How to update the Go version

System: Debian/Ubuntu/Fedora. Might work for others as well.

1. Uninstall the exisiting version

As mentioned here, to update a go version you will first need to uninstall the original version.

Правила компоновки во Flutter, которые должен знать каждый

Когда новичок во Flutter спрашивает, почему какой-то виджет с width: 100 не ширины 100 пикселей, обычно ему отвечают, что надо обернуть этот виджет в Center, верно?

Не надо так делать

Если так отвечать, то к вам будут возвращаться снова и снова, спрашивая, почему какой-то FittedBox не работает, почему этот Column переполнен или как работает IntrinsicWidth.

Сначала объясните, что Flutter компоновка очень отличается от HTML компоновки (особенно, если говорите с веб-разработчиком), а затем скажите, что необходимо запомнить следующее правило:

Make sure the if value is correct! If doing this over SSH then open a TMUX session first... or else...

dd if=/dev/YOUR-DEVICE conv=sync,noerror bs=64K | gzip -c  > /home/portaj/macbook.img.gz

NOTE: You might not want to compress the image. It just means you have to uncompress it later to mount it. If you're planning to access the data soon, or frequently, don't compress it.

Saving a copy of the drive geometry

Save it in the same directory as the compressed image so later on if you decide you want to mount or extract data from the image you can see the partition structure without having to decompress the whole image. There might be some other ways to mount a compressed image.
