<< As casual users disengage and polarized partisans remain vocal, the online public sphere grows smaller, sharper, and more ideologically extreme.

It.. feels accurate. I don't frequent FB or other mainstream social spots, but even on HN, the pattern is relatively clear. Vocal minorities tend to drive the conversations to their respective corners, while the middle quietly moves to, at most, watch at a safe distance.

Part of me is happy about it. The sooner we get out of the social media landscape, the better the society as a whole will be.. in my opinion anyway. Still, we have already lost so much of the original internet. That loss makes me sad.

I feel like this misses what's actually going on. The "small, sharp, ideologically extreme" discussions aren't going away, they're just happening elsewhere. From the abstract, the reason for the decline is: "the youngest and oldest Americans increasingly abstaining from social media". The young people are talking in private Discord groups, and the old people are talking in private text groups. These private groups don't show up in social media studies. The paper even states this directly: "everyday communication increasingly migrates from large, open networks to semi-private spaces such as group chats and messaging apps".

Good "code" may be going away, but good architecture isn't. There's still tremendous value in learning good software engineering practices. Extreme Programming, Agile, Design Patterns, Antipatterns, TDD, SOLID, DRY, and all of the classics by Martin, Fowler, Beck, Freeman/Pryce, Brooks, Evans, McConnell, Thomas/Hunt. People who let an agent determine their architecture are in for a world of hurt.

This is interesting, because I've been going the other way: Using coding agents to write MORE abstraction layers. This is because I realized that, just like humans, in fact even more so, language models struggle to keep the whole stack in mind at once. See for yourself: Try having your agent write a CRUD app in Ruby or Python (no Rails, no Django), and then try it again with Rails or Django. It'll be a lot more productive and error-free the second time.

However, I think I understand where the author's coming from based on this line:

> I’ve been building a product from the ground up. Not the “I spun up a Next.js template” kind of ground up

Next.JS is the pinnacle of JavaScript-on-the-backend frameworks, and it's kind of pathetic compared to what Rails or Django give you. You still have a lot of thinking to do, so I posit (as I have for some time) that using Next.JS vs using NodeJS directly gives humans very little productivity boost. I think people just know that frameworks are a good thing in general, and never realized that the JavaScript offerings weren't that powerful.

That github repo is just a mirror, and if you checked the official website you'd see:

Yet housing costs keep increasing. The working class is being squeezed between employers who are suffering lost revenue and can't pay US wages, and landlords and mega-corp shareholders who won't budge on price. I foresee a slow protracted "collapse" (or really renegotiation) that will bankrupt stuck-in-the-mud billionaires (like Elon) as their means of recourse - law enforcement and the military - come under such powerful social coercion that no amount of money will stop them from siding with working-class-friendly new leadership like Mamdani, as the workers (who, despite what Elon tells himself in his robot fantasies, are still needed en masse), use their REAL voting power - moving their home to jurisdictions that are working-class-friendly.

Very cool, but I can't help but wonder how this translates to similarly complex projects where innate knowledge about the domain hasn't been embedded in the LLM via training data. There's a wealth of open source compiler code and related research papers that have been fed to the LLM. It seems like that would advantage the LLM significantly.

Not just open-source compilers, but books on compiler design, which have proliferated because every CS professor wants to take a crack at the problem.

The scammer isn't trying to get the earnest money, they are trying to get the full sale price.
phendrenad2 · 5 days ago
Is there a single case of the scammer getting a single dollar from one of these scams? My suspicion is that there isn't. (Everyone who doesn't know the answer and isn't curious should downvote me.)

> Compensations could be paid tax-exempt

I think this is the real killer feature here. Software companies could save money by simply open-sourcing parts of their software.

I think you may be overestimating how quickly this happens and underestimating how much surface area that rock has. Given no atmosphere, the fact that the rock with 1/4 the radius of Earth has a temperature differential of only 300C between the hot side and the cold side, there's not a lot of radiation happening.

In deep space (no incident power) you need roughly 2000 sq meters of surface area per megawatt if you want to keep it at 40C. That would mean your 100 MW deep space datacenter (a small datacenter by AI standards) needs 200000 sq meters of surface area to dissipate your heat. That is a flat panel that has a side length of 300 meters (you radiate on both sides).

Unfortunately, you also need to get that power from the sun, and that will take a square with a 500 meter side length. That solar panel is only about 30% efficient, so it needs a heatsink for the 70% of incident power that becomes heat. That heatsink is another radiator. It turns out, we need to radiate a total of ~350 MW of heat to compute with 100 MW, giving a total heatsink side length of a bit under 600 meters.

All in, separate from the computers and assuming no losses from there, you need a 500x500 meter solar panel and a 600x600 meter radiator just for power and heat management on a relatively small compute cluster.

This sounds small compared to things built on Earth, but it's huge compared to anything that has been sent to space before. The ISS is about 100 meters across and about 30 meters wide for comparison.

What is this figure based on?
