I thought about CMYK too! If I'm bored enough I might vibe code one.

"CMYKdle" would be a pretty awful name but it'd be straight to the point ๐Ÿคฃ

I also switched to Medium difficulty since the double arrows were making it too easy for me to pinpoint the final answers. Now I'm failing some after 6 guesses so that's definitely in my zone of proximal development ๐Ÿ˜

It's pretty tough! I'm usually able to figure primary pair colour combinations (e.g. Red + Blue = Purple, etc.) as a starter, and then learning the rest. Latest was realising Brown colours is mostly R and little bit of G and B.

Hello Bluesky friends, I wrote a book about OnlyFans that is coming out SOON.

Would you use this book as a set reading in your course/unit/subject? Would you like an inspection copy? Let me know! I'm thinking media studies (especially social media/internet studies), sociology, gender studies etc

Today's Good Thing: I finally found a slightly run down grumpy-looking mom & pop Asian restaurant with all Asian customers that served a very delicious and flavourful cold dry noodles dish ๐Ÿ˜‹ Hit me right in the nostalgia ๐Ÿ˜

Shamelessly adding Hexcodle to my daily 'dles so I can actually sit down and better my understanding of RGB colours and how they mix to form the others.

I'm thinking I need a way to notify myself of upcoming public holidays because I didn't realise there was one today as well. Hmmm...

(Previous workplace usually had reminder emails from the department secretary, which I appreciated!)

Iโ€™m not thrilled with the title. Is this what happens when they run out of binders full of women? They get shoved in microwaves?

Finally decided to sit down and read the instructions on my ginger beer brewing kit that I bought 6 months ago.

Recipe calls for lemon juice, which I'd put on my shopping list yesterday but didn't think I'd need to get /facepalm

Last night I (mostly vibe-) coded (using free Claude) a basic times tables quiz to help a student I'm privately tutoring/mentoring. Whole thing took less than an hour collectively, design was all Claude's doing. Very interesting experience.

One fundamental rule of UX in general is to minimise these small stops and frustrations that can very easily turn people off (which can happens a lot in maths). And tidyverse smoothes over that very well.

Personally I think the ease of usage of tidyverse (especially given the number of multiple mini frustrations with base R one could have) outweighs any kind of..."wanting to keep it natural", especially for a new-to-programming and programming-averse crowd.

05.03.2026 09:03 ๐Ÿ‘ 1 ๐Ÿ” 0 ๐Ÿ’ฌ 1 ๐Ÿ“Œ 0

Only con I can think of is that the way tidyverse does some things is not really seen in other programming languages, but this assumes people will transition into other programming languages later, which isn't always a given.

I remember being so confused the first time I saw people do that on TV, like "Why were they so intensely looking at their watch?" ๐Ÿ˜‚

Today's Derp Moment:

"I'm looking at a bunch of clinical data on <condition correlated with weight> and all the patient's weights are over 150kg" ๐Ÿ˜ฌ

"Oh whoops, I was reading their heights" /facepalm

I'm thinking about a stats report I presented yesterday and find it amusing that I basically knew /what/ to do and say, but I didn't have the right structure to display most of it as much as possible. Thankfully one of my supervisors fixed that before presentation, eep!

I love that you start with addressing all the potential questions/arguments people might have against it.

All your arguments make sense and is consistent with my current thinking. Only major blocker is the amount of admin work, really!

Even though I do hearing accommidations for myself most times in a way without bothering other people (usually when there isn't an opportunity to advocate) there'll occasionally be a very curious individual.

Was at a graduate student seminar this morning, left my microphone on the lectern to hear the speakers. After things were wrapping up, the organiser noticed the mic and started talking into it assuming it was a room mic, not realising she was talking straight into my ear ๐Ÿ˜‘

Oooh I occasionally make them and their variants - there's a lot one can do with just glutinous rice flour and water ๐Ÿ˜

TIL "to be square" (i.e. "Be there or be square") is American slang starting in the 1940s, referring to someone who is conventional and old-fashioned. No wonder I'd never heard of the meaning beyond the saying.

Thankfully had the common sense to flip through the rest of the text/chapter to check for consistencies just in case, then got my hands on the style guide much later (whew!)

Teaching myself about outlier detection in multivariate data. First page of Google search pretty much only tells me about Mahalanobis distance. Free ChatGPT gave me a bunch of other techniques (which I'll verify!) and I'm wondering where else I could've found a similar list... ๐Ÿค”

I'd say a silver lining at least is that they've been around for so long for most people to be aware of these problems, therefore we can try other strategies to mitigate them and/or make them more accessible.

Mewgenics moment: Fighting Dybbuk and he possesses my cat that had a Sniper Rifle, meaning the next two turns, two of my remaining three cats got K.O'd immediately :(

I didn't even get a chance to use it on the boss himself :(

The sexual assault case was great, too. I'm most likely never ever going to be in that kind of scenario so I really appreciated seeing what the experience looks like and how difficult it is for all involved parties.
