QUESTION
Can someone help me investigate why my Chainlink requests aren't getting fulfilled. They get fulfilled in my tests (see hardhat test etherscan events(https://kovan.etherscan.io/address/0x8Ae71A5a6c73dc87e0B9Da426c1b3B145a6F0d12#events). But they don't get fulfilled when I make them from my react app (see react app contract's etherscan events https://kovan.etherscan.io/address/0x6da2256a13fd36a884eb14185e756e89ffa695f8#events).
Same contracts (different addresses), same function call.

Here's the code I use to call them in my tests

QUESTION
I am making a simulation with C (for perfomance) that (currently) uses recursion and mallocs (generated in every step of the recursion). The problem is that I am not being able to free the mallocs anywhere in the code, without having the wrong final output. The code consist of two functions and the main function:
evolution(double initial_energy)
ANSWER
Answered 2021-Jun-13 at 04:47You're supposed to free memory right after the last time it will be used. In your program, after the while loop in recursion, Energy isn't used again, so you should free it right after that (i.e., right before return event_counter;).

QUESTION
Iam using EventChannel to handle events from hardware barcode scanner. EventChannel is initialized in initState, in main class - it works through whole app. While change is detected, it inserts value into global variable (ValueNotifier - i dont know, if it is right) and then I need to work with that value in multiple widgets. I need some sort of widget, which will tell me, that value updated and it will trigger onEvent function - something like RawKeyboardListener. I tried using listeners, but when i do pushNamed, the listener is still listening and it runs code from previous pages, while scanning.
Is there any widget, that would be suitable for me? (cant use ValueListenableBuilder, because it has no "onEvent" function) Or is there any way, to remove and add listeners while moving between pages, or while modal bottom sheet is opened? (I need to access previous listeners, after Navigator.pop)
...ANSWER
Answered 2021-Jun-14 at 10:37I solved my problem by using listeners and ModalRoute.of(context).isCurrent.
QUESTION
I'm writing a Firebase function (Gist) which
Queries a realtime database ref (events) in the following fashion:
await admin.database().ref('/events_geo').once('value').then(snapshots => {Iterates through all the events
snapshots.forEach(snapshot => {Events are filtered by a criteria for further processing
Several queries are fired off towards realtime DB to get details related to the event
await database().ref("/ratings").orderByChild('fk_event').equalTo(snapshot.key).once('value').then(snapshots => {Data is prepared for SendGrid and the processing is finished
All of the data processing works perfectly fine but I can't get the outer await (point 1 in my list) to wait for the inner awaits (queries towards realtime DB) and thus when SendGrid should be called the data is empty. The data arrives a little while later. Example output from Firebase function logs can be seen below:

I'm probably mixing up my async/awaits because of the awaits inside the await. But I don't see how else the code could be written without splitting it out into many atomic pieces but that would still require stitching a bunch of awaits together and make it harder to read.
So, two questions in total. Can this code work and what would be the ideal way to handle this pattern of making further processing on top of data fetched from Realtime DB?
Best regards, Simon

I have events which is pulled from redux, and if the events array contains data, then updateData will be used to filter events into the state var data.
I have data and events both added to the dependency array as talked about here. but I'm still getting this error:

Answered 2021-Jun-15 at 18:54Because you are executing useEffect callback whenever data changes and you are changing data in useEffect callback.

I am querying a database for an item using R2DBC and Spring Integration. I want to extend the transaction boundary a bit to include a handler - if the handler fails I want to roll back the database operation. But I'm having difficulty even establishing transactionality explicitly in my integration flow. The flow is defined as

Answered 2021-Jun-15 at 18:32Well, it's indeed not possible that declarative way since we don't have hook for injecting to the reactive type in the middle on that level.
Try to look into a TransactionalOperator and its usage from the Java DSL's fluxTransform():

Here is my underdeveloped pygame ping-pong game, but my sprites(player&opponent) ain't moving, on giving a keyboard input. And when I quit the program, it yells an error pygame.error: video system not initialized. My pygame is the latest 1.9.6 version with all the files up-to-daee. However, I am certain that pygame.display is generating this error, but I even tried pygame.display.init() and that too didn't worked :(

First the movement is not working because to differentiate the keys, you use event.type to compare where it should be event.key. Try with for example :

People of Stack Overflow!
Thanks for taking the time to read this question. What I am trying to accomplish is to pivot some data all from just one table.
The original table has multiple datetime entries of specific events (e.g. when the customer was added add_time and when the customer was lost lost_time).
This is one part of two rows of the deals table:
I want to create a view of this table. A view that has one row for each distinct date and counts the number of events at this specific time.
This is the goal (times do not match with the example!):
I have working code, like this:

Install events
You can use events 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.
