Dear 43 Things Users,

10 years after introducing 43 Things to the world, we have decided we have met our last goal: completing the incredible experience that has been 43 Things. Please join us in giving one last cheer to all the folks who have shared their goals with the world, as well as all the people who have worked at The Robot Co-op to build this incredible website. We won a Webby Award, published a book, and brought happiness to a lot of people.

Starting today, 43 Things users can export their goals and entries from the site. Starting August 15, we will make the site “read only”. 43 Things users will still be able to view the site and export their content, but we won’t be taking any new content from users. We hope to leave the site up for folks to see and download their content until the end of the year. Ending on New Year’s Eve takes us full circle.

It has been a long ride (one of our original goals was to "build a company that lasts at least 2 years” - we beat that one!) While we wish the site could live on, it has suffered from a number of challenges - changes in how people use the site, the advertising industry, and how search engines view the site. We wish the outcome was different – but we’ve always been realistic about when our goals are met and when they aren't.

As of today, you will be able to download your goals and entries. See more about that on the FAQ page. Thanks for 10 great years of goal-setting and achieving.

generate all the order-9 graphs

apteryxSecond attempt failed

The new, faster program used up so much memory that it got really slow due to swapping virtual memory on disk. It ran for 11 days and generated a little over 213,000 graphs, and then my boss rebooted the computer again.

Next time, I’ll have to just put the graphs into a database instead of holding everything in memory. And use a different computer.

I’m giving this low priority for now, though. 8 years ago

apteryxFirst attempt failed

A few weeks ago, I wrote a Python program to generate all the order-9 graphs. I ran it on my boss’s dual-CPU G5. It ran for a week, until my boss rebooted the computer. It had generated about 180,000 graphs. I think that’s almost all of them.

I modified the program to use more “hashing and caching”, a better way of spotting non-isomorphs, and to auto-include complements of graphs with fewer than 36 lines. That sped up generation of all 12,346 order-8 graphs from 125 minutes to 9 minutes. I started it running on the order-9 graphs yesterday. It generated the first 50,000 or so very quickly, but now the memory usage is at 1.5 GB, so I think the process is doing a lot of swapping. It’s completed 114,000 graphs now, and is generating about 1000 graphs per hour. 8 years ago
