Managing User and Group Accounts

Have you ever looked at a matchmaking site? People post personal information about themselves in the hopes that they will meet someone and form a romantic connection. If you look at these personal ads, you will notice the people who post them try to make themselves look their best. They focus on the most positive and attractive aspects of their personality, their interests, and even their appearance.

This attention to positive aspects makes sense. If they are lucky, someone will be interested in their profile and ask them out on a date. When it comes to finding a job, your career portfolio—including your cover letter and resume—acts sort of like a personal ad. It is a way for employers to assess quickly how attractive you are to them in terms of your qualities as a potential employee. Do you have the skills, experience, and education employers need? A portfolio that demonstrates you have what it takes is more likely to interest employers, perhaps enough to ask you to interview. Is your portfolio ready to share? Do you have what it takes to find your career match?

This resource provides instruction for users to:

Describe the components of an effective cover letter
Identify the elements of a career portfolio
Describe the components of an effective job application

Configuring Security

Have you ever shown up to class unprepared? Perhaps you didn't make time to read your assignments or forgot your materials at home. In those situations, you most likely sat in your seat hoping the instructor didn't call on you to answer a question. Take Logan, who comes to classes unprepared a few times a semester. Though he isn't the best student, he gets by and makes just passing grades. Since this method still allows him to pass classes, Logan figures he doesn't always need to prepare ahead of time for other aspects of his life, such as job interviews. After all, Logan knows he is good at talking to new people and thinks he is a smart guy. However, after his first real interview, Logan realizes he missed the mark in quite a few areas.

You may be able to attend a class or two unprepared, but in job interviews, coming prepared is essential. You need to know what type of interview you will have, what questions the interviewer may ask, and how you will respond. Also, figure out what questions you want to ask the interviewer during the interview. Are you prepared with regard to all these aspects?

This resource provides instruction for users to:

Contrast different types of interviews
Evaluate different techniques of interview preparation
Describe useful information sources for interview preparation

• Configuring Security

Scheduling Jobs

Can you name five things you can do to really shine in an interview? What about five things you should not do? On top of knowing what you should and shouldn't do, you need to know the sorts of answers employers want to hear when they interview job candidates. The bottom line is you must be sure you can demonstrate you have what it takes, not just through what you say, but by what you do in an interview.

Whether you have never had a job interview or gone through dozens (or more!), you can always find ways to improve your interviewing skills. Improvement starts with focusing on the verbal and nonverbal ways you communicate to employers what you have to offer. An interview doesn't end once you leave the company's door, though. How you follow up after the interview can also help determine whether you're the person offered the position. How ready are you to put your interviewing skills to the test?

This resource provides instruction for users to:

Describe how nonverbal communication skills can affect an interview
Describe how to answer interview questions effectively
Describe best practices for following-up after an interview

• Acquiring Data--Sources and Methods

Adding Structure--Parsing Data and Data Models

This title picks up with the second stage of what traditionally is referred to as an extract, transform, and load (ETL) pipeline, adding structure through the transformation of raw data. Learners will see how to work with a variety of data formats, including XML and JSON, by parsing the data we have acquired to eventually load it into an environment better-suited to exploration and analysis: a relational database. But before we load our data into a database, we take a short diversion to talk about how to conceptually model structure in data with code. Learners will get a primer in object-oriented programming and learn how to leverage it to create abstractions and data models that define how they can interface with the data.

After completing this resource, Learners will be able to:

Understand the ETL Pipeline

• Adding Structure--Parsing Data and Data Models

Storing Data--Persistence with Relational Databases

This resource starts with an introduction to one of the most ubiquitous data technologies–the relational database. The content serves as a capstone to the ETL pipeline of the previous videos where you learn the fundamentals of databases with SQLite and how to interface with them in Python.

USING EXTERNAL AND INTERNAL LINKS

The simplest way to store web content for an individual website is to place all the files in the same folder. When files are stored together like this, you can link to them by simply providing the name of the file in the href attribute of the <a> tag. When you have more than a few pages, or when you start to have an organization structure to the content in your site, you should put your files into directories (or folders) whose names reflect the content within them. For example, all your images could be in an images directory, corporate information could be in an about directory and so on. You can use relative addresses, which include only enough information to find one page from another.

Flow control statements let you control what code is executed when using conditions and loops on your site. Conditional statements, like if A, then B, else C help you to build in logic to your site where certain elements require it. Loops will run through certain code until you designate when it should stop. Both of these controls are helpful to build in more sophistication to your work.

After reviewing this resource, learners will be able to:

Explain the steps to test conditions with the if statement
Explain the steps to
Use comparison operators to compare values
Explain the steps to use alternative conditions with else
Perform repeated statements with the for loop
Explain the steps to use while and do...while loops
Create infinite loops

RESPONDING TO EVENTS AND USING WINDOWS

JavaScript programs don't have to execute in order. They can detect events and react to them. A script that you create and use to detect and respond to an event is generally referred to as an event handler. Event handlers are among the most powerful features in JavaScript. Essentially, JavaScript uses a set of objects to store information about the various parts of a web page - buttons, links, images, windows, and so on. An event can also happen in more than one place and each event is associated with an object. Adding yet another layer to your work, this level of JavaScript will really make your web pages work.

After reviewing this resource, learners will be able to:

Explain how event handlers work and how to create them
Explain how to detect mouse and keyboard actions
Explain how event handlers relate to objects
Explain how to use onclick to change the appearance of <div>
Explain how to access and use the window object hierarchy with JavaScript
Explain how to delay a script's actions by using timeouts
Explain how to display alerts, confirmations, and prompts

JAVASCRIPT BEST PRACTICES

As you start to develop more complex scripts, it's important to know and stick to some scripting best practices. This helps you to keep straight the work that you've done when you revisit it, keeps it easy to maintain and emphasizes readability. This also allows you to ensure the code can be updated easily and allow others to understand your work easily when working as a team - which is super common in this field. It also just helps you to keep things tidy and adapt your code to other projects and/or fix things quickly and easily if something comes up.

After reviewing this resource, Learners will be able to:

Explain the best practices for creating unobtrusive scripts
Explain the importance of separating content, presentation, and behavior
Explain the importance of following web standards to create cross-browser scripts
Read and display browser information
Use feature sensing to avoid errors
Explain how to support older, less compliant browser versions
Explain how to support non-JavaScript browsers

USING 3RD PARTY JAVASCRIPT LIBRARIES AND FRAMEWORKS

Third-party JavaScript libraries are those that are not directly included with JavaScript, but they serve a similar purpose: they enable you to do complicated things with only a small amount of code because that small amount of code refers to something bigger under the hood that someone else has already created. In other words, you can avoid reinventing the wheel by leveraging existing code that exists elsewhere. Using a third-party JavaScript library is usually as simple as copying one or more files to your server (or linking to an external but incredibly stable location) and including a <script> tag in your document to load the library, thus making its code available to your own scripts.

After reviewing this resource, Learners will be able to:

Explain why you might use a third-party JavaScript library or framework
Explain the differences between libraries and frameworks
Explain how and when you might use Angular, jQuery, React, and other third-party libraries
Download and use a popular third-party JavaScript library in your applications
Explain the benefits of JavaScript frameworks

ORGANIZING AND MANAGING A WEBSITE

Organizing and presenting multiple web pages into a user-friendly experience is important to ensure visitors will be able to navigate your site without confusion. Because web sites can (and should be) updated frequently, it's essential to create pages that can easily be maintained. You should also add comments and other documentation to your pages so that you - or anyone else on your staff - can understand and modify your pages efficiently and effectively.

After completing this resource, learners will be able to:

Determine whether one page is enough to handle all your content
Organize both simple and large sites
Write maintainable code
Optimize your site for search engines
