kandi X-RAY | getting-started Summary
Two simple projects, made in Eclipse (Neon), for getting started with the OpenCV library (version 3.x) and with JavaFX (version 2 or superior). Please, note that both projects are Eclipse projects, realized for teaching purposes. Before using any of them, you need to install the OpenCV library and create a User Library named opencv that links to the OpenCV jar and native libraries. A guide for getting started with OpenCV and Java is available at

QUESTION
I have a two sets of data in database one is date and one is time. I display my data in calendar. I made one post request when user choose the date, that time will be selected for the user. I want to make one helper function when user's choosing time will be over I want to show them alert in front-end that "Your selected time expired!". I am using date-fns for date validation.
This is my code so far:
...ANSWER
Answered 2021-Jun-15 at 13:55Have a go with this
- No need for date-fns for trivial comparison
- I do string comparison, it works on same length strings. No need to create new dates for the time
I am not sure where you will pass the user time

QUESTION
Context: I followed this link on setting up AWS MSK and testing a producer and consumer and it is setup and working correctly. I am able to send and receive messages via 2 separate EC2 instances that both use the same Kafka cluster (My MSK cluster). Now, I would like to establish a data pipeline all the way from Eventhubs to AWS Firehose which follows the form:
Azure Eventhub -> Eventhub-to-Kafka Camel Connector -> AWS MSK -> Kafka-to-Kinesis-Firehose Camel Connector -> AWS Kinesis Firehose
I was able to successfully do this without the use of MSK (via regular old Kafka) but for unstated reasons need to use MSK now and I can't get it working.
Problem: When trying to start the connectors between AWS MSK and the two Camel connectors I am using, I get the following error:
These are the two connectors in question:
- AWS Kinesis Firehose to Kafka Connector (Kafka -> Consumer)
- Azure Eventhubs to Kafka Connector (Producer -> Kafka)
Goal: Get these connectors to work with the MSK, like they did without it, when they were working directly with Kafka.
Here is the issue for Firehose:
...ANSWER
Answered 2021-May-04 at 12:53MSK doesn't offer Kafka Connect as a service. You'll need to install this on your own computer, or on other AWS compute resources. From there, you need to install the Camel connector plugins

QUESTION
I have tried this tutorial and have successfully consumed kafka topics that are published on a server at my work place. I am not the producer, just purely a consumer. However, the code in that tutorial is to stream in a terminal. Now I want to try it with Python and record the messages into text file (or something of that sort).
This is the code I use, after reading a few more threads and tutorials (such as here):
...ANSWER
Answered 2021-Jun-08 at 23:07If you're able to use the WSL terminal with kafka-console-consumer, then running Python code there should work the same.
If you're connecting to a remote Kafka server, chances are the WSL2 network settings are simply not able to reach that address. (multiple issues elsewhere talk about WSL2 and not having external internet access) . Therefore, you should really consider running Python code on the Windows host itself. Otherwise, sounds like you'll need to adjust your network configurations.
The for loop will wait for new messages to a topic, not read existing data until you add another parameter to the consumer to tell it to
FWIW, you can use kafka-console-consumer ... >> file.txt to write out to a file

QUESTION
UPDATE: it seems i found a bug. Here the ticket on github i created. David will solve the problem during the day.
I simply tried to follow the Heroku guide to create a simple laravel app (even without db connection) and deploy on a Heroku app. However, it appears that when using Composer 2 there are problems (see log here). Rolling back to Composer 1 is all right. In the Heroku documentation it is indicated that Composer 2 is supported but obviously I am doing something wrong since it gives me an error.
when I push modifications to Heroku i get this error:
...ANSWER
Answered 2021-Jun-06 at 14:37Just an update: I also used this guide provided by Heroku devcenter to create a simple laravel app and deploy it on heroku and i got the same result.
I suppose it could be a problem with Composer 2, but reading Heroku docs I understood Heroku support Composer 2
QUESTION
I followed with success the "first steps" guide here to test the Instagram API.
I did it as suggested in the docs with an heroku app.
Now that I obtained my access token, I would like to test this NodeJS Instagram private API on my local machine, without having to deploy on Heroku only for development purposes all the time I make changes.
In practice, I would like to test it with localhost, instead of myapp.herokuapp.com.
I thought to add a redirect OAuth URI like https://localhost:8443/auth/ in the section of the image below.
As it requires the URI to begin with HTTPS, I guess I have to enable it in my Express JS, as explained here.
QuestionBefore venturing in such (for me) complicated realm, does anybody have experience in this or know if this is the right way to test the Instagram API locally?
...ANSWER
Answered 2021-Jun-08 at 06:51I was able to make it work with localhost, but it was very tedious.
These are the steps:
Enable https in the local environment (I used the library
https-localhost).[I don't know if this is mandatory] create a test app* from the main app (https://developers.facebook.com/docs/development/build-and-test/test-apps/)
Set the redirect OAuth URI to
https://localhost:/auth/and update also all other URIs in.../instagram-basic-display/basic-display/settings.Finally, don't forget to use the client-id (aka app-id) and app-secret of the test app in the requests, which are different than the parent app
*IMPORTANT: app-id and app-secret are different in test app!
