Does TSA give you a hard time when they see that rig pop up on the X-ray?
GoldenRacer · a year ago
I have a similar setup. Corne keyboard, trackball mouse, portable laptop stand. Never had an issue with TSA. I don't even bother taking the keyboard out of my bag since each half is roughly the size of a cell phone

It absolutely does, and with the recent uptick in recreational nitrous use we have clear examples of what it does to people. This is just one of the handful of cases of nitrous overuse leading to long term mobility loss

I'm not sure I understand what you're saying. That article appears to be about a women who is now in a wheel chair due to nerve damage caused by a b12 deficiency which supports my comment that one of the most concerning risks of nitrous use is b12 deficiency.

The author says nitrous use doesn’t occupy any cultural space but for me I associate it with Aleister Crowley and the many “magick” things that he influenced- it was used before a lot of rituals they did. William James was a big early influence for him. But also he did a lot of other drugs too.

Looking the mechanism of action - that it replaces oxygen in the brain - it’s pretty obvious why long term use can be so damaging to your brain. It might also contribute to how crazy Crowley gets in his later years.

I don't think replacing oxygen in the brain is the main mechanism of action (in medical settings they mix nitrous and oxygen and it's still effective without risking hypoxia). Looking at Wikipedia it says the mechanism of action isn't fully understood but it says the effects "are likely caused mainly via inhibition of NMDA receptor-mediated currents".

I've been under the impression that biggest risk of long term use of nitrous is that it causes b12 deficiency which is really bad for your nervous system. Wikipedia also mentions that NMDA receptor antagonist in general are neurotoxic and studies in mice suggest that nitrous has this neurotoxicity.

32 meters is 35 yards, to within about an eighth of an inch. How's that grab you ?

My favorite is 1 mile = phi kilometers with <1% error

If I understood this correctly, would this allow you to make an extremely good estimation of direction of velocity? If you want to use dead reckoning to estimate position, how would you know the abs of the velocity?
GoldenRacer · 2 years ago
I'm way out of my depth here but I believe this would function as a very sensitive accelerometer. The rubidium would be still relative to the lasers so when you accelerated, it would have inertia and take some time to catch up with the rest of the device. You'd then integrate the acceleration to find the velocity and integrate that to find position.

I tried Kagi and even signed up for the basic plan but ultimately cancelled. If the basic plan included twice as many searches per month, I'd be all in. However, I find Startpage results are "just as good" and free. I didn't use a lot of the other Kagi tools.

So make it cost less or offer more and I'm in Kagi!

GoldenRacer · 2 years ago
I've been using kagi and that's my biggest complaint. Upgrading from the basic plan seems like a lot of money but being on the basic plan, I have mental friction every time I do a search because I have anxiety about running out of searches. I actually haven't ran out in the 3 months I've been using it for but I don't like the anxiety 300 searches/month creates for me and maybe I would run out if I didn't have the anxiety limiting me
GoldenRacer commented on Deadly morel mushroom outbreak highlights big gaps in fungi knowledge   arstechnica.com/science/2... · Posted by u/kristianp
micro_cam · 2 years ago
I've eaten at Dave's and also gather and eat morel's regularly in Montana.

Dave's is a popular joint but didn't strike me as particularly good even by Sushi restaurants in Montana standards. They had some creative rolls but seemed to fail to get the basic fish cuts and rice seasoning right.

What they were doing marinating the morel's and eating them basically raw is ridiculous. No one who is experienced with morel's does it that way and most mushroom guides contain info on hydrazine contents/risk and suggested cooking methods.

March and April is too early for Montana (or most US) Morel's which are commercially picked in forest fires from the previous year once the soil temperature reaches 54 degrees. I heard at one point these were grown in China and wouldn't be shocked if they are a different [sub]species that might contain more hyrazine. There are also some "false morels" that fruit earlier (one species is known as the snow morel as it comes up right after snow melt) but these are easy to identify contain even more hydrazine.

GoldenRacer · 2 years ago
The article also claims they were imported from China. They also said samples were sent for genetic testing and confirmed they were of the species Morchella sextelata. Not sure if that is what you're referring to as a species with a higher hydrazine content but I agree with you that you should be cooking them regardless and it's strange to me that they were serving them raw.

Math, sure - doesn't the understanding of physics also go through changes? Do we really understand the reality of the world; or how do we know our current understanding of it won't change?
GoldenRacer · 2 years ago
Asimov wrote an essay called "relativity of wrong" that I think does a good job of capturing the changes our understanding of the world goes through.

Yes, Einstein's theory of relativity was a change from Newtonian physics but it's a fairly minor correction for most practical purposes and Newtonian physics is still important to know and understand.

So yeah, our understanding of physics will likely change but it'll only matter in more and more extreme edge cases and will likely build on our current understanding. Maybe it'll result in us finally having fusion reactor, room temperature super conductors, or quantum computers but you're still going to get a roughly parabolic arc when you throw a ball through the air.

GoldenRacer commented on Across the country, houses of worship are going solar   grist.org/buildings/more-... · Posted by u/geox
solardev · 2 years ago
I don't see how this is significant...? So 1.9% of 0.6% of non-residential buildings have PV. Okay, so what? Warehouses, gas stations, parking lots, apartments, campuses... solar is everywhere. Why is it notable that a tiny minority of HoW also have PV? Even if they accounted for, say 3% of all non-residential PV... still, so what?

(Not directed at you, parent poster, just wondering out loud. Like I don't get why this was a study at all, much less what the results signify...)

GoldenRacer · 2 years ago
Doesn't having those numbers available help you ask questions like "why are houses of worship more likely to install solar panels than a warehouse?" which could possibly point towards answers to the question "how can we increase the percent of warehouses that are installing solar panels?" Maybe it doesn't lead to anything (many churches are more motivated by ideals and less motivated by profit than a warehouse) but studying outlier categories even if they're minorities seems like a reasonable thing to do.

Ok, maybe synthetic is a better word for many instances of their use. As in synthesized with the aid human intervention.
GoldenRacer · 2 years ago
Where exactly is the line drawn for how much and what type of human intervention is required? When I cook food, human intervention is causing chemical reactions that change the composition of the food. I doubt many people consider grill marks to be unnatural or synthetic.
