GTC 2026 Build HP Research Cluster: s81731 – Very good presentation going to the low details of tools to use to build a GPU cluster. Storage is VAST, NVIDIA Spectrum-X (Ethernet), N-S is a different vendor, issues with L1 (maybe co-package optics can improve that?). SU = scalable Units. 64 spines upfront

XPO Cooled Optics: paper. xpomsa 12.8T per optic…

Secret behind credit cards: I would never thought how the credit card technology started…

Good laugh in the road:

Reclaim life – Bryan Johnson:

  • you can do hard things
  • create a bed time routine
  • begin your day with purpose
  • future-proof your body
  • treat food like medicine
  • kill the distractions (need to controle youtube…)
  • Remove isolation (I know…)
  • stop watching more youtube videos and motivation things (like above… action)

Longevity Lie: Longer life without quality is not life. Agree current medicine wants you to live longer but hooked to medicines… at least when you are old… Keep muscle!

Alex Honnold: Diary CEO and Dan Churchill.

XZ hack: very good narrative about the social side of this hacking (although the technical is out of my league

Mark Manson 42:

Need to stop reading bad books: ryan holiday

Grip Strength: A reminder….

Stay Fit: 2×45 a week

Linux Laptop: Frame.work – Really smooth design…

Bulgaria Physics Teacher: There are things you need to work hard no matter what…

Obama focus:

Husband never to ask: Random things from youtube… but interesting

Synopsys: Didnt know this company but it uses by all major chip producers and designers…. (NVIDIA, AMD, Meta, etc)

I dont look like a navy seal: just get it, do very hard things but just concentrate in your next goal… it is breakfast. Little victories. Positive aptitude. Your worse enemy are your doubts, fears and everybody else that doesnt believe on you. Keep moving forwards.
