UPDATE: NOVAVAX NOW AVAILABLE!!!

Hi everyone, it's been about a year since I posted about updated COVID vaccines and it's time for another update if you are in the US:

THE BRIDGE ACCESS PROGRAM IS ENDING!!!!

If you are uninsured or your insurance does not cover covid boosters, please schedule a new booster appointment before the end of August because the Bridge Access Program (the way the government will still pay for your booster) ends in September. The updated mRNA boosters from Moderna and Pfizer are available now. Go Go GO!!!

Shitty, I know! If you can call your congressional reps, the FDA, the CDC, whomever to tell them you want this program to continue/be reinstated, that would be great. Also, while you're at it, call the FDA to tell them to expedite the approval for the updated Novavax booster (3017962640).

The new Novavax vaccine is designed for the JN.1 strain which is one of the most recent mutations of the virus going around. If you have insurance and can afford to wait, I highly recommend getting the Novavax booster when it becomes available.

We are currently in the largest Covid summer surge since 2021

If you haven't had a booster in the past six months you are essentially unvaccinated. New strains with different spike proteins keep evolving faster than vaccine development and distribution can keep up. All that said, getting Covid is not a moral failing. If you do feel sick, take a rapid test! If it's negative, test again a day or two later. It is better to know than not to know. Here's a refresh on how to take a rapid test correctly:

If you do get Covid, it is worth getting on antiretrovirals within the first week of symptoms to reduce the overall viral load your body has to fight. If your insurance doesn't cover Paxlovid or Remdesivir, here are other low/no-cost ways to access it:

If you get sick, rest radically even after you stop testing positive on rapid tests. Avoid exercising for at least eight weeks after the fact to reduce the risk of developing long covid.

Regardless of your vaccination status, masking with a KN95 or N95 respirator (or equivalent standards in your country i.e. FFP2/3 in the EU) is the most reliable way to protect yourself and others. If Covid protections are a financial burden, there is likely an active Mask Bloc near you doing free distribution of respirators and tests that would be happy to help you. Here's a global map of them from covidactionmap.org

Some quick tips: if you're wearing a bi-fold mask, flatten the nose-bridge wire completely, then mold it to your nose on your face for a better fit. The best mask is the one that you will actually wear regularly to protect yourself. I really like the selection of styles, sizes and colors from WellBefore:

As school is starting, getting you and your family boosted is one of the best things you can do to protect yourselves. Masking is perhaps even more important. If you can advocate for updating and regularly changing the HVAC filters at your local schools to MERV-13 or higher to keep the indoor air cleaner, that can also make a big difference. Better indoor air quality in schools helps protect kids from illness, allergies, wildfire smoke, and more per the EPA's website.

These are steps you can take to improve air quality at home as well. Corsi-Rosenthal boxes are low-cost and highly effective for cleaning the air indoors.

Here's a map of clean air lending libraries for getting access to air purifiers for events from cleanairclub.org

The Global HVAC System Market is projected to grow at a CAGR of around 6.5% during the forecast period, i.e., 2023-28. The market growth is driven by the changing climatic condition resulting in hot and harsh weather in numerous regions, raising consumers' demand for air cooling. Besides, the industry will likely flourish positively since HVAC systems are essential for maintaining comfortable indoor environments in residential, commercial, and industrial settings.

As someone who works in the reliability sector of IT I cannot emphasize how much you have to give 0 fucks about professional standards and best practices in order to do something like what Crowdstrike did.

At the company I work for, which you have definitely heard of, there are thousands of people (including me, hi) part of whose job it is to sit in rooms for literal hours every week with the people building new features and updating our software and ask them every question we can possibly think of about how their changes might impact the overall system and what potential risks there are. We brainstorm how to minimize those risks, impose requirements on the developers, and ultimately the buck stops with us. Some things are just too risky.

Many of the practices developed at this and other companies are now in wide use across the industry, including things like staggered rollouts (i.e. only 1/3 people get this update at first, then 2/3, then everyone) and multi-stage testing (push it to a fake system we set up for these purposes, see what it does).

In cases where you’re updating firmware or an os, there are physical test devices you need to update and verify that everything behaves as expected. If you really care about your customers you’ll hand the device to someone who works on a different system altogether and tell them to do their worst.

The bottom line here is that if Crowdstrike were following anything even resembling industry best practices there should have been about twenty failsafes between a kernel bug and a global update that bricked basically every enterprise machine in the world. This is like finding out the virus lab has a direct HVAC connection to the big conference room. There is genuinely no excuse for this kind of professional incompetence.

truly busts my gut when i read like "wow SOME OBSESSIVE people think we should LOCK DOWN FOREVER until there is ZERO COVID which is IMPOSSIBLE and there are LOTS OF ILLNESSES THAT RUIN YOUR ORGANS NOT JUST COVID so in fact maybe YOU ARE ABLEIST for appropriating ACTUALLY DISABLED people's CONCERNS" like... (a) honey anyone isn't disabled until suddenly they are and (b) i thought we tested this kind of zero sum fatalism on global warming and found it super unhelpful or...?? why are we jumping to lockdown??? my bro... my buddy... there are...things called masks...that u can wear when ur sick or in close quarters... there are these things called air purifiers... hvac systems...air filtration... omg and things called windows, and when you open them, less people get sick. any kind of sick! isn't that crazy. absolutely wild. i, a teacher of small children, certainly cannot do lockdown and have no interest in doing lockdown and certainly only did it for about 3 weeks, but i can... open the windows? wear a mask? so my children get less organ damage and their teacher can teach them all year instead of going on medical leave? and even if i were not disabled i would still open the damn windows because i would rather my students and i not get any kind of sick...? also brains don't work as well when the air doesn't circulate? the real issue is air quality? this is not a huge drama?

"we had the black death therefore we shouldn't do anything about covid" DO YOU THINK PEOPLE DID NOTHING ABOUT THE BLACK DEATH. do you think people saw cholera and were like, hmm i love shitting my soul out of my body, let's not do anything about the water?? we'll just naturally learn to digest feces??? what is going on here. just find whoever annoyed you annoying like a normal person. it doesn't have to be ideological war.

Because I love coral reefs I am hoping to create a beautiful coral reef planet full of them. A few things that are on my mind. Obviously, coral reefs only grow in tropical areas, which should probably exclude the poles. That's fine. So a few questions on that. What is the best way to extend the tropical range? What is the narrowest possible temperature range between equator and pole? How well can I do if I diversify my corals with plenty of heat or cold resistant coral? What characteristics do those corals need? Also, this is very much a living and evolving planet so I have questions on how these coral reefs have changed over the different periods What would make the current period long-lasting and not have had the last mass extinction too soon? I want certain coral species to be ancient and have survived multiple mass extinctions. How can I design those?

Addy: I did some searching, but I'm no climate-dinosaur expert, so the best I've got for you are some rough outlines of our own planet's history.

We've had many coral reefs over the eons - the largest (from my understanding) were during the late Devonian period, but they were actually made of different creatures than what make up our modern reefs. They died off, though, and our modern corals took their place. Those modern corals really took off during the Cretaceous period, so I'm looking at that for climate stuff.

The Cretaceous period had high water levels (~300+ ft above modern sea level), which meant that you had large, shallow stretches of ocean over areas that would otherwise be land. The poles didn't have ice caps (average polar water temperature was around 40°F), and Antarctica was covered in forests.

You did have periodic oxygen deprivation events, but you could probably prevent those by introducing some more currents into your oceans. Our Cretaceous period had some pretty clustered continents, which, to compare it to HVAC, meant that they didn't get a lot of ventilation. Really easy for it to get stuffy in a room without ventilation… or to use up all of your oxygen and suffocate. So! Make the areas a bit less clustered, give your continents a bit more room to breathe. Open a metaphorical window. That'll help prevent mass extinctions.

For land temperatures… from what I could find online, the areas within the latitudes from the equator to ~10° were tropics, the 10°-30° latitudes were arid subtropics*, the 30°-45° latitudes were humid subtropical with moderate/heavy rainfall, and then the polar regions were temperate.

* Might be from the oceans getting squeezed like that, not much room for the winds to pick up ocean spray

A couple useful links:

https://www.climate-policy-watcher.org/global-climate-2/cretaceous-era.html shows some specific temperatures for certain regions

https://www.bgs.ac.uk/discovering-geology/fossils-and-geological-time/corals/ info about corals

https://www.britannica.com/science/Cretaceous-Period info about the Cretaceous period

So if you've got a warm planet with large regions of shallow ocean, then you've got a coral-happy environment. We have sections of modern Earth that are like this, but they're only sections. Cold-resistant coral are going to live a bit deeper in the ocean, and are a sort of bastion of safety when ocean temperatures rise. They don't support the same marine species as the shallower reefs, but the cooler temperatures they live in are generally safer during periods of global warming (which we're seeing again now, as the planet warms).

Certain coral species to survive… I'd say that you'd get family lines that'd survive, that's easy, no problem. Whatever didn't die in the last mass extinction lives on, and its offspring will be whatever species come next. If you want it to be an exact species, then you'd probably need to have the last extinction to have happened relatively soon. If you're just looking for something that looks similar and acts pretty much the same, then it can have happened however long ago, no issue.

Eco-Friendly PVC Curtains: Reducing Your Carbon Footprint

In today’s world, businesses are increasingly looking for ways to reduce their environmental impact and operate more sustainably. One often overlooked yet effective solution is the use of eco-friendly PVC curtains. Modern PVC curtains, especially those made from recyclable materials, can play a crucial role in reducing waste and lowering the carbon footprint of businesses. From cold storage facilities to industrial workshops, these versatile curtains are helping businesses maintain energy efficiency and reduce their environmental impact without compromising on quality or functionality.

The Role of PVC Curtains in Environmental Sustainability

PVC curtains are traditionally made from Polyvinyl Chloride, a durable plastic material known for its flexibility, resilience, and long lifespan. However, concerns about the environmental impact of plastic have led manufacturers to explore more sustainable options.

Modern eco-friendly PVC curtains are now being produced from recyclable materials. By using recycled PVC, manufacturers can reduce the demand for new raw materials and lower the amount of waste that ends up in landfills. This approach not only helps in minimising the environmental impact of the production process but also provides businesses with a sustainable alternative to traditional plastic products.

Recyclable Materials: A Step Towards a Greener Future

Eco-friendly PVC curtains are designed with recyclability in mind. At the end of their life cycle, these curtains can be recycled and repurposed into new products, helping to create a circular economy where materials are reused rather than discarded. This helps businesses minimise their waste output and contributes to global efforts to reduce plastic pollution.

In addition, the production of recyclable PVC curtains typically uses less energy compared to manufacturing new PVC from raw materials, which helps to lower greenhouse gas emissions. By opting for these eco-friendly alternatives, businesses can significantly reduce their carbon footprint while still benefiting from the durability and functionality that PVC curtains offer.

Energy Efficiency and Carbon Reduction

One of the most significant ways that PVC curtains help businesses reduce their environmental impact is through energy efficiency. In cold storage units, for example, these curtains prevent the exchange of warm and cold air, reducing the need for constant refrigeration and helping to lower energy consumption. This energy-saving benefit translates to lower greenhouse gas emissions, as less energy is needed to keep facilities at the desired temperature.

Similarly, in manufacturing plants, warehouses, and other industrial settings, PVC curtains can help to maintain specific environmental conditions without requiring heavy-duty air conditioning or heating systems. By creating barriers that regulate temperature, they reduce the workload on HVAC systems, further contributing to energy efficiency and lower carbon emissions.

Oh, we're ragging on schools?

Mine had fucking CLIMATES

Some parts of the building, either the heating or the AC would always be stuck on, no matter what time of year it was. In some parts of the building neither the heating or the AC could ever be turned on. In other parts the heating or the AC could be turned on, but not the other. In most of the building, the heating and the AC could be turned on whenever the central system was working correctly, which was not consistent.

Add a uniform and teachers who decided that windows remain open or closed based on their preference, not the temperature of the room or how distracted it made the class...

Oh, and I still don't know why some of the rooms had different humidity than others

And the thing of it is... I don't think anyone should expect schools to have 100% pristine HVAC.

But it should be in a state of homeostasis so students can focus on learning and not worrying about suffering every permutation of global warming in a single school day!
