Grab's configuration management SDK was crushing service performance with memory spikes and CPU throttling. 98% of services were loading 100x more data than they actually needed.
Real User Monitoring isn't just a performance tool. It's the bridge between what you think users experience and what actually happens in production.
SwiftUI or UIKit? The iOS dev community is split, and new grads are caught in the middle trying to figure out which framework will actually land them a job.
What if you could ditch Xcode's sluggish editor and use VSCode/Cursor for iOS development? Turns out, you can build a surprisingly functional setup.
