The first year of the decade started with a return back to Berkeley from a two-week holiday trip to New York. Here are some things that I found memorable this month.
Henry’s Kitchen: Meatloaf for One
I used to watch these videos years ago. I was so happy to see Henry is still making them. Pure comedic gold.
Hack the Box by IppSec
The guy has a YouTube channel full of hacking videos. He is super slick with Bash, Linux, and an arsenal of hacking tools. I like his pacing in these videos. I find these videos to be a fun way to learn about security and how to be more effective in Linux and on the web.
The One You Feed: Pete Holmes on Discovering Spiritual Truths
I’ve been really into Pete Holmes the past couple of months. I read his book Comedy, Sex, Love, and could relate to his upbringing and path towards spirituality. He’s a funny guy, but I really love it when he talks about God, spirituality, and religion; which is what this episode was mostly about.
A Silver Mt Zion: 13 Angels Standing Guard ‘Round the Side of Your Bed
It’s hypnotic. It’s haunting. It takes me to a place beyond this world.
The authors of the tutorials for RabbitMQ deserve great praise. First off, the comparison of RabbitMQ to a post office really helped me grok what a message broker system is. A queue is a P.O. box. Producers put mail in the P.O. box. Consumers take the mail out of the box.
Not only are the tutorials well-written, but they are also encouraging for newbies. They don’t overwhelm you with too much information upfront, and they are broken up into chunks that build up from the chunk before it. And for a cherry on top, they offer these tutorials in a handful of languages so you can choose the one you are most comfortable with.
Tragedy struck this month with an unfortunate helicopter crash that took the life of Kobe, his daughter, and others.
kobe seemed like he was just getting started. no doubt he was one of the greatest athletes of all time, but he also seemed like a great father, mentor, and coach. he embodied greatness like none other. what an awful loss. may his spirit live on in anyone who was inspired by him.
I recently saw someone call a Kubernetes Service, “headless”. I have also heard this term in the context of the Chrome web browser running in “headless” mode. It’s a confusing term to me, so let’s explore it.
“Headless” means not having a head. But what is a “head” in these contexts?
Here is the Kubernetes Service that gmr called “headless”.
clusterIP: None # <--- This is what makes it headless
- name: http
- name: amqp
By setting spec.clusterIP to None, the Service is headless. It no longer acts as a load balancer. In a way, it’s like a lot of the overhead is removed and you are left with a stripped-down version of a Service.
A headless service is a service with a service IP but instead of load-balancing it will return the IPs of our associated. This allows us to reach each Pod directly, rather than the service acting as a load-balancer or proxy.
I’m starting to see that “headless” might just mean part of an application instead of the full version.
How about Headless Chrome?
Headless Chrome is a way to run the Chrome browser in a headless environment without the full browser UI. Headless Chrome gives you a real browser context without the memory overhead of running a full version of Chrome.
