Setting up Nginx on Ubuntu (18+) with Let’s Encrypt SSL ensures that your website or application is secure and accessible over HTTPS, providing a safe browsing experience for your users. This process not only includes the installation of the Nginx web server but also entails configuring the server to handle SSL certificates issued by Let’s Encrypt, enabling automatic renewal of these certificates to maintain uninterrupted security. By following best practices for security and performance, you can optimize your server’s settings to ensure fast loading times and reliable uptime, which are crucial for retaining visitors and improving search engine rankings. Additionally, implementing SSL helps to build trust with your audience, as it demonstrates a commitment to protecting their data and enhancing their online safety.
In this guide, we will:
Install and configure Nginx.
Set up port forwarding for your Node.js application.
Obtain a free SSL certificate from Let’s Encrypt.
Ensure proper firewall and AWS security group settings.
We all know sleep is important, but few of us truly grasp just how critical it is to our overall wellbeing. According to a landmark study published in the journal Science, sleep deprivation is linked to a 10-30% increase in mortality risk. Research has demonstrated that even a single night of inadequate sleep can reduce immune function by up to 70%, while chronic sleep deprivation has been directly linked to increased risk of diabetes, cardiovascular disease, and Alzheimer’s.
Perhaps most striking is a 2017 study published in Nature showing that after just one night of less than six hours of sleep, the body shows measurable signs of metabolic dysfunction, with over 700 genetic changes occurring. Sleep isn’t just about feeling rested—it’s a fundamental biological necessity for cellular repair, memory consolidation, and emotional regulation.
Speeding up Node or React build times on an EC2 instance involves optimizing your build process, leveraging the instance’s resources efficiently, and potentially tweaking your environment. Below are practical steps to reduce build times:
What do you wish a new full-stack developer to do before their first day to ensure a smooth onboarding experience?
We’d like you to review and strengthen your knowledge in the following key areas. This guide includes recommended resources and specific focus points for each technology.
When working with Large Language Models (LLMs) in a chat interface, understanding how to effectively communicate and leverage their capabilities can significantly improve your results. This involves crafting clear and specific prompts, providing necessary context, and breaking down complex tasks into manageable steps. It’s important to recognize that while LLMs possess vast knowledge, they require precise guidance to deliver optimal outputs. Users should be prepared to iterate on their queries, refine their instructions, and engage in a collaborative back-and-forth to achieve desired outcomes. Additionally, being aware of the model’s limitations, such as potential biases or outdated information, allows users to critically evaluate responses and seek clarification when needed.
Btw, if you wish to save and improve your prompts over time – you can use your VScode editor or a platform like latitude.
Here are six essential tips to enhance your experience:

“If you seek tranquillity, do less.” – Marcus Aurelius
In a world that constantly demands more from us, Greg McKeown’s book Essentialism: The Disciplined Pursuit of Less offers a refreshing and counterintuitive approach to achieving success and fulfillment. I finished it last weekend and decided to try to create a summary so I could browse it in the future when people are pushing for ‘more.’
This interesting book challenges the notion that we can have it all and advocates for a more focused, deliberate way of living and working.
The Core of Essentialism
At its heart, essentialism is about doing less but better.
Studying is an important and challenging task. In many cases, it won’t be fun. The primary feeling will be of an effort. It’s like this big ‘gym session’ that you hate. You are doing a mental effort equivalent to a physical one (=sweating). What’s even more tricky is to find what works best for you.
Let’s explore practical, real-world strategies to boost your study game. This post is based on Huberman’s outstanding research.

Ok, so it’s important to be agile.
Adaptability and rapid response to change are crucial in today’s fast-paced business environment. The pace and speed have increased by 10x (or more) with the new AI wave.
Agile methodology has emerged as a crucial approach for organizations looking to remain competitive and innovative. In this blog post, we will explore the importance of Agile, its main benefits, how to implement it effectively and provide a macro plan for executives. We will also delve into product strategy, goals, Objectives, and Key Results (OKRs) and offer eight practical tips for newcomers to Agile. Additionally, we’ll highlight some tools (that I used and liked) that can facilitate your Agile journey.
Why Agile is Important
Agile is a methodology centered around flexibility, collaboration, and customer-centricity. Unlike traditional project management approaches that rely on rigid, linear processes, Agile allows teams to adapt quickly to changes and deliver value incrementally. Btw, here is a good discussion on Agile Vs Waterfall.
In the fascinating realm of cryptocurrency, few names carry as much weight as Satoshi Nakamoto, the mysterious figure behind the creation of Bitcoin.
I did a short video about it a few years ago:
Satoshi’s contributions revolutionized how we perceive and engage with (digital) currency, yet much about this enigmatic persona remains mysterious. Among the many enigmas surrounding Satoshi, the allure of his lost emails captivates the imagination of crypto enthusiasts and historians alike.
The story begins with Satoshi Nakamoto’s groundbreaking whitepaper, published in 2008, which laid the foundation for Bitcoin. By the way, it’s the best paper I read. In 9 pages, you can gain much wisdom and even understand this complex technical, game theory, and economic brilliance. These nine pages created around 1 trillion dollars of value as of today.
Following this seminal document, Satoshi engaged in correspondence with a select group of individuals, sharing insights, exchanging ideas, and offering guidance on this cryptocurrency project.
However, the intrigue deepened as Satoshi’s correspondence abruptly ceased in 2011, leaving a void of silence that has puzzled researchers and historians ever since. The reasons behind this cessation remain a subject of speculation, ranging from personal reasons to concerns about legal implications and privacy.
Despite the veil of mystery surrounding Satoshi’s disappearance from the digital realm, the significance of his lost emails cannot be overstated. These messages provide a rare glimpse into the mind of the visionary creator who sparked a global financial revolution. Within the digital archives lie clues to Satoshi’s thought processes, motivations, and challenges in birthing Bitcoin into existence.
Understanding the context of Satoshi’s emails is essential for several reasons. First and foremost, they offer a unique perspective on the early days of Bitcoin’s development, shedding light on the technical intricacies, philosophical underpinnings, and ideological debates that shaped its evolution. I was smiling when they mentioned ‘sourceforge’ as GitHub started to go public around 2008, and we are talking about 2009 here.
Satoshi’s lost emails are a cautionary tale about the ephemeral nature of digital communication. In an era where digital footprints are meticulously tracked and archived, the disappearance of Satoshi’s correspondence underscores the impermanence of online interactions. It reminds us of the importance of preserving digital artifacts for posterity, ensuring that future generations can study and learn from the pioneers who paved the way for technological innovation.
Luckly, we just got 120 pages of emails that were just released from the early Bitcoin days.
The emails are 14+ years old and were sent between:
Martti Malmi who was an OG Bitcoin developer.
Satoshi Nakomoto the creator of Bitcoin.
Here are some of the interesting questions that these emails are answering:
