As a time traveler I expect to have knowledge of what readers exists. verbatim makes archival grade DVD, blu-ray, and CD media guaranteed to last 100 years. Put copies on a couple different time capsules and I’m good. However I don’t have much confidence that media readers for any of this will exist. Even if I put a reader in the time capsule I’m not confident it will survive - the media will be good but the mechanics probably are lost to corrosion, so this is the most important part.

Does it really need to be all 100tb? Can I find a small subset that matters? We have history of payrus scrolls with the correct ink that have a proven history of lasting thousands of years when left in a desert garbage dump. You can find the recipe for making both the scrolls and the ink in the bible. Copy by hand, leave in the desert, in a location I know archeologists will dig in 100 years. This is very limited amounts of data that can be saved though.

If the above doesn’t work, non-acid paper when laser printed (not inkjet!) should last plenty long. Again I don’t think I can get anywhere near your 100tb, but I remain convinced everything we need can be archived on it.

That means you haven’t make them large enough yet.

Good luck getting people to care, but it is in the end your best counter.

Long term boycottes are the best thing - IF you can get large numbers to follow. Large enough that management schools are forced to teach about how ever real reform won’t be enough to save you from bad actions.

That is for individuals. Whichever side you are on. No alternative can exist without both creators and users in large enough numbers.

Asking which is first is a stupid question. Even if you could prove an answer it wouldn’t change a thing.

I’m sorry I can’t think of how to write that nicer.

I’ll admit to not being very good about homework, but I didn’t wait until the last minute when I did do it. I was an okay student at best. Doing more homework would have helped me more than anything else.

That question is likely illegal to ask. Only ask questions relevant to your job. Culture fit is will your form a book club together, it is can you work with this person and then go home. If you are regularly doing such social activities with everyone you work with outside of work hours you need to get a life. (it is okay to make friends with people you work with, but that isn’t a goal.)

Learn the material not study for the exam. That means do the homework. That means attend the lectures. That means read the textbooks. Preferably do all of the above on different days. The key is to see the same material (in different contexts) many times before the exam. The day before the example you do a quick review and that is enough.

The limits of our knowledge of biology. There is no particular reason I shouldn’t be able to regrow you from the skin cell you left on the doorknob - the DNA is all there - but nobody has any clue how you would go about doing that. (if we ever get there it will make for some interesting nature vs nurture data). Only time will tell how much we figure out in the future. For today the limits are where they are.

ZFS even if only one server is much better than most people have. If your ZFS replication is to a different building you have done pretty good. However as others have pointed out there are limits. Those servers costs you a couple bucks/month in electric (where I live my electric is 100% wind, but most of you should read CO2). You have to buy both servers, and hard drives will crash regularly.

There are a lot of trade offs, but cold storage backups are often much cheaper in the long run than the backup zfs server. And those cold backups are a lot easier to put into multiple different locations.

It is a pain to figure out how to give everyone the same user id. I only have a couple computers at home. I’ve never figured out how to make LDAP work (including laptops which might not have network access when I’m on the road). Worse some systems start with userid 1000, some 1001. NFS is a real mess - but I use it because I haven’t found anything better for unix.
