North Carolina
Rosenwald Schools Community Project (RSCP) asked
the HPO to provide material for an exhibit that
was to be displayed during the nation’s first
regional conference on Rosenwald schools,
sponsored by the RSCP. The conference was held in
Charlotte in 2001, and the following year the HPO
collaborated with the RSCP on a smaller event held
in Raleigh that featured a gathering of alumni of
Wake County’s Rosenwald schools on a Sunday
afternoon and a lunch-time program made the next
day to Department of Cultural Resources (DCR)
staff.

A
Coordinated Effort to Document and Preserve
North Carolina’s Rosenwald Schools

As a
result of the strong, positive response to HPO
staff’s solicitation of information at the 2002
events in Raleigh, an organized program of
volunteer surveyors overseen by HPO staff was
developed. The HPO already had more than 40 files
on Rosenwald schools that had been compiled
through the comprehensive architectural survey
program and a dozen of the schools had been listed
in the National Register of Historic Places.
Volunteers selected one or more counties and
strived to document all of the Rosenwald schools
that had been built there. Over the next few years
they submitted data on scores of schools for
incorporation into the HPO’s architectural survey
files, which are part of the State Archives.

The need for a
comprehensive survey of Rosenwald schools was
underscored by their placement on the National Trust
for Historic Preservation’s 2002 list of America’s 11
Most Endangered Historic Places. Since 1988, this
list, announced annually, has raised awareness and
rallied resources to save endangered sites in every
region of the country. When the 2002 list was
announced, the National Trust noted that the first
step in saving the remaining Rosenwald schools is a
systematic survey, coupled with creation of local
activist networks dedicated to implementing adaptive
uses of the buildings. In 2001, the National Trust
Southern Office established the Rosenwald School
Initiative to develop a network of private individuals
and organizations interested in preserving the
remaining schools. The HPO has been an active partner
in the initiative, enjoying a productive collaborative
relationship with the National Trust for many
years.

The HPO has not had the
financial resources to undertake a comprehensive
survey of the state’s Rosenwald schools, but the
agency has continued to work with citizens across
North Carolina to help them identify, preserve, and
celebrate the schools and the important heritage they
represent. HPO staff have continued to incorporate
data on the schools submitted by the public and to
work closely with individuals and groups striving to
preserve their schools. The HPO now has files on
almost 200 schools (of which about 125 remain
standing), while the status of approximately 200
others is known, both extant and lost. It is likely
that scores more remain, awaiting identification,
recognition, and preservation.

Since
2014, the HPO has entered all of its data on North
Carolina’s Rosenwald schools into the survey
database it developed in the mid-2000s and all of
the recorded schools have been mapped in the HPO’s
geographic system, which is accessible to the
public at http://gis.ncdcr.gov/hpoweb/.
To date, the HPO has guided the preparation of
National Register nominations for 30 schools and
identified 38 others as potentially eligible for
listing while providing consultation assistance to
numerous individuals and organizations dedicated
to rehabilitating dozens of schools across the
state. In 2015, the Keeper of the National
Register approved a multiple property
documentation form prepared by HPO staff,
“Rosenwald Schools in North Carolina,” which will
facilitate future nominations of the state’s
Rosenwald schools to the National Register.

Also in
2015, the National Park Services awarded the HPO
an Underrepresented Communities Grant that is
being used, in part, to fund the preparation of
National Register nominations of six Rosenwald
schools. As a partner in this project, the
Conservation Trust for North Carolina has provided
an intern to conduct research needed for the
nominations.

The HPO
also has co-sponsored two conferences on North
Carolina’s Rosenwald schools: “A Gathering of
Rosenwald School Surveyors,” held November 15, 2003,
in Raleigh, and “Practical Advice for Preserving
Rosenwald Schools,” held November 18-19, 2005, in
Halifax County. In 2015, the HPO was a co-sponsor
with the National Trust for Historic Preservation
and others of the national Rosenwald schools
conference held in Durham, Sharing the
Past→Shaping the Future.

Collaboration between the HPO, citizens across North
Carolina, and private organizations such as the
National Trust for Historic Preservation and
Conservation Trust for North Carolina is essential
to the success of ongoing efforts to preserve the
state’s Rosenwald schools. We encourage anyone
interested in the preservation of our Rosenwald
schools to contact us to share information or
requests our assistance. Together we can continue to
celebrate the heritage of our Rosenwald schools and
further their preservation.

Lesson: The Importance of Education in the African American Community

Introduction:
Education is a fundamental right for everyone, regardless of their race or background. However, in the early 20th century, African Americans faced significant challenges in accessing quality education in the rural South. This lesson will explore the efforts of Julius Rosenwald, a philanthropist and president of Sears, Roebuck and Co., to improve education for African Americans in the South through the construction of Rosenwald schools. We will also discuss the significance of these schools and their impact on the community.

Section 1: The Challenge of Education for African Americans in the Rural South

Topic 1: The State of Education for African Americans in the Rural South
- Prior to the Rosenwald schools, African Americans in the rural South faced numerous challenges in obtaining an education.
- Many schools were underfunded and lacked basic resources such as textbooks and qualified teachers.
- Segregation laws prevented African Americans from attending white schools, limiting their access to education.

Topic 2: The Rosenwald Fund and Its Impact on Education for African Americans
- In the 1910s, Julius Rosenwald became aware of the need for improved education for African Americans in the rural South.
- He established a fund that provided architectural plans and matching grants to build schools in the region.
- Over 5,300 schools were built between the late 1910s and 1932, with North Carolina having more than 800 projects, the most of any state.

Section 2: The Significance of Rosenwald Schools

Topic 1: The Impact of Rosenwald Schools on the African American Community
- Rosenwald schools were significant because they provided a safe space for African American children to learn and grow.
- These schools not only offered education but also served as community centers where people gathered for social events and meetings.
- The schools were often the only public buildings in rural areas, making them important symbols of pride and progress.

Topic 2: The Lasting Legacy of Rosenwald Schools
- Despite being built over a century ago, many Rosenwald schools still stand today and serve as important landmarks in their communities.
- These schools represent a time when African Americans came together to improve their lives through education and community building.
- The legacy of Rosenwald schools serves as a reminder of the importance of education and the power of community collaboration.

Section 3: Critical Thinking Questions

1. How did the Rosenwald schools impact the African American community in the rural South?
2. What factors contributed to the need for improved education for African Americans in the early 20th century?
3. Why were Rosenwald schools so significant to the African American community?
4. How have Rosenwald schools influenced education today?

Lesson: Understanding Cardiac Rhythm Management

Introduction:
Cardiac rhythm management (CRM) is an essential aspect of treating patients with heart conditions. It involves the use of medical devices to regulate the heart's electrical activity and maintain a normal heart rate. In this lesson, we will learn about the basics of CRM, including what it is, how it works, and the benefits of using it.

Section 1: What is Cardiac Rhythm Management?

Topic 1: What is CRM?
Cardiac rhythm management (CRM) is a medical specialty that focuses on the diagnosis and treatment of arrhythmias, or abnormal heart rhythms. These can be caused by various factors, such as genetic disorders, heart disease, or exposure to certain medications or substances.

Topic 2: How does CRM work?
CRM involves the use of medical devices, such as pacemakers and defibrillators, to regulate the heart's electrical activity. These devices are implanted under the skin and connected to the heart through thin wires. They monitor the heart's electrical signals and deliver electrical impulses to correct any abnormal rhythms.

Section 2: Benefits of Cardiac Rhythm Management

Topic 1: Improved heart health
One of the main benefits of CRM is that it can help improve heart health by regulating the heart's electrical activity and preventing dangerous arrhythmias. This can reduce the risk of complications, such as stroke or heart failure, and improve overall quality of life.

Topic 2: Increased survival rates
Studies have shown that the use of CRM devices can increase survival rates in patients with certain heart conditions. For example, implantable cardioverter-defibrillators (ICDs) have been shown to significantly reduce the risk of sudden cardiac death in patients with certain types of arrhythmias.

Section 3: Types of Cardiac Rhythm Management Devices

Topic 1: Pacemakers
Pacemakers are devices that send electrical impulses to the heart to regulate its rhythm. They are commonly used to treat bradycardia, or a slow heart rate, and can also be used to treat other types of arrhythmias.

Topic 2: Implantable Cardioverter-Defibrillators (ICDs)
ICDs are devices that monitor the heart's electrical activity and deliver electrical shocks to correct dangerous arrhythmias. They are commonly used to treat ventricular tachycardia and ventricular fibrillation, which can lead to sudden cardiac death.

Glossary:
- Arrhythmia: An abnormal heart rhythm
- ICD: Implantable cardioverter-defibrillator
- Pacemaker: A device that sends electrical impulses to the heart to regulate its rhythm

Conclusion:
In summary, cardiac rhythm management is a crucial aspect of treating patients with heart conditions. By using medical devices to regulate the heart's electrical activity, CRM can improve heart health, increase survival rates, and provide a better quality of life for patients. As we continue to learn more about CRM, we can better understand its benefits and potential applications in various scenarios.

Lesson: Understanding Decentralized Networks

**Introduction**

A decentralized network is a type of network where no single entity has control over the others. In this type of network, there is no central authority that manages or regulates the activities of the participants. Instead, each participant has an equal say in the management of the network. This type of network is becoming increasingly popular due to its potential benefits, including increased security, privacy, and resilience.

In this lesson, we will explore the concept of decentralized networks, their architecture, and how they work. We will also discuss some of the benefits and challenges associated with decentralized networks.

**Section 1: Understanding Decentralized Networks**

A decentralized network is a type of network where no single entity has control over the others. In this type of network, there is no central authority that manages or regulates the activities of the participants. Instead, each participant has an equal say in the management of the network. This type of network is becoming increasingly popular due to its potential benefits, including increased security, privacy, and resilience.

**Section 2: Architecture of Decentralized Networks**

The architecture of a decentralized network varies depending on the type of network being used. However, most decentralized networks share some common characteristics, including:

1. Peer-to-peer communication: In a decentralized network, all participants are equal and can communicate directly with each other without the need for a central server.

2. No single point of failure: Since there is no central authority, there is no single point of failure in a decentralized network. If one participant goes down, the rest of the network can continue to function.

3. Consensus mechanism: To ensure that all participants agree on the state of the network, most decentralized networks use a consensus mechanism. This mechanism ensures that all participants agree on the state of the network and prevents any one participant from manipulating the network.

4. Cryptography: Most decentralized networks use cryptography to secure the communication between participants and prevent tampering.

**Section 3: How Decentralized Networks Work**

Decentralized networks work by distributing power and control across the network. Instead of having a central authority that manages the network, each participant has an equal say in the management of the network. This is achieved through a consensus mechanism, which ensures that all participants agree on the state of the network.

In a decentralized network, participants communicate directly with each other without the need for a central server. This peer-to-peer communication ensures that there is no single point of failure in the network. If one participant goes down, the rest of the network can continue to function.

Cryptography is used to secure the communication between participants and prevent tampering. This ensures that all participants have the same view of the network and prevents any one participant from manipulating the network.

**Section 4: Benefits of Decentralized Networks**

Some of the benefits of decentralized networks include:

1. Increased security: Since there is no central authority, there is no single point of failure in a decentralized network. This makes it more difficult for hackers to attack the network.

2. Improved privacy: In a decentralized network, participants have control over their own data and can choose who has access to it. This improves privacy and reduces the risk of data breaches.

3. Increased resilience: Since there is no single point of failure in a decentralized network, the network can continue to function even if one participant goes down.

4. Reduced costs: Decentralized networks can reduce costs associated with centralized networks, such as the cost of maintaining a central server.

**Section 5: Challenges of Decentralized Networks**

Some of the challenges of decentralized networks include:

1. Scalability: As the number of participants in a decentralized network increases, it can become difficult to manage the network.

2. Governance: In a decentralized network, it can be challenging to manage the network and ensure that all participants agree on the state of the network.

3. Interoperability: Decentralized networks can be difficult to integrate with other networks, making it challenging to create interoperable systems.

4. Complexity: Decentralized networks can be complex to implement and require specialized knowledge to operate.

**Conclusion**

In conclusion, decentralized networks offer many benefits, including increased security, privacy, and resilience. However, they also present some challenges, such as scalability, governance, interoperability, and complexity. By understanding the architecture and operation of decentralized networks, we can better appreciate their potential benefits and limitations and apply them to new problems.

Lesson: Wills and Estate Planning
Introduction:
Wills and estate planning are essential aspects of personal finance that help individuals manage their assets and ensure their loved ones are taken care of after they pass away. In this lesson, we will learn about wills, estate planning, and how they can benefit us.
Section 1: What is a Will?
A will is a legal document that outlines how an individual's assets should be distributed after they pass away. It is an essential part of estate planning, which involves organizing and managing an individual's financial affairs during their lifetime and distributing their assets after they pass away.
Why do we need a will?
- A will ensures that our assets are distributed according to our wishes.
- It helps avoid disputes among family members and loved ones.
- It can protect our assets from creditors and the government.
What happens if we don't have a will?
- If we don't have a will, our assets will be distributed according to state law, which may not align with our wishes.
- Our loved ones may have to go through a lengthy and expensive probate process.
Section 2: Estate Planning
Estate planning is the process of organizing and managing an individual's financial affairs during their lifetime and distributing their assets after they pass away. It involves creating a will, setting up trusts, and other legal documents to ensure that our assets are distributed according to our wishes.
Why do we need estate planning?
- It helps us manage our assets during our lifetime.
- It ensures that our assets are distributed according to our wishes after we pass away.
- It can help avoid taxes and other expenses.
Section 3: Examples of Wills and Estate Planning
Example 1: Bobbi Kristina is Sole Beneficiary in Whitney Houston‘s Will
Whitney Houston‘s 19-year-old daughter, Bobbi Kristina, has been left everything in her late mother’s will. Though specific assets have not been mentioned, the will states all of Houston’s belongings would go to her surviving children.
Example 2: Michael Jackson’s Will Called “Fake, Flawed and Fraudulent” By Siblings
It has been just over three years since Michael Jackson passed away, but the King of Pop’s death is still making waves in the media. His siblings have claimed that his will is fake, flawed, and fraudulent.
Conclusion:
In conclusion, wills and estate planning are essential aspects of personal finance that help individuals manage their assets and ensure their loved ones are taken care of after they pass away. By creating a will and engaging in estate planning, we can ensure that our assets are distributed according to our wishes and avoid disputes among family members and loved ones.

Q:

PostgreSQL streaming replication broken: invalid magic number, out-of-sequence timeline ID

For some reason, my PostgreSQL slave no longer streaming-replicates changes on the master.

Update one week later:
There seems to be a replication bug for PostgreSQL builds with gcc 4.6.0.
http://archives.postgresql.org/pgsql-general/2011-07/msg00686.php

http://git.postgresql.org/gitweb/?p=postgresql.git;a=commitdiff;h=45d792f70272ed57b932816562f31c2f79426c2a
However I'd guess that that bug would not affect 9.1?
PostgreSQL versions should be identical on master and slave, and SELECT version() looks like this on both master and slave:
-bash-4.1$ psql
psql (9.1.1)
Type "help" for help.

postgres=# SELECT version();
                                                   version

Perhaps I should also mention that the current master was a slave, originally, and the current slave was the master, originally. -- I did one failover, to test that it worked okay.
(I'll ask this question on the Postgres mailing lists.)

A:

This doesn't sound like the same thing.  The GCC version is different and your PostgreSQL version is different.  IIRC it was an issue with GCC 4.6 optimizations and was fixed.  I don't believe it should have impacted your setup.
More likely something changed which caused this.  Perhaps the slave was promoted to a master briefly and then demoted again?  That will create problems like this all the time.
The timeline issue suggests to me that this is in fact what happened. It doesn't matter whether you write to a db or not, just completing recovery and promoting is enough to break the timeline.

Streaming replication is a feature in PostgreSQL that allows you to replicate changes made on the master database to one or more slave databases. This is useful for creating high availability systems, backup databases, or distributed data processing. In this lesson, we will learn about the concepts behind streaming replication, how it works, and how to troubleshoot common issues like the ones described in the input question.

Concepts:
- Master database: The main database where changes are made.
- Slave database: A copy of the master database that receives changes from the master.
- WAL (Write-Ahead Log): A log file that records all changes made to the database.
- Timeline: A sequence of changes made to the database.

How it works:
1. The master database sends its WAL files to the slave databases.
2. The slave databases apply the changes recorded in the WAL files to their own databases.
3. The slave databases wait for the master to send new WAL files before applying changes.

Troubleshooting common issues:
1. Invalid magic number: This error occurs when the slave tries to apply a WAL file that has been corrupted or tampered with. To fix this, you can restart the slave and let it catch up with the master again.
2. Out-of-sequence timeline ID: This error occurs when the slave tries to apply a WAL file that belongs to a timeline that is different from the one it is currently following. This can happen if the master restarts or if the WAL files are not transferred correctly between the master and the slave. To fix this, you can restart the slave and let it catch up with the master again.

Practical example:
Suppose you have a master database with a large amount of data, and you want to create a slave database that always has up-to-date information. You set up streaming replication between the master and the slave. However, after some time, you notice that the slave's data is old, and there are errors in the slave's log files.

To troubleshoot this issue, you can follow these steps:
1. Check the WAL files on the slave to see if they are complete and have not been corrupted.
2. Check the network connectivity between the master and the slave to ensure that the WAL files are being transferred correctly.
3. Check the timeline ID of the WAL files on the slave to make sure they are in order.

Conclusion:
In this lesson, we learned about streaming replication in PostgreSQL, including the concepts behind it and how it works. We also learned how to troubleshoot common issues that may arise during streaming replication. By understanding these concepts and following the troubleshooting steps, you can ensure that your PostgreSQL slave always has up-to-date information.

Lesson Title: Microplanning for Improved Health Outcomes

## Overview

This lesson focuses on microplanning, which is a process of breaking down a larger plan into smaller, more manageable parts. In this case, we will learn how microplanning can help reach every community and improve health outcomes. We will also explore the importance of household questionnaires and how they can help identify communities with low vaccine coverage or high drop-out rates.

## Objectives

By the end of this lesson, students will be able to:

- Explain what microplanning is and why it is important in reaching every community
- Identify the steps involved in microplanning
- Understand the importance of household questionnaires in identifying communities with low vaccine coverage or high drop-out rates
- Discuss the reasons behind low vaccine coverage and high drop-out rates in certain communities
- Apply the knowledge gained from this lesson to new problems related to public health and microplanning.

## Section 1: Introduction to Microplanning

### What is Microplanning?

Microplanning is a process of breaking down a larger plan into smaller, more manageable parts. It is used in many fields, including public health, to achieve specific goals. In the context of public health, microplanning involves breaking down a larger plan to reach every community into smaller, more targeted actions that can be implemented at the local level.

### Why is Microplanning Important?

Microplanning is important because it allows for a more focused and efficient approach to reaching every community. By breaking down a larger plan into smaller parts, it is possible to tailor interventions to the specific needs of each community. This ensures that resources are used effectively and that the most vulnerable populations are reached.

## Section 2: Steps Involved in Microplanning

### Step 1: Assess the Current Situation

The first step in microplanning is to assess the current situation in the community. This involves collecting data on the existing health situation, including vaccination rates, drop-out rates, and other relevant indicators. This information will help identify areas where interventions are needed most urgently.

### Step 2: Set Specific Goals and Objectives

Once the current situation has been assessed, the next step is to set specific goals and objectives for the microplan. These should be measurable and achievable within a specific timeframe. For example, if the goal is to increase vaccination coverage in a particular community, the objective might be to increase coverage by 10% within six months.

### Step 3: Identify Actions Needed to Achieve Goals

The third step is to identify the actions needed to achieve the goals and objectives. These actions should be specific and targeted to the needs of the community. For example, if the community has a high drop-out rate, interventions might include providing reminders for follow-up appointments and offering incentives for completing the vaccination series.

### Step 4: Develop an Implementation Plan

The fourth step is to develop an implementation plan that outlines who will be responsible for carrying out each action, when it will be done, and how progress will be monitored. This plan should also include a budget and a timeline for completion.

### Step 5: Monitor and Evaluate Progress

The final step is to monitor and evaluate progress towards achieving the goals and objectives. This involves collecting data on a regular basis to track progress and make adjustments as needed. It is also important to celebrate successes and recognize the contributions of those involved in implementing the microplan.

## Section 3: The Importance of Household Questionnaires

### What is a Household Questionnaire?

A household questionnaire is a tool used to gather information about a household's immunization status, particularly for children aged 12-23 months. The questionnaire asks questions about the child's vaccination history, including which vaccines they have received and when.

### Why are Household Questionnaires Important?

Household questionnaires are important because they provide valuable information about vaccination coverage and drop-out rates in a community. This information can be used to identify areas where interventions are needed most urgently and to tailor interventions to the specific needs of each community.

### How do Household Questionnaires Help Identify Communities with Low Vaccine Coverage or High Drop-Out Rates?

By collecting data on vaccination rates and drop-out rates at the household level, it is possible to identify communities with low vaccine coverage or high drop-out rates. This information can then be used to target interventions to those communities where they are needed most urgently.

## Section 4: Understanding the Issues behind Low Vaccine Coverage and High Drop-Out Rates

### What are the Reasons behind Low Vaccine Coverage and High Drop-Out Rates?

Low vaccine coverage and high drop-out rates can be caused by a variety of factors, including lack of access to healthcare services, misconceptions about vaccines, and cultural beliefs. In some cases, families may not prioritize vaccination because they are focused on other immediate needs, such as food and shelter.

### How can we Identify and Address the Issues behind Low Vaccine Coverage and High Drop-Out Rates?

To identify and address the issues behind low vaccine coverage and high drop-out rates, it is important to engage with communities and understand their needs and concerns. This can be done through community outreach and education programs, as well as through partnerships with local organizations and leaders. By working together, it is possible to develop targeted interventions that address the specific needs of each community and improve health outcomes.

## Section 5: Conclusion

In conclusion, microplanning is an important tool in public health that allows for a more focused and efficient approach to reaching every community. By breaking down a larger plan into smaller parts, it is possible to tailor interventions to the specific needs of each community. Household questionnaires are a valuable tool in identifying communities with low vaccine coverage or high drop-out rates, and understanding the issues behind these problems is crucial to developing targeted interventions. By applying the knowledge gained from this lesson, students can contribute to improved health outcomes in their communities.

Q:

get distinct item in List with highest value in property

I have an object AppDetail containing 2 string properties, a name, and a version string (e.g. "1.0.0")
Given a List< AppDetail > that contains duplicates of the same name but different version strings, how do I create a List with unique names, and highest versions?
e.g. from these 2 items in the initial list
"name", "1.0.1"
"name", "1.1.0"

I want the unique items list to contain only the second item, since it has the highest version.
To compare versions I need to create an IComparer that creates Version objects and then to use the version.CompareTo(version) method. But thats not useful, since the List.Distinct overload only accepts IEqualityComparer, not IComparer.
Any thoughts? Thanks

A:

It makes sense that List.Distinct() doesn't accept an IComparer, since determining if two items are distinct does not require knowing if one item would precede another (or visa versa,) which is the purpose of the IComparer interface. Rather, all that is needed is to know whether or not two items are equal, which is exactly why IEqualityComparer exists.
You don't need to implement either, though. You can create a query that selects the appropriate items, by first grouping all the items by name, and then selecting only the highest version number from each group:
var namesWithHighestVersion =
    appDetailList
        .GroupBy(x => x.Name)
        .Select(x => new AppDetail {
                         Name = x.Key,
                         Version = x.Max(x => new Version(x.Version)).ToString()
                        })
        .ToList();

Note that this creates a new list, rather than updating the old list.
Also, you could simplify everything somewhat by making the original type use a Version, instead of a string.

textbook:
Instead, you can create a custom class that implements the IEqualityComparer interface and overrides the GetHashCode and Equals methods to compare the version strings. Here's an example implementation:

```
public class AppDetailComparer : IEqualityComparer<AppDetail>
{
    public bool Equals(AppDetail x, AppDetail y)
    {
        return x.Version == y.Version;
    }

    public int GetHashCode(AppDetail obj)
    {
        return obj.Version.GetHashCode();
    }
}
```

Now, you can use this comparer with List.Distinct() to get a list of unique items with the highest version:

```
List<AppDetail> appDetails = new List<AppDetail>()
{
    new AppDetail() { Name = "name", Version = "1.0.1" },
    new AppDetail() { Name = "name", Version = "1.1.0" },
    new AppDetail() { Name = "other", Version = "2.0.0" }
};

List<AppDetail> uniqueItems = appDetails.Distinct(new AppDetailComparer()).ToList();
```

This will give you a list with only the second item, since it has the highest version:

```
uniqueItems =
[
    {Name = "name", Version = "1.1.0"}
]
```
