I encounter a strange behaviour in my Spring-Boot project (v4.0.6):When I execute a Controller which retus ResponseEntity<StraingResponseBody> for writing NDJSON-Lines the FilterChainProxy of SpringSecurity will get invoked twice. In the second invocation it looses the previous resolved Authentication object and throws an error.The Controller is defined as such:@RestController public class AsyncController { private Logger logger = LoggerFactory.getLogger(AsyncController.class); ...

I have a Docker container with OrbStack that contains a directory repos with a repository app-main and worktrees like app-feature-a to develop in parallel. Configuration is done in order to prevent modification of the container configuration file in the ruing Docker. project/ ├── .devcontainer/ # outside the mount, on purpose │ └── devcontainer.json └── repos/ ├── app-main/ ├── app-feature-a/ └── app-feature-b/ MWE for devcontainer.json : { "name": "myproject", "image": ...

We would like to use Hibeate StatelessSession injected into our Spring Data JPA repositories. Our understanding is this requires HibeateTransactionManager and SharedSessionCreator.createSharedStatelessSession. Our setup is like follows: @Bean public HibeateTransactionManager transactionManager(EntityManagerFactory entityManagerFactory) { var hibeateTransactionManager = new HibeateTransactionManager(entityManagerFactory.unwrap(SessionFactory.class)); retu hiber...

I created a file with one line "bug line", initialized git repository and committed change. Then I added the second line "staged" and staged the change. Then I added the third line "unstaged". How to add a commit changing the first line to "bug line changed" so that I still get the second line as staged change and the third line as unstaged change without merge conflicts?...

I was reading a (quite old) book on POSIX API, and in the chapter on threads it says that on retu from main() all the threads (including detached ones) are terminated. I would expect that std::thread::detach() inteally uses POSIX threads API, and yet it seems that a detached std::thread is sort of joined with the main() thread (or the main process really), after the main() function retus on Ubuntu 26.04. For example, the code below blocks on a read from std::cin and, if I write anything ...

The following code snipped defines a nested chain of templated C++ classes. The problem I have starts on the third level. The initialization of the three level nested class works well, which can easily checked in a debugger. However, a problem arises when attempting to access the nested class member variables aValue. While the first two levels work well, accessing third level aValue gives me no joy. Any suggestions on how to propagate variable access down the chain? Ideally, is there any iterato...

I'm working on a Laravel project and I need to search through 2 models as the same time. I decided to use a union for this query, as I would do it in SQL. One of my models is converted into the other, and then the two queries are unioned. I was expecting to be able to filter as well after that, but any where clause I'm using ends up applying only on the first part of the union, and not the second. Here's the code EntityMember::union( User::select(*convert User into something similar to Entit...

I am having trouble compiling a C program that uses a shared library. To reduce the problem as much as possible, I am following a tutorialI have two source files, in the same directoryfoo.c:#include <stdio.h> exte void foo(void); void foo(void) {     puts("Hello, I am a shared library"); } main.c:#include <stdio.h> int main(void) {     puts("This is a shared library test...");     foo();     retu 0; } foo.c compiles to a shared library:gcc -c -Wall -Werror -fpic foo.c g...

When working with keyboard input in a situation like the one shown in the next simplified example: // abc.hpp #pragma once #include <array> // ranges of integer values in the enum could be contiguous or // not, so question is for a general scenario. However if being // a contiguous range of integer values makes things notably // simpler, then certainly it'd be interesting to know about it. enum FileType : int { JSON = 1, YAML = 2, XML = 3 }; constexpr std::array<FileType, 3>...

I'm leaing Python and using VS Code (Windows). I wanted to clear the terminal from the long paths when ruing code, so I installed Code Ruer and went to Settings -> Executor Map, and changed python map from "python -u" to "clear && python3 -u". But when I run code, I get what's in the picture instead of execution result. (There's nothing in output console either.) ...

I am working on improving the SEOP of an e-shop built as a React SPA. (I know its bad). The e-shop contains products that have one main Manufacturer Part Number, but some products can also have one or more alteative manufacturer part numbers. I need to make sure that wehn people search on Google using one of these alteative part numbers, Google can associate the alteative number with the correct product and show the corresponding product page in the search results. For example, if a produc...

I'm trying to lea graphics programming. Currently, I'm trying to make my camera look at the world origin at (0, 0, 0), but I can't understand why this operation is inverted for the camera. For example, if I have a camera at (0, 0, -5), it tries to look at (0, 5, 0). Instead of looking at the desired position, the camera looks at the inverted position at (0, -5, 0).Here's the code implementation for the context:...

When conditional branching logic grows large in Python, the advice has always been to map keys to functions or values using a dictionary lookup mapping.get(key) to achieve O(1) time complexity, rather than using a long, O(n) sequence of if-elif statements. However, with structural patte matching (match-case) in Python 3.10+, the syntax looks pretty clean for these types of large branch choices: match status_code: case 200: retu "OK" case 404: retu "Not Found" case 500: retu "...
