I got the following problem. When user register he will be on a page, where I show a message like check your Email account. And when user check his account and confirm his mail he automatically get to homepage. So far so good. But when user press register button an get mail and reload the page he get also inside homepage without confirm his mail. I trie this

How should I rewrite the following code idiomatically?

The problem seems to be that traversal could be modified during action(). One solution would be to create a temporary copy of traversal inside of traverse, but that would be a burden if traversal is large.

Maybe Idiomatically access an element of a vector mutably and immutably is the canonical version of this, but I am not sure (and have not fully understood the referenced issue)?

I have tried to upload multiple images through multi_image_picker depedency and using multipart request, where I upload images on first screen and get them on another screen and tried to post them through API, instead gets an error in LogCat as below:

Before switching to Flutter 2, I was using an old version of SharedPreferences without problems, and now I have the latest version.I was able to store values of type int in a separate class that I use from all aspects of the application, but after moving and updating all attempts to save the values, I have the following problem:

I have a class A like this:

Background & Problem

I am trying to web scrape links to articles from a news webpage. I've done a nested find_all and I've managed to get the 'a href' sections, but this also includes info I don't require like article name.

What I need Help with

I've searched several articles on SO such as this. But none seem to work for my specific case. Does Anyone know how I can create a list of just news article links?

My code so far

so I tried to link 2 screens in flutter together via a Textbutton but it won't work.

This is my code for my Text Button :

I'm trying to install the code from this git-repo for a university project and I'm stuck because ld does not seem to be able to link lua properly. I followed the install instructions and compile the code with:

The python interpreter segfaults when running in a miniconda environment on a fresh install of ubuntu 20.04.2. This seems to happen intermittently, both while running "pip" during the conda setup of an environment and during the execution of code like below.

The segfault always occurs when running the following code, which reads texts from files and tokenizes the result. The segfault location changes from run to run. Also the exact same code can run on another computer with the same conda environment on a ubuntu 18.04.

The core dumps always points to some function in the unicodeobject.c file in python but the exact function changes from crash to crash. At least one crash has a clear dereferenced pointer 0x0 where the "unicode object" should be.

My guess is that something causes the python interpreter to throw away the pointed to unicode object while it is still being worked on causing a segfault. But any bug in the interpreter or NLTK should have been noticed by more users, and I cannot find anyone with similar issues.

Things tried that didn't fix the issue:

1. Reformatting and reinstalling ubuntu
2. Switched to ubuntu 18.04 (on this computer, another computer with 18.04 can run the code just fine)
3. Replacing hardware, to ensure that RAM, or SSD disk isn't broken
4. Changing to python versions 3.8.6, 3.8.8, 3.9.2
5. Cloning the conda environment from a working computer to the broken one

Attached is one stacktrace of the fault handler along with it's corresponding core dump stack trace from gdb.
