            InputStreamReader and BufferedReader are so-called filter streams: They don't themselves represent a resource that must be closed; they wrap around some other resource.

            The rule is, if you close a filterstream, it closes the thing they wrapped. (So, calling close() on br will cause that bufferedreader to invoke close() on that new InputStreamReader object, which in turn causes it to call close on System.in.

            Here's the thing, while usually you want to always close resources, you do not want to close System.in!

            You are, here, by using the try construct.

            Solution: Just.. do not do that. Do not make a try() {} block here.

            Your IDE might complain. Tell it to shut up, it is wrong.

            You get this error because the code closes System.in (by reaching the end of the try-with-resources block, which invokes close() on the resource, which invokes close() on the ISR, which invokes close() on System.in), and once it is closed, no further lines can be read from it.

            Regex matching issue to Test-String
            Asked 2021-Jun-03 at 18:52

            i have a problem and dont get it.

            My Regex:

            My Test-String:

            I have two issues and one general question :)

            1. As you can see in my Test-String the very last (german) Phone Number (the big yellow one in the Test-String attachment) does not match my Regex-Pattern correctly. I dont get it, what is the Problem here? the "0049" fits Group 5, but should fit Group 2, why is that?

            2. My second Problem is, how can i get rid of the spaces before and after every match? (The 7 yellow small circles in the Test-String Attachment)

            For copy/paste purposes, here is the Regex and Test-String again:

            Regex: ((\+\d{2}|00\d{2})?([ ])?(\()?(\d{2,4})(\))?([-| |/])?(\d{3,})([ ])?(\d+)?([ ])?(\d+)?)

            Test-String: Vorwahl 089, die E.123 ebenfalls , also (089) 1234567. Die DIN 5008, also +49 89 1234567 respectivly 0049 89 1234567. Die E.123 empfiehlt, also +49 89 123456 0 respectivly 0049 89 123456 0 oder +49 89 123456 789. Also +49 89 123 456 789. Klammern 089/1234567 und 0151 19406041. Test +49 151 123 456 789 respectivly 0049 151 123 456 789

            Last but not at least, my general question: Is it a good approach to Group each logical part as i did in my example?

            A last Information: I validate my Regex with https://regex101.com/ and use it in Python with the re Module.

            The thing that makes it unpredictable are the numerous optional groups (..)?.

            As first step i recommend replacing ([ ])?(\d+)? as a coupled expression ([ ]?\d+)?, which will avoid spaces at the end of the match - your point #2.

            As a second step i recommend coupling the first optional space with the expression of the "national dialling": ((\+|00)\d{2}([ ])?)?. Now we are lucky, because it solves both the space at the beginning and the recognition of the whole number, due to less possible matching options.

            The new expression now looks like this:

            WordPress/WooCommerce: Save custom payment post meta
            Asked 2021-Jun-02 at 17:44

            I am using a plugin that is creating a custom payment type where the user can fill in a custom payment ID. The thing is, I want that custom payment ID stored in an ACF field as post meta on the WooCommerce order edit page. I have created an ACF field named 'kkpayment' for this task.

Am I missing something obvious?

            Because all of your returns are in the while loop. From msdn: msdn

            • The while statement: conditionally executes its body zero or more times.

            Meaning that is not guaranteed that the code inside the while loop will be executed at all. It might just skip the whole, but no returns after it, that's why you are getting an error: "Not all code paths return a value", although multiple paths returns a value, NOT all path.

            You specified that the mattaVag variable is true at the beginning but the compiler doesn't know it. If this loop will be executed at least one time anyway, change it to do...while. Or place the return b; outside your loop

            So what you did wrong is, that you want to use readdirSync before you included the fs library in your code. Just move the require statement over the readdirSync and it should work:

            Rules for memory allocation.

            • Do not allocate so much RAM that swapping will occur. Swapping is terrible for MySQL/MariaDB performance.
            • Do adjust innodb_buffer_pool_size such that most of RAM is in use during normal time and even for spikes in activity. (I often say "set it to 70% of available RAM", but you are asking for more details.)
            • Do not bother changing other settings; they add to the complexity of "getting it right".

            There are 3 situations (based on innodb_buffer_pool_size and dataset size):

            • Tiny dataset -- buffer_pool is bigger than necessary --> wasting some of RAM, but so what; it is not useful for anything else. And it give you some room for growth.
            • Medium-sized dataset -- Most activity is done in RAM; the system will run nicely.
            • Big dataset -- The system may be I/O-bound. Adding RAM is a costly and brute force solution. However, some software techniques (eg, better indexes) may help, such as this for WordPress and WooCommerce.

            I fixed it with a little help elsewhere. Seems I firstly forgot to import Reactive Forms, as I only had Forms imported.

            Then I had some issues in regards to formData.append. I found a better solution to the coding I had done in that part and it works good. I also had some issue where I could not use response["result"]. But also found the solution for that with (response: any) => I don't know if I had typed something wrong on the form part, but it works now after copying something from StackBlitz.

            How to write multiple lines to file in C++ without losing previous lines
            Asked 2021-May-18 at 08:10

            I need to write multiple lines in a txt and binary file and I created a function (I'll attach it below) that's supposed to write a few array items into the file. The problem is, I used fprintf while I open and close the file in the same function and so every time my for (because it's an array) calls the function, it overwrites the file. I'm thinking of opening the file and closing it before and after the for, respectively. Is there a more elegant way of doing what I'm after? Currently I'm using File I/O for consulting purposes and it only mentions fprintf.
