Seriously. My advice to all, if you see "Kleppmann", click the link.

Definitely, and it's probably not very noticeable, but there's no escaping the physical problem of not a perfect 1:1 or 2:1 pixel ratio.

Say you have a UI element that's supposed to be 9px wide. If you have perfect 2:1 pixel ratio you can use 18 physical pixels and it's as sharp as the monitor can be. If you're using UI scaling of say 1.5, the monitor needs to use 13.5 physical pixels to render it. Except that's not possible, so it will average together the 13th pixel with the 15th pixel (simplifying). It's basically introducing an extra anti-aliasing pass to your frame. This is is why the Apple/LG 24" is 4k and the 27" is 5k. All that said, I'm sure 4k @ 27" even with 1.5x scaling still looks great and you'd never notice the difference, except if you had the two right next to each other.

I think this always applies. For instance the border on this textarea is 1px. There's nothing the OS can do, it's a physical issue. If UI scaling is 1.5, the correct answer for the size of the border is now 1.5 physical pixels. The best you can do is color the first pixel black and the second pixel the average of the first and third pixels. I might be wrong on this but I can't imagine what else it could do (other than mis-sizing the element).

I do agree that it probably looks fine and you wouldn't actually notice, unless you had an @2x monitor right next to it (of which there are sadly very few options)

I don't think that's possible? Say if you had a perfect 1px wide black line @1x and then you change UI scaling set to 1.5, you now have a 1.5px (physical) wide line. Which means you'll get blurring.

I suppose if you put it quite far away, a 27" 4k @2x scaling would work well. It'd feel like a 24" 1080p monitor with retina sharpness.

For all the folks confused why I'm saying you don't want a 27" 4k monitor for text, it's because the PPI isn't nicely sized for 1x or 2x, which means you have to set it to scaling that rounds and blurs subpixels.

By the way, I'm sure most 27" 4k monitors look fantastic and you should enjoy them! Especially if you don't mind or notice the scaling rounding or if you run it @2x and like the 1080p real estate.

What scaling do you run it in? If you do @2x things are massive for my taste and you don't have enough screen real estate (same space as 1920x1080).

If you go to true 2x scaling, things will be the same size as 1920x1080@1x on a 27". For me, that's HUGE and you don't get enough screen real estate for a 27". If you use 1.5x scaling you will lose sharpness because things won't line up to pixels perfectly.

For text rendering, 4k doesn't really work for 27" or bigger. It'd work for 24" because you could do true @2x, but there aren't many out there. For 27", besides the UltraFine 5k, I'd prefer just using @1x with 1440p too.

"Usually, I hear that from people who build an app/product/software without a market validation"

It's an argument against using the quote to suggest that you don't need to validate ideas against real users.

Just that if two people make changes at the same time on different clients, I don't have much control over merging those changes together with Firebase (that I know of). I think it's just a "last change wins" type system.

Just a counter datapoint, the Firebase comparison is what got me to click on the link and check it out. I'm a huge Firestore fan... here's what would get me to try something new:

- Better user permissions, ability to actually see my users and user permissions in a UI

- Better ability to choose conflict resolution logic

- Tied to that, ability to get "patches" from the server... right now if a change happens in my Firestore document, the server sends the entire document to the client. I'd love to be able to get a patch with just the changed data (and of course send patches to the server too, which it looks like you would support).

- Join queries to save me from needing to do multiple client -> server trips. If it's SQL I'm guessing you would support this.

Very interesting project! I'll be following your progress.

Good tips... setting timers really helps me. It's mini-accountability.

Start a timer and say "I'll finish this task in 30 minutes". It helps my brain skip the random "new tab twitter.com" behavior.

Nice! Love the idea, the visuals and the music.

It feels weird to press right to go left when you're on the underside of a box (though I understand why, and not sure what the alternative is). Most of my deaths were due to pressing the wrong direction when I was clinging to the bottom of something. Maybe with more levels I would develop muscle memory for how that works.

Also, I pressed 'feedback' after the end, and when I came back the option to subscribe to the mailing list was gone!

Overall, very cool! Looking forward to seeing more.

Hopefully helpful feedback from someone interested in this kind of thing:

1) I was assuming "Get Started for Free" means there's a free trial followed by a subscription fee type service.

2) It would go a long way to have a little more content (in terms of pics or specifics about the program) to tease sign-ups. The sign-up wall came a little too soon, before I felt interested enough to continue.
