Graceful termination of pods in Kubernetes is essential to prevent data loss, minimize interruptions, and ensure services are stopped in a controlled manner. This process occurs when Kubernetes deletes a pod, whether due to a Deployment update, scaling, eviction for lack of resources, or when the user manually deletes the pod. Understanding how graceful termination works helps you design more robust applications.
When Kubernetes wants to terminate a pod, it gives it the opportunity to shut down gracefully.Read more...
There are four types of platforms:
Marketplaces: are sites that allow two parties to make transactions.
Real examples: Wallapop eBay Airbnb Base platforms: provide IT resources to start a project.
Real examples: Amazon Web Services (AWS) Microsoft Azure Google Cloud Platform Development platforms: allow you to develop better and faster.
Real examples: GitHub Heroku Vercel Business capability platforms: create an open ecosystem.
Real examples: Salesforce AppExchange Shopify App Store Apple App Store There can also be hybrid models that combine more than one type of platform.Read more...
Metabolism is about converting food into energy, and it does so through three main pathways:
the glucose pathway: the body processes carbohydrates and produces energy. This is the priority pathway for the brain and red blood cells—the former because of its importance, and the latter because they have no mitochondria.
the beta-oxidation pathway: it transforms fat into energy. When insulin drops, this pathway increases.
the ketosis pathway: it allows the energy from beta-oxidation to be distributed throughout the body in a context of low glucose.Read more...
We call Omega-3 and Omega-6 “essential fatty acids” because the body cannot produce them and needs to obtain them through food. One might ask why, if it’s such an essential element, evolution didn’t favor the selection of individuals capable of synthesizing it, but the way to think about it is the inverse: humans anciently had the capacity to synthesize it but precisely due to economy stopped doing so, optimized to obtain it from the environment where it was abundant at the time, and focused its investment on other more advantageous things.Read more...
David Whyte —marine biologist, poet, and philosopher (boom!)— has written about a concept that caught my attention: the conversational nature of reality. The idea is surprisingly intuitive: reality isn’t a solid block you push against in a single direction. It’s a series of exchanges in which you give and receive, and each interaction reshapes the world. Reality isn’t a problem waiting for a final solution, but a conversation that gradually reveals itself.Read more...
I wanted to stop showing in the frontpage of this blog powered by (Hugo) the posts tagged as “TIL” or “IWL”.
My theme template is
{{ $blogPages := where .Site.RegularPages.ByDate.Reverse ".Type" "in" .Site.Params.mainSections }} I tried with “intersect” and “where” but it did not work, not sure if it is because my Hugo version is old but, anyway, I was too lazy to upgrade Hugo (and adapt all templates, breaking changes, etc) so this simple code made my day:Read more...

This book is special because it contrasts Zen teachings with 1950s consumer America.

Knight trap in the Petrov Defense As an improving chess player, I’m always excited when I can execute a clean tactical sequence. Recently, I played a game where I was able to exploit one of the classic traps in the Petrov Defense. I’d like to share this experience and what I learned from it.

Fooled by randomness These are my notes for the book “Fooled by Randomness” by Nassim Taleb.
The thesis of the book is that when we look at the past we find things that are not there, the past is much more random than our vision. This is called the Hindsight bias. So we have to be aware that when people relate the past usually they tend to create post-hoc rationalizations and retrofitted explanations.Read more...
