I’m working on an iOS app using Core Data with CloudKit synchronization (NSPersistentCloudKitContainer). In my Core Data model, I have defined relationships between entities (e.g. 1:n and n:m). These relationships and constraints are clearly set up in the .xcdatamodeld file. However, after enabling CloudKit and letting the schema initialize in the iCloud container, I noticed that these constraints (relationships, cardinality, etc.) do not seem to be reflected in the CloudKit schema as I would expect. From what I can see: • The record types are created in CloudKit • Fields are present • But relationships and constraints are not represented in the same way as in Core Data This leads me to a few questions: 1. Is it expected that Core Data relationship constraints are not explicitly mirrored in the CloudKit schema? 2. How does CloudKit internally handle relationships defined in Core Data? 3. Are developers expected to enforce these co

In QMetry, I am unable to perform a DELETE request using Content-Type: application/json. However, the same API works correctly for GET and POST requests with JSON. The DELETE operation succeeds only when Content-Type is set to multipart/form-data, not with JSON. The step is I request api (API)

When instructed to append a total to the table in Excel, what action does Copilot take? It adds a sum to the top of the last column. It adds a sum to the bottom of the first column. It adds a sum to the top of the first column. It adds a sum to the bottom of the last column.

My intention is that I want the recursive bit to go down in values for the pc table and up in values for the plus_one recursive formula until the value in plus_one is greater than the one in pc and then return the plus_one value. Instead my code below enters an infinite loop. create table pc ( c integer not null ) strict; create index ipc on pc ( c desc ); insert into pc(c) values (8); insert into pc(c) values (6); insert into pc(c) values (4); insert into pc(c) values (2); insert into pc(c) values (0); with recursive meet_in_middle ( cit, plus_one ) as ( values ( 0x7FFFFFFFFFFFFFFF, 0 ) union all select pc.c as cit1, meet_in_middle.plus_one + 1 from pc, meet_in_middle where meet_in_middle.plus_one > cit1 ) select meet_in_middle.plus_one from meet_in_middle;

I am trying to process a large log file generated from a script. I would like to count the number of DMAs for each type of issues logged. Therefore I would like to reformat the log so all the lines start with the word DMA. Any ideas how I can use Regex in Notepad++ to do this? Original text: DMA: DTS030A - Subnetwork name not populated DMA: DWD019 - Subnetwork name not populated DMA: DTD012 {C9A805B2-58EF-442B-B6FC-BBF933E84AA1} Invalid subnetwork connectivity DMA: DTD012 {C5B8A4A9-410F-46CE-AE09-46EA8E11B2F4} multiple subnetwork controllers Expected output: DMA: DTS030A - Subnetwork name not populated DMA: DWD019 - Subnetwork name not populated DMA: DTD012 {C9A805B2-58EF-442B-B6FC-BBF933E84AA1} Invalid subnetwork connectivity DMA: DTD012 {C5B8A4A9-410F-46CE-AE09-46EA8E11B2F4} multiple subnetwork controllers

I am trying to download historical stock data for Microsoft (MSFT) using the yfinance library, but I am not receiving the expected data. I have already tried upgrading the library to the latest version. My Setup: Python version: 3.11.3 yfinance version: 0.2.31 Operating System: Windows 10 pro Code: # Trying again to fetch data for microsoft(MSFT) using yfinance df =yf.download("MSFT", start='2025-01-01', end='2025-02-01') df.head() The Issue: When I run the code above, I get the following result: " Failed to get ticker 'MSFT' reason: Expecting value: line 1 column 1 (char 0) [*********************100%%**********************] 1 of 1 completed 1 Failed download: ['MSFT']: Exception('%ticker%: No timezone found, symbol may be delisted') " What I've tried: Ran pip install --upgrade yfinance to ensure I'm on

​ I am using InstallShield 2020 Premier R2. ​ I got the code signing certificate from DigiCert and use its KeyLocker to do the code signing. ​ In the past, I install everything on my WIndows 7 and InstallShield can sign .mst files properly. ​ Now I want to do the same thing on my new laptop with Windows 11 system. I have installed the certificate on the local computer. And Windows SDK sigetool can sign .EXE and .DLL files properly. ​ In my InstallShield project, I select the same certificate as the one on WIndows 7 in the "Signing" tab. ​ Everything on Windows 11 seems to be same as those on Windows 7. But when I built my InstallShield project, I get the following error: Started signing 1025.mst ... SigningHelper: error 0x80092006 while attempting to sign file ISDEV : error -1027: Failed signing 1025.mst How to fix the problem?

I have a hash table with the key type std::array<uint8_t,6>, and I am trying to come up with as fast hash function as possible. One option is to pack all six 8-bit integers into a single 64-bit integer first, and then just use std::hash<uint64_t>. I've tried two different ways how to resolve this packing, one based on casting and shifting, the second one based on memcpy. uint64_t pack(std::array<uint8_t, 6> key) { return (static_cast<uint64_t>(key[0]) << 0) | (static_cast<uint64_t>(key[1]) << 8) | (static_cast<uint64_t>(key[2]) << 16) | (static_cast<uint64_t>(key[3]) << 24) | (static_cast<uint64_t>(key[4]) << 32) | (static_cast<uint64_t>(key[5]) << 40); } uint64_t pack(std::array<uint8_t, 6> key)

Here is the original problem: Design a 1-12 counter with the following inputs and outputs: Reset Synchronous active-high reset that forces the counter to 1 Enable Set high for the counter to run Clk Positive edge-triggered clock input Q[3:0] The output of the counter c_enable, c_load, c_d[3:0] Control signals going to the provided 4-bit counter, so correct operation can be verified. You have the following components available: the 4-bit binary counter (count4) below, which has Enable and synchronous parallel-load inputs (load has higher priority than enable). The count4 module is provided to you. Instantiate it in your circuit. logic gates

Title: How to implement a mutual watchdog (process pairing) in C++ on Windows without recursion? Body: I am developing a Windows console application in C++ (using MSVC) and I want to implement a mutual watchdog system. The Goal: I have two processes: MainApp.exe and Watchdog.exe. If MainApp is closed or crashes, Watchdog should restart it. If Watchdog is killed, MainApp should restart it. The Problem: Currently, I am facing a "process recursion" issue. When MainApp starts, it launches Watchdog. Then Watchdog checks for MainApp, and if it doesn't correctly identify the existing parent process, it launches a new instance of MainApp, which launches a new W
