For most of human history pee urine was left to get stale, turning it into ammonia, and used for doing laundry.

Washing clothes in ammonia is really great at getting out oil and grease stains. Though now you just buy ammonia directly from a good hardware store.


Hi, nerdy hacker here, could use further advice:

Can I screw the ammonia up, like how bleach ruins clothes? Any recommendation on amount? Do I add it to a wash cycle?

I have a lot of grease-stained shirts that are some of my favorites.


Don't mix it with bleach, otherwise you're o.k.

Can't really go wrong. After I do some bicycle repair, I toss my greasy clothes into the washer, and add a cup or two of ammonia during the wash cycle. I don't even add detergent, as the grease comes out without soap.

Mixing ammonia and bleach gets you basically mustard gas, so be cautious about what is in any other detergent you use at the same time...


Specifically it makes chloramine gas, the same stuff that (in fairly low concentrations) makes swimming pools stink. It can be lethal so definitely take it seriously, although it's not nearly so gnarly as real mustard gas.

Here's an incident where a woman inadvertently made chloramine gas in an enclosed space while cleaning and was breathing it for 30 minutes. It nearly killed her and she was hospitalized for a week: https://www.nejm.org/doi/full/10.1056/NEJM199909093411115


Here's one where a restaurant manager died after someone mixed cleaners right on the floor.

It's not mustard gas, but it is really nasty. It produces a mixture of chloramines and hydrazine.


Thanks for the clarification.


I only ever used it to clean floors, but word of warning: even a 3% solution is already noxious.

A whiff of Uranus so to speak.

Use in the laundry for regular stains: Soak stubborn stains on cotton, polyester, or nylon fabrics with a solution of 2/3 cup clear ammonia, 2/3 cup dish soap, 6 tablespoons of baking soda, and 2 cups warm water. Let it soak for about 30 minutes, then launder as usual. Never use ammonia on wool or silk.

Here's a step-by-step guide on how to wash clothes with ammonia:

1. Read the garment labels: Check the care instructions on your clothing items to ensure they can be safely washed with ammonia. Some delicate fabrics or certain colors may not be suitable for this method, so it's important to follow the manufacturer's recommendations.

2. Prepare the washing machine: Start by setting up your washing machine as you would for a regular load of laundry. Sort your clothes by color, fabric type, and level of dirtiness.

3. Measure the ammonia: For a typical load of laundry, use about 1/2 cup to 1 cup of ammonia. Adjust the amount based on the size of your load and the level of dirt or stains on the clothes.

4. Add the ammonia to the washing machine: Pour the measured amount of ammonia directly into the detergent dispenser or the main wash compartment of your washing machine. Be careful not to spill any ammonia on your skin or clothing.

5. Add detergent: Add your regular laundry detergent to the same compartment as the ammonia. The detergent will work in conjunction with the ammonia to clean your clothes effectively.

6. Start the wash cycle: Close the washing machine lid or door and start the wash cycle using the appropriate settings for your clothing items. Follow the machine's instructions for temperature, water level, and cycle duration.

7. Complete the wash cycle: Allow the washing machine to complete the cycle as usual. Once finished, remove the clothes promptly to prevent wrinkling or odor development.

8. Rinse the clothes: If you prefer, you can run an additional rinse cycle to ensure all traces of ammonia and detergent are thoroughly rinsed out. This step is particularly important if you have sensitive skin or are concerned about potential residue.

9. Dry the clothes: Depending on the fabric type and garment care instructions, dry the clothes by air drying, using a clothesline, or by using a dryer.

10. Clean the washing machine: After completing the load with ammonia, consider running an empty cycle with hot water and a cup of white vinegar to help remove any residual ammonia smell or build-up in the washing machine.

Remember to handle ammonia with care, follow safety guidelines, and avoid mixing it with other cleaning agents, such as bleach, as it can produce hazardous fumes. Always keep ammonia out of reach of children and pets.

Additionally, if you have specific stains or heavily soiled items, it's advisable to spot treat them before washing with ammonia.


The funny thing is, the classical art of Greece, probably looked much different than how we think about it. It was much more colorful and vibrant, it's just that all the pigment washed away. https://www.ancient-origins.net/sites/default/files/styles/l...

Cities adding art back onto the walls, is probably closer to how the ancient Greek cities actually looked. Our classical architectural view of pristine white walls is wrong. https://exploringgreece.tv/wp-content/uploads/2020/04/parthe...


Indeed, worse than that the myth of white statues as an aesthetic was created by racist euronationalists in the late 19th c. https://www.forbes.com/sites/drsarahbond/2017/04/27/whitewas...


I refuse to believe that the people who made some of the best ancient statues had an artistic sense of a 5-year old when it came to color...

Obviously ancient status were colored but probably in a much nicer way. No way something like:

https://static.frieze.com/files/inline-images/web-cg-h-102-a...

could be even close to the original ( considering that the Romans generally managed to somehow get skin tones more or less right in the few paintings that survived)


The problem is they do careful analysis of statues and find evidence of pigmentation, but obviously they're only looking at the remnants of the base coat and don't see any of the careful detailing that almost certainly went towards making these statues look very lifelike (judging by the realistic quality of the sculpture itself.) And so the recreations look flat and uncanny because they're essentially unfinished.


I wonder if another problem might be fashion trends. Sometimes bright, contrasting, colours are in style and feel normal. https://www.apparelsearch.com/terms/images/cher-aerobics-leg...


I don't think the bright colors are the problem, just the opposite actually.

Particularly in this example: https://static.frieze.com/files/inline-images/web-cg-h-102-a...

The bright clothes are fine, but his skin is awful. It's flat and lifeless, like a cold corpse drained of blood. It looks like they put the primer coat on then left it unfinished; I think that's literally what they did. Maybe this look is what they were originally going for, but I don't think so. Look at the detail on that guy's knees, they look just like real knees. I don't believe the original artists went through so much trouble to sculpt hyper-realistic knees then let some intern half-ass the paint job.


I think it's also current museum aesthetics where they do enough to give you the idea but don't want to take any artistic license beyond what's provable. So the painting could have been more subtle especially for those close to the viewer


Maybe you should reevaluate where your own aesthetic comes from https://www.forbes.com/sites/drsarahbond/2017/04/27/whitewas...

I think the reproductions suffer a bit because the distance these statues were from a viewer varied -- but just like murals


> Maybe you should reevaluate where your own

No, I don’t think so.

The way some of these “reconstructions” look is just plain awful. And based on the surviving examples of frescoes and paintings they would look as just awful the the Romans.

> I think the reproductions suffer a bit because

They suffer because there is no shading for one thing. The skin and hair especially just look awful. It has nothing to do with the bright colors (I get that part).


Manager of an investment fund is told to invest in social media, so they do so. Put a bit of money into each one.

Market's aren't rational.


Social media is great for groups to form, but there is a ceiling to the success.

You need a dedicated website/forum with people that understand the subject, to get though the ceiling. You get very specific advertisers, organize your own in person meetings.


A bleak Byzantine future, of endless bureaucracy.

Government reports continue to balloon in size, because of technological advancements (especially copy/paste).

In the age of typewriters, anything not important, or duplicate, was cut. With word processors, document sizes unnecessarily grew.


One thing that they share in common (Adam Curtis and James Burke), as well as Myth Busters, is that they have plenty of good footage/film (or whatever you call it).

Most news stories have 30 seconds of footage, and loop it repeatedly. No historical footage, no old interviews being brought up, nothing filmed to help put a story into context.

Even many documentaries I watch, suffer the same problem, a bit of real footage, then jumping straight to interviews with people. Not much historical footage, nothing extra filmed, expect interviews with people.


The unintended consequences of WWII are mind boggling. 78 years latter we are still seeing the social consequences playing out in demographics. A big Baby Boom, followed by a bust. Economists don't look at demographic models enough.


Don't forget that WW2 itself killed well over 50 million people, between direct casualties, civilians, the Holocaust and other genocides and war crimes, and starvation.


This stat probably includes older Americans in their 80s and 90s. Many immigrated in their teens, from small villages, in the early 1940s/50s. Let's say you left rural Italy in 1940, as an 11 year old. Started working in America at 16, in 1946. Many jobs in America at that time didn't require much literacy, for example working in a textile mill, or an assembly line.


Guilds would get the right to do something by the government, to the exclusion of others. Such as the haberdasher guild, that had the right to sew and no one else could sew commercially.

Patent was invented to break the guilds. A guild member could reveal a technology publicly, and get a 10 year right to use it. This was to make progress go faster, as guilds kept technology secret.


I like having 2 drives. This seems to only have a slot for one drive? It doesn't take too long until you end up with TBs of stuff.


You can put storage in one or more of the 4 expansion slots on the sides.


There are 6 slots on the 16.


What drives are the slots compatible with?


They sell their own 1 TB and 250 GB expansion cards. I've been using the 1 TB as my Pop!_OS system drive.
