blinkt | Rust library for the Pimoroni Blinkt

I've been working on a rock paper scissors game against the computer on my raspberry pi. I have the Blinkt HAT installed on it so I can show the score and play a nice animation when someone has won. Everything works fine but I want to make a nicer winning animation

This is where the problem comes in. I wanted to write a code that lights up some of the LEDS at the same time. But when I tried to make some code it didn't work. I went looking into the examples that the blinkt comes with the library and I found one example that nearly does what I needed. It is called pulse.py. But I don't understand some part of the code:

I am trying to make a mini 8-bit binary display using Pimoroni Blinkt! on Raspberry Pi, and when I input a binary number, it outputs random numbers: I enter 00010011 and it outputs 4105, when it should output 00010011

My code:

I know the topic has been covered a few times however I have attempted, or at least tried virtually all solutions however being a fairly new python basher I've not been able to get any of the previous solutions to work.

The basic premise of the script is that its subscribed to a MQTT broker and waiting for commands, the single action commands work 100%, however one of the commands required a loop to run indefinitely until another command is received, thus the most appropriate solution was to run the "loop" in a separate thread while the main subscriber loop continues to "listen" for the next command.

Everything is working 95%, the "static" commands come through and the tasks is run fine, then when the "mtg" command comes through it actions the thread and the loop runs 100%, however this is where it falls down, when the next command is received I can confirm the "if" statement processes the command as it prints the message to the console, but the thread.stop() is not run, or it may be run but it does not terminate the thread --- I'm pulling my hair out trying to figure it out.

Some code:

I am facing issue to connect VPN on Android 10 and getting below message in logcat. This is Error of permissions. Looking for solution. Also added android:requestLegacyExternalStorage="true" in Mainfest but not work for me.

D/ConnectionStatus: IO Exceptionjava.io.IOException: Cannot run program "/data/user/0/com.casvpnapp/cache/pie_openvpn.x86_64": error=13, Permission denied

I have a service running in conjunction with a Notification (System). When the service stops (and/or the app stops), the notification should be cancelled (i.e. not showing on the status bar anymore).

Going through the provide Android Dev guide of Notifications, I did not find any info on how to close a notification.

Going to SO, I found a number of questions.

1.

To summarise @nipun.birla's answer to how one should cancel Android notifications:

To Cancel a Notification, try in order:

1. NotifcationManager.cancel(int) with notificationID

2. NotificationManager.cancel(String, int) with notificationID and notificationTag

3. NotificationManager.cancelAll() as final attempt

What was not mentioned though, is what should one do if none of these work.

2.

One should use cancelAll suggestion

3.

This SO thread contains a good example of a Started Service example with an associate notification implemented into the service lifecycle (where the notification is also killed) - See here for Started Service details

4.

Here a suggestion was made to delete the PendingIntent associated with the notification

5.

A couple more questions and solutions reflecting the same info above: See this, and this, and many more...

6.

An very interesting question and solution on programmatically hiding a notification icon in the status bar

My Problem

By now it should be fairly obvious, my notification does not cancel itself asked to do so.

Implementation:

See below for full implementation, although I will post the general usage of the helper class and core functions

Build Failed On Android on windows

Android Build Failed for building ics-openvpn with NDK,CMake, LLDB

I wanted to build this open source package

https://github.com/schwabe/ics-openvpn

I have added CMake, LLDB and NDK to the Android Studio SDK

I also added the swig.exe path

However it fails with the following output in android studio console output log Let me know if you know why this error happens

Excuse me for the very broad question, but I seem to be going around in circles.

I'm looking to build/develop a web application, using a MySQL database and host it on my RPi.

In trying to do so, I've learn that I need a webserver (apache2 seems to be the one these days) and that I needed to create an application to interface between them.

Initially, I was using Python and Qt to try and build an app to be the interface, but found out that things weren't simple and I used to use Python/MySQL connectors etc.

After a few weeks, I got things connected and then thought about the building of it. It became apparent that options like Flask & Django would be better suited for the task due to the frameworks.

I found the DjangoGurls tutorial simple to follow when I read through it, so decided to give it a go, and just had to work out to substitute their PythonAnywhere.com deployment example, with my own server..........stuck.

I've got things working on my laptop/development environment, but the server side of things isn't behaving. I know it's to do with the MySQL config/settings/permissions/path but I can't pinpoint it.

There are so many different tutorials and commands to try, I've lost count, and so many seem to be out of date.

Then I found out about LAMP to add to my confusion, which sounds ideal if I had know about that at the start, but it doesn't include Django or Python, and I need (I think) PHP so I can use PHPMyAdmin to manage the MySQL.

Is it even possible to install LAMP on what I've already got? Would it solve the server side MySQL issue?

EDIT

I've managed to install pymysql, and when I try runserver I get a config parser error on /etc/MySQL/my.cnf from /test_blog_app/blog pip list output is below (and I have no idea what most of them are):
