Now that type parameters are available on golang/go:master, I decided to give it a try. It seems that I'm running into a limitation I could not find in the Type Parameters Proposal. (Or I must have missed it).

I want to write a function which returns a slice of values of a generic type with the constraint of an interface type. If the passed type is an implementation with a pointer receiver, how can we instantiate it?

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.

I was wondering if there was an easy solution to the the following problem. The problem here is that I want to keep every element occurring inside this list after the initial condition is true. The condition here being that I want to remove everything before the condition that a value is greater than 18 is true, but keep everything after. Example

Input:

I'm playing around with go generics by modifying a library I created for working with slices. I have a Difference function which accepts slices and returns a list of unique elements only found in one of the slices.

I modified the function to use generics and I'm trying to write unit tests with different types (e.g. strings and ints) but am having trouble with the union type. Here's what I have, now:

I'm developing an API with Spring Boot and currently, I'm thinking about how to handle error messages in an easily internationalizable way. My goals are as follows:

1. Define error messages in resource files/bundles
2. Connect constraint annotation with error messages (e.g., @Length) in a declarative fashion
3. Error messages contain placeholders, such as {min}, that are replaced by the corresponding value from the annotation, if available, e.g., @Length(min = 5, message = msg) would result in something like msg.replace("{min}", annotation.min()).replace("{max}", annotation.max()).
4. The JSON property path is also available as a placeholder and automatically inserted into the error message when a validation error occurs.
5. A solution outside of an error handler is preferred, i.e., when the exceptions arrive in the error handler, they already contain the desired error messages.
6. Error messages from a resource bundle are automatically registered as constants in Java.

Currently, I customized the methodArgumentNotValidHandler of my error handler class to read ObjectErrors from e.getBindingResult().getAllErrors() and then try to extract their arguments and error codes to decide which error message to choose from my resource bundle and format it accordingly. A rough sketch of my code looks as follows:

Input:

(Note! This question particularly covers the state of C++14, before the introduction of inline variables in C++17)

• What constitutes odr-use of a constexpr variable used in the definition of an inline function, such that multiple definitions of the function violates [basic.def.odr]/6?

(... likely [basic.def.odr]/3; but could this silently introduce UB in a program as soon as, say, the address of such a constexpr variable is taken in the context of the inline function's definition?)

TLDR example: does a program where doMath() defined as follows:

I have a nested list of lists which contains some data frames. However, the data frames can appear at any level in the list. What I want to end up with is a flat list, i.e. just one level, where each element is only the data frames, with all other things discarded.

I have come up with a solution for this, but it looks very clunky and I am sure there ought to be a more elegant solution.

Importantly, I'm looking for something in base R, that can extract data frames at any level inside the nested list. I have tried unlist() and dabbled with rapply() but somehow not found a satisfying solution.

Example code follows: an example list, what I am actually trying to achieve, and my own solution which I am not very happy with. Thanks for any help!

I've got a docker image running 8.0 and want to upgrade to 8.1. I have updated the image to run with PHP 8.1 and want to update the dependencies in it.

The new image derives from php:8.1.1-fpm-alpine3.15

I've updated the composer.json and changed require.php to ^8.1 but ran into the following message when running composer upgrade:

In this programming problem, the input is an n×m integer matrix. Typically, n≈ 10⁵ and m ≈ 10. The official solution (1606D, Tutorial) is quite imperative: it involves some matrix manipulation, precomputation and aggregation. For fun, I took it as an STUArray implementation exercise.

I have managed to implement it using STUArray, but still the program takes way more memory than permitted (256MB). Even when run locally, the maximum resident set size is >400 MB. On profiling, reading from stdin seems to be dominating the memory footprint:

Functions readv and readv.readInt, responsible for parsing integers and saving them into a 2D list, are taking around 50-70 MB, as opposed to around 16 MB = (10⁶ integers) × (8 bytes per integer + 8 bytes per link).

Is there a hope I can get the total memory below 256 MB? I'm already using Text package for input. Maybe I should avoid lists altogether and directly read integers from stdin to the array. How can we do that? Or, is the issue elsewhere?
