kandi X-RAY | YaEtl Summary
YaEtl ("Yay'TL", or YetAnotherEtl) is a PHP implementation of an Extract-Transform-Load (aka ETL) workflow based on NodalFlow. ETL workflow comes handy in numerous situations where a lot of records meet with various sources, format and repositories. YaEtl extends this pattern allowing you to chain any number of E-T-L operations with some extra capabilities such as Joining and Qualifying. YaEtl can even just Extract and load with no transformation involved, or even just load or transform. If we where to acronym the workflow behind YaEtl, it could result in NEJQTL for Nodal-Extract-Join-Qualify-Transform-Load workflow. NodalFlow is the underlying and even more generic implementation of an executable directed graph upon which is build YaEtl. The directed graphs are composed of Nodes which are somehow executable, accept one parameter and may be set to return a value that will be used as argument to the next Node; or not, in which case the previous and untouched argument will be passed to the next Node up to the Flow exec argument if any. Nodes can also be traversable (data generators etc ...) in which case they will be iterated over each of their values in the flow until they run out. When a node is "traversed", each of the values yielded will trigger the execution of the successor Nodes with or without the yielded value as argument, depending on the traversable node properties. Each of these directed graph can be invoked by any other instance in the process as well as by each Nodes and at any Node position, which effectively can turn any set of such graphs into an executable network of Nodes. The major interest of such design is, in addition to organize complex task with ease, to create reusable and atomic tasks. Each Node in the workflow will be reusable in any other workflow just and strictly as it is. And this can represent tremendous time saving along the way, actually, just more and more over time and as the code base grows. Being Nodal makes it possible to chain arbitrary number of Extract to Load operations which may go through arbitrary number of transform, joins and, to even branch the workflow in case some Loaders require different transformation and or joins before they can do their work.

QUESTION
I'm currently wokring on a product with the following conditions:
- Spring-Boot (2.6) with Camunda embedded (7.16)
- Connection to Camunda configured to use H2 (2.1.210) embedded with the following is configured in application.yml:
ANSWER
Answered 2022-Mar-09 at 08:50Remove 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.

I have the following dataframe [1] which contains information relating to music listening. I would like to print a line graph like the following 2 (I got it by putting the data manually) in which the slotID and the average bpm are related, without writing the values by hand . Each segment must be one unit long and must match the average bpm.

QUESTION
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:
08043 Exception while performing 'Deployment of Process Application camundaApplication' => 'Deployment of process archive 'ct-camunda': The deployment contains definitions with the same key 'ct-camunda' (id attribute), this is not allowed
docker-compose.yml
...ANSWER
Answered 2022-Feb-25 at 11:07I 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)

So I wanted to build a metronome and decided to use pyaudio. I know there are other ways but I want to make something else later with that.
Thats my Code so far:
...ANSWER
Answered 2022-Feb-08 at 18:16You 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.
QUESTION
I am trying to send test USDT to a particular account in Java using the following code:
...ANSWER
Answered 2022-Jan-04 at 18:26My 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:
QUESTION
full error:
...ANSWER
Answered 2021-Dec-25 at 14:11From 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]);
QUESTION
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!
...ANSWER
Answered 2021-Nov-02 at 12:49For a scheduled triggerAttackRelease, you should pass the time value as the third argument.
