This is not an example of nor even an attempt at long horizon thinking. Voyager wasn't built with the intention that it would last for decades. It was a rush job to take advantage of a very rare planetary alignment and it's primary mission was completed 12 years after it started.

It is a testament to the ingenuity of the engineers who have worked and are still working on the project that they've managed to keep it to some degree functioning for so much longer than it was intended to last.

I loved watching "It's quieter in the twilight", a documentary about how a dedicated team of engineers (mostly retired) are fighting to keep the Voyager mission alive.

> The screen, which has been dubbed retinal e-paper, has a resolution beyond 25,000 pixels per inch. "This breakthrough paves the way for the creation of virtual worlds that are visually indistinguishable from reality," says a Chalmers news release about the breakthrough.

neilfrndes commented on How America got hooked on ultraprocessed foods   nytimes.com/interactive/2... · Posted by u/mykowebhn

This all has very big "uncured bacon" energy to me (if you didn't already know: there's no such thing; vendors of uncured bacon performatively drive the same chemical nitrite reaction using vegetable extracts). For example: yogurt becomes a UPF simply by dint of adding carrageenan, which is on the order of calling dashi a UPF because of the kombu.

It's not that there isn't a very legitimate issue underneath all this: packaged, hyperpalatable, low-nutritional-density low-satiety foods are probably a major driver of health problems. It's just that "UPF" isn't the right metric for isolating those foods, and with the wrong metrics you end up in a similar place as California does with the Prop 65 warnings.

We went through a similar thing with "pink slime" (transglutaminase preservation techniques).

The book Ultra-Processed People by Chris van Tulleken really opened my eyes about UPF. I highly recommend it. Here is a video of him delivering a lecture at the royal institution about the topic: https://m.youtube.com/watch?v=j1oOoYnCfJs

I don't think adding kombu to dashi would count as UPF according to the book's definition.

What is the advantage over Duckdb with Spatial Extension.
neilfrndes · 3 months ago
While DuckDB is excellent, I've found the spatial extension still has some rough edges compared to more mature solutions like PostGIS.

1. The latitude/longitude ordering for points differs from PostGIS and most standard geospatial libraries, which creates friction due to muscle memory.

2. Anecdotal: spatial joins haven't matched PostGIS performance for similar operations, though this may vary by use case and data size.

3. The spatial extension has a backlog of long-standing GitHub issues.

I am going to derail the conversation from the pen and into the refills.

As a left-handed that refuses to twist their hand to avoid smudging everything: what refills brands offer the best dry time to avoid black or blue smudges?

neilfrndes · 5 months ago
I found iroshizuku inks faster drying than the other brands I've tried. Paper matters a lot too, I've experimented with many and finally settled on Rhodia.
