I am writing a model Series class (kinda like the one in pandas) - and it should be both Positional and Associative.

QUESTION
Below is the code. I understand applicative, functor, traversable and monad to a certain extent. The iterator and yield types, and yield functions are what I struggle understanding the most. For example, what are i o r in Iterator and i o r a in Yield? what does traverseY do exactly and what do the signatures mean? and How Monad Cont is applied here also confuses me a lot. Thank you for reading, any input would be appreciated.

QUESTION
I'm trying to initiate a Springboot project using Open Jdk 15, Springboot 2.6.0, Springfox 3. We are working on a project that replaced Netty as the webserver and used Jetty instead because we do not need a non-blocking environment.
In the code we depend primarily on Reactor API (Flux, Mono), so we can not remove org.springframework.boot:spring-boot-starter-webflux dependencies.
I replicated the problem that we have in a new project.: https://github.com/jvacaq/spring-fox.
I figured out that these lines in our build.gradle file are the origin of the problem.
...ANSWER
Answered 2022-Feb-08 at 12:36This problem's caused by a bug in Springfox. It's making an assumption about how Spring MVC is set up that doesn't always hold true. Specifically, it's assuming that MVC's path matching will use the Ant-based path matcher and not the PathPattern-based matcher. PathPattern-based matching has been an option for some time now and is the default as of Spring Boot 2.6.
As described in Spring Boot 2.6's release notes, you can restore the configuration that Springfox assumes will be used by setting spring.mvc.pathmatch.matching-strategy to ant-path-matcher in your application.properties file. Note that this will only work if you are not using Spring Boot's Actuator. The Actuator always uses PathPattern-based parsing, irrespective of the configured matching-strategy. A change to Springfox will be required if you want to use it with the Actuator in Spring Boot 2.6 and later.
QUESTION
I'd like to provide a view for a customer data structure, with it's own iterator. I wrote a small program to test it out, shown below. It I uncomment begin(), then it works. But if I use DummyIter, then I get a compile error.
In my full program, I've implemented a full iterator but for simplicity, I narrowed it down to the necessary functions here.
...ANSWER
Answered 2022-Mar-18 at 11:01This can't work since return types of your begin and end do not match.
So basically those iterators can't be compared to each other.
Prove:
- here is your code with extra static assert
- here is dummy fix which compiles since now same return type is used for
beginandend
Minimum requirement is that result of begin() and end() are comparable. Different types for begin() and end() are useful when size of range is not known. Here is nice explanation of sentinel (mentioned in comment).
QUESTION
I am working on a spatial search case for spheres in which I want to find connected spheres. For this aim, I searched around each sphere for spheres that centers are in a (maximum sphere diameter) distance from the searching sphere’s center. At first, I tried to use scipy related methods to do so, but scipy method takes longer times comparing to equivalent numpy method. For scipy, I have determined the number of K-nearest spheres firstly and then find them by cKDTree.query, which lead to more time consumption. However, it is slower than numpy method even by omitting the first step with a constant value (it is not good to omit the first step in this case). It is contrary to my expectations about scipy spatial searching speed. So, I tried to use some list-loops instead some numpy lines for speeding up using numba prange. Numba run the code a little faster, but I believe that this code can be optimized for better performances, perhaps by vectorization, using other alternative numpy modules or using numba in another way. I have used iteration on all spheres due to prevent probable memory leaks and …, where number of spheres are high.

QUESTION
Springfox 3.0.0 is not working with Spring Boot 2.6.0, after upgrading I am getting the following error
...ANSWER
Answered 2021-Dec-01 at 02:17I know this does not solve your problem directly, but consider moving to springdoc which most recent release supports Spring Boot 2.6.0. Springfox is so buggy at this point that is a pain to use. I've moved to springdoc 2 years ago because of its Spring WebFlux support and I am very happy about it. Additionally, it also supports Kotlin Coroutines, which I am not sure Springfox does.
If you decide to migrate, springdoc even has a migration guide.
QUESTION
Say I have a custom container class that stores data in a map:
...ANSWER
Answered 2022-Jan-31 at 08:18Are view iterators valid beyond the lifetime of the view?
The property here is called a borrowed range. If a range is a borrowed range, then its iterators are still valid even if a range is destroyed. R&, if R is a range, is the most trivial kind of borrowed range - since it's not the lifetime of the reference that the iterators would be tied into. There are several other familiar borrowed ranges - like span and string_view.
Some range adaptors are conditionally borrowed (P2017). That is, they don't add any additional state on top of the range they are adapting -- so the adapted range can be borrowed if the underlying range is (or underlying ranges are). For instance, views::reverse(r) is borrowed whenever r is borrowed. But views::split(r, pat) isn't conditionally borrowed - because the pattern is stored in the adaptor itself rather than in the iterators (hypothetically, it could also be stored in the iterators, at a cost).
views::values(r) is an example of such: it is a borrowed range whenever r is borrowed. And, in your example, the underlying range is a ref_view, which is itself always borrowed (by the same principle that R& is always borrowed).
Note that here:
QUESTION
I use std::erase_if to erase half the elements from containers using a captured counter as follows. C++20 compiled with gcc10
ANSWER
Answered 2021-Dec-28 at 07:50remove_if takes a Predicate. And the standard library requires that a Predicate type:
Given a glvalue
uof type (possibly const)Tthat designates the same object as*first,pred(u)shall be a valid expression that is equal topred(*first).
Your predicate changes its internal state. As such, calling it twice with the same element will yield different results. That means it does not fulfill the requirements of Predicate.
And therefore, undefined behavior ensues.
