Technically, its only a hamburger if it comes from the hamburg region of Germany. Everything else is sparkling beef.
- Comment on Odds of rolling a 7 with a weighted die 5 days ago:
If a die is weighted, the first roll is no longer 1/6 probability to get a 7
Yes, actually, it is. No matter what the first die lands on, there is a 1 in 6 chance that the second die will land on the corresponding value necessary for a “7”. You could glue the first die to the table with “6” (or any other number) showing, and there will be a 1 in 6 chance that the second die will bring the sum to 7.

- Comment on The "standard" car charger is usually overkill—but your electrician might not know that [32:26] 6 days ago:
Wat. Do you think there’s like a L1.5 or something?
There’s the option of a level 1 charger at home, supplemented with an occasional stop at a fast charger.
The L1 charger is not quite enough to keep up with their usage, but their usage isn’t enough to make an L2 absolutely necessary.

Can you cite a time stamp? I don’t want to watch a 30 minute video.
I’m very curious where “42 amps max” comes from, as NEMA outlets are rated for 15A, 20A, 30A, 50A, or 60A. 42A is a rather oddball number; I’d like some context for it.
Most dryer outlets are rated for 30A, NEMA 10-30, or 14-30.

- Comment on How Do I Prepare My Phone for a Protest? 1 week ago:
Smartphones are far too valuable to our efforts to be left at home. They are the difference between personally observing law enforcement atrocities, and being able to prove them. The media isn’t covering the protests. We need as much video as we can get. We need to be able to coordinate efforts, passing along troop deployments and numbers.
While our main phones and accounts are probably linked to more information than law enforcement should ever be allowed to touch, burners add too much to our efforts to seriously consider not bringing them.
- Comment on How Do I Prepare My Phone for a Protest? 1 week ago:
Ideally, that burner phone never goes anywhere near your home or any place you frequent from the time it is acquired until the time it is destroyed.
Briar is a good messaging app for you and your group. It will work (to some degree or another) over bluetooth even after they shut down the cell towers. Keep posting information about law enforcement deployment numbers and locations.
Airplanes.live provides unfiltered ADS-B data, useful for identifying and locating law enforcement aircraft, including drones.
For uploading media, choose overseas fediverse instances for your account, which are not subject to US law, and won’t get shut down or raided by US law enforcement if you upload something they don’t like.
I’ve been suggesting this everywhere: pick a dozen different protest locations, and share your list with everyone you meet. If and when law enforcement deploys in force at your current location, leave for another. Force them to constantly redeploy to multiple locations.
- Comment on Franks and Beans: Take 2 1 week ago:
IMO, you can’t really cut “sweet”. You can increase the complexity; you can make it “rich”, but the sweetness tends to overpower whatever you might add.
You might have better luck starting with British-style baked beans. My local (US) grocery stores carry Heinz Beanz

- Comment on Front Brake Lights Could Drastically Diminish Road Accident Rates 2 weeks ago:
Turn signal or not, you shouldn’t be pulling out in front of them. You should be assuming they are turning into a driveway after the intersection, or that they mistook your intersection for the next one down the road, or that they left their turn signal on from a lane change 5 miles back.
Turn signals are lies until conclusively proven otherwise.

If she is still financially reliant on her parents, you should abide by her wishes on the subject. You should not consider it a reflection of her relationship with you. She is doing what she needs to do to survive and thrive.
Eventually, she might choose to rely on you for financial support. But, you could be killed in a traffic accident, and she would still be dependent on their support. Even after you are supporting her financially, she still needs to maintain her relationship with them.
You should not consider her relationship with her parents to be a reflection on your relationship until she is capable of supporting herself, independent of both you and them.

I’ve found a few references claiming that Sil-Fos brazing rods contain only silver, copper, and phosphorous. They should be fine.
- Comment on Front Brake Lights Could Drastically Diminish Road Accident Rates 2 weeks ago:
I want to equip my vehicle with an annoyingly loud external speaker so that when someone near me does something dumb, I can personally shame them.
CB radios often had a “PA” switch that sent your microphone audio to a loudspeaker under the hood.
I’d prefer a “FlameThrower” button next to the horn.
- Comment on Front Brake Lights Could Drastically Diminish Road Accident Rates 2 weeks ago:
Ah. I see. They are emitting a green light, so I know they’re braking, and it’s OK to cross.
But, it turns out that they’re planning on turning into a driveway past the intersection, and not into the intersection I am crossing.
That’s OK. I can check “impersonate a hood ornament” off my bucket list.
We already have this problem with turn signals: there are circumstances where it would be confusing and dangerous to use them in the manner prescribed by law, and to avoid dangerous ambiguity, they should actually be used much later than the law specifies.
- Comment on Front Brake Lights Could Drastically Diminish Road Accident Rates 2 weeks ago:
YOU SHOULDNT GET IN FRONT OF ANYTHING YOU ARENT SURE IS STOPPING
This, exactly. This “plan” sounds terrible to me.
No, I’m not braking to turn at the intersection you’re sitting in. I’m turning into a driveway just past that intersection. If you pull in front of the green light the government says I have to have on my vehicle, I’m going to t-bone you.

- Comment on Am I weird for avoiding flying on prop planes, and only fly on jets? 2 weeks ago:
I would expect more mishaps from a regional turboprop, flying ten 45-minute flights a day, than a widebody flying a single 12+ hour flight a day.
Mishaps are most prevalent on takeoff and landing. The aircraft that make the most takeoffs and landings are going to have the highest mishap rate.
- Comment on Am I weird for avoiding flying on prop planes, and only fly on jets? 2 weeks ago:
The risk of a mishap is greatest on takeoff and landing. Inflight mishaps are extremely rare.
A “flight” is one takeoff and one landing. The largest aircraft have the longest duration flights. They might be airborne 12+ hours at a time. They might fly fewer than 10 flights a week.
Small commercial aircraft flying local and regional routes might be shorter than an hour. These aircraft might have 70 flights a week.
A student pilot in the smallest, single-engine GA aircraft might spend all day shooting touch-and-goes to build time and experience. Each touch-and-go is a landing-and-takeoff. These aircraft might have 300 “flights” a week.
Yes, the smallest aircraft are going to have the highest per-airframe mishap rate, simply because they experience the most risky phases of flights much more frequently than large aircraft.
Per-flight, the risks aren’t significantly different.

A320 seat configuration is 3-3. ATR-72 is 2-2. I’d take a guaranteed not-middle-seat any day.

- Comment on New fuel cell could enable electric aviation 3 weeks ago:
“The math is somewhat different” does not give adequate consideration to the importance.
That 777 I mentioned? The fuel weight on a maximum range flight is more than twice its remaining payload capacity. Fuel weight is the primary consideration you need to be looking at. The efficiency gains from charging batteries (relative to electrically-produced fuel) cannot justify the losses from their constant weight.
- Comment on New fuel cell could enable electric aviation 3 weeks ago:
The typical issue with fuel cells is not energy density, it is the fact that you need to waste a lot of energy to regenerate and transport the fuel.
I’ve never understood that thinking. Yes, it takes energy to produce fuel. So what? We started with a form of energy that couldn’t be stored and transported, and converted it to a form that could be. That’s the entire point.
So, overall, you’ll need to spend much more energy (= both recurring and upfront costs) compared to running battery-powered transportation if you want to make it a close cycle similar to batteries.
That’s not actually true.
A 777 can carry up to 320,000 pounds of fuel, which gives it a 9000 mile range. It will land about 300,000 pounds lighter than it took off.
Build an electric version of the 777. Put enough batteries on board to make a 9000 mile flight, and it will weigh the same amount on landing as it did on takeoff.
Put that original 777 on the 2600 mile flight from LA to New York, and it doesn’t need a full fuel load. You can drop 200,000 pounds of fuel, and add 200,000 pounds of payload.
The e777 will still have the same weight of batteries needed for that 9000 mile flight.
Swap out the batteries with fuel cells, and you can take on an optimal, sub-maximal fuel load for your shorter flights, radically improving total efficiency over batteries.
