  • The North Carolina legislature has a supermajority of far right republicans. The NC GOP is currently brazenly attempting to throw out legitimate ballots to steal a state supreme court seat, and the courts are going along with it. If they want to move for political concerns, I don’t think NC is enough of an improvement to justify the disruption involved.


  • Another way to view it is that college classes are filled with your future colleagues, and should be treated similar to a workplace. Students should generally dress similarly to how they expect to dress in their future workplaces. Whether that excludes a tank top is a matter of discretion, but clearly the proffesor did not find it to be professional. There’s no hard and fast rule, but I am surprised by the indignant tone in the comments here. Lectures are the domain of the professor and its not outlandish for them to set expectations about what they consider acceptable conduct for their lectures.




  • The stuff that is heavier than water ends up in the river delta, everything else dilutes into the ocean. Once it’s in the ocean, there’s not much humans can do about it. Promoting populations of sea grass and filter feeders like mussels can at least capture pollution in a form that settles to the seabed and improves water quality.

    There will be pockets of pollution that persist for a long time, and floodwaters could stir some of that back up, but the above poster is correct. Cleaning up a river can be as simple as stopping the sources of the pollution. A dirty river is dirty because stuff keeps getting added to it. Of course stopping sources of pollution is way easier said than done.


  • Is the sales tax in your area 7.5% by any chance?

    $16 x (100/107.5)= $14.88

    I don’t see any gloves priced at 14.88 on their website at a quick check. I wonder if the store is trying to set a price that tallies to an even dollar amount and doesn’t know the connotation. I only recently learned about those numbers being associated so I would like to believe a benign explanation. Maybe you could ask to talk to a store manager next time you see it an make sure they know to avoid that price point.








  • Helion is a completely different technology vs tokamaks which is what you’re thinking of. They pulse the plasma to create brief bursts of pressure/heating/fusion. They do already have their seventh prototype machine operational so while we can’t independently verify their claims, it’s probably not all bluster.

    I have mixed feelings about their approach. They plan to use a deuterium and helium-3 fuel blend. That has a couple major advantages. Most of the reactions will be aneutronic and the energy is released in the form of highly energetic alpha particles and protons. The lack of a high energy neutron is a huge advantage for safety and longevity of a reactor. High energy neutrons are hard to shield from and they cause most materials to get brittle and weaken. Netrons are not good for personnel to be around and they can leave some materials radiactive making reactor maintenance/disposal costly. The other advantage is that since all the energy is released as kinetic energy in charged particles, they don’t have to try to absorb high energy photons or neutrons into a water blanket to drive a steam turbine. Instead, the kinetic energy results in an electromagnetic pulse that can be harvested by the same magnets that constrict the plasma to begin with.

    Sounds amazaing, right? So why doesn’t everyone use this approach? Helium is rare, but Helium-3 is especially rare, making up only about 20 parts per million of helium found in geologic deposits. So simply put, it is currently infeasible to use Helium-3 at scale. Helium-3 can be collected as a byproduct of breeding tritium for use in nuclear warheads. Enough helium-3 is produced for some demonstration reactors, but any real amount of demand will quickly outpace what the DOE produces.

    Helion plans on breeding their own Helium-3 in Deuterium-Deuterium reactors they will operate. However D-D reactions are not aneutronic. So all the materials lifespan/shielding/ maintenance nightmares that come with operating a nuclear reactor will still apply. That means operators will have to buy very expensive fuel from Helion indefinitely. Helion doesn’t exactly deny this drawback, but I really dislike how much they gloss over it in their public communications.

    Here’s a video tour of their test facilities that explains the basics of their approach. https://youtu.be/_bDXXWQxK38

    I’m inclined to think they’ve demonstrated enough results that they are likely to be able to build a working unit quickly, however, that would still be a long way off from creating any sort of sustainable supply chain that would be a viable option for anyone beside datacenters.


  • Taking an oral steroid like prednisone can help prevent asthma attacks for milder allergies, but that might not be sufficient for a severe peanut allergy.

    Epinephren is not a gentle drug. You do not want to have to use an epi pen if you can avoid it. It causes the heart to race and result in lots of side effects that would make a flight extremely uncomfortable. I think it’s also metabolized quickly enough that a single dose is not going to last a whole flight.

    I’m not an expert though, I just have multiple family members with moderate to severe allergies.




  • I see it as an extension of the myth of American purity and external corruption. “This person is evil, some outside power must have compromising info on them.” “Immigrants are violent criminals preying on innocent americans.”

    These attitudes ignore the reality that bad people can come from anywhere. There are plenty of villians with very mundane origin stories. What matters is if everyone else has the will and ability to keep bad people in check and hold them accountable.

    The grifters in charge need no other motivation than a sense of superiority and an opportunity to make a buck.
