Re: Differential Directory, indexing method 6 Days 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 4 Days 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. At FixnVibe, our approach to mobile phone … Re: How to open an Excel Document in VB.NET 1 Week Ago by Pelorus_1 A Microsoft Excel document can be opened in VB.NET using the Microsoft.Office.Interop.Excel library. Using Workbooks.Open(), open the workbook, and then display the Excel window. Reference the Excel COM object in your project. Re: How to open an Excel Document in VB.NET 1 Week Ago by JamesMichaelm I see it's been a while since you posted, but I'm curious if anyone here has tried using the Open XML SDK instead of Interop or OleDb for reading Excel files. I found it faster and doesn't require Excel to be installed, though it can be more complex for writing. Wondering how others handle big Excel files or ones with tricky formatting? Re: How to open an Excel Document in VB.NET 1 Week Ago by PitSterw I've worked on something similar and found that using Microsoft.Office.Interop.Excel lets you open the file and loop through cells easily. Differential Directory, indexing method 1 Week Ago by xrjf **Features:** * Retrieves the differentiating bit of a key with respect to the previous one and stores only this position in the index. * With at most one single disk read, assuming the index is in memory, it determines whether the key exists or not. * The index is always sorted and therefore requires no reorganization. * Performance is … Re: Differential Directory, indexing method 1 Week 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 Week 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 Week 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 Week 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 Week 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."
