OSX improved (Update)

Updated May 17, 2024 to fit M* architecture

My favorite development environment on my MacBook includes an improved Zsh shell and an extended .vimrc configuration file with syntax highlighting, error checking, TextMate snippets, and the Solarized color scheme. 

Here's a guide for setting up similar features:  The features include directional key navigation for directories and files, developer-friendly colors, command highlighting, improved history search, auto-complete for options and SSH connections (if keys are known), and many more useful enhancements.  

Get Xcode:
 AppStore => Xcode => Install Xcode

From now we use a terminal window.

Install Brew
/usr/bin/ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"

Install git and wget:
 brew install git
 brew install wget


Install oh-my-zsh:
 wget --no-check-certificate https://github.com/robbyrussell/oh-my-zsh/raw/master/tools/install.sh -O - | sh

The script want to change your shell from /bin/bash into /bin/zsh, here you have to provide your password.

To change the theme edit ~/.zshrc and edit line 8:
 ZSH_THEME="YOUR_FAV_THEME"

Install and enable zsh-highlighting:
 git clone https://github.com/zsh-users/zsh-syntax-highlighting.git ~/.oh-my-zsh/plugins/
 edit .zshrc and add in line 27 (space separated):
  zsh-syntax-highlighting

Solarized and Pathogen
(https://ethanschoonover.com/solarized)
(https://github.com/tpope/vim-pathogen)

mkdir -p ~/.vim/autoload ~/.vim/bundle; \  
curl -so ~/.vim/autoload/pathogen.vim \
    https://raw.github.com/tpope/vim-pathogen/HEAD/autoload/pathogen.vim

 
cd ~/.vim/bundle
 git clone https://github.com/altercation/vim-colors-solarized.git


Extended .vimrc:
cd ~/ && git clone https://github.com/ikaros/vim-configuration.git && rm -rf .vim && mv vim-configuration .vim && rake -T && rake place_vim_config

I remove some bundles for now:
 git rm --cache bundle/cucumber
 git rm --cache bundle/rubytest
 git rm --cache bundle/snipmate

and add snipmate, because the bundle above does not work:
 git submodule add https://github.com/msanders/snipmate.vim.git bundle/snipmate

update all bundles:
 git submodule update --init

To change the Solarized theme edit in your .vimrc the background-variable (set background=light | dark)

Finished. Enjoy your new shell!

Coding languages

Rust:
curl –proto ‘=https’ –tlsv1.2 -sSf https://sh.rustup.rs | sh

Golang: 
Download the binaries from https://go.dev/dl/
Sometimes I got into some trouble installing / updating Go, here's snippets to do so:
https://gist.github.com/gsrai/09bfc7db6548aecfbeacdcd89dcd0720

Additional tools I recommend

iTerm (terminal replacement)
VSCode (M* Apple Silicon)
Chrome
CrossOver (for gaming / windows applications)
Docker Desktop
Onyx (edit hidden OSX settings)

Tweaks

Apple Mail

Smart inboxes => filter for over x years old to clean up old mails, or filter for "unsubscribe" to get rid of spam and unwanted mails.

More infos about tuning mail.app to fit your need in that apple knowledgebase article 

Finder

Open finder, press "Apple + ,", here are my tweaks:
=> General: Open folders in tabs .. [X]
=> Tags: Add new tags to find docs, like "work", "private" etc
=> Sidebar: Select what you want to see in the finders' sidebar
=> Advanced: See screenshot 


Thats all, leave a comment when you have more tweaks everyone should know about ;)

Why Is Customer Obsession Disappearing?

Many companies trade real customer-obsession for automated, low-empathy support. Through examples from Coinbase, PayPal, GO Telecommunications and AT&T, this article shows how reliance on AI chatbots, outsourced call centers, and KPI-driven workflows erodes trust, NPS and customer retention. It argues that human-centric support—treating support as strategic investment instead of cost—is still a core growth engine in competitive markets. It's wild that even with all the cool tech we've got these days, like AI solving complex equations and doing business across time zones in a flash, so many companies are still struggling with the basics: taking care of their customers. The drama around Coinbase's customer support is a prime example of even tech giants messing up. And it's not just Coinbase — it's a big-picture issue for the whole industry. At some point, the idea of "customer obsession" got replaced with "customer automation," and no...

What are the performance implications of cross-platform execution within Wayang?

Apache Wayang ® enables cross-platform execution across multiple data processing platforms such as Spark, Flink, Java Streams, PostgreSQL or GraphChi. This capability fundamentally changes the performance behavior of distributed data pipelines. Wayang reduces manual data movement by selecting where each operator should run, but crossing platform boundaries still introduces serialization cost, shifts in locality, different memory strategies and new tuning constraints. Understanding these dynamics is essential before adopting Wayang for multi-platform pipelines at scale. Apache Wayang is a cross-platform data processing framework that lets developers run a single logical pipeline across engines such as Apache Spark, Apache Flink or a native Java backend. It provides an abstraction layer and a cost-based optimizer that selects the execution platform for each operator. This flexibility introduces new performance variables that do not exist in single-engine systems. Engine boundaries ...

Building a Model-Agnostic Multi-Agent System with OpenClaw

Over one week we rebuilt our AI stack around OpenClaw’s multi-agent architecture to avoid provider lock-in and stop wasting premium tokens. By aligning models to tasks, diversifying fallbacks across providers, enforcing minimal tool access, and switching to memory-first workflows with ephemeral sessions, we reduced token usage per task by about 70% and cut our monthly bill by 77% while improving operational resilience. How We Achieved 77% Cost Reduction and Provider Independence Over the past week, we rebuilt our AI infrastructure around OpenClaw’s multi-agent architecture. The result was a 77% cost reduction , provider independence , and a delegation system that routes work to the most cost-effective model for each job. Below is the technical journey of optimizing a 7-agent squad with OpenClaw. The Challenge: Model Provider Lock-In We started with a simple problem: our entire squad defaulted to a single model provider. This created three issues: Cost inefficiency beca...
