At least 16GB unified memory for Gemma 4 (default 8B)
macOS with Homebrew installed

1. Copy m3u8 link

2. Run command

echo "Enter m3u8 link:";read link;echo "Enter output filename:";read filename;ffmpeg -i "$link" -bsf:a aac_adtstoasc -vcodec copy -c copy -crf 50 $filename.mp4

RIR Delegations

These pages provide statistics on IP addresses and ASN numbers delegated by RIRs to each country in their geographic area. Delegation details for each country are also available.

These statistics are generated automatically from the RIRs delegation files available via FTP:

Demystifying Docker Volumes for Mac and PC Users

Docker runs on a Linux kernel

Docker can be confusing to PC and Windows users because many tutorials on that topic assume you're using a Linux machine.

As a Linux user, you learn that Volumes are stored in a part of the host filesystem managed by Docker, and that is /var/lib/docker/volumes. When you're running Docker on a Windows or Mac OS machine, you will read the same documentation and instructions but feel frustrated as that path don't exist on your system. This simple note is my answer to that.

When you use Docker on a Windows PC, you're typically doing one of these two things:

Run Linux containers in a full Linux VM (what Docker typically does today)

iptables n'at

Source NAT

Source NAT changes the source address in IP header of a packet. It may also change the source port in the TCP/UDP headers. The typical usage is to change the a private (rfc1918) address/port into a public address/port for packets leaving your network. Available only in the POSTROUTING chain in iptables.

Syntax

iptables -t nat -A POSTROUTING -i eth1 -j SNAT --to-source 1.2.3.4[:port]

My feeble attempt to organize (in a somewhat logical fashion) the vast amount of information, tools, resources, tip and tricks surrounding penetration testing, vulnerability assessment, and information security as a whole*

	This file remaps the key bindings of a single user on Mac OS X 10.5 to more
	closely match default behavior on Windows systems. This makes the Command key
	behave like Windows Control key. To use Control instead of Command, either swap
	Control and Command in Apple->System Preferences->Keyboard->Modifier Keys...
	or replace @ with ^ in this file.

	Here is a rough cheatsheet for syntax.
