So true. NASA's achievements are the highest of human accomplishments, imo. Sometimes I picture being on the team that built these triumphs, I think I would be overtaken with pride forever.

There's a nice 2017 documentary about Voyager called The Farthest [1]. It includes interviews with many of the now very old team members, and they do exude (deserved) pride, and a still fresh sense of wonder that they pulled it off. [1] https://en.wikipedia.org/wiki/The_Farthest

FANTASTIC documentary! Beautifully made, engaging, entertaining for those well familiar and very accessible to the layperson. I caught it by accident, right at the beginning, while flipping through public-access TV and spent the next hour+ positively glued in front of the TV. Didn't even move to the couch - just transfixed in front of the TV where I was standing when I caught it. Later bought it on BluRay.

I don’t know how well it holds today but for some time it was known that running certain computations on existing hardware would take longer than waiting for new hardware and running when available.

My life archive is available to my heirs and successors as long as they know the LUKS password for any of the numerous storage devices I leave behind. It’s risky though — the passwords aren’t known to them yet and one logistical slip up means the disk may be unusable. That is, however, until some point in the future when they will have a computer powerful enough to just break the key and feast upon my cat photos, tax…

RE 50TB/year, or $100 of storage How is this storage amount obtained for that price ?

Wow, perhaps I’m an exception to the norm, but this isn’t my experience at all. My family regularly sends interesting historical records of the lives of our ancestors. My great aunt composed a historical record of my great grandfather, who over his life built dozens of houses by his own hand. Even at university, I read a number of interesting historical letters and documents of the people who lived in the same dormit…

The key difference may be in the volume. Old pictures are more important to a family because there are so few of them. I only have one picture of my grandfather because it was taken when cameras were rarer than hen's teeth and 35mm film hadn't been invented yet. Now we have hundreds of thousands of pictures between the family members. Every vacation, every meal, every unimportant moment in time. I don't have time to…

Leave everything and let LLMs curate it on demand. "Show me pictures of my grandpa during the 2020 pandemic." "Show me pictures of my grandma's hobbies." "Find the most interesting pictures in this folder, not interesting historically but interesting action or visuals." "Make a montage of my cousins growing up." "Change my wallpaper every day to the most interesting family photo from that day of the year."

Definitely a threat at the nation-state actor level, the NSA are already providing guidance on how to use encryption today that is resistant to future advances in computation that would data recorded today to be decrypted later.

I don't see where you're getting this from? It's so blatant that things are only improving, the US is running so many high profile missions, SpaceX alone has launched almost 100 times this year, Starship testing is proceeding well, we're reasonably on track for a long term human presence on the Moon, we're gradually preparing for Mars, China is managing to maintain its own space station, India is closing in on its ow…

What I'm getting this from? Reading the news for the last 40 years or so. Watching the new generation and their education levels. Seeing how science is now 'the enemy' rather than the future. > SpaceX alone has launched almost 100 times this year, Starship testing is proceeding well, we're reasonably on track for a long term human presence on the Moon, we're gradually preparing for Mars, China is managing to maintain…

> I'm not one of the believers in Elon Musk, his Mars Colony is just a way to get people to do what he wants them to do.

I'm sceptical Musk will actually succeed in establishing a genuine "Mars Colony" in his lifetime.

However, I think it is very likely SpaceX will succeed in landing an uncrewed Starship on Mars-likely within the next 10 years. Even if that's all they achieve, that would represent a massive increase in our robotic exploration abilities, simply in terms of the significantly greater mass - we could land dozens of Mars rovers in a single mission.

And I think a crewed Mars mission eventually happening is likely too. It is likely to take a lot longer than Musk thinks, but he's only 52; he probably will still be around in another 30 years, and it is not impossible he'll still be around in another 40, so I think the odds he'll live to see a crewed mission to Mars are decent.

But there is a big gap between "small-scale crewed scientific research station" and "interplanetary colonisation", and I'm sceptical Musk will live to see that gap traversed. Although he'll probably handwave away the distinction, and claim the first as the start of the second.

I don't think the south American Brazilians are anywhere near as prudish as the central north American USofA denizens.

I think ‘readily accessible’ was the important bit.

I don't follow. The wallet is the private key, along with some other info.

The wallet could be encrypted with a strong password and thus inaccessible.

No, indeed, I'm not a believer. When I see someone that lies with abandon and who regularly behaves in absolutely horrible ways towards others and that person happens to want to establish a colony on another planet my first thought is 'nutcase' not 'savior of humanity'. I marked Musk very early (long before his name became a household item) as someone with a ton of potential and he has definitely realized some of it.…

What of spacex’s performance are you extrapolating from?

This is the era I'm referring to, and I recall the difference being a bit beyond marginal. Literally the verification (i.e. read) phase of the burning sequence would take several times longer... in practice, not in terms of advertised maximums. Maybe it would read data discs at 48x but it would refuse to read audio discs beyond 8x or something like that. Same goes for ripping software like Exact Audio Copy (EAC); it…

You and the GP are misremembering (also the abundant misinformation sticking around the web is of no help). CD-R are mostly obsolete but some of us still have working equipment and do continue to burn CD-R, so that era hasn't completely ended. No idea exactly what you're referring to taking several times longer, perhaps software was misconfigured. However what is more likely: The market was flooded with terrible qual…

> Red Book CD audio ripping is an entirely different subject

> difficulty of directly streaming Red Book Audio

Actually, it's what I was alluding to this whole time. Sorry for not saying so out of the gate. Red Book audio was my life for a while. I recall writing cue sheets [0] for CDRWIN by hand! Ripping groups would brag that a given release was created with EAC at no more than 2.4x or something like that...

I believe data CDs (whichever color book that was) had more robust error correction (given that computer files can't just have glitches interpolated like audio can to some extent) which is why if you completely filled a CD with Red Book audio (74/80 minutes), ripped it to an uncompressed format like WAV/AIFF, and tried to put all of it on a data format CD as files, it wouldn't fit; it was a decent amount larger than 640/700MB and not just due to metadata.
