Feels like building proteins, or some kind of RNA/DNA molecules.

I think these people are either bots or paid shills. No other sane explanation for thinking gloried chatbots are better than the space race. It’s not in good faith. Mods do nothing and get mad if you spend too much energy pointing it out.

I give at least this poster the benefit of the doubt that they're describing something akin to HAL from 2001: A Space Odyssey (which we clearly don't yet have). But I suspect they think we're on the cusp of that breakthrough and it will overshadow Apollo in the long term.

Love these deep dives—perfect HN fodder. Add to that articles like this also on the front page today: "Algorithmically Finding the Longest Line of Sight on Earth," "Tesselation Kit"…

HN, keep being HN! We love you.

A hobbyist analog computer I will open-source.

I have been through a number of iterations of adders, integrators… It's starting to coalesce now into a finished PCB. (Iterating is slow though at the PCB stage since we're round-tripping via Asian PCB fabs.)

As often happens, I want to learn about something (analog computing in this case) and I find that a deep dive where a kit comes out at the end is an enjoyable way to explore (I also get more experience with KiCad and, for this project, SMT).

The seed of this were a few articles on building a "lunar lander" circuit in early '70's electronic hobbyist magazines I found online. Pre-home-computer, how does one create a lunar landing simulation? Why with op-amps and panel meters of course.

And so that is where I began. But I'm way past that now though by making instead a general purpose analog computer.

I watched some of the videos and you could see DNA paternity tests sitting around on the tables in front of the dancing girls his Manhattan townhouse ( example- 24 seconds in - https://www.justice.gov/epstein/files/DataSet%2010/EFTA01648...) .

Interestingly if you change the last couple of digits in the video links to just any random number combo it unlocks a ton more (many awful, disgusting) videos. Changing the file names from .mp4 to .mov also opens up more, and changing file names in the links from .pdf to .mp4

The most interesting thing I've found is the word "don't" is often randomly redacted in emails which makes me think they ran a script to auto-redact "Don T" among other things. Example: https://www.justice.gov/epstein/files/DataSet%2011/EFTA02440...

Edit- also, to add, the craziest part of the entire files to me was how much awful stuff I could find just merely poking around. If you put in the name of any of his multiple girlfriends/victim recruiters - for example natalie malyshev you can find them sending him photos of underage girls with him replying ranking them - too old, too asian (many were rejected for being too asian), too fat. There is one being evaluated who is only 10!

Are you suggesting there are accessible files at justice.gov for which the URLs were not part of the "dump"? That simply swizzling the URL you can access additional files that were not part of the released tranche?

I have always failed to understand the obsessive dream of many engineers to become managers. It seems not to have to do merely with an increase in revenue.

Is it really to escape from "getting bogged down in the specifics" and being able to "focus on the higher-level, abstract work", to quote OP's words? I thought naively that engineering always has been about dealing with the specifics and the joy of problem solving. My guess is that the drive is toward power. Which is rather natural, if you think about it.

Science and the academic world

Once you've written enough image caches, I think you often find yourself ready to move on to the higher level architecture of a larger project.

Often too it's the architecture that can cause a grand idea to crash and burn—experienced devs should be moving toward solving those problems.

To be clear I’m not negging the moon landing. I just think it may only Be humanity’s second greatest achievement

But thinking machines, even if they only have an IQ of 70 right now, even if they may end humanity, are still a technological marvel on the order of splitting the atom

JKCalhoun · a day ago
I see your point then.

Somehow this doesn't feel like the same kind of achievement though. We had the whole of the country pulling for the moon landing. Instead we have a handful of CEO's schmoozing Wall Street, raping the power grid, making hardware unobtainium for the rest of us for this "moon shot".

We chose to go to the moon because it was hard. We choose to build AI because it will make corporate America rich? (Somehow doesn't have the same ring to it in Peoria.)

And as we have already seen, the downsides of AI are extensive—they may turn out to outweigh the benefits? Other than cost, it's hard to find a downside to the moon landing.

We can (and should) provide for those among us who aren't able to provide for themselves, without also firing everyone in the welfare department. UBI is shit. People need to do something in order to recieve money, even if the something is begging on the side of the freeway or going into the welfare office to claim benefits. Magic money from the sky is not the answer.
JKCalhoun · a day ago
I agree with you about magic money. Frequently downvoted when I put it forward but by and large I think that the human psyche needs to have a daily sense of having "accomplished something".

Otherwise I suspect many of us will (reluctantly) drift off into lives that center around drinking alcohol, playing video games…
