The ffmpeg command
ffmpeg -y -r 30 -i in_%05d.jpg -i ../NormPeak-6dBENG.wav -c:v hevc_nvenc -preset lossless -global_quality 18 -pix_fmt nv12 -c:a aac -b:a 192k ~/Downloads/4kframes.mp4
gives the following warnings -
[aist#1:0/pcm_s16le @ 0x59f7e96fbfc0] Guessed Channel Layout: stereo
....

Claude's suggestion to fix -
ffmpeg -y -r 30 -i in_%05d.jpg -thread_queue_size 512 -i ../NormPeak-6dBENG.wav -c:v hevc_nvenc -preset p7 -tune lossless -cq 0 -pix_fmt yuv420p -c:a aac -b:a 192k ~/Downloads/4kframes.mp4
PB helped me out with the following info:
From ChatGPT,
ffmpeg -i filename_%05d.jpg -c:v hevc_qsv -preset veryslow -global_quality 0 output_lossless_qsv.mkv
With audio, we would need something like
ffmpeg -r 30 -i KG-LS_%05d.jpg -i audio.wav \
-c:v hevc_qsv -preset veryslow -global_quality 0 \
-c:a aac -b:a 192k \
-shortest \
output_with_audio.mkv
# or on Windows,
ffmpeg -r 30 -i KG-LS_%05d.jpg -i audio.wav ^
-c:v hevc_qsv -preset veryslow -global_quality 0 ^
-c:a aac -b:a 192k ^
-shortest ^

According to this youtube video, there are some terms and conditions which are shown only in the Airtel app, by which

sudo dd if='/path/to/linuxmint-22-cinnamon-64bit.iso' of=/dev/sdd bs=4M status=progress
2810183680 bytes (2.8 GB, 2.6 GiB) copied, 140 s, 20.1 MB/s
So, on my machine, it took less than three minutes to create a 2.8 GB boot disk.
Asked ChatGPT, "linux commandline to list total disk space used of all files created or modified inside a directory more than one year ago" and got the following -
You can do this with find + du or find + stat + awk.
Here’s a one-liner that lists the total disk space used by files in a directory older than one year:
find /path/to/dir -type f -mtime +365 -printf "%s\n" | \
awk '{sum+=$1} END {print sum/1024/1024 " MB"}'
find /path/to/dir → search inside that directory.
-type f → only files.
-mtime +365 → modified more than 365 days ago (roughly one year).
-printf "%s\n" → print file sizes in bytes.
awk → sums up sizes and prints total in MB (divide by 1024/1024).
If you prefer human-readable output directly:
find /path/to/dir -type f -mtime +365 -print0 | du --files0-from=- -ch | tail -n1
This gives you a total in du’s human-readable format.
Asked ChatGPT, "tree view of files and directories larger than 1 GB from linux command line" and got the following -
You can combine find, du, and tree-style output to list only files/directories larger than 1 GB in a tree view. Here are a couple of approaches:
find with treefind /path/to/search -type f -size +1G -print | tree --fromfile
find ... -size +1G → finds files > 1 GB
tree --fromfile → prints a tree structure from the list
If you want directories too (based on contents size), use du instead (see below).
du for directories/files with sizesdu -h --threshold=1G --max-depth=3 /path/to/search | sort -h
--threshold=1G → only show entries larger than 1 GB
--max-depth=3 → how deep to go
sort -h → human-readable sort
This shows sizes and paths (not tree formatting, but size summary is clearer).
dudu -h --threshold=1G --max-depth=3 /path/to/search | sort -hr |
awk '{print $2}' | tree --fromfile
This gives you a tree structure of directories/files whose total size is ≥ 1 GB.
✅ If you want only the largest offenders (say top 20 big files/directories over 1 GB), you can do:
find /path/to/search -type f -size +1G -exec du -h {} + | sort -hr | head -20
For this, I had to sudo apt install tree
How to use github projects - a getting started video -
https://www.youtube.com/watch?v=oPQgFxHcjAw
Opened a private repo with issues, and with ChatGPT's help, linked it to a project. (Projects --> New Project in the github web UI for that repo). Automation to create a new issue worked after some tweaking - the github actions yml is copy-pasted below:

This script had to be re-written due to ChatGPT repeatedly using heredoc syntax which would clash with github's yml. I had to explicitly ask it to "Please use echo >> on each line, and no heredoc."
One more automation script to automatically move the items in the project from "TODO" to "In Progress" when any of the checkboxes above were clicked, failed. ChatGPT usually fails when the documentation is not complete and / or there are conflicting earlier documentation pages, as in this case. It would repeatedly suggest using
permissions: issues: write projects: write
when actually such a permission is no longer accepted by Github - it was part of "classic projects" - https://docs.github.com/en/enterprise-server@3.16/issues/planning-and-tracking-with-projects/creating-projects/migrating-from-projects-classic.
Apparently with projectsV2, the REST api does not work, only GraphQL API works. And it needs a classic personal access token to work. And the code generated by ChatGPT had errors which I could not get it to fix after multiple iterations over multiple days, so I just left updates to be done manually by clicking on the drop-down seen in the linked project for each issue. I could probably read the GraphQL API documentation and try again, but right now, not motivated to do so.
After a cloudflare advisory asking us to rotate credentials due to a "Compromise Impacting Cloudflare Salesforce Cases", I was asked to force 2FA for all cloudflare users.

The force-2FA option is available for super-admins in the cloudflare admin panel, at
