This is the main web page for the course. This page, along with the pages pointed to by Links and the online Blackboard program are used to establish the "rules of the road" for the course.

This page contains important information on many different topics in no particular order. Other pages pointed to by Links contain information that is more specific as indicated by the title of the page.

Read the syllabus
You should read the syllabus for this course before reading further in this page.

Use of the Blackboard online system
The online program named Blackboard will be used for communicating with students, such as reporting grades, posting announcements, sending Email messages to individual students, and broadcasting Email messages to all students enrolled in the course.

The Blackboard Assignment and Test features are the mechanisms that you will use to submit your assignments and to take your tests.

The Blackboard "Send Email" feature is the mechanism that you will use to send Email messages to me.

Spam blocking software
I receive several hundred email messages every day. Many of the messages that I receive contain viruses or worms. Most of the rest are SPAM.

Therefore, whenever you send a new email message to me, you MUST use the Blackboard "Send Email" feature to construct and send the message, and your Subject line MUST contain a brief description of the topic. (Don't simply reply to an earlier email message from me if the topic is different.)

When I see that format, I will trust that the message is safe to open and read. Otherwise, I will assume that your message contains a virus or constitutes SPAM, and I will simply delete your message without reading it.

Questions via Email:
From time to time you may need to ask questions via email, and I encourage you to do so. However, please make the question as specific as possible. For example, "What is a DTD?" is not a question that I can easily answer via email.

If you, like many others, procrastinate and save your questions until the day before an assignment or test deadline, don't be surprised if you don't get a response from me until after the deadline has passed.

I am usually happy to answer questions about XML and JSON concepts at the level of this course. However, please don't ask questions about the assignments (unless you believe there is a problem with one of the assignment files that I have provided). It is almost certain that I won't answer them. Your performance on the assignments constitutes a major portion of your final grade, and it isn't fair for me to answer questions about the assignments from one student when all students don't have an opportunity to hear the question and the answer.

When appropriate, please illustrate your question with a short example, and refer to the corresponding section of the textbook or the module at Introduction to XML.

I am here to help you, so don't hesitate to ask for help when you need it.

Response to email:
I normally respond to student email messages within 24 hours except on the weekends. If you send a message to me and you don't receive a response within 24 hours (allow 72 hours on weekends), make certain that your Subject line is correctly formatted and send the message again.

How many chapters...?
I frequently receive questions (both via Email and in the classroom) similar to the following, “How many textbook chapters do I need to read to be able to solve problem X on assignment Y?”

My answer is usually something like the following, “Read (and understand) as many chapters as necessary to learn enough about XML and/or JSON to be able to write the code or answer the questions.

If I gave assignments in the classroom under closed-book conditions, I would feel obligated to tell you in advance how many chapters you need to understand in order to prepare for the assignment. However, my assignments are all take-home assignments. You have access to all of the assignments from very early in the semester. You have access, not only to my tutorials and the textbook, but also to any book that you wish to consult, and to numerous resources on the web, in preparing yourself to successfully complete the assignment. I consider it to be your responsibility to make use of those resources in whatever manner, and on whatever schedule works best for you.

I simply provide tutorial materials, conduct classroom lectures and discussions, answer appropriate Email questions, and establish the necessary deadlines. (Unfortunately, deadlines are a fact of life, not only in college, but also in the workplace.) I make no attempt to tell you how to schedule your time and your efforts.

So, before you ask, the answer is, “Consult whatever resources you need to consult, on whatever schedule you need to consult them, to learn enough about XML to be able to successfully complete the assignments by the required deadlines (but please don’t get human assistance in the actual writing of the assignments).”

Help me debug my assignment
Please don't waste our time by asking me to help you debug your assignments. The best way to debug is to avoid errors in the first place. Then there won't be any bugs that require attention.

If you understand the requisite XML and/or JSON concepts, the only bugs that you will incur will be the result of careless errors on your part. I won't waste my time showing you how to correct for your own carelessness.

Carelessness is costly
A few semesters back, on the last Friday of the month, which was anticipated to be one of the most active trading days of the month, programmers working on a network made a careless error and shut the NASDAQ stock exchange down for several hours. There is no way of estimating how much this cost various people around the world.

A few months later, programmers working for a telephone company made a careless programming error and swamped the 911 emergency call center in Austin with wrong numbers for several hours. Hopefully no one died as a result, but we will never know.

Although careless errors on assignments may not be as costly as the errors described above, they are costly nonetheless. In fact, the cost for making a careless error on an assignment is just as costly as not knowing how to write the assignment in the first place. In either case, you get no credit for the assignment. So, don't be careless.

Who Am I?
I receive many email messages addressed to Dr. Baldwin, and I appreciate the courtesy. My highest degree earned is a Masters Degree in Electrical Engineering, and I am a full Professor at ACC. Under the circumstances, Prof. Baldwin is a more appropriate salutation than Dr. Baldwin.

Please Be Patient
Other than questions regarding registration, please do not send email regarding this course prior to the first day of classes. If you do, I probably won't answer it. A great deal of preparation is required to teach a course of this nature. I have many responsibilities to take care of in the final days before the course begins and I do not have the time to work with individual students until after the course actually begins. If I reach the point that I can accept email regarding this course prior to the first day of classes, I will post that fact as an announcement in Blackboard.

Instructions and specifications
The biggest challenge that many of you will face in successfully completing this course will be learning how to read, understand, and comply with instructions and specifications (see Online Orientation).

Computer Studies Student Information Form
The following information is requested by the Computer Studies department, but is not a requirement of the course in which you are enrolled. Whether or not you provide the following information will not be taken into account when determining your grade in the course.

If you are willing to provide this information, please use the Blackboard "Send Email" feature to compose a message containing the following information and send it me.

If you do provide the information, please make the subject line of your e-mail message read as follows: Student Information Form

You should be able to copy and paste the following form into your Blackboard Email client and then fill in the blanks. Don't be too concerned about neatness when filling in the form.

Do not send executable attachments
If you send an email message to me and expect me to read it, DO NOT attach any executable files, even if they are encapsulated in a zip file. This includes files with the following extensions, just to name a few:


If you do send such files, my virus blocker will simply reject the message and I will never see it.

The following file extensions should be OK:

.zip (Provided the zip file doesn't contain any executable files.)

If you find it necessary to send a questionable file for any reason, you should also send another message without an attachment notifying me that you sent the questionable file as an attachment so that I can be on the lookout for it.

Your official Email address
It is my understanding that all ACC students have been provided an official Email address by ACC, and that address is reflected in all official ACC student records. I have been told that you can cause messages sent to that address to be forwarded to the Email address of your choice. You should make it a point to either forward those messages, or to check your ACC Email address on a daily basis.

When I need to send a broadcast message to all students in the course, (and in most other cases as well) I will send that message to your official ACC Email address. If you don't check you mail at that address, you won't get the message.

Also, if I need to send feedback to you regarding problems with an assignment or test, I will normally send that message to your official ACC Email address.

Publishing at
I am in the process of publishing much of my online tutorial material in an EBook at Introduction to XML. There are no advertisements on that site.

In addition to normal online viewing, you can download all of the modules in a single pdf file in a book format for offline viewing. You can download the modules in html format in a single consolidated zip file. You can also download the modules in different formats that are compatible with mobile devices.

You can also purchase the entire EBook in printed form from this site. (Note that I receive no compensation when you purchase the printed version of the EBook.)

Programming Oldies But Goodies
You will also find many of my tutorials published free of advertisements at Programming Oldies But Goodies.
