  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.

  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.

• ⁨Comment⁩ on ⁨Helion eyes Washington site for 2028 fusion reactor build⁩ ⁨⁨1⁩ ⁨month⁩ ago⁩:

  Helion is a completely different technology vs tokomaks 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. 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.

  This article fails to provide numbers that would distinguish between declining demand, vs these players failing to compete with consoles. When I was shopping for uhd capable bluray players, the cheapest ones were around $400 and the ps5 was $500. With how much more capability a gaming console has, you would have to be completely indifferent to gaming to buy a player over a console.

  www.eia.gov/todayinenergy/detail.php?id=61545

  The middle east is definitely a major producer of oil, but the US produces even more.

  However, what would likely impact the world even more is that the US has the largest refinery capacity and exports 15% of the petroleum products it makes. Global refinery capacity is 103.5 million barrels per day, the US constitutes 18.4 million of that. While it’s relatively quick for other oil producing nations to bump up their crude production, any major disruption in refining would have huge effects on the prices of petroleum products. Refineries are very expensive and complex. They cannot be scaled up quickly unless there is idle capacity to bring back online.

  Those are good addendums, but I’ll add one more qualifier to your nasal rinse suggestion. Never use tap water. Use only distilled water or water that has been boiled. Pharmacies also sell aerosol cans with saline solution, which is what I use for the convenience factor. Then you don’t have to worry as much about sanitized water and mixing up a solution. Saline rinses should also have at least half an hour of being upright before laying down. Don’t do a rinse then immediately lay in bed.

  If budget isn’t tight, all bedding including the allergy covers benefits from getting in duplicate so you can take your time with the laundry. I was a lot worse about washing bedding when remembering late in the day meant there wouldn’t be enough time to wash and dry before bedtime.

• ⁨Comment⁩ on ⁨Am I allergic to my dog, and if so, what solutions do I have?⁩ ⁨⁨5⁩ ⁨months⁩ ago⁩:

  Sounds like you have already convinced yourself the answer is probably yes.

  You could also have a high sensitivity to dust mites. Talking to an allergist could help you narrow down what specifically bothers you. Allergy tests aren’t that big of a deal to have done.

  Before trying to rehome the dog, do your best to make your bedroom a dog free zone. Keep the door closed and don’t let her on your bed. Shower before bed and don’t touch your dog between showering and getting in bed. Wash your bedding often. Don’t ever sitnon or get in your bed in clothes that have been around your dog or on furniture your dog is allowed to lay on. An air filter can help, but is limited in what they can actually accomplish. Filters can help with dust that comes in through your hvac vents, but any sources of allergens in your room will easily produce irritants at a much greater rate than a filter can capture them.

  I’ll avoid specific medical recommendations, but I will list a few things worth checking out. Non-steroidal nasal sprays could help your sleep. Nasacort was the one recommended to me by a doctor. One lesson I had to learn with that is to not use it right before laying down. You need to give it time to drain. It does bother my stomach a bit, so timing it with a meal or snack can help. Pataday and opcon-a drops have both been helpful for me. Opcon-a does cause a temporary burning sensation. I would recommend starting with lower dose twice a day variants The extra strength stuff also hurts my stomach. (your eyes and sinuses drain down your throat.) Eye drops and nasal sprays are more targeted than tablet antihistamines so they can be a little more effective.

  You might want to ask your doctor about a sleep study. In my unprofessional opinion, I would suspect you are experiencing apnea.

  If you have a polyfill pillow, try switching to foam, or better yet buckwheat. Polyfill is a dust sponge. Every time you toss and turn it will release a cloud of dust right by your face.

  You’ve lived this long with your dog, so it’s worth trying to find ways of improving your sleep hygeine and symptom management before jumping straight to no dogs. Although, a no puppies after this dog rule could be warranted.

  As far as not having some of the symptoms you think should be present, chronic exposure vs acute exposure can have different reactions. If you are always mildly reacting to your dog, then you won’t experience some of the acute responses. (Again, not a professional)

  You’re only making money if you downsize, move somewhere cheaper, or switch back to renting. If you move and all the other houses have gone up, then you just end up having to sink any gained equity into affording your new place. Rising prices really only help developers, realtors, and REIT’s.

• ⁨Comment⁩ on ⁨Eat lead⁩ ⁨⁨5⁩ ⁨months⁩ ago⁩:

  Yes, and lead is produced in much greater abundance than uranium.

  The part that’s missing in the post is in looking specifically at uranium deposits and making assumptions about the initial composition of the deposits, since the crystalline structure excludes lead when the crystals form. So if you detect lead contained within zircon, it is assumed to be the product of radioactive decay.
