Still in use in many places for some ungodly reason.

At my previous job they had been using Notes since the company was founded in the early 90’s, meaning they lived through it being Lotus Notes, then IBM Notes and now HCL Notes.

Everything was deeply entrenched - email, warehouse inventory, ERP system, all documentation made in the entire company… just everything.

And this is for a scandinavian company manufacturing high tech devices for telecom and aviation, among other things.

It was… an interesting nightmare, constantly got in the way of any sort of productivity. Definitely contributed to me leaving early

And hidden https://news.ycombinator.com/hidden

(I literally just accidentally pressed hide on a post and was wondering how to un-hide it when I saw this post, nice coincidence!)

You can email HN to enable a hidden feature that hides the hide button/link. I've got it enabled because I never used the function anyway; it's much nicer not being able to accidentally hide things. Not sure why it's not on the profile page

Yeah, I immediately thought of Kikuchi lines from electron diffraction in crystals https://en.wikipedia.org/wiki/Kikuchi_lines_(physics)

Very cool!

There are also techniques for the TEM (transmission electron microscope) to visualize and measure magnetic fields such as electron holography.

Esentially by splitting the electron beam in two, passing half through vacuum and half through a magnetic sample, then recombining the beams, you can extract magnetic information from the interference pattern of the two beams with some Fourier analysis magic.

I have a writeup with examples from a project i did years ago on my blog, if anyone is interested: https://longcreek.me/blog/2021/holography-intro

A project management tool/kanban board app. Similar to Trello, except Linear is way nicer to work with in my opinion.

It's extremely opinionated though - and sneaky because it looks like Trello (cards-in-lanes), but it really isn't; it took a lot of frustration to realize it's more like one of the older tools where the "canban board" is just a duct-taped-after-the-fact view over their underlying data model.

In Trello I can set up lanes and move cards around as I please, in Linear strange things suddenly happen, and it's super confusing to tell what is possible and what isn't.

Like, what lanes a card can be in depends on which team owns the card; try to move a card from one team into another teams lanes, it won't let you without first "migrating" the card to be owned by the other team.

Scientists also tend to study what they can get funding for, which is often easier for more beautiful or easily explainable subjects.

It's an interesting take, but wouldn't it be more favourable for the humans to simply dry the meat and save it, e.g. for summer where there are enough other food sources to mix it and avoid the protein overconsumption?

Cold, dry areas are ideal for drying meats, like they do with Norwegian stockfish https://en.wikipedia.org/wiki/Stockfish

If you watch Werner Herzog's "Happy People" documentary about trappers in the Siberian Taiga, and see the relationship between dog and man there, it's easy to see how this relationship could have played out. A bit of frozen fish or meat for the dog, but not too much, means protection and assistance on the trap line, and a companion through the winter.

EDIT: My border collie currently lying behind me on a bed is anxiously and steadily watching me because what she really wants me to do is put on my skis and go for a hike in the woods with her. She won't really be happy until I do that.

Herzog's documentary is just a new cut of the original Russian documentary, adding Herzog's old hippie narrative.

The original version is fantastic, and much more authentic. Available on YouTube, with subtitles, on the director's own channel:

If a dog is useful it may be a better use of the excess protein, especially for nomadic peoples. The dog will carry around all of that extra meat and provide a service. Drying/storing the meat may also attract predators.

Depends, you want to get fucked up by bears?

Did they known how to dry meat though?

Yes, foraging groups in dry climates are quite sophisticated at short-term meat preservation. I know the Hadza for instance regularly dry meat on nearby tree branches or cook it over a fire.

To me it seems like there has been a much larger issue of photographs, movies etc. being digitalised at some point years ago using some standard of the time, after which the originals were discarded because "there, now it's saved and the old ones are an inferior media anyway".

Then you're left 20 years later with a horribly jpeg'd mess in 800x600 px.

I don't have a source on this, but it's my impression a lot of libraries did this in the 90's or 2000's (if someone knows specific cases i'd love to hear about them, I hope I'm wrong)
