Remove the "MODE=LEGACY" from the url. Here is a working example:

Also ensure you use a supported H2 version. That is 1.4.x fro 7.16.x: https://docs.camunda.org/manual/7.16/introduction/supported-environments/

The BOM will inclcude H2 1.4.200.

Camunda Application not starting up on docker container

I have a simple cammunda spring boot application. which I want to run in a docker container

I am able to run it locally from IntelliJ but when I try to run it inside a docker it fails with below error message:

ANSWER

Answered 2022-Feb-25 at 11:07

I don't think this is Docker related. Maybe your build process copies files?

"The deployment contains definitions with the same key 'ct-camunda' (id attribute), this is not allowed" Check if you have packaged multiple .bpmn files into your deployment. Maybe you accidentally copied the model file in an additional classpath location. You seem to have two deployments with the same id. (This is not about the filename, but the technical id used inside the XML)

If you are using auto deployment in Spring Boot, you do not have to declare anything in the processes.xml. Use this only in combination with @EnableProcessApplication (or do not use both)

Using pyaudio to build a Metronome; wrong timing

ANSWER

Answered 2022-Feb-08 at 18:16

You want the play_audio function to be called every 60/bpm seconds, but the function call itself takes time: you need to read the file, open the stream, play the file (who knows how long it is) and close the stream. So that adds to the time from one click to the next.

To fix this problem, you could try subtracting the time it takes to run the play_audio function from the time you sleep. You could also experiment with running play_audio on a separate thread.

My skills with Ethereum are still not sharp enough to give you a proper answer, but I hope you get some guidance.

The error states that you are trying to transfer by a party A certain quantity in the name of another party B, to a third one C, but the amount you are trying to transfer, using transferFrom, is greater than the one party B approved party A to send.

You can check the actual allowance between to parties using the method with the same name of your contract.

Please, consider review this integration test from the web3j library in Github. It is different than yours but I think it could be helpful.

Especially, it states that the actual transferFrom operation should be performed by the beneficiary of the allowance. Please, see the relevant code:

From what I can see, in your SongManager you are creating Dictionary ret, but not adding any values to. Instead, you are trying to directly assign values: ret[timings] = notes_enc[name];. Dictionary is not an array, you should use Add() method, like this: ret.Add(timings, notes_enc[name]);

Webaudio timing performance

Asked 2021-Nov-02 at 12:49

The file below uses ToneJS to play a steam of steady 8th notes. According to the log of the timing, those 8th notes are precisely 0.25 seconds apart.

However, they don't sound even. The time intervals between the notes are distinctly irregular.

Why is it so? Is there anything that can be done about it? Or is this a performance limitation of Javascript/webaudio-api? I have tested it in Chrome, Firefox, and Safari, all to the same result.

Thanks for any information or suggestions about this!

Install airflow-scheduler-failover-controller

This is a step by step set of instructions you can take to get up and running with the scheduler_failover_controller.
Install the ASFC on all the desired machines See the above section entitled "Installation"
Run the following CLI command to get the default configurations setup in airflow.cfg scheduler_failover_controller init
Ensure that the base_url value under [webserver] in airflow.cfg is set to the Airflow webserver.
Update the default configurations that were added to the bottom of the airflow.cfg file under the [scheduler_failover] section a. Main ones include updating: scheduler_nodes_in_cluster, alert_to_email b. See the Configurations Section bellow for more details
Enable all the machines to be able to ssh to each of the other machines with the user you're running airflow as a. Create a public and private key SSH key on all of the machines you want to act as schedulers. You can follow these instructions: https://www.digitalocean.com/community/tutorials/how-to-set-up-ssh-keys--2 b. Add the public key content to the ~/.ssh/authorized_keys file on all the other machines
Run the following CLI command to test the connection to all the machines that will act as Schedulers scheduler_failover_controller test_connection
Startup the following Airflow Daemons a. webserver nohup airflow webserver $* >> ~/airflow/logs/webserver.logs & b. workers (If you're using the CeleryExecutor) nohup airflow worker $* >> ~/airflow/logs/celery.logs &
Startup the Airflow Scheduler Failover Controller on each node you would like acting as the Scheduler Failover Controller (ONE AT A TIME). See the above section entitled "Startup/Status/Shutdown Instructions"
View the logs to ensure things are running correctly Location of the logs can be determined by the 'logging_dir' configuration entry in the airflow.cfg Note: Logs are set by default to rotate at midnight and only keep 7 days worth of backups. This can be overridden in the configuration file.
View the metadata to ensure things are being set correctly scheduler_failover_controller metadata
Airflow provides scripts to help you control the airflow daemons through the systemctl command. It is recommended that you setup the airflow-scheduler, at least, for systemd. Go to https://github.com/apache/incubator-airflow/tree/master/scripts/systemd and follow the instructions in the README file to get it setup. Note: It is also recommended to diable the automatic restart of the Scheduler process in the SystemD file. So remove the Retry and RestartSec section in the default SystemD file.
Follow the instructions in ${PROJECT_HOME}/scripts/systemd/README.md to set it up.
