Q:

Questions on the basics of database design

I'm playing around with Sqlite3 in an attempt to get a handle on this SQL stuff. I've got a few questions on the topic.
Is there a basic structure that databases follow? I'm curious if I would model my database as though it were along the lines of a giant dictionary.
The problem I was thinking about:
If I wanted to have a program that could pull up the zip code or other general info for any city, I was thinking of a nested table kind of structure. Namely:
Countries Table:
+----+--------+--------+---------+
| US | Canada | Mexico |  Etc... |
+----+--------+--------+---------+
  |
  |
  |
  |
  | States Table:
  +---------+----------+---------+--------+
  | Alabama | Arkansas | Georgia | Etc... |
  +---------+----------+---------+--------+
                  |
                  |
                  |
                  |
                  | Cities Table:
                +-----------+---------+--------+---------+
                | Alexander | Bauxite | Benton | Etc ... |
                +-----------+---------+--------+---------+
                                           |
                                           |
                     +-----+------------+---------+------+--------------------+
                     | Key | population | zipcode | size | other random stuff |
                     +-----+------------+---------+------+--------------------+

But is that too much nesting..? Is that a bad design? The tip top stuff, the countries table doesn't really do much, and I kind of had it in my head that you were supposed to be able to do really complex things easily with a database. If I went with my design, it seems like I'd be looping over a bunch of stuff before I finally got to what I wanted. So, I'm just curious if I'm going about this entire thing incorrectly.
Does anyone know of a good primer on the basics of using a database?

A:

Relational Databases are based on the Entity-Relationship Model. If you want to grasp the concept behind RDBSMs, consider familiarizing with that theory first. Specifically relational schemes (tables, columns,relationships through foreign keys, ...) are an (or the) application of the ERM.
Another keyword to search for is Normalization. There are different "grades" of normalization and rules to transform from one grade to another, that topic is directly related to your question about the table structure. A general answer is, it depends. In general Normalization helps keeping data consistent - but a fully normalized table structure may incur a performance penalty (e.g. many joins for often used queries).
I would suggest to first go with a stricter normalization and then check the performance. Selective denormalization may then help upping the performance.

source: minipile

textbook:
Sure, I can help you with that! Here are some basic concepts and principles of database design that you might find useful:
1. Data Modeling: A database is a collection of related information that is organized and managed so that it can be accessed, updated, and shared easily. To create a good database, you need to start with a solid data model. This involves identifying the entities (or things) that you want to store data about, and then defining their relationships to each other. For example, in your case, the entities might be countries, states, and cities.
2. Normalization: Once you have identified the entities and their relationships, you need to decide how to organize the data in the database. Normalization is a process of organizing data to minimize redundancy and dependency. In other words, you want to avoid storing the same information in multiple places, and you want to make sure that changes in one place don't affect other places. There are different levels of normalization, but for most applications, third normal form (3NF) is sufficient.
3. Relational Databases: One of the most common types of databases is the relational database. In a relational database, data is stored in tables, which consist of rows and columns. Each row represents a record, and each column represents a field or attribute. You can use SQL (Structured Query Language) to query the database and retrieve specific information. For example, you might use SQL to select all the cities in a certain state.
4. SQL Basics: SQL is the language used to interact with relational databases. Here are some basic concepts you should know:
- SELECT: used to retrieve data from one or more tables
- FROM: used to specify the table(s) to retrieve data from
- WHERE: used to specify conditions that must be met for a record to be included in the result set
- GROUP BY: used to group records together based on a common attribute
- ORDER BY: used to sort the result set based on a specified attribute
- LIMIT: used to limit the number of records returned by the query
5. Practice: Like any skill, learning SQL takes practice. Try writing simple queries to retrieve data from a table, and then gradually build more complex queries. You can also use online resources like W3Schools or Codecademy to learn more advanced concepts.
I hope this helps! Let me know if you have any other questions.

When they found themselves in the woods, alone and tempted, she fought the feeling…but it was pointless. The allure of the man was just too strong. So she was going to ride the wave of passion this captivating man offered, and ignore the consequences until she had to go back to her own world.. Zoran couldn’t believe the beauty that he found in the woods. Normally, his one-week respite from his official responsibilities as Prince of Larcatia was a time of isolation and contemplation. Now his only contemplation was how to get to know the lovely wood nymph better. And isolation was the furthest thing from his mind.. So when their time together was over, it was shocking to find out that they were actually both royalty in neighboring countries! And even more unbelievable, that they were both obligated to marry someone else! To hell with royal obligations! Zoran would make Ciara his wife.. keyboard_arrow_up

# Lesson 1: Introduction to Royal Love

In this lesson, we will learn about the love story between Zoran, the Prince of Larcatia, and Ciara, a wood nymph. We will explore how they met, their struggles, and how they eventually found love despite their royal obligations.

## Section 1: The Meeting

Zoran was on a week-long retreat in the woods when he stumbled upon Ciara. He was immediately drawn to her beauty and grace. Ciara, on the other hand, was hesitant to engage with Zoran because of her fear of getting involved with someone from the outside world.

## Section 2: The Attraction

Despite Ciara's initial hesitation, Zoran's charm and charisma won her over. They spent several days together in the woods, exploring each other's company and growing closer. However, they both knew that their time together was limited and that they would eventually have to go back to their own worlds.

## Section 3: The Consequences

When Zoran and Ciara realized that they were both royalty in neighboring countries, they knew that their love would face many obstacles. They were both obligated to marry someone else, and their families might not approve of their union. Despite these challenges, they decided to pursue their love and make a life together.

## Section 4: The Decision

Zoran made it clear to Ciara that he would defy his family's expectations and make her his wife. Ciara, in turn, was willing to give up her position as a wood nymph to be with him. They knew that their love was worth fighting for, and they were willing to do whatever it took to be together.

## Glossary
- Wood Nymph: A mythical creature that lives in the woods and is known for its beauty and grace.
- Royal Obligations: The duties and responsibilities that members of royal families are expected to fulfill.

## Conclusion

In this lesson, we learned about the love story between Zoran and Ciara, two individuals who found love in unexpected places. Despite their royal obligations and the challenges they faced, they were willing to fight for their love. This story teaches us that true love can overcome all obstacles and that sometimes, we need to take risks to find happiness.

Q:

Storing persistent data in browser

For my web application, I need to store form inputs spanning across multiple pages, until I finally process/manipulate them to produce some results (its mostly formatting the data entered and presenting it in some layout). The options I think I have are -

Keep sending user's inputs to the server, store it there in some database, do the final manipulation there only, and show the result.
Store the inputs in browser's storage as the user fills the forms, and finally use this stored data to manipulate and show results.

I very much want to use the second method, and perhaps a possible way is using cookies, but I'm afraid I might just hit some upper limit of cookie data storage. I'm also open to understanding the merits of the first method, or any third method.
thanks.

A:

Use webstorage (you can client-side store around 5MB of text or binary data)
Firefox demo: http://codebase.es/test/webstorage.html
DOM Storage is supported in these web browsers:

Internet Explorer 8
Firefox 2 for sessionStorage, 3.5 for localStorage
Safari 4

Just google for sessionStorage and localStorage objects.
Also modern webkit browsers supports client-side sql.
Edit:
I'm not sure about what you want to do but using AJAX you can store everything in javascript variables and serverside databases or sessions are a good choice.

A:

Hitting the storage limit of the cookie could indicate you are trying to store too much on the client side. It might be prudent to store it serverside, in something like a session. The key to the session could then be stored in a cookie.
An alternative method is to not have the requests span multiple pages, and just store the data on the client side, not as a cookie, but as different form fields and/or text fields (they could be hidden). The merit of such a method is it doesnt hit the cookie limit as you have. It also makes your serverside code easier/cleaner, since it doesn't have to keep track of state (something you'd always have to do if spanning across pages, and thus the reason you are hitting the cookie limit in the first place).

textbook:
Lesson: Storing Persistent Data in Browser

Introduction:

In this lesson, we will learn about storing persistent data in the browser. We will explore the different methods available, their advantages and disadvantages, and when to use them. By the end of this lesson, you will be able to choose the best method for your web application and implement it effectively.

Method 1: Cookies

Cookies are small pieces of data that are sent from the server to the browser and then back to the server again. They are commonly used to store information such as user preferences, session IDs, and other data that needs to be remembered between page loads.

Advantages:
- Cookies are easy to set up and use.
- They work well with servers that support cookies.

Disadvantages:
- The maximum size of a cookie is 4KB, which may not be enough for larger amounts of data.
- Cookies can be deleted by the user or blocked by the browser, which means that the data may not be available when needed.

When to use:
- Use cookies when you need to store small amounts of data that need to be remembered between page loads.

Method 2: WebStorage

WebStorage is a newer technology that allows you to store data on the client side. It is supported by most modern browsers and provides a more robust solution than cookies.

Advantages:
- WebStorage can store larger amounts of data (up to 5MB) than cookies.
- It is more secure than cookies, as it is not sent over the wire with each request.

Disadvantages:
- Not all browsers support WebStorage.
- The data is stored locally on the user's machine, which means that it may not be available if they switch devices.

When to use:
- Use WebStorage when you need to store larger amounts of data that needs to be remembered between page loads.

Conclusion:

In conclusion, there are several methods available for storing persistent data in the browser. The choice of method depends on the amount of data you need to store, the compatibility with your target audience's browsers, and the security requirements of your application. By understanding the advantages and disadvantages of each method, you can make an informed decision and implement the best solution for your web application.

Glossary:
- Cookies: Small pieces of data sent from the server to the browser and back again.
- WebStorage: A newer technology that allows you to store data on the client side.
- Persistent data: Data that needs to be remembered between page loads.


text: Internal Variables in Thermoelasticity (Solid Mechanics and Its Applications). Arkadi Berezovski, Peter Ván. 下單後立即進貨 (1週~2週). 商品描述. This book describes an effective method for modeling advanced materials like polymers, composite materials and biomaterials, which are, as a rule, inhomogeneous. The thermoelastic theory with internal variables presented here provides a general framework for predicting a material’s reaction to external loading. The basic physical principles provide the primary theoretical information, including the evolution equations of the internal variables.. The cornerstones of this framework are the material representation of continuum mechanics, a weak nonlocality, a non-zero extra entropy flux, and a consecutive employment of the dissipation inequality. Examples of thermoelastic phenomena are provided, accompanied by detailed procedures demonstrating how to simulate them.

Thermoelasticity is a branch of solid mechanics that deals with the coupling of heat conduction and mechanical stress in materials. It is used to study the behavior of advanced materials such as polymers, composite materials, and biomaterials. These materials are often inhomogeneous, making it necessary to develop an effective model to predict their response to external loading.

In this lesson, we will explore the thermoelastic theory with internal variables, which provides a general framework for modeling advanced materials. We will cover the following topics:

1. Basic physical principles
2. Evolution equations of internal variables
3. Material representation
4. Weak nonlocality
5. Non-zero extra entropy flux
6. Consecutive employment of dissipation inequality
7. Examples of thermoelastic phenomena
8. Detailed procedures for simulating thermoelastic phenomena

### Basic Physical Principles
The basic physical principles of thermoelasticity are derived from the conservation of mass, momentum, and energy. These principles state that:

1. Mass conservation: The mass of a material remains constant over time.
2. Momentum conservation: The momentum of a material remains constant over time.
3. Energy conservation: The total energy of a material remains constant over time.

These principles are used to derive the governing equations of thermoelasticity, which describe the relationship between temperature, stress, and strain in a material.

### Evolution Equations of Internal Variables
The evolution equations of internal variables are derived from the conservation laws of mass, momentum, and energy. These equations describe how the internal variables (such as temperature, stress, and strain) evolve over time in response to external loading.

The evolution equations can be written in the form:

∂u/∂t + v ∂u/∂x = F(u, x, t)

where u represents the internal variables, v is the velocity of the material, F(u, x, t) is the external force acting on the material, and t is time.

### Material Representation
The material representation is a key component of the thermoelastic theory with internal variables. It describes how the material's properties (such as density, thermal conductivity, and elastic modulus) vary with temperature and stress.

The material representation can be written in the form:

C(T, σ, ε) = D(T, σ, ε) + E(T, σ, ε)

where C(T, σ, ε) is the constitutive equation, D(T, σ, ε) is the dissipation inequality, and E(T, σ, ε) is the entropy flux.

### Weak Nonlocality
Weak nonlocality refers to the fact that the material's response to external loading depends on its history. This means that the material's properties change over time, depending on the forces and temperatures it has experienced in the past.

The weak nonlocality can be described by the following equation:

∂C/∂t + v ∂C/∂x = 0

This equation states that the material's properties change over time, depending on the forces and temperatures it has experienced in the past.

### Non-Zero Extra Entropy Flux
The non-zero extra entropy flux is a key concept in thermoelasticity, as it describes how the material's entropy changes in response to external loading. The entropy flux can be written in the form:

q = -E(T, σ, ε)

where q is the entropy flux and E(T, σ, ε) is the entropy production rate.

### Consecutive Employment of Dissipation Inequality
The consecutive employment of the dissipation inequality ensures that the material's response to external loading is always dissipative. This means that the material's energy is always flowing in one direction, either towards or away from the material.

The dissipation inequality can be written in the form:

D(T, σ, ε) ≥ 0

where D(T, σ, ε) is the dissipation function.

### Examples of Thermoelastic Phenomena
Examples of thermoelastic phenomena include the contraction of a material due to heating, the expansion of a material due to cooling, and the warping of a material due to temperature gradients. These phenomena can be modeled using the thermoelastic theory with internal variables, by solving the governing equations and applying the material representation, weak nonlocality, non-zero extra entropy flux, and consecutive employment of dissipation inequality.

### Detailed Procedures for Simulating Thermoelastic Phenomena
To simulate thermoelastic phenomena, one must first derive the governing equations from the conservation laws of mass, momentum, and energy. Next, one must apply the material representation, weak nonlocality, non-zero extra entropy flux, and consecutive employment of dissipation inequality to the governing equations. Finally, one must solve the resulting partial differential equations using numerical methods, such as finite difference or finite element methods.

### Conclusion
In this lesson, we have explored the thermoelastic theory with internal variables, which provides a general framework for modeling advanced materials like polymers, composite materials, and biomaterials. We have covered the basic physical principles, evolution equations of internal variables, material representation, weak nonlocality, non-zero extra entropy flux, and consecutive employment of dissipation inequality. We have also provided examples of thermoelastic phenomena and detailed procedures for simulating these phenomena. By understanding these concepts, one can apply them to new problems and develop innovative solutions for modeling advanced materials.

## Lesson: Introduction to Programming Languages
### Section 1: What is a Programming Language?
A programming language is a set of instructions, commands, and syntax used to create software programs, websites, mobile apps, and other digital technologies. It is a tool that allows developers to write code, which is a set of step-by-step instructions that a computer can understand and execute.
### Questions and Answers:
Q: Why do we need programming languages?
A: Programming languages are essential because they allow us to communicate with computers and automate tasks that would otherwise be done manually. They enable us to create complex software systems, websites, and mobile applications that can perform tasks faster and more efficiently than humans.
Q: What are some common programming languages?
A: Some common programming languages include Python, Java, C++, and JavaScript.
### Definitions:
- Syntax: The set of rules that define the structure and grammar of a programming language.
- Instructions: A set of steps that a computer can follow to perform a task.
- Command: A specific instruction that tells a computer to perform an action.
- Code: A sequence of instructions written in a programming language.

Let's take a simple example. Suppose you want to create a program that adds two numbers together. Here's some code in Python that does that:
```
num1 = 5
num2 = 7
sum = num1 + num2
print("The sum of", num1, "and", num2, "is", sum)
```
In this code, we first define two variables `num1` and `num2` and assign them values. Then we add those values together and store the result in another variable called `sum`. Finally, we print out a message that tells the user what the program did.
### Section 2: Types of Programming Languages
There are several types of programming languages, including:
- Low-level languages: These are the closest to the machine code that computers can understand. They require a lot of technical knowledge to use effectively.
- High-level languages: These are easier to use and understand, since they are closer to human language. They provide more abstraction and automate many of the details that low-level languages require programmers to handle manually.
- Object-oriented languages: These are designed to support object-oriented programming, a popular approach to software development that organizes code around objects and their interactions.
- Functional languages: These are designed to support functional programming, an approach that emphasizes the use of functions and avoids state and mutable data.
### Section 3: Learning to Program
Learning to program can be challenging, but it's also a lot of fun! Here are some tips to help you get started:
- Start with a beginner-friendly language like Python or JavaScript.
- Find a tutorial or course that suits your learning style and schedule.
- Practice writing code every day.
- Join a community of programmers for support and advice.

Lesson: The Art of Magic
Introduction:
Magic is an ancient art form that has captivated audiences for centuries. It involves creating illusions and tricks that leave people in awe. In this lesson, we will explore the art of magic and learn about its history, techniques, and applications.
Section 1: History of Magic
Magic has been practiced for thousands of years. Ancient civilizations like Egypt, Greece, and China had their own forms of magic. However, modern magic as we know it today started in the 18th century with the rise of stage magicians like David Devant and Harry Houdini. These magicians used sleight of hand, misdirection, and other techniques to create illusions that amazed audiences.
Section 2: Techniques of Magic
Magicians use a variety of techniques to create their illusions. Some of these techniques include:
- Sleight of hand: This is the ability to manipulate objects using your hands. Magicians use sleight of hand to make things disappear, reappear, or change shape.
- Misdirection: This is the act of directing someone's attention away from what is really happening. Magicians use misdirection to distract their audience from seeing how they are performing a trick.

Surgery of lung metastases in renal cell carcinoma.
To examine the impact on survival of pulmonary resection in the treatment of renal cell carcinoma that has metastasized to the lung. From June 1986 to July 1991, 19 patients were submitted to synchronous or asynchronous lung metastasectomy. Histological examination confirmed the presence of lung metastases from renal cell carcinoma in 16 cases (six synchronous and 10 asynchronous with a mean disease-free interval of 23 months). In the other three cases, histological examination revealed tuberculomas, chondroid hamartoma and foci of anthracosis. To date, among the six patients with synchronous lung metastases, three have died, two are progressing and one has no evident disease after a mean survival of 24 months. Among the 10 patients who underwent surgical resection of metachronous lung metastases, one has died, three are progressing and six have no evident disease (mean survival time, 43 months). While the presence of synchronous lung metastases is an unfavourable prognostic factor even after surgical removal (five out of six patients died or are in progression shortly after metastasectomy), the results after surgery of asynchronous lung metastases are encouraging, although the real efficacy of this treatment is still to be confirmed.

Lesson: Introduction to Surgery of Lung Metastases in Renal Cell Carcinoma

### Section 1: Theoretical Concepts

In this lesson, we will learn about the surgical removal of lung metastases in renal cell carcinoma. We will discuss the importance of early detection and treatment of lung metastases, the role of surgery in managing renal cell carcinoma, and the potential benefits and risks associated with this procedure.

### Section 2: Practical Examples and Real-World Scenarios

Let's consider a hypothetical patient with renal cell carcinoma that has metastasized to the lung. The patient is scheduled for surgery to remove the lung metastasis. During the operation, the surgeon carefully removes the tumor while preserving as much healthy lung tissue as possible. After the surgery, the patient is monitored closely for any signs of complications or recurrence of the cancer.

### Section 3: Self-Debating Discussions

One debate surrounding the surgical removal of lung metastases in renal cell carcinoma is whether it is worth the risk for patients with limited life expectancy. Some argue that the potential benefits of the surgery may not outweigh the risks for patients who are unlikely to survive long-term, while others believe that every effort should be made to extend the lives of these patients, even if only for a short period of time.

### Glossary

- **Lung metastases**: cancerous cells that have spread from the original tumor in the kidney to the lung.
- **Renal cell carcinoma**: a type of kidney cancer that originates in the renal cortex, the outer part of the kidney.
- **Metachronous**: occurring at a later time than another event or condition.
- **Synchronous**: occurring at the same time or in conjunction with another event or condition.

### Conclusion

In conclusion, the surgical removal of lung metastases in renal cell carcinoma can be an effective treatment option for select patients. However, it is essential to carefully consider the potential benefits and risks associated with this procedure. By understanding the theoretical concepts, analyzing practical examples and real-world scenarios, and engaging in self-debating discussions, we can develop a deeper understanding of the role of surgery in managing renal cell carcinoma with lung metastases.

Cell aggregation and apoptosis induced by hemodialysis membranes.
During hemodialysis, circulating mononuclear cells can be stimulated to different degrees, depending on membrane biocompatibility. Cell activation usually leads to aggregation and proliferation. It may also result in apoptosis if cells are subjected to abnormal activation. This may be the case of cells exposed to bioincompatible hemodialysis membranes. The study presented here evaluates the effects of two hemodialysis membranes, with different degrees of biocompatibility, (Cuprophan (CU; Lundia IC 5N; GAMBRO, Sweden) and polyacrylonitrile (AN69; Biospal 3000S, Hospal, France)) on aggregation and apoptosis of circulating human mononuclear cells and the human mononuclear cell line (THP-1). The results showed that 2-h incubation with CU, a bioincompatible membrane, produces cell aggregation of both peripheral mononuclear cells and THP-1 cells (35% and 54%, respectively). After 48 h of incubation with a CU membrane, apoptotic death was observed in 32% of THP-1 cells and in 45% of normal peripheral mononuclear cells. Neither cell aggregation nor apoptosis was observed after incubation with the AN69 membrane. CU membrane-induced apoptosis was inhibited by Staurosporrin (Sigma, St. Louis, MO) a protein kinase C (PKC)-inhibitor, suggesting that cell apoptosis induced by the CU membrane is mediated by a PKC-dependent cell activation. Furthermore, cell prestimulation with phorbol 12-myristate 13-acetate, an activator of PKC, results in a increase in the percentage of THP-1 cell death by apoptosis after CU exposure (53%). Our study indicates that CU membranes induce mononuclear cell activation, leading to cell apoptosis.

Lesson: The Effects of Hemodialysis Membranes on Cell Aggregation and Apoptosis

Introduction:
Hemodialysis is a common treatment for patients with kidney failure. During this process, blood is filtered through a dialyzer, which contains a special membrane that separates waste products and excess fluids from the blood. The choice of membrane used in hemodialysis can have significant effects on the health of circulating mononuclear cells. In this lesson, we will explore the impact of two different hemodialysis membranes, Cuprophan (CU) and polyacrylonitrile (AN69), on cell aggregation and apoptosis of human mononuclear cells.

Objectives:
- Understand the effects of hemodialysis membranes on cell aggregation and apoptosis
- Identify the differences between cell aggregation and apoptosis
- Analyze the results of experiments conducted to evaluate the effects of CU and AN69 membranes on human mononuclear cells

Section 1: Cell Aggregation and Apoptosis

Cell aggregation refers to the process where cells group together and form clusters. This can occur when cells are activated by certain stimuli, such as exposure to a hemodialysis membrane. Apoptosis, on the other hand, is a form of programmed cell death that occurs when cells are subjected to abnormal activation or damage. Both cell aggregation and apoptosis can have significant effects on overall health, so understanding their causes and consequences is essential.

Section 2: Experimental Results

The study presented here evaluated the effects of CU and AN69 membranes on cell aggregation and apoptosis of human mononuclear cells. The results showed that 2-hour incubation with CU, a bioincompatible membrane, produced cell aggregation of both peripheral mononuclear cells and THP-1 cells (35% and 54%, respectively). After 48 hours of incubation with a CU membrane, apoptotic death was observed in 32% of THP-1 cells and in 45% of normal peripheral mononuclear cells. In contrast, neither cell aggregation nor apoptosis was observed after incubation with the AN69 membrane.

Section 3: Conclusion

In conclusion, the choice of hemodialysis membrane can have significant effects on the health of circulating mononuclear cells. The CU membrane, which is bioincompatible, caused cell aggregation and apoptosis in both peripheral mononuclear cells and THP-1 cells. In contrast, the AN69 membrane did not cause these effects. Understanding the impact of hemodialysis membranes on cell aggregation and apoptosis can help researchers and clinicians make informed decisions about the best treatment options for patients with kidney failure.

Glossary:
- Cell aggregation: The process where cells group together and form clusters
- Apoptosis: A form of programmed cell death that occurs when cells are subjected to abnormal activation or damage
- Hemodialysis: A treatment for patients with kidney failure that filters blood through a special membrane
- Dialyzer: The device used in hemodialysis to separate waste products and excess fluids from the blood

Self-Debate Discussion:

Is it necessary to use hemodialysis membranes that cause cell aggregation and apoptosis in circulating mononuclear cells? Should more research be done to develop biocompatible membranes that do not have these effects?

Lesson: Introduction to Cycling Teams

## Section 1: Theoretical Concepts

A cycling team is a group of cyclists who compete together in races and events. They are sponsored by companies or organizations that provide funding, equipment, and support. These teams are often composed of riders with different skill sets and roles, such as sprinters, climbers, time trial specialists, and domestiques.

## Section 2: Practical Examples

Let's consider a hypothetical cycling team called "Team Blue." Team Blue is sponsored by a blue energy drink company and consists of five riders: a sprinter, a climber, a time trial specialist, a domestique, and a team leader. The sprinter is fast and can win races in bunch sprints, while the climber excels at uphill finishes. The time trial specialist is great at individual time trials, and the domestique supports the team leader in races.

In a race, the team strategizes to set up the team leader for a sprint finish. The sprinter and domestique work together to keep the pace high and prevent any breakaways from forming. The climber and time trial specialist provide support by blocking wind and maintaining a steady pace. In the end, the team leader wins the race, thanks to the perfect setup by the rest of the team.

## Section 3: Real-World Scenarios

One famous example of a successful cycling team is the Tour de France-winning Team Sky, now known as Team Ineos. This team has won the Tour de France multiple times and has launched the careers of many successful cyclists, including Chris Froome and Geraint Thomas.

## Glossary
- Cycling team: A group of cyclists who compete together in races and events, sponsored by companies or organizations.
- Sponsor: A company or organization that provides funding, equipment, and support for a cycling team.
- Roles: Different skill sets and positions within a cycling team, such as sprinters, climbers, time trial specialists, and domestiques.
- Strategize: Plan and prepare for a race or event.
- Breakaway: A small group of riders that breaks away from the main peloton.

## Conclusion

Cycling teams are an essential part of the sport of cycling. They provide a platform for riders to compete together, share resources, and work towards a common goal. By understanding the different roles within a team and how they work together, we can better appreciate the complexity and strategy involved in cycling races.

>The app _its_ [sic] only 129MB in size and you can download it over at Github
for both macOS and Windows. Once it’s running it surprisingly only takes up
around 200MB of RAM, even when running all of the old Windows 95 system
utilities, apps, and games.

Only to give some perspective, the original requirements for Windows 95 were:

1) 4MB of memory (8MB recommended)

2) 50-70 MB space on hard disk

so IMHO the "surprisingly only takes" comment is _surprising_.

I ran Windows 95 under 8MB and let me tell you, that was far from sufficient!
There was a RAM shortage back in those days so getting the second 8MB SIMM was
a fairly expensive proposition for a teenager. Also on a 85Mb hard drive too
don’t get me started ...

Sure, you take the "recommended" (which is usually double the minimum) and at
least double it to have a minimally running system and quadruple it too have
it running decently, this is "standard Microsoft".

Lesson: Introduction to Computer History and Operating Systems

## Chapter 1: Introduction

In this lesson, we will learn about the history of computer operating systems, starting with the first ones developed in the 1950s and ending with the modern-day Windows, Mac OS, and Linux. We will also explore how these operating systems have evolved over time and what they do for us.

## Chapter 2: Early Operating Systems

The first operating systems were developed in the 1950s for mainframe computers. These early operating systems were designed to manage computer resources and provide a way for users to interact with the computer. One of the earliest operating systems was IBM's OS/360, which was introduced in 1964.

## Chapter 3: Time-sharing and Multitasking

As computers became more powerful, operating systems began to include features that allowed multiple users to access the same computer at the same time. This was known as time-sharing. Multitasking, or the ability to run multiple programs at once, was also introduced. These features allowed users to share resources like printers and disks without having to wait for each other's turns.

## Chapter 4: Graphical User Interfaces

In the 1980s, operating systems began to include graphical user interfaces (GUIs). These allowed users to interact with the computer using icons, menus, and windows instead of text-based commands. The introduction of the Macintosh in 1984 popularized the GUI, and Microsoft soon followed with Windows 1.0 in 1985.

## Chapter 5: Modern Operating Systems

Today, there are many different types of operating systems. Some are designed for personal computers, while others are designed for mobile devices or servers. Modern operating systems include features like virtual memory, network protocols, and security measures. They also support a wide range of hardware devices, from printers and scanners to cameras and microphones.

## Chapter 6: Conclusion

Operating systems are essential for modern computing. They manage computer resources, provide a way for users to interact with the computer, and support a wide range of hardware devices. Over time, operating systems have evolved from simple command-line interfaces to sophisticated graphical user interfaces. Today, there are many different types of operating systems, each designed for specific purposes. As technology continues to advance, we can expect operating systems to become even more advanced and feature-rich.
