Complete Linkwitz Setup

This is a follow-up to my previous post on how did I came to this place, so an interested reader should head there first. After about a year of working on this on and off, I now have complete setup of the best work of Siegfried Linkwitz with a pair of LXMinis, a set of W-Frame subwoofer dipoles based also on his design, and the simply spectacular LX521.4 full range dipole speakers.

Turning 50 in Tech

It’s hard for me to believe but it’s been half a century of “me”… and as we humans go through our hardware lifecycles, it’s good to take a pause and think about what it all means at some stages in the road. Yes, it’s technically just another number. No more or less important than 14, 46 or 81. However, it has a soft meaning, a cultural significance, and its associated stereotypes.

Setting Up CJDNS on pfSense

CJDNS is an IPv6 encrypted mesh networking technology, used in Hyperborea and other mesh networks around the world. I particularly like the way it’s conceived, with end-to-end encryption, distributed IP address allocation, DHT-based source routing and MPLS-like label switching. It has several interesting use cases, but I wanted to set it up in my pfSense gateway VM so I can use it as a distributed VPN of sorts. This could be useful to be able to access my systems from anywhere while traveling, or where my team can share access to each other’s Cloud Foundry labs, particularly when we travel.

On Becoming a Gourmet Cook

I recently exchanged emails with a family member in Chile who was joking she couldn’t imagine me in the kitchen, when she learned from my mom that I’m a self-proclaimed “gourmet cook”. I guess it makes sense. When I left Chile almost 20 years ago, my kitchen skills were really minimal, in spite of having grown up in a household where my mom cooked daily, and where my grandma Nicoletta, with her Italian heritage, made the most delicious dishes every time we visited.

Selecting the Right VPN Service

I first published this in 2013 but since I’ve been asked recently by several friends, I figured I update it with more current information. For the record, I’m a CISSP, and as such, computer security is always in the top of my mind. For me, that also extends to privacy. Since I spend a good amount of time at airports, hotels, coffee shops and generally roaming around, having a VPN service has become a necessity for me as well as for anyone who values their online privacy and safety, even at home.
