BGP ORR: Things I am forgetting. At least people is asking about it.

Hyperscaler + Nuclear Energy: It is coming.

Summary 2025 OCP by Sharada: Power moving from AC to DC, liquid cooling is a must, NVIDIA netwoking in DCI with Spectrum-XGS (although I dont really see the details)

Global Scale-Computing: This is a new paradigm from current Hyperscalers design, they have the global scale but at the end of the day the compute is not just a global unit.

Cloudflare CPU perfomance benchmarks

Two kind of happiness:

1. Hedonic happiness
(Pleasure, comfort, distraction.)

2. Eudaimonic happiness
(Fulfillment. Purpose. Knowing your time here actually mattered.)

Hedonic happiness is cheap. It fades the second the buzz wears off.

But eudaimonic happiness endures. Yeah, it’s harder. It demands sacrifice. But it’s the only kind of happiness that leaves you whole.

Nokia Telemetry: I wish I could do that, so easily

Great Firewall of China Leak: info – I guess I will banned from China now. Honestly I would like to see more technical details.

Dojo shutdown: Sad

NVIDIA co-packaged optics: The video clip is so clean and silence

Videos:

DOAC McConaughey: It was like when I read his book. It is so appealing, raw, real: Resistance + Innate ability + Endurance

Almeyda: Confundes disfruta con ganar dinero / Dejar el dinero e ir a trabajar al campo con vacas y caballos.

DOAC + 1st Dr K: Very interesting anecdote, I remember that video and it was actually great. And I read DOAC book, and I was surprised that he actually uses the guidelines of the book: sweat the small stuff (long-term game), the last impression matters (peak-end rule), CO2 levels

I think these are the 3 interviews so far from Dr K in DOAC: 1st, 2nd, 3rd

DOAC + Vinh Giang: FORD: Family, Occupation, Recreation, Dreams — I think I can remember this word for the day I have a conversation….

Buffet and 300M in cash:

School of Hard Knocks: 15 pieces of advice

15: Dont listen to people who haven’t done the thing

14: If you dont know anybody, you need to become the person they want to know. You get a network, when you provide value. Build your own brand

13: Wealthy people get their money to work

12: stay small enough, long enough, you will be big enough, soon enough: keep the expenses low

11: Play 10y game – compound is a edge.

10: Master sales and marketing. Be everywhere, everytime.

9: Happy but not content: If you become comfortable in the top, the underdog will eat you.

8: Hire smart people and know your are not that smart.

7: Find a way to make money while you are sleep, if not your work until you die (close to 13) Money made with your brain, will outlast the money made with your back.

6: CEO = Change equals Opportunity

5: Marketing: everybody needs you, but they dont know who you are

4: Procrastination is the assesination of all destinations. What you can do today, dont do it tomorrow. Action takers.

3: Think bigger, same stress about 1000$ problem as the 100m$ problem, but at 100m$ bar, you have less competition.

2: Believe on your self: Does the bird on a branch, trust the branch or its wings?

1: Thanks God, I’ve got today. Tomorrow is not guaranteed. Live like you are dreaming

The 48 Laws of Power

This was a book that wanted to read for some time as Robert Green is mentioned a lot by Ryan Holiday.

I haven’t read “The Prince” from Machiavelli but one of the most interesting things I found in the book is the several references to Baltasar Gracian. So I have a new author to read about.

This is not a book about how to be a good person, it is about characteristics you need to achieve power. I am not an expert but I think many points are valid. If they are ethical, it is a different topic.

My favourites:

Always say less than necessary, reputation, win through actions not arguments, avoid the unhappy, crush your enemy, unpredictability, isolation is dangerous, Disdain things you cannot have and free lunch, aim to the head, seem effortless, not look perfect, learn when to stop.

Leviathan Wakes

This was a recommendation from a very good friend that was sitting in my kindle for a while. I dont normally read Sci-Fi. Apart from Foundation, Dune and Three body problem. And honestly I liked the book. It was engaging, you wanted to know how things were going to finish, and I really like the end twist, the different personalities, etc.

And with all the new rocket companies trying to reach the moon, mars, etc. Maybe we will have a situation like the book in the long future: Earth, Mars and the Belt.

I will read the next book.

Seven Brief Lessons on Physics

I bought this ebook as an offer and I was surprised about how short it was. It is easy to digest as it is not a hardcore science book

The most interesting lesson was the last one about “Probability, time and heat”. “the difference between past and future only exists when there is heat”. And the reason the heats from from hotter to cooler things is just probability…

And I dont mean I fully understood everything but It was a nice and light read.

A Path Through the Jungle

I bought this ebook after watching this video.

It is quite dense and practical. The author cuts most of the technical terms and make it easy to understand. It is a about psychology and the split between Human/Rational brain and Chimp/Emotional brain. It reminds me again to this book. Although he adds the concept of the computer too inside our brain. The Chimp is the strongest so you need to learn to tame it and live with it, you can force the chimp as he always beat the rational side. The computer is the fastest answering and it is used by the chimp so you need to have a good programming on it: your live values.

So the whole book runs around those three concepts so you can build a balance between them and live a stable life.

I liked it as I felt resonated with several concepts. I think they match a lot with Stoicism in the sense to accept the world, create your values and take action.

Azores

This year I travelled to the Azores Islands. Somehow I was a bit apathetic, I wasn’t in the mood of a big trip, not sure.

I followed this blog to make my planning. And didn’t check much as I wanted to go a bit with the flow. My main goal was to see whales (because swimming was not possible), trekking and see the sea. I visited Sao Miguel, Faial, Pico and Sao Jorge.

Although I made a couple of blunders in my planning (expired credit card, booked flights for something that I could take a ferry), it turned very good. I liked a lot, I trekked in the morning, and then I chilled in the natural pools in the afternoon. It was simple. I like the bread with corn flour: tasty, moist, fluffy, I need to try. As well, I tried the local banana and pineapple, and they were great! I dont like to go to restaurants alone so I mainly bought food in supermarkets.

I used this page for all treks, being the one linked the hardest one I did (go and back)

I didnt socialise much apart from one hostel that was really focus on that. But it was good to think on myself and refresh/recharge.

Netdev 0x19, RouteViews, Unexpected in Quantum Computing, BGP Bug, Scale-up fabrics, Network Engineer at Hyperscalers, CUDA in RISC-V, Tomahawk6, videos

NetDev 0x19: I would like to attend this one day, although is quite beyond my knowledge.

RouteViews Looking glass: link

Unexpected in Quantum Computing: A bit of a summary of the current state of quantum computing. In short, still quite to go (it seems you need 20 million qubits to break RSA-2048)

BGP Bug: link

Scale-up fabrics:

Network Engineer at Hyperscalers: Agree, but it shouldn’t just be for hyperscalers.

CUDA in RISC-V: good news, I hope it is developed, and RISC-V grows

Tomahawk6: A bit more visual

Videos:

Dr K: Masturbation – I really like this guy.

Janja Garnbret: just insane.

Jordan B Peterson + Michael Saylor: It is not about crypto, more about the life and path of Michael.

Veritasium: Quantum Mechanics – All paths possible: Very interesting video, ant the experiment is really nice

Veritasium: Electricity doesnt flow via the wires: I watched some time ago, and I wanted to recorded it here and try to watch again.

Humble Pi

It a funny book about about math errors in real life. An many of those errors are not isolated, they are like several slices of melted Swiss Cheese that are aligned and then is when shit happens as at some point there is line that can cross all holes. The important thing is to learn from mistakes, that are rarely published and make systems more robust (and i would say “simpler”) The errors in the books go from falling bridges, blow up space aircrafts, nearly missed fly accidents, medicines, etc.

Another things, correlation is not causality.

Nudge (Final Edition)

Interesting book for “Choice” architects. A nudge is any aspect of the choice architecture that alters people’s behaviour in a predictable way without forbidding any options or significantly changing their economic incentives. The intervention must be easy and cheap to avoid. A sludge, is the contrary, things that make your the choice process hard: ie, cancel your broadband subscription, etc

I think the main term in the book is the “Choice” Architect, and anybody that builds anything is one. An the main take of the book is, if you want people to do something, “make it easy”. This goes from buying healthy food in a supermarket, cafeteria, taxes, retirement investment, organ donations, etc etc.

The authors talk about “Libertarian Paternalism”, is like the economic concept of “Libertarian” but with a nudge, “Paternalism” so a tiny hand pushing you via the correct path.

Hardware Lottery, Tomahawk, FAANG, FlightAwre, Cloudflare Radar, GPU facts, Peter Shor, IBM, Seth Notes

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
