Everyone you know is stupider than you imagine.

odr_k4tana,

@ct_bergstrom too stupid to imagine here, sry.

I was recently at an interdisciplinary meeting (heavily skewed toward, but not exclusively, social science academics) in which easily 85% of the people there said they were working on AI or something related.

The current AI/LLM/AGI/whatever mania seems to have metastasized even more broadly than blockchain did. There are interesting and important problems there, but it seems to have become an intellectual black hole across the academy.

odr_k4tana,

@mattblaze one rule: academia will research the things that get them grants. It's sadly the way it is. See covid research etc. The reason they're doing it is because it keeps the system alive and gives them money.

odr_k4tana,

@jjdavis @mattblaze there's a lot of social science garbage around COVID. Just search the archives.

So much chatter lately. Don’t worry they’ll be payback in season 😂

odr_k4tana,

@Fury I hate both seasons.

odr_k4tana,

@Fury don't really have one, I think. Or at least I'd have to think about it.

MFA is OK BUT couldn't they make it so that the cursor is active in the field into which one is supposed to enter the verification string?

odr_k4tana,

@dstephenlindsay oh yeah, that's a particular pet peeve of mine as well. Or the more malicious version: not recognizing numpad-enter after input.

Our atomic fountain is now - for the first time - able to launch atoms! Great to see all the progress happening on the apparatus I spent the last years setting up :ablobcatattentionreverse:

Do yourself a favour and don't use the {likert} package in . It apparently isn't maintained anymore, uses close to EOL functions (even whe it still was maintained) and its documentation + usability is crappy as heck.

odr_k4tana,

@coolbutuseless I mean. Sure. If one has the time.

odr_k4tana,

@coolbutuseless I've seen the code. I believe it needs complete refactoring.

odr_k4tana,

@jbryer I respect that, but maybe then include a short notice on github that it isn't maintained anymore or something of the likes. Whatever you do with your package is of course your personal business. Nonetheless, I stand by what I said, for the reasons I mentioned.
(And for the record: "functions as I intended" doesn't mean anything when my post clearly is about usability.)

odr_k4tana,

@smach @jbryer my intention was to advise others to not use it (see OP). Anything other post was a mere reply to others.
I will not offer feedback to software that clearly isn't maintained anymore since 2 years. Call me pessimistic, but to me that's a sign that this project was given up.

poll meme:

Each of the big paradigms in R (base, tidyverse, data.table) represents a room (as shown below).

Which one do you choose to run R code? (poll in next post)

odr_k4tana,

@TimTeaFan the one that I feel like using.

If your exam or test uses questions with true/false or yes/no answer options, deducting points for wrong answers while not deducting points for no answers will NOT reduce guessing.

Math:
reward for guessing right: +1
punishment for guessing wrong: -1

mean: 0.
Chance for getting one point: still 50%.
This only works for highly risk-averse persons.
I would guess every time.

odr_k4tana,

@owoid right, on average. But that average only plays out in large numbers for the same question. For singular guesses this does not apply. You still have a 50% chance to get one point. That is SO MUCH (even though most people would intuitively disagree).

What you instead should do is use multiple answer options and punish at the same rate. This shifts the equilibrium away from high guessing rewards to high honesty rewards while also not punishing people who just misremember.
Dichotomous answers are just no good if you're truly testing (!) something.

odr_k4tana,

@owoid actually there's multiple ways to do this. What many do is to state that 0 to X (x being all) answer options can be true, and the point for each question is only awarded if you have selected all correct answers (if no options are correct, then zero selection will award 1 point). This is actually quite strict but tests with high severity.

odr_k4tana,

@owoid I don't think so. The point is that if somebody truly misremembers or learnt something wrong, they are punished as if they guessed. If you cannot distinguish this, then designing a punishing function for guessing is just nonsensical.

odr_k4tana,

@codehorse reasonable!

My grandparents were born at the end of WW2. During their lifetime:

  • Car ownership became mainstream
  • Air travel became mainstream
  • Same sex marriage was recognised by many countries
  • (Germany's) laws changed so that women did not need their husband's permission to work
  • Mental health was recognised as a "thing"
  • Communist states worldwide vanished by 90-something percent.
  • a nuclear arsenal capable of destroying this planet a few times over was built
  • DNA was discovered
  • Medicine was revolutionised through antibodies, computational modeling and gene therapy.
  • Computers became a household item
  • Humanity developed space travel and turned it into a service
  • We built a globalised trade network capable of delivering goods within weeks across the world.
  • The internet was invented.
  • We built scyscrapers almost 1km tall
  • We developed machine learning models that can mimic human reaction and (sort of) pass Turing tests.
  • Smart Phones were introduced
    etc.

The past century spawned 90% of everything we take for granted nowadays. Considering the time mankind existed, this is nothing. Next time you think somebody is annoying because they can't deal with change ("it's 2024, come on"): that's normal. We cheated evolution so hard that we're outgrowing our own capabilities to adapt. Toilet paper in its modern form has only existed since the 1920s. Calm down.

Es ist so irre: in DEM Land, das wie kein anderes an Bargeld festhält und das wie kein zweites Industrieland in der Digitalisierung hinterher hinkt, wird speziell für Flüchtlinge und Asylbewerber ein extra Bezahlkartensystem eingeführt. Das ist zudem auch noch Ländersache und wird wohl deshalb nicht einheitlich sein.

Da sieht man, was der Grund für die schlechte Digitalisierung ist: es ist gewollt.

odr_k4tana,

@marquito nuja. Gibt genügend Länder, die noch weiter hinten sind. Japan ist da z.B. so ein Fall. Das mit den Vergleichen ist immer schwierig.

Finally booked all my accomodation for the upcoming Japan trip :)
Yay!

Cooking up another batch of salsa. This time, more on the tomato side and using 4 varieties of chili (arbol, passila, habanero, chipotle) for flavour and spice. Cooking chicken with it to give it some extra roundness. Let's see how that works out!

wenn das so weiter geht, hat meine Forschungsarbeit 1 mehr Seiten als mein prof glücklich ist zu lesen :(

odr_k4tana,

@blue1337blood wir Korrigierenden sind empfindlich was sowas angeht. Kürzen, kürzen, kürzen.

odr_k4tana,

@blue1337blood Anhang plus Quellen zählen normalerweise nicht. Zumindest nicht bei mir. Aber das musst du deine*n Prof fragen.
