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 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.

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.
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?
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!
This is nothing new. But I was reading an article about it and was a good refresh:
The article is a couple of years old but I think it is still relevant. Most people I know they have their infrastructure in the cloud. In my current job we are still based on bare metal due to the nature of our business but some years ago we were in that point when deciding what to do with our CI/CD environment. I wasnt involved in that decision (only in the deployment/implementation). Our capex was higher but long term (3y), it was cheaper to build in premise than in the cloud. I agree with the article that when you dont know how things are going to grow, scale requirements, etc cloud is the best choice. Once you ran pass the start-up phase, you should reconsider the position.
