I am making a simulation with C (for perfomance) that (currently) uses recursion and mallocs (generated in every step of the recursion). The problem is that I am not being able to free the mallocs anywhere in the code, without having the wrong final output. The code consist of two functions and the main function:

evolution(double initial_energy)

I am just curious does batch listener mode in Spring Kafka gives better performance than non-batch listener mode? If we are handling exceptions then we still need to process each record in Batch-listener mode. Non-batch seems less error prone, stable and customizable .

Please share your views on this as I didn't find any good comparison.

Sorry I don't show my variables or anything, tried to give information only pertaining to the questions. This 1 Sub is huge.

Currently my code allows a user to select multiple files, the files selected will be sorted in a specific format, then loaded into 2 different arrays. Currently loads Columns D:E into 1 array and Columns I:K into another array (from selected files QSResultFileWS, and returns those arrays to my destination FormattingWS. I'm still trying to learn arrays so if the methodology I used to do this isn't proper, be gentle.

I ran into less than ideal inlining behavior of the .NET JIT compiler. The following code is stripped of its context, but it demonstrates the problem:

I have a dataframe with several groups and a different number of observations per group. I would like to create a new dataframe with no more than n observations per group. Specifically, for the groups that have a largen number I would like to select the n last observations. An example data set:

Update: Added a simpler demonstration jsfiddle, https://jsfiddle.net/47sfj3Lv/3/.

reproducing the problem in much less code I'm trying to move away from jQuery.

Some of my code, for populating some tables, has code like this

I am trying to get the Coriolis matrix for my robot (need the matrix explicitly for the controller) based on the following approach which I have found online:

I need a way to force the compaction of the __consumer_offsets topic. In a test environment I tried to delete the file cleaner-offset-checkpoint and then kafka deleted many segments as you can see below. Is it safe to delete this file in a production environment?

Before removing cleaner-offset-checkpoint:

I have a question about how rebasing works in git, in part because whenever I ask other devs questions about it I get vague, abstract, high level "architect-y speak" that doesn't make a whole lot of sense to me.

It sounds as if rebasing "replays" commits, one after another (so sequentially) from the source branch over the changes in my working branch, is this the case? So if I have a feature branch, say, feature/xyz-123 that was cut from develop originally, and then I rebase from origin/develop, then it replays all the commits made to develop since I branched off of it. Furthermore, it does so, one develop commit at a time, until all the changes have been "replayed" into my feature branch, yes?

If anything I have said above is incorrect or misled, please begin by correcting me! But assuming I'm more or less correct, I'm not seeing how this is any different than merging in changes from develop by doing a git merge develop. Don't both methods result with all the latest changes from develop making their way into feature/xyz-123?

I'm sure this is not the case but I'm just not seeing the forest through the trees here. If someone could give a concrete example (with perhaps some mock commits and git command line invocations) I might be able to understand the difference in how rebase works versus a merge. Thanks in advance!
