If your app is slow on some devices or Android Studio’s Instant Run features stop working randomly, then you might be experiencing memory leaks. When Does A Memory Leak Happen? One of the great things about Java is garbage collector (GC). A garbage collector runs periodically to check objects that are not…
Ever since I started developing for iOS, I have been working exclusively on mobile apps. I didn’t have any real experience shipping an SDK, other than HMSegmentedControl, which doesn’t really count as an SDK. I recently became a Product Owner at Instabug, where I also lead the iOS team. We build an SDK for bug…
Having answered the question of why we don’t use Swift at Instabug many times over the past few months while doing interviews (P.S. We’re hiring), I decided to write a blog post. Since Swift’s introduction in 2014, it has matured a lot. We no longer read the stories of how unstable the compiler is, or…
“Instead of this absurd division into sexes they ought to class people as static and dynamic.” – Evelyn Waugh The standard Objective-C introduction usually mentions its Smalltalk heritage along with its strict C dependence. So how can a language running over the hallmark of procedural programming be dynamic? The Objective-C runtime. It’s the only…
Building mobile applications with web technologies greatly speeds up development, as well as the added benefit of shared code between platforms. Sometimes, however, you need capabilities that aren’t available in a web view, or maybe implementing will require too much work. That’s when you break away from your cross-platform heaven back to native development. Here…
While we were working on speeding the run time of our specs, it came to our attention that the Paperclip gem contributes a fair amount to the slowness of the specs, mainly because of its dependency on external software like ImageMagick’s convert and identify; and Unix’s file. Shelling-out may not be this slow, but when…
