Growing up in a small town, I could see thousands of stars on a clear night. In a major metropolitan area where I live now, it’s hundreds. When I visited Beijing for three weeks, I think there was one night where the pollution cleared sufficiently to see any stars at all; I think I saw three or four.
The rocket in question is a nuclear thermal rocket, not a nuclear electric rocket. The 10GW figure refers to waste heat.

The reason for pulsing the engine, and the advantage over a normal nuclear thermal rocket is that the heat generated by operating at full power continuously would be unmanageable.

What difference should it make whether it’s a computer with a built-in touch screen or a computer with a mouse, keyboard, and whatnot? How is one “optimized” for this or that? They’re both just computers. The one running Apple’s software is utterly locked down, is the thing. I would like to be able to compute however I like on my computers, yes.

Heck, maybe it would be interesting to work on touchscreen software on a touchscreen computer in a touch oriented IDE or editor, no?
No, even if you emit less, you are still 'accumulating', but at a slower rate. And previously released methane is still converting to co2 in the atmosphere, for decades to come.

Save the file and upload Gorilla-edit.jpeg to Content Credentials. Poof! The authoritative cryptographic signature says it was created two months earlier. C2PA says there is no indication of tampering.

wtf? It looks like either the date itself isn't signed, or that the validation service doesn't bother validating the date is signed? Later on it says

>This isn't a code problem, this is a standards definition issue.

But it's not clear why the timestamp can't be validated. The timestamping infrastructure used for Windows authenticode signatures seem to work fine. Why can't the C2PA get their timestamping scheme to work?
They probably want to kill the reverse chronological grid because many tools to delete Google Photos in bulk rely on it. Photos is a great source of storage consumption (“let us auto back up every photo you’ve ever taken…”), and when it’s consumed you no longer receive email in gmail. Your only option out of this hostage situation is to delete things from storage or pay Google a subscription. Conveniently, it is painful to delete things en masse from Photos, so they hope this will frustrate you into a subscription.

Same here. My first job out of college was at a database company. Queries at the client side of the client-server based database were slow. It was thought the database server was slow as hardware back then was pretty pathetic. I traced it down to the network driver and found out the default setting of TCP_NODELAY was off. I looked like a hero when turning on that option and the db benchmarks jumped up.
Nobody is arguing with you about skateboarding destroying some property. 100% seems like hyperbole given that many (nay, most these days) skateboarding takes place at municipal or private parks.

I agree. If it's intended to be a web-based system, why not have it running as a webserver on your local machine?

Also, the intention is to have a GUI, or rather 4 or 5 seeparate GUIs:

But if you're having a web UI, why have a GUI as well? It is just extra work, and it is quite likely that the UI for these tools won't be the same, potentially making them harder to learn.

Fundamentally I just disagree with you I think; I'm not seeing any signs that trends in fertility are turning around, and I think if anything it was social pressure that was holding the numbers up to begin with. I'm certainly willing to admit that I could be wrong on that though; the millennials, a large echo generation from the boomers (myself among them) are hitting the age where it becomes a sort of "now or never" proposition and anecdotally, I do see some people considering it. But I also think that religion is one of the big drivers of social pressure for fertility, especially in the US, and you can see it continue to collapse which I think is a sign of the way things are going.

2B humans out of 8B are in China. You do not have numbers for China nor, if you manage to get it, can those be trusted anyway.

Having more than 640Kb of RAM isn't a good in of itself, it's only good in that applications arose which required more RAM.

Similarly higher population isn't a good in of itself. It seems to me that there's much less evidence that there's something that needs higher population.

I don't see how higher population necessarily makes humanity as a collective organism more human. That seems like saying that an individual human is more human if they weigh more.

A friend recently discovered a very strange plant growing in their garden. It seemed utterly alien. They used an online visual tool to identify it. It turns out it's something called "horsetail" and it's considered a "living fossil". (In its later stages of life it does look much more plant-like).

Via wiki:

> Equisetum is the only living genus in Equisetaceae, a family of vascular plants that reproduce by spores rather than seeds.

> Equisetum is a "living fossil", the only living genus of the entire subclass Equisetidae, which for over 100 million years was much more diverse and dominated the understorey of late Paleozoic forests. Some equisetids were large trees reaching to 30 m (98 ft) tall.

https://en.wikipedia.org/wiki/Equisetum

The plants that we see right now are just a snapshot of what's currently successful. If we eventually find alien life somewhere, the strangeness might look a lot like the earth-bound "aliens" of our own past.

> Actually, I think the standard of living, at least in the long-term and for the many future climate refugees, is not actually that much improved.

Compared to what? Where do you draw the line of the "pre" technology? Technology has been as part of human society since before we invented history.

Do you have a specific point after which you think technology became a net negative? Do you think thinks were fine pre-industrial revolution, but after we invented the steam engine things when to shit? Perhaps it was the domestication of bananas that really took us away from living in harmony with nature rather than twisting it to our own ends.

I don't think it really makes a sense to draw a line in history and say everything after this point is bad. The only sensible way to draw a rational technophobic line is to look at specific technologies and their effects and decide if your life will be better or worse with each.
> could allow for crewed missions to Mars to be completed within 2 months. As it stands today with commonly used propulsion systems, a trip to Mars takes around 9 months.

Both numbers are pulled out of thin air. The Hohmann transfer time between 2 planets is about half a year. Which year, you ask? The year of the inner planet, or of the outer planet. Well, it's the average of the 2 years. A Martian year is about 2 of our years, so the average is 1.5 years, divided by 2 it's 9 months.

But if you are willing to burn more fuel, you can cut down the travel time. The delta-v between Earth orbit and Mars is surprisingly low. From the Moon transfer orbit to the low Mars orbit it is 2.5 km/s. The rule of thumb is that a rocket can achieve twice the delta-v of its exhaust velocity. In the case of the SpaceX Starship, the exhaust velocity is 3.7 km/s, twice that is 7.4 km/s, about 3 times the delta-v needed for the Hohmann transfer. SpaceX states they will be able to get to Mars in 6 months [1]. Musk went further and claimed that the Starship could get to Mars in as little as 80 days, and this fantastic Stack Exchange post [2] explains that maybe 80 days is slightly too optimistic, but 90 days is doable.

Now this design here claims that the rocket can achieve an ISP of 5000 seconds, which means an exhaust velocity of 50 km/s. With such an exhaust velocity, basically they can pick any random number and claim they can get to Mars that fast. The shortest path between the two orbits, the radial one, is about 75 million km long. At 50 km/s, it takes 1.5 million seconds, or 17 days. Of course, this is for a one-way trip, but presumably in the far future we could preposition fuel in Mars orbit for the return trip.

Maybe they thought half a month will sound too wild, so they went for the 2 month number to make it sound more realistic. The problem is that compared to the 3 months doable by SpaceX, it's not all that impressive.

> HN is a pretty toxic place indeed

This may be a personal style difference, but I find HN to be the least toxic of all social media I’ve tried. LinkedIn would be my example of ultra toxicity – the aggressive positivity there is unbearable. At least on HN people tell you what they think and even use a constructive decently argumented approach to doing so.

HN to me feels like a good technical discussion where people tear apart ideas instead of each other.

But yeah if you put a lot of ego into your ideas, HN must be an awful place to visit.
I agree in general, but there will always be certain requirements and team structures where stuff like this makes sense.

For me, I work in a small team of 6 devs on an ever growing app and feature set. I 100% will leverage managed services where cost and complexity allow. SQS is one of the most stable and cheapest AWS service, and the ability to just use it and not have to sysops it means we can spend more time building features.

Could you expand on what you see as exciting developments? I’ll have to check out the op post link as well as yours and others in the thread.

It’s been a few years since I seriously looked at options for my personal use, but I remember being quite disappointed in the options I found. Zotero and org-noter seemed two of the best (though in completely different ways) pieces of software I could find regarding reading or organizing pdfs. I trialed OneNote for a year and liked it in the moment, but zero support for navigation or discovery or review of information make it untenable for building a knowledge base or doing literature review.

I imagine that software which makes reading and connecting document information (in any form: pdf, html, video or other) could be so much better than what I use daily.
I imagine it's like AI code generation: the work required to review the merge is very likely more then the work required to implement the merge.

Yes.

MVC as in Model-View-Controller.

Humanity will eventually go extinct, but birth rates would need to decline much further or stay this for a very long time before it’s a meaningful issue.

Further, people alive in 2300 will be decedents of people who chose to have kids generation after generation despite living in an industrialized environment. That self selection both in terms of DNA and culture means a population bounce back becomes increasingly likely over time especially as fewer people means less pollution and less competition for resources.

Humanity might even end up cycling through industrialization, collapse, hunter gatherers, agriculture, industrialization, multiple times before settling on some stable equilibrium. You just can’t extrapolate exponential curves indefinitely when they depend on the population size.
I'm definitely the opposite, however I definitely use version control differently and less rigidly in personal projects. I commit more, care less about making the "perfect" commit, and making one change per commit. It's a lot more freeform in my personal projects precisely so it doesn't get in the way and take the fun out of the project.

What if we changed the kernel or tcp stack to hold on to the packet for only a short time before sending it out. This could allow you to balance the latency against the network cost of many small packets. The tcp stack could even do it dynamically if needed.
this is an interesting question. i have asked myself looking looking back at my life if there are any choices that i could have made differently if nothing else changed and i didn't know then what i know now. and my conclusion is that no, i would not have changed anything. wanting to believe that i could have made a different choice is wishful thinking likely influenced by regret about bad choices.

there was no decision that was entirely random yet strongly influencing the future.

however, here is an idea for a possible proof that free will exists: the freedom to believe in god or not. there is nothing in the world or in ones life that can determine that belief. sure, certain experiences can influence that belief, but nothing can determine it. we always have the freedom to either believe or not believe in god. and we can change our mind any time. on the other hand, the choice whether to believe in god or not is able to influence every other choice we make.
