  • It means there are two separate chemicals inside of the building. Each chemical would have their individual labels on their containers, but these external signs are for first responders who haven’t entered the building yet.

    Let’s say there’s a fire. The red diamond tells them how likely it is that the chemicals are the cause of the fire, and where they should direct their efforts. The blue corner tells them what kind of PPE they need to use if they enter. The yellow tells them what kind of potential explosive risks the chemicals have. And the white one is especially important, because the W means the chemical reacts with water; If there’s a fire at the facility, they can’t simply use fire hoses to fight it.

    The reason for listing them separately is because each individual chemical has its own ratings. You can’t simply take the highest of each and combine them into a single sign. For instance, in this case one chemical isn’t flammable but is explosive when heated. The other chemical is flammable but not explosive. So if you see a chemical on fire, you know it’s the second chemical and isn’t explosive. But if you see something that isn’t burning in a room full of fire, you know it’s a potential powder keg waiting to explode.


  • Those are hazardous chemical markers. You commonly see them on tanker trucks as well.

    The numbers range from 0 to 4, with higher numbers indicating more risk. The red top corner is flammability. The right yellow corner is instability; How likely it is to react with other things around it. The left blue corner is risk to health; Even if a chemical isn’t unstable or flammable, it can still be hazardous. The bottom white is for special markings. In this case, one of those chemicals is marked with a W, meaning it reacts to water.

    So if there’s a fire at the warehouse, this tells the responding crew “hey just so you know, there’s some nasty shit in here. One presents a severe health hazard, becomes potentially explosive when heated, and reacts with water… But at least it isn’t flammable. The other is flammable and can present a moderate health risk. Because of the one on the left, it would be a bad idea to use water to fight this fire.”




  • In a scenario where things are so bad that the US has halted all financial electronic transactions than your electronic dollars don’t mean anything no matter where you are, amd your paper dollars mean almost nothing either.

    This is honestly the biggest takeaway. If the US actually stops cooperating with foreign banks, the dollar will instantly become worthless; The dollar only holds international worth because other countries want to have and hold dollars. If those other countries are unable to do so, there is no incentive for them to accept dollars as valid currency.




  • To be precise, that’s a cogwheel. There are six cogs around the cogwheel in your image. The word “cog” refers specifically to the teeth around the wheel, not the wheel itself. The cogwheel may be colloquially called a cog, but it’s technically inaccurate; If you told a watchmaker that their watch was missing a single cog, it would have a very different meaning than if you told them it was missing a single cogwheel.





  • This is the worst way to go about doing it, because you should never assume a drawing is made to scale unless it is specifically marked as such. A protractor would be useless if the drawing isn’t to scale. Generally speaking, if a problem isn’t drawn to scale, it’s because all of the info you need to solve it is already present in the drawing. You don’t need to bust out the protractor to measure angles, because the angles can either be calculated from the available info, or aren’t needed in the first place.


  • Isn’t Gunzilla Games the company that released a bitcoin miner disguised as a mobile game? I swear I remember seeing something about them being banned from the various app stores for trying to bury miners in their shit, but a basic google search didn’t find anything.

    Edit: It looks like they’re trying to use blockchain to mint in-game items as NFTs.

    This is how it works in Germany. Lots of their water bottles are made of glass, and end up with textured/worn rings along the bottle; The rings are from where it goes through the recycling machines to get prepped for the next use. The rings mean the bottle has been reused a lot, and has gone through the machines enough to get slightly worn.
