events | Github Pages for events | Static Site Generator library

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)

I sort of need help here, honestly not sure where I went wrong, here is the full code. I am sort of new, just trying to bring back the mention user and the reason back in a message instead of doing anything with this information.

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)

I'm writing a Firebase function (Gist) which

1. Queries a realtime database ref (events) in the following fashion:

   await admin.database().ref('/events_geo').once('value').then(snapshots => {

2. Iterates through all the events

   snapshots.forEach(snapshot => {

3. Events are filtered by a criteria for further processing

4. 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 => {

5. 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:

10:54:12.642 AM Function execution started

10:54:13.945 AM There are no emails to be sent in afterEventHostMailGoodRating

10:54:14.048 AM There are no emails to be sent in afterEventHostMailBadRating

10:54:14.052 AM Function execution took 1412 ms, finished with status: 'ok'

Super hyggelig aften :)

super oplevelse, ... long string generated

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?

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:

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

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 :(

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:

I'm making a POC with Lumen and Vue.JS. For now it just has to send a "hello world" message from the Lumen back-end to the Vue.JS front-end (which works). I have made an event which is triggered upon loading the page like this:
