Sales Psychology, BERT testing, EVPN asymmetric/symmetric, git sync fork

Sales Psychology: I have noticed with myself lately, since I subscribed to a youtube channel, everything is a “negativity bias”. I can’t see any video with a positive message. I subscribed because I want to learn and improve but the publicity is wrong.

BERT Testing: I wonder if there is anything opensource.

Git sync fork. This something I have never tried before

1- Add remote

0) check your remote
git remote -v
1) Add new remote
git remote add upstream URL
2) git fetch/pull from the upstream
git pull upstream

EVPN VXLAN Asymmetric/Symmetric routing: blog1

Asymmetric IRB
– Ingress VTEP does both L2 and L3 lookup
– Egress VTEP does L2 lookup only
– Bridge – Route – Bridge
– Pros: “easy” to configure – just copy/paste. Identical config with the only difference in SVI IP addresses.
– Cons: on the way back, traffic will be reversed => all VXLANs need to be configured on all VTEPs => increased ARP cache and CAM table sizes and control plane scaling issue => not very efficient.

Symmetric IRB
– Ingress VTEP does both L2 and L3 lookup
– Egress VTEp does both L3 and L2 lookup
– Bridge – Route – Route – Bridge
– L3 VNI should be configured on all VTEPS, L2 VNIs only where local ports exist

Life, Love, Sex, Negative Beliefs, startup regrets, nanog90, Groq LPU, LLM from scratch, ssh3, eBFP BGP, RPKI, TIANHE-3

I hit rock bottom this week. I hope I finally closed one door in my life so I give myself the chance to open others. Made the wrong decision? It is easy when you look back. Do I regret it? The most annoying thing is these are failures so you can’t go back and recover. But I was so bloody newbie!!!…. At least after 5 years…

Head down, crying, cursing, whatever, but forwards. As it has always been.

Somehow managed to list to long videos, something I normally can’t manage (because lack of time, etc)

Negative Beliefs, avoid bitterness, aim for greatness (remarkable things), scape the darkness: Jordan B Peterson with Modern Wisdom: video, podcast.

Find and keep Love: video. 1st Get your shit together. Communication is critical. Be careful with your shopping list….

Good Sex: video. Communicate….

Orgasm: video. Haven’t seen it completely yet but very interesting. Use your tongue wisely.

— Other things:

Startup decisions and regrets: page. Interesting. I think most of things are very specific but still good to read.

Nanog90: agenda I didnt want the videos but I reviewed several pdfs and these ones look interesting:

Abstract Ponderings: A ten-year retrospective. Rob Shakir – Google: video

https://rob.sh/post/reimagining-network-devices/
https://rob.sh/post/coaching/
https://cdn.rob.sh/files/the-next-spring-forward_2018.pdf
https://research.google/research-areas/networking/

AI Data Center networks – Juniper – video

Using gNOI capabilities to simplify software upgrade use case: video – I had to idea about gNOI so looks interesting. It is crazy that still in XXI, automating a network device is so painful. Thanks to all vendors to make your life miserable.

Go lang for network engineers: video – I always thought that Golang had a massive potential for network automation but there was always lack of support and python is the king. So nice to see that Arista has things to offer.

PTP in Meta: video and blog.

There are more things, but havent had the chance to review them.

—-

It looks there is new chatbot that is not using the standard NVIDIA GPU. Groq uses LPU (Language Processing Unit). And they say it is better than a GPU. They have this paper but I can’t really see feature of that LPU.

Slurp’it: Show this blog, and the product looks interesting but although is free, it is not opensource and at the end of they you dont want a new vendor-lockin

Container lab in kubernetes: Clabernetes. I would like to play with this one day.

NetDev0x17: videos and sessions. link This is quite low details and most of the time beyond my knowledge. Again, something to take a look at some point.

LLM from scratch: repo. Looks very interesting. But the book it is going to take a long time to hit the market.

ssh3: repo. Interesting experiment.

eBFP and BGP: blog. Really interesting. Another thing that always wanted to play with.

Orange RPKI: old news but still interesting to see how much damaged can cause RPKI in the wrong hands…

China TIANHE-3 Supercomputer: Very interesting. Link.

Mindset Doctor – Inner Strength – Stretching – LLM in your laptor

Mindset Doctor: I struggle watching long videos in youtube (lack of time, many things to do, excuse(x)). I liked he used the concepts of chimp/human/computer brains (that reminded me again to this book) And how clear he was saying you need to befriend your chimp, anxiety is natural!, you need your chimp to vent, etc etc.

Inner Strength: This is a different world of endurance and mental strength. I need to read the second book of David Goggins.

Gut health: Interesting, we need more fiber.

And I need to improve my stretching (another), mainly because running.

You can run a LLM in your laptop. I need to try to play with this things.

Meetings Breaks – Google Lens – Milgran Questions

Just take a break between meetings: link

Google Lens: I bought a plant last weekend and I dont know the type… so no idea how to look after it. GL can help you to identify photos. I was quite surprised (as google search is underperforming for some time…) This is my new plant, spineless yucca. Let’s see how long it survives me.

Milgran Questions: via 3MM. And anecdote about Churchill, interesting.

When punishment for what people say becomes widespread, people stop saying what they really think and instead say whatever is needed to thrive in the social environment.

Thus, limits on speech become limits on sincerity.

TCP Port States – AI views – Prompt Engineering – 40s crisis – Unstoppable Motivation – 8 steps – Prisoners Dilema – Postgresql upgrade downtime

  • Interesting read about linux networking at TCP port level. It shows you how complicated can be but still amazing to understand Linux kernel.

  • Some views about AI:
    • 1) link1: Cory Doctorow about bubbles and AI. Models that run on commodity hardware will survive. He uses a 2×2 grid based on value (how much you will pay) and risk tolerance (how perfect the product needs to be)
    • 2) link2: Bill Gates views for AI. It is the word for 2023. And future for 2024. Still I think in link1, AI has to be democratic and easily available. I doubt most developing countries can afford NVDIA H200 in Azure…. I agree nuclear (fusion) energy is the only way forwards in the Western world until we have viable fision energy.
    • 3) link3: Prompt Engineering

  • Unstoppable motivation: This is an unexpected pearl. Intrinsic motivation is always preferred (more effective and energized) than extrinsic motivation (external elements: money, prizes, people opinion). But not always is so clearly binary. Extrinsic motivations can help too:
    • “Introjected Motivation. “I’m doing this because I’ll feel guilty or bad about myself if I don’t.” People who highly rated this statement have high introjected motivation.”
    • “Identified Motivation. “I’m doing this because I truly value the goal it’s helping me work towards.” People who highly rated this statement have high identified motivation.
  • Because having intrinsic and extrinsic will give you more tools to move forwards when one of them weakens.
  • “the only type of extrinsic motivation that corresponded with greater happiness was identified motivation. In other words, it was the hikers who motivated themselves by aligning their actions with what they truly valued and who not only completed the trail—but also felt happiest at the end of it
  • And the most important part of the article: How to get more intrinsic and identified motivation in your life:
    • Figure out what really matters to you: For me this is the most complex and scary part.
      • Long Term: The eulogy method
        • Medium Term: How will be your life in 5 years time if you follow Current path, alternative path and radical path? money, social obligations, and what people would think, are irrelevant. No excuses
        • Short Term: Wheel of life: measure your health, work and relationship.
    • Definitely I need to do the medium and short term. That would clarify many things…
  • 8 steps: i have read about rules but this keeps some basic into perspective:
    • Take care of yourself: shower, dress, etc
    • Order your room, kitchen, etc: your kingdom = yourself
    • Go outside – socialize
    • Sweat: work out
    • Money: control your economy.
    • Remove dependencies: sugar, diet attention (emails, youtube)
    • Strategy – create your action plan.
    • Execute: dont overthink
  • 40s crisis: I think we “overestimate” our cultural background, we think our lives are going the same phases as our grandparents or later. Quite wrong. This is a new phase and “recent” (half XX century). We are at the peak and we only see ahead the downwards of life. Likely our grandparents were already at 40. We have the social life cycle. That creates age-anxiety if we dont meet that cycle. Divorce increases along the years in XX century to reorient live. Min 31:25 is a pearl: We dont begin to live until we begin to die. And the real American dream (not based on materialism / radical capitalism) and moving to happiness in a hurry (consuming) created that crisis because you couldn’t achieve that American dream.
  • Application of Game Theory: Prisioners Dilema: Simplest win, tit for tat:
    • – nice (vs nasty): you dont defect first
    • – forgiving: you can retaliate but forgives
    • – retaliatory: strike back immediately, dont be a push over.
    • – clear: eye for eye
  • Interesting is that a small cluster of tip for taps can take over a population of nasty strategies. Most life is not zero-sum, try to find win-win.
  • PostgreSQL upgrade without downtime: Slides are ok, but would be nice to get the video for more details.

Git merge vs rebase, diff, patch, stash

This week I have had a bit of a struggle with git when trying to develop a change and I was getting constant conflicts when trying to get my branch up to date with main.

https://www.atlassian.com/git/tutorials/merging-vs-rebasing: A refresh for merge vs rebase. When I first started with git, the environment was pro rebase. But after that job, all places were pro merge. Somehow I visualize better a rebase. I will start using rebase to see if I really understand.

https://www.freecodecamp.org/news/git-diff-and-patch/: That’s how I finally managed to push my change into master. I had a diff generated by my gitlab PR and applied it into master.

https://opensource.com/article/21/4/git-stash: Something I already commented about but hardly used.

https://opensource.com/article/21/3/git-cherry-pick: Never used it but I was reading about this week as I thought was my only way out from the merge conflict nightmare I was in.
