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"

Install git and wget:
 brew install git
 brew install wget

Install oh-my-zsh:
 wget --no-check-certificate -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:

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

Solarized and Pathogen

mkdir -p ~/.vim/autoload ~/.vim/bundle; \  
curl -so ~/.vim/autoload/pathogen.vim \

cd ~/.vim/bundle
 git clone

Extended .vimrc:
cd ~/ && git clone && 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 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

curl –proto ‘=https’ –tlsv1.2 -sSf | sh

Download the binaries from
Sometimes I got into some trouble installing / updating Go, here's snippets to do so:

Additional tools I recommend

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


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 to fit your need in that apple knowledgebase article 


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 ;)

Deal with corrupted messages in Apache Kafka

Under some strange circumstances it can happen that a message in a Kafka topic is corrupted. This happens often by using 3rd party frameworks together with Kafka. Additionally, Kafka < 0.9 has no lock at at the consumer read level, but has a lock on Log.write(). This can cause a rare race condition, as described in KAKFA-2477 [1]. Probably a log entry looks like: ERROR Error processing message, stopping consumer: ($) kafka.message.InvalidMessageException: Message is corrupt (stored crc = xxxxxxxxxx, computed crc = yyyyyyyyyy Kafka-Tools Kafka stores the offset of every consumer in Zookeeper. To read out the offsets, Kafka provides handy tools [2]. But also can be used, at least to display the consumer and the stored offsets. First we need to find the consumer for a topic (> Kafka 0.9): bin/ --zookeeper management01:2181 --describe --group test Prior to Kafka 0.9 the only possibility to get this inform

Hive query shows ERROR "too many counters"

A hive job face the odd " Too many counters:"  like Ended Job = job_xxxxxx with exception 'org.apache.hadoop.mapreduce.counters.LimitExceededException(Too many counters: 201 max=200)' FAILED: Execution Error, return code 1 from org.apache.hadoop.hive.ql.exec.MapRedTask Intercepting System.exit(1) These happens when operators are used in queries ( Hive Operators ). Hive creates 4 counters per operator, max upto 1000, plus a few additional counters like file read/write, partitions and tables. Hence the number of counter required is going to be dependent upon the query.  To avoid such exception, configure " mapreduce.job.counters.max " in mapreduce-site.xml to a value above 1000. Hive will fail when he is hitting the 1k counts, but other MR jobs not. A number around 1120 should be a good choice. Using " EXPLAIN EXTENDED " and " grep -ri operators | wc -l " print out the used numbers of operators. Use this value to tweak the MR s
