Adding a constructor with parameters is a breaking change that removes the default .ctor. If you want to maintain backward compatibility in the library just add a second constructor overload and don't use default parameters in public api:

In which situations std::dynamic_pointer_cast fails?

Asked 2021-May-27 at 19:21

I'm having a problem that's driving me crazy. I made a minimum verifiable example, but it does not show the error.

Let's first think about this code:

ANSWER

Answered 2021-May-27 at 19:21

Summary of the facts...

WhiteNoise derives from Applicable
DelayLine contains a pointer to an Applicable
WhiteChorus derives from DelayLine and constructs the base class with a pointer to a WhiteNoise (not an Applicable, but derived from it)
WhiteChorus.do_something() tries to cast the base class's pointer to a pointer to a WhiteNoise.

This should succeed, since the pointer was constructed as as pointer to a WhiteNoise. If this isn't working in your test case (and we haven't got a reproducible example here) then I think there might be a problem with the constructor of WhiteChorus.

Note that I've removed the term Effect from the end of all class names. Life is too short.

jsTree ajax parameter not even sending requests

Asked 2021-Apr-30 at 08:51

I am copying everything from the docs of jsTree section about mySQL and php.

I've got no clue what could be wrong, I delibratly have changed nothing from the example given, to make sure it is not my fault and still, nothing. I know that it should not function fully, because the links are not real routes on my server, but it still should at least attemt to contact them, but I do not see this communication in my browser (F12->network).

I did try to modify everything with real routes on my server but still, nothing.

Your insert returns 1 on success and 0 on failure. If you want to use the primary key, use getId() of the object you used to insert.

QUESTION

Windows command prompt creating but not redirecting output to file

Asked 2020-Dec-18 at 00:26

I'm having the opposite problem of so many posts I've seen on here.

I'm running a perl command written by someone else and the output is all being forced to the screen despite using the ">" command.

Windows clearly knows what I'm intending because the file name I give is being created fresh and new every time I execute my command but the contents/size of the log file are empty and 0 bytes long.

My perl executable lives in a different place than my perl routine/.pl file.

I tried running as administrator and not.

This is not something wrong with the program. Some of my coworkers execute it just fine and there is no output to their screens.

The general syntax is:

ANSWER

Answered 2020-Dec-18 at 00:23

It could be that the output is being sent to STDERR, while you are capturing STDOUT. Append 2>&1 to capture both to the same file.

Is it possible to connect mobile with USB camera and Macbook/Windows at a same time to debug the Android Application?

Asked 2020-Sep-01 at 09:33

I want to create an Android application where I can process the Images from a USB Camera and run ML detections on them. I have Pixel 2XL, Logitech C920, and Macbook Pro, which I want to connect at the same time, so I can debug the application whenever it crashes/does not run. Right now, I am using ALogic type C dock, but it is not detecting the Mobile device for USB Debugging. Is there any way where we can debug the app?

...

ANSWER

Answered 2020-Sep-01 at 09:33

well, I'm doing exactly the same and I'm using ADB over Wi-Fi for keeping my one and only USB-C available for wired UVC devices

short howto:

attach your device with USB-C cable, make sure it's one and only device (no emulators also)
optionally: check with adb devices is it visible
run adb tcpip 5555
disconnect device and check it's IP in some WiFi settings
run adb connect :5555
optionally: ensure with adb devices is it visible

now you can see your device in Android Studio as long as laptop/PC and Android device are connected to the same Wi-Fi

good luck!

ANSWER

Django keeps a reference to all executed queries in a ring buffer when settings.DEBUG = True

From DEBUG documentation

It is also important to remember that when running with DEBUG turned on, Django will remember every SQL query it executes. This is useful when you’re debugging, but it’ll rapidly consume memory on a production server.

Setting DEBUG = False should address your issue.

Install ALog

The Arduino IDE (Integrated Development Environment) is the current programming environment we use to write and upload programs to the ALog. (Other options exist, but this is the most beginner-friendly.) We haven't yet tested the brand-new web editor, so we'll be suggesting an old-fashioned download. And if you're deploying these in the field, you'll need the downloaded version! Go to https://www.arduino.cc/en/Main/Software. Get it, install it, go.
The ALog boards are "third-party" Arduino boards, so you'll have to set up support for these boards yourself. We've made a pretty thorough walkthrough that you can view here at https://github.com/NorthernWidget/Arduino_Boards, and have included those installation instructions here, immediately below. Each board will be added as an entry to the Arduino Tools > Board menu. Go to File > Preferences (or Arduino > Preferences on Mac). @image latex Arduino_Boards/File_Preferences.png "Arduino IDE preferences".
The ALog also relies on some custom software libraries. These are collections of computer code that help make everything from running basic data logging utilities to interfacing with specific sensors easier. We're introducing you to these libraries up here, even though they won't be needed until quite a bit further down. While we highly recommend them and they are very helpful for field work, you can also program the ALog without them! In fact, the earlier examples (below) do not include the custom libraries.

Support

Printed below is the template function designed to guide users about how to add support for additional sensors. You may also look at ALog.cpp and ALog.h for our current examples, and feel free to contact us (info@northernwidget.com) if you have questions about how to properly incorporate new sensors.
