Tag: Study-HTDP

Overall it has been a pleasant experience working with Google Groups.
Rather than set up a server, install the wiki, file share, and listserve myself, and host it on the Internet; I can set up a group there instead. It is pretty convenient. Additionally, their interface is pleasant and search works pretty well (no surprises on that one!).
One decision that I made is that anyone can join the group, there are no restrictions. Additionally, there is no moderation on posts. I hope to encourage a certain atmosphere and culture. Thus far it has worked well.

Per Matthias, the best place to start HTDP is by quickly going through the prolog to the 2nd edition and then diving into the book. I posted on this here.

Q. Are we doing this to learn Scheme?
A. No. As a result of working through the book, we will learn Scheme, but the goal is to learn how write programs, not learn Scheme the programming language. For that you should read http://www.scheme.com/tspl3/.

HTDP is FREE. Basically the only thing you need to take advantage of it is a computer, interest, and discipline.
That is awesome!

While studying HTDP, there are a few opportunities that occur during the process:
Practice Blogging:

I am assuming two things:
1. We are all going to learn things.
2. It is going to be fun.
That alone is worth blogging about.
If you haven’t got a blog, this is an excuse to start one.
The tagging facilities that most blog engines provide today allow you to ‘tag’ your posts. I recommend you tag them with ‘Study-HTDP’, which is more specific than just ‘HTDP’ or ‘Programming’ alone.
My goal is twofold:
1. For you to capture your thoughts and ideas, and practice writing.
2. Expose said thoughts and ideas to other folks who may be interested in them.

Study Revision Control:

If you aren’t already using a revision control system, now is the perfect time to do so.
You are going to be writing a lot of code that you most definitely will want to tag and probably eventually branch.
Subversion is a easy, powerful place to start.
Everyone should have a SVN repository available to them for storing their work.

What we will do is to read and complete the problems in HTDP.
When we’ve got questions (or thoughts or ideas) about the content (any content, not necessarily limited to HTDP, anything CS/HTDP related is fair game), we should send them to the mailing list.
I will respond to, and post, questions every morning and every evening around 7:00am and 7:00pm or so, my timezone is:
Central Standard Time (CST) = GMT-6
Central Daylight Time (CDT) = GMT-5
Since we’ve got a geographically distributed group, many of us will be on virtually opposite schedules.
I’m thinking that every one or two weeks, we should have a chat on Skype just to touch base, identify issues and opportunities for improvement, and generally do what we can’t do well over email (not sure what that is yet, but lets find out).
Another question worth answering here is “How long will it take to finish the book?”.
I don’t know the answer to that. I interest of finding the answer, I’ve decided that we’ll timebox the first class to 4 months. There are 8 sections (with various intermezzos), which gives 2 weeks to every
section.
This is an aggressive schedule. While I expect some sections to be easier than others, I am banking on two things:
1. We’ve got a group of highly motivated people. Since most of us are doing this on nights and weekends, we *must* be interested. Besides, we don’t want this to go on forever. Without a goal, we’ll eventually lose momentum.
2. We can, and will, revise our estimate as we go along. The goal is to learn, not to meet a deadline.

We’ve made a couple of modifications since then:

1. There are two groups. Group 0 is sticking with the very aggressive schedule.
2. We added the intermezzos into the schedule, 1 week for each.

Group zero is averaging around 10 hours per week to maintain the current goal of one section every two weeks; the second week ending this Sunday (I’m tracking all of my study time in hopes of providing a detailed account of where I spent my time).

Initially, the folks participating are primarily either co-workers or non-co-worker friends who have wide range of experience and interests.
From my perspective, everyone is welcome.
The more interested, motivated participants the better!

I’ve been delighted by the number of folks that have showed up on the Internet either to participate or help. There are a lot of great people out there!

About three weeks ago I “made it official” and announced the Study-HTDP for any folks who may be interested. I figured that I would post both to the group itself, and mirror the interesting things here. It didn’t really work out that way.
Focusing on the work and not much else, I’ve posted exclusively to the group. Since we’re only two weeks into it, though, I’m going to make a change and post the most interesting content here. The reason is that I want to be sure to have a place to keep my notes and thoughts on things so that they don’t get totally lost in the overall group.

Originally I figured that a lot of my thoughts would show up here, but they haven’t. Instead they get posted directly to the group. That said, here are some thoughts from the week:

• The beginning student language is interesting: no variable binding and function definitions are only one expression long
• It is great to be able to talk to other folks about it; interested folks especially
• A disciplined approach to function definitions is fine with me!

Study-HTDP is a study group for folks who want to read through HTDP. My rationale is explained here. I suspect that many blog posts in the following months will be tagged with ‘Study-HTDP’.
I’m pretty excited to see how this turns out. I hope not only to learn a lot about programming, but also about learning with other folks, especially with this distributed/online model.
