denimnerd42··on Rolls-Royce calls off bets on electric planes, says low-carbon fuel is future
Sounds more feasible than electric planes though. That never made viable sense to me. At least they could build a 737 sized alternative fuel plane today.
denimnerd42··on Rolls-Royce calls off bets on electric planes, says low-carbon fuel is future
oh gotcha. To me it's all in the same. Some engineered alternative that produces less carbon. it's terribly semantic though because every fuel today is engineered to produce less emissions.
denimnerd42··on Rolls-Royce calls off bets on electric planes, says low-carbon fuel is future
There's no mention of biofuel in the article. But yes any technology designed to reduce the impact of the fuel production/use cycle. In F1 it's branded as synthetic fuel right? It's like a natural gas derived fuel but could be derived from anything the scientists engineers can make work. Jet fuel is heavier so starting with an oil derived from bio matter might make more sense. Either way something designed with less impact than drilling for fuel.
denimnerd42··on Rolls-Royce calls off bets on electric planes, says low-carbon fuel is future
They are developing these fuels for Formula1 and the like. Probably won't see them in road vehicles due to cost. But never know. It's likely normal fuels in hybrids or pure electric vehicles will be better (cheaper and lower carbon). For trains overhead electrification would be better.

I'm not sure the fuel itself is that low carbon but the cycle of producing it may be. I'm sure a quick search would reveal they produce slightly less CO2 or something in a suitable engine.

denimnerd42··on Please don't use AI to get on the global leaderboard
always thought that was a bad argument even back when we weren't all running around with cell phones in like 4th grade. I think learning math without aids is crucial but there are better arguments than "you won't have technology at X"
denimnerd42··on Ask HN: What was the outcome of Reddit blackout?
I don’t know. I think the writing has gotten bad. I like thrillers and dramas. The old good stuff Ive already watched at this point. It’s nice when I run across something good I havent seen. The new stuff I can just predict what’s going to happen in a way I wish they’d just get to the point. Maybe I dont know whats going to happen but all the dead end loops are just excruciating. I watch some pretty boring sports like F1, motogo, and baseball so even though they go slow and require patience at least there’s some storyline thats not predictable. With tiktok they get to their hook or point within a minute or three so even if I know it’s something stupid I know the point is coming soon or I can just fast forward next. Mine is also curated towards my hobbies so it gives me ideas about what to do next or how I can improve.
denimnerd42··on Ask HN: What was the outcome of Reddit blackout?
tiktok made tv shows and movies unwatchable for me haha. that kind of media is just too slow. only sports at this point. I would say I watch 45m/day of tiktok. 5m here and there.

glad to work remotely somewhere we only ever use phones.

denimnerd42··on Is Delaware the cheapest place to incorporate?
Its cheaper because when you hire lawyers they are more familiar and things have already been sorted out mostly. If you're not dealing with lots of $$$ then you don't need Delaware.
denimnerd42··on Sam Bankman-Fried doesn't recall
that happens all the time
denimnerd42··on GM, Honda scrap plans to co-develop 'affordable' sub-$30k EVs
yeah but it's not even close to available yet. they've got 6 or 7 cars ahead of it to produce. the equinox, blazer, silverado, a cadillac, the acura/honda, others?

I'm guessing the Honda was supposed to be based on the equinox and as the Honda that is coming was based on the blazer. the promised 30k equinox will probably never show (at that price) so Honda said lets cancel it.

denimnerd42··on GM, Honda scrap plans to co-develop 'affordable' sub-$30k EVs
that's what I bought, but it's canceled because it doesn't use their current battery technology called "Ultium." Unfortunately they went all in on big expensive EVs with their first Ultium vehicles so I don't think they will sell that well as hybrid or gas would be my choice for those larger cars.
denimnerd42··on Amazon reaches 10k Rivian electric delivery vans in US
sounds more fair to drivers if everyone is policed equally. otherwise like you say, they are forced to speed. if you want to drive safely you can't and also keep your job. whereas now the metrics will show what is reasonable.
denimnerd42··on Amazon reaches 10k Rivian electric delivery vans in US
ugh don't even get me started on landscaping crews. I want to start a business to displace all of these guys on my surrounding streets using solely electric equipment. I'll even run it at a loss just for my sanity. My neighbors are importing this crap to my neighborhood and some of them realize it and others are oblivious I guess. Here in my area they blow all year around even if there's no need for it.
denimnerd42··on Amazon reaches 10k Rivian electric delivery vans in US
Yeah but seeing these delivery trucks and ride share based delivery cars accelerating as fast as possible and stopping as fast as possible over and over again in your neighborhood where your kids play outside is not so great.
denimnerd42··on Bank of America's unrealized losses on securities rose to $131.6B
They will suffer in the profits department due to this. If they're making 1% when they could be making 5% on 450 billion or whatever the total original balance of HTM was then their stock will be rightfully crushed. (actually has already been rightfully crushed)
denimnerd42··on Amazon reaches 10k Rivian electric delivery vans in US
I love seeing theses things in my neighborhood. Delivery trucks make the most noise after garbage trucks and assholes with modified exhausts. (edit I left off landscaping crews because that insanity just makes me angry so I guess I disappear it from my mind when at all possible)

The drivers tell me they hate them because they report every speed limit violation to their bosses. Sounds great to me!

denimnerd42··on Investigating a teen’s death on an ebike and the Rad brand’s safety
Does it say "no motorized vehicles"? That does not include ebikes in my area (Southern US).

What I'm talking about is what I saw when I traveled to China. They have these sections of the main streets that are just for 1 person electric vehicles/bicycles. Then they have the main road on one side and the pedestrian sidewalk on the other. That's more what I'm talking about.

denimnerd42··on Investigating a teen’s death on an ebike and the Rad brand’s safety
Yup. A bike can go 60+ down a hill.
denimnerd42··on Investigating a teen’s death on an ebike and the Rad brand’s safety
I do remember national and local news segments about kids dying or being disabled by cars while they were riding their bikes. Most of the time there had to be some kind of point to drive home so it was about lack of helmets or whatever. Not that they really help vs a car. But that's why I just lied about where I was going. I never would have been allowed to ride across the major roads where I was going. If I had died they would have victim blamed me too.
denimnerd42··on Investigating a teen’s death on an ebike and the Rad brand’s safety
These stories are going to come out more and more.

I'm all for getting kids out and letting them be independent. I would ride my bike to the store across all sorts of roads when I was 12-13 year olds to buy rated R movies and Parental Advisory CDs. ("Mom, I'm going for a bike ride!")

When you add these 20-25mph+ ebikes (they can be easily fooled to go faster than legal) and no prefrontal cortex development the situation can get scary quick. Unfortunately we don't have the infrastructure or dedicated, separated bike lanes that make them safe. so stupid solutions like "banning them" are obvious and lazy but there's not much else to do immediately.

denimnerd42··on IRS consultant charged with disclosing tax return info to news organizations
It's just regressive in general. normal people, especially today, have half or more of their net worth tied up in their home. so all of us normal people are effectively being wealth taxed while the very richest are effectively not being.

My wealth tax in texas is ~2% :( I've got say for example 100k house with 50k equity and 50k cash and stock assets. I pay 2k in property taxes on 100k in property but 2k/(50k+50k)=2%. not real #s but real percent.

denimnerd42··on IRS consultant charged with disclosing tax return info to news organizations
that would make sense right? old money isn't going to take more income than required to make purchases, otherwise you pay taxes. if you include wealth gains and not just income, they will be more heavily diversified so their gains will be much smaller but hopefully more consistent.

this true tax rate shenanigans drives me nuts though. so dishonest. yeah my true tax rate is like 5% too.. my house appreciated so much last few years...

denimnerd42··on Very high number of workplace accidents at Tesla factory in Germany
it's for diecasting. just gooogle dosing furnace diecasting

"Dosing furnaces are closed holding furnaces with a spout for direct metal delivery. They are used to dispense an accurate amount of molten metal into the die casting machine. The advantage of dosing furnaces is that because it is closed, it minimizes heat loss and protects the molten metal from excessive oxidation."

denimnerd42··on My Unhealthy Relationship with Keyboards
$500 is nothing for a tool that protects your hands and upper body. carpal tunnel, thoracic outlet syndrome, other kinds of RSI are no joke.
denimnerd42··on The elderly are becoming homeless at a rate not seen since the Great Depression
I think people mean a more irrational feeling of safety, rather than hard statistics. They don't want to see or be near those antisocial behaviors when they're taking transportation. Old people seem to suffer from this irrational feeling more than younger.
denimnerd42··on Alameda lost tens of millions because of a fat fingering mistake
I made 17.5k doing this by dumb luck.

I was trading crypto back in 2016-2017. Making a few thousand here and there. Mostly just from time in the market during the run-up of ethereum. The whole thing drove me crazy because I thought it was so stupid, like gambling. So in 2017 I withdrew my several thousand dollars and put in a trade on coinbase pro for 5 etherum at $100. (I had left $500 to do this, the most I was willing to risk at the time) On 2018-11-25 this trade was executed in a flash crash.

I had totally forgotten about this trade and when I was going to buy a house in 2021 I was looking for any change in the seat cushions thinking I may have left a small amount in these accounts. Well imagine my shock when the amount was just short of $18,000.
