            Drawing Poincare Section using Python
            Asked 2021-Dec-10 at 15:09

            I was about to plot a Poincare section of the following DE, which is quite meaningful to have a periodic potential function V(x) = - cos(x) in this equation.

            After calculating the solution using RK4 with time interval dt = 0.001, the one that python drew was as the following plot.

            But according to the textbook(referred to 2E by J.M.T. Thompson and H.B. Stewart), the section would look like as

            :

            it has so much difference. For my personal opinion, since Poincare section does not appear as what writers draw, there must be some error in my code. However, I actually done for other forced oscillation DE, including Duffing's equation, and obtained the identical one as those in the textbook. So, I was wodering if there are some typos in the equation given by the textbook, or somewhere else. I posted my code, but might be quite messy to understand. So appreicate dealing with it.

            If you factor out some of the computation blocks, you can make the code more flexible and computations more direct. No need to reconstruct something if you can construct it in the first place. You want to catch the points where w0*t is a multiple of 2*pi, so just construct the time loops so you integrate in chunks of 2*pi/w0 and only remember the interesting points.

            Dns lookup for docker container breaks after ~36 hours of uptime
            Asked 2021-Oct-15 at 08:11

            I have a single container deployed via docker-compose (dns is done through the docker daemon dns server 127.0.0.11) on a host with dns server configured for a private network in the /etc/resolv.conf and no access to the internet.

            The container runs fine for a while (about 40 hours) then starts failing its dns lookups with timeout messages: the application logs show failures against the docker dns server:

            Further inspection of the host showed that the java application in the target container was holding a lot of tcp sockets.

            After fixing the above, the connection issue did not occur any more. Presumably we hit a limit on the amount of open sockets a container can have.

            (MATLAB/C++) Is it possible to pass functions as arguments to C++ MEX functions?
            Asked 2021-Feb-13 at 01:10

            I have only been working with mex functions for a couple of weeks, and am now working on writing a Runge-Kutta, 4th order solver as a C++ mex function. I am wondering whether it is possible to take a function as an input. Effectively, it would be nice to have my dynamics function written in MATLAB and pass it straight through to my RK4 mex function. For example, if the dynamics are governed by Duffing's equation, written in MATLAB:

            Just quickly skimming the MATLAB C++ API doc, it looks like you can do this using the matlab::engine::MATLABEngine::feval interface found here:

            I.e., pass your function name into the C++ mex file as a string which you can get from the ArgumentList via the matlab::data::CharArray syntax:

            The main point to keep in mind is that you have to create 2D arrays of the velocities of the vectorfield U, V by using the meshgrid np.mgrid. Use the code below as a starting point and don't forget to play around with the options of streamplot.

            How Can I Make Sly's Backtrace Be Sensible?
            Asked 2020-Jan-11 at 21:49

            Whenever I get an error, Sly displays restarts and backtrace. I've seen people on the internet who have readable backtraces that are sensible function calls. When I enter (fun duf) in the repl, I end up with something like this:

            ...

            ANSWER

            Answered 2020-Jan-11 at 21:49

            I think that you feel that a lot of what you are seeing is “garbage” just because you do not yet know what it is.

            • In line 9 and 8, you see the functions that the REPL is using to handle your input. At this stage, the input is a string, as you can see.
            • In line 7, there are some bindings put on the stack, so that the right package is used, and * to *** are bound to the last results (a handy feature for a REPL).
            • In line 6, call-with-listener is probably establishing that output should go to Sly.
            • In line 5, this anonymous function is the one contained in the closure that has been an argument on line 6. In other words, an implementation detail.
            • In line 4, the retry restart is established. This frame is where control would be transferred if you invoked the Retry restart in the debugger.
            • In line 3, you again see a function argument being executed. Note the call-with-… naming convention.
            • In line 2, you see that your input has been read, i. e. transformed into a lisp datastructure. It is now evaluated with the standard function eval.
            • In line 1, you see how SBCL does that in this case — an implementation detail.
            • In line 0, you see some anonymous function, again something that comes from evals implementation.

            There is not much to see here, because the first thing eval does is to evaluate duf, which fails.

            The computer has no idea which part of the current stack context you are trying to debug. It therefore must show you the entire backtrace, or suffer the wailing of people that got the information withheld they were interested in.

            What you need to learn is to recognize where the stuff you are interested in starts. Here, all that Slynk stuff (obviously?) is below your context, so you really only need to look at the part until the first eval line. In this case, that's just the first line, which makes sense, because the line you entered simply fails at the first lookup. For a Sly developer, those lower stack frames might be interesting.

            Of course, in more realistic scenarios, there are some implementations that have more legible backtraces than others. That's not something Sly can do something about. What it does do is to give you the option to jump from any line in the backtrace to the corresponding source file position, if available (in SLIME, it's v (view), don't know about Sly). There is a lot more that you can do, e. g. inspect local bindings/variables/arguments, and invoking restarts. Take a look at the manual.
