  • I meditate as part of a dedicated yoga practice. When I am doing a group practice, i arrive early and perform a physical warm up and then spend ten minutes in a seated meditation before the class begins. It makes a huge difference in the quality of my workout to get my mind firmly rooted in the immediate experience.


  • Back when Perl was the language of choice for bioinformatics, I found a huge performance boost pre-processing large (~1Tb) text files using built in unix tools like sed and awk with regex. So while it might take me a full hour to peck out the correct incantation, the task would then run in an hour, compared to four hours or more for the same task using Perl.

    So many pipes…






  • I’m going to try to revive a dead post by commenting on my own experiences playing. Based on the upvotes, others seem interested too. Let’s see if it works

    I had a good crew of friends while in grad school in the 00’s. This was a super smart crew of bio-nerds so when I heard about this game on Slashdot (or maybe Memepool, can’t be sure) I knew I had the right crowd to try it.

    It was a successful session and we developed a lot of those inside jokes that tight social groups do.

    I tried again years later with another set of friends and it fell flat. Not a disaster but it was quickly abandoned for lack of general interest. This was also a crowd of high-wattage personalities so i still wonder what the difference was.

    That’s what prompted my question. Just seeking scene setting tips that might increase the chance the game goes well again.





  • Yes, I’d think that would be the goal. Long term habitation will need plants of many kinds. Just start listing all the ways people benefit from plants and you’ll see the list just goes on and on. At the huge price per kilogram of launched mass, making soil out of local materials and developing closed-loop systems just makes economic sense. Soil is a living thing after all, it doesn’t wear out or go away. (Older than dirt!) Learning how to make healthy functioning soil from native regolith is an important part of the whole in-situ resource utilization push from the major space agencies.



  • Hydroponics requires biologically available nitrogen too and it has to come from somewhere. The point of these experiments is to explore a wide variety of scenarios. Hydroponics as a growing method has some drawbacks too. Any robust food production scheme in space will likely include a mix of hydro- and geo-ponics (fancy name for soil growing).

    Also consider the non-food benefits of living plants and soil. Any long term habitat on the moon or Mars will need living plants for the psychological and air quality benefits. There is a massive body of research that shows the benefits of having trees around. There is even research that shows just smelling healthy soil can be antidepressant.

    Let’s say we enclose a large lava tube, one seriously considered approach for long term habitats. Having some greenery would go a long way to staving off Space Madness.
