Thanks! Good ones. I was thinking about programming functions, but regex hadn't occurred to me. Math formulas didn't either but I can't think of any that I would use enough to justify memorizing them.. What are some that you would include?
Yeah, seconding scientific and engineering knowledge:
- Math formulas (Integration patterns, Fourier transforms, trigonometric identities, infinite series, etc.).
- Physics formulas.
- Chemistry (Periodic table, organic compounds, formulas...)
- Astronomical Information (Bodies from the Solar System, constellation names and its main stars...)
Also, technical and/or domain specific vocabulary (I'm thinking more of L1 than L2, but both are interesting):
- Car / computer / airplanes / boat parts...
- Sports (Rugby positions, track and field vocabulary...)
- Film making / Theater
Literature & arts:
- main universal or national writers / philosophers / artists, their most important works, dates, etc.
Symbols, signs, icons, gestures:
- International traffic signs
- Sign language
Thanks faneca. Lots of good ideas there. Funny you mention boat parts...I recently started taking sailing classes and memorized a few hundred sailing related jargon.
I just thought of a good one. I can identify only maybe 4-5 different tree species in my neighborhood. I'd really like to put names to the other common ones. Ditto for birds.
If you don't already know them, then all the non-internet IP address spaces (loopback networks, private networks) as well as the addresses of some public nameservers and timeservers. Turns out, it's hard to check these things on the internet when you're having network configuration problems....
Also the names and .... erm, 'latitudes' of the constellations. (There's a word for north-south angle that isn't latitude, but i forgot... maybe that should be an SRS thing too.) East-west is harder, but the astrology constellations in order should help there. (there's a astronomical name for them too, which I've also forgotten. Hmmm.) Turns out, that checking these things on your smartphone destroys your nightvision and puts a serious crimp in your stargazing time.
The seasonal meteor showers might be good to learn too, as they don't always make the news unless other news is really slow.
I wouldn't discount learning the names of current world leaders as 'temporary' information. They won't still be the current world leaders forver, it's true, but they will remain historically significant figures for our lifetimes, and longer if they have particularly dramatic careers.

I can definitely see the use of a deck like that and probably should do one for myself. It's amazing (and sad) how bad I am with stuff other people consider "common knowledge". I remember in school I always liked learning about history but... I'd forget it so fast! I've considered buying or borrowing a bunch of modern school books and putting them into srs, maybe that could be an idea for you as well? Or well maybe not the standard school books but more condensed review books or so.
I've made anki decks outside of language learning. Often with school related things (biology, math, chemistry, art history) and non academic things such as things I need to remember from my food/beverage related jobs (allergens, policies, ingredients, plate specials).
I've also used anki to help memorize a short speech for class presentations.
td; lr: I'm a nerd.
As a historian, I think of names/dates/memorizable items very much like vocabulary words in a language. If you have ever tried to read a few paragraphs of a scholarly book on a historical field you're not familiar with (or even a good popular book), chances are you have had the experience of feeling like your head is spinning after a few sentences, because you have no idea who any of the people/places are, and it's like reading a novel with 80% comprehension - really frustrating.
A historian doesn't have to keep every detail in their head like a computer, but the greater your familiarity with the material and the greater the precision of your memory, the more clearly you will be able to focus on the analytical thinking part that really matters.
(Just for fun, here's a lecture announcement that crossed my email this week:
This lecture will examine Iranian relations with the Deccan, beginning from the time of the later Bahmanid dynasty, and then extending into the time of the Sultanates of Ahmadnagar, Bijapur and Golkonda. A particular focus will be on the presence of Iranian migrants in the Deccan, some of whom belonged to elite groups such as Sayyids, but who also included far more humble military specialists from Larestan, who used migration as a means to social mobility. A central figure whose career is examined will be that of As'ad Khan Lari in Bijapur (d. 1543), who also features in contemporary Portuguese sources.
Of all the proper nouns in that paragraph, I could identify "Iranian" and "Portugese.")

Since we're starting to throw in field specific advice, I'll add mine.
Memorizing formulae for physics (and thus engineering) without understanding the concepts first is an absolute waste of time, so I'd highly recommend against it. The formulae come directly from the understanding (usually through experimentation), so they're a pain to remember without knowing what they mean. Let's take an electrostatics example: why does the closed surface integral of electric flux density equal a charge? Because that formula says that if you know the total amount of electric field passing through a closed surface, you know the (net) amount of charge contained within that surface; any flux from outside the surface will create opposing positive and negative flux on the surface, leaving the only net flux to be caused by the charge contained within.
Understanding that is far easier than memorizing Q=Ss(D・dS) (imagine that the italic capital S is a closed integral sign; the little s is for surface)
Furthermore, you would want to understand that D and E are related directly by permittivity in most materials, so the D vector in that equation can be replaced by εE.
Even furthermore, understanding this allows you to easily grasp that the divergence of D is equal to the volume charge density (because you're essentially making an infinitesimal closed surface and saying how much the field changes across that surface, and thus how much charge is contained in that infinitesimal surface).
That's three equations (and more) all from one concept, and this is hardly a rare occurrence with physics formulae (I just opened the equation sheet we were given for an e.mag test and picked one to make this example), since there are multiple ways to express the same phenomena depending on the conditions, what you want to know, and what you already know that make it easier to calculate one way or the other.
Commonly used constants, their symbols, and names are good bits to memorize though (students starting on electromagnetism must take care to remember which constant is permeability and which is permittivity, for instance, and what those constants represent). It's a pain to look up the speed of light and the permittivity and permeability of free-space every time you need to use them, for instance, so stuff like that is worth SRSing. Just not the formulae.
Great example - of course as a non-scientist I lost the thread at "closed surface integral," but I think it all comes back to the fundamental principle of "Don't memorize what you have not first understood." It's the same reason why memorizing words from a wordlist is so inefficient unless you are regularly encountering examples of the same set of words in your reading.
