Re: Differential Directory, indexing method 5 Days 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.

Re: Differential Directory, indexing method 2 Weeks 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 2 Weeks 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 2 Weeks 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 2 Weeks 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 Week 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 Week Ago by noahevans This is a brilliant explanation of how Differential Directory (DiDi) indexing works — very efficient and elegant. The idea of storing only the first differing bit between keys reminds me of how we optimize systems for speed and memory, much like how some tech repair services streamline diagnostics.

Re: Text Classification and Summarization with DeepSeek R1 Distill Llama 70B 2 Months Ago by policenbicleara Llama-70B struggles with sentiment analysis (69% accuracy) vs. Qwen-32B (87%). Summarization performance is weaker, with lower ROUGE scores. Qwen-32B is the better choice—smaller, faster, and more accurate.

Re: Buggy career talk :-P 1 Month Ago by Reverend Jim The most challenging bug was one I introduced myself. While making a miniscule code change I decided to improve the readability of the following line by inserting a space.

After deploying at a customer, the library soon showed a complete disregard for database transactions.
