I use the Aitdownloadablefiles extension for attachments, but I don’t think that’s because it is the same with other extensions that do the same thing.

matlab – Unexpected good performance

Currently I’m working on a NARX model with neural network with one-step ahead prediction on MATLAB using deep learning/neural network toolbox to predict the behavior of a rigid pendulum, showing that it can be used to model non-linear systems.

Training and Validation data

First, I trained my model with oscilations without a complete loop, but it goes to very high angles, well over 90 degrees, as shown in the figure above. And it worked really well when we apply similar testes (i.e. oscilations without a complete loop), it isn’t shown here.

Test data

However the unexpected part is when I apply a torque that completes a loop (i.e. it goes over 360 deg and stabilizes on 540 deg) as shown in the figure above, it works really well too. As if it was trained for it and as if it can reproduce the behavior a sine function, as shown in the figure below. Even the “bad” model (in red) predicted very well the behavior, such as frequency, damping, etc. But I can’t find a plausible explanation for this behavior, because tecnically it wasn’t trained for.

Results of the test and comparisons with the input

Does anyone has the insight of what it could be? Which properties of either NARX models or one-step ahead predictions made this possible?

8 – D8 update: ‘The website encountered an unexpected error. Please try again later.’ error

I recently updated my Drupal 8 installation, and for some crazy reason my site now displays a white screen and this line of text when I go to it:

The website encountered an unexpected error. Please try again later.

I have no idea why. It’s driving me absolutely crazy. When I check my site’s error log, I see the following error. Anyone have any clue how to fix this? I’ve been trying to find answers to an entire day now:

wireshark – Unexpected gratuitous ARP request for

I’m trying to understand all facets of MAC address spoofing by testing it on real world implementations. I have Kali set up in VMWare using bridged mode on Windows over LAN. I used Ettercap’s port-stealing feature to port-steal my smartphone (Samsung Galaxy S10).

I expected the switch in my router to be tricked into thinking that my Kali VM is my phone so that the switch forwards all traffic intended to go to my phone to my Kali VM. Instead, Wireshark displays an endless train of ARP requests from all of the devices in my network. Here is an extract:

Wireshark image 1

Every single ARP packet looks like this:

Wireshark image 2

Why does this happen and what is the purpose of this ARP request?

I want to ask if any of you have encountered a similar problem.
It happened to me several times when I clicked on the clock, everything froze for about half a second, the screen moved as if a new workspace was opening and all my programs closed without being asked to save active files.
I don’t know what causes this. I don’t load the laptop too much. I have enough ram and processing power and I don’t think it’s a crash.

This is part of the result of GraphDistanceMatrix

I want to get a shortest distance matrix. Official documentation shows that GraphDistanceMatrix returns the shortest distance matrix, but it is clearly not the case. For example, FindShortestPath[G,5,1], the result is {5,4,2,1}, then the distance should be 910, and 630 is given. I don’t know what matrix this is.
Am I using something wrong or is this not the shortest distance matrix? Is there a way to get the shortest distance matrix?
