Posted: 11 May 2021 09:06 AM PDT I am trying to make a payment gateway with Stripe and I have more questions than solutions. I explain the business model to see if someone can help me. Company "X" has a parking APP. A user "A" can find a place to park his car and a user "B" can save the place for him. If all goes well, payment needs to be made. The "problem" with the payment is that user "A" does not pay directly to user "B" (to his Stripe account, because he does not need one?), But rather that the money goes through the company's Stripe account , the company keeps a commission and then pays user "B". What I have done so far is:
Can anyone help me? Thanks! |

Python pandas print each group from a groupby object as a single row Posted: 11 May 2021 09:06 AM PDT I am having a groupby object The data are grouped by the column "ref". It happens that many lines have the same ref, for example As you see, the second column has identical values ANN12010-RA, I would like to print each "ref" block in its own file, on a single row. Expected output from the example The order of elements is not important. The number of columns per row can vary, I don't know how many elements each group has. What's the best way to achieve this? Knowing the groupby object can be thousands of lines long. Thanks a lot |

Repeat each element of vector N times according to other vector R Posted: 11 May 2021 09:06 AM PDT I have a vector of values, in which I would like to recursively repeat each element a variable amount of N times according to another vector, using R. I know how to repeat each element exactly the same N times with repeat(x, each=N), but I cannot figure it out how to generate a variable number of repetitions. An example: Vector of values Vector of repetition Expected result I guess some kind of apply function family could work but cannot get the proper code to do it... Could anyone help? Many thanks |

C++ constructor has no object [duplicate] Posted: 11 May 2021 09:06 AM PDT I just learned about the constructor, and there is a question I am not sure, whether Person(10) is actually Person px(10), and then p2 = px. But the printed result is "paramererized constructor!" and "Destructor!" ", there is no "Copy Constructor!". Is the system automatically optimized or I made a mistake? |
Java spring boot profiles in multiple properties files Posted: 11 May 2021 09:05 AM PDT Is it possible to use profiles with multiple properties files in spring boot? I have some modules, call it "moduleA" and "api" All modules have own properties files api (just a library)
moduleA (contains main method)
Loading the api.properties file in moduleA works fine. Also loading the profile prod in moduleA works fine. But it loads just the content of application-prod.properties. From the api module always the "normal" api.properties is loaded. api-prod is ignored. |

Why there is a problem if there is an empty stack (java) Posted: 11 May 2021 09:06 AM PDT (leetCode #20) Coding Question : Given a string s containing just the characters '(', ')', '{', '}', '[' and ']', determine if the input string is valid. An input string is valid if:
Now here is the answer to this coding question. I am a bit confused that what is the purpose of the "!stack.isEmpty()"? If I erase them, and put "]" for it put, it throws an runtime error which said "java.util.EmptyStackException". Can anyone clarify this? I learned the stack today, so I am bit confused. |

Amazon Pay Sandbox Error when trying to login on localhost - "Scheme not HTTPS" Posted: 11 May 2021 09:06 AM PDT I am trying to integrate Amazon Pay for a web shop. The login button is displayed correctly but as soon as I login with my sandbox account credentials to show the address widget I get the following error in my Chrome dev tools console: [Amazon.error] attempted redirect to http://myownvirtualhost.local/shop.html?... but scheme is not HTTPS. So the error is obvious but how do I fix this? After login the redirect is supposed to happen on a HTTPS url but as already mentioned I am developing on my localhost with a configured virtual host. I also use the correct (EU) sandbox Widget.js file and set sandbox mode to true in my PHP configuration. My code: I didn't provide my merchant id as this is an example. So my redirect url has HTTP as scheme and this is the cause of the error. I am confused because after reading the registration chapter of the Amazon Pay Integration guide I thought SSL is not relevant on localhost. From the integration guide:
Any help is appreciated. Thanks in advance! |

Understanding a table bloat query Posted: 11 May 2021 09:05 AM PDT When researching table bloat there is this query that crops up in quite a few places. From what i can see its basically been copy pasted since 2008 I'm struggling to decipher this query so as not to blindly rely on it. What is so special about the 27 or 23 here and the difference between a windows and non-windows install to offer the values 4 or 8 ?
Can anyone offer any insights into this query ? Would using pgstattuple be a more sensible approach to calculating table bloat ? Thanks. |
