QUESTION
I am getting a failure trying to join a KSQLDB cluster and serve requests. I made an image that explains the issue better than I can write it. Box titled "Cluster Fails" is my issue.
Funny part is that it definitely attempts to cluster because I get {"@type":"statement_error","error_code":40001,"message":"Unable to execute pull query: when I make a call to 192.168.150.125:8087
@Robin Moffatt So for version of KDQLDB it is the latest the docker image used is
...ANSWER
Answered 2020-Jun-23 at 22:25Before pull queries were introduced, ksqlDB nodes did not talk to each other. The 'clustering' of ksqlNodes leveraged a shared command topic and the Kafka consumer groups protocol of Kafka to share out work. This is why you're not seeing any messages about trying to join the cluster: the node doesn't join the cluster.
Pull queries using Kafka Streams' interactive queries under the hood. This works by each ksqlDB node advertising an endpoint other nodes can reach it. These advertised endpoints are shared between ksqlDB nodes using the Kafka consumer group protocol, i.e. the nodes become aware of each other through their communication with Kafka.
When you issue a pull query to a node that doesn't host the information you require it will attempt to forward the request to the node that does by contacting it on the endpoint it advertised. In your case, what is happening is that the endpoint your nodes from one machine are advertising is not accessible from the other machine.
KsqlDB v0.8 - 0.9 takes the first listener in the listeners config and uses this as its advertised listener / endpoint. A common problem is people use a wildcard or loopback address in their listener config, e.g.

I'm writing a script to calculate the Ackerman steering geometry of a car.
Input: T is linear set of numbers
Output: a uses T to calculate some numbers that I can plot.
Within my output there are several other functions that also contain T as an input.
How do I make it so that my final output is the same size as my input?
I've tried pulling out all the inner functions and replacing them with their equations but I still got the same error.

I want to create a dictionary with a predetermined list, however, I can't seem to figure it out how to avoid overwriting instead of appending, and I'm not sure if I can avoid importing any other modules.
The scope is that I have a data frame of 1 column of character names with ID numbers attached to the names from reading an excel file in, sega_df:
ANSWER
Answered 2018-Jun-21 at 16:45You should define slice as an empty dictionary outside of your loop. As it currently stands, you redefine the dictionary for each character as you iterate.
QUESTION
I intend to model a trivial game-play (HTTPReq/HTTPResp) using Akka Streams. In a round, the player is challenged to guess a number by the server. Server checks the player's response and if the what server holds and what the player guesses are the same, then the player is given a point.
A typical flow is like this:
- Player (already authenticated, sessionID assigned) requests to start a round
- Server checks if the sessionID is valid; if it is not, the player is informed with a suitable message
- Server generates a number and offers to the player, along with a RoundID
... so on. Nothing extraordinary.
This is a rough arrangement of types and the flows: ...ANSWER

For this particular use case I would generally agree that a partition & merge setup is "unnecessary work". The other stack posts, referred to in the question, are for the use case where you only have Flow values to combine without the ability to manipulate the underlying logic within the Flow.
When you are able to modify the underlying logic then a simpler solution exists. But the solution does not strictly lie within akka's domain. Instead, you can utilize functional programming constructs available in scala itself.
If you rewrite the numberTofferToPlayer function to be a PartialFunction:

I've written a python script that generates several data frames, then sums them together into one final dataframe. The final dataframe, df is then written into an Excel sheet (along with many other sheets that contain the dataframes written before) in an Excel Workbook. The final data frame is a value given to several names per month, something like this:

into a previously created excel sheet's cells
The xlsxwriter docs state: "XlsxWriter is a Python module for writing files in the Excel 2007+ XLSX file format. ..... It cannot read or modify existing Excel XLSX files." (Link Here). So you cannot modify an existing .xlsx file using xlsxwriter.
If you're okay with creating an original .xlsx file, then with xlsxwriter it's relatively straightforward to create the type of Chart you are looking for. I've provided a fully reproducible example of this below.

I am starting a project with Python and PyQt5. I would like to have a timeline widget like that
So in the futur I would like each rectangle to be a button, but my main issue at the moment is to make the timeline stick to the width of my window.
At the moment, my timeline inherits from QFrame, and each rectangle is a QFrame too. So is it a good way to do it ? Is there a better way to do it ?
Here is what I tried :
Main.py
...ANSWER
Answered 2017-Dec-17 at 22:43A simple solution for this case is to overwrite the resizeEvent() method, that method is called every time the widget resizes, so we take advantage of that method to change the width of line1 and line2, but so that these QLabel can be accessed from that method must be members of the class, for this you must change line1 and line2 to self.line1 and self.line2:
