Create SSH Key on Mac for Xcode

The docs for GitHub show a command to create a key with the ed25519 encryption method which is not allowed by Xcode. Even if you are not using the Source Control features in Xcode you will often need to use an account with GitHub when you are consuming Swift packages which are pulled from GitHub.

For SSH keys there are 4 algorithms.

🚨 DSA: This is an older algorithm which is no longer supported and is superceded with more modern algorithms.
⚠️ RSA: This algorithm was an improvement but it is now outdated and a more modern method should be used.
👀 ECDSA: Another improvement which is dependent on your computer's ability to generate random numbers.
✅ Ed25519: The most recommended public-key algorithm today which you should use with GitHub.

How to create bootable USB flash drive to install Windows 10

Here are the steps to use the Media Creation Tool and Rufus to create a Windows 10 bootable media.

You can create a Windows 10 USB installation media with multiple tools, and in this guide, we'll show you how. When a new version of Windows 10 becomes available, not everyone gets the latest release the same day. Instead, Microsoft upgrades computers gradually, and it takes some time until the new version reaches every device.

However, if you do not want to wait for the automatic upgrade, the company lets you download the Windows 10 installation files using the Media Creation Tool. The tool helps perform an in-place upgrade or create an installation media using a USB f

One-liner to convert all FLAC to MP3

find "[MP3]"* -name "*.flac" -exec bash -c 'ffmpeg -i "${0}" -ab 320k -c:v copy "${0/.flac/.mp3}" && rm "${0}"' {} \;

I prefer to duplicate my .flac files before ffmpeg-ing them all, hence the "[MP3]"* prefix on the find and the rm at the end. Sometimes, this may be unnecessary, since I might put the MP3 files in their own subdirectory, at which point find . will work fine. In the case this example is pulled from, I had two [MP3] folders and two [FLAC] folders in the same directory.

#! /usr/bin/env nix-shell #! nix-shell -i bash -p ffmpeg_5

trap 'echo "Aborting..."; exit 1' SIGINT

find . -type f -name "*.flac" -print0 | while read -d $'\0' flac_file; do echo "Input file: $flac_file" mp3_file="${flac_file%.flac}.mp3" ffmpeg -nostats -loglevel 0 -nostdin -i "$flac_file" -vn -b:a 320k -acodec libmp3lame "$mp3_file" || { rm "$mp3_file"; exit; }; rm "$flac_file"
