            Python code has a big bottleneck, but I am not experienced enough to see where it is
            Asked 2021-Dec-22 at 08:38

            I won't tell you where the bottleneck is, but I can tell you how to find bottlenecks in complex programs. The keyword is profiling. A profiler is an application that will run alongside your code and measure the execution times of each statement. Search online for python profiler.

            The poor person's version would be debugging and guesstimating the execution times of statements or using print statements or a library for measuring execution times. Using a profiler is an important skill that's not that difficult to learn, though.

            Mongodb "like" on multiple fields in aggregation
            Asked 2021-Dec-07 at 11:57

            So I have some user documents that have first names and names. I'd like to offer the possibility to filter them if a given input "looks like" that fullname.

            ...

            ANSWER

            Answered 2021-Dec-07 at 11:57

            For aggregation you can use $function to execute custom code. However that kind of defeats the purpose of pagination as Mongo has to execute this code for each document, additionally it is recommended not to execute js in Mongo as it has somewhat bad performance.

            It seems like you're just using the wrong database for the job, If this is a crucial feature I recommend trying a text search db like atlas search or elasticsearch

            If changing db is not an option, and this feature is too important to remove or alternate. maybe if your provide additional detail as to how the scoring works it'll be easier to give a full answer.

            What happened

            If you do not reply or acknowledge the interaction in 3 seconds. There's a cooldown!
            The user will see interaction failed and the reply gate is closed.

            Solution

            However, if you defer the reply and edit later, the gate will open until you update the defer or edit the reply. Here's how to do it, and here's the documentation about it.

            Python convolution with histogram and Gaussian
            Asked 2021-Aug-13 at 09:44

            I have a simulated signal which is displayed as an histogram. I want to emulate the real measured signal using a convolution with a Gaussian with a specific width, since in the real experiment a detector has a certain uncertainty in the measured channels.

            I have tried to do a convolution using np.convolve as well as scipy.signal.convolve but can't seem to get the filtering correctly. Not only the expected shape is off, which would be a slightly smeared version of the histogram and the x-axis e.g. energy scale is off aswell.

            I tried defining my Gaussian with a width of 20 keV as:

            ANSWER

            Answered 2021-Aug-13 at 09:44

            As you may be aware, doing the convolution of the two histograms with the same bin size will give the histogram of the result of adding each element of one of the samples with each elements of the other of the samples.

            I cannot see exactly what you are doing. One important thing that you seem to not be doing is to make sure that the bins of the histograms have the same width, and you have to take care of the position of the edges of the second bin.
