Flash your keyboard by pressing the buttom on the back.
To check if it is indeed in flash mode, check it by running $ lsusb
it should show the name of the microcontroller in one of the items (in my case ATMEGA32U4)
$ sudo dfu-programmer erase atmega32u4
$sudo groupadd docker
$sudo gpasswd -a $USER docker
Either do a $newgrp docker or log out/in to activate the changes to groups.
Test it
$docker run hello-world

Because of the design used to model Redis streams, the memory usage is remarkably low. It depends on the number of fields, values, and their lengths, but for simple messages we are at a few millions of messages for every 100 MB of used memory. Moreover, the format is conceived to need very minimal serialization: the listpack blocks that are stored as radix tree nodes, have the same representation on disk and in memory, so they are trivially stored and read. For instance Redis can read 5 million entries from the RDB file in 0.3 seconds. This makes replication and persistence of streams very efficient.
It is planned to also allow deletion of items in the middle. This is only partially implemented, but the strategy is to mark entries as deleted in the entry flag, and when a given ratio between entries and deleted entires is reached, the block is rewritten to collect the garbage, and if needed it is glued to another adjacent block in o
