Disabling power button on Windows 10
When you mistakenly press power button your Windows 10 machine surprisingly shuts down. Switch it off with the following steps:
Compiling Awl on Ubuntu 18 and 20 with GCC 11
Below I provided the instruction on how to build Awl on Ubuntu 18 and 20.
On Ubuntu 18 you do an extra step to install CMake version >= 3.12:
wget -O - https://apt.kitware.com/keys/kitware-archive-latest.asc 2>/dev/null | sudo apt-key add -
sudo apt-add-repository 'deb https://apt.kitware.com/ubuntu/ bionic main'
sudo apt update
Then do the following steps on both Ubuntu 18 and 20:
sudo apt install cmake
cmake --version
Built my QT app for Android with API level 30 (Android 11)
New Android App Bundle and target API level requirements in 2021:
Starting August 2021, new apps will be required to target API level 30 (Android 11) and use the Android App Bundle publishing format. Starting November 2021, all app updates will be required to target API level 30 (Android 11). Apps with a download size of more than 150 MB are now supported by Play Asset Delivery and Play Feature Delivery.
I updated the manifest manually as follows:
<?xml version="1.0"?>
<manifest package="net.geographx.LinesGame" xmlns:android="http://schemas.android.com/apk/res/android" android:versionName="2.5.30" android:versionCode="161" android:installLocation="auto">
<uses-sdk android:minSdkVersion="21" android:targetSdkVersion="30"/>
My QT Android app periodically crashes at android::RefBase::incStrong(void const*)
The call stack is:

It is a QT bug that is not fixed yet.
Also my app crashes at the destructor of std::thread and this also a QT bug that is not fixed yet.
Building QT 6.1.0 for Android on Windows
Theoretically it can be:
git clone --recursive https://code.qt.io/qt/qt5.git --branch v6.1.0
or alternatively:
git clone https://code.qt.io/qt/qt5.git --branch v6.1.0
./init-repository --branch --module-subset=essential,qtandroidextras,qtsvg,qtquickcontrols2,qtgraphicaleffects,qtwebsockets,qtmultimedia
or
./init-repository --module-subset=all

Mining Chia cryptocurrency on Windows 10
I bought a 6TB HDD for 19 990 rubles (in Russia) and started to mine Chia cryptocurrency on my Windows 10 machine using existing 500GB SSD as a temporary space. Now it is building the plots:
Error reading file: No space left on device
I had a large SQLite file C:\Users\D-Ef\AppData\Local\TradeClient\realtime.db that I was unable to copy to another disk. I tried:
split -n 10 -d -u realtime.db /mnt/d/db/rt
dd bs=65536 if=realtime.db of=/mnt/d/db/rt
in WSL, but got ‘error reading ‘realtime.db’: No space left on device’ with all the commands.
Finally I reduced page file size restarted my machine and copied the file in a usual way.
