At… Re: Data storage and retrieval - cache or database 2 Days Ago by jonathannweyer If the "status" doesn't change frequently, caching is a solid option. You could fetch it from the database the first time it's needed, then store it in a cache (like in-memory or Redis, depending on your setup), and use that for subsequent loads. Re: Differential Directory, indexing method 4 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: Segmentation Fault in C++ Program – Need Debugging 3 Weeks Ago by rproffitt Thanks for the MVE (minimum viable example). But it's just bad code. c, c++ and a lot of language won't stop you from going out of bounds. Re: Segmentation Fault in C++ Program – Need Debugging 3 Weeks Ago by Dani You’re creating an array of 5 integers and then trying to access the 11th integer in the array (assuming the indexes start at 0). You’re getting an out of bounds error because you’re trying to access an array element that doesn’t exist. You can access arr[0] up through arr[4]. Re: Segmentation Fault in C++ Program – Need Debugging 3 Weeks Ago by Salem It should be obvious by now from their posting history that the OP is a troll. Re: Optimizing working with big data 2 Weeks Ago by Salem My first thoughts would be 1. What is large? Are we in the TB range or mere handfuls of GB? 2. How often do you need to do this? Is it once a day, once a month, or just once. Re: Optimizing working with big data 2 Weeks Ago by Dani > What is large? Are we in the TB range or mere handfuls of GB? For the sake of argument, let's use my use case and say dozens of gigs and millions of rows. > How often do you need to do this? Is it once a day, once a month, or just once. For me, the most important is real-time read and write performance to tables with millions of … 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."

Finally, I found a solution via the [FireworksAI](https://fireworks… Re: Why my iPhone runs so slow recently? 2 Months Ago by Dani I think you're referring to physical memory (hard drive space) and not random access memory (RAM). Using up all your hdd space can make your phone go slower. RAM is transient and is just the memory the apps you currently have open at the time are using. The amount of RAM you use goes down when you close out of apps or restart your phone. Re: How to Efficiently Develop Apps for iOS and Android? 2 Months Ago by Reverend Jim … a particular occasion.
