In Tucson, Xerocraft, a nonprofit makerspace, has lathe and Bridgeport knee mill [0] and is run less formally. Also, Tucson is cheap and somewhat funky. You might like it.

Edit: Sorry, someone has gutted the web site, removing most of the information. The space itself has existed for quite a few years and I have been a volunteer member of staff since 2013. The tools are real. Despite the appearance probably given by this new website, the makerspace is not vaporware.

My experience was the same. I ended up standing on a balance board at my stand-up desk. This strengthened my core and helped me to be more alert without actively distracting me.

And yes, this should be a supplement and not a substitute for outdoor activity, normal cardio and strength training, stretching, etc.

I guess you just solved my problem. This is a topic I'm just beginning to look into. Thank you.

But now I'm wondering why are panels made this way? I mean internally they're wired in series or at least substantially so. and I've read that shading a small portion of one panel will drastically reduce the output of that one panel. Is it possible to create a panel (e.g. nominally 12 volt system) with bypass diodes inside it? If so then why wouldn't they have been doing this all along?

That is always the most important question, isn't it?

I am looking at RV applications, thinking series would be ideal to reduce wiring cost, but just learned that a small patch on one panel of shade lowers current in the whole series, when wired that way. If there's some way they could be wired as a tree, with the high amperage portion of the circuit fairly short, that seems more efficient. But then I guess I have just reinvented the power grid... I'm talking about residential scale, though, or smaller.

Just last week I was thinking we need solar cells wired up in a tree structure with batteries integrated into the tree so that we don't need to combine series and parallel or have the drawbacks of either. Is anybody doing that? I presume they would need to be connected with fluids, electrolyte in channels instead of with wires. Or have I just reinvented the tree?

I've actually received a version of whole blood UV treatment about 10 years ago. For whatever reason I ended up feeling euphoric, memorably so, one of the best days of my life. It may have something to do with the fact that I was given oxygen after I started to faint after I saw the blood being withdrawn.

I collected a lot of papers about this modality and related ones. I can share them if anyone would like. I will not be able to comment on them and I am not a medical professional. Perhaps this was simply the placebo that appealed to me.

But the reason I sought out this treatment is that it is practiced by a doctor who was recommended to me by an MD PhD neurologist at Mayo Clinic. That doctor now does more with ozone gas than he does with ultraviolet blood irradiation. he considers it to be part of a class of "oxidative therapies" including very high doses of vitamin C.

Apart from the fact that compilers are really good and generally will choose the best option for you, it seems like it boils down to what processor is used. On Android aren't ARM processors the most common?

If you'd like a curated collection of many papers on horizontal gene transfer in eukaryotes, it comprises much of the evidence presented at https://www.panspermia.org/archindex.htm . Having followed this collection since 2010, I have gotten the sense that horizontal gene transfer to/from eukaryotes is not only common but an important mechanism of evolution.

Do you like https://www.panspermia.org ? I read their "what's new" often and like it a lot.

US relies on farm workers from Mexico and is not letting as many in, partly due to suspension of visa operations.
