Re: Theory on the VPN 6 Days Ago by Liam91 Sounds like you're diving deep into how tunneling apps work! These apps often use VPN-like methods to route traffic through servers, sometimes exploiting free access points. Configs like .hat may include encryption keys or payload setups. Keep exploring... lots to learn! Re: How Does Flutter Handle State Management Internally? 1 Day Ago by kearawill No, It is not AI generated. Re: How Does Flutter Handle State Management Internally? 1 Day Ago by sophiabrooks Flutter internally handles state management through a combination of mechanisms: Stateful Widgets, declarative UI updates, and various libraries for managing app-wide state.

When an app’s state needs to be updated, Flutter takes care of rebuilding only the UI components that require change when setState() is called on stateful widgets. This allows the framework to re-render the important widgets and not all the widgets on the screen. For more … Re: App development - Lobby functionality optimisation 2 Weeks Ago by jonathannweyer Since you’ve already tried caching and reducing network calls, you might want to look into pagination or lazy loading to avoid loading all rooms at once. WebSockets can also help by pushing updates instead of polling. Make sure your backend queries are indexed efficiently, especially for filters like player count. If the lag happens mostly during … Re: How Does Flutter Handle State Management Internally? 1 Week Ago by kearawill How Flutter Handles State Internally Flutter uses a reactive UI model. When the setState() method is called within a StatefulWidget, it marks that widget as "dirty" and schedules it to be rebuilt in the next frame. This allows Flutter to efficiently update only the parts of the widget tree affected by the change, thanks to its … Differential Directory, indexing method 1 Month Ago by xrjf **Features:** * Retrieves the differentiating bit of a key with respect to the previous one and … concept, but instead of letters, it identifies the first differing bit between keys.

Re: Differential Directory, indexing method 1 Month Ago by rproffitt DiDi appears to be some China based UBER service but then again I can't find a question or much else to discuss here. Re: Differential Directory, indexing method 1 Month Ago by xrjf About DiDi DiDi (Differential Directory) was originally developed as part of my thesis project in the early 1990s. The name bears no relation to the more recent Chinese ride-sharing company. At the time, DiDi was a novel approach within its academic context, but a change in legislation unfortunately led to the closure of the school and the … Re: Differential Directory, indexing method 1 Month Ago by xrjf For example, as Donald Knuth points out in The Art of Computer Programming, the theoretical lower bound for comparison-based sorting algorithms is K × log₂(N). I developed a very simple method that matches this performance. However, DiDi goes far beyond: its performance is proportional to K × (maximum key length), regardless of the number of … Re: Differential Directory, indexing method 1 Month Ago by xrjf As an illustration, consider the theoretical lower bound for comparison-based sorting, as stated by Donald Knuth in The Art of Computer Programming: K × log₂(N). I developed a simple method that matches this limit. For example, to sort the list {2, 5, 7, 1, 4, 3, 8, 6}: Sort pairs: (2, 5) → [1] (1, 7) → [2] (3, 4) → [3] (6, 8) → [4] Merge… Re: Differential Directory, indexing method 1 Month Ago by xrjf "Just to clarify a previous mistake: the efficiency should be K × N × log₂(N), not K × log₂(N) as I initially wrote." Re: Differential Directory, indexing method 1 Month Ago by xrjf I've just made an update because some records weren't being added properly. The issue was that the form didn't take into account that the register field (in the call to DiDi) is passed by reference. Re: Differential Directory, indexing method 1 Month Ago by xrjf Just a quick update for anyone interested: I have revisited and significantly improved the code, aiming for a more professional structure and better performance. The updated version avoids freezing the UI during long operations and follows more robust programming practices. If you’d like to see DiDi in action, there is also a video …
