I was with them up until the diagram where the straight lines seemed much better. Not that it distracts from the main argument. It might just be that I expect straight lines on diagrams like that and not curves

I thought the same exact thing. I feel like if anything, it obscures the implied relationship between B and C

do I have some sort of condition? not one point in there made sense to me. "which is easier to look at?" they're both the same, to me. one is pointier, the other rounder, but that doesn't make one easier to interpret than another. UX people are mostly high on fresh MacBook packing material fumes I think.

A lot (all?) of design is signaling. You don't have a condition, you simply haven't been conditioned to reflexively shibboleth.

Funny last week we removed all the rounded corners. We set a border css variable so all the border rules became border-radius: var(--border-size); We figured this way every 6 months or so we could switch between squares and rounded edges... This may provide little design pops to give a fresh feeling to users... we'll see so far it feels very fresh to me.

How can you write an article on rounded corners without mentioning Steve Jobs and Bill Atkinson? https://www.folklore.org/StoryView.py?story=Round_Rects_Are_...

I'm "old", but I know that not every article about X has to be full history of X.

Well sure, but the first sentence of the article is practically the title of Andy Hertzfeld's post. It would have been perfect for a link at least.

On the other hand I have a deep hate for things rounded in 3 dimensions for physical objects. They look cheap. Round in 2 but not 3 dimensions.

A few months ago, I built matching houseframe beds for my 2 year old grandtwins (https://www.woodshopdiaries.com/diy-kids-house-bed/).

The best piece of advice I got from my dad before I started on this (for me) ambitious project was in question form: "Are you going round over all the edges? A 1/2 inch round leaves a bruise on a little one. An unfinished edge leaves a cut."

He's been right. They're psycho 2 year olds who think monkey behavior is the best. I've watched them bonk multiple times on facetime. No cuts, just a rub at the bonk spot.

We see this in product design all around us. Sharp corners cuts and hurts us. So we tend to round things over. And when we use software interfaces, I think the rounded corners engender a "this is safer" sub emotional response, and therefor more approachable.

You still want fillets or chamfers in 3d. Properly sharp edges in any dimension will still hurt you and catch on things

Rounded corners look more sturdy and robust. Objects with sharp angles are easier to break. External corners are easily damaged. Metal corner guards for cabinets are often rounded, and that makes them not only safer for people but also rugged. Internal corners concentrate stresses, making it easier to start a crack and break the object. Sharp corners are easy to produce, requiring less tooling, and so look cheap.

> Sharp corners are easy to produce, requiring less tooling, and so look cheap. An artifact of modernity, surely? Historically, tight, neat corners required large amounts of skill and the right tools to create, whereas there were many approaches to rounding-off an arbitrary corner or edge.

Since the advent of the milling machine, but it's been around for a long time down.

I guess really it's from the age of the saw or file. Making sharp corners isn't particularly hard to do

> We can all appreciate the aesthetic beauty of rounded corners. Can we? Much like that top 40 song that comes on the radio way too often, I have come to find all the rounded corners off-putting. They are usually a signal of form over function, and often used by information sparse sites. Give me square corners like HackerNews, old Reddit, or Vanguard any day.

I kinda like the notched corners of Battlestar Galactica, personally. Though I always did wonder what happened to all the triangles...

Taking triangles off a corner is called a chamfer. If you're cutting it off, the material ends up on the floor or vaccines up, then recycled into new stock

Earlier quoted context omitted.

Yep, https://en.wikipedia.org/wiki/Castle_Fortress_of_Almeida

Worth noting that in addition to the ability of defenders to see every part of the wall, star forts have the advantage of making artillery fire more likely to hit the wall at an oblique angle, reducing the odds of a direct hit and (probabilistically) reducing the energy imparted to destroying the wall.

There's a trade-off: it takes much more masonry to enclose the same amount of space.
