so: masking: good, unequivocally. please mask and please educate others on why they should mask to make the world safer for immune compromised people to participate in.

however: masking is not my policy focus and it shouldn't be yours, either. masking is a very good mitigation against droplet-born illnesses and a slightly less effective (but still very good) mitigation against airborne illnesses, but its place in the pyramid of mitigation demands is pretty low, for several reasons:

it's an individual mitigation, not a systemic one. the best mitigations to make public life more accessible affect everyone without distributing the majority of the effort among individuals (who may not be able to comply, may not have access to education on how to comply, or may be actively malicious).

it's a post-hoc mitigation, or to put it another way, it's a band-aid over the underlying problem. even if it was possible to enforce, universal masking still wouldn't address the underlying problem that it is dangerous for sick people and immune compromised people to be in the same public locations to begin with. this is a solvable problem! we have created the societal conditions for this problem!

here are my policy focuses:

upgraded air filtration and ventilation systems for all public buildings. appropriate ventilation should be just as bog-standard as appropriately clean running water. an indoor venue without a ventilation system capable of performing 5 complete air changes per hour should be like encountering a public restroom without any sinks or hand sanitizer stations whatsoever.

enforced paid sick leave for all employees until 3-5 days without symptoms. the vast majority of respiratory and food-borne illnesses circulate through industry sectors where employees come into work while experiencing symptoms. a taco bell worker should never be making food while experiencing strep throat symptoms, even without a strep diagnosis.

enforced virtual schooling options for sick students. the other vast majority of respiratory and food-borne illnesses circulate through schools. the proximity of so many kids and teenagers together indoors (with little to no proper ventilation and high levels of physical activity) means that if even one person comes to school sick, hundreds will be infected in the following few days. those students will most likely infect their parents as well. allowing students to complete all readings and coursework through sites like blackboard or compass while sick will cut down massively on disease transmission.

accessible testing for everyone. not just for COVID; if there's a test for any contagious illness capable of being performed outside of lab conditions, there should be a regulated option for performing that test at home (similar to COVID rapid tests). if a test can only be performed under lab conditions, there should be a government-subsidized program to provide free of charge testing to anyone who needs it, through urgent cares and pharmacies.

the last thing to note is that these things stack; upgraded ventilation systems in all public buildings mean that students and employees get sick less often to begin with, making it less burdensome for students and employees to be absent due to sickness, and making it more likely that sick individuals will choose to stay home themselves (since it's not so costly for them).

masking is great! keep masking! please use masking as a rhetorical "this is what we can do as individuals to make public life safer while we're pushing for drastic policy changes," and don't get complacent in either direction--don't assume that masking is all you need to do or an acceptable forever-solution, and equally, don't fall prey to thinking that pushing for policy change "makes up" for not masking in public. it's not a game with scores and sides; masking is a material thing you can do to help the individual people you interact with one by one, and policy changes are what's going to make the entirety of public life safer for all immune compromised people.

In the realm of civil engineering and materials science, quality assessment and control is paramount to ensure the safety, longevity, and structural integrity of constructions. One essential tool in this endeavour is the Sieve Analysis Test.

This test plays a crucial role in determining the particle size distribution of aggregates, both coarse and fine, offering insights into the material's engineering properties.

In this comprehensive article, we delve into the intricacies of the Sieve Analysis Test, exploring its purpose, advantages, disadvantages, uses, and related concepts, and providing a step-by-step guide to its execution.

Understanding the Sieve Analysis Test

The Sieve Analysis Test, often referred to as the Gradation Test, is a fundamental procedure used to quantify the distribution of particle sizes in aggregates. Aggregates, including materials like sand, gravel, and crushed stone, constitute the foundation of various construction projects, including roads, buildings, and other critical infrastructure.

The properties of these aggregates, particularly their particle size distribution, significantly influence the workability, strength, and overall performance of concrete and other construction materials.

The Sieve Analysis Test involves passing a sample of the aggregate through a series of progressively finer sieves (meshed screens), each having specific sieve openings. As the material is sieved, particles larger than the sieve openings are retained on the sieve, while smaller particles pass through.

The resulting data offers valuable insights into the grading of the material, which is the distribution of particle sizes within the aggregate.

Advantages of the Sieve Analysis Test

The Sieve Analysis Test provides several advantages that contribute to its widespread usage in the construction industry:

1. Quality Control

Construction projects require a high level of quality control. By analyzing the particle size distribution, engineers and quality control personnel can assess the consistency and quality of aggregates. This helps ensure that the aggregates used in construction meet the required specifications, minimizing the risk of structural failure and enhancing the overall durability of the project.

2. Performance Prediction

The particle size distribution of aggregates has a direct impact on the properties of concrete and other mixtures. Engineers can use the Sieve Analysis Test results to predict the behaviour of these materials in real-world applications. This information is vital for designing mixtures with optimal workability, density, and strength, ensuring the long-term performance of constructed structures.

being aromantic is like. hey btw you're going to live a life that is the culmination of most of society's worst nightmares. sorry lol ✌️ but then you turn around and take a really good hard look at it and it turns out that living in that nightmare is fucking awesome and you get to wake up every day and take that fear that other people have and laugh and hold it close until it's a great joy for you instead. and being happy is a radical act that you define instead of someone else. and you're sexy as fuck that's just a fact of life i don't make the rules on that one

Secure-Lock Steel-Skinned Structural Insulated Panel System

Secure-Lock Structural Insulated Panels (SIPs) are high-performance building panels for floors, walls and roofs in residential and commercial buildings. Structural Insulated Panels use expanded polystyrene (EPS) foam insulation sandwiched between two structural skins of steel (used in the patented Secure-Lock panel). The result is a building envelope system that is hurricane, seismic, fire, pest and mold-resistant, as well as energy efficient, fast to erect, and cost effective.

Okay so I have a lot of thoughts about the whole thing of the Gerudo being a race of entirely women, with the only exception being one man born every hundred years, and that man automatically being their king. Now this worldbuilding comes from Ocarina of Time, and there's obviously a metric fuckton of unfortunate implications there, because it was 1998. And it seems that Tears of the Kingdom is sticking with the lore of Gerudo men being extremely rare and becoming the King of their people, which once again has a metric fuckton of unfortunate implications because it's 2023 and Nintendo has somehow gotten even worse about this shit.

But let's set aside the whole... everything, and look at this from just the in-universe perspective. How does it work? I mean, it's pretty clear that there is no overlap between the kings; the old ones are normally long gone by the time a new one is born, but the Gerudo manage to take care of themselves during the hangtime. So they must have an established system of government and leadership that doesn't involve a king, and somehow that system is set up in a way that does a smooth transfer of power once a new king is born and old enough to take the throne. But why bother always declaring a random guy to be your King when you already have a perfectly functional system in place?

I mean again, the whole thing has a lot of sexist implications, but we're not looking at this from a real world context, we're examining it in-universe. And we could just go the lazy route and say that their king is in charge just because he's the only man, but I don't like that. I mean come on, the Gerudo are a race of entirely women, and most of their outside problems come from Hylian men being creepy about it. They are entirely a matriarchy; there is literally no reason for their culture to have an inherent respect for men, even if the man in question is one of them. And they're desert people; they live in an extremely harsh and dangerous landscape, if they don't have their shit together, they will die. By sheer necessity, their culture needs to put a lot of value in being practical, because if they're stupid about things, people die. They really can't afford to have a shitty leader take over, and just letting some guy take the wheel doesn't really fit with the way their culture must otherwise work.

So again, why the fuck do they bother having a King?

I think it's mainly just a ceremonial position. Yes, if the guy is a good leader he'll be in charge, but if he isn't good at being a King or isn't interested in the job... fuck it, they've already got a functional government system that's been leading their people the whole time, why fix what isn't broken? The title of Gerudo King isn't about leadership or power. I think it's more about belonging. Because the Gerudo are a culture where every single one of them can be defined in the same way... and there is exactly one exception once a century. Men are considered to be inherently outsiders at the best of times, and more often they're enemies. A man born into this culture is a natural outsider; he is completely unique, and that means he doesn't really fit into his community. And well... when someone is fundamentally different from the rest of their community, they tend to be ostracized.

So I think that's why the position of Gerudo King exists. It isn't about them needing or even wanting a man to lead them. The title of King doesn't need to involve any leadership at all. It's about giving the man born every century a place in their society. It's a way of saying yes, you are one of us, you are a Gerudo, you belong here, you are wanted and you are loved.

The Gerudo know that every hundred years, one of their children will be fundamentally different from all of his peers. And so their society is built to ensure that a child who is completely different from them will still be loved and accepted. He will always have a place in their society. He doesn't need to earn their love, he has it just for existing. These are his people.

The title of Gerudo King isn't an inherent position of authority. It's a promise of acceptance.

Crafting Future From Ruins: A Writer's Guide to Designing Post-Apocalyptic Technology

Photo: Standard License- Adobe Stock

Crafting post-apocalyptic tech involves blending creativity and realism. This is a guide to help you invent tech for your post-apocalyptic world:

Tinker, Tailor, Writer, Spy: Start with modern tech. Take it apart (conceptually or literally if you're feeling adventurous). Using the basics, think of how your character might put it back together with limited tools and resources.

Master the Fundamentals: Understand the basic principles underlying the tech you're working with. Physics, chemistry, and biology can be your best friends. This understanding can guide your character's resourceful innovations.

Embrace the Scrapyard: The world around you has potential tech components. Appliances, vehicles, infrastructure - how could these be deconstructed and repurposed? Your characters will need to use what's at hand.

Cherishing Old Wisdom: Pre-apocalypse books and manuals are the new internet. A character with access to this knowledge could become a vital asset in tech-building.

I think one of my favorite things abt all systems red in hindsight is that it’s not written like a letter. At all. Probably bc murderbot has no experience with letters but it has read a ton of books so it wouldn’t really know how a letter is structured. So instead it just kind of told her everything 😭

[coquelicoq]

we get a lot of really great stuff in system collapse about murderbot's relationships with ART and ratthi, which makes sense, because it spends almost the entire book with them. but i also love how even though mensah isn't there for most of the story, other people keep reminding mb of her:

chapter 2, page 25: “From ART’s personnel file, she [Karime] was older than Mensah and she didn’t look like an intrepid space explorer, either, even in the protective environmental suit.”

2, 27: “It took Karime three seconds to process the abrupt statement. (She was almost as good at not looking annoyed as Mensah was.) She kept her expression neutral and patient.”

2, 28: “In the underground colony room, Karime lifted her brows. ‘Another occupied site?’ I thought she was being careful not to show too much reaction. It was the way Mensah would have played it.”

4, 70: “Iris looked at me and I saw her hesitate, because her hesitation looked a lot like Dr. Mensah’s hesitation. And I realized I really didn’t want to go down there.”

5, 104: "Iris has that same thing as Dr. Mensah, the thing where she’s able to look and sound calm under circumstances where shit is possibly about to go down.”

it's spent so much time with her and it knows her so well and respects her so much that she's the model against which it compares all other humans. it thinks about her when they're not together. it's protective of her. it has such total faith in her competence. it (non-romantically) loves her and doesn't want to not see her again. idk man, it just gets to me! and they were teammates (oh my god they were teammates!!)

bonus:

I said, aloud, "You have to be kidding me." (ch. 2, p. 28)

seven pages later, in reaction to the same thing:

Mensah had had time to review the feed video. She muttered, "Oh, you have to be kidding me." Yeah.

Tired of seeing North American election politics on my dash and the only thing I'll say about it is that it was a seriously bad move to not have compulsory voting for all citizens. Part of being an adult is making hard decisions and getting to opt out of that by legally not voting is not the gotcha that a lot of people think it is.

[knifearo]

this year my challenge for everyone is to unlearn the association between love and morality. love is not something that is inherently morally good, and the absence of love is not something that is inherently bad. sex without love isn't morally bankrupt, it's just an action. people without love aren't less kind or less good, they're just people. when we can get past this false (and often unnoticed) dichotomy of good love/evil lovelessness then i think we are going to be able to take leaps and bounds in sex positivity, aro advocacy, certain discussions of mental health...
