    Unitedestadian has long been the term used to describe USA citizens by the Spanish-speaking population of the Americas. Not their fault the country picked a length intro title and a vague region as their country name. Imagine if the UK was the UKE, United Kingdom of Europe, and called themselves Europeans by default. The other 90% would be pissed and make their own names, no?






  • It’s typically this and not the particular tech in the headlight. And when it’s not “plug n play” (pnp) bulbs, it’s bad aim because every factory aims them with an empty tank and owners are clueless headlights can be aimed. That A8 had pretty good lights for the time. Sure, the lights do tend to be more intense when you’re in the beam on a hill, curve, etc), and the bluer color isn’t great for human night vision, but that’s a tradeoff for the increased speeds we travel at now.

    The further development of matrix LED lights by the Germans is a great development, really only feasible with LEDs. They turn off individual segments to give a near-high beam experience but specifically without blinding other drivers.

    But blaming it all on LEDs is like blaming gas engines for loud exhaust. There’s supposed to be a system in place that makes it tolerable for everyone around.



  • The Far Cry games pretty much always allow a sniper and/or stealth option. Some of the scripted mission sequences can be fast paced, but it’s largely open world. If you’re not familiar with them, stick to the games with numbers in the titles for starters. Probably not 6. Maybe not 2 this day and age. 3-6 all exist with a particular style in mind.

    Unless you’re anti ubisoft




  • Then I misinterpreted something from your comment saying Trump’s promise to increase water pressure (disregarding the impossibility) wouldn’t increase flow. Maybe you’re specifically talking about shower heads, but somewhere else trump talked about flushing toilets over and over. It all blends together in the insanity. Did he mention shower heads being too efficient, but in worse words?

    I agree, we’re generally in agreement then. I did specify stream vs shower setting though, and a kinda large jet outlet at that. Maybe more like a Full setting, in my experience, but I certainly am not including all the settings. Mist, vertical, center, etc are too restrictive. I’ve filled a couple dozen car wash buckets on various settings and shower/jet/full flow comparably then, but somehow always slower than my bladder can handle.


  • I started reading your comment and was going to add something about how I always see a deep misunderstanding of Bernoulli’s principle and… Well you have the same misunderstanding.

    Increasing pressure, with no other changes, absolutely changes flow rate. Bernoulli’s principle that effectively states as flow increases, pressure decreases (and vice versa) when the source is not changed. If the pressure at the source is increased and the flow rate is the same, then the entire system has more energy. Since the bottleneck is more likely to be the miles of pipes and hundreds of bends, flow rate can’t really be inherently increased but pressure can. I, in no way, am endorsing this EO or the insanity surrounding it.

    The proper application of the principle is at the outlet with a steady source. It’s best explained with a multi-setting garden hose. This is because the variable restrictor is exactly at the outlet. You can choose the stream setting which is high velocity but low flow rate - a single stream shoots across the street. You can choose the shower setting which is low velocity but high flow rate - a wide stream that only travels a few feet away. However, if you try to fill a bucket, you’ll likely find they fill at nearly the same rate, allowing for minor differences in nozzle drag and assuming the stream doesn’t cause too much drag (like a 1/8" outlet rather than a pin hole). Why? Because the system energy is the same, say 40psi with ample water supply for a garden hose where the faucet and preceeding piping is the restrictor rather than the outlet. At any point prior to the outlet, the pressure is the same and any setting would fill a very tall column to the same point at which pressure from the column equals pressure form the hose. So yes, realistically, bumping up the pressure would result in greater flow at the outlet, just as enlarging pipes, smoothing bends, and swapping high flow valves.

    But this is fucking batshit because the pressure has not been reduced and it’s not like we just have pumps we can tune to any pressure. The primary source is simply the height of water towers - the water towers that have been here for decades already. The most logical explanation I can give is the slow market change to high efficiency devices. But I’m gonna stick to the thought that the believers are retconning their memories. I mean, the fucking Simpsons have a scene where Bart fluctuates the shower temperature with just the sink faucet. Season 12, episode 12, Tennis the Menace, aired 2001.

    Your expat acquaintance couldn’t fix the situation because he wasn’t addressing the choke points. So many possibilities. Shitting routing in the house, shitty rerouting after a renovation, mineral deposits inside older pipes, longer routing in modern houses that are bigger with more bathrooms, false memories of the “before times” invented by Trump’s rambling, insufficient infrastructure as neighborhoods expand, or poor delivery system maintenance. Friendly reminder that there is a non-zero number of people buying into this while using household wells.




  • 3-point Seat belts go back to the 60s, disc brakes even earlier, anti lock was the 80s along with crumple zones, wishbone suspension goes back decades (including original Mustang) while being less commonplace now than the peak (90s?) where even BMW has gone with McPherson today. The biggest change in hybrid tech was the switch to lithium cells for appropriate power density, while there’s not much else new about electric motors and generators. See: diesel trains actually being diesel-electric. Maybe solid state components making DC voltage stepping feasible. There’s not anything actually wrong with drum brakes at this point. Modern pad material is the big thing, being able to withstand much more heat.

    I do not see how you consider those things major changes but not what has developed beyond that.
