No free lunch

Just a reminder

“Every single pursuit – no matter how wonderful and exciting and glamorous it may initially seem – comes with its own brand of shit sandwich, its own lousy side effects. Everything sucks some of the time. You just have to decide what sort of suckage you’re willing to deal with.
So the question is not so much ‘What are you passionate about?’
The question is ‘What are you passionate enough about that you can endure the most disagreeable aspects of the work?’
Because if you love something and want something enough – whatever it is – then you don’t really mind eating the shit sandwich that comes with it.”
- Mark Manson
In a world of comfort one question the most important question to ask yourself is what are you willing to struggle for? You can have the pain of being lazy or the pain of putting an effort into your health and body? Which one will it be?


I received this blog entry and I decided to try Ecosia. A friend commented about it some time a go but never decided to make a move. Sometimes thought to use DuckDuckGo, but let’s see how this goes.


I can agree that 2020 hasnt been the best year ever with all the issues happening: racial violence, USA political turmoil, coronavirus, etc. But I need to look at the bright side:

  • Got a job offer in Jan 2020 that opened doors to very interesting changes in my life.
  • Got a visa for a new country
  • Leave my old job
  • Stay out of work for two months, learning a lot “working” from home.
  • Start this blog
  • Reading more books than other years
  • Visit Sofia (Bulgaria), Porto, Nazaret and Batalla (Portugal)
  • Remind my Karate
  • Fitter than ever (no injuries, more days training)
  • Passed Kubernetes CKA
  • Cold showers + breathing routines
  • More scheduling than to-do list
  • Cooking many new things.
  • Saving a lot
  • Helping family
  • Friends are doing well.
  • Focus in my mental well-being
  • Start a new job


Very interesting link shared by a good friend. I wasn’t aware there was a bit of openness about the vaccine, taking into account that at the end, this is business….

I like the similarities between computing and DNA/RNA and the hacks introduced to make it work (plenty of Ψ, production enhancements, spikes, AAAs end) I think this should be interested to show in schools to get more students in science.

I didnt know the founder of PowerDNS was so keen of biology.


In one of the summaries I receive, I checked this article. I had read before about vertical farming and I thought it was a really interesting idea, mainly for the saving in water and soil. But I never thought that they were actually quite expensive to run because the electricity and tech needed (and real state). I am pretty sure that at some point not very far in the future they will be cost effective. Although it doesn’t feel natural.


Interesting read about the Post services and the cost structure they have been handling with the years. Sending an international letter, although not very often, looks like such a simple transaction. But it was interesting to realize that sending letters was initially a privilege and then became main stream and the only way of communication until not far ago (thanks internet with emails, etc etc). And then you had an international organization to deal with the mail exchange between countries. At the end, it is a comparison exercise between the cost of mail and the cost of using internet. Enjoyable read about history and related to the internet.

The Great Suspender

No, it is not me when I was a kid. It is a GC extension. I have a very bad habit of opening many tabs in my browser with the excuse, I will take a look later. That takes a big toll in CPU/Memory. With this extension, my laptop is running very smoothly even when I have three cEOS docker boxes running in the background. The fan runs less often. I have been using it for over a week and I am very happy with it. Need to find something for Firefox.


Today I Learned. Why are we bothering writing things in a blog?

It is a drop in the ocean called Internet but I believe in it. That is the key.

And somehow it can helps us to discover the signal from the noise

Maybe not totally related to this post, but I think you can find that book interesting.

Are we making noise?

History: URL and more

I had in my backlog a long post from Cloudflare about the history of URL. It actually contains much more info. So it is a really nice reading:

There are many things that I didnt know but these two caught my attention:

The root DNS zone of the internet is composed of thirteen DNS server clusters. There are only 13 server clusters, because that’s all we can fit in a single UDP packet. Historically, DNS has operated through UDP packets, meaning the response to a request can never be more than 512 bytes.

I knew there were 13 root DNS cluster but I didnt think the reason why was the UDP packet size!

And from Punycode, interesting you can create emoji urls!
