You have the right attitude and I hope you are able to successfully shop around. Some institutions are paying below living wages to overworked and precariously employed instructors. Of course they phone it in. Those places are not worth your money and just trying to cash in on the “diploma” ==“job ticket” mentality.
Find a place that actually gives a shit about education and you should find professors interested in actual education that will see your attitude as refreshing.

40 years of telling kids a degree is a job ticket rather than explaining the value of a liberal arts education.
Every time I see k12 education discussion focused on “preparing kids for the job market” I cringe. Its the cart before the horse and just as agile.

A paper notebook is basically the same fundamental as a password manager but with a different tradeoff. You trade cryptographic security for a reliance on physical security. Its probably a great option for a lot of older people who only log into things from home. But its just a password manager. An analogue one.
Flashcards are dumb for this. If you are going to write it down, just secure it. Don’t have them out all the time to try to memorise it. Jese. The worst of both.

I can’t tell if you are self deluded or really are an interesting case. I do question using a screensaver to help memorise a password rather than a password manager.
- Comment on LastPass notifies users of yet another data breach 1 week ago:
Plenty of research on the topic. Humans cannot remember a unique, high bit random password for each service. Using your brain means one of the following. Low bit passwords that can be cracked, memorable passwords that can be guessed via social engineering, and/or password reuse where one breached service breaches many accounts.
The only known solutions are all based on some sort of actually random generation of passwords, combined with storage of some sort for all but a very small number of extremely important examples (typically just your password manager vaults password). I actually think a paper notebook and dice or card system is an under appreciated option for a lot of people, which falls under the above.
There is one weird alternative, and that is deterministically generated high bit passwords (via a cryptographic hash function). Unfortunately it doesn’t work well with stupid snowflake sites that have their own “good password” rules, and falls completely flat when you have to change passwords for just a single or few sites for whatever reason.

Currently, there’s no entrenchment, as the apps are open source and there are self-hostable servers. You can easily get your data out and even continue using the apps indefinitely (the whole database stays locally in the app, offline; you just loose sync unless you self host a server).
I say that because that is the minimum bar for any alternative. I use them and am not panicking yet, but if I was starting from scratch, I would be cautious about choosing them.

VC funding is the enemy. I’m beginning to think it matters as much as the libre/proprietary software distinction.

I usually treat them by using an extremely well established library where someone else has spent the requisite years crying over every stupid edge case of csv reading. Rolling your own csv reader is a bit like encryption. Until someone hands you a file that rejects all sanity and you start fking with regex. Lol.
- Comment on Just the way we likes it. 2 months ago:
The delimiter isn’t really the issue. Its that there are lots and lots of weird edge cases that break reading csvs. If you use commas, at minimum, you need to escape commas in the data, or quote strings that might contain commas… But now you have to deal with the possibility of a quote character or your escape character in the data.
Then you have the fact that csvs can be written with so many different character encodings, mangling special characters where they occur.
Aaand then you have all the issues that come with lack of metadata - good formats will at least tell you the type of data in each column so you dont have to guess them.
Lets see, its also really annoying to include any binary data in a csv, theres no redundancy or parity checks to catch currupted data, and they arent compressed so you need to tack on compression if you want efficient storage, but that means you always have to read the whole csv file for any task.
Oh, that brings me to the joys of modern columnar formats where you can read selected columns super fast without reading the whole file.
Oh god, I really kept going there. Sorry. Its been a year.

It was some sort of weird database frontend the contractor used. It was very limited.
- Comment on Just the way we likes it. 2 months ago:
P.s. in the above quagmire, the only solution is choose to keep only the most important un-clean column per csv, and make it the last column in the file so you have predictable columns. If you need more, then write separate csvs. Computers are stupid.

God I hate csv with the fire of a thousand suns.
Contractors never seem to know how to write them correctly. Last year, one even provided “csv”s that were just Oracle error messages. lol. Another told me their system could not quote string columns nor escape commas or use anything but commas as their separator, so there were unpredictable numbers of commas in the rows when the actual data contained commas. Total nightmare. And so much of my data has special character issues because somewhere in the pipeline a text encoding was wrong and there is exactly one mangled character in 5 million lines for me to find.
Give me the data as closely to the source data as you can. If it is a database, then a database dump or access to a clone of your database is the best option by far. I don’t care how obscure your shit is, Ill do the conversion myself.
For intermediate data, something like parquet or language specific formats like Rdata or pickle files. Maaaaybe very carefully created csv files for archival purposes, but even then, I think parquet is safe for the long haul nowadays.

People expanded to places with resources that they could live in, or bring back home. There are no resources that we know of in space that are not more easily accessed on Earth, and living out there would require a material investment from Earth that would be devastating.
Most of the Earth is currently empty of humans, while space is colder than Antarctica, and less accessible than both the top of Everest and the bottom of the Mariana trench. You could build a city in any of those 3 places easier than even low-earth-orbit and any other celestial body would be thousands of times harder still.

There’s no job from those times you couldn’t do today while literally living better than they did. Quit your job, give away everything you own and go live in a tent in the woods harvesting mushrooms: Your life would still be better than theirs because you would still have access to some emergency healthcare, foodbanks when you are starving, and be protected from marauding pillagers.
- Comment on Just in time 8 months ago:
Even being a king of that time would be a brutal life in a lot of ways. Death all around and a piss-poor chance of surviving any given year with every bit of your body intact and functional, extremely limited dietary variety, and the smell. Oh god the smell.

Yeah, camping and campfires are nice. They are nice because they are temporary and by choice.

Yeah, this is very much glorifying the past, and probably the future. Medieval peasants would dream of sitting in a warm cubicle, well fed, while scrolling lemmy, if they could imagine it. Space colonization is probably impossible too.
- Comment on Why aren't Linux based mobile OSes more popular? 8 months ago:
A lot of technical answers, but consider a social driver: Linux users and developers are a lot more likely to prefer to do their computing on a “real” computer with a keyboard and large screen. Therefore, Linux as a desktop/laptop OS will always be significantly ahead of mobile offerings.

That’s why this is so terrifying. Twitter at least had a politically engaged userbase, so people noticed the changes. Tiktok users get political content only incidentally, and has far fewer actual journalists. They are going to get manipulated beyond reason.

That, and most traditional dairy consuming European cultures never actually drank milk. They made cheese and butter, then poured the remainder in the pig trough to turn those calories into pork.

It’s pretty open. Step 1 is make income tax as painful as possible, step 2 is get rid of it in favour of tarrifs and other regressive revenue generating fees. And MAGA was already convinced that progressive taxation helped people they want hurt.
