  • Extruded aluminum of that type is insanely stable and easy enough to build for a reasonably handy person.

    You only need a cheap cutoff saw and a drill, or you can order pre-cut and ore-drilled pieces to order.

    There are a number of makers of extruded aluminum building systems, basically tinkertoys for adults. I have personal experience using 80/20 and the Tslots brands. They are functionally identical.

    I have used it to build stands for heavy equipment like ultra-cold freezers for labs. It is more than sufficient for any server racking.









  • Indeed. In intro biology they teach species concepts and then the minute you advance to the next level you are slammed with all the flaws and fuzziness inherent in the definitions.

    Biology is, frankly, the most difficult science for this very reason. Fuzzy categories are necessary for us to start understanding complexity, but the categories can become a hindrance too when you are really trying to push into new territory.

    Treat all classification schemes as provisionally useful, but never mistake them for reality.


  • I prefer ‘species agnosticism’ when it comes to bacteria, most of the time. It doesn’t matter very often what species something is in environmental scenarios like biogas digesters or composting. Their general function is more important than exactly what species they may be according to current schemes.

    The only folks who need to identify ’species’ in bacteria are in medical fields, and even then the real concern is whether the bacteria of interest carry specific genes, such as EPEC/EHEC in E. coli. E.coli is everywhere, but only some types carry the genes that make them dangerous.

    So my answer is ‘meh’. It’s useful to be able to categorize things, but it can also become an unproductive obsession. Use the classification scheme that works for your application domain. Leave the gnat-straining and bean-counting to the academics.
