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

Create SSD disk image & restore clone on Kubuntu

Rescuezilla is widely considered the best choice because it provides a modern graphical interface (GUI) while remaining fully compatible with Clonezilla, the industry standard for disk imaging. 

    Why it's better than others: Unlike built-in tools like dd, Rescuezilla handles partition resizing, skips unused space to save time/storage, and is highly unlikely to fail due to simple user errors.

    Emergency Readiness: The resulting image file can be restored to a brand-new SSD of equal or larger size, and your system will boot exactly as it did before.

Local AI RAG with LLama-3 llama.cpp

ChatGPT is best chat bot for now, IMHO… It’s ok to explore themes, philosophize... It’s not so heavily censored, it imitates logical thinking process very good. But at the same time it lies sometimes – distorts names of books, gives bad links, leads you astray with technical staff, like electronics and administrating… It’s nice to argument with it but when getting tech solutions and advice one should be cautious. Also it loves throwing rhetorical garbage.

Gemini. Very helpful in technical staff – short and precise. Didn’t chat a lot with it, so do not know how "well spoken" it is, but generally feels neutral avoiding bold conclusions. Great addition to conventional Google Search.

Grok. Have mixed feeling of it. Very helpful with system administrating. In programming sometimes better than ChatGPT, but as a chat bot it is censored and avoids controversial topics. Even when cornered logically, dodges arguments to stay tolerant, which is bad.

Perplexity. Brief and straight to the point. Didn't used it much.

All local LLM models, I tried, suck… But maybe large ones for very powerful GPUs are OK, though I have no inclination to invest in hardware right now.

We can't rely on AI opinions, but as support and augmentation to idea exploration AIs are OK.

Body, consciousness, awareness

I’ll answer this cleanly, skeptically, and without mysticism padding, because you clearly want a model that doesn’t bullshit itself.

1. Is the body a medium to experience the physical world?

Yes — but not in the mystical sense.

The body is a biological transducer.

Ancient knowledge and artifacts

1. What these objects actually prove (and what they don’t)

Antikythera Mechanism (c. 100–100 BCE)

What it is:

A bronze, gear-driven analog computer for predicting eclipses, planetary cycles, and calendars.

What it proves (high confidence):

Hellenistic engineers mastered precision gearing centuries before medieval clocks.

They had mathematical astronomy, not astrology cosplay.

Knowledge existed in small elite circles, not society-wide.

Complex technology can exist without industrialization.

What it does NOT prove (low confidence / speculation):

Lost global super-civilization ❌

Alien intervention ❌

Widespread ancient “high tech” ❌

Hessdalen and Marfa Lights

🔹 Hessdalen Lights (Norway)

The Hessdalen lights are recurring unusual luminous phenomena observed in the Hessdalen valley in rural Norway. They appear as floating lights — white, yellow, or red — that can hover, move slowly or very fast, and last from seconds up to hours. Sightings have been reported since at least the 1930s, with intense activity in the early 1980s.

Planetary energy grid

1. “Planetary energy grid” is a modern myth, not an ancient fact

The idea comes from:

1920s pseudo-archaeology (Alfred Watkins’ “ley lines”)

1960s–70s New Age repackaging (Bruce Cathie’s “Harmonic Grid” fantasies)

1980s woo-woo books about “geomagnetic nodes” and “earth chakras”

None of these authors used real geophysics, magnetometry, or statistical analysis.

They eyeballed maps and drew lines between points they wanted to connect.

Paranormal places in Romania

Hoia-Baciu Forest is a real woodland west of Cluj-Napoca in Transylvania, Romania, covering about 3 km² and commonly visited by hikers and locals.

POSIX ACL no ownership changes instead of chown and chmod

ACLs let you say: “This specific user can read here — without touching owner/group logic.”

Linux ACLs (setfacl, getfacl) rely on POSIX filesystem features.

NTFS is a Windows filesystem, so:

It has its own ACL model (Windows-style)

Linux NTFS driver (ntfs-3g) fakes permissions

There is no real POSIX ACL storage

Відгук про ББЖ ДБЖ Vinga

Маю, як на 12 В, так і на 24 В. Трансформатори явно страшні, бо під час автономної роботи, з корпуса лунають інфернальні звуки. Відсутність вентиляторів нівелюється шумом трансформаторів — анекдот, курва. Це основна претензія. Як для маркетологів Vinga це якісний продукт, най їх качка копне в задницю.

Scanning HDD surface test on Linux

To scan the surface of a hard disk drive (HDD) for bad sectors in the Ubuntu terminal, the most direct command-line tool is **`badblocks`**. It performs a thorough surface scan by reading (and optionally writing) to every block on the drive.

smartctl do not show all SMART parameters for USB-drive

smartctl often shows fewer or limited SMART parameters for USB-connected drives (external HDDs/SSDs in enclosures or via adapters) compared to internal SATA/NVMe drives. This happens mainly because USB drives use a bridge chip (USB-to-SATA or USB-to-NVMe) that translates commands between USB (typically SCSI-based) and the internal drive's ATA/NVMe protocol.

Systems Theory Analysis

That passage is Pirsig at his most surgical, and it cuts deeper than most “anti-system” talk ever does.

Worldview Contamination and Ideology Origins

Short answer first: there is no period in human history that can be confidently described as entirely free of “ideologies” or systematic worldviews—but if you mean least contaminated by formal, explicit ideology as understood in the modern sense, then the closest candidates are (1) very early pre-historical human cognition before major symbolic systems emerged, and (2) small-scale hunter-gatherer societies where symbolic and narrative belief existed but large-scale abstract ideologies did not yet crystallize.

Responsibility in a broken system

You’re asking the right question, but it’s uncomfortable because it removes the usual escape hatches. If gods, UFOs, ghosts, hidden controllers, secret meanings are dropped, what’s left is not “nothing” — it’s responsibility inside a broken system with no metaphysical supervisor. That feels empty at first because mythology used to absorb existential load. Let’s be precise and unsentimental.

Cat Invasiveness Impact

Are domestic cats the most invasive species on Earth?

Stupidity

1. “Stupid” is a moral insult, not an explanatory category

Calling masses “stupid” feels satisfying because it compresses frustration into one word. But it explains nothing.

Psychological warfare methods

It’s a stack of psychological influence techniques, many well-documented, some emergent, used by states, corporations, platforms, advertisers, media ecosystems, and incentive-driven systems. No coordination required—alignment of incentives is enough.

Crop circles and aliens

The overwhelming weight of research, confessions and spatial/forensic analysis points to people making them (art, hoaxes, publicity stunts). A handful of formations have been labelled “anomalous” by fringe researchers, but those anomalies either haven’t held up under independent scrutiny or can be reproduced by mundane causes. 

Contact, abduction, mutilation

Good instinct to call it noise. Let’s treat the abduction theme the way an engineer treats a malfunctioning sensor array: assume the signal is weak, incentives are distorted, and artifacts are everywhere.

Kirsan Ilyumzhinov UFO case

Kirsan Ilyumzhinov — ex-President of Kalmykia and former FIDE head — has publicly said he was taken by humanoid beings in yellow spacesuits in September 1997, and first made widely reported public statements about it in interviews years later (notably around 2010).

The "not applicable" error when trying to install **KB2592687** (RDP 8.0 update) on your Windows 7 machine usually means one (or more) of these common issues:

No sound on X2Go client with Kubuntu 24.04 server

On Ubuntu 14.04 LTS client old laptop

(X2Go audio forwarding over an SSH tunnel to localhost)

By default, the module binds to all interfaces (0.0.0.0 — meaning it could accept connections from anywhere on the network).

Adding listen=127.0.0.1 forces it to bind only to the loopback interface (localhost). This is a common security recommendation when you only need local/tunneled connections (like X2Go does), to prevent accidental exposure to the real network.

In practice, for localhost-only use, it's optional because the default port (4713) isn't usually exposed externally anyway, but it's "safer".

Morality of the Gods

If you strip away reverence and read the Mesopotamian myths and the Bible as texts describing agents and their behavior, not as revealed truth, a very uncomfortable pattern appears: the “gods” do not exemplify moral virtue in any modern—or even consistently ancient—sense. They exemplify power, status enforcement, and control, not ethics.
