Eduardo Zepeda's latests posts

I’m sure you already know this one, as it’s the most common, and probably the most popular captcha out there. Google’s and Cloudflare’s stand out here.

A few years ago, I migrated my website a couple of times, first from Wordpress to Frontity (A wordpress framework in React) and then from Frontity to a Digital Ocean Hugo App . I don’t regret my decision at all, but I made a few technical SEO mistakes that you can probably avoid if you take into account what I’m about to tell you.

After that incident I wrote

Why should I care about SEO if I’m a web developer?

SEO is the factor that determines whether a website appears first in the search results of a search engine (almost always Google) or whether it is buried in the last positions, receiving little or no traffic and condemning the business it represents to bankruptcy, or if it is a personal project, to oblivion.

Since ChatGPT rapidly surpassed the record of user growth, artificial intelligence is almost omnipresent in the modern metropolis collectivity. Its arrival has brought a wide gradient of expectations ranging from simple problem solving to the complete automation of our societies. But I think it’s overhyped.

But I believe that, while AI has amazing capabilities, it is far from revolutionizing the world and achieving the full automation expected by the general public in the short term. AI is awesome, but it’s overhyped.

This post is for you, who want to become independent from companies and are looking to create your own projects in the internet world. Have you ever thought if those extra milliseconds of performance that we get by switching a project to a more verbose language really matter that much or if the search for the fastest framework is really worth it?

In the world of programmers there is an obsession with speed and performance; we want to squeeze every possible millisecond out of the language and reduce memory consumption to the minimum possible and write queries in their most elegant version that pushes our database to its speed limit and and subject them to the most rigorous Big O performance analysis .

Working with Javascript is frustrating and, sometimes, combining it with HTML can be desperate due to its lack of internal coherence. On top of that, using it to handle dates, which requires considering the handling of timezones, different ways to represent them and the required sensitivity: seconds, minutes, milliseconds, etc. makes it a torture.

Javascript handles dates in a strange way

Javascript uses months starting from index 0 and days from index 1, two objects with the same date are unequal when compared with === (yes, I know that what is being compared are the objects and not the dates), but it is just the fact that it is not intuitive, the language user is not interested in the objects in memory itself, but what they represent.

Today this unholy news became popular, that an “AI Software Engineer” with the name Devin, made by Cognition Labs , will be available on the market. And, of course, it provoked a strong reaction among the software professional community. Reactions ranging from cynicism to fear to disappointment abound in the comments on the related videos.

While we are still far from having a self-aware AI , what we do have nice fine-tuneable LLM with promising features that threaten to turn the technology industry upside down.

It is no secret that these days software, in general, is trending towards a SAAS business model. However if you were there when the holy scriptures of the internet were written, you will know that this trend is rather recent.

OTS and software as a physical product

When the internet first came into use, it was common practice to sell software as if it were a regular supermarket product; you made a one-time payment and the product was yours, you owned it outright and you were free to use it until the inevitable collapse of our modern society.

The uses of artificial intelligence go beyond solving coding problems , and regardless of whether this artificial intelligence is conscious or not , it has endless applications. One of the most interesting applications for artificial intelligence is the development of new drugs. Bringing a new drug to market is an arduous, costly and, in most cases, unsuccessful process. Artificial intelligence can speed up the process enormously and narrow down the new drug candidates to a few, rather than dozens of them.

Composition over inheritance is a recurring theme in object-oriented programming (OOP). Usually, it is explained in a very complex way, but today I will try to simplify so even a child can understand it, purists will hate me but I’m willing to pay the price.

Let’s start our composition over inheritance explanation. Imagine you have a giant box of LEGO bricks, yes, those little plastic blocks that cause unimaginable pain when you step on them. But, in this case, we won’t use them to cause pain but to build different types of cars.
