| Pay with Stripe 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: - Create a Connected account (trial mode)
- Create a PaymentIntent in which I put the "Amount", the "ApplicationFeeAmount" and the TransferData [Destination] of the recipient's connected account. I send the "Amount" to the company's Stripe account, subtract the "ApplicationFeeAmount" and send the money to the connected account of user "B" (which is then automatically or manually sent to his bank / card account) The "problem" I see with this is that when using connected accounts, the money is sent directly to the bank or debit card and I cannot use it, for example, to pay with Stripe balance.
Can anyone help me? Thanks!  |

I would like to identify the start and end of the weekly measurements and group them as follow. If there is no gap between the start and end day then: a.) 1 day (start=end); b.) 2 days; c.) 3 days; d.) 4 days; e.) 5 days; f.) 6 days and g.) 7 days.

| 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 ref query_x query_y ANN00118-RA Charonia_GIQZ01011680.1.p1 Typhlosyrinx_Contig7942.p1 ANN00127-RA Charonia_GIQZ01023156.1.p1 Typhlosyrinx_Contig11188.p1 ANN00130-RA Charonia_GIQZ01000168.1.p1 Typhlosyrinx_Contig15281.p1
The data are grouped by the column "ref". It happens that many lines have the same ref, for example test.get_group('ANN12010-RA') query_x ref query_y 0 Charonia_GIQZ01000001.1.p1 ANN12010-RA Typhlosyrinx_Contig13935.p1 1 Charonia_GIQZ01000001.1.p1 ANN12010-RA Typhlosyrinx_Contig13936.p1 2 Charonia_GIQZ01000001.1.p1 ANN12010-RA Typhlosyrinx_TRINITY_DN17744_c0_g2_i1.p1 3 Charonia_GIQZ01000001.1.p1 ANN12010-RA Typhlosyrinx_TRINITY_DN18267_c0_g1_i1.p2
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 ANN12010-RA Charonia_GIQZ01000001.1.p1 Typhlosyrinx_Contig13935.p1 Charonia_GIQZ01000001.1.p1 Typhlosyrinx_Contig13936.p1 Charonia_GIQZ01000001.1.p1 Typhlosyrinx_TRINITY_DN17744_c0_g2_i1.p1 Charonia_GIQZ01000001.1.p1 Typhlosyrinx_TRINITY_DN18267_c0_g1_i1.p2
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 0.5, 0.3, 0.2, 0.3, 0.1, 0.5, 0.1, 0.7 ....
Vector of repetition 2, 2, 3, 4, 3, 1, 5, 4 ....
Expected result 0.5, 0.5, 0.3, 0.3, 0.2, 0.2, 0.2, 0.3, 0.3, 0.3, 0.3, 0.1, 0.1, 0.1, 0.5, 0.1, 0.1, 0.1, 0.1, 0.1, 0.7, 0.7, 0.7, 0.7 ....
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? class Person { public: Person() { cout << "default constructor!" << endl; } Person(int a) { age = a; cout << "paramererized constructor!" << endl; } Person(const Person& p) { age = p.age; cout << "Copy Constructor!" << endl; } ~Person() { cout << "Destructor!" << endl; } public: int age; }; int main() { Person p2 = Person(10); return 0; }

| 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) - api.properties
- api-dev.properties
- api-prod.properties
moduleA (contains main method) - application.properties. <- here is profiles.active set, for example to "prod"
- application-test.properties
- application-prod.properties
- moduleA.properties
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: - Open brackets must be closed by the same type of brackets.
- Open brackets must be closed in the correct order.
Now here is the answer to this coding question. class Solution { public boolean isValid(String s) { Stack <Character> stack = new Stack <Character>(); for (char c: s.toCharArray()) { if (c == '(' || c == '{' || c == '[') { stack.push(c); } else if (c == ')' && !stack.isEmpty() && stack.peek() == '(') { stack.pop(); } else if (c == '}' && !stack.isEmpty() && stack.peek() == '{') { stack.pop(); } else if (c == ']' && !stack.isEmpty() && stack.peek() == '[') { stack.pop(); } else return false; } return stack.isEmpty(); } }
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: OffAmazonPayments.Button('amazonPayButton', 'MERCHANT-ID', { type: 'PwA', language: 'de-DE', authorization: function() { loginOptions = {scope: 'profile postal_code payments:widget payments:shipping_address', popup: true }; authRequest = amazon.Login.authorize(loginOptions, 'http://myownvirtualhost.local/shop.html?action=cart'); }, onError: function (error) { console.log('auth request: ' + error.getErrorCode() + ': ' + error.getErrorMessage()); } });
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: Obtain an SSL certificate. Your server is required to have a valid SSL certificate issued by a trusted Certificate Authority. Note: When working in a "localhost" environment, an SSL certificate is not required. For more information, see SSL certification. Any help is appreciated. Thanks in advance!  |

| How check if previous element having active class on click event Posted: 11 May 2021 09:06 AM PDT Considering the below case - I try to check on click event of <button> if there was any active class present on its parent <li> item. e.g If the user clicks on button 5, will search and check if the previous <li> has an active class or not, in that case, it will return TRUE. Same if the user clicks on button 2, will search on the all previous <li> and if not having 'active' class then it will return FALSE. <ul class="list-item"> <li><button>1</button></li> <li><button>2</button></li> <li class="active"><button>3</button></li> <li><button>4</button></li> <li><button>5</button></li> <li><button>6</button></li> <li><button>7</button></li> </ul> const listItem = document.querySelector('.list-item'); if(listItem){ const alldots = document.querySelectorAll('button'); alldots.forEach((button) => { button.addEventListener('click', (event) => { // How to check here // If there was 'active' class on previous 'li' items on 'click'? // }, false); }); }

| How to combine multiple vectors such that elements of each vector are distributed as equally as possible? Posted: 11 May 2021 09:06 AM PDT Let's say I have two or more vectors with to or more elements (single factor) each, e.g. v1 = c("a", "a", "a") v2 = c("b", "b")
What I want to do is to merge all vectors and distribute the elements for each group as equally as possible. For the simple example above there would be a single solution: c("a", "b", "a", "b", "a")
If v1 = c("a", "a", "a", "a") any of these c("a", "b", "a", "b", "a", "a") c("a", "b", "a", "a", "b", "a") c("a", "a", "b", "a", "b", "a")
would be the best solution. Is there a built-in function that can do this? Any ideas how to implement it?  |
| 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 ? CASE WHEN SUBSTRING(v,12,3) IN ('8.0','8.1','8.2') THEN 27 ELSE 23 END AS hdr,
CASE WHEN v ~ 'mingw32' THEN 8 ELSE 4 END AS ma Can anyone offer any insights into this query ? Would using pgstattuple be a more sensible approach to calculating table bloat ? Thanks. SELECT tablename AS relname, schemaname, (ROUND((CASE WHEN otta=0 THEN 0.0 ELSE sml.relpages::FLOAT/otta END)::NUMERIC,1))::BIGINT AS tbloat, (CASE WHEN relpages < otta THEN 0 ELSE bs*(sml.relpages-otta)::BIGINT END)::BIGINT AS wastedbytes FROM ( SELECT schemaname, tablename, cc.reltuples, cc.relpages, bs, CEIL((cc.reltuples*((datahdr+ma- (CASE WHEN datahdr%ma=0 THEN ma ELSE datahdr%ma END))+nullhdr2+4))/(bs-20::FLOAT)) AS otta FROM ( SELECT ma,bs,schemaname,tablename, (datawidth+(hdr+ma-(CASE WHEN hdr%ma=0 THEN ma ELSE hdr%ma END)))::NUMERIC AS datahdr, (maxfracsum*(nullhdr+ma-(CASE WHEN nullhdr%ma=0 THEN ma ELSE nullhdr%ma END))) AS nullhdr2 FROM ( SELECT schemaname, tablename, hdr, ma, bs, SUM((1-null_frac)*avg_width) AS datawidth, MAX(null_frac) AS maxfracsum, hdr+( SELECT 1+COUNT(*)/8 FROM pg_stats s2 WHERE null_frac<>0 AND s2.schemaname = s.schemaname AND s2.tablename = s.tablename ) AS nullhdr FROM pg_stats s, ( SELECT (SELECT current_setting('block_size')::NUMERIC) AS bs, CASE WHEN SUBSTRING(v,12,3) IN ('8.0','8.1','8.2') THEN 27 ELSE 23 END AS hdr, CASE WHEN v ~ 'mingw32' THEN 8 ELSE 4 END AS ma FROM (SELECT version() AS v) AS foo ) AS constants GROUP BY 1,2,3,4,5 ) AS foo ) AS rs JOIN pg_class cc ON cc.relname = rs.tablename JOIN pg_namespace nn ON cc.relnamespace = nn.oid AND nn.nspname = rs.schemaname AND nn.nspname <> 'information_schema' ) AS sml WHERE schemaname != 'pg_catalog' order by 4 desc

| Display date/time remaining current time Posted: 11 May 2021 09:05 AM PDT I am trying to create a function to send me back a String which represent a restaurant opening status like: "Open", "Closed", "22min" I have the closing time displayed as: 2021-05-11T06:45:00Z I would like to make a comparison based on current time, but it's not working. I have done the code below: fun getCloseTime(ctx: Context): String? { val timeFormatter: DateTimeFormatter = DateTimeFormatter.ofPattern("hh:mm a", Locale.ENGLISH) val diff: Duration = Duration.between( LocalTime.parse(next_close_time, timeFormatter), LocalTime.parse(getISO8601StringForDate(), timeFormatter)) return when { (diff.toDays().toInt() > 0 ) || (diff.toHours() > 0) -> "Open" (diff.toMinutes().toInt() <= 60) -> diff.toMinutes().toString() else -> ctx.getString(R.string.closed) } } private fun getISO8601StringForDate(): String? { val now = Date() val dateFormat: DateFormat = SimpleDateFormat("yyyy-MM-dd'T'HH:mm:ss'Z'", Locale.US) dateFormat.setTimeZone(TimeZone.getTimeZone("UTC")) return dateFormat.format(now) }
My goal is to: - return "Closed" when current is after the
next_close_time - when the diff between
next_close_time and current is more than an hour, we display "Open" -
- when the diff between
next_close_time and current is less than an hour, we display the remain time in minute before closure Any idea?  |
| 12 Months rolling for order amount, customer count and order count Posted: 11 May 2021 09:05 AM PDT I have 3 fields customer id, order id and order total from transactions table. Now I want to calculate 12 monthing for order amount, distinct customer count and distinct orderid count. I tried with below query : with Month AS ( select Order_date, count(distinct customerid) as distinctCustomerCount, sum(orderamount) as orderamount, count(distinct orderid) as distinctOrderCount from trans where Date(date) between Date_ADD('Day', -2, Date_ADD('Year', -2, current_date) ) and Date_ADD('Day', -2, Current_Date) group by 1 ) select a.* from ( select distinct Order_date, sum(orderamount) OVER( ORDER BY Order_date RANGE BETWEEN INTERVAL '12' MONTH PRECEDING AND CURRENT ROW) as Rolling12monthamount, sum(distinctCustomerCount) OVER( ORDER BY Order_date RANGE BETWEEN INTERVAL '12' MONTH PRECEDING AND CURRENT ROW) as Rolling12monthCustomerCount, sum(distinctOrderCount) OVER( ORDER BY Order_date RANGE BETWEEN INTERVAL '12' MONTH PRECEDING AND CURRENT ROW) as Rolling12monthOrderCount from CTEMonth )a where Date(Order_date) >= Date_ADD('Day', -2, Date_ADD('Year', -1, current_date) ) order by Order_date
I got the results but when I compare order and customer count that is not matching with the expected count. Here I'm calculating day wise customer counts. But I need customercount and order count for whole year. For example: if I'm calculating orderamount, customercount, ordercount for april10 12 month rolling then the order date period should be 04-09-2019 to 04-09-2020 and similarly for other days aswell. Can any one please help me with the query? I was able to implement it in T-SQL. but not able to do in PostgreSql or Presto SQL.  |
