QUESTION
I'm trying to remove an entry from the Caffeine cache manually. I have two attempts but I suspect that there are some problems with both of them:
This one seems like it could suffer from a race condition.
...ANSWER
Answered 2021-Jun-16 at 00:25You should use cache.asMap().remove(key) as you suspected. The other call delegates to this, but does not return the value because that is not idiomatic for a cache.
The Cache interface is opinionated for how one should commonly use a cache, while the asMap() view is more raw to allow for advanced operations. For example, you generally wouldn't iterate over a cache (e.g. memcached doesn't allow this), but if you need to then the Map provides that support. All calls flow into the same backing structure, so there will be no inconsistency. The APIs merely try to nudge users towards best practices, but strive to not block a developer from getting their work done safely and correctly.
QUESTION
i'm trying to use public publicRuntimeConfig inside a TypeScript plugin with no success. With JS plugins i have no problems. But now i'm really stuck, i think i don't look at the right place.
The question is how can i access to this config in a TypeScript plugin ?
Here's my nuxt.config.js:
...ANSWER
Answered 2021-Jun-15 at 20:42Nuxt makes the $config available in two ways: as this.$config on every component instance, and context.$config passed to "special nuxt lifecycle areas like asyncData, fetch, plugins, middleware and nuxtServerInit" (docs).
It looks like you need to access the $config outside a component, so you'll need to retrieve it early in the request cycle. In particular, since you're mutating the Vue.prototype, this feels like a good fit for a plugin in the Nuxt sense, which isn't quite what you've got in your code.
If you put your plugin file in the plugins directory and reference it from the plugins array in nuxt.config.js (see link above for a broader example), you could rewrite it like this to access $config:

I am having problems getting data from a element using Selenium with the line:
...ANSWER
Answered 2021-Jun-15 at 20:06When an element has spaces in the class attribute, that means it has multiple classes, so you'll need to handle that another way.
One option is with CSS selectors.

I am running some code on a STM32 chip which is logging to my uart port.
I am having a hard time finding the proper way to log an array of bytes. I wrote this function:
...ANSWER
Answered 2021-Jun-15 at 19:36If the problem did end up being from heap overuse (from strncat), then you could try out this implementation that uses the return from sprintf to append to the string as your building it.
QUESTION
I'm currently learning HTML, CSS, and JavaScipt. I'm trying to make a basic project, but I'm having problems with adding a new image on the new card. When I click on the 'add item' button, I create a new card with image. However, when I add another card for the second time, my image from the first card that I created will disappear. Can someone help me on how to fix this solution. Thank you.
...ANSWER
Answered 2021-Jun-15 at 19:05Rather than using two different function, one for adding card image and one for card content, try combining both of them.. here use the code for your reference.

Answered 2021-Jun-15 at 17:22You most likely don't want to call getData on every render, so you should store the response somewhere, it might be in the component state:

How to get the return value? Attach my code. My intention: Want to check the QListWidget and if it's empty, a message Box popup will raise and ask the option from the user. Problem: At the stage of beginning itself, a Message box popup will display, (I don't want it at the beginning stage), If the QListwidget is empty then the MessageBox popup will display as desired, and if we select "Yes" or " No" Button, Nothing will return/print in the first file. How to resolve?
Main
...ANSWER
Answered 2021-Jun-15 at 16:49In first it is not necessary to make the verification be done in a new class, it is also logical that you invoke func_create_newitem since as you point out that method must be invoked when the item was not found.

Install problems
You can use problems like any standard Python library. You will need to make sure that you have a development environment consisting of a Python distribution including header files, a compiler, pip, and git installed. Make sure that your pip, setuptools, and wheel are up to date. When using pip it is generally recommended to install packages in a virtual environment to avoid changes to the system.
