Happy Caturday from the towel cupboard which required extensive investigation for some reason.

Proof of cat! She is very pleased with herself and purring but she kept wanting back scritches and could not figure out why I was not scratching in the right place. She fit but strangely my hand just didn’t. Funny that.

Little sketch using Asvine V126 medium nib vacuum fill fountain pen w/ Organic Studios Nitrogen ink. Love the ink. Gorgeous sheen! Can only really see some of it on the top left mushroom cap. I am a little torn on the pen. A bit heavy and a bit slippery. Nice flow though. Filling it is weird

Very proud of myself at the moment. I have figured out how to use Affinity Photo to update the images I made for the first edition of my book. Fixing some minor errors and adding color mostly but making some new stuff too. Learning curve hasn't been too bad, which is a huge relief.

Is anyone else absolutely loathing the Nike Olympics commercial? Yes, yes you are a bad person. Winning does not mean that you need to be a jackass. Argh!!! What an utterly loathsome way to frame things.

I aspire to achieve this level of utter contentment someday. Peak cat.

I was in the kitchen trying to make lunch when I found myself completely surrounded by two cats who have NEVER BEEN GIVEN ANY FOOD IN THEIR ENTIRE LIVES! I was cutting up watermelon!

Apparently my cats like spring water.

A lazy, crazy #caturday It must be so nice not to understand anything going on in the human world right now.

Things stink and everything is on fire but … there are still toe beans!

🧵 In 2020, I nearly died from mysterious industrial chemical exposure at my apartment. Later, I discovered my employer was dumping toxic waste into our windows from their Skunkworks semiconductor fab next-door. I tipped off US EPA, who then raided them in 2023. EPA sent me the report on Friday. 💀 ⬇️

This guy right here, the one biting the arm of the chair, walked into my daughter’s room picked up a yellow highlighter and sauntered off with it. I just found it on my bed. Well now I know what happens to at least some of our missing writing implements. They aren’t all with the missing socks.

I have laundry help! Autumn is telling her brother, “No, I am helping! This is my basket!”

Late caturday post. He is deep in the divot of an extra large beam bag and very smug about it.

Look. I care about climate change a lot. I'm close to a single-issue voter on the subject! But we have GOT to stop worrying about what are, in the scheme of things, rounding errors. I hate, hate, hate this kind of personal-responsibility climate stuff, it's deeply counterproductive.

Books take a lot of resources to make. Digital readers do, too. What's the more sustainable option? The answer isn't straightforward.

Lost my mind & starting ordering new (cheap) fountain pens and pretty ink. First up is one am a bit disappointed in - Wordsworth & Black Medium nib pen. It looks very pretty, and actually writes quite nicely (Fabriano A5 dotted notebook) but is it so slippery it is hard for me to hold for very long.

Buffalo NY area trans youth at risk call for advice. Originally plan was to wait it out & move out as soon as they turned 18, but it turns out that they have hyperthyroidism & their parents refuse to let them get treatment for it. Waiting another year and a half seems dangerous. Any useful advise?

First bloom!

The staircase at the Buffalo History Museum. I would have tried to get a better picture but all these annoying people wanted to walk up and down the stairs for some reason. ⚒️

I have help folding the laundry today. She jumped in when about when I reached the halfway point, attacked the handle for awhile and has now fallen asleep in there. Meanwhile I am sitting here with half a folded load of laundry on my lap.

Some things are still quite lovely.

So - if you opened the door of your classroom after spending some time setting up inside and find the entry blocked by a rack of chairs and a rack of tables, what would you do? I said "you know I am teaching a class in here" which admittedly wasn't the most coherent thing to say, but in return ...

Doing my updated IRB Human Subjects Research training on line and I think I am going cross-eyed. 45 CFR § 46 Subpart D applies here unless it doesn't apply here unless funded by the ED but can be overridden by 20 USC § 1232H ...except if there is a full moon and it is the second Tuesday of the month

Caturday

Peeking!

Alright, Northeasterners, youhad an earthquake!! It’s your time to shine for geos! We rarely have felt reports from your area, and they’re so important for understanding the impact of surficial geology & buildings on real lived experience. Go on, fill it out. Null reports also help!

Argh! Life is being terrible & todays topic in class was to look at current impacts of climate change (the soft version not to make college students during midterms suicidal) and also to gently explain that today's weather is actually almost exactly seasonal. March is behaving like a drunken hippo

Happy #PiDay 2024! Let's talk about the history of pi (π) and the methods used to approximate it! We start with the Babylonians (~2000 BCE), who used π = 3 for architectural projects, or in at least one instance, π = 25⁄8 = 3.128, which is within 0.5% of the actual value.

I found orange juice in the vending machine upstairs but I am mildly concerned about it.
