Spelunk v2.0.0 - The Multi-Module & Lean-Dependencies Release

Fri, 29 May 2026 17:00:00 +0000

I just released Spelunk v2.0.0, a major architectural redesign of the library to dig up secrets from various sources, for Golang.

If you have read previous posts about Spelunk, you know that the project started with a simple mission: to provide a single, clean, URI-based interface (scheme://location?modifier=arg) to fetch secrets across any storage backend—whether it is local files, environment variables, Kubernetes, HashiCorp Vault, AWS, Azure, or GCP.

With v2.0.0, I have re-designed Spelunk to solve dependency bloat and make the core library exceptionally lean.

Spelunk v1.2.0 + v1.3.0: Secret Managers and Extractors

Tue, 17 Mar 2026 12:00:00 +0000

If you read my previous post introducing Spelunk, you already know: fetching secret from any source should be easy, especially for your users. Reading them from HashiCorp Vault, Kubernetes or whatever should be easy to. If they where JSON objects, extracting specific fields should be easy. Switching between a secret providers should (repeat with me!) easy!

Well, since the initial announcement, my pickaxe has been swinging non-stop in the Spelunk caves, and I unearthed two updates: v1.2.0 and v1.3.0! 🎉

Digging-up Secrets? You need Spelunk!

If your Team, Organization or Company is serious about where to keep credentials used by services (or to interact with them), they are likely in Kubernetes Secrets, Hashicorp Vault, one of the various cloud-based Secrets Managers, 1Password, etc. Then, when running locally, they might be in your Environment Variables, in a .env, in a file or just in plaintext in a script (naughty!).

This might lead to services and tools written to deal with those different “secret provision scenarios”. Or tricky/brittle local setups.

Announcing Ksunami v0.1.x

Wed, 14 Dec 2022 00:00:00 +0000

October this year, while I was in the process of changing job, I started working on an open source project to monitor Kafka consumer lag. At New Relic, a previous gig, we used a lot of Kafka, and we cared equally about monitoring its usage: there are some great articles on New Relic own blogs, published over the years.

In the process, I realised that I needed a way to spin up a Kafka cluster for development, and I needed a producer of Kafka records, that was able to behave in accordance to specific scenarios.

TFZK - A Terraform Provider for Apache ZooKeeper

Fri, 02 Dec 2022 00:00:00 +0000

Gimme the TL;DR

A new Terraform provider is available, designed to interact with ZooKeeper ZNodes: TFZK. The latest stable version is v1.0.3, and you should give it a go.

Ah! And here is the doc.

OK, I got more time - go ahead!

Earlier this year I decided to scratch a long-standing itch: build a Terraform Provider for Apache ZooKeeper. While there was already one, it came with limitations that created issues in production environments:

Thinking out aloud: a JavaScript based console?

In the last month or two I started contributing to PhantomJS:

PhantomJS logo

PhantomJS is a headless WebKit with JavaScript API. It has fast and native support for various web standards: DOM handling, CSS selector, JSON, Canvas, and SVG. PhantomJS is an optimal solution for headless testing of web-based applications, site scraping, pages capture, SVG renderer, PDF converter and many other use cases.

The project is really interesting and we are seeing a steady growth in terms of:

Google Chrome: Is it the next generation of Browsers?

Tue, 02 Sep 2008 11:28:58 +0000

I don’t have an answer to this, it’s too early (we don’t even have a screenshot of it). But I strongly suggest to take a look a the Google Chrome Comic Book: a very new, fresh, funny and precise (!!!) way to introduce an incoming software.

They discuss a lot of different topics:

* Problems they wanted to solve

* Performance

* Process Isolation

* Javascript VM and Performance

* Sandboxing

* Phishing and Malware

* UI principles

Very interesting. And, again, very innovative.

Ah, the Rendering Engine they chosen is… WebKit (what a surprise!!! ;-) ) and… it’s fully open source.

An early leaked screenshot follows.

Google AppEngine resources

Sat, 30 Aug 2008 11:31:52 +0000

In the last period I’m spending some time working with Google AppEngine: if you don’t know what is it, be ashamed! :P

I would like to highlight a couple of interesting resources that can make the life of who works with this framework/hosting platform/cloud computing system easier:

* [Google AppEngine Cookbook](http://appengine-cookbook.appspot.com/) with a lot of good recipe (there are few now, written by the Googlers, but I'm sure it's gona blow up soon)

The App Gallery, with a lot of interesting applications already in production phase
