I'm Simon Haynes.
Welcome to
Spacejock Software

On this site you'll find my free software including favourites like yWriter, yBook, FCharts and more.

Are you looking for a freelance programmer? I occasionally take on additional projects, conversions, etc.

I'm also an author, with five sf comedy novels in print (details, Kindle) and a junior science fiction series for ages 8+ (details, Kindle).

I think they call that multitasking. I call it a lot of work.

Why Free?

New Release!

Yard Fail

Free book catalogue software
by Spacejock Software
Runs on all versions of Windows, 32- or 64- bit and Wine on Linux & Mac

Primary download site: BookDB2 Full Install (1.8mb)

A note about the next version
I started work on BookDB3 a couple of years ago, but haven't had time to finish it off. I've uploaded an early test version which will import your BookDB2 data and allow you to test the new user interface and features, but development has pretty much stalled. (I only have so much time to work on my software.)
However, if enough people register BookDB I'll resume work and finish the updated version off. Therefore, if you're a regular user of BookDB2 I encourage you to register if possible.

1) Download the installation file. Internet Explorer users are forced into a series of pointless* security warnings which look something like this:

Cannot be verified

Just click Save. You'll get another warning (this one with a nice friendly red X):

Cannot be verified

Click View Downloads:

Cannot be verified

Once the downloads folder is open, locate the downloaded file and run your normal anti-virus scan on it. Once you're happy it's free of viruses, run the installation file. On Windows 7 or later, you must right-click the installer and choose 'Run as Administrator'. Now Windows will probably throw up another warning similar to the one below:

At this point you either trust me (and my company, Spacejock Software) and click 'Yes', or you click 'No' and delete the installer. That's up to you - just bear in mind I set up this website over ten years ago, and if I was offering dodgy software someone would have closed it down by now, wouldn't they?

2) Follow the prompts to set it up. (The defaults are fine)
3) Locate the Spacejock Software entry in your start menu. The program you just installed will have an entry there. Click the program icon to run it.

System Requirements:
Visual Basic 6 runtimes (included in the installer)
Any version of Windows, right back to Win 95. (e.g. Win95, Win98, Win2K, XP, Vista, etc)

Hardware: if you're running Windows, you can run my programs.

Vista users should read these additional comments.

Linux users: This app installs and run under Wine, at least on Ubuntu 7.10

You can run my programs from a memory stick. See How to run your applications from a thumb drive for more info
