Hardware Lottery: There is Cerebras, attempts of optical networking and interconnects. So I guess there is a bit of variety out there.

Tomahawk Ultra:

With the Tomahawk Ultra, Broadcom has a switch ASIC with 51.2 Tb/sec of aggregate bandwidth that runs the Ethernet protocol and delivers 250 nanosecond port-to-port hop latency and can push through 77 billion PPS. That is twice the PPS at the same small packet sizes common in HPC as the 102.4 Tb/sec Tomahawk 6 switch ASICs from Broadcom, which have a latency of somewhere between 600 nanoseconds and 700 nanoseconds for these packet sizes.

Network Engineer at FAANG: Need to read all posts

Arista UltraEthernet: Intro

FlightAware: Interesting for tracking Ryanair flights…

Cloudflare Radar: Need to test it

GPU facts: It goes beyond me very quickly but still interesting

Peter Shor Quantum Notes: For when I retired

IBM Quantum: In the last months, there have been many breakthroughs but I still dont see any real application. This is also quite beyond me so maybe I am missing the plot.

Seth Notes: Amen

The Happiness Hypothesis

Very interesting book, as per the title, it is about happiness and how to get there. There is a significant focus in Buddhism and Stoicism, as these philosophies started to look at this “problem” a long time a go and can help us to understand it. Both are focus in the individual and mainly in your interior. You only control your opinions and actions. You can’t control anything outside your skin, and if you try, you are doomed. Stoicism is something that really resonates with me and is giving me a lot of support.

The core of the book is the concept of the elephant and the rider inside your mind. We think the rider is in charge, but it is the elephant. The goal is how to guide the elephant for the correct path. The elephant is our “animal” past and it was been there for a long time so it requires a lot of touch to dominate it.

But the author says that not all happiness is in the individual. Human beings are social creatures so we that connection too as par of the happiness. And we need also espiritual happiness.

At the end, he says this is ying-yang and there is no perfect solution, it is just finding the balance.

To be honest, I think I have done a shitty summary of the book. It needs more credit.

Coquitos

I had some shredded coconut and decide to make something I wanted for some time, “coquitos”. I found this video and I was surprised how easy it was!

Ingredients

  • 80g sugar
  • 100g shredded coconut
  • 1 medium egg
  • 1 tbs vanilla essence

Process

  • Pre-heat oven at 180C
  • Mix sugar and coconut
  • Add egg and mix all very well. Use the hand at the end
  • Let it cool down for 30 minutes in the fridge
  • Make small gold balls with the hand and leave them in a tray with baking paper
  • Bake for 15 minutes or until golden

I made 9 coquitos:

They were tasty and lasted for a long time
