gui | Super minimal , rock-solid foundation

I'm currently working on a project running a jboss backend server (server-ear:ear exploded artefact) and a java gui (java 11) as frontend.

The backend contains a java service bean which accesses a database server and throws a custom exception (extends exceptions), if the variable is not found. The GUI catches the custom exceptions with a try and catch block.

The code is build and run inside of Intellij + Maven.

If i try to execute the code following arrow pops up at runtime:

I build a script to filter several Messages out of a log file. The file im using right now has around 400.000 lines and when im looking for a match with the following code he takes very long since i added the progress bar. Is there a way to make it more efficient. If im right the reason for it to take so long is that he refreshes the progressbar Gui with every line he passes.

Current situation : I have one GUI program(written by python) which using sqlite data stored on my computer.

Wishlist: I would like to have one server computer to locate sqlite data (DATA A1) (CRUD operation needed) and ten more client computer using GUI program(written by python) which connect with the sqlite data (DATA A1) on lan.

I have no idea how to set up this program and server and what I need to learn more.

Current example code for check product in shop:

I am trying to install all needed modules for an existing Django project. When I run pip install -r requirements.txt I get the following errors:

I have a function to change an image and its opacity in a JavaFX GUI:

I wrote GUI using PySide2, numpy and matplotlib which works without any problm without problem on MacOS 11.2.3. However I get an error when running the code on Ubuntu 20.4 and The code works

I made a GUI using PySide2 and matplotlib. The goal is click on an image and store the coordinate of the clicks in a csv. After launching the application on Ubuntu and having clicked on the "button" button, I get an error message (provided after the code). It seems that under the Linux, the code is being run until line 91 (although no clicks where made on the image yet and therefore, the dataframe to store them is obviously empty) while on MacOS, the interpreter has stopped at line 76 waiting for the clicks of the user (on MacOS the picture has launched and there is nothing on the terminal)

Here is the code:

I'm trying to use Apache Nutch 1.x Rest API. I use docker images to set up Nutch and Solr. You can see the demo repo in here

Apache Nutch uses Solr as its dependents. Solr works great, I'm able to reach its GUI at localhost:8983.

However, I cannot reach Apache Nutch's API at localhost:8081. The problem starts here. The Apache Nutch 1.X RESTAPI doc indicates that I can start the server like this 2. :~$ bin/nutch startserver -port [If the port option is not mentioned then by default the server starts on port 8081]

Which I am doing in docker-compose.yml file. I'm also exposing the ports to the outside.

I have written a GUI application in C++, built it for ARM processor and verified, that this application is running on Android in the Andronix emulated environment. Now is the question: How can I enable running this application on Android natively, without any emulated environment? I would like to create an APK file for installing it in a usual way. Are there any tools, which allow creating an APK file and packing an executable file into it?

My GUI is able to play videos automatically when selected in the QListWidget. However, instead of normal speed, the videos play very fast. I use 720p Mp4 videos as examples and are placed in a certain folder. I tried using cv2.CAP_PROP_FPS and cv2.CAP_PROP_BUFFERSIZE, but they are both not working. I am using pyqtSignal in the QThread and the convert_cv_qt function which I saw in other guides. How do I play the videos in normal speed / frame rate?
