Notes
This is a place for some personal notes. I try to use the zettelkasten method. Thats should help me to summarize all the input that I’m reading day by day. My workflow is dead simple with obsidian (nvim) and a synchronised folder to my private nextcloud and a github repository for converting all the notes to a mdBook. On my mobile (iPhone) actually I prefer to use obsidian (mobile) for editing my markdown files and sync these via WebDAV on my Nextcloud.

More natural splits opening
Open new split panes to right and bottom, which feels more natural than Vim’s default:
set splitbelow
set splitright
Resizing splits
Vim’s defaults are useful for changing split shapes:
"Max out the height of the current split
ctrl + w _
"Max out the width of the current split
ctrl + w |
"Normalize all split sizes, which is very handy when resizing terminal
ctrl + w =
More split manipulation
"Swap top/bottom or left/right split
Ctrl+W R
"Break out current window into a new tabview
Ctrl+W T
"Close every window in the current tabview but the current one

Coding style
At the linux kernel guideline are some good advices: The linux kernel - coding style Google have some guidelines for some languages as well. Use positive booleans for better readability, like described here | Google Code health
Principles
- YAGNI
- stop thinking about future possible mutation of your actual requirements, just let it simple
Code review
-
Be kind! People are more receptive to feedback if you assume competence and treat them with respect.
-
Focus your comments on the code, not the author. Avoid statements with the word ‘you’ which can give the impression that you are judging the person and not the artifact.
-
Explain why you are making the comment. You may be aware of alternatives that are not obvious to the author, or they may be aware of additional constraints.
-
Express the tradeoffs your suggestion entails and take a pragmatic approach to working with the author to achieve the right balance.
-
Approach your role as a guide, not a test grader. Balance giving direct guidance with leaving some degrees of freedom for the author.
-
Consider marking low priority comments with severity like Nit, Optional, or FYI to help the author prioritize the important ones.

Reducing size of git repository with git-replace
For reporitories with a huge history it takes a long time to clone this whole git overhead.
It relativy easy to spilit your history from one commit to a completly other repository.
- Create new repository (destination for your old history)
- Add this repository url to your huge repo:
git remote add project-history C:\repos\git-replace\history - Create a history branch from your latest commit (first commit of history repo)
git branch history 590f4d3 - Push this branch to history-repo
git push project-history history:main - Reduce size of main repo
git commit-tree -m "For historic commits, run 'git replace <child-ID> 590f4d3'" "590f4d3~^{tree}" d3bee05dac84c66b7d13f99a5edf790688f51494git rebase 590f4d3~ --onto d3bee05 --rebase-merges - Push small size to origin
git push origin main --force-with-lease - Clone fresh repo and add history repo to main as a branch
git remote add project-history C:\repos\git-replace\historygit fetch project-historygit branch history project-history/main - Replace a commit from main to history for connection
git replace 92305a9 590f4d3 - Delete replacement
git replace -d 92305a9

Git bisect
Find a bad commit with git bisect just run this command on a commit and mark them as git bisect good/bad checkout another and run again git bisect good/bad.
git bisect is able to find your first bad commit with i.e. git bisect run bin/rails rspec <FILE> and mark commit good/bad with the exitcode of your command.
Commit to an older hash
Run: git-amend.sh <older-hash>
hash=$1
git add .
git commit --fixup $hash
# 'GIT_EDITOR=true' makes the rebase non-interactive
GIT_EDITOR=true git rebase -i --autosquash $hash^

The usage of aliases from git plugin/oh-my-zsh: git-plugin zsh-load: zinit
Here are some git commands, that I NOT used daily. Mainly i use the zsh git plugin with all the useful short commands
(alias) like gs # git status and gcd # git checkout develop. It is really handy and i love it.
Checkout a subdir of a git repository
$ mkdir pcl-examples
$ cd pcl-examples #make a directory we want to copy folders to
$ git init #initialize the empty local repo
$ git remote add origin -f https://github.com/PointCloudLibrary/pcl.git #add the remote origin
$ git config core.sparsecheckout true #very crucial. this is where we tell git we are checking out specifics
$ echo "examples/*" >> .git/info/sparse-checkout #recursively checkout examples folder
$ git pull --depth=2 origin master #go only 2 depths down the examples directory
Switch to previous branch
git checkout -
- is an alias for the previous branch
Open all files with conflicts at once
git diff --name-only --diff-filter=U | uniq | xargs $EDITOR
What changed?
git whatchanged —-since=‘2 weeks ago’
Open a branch as new directory
git worktree add ../worktree2 master
git worktree remove ../f_branch_worktree

- Always, always try to get an Index Cond (called Index range scan in MySQL) instead of a Filter.
- Always, always, always assume PostgreSQL and MySQL will behave differently. Because they do.

Coding projects
In general there are some basic topics, you have to check before start a bigger project/application. These decisions are fundamental for the smooth development of a application.
Timestamp/Date persistance
How to deal with timestamps i.e. getting from user inputs? Do we wanna be timezone compatible with clients/users in different timezones? How to get timezone from user in my backend requests?
- persist timestamp and dates always in UTC in your database
- use of ISO8601 date/timestamp formats, but have to keep in mind on calculations
- most important; keep it consistant in your database
Logging/logfile analytics
What and when you should log something to your logfiles. Make a strategy about logging in general, to get information if you need some in your debugging session for a complex problem. Another great idea is, to have an external service to aggregate your logs for each project ie. rollbar. I would prefer to have for each project a aggregation of project wide logs of your application, hosts and client errors.
Internalisation i18n
Its always a good idea to start with an international translation files on your project. Its easy to looking for a phrase in your application and on the other hand its easy to add another language to your application, in case someone join your project with a different language. A great feature I saw on an project, to have a backend portal you get a possibility to edit you translations life for your keys.
Licenses
If you are planning to create a business, you must verify your licenses and dependencies to ensure they comply.
Wording
Create a list of terms that defines a particular aspect of a use-case to ensure all participants are referring to it in the same manner during conversations.

Step 3: Generate Solid Queue installation files
# $ rails generate solid_queue:install
Step 4: Run migrations
# $ rails db:migrate
Step 5: Update config/application.rb
# Rails.application.configure do
# config.active_job.queue_adapter = :solid_queue
# end
Step 6: Remove Sidekiq initializer
# Delete or comment out config/initializers/sidekiq.rb
Step 7: Update worker process command in Profile or deployment scripts
# Old: worker: bundle exec sidekiq
# New: worker: bundle exec rails solid_queue: start
Step 8: Remove Redis configuration related to Sidekiq
# Check config/redis.yml or any Redis initializers
Step 9: Update any Sidekiq-specific code in your jobs
Before:
# class MyJob
# include Sidekiq: :Worker
# def perform(args)
# job logic
# end
# end
After:
# class MyJob < ApplicationJob
# queue_as: default def perform(args)
# job logic
# end
Step 10: Update any Sidekiq-specific API calls
# Before: Sidekiq:: Client.push( 'class' => MyJob,
# After: MyJob. perform_later (1, 2, 3)
Step 11: Set up Mission Control (optional)
# In Gemfile:
gem 'mission_control-jobs'
# In config/routes.rb:
Rails.application.routes.draw do
mount MissionControl::Jobs::Engine, at: "/jobs"
end
Step 12: Remove any Sidekiq web UI routes
# Delete or comment out in config/routes.rb:
# require 'sidekiq/web'
# mount Sidekiq:: Web => '/sidekiq'
Responsible monkeypatch
Here’s the list of rules I try to follow:
- Wrap the patch in a module with an obvious name and use
Module#prependto apply it - Make sure you’re patching the right thing
- Limit the patch’s surface area
- Give yourself escape hatches
- Over-communicate
# ActionView's date_select helper provides the option to "discard" certain
# fields. Discarded fields are (confusingly) still rendered to the page
# using hidden inputs, i.e. <input type="hidden" />. This patch adds an
# additional option to the date_select helper that allows the caller to
# skip rendering the chosen fields altogether. For example, to render all
# but the year field, you might have this in one of your views:
#
# date_select(:date_of_birth, order: [:month, :day])
#
# or, equivalently:
#
# date_select(:date_of_birth, discard_year: true)
#
# To avoid rendering the year field altogether, set :render_discarded to
# false:
#
# date_select(:date_of_birth, discard_year: true, render_discarded: false)
#
# This patch assumes the #build_hidden method exists on
# ActionView::Helpers::DateTimeSelector and accepts two arguments.

Some notes while doing the udamy course and some ruby notes:
Basics
Render plain text:
def hello
render plain: "hello world!"
end
Create a controller with a method and use a object in view:
# controller
class TodosController < ApplicationController
def new
@todo = Todo.new
end
end
# view
<%= form_for @todo do |f| %>
<% end %>
Use flash for notifications:
#controller
@todo.save
flash[:notice] = "Todo was created successfully"
# view
<% flash.each do |name, msg| %>
<ul>
<li><%= msg %></li>
</ul>
<% end %>
A bootstrap styled flash messages:
<div class="row">
<div class="col-md-10 col-md-offset-1">
<% flash.each do |name, msg| %>
<div class="alert alert-<%= name %>">
<a href="#" class="close" data-dismiss="alert">×</a>
<%= msg %>
</div>
<% end %>
</div>
</div>
Render partials in view ie a file views/layouts/_messages.html.erb:
<%= render 'layouts/messages' %>
Before run a method do action:
# controller
before_action :set_todo, only: [:edit, :update, :show, :destroy]
private
def set_todo
@todo = Todo.find(params[:id])
end
def todo_params
params.require(:todo).permit(:name, :description)
end
# permit has_many list
def recipe_params
params.require(:recipe).permit(:name, :description, ingredient_ids: [])
end
end
Add pg to production for ie. heroku deployment:
group :production do
gem 'pg'
end
bundle install --without production
Some simple validations:
validates :name, presence: true
validates :description, presence: true, length: { minimum: 5, maximum: 500 }
Application helpers:
helper_method :current_chef, :logged_in?
def current_chef
@current_chef ||= Chef.find(session[:chef_id]) if session[:chef_id]
end
def logged_in?
!!current_chef
end
def require_user
if !logged_in?
flash[:danger] = "You must be logged in to perform that action"
redirect_to root_path
# also possible
redirect_to :back
end
end
Render partial for model:
# View
<% if recipe.ingredients.any? %>
<p>Ingredients: <%= render recipe.ingredients %></p>
<% end %>
# Now create a new partial _ingredient.html.erb under the app/views/ingredients folder for this to work
<span class="badge"><%= link_to ingredient.name,
ingredient_path(ingredient) %> </span>
Model
Order models by column:
# order by updated_at -> top of model
default_scope -> { order(updated_at: :desc) }
Get just the last 20 entries of a model
def self.most_recent
order(:created_at).last(20)
end
Routes
Set root route:
# router.rb
root "pages#home"
Specific route to controller#method:
get '/about', to: 'pages#about'
Nested routes:
resources :recipes do
resources :comments, only: [:create]
end
# Form in view
<%= form\_for(\[@recipe, @comment\], :html => {class: "form-horizontal",
role: "form"}) do |f| %>
Links
Create links in views:
<%= link_to "Edit this todo", edit_todo_path(@todo) %>
<%= link_to "Back to todos listing", todos_path %>
<td><%= link_to 'delete', todo_path(todo), method: :delete, data: { confirm: "Are you sure?"} %></td>
<%= link_to "MyRecipes", root_path, class: "navbar-brand", id: "logo" %>
<%= link_to "Sign up or log in", "#" class: "btn btn-danger btn-lg" %>
Tests
Create integration test for model:
rails generate integration_test recipes
Simple test root path:
test "should get home" do
get pages_home_url
assert_response :success
end
test "should get root" do
get root_url
assert_response :success
end
to fix this tests, do:
root "pages#home"
get 'pages/home', to: 'pages#home'
# controller
class PagesController < ApplicationController
def home
end
end
Test a simple validation:
require 'test_helper'
class RecipeTest < ActiveSupport::TestCase
def setup
@recipe = Recipe.new(name: "vegetable", description: "great vegetable recipe")
end
test "recipe should be valid" do
assert @recipe.valid?

assert_not @recipe.valid?
end
test "description shouldn't be more than 500 characters" do
@recipe.description = "a" * 501
assert_not @recipe.valid?
end
test "should get recipes show" do
get recipe_path(@recipe)
assert_template 'recipes/show'
assert_match @recipe.name, response.body
assert_match @recipe.description, response.body
assert_match @chef.chefname, response.body
end
test "should get recipes listing" do

assert_template 'recipes/index'
assert_select "a[href=?]", recipe_path(@recipe), text: @recipe.name
assert_select "a[href=?]", recipe_path(@recipe2), text: @recipe2.name
end
end
Test a email validation:
require 'test_helper'
class ChefTest < ActiveSupport::TestCase
def setup
@chef = Chef.new(chefname: "mashrur", email: "mashrur@example.com")
end
test "should be valid" do

test "email should be unique and case insensitive" do
duplicate_chef = @chef.dup
duplicate_chef.email = @chef.email.upcase
@chef.save
assert_not duplicate_chef.valid?

# chef model
validates :chef_id, presence: true
has_many :recipes
# recipe model
belongs_to :chef
# destroy with dependent
has_many :recipes, dependent: :destroy
Test
def setup

@recipe = @chef.recipes.build(name: "vegetable", description: "great vegetable recipe")
end
test "recipe without chef should be invalid" do
@recipe.chef_id = nil
assert_not @recipe.valid?
end
Styling
Add bootstrap to project (good html/css tutorial link):
gem 'bootstrap-sass', '~> 3.3.7'
gem 'jquery-rails'
# app/assets/javascripts/application.js
//= require bootstrap-sprockets
# app/assets/stylesheets/custom.css.scss
@import "bootstrap-sprockets";
@import "bootstrap";
Views
Render html for each data:
<%= f.collection_check_boxes :ingredient_ids,
Ingredient.all, :id, :name do |cb| %>
<% cb.label(class: "checkbox-inline input_checkbox") {cb.check_box(class: "checkbox") + cb.text} %>
<% end %>
Database
Create migration:
rails generate migration create_recipes
# modify the migration file
rails db:migrate
Rename column:
rename_column :recipes, :email, :description
rails db:migrate
Many to many association:
# Model
has_many :recipe_ingredients
has_many :recipes, through: :recipe_ingredients

Prevent useEffect render on mount

export function useDidUpdateEffect(
effect: EffectCallback,
deps?: DependencyList
) {
// a flag to check if the component did mount (first render's passed)
// it's unrelated to the rendering process so we don't useState here
const didMountRef = useRef(false);
// effect callback runs when the dependency array changes, it also runs
// after the component mounted for the first time.
useEffect(() => {
// if so, mark the component as mounted and skip the first effect call
if (!didMountRef.current) {
didMountRef.current = true;
} else {
// subsequent useEffect callback invocations will execute the effect as normal
return effect();
}

PREMIUM = ->(val) { val + 10 }
DISCOUNT = ->(val) { val * 0.90 }
ROUND_TO_CENT = ->(val) { val.round(2) }
# One presenter
PRESENT = ->(val) { val.to_f }
# Pre-define some rule sets for some pricing scenarios
REGULAR_SET = [FEE, TAX, ROUND_TO_CENT, PRESENT]
PREMIUM_SET = [FEE, PREMIUM, TAX, ROUND_TO_CENT, PRESENT]

Do you want to avoid mucking about with kernel modules?
XFS on LVM
Use btrfs on your root (/) volume. But at least make /home xfs.
And have backups. borg backup is good.

10 Things after installation
Source: Average Linux User
Check your current kernel: uname -r
1. Install an LTS kernel and reconfigure grub:
sudo pacman -S linux-lts
sudo grub-mkconfig -o /boot/grub/grub.cfg
You may also install linux-lts-headers. Reboot and check which kernel is in use with uname -r.
Remove non-lts kernel sudo pacman -Rs linux
2. Install Microcode
For intel processors with grub boot loader:
sudo pacman -S intel-ucode
sudo grub-mkconfig -o /boot/grub/grub.cfg
For AMD processors install linux-firmware package.
3. Disable GRUB delay
Add the following to /etc/default/grub: achieve the fastest possible boot:
GRUB_FORCE_HIDDEN_MENU="true"
Then put file 31_hold_shift to /etc/grub.d/. Download 31_hold_shift https://goo.gl/nac6Kp
Make it executable, and regenerate the grub configuration:
sudo chmod a+x /etc/grub.d/31_hold_shift
sudo grub-mkconfig -o /boot/grub/grub.cfg
4. Install some key packages
sudo pacman -S adobe-source-sans-pro-fonts aspell-en enchant gst-libav gst-plugins-good hunspell-en icedtea-web jre8-openjdk languagetool libmythes mythes-en pkgstats ttf-anonymous-pro ttf-bitstream-vera ttf-dejavu ttf-droid ttf-gentium ttf-liberation ttf-ubuntu-font-family
5. Set up firewall
Install ufw:
sudo pacman -S ufw
Enable it.
sudo ufw enable
Check its status:
sudo ufw status verbose
Enable the start-up with the system:
sudo systemctl enable ufw.service
Reboot and check the status again. It should be active.
6. Encrypt your home directory
Logged out. Switch to a console with Ctrl+Alt+F2. Login as a root and check that your user own no processes:
ps -U username
Install the necessary applications:
sudo pacman -S rsync lsof ecryptfs-utils
Then encrypt your home directory:
modprobe ecryptfs
ecryptfs-migrate-home -u username
Mount your encrypted home.
ecryptfs-mount-private
Unwrap the passphrase and save it somewhere where only you can access it.
ecryptfs-unwrap-passphrase
Run
ls .ecryptfs
Edit /etc/pam.d/system-auth:
After the line “auth required pam_unix.so” add:
auth required pam_ecryptfs.so unwrap
Above the line “password required pam_unix.so” insert:
password optional pam_ecryptfs.so
After the line “session required pam_unix.so” add:
session optional pam_ecryptfs.so unwrap
Reboot and make sure that you can login to your desktop
7. Remove orphans
sudo pacman -Rns $(pacman -Qtdq)
8. Optimize pacman’s database access speeds
sudo pacman-optimize
9. Check for errors
sudo systemctl --failed
sudo journalctl -p 3 -xb
10. Backup the system
sudo rsync -aAXvP --delete --exclude=/dev/* --exclude=/proc/* --exclude=/sys/* --exclude=/tmp/* --exclude=/run/* --exclude=/mnt/* --exclude=/media/* --exclude=/lost+found --exclude=/home/.ecryptfs / /mnt/backupDestination/

You can also manipulate the content with cpdf
cpdf -draft in.pdf -o out.pdf # Remove images
cpdf -blacktext in.pdf -o out.pdf # Convert all text to black color
Monitor the progress in terms of generated output
Write random data, encode it in base64 and monitor how fast it is being sent to /dev/null
cat /dev/urandom | base64 | pv -lbri2 > /dev/null
Scrum
Thats the most prefered agile software development method that I mostly worked with in DIFFERENT ways and most of the time, in a bad way (non-productive).
Daily
-
good way:
Everbody talk about their blockers or challenges for the task of that day. Pushes some urgent pull-requests for code-review or ask for clearafications from front-/back-end. Talk about upcoming releases and their open todos.
-
bad way:
Everyone just saying what they did yesterday and whats the plan for that day.
Review
-
good way:
Present something important things or howto for usage of a finished feature to the product owner.
-
bad way:
Everyone summarize the tasks of the finished sprint from own perspective.
Retrospective
-
good way:
Great tool for retrospectives is team-o-clock goretro
-
Step 1 (retro):
Everyone inputs some points into the i.e. following columns.
-
| House of straw | House of sticks | House of bricks |
|---|---|---|
| … | … | … |
| Start | Stop | Continue |
|---|---|---|
| … | … | … |
| Liked | Learned | Lacked | Longed for |
|---|---|---|---|
| … | … | … | … |
-
-
Step 2 (grooming):
Everyone groom this points together (group them if same topic)
-
Step 3 (voting):
Everyone awards 3-5 points in total to their most important topics (points)
-
Step 4 (discussion):
In order to the most important points, everyone explain their point in more detail and discuss together what needs todo.
-
Step 5 (actions):
Collect some actions (todos) and plan them into the next sprint.
-
-
bad way:
Just ask for some complications, mostly without some feedback.
Planning
-
good way:
Create a good plan about the process of the next sprint with related tasks from frontend & backend.
-
bad way:
Just put some tasks into the next sprint and probably assign these to someone.
Refinement
-
good way:
Talk about tasks and pick someone from backend/frontend to make some technical assumptions about a possible approach.
-
bad way:
Just ask about question to some tasks and clearify these in a discussion.

Database correction
Sometimes getting wrong data from my smart meter, that one have to fix in database with the SQlite Web add-on on my home-assistant instance, with following commands:
SELECT *
FROM "statistics" WHERE CAST(mean AS DECIMAL(12,6)) LIKE '3976%'
UPDATE "statistics"
SET mean = OtherTable.Col1,
Col2 = OtherTable.Col2
FROM (
SELECT *
FROM "statistics" WHERE CAST(mean AS DECIMAL(12,6))
LIKE '3976%')

Security quote
Security is a team sport, and accelerating SFI isn’t just job number one for our security teams – it’s everyone’s top priority and our customers’ greatest need. If you’re faced with the tradeoff between security and another priority, your answer is clear: Do security. In some cases, this will mean prioritizing security above other things we do, such as releasing new features or providing ongoing support for legacy systems. This is key to advancing both our platform quality and capability such that we can protect the digital estates of our customers and build a safer world for all. - Satya

Polyglot files
With a polyglot file, you re able to compromise a file upload with restricted file-types.
cat beispiel.pdf beispiel.zip > polyglot-pdf.zip
This zip file, will be recognized as a pdf file:
$ file polyglot-pdf.zip
polyglot-pdf.zip: PDF document, [...]
If a backend just checks the content-type its still PDF. So if you download this file and get original file as .zip file and extract it, you will get the pdf & zip file included there.

For my first try, I build a ferris sweep with Kailh Low Profile Choc Switches, Blank MBK Choc Low Profile Keycaps and two Elite-Pi controllers from splitkb.com.
Some more details about my walkthrough this journey and its actual state:
- Get your ferris sweep pcb, got my from a friend @mberrio
- buy all the components, i.e. here splitkb.com
- solder this on your pcb, howto
After finish the hardware, you have to flash your controllers. For me its two Elite-Pi controllers on my sweep (left & right).
- install qmk and test the first compile
- create a keymap with configurator
- set handedness to elite-pi with
make CONVERT_TO=kb2040 ferris/sweep:default:uf2-split-left
make CONVERT_TO=kb2040 ferris/sweep:default:uf2-split-right
- each command creates a
.uf2file, that the firmware file for each side to be configured once on each side - plug-in each controller (first time starts in boot mode) and copy
.uf2to DF2 usb storage (it restarts & flash automatically) - create firmware, i.e. like this
qmk compile -kb ferris/sweep -km default -e CONVERT_TO=elite_pi - copy created
.uf2file to each controller
After flashing your have a running ferris sweep split keyboard, which you must now learn to love. Take a lot of time to get to know each other …
Play around with the configurator and create your own keymap.json file. If you ready to learn, print your keymap here and start typing.

MacOS Brew install older version
- You create a local “tap” - which I assume is something like a local brew repository
- You extract the desired version of the package into this local tap
- You install your local tap
# use $USER variable to mimick userName/repoName structure
# this does not actually create any git repositories
# 1. create a new tap
brew tap-new $USER/local-<packageName>
# 2. extract into local tap
brew extract --version=1.2.3 <packageName> $USER/local-<packageName>
# 3. run brew install@version as usual
brew install <packageName>@1.2.3
If not found:
# list all local taps
brew tap
# go to tap and check out correct hash
cd /usr/local/Homebrew/Library/Taps/<packageName>
git checkout <hash>
# prevent brew from checking out different hash
HOMEBREW_NO_AUTO_UPDATE=1 brew install <packageName>
# can list and switch between all versions

Custom sortation of database entries
Found an good article about, how handle the custom sortation of entires in sql database. TL;DR just add an column pos to the table and auto-increment this value. If insert an entry between of some rows, just calculate the new position for this entry like: ((pos n-1 + pos n+1) / 2
i.e.:
| names | pos | | peter | 1 | | tom | 2 | | harry | 2.5 | | ben | 3 |

Imperium USA by Daniele Ganser ISBN: 978-3-946778-27-1 ⭐ ⭐ ⭐ ⭐
US-Offiziere wie General Butler wissen, dass der US-Imperialismus in Lateinamerika rücksichtslos wütete. »Von 1909 bis 1912 war ich an der Säuberung Nicaraguas für das internationale Bankhaus Brown Brothers beteiligt«, erinnert sich Butler. »1916 habe ich den amerikanischen Zucker-baronen die Dominikanische Republik serviert. In China half ich, dafür zu sorgen, dass Standard Oil ungestört seinen Geschäften nachgehen konnte. In diesen Jahren hatte ich, wie die Jungs in den Hinterzimmern sagen würden, eine prächtige Gangsterbande am Laufen. Wenn ich so zurückblicke, glaube ich, dass ich Al Capone ein paar Tipps hätte geben können. Er schaffte es gerade einmal, mit seiner Bande in drei Bezirken zu operieren. Ich operierte auf drei Kontinenten.«
Black Elk, der Medizinmann der Oglala Sioux, war ein Vertreter der Friedensbewegung und beschrieb diese Verbundenheit mit der Mensch-heitsfamilie so: »Der erste Friede - der wichtigste - ist der, welcher in die Seelen der Menschen einzieht, wenn sie ihre Verwandtschaft, ihre Harmonie mit dem Universum einsehen und wissen, dass im Mittelpunkt der Welt das große Geheimnis wohnt, und dass diese Mitte tatsächlich überall ist. Sie ist in jedem von uns - dies ist der wirkliche Friede, alle anderen sind lediglich Spiegelungen davon. Der zweite Friede ist der, welcher zwischen Einzelnen geschlossen wird, und der dritte ist der zwischen Völkern. Aber vor allem sollt ihr sehen, dass es nie Frieden zwischen Völkern geben kann, wenn nicht der erste Friede vorhanden ist, der, wie ich schon sagte, innerhalb der Menschenseele wohnt.«
Einzeln sein by Rüdiger Safranski ISBN: 978-3-446-25671-2 ⭐ ⭐ ⭐ ⭐
Das ist die Pointe des Ganzen: Der Sinn von Sein ist die Zeit. Es gibt nichts Beharrendes. Wenn der Sinn von Sein die Zeit ist, so heißt das: Keine übergreifende Idee, kein Gott, kein Ziel der Geschichte und so fort verbürgen diesen Sinn, wie das in der Tradition üblich ist. Es bleibt die Zeit, die zwar nicht aufhört, aber in der wir aufhören, weil wir befristet sind. Unsere Zeit ist die befristete, die tödliche Zeit.
Der Denkende ist zwar vereinzelt, aber nicht einsam, denn er bleibt in Gesellschaft - mit sich selbst. Denken, so Hannah Arendt, ist mit der Erfahrung des inneren Gesprächs mit sich selbst verbunden: Das Denken ist, existentiell gesehen, etwas, das man allein tut, aber nicht einsam: allein sein heißt mit sich selbst umgehen; einsam sein heißt alleine sein, ohne sich in das Zwei-in-einem aufspalten zu können, ohne sich selbst Gesellschaft leisten zu können.
Dieser Vergleichszwang begünstigt zwar Wettbewerb und Konkurrenz und damit das Streben nach überbietender Originalität, doch es entstehen eben auch neue Anpassungszwänge. Der Vergleichshorizont weitet sich, und es wird immer schwieriger, für sich selbst Maßstäbe und Orientierungen zu finden. In Anbetracht der vielen Möglichkeiten und Angebote ist das Eigene, was immer es bedeuten mag, in Ge-fahr, entwertet zu werden. Und so schließt man sich eben einer Kohorte an und übernimmt die dort maßgeblichen Standards beim Lebens-stil, bei Meinungen und Uberzeugungen.

21 Lektionen by Yuval Noah Harari ISBN: 978-3406739682 ⭐ ⭐ ⭐ ⭐
-
Ein gutes Buch über die aktuellen Gegebenheiten in der Welt. Und sehr viel pro westl. Politik ohne Reflektion.
Was also sollten wir unterrichten? Zahlreiche Fachpädagogen behaupten, Schulen sollten sich auf die Vermittlung der vier Ks verlegen kritisches Denken, Kommunikation, Kollaboration und Kreativität. Allgemeiner sollten Schulen weniger Wert auf technisches Können legen und stattdessen universell anwendbare Lebensfertigkeiten in den Mittelpunkt rücken. Am allerwichtigsten wird die Fähigkeit sein, mit Veränderung umzugehen, neue Dinge zu lernen und in unvertrauten Situationen das seelische Gleichgewicht zu wahren. Wollen wir mit der Welt des Jahres 2050 Schritt halten, müssen wir nicht nur neue Ideen und Produkte erfinden wir müssen vor allem uns selbst immer wieder neu erfinden.“
Den Menschen wurde von frühester Kindheit an beigebracht, an die Erzählung zu glauben. Sie hören sie von ihren Eltern, ihren Lehrern, ihren Nachbarn und der allgemeinen Kultur lange, bevor sie die geistige und emotionale Unabhängigkeit entwickeln, die notwendig ist, um solche Geschichten zu hinterfragen und auf ihren Wahrheitsgehalt zu überprüfen. Zu der Zeit, da ihr Intellekt heranreift, sind sie so sehr in diese Erzählung eingebunden, dass sie ihren Verstand eher dazu nutzen, sie rational zu begründen als sie anzuzweifeln. Die meisten Menschen, die auf ldentitätssuche gehen, sind wie Kinder, die sich auf Schatzsuche begeben. Sie finden nur, was ihre Eltern zuvor für sie versteckt haben.

Youtube Grenzgänger - Shayan Garcia trifft Aufspürerin Video
Die Vergnügungsmaschine der kapitalistischen Kultur versucht jedes Gefühl für unsere Geschichte zu eliminieren. Damit die Gegenwart zu einer dauerhaften Wiederholung des hedonistischen Moments verkommt (nur auf das eigene Glück aussein) Das Gefangensein im immer Gleichen fördert nicht nur die Geschichtsvergessenheit, sondern auch die Ablehnung einer alternativen Zukunftsvision. Besonders junge Menschen sind heute im Kreislauf einer sofortigen Triebbefriedigung gefangen. Sie leben in einem Dauerrausch, es ist nicht nur die Sucht nach Sex und Drogen verbreitetet, sondern auch die Sucht nach Status und Erfolg. Die Sucht nach einer hohen Sichtbarkeit und Resonanz. In den kapitalistischen Zivilisationen ist gegen die Seelen der Jugendlichen ein Kampf zugange. Sie werden so dermassen abgestumpft, damit aus ihnen keine Wahrheitssucher und Kämpfer für Gerechtigkeit werden - Prof. Cornel West

Marderhunden und Schleichkatzen wird lebendig das Fell über die Ohren gezogen. Die stossen Todesschreie aus und brüllen, und dabei kommen Aerosole zustande. Dabei kann sich dann der Mensch mit dem Virus anstecken. Diese Tiere waren bei Sars-1 eindeutig die Quelle. Das ist wissenschaftlich belegt.

Das Kamel als religiöses Opfertier hat eine lange Tradition, eine sehr hohe Wertigkeit. Aber es kostet auch sehr viel Geld. Arme religiöse Menschen nehmen stattdessen Schafe. Aber je mehr Leute in jener Region reich wurden, umso mehr Kamele wurden geopfert. So werden heute beispielsweise zur Hadsch-Saison auf der Arabischen Halbinsel allein als Opfertiere jedes Jahr 40’000 Kamele geschlachtet. Das hat es vor fünfzig Jahren noch nicht einmal in Ansätzen gegeben. Letztlich, wo auch immer auf der Welt, geht es um die Modifikation von natürlichen Systemen: Eine grosse Nutztierpopulation an irgendeinem Ort ist immer etwas Künstliches.

Alle, die sich nicht impfen lassen, werden sich mit Sars-2 infizieren. Der Begriff Herdenimmunität stammt aus der Veterinärmedizin, wo man sich in früheren Jahren tatsächlich solche Überlegungen gemacht hat, zum Beispiel beim Rinderpestvirus, dem Masernvirus der Rinder. Hochübertragbar, aber durch eine Impfung lebenslang abzuhalten. Da kann man eben dann wirklich solche Rechnungen anstellen: Wir haben einen Nutztierbestand, der ist in sich abgeschlossen – wie viele von den Tieren müssen wir jetzt impfen, damit das Virus nicht zirkulieren kann?

False balance? Dass man sagt: Okay, hier ist eine Mehrheitsmeinung, die wird von hundert Wissenschaftlern vertreten. Aber dann gibt es da noch diese zwei Wissenschaftler, die eine gegenteilige These vertreten. In der medialen Präsentation aber stellt man dann einen von diesen hundert gegen einen von diesen zweien. Und dann sieht das so aus, als wäre das 50:50, ein Meinungskonflikt. Und dann passiert das, was eigentlich das Problem daran ist, nämlich dass die Politik sagt: «Na ja, dann wird die Wahrheit in der Mitte liegen.» Das ist dieser falsche Kompromiss in der Mitte.

Brot backen
Sauerteig:
-
75 g Mehl (zum Beispiel Dinkel- oder Roggenmehl)
-
75 ml lauwarmes Wasser
-
2 große Einmachgläser mit je mindestens 1,5 Liter (gibt es z.B. bei ** oder **Amazon), auf dem der Deckel locker aufsitzt und noch Luft durchlässt
-
einen Holzlöffel
-
Am ersten Tag gibst du 75 Gramm Mehl und 75 Milliliter lauwarmes Wasser in das Einmachglas und rührst mit dem Holzlöffel gut um. Der Teig sollte, wie ein Waffelteig, leicht flüssig sein.
-
Setze den Deckel (ohne Gummiring und ohne Klammern – der Sauerteig benötigt Luft) auf das Glas und stelle es an einen warmen Ort. Die optimale Temperatur für die Gärung beträgt zwischen 25 und 35 Grad Celsius.
-
Lasse den Teig für zwölf Stunden ruhen und rühre ihn dann mit dem Holzlöffel erneut gründlich um. Lasse ihn danach wieder für zwölf Stunden ruhen.
-
Gib vom zweiten bis zum vierten Tag täglich 75 Gramm Mehl und 75 Milliliter lauwarmes Wasser hinzu, rühre den Teig gut um und lasse ihn wieder 24 Stunden ruhen.
-
Am fünften Tag ist der Sauerteig fertig zum Weiterverarbeiten und du kannst nach dem folgenden Rezept Brot backen.
Brot:
-
400g Sauerteig
-
600g Mehl
-
250 bis 450ml lauwarmes Wasser (je nach Mehltyp, Vollkornmehl benötigt mehr Wasser als Auszugsmehl)
-
1 EL Salz
-
Rührschüssel
-
Holzlöffel
-
deine Hände oder eine Küchenmaschine
-
große Backform (zum Beispiel bei **Memolife) oder Backblech für den Laib
-
Butter oder Pflanzenöl zum Einfetten von Form/Blech
-
hitzebeständiges Gefäß mit Wasser (zum Beispiel eine Auflaufform)
-
Messer
-
Gib alle Zutaten in die Schüssel und rühre kräftig um.
-
Wenn der Teig eine schön feste Konsistenz hat und nicht an deinen Fingern kleben bleibt, fange an, den Teig für einige Minuten gründlich zu kneten. Mache dies entweder per Hand oder lasse deine Küchenmaschine für dich arbeiten.
-
Forme nach dem Kneten einen Laib aus dem Teig. Du kannst einen runden/ovalen Laib formen und auf das Backblech geben oder eine gefettete Backform nutzen.
-
Lasse den Brotrohling nun knapp eine Stunde im warmen Backofen bei 35 Grad Celsius gehen. Heize dafür den Backofen auf 50 Grad vor, stelle ihn wieder aus und gib den Rohling hinein. So geht der Sauerteig in der Restwärme ohne zu viel Energieaufwand.
-
Nimm nach einer Stunde den Rohling heraus, stelle den Ofen auf 175 Grad Umluft und gib die Auflaufform mit dem Wasser unten in den Backofen. Durch die Zugabe des Wassers wird das Brot nicht zu trocken und es bildet sich beim Backen eine schöne Kruste auf deinem Brot.
-
Schneide deinen Brotrohling nun an mehreren Stellen quer über der Oberfläche ein.
-
Gib den Rohling in den heißen Backofen und backe ihn für circa 45 Minuten.

Pizza recipe
Basically you could use each pizza dough calculator on the internet. I actually prefer the oni app with 63% hydration for an home oven.
Neapolitan 6pcs:
24h:
- 1000g flour (caputo)
- 620ml water
- 3g dry east
- 30g salt
Neapolitan 10pcs:
Poolish (16-24h):
- 300ml water
- 5g dry yeast (fresh 10g)
- 5g honey
- 300g flour 00
Dough:
- 700ml water
- poolish (all)
- 40g sea salt
- 1250g flour
Neapolitan:
- 500g Mehl
- 350g Wasser (kalt)
- 15g Salz
- 0.5g Hefe
16h bei Zimmertemperatur, 270g große Teiglinge, dann 6h Zimmertemperatur
Mehl und Wasser kurz verrühren und 20-30 Minuten abgedeckt stehen lassen. Anschließend Hefe und Salz zugeben und mit dem Knethaken der Küchenmaschine 5-8 Minuten auf langsamer Stufe, dann 8-10 Minuten auf zweiter Stufe zu einem elastischen Teig auskneten. Der Teig ist ausgeknetet, wenn er sich ohne zu reißen in die Länge ziehen lässt (Fenstertest). Den Teig für 18-48 Stunden luftdicht verschlossen im Kühlschrank reifen lassen. Je länger er reift, desto aromatischer und großpori- ger wird am Ende die Pizza. Den Teig aus dem Kühlschrank neh- men, in vier gleich schwere Stücke teilen. Zu Kugeln formen, gut abdecken oder verschließen und etwa 4 Stunden bei Raumtempe- ratur gehen lassen, bis sich das Volumen deutlich vergrößert hat. Mindestens 30 Minuten vor dem Backen: Den Backofen mit Kera- mikbackstein auf 275 °C Ober-/Unterhitze vorheizen. Tomaten, Salz und Olivenöl mit den Händen zu einer stückigen Soße zerdrü- cken. Basilikum waschen, trockenschütteln, etwa 2/3 der Blätt- chen grob zerrupfen und untermengen.

Lifehacks
Elternschaft ist schon eine lustige Sache. Du versuchst etwas zu tun, von dem niemand jemals wusste, wie man es richtig macht. Aber du willst dein Bestes geben! Also was kannst du am besten tun? Das Erste ist, ein wenig an sich selbst zu arbeiten. Verbringe genügend Zeit mit dir selbst. Schau dich genau an: Wie du bist, wie du sitzt, wie du stehst, wie du sprichst, was du machst, was du nicht machst. Ich denke, man muss sich selbst sehr genau betrachten. Denn die Kinder erfassen alles schnell und sie werden das, was du tust, verstärken. Eines der wichtigsten Dinge ist, sich zumindest so zu gestalten, wie man sein möchte. Jemand ist damit vielleicht nicht einverstanden. Das ist egal! Zumindest hast du versucht so zu sein, wie du dich magst. Das ist das Mindeste, was du tun kannst. Vielleicht erfüllst du die Erwartungen anderer nicht. Wir wissen nicht, was andere für Wertvorstellungen haben. Aber wenigstens musst du so werden, wie du dich magst. - Sadhguru

Spaced repetition
Writing good prompts forces one to circle around a concept, look at it from multiple angles, probe its properties, link it to other concepts through similarities and differences, reason about consequences and significance, derive parts of it from more fundamental pieces, and come up with a few concrete examples of it. These are the things that really build understanding.

Drug dealer vs. doctor
If your doctor prescribes you medication without first asking about …
- your diet
- your sleep
- your exercise routine
- your water consumption
- whether you have any structural issues
- the stress in your life Then you don’t have a doctor, you have a drug dealer.
Best summary of good food practice
-
Die ganze Farbpalette Gemüse, Salate, Kräuter und Früchte sind wertvolle Lieferanten für Mikronährstoffe und sekundäre Pflanzenstoffe, wovon Ihr Stoffwechsel, Immunsystem und Energielevel profitieren. Essen Sie so bunt wie möglich: Die Farben von Gemüse und Obst stehen für verschiedene Nährstoffe und wertvolle sekundäre Pflanzenstoffe. Stellen Sie sich einen bunten Mix zusammen, um von deren Gesundheitsvorteilen zu profitieren. Wenn Sie zu saisonalen Sorten greifen, essen Sie automatisch abwechslungsreich.
-
Kurze Wege Lebensmittel aus der Region liefern Ihnen mehr Vitamine und sekundäre Pflanzenstoffe als gespritzte Gewächshausware aus dem Süden – und sie sind besser für die Umwelt. Es gibt viele Arten, sich gesund zu ernähren. Dass es dabei vorrangig auf die Qualität der Lebensmittel ankommt, beweisen die ältesten Menschen der Welt, die sich hauptsächlich von unverarbeiteten Lebensmitteln ernähren, die in ihrer Region wachsen und gedeihen. Der Weg zum Bauern in der Nähe lohnt sich: Alte Obstsorten aus der Region sind oft verträglicher für Allergiker. Gerade bei tierischen Produkten kommt es auf Qualität und Herkunft an. Je besser die Tiere ernährt und gehalten werden, desto mehr gesunde Nährstoffe stecken in Fleisch, Eiern und Milchprodukten.
-
Überwiegend pflanzlich Hochwertige, pflanzliche Lebensmittel wie Gemüse, Obst, Kräuter, Nüsse und heimische Vollkorngetreide liefern uns viele Nährstoffe pro Kalorie. Forschungsergebnisse zeigen, dass eine gute Versorgung mit Mikronährstoffen ein entscheidender Faktor bei der Prävention ist.1,2 Pflanzliche Lebensmittel sind zudem unsere einzige Quelle für darmgesunde Ballaststoffe. Es reicht, wenn Sie den Fokus Ihrer Ernährung auf pflanzliche Lebensmittel legen. Sie müssen sich nicht ausschließlich pflanzlich ernähren, um gesund zu essen.
-
Dem Darm eine Pause gönnen Unser Darm beeinflusst unsere Gesundheit in vielen Bereichen. Er beeinflusst, wie gut wir Nährstoffe aufnehmen, er ist Teil unseres Immunsystems und er ist auch ein wichtiger Hormonproduzent. Mit einer vorwiegend pflanzlichen, ballaststoffreichen Ernährung halten Sie das Mikrobiom und Ihren Darm gesund. Um sich zu regenerieren, benötigt unser Darm Pausen. Empfehlenswert sind dreistündige Esspausen zwischen den Mahlzeiten, aber auch Intervallfasten oder Fasten allgemein unterstützt die Regeneration des Darms. Die 100-Jährigen in Japan essen nach dem Prinzip „Hara hachi bu“. Dahinter verbirgt sich die darmgesunde Regel, nur so viel zu essen, bis der Magen zu 80 Prozent gefüllt ist. Lassen Sie Lebensmittel weg, die Sie schlecht vertragen.
-
Ganze Lebensmittel Ein ganzes Dinkelkorn löst in unserem Körper eine völlig andere Reaktion aus als ein helles Weißmehlbrötchen. Auch eine frische Beere wirkt anders als das gezuckerte Erdbeerpüree im Fruchtjoghurt, ein Stück Fleisch anders als eine Scheibe Mortadella und frisches Olivenöl anders als gehärtete Industriefette. Je naturbelassener unsere Lebensmittel sind, umso wertvoller und nährstoffreicher sind sie für uns. Egal welche Ernährungsform Sie bevorzugen: Die Menge an ganzen, unverarbeiteten Lebensmitteln ist ein gutes Maß, um verschiedene Ernährungsweisen zu beurteilen.
-
Täglich LaVita als Basis LaVita unterstützt uns täglich mit allen wichtigen Vitaminen und Spurenelementen, gerade dann, wenn unsere Ernährung nicht immer optimal ist oder ein erhöhter Bedarf durch Stress oder Medikamente besteht. Viele Ernährungsexperten wie Prof. Walter Willett von der Harvard University raten im Hinblick auf unsere Ernährungsgewohnheiten zusätzlich zu einer täglichen Mikronährstoffergänzung.
-
Trinken bevor der Durst kommt Der Mensch besteht zu 80 Prozent aus Wasser. Nichts ist wichtiger für uns. Wasser ist ein entscheidendes Transportmittel, das Nährstoffe zu unseren Zellen transportiert. Moderate Mengen Kaffee oder koffeinhaltigen Tee können Sie zur Flüssigkeitszufuhr dazuzählen. Viele machen sich um Ihre Wasserzufuhr wenig Gedanken. Mit wie viel Wasser am Tag fühlen Sie sich wohl? 1,5 bis 2 Liter pro Tag sind ein guter Richtwert.

Daily goals for a healthy feeling
Gesunde Ernährung im Alltag – Top-Tipps
- Starten Sie mit drei festen Mahlzeiten pro Tag – mit Pausen von jeweils 4 Stunden.
- Essen Sie zu einer Mahlzeit Obst (z. B. Frühstück) und zu den anderen beiden Mahlzeiten Gemüse.
- Freunden Sie sich mit Hülsenfrüchten an: Essen Sie mehrmals pro Woche eine Handvoll.
- Täglich eine Handvoll Nüsse – im Müsli, im Salat oder als Topping.
- Optimieren Sie Ihre Mikronährstoffzufuhr, wenn Sie es nicht immer schaffen, ausgewogen zu essen oder wenn Sie durch Belastungen oder Medikamenteneinnahme einen erhöhten Bedarf haben.
Psychisch
- Führen Sie eine Morgenroutine ein: Diese Zeit am Morgen gilt allein Ihren Interessen und Bedürfnissen.
- Tragen Sie Ihre Hobbys fest in den Terminkalender mit ein.
- Belohnen Sie sich für gemeisterte, schwierige Aufgaben und gönnen Sie sich aktiv Pausen.
- Fördern Sie positive soziale Kontakte: Verbringen Sie wöchentlich Zeit mit Personen, die Ihnen Energie schenken und Sie inspirieren.
- Achten Sie auch hier auf eine gesunde Ernährung und gute Mikronährstoffzufuhr: Biotin, Jod, Kupfer, Magnesium, Vitamin C und viele B-Vitamine tragen zu einer normalen Funktion des Nervensystems bei und die B-Vitamine unterstützen auch die normale psychische Funktion.

- La Maddalena Archipelago: A hidden gem with stunning beaches and clear waters, perfect for snorkeling and diving.
- Bosa: A picturesque town known for its colorful houses, medieval castle, and riverside setting.
- Gola su Gorropu: Europe’s deepest gorge, offering spectacular hiking opportunities amid dramatic limestone cliffs.
- Isola dell’Asinara: A national park with pristine beaches and wild landscapes, once home to a high-security prison.
- Orgosolo: Famous for its murals depicting social and political themes, providing insight into Sardinian culture and history.
Secrets:
- Su Nuraxi di Barumini: While not exactly a secret, this UNESCO-listed nuragic complex is often overlooked by tourists but offers a fascinating glimpse into Sardinia’s ancient past.
- Nuraghe Santu Antine: Another impressive nuraghe site, often less crowded than Su Nuraxi but equally captivating.
- Tiscali: A hidden archaeological site accessible via a scenic hike, featuring a well-preserved nuragic village inside a limestone cave.
- Spiaggia del Principe: Although it’s gaining popularity, this stunning beach on the Costa Smeralda still feels relatively secluded compared to other nearby beaches.
- Monte Arci: A volcanic massif dotted with ancient mines and archaeological sites, offering excellent hiking opportunities and panoramic views.
Tips:
- Rent a Car: While public transportation is available, renting a car allows you to explore remote areas and hidden gems at your own pace.
- Visit in the Shoulder Seasons: Avoid the peak summer months if possible (July and August) to experience fewer crowds and more comfortable temperatures.
- Try Local Cuisine: Don’t miss the opportunity to sample traditional Sardinian dishes like pane carasau (crispy flatbread), malloreddus (Sardinian gnocchi), and seadas (cheese-filled pastries).

Recommendations from Amanda Perino
Practical tips
- Earplugs are always a good idea, no matter where you are staying. Amsterdam is an old city, and very compact. This means insulation is often poor, and the streets are loud.
- Don’t walk in the bike lane. For the love of all that is holy, do not walk on or cross the bike lanes without looking at least two or three times, both ways.
- If you rent a bike, treat the bike bell like a car horn, not like a fun toy. Use only when needed.
- Tipping in Amsterdam is becoming more popular, but is not required. It is customary to round a bill up if you do want to leave a tip. For instance, if your bill for food and drink comes to 65 euro, you might leave 70 euro. It is not usual to tip on just a drink order at a bar.
Eat
Booking ahead is always recommended!
Casual/mid-range:
- The Lobby Nesplein- nice for lunch or dinner. Cozy, intimate, and classy. Close to Dam Square and the Rails World venue.
- Vessel- set in a beautiful hotel (Boat & Co) overlooking the harbor in the West. Note from Amanda: I go here to co-work pretty often, just because I like the space.
- Wilde Zwijnen- cozy, chef’s menu, seasonal
- Foodhallen- Very popular hipster food hall, but lots of variety at the many stalls. But good luck finding a table! (and keeping it). (No need to book ahead here.)
- Maydanoz turkish restaurant
When you want to spend a little more on the experience:
- Choux- Amanda’s personal favorite. They put a lot of care into their dishes and it shows. Heavy on the fish/seafood/vegetables.
- Wolf Atelier - when you’re thinking ‘I could really go for 15 courses right about now…’
For those who brunch:
- Cut Throat- because you can get brunch and a haircut at the same time (but I just love the space itself).
- Dignita- There are 3 in the city, so take your pick.
Drink: coffee
Amsterdam looooooooves coffee so there are a ton of great coffee places in the city, and you never have to go far to find the good stuff. Here are a few options depending on where you are in the city.
- Lot 61- near the Kinkerstraat
- Back to Black- near the Leidseplein/Rijsmuseum
- Toki- near the Haarlemmerstraat
- Hummingbird- near the Spui/Dam/Rokin
- Monk’s- near De Clerqstraat
Drink: alcohol
If you like natural wines and slightly more intimate vibes:
If you don’t mind a (younger) crowd and ordering at the bar:
If you like beer:
- Brouwerij t’Ij- local brewery with tasting room right under a windmill. Can’t get more Dutch than that.
- Gollem- there are a couple in the city, and all have a massive selection of beers from the NL and Belgium and further abroad.
Proeflokaal:
- Try genever at one of the fun old proeflokalen in the city. Wynand Fockink is by Dam Square and can be crowded and touristy, but also very fun.
Bruin cafes:
- Dutch brown bars are small, cozy, fun, and historic. Grab a vaasje (small beer), kaasblokjes (cheese blocks), and get a feel for what ‘gezellig’ truly means. Het Papeneiland, Cafe ‘t Smalle, Cafe Chris, and De Sluyswacht, to name a few.
- If you like cocktails: Note from Amanda: I am not a fan of cocktails, but if you are going to go, these are the best spots.
- Hiding in Plain Site
- Tales & Spirits
- Rosalie’s Menagerie
See/Do
- Noordermarkt (market) - a fun Saturday market in the Jordaan to browse food, antiques, and people. From 9am to 3pm.
- Boating on the canals- Amsterdam by water is the very best. Three options:
-
- Big boat tours. They leave from Central Station, but are impersonal and touristy.
-
- If you don’t want to drive or want more people onboard and are willing to pay more for someone else to drive, try: boatnow Don’t forget to invite your good pal Amanda P.
- Kuuma sauna- private sauna for you and friends, with a fun view overlooking the old ship in Marrineterrein. (Amsterdam location should be available to book again in October.) Tip: No hot showers on site, so plan to head to your hotel after before going elsewhere.
- Mooie Boules- whether you call it petanque or boules, this is a fun bar with boules fields inside. Best to book your field ahead.
- TonTon Club - a barcade in Westerpark with pub food, drinks, and an upstairs with lots of fun games.
- Duke of Tokyo- karaoke bar with private rooms set up like a narrow alley in Tokyo. Fun vibes. It’s popular, so booking ahead is advised.
Museums
-
Rijksmuseum- go for the masterpieces, stay for the building/architecture, and make sure to catch the detailed paintings of the ships at sea mid-battle (Amanda’s personal favorite).
-
Het Scheepsvaartmuseum & VOC Schip Amsterdam- Note from Amanda: The National Maritime Museum probably isn’t high on many people’s lists, but with the architecture of the building itself, the amazing collection of ship battle scenes, and the reproduction of the wooden ship outside, it hits all the right notes for me (nerd alert!). I think it’s pretty cool and very Dutch.

3 Mäuse
Drei Mäuse sitzen an der Bar und protzen damit, wer von ihnen die coolste ist. Die Erste sagt: “Wenn ich eine Mausefalle sehe, nehme ich mit der linken Hand den Käse raus. Mit der rechten fange ich den Bügel ab und mache vor dem Essen noch etwas Krafttraining”. Die Zweite: “Wenn bei uns Rattengift gestreut wird, nehme ich mir eine Rasierklinge, hacke den Stoff klein, lege eine Linie und zieh mir das Zeug durch die Nase.” Die dritte Maus steht auf und geht. “Hat’s Dir die Sprache verschlagen?” fragen die Mäuse. “Ihr langweilt mich”, sagt die Dritte. “Ich geh nach Hause, die Katze ficken.”
Uwe
Ein Mann kommt in ein kleines Lokal und fragt: “Habt ihr hier auch Nutten?” Sagt der Wirt: “Nee, wir haben nur unseren Uwe.” Guckt der Mann etwas verwirrt und meint dann: “Egal, ich bin so geil, ich brauche jetzt unbedingt Sex. Was kostet das denn?” “80€”, sagt daraufhin der Wirt. “OK. Und wie läuft das dann ab? Ich geb dem uwe die 80 € und dann wird gebumst?” “Nein, nicht ganz”, sagt der Wirt. “40 € bekommt unser Bürgermeister. Es ist sein Dorf und er hat es eigentlich nicht so gerne. So ist er beruhigt und sagt auch nix.” “OK, egal. Dann bekommt der Uwe eben 40€.” “Auch nicht”, sagt der Wirt. 20 € bekomme ich. Das hier ist mein Gasthaus und ich hab das auch nicht so gerne.“ “Soll mir auch recht sein”, sagt der Mann. “Bekommt der Uwe eben nur 20€.” “Auch falsch,” sagt der Wirt. “Die letzten 20€ teilen sich Michael und Rainer. Die halten Uwe fest. Der hat das nämlich auch nicht so gerne.”

A poem on our journey in ireland, the bus driver bud wishes a poem from her adventurers.
living in the wild like a sheep alongside are the cliffs so deep Sitting in the bus listening to Bud’s stories Makes you feel like there are no worries And all you want is this to keep.
All those greyish stones around Standing together on the ground Walls builded by the people In the back a steeple And the wind makes a sad sound.
To the cliffs from east to the west the guide bud does all the best tells us lots of funny stories creates for us some new memories One thing learned again: never rest
Der Panther
Im Jardin des Plantes, Paris
Sein Blick ist vom Vorübergehn der Stäbe so müd geworden, dass er nichts mehr hält. Ihm ist, als ob es tausend Stäbe gäbe und hinter tausend Stäben keine Welt.
Der weiche Gang geschmeidig starker Schritte, der sich im allerkleinsten Kreise dreht, ist wie ein Tanz von Kraft um eine Mitte, in der betäubt ein großer Wille steht.
Nur manchmal schiebt der Vorhang der Pupille sich lautlos auf -. Dann geht ein Bild hinein, geht durch der Glieder angespannte Stille - und hört im Herzen auf zu sein.
Rainer Maria Rilke, 6.11.1902, Paris

Quotes
Sadhguru
Elternschaft ist schon eine lustige Sache. Du versuchst etwas zu tun, von dem niemand jemals wusste, wie man es richtig macht. Aber du willst dein Bestes geben! Also was kannst du am besten tun? Das Erste ist, ein wenig an sich selbst zu arbeiten. Verbringe genügend Zeit mit dir selbst. Schau dich genau an: Wie du bist, wie du sitzt, wie du stehst, wie du sprichst, was du machst, was du nicht machst. Ich denke, man muss sich selbst sehr genau betrachten. Denn die Kinder erfassen alles schnell und sie werden das, was du tust, verstärken. Eines der wichtigsten Dinge ist, sich zumindest so zu gestalten, wie man sein möchte. Jemand ist damit vielleicht nicht einverstanden. Das ist egal! Zumindest hast du versucht so zu sein, wie du dich magst. Das ist das Mindeste, was du tun kannst. Vielleicht erfüllst du die Erwartungen anderer nicht. Wir wissen nicht, was andere für Wertvorstellungen haben. Aber wenigstens musst du so werden, wie du dich magst.
Nicholas Rockefeller
Der Feminismus ist unsere Erfindung aus zwei Gründen. Vorher zahlte nur die Hälfte der Bevölkerung Steuern, jetzt fast alle weil die Frauen arbeiten gehen. Außerdem wurde damit die Familie zerstört und wir haben dadurch die Macht über die Kinder erhalten. Sie sind unter unserer Kontrolle mit unseren Medien und bekommen unsere Botschaft eingetrichtert, stehen nicht mehr unter dem Einfluss der intakten Familie. In dem wir die Frauen gegen die Männer aufhetzen und die Partnerschaft und die Gemeinschaft der Familie zerstören, haben wir eine kaputte Gesellschaft aus Egoisten geschaffen, die arbeiten (für die angebliche Karriere), konsumieren (Mode, Schönheit, Marken), dadurch unsere Sklaven sind und es dann auch noch gut finden.
Ralph Waldo Emerson
Das Wissen, dass mindestens eine Person dank deiner Existenz ein besseres Leben hatte. Das bedeutet Erfolg.
Steve Jobs
Die Leute, die so verrückt sind zu glauben, dass sie die Welt verändern können, sind diejenigen, die es tun.

Productivity
7 productivity recommendations by @elonmusk (confirmed)
- Excessive meetings are the blight of big companies and almost always get worse over time. Please get of all large meetings, unless you’re certain they are providing value to the whole audience in which case keep them very short.
- Also get rid of frequent meetings, unless you are dealing with an extremely urgent matter. Meeting frequency should drop rapidly once the urgent matter is resolved.
- Walk out of a meeting or drop off a call as soon as it is obvious you aren’t adding value. It is not rude to leave, it is rude to make someone stay and waste their time.
- Don’t use acronyms or nonsense words for objects, software or processes at Tesla. In general, anything that requires an explanation inhibits communication. We don’t want people to have to memorize a glossary just to function at Tesla.
- Communication should travel via the shortest path necessary to get the job done, not through the “chain of command”. Any manager who attempts to enforce chain of command communication will soon find themselves working elsewhere.
- A major source of issues is poor communication between depts. The way to solve this is allow free flow of information between all levels. If, in order to get something done between depts, an individual contributor has to talk to their manager, who talks to a director who talks to a VP, who talks to another VP, who talks to a director, who talks to a manager, who talks to someone doing the actual work, then super dumb things will happen. It must be ok for people to talk directly and just make the right thing happen.
- In general, always pick common sense as your guide. If following a “company rule” is obviously ridiculous in a particular situation, such that it would make for a great Dilbert cartoon, then the rule should change.

Progress, Precision and Profit
Everybody
Progress
First, congratulations are in order! We have now completed our third full week of producing over 2000 Model 3 vehicles. The first week was 2020, the second was 2070 and we just completed 2250 last week, along with 2000 Model S/X vehicles.
This is more than double Tesla’s weekly production rate last year and an amazing feat in the face of many challenges! It is extremely rare for an automotive company to grow the production rate by over 100% from one year to the next. Moreover, there has simultaneously been a significant improvement in quality and build accuracy, which is reflected in positive owner feedback.
Starting today at Giga and tomorrow at Fremont, we will be stopping for three to five days to do a comprehensive set of upgrades. This should set us up for Model 3 production of 3000 to 4000 per week next month.
Another set of upgrades starting in late May should be enough to unlock production capacity of 6000 Model 3 vehicles per week by the end of June. Please note that all areas of Tesla and our suppliers will be required to demonstrate a Model 3 capacity of ~6000/week by building 850 sets of car parts in 24 hours no later than June 30th.
Any Tesla department or supplier that is unable to do this will need to have a very good explanation why not, along with a plan for fixing the problem and present that to me directly. If anyone needs help achieving this, please let me know as soon as possible. We are going to find a way or make a way to get there.
The reason that the burst-build target rate is 6000 and not 5000 per week in June is that we cannot have a number with no margin for error across thousands of internally and externally produced parts and processes, amplified by a complex global logistics chain. Actual production will move as fast as the least lucky and least well-executed part of the entire Tesla production/supply chain system.
By having a Model 3 subsystem burst-build requirement of 6k by the end of June, we will lay the groundwork for achieving a steady 6k/week across the whole Model 3 system a few months later.
As part of the drive towards 6k, all Model 3 production at Fremont will move to 24/7operations. This means that we will be adding another shift to general assembly, body and paint. Please refer anyone you know who you think meets the Tesla bar for talent, drive and trust. Between Fremont and Giga, Tesla will be adding about 400 people per week for several weeks.
Precision
Most of the design tolerances of the Model 3 are already better than any other car in the world. Soon, they will all be better. This is not enough. We will keep going until the Model 3 build precision is a factor of ten better than any other car in the world. I am not kidding.
Our car needs to be designed and built with such accuracy and precision that, if an owner measures dimensions, panel gaps and flushness, and their measurements don’t match the Model 3 specs, it just means that their measuring tape is wrong.
Some parts suppliers will be unwilling or unable to achieve this level of precision. I understand that this will be considered an unreasonable request by some. That’s ok, there are lots of other car companies with much lower standards. They just can’t work with Tesla.
Profit
A fair criticism leveled at Tesla by outside critics is that you’re not a real company unless you generate a profit, meaning simply that revenue exceeds costs. It didn’t make sense to do that until reaching economies of scale, but now we are there.
Going forward, we will be far more rigorous about expenditures. I have asked the Tesla finance team to comb through every expense worldwide, no matter how small, and cut everything that doesn’t have a strong value justification.
All capital or other expenditures above a million dollars, or where a set of related expenses may accumulate to a million dollars over the next 12 months, should be considered on hold until explicitly approved by me. If you are the manager responsible, please make sure you have a detailed, first principles understanding of the supplier quote, including every line item of parts & labor, before we meet.
I have been disappointed to discover how many contractor companies are interwoven throughout Tesla. Often, it is like a Russian nesting doll of contractor, subcontractor, sub-subcontractor, etc. before you finally find someone doing actual work. This means a lot of middle-managers adding cost but not doing anything obviously useful. Also, many contracts are essentially open time & materials, not fixed price and duration, which creates an incentive to turn molehills into mountains, as they never want to end the money train.
There is a very wide range of contractor performance, from excellent to worse than a drunken sloth. All contracting companies should consider the coming week to be a final opportunity to demonstrate excellence. Any that fail to meet the Tesla standard of excellence will have their contracts ended on Monday.
Btw, here are a few productivity recommendations:
– Excessive meetings are the blight of big companies and almost always get worse over time. Please get of all large meetings, unless you’re certain they are providing value to the whole audience, in which case keep them very short.
– Also get rid of frequent meetings, unless you are dealing with an extremely urgent matter. Meeting frequency should drop rapidly once the urgent matter is resolved.
– Walk out of a meeting or drop off a call as soon as it is obvious you aren’t adding value. It is not rude to leave, it is rude to make someone stay and waste their time.
– Don’t use acronyms or nonsense words for objects, software or processes at Tesla. In general, anything that requires an explanation inhibits communication. We don’t want people to have to memorize a glossary just to function at Tesla.
– Communication should travel via the shortest path necessary to get the job done, not through the “chain of command”. Any manager who attempts to enforce chain of command communication will soon find themselves working elsewhere.
– A major source of issues is poor communication between depts. The way to solve this is allow free flow of information between all levels. If, in order to get something done between depts, an individual contributor has to talk to their manager, who talks to a director, who talks to a VP, who talks to another VP, who talks to a director, who talks to a manager, who talks to someone doing the actual work, then super dumb things will happen. It must be ok for people to talk directly and just make the right thing happen.
– In general, always pick common sense as your guide. If following a “company rule” is obviously ridiculous in a particular situation, such that it would make for a great Dilbert cartoon, then the rule should change.
If there is something you think should be done to make Tesla execute better or allow you to look forward to coming to work more (same thing in the long term), please send a note to [redacted]
Thanks for being such a kickass team and accomplishing miracles every day. It matters. We are burning the midnight oil to burn the midnight oil.
