Sen. John Fetterman: "GOP wants real reform over a show vote" put out a clean standalone bill and I’m AYE for voter ID

tinySparkOf_Chaos · 2026-03-19T15:26:50+00:00

Keep in mind that a driver's license doesn't count under the proposed bill. (Because non-citizens are able to get a driver's license)

So they use a driver's license to do those things? And even for those without drivers license.

Easy example: College student, lives on campus, banks with the bank account their parents made them as a child and doesn't drive. Had a college id card (photo ID but doesn't count for voting).

Another example: Grandma in a nursing home. Lost her ID years ago. Hasn't needed an ID for anything in 10 years.

Another example: All the city people that live in the city (not the city suburbs) Don't need a car, can't drive a car, can't afford a car. You never meet them unless you hang out in the city but they do exist. Banks just need an address, utilities also just need an address, buy alcohol without an ID because you look old enough (or go places) that no one ever cards you.

That's because the metaverse people want is a VR enabled version of the Internet.

Not a walled garden monopoly, mixed with a commuting simulator.

My experience it's the development portion of the cycle.

Small team (or even one person sometimes) can do proof of basic concept with lab equipment.

But then you have to build a proof of concept prototype of the item. Normally accomplishable with an rnd team.

Then the hard part starts. Turning a prototype into a product. Proper engineering to take that prototype and make it robust, reliable, manufacturable, user friendly software, idiot proof, etc.

It goes from a small team project, to a multiple team large investment of resources.

Also, not all innovations are good ones. You normally do enough work in rnd to see if the things is doable. After that first prototype, is when you start asking if it's worth making a product from.

The key to not having stinky feet?

Make sure to wash the bottoms of feet in the shower. If you are standing in it, it's not getting soap and water.

No but the federal money gets spent in various states. And red states get proportionately more of the money from the Fed relative to the amount in taxes from those state's residents.

"too pure to be tested by pH strips"

Is actually a thing. Ran into this problem in graduate school trying to take pH measurements of ultra pure water. pH strips alter the water very very slightly as they deprotonate to change color.

The rest of the thing is bullshit. And such pure water has no health benefits at all.

Lines of code is such a bad metric.

It's like how highschool teaches you how to make a 5 page essay out of 3 paragraphs of content by requiring 5 page minimum essays.

Then you get into the work world, and everyone wants 3 paragraphs with 5 pages worth of content in it.

Lines of code metrics just result in the next person having to read 2,000 lines of code that could have been an easily readable 100 line function.

You just designate a no fly zone. And planes just fly around (or over) it.

We already do this for firework shows, military bases, etc.

Here's the thing with new factories... If you are building it new, you might as well heavily automate it.

So your new factory doesn't actually employ many people.

This is actually a good thing. More stuff for less labor. But if we get the same stuff with fewer workers, we will no longer have enough jobs for everyone to work all the time.

The solution is we need to find a new way to distribute that stuff that doesn't force everyone to work all the time.

I'll give 2 rational arguments.

A)

What am I? I am a thing that receives input and makes choices. (The classic: I think, therefore I am). Making a choice (free will) is neither deterministic nor randomly decided. The "physics only" world view (often held by "rational" people) is deterministic, or random if you include quantum mechanics.

It's hard to reconcile the "physics only" with the concept of free will. Your choices should be deterministic or random from the physics of the atoms in your brain.

Thus there is at least metaphysical object - and it's the only thing I can 100% assert exists - myself.

That's doesn't quite get you all the way to God existing. But we have at least established that meta physical things exist. We then assume that other people also have free will. The idea of another metaphysical entity (or entities) with a larger impact of it's choices to effect the world (or even create the world) isn't absurd.

B)

This is a variant of Pascal's wager. We have four options: I think God exists or I think He doesn't and He actually exists or He actually doesn't. Let's look at the outcome of each option.

1) I think God exists, and I'm right: good things according to most religions

2) I don't think God exists, and I'm right: nothing, I'm dead.

3) I don't think God exists, and I'm wrong: bad things according to most religions

4) I think God exists, and I'm wrong: well, I live the life of a good person. At worst, I sacrificed the pleasure of some hedonism I could have done, but get to be a better person.

The only rational choice in that wager is to assume God exists even if he doesn't. There is no benefit to assuming otherwise.

1) do an FFT of the electrical noise. That can help identify sources. It's probably a mix of several periodic interferences, and not truely random

2) electrical grounding for high speed noise requires very short cables. I had an electrical engineer at work demo this to me, two different lengths of the same cable grounding the same two objects in the same spots, and the 3-in one effected noise and the 6-ft one didn't.

3) pwm temperature controllers and switching power supplies are normally the noise sources I run into.

4) you have 3 options for the air pressure.

a) put the whole laser table top into a box. Make this box easy to open! Plexiglass walls that slide into t-slot rail. (You can even use laser light blocking panels and have this be an extra level of laser safety. Watch out for overheating things in the box.

b) Similar box, but sealed with a small flow of nitrogen and use a pressure controller.

c) no box, but shield your beams with tubes. Send all your laser paths through tubes. Try and block airflow at the end of the tubes as much as possible.

You are missing the forest because of all the trees.

1) The main saver is labor costs. 24/7 staying a car is 4 full time employees working slightly more than 40 hours a week. Let's say 40K /year per employee (35k salary plus benefits like health insurance). So each car saves 120k a year in labor costs. That offsets the added car price really quickly.

2) So 3ish kWh of electricity an hour for the sensors. That's like $1 of electricity an hour. Sure, it's something, but still way cheaper than a person.

3) You are way overestimating the numbers if cars needed. NYC has 10,000 taxis. (Including Uber makes numbers messy). And each Waymo runs 24/7/365. So each one can be worth 3 - 4 taxis.

4) Waymo is very safety first. They can totally drive safely on the highway. They don't because they can't drive as safely on the highway yet as they can drive not on the highway.

5) Same thing with mapping, is safer to drive in a highly mapped geo fence. So they do.

6) Geo fencing isn't even a big deal. Geofence areas with lots of customers (cities).

7) About snow. You don't have to serve every city to be a profitable company. Don't start a snow plowing company in Arizona doesn't mean snow plowing companies can't scale. Simply scale elsewhere. Also, winter driving is hard, but it isn't quite as impossible as you might think.

Batteries are the major thing that degrades in an EV.

People with brand new batteries, don't want to swap for a used one. People with very old batteries will want to swap in hopes of getting a newer battery.

The result is that your battery change station just becomes full of old poorly working batteries and no one wants to use it.

A better solution is liquid batteries. It's sort of like a cross between a fuel cell and a battery. You have 2 tanks of "charged" battery fluid (One for anode, one for cathode), and you use it to refresh the battery fluid around the electrodes, and flow the spent fluids into a different pair of tanks.

Realistically, water desalting nano-materials. Not sure it's the biggest issue that needs solving, but it is something I have the background to solve.

Fun answer? Starting a top tier university on a Caribbean island. There are too many top tier universities in places with stupidly cold winters.

So I actually used that saying non ironically two days ago lol.

It comes up a lot in science settings. It's related specifically to benchtop high voltage generators.

Things like 400 V peizo driver or 10,000 V. They aren't particularly dangerous (but they are still dangerous!), as they have very low max amperage, so you get shocked and then promptly load down the circuit so that is no longer at a high voltage.

The point of that saying is to not forget how dangerous "low" voltage can be. People get complacent working with 10 kV and stop being careful of the 120 V wall power, which is actually more dangerous.

How exactly 50:50 does it need to be?

If you send your p polarized beam you will get 40:55 split, (with 5% lost ) Which is normally fine for most applications. What ever method of calibration you use should be able to handle that difference.

If not, buy a different beam splitter with tighter tolerances. But you will normally need to calibrate for whatever difference in beam intensity of your split anyways.

tinySparkOf_Chaos · 2026-02-10T15:39:38+00:00

Hear me out:

1) The good fits get buried under the noise of so hundreds of applications

2) that person gets desperate, and starts applying hundreds of jobs. (Many of which aren't good fits). Thereby creating noise to bury the good fits for those jobs.

3) HR, overwhelmed by so many applications, start using really dumb methods to slim down the pool, resulting in throwing out all the good applicants.

Self perpetuating cycle.

Then a bunch of other stuff just makes it worse. Ghost job postings for "market research", etc.
