KGet download and upload limit not working

nano ~/.bashrc

alias slowget='aria2c -c -x 16 -s 16 --file-allocation=prealloc --max-download-limit=1024K -o'

source ~/.bashrc

cd /desired/folder

slowget "file_0.avi" "URL"

If download fails:

slowget "file_0.avi" "NEW_URL" // to resume

Alternatives for using KGet:

E: Package 'trickle' has no installation candidate

sudo apt install firejail // 28.5 MB

firejail --net=eth0 --bandwidth=kget:1500:1500 kget

sudo wondershaper eth0 1500 1500 // NIC limit

GA-970A-DS3P FX wake on lan not working on Lubuntu

Looks like WOL is Enabled by default, if Erp Disabled, and MB is made solely for Windows, where WOL is enabled in driver. Enabled Power On By Mouse, Power On By Keyboard just in case... No lights on LAN port but 2.5W power draw... If CPU Turbo mode is enabled, 3.5W power draw...

nmcli connection show

sudo nmcli connection modify "Wired connection 1" 802-3-ethernet.wake-on-lan magic

Alternatives:

Option A — NetworkManager

Create a dispatcher script:

sudo nano /etc/NetworkManager/dispatcher.d/99-wol

Put:

#!/bin/sh

ethtool -s eth0 wol g

Make executable:

sudo chmod +x /etc/NetworkManager/dispatcher.d/99-wol

Reboot and check:

ethtool eth0 | grep Wake

Option B — systemd service

sudo nano /etc/systemd/system/wol.service

No truth - just approximation

What we’ve been circling around is **not new at all**. Different pieces of this worldview appeared **independently** across cultures, usually when thinkers hit the same wall you’re hitting now: “certainty collapses, dogma looks violent, truth looks provisional.”

Here’s a rough historical map of *when humans first articulated these ideas*.

Worst Human Dogmas

### 1. **“My group is chosen / superior / righteous”**

The nuclear reactor of evil.

* Justifies genocide, slavery, crusades, purges, and ethnic cleansing.

* Turns neighbors into “less than human.”

* Works with religion, race, nation, class, or ideology.

  **Body count: maximal.**
