Screencasts and videoplayer

For some time I wanted to record a video in my laptopp so I could watch it offline. I found OBS but looks too much for what I want and then vokoscreen came along. I used it, it is easy and does the job.

Then I realized that VLC stopped working (need to investigate why and try to fix)… so I need another videoplayer. Again, I want something simple, and tried Kodi, I thought I was a bit too much, but I didnt have to install too many packages and it worked. So for for now, I have a videoplayer, although I miss vlc.

Leaders Eat Last

I bought this ebook some months ago as a recommendation and then after watching a video (need to finish it) of the author, I went to the book.

The main source of examples in the book are the military where he shows the success is based on people believing and action in a bigger goal than themselve: the mission and your team mates.

As well, he put example of a few companies that have built a personality/culture where people feel identified and they survive the worst moments. And there are examples of the opposite, where companies like Goldman Sachs, GE, etc have a culture of immediate profit, individual success at any cost, that are negative in the long run.

He mentions dopamine and oxytocin as hormones impacting our behaviour. Dopamine is the quick/easy hit satisfaction (watching youtuvideos….) and oxytocin is the making you happy with social interactions. In our modern world, dopamine is not the choice and oxytocin should be the long term aim.

As well, he takes the AA as an example where people success if follow the rules, and the most important one is the last rule, to be a leader/mentor of another person.

One of the disconnections we have at work is the abstract challenge (we want to be number 1, we want to be the best, etc) that doesnt really resonate with most people and doesnt create any connection. Without that connection, that meaning, you dont fight. So that put in context in another part of the book, that most of the times, our best memories at work are moments of straggle (that tough project, that bug at 2am, etc). So you go through that if you have a connection with the company, culture and people (that releases oxytocin). If not, you will not last long there.

Another part talks about the destructive abundance. We live in a world where we have everything…. so we want it all. This part gives away some leadership leason:

1- So goes the culture, so goes the company

2- So goes the leader, so goes the culture

3- Integrity matters

4- Friends matters

5- lead the people, not the numbers.

In my personal view, at the end all looks very nice, but most of cases, it seems the solution or change needs to come from the top and can be overwhelming. But still we can “lead by example” in our small part. You can lose your job but you can’t lose your integrity.

Good book. Again, I should read it again and take notes.

Bakeries -p3

Second visit to KEIT: This time I tried “Weizenbrot” . Ingredients: Natural sourdough, red wheat, whole grain rye, wheat 550, water, thermal salt. Again, amazing bread!

Bäckerei Siebert: This is a very German bakery. There was a queue when I got there and it was going to close soon I think. I bought some pieces of cake and a small black brot. Maybe arriving earlier I could have seen a better selection of bread. My german is still pretty bad so I kind off pointed to the things I wanted to try without being too sure. One was carrot cake, other cherry cake, and the other not sure. They were tasty anyway.

Bäckerei Kädtler: via link. This is a kosher bakery. I got a bit late as is far from home, and it was nearly empty! So I only tried three biscuits. They were nice (nothing crazy) and not very sweet so I liked that. So need to get there first thing in the morning to really taste the good stuff.

Hacker Bäckerei: This was a visit just by chance after trying Kadtler (above). I was in the area, checked google maps, the pictures looked nice, went for it. It was a blast! I didn’t try any bread, nothing caught my eye but I tried two “cakes”: Splitterbrötchen (slivered rolls ) and Apfelsandkuchen (sand apple cake). The first one is like a slightly sweet/soft bread. And the second was a big piece of cake! and tasty! Really happy with the discovery. Later I checked in the internet about the place and has interesting reviews. link1 and link2. This a proper East Berlin bakery. I need to come back earlier and try other cakes and bread (sourdough). As I got pretty late the backerei was pretty low in product. It closes at 12:30 I think so that is a signal that is a very local shop 🙂 So next time I need to get there first thing in the morning.

Four Thousand Weeks

That’s the amount of weeks you have if you live approximately 77-78 years. And this book is about time management those weeks. It is not the typical book about techniques to make more in the same amount of time but the psychological and philosophical reasons why we want to make more and how to live with that.

We live in a world where everything, even time is a commodity and you want to squeeze the last drop of it. That goes deep into our society. The author has tried all possible techniques to be super productive but at the end, he is always defeated at some point.

So you have a limited time, you have to choose, and not choosing is what makes us to try to cramp more and more things. So it is a lost battle. This reminds me the concept of how many f* you have.

As well, we are always thinking in the future. Being more present helps you to get things in better perspective. The time we have in Earth is ridiculous compared with a stone or the universe so that should give you the freedom (instead of the fear of not having enough) of focusing in your correct things. We need meaningfulness and connection. And something I am reading/listening quite often, we need action (and not hopping).

Questions offered in the book:

1- Where in your life or your work are you currently pursuing comfort, when what’s called for is a little discomfort?

— That hit me. Since my last move, I feel more comfortable because I have some discomfort/challenges. Before I felt uncomfortable and in theory “I have (nearly) all”

2- Are you holding yourself to , and judging yourself by, standards of productivity or performance that are impossible to meet?

— Somehow yes, I have so many books to read and so many things I would like to learn, so many certifications to get. Still I am pretty sure I would never be happy if achieved all that.

3- In what ways have you yet to accept the fact that you are who you are, not the person you think you ought to be?

— That helped, since I started to accept me and loving me as I am, I drop a lot of emotional weight. And to be honest, just telling me that I can do a hard route when climbing, pushes me to send it and improve. But this is not done, still lot to do, you know, dating….

4- In which areas of life are you still holding back until you feel like you know what your are doing?

— The winner is dating/relationships.

5- How would you spend your days differently if you didnt care so much about seeing your actions reaching fruition?

— I would like to live in the country side. Like this. Work in the fields and technology, and having a partner to share that life.

It is not hopping, it is doing.

I leave a lot of things away, I need to read it again.

LLM n C, 1.6nm, xz vul, turing 2024, let’s encrypt, chatdev, Ethernet vs IB, Slingshot, Tailscale ssh, videos, 42 rules, CNI, Cilium

Origins of deep learning: interesting post. At the beginning all was Matlab and CPU bounded. repo

LLM in C: post and repo.

A16: 1.6nm process for 2026. More frequency, less power.

xz vulnerability repo: Something I need to check in the VP

Turing Award 2024: zero-knowledge-proof.

Cloudflare and Let’s Encrypt’s certificate change: I haven’t heard of this until recently. I use Let’s Encrypt so as far as I can read, makes sense what they are doing. But didnt know 2% Cloudflare customer were using the “cert”

ChatDev: Communicate agents for software development. I am a not a developer but I would use this just as a starting point If I have any idea for a project. I would remove the C-suite agents, at least for low level projects.

IB vs Ethernet: A bit of bias here (the author is from Broadcom -> Ethernet). I have no hands-on experience with IB, but I have read the cables are not cheap… Let’s see when UltraEthernet gets into the market. Another view.

Slingshot and Juniper: A bit of bias again as HP bought Juniper. So how will these interconnects fade inside the company? As far as I know, most supercomputers use some “special” interconnect so not much ethernet there. But the money nowadays is in AI infra… Paper for slingshot (haven’t read it)

Tailscale SSH, wireguard throughput: These are things I should a spend a bit of time one day and consider if I should use them (I dont like it is not opensource though). This netmaker?

Videos:

Jocko Willink: Discipline = Freedom. Remember but not dwell. Good leader, delegate. Be a man -> take action, bonding (pick your activity)

Jimmy Carr: Imposter syndrome each 18 months, so you have to stand-up. People crave the success not the journey. Teaching comedy good for communicating.

Sam Altman – Stanford 2024: First time I see him talking. It has some funny moments. More powerful computers. I missed a question about opensource LLM and closed ones.

Find a girlfriend: I know just a little bit about the person (I want to read one of his books) from other books and videos. I would think he would have already a girlfriend or family. From the three methods, definitely, the face to face approach in the street looks so much better (and that’s what I would like to do)

Jordan Peterson original 42 rules

CNI performance: I have used kubernetes since I studied for CKAD but still I am interested in the networks side. I didn’t know about Kube-router and it did great! I am bit surprised with Calico as I have read more and more about Cilium.

Cilium for network engineers. I have to read this fully (worried that Cisco bought it…)
