• ⁨Comment⁩ on ⁨Study finds health risks in switching ships from diesel to ammonia fuel⁩ ⁨⁨3⁩ ⁨months⁩ ago⁩:

  The funny thing about air conditioning fluids, is that we are actually moving from HCFC to propane and ammonia, due their green house effect.

  Aka the thing that CFC were supposed to replace because they were safer.

  It is a circle.

  This isn’t true anymore, Intel dropped AVX512 since they moved to Big+Small cores design while AMD actually implemented it with Zen 4.

  If you already didn’t know, you can run locally some small models with an entry level GPU.

  For example i can run Llama 3 8B or Mistral 7B on a 1060 3GB with Ollama. It is about as bad as GPT-3 turbo, so overall mildly useful.

  Although there is quite a bit of controversy of what is an “open source” model, most are only “open weight”

• ⁨Comment⁩ on ⁨The first EV with a lithium-free sodium battery hits the road in January⁩ ⁨⁨10⁩ ⁨months⁩ ago⁩:

  I don’t find the source anymore, but i saw a lifetime analysis about sodium ion batteries. Overall they are slighly worse than lithium ion due to higher energy input required during fabrication, despite better mineral availability.

  The most common Na-ion batteries use Prussian Blue.
