Firebase Stream function not working correctly - firebase
I am working with ESP8266 and Firebase-Arduino library. I am trying to use the stream function but I am facing a problem with Firebase.available().
I know that Firebase.available() returns a true value whenever a change occurs on the real time database. But in my case it returns a true value every 30 seconds irrespective of the change has taken place or not.
Is this normal?
If not then how to fix it?
I am using the example code provided for FirebaseStream.

Logic App using HTTP Action to access and GET Jira ticket
So I followed this answer and it works fine: https://stackoverflow.com/a/74981947/20829088 Provided URL: https://<YOUR_DOMAIN>.atlassian.net/rest/api/2/search?jql=project=<PROJECTID>&fields=issue,status,name&startAt=0&maxResults=8000 However, it take a lot of time. So, if I want the url to check for specific ticket depending on created time and type of ticket. For example I want ticket that is created within 15 days and that are NOT a sub-task. so I tried something like this. .....&fields=issue,summary,issuetype&created>=-15d&hierarchylevel=0 I'm not sure of how it should be written I just tried this and it doesn't work. Here is the request result in JSON: It should be earthier [subtask=false] OR [hierarchylevel=0] OR [name=Task]
After reproducing from my end, I could able to achieve this using Condition connector of logic apps. I have initialized an array variable first and then tried to append each item that satisfies the condition. Below is the flow of my logic app.
and then I used Parse Json to retrieve the required values for condition comparision
You can use the below Code view to reproduce the same in your environment.

Q - Postman: How to clear collectionvariables between tests
I'm new to API testing through postman and i'm currently trying to figure out how to clear down my collection variables between automated tests. Here is my code below - Thanks so much for anybody who can point me in the right direction.
Warning :
pm.collectionVariables.clear()
will delete all your collection variables:
pm.collectionVariables.unset("variablename")
will delete that particular variable.
so if you just want to reset the value to initial value then:
in the first request add:
pm.environment.get("resetValue") ? null:pm.variables.set("resetValue",pm.collectionVariables.toJSON().values)
Here we store data only if resetValue variable is not set
And in the last request:
pm.environment.get("resetValue").forEach((a)=>pm.collectionVariables.set(a.key,a.value))
pm.environment.unset("resetValue")
This make sure you don't set resetValue incorrectly if you are running first request multiple time
you can also use pm.variables if you don't any variable to be affected , thats the better way
Moment misunderstanding utcOffset
I'm working with moment and moment-timezone and I don't get it. Can anyone explain me why this happens?
THIS (which is what I want):
moment('2018-11-28T00:00:00.000-02:00').toISOString()
Prints 2018-11-28T02:00:00.000Z
BUT:
moment('2018-11-28T00:00:00.000').zone('-02:00').toISOString()
moment('2018-11-28T00:00:00.000').utcOffset('-02:00').toISOString()
Both print 2018-11-27T23:00:00.000Z
PD: My zone is GMT+1.
Why are different? it is not supposed to be equals?
How do I set the offset (not in the constructor but with a method after I have de moment object)?
Thanks! BR
As I can see, you want to keep the existing time of day when using utcOffset method. It accepts a second parameter, which is a boolean. As the documentation says:
Passing true will keep the same local time, but at the expense of choosing a different point in Universal Time.
// "2018-11-28T02:00:00.000Z"
moment('2018-11-28T00:00:00.000').utcOffset('-02:00', true).toISOString();
For more information check the documentation
How to read documents from Change Feed in Azure Cosmos DB since last checkpoint after restart?
I am using Change Feed processor library to read the Change Feed on a partitioned collection and below is the code for how I have configure it. I ma using most of the default options.
ChangeFeedProcessorOptions feedProcessorOptions = new
{
LeaseRenewInterval = TimeSpan.FromSeconds(15),
};
var docObserverFactory = DocumentFeedObserverFactory.Create(this.destinationCollectionInfo, this.dbRepository);
this.builder
.WithHostName(hostName)
.WithFeedCollection(this.monitoredCollectionInfo)
.WithLeaseCollection(this.leaseCollectionInfo)
.WithProcessorOptions(feedProcessorOptions)
.WithObserverFactory(docObserverFactory);
This runs fine as long as the Change Feed application is running and documents are being inserted/updated in the collection and the Change Feed app picks them up as expected.
The problem happens when I stop the Change Feed app for sometime and insert/update few documents in the Collection. Then when I start the Change Feed app, it doesn't pick changes from where it last left. Those changes that were inserted when the Change Feed app was stopped are lost. But when I set the flag StartFromBeginning to true, it picks everything from the start including changes that were inserted when the Change Feed app was stopped in between for sometime.
My understanding of read from current (StartFromBeginning to false) is that the Change Feed reads documents since it last left. But that doesn't seem to happen. Please help.
There are two ways to continue from exactly where you left it. The first, and more accurate one, is to store the Continuation token of the last thing you read. That way you can specify it when you start again and it will win over both the StartTime and the StartFromBeginning flags. The second one is to provide the StartTime property which will try and find the continuation token of a given time automatically. It has an approximate 5 second precision so there is a chance that you might miss some documents though.
Qt: Mobility GeoLocation works on Simulator but not on N900
I use the following code to get GeoLocation for my app
QGeoPositionInfoSource *source = QGeoPositionInfoSource::createDefaultSource(this);
if (source) {
source->setUpdateInterval(1000); // time in milliseconds
source->setPreferredPositioningMethods(QGeoPositionInfoSource::AllPositioningMethods);
connect(source, SIGNAL(positionUpdated(QGeoPositionInfo)), this, SLOT(positionUpdated(QGeoPositionInfo)));
source->startUpdates();
source->requestUpdate(30000);
const QGeoPositionInfo &info =source->lastKnownPosition();
ui->label->setText(QString("Latitude - %1 Longitude - %2").arg(info.coordinate().latitude()).arg(info.coordinate().longitude()));
}
This code runs perfectly on the Simulator and gives me the coordinates provided by the simulator however this does not work when i try to run it on my N900. It returns Nan instead of the latitude and longitude coordinate. The current GPS signal on the phone is coarse accuracy. Also geolocation is working in the OVI Maps app on the phone. Any idea why the above code is unable to get the geolocation on the phone but works perfectly on the simulator ?
You should be setting the label from the slot for positionUpdated() as the signal is fired when an update has been received. Your call to requestUpdate() also triggers the positionUpdated() signal. If it does not get an update after your timeout setting, it will signal requestTimeout() which you might want to connect a slot to for informational purposes. It is likely that when you retrieve lastKnownPosition(), no position has been determined yet and the value returned is a null value. It's difficult to be sure just from the documentation but I think it implies that requestUpdate() will always return immediately, not after it has successfully received an update so you should call source->lastKnownPosition.isValid() to see if it contains a good position. You should really be checking the position in the positionUpdated() slot or after that slot has been called at least once. It's likely the simulator has a postion available immediately and works in that case. Does your positionUpdated() slot ever get called?
