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.**

IP Webcam manual bulk file download

Open http://192.168.1.10:8080/videomgr.html#/modet in Firefox

F12 → Console


Add Set to remove duplicates:

[...new Set(

  [...document.querySelectorAll("a[href*='/v/modet/']")].map(a => a.href)

)].join("\n")

Explanation:

querySelectorAll → all <a>

map(a => a.href) → array of hrefs

new Set(...) → keeps only unique values

[...new Set(...)] → back to array for join("\n")


Copy output → save as list.txt

mkdir ipcam10

nano list.txt → Ctrl + Shift + V

mv list.txt ipcam10

wget -i list.txt --base=http://192.168.1.10:8080/v/modet/

Connect to Kubuntu from Android via Termux

1. Preparations on your Kubuntu 24.04 PC

    Enable Remote Desktop: Go to System Settings > System > Remote Desktop. Enable "Desktop Sharing" (VNC) or "Remote Login" (RDP).

    sudo apt update && sudo apt install openssh-server.

    To find your PC's local IP address (e.g., 192.168.1.10):

    ip addr  OR ip addr  | grep inet    

2. Installation on Termux (Android)

Install OpenSSH client to create the secure bridge:

    pkg update && pkg upgrade

    pkg install openssh

    Create the Tunnel: Use this command to forward your PC's remote desktop port to your phone.

        For RDP (Recommended): ssh -L 3389:localhost:3389 user@your_pc_ip

        For VNC: ssh -L 5901:localhost:5901 user@your_pc_ip

        (Keep this Termux session running in the background).

3. Connecting to the Desktop

Once the tunnel is active, you do not use Termux to view the screen; you use a dedicated app to connect to the "tunnel" Termux created.

    Download a Client: Install aRDP from Play Store or F-Droid.

    Configure the Connection:

        PC Name / Host: 127.0.0.1 (or localhost).

        Port: If the app asks, use 3389 (RDP) or 5901 (VNC).

    Login: Use your standard Kubuntu username and password.

If you get a black screen when connecting via RDP, ensure you are logged out of the physical PC first. Kubuntu's current RDP implementation often prevents simultaneous local and remote sessions for the same user.

SP Flash Tool segmentation fault on Kubuntu 24.04

Can't readback large ROMs from phone? Solution:

1. Disable ModemManager

Linux's ModemManager often tries to grab the phone's port because it detects a serial device (/dev/ttyACM0). This causes the connection to drop and SP Flash Tool to crash.

Temporarily stop :

    sudo systemctl stop ModemManager

    sudo systemctl disable ModemManager

2. Check udev Rules

Kubuntu needs to be told to ignore the MediaTek device to prevent the kernel from interfering.

Create a new udev rule file:

    sudo nano /etc/udev/rules.d/20-mm-blacklist-mtk.rules

Add this line to tell ModemManager to ignore your device:

    ATTRS{idVendor}=="0e8d", ENV{ID_MM_DEVICE_IGNORE}="1"

    Add another rule for user permissions:

    SUBSYSTEM=="usb", ATTR{idVendor}=="0e8d", MODE="0666"

Reload rules:

    sudo udevadm control --reload-rules

    sudo udevadm trigger
