The 5 Golden Rules of Data Visualization

Image
  Bad data visualizations are not just ugly. They are dangerous. A bad data visualization doesn’t just look unprofessional. It can make a good decision look bad, a small change look dramatic, or a serious problem look harmless. And the worst part? Most misleading data visualizations are not created by people trying to manipulate others. They are created by normal people who made small design mistakes. The data may be correct.   The conclusion may be wrong.  Because the visualization is wrong. Data visualization is not decoration. It’s decision-making. If a visualization is confusing, misleading, or hard to read, it is not a design problem ,it’s a communication problem. Over the years, a few fundamental principles have emerged from the work of people like Edward Tufte, Stephen Few, Alberto Cairo, and many others. If you follow these principles, your visualizations will already be better than most of what people see in reports, dashboards, and presentations every ...

Some words of wisdom

Image
While listening to podcasts, reading a book or scrolling through social media, some random quotes stick with you.  I've had the habit of writing down anything I feel I could use some day. I don’t really just keep quotes because they sound good. These aren’t from motivational posters or famous speeches. They’re lines I jotted down on a paper journal. Some are about discipline. Others about mindset. All are worth revisiting when you’re stuck or going through the motions. The 11 Words of Wisdom That Stayed With Me Trees don’t hang around with grass, even though they all started in the same place. Spend so much time on self-improvement that you have no time to criticize others. The magic you are looking for is in the work you are avoiding. If you are a friend for everybody, you are an enemy to yourself. If you always do what you've always done, you'll always get what you've always got. If you're going to try, go all the way. Otherwise, don't even start. Greatness do...

Prompts I use to 10x my productivity and time 5 Advanced LLM Prompts To Make Life Easier Why These Prompts Are Actually Useful Not being able to find time to share stuff is a hugle buttleneck. So I wanted to do a quick blogpost where I just paste my favorite examples of LLM prompts I used (and still use) to boost productivity and gain a little bit of time here and there. You’ve seen lists of AI prompts before, on blogs, websites, Tiktok videos... EVERYWHERE! Most of them are generic and are generated by LLMs. I built these prompts to work out of the box. They’re tested across models like GPT, Claude, Gemini, and even open-source ones. Each prompt forces the AI to output structured results — tables, summaries, plans — not just paragraphs of text. If you organize stuff, plan trips, read a lot, or manage projects, this is could be useful . Using smart prompts can save hours every week. What Makes These Prompts Better Most ...

Tech minimalism with TinyCore

 Hola! I've just written a very short piece about mindfulness. check it out to follow my train of thoughts, because this one is somehow an output of the how and the why to get to the what. Mindfulness is about being at peace, and one step closer to that peace is being able to accomplish things with the least amount of distractions. It seems that I'm starting to go "full on" at distractions these days... Don't mind me, I am in a long vacation, long enough to allow me to have some mindfulness and peace of mind to write these blogposts. We are drowning in technology in all aspects of our lives, especially when we spend the day at work, setting in front of a screen, batteling apps, tools and... distractions from notifications, emails, instant chat, system warnings, updates...etc Odysseus and the Sirens, Roman mosaic, second century AD. Bardo National Museum, Tunis In this spirit, I wanted to share something interesting, it's TinyCore ! I consider it a true tech g...

Why Consulting Firms Can Harm Business Growth | An Honest Take Before reading this, go ahead and read the below reference articles I listed at the end. So to apply myself to the previous post's mission statement (aka: write more often, about any topic of personal interest...etc.) I have some time on my hand here and I had a subject I long wanted to vent about. If you didn't know, I have spent a good portion of my professional life working for consulting companies. Overall it was 2 distinct companies operating in 2 different continents/countries. Pythagoras Emerging from the Underworld', oil on canvas painting by Salvator Rosa In-between, I have lived on the other side of the service contract, aka being the client. With this combined perspective, I have developed somehow a personal view on the value of consulting as a service, and as an economic agent, with a certain level of expected contribution to economic growth and developmen...

A year's worth of reflexion

Image
Writing on this blog has consistently served as a means to regain focus, delve deeply into intriguing topics, and hone the organization of my thoughts and ideas. Over the years, I've taken several breaks from blogging to concentrate on personal development, acquire new knowledge, and, more recently, dedicate all my time to focus on new professional endeavors. On a few occasions, I have included in my posts brief mentions of current pursuits that pertain to my professional life. Some were links to courses I was teaching, while others addressed less technical and more business-oriented topics. My most recent post was published a year and four months ago. In the meantime, I have accumulated around 14 drafts that never reached completion. Some topics proved to be rabbit holes, requiring extensive research to produce a worthy post. Others were merely distractions that I ultimately set aside. Over the past 16 months, I have reflected on the necessity, value, and purpose of writing on the...

  Open Banking 101: from a costumer’s perspective Following the first part of this article series about Open Banking, this second part is built a little bit different. We have seen in the previous part a straightforward definition of the concept of Open Banking, the regulatory background and it’s expansion and development throughout the world. I’ve wanted for the second part to focus on the advantages of Open Banking from a customer’s perspective.  It’s true that most of the public content online about Open Banking generally discusses this innovation from a bank or a fintech point of view, and usually it doesn’t present any arguments or explanation for the average person who will come across an account aggregation request without necessarily knowing what is that. So why would an “average joe” accept to share personal banking information with a third-party company? Below are 4 major advantages to switch to an Open Banking costumer experience. Enjoy the illustrations ! So what’...
