QUESTION
I'm developing a discrete even simulator for a very long, multiply re-entrant manufacturing process (parts go through a number of tools in a certain sequence, and often come back to the same tool multiple times). The overall flow of the program is working nicely and give the expected queue depths, congestion points etc, under various build plan scenarios. The challenge I have not yet found a way to resolve is that of a tool with capacity >1 which may run ,multiple parts at a time but it must start them all at the same time (i.e., they may run in a chamber or a bath for example that cannot be opened/accessed when one part is running to add another).
Thus, I'm looking for a way to implement a tool with, say capacity=4, so that at the start of a run if there are 4 or more items in its queue, it'll load 4 of them and run them, but if there is only one part at time zero, that one part runs and anything that comes into the queue while that one part is running has to wait until the run is over.
My code is rather too long and complicated to illustrate the problem, well but the problem is well-described by the famous simpy "fueling station" example (code below). The behavior of that I'm trying to get rid of is expressed in this code. That is, the fuel station has capacity = 2, a car comes up and takes one of the slots, then some time later another car arrives and takes the remaining slot. That's great for gas pumps but I'm trying to block later users from gaining access once a run is launched.
I could envision giving the tool a property like self.status and set status to 'busy' or some such thing when the tool is in use, or perhaps use self.res.users in some way to do that but I wonder if there is some more natively simpy way of getting my tools to behave in the desired way.
Thanks!
...ANSWER
Answered 2022-Apr-02 at 05:40So it seems to me each car grabs a pump, but what you really want is a pump to grab up to two cars at a time. So you need a process that does the batching. Here is a quick and dirty batch processor. I use a store for the input queue, and when every my yield get() gets a first entity, I check the queue for up to capacity more entities to process, What this yield really does is cause my process to wait when the queue is empty

I am testing a feature that uses a Kafka producer and listener, with the help of spring-kafka-test.
Both spring-kafka and spring-kafka-test are using the 2.8.2 version.
My test classes use the @EmbeddedKafka annotation as follows:
ANSWER
Answered 2022-Feb-21 at 16:13This is possibly a bug in the 2.8.2 version of spring-kafka-test.
Switching back to latest minor 2.7.10 version solved the issue, even though spring-kafka is still on 2.8.2.
QUESTION
I am trying to do a HGAM in order to separate my large dataset by Reservoir. One of my predictor variables is Season_Y, indicating the season and year it the sample was taken. Here is my code:
...ANSWER
Answered 2022-Feb-19 at 12:41If Season_Y really contains data like "Winter_2019" you are using the fs basis incorrectly. This basis is the equivalent of a random slope, but instead of a linear effect we get a smooth effect for each level of the grouping variable. The critical thing here is that you are producing a smooth (lots of them) so you have to pass it a continuous variable and Season_Y isn't continuous. If this is even doing anything sensible, it is just creating a random effect (intercept) and hence it would be much clearer in terms of the intention of the code to use:

Full disclosure: I am a student who has likely messed up some conventions, notation and best practices. I warmly welcome feedback.
I am trying to implement a version of the gas station example found in the SimPy documentation, attached here:
...ANSWER
Answered 2021-Dec-19 at 01:55I am still not sure what you trying to do. Why cannot the cars have a pending request while the truck is replenishing the container? Those requests do not block the truck from adding to the container.
Any way, I took a stab at it and here is what I cam up with
In this version, when the car gets to the pump it checks if the container has enough gas to refuel the car. If it does it will make the container request. If it does not, it will wait for the truck to arrive and replenish the gas station and then make the container request. The car knows when replenishment is done because I added a replenish_event to the gas_station which gets triggered by the truck when the truck finishes replenishment. If the car needs to wait, it can yield to this event. Note that more then one car can yield to this event.
QUESTION
In a C++ program, I get multiple chunks of PCM data and I am currently using libmp3lame to encode this data into MP3 files. The PCM chunks are produced one after another. However, instead of waiting until the PCM data stream finished, I'd like to encode data early as possible into multiple MP3 chunks, so the client can either play or append the pieces together.
As far as I understand, MP3 files consist of frames, files can be split along frames and published in isolation. Moreover, there is no information on length needed in advance, so the format is suitable for streaming. However, when I use libmp3lame to generate MP3 files from partial data, the product cannot be interpreted by audio players after concatted together. I deactivated the bit reservoir, thus, I expect the frames to be independent.
Based on this article, I wrote a Python script that extracts and lists frames from MP3 files. I generated an MP3 file with libmp3lame by first collecting the whole PCM data and then applying libmp3lame. Then, I took the first n frames from this file and put them into another file. But the result would be unplayable as well.
How is it possible to encode only chunks of an audio, which library is suitable for this and what is the minimum size of a chunk?
...ANSWER
Answered 2021-Oct-28 at 06:30I examined the source code of lame and the file lame_main.c helped me to come to a solution. This file implements the lame command-line utility, which also can encode multiple wav files, so they can be appended to a single mp3 file without gaps.
My mistake was to initialize lame every single time I call my encode function, thus, initialize lame for each new segment. This causes short interruptions in the output mp3. Instead, initializing lame once and re-using it for subsequent calls already solved the problem. Additionally, I call lame_init_bitstream at the start of encode and use lame_set_nocap_currentindex and lame_set_nogap_total appropriately. Now, the output fragments can be combined seamlessly.

How can I "de-tokenize" or concatenate or recombine each tokenized "window" text into a string. Each string could either be an item in a list or a row in a data.frame.

Given source and target dataframes in Pandas, I need to update a column in the target dataframe by an amount specified in a column of the source dataframe, for every match on a key column.
In the example below, the source and target dataframes are RecetteDF and InventaireDF, respectively. The key column common to both is Codes interne. Quantite Reserver in the target has to be incremented with values from Quantite requise from the source on matching key.
I've made it work, but it's really not optimal.
So far my function looks like this:
...ANSWER
Answered 2021-Sep-24 at 06:54You can use pandas.merge to pull Quantite requise in from RecetteDF whenever you have a match. The merge should be done using left, so that we preserve rows of InventaireDF even when there is no match. Here is some code that should work:
