                                 Fixing the broken SSL security in the GL-MT3000 routers
                                     (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.

myaddr.tools

A minimalist dynamic DNS service

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.

	#!/bin/bash

	# This script will extract the certificate and key from an .ovpn file
	# into their own files, which makes it possible to use them to configure
	# the VPN using Ubuntu's network manager

	# Usage example:
	# >> ovpnconvert username.dev.ovpn

	sed '1,/<ca>/d;/<\/ca>/,$d' $1 > $1.ca.crt

	I woke up, started my laptop, and I got laptop poweroff just after booting. My Carbon X1 (7th generation) is only 2 months
	old. Not really best way to start a day.

	Solution:

	1. Power off your lap top
	2. Find this little reset button on the bottom of your laptop
	3. Hold for five seconds let go; plug laptop back
	4. Hit power button

	## Install VMWare Player 15.5 for Ubuntu 18.04 and BakcBox Linux

	I don't know if VMWare is messing with Linux users or they just don't care, installing VMWare player was not pleasure at all.
	You need hackish brain to make it working with Remove Console who is kind of dependency for VMWare WebSphere and
	advanced users of VMWare products. Anyway ..

	## Step by step

	Install older version of VMWare Player 12.5.9

	THIS IS OLD VERSION NOT SUPPORTED ANYMORE
