@jtaby Fighting SwiftUI performance is a lost battle anyway 😩…

making SwiftUI views in computed properties within views gives me the ick. it feels like it might interfere with perf optimizations in swiftui but I haven't measured. Has anyone seen any official guidance/research on this?

@jacobtechtavern Great work! Things get worse for swiftUI if grids are involved, or if there is any lazy loading… not to mention memory usage!

I put SwiftUI vs UIKit scroll performance to the ultimate test: an infinite scrolling feed full of interactive 90s GIFs. The results? Well, see for yourself...

@SebastianRoehl It is much, much slower than CoreData… for small projects using few entries it is totally fine… for large databases, the performance gap is still massive

Implementing the SwiftData models for my Pomodoro side project. This is soooo easy 👌 Lots of people saying that SwiftData isn't mature enough for "real" apps. Anyone else had problems with it? If yes, which issues did you face?

@TromboniEr21082 @Presa_Diretta con 700 euro a Copenhagen prendi una stanza, non di piú

Grazie al modello danese di #EdiliziaSociale, chiunque può aspirare a una #casa a prezzi accessibili, l’#affitto non supera mai il 30% dello #stipendio, a fare da garante lo Stato e gli stessi cittadini, in un sistema finanziariamente virtuoso. #PresaDiretta #Danimarca

@stai_laggando @Presa_Diretta Ti assicuro che é cambiato poco, anzi… 😂 non so in quale Copenhagen hanno fatto il servizio 😂… gli affitti sono il 30% dello stipendio, in 40 mq senza bagno

@Presa_Diretta Ero rimasta a pochi anni fa, Copenhagen capitale più cara e mercato immobiliare totalmente inaccessibile, nel paese con le tasse più alte d'Europa.

@vdugnist How doess ASATools report the proceeds related to each campaign?

I redesigned the ASATools reports. The default tab now includes: 1) installs, spends, and proceeds to determine if enough data has been collected 2) CPT bid and CPA goal which you can adjust 3) avg CPT, avg CPA, and LTV to help bid decisions 4) impression share to show the percentage of traffic you're buying 5) match rate to see if installs are actually coming from the keyword you're targeting 6) ROAS to quickly identify profitable keywords #searchads #asa

@wilterrero Not to be rude but this is misleading 😒. You got a spike due to App Advice and then back to near zero… this is not what good keywords ranking leads to…

Before building any app Research first. Code later My app hit 18,000 downloads, 270 reviews All from organic search (ASO) Here's why research beats coding every time: 1. I analyzed 50+ competitor apps ⌙ Found features users loved ⌙ Discovered what was missing 2. Identified untapped keywords • High search volume (8,000+ searches) • Low difficulty score (under 30) • Clear user intent 3. Built exactly what users were searching for • Not what I thought was cool • Not what tech blogs said was trending • Just what real users wanted Before: • Cool tech stack • Clever architecture • Features nobody used • 0 downloads After: • Simple solution • Core features only • Solving real problems • 10,000+ happy users Most devs build first, then hunt for users I found the users first, then built what they needed Stop coding. Start researching

@psich_en @GuizarSicairos @GuizarSicairos , is this in 3D 😮😮😮?

Ptychographic X-ray nanotomography captures the process of water filling nanoscale pores in a hydrogen fuel cell catalyst in unprecedented detail, overcoming previous limits in resolution and speed. @GuizarSicairos #Xrays brnw.ch/21wOgCc

@Jeehut @Bartozo_ @KSlazinski @Posters_App @GuidedGuestMode @RevenueCat Note the docs are a bit unclear… originalAppVersion on iOS is the original build number, not the app version 👍

@Bartozo_ @KSlazinski @Posters_App @GuidedGuestMode @RevenueCat That’s a question for @RevenueCat. Apple made it as simple as it can be.

Today I learned from @KSlazinski how to make my paid-up-front apps #Freemium without affecting existing users: 🎓 You just need to use AppTransaction.shared.originalAppVersion! Full Docs: 👉 developer.apple.com/documentation/… Will use it for @Posters_App & @GuidedGuestMode soon! 💰 ➞🆓

Very first 3D ptychographic user experiment at #NanoMAX. Impressive work by Maik @kahnt_m and by all #NanoMAX team in making this work… Thanks @jens_wenzel and @aditshuk for all the fun at the beamline!

@seanallen_dev Totally agree! Especially for small indie teams speed and product validation are more important than absolute perfection…

Don't wait for perfection before you ship. Here's how some of the biggest products on the internet got their start. Products evolve. Stop waiting. Just ship it.

@MartinLasek @matteo_spada Absolute genius 😂! This will be my reply next time I get a similar review… and it will happen 😂

@matteo_spada I’d respond: “Rumor has it, it goes away if you pay for it.” 😂

New 1 ⭐️ review for my App Explorer ➡️ apps.apple.com/us/app/store-r… How would you respond?

@SearchAds_SAO Absolutely agree! keywords in the keyword field are overrated, especially for indi apps

For iOS apps, I’m convinced that download volume is the dominant ASO factor than ratings and all other factors for improving organic keyword rankings. The keyword list in AppStore Connect is overrated. Only keywords that matter are that are in title/subtitle. #buildinpublic

Unpopular opinion: #Python sucks! For the sake of simplicity, there are too many trades-off. Now, it is clearly too big to fail. I also wondered why, at some point, we started considering explicit types as useless complexity…

Wow, twitter review turns out to be much more fun than peer review. #LK99

In case you're following the news about the supposed Korean superconductor breakthrough, there's some guys on twitch livestreaming their reproduction attempt (though nothing will happen until they've baked the stuff, 9:40 pm Pacific Time) #LK99 twitch.tv/andrewmccalip

@DDzhigaev @esrfsynchrotron @SoM_esrf @jonwright76 @jens_wenzel True, I should try and see what I get!

@Salv089 @esrfsynchrotron @SoM_esrf @jonwright76 @jens_wenzel You can add a subdivision modifier to get rid of voxel steps for smoother surfaces

Still amazed by the flexibility given by the #blender Python API. I made a small animation making the individual grains of a Ni-YSZ structure appear. This time, I used #Eeevee as a rendering engine, much faster but not ray-traced. @esrfsynchrotron @SoM_esrf

I needed a way to visualize grain orientation in 3D from 3DXRD data… so I sat down and wrote my own data format, imported it to #blender using the Python interface, and voila’ 😍 😍 😍. Thanks @jonwright76, @jens_wenzel, for the nice beam time and data!

So, I finally found a way to make the fans of my M1 Mac spin… Cycles render in #blender of a real Ni-YSZ microstructure obtained at ID11 @ESRF, using scanning 3DXRD and a tiny nanobeam of 100 nm 😏
