                                     (and probably others GL-Inet routers from 2022)

I don't like this, do you?

This routers has two web interfaces, GL-Inet interface and Luci (standard OpenWrt interface). So let's start.

From @BalCC0n orga team for hackers communities

People from our team have PC Engine small single board computers for networking in their office or home office. To protect board we are using this case:

The heat spreader kit is included with apu boards but because of his size it's not really easy to place it where we want. People from PC Engine are selling heat spreader placement fixture (apufix1a https://pcengines.ch/apufix1a.htm)), but in some countries is not even possible to order it.

Hi folks,

For some time now there is an issue for all people running VMWARE Workstation (i think even player) with vmmon and vmnet kernel modules. When you start Workstation you will get message "Before you can run VMWare, several modules must be compiled and loaded into the running kernel". You will try to click on install, but in the end you will get an error message with path to error log file.

I'm running kernel 5.4 because this version is fixing few hardware issues I have with "modern hardware" on my laptop.
