Jarmsy··on Show HN: Make cursed fonts like Times New Bastard
What's the actual process that leads to this look in reality?
Jarmsy··on The Beauty of Roundabouts
In England we even have roundabouts of roundabouts https://en.wikipedia.org/wiki/Magic_Roundabout_(Swindon)
Jarmsy··on Apple's Dimensional Drawings
Rhino runs natively on Mac
Jarmsy··on Study: Blue light impairs the eye's ability to distinguish fine detail most
Here's a neat demonstration of this https://www.schulz-hildebrandt.com/9-purple-dots-illusion/ (I find the effect works much better on my phone screen than desktop)
Jarmsy··on Angels in Coptic Magic I: Introduction
I clicked the link fully expecting 'Coptic Magic' to be some obscure software framework, and 'Angels' some new feature in it.
Jarmsy··on Kimi-K3 on HuggingFace
Let's just go with YM/DY/MD (27/26/07)
Jarmsy··on Can you stop beans from making you gassy?
Disappointed not to see any mention of epazote.
Jarmsy··on Buttered Crumpet, a custom typeface for Wallace and Gromit
Wensleydale is a place in Yorkshire, and a style of cheese, not specific to any one brand, so you could.
Jarmsy··on Two days of oatmeal reduce cholesterol level
Chestnuts?
Jarmsy··on Two days of oatmeal reduce cholesterol level
It looks like this study is not just about the effects from the soluble fiber in oats though, but their specific effects on the microbiome.
Jarmsy··on Two days of oatmeal reduce cholesterol level
2kg in 2 days doesn't sound unreasonable at all. Glycogen and water loss from the calorie restriction will do that, along with maybe better bowel regularity from the fiber. Nobody is claiming they lost 2kg of body fat.
Jarmsy··on I'm making a game engine based on dynamic signed distance fields (SDFs) [video]
Sampling an implicit function on a grid shifts you to the world of voxel processing, which has its own strengths and weaknesses. Further processing is lossy (like with raster image processing), storage requirements go up, recovering sharp edges is harder...
Jarmsy··on Simple 3D Packing
2d packing is still a hard problem
Jarmsy··on Learning music with Strudel
Increase the duck attack!
Jarmsy··on Tiny sugar spoons are popping up on NYC fast-food menus
As a non American some of these numbers are just mind boggling. Only putting the warning on drinks with more than 50g of added sugar, a 'medium' Dr Pepper with 67g of sugar and a large with 96g.
Jarmsy··on Offline card payments should be possible no later than 1 July 2026
I don't think they do, people move around and swap seats. I expect they just find the losses small enough to write off. I was once travelling shortly after being issued a new debit card, but still had the old one in my wallet and used it by mistake and I wasn't charged. They never tracked me down for the cost of that packet of crisps!
Jarmsy··on A statistical analysis of Rotten Tomatoes
I often enjoy movies that are unexpected and don't fit neatly into one established genre, but I think these tend to get lower audience ratings, while films that deliver to expectations do better, even if most of a randomly selected audience would dislike them. If a movie is a comedy, with a poster with big red letters and a white background, people know it's a certain kind of movie, and mostly those who enjoy those movies will go see it. Likewise with documentaries about some niche interest - those who watch it mostly sought it out because they're into that.
Jarmsy··on Dicing an Onion, the Mathematically Optimal Way
When cutting potatoes into chunks, for something like a stew, I often find myself thinking about this problem, and how I would write a program for a robot to do it.

They are fairly well approximated as ellipsoids of different sizes. Typically, I want pieces around half the volume of the smallest potatoes, but with the range of sizes, this means cutting the larger ones into at least 5 pieces. While it would be simple to make parallel slices giving equal volume, these would have very different shape to the halved smalls. Some can be quartered to give nice chunks, others into thirds with 2 perpendicular cuts...

Jarmsy··on What does it mean to be thirsty?
That was one part of the article I found questionable- "If the body needs salt, those chips will cause a surge of pleasurable dopamine to flood the brain. If the body doesn’t need salt, that dopamine drip disappears"

Surely this second part is false? Most of us have got used to high levels of salt in modern diets, and prefer the taste of salty things even when we've had way more sodium than we need.

Jarmsy··on Coronary artery calcium testing can reveal plaque in arteries, but is underused
Don't statins calcify plaques? So presumably being on statins would raise the score?
Jarmsy··on Aging-related inflammation is not universal across human populations
Eat them while they're still alive?
Jarmsy··on Biomolecular shifts occur in our 40s and 60s (2024)
"in the sixties when many go in rent" autocorrect from 'into retirement'?
Jarmsy··on Cannabis scientists are trying to find a predictable, reliable product (2020)
That was not my experience at all when I used to drink, and I don't think I'm alone in this. The feeling from different alcoholic drinks differed significantly.
Jarmsy··on Continuous glucose monitors reveal variable glucose responses to the same meals
I definitely see effects on my glucose the day after when I change my exercise routine, such as doing an extra LISS session. Anticipation of something stressful or exciting does also have an effect. I haven't noticed any effect from simply expecting more exercise later (without emotions attached). I believe a lot of this comes down to liver and muscle glycogen storage and release. (I'm T1)

And one reason for taking B12 is actually to prevent neuropathy.
Jarmsy··on Cross Views
Found it http://eyestilts.com/intro.html
Jarmsy··on Cross Views
I remember reading about a physical device someone constructed with mirrors (I think at an early burning man) that gave you the experience of a huge inter ocular distance to get a giant's eye view. I've always wanted to try one (or the opposite to experience a tiny inter ocular distance).
Jarmsy··on Rediscovering Quaternions
I have noticed too that HN has an enduring fascination with quaternions, and they seem to reach front page surprisingly frequently (considering that there's not a huge amount of discussion of other geometry topics). I'm certainly not complaining though - I love quaternions too!
Jarmsy··on Generating Voronoi diagrams using Fortune's algorithm
A few years back I made this 3d visualisation https://x.com/KangarooPhysics/status/1253336959755251716
