Unlike purely AI-generated content, NGC explicitly recognizes the human brain as an active co-creator in the generative process, establishing a hybrid authorship model. Key Principles 1.

Abstract In modern computing, containerization has revolutionized how we build, deploy, and isolate software systems. Technologies like Docker and Kubernetes introduced a new paradigm — lightweight, isolated environments that share a host’s resources while remaining secure, reproducible, and independent. But what if we could extend that same principle into the physical world?https://sekor.eu.org/note/piper-tts-onnx/Tue, 23 Sep 2025 07:31:21 +0000https://sekor.eu.org/note/piper-tts-onnx/download piper-voices: https://huggingface.co/rhasspy/piper-voices/ ls ~/.config/speech-dispatcher/voices/ de_DE-thorsten-high.onnx de_DE-thorsten-medium.onnx.json en_US-lessac-low.onnx en_US-ryan-medium.onnx.json pl_PL-gosia-medium.onnx de_DE-thorsten-high.onnx.json en_US-amy-medium.onnx en_US-lessac-low.onnx.json pl_PL-darkman-medium.onnx pl_PL-gosia-medium.onnx.json de_DE-thorsten-medium.onnx en_US-amy-medium.onnx.json en_US-ryan-medium.onnx pl_PL-darkman-medium.onnx.json # cat ~/.config/speech-dispatcher/speechd.conf AddModule "piper-tts-generic" "sd_generic" "piper-tts-generic.conf" DefaultModule piper-tts-generic # cat ~/.config/speech-dispatcher/modules/piper-tts-generic.conf GenericExecuteSynth "echo \"$DATA\" | piper-tts --model /home/mod/.config/speech-dispatcher/voices/$VOICE--output_raw -f - | mpv --no-terminal --keep-open=no -" GenericLanguage "pl" "pl" "UTF-8" GenericLanguage "de" "de" "UTF-8" GenericLanguage "en" "en" "UTF-8" AddVoice "pl" "female1" "pl_PL-gosia-medium.onnx" AddVoice "pl" "male1" "pl_PL-darkman-medium.onnx" AddVoice "en" "female1" "en_US-lessac-low.onnx" AddVoice "en" "male1" "en_US-ryan-medium.https://sekor.eu.org/note/protect-forgejo-anubis-nginx/Sun, 21 Sep 2025 08:34:05 +0200https://sekor.eu.org/note/protect-forgejo-anubis-nginx/pacman -S anubis cp /usr/share/doc/anubis/data/botPolicies.yaml /etc/anubis/gitea.botPolicies.yaml cp /etc/anubis/default.env /etc/anubis/forgejo.env cat /etc/anubis/forgejo.env BIND=:8923 DIFFICULTY=4 METRICS_BIND=:9090 SERVE_ROBOTS_TXT=0 TARGET=http://localhost:3025 # forgejo port systemctl enable --now anubis@forgejo.service # cat /etc/nginx/sites-enabled/git.sekor.eu.org.conf server { listen 80; listen [::]:80; server_name git.sekor.eu.org; location / { return 301 https://$host$request_uri; } } server { listen 443 ssl http2; listen [::]:443 ssl http2; server_name git.sekor.eu.org; ssl_certificate /etc/letsencrypt/live/sekor.eu.org/fullchain.pem; ssl_certificate_key /etc/letsencrypt/live/sekor.eu.org/privkey.pem; location / { #proxy_pass http://127.0.0.1:3025; proxy_pass http://127.0.0.1:8923; # anubis reverse proxy proxy_set_header Connection $http_connection; proxy_set_header Upgrade $http_upgrade; proxy_set_header Host $host; proxy_set_header X-Real-IP $remote_addr; proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; proxy_set_header X-Forwarded-Proto $scheme; proxy_set_header X-Http-Version $server_protocol; client_max_body_size 512M; } } systemctl restart anubis@forgejo.https://sekor.eu.org/note/macos-like-open-for-linux/Tue, 21 Jan 2025 09:04:53 +0000https://sekor.eu.org/note/macos-like-open-for-linux/One thing I enjoy on my work Mac is the ‘open’ command.

Obejmuje to trudności w zakresie świadomości fonologicznej, dekodowania fonologicznego, szybkości przetwarzania, kodowania ortograficznego, słuchowej pamięci krótkotrwałej, umiejętności językowych/zrozumienia słownego i/lub szybkiego nazywania.https://sekor.eu.org/techlog/radio-station-with-rds-function-on-raspberry-pi/Mon, 04 Sep 2017 01:18:06 +0200https://sekor.eu.org/techlog/radio-station-with-rds-function-on-raspberry-pi/Today I will demonstrate you how to install the FM radio transmitter on Raspberry Pi. It is not just a transmitter! It supports RDS function with all its options (PS, RT, TA/TP). So do it! The only thing we need to know is that the transmitter needs an antenna. Of course, you can broadcast from GPIO goldpin, but the range of such a solution is barely a few meters. Simply attach the short cables to the GPIO4 (4 pin inside) to extend the range up to a hundred meters.https://sekor.eu.org/techlog/convert-mercurial-project-to-git/Mon, 28 Aug 2017 04:35:53 +0200https://sekor.eu.org/techlog/convert-mercurial-project-to-git/I’m using fast-export: cd ~ git clone https://github.com/frej/fast-export.git git init git_repo cd git_repo ~/fast-export/hg-fast-export.sh -r /path/to/old/mercurial_repo git checkout HEAD source: https://stackoverflow.com/questions/16037787/convert-mercurial-project-to-githttps://sekor.eu.org/techlog/simple-start-with-yolo-v2/Tue, 22 Aug 2017 17:14:30 +0200https://sekor.eu.org/techlog/simple-start-with-yolo-v2/reduce frames to 15 per sec: # ffmpeg -i stepup.mp4 -r 15 stepup15.mp4 make new directory for frames and put to stepup/ a video to split #mkdir stepup/; mkdir yolo_stepup/ split to frames: # ffmpeg -i stepup15.mp4 stepup_%04d.png lets begin the games! run this script, make sure are you not in stepup/, you shold be in darknet/ #!/bin/bash for file in stepup/*.png do ./darknet detect cfg/yolo.cfg cfg/yolo.weights "$file" mv predictions.https://sekor.eu.org/techlog/useful-keyboard-shortcuts-for-terminal/Mon, 10 Jul 2017 16:42:08 +0200https://sekor.eu.org/techlog/useful-keyboard-shortcuts-for-terminal/Terminal clipboard, check it out :) ctrl + u = Cut to the clipboard ctrl + y = Paste from the clipboardhttps://sekor.eu.org/techlog/debian-9-change-the-network-from-enp3s0-to-eth0/Wed, 05 Jul 2017 16:17:32 +0200https://sekor.eu.org/techlog/debian-9-change-the-network-from-enp3s0-to-eth0/nano /etc/udev/rules.d/10-network.rules SUBSYSTEM=="net", ACTION=="add", ATTR{address}=="08:00:27:a6:ad:0e", NAME="eth0" SUBSYSTEM=="net", ACTION=="add", ATTR{address}=="08:00:27:6e:77:cc", NAME="wlan0" then reboot.https://sekor.eu.org/techlog/1998-vs-2017/Sat, 01 Jul 2017 14:53:46 +0200https://sekor.eu.org/techlog/1998-vs-2017/1998: Don’t get into strangers’s cars Don’t meet people from the internet 2017: Literally summon strangers from the internet to get into their carhttps://sekor.eu.org/techlog/quick-way-to-add-new-posts-in-jekyll-with-python/Sat, 01 Jul 2017 00:54:18 +0200https://sekor.eu.org/techlog/quick-way-to-add-new-posts-in-jekyll-with-python/To make life a little easier from datetime import datetime MYPOST = """\ --- layout: post title: "{0}" date: {1} +0200 categories: {2} --- here my text """ if __name__ == "__main__": title = raw_input("Title:\n") categories = raw_input("Categories:\n") if not categories: categories = "posts" timestamp = datetime.today().strftime("%Y-%m-%d%H:%M:%S") datestamp = datetime.today().strftime("%Y-%m-%d") filename = datestamp + "-" + "-".join(title.split(" ")) + ".md" filename = filename.lower() with open(filename, "w+") as file: file.write(MYPOST.format(title, timestamp, categories))https://sekor.eu.org/techlog/mark-zuckerberg-says-facebook-has-2-billion-people/Wed, 28 Jun 2017 14:10:58 +0200https://sekor.eu.org/techlog/mark-zuckerberg-says-facebook-has-2-billion-people/Mark Zuckerberg officially announced that over 2 billion people in the world have a Facebook account As of this morning, the Facebook community is now officially 2 billion people!
