Sorry if this is a little bit off topic, but I'm pretty jazzed about some new projects I'm beginning.

It all started out with me thinking through how to get my 15y/o son away from World of Warcraft long enough to have some other kinds of fun and maybe learn something. He's got a great mind and does well in science and math in school, and says he might be interested in engineering (or medicine) as a career. So I started looking around for some projects we might do together that would be fun for both of us and that I could use as a vehicle for teaching him some technology.

Most serious computer users have probably at least heard of Alan Turing, but unless you're very serious or have a formal computer science education, you probably don't really know much about him and his work.

I was browsing about last night and came across this really good video about Turing, which does a great job describing his contributions to computer science. The video is interesting and does not require a degree in math to understand. Hope you enjoy it!

As a collector and user of old computers, I'm also constantly looking for old books and documentation. I guess I'm a bit weird, but I collect the stuff. I like to read it, and I like using the old software that much of it describes.

Books are relatively easy: I go to Amazon, search, and buy used. It's amazing what you can get for $.01 plus $3.99 shipping. And it's amazing how many old computer books from the '60s, '70s, and '80s are out there. I buy Unix and CP/M related books, and books about old programming languages like Fortran, Lisp, Pascal, and Snobol.

More recently, I've been getting back into running CP/M, both on real hardware (a Kaypro 4) and emulation (SIMH Altairz80). I also sometimes play around on a TRS-80 emulator running TRSDOS or LDOS. These are fun old systems and there's a ton of old software for them in various archives around the net. I have large archives of stuff for both systems.

If there's a problem, it's mostly with documentation, especially for the more complex packages like programming languages, text editors, word processors and the like. Often the documentation is out there, but it's in pdf format, when I really wanted it as a real book. Forgive me, but for me a real book that I can touch and even smell, is oh-so-much better than a pdf file.

Enter Lulu! Lulu is the creation of Bob Young, who you might remember as the founder of Red Hat. Lulu is a self-publishing service. Authors can upload content, have it printed and bound in small or large quantities, and shipped to purchasers. It's a turnkey service. You can create your book and sell it directly from the Lulu.com service.

Here's what Lulu says about itself on the About page:

 

Lulu is changing the world of publishing by empowering authors to publish their work themselves for free with complete editorial and copyright control. Lulu.com has truly become home to a new economy. Millions of registered users and two million site visitors each month as well as offices in Raleigh, London, Toronto and Bangalore, enable Lulu customers to reach the globe.

Lulu eliminates traditional barriers to publishing and enables authors to sell their work directly to their particular audience – no jumping through hoops to find a publisher who is likely to reject their work. Using Lulu’s simple publishing tools, they format and upload their digital content. Then they can take advantage of Lulu’s global marketplace, social networking and author services, free customized online stores and retail listings on Amazon, Barnes & Noble and much more. Lulu’s lucrative 80/20-revenue split empowers authors to profit from their work.

My company uses Lulu to publish the users manuals for its software. My personal use is more mundane. I upload old manuals that I find archived on the net. They were generally scanned from the originals and saved as pdf. Then I print and bind them for my own use. A 300 page manual might cost me $15 shipped to my door. I don't have to use any laser toner or a ream of paper. I don't need to buy a binding machine or three ring binders. The books are professionally done with covers of my own design.

My latest Lulu creation is a Microsoft Fortran-80 manual. This one is from 1977, and the scan was pretty good. I uploaded the 11MB file to Lulu, created the book in a couple of minutes, ordered and payed with Paypal, and had the book in hand in less than a week. Now, when I want to sit down and do some Fortran programming, I can have the manual in front of me just like in the old days.

It's all good!

If you're not familiar with Lulu, I'd encourage you to go take a look at lulu.com. They provide a great service to authors, and to collectors of old stuff!

I wrote a blog entry over on Connect757 this morning about the lack of onine privacy on the social networking sites, facebook in particular, and google.

In my view, these businesses essentially exist to disttribute informattion about you. It's their most valuable asset. The idea that they will make it easy for you to keep your information private is wishful thinking. They willl always be tempted to sell information about you: your friends, your purchasing habits, your browsing habits, your like and dislikes, and anything else they can find that might make them a buck or three. Their ownership will demand it.

So imagine my surprise whenn I got home tonight and saw an article mentioning that facebook has once again revamped their privacy policy and now proviide a single click method of keeping all your information private.

What am I missing? I will not be rejoining facebook after deleting my account a couple of weeks ago.

I haven't written an entry here for a while, and it seems some things have changed...

My feelings about ancient Unix have perhaps evolved a bit, as has my collection of retro machines.

There are so many nice systems out there. My job is to resist purchasing them.

I'm really conflicted here... I really want to add some new systems to my very small collection, but I have a limited amount of space, money, and time to give it all the attention it deserves.

After telling myself over and over that I have too much computing equipment, I did the unthinkable, though probably inevitable: I bought an old computer.

It was on eBay for a pretty good price, and is apparently in good working condition - a Kaypro 4 from the very early 1980s. This is a 64KB Z80 powered machine with a pair of single sided 5 1/4" floppies running CP/M 2.2. It comes with all the original software on floppy, and I hope with the original manual set.

This is one of those machines that I could not afford when it was new and I was poor, but that I dreamed of owning someday. Before I could afford machines of this class, they were already gone, and I ended up with a Zenith Z-248 that I bought at DoD contract pricing.

My plan is to do whatever is necessary to get it back in perfect condition and then just play with it. Maybe I'll install a BBS, maybe I'll do some assembler or pascal development.

I'll post pictures and restoration progress after it arrives, hopefully in great condition.

The software that runs this site is an Open Source (Affero GPL 3) web application from Concursive, called ConcourseConnect, a feature complete, enterprise ready directory, social networking, and community management application. It's kind of social networking meets business, and contains features unheard of in any other Open Source, or even commercial software today.
