I find as I get older and my vision is not what it once was, I need bigger screens with good contrast but don’t care so much about resolution. I think it was on the show Corner Gas where they were talking about how big a screen you should get and concluded the size in inches should match your age. That made me laugh but I have to confess now there may be some truth in that…

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?

Geez don’t give him any ideas!

Thanks! I hadn’t heard about that one. Here another article on it. Wow.

Articles like this really float my boat! It reminds me a bit of the discovery of the Wollemi Pine in Australia.

Thought for a moment there the dude on the right was Emperor Palpatine?

Our mayor has been a mixed bag. He has been fairly progressive in terms of improving public infrastructure, but has had a poor track record on social issues.

Currently, he is courting a scandal involving a violent altercation at a safe injection site where someone got bludgeoned to death. His response was a rather draconian closing of the facility (he claims it’s only temporary) and essentially telling the homeless in the area to get lost. As you might imagine, this is not going well.

I have no interest in running for any political office, though if I did, the city council would likely be highest on my list. I actually enjoy watching them in session from time to time on the local cable channel, as there is less partisan bickering at the municipal level and, as you say, the decisions they make are more likely to affect your day-to-day life.

I am sort of half-heartedly angling to get on a committee involving the city’s cycling infrastructure, but that’s about the extent of any political ambitions.

It varies wildly depending on where you go. I think the worst-case scenario in terms of car-built cities would be someplace like Phoenix, Arizona. Visiting that city, I gained an appreciation for what it must be like to have a physical handicap that affects your mobility, because being in Phoenix without a car is comparable to having a disability. You cannot go anywhere on your own two feet in any reasonable length of time. It’s the kind of place where you need to find a Walmart to buy a loaf of bread. The closest thing to a corner store is going to be a gas station.

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?!?

They’re going to keep making more powerful hardware either way, since parallel processing capability supports graphics and AI just fine.

It’s not quite as simple as that. AI needs less precision than regular graphics, so chips developed with AI in mind do not necessarily translate into higher performance for other things.

In science/engineering, people want more—not less—precision. So we look for GPUs with capable 64-bit processing, while AI is driving the industry in the other direction, from 32 down to 16.

Right now, it is southwestern-style Indian upma with eggs and salsa. My wife invented that after randomly picking up a package of instant upma from a nearby Indian grocery and noting that it reminded her a bit of grits. We are afraid to tell anyone of south Asian background of this no doubt sacrilegious interpretation.

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?!?

I posted this because it gave me a hint as to why conservative propaganda has shifted in recent years. It’s mostly personal attacks on the man at the top now. “F#ck Trudeau” and all that.

While this might make some sense in the US where the presidency is an institution unto itself, it makes a lot less sense in Canada where we have a parliamentary system in which running the country is a group effort by the dominant political party.

And Trudeau is not even a power-trippy type of leader. He’s always been more of a delegator. So while I believe there is plenty of reason to be critical of the current federal government, pinning it all on the prime minister just seems weird and off. Like something a foreign influence campaign would be trying to do, in other words.

Something to be said for the wfh movement too.

I suppose the regolith itself could be used as a heat sink. I don’t know what its thermal properties are like?

But yeah, I imagine heat dissipation is a limiting factor. Everything I’ve read suggests the 1st gen reactors will put out something on the order of 10s of kilowatts, so rather modest by nuclear standards but still plenty for a nascent Moon base I imagine?

The trouble with solar on the moon is that the day-night cycle is a month long. You have to figure out what to do during the 2 Earth weeks worth of night.

I suppose with a polar base, you could have several solar farms strategically placed so that at least one of them is operational at any given time, but that’s a lot of infrastructure and this is early days.

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.
