4.9⭐️ does not mean "this app is 98% perfect" (far from it) It means "This app is so useful that the vast majority of users gave it five stars"

Web designers: please design your websites as if users, instead of having a 100ms round-trip latency, were all living on Mars with good data bandwidth but a 20mn round-trip (sometimes 44mn). Thank you

If I launched a social media, I would make the "post" text box look very similar to the "search" text box

I finally experienced the production nightmare I had always feared: Monitoring says everything OK and numbers good, when actually the system is failing for all users

Hmm what's this spike at 18 Cloud Run instances? A traffic surge? An infinite loop in my backend code? An attack? A misconfigured autoscaler? #GoogleCloud

Best glory I’ve ever seen from a plane! It’s an optical phenomenon that occurs when light interacts in and around tiny droplets of water in the clouds, in the direction opposite the sun. More complex than a rainbow. Here’s a link to some more info: www.zmescience.com/science/phys... #optics #physics

In other shocking news, the "fastest" way to send a photo from mobile to a nearby computer is effectively to upload it to a server located in another continent, and have the computer download it from that distant server 👇

()(()( ((())) Fun fact: the first one is a palindrom

QR codes have a version, which is the resolution of the grid: v1 for 21x21, v2 for 25x25, up to v40 for 177x177. Unfortunately, QR encoders choose an appropriate version but do not expose this low-level info, and QR decoders don't expose it either.

Thank you Gemini 😅

Opinion: the "stale while revalidate" pattern should be generalized in UI, and standardized: greyed out data, refresh event, etc.) The point is to keep the UI fast and responsive all the time.

It it surprisingly cumbersome to determine the Error Correction Level (ECL) of a given QR code, as QR scan libraries don't expose this low-level info. TIL I can just visually read it 🤦 which was enough for my specific needs

There are a lot of performance considerations in Cool Maze but strangely enough, whether the requests to the backend cross an ocean to reach another region has not been one of them, so far. 👇

I was horrified reading this. In less than 10s, I had formed a plausible explanation like "selection bias", "Simpson's paradox" or "Berkson's fallacy". How could this puzzle remain unsolved for 40 years? Was the 20th century scientific culture so different? That's the real puzzle IMO

I'm working on an interactive Go 1.25 tour, but there are so many changes in json/v2 that I decided to cover them in a separate blog post. Plenty of interactive examples ahead! antonz.org/go-json-v2

J'ai été horrifié par ce passage. En moins de 10s, j'avais formé une explication plausible de type "biais de sélection" ou "paradoxe de simpson". Comment cette énigme a-t-elle pu perdurer 40 ans? La culture scientifique du 20e siècle était-elle si différente? Là est plutôt la vraie énigme, selon moi

coolmaze.io has a handy shortcut: cmaz.io So, I wanted to add the word "cmaz" to the listing in the App Store, to make it searchable from the short word. But, I may have to give 700€ to Apple first 🤔 Why? 👇
