So we should really prohibit the closure from callingwithagain. We could add some runtime assertion that panics when the active table is not recursive mapped anymore. But a cleaner solution is to split off the mapping code fromActivePageTableinto a newMappertype. 🔗Refactoring We start by cr...
I've written 3 tutorials to show you how to create a service enabled Android application that performs all of it's network I/O in a background thread (not the UI thread). These tutorials are split into three parts. This tutorial shows you how to use background threads to perform long ...

Since implementing a dedicated viewmodel renderer system back in April 2021, all of our viewmodels have been split between the old and new system. The primary stumbling blocks were viewmodels with lots of particle effects and lights (torches, flamethrowers, etc). While we covered most of the ...

You will deep dive into Reactive programming, asynchronous programming and split our web application into a set of concurrent actors. The book provides several highly accurate HTTP-handling examples with manageable memory allocations. You will be walked through stateless high-performance microservices ...
If we want to handle unlimited cardinality, the split structure of inverted index and time series would need to change. However, this structure is core to how the database is designed. Strict memory control requirements make a refactor difficult as well. This means we can’t use MMAP, which...
