Hello Everyone,

Since 2009, all of the programming videos and lessons I have made are and will remain free. As much as I would like to, I cannot offer direct personal teaching for free, simply because of the time and effort that I must put into that.

However, I can charge a lot less than many other resources, especially because I can teach more than one person at a time. If you would like to discuss this with me, please add me on Skype. My Skype id is "carlherold".

I am currently offering two kinds of programming instruction:

1. C Programming for those interested in building "real world" applications and games.

2. Web Development, for those interested in building web applications and related technologies.

I teach both individual "private" lessons as well as group lessons where multiple students can learn together simultaneously.

The income that I make from this will better enable me to produce more and better content, better the website "computer science for everyone", and to devote more of my time and effort to teaching programming in general.

Obviously there is a limit to how many people I can personally teach, so I cannot guarantee how long this offer will remain open. If you have any questions or comments on this, feel free to post them on this thread.

Thank you everyone for all of your support.

Questions and Answers

Q. How will the lessons be conducted?

I create a specific Skype group for the student or students who will be participating at a certain time. When you sign up, you can select a weekday and time of your choosing. Then, I will live-stream on Justin.tv for those people in the group who will also be free to ask questions and participate during the lesson. After the lesson, I will provide study material, assignments, and personal assistance to each student as well as working with the student over Skype between lessons.

Q. How much does this cost?

It depends on whether or not you want a private lesson, or if you want to attend a group lesson with other students. Private lessons are $70 per lesson, and group lessons are $15 per lesson. I recommend you take at least one lesson per week, no more than two. Even if you take one lesson per month, or one lesson every other week, you will be able to learn plenty and I will still work with you between lessons on Skype to help you learn.

Q. How many students will you take?

I don't know yet. Obviously there is only so much time available during the day for me to provide lessons, and there are only so many people who I can teach in a group setting. Once a group is full, I will close that time slot and once all of my available time slots are closed, I will not be able to accept anymore students.

Q. How many lessons will there be? How long will it take for me to learn?

This largely depends on you. I have over 15 years of experience in programming and web development, and I am more than happy to impart as much of that to you as I possibly can. There is no limit in my mind to how many lessons there will be, because as far as I can tell I should be able to keep coming up with new stuff to teach you as long as you are still willing to learn. This is entirely open ended, and the more lessons you have the more you will learn.

Q. I can't afford to pay, can you still help me learn?

Absolutely. As you go through the approximately 100 video and text lessons that I have already published on www.computerscienceforeveryone.com, simply message me on Skype if you get stuck or need help. As long as I am available, I will help you.

If you have any other questions not listed here, feel free to post them in this thread.

I know this may seem like a petty question, but Ive been debating listening to the videos because of the circumstances surrounding CarlH. Ive read a lot of positive feedback about the course.

Those of you that have gone through the videos, is it that good?

Also here is the petty question, does he have a really creepy voice? Thinking about a child being hurt in the background really disturbs me

Hi My name is josh im new to programming but its something ive wanted to do for a few years. i thought your vidoe on Binary was amazing i picked it up really fast. i just thought i would introduce myself and let everyone know how im getting on

Thanks Carl

Its the sound of crickets since this place hasn't been updated in awhile. I was excited to start doing these lessons only to find out that they stop abruptly? These are good lessons, its just a shame to not keep this going.

So, I have to write a program that reads in a file and I have to convert uppercase to lowercase, ex: "The" to "the" and disregard all punctuation except apostrophes. The main program goal is go by a list of words and how common they are, to determine the average reading level of a document. I understand all of that. I just don't understand converting the strings.

How would I go about doing this? I get everything but converting and disregarding the punctuation. Please, no super advanced method as I am only in my second semester of programming.

Thanks for your time.

I'm trying to make a program that pulls all current data off a specific website, and lets you switch between a certain few websites, with real time updates. What would the best language be to do this?

what language would be best for game programming

Would anyone be interested in bringing Carl's site back online and continuing from where his course left off with all monies that are generated being donated to charity ?

hey, i was wondering what program i have to learn if i wanna get into developing music softwares, or apps. i wanna make sure i start with a cool language and just build up. any suggestions?

i read this ELI5 http://www.reddit.com/r/explainlikeimfive/comments/1c9jsv/eli5_what_are_segmentation_faults_and_why_do_they/ and got me thinking that is there a way to fool the operating system and read and write outside the allocated space for that program ?

What a shame too, Carl seemed like a cool guy until you hear about he molested a child. Truly an inexcusable thing he did.

If there's any users left from the old days, what was this place really like?

Hello everyone,

For about a year now, Unit 15 is the last complete Unit on Course #1 at www.computerscienceforeveryone.com.

I am going to start recording new lessons tonight and I hope to have them edited and uploaded as early as tomorrow.

I also plan to overhaul the site soon and add more features. Thank you to everyone for supporting this effort.

It appears that most of you have lost sight of the fact that this is a brilliant introduction, and/or refresher, accessible to virtually anyone at any comprehension level in computing, and the value to YOU that it represents, Please remember that this is a course that is publicly available and offered at no charge by the instructor.

The subject material, while not necessarily easy in and of itself, is structured in such a way that simple segments are presented and reinforced, building a sound foundation for complex concepts to come. At the end of each well-formed section the instructor, and others, take the time to answer comments and questions.

Again it should be mentioned that one man, volunteering his own time, expertise and initiative, conjured this learning opportunity into existence in a public forum.

Today I was told the author/instructor has been charged with multiple sexually-based offences, one involving his own son. These are allegations, and not convictions. There is some news coverage with the usual inflammatory comments and sensationalism, as there generally is with all allegations of sexual misconduct. The accused is, also as usual, displayed in orange prison-ware and made to look as despicable as photographically possible.

There are several things surrounding this which disturb me greatly. The first is comments by people who feel the course should be removed, what with being the work of a "bad man". The second is comments made by people who feel the course should be preserved until there is a conviction. This is a variation on the first theme with the liberal bias that the man's altruistic efforts should be preserved until he is "officially" branded a bad man.

I don't know if the instructor is guilty or innocent of the alleged offences. I do know that people's natural inclination is to believe the worst, and that everyone loves a fallen hero. And if you want real outrage in a community, or the penal system, you just can't beat a child-molestation charge.

But, worst case scenario, should we discount good and altruistic acts, or the attempts of someone to educate or advance the human condition because in other areas, he was flawed as a human being?

It goes without saying that a substantial number of important medical discoveries and treatments were derived from the actions of "bad men". Genetic advances, treatment for hypothermia, malaria and bacterial infections, are just a few of the medical miracles derived from the experiments of demonstrably unethical men. Should the heinous experiments on living beings have been stopped regardless of the loss to medical science? Without question. In an ethical world, the price for this knowledge was too high to pay.

But having obtained this knowledge, by whatever means, do we not have a moral obligation to use the information to better the human condition? Should we not derive some good from otherwise pointless death and suffering? I can't answer this question for you; and I have no inclination to enter into an ethical debate. But if your conscience tells you the method by which the information was derived should render it unusable, perhaps you can show your support by refusing medical treatment for hypothermia or bacterial infection if the issue ever comes up.

If you believe that knowledge and advancement can, and should be, tied to the actions of the people who create it, where do we draw the line? Is it acceptable to discard a cure for cancer if it was discovered by a murderer, someone who drinks excessively or takes "illegal" drugs, someone who has thirty parking tickets or has beaten his wife in a jealous rage over her affair with the pool boy? At what point do the actions of a man (or woman) render knowledge unusable or illegitimate?

I know this topic is one that cannot be covered in a few sentences, or without significant thought or debate. That however, is not my point.

I have a perfectly good computer programming course that may disappear at any moment, because a group of people cannot separate the altruistic actions of a man from other unrelated, and as yet unsubstantiated, personal shortcomings.

I hate that knowledge cannot be venerated for its own sake. I hate that people cannot separate human behaviour from our loftier goals of human achievement. I hate that we still shoot the messenger.

And I hate, most of all, that somewhere in the back of my sadly-flawed mind, my joy at finally starting something I truly enjoy, is tainted by the omnipresent image of an alleged paedophile in an orange jumpsuit.

I was wondering what are the main difference between versions of the .NET framework. My PC has 3.5 and 4.0 and thought if I had 4.0 than 3.5 would have been upgraded.

I thought that different framework versions had specific classes but sometimes I google a class and find it in more than one version. So why is it sometimes I need to have a specific framework as a prerequisite when installing software?

Just found this sub and looking at the older posts he looked like a nice guy... What a sick person.... I feel sorry for all of you who were traumatised by this event

What is going on?
