WebAssembly Agents: AI in the Browser Without Complications

Fri, 04 Jul 2025 12:00:00 +0200

Mozilla AI surprises again: AI agents that work just by opening an HTML

A few days ago I came across a Mozilla AI project that really caught my attention: WebAssembly Agents. And after 30 years watching the industry complicate life with dependencies, installations, and configurations, seeing something that works just by “opening an HTML” made me smile.

The problem it solves (and we all know it)

How many times have you tried to test an AI project and encountered this?

Moley: The Tool That Makes Cloudflare Tunnels Finally Usable (and Why We Needed It)

Thu, 03 Jul 2025 00:00:00 +0000

The Problem We All Have (But Solve Poorly)

As a DevOps Manager, I spend more time than I should configuring ways for the team to show their development work. Client demos, webhooks for testing, temporary APIs for integrations… we always need to expose localhost to the world.

Traditional options are a pain:

ngrok: Works, but ugly URLs, limits on free plan, and every restart generates a new URL
localtunnel: Unstable, URLs that expire, and often blocked by corporate firewalls
SSH tunneling: Requires your own servers, manual configuration, and networking knowledge
Manual Cloudflare Tunnels: Powerful but… God, the manual configuration is hellish

And then I discovered Moley.

Cloudflare Innovates Again: Cryptographic Authentication for Bots (The End of Fake User-Agents)

Wed, 02 Jul 2025 00:00:00 +0000

The Problem We All Know (But Pretend Doesn’t Exist)

As someone who has managed web infrastructure for decades, I’ve seen too many bots pretending to be what they’re not. User-Agent: “Mozilla/5.0 (Windows NT 10.0; Win64; x64)” when in reality it’s a Chinese scraper sucking up your content at 3 in the morning.

Traditional methods for identifying legitimate bots have been, let’s be honest, pathetic:

IP ranges: That change, are shared, or are spoofed
User-Agent headers: That anyone can forge in one line of code
Reverse DNS: That works until it doesn’t

Today Cloudflare announced that it’s integrating HTTP Message Signatures directly into its Verified Bots program. And after reading the technical details, I have to admit something: this could definitively change the rules of the game.

Why I'm Fascinated by Distributed Sorting (and Why You Should Be Too)

Tue, 01 Jul 2025 00:00:00 +0000

A Revelation in Algorithm Form

Thanks to an article from System Design Academy that came my way this week, I’ve been reflecting on something I find curious and simple at the same time: how to sort massive datasets in a distributed manner. And you know what? These patterns are so elegant that they can be applied to so many other problems we face day to day.

As a developer who has gone from JavaScript to PHP, then Python, and is now fully immersed in Golang, I’m struck by how certain patterns transcend languages and frameworks. Distributed sorting is one of those cases where architecture matters more than implementation.

Laravel Blueprint: The Tool That Revolutionizes Scaffolding with YAML and Saves You Hours of Development

Fri, 20 Jun 2025 00:00:00 +0000

How many times have you started a Laravel project manually creating models, controllers, migrations, factories, form requests, and tests one by one? If you’re like most Laravel developers, you’ve probably wasted countless hours on these repetitive tasks that, while necessary, don’t add direct value to your application’s business logic.

Laravel Blueprint is completely changing this paradigm. This code generation tool, created by Jason McCreary (the same genius behind Laravel Shift), allows you to generate multiple Laravel components from a single, readable, and expressive YAML file. In this deep analysis, we’ll explore how Blueprint can transform your development workflow and why it’s gaining traction in the Laravel community.

CookieStore API: The Async Future of Cookie Management in JavaScript

Thu, 15 May 2025 00:00:00 +0000

For decades, web developers have depended on the old and limited document.cookie interface to handle cookies in the browser. This synchronous API, with its peculiar string syntax, has been a source of frustration and errors. But that’s changing with the arrival of CookieStore API, a modern and asynchronous interface that promises to revolutionize how we interact with cookies.

The Problem with document.cookie

Before diving into CookieStore, let’s recall the headaches document.cookie has caused us:

Sharing Code Between Applications Using Yarn Symlinks: A Simple Alternative to Complex Monorepos

Mon, 15 Jul 2024 00:00:00 +0000

Have you ever found yourself duplicating utilities, data types, or components across different applications? If you work on multiple projects that need to share common code, you’ve likely faced the dilemma of how to manage this shared code efficiently.

Recently, while exploring different approaches to share code between applications, I stumbled upon an elegant and simple solution that many developers overlook: Yarn symlinks. This technique might be the perfect answer if you’re looking for a lightweight alternative to complex monorepo setups.

One day I'll discover what the comfort zone is, or not

Sat, 06 Aug 2016 00:00:00 +0000

Moments of change, moments of evolution, a constant in my life, with the 25th anniversary of the creation of the web I’ve entered “review” mode and I’m highly perplexed.

I’ve been doing things for the same time (25 years), enjoying, always with the same concept and particularity: Enjoyment and result, but it hasn’t been relevant for a long time (which is also not very relevant).

I’ve realized that the usual thing is to do things within your comfort zone, and I’ve never had one or knew one could exist, hence I’ve touched and done unusual things or perhaps “untimely”, when a certain technology could be in fashion “Buzz” I hadn’t been using it for a long time because it didn’t give me what something else gave me,…

Laravel Collections: Arrays on steroids

Fri, 01 Jul 2016 00:00:00 +0000

Laravel, in addition to using multiple third-party packages, is also possible to use parts as components. All components are under the “Illuminate” namespace.

If there’s a really interesting and useful class, it’s Collection, which allows us to work with data arrays in a simple and “programmatic” way.

To have this class in our project, we only need the illuminate/support package which we can install with:

composer require illuminate/support:5.2.x-dev

To show some examples, we’ll use a small array with this data:

Recapitulating

Thu, 08 Oct 2015 00:00:00 +0000

I’ve started to see what I’ve been touching lately, and not surprisingly, it’s… simply “eccentric”, in the sum of elements but not in the use of each one.

Text Editor: Sublime Text, Atom I can’t get used to it (largely due to its complicated integration with Go and Gb), and the same applies to atom for PHPStorm. In the terminal, my header editor is Joe and this has an explanation: my first text editor was WordStar and I’m a nostalgic.

Thu, 02 Apr 2015 00:00:00 +0000

Every day we hear about Big Data, IoT, Smart Data, Machine Learning, semantic data, etc. Many times out of context or simply used because they’re “trendy”.

One of the best examples is “Big Data”, where we always talk about huge amounts of information, systems, platforms, queries, but with the error, from my point of view, of taking that as information, no, no it’s not information, they’re data, raw data or processed data, information is what is extracted from that data. Many times, with the term “Big Data”, we get lost in only the part of storing huge amounts of data, replicated and in astronomical volumes. That’s not “Big Data”, that’s only talking about one part, the most mechanical one, and the one that contributes least to what we’re looking for “Information”, it’s only “data storage and management”, one leg of a much broader table.

Development is more than just using "components"

Fri, 30 May 2014 00:00:00 +0000

One of the recurring conversations in gatherings over a beer is the current trend, by many “developers”, of not really programming to client needs but simply using modules/components/plugins/…

Excessive use of components for very simple needs

This causes the final solution to be nothing more than an amalgamation of elements, many of which were not designed for that function, and others that are really not necessary, that only create the sensation that everything is solved, but as an “AS IS” solution. The kind where you don’t touch them, because we don’t know if something might fail, nor how, nor why.

Custom Theme My Login templates

Thu, 23 Jan 2014 00:00:00 +0000

Theme My Login is a plugin that allows us to adapt all elements related to: Registration, Login, … of a WordPress site to our needs.

Inside the plugin folder, we find the templates in the “templates” folder. As is standard practice, we should not modify these templates directly. We can copy them to the root of our theme and modify them there. From that point on, those templates will be used by our site, without a plugin update affecting the changes made.
