In consumer space, 69 KB of RAM (138 x 4 kbit chips) would cost around $1700 70s dollars for the entire package, ~$10k in modern dollars. Radioationed hardened for space though — $50k-$100k in 70s dollars, roughly the price of a Silicon Valley house back then - $300k-$600k in today's money.

Wouldn't they just put a lead plate around the computer? That can't cost 100k in 70s

Because lead turns a single high-energy particle (that would disturb a single bit and punch through) into a shower of many low-energy particles (that would disturb many bits AND induce lattice damage over a wide area).

Space is mostly empty there is not much interesting stuff to collect and who’s going to buy that data LinkedIn on the other hand has user behavior, computer details etc. that’s a lot of interesting data.

>Space is mostly empty Yes, but Space is big. Really big. You just won't believe how vastly, hugely, mind-bogglingly big it is. I mean, you may think it's a long way down the road to the chemist's, but that's just peanuts to space.

Exactly and people on LinkedIn think they are smarter than everyone and definitely smarter than dolphins, because what dolphins do? They muck in the water all day having good time whereas humans built important profiles on LinkedIn having good time berating each other.

I don't understand who uses that network anymore. Everytime I login it's all ai generated stories next to ai generated flavor images of people sounding like a parody of themselves ("what taking my kids to school taught me about business scaling"). Out of all places to doomscroll, why choose the one that feels like an episode of Severance?

It's legitimately useful for networking, and also for keeping track of professional events. On the other side of the equation, it's also useful for sales teams using LI Sales Navigator as a lead enrichment platform. This doesn't excuse any of the numerous dark patterns in the app, or the memory consumption.

Some links?

The juxtaposition between this and "Voyager 1 runs on 69 KB of memory and an 8-track tape recorder" is probably the best one I've seen in a long time

We now have simple chat apps capable of doing almost anything LinkedIn does while using under 100 MB of RAM.

I remember when your computer had 128MB of ram and could still run an entire desktop OS, web browser and chat app at the same time.

Don't know if this is satire, but I do wonder if Musk uses the Grok app himself.

As someone who knows xAI employees, he does use it a LOT and reports bugs very often afaik

The "very often" part is wild to me. You'd think being an engineer himself[0] he'd fix the root cause: the testing process, not work as an IC QA himself.

[0] He holds the title of Chief Engineer at SpaceX.

Lead makes things worse, not better. High-energy particles go straight through a couple mm of lead no problem, and lead itself is radioactive anyways. The problem is when a particle punches straight through a chip, leaving some energetic charge behind. You won't stop that with a paper-thin layer of lead. Also, lead is extremely dense.

"and lead itself is radioactive anyways" Um, I guess in that there are naturally occurring isotopes of lead that are unstable. But those are very rare and can be removed. By this standard, the chips themselves are radioactive since they are made of silicon. By this standard, you, everything you eat, every plant and animal is radioactive since there are trace isotopes of carbon that are radioactive (that's how carbon…

No, the real reason it isn't used is because coating your chips in something doesn't really work

well that's any framework with vdom, the GC of web frameworks, so I'd imagine it's also a problem with vue etc.. I don't understand though why performance (I.e. using it properly) is not a consideration with these companies that are valued above $100 billion like, do these poor pitiful big tech companies only have the resources to do so when they hit the 2 trillion mark or something?

Nobody gets promoted for improving web app performance.

Yes, they do. OGs remember that Facebook circa 2012 had navigation take like 5-10 seconds.

Ben Horowitz recalled asking Zuck what his engineer onboarding process was when the latter complained to him about how it took them very long to make changes to code. He basically didn't have any.

it's unironically just react lmao, virtually every popular react app has an insane number of accidental rerenders triggered by virtually everything, causing it to lag a lot

Is it time for vanilla.js to shine again with Element.setHTML()?

https://developer.mozilla.org/en-US/docs/Web/API/Element/set...

It's a bit unfortunate that several calls to .setHTML() can't be batched so that several .setHTML() calls get executed together to minimize page redraws.
