Sound Selector for MacOS

on MacOS, you can switch the input and output source on “system setting/sound”. i’d like todo this on the cli.

SwitchAudio

there is a litte tool called switchaudio. it can list, and also set the input/output device. let’s build a small wrapper around.

brew install switchaudio-osx

Usage

List Sound Devices

stoege@mac ~ % sound.sh

1: Externe Kopfhörer
2: Externes Mikrofon
3: Jabra Link 400
4: Mac mini-Lautsprecher
5: SRS-XB33
6: USB Audio Device

Intro

hdiutil is a command-line utility on macOS that allows users to create, manipulate, and convert disk images. Disk images are virtual disk files that can contain the entire file system structure, including files, folders, and metadata. hdiutil provides a variety of functions related to disk images, and it’s a powerful tool for managing disk-related tasks on a Mac.

Basic Usage

create

echo -n "geheim" |hdiutil create -encryption -stdinpass -size 10m -volname encdata test.dmg -fs HFS+J

mount ro

echo -n "geheim" |hdiutil mount -stdinpass -readonly test.dmg

mount rw

echo -n "geheim" |hdiutil mount -stdinpass test.dmg

create, strong, mount

echo -n "geheim" |hdiutil create -encryption AES-256 -stdinpass -attach -volname encdata -size 10m test.dmg -fs HFS+J

unmount

hdiutil unmount /Volumes/encdata

Monaspace

Do you like it ? I do …

Install macOS

brew tap homebrew/cask-fonts
brew install font-monaspace

Running a WebApp in 5min ?

ASP.NET Tutorial - Hello World in 5 minutes

in a Language you never touched before … ? a Microsoft App running on Linux running in Docker running on macOS … ?

Let’ give a try …

Fireup Ubuntu via Docker, do Port Forward

docker run -it -p 5123:5123 --name dotnet-hello ubuntu:latest

add basics

apt-get update && apt-get -y upgrade && apt-get -y install wget

add dotnet

wget https://packages.microsoft.com/config/ubuntu/22.10/packages-microsoft-prod.deb -O packages-microsoft-prod.deb
dpkg -i packages-microsoft-prod.deb && rm packages-microsoft-prod.deb
apt-get update && apt-get install -y dotnet-sdk-7.0
dotnet --version

build webapp

dotnet new webapp -o MyWebApp --no-https -f net7.0

run webapp, change IP & Port

cd MyWebApp
sed -i 's#"applicationUrl".*#"applicationUrl": "http://0.0.0.0:5123",#' Properties/launchSettings.json
dotnet watch
