The Art of Memory

I finished this book and to be honest it has been a bit of a “tostón”. I read it because was referenced from another book (I dont remember which right now) and I thought it should be interested.

The book starts in the Greece of Socrates/Plato times. Socrates didnt write anything and all his lessons/learning were oral. All we know come from Plato. So all teaching from Socrates was based on Memory. And obviously you had to memorize a lot and techniques to do that should exist (and of course were not written). The idea was to find a building and create a history from its features. Kind of mnemotechnics. As well, we have Aristotle.

I have been always more keen to understand things than memorize but there are cases where you have to memorize and the rules has been always repetition and brute force. But in some few cases, I have learned to use mnemotechnics and I dont know why this technique is not taught more often. I will always remember EIGRP parameters (bad dog loves red meat – b d l r m – bandwidth delay load reliability mtu) and BGP best path decision process (NWILLA OMNI – I have in my mind the spanish footballer David Villa playing in Africa)

So until that point the books was good as a history refresh.

Then we moved to the Middle Ages with St Thomas Aquinas, St Albert Magnus as next figures in the art of memory using the old Greek master. I always remember St Thomas Aquinas as the person who converted Aristotle writings to Catholic views. And St Augustine, who converted Socrates/Plato to Catholic. So the Church in those times could cope with the new threat of people using their brains. Here things get messy in the book and start losing track. Things looks a bit esoteric, magical, the ocult.

And when we reach Ramon Llull, I feel quite lost. The book start talking about Cabala and some other things. I had some reference from RL before (it is the main university in Majorca and wrote in catalan) but nor much more.

Moving forwards to the Renaissance, I hit two figures totally unknown to me: Giulio Camillo and Giordano Bruno. The first one, built a theater for the King of France as an example of memorizing the universe. And Giordano write several books about the art of memory that look quite complex due to esotericism, occultism, magic and references to Egyptian religions, etct.

In the last part we reach the Shakespeare times and the architecture of the Globe theatre as example of art of memory. Big debate if it is a circle or hexagon originally.

And finally, Leibniz, that refers to Ramon Llull as one of his references to create a common language that turned up to be Calculus.

It is like all this occultism, turned up as just Mathematics. In other references to Newton, he tried to convert lead into gold, and tried a lot of crazy stuff. So it looks like it makes sense that the begining of the science we know today was pretty much connected to esotericism, hermetic, occultism, etc.

I checked the author, Frances Yates and it seem she focused on esotericism.

Anyway, I tried to take positive things, mainly historic. And I learned from “new historical figures”.

HiddenLifeOfTrees

I just finished this book about trees. It has been interesting to learn how trees communicate (roots), socialize and live (slowly). Trees has been in Earth before us so respect to them. And how much Nature doesnt need us. Maybe it is difficult to believe that trees feel, communicate, suffer etc. But they are living things like us. They have survived longer than us. So even if they dont have a conversation about Bach or Godel, they still do it their way, more “primitive”, maybe yes, but it works. So I learnt a lot in this book. Mainly the communication system via roots, the social support, defence systems, reproduction and how is better leave a forest on its own. An somehow, it came to my mind the Ents. Very likely my favourite part of LOTRs.

Looking forwards to go trekking soon!

GEB

Finally managed to finish GEB. I read it for first time when I was in university in Spanish. This time I wanted to read the original version. It is a dense book with topics I didnt grasp at that time. Now, I am a bit more up to date but still find it hard although still very interesting. The last part is quite focus in AI and you notice how far has gone this field in the last 20 years since this book was written. We have AI beating the best players in chess and Go. And even go further to work out 3D shape of proteins. So this goes well with another part of the book related to DNA and replication.

Still one of the main topics of the book it is Godel’s Theorem. It is the typical thing, I think I understand conceptually and then in a different topic, I lost it. Somehow, I want to connect Godel’s to software engineering in respected of bugs. In my head, the more complex the software, the more vulnerable becomes. But not sure how to explain it.

As well, the author has made some very good drawings to connect with the text. Quite original.

To be honest, the musical terms are quite puzzling because I dont understand most of the topics but I am trying to listen to the Musical Offering of JS Bach and try to find “something”.

I hope in another 20y, I can make more sense of it.

Mindset

This is the last book I read this week. I bought it after reading other book this Summer about focus. And to be honest, I was quite surprised. The main idea is if you believe your capabilities/skills are born with you or you can develop them. Dr Carol Dweck shows how is life when you think you can develop your skills. And that is useful for anything. As well, you can have a growing mindset for some things and a static mindset for others. My mindset for the book was that it was going to be all about career and hard work. But I was surprised that there were more subjects related to a growing mindset, like education (children), family and relationships. I was to narrow-minded initially to the idea of growing mindset but it makes sense to apply it for everything in life. Learn when you have static mindset and make the effort to grow. Drop by drop, the bucket gets filled, said my Golang instructor. I really liked the examples about teachers who went beyond anything to show their pupils they could learn, and they did. And reminded me to the Dangerous Minds movie. I have told myself millions times that some people are born smart and I am not. But I need to realize that I have been growing since I decided to study and advance in my life. So, keep applying it, keep growing. For study, for work, for sport and relationships…

Tao-Te-Ching

I finished this book this week. My favourite part was the introduction as it gives a brief view of China’s history and the thought schools developed around 100-500 BCE. One of the main figures of that time is Confucius and his school of Confucianism. Other school developed in that time was Taosim. It looks back to an ideal time even before the origins of the first Chinese kingdoms, all based in a basic way of life: survive with the minimum and avoid problems. There are a lot mysticism and no much logic in the statements, but it seems that’s the goal. Follow life, it is not lead by logic (as we would like).

Some of my favourites:

Knowing others is intelligent.

Knowing yourself is enlightment.

Conquering others takes force

Conquering yourself is true strenght

Knowing what is enough is wealth

Forging ahead shows inner resolve.

At the end, the book is small, but it can be tricky to understand. The philosophy is quite different from the Western one I am use to but I liked it. There are always small gems to take with you.

IronFit

I finished this book this week. I was interested how you can prepare for an IronMan or a normal triathlon. I like to have a training plan for different levels of commitment. And the planning for the race itself. I have learned some tips to improve in the three sports. At some point I would like to try a triathlon (I need to join a swim gym and get a heart meter). My only concern for a bigger challenge is the left knee. But, step by step.

Doctorow-Tor

I finished this book yesterday. This was my first book from Cory Doctorow, I have heard about him for some time about his support for digital freedom and his blogging (never read it though). Somehow I decided to read something from I chose this book as it seemed the latest. And to be honest, I am glad I did it because I liked it. I didnt know what to expect the four novellas really hit the nail on the head in the main issues of our society:

1- Immigration – Digital freedom – Social connection – Social classes – Youth against injustice

2- Racism – even superpowers can “fix” it – America blind eye (and the whole world to be honest)

3- Healthcare (cost, politics, etc), Brutal-capitalism, Radicalization, Guilt, Mental Health.

4- Clean water, Global instability, Violence, Social disconnection

I have the feeling that you can see the current work in each history. In one part you think we are doomed but there is always a spot of hope. And it is just “having hope”, it is taking action.

And I learned that the DMCA was signed by a Democrat…. good b-job Clinton…

And I want to use more often Tor more often. Just for browsing it is really easy.

WisdomOfInsecurity

I finished reading this book last night. To be honest, it has been hard to read and digest. Very hardcore philosophical for my level. To put things a bit on perspective, the book was written on 1954… and half way the book you realize that things he talks about are still pretty valid nowadays. Without noticing, he is taking a approach to Easter philosophy (Buddhism) in contrast to the Western one. We are very focus in the “I”, in the material world, etc. We try to get things defined as something static and we need that for security. Our brain is the one leading the shots but taking a different approach, accepting the insecurity (you can’t control everything, you can’t know everything) you can live a less stressful and meaningful life.

Again, this is the typical book I should read 30 times to get really a full understanding.

ADHD

Finished this week this book. ADHD is Attention Deficit Hyperactivity Disorder. I didnt know it was like your brain madurates more slowly than normal. of Something that is getting more diagnosed these days. Maybe we were like that when younger or even our parents still are. It quite interesting to see how strict is the society when you are not 100% fit for purpose. The education system is built for a common type of child even the interaction with others. If you are not one of that class, you are going to have a difficult time and the future is not going to be very bright neither. So quite challenging to be and live with ADHD. But there are ways to move forwards if you want. The author follows the 5 Cs to deal with this “challenge”:

  • self-Control: If you lose your temper…. breath, meditate, step back.
  • Compassion: Think how the person in the other side feels.
  • Collaboration: Get the other side involvement in the decision making process.
  • Consistency: The process is not just day. It is a long, slow process.
  • Celebration: Yeah, acknowledge the good things. So the other Cs get stronger.

At the end of the day, you are not stupid, you have a different path for madurity and other skills.

At the same time I was reading this book, one day in the radio was this program about dyslexia. It was socking to know that about 50% of USA inmates were dyslexic… And again, it seems the end of the world… but in the program was an interview to one director from GCHQ saying that he was dyslexic and they were hiring for them. Why? Because they see and approach things in a different way.

So, at the end of the day, whatever you have, you can still move forwards in life. You dont need to be in the “normal” range of population/people.

BGP-StockMarket-EGB

I was reading through my backlog and noticed too close by incidents. A BGP hijack on 30th September from Telstra and Tokyo Stock Exchange outage on 2nd Oct. At the end of the day, small mistakes/errors (on purpose or not) can cause massive impact (depending on your point of view). For BGP, RPKI is the security framework to make sure the advertised routes belong to the real owners. Yeah, quick summary. But at the end of the day, not all Internet providers are using RPKI, and even if you use it, you can make mistakes. This is better than nothing. For the exchanges, thinking that a piece of hardware can cause a stop to a 6 trillion $ market is crazy. And it seems is just a 350 servers system. That tells me that you dont need the biggest system to hold the biggest value and you will always hit a problem no matter how safe/resilience is your design/implementation/etc. Likely I am making this up and I need to review the book, but one of the conclusions I took from it, via Godel, it doesn’t matter how many statements you use to declare your (software) system, you can always find a weakness (false statement).
