Awesome. I will add it to my list of places I want to visit just based on name alone. A few others include Batman, Turkey, Shitterton, England, and Saint-Louis-du-Ha! Ha!, Québec.

Yeah it’s kind of an arm’s race with people feeling they need to be the biggest thing on the road to feel safe. I’ve driven a few larger vehicles as airport rentals when they had nothing else in stock, and I’ve noticed they also tend to have a lot more blind spots than what I’m used to.

I remember when I was taking lessons, my instructor said I should think of the airbag as being a spring-loaded spike that will impale you if you screw up. I guess he was trying to impress on me that it’s not good to feel safe and smug when you’re driving? And actually, I’ve read since that air bags can be pretty violent when they go off, so he may not have been as far from the truth as I thought?

I wish there were more regulation on the size of private vehicles, particularly in North America. It’s pretty clear at this point that what is contributing to higher pedestrian/cyclist fatalities despite better urban infrastructure is the increasing curb weight and ground clearance of automobiles. We can hope that collision-avoidance tech in newer models may reduce human-error type accidents, but at the end of the day, kinetic energy is a bitch.

I wonder how the EV transition will affect things? On the one hand, an EV would weigh more than an ICE of the same class since batteries are heavy. On the other hand, batteries are also the most expensive component by far and you need more in a larger vehicle, so from a dealer’s perspective, the margins may not necessarily grow the bigger you go like with an ICE. The sweet spot might actually be something smaller. (In fact, for me, it’s actually ebikes.)

If you haven’t been there yet, OneZoom is fun to explore. I am continually surprised by what I find there going down some random branch.

But the mining, milling, and production of nuclear fuel, as well as the construction and decommissioning of nuclear plants, emit greenhouse gases at levels ranging from 10 to 130 grams of carbon dioxide per kilowatt hour of power — lower than fossil fuels but higher than wind and hydroelectricity (and roughly on par with solar).

That’s interesting. The article they link gives a bit more detail:

These energy intensities translate into greenhouse gas intensities for LWR and HWR of between 10 and 130 g CO2-e/kWhel, with an average of 65 g CO2-e/kWhel.

While these greenhouse gases are expectedly lower than those of fossil technologies (typically 600–1200 g CO2-e/kWhel), they are higher than reported figures for wind turbines and hydroelectricity (around 15–25 g CO2-e/kWhel) and in the order of, or slightly lower than, solar photovoltaic or solar thermal power (around 90 g CO2-e/kWhel).

The wide range for nuclear apparently comes from difficulties in estimating the carbon footprint of mining/processing the uranium, but that nuclear is sort of in the middle of the pack in carbon footprint relative to renewables in spite of the fueling costs is good to know.

I suppose these sort of numbers may change dramatically in years to come. Take solar. A lot of focus seems to be on the efficiency of panels, which would almost certainly lower the carbon cost per unit of energy as it improves, but a breakthrough in panel longevity would also do that in an amortized emissions sort of way.

It’s been a long time since I got my astronomy degree, but your version is what I recall also. Whatever small rotational perturbation in the initial gas becomes more pronounced as it coalesces in on itself and defines the plane of the star system. Planets form within this plane after it is defined, and they all travel in the same direction around the star.

Regarding galaxies, the most common spiral ones like our own Milky Way follow the same principle at a larger scale. But there are also elliptical galaxies, not to mention irregular ones. In an elliptical galaxy, there is a more random movement of stars in a cloud around its core. So they look more 3D I guess, to go back to what the OP was asking about. I seem to recall the most accepted explanation for how these form is from the aftermath of a collision between 2 spirals? So presumably, when our galaxy collides with Andromeda in several billion years time, the resulting combined galaxy may emerge as an elliptical?

This could be why Obiwan wound up a hermit? (Programmers of my generation at least talk about “Obiwan errors” because his name sounds like “off-by-one”.)

Sometimes people will say “That person’s name!” or “Those group of people!” in anger. “That Donald Trump! How dare he claim immigrants are eating pets?” to give you a current example.

When spoken of a family member or mutual acquaintance with a chuckle, it means more like “That person has some strange quirk but what can you do? We still love him.”

For example, you might hear “That dog! Always chasing his own tail.” So I think this is likely what you were getting from that conversation? It’s certainly not a criticism of your use of the word “people”.

I am not deaf, but this is triggering a pet peeve.

It seems a pretty common occurrence that I will be walking into a restaurant, bar, airport, doctor’s office, or whatever, and there will be a TV on a news channel with the sound muted or very low. For F’s sake, put the captioning on! What’s wrong with you?!?

Years ago I watched a documentary about Trump’s shenanigans in Atlantic City. Basically, he stiffs the contractors who build his casino. They sue, and so he hires some big shot lawyers to defend him. They get him off for the most part, but then he then turns around and stiffs the law firm itself! Like what even?!?

Something to be said for the wfh movement too.

I thought I read somewhere that when they were making one of the Toy Story movies, there was some catastrophic data loss that nearly tanked the whole production. But then one of the animators came back from maternity and said wait, I think I have most of it synced to my home server? And the next thing you know, John Lasseter himself is barrelling down the highway to her place and it turned out yeah, she did have it.

I understand the concept of riding a bus being free time to read or use the phone, but my experience for my commute has been standing room only for an hour.

Well at least that speaks to good ridership numbers where you are. I guess they need to add more buses, bus priority lanes, or other higher-capacity transit options.

I would love to be able to use an e bike to get to work, but I don’t like biking next to cars on anything more than a 30 mph road.

It’s worth investigating what possible routes you can take to get from A to B, as there are generally more options with a bike than a car but they are not necessarily obvious. For example, after having a close look at a satellite view, I realized that what I had assumed was a railway track was actually a decommissioned rail line that had been converted into a trail, and it actually cuts some distance off of the car route I had been taking to work.

Last night, I actually discovered a new route for getting home from band practice. I used to cut through a cemetery, but with the nights getting longer, it was starting to creep me out going through there in pitch black conditions, even though the bike has a headlight. (Cemeteries in the day time can be quite a pleasant ride though.) But I carefully surveyed an apartment complex that looked impassable. In fact, it had a foot path leading through it and beyond. This one was hard to spot on satellite since it runs through a tree tunnel.

The biggest problems are typically bridges, where you really have no other choice but to cross with the traffic. I am frequently advocating to city officials to improve cycling infrastructure along any such traffic choke points.

Cool! I can see how optical media could, in theory, be very long-lasting as long as you don’t use materials that oxidize or otherwise degrade over time.

Well I guess I’m picturing DNA encoding like a RAID billion in terms of redundancy, so with some checksumming, you ought be able to sort out any mutations? But I’m no geneticist.

That’s why I back up my data on stone tablets in Cunieform.

Seriously though, if you wanted data to last for centuries, what would be your best bet? Would it be some sort of 3D-printed mechanical storage? At least plastics are generally not biodegradable, though they are photodegradable, so I guess you’d want to stick your archive in a dry cave somewhere?

Or what about this idea of encoding the data in the DNA of some microbe and cutting it loose? What could possibly go wrong?

The time cost is certainly an important factor to consider. It’s interesting to me that my Gen Z kids have a markedly different perspective on transit vs driving in that regard. They say if you’re driving, that’s time lost, while if you are on the bus, you can be doing all sorts of things on your phone or what have you.

For me, a car commute works out to around 15-20 min if there is no traffic (a big if). The ebike is more like 25-30, but it is generally far more pleasant—at least in good weather—as I can cut through parks and trails. The bus is perhaps 45 min if I catch it right, but unlike the bike, it feels longer than it is.

One factor to consider is that if your work is of a sedentary nature, both transit and cycling factor in some exercise into your daily routine which I would say is not wasted time in that case. People who take transit are generally in better shape than people who drive everywhere, since there is an element of walking around, sometimes carrying stuff.

I wasn’t sure an ebike would give me any exercise, but I think it’s safe to say it does. In the video, they say free transit translates to 2x usage per individual. For me, that ratio coincidentally also describes the regular bike vs ebike experience. So while my old bike provided more intense workouts, the ebike provides more consistent (albeit lighter) exercise since it is really my primary transportation at this point with exception to the months of Jan and Feb when the car admittedly takes over again for the most part.

Public transit is not free where I live. I think there are two aspects to this matter of whether or not it should be free, or at least subsidized a little more. The video primarily addresses one of them, which is what the implications are for those with low income.

But the other aspect has to do with what it would take to get people who drive everywhere today to leave their cars at home and take transit instead for routine travel like commuting. I’ve done the math on this in terms of my personal monthly budget. In an either/or scenario of taking transit exclusively with no car ownership, there is no question that public transit is far more affordable. But once you have taken that leap and bought a car, it is no longer the slam dunk in favour of transit. What I mean by that is if you own a car but take the bus to work every day and only use the car for occasional errands that necessitate it, you will not necessarily be ahead financially at the end of the month.

At least not in my case. Some things could affect this calcuation. For example, if I had to pay for parking where I work, transit would almost certainly win. But it’s a shame when I think others are likely going through the same calculations and drawing the same conclusions, leaving ridership numbers low and streets clogged with automobiles.

What I eventually concluded was that a third option—investing in a ebike for commuting/light errands—was indeed a slam dunk budget-wise, so I have gone with that. I still need to have a car at my disposal for certain things I do, but it stays in the driveway 80% of the time, and beyond the upfront cost of purchasing the bike, its operational costs are very close to zero. So it’s basically free transportation once you’ve paid it off, and that is quite compelling to me.

You know, I’m not actually quite sure what I’m doing, but I can tell you I am not looking at the keyboard. I suppose it’s similar to how I play violin? I don’t look at where my hand is but it shifts to different positions depending on what makes the most sense for the pattern I’m trying to play, and yes, a different position does imply a different fingering to reach the same notes.

When learning to program, I initially tried to follow the touch typing guidelines, but they say that you should use the right pinky to reach every key towards the upper right end of the keyboard, which gets old fast given how frequently you need to access them. And just as with music, there are patterns. In programming, you may frequently need to type {}, :=, or even something like \{\}, and flailing around with the pinky is a good way to give yourself carpal tunnel. So your right hand learns to shift to hit those keys using a combination of fingers.

As a Gen X, I think my typing speed peaked around late high school/early university? I tried to teach myself touch typing and got moderately proficient. Then I got into programming where you need to reach all of those punctuation marks. So my right hand has drifted further to the right over the years, which is better for code but suboptimal for regular text.

One thing that’s really tanked for me though is writing in cursive. I used to be able to take notes in class as fast as the prof could speak. Now I can scarcely sign my own name.
