AzCopy is a useful tool for data operations between servers and Azure Cloud Storage. However, by default, this tool cannot be used on servers with less than 1GB of memory. To resolve this issue, some parameters need to be configured.

Try to set

export AZCOPY_CONCURRENCY_VALUE=1
export AZCOPY_CONCURRENT_SCAN=1
export AZCOPY_BUFFER_GB=0.12

Values can be changed based on your system configuration.

Sometimes, especially if the link to LFS is broken or the repository has been moved, it becomes necessary to clone the repository while ignoring LFS.

For clone repository without LFS in Linux need to add GIT_LFS_SKIP_SMUDGE=1 before git clone command.
Example: GIT_LFS_SKIP_SMUDGE=1 git clone your_repository

For Windows in PowerShell: $env:GIT_LFS_SKIP_SMUDGE=1 git clone your_repository

For fix error ImportError: no module named 'ssd1306'  you should download ssd1306.py library from official micropython repository for libraries – micropython/micropython-lib on GitHub https://github.com/micropython/micropython-lib and copy using pyboard tool.
Direct link on this library https://github.com/micropython/micropython-lib/blob/master/micropython/drivers/display/ssd1306/ssd1306.py

Steps:
1. Download library https://github.com/micropython/micropython-lib/blob/master/micropython/drivers/display/ssd1306/ssd1306.py
2. Use pyboard tool https://docs.micropython.org/en/latest/reference/pyboard.py.html for copy this file (ssd1306.py) on root folder on the board.
3. Try to run import ssd1306

FUSE is a Filesystem in Userspace that allows the creation of custom filesystems in userspace, such as cloud storage, NFS and etc. But for mount inside docker container need to add additional parameters to docker run command or inside docker-compose.yml file.

At first, you should have docker image with installed fuse package inside container. For allow mount inside container need to run docker run command with --cap-add SYS_ADMIN --device /dev/fuse:/dev/fuse --security-opt apparmor:unconfined

For docker-compose need to put inside docker-compose.yml file: 

cap_add:
  - SYS_ADMIN
devices:
  - /dev/fuse:/dev/fuse
security_opt:
  - apparmor:unconfined


Examples:

• Docker: docker run -it --rm --cap-add SYS_ADMIN --device /dev/fuse:/dev/fuse --security-opt apparmor:unconfined
• docker-compose.yml:
  version: '3'
services:
mycontainer:
  image: container_image:container_version
  cap_add:
    - SYS_ADMIN
  devices:
    - /dev/fuse:/dev/fuse
  security_opt:
    - apparmor:unconfined

Nowadays, power banks are becoming increasingly popular as people rely on their devices (such as mobile phones, laptops, cameras and etc) for work, entertainment, and communication.

But sometimes power bank with displays doesn’t work and have “188 error” – power bank screen flashing all numbers “188”. In most of cases this error caused by complex power bank malfunction that can be fixed only in service center or as a result of internal power bank protection circuit (for example, overload, short circuit and etc).

In some of cases you can restore power bank by reset – press power bank button on 5,10,15 or 20 seconds for reset. Also you can try to search using sentence “power bank your_powerbank_manufacter how to reset”.

If it doesn’t help or have another error – in this case only service center can do repair. If you still have warranty it can be case that will be covered free by warranty.
