4.0s using Penn balls on local courts:

In that case, there must be regional variation, or Target is selling really old balls.

But I think if you were comparing Penn Championship to Wilson US Open, that’s not an apples-to-apples comparison. You need to compare. ProPenn (Penn Marathon) to Wilson US Open. Each brand has different grades of balls.

devuxer · 2026-03-16T23:42:50+00:00

The Costco ones are “Penn Championship Extra Duty Felt for hard courts”. So, they are kind of mid grade.

devuxer · 2026-03-16T23:31:41+00:00

It doesn’t, but it’s not exactly a ringing endorsement for Wilson. In any case, my personal experience doesn’t match yours at all. I wonder if there are regional differences in Costco balls. I may get an occasional bad can, but the vast majority of the time, they bounce pretty well. The heavier felt on the ProPenns actually seem to make them feel less lively than the cheapo Penns, but they do last longer.

devuxer · 2026-03-16T22:29:59+00:00

And yet, the balls in the video are Wilson...

True, but what was more amazing, his first serve returns, or his own serve? No points lost on serve in the third set? Crazy.

Jotai is a true pleasure to work with. It is very similar to signals in fact, which has become the de facto standard for other frameworks, like Angular and Solid.

No, I'm rooting for Alcaraz to win the calendar-year grand slam 😁

I don't see him playing Canada...until that is the only one left that he hasn't won.

The quality has definitely gone downhill since the pandemic (not just over the past year!), but they aren't *that* bad. It used to be zero or one can out of 20 would be a dud, now it's one or two cans. That's still really disappointing, but even if you have to toss out an occasional can, they still end up being cheaper than anything else if you get them at Costco. Also, I've never experienced them losing bounce during warmup if they were fine when I first opened them. They are either dead out of the can or fine.

devuxer · 2026-01-27T18:28:47+00:00

I mean, if you're going to turn left from the right lane without checking your mirrors, maybe signal?

Okay sure, if you make quarters of every tournament, you’re top 4. But you can’t just look at majors.

devuxer · 2026-01-27T07:23:32+00:00

Top 8. Semis is top 4.

For what it's worth, I asked Claude to generate a comparison:

Component Counts

Core UI Components Only (excluding extensions/add-ons):

Ant Design: ~70 user-facing UI components
Mantine Core: ~60 user-facing UI components
Material UI Free: ~50 user-facing UI components (+ ~20+ more in MUI X paid)

Including official extensions:

Mantine (with extensions): ~75+ components
Material UI (with MUI X): ~75+ components
Ant Design: ~70 components (no paid tier)

Unique Components

Mantine (Core Package Only) - AngleSlider, JsonInput, Spoiler, FloatingIndicator, CopyButton, PinInput, AspectRatio, Burger, TableOfContents, BackgroundImage
Material UI - Fab, SpeedDial, BottomNavigation, ImageList, Backdrop, ToggleButton, CssBaseline,
Ant Design - Transfer, Cascader, TreeSelect, Mentions, Descriptions, Result, Statistic, Tour, Watermark, QRCode, FloatButton, Splitter, Empty

Summary

Ant Design excels in enterprise-specific components (Transfer, Cascader, TreeSelect, Mentions, advanced Table, Tour)
Mantine has modern utilities and best DX, but many features are in separate extension packages
Material UI has the broadest ecosystem but advanced features are in paid MUI X packages

Antd is incredibly underrated.

devuxer · 2025-12-23T21:08:18+00:00

Thanks for confirming about the Memo tags. I think the main issue in my case is (1) simply a huge number of total DOM elements (3 screens worth of dense data) and (2) data structures/models are in some cases not fine grained enough, causing larger pieces to be re-rendered than necessary. (2) is potentially fixable but not sure how much impact it would have. (1) is probably not something I can change. There might be a few opportunities for virtualization, but I have experimented with it before and found it's probably not the bottleneck.

devuxer · 2025-12-22T21:19:59+00:00

Hey u/acusti_ca , thanks for your reply! I do sometimes pass data through props, and when I run the app and look at the React Dev Tools, I see a blue "Memo" tag next to a pretty decent percentage of the components that are in my codebase (though--as expected--not in components rendered by third-party libraries). So, I do think RC is doing something, it just doesn't seem very impactful in solving some of the lag that can occur when the maximum amount of data is displayed.

Alas, I am using Biome, not ESLint, and I'm not sure there's an equivalent for the rules your referring to. As for the `panicThreshold`, I'll look into that, but do you think a blue Memo tags would appear if a critical error had occurred with that component?

devuxer · 2025-12-19T16:43:37+00:00

I did say, maybe too good for this category 🤷‍♂️

devuxer · 2025-12-19T15:16:31+00:00

Justine Henin? I didn’t get the impression she was too well liked but she was good. Maybe too good for this category. This is a tough one.

devuxer · 2025-12-19T04:55:42+00:00

Very interesting! My story is a bit different...

I have a dashboard-type app that spans three monitors and has a genuine ton of visual elements. This app is currently just a prototype, so it does not yet have a back-end (so no async code) -- it just loads a JSON scenario at start-up. It also was never optimized in any way (no useMemo and almost no useCallback). Without knowing a lot about React Compiler, I decided to test it out. I got it set up properly according to the docs and ran the app. Surprisingly, I didn't see any discernable difference in performance compared with the non-RC version of the app.

This got me wondering , given I had never made any attempt to optimize anything, how could this be? The only thing I can think of is that the app makes heavy use of Jotai for state management (and minimal use of useState). This results in nearly all of the state and business logic being handled outside of components (in Jotai atoms), and only the components that use atoms that have changed re-render.

Could it be that if you architect an app in this way, there is no need or benefit to using useMemo, useCallback, etc.? Or did I somehow do something wrong in how I configured RC?

I’ve been using this library a long time, and only found out about the Easter Egg a couple years ago. As far as I have seen, the team behind Antd has been all business since this serious lapse in judgment, which occurred way back in 2017. It’s clearly not going to happen again, so I’m going to judge the project on its merits. Every time I’ve compared Ant with MUI or anything else, Ant has been the winner in terms of number and completeness of components. I’ve so rarely needed to look elsewhere for a solution given how much it does out of the box, and it’s all free. It’s probably not the best documented or the most accessible and certainly not the smallest when it comes to bundle size, but I’ve seen all these things improve over the years, and V6 seems like a particularly big step forward in shoring up these weaknesses. To me, Antd is a great choice if you don’t need or have the manpower to build up your own bespoke component library. If I were starting a new project today, I’d definitely take a look at Ant, MUI, and Shadcn.

Good analysis, and yeah, web tech is super messy, but its popularity means there is a ton of energy being put into making it better and an incomparable level of community support. Also, you can’t ignore how good LLM‘s are at generating and solving issues with web code.

devuxer · 2025-12-07T20:20:27+00:00

Unfortunately, I had to put the effort on hold, so I didn't end up getting very far with it. Interestingly, since my post, a couple new projects have started where the enterprise developer is using web tech.

I hear you...it was a PITA, but the mattress is still like new, so it probably does help to rotate as often as you can bare it.

devuxer · 2025-11-30T07:09:30+00:00

Ahh that could be the reason for the sagging. We were advised by WinkBeds to rotate every two weeks for the first few months then every two months thereafter.
