A notable example that comes to mind is my time in Uruguay, where I found myself aligning more closely with the conservative party. In contrast, during my experiences in the US, I’ve discovered that my views resonate more with the progressive party. This shift in perspective has taught me that it’s not about identifying with a particular ideology or party affiliation, but rather about embracing a set of core values that can be applied flexibly across different contexts.

The epiphany:

This epiphany has led me to develop a framework for approaching my own beliefs, one that has significantly impacted my thought process on various topics. I’ve come to realize that issues like abortion, homosexuality, and religion require a nuanced and multi-faceted approach, one that takes into account the intricacies of human experience and the complexities of societal norms.

As I’ve navigated this journey of self-discovery, I’ve also come to understand that humans are inherently flawed. We’re complex beings, driven by a mix of emotions, experiences, and biases. This realization has been incredibly liberating, as it’s allowed me to approach conversations and relationships with empathy and compassion. I’ve learned to see that people’s opinions and beliefs are often shaped by their unique experiences and perspectives, rather than being simply right or wrong.

This mindset shift has brought a tremendous amount of positivity into my life. By recognizing the gray areas between black and white, I’ve been able to engage in more meaningful conversations and build deeper connections with others. I’ve learned to listen actively, seeking to understand the underlying values and experiences that shape people’s perspectives. This, in turn, has helped me to become a more empathetic and open-minded individual.

The Benefit:

One of the most significant benefits of this mindset shift has been the ability to see multiple sides of an issue. I no longer feel constrained by binary thinking, where every topic is reduced to a simple yes or no, or right or wrong. Instead, I’ve come to understand that most issues exist on a spectrum, with nuances and complexities that require careful consideration.

For instance, when discussing topics like social justice, I’ve learned to recognize the historical and systemic contexts that shape our current reality. I’ve come to see that these issues are not simply matters of individual morality, but rather complex problems that require a comprehensive understanding of power dynamics, institutional structures, and cultural norms.

Similarly, when engaging with individuals who hold differing views, I’ve learned to approach conversations with curiosity and empathy. Rather than trying to “win” an argument or convince someone of my perspective, I seek to understand the underlying values and experiences that shape their beliefs. This has allowed me to build bridges across ideological divides, fostering a sense of community and shared humanity.

According to Dr. Brené Brown, a research professor at the University of Houston, “Vulnerability is the birthplace of love, belonging, and creativity” (Brown, 2012). By embracing our flaws and vulnerabilities, we can create space for deeper connections and more meaningful relationships.

As I continue on this path of self-discovery, I’m reminded of the importance of maintaining a balance between conviction and open-mindedness. It’s a delicate tightrope to walk, but one that ultimately allows for a more authentic and compassionate engagement with the world around me.

I’d love to hear from you – how have your experiences shaped your personal values and beliefs? What frameworks or approaches have you developed to navigate complex issues, and how do you strive to maintain a balance between conviction and open-mindedness?

If you’d like to see the framework, check my other post:

I never thought I’d be the type of person to own a 3D printer, but life has a way of surprising us, doesn’t it? One day, I found myself intrigued by the idea of learning something new, and before I knew it, I was diving headfirst into the world of 3D printing.

As I began to research and explore my options, I realized that buying a pre-assembled printer might not be the best choice for me. I wanted to understand the inner workings of this technology, and what better way to do that than to build it myself? My brother, an expert in the field (check out his work at www.armorbionics.com ), was more than happy to guide me through the process.

After careful consideration, I decided on the Crealty Ender 3 v2. The assembly process was relatively straightforward, and I was relieved to find that it worked beautifully right from the start. To ensure I didn’t miss any crucial steps, I followed a YouTube assembly video – always better to be safe than sorry, right?

As I delved deeper into the world of 3D printing, I discovered a community that’s passionate, innovative, and always eager to share knowledge. From troubleshooting common issues to experimenting with new materials and designs, there’s no shortage of exciting projects to tackle.

So, what sparked my interest in 3D printing?

For me, it was the desire to learn something new and challenge myself. But I’m curious – what about you? Have you ever considered exploring the world of 3D printing? Perhaps you’ve already taken the plunge and have some amazing projects to share?

Let’s start a conversation!

What drew you to 3D printing, or what’s holding you back from giving it a try? Share your thoughts, experiences, and questions in the comments below. Let’s learn from each other and discover the endless possibilities that 3D printing has to offer.

I was not planning on buying a 3D Printer, but… over time I realized it’d be a good idea to learn something new.

One thing led to another and I ended up building the whole set.

The printer

I didn’t want to buy something crazy and super expensive off the bat, so I researched, spoke to my brother (www.armorbionics.com) and decided on an Crealty Ender 3 v2.

The assembly was easy enough, right off the bat worked pretty well. I did use a youtube assembly video just to make sure I don’t screw it up, there’s a few

Let’s get 3 things so we can ease future pain, one is Ansible, second Docker and lastly Kubernetes.

Ansible, quite straight forward:

Install Ansible:

# In case its a brand new VM
apt update

# Lets add Ansible Repo
echo "deb http://ppa.launchpad.net/ansible/ansible/ubuntu bionic main" | tee /etc/apt/sources.list.d/ansible.list
apt -y install gnupg2
apt-key adv --keyserver keyserver.ubuntu.com --recv-keys 93C4A3FD7BB9C367

# Lets get the new repo
apt update

# Lets install ansible
apt install -y ansible

# Check ansible is installed.
ansible --version
ansible 2.8.6
  config file = /etc/ansible/ansible.cfg
  configured module search path = [u'/home/debian/.ansible/plugins/modules', u'/usr/share/ansible/plugins/modules']
  ansible python module location = /usr/lib/python2.7/dist-packages/ansible
  executable location = /usr/bin/ansible
  python version = 2.7.16 (default, Apr  6 2019, 01:42:57) [GCC 8.3.0]

Lets go over the details of ansible, later.

Install Docker:

# In case youre doing it wrong
apt update

# Install requirements, again, in case you're skipping ansible
apt -y install apt-transport-https ca-certificates curl gnupg2 software-properties-common

# Lets add the key
curl -fsSL https://download.docker.com/linux/debian/gpg | apt-key add -

# Lets add the repo
add-apt-repository \
   "deb [arch=amd64] https://download.docker.com/linux/debian \
   $(lsb_release -cs) \

# Classic update to fetch new repo
apt update

# Install docker
apt -y install docker-ce docker-ce-cli containerd.io

# Add user and group

If that worked, then you can test if you wish it's working?



If you were able to reproduce this on the screen, you should be good.

Install NodeJS:

curl -sL https://deb.nodesource.com/setup_15.x | bash -
apt-get install -y nodejs
npm install npm --global

Since we got this far, lets make our lives easier and get Ansible AWX installed.

apt -y install python3-pip git pwgen vim  python3-docker 
pip3 install requests==2.14.2
update-alternatives --install /usr/bin/python python /usr/bin/python2.7 1
update-alternatives --install /usr/bin/python python /usr/bin/python3 2

# MATCH DOCKER COMPOSE VERSIONS!

pip3 install docker-compose==1.24.1

# Clone the repo
su -
git clone --depth 50 https://github.com/ansible/awx.git
cd awx/installer/
# Customize
vim inventory
# Lets generate a password
pwgen -N 1 -s 30
KEY

Fix inventory

dockerhub_base=ansible
awx_task_hostname=awx
awx_web_hostname=awxweb
postgres_data_dir=/tmp/pgdocker
host_port=80
host_port_ssl=443
docker_compose_dir=/tmp/awxcompose

create_preload_data=True
secret_key=KEY

Lets run that playbook!

ansible-playbook -i inventory install.yml

Now you can access the web on the host and port in inventory. At the folder:

cd ~/.awx/awxcompose/

Stop docker

docker-compose stop
Stopping awx_task      ... done
Stopping awx_web       ... done
Stopping awx_rabbitmq  ... done
Stopping awx_postgres  ... done
Stopping awx_memcached ... done

Lets pull new images:

docker-compose pull
Pulling rabbitmq  ... done
Pulling memcached ... done
Pulling postgres  ... done
Pulling web       ... done
Pulling task      ... done

Lets re-start it, and with that we have full loop!

docker-compose up --force-recreate -d
Recreating awx_postgres  ... done
Recreating awx_rabbitmq  ... done
Recreating awx_memcached ... done
Recreating awx_web       ... done
Recreating awx_task      ... done

Last step!

Kubernetes!

# We need to enable bridge netfilter
modprobe br_netfilter;
echo 'net.bridge.bridge-nf-call-iptables = 1' > /etc/sysctl.d/20-bridge-nf.conf;
sysctl --system;

Lets take some other steps in case you're ignoring the rest.

# install tools for adding apt sources
apt-get update;
apt-get install -y \
  apt-transport-https \
  ca-certificates \
  curl \
  gnupg2;

If you already installed docker, ignore this step:

# install docker
mkdir /etc/docker;
cat > /etc/docker/daemon.json <<EOF
{
  "exec-opts": ["native.cgroupdriver=systemd"],
  "log-driver": "json-file",

apt-get update;
apt-get install -y --no-install-recommends docker-ce;

Finally, Kubernetes time!

Perfect, now we have access to kubernetes, now lets make the access public on port 8001.

kubectl -n kubernetes-dashboard edit service kubernetes-dashboard

Let’s see the services running in the context of our dashboard.

kubectl -n kubernetes-dashboard get services

Let’s get the port being used:

kubectl -n kubernetes-dashboard get services
NAME TYPE CLUSTER-IP EXTERNAL-IP PORT(S) AGE
kube-dns ClusterIP 10.96.0.10 [none] 53/UDP,53/TCP 20d
kubernetes-dashboard NodePort 10.107.194.201 [none] 443:32414/TCP 20d

Let’s check it’s listening.

lsof -i tcp:32414
COMMAND PID USER FD TYPE DEVICE SIZE/OFF NODE NAME
kube-prox 3440 root 7u IPv6 32584 0t0 TCP *:32414 (LISTEN)

Let’s get the token if needed and other info.

kubectl -n kube-system describe $(kubectl -n kube-system get secret -n kube-system -o name | grep namespace) | grep token:

Lets add some storage…

mkdir -p /mnt/pv{1,2}
kubectl create -f - <<EOF
kind: PersistentVolume
apiVersion: v1

If we want to see our storage:

kubectl get pvc

This should be enough to start…. we’ll add more in a new post!

As someone who has spent countless hours managing servers, I’ve often found myself in situations where copying and pasting passwords or commands just doesn’t work. Whether it’s logging into a server via VNC or using lights-out management tools, there are times when typing is the only option. And let’s be honest, who likes typing out complex passwords or commands?

That’s where AutoHotKey comes in – a powerful scripting language that can automate tasks and make our lives easier. One of its most useful features is the ability to type out the contents of our clipboard using a simple hotkey. This can save us a significant amount of time and frustration, especially when working with sensitive information.

The Solution: AutoHotKey Script

To get started, you’ll need to create an AutoHotKey script that types out the contents of your clipboard. Here’s a sample script to get you started:

Script:

#NoEnv          ; Recommended for performance and compatibility with future AutoHotkey releases.
SendMode Input  ; Recommended for new scripts due to its superior speed and reliability.

^+v::Send {Raw}%Clipboard%

This script uses the Ctrl + Shift + V hotkey to type out the contents of your clipboard. You can customize this hotkey to suit your needs, but the basic idea remains the same.

The Easy Way Out: Pre-Built Executable

If setting up AutoHotKey and creating a script from scratch sounds like too much work, don’t worry! You can download a pre-built executable that includes this functionality. Simply run the executable, and you’ll have access to the Ctrl + Shift + V hotkey to type out your clipboard contents.

Actionable Insights:

1. Save time: By automating tasks like typing out passwords or commands, you can free up more time for critical server management tasks.
2. Reduce errors: With AutoHotKey handling the typing, you’ll reduce the likelihood of typos and other human errors that can lead to security issues or system downtime.
3. Improve productivity: By streamlining your workflow with tools like AutoHotKey, you can improve your overall productivity and focus on higher-priority tasks.

What’s Your Experience?

Have you ever found yourself in a situation where typing out passwords or commands was the only option? How did you handle it? Share your stories and tips for managing servers efficiently. Let’s start a conversation!

Sample:

Download the following exe.

When it’s time to type your keyboard content, press CNTRL+SHIFT+V to enjoy the contents being typed in.

Let’s say we already have this info; we want to be able to… I don’t know de-auth the device, so it’s like we manually disconnected it.
Assuming you have a device with idProduct 0610, do the following:

grep 0610 /sys/bus/usb/devices/*/idProduct
/sys/bus/usb/devices/1-2.4/idProduct:0610

Same if you have an idVendor:

grep 05e3 /sys/bus/usb/devices/*/idVendor
/sys/bus/usb/devices/1-2.4/idVendor:0610

Perfect, you found the path to your device under sys… now lets look at lsusb.

lsusb way… the hard way.

I have to admit it’s exciting until you’re done playing with their coding challenges. I did 3, okay, I didn’t kill myself over them, but it was to check it out. It’s 5:18 in the morning, and I couldn’t fall asleep, so I decided to check what’s up in the remote job land.

Anyways, my opinion?

The website seems sleek very minimal, sadly takes a long time to load. The first time you load the page, you’re hit with pointless “coolio” animations that didn’t add much… other than the suspense, of course.

Thinking it was slow just for me, I found other people complaining about the same thing, so I decided to check out if it’s quiet for us two, or more people.

Lets see how long it takes for Pingdom to get the website from their San Francisco server.

Okay, 702 ms plus the animation there we go. At least I know it’s not just me, it’s slow.

Why is it taking so long to start downloading?

117 ms on DNS… interesting, they are using cloudflare.

Regardless, the tests were fun, but when I got the “test” and saw it was like 40 hours, I decided… maybe I can do it quicker…

Well, no. It’s very vague, doesn’t contain too many guidelines it’s up to you to do everything, so I have to admit getting just an email and google docs specifying what needed to be done was an instant-turnoff. The website needs a lot of love and polishing if they plan on competing with market leaders, you know, toptal, and others.

Kudos to you guys, at least the tests were fun for tonight. Hopefully, in the future, we’ll see the website blossom, and maybe their competitors will fear them?

That’s all for now, I’m not posting the challenges so at least I leave some mystery behind.
