> windows should be square

found the Windows 8 enthusiast! haha, I kid. (I myself use a tiling window manager , i3, with completely square windows without any gaps or rounding)

doubled112•1h ago
Haha, Windows had square windows long before 8.

If I could run the Windows 2000 UI on a modern OS I would but any recent clone/theme/etc feels too uncanny valley.

paulddraper•1h ago
Not having i3 is truly the worst part about Macs.

(Yes, please tell me about some buggy half-compatible tiling window manager for my Mac.)

porphyra•1h ago
For real. Doesn't help that the three/four finger swipe between full screen windows/workspaces has a mandatory animation that you can't disable (you can turn on "reduce motion", but it simply changes the scrolling animation into an equally time-wasting fading animation).

I like rounding the corners on i3. It is a bit wasteful but the base WM is so efficient with my pixels that I have some to spare.
dsr_•1h ago
My custom XFWM theme has square corners on windows without focus and large-radius rounded corners on the one window with focus.

The square corners are part of a 2 pixel wide border (one black, one white) because who needs to waste space on handling things we aren't manipulating? But the title bar is high-contrast, because you'll go looking for it when you want to switch windows.

The round corners go with a fairly thick border in a customizable color, usually something very bright in the yellow, orange or cyan ranges. When you sit down, you should immediately know what is active.

In response, I expect the open-source community to make an optimal square packing window manager. https://en.wikipedia.org/wiki/Square_packing
sublinear•1h ago
Nope. Virtual windows are rectangular because the screen is also rectangular while being small enough to see the edges within our field of view.

They don't have to be any particular shape or size. The property of being virtual overrides everything else when free of these self-imposed constraints.

Even if you lose the GUI and go back to text, the ideal terminal is a plane of infinite columns of arbitrary cell size that dynamically fills your field of view.

I'd further argue that the only reason VR/AR isn't more widely adopted is the lack of orthographic vs perspective modality per application (and uncomfortable headsets). In VR/AR, you don't want a window manager or even windows at all. What you want is a field manager (as in FOV "fields" of varying opacity that can be composited by the user). Shape and size is just an arbitrary region blended in with the environment.

For the sake of ergonomics, you'd more often prefer to project an interface onto a surface if you had the choice. When you don't, you probably want the projection to be orthographic, but for the edges to be fuzzy if not invisible. You'd generally want to be able to layer these interfaces as well instead of having opaque rectangles always in your way.

imiric•51m ago
I don't think GP was advocating for actually square windows. Rather that the corners should be right angles.

This makes perfect sense considering that most LCD displays, and practically all computer displays, don't have rounded corners. This trend of rounding displays and GUI elements is purely an aesthetic choice. I also find this obnoxious since the only thing it does is rob me of a few pixels which are often useful.

But considering Apple users have accepted living without a large block of pixels dead center at the top of the screen, which they've been sold as a "feature", the rounded corners are likely even less of an issue.

I'm not sure that an infinite plane of pixels makes sense even in XR. I want to see a clear edge of where digital content begins and ends, and a rectangle is the simplest and most optimal shape for that. So I would rather have physical display-like floating rectangles, than floating text in arbitrary locations, or rounded off corners for the sake of aesthetics. I'm not opposed to a very slight rounding off of edges on certain elements, but the trend Apple is pushing is supremely ridiculous.

sublinear•16m ago
Yeah I don't think we disagree. I just think you all's preference for windows, tiles, etc. (anything rectangular and opaque) is rooted in an idealistic efficiency of pixels just as unergonomic and frustrating to everyone else.

I'm saying that there is room for your arbitrary preference for opaque rectangles if we all abandon the notion of a "screen". We are well past the point where we can do this economically. It only persists because of consumer acceptance. Traditional screens are less efficient in every tangible way. They are less power efficient for their apparent brightness and require more material to construct.

Even the notion of clear boundaries and pixel size is an illusion. Traditional screens only make the pixels so big because they require sufficient brightness and power to see them at that distance, not because we cannot manufacture smaller pixels for cheaper. We could have much better results for everyone and the only remaining cost/problem is finding a way to comfortably wear the display.

Square sensors ought to be more common because they maximize the field of view for a given lens. Well, apart from circular sensors.

LG sells a DualUp monitor that is 2560x2880, same size as two 2560x1440 displays stacked on top of each other: https://www.lg.com/us/monitors/lg-28mq780-b-dualup-monitor
layer8•40m ago
Yep, though what I would want is the width and height swapped. You can rotate the monitor, but then the subpixel layout isn’t good for text.
marssaxman•5m ago
That looks genuinely useful - I could see positioning a monitor like that on either side of my main monitor, at an angle, and using them for docs, reference material, slack, calendars, etc. All the screen space of a dual-monitor setup, without the separation right in the center! Ah well, shame they're no longer made.

Hmm. Android uses the curvy bits for status so the main area is rectangle. So it is OK. It has the advantage of curved corners on casing to reduce chance of cracking screen on a drop.

abujazar•1h ago
Yea, that's ugly. I'm sure it could've been done more gracefully with 15 minutes more effort. But judging from the general wear and tear on this poor Mac I guess they don't even consider the resale value.

Seriously, I have several mac laptops dating back to 2004 and they all have less wear than that.
bee_rider•1h ago
I think he is not worried about the resale value.

> This was on my work computer. I expect to similarly modify future work computers, and I would be happy to help you modify yours if you need a little encouragement.

I don’t understand the actual decision but I appreciate the gusto with which it was made.

hk1337•1h ago
The main reason to consider resale value is 1-2 years later you may want to upgrade and selling it to another person typically yields you more money than trading it in with Apple. Doing something like this may decrease how much you could sell it for later.

If you’re not planning on doing that then it’s not really a factor for you.

kibwen•1h ago
I can't even imagine prioritizing resale value here over one's own comfort. The purpose of a tool is to be used, not to serve as an asset class.
abujazar•1h ago
Sure, but comfort != abuse :D Apart from the filing, I can't think of ways to make such a recent Mac look like this. Did it suffer a plane crash? Acid attack? Thermite fire?

I appreciate the customization, but would probably make an effort to make it not look like (another) accident.

Doing this to a work computer seem a bit questionable from the ethical standpoint.

Totally fine to do whatever you want to your personal belongings though.

My work computer is missing two keys and has been since they signed it out to me.

I don't think there's anything inherently autistic about that. We just finally have these technologies sufficiently mature that materials and design are no longer strictly dictated by their function.

convolvatron•1h ago
if you want to do this, there is a better technique than shown in this video.

get a single-cut fine file, maybe with a little more weight than the one in the video. single cut file has diagonal slots and allows firm and continuous contact with the piece. most files are double cut, have two sets of slots and look like bumpy diamonds. they remove more material but tend to bounce.

use long even strokes with firm pressure, only during the fore stroke. watch out for roll-off, where you unconsciously change the angle or pressure of the file as you're at the end of the stroke.

you can make a pretty even-looking chamfer that way.

powvans•1h ago
Nitpicky, but he’s rounding the edges, not the corners.

And yes, why are they so sharp?

I seem to recall my wife having the plastic MacBook that came out circa 2006 and the edges on that thing were legitimately painful.

I always marvel at how sharp the points are on the notch of the lid on my current MacBook. Very very pointy.

forrestthewoods•1h ago
why? Because Apple hates you and wants you to suffer.

Alternatively, because they care about aesthetics more than utility and comfort.

>it is uncomfortable on my wrists

Are your wrists supposed to be coming into contact with that? I suspect many of us have bad posture and do rest our wrists like that, but if your concern is wrist comfort, you probably want to consider that you're going out of your way to enable harmful posture.

The Apple Watch Ultra also has an aggressively sharp screen edge. It's kept me from upgrading from my current watch (Model 8). But maybe I would get use to it?
gensym•1h ago
The side that faces your wrist is rounded - only the face is sharp. I haven't noticed any issues with the edge wearing the thing.

I was worried about scratches because I abuse the shit out of anything I wear, and sure enough, there are scratches in the titanium bezel, but they look good in a way that scratches on my (non-pro) steel Apple Watch did not.

There's a significant lag between the longer days and the resulting higher temperatures though, which does make the seasons make more sense temperature-wise.
kokanee•1h ago
The seasons idea is interesting -- to me, both proposals feel wrong. I think it's because the weather changes that I perceive seem to lag behind the changes to daylight length by a few weeks.

I would propose boundaries that align partly with how I perceive the weather, and partly with how we plan our year (by months): Summer starts June 1st, Fall starts September 1st, Winter starts December 1st, and Spring starts March 1st.

Oh, I have never heard of seasons starting mid-month. My mind is blown!

In Australia it's just split up by months, with each season being 3 months long:

March 1 - Autumn starts June 1 - Winter starts Sept 1 - Spring starts Dec 1 - Summer starts

Of cause, those in far northern Australia, only really have Dry and Wet seasons. I have no idea when those are.

LeoPanthera•49m ago
Part of the reason for this is that climate lags behind sunlight a bit, so the end of the authors "summer" would be warmer than the beginning.

But most countries other than the USA use meteorological definitions of the seasons starting on the 1st of December, March, June, and September.

Macha•15m ago
On the seasons front, traditionally in Ireland winter starts on Halloween (at sunset if you want to be really specific), and so you get winter is November till January, spring is February to April, summer is May to July and autumn is August to October.

That said being an English speaking country and absorbing a lot of media from other English speaking countries, there’s been a slow drift towards the American system making its way in, so younger generations are more likely to use American seasons and older people more likely to use traditional seasons, though you’ll find people of all age groups using either. Certainly they taught the traditional seasons in school when I was a kid, I wonder which they teach now.

(Of course, you could make yet another system based on the weather where summer is approximately two weeks in July, winter is a thing that happens every few years and the rest is a sequence of mild weather with occasional wind and scattered showers)

I thought this was going to be on a softwarefix for the appalling inconsistency that are macOS Tahoe window corners.

Good on op for doing something they like, even if it's really out there and I could see more "pillowy" hardware becoming a thing now, after a few years of sharp edged devices.

Since I mentioned Tahoe, it bears repeating, my spotlight is still broken.

- Sharp edges eat into my forearms.

- Glossy screen makes it hard to see when it's light out.

- An arrogant desire to obsolete ports.

Love this! I did this in 2020 and until today I hadn't seen anyone else who had done it. If anyone is tempted, I recommend finishing the job with Micro-Mesh. IIRC, I went up to 12,000 grit and it results in a nicely polished look that catches the light beautifully.[1] I bet it would look even more striking on the actual black MacBooks we have today.
