Classic Brownie

This was my first “brownie” many years ago, and shame on me, I haven’t tried for several years. So this deserves to be here. Super easy to do.

Ingredients

  • 300g chocolate (I used 90% dark)
  • 300g sugar
  • 200g butter
  • 6 medium eggs
  • 90g all-purpose flour
  • Tahini (extra)

Process:

  • Pre-heat oven at 160C
  • Mix eggs and sugar, very well. Use a handmixer if you can.
  • In a low-medium heat pan, melt butter and chocolate.
  • Add choco-mix to the egg-mix and mix again very well, use a wooden spoon.
  • Add the flour and mix well again
  • Wet a sheet of baking paper and put in the your baking mold.
  • Pour the mix in the mold, be sure it is even
  • Extra: pour the tahini (it has to be a bit runny) in the top and with a wooden stick or similar mix it in the surface like below
  • Bake for 20m. This is critical, dont over bake it! If it is a bit runny in the middle is fine. If it is dry, then you over did it.

My result. It was really good!

Let is cool down for a couple of hours before cutting.

Dating summary: Really good all points, most of them I feel them or experienced.

Backwards Law: Emotions are weather, you can’t control them. You can control what you do with the emotions

You never know who you are until you have adversity in life.

SR-IOV:

SR-IOV (Single Root I/O Virtualization) is an extension to the PCI Express specification that lets a single physical device, like a network adapter, present itself as multiple separate virtual devices. Each virtual machine gets its own direct access to the hardware, bypassing the hypervisor’s software layer and delivering network performance close to what you’d get on bare metal. It was designed by the PCI-SIG standards body specifically to solve the performance bottleneck that virtualization creates when many VMs share one network card.

From this article about Meta Superintelligence, came across this link about Meta backbone designs at scale for EBB

opensm: I can’t find many blog posts with real hands-on about IB things. And this is a good one. It doesnt just show you the configuration, but the problems you can find. It seems it is better to use the Mellanox’s opensm

  • systemctl status opensm –no-pager
  • sudo sminfo
  • sudo ibnetdiscover
  • sudo saquery NR | grep -E “lid|NodeDescription”
  • sudo tail -f /var/log/opensm.log

IB cable EEPROM: Interesting how critical can be having the correct cable from the EEPROM.

 The label on a cable is marketing. The EEPROM inside it is a contract, and InfiniBand only honors contracts.
