Daily Tech News 22 January 2023

• Is Apple really scanning images on your Mac? No. I mean, yes they are, clearly, we can see the network traffic sending data to Apple's servers, but we're going to answer no anyway. (Eclectic Light)
  
  Uh huh.
  
  
  

• Don't use potatoes or cheese to cool your video card. (Tom's Hardware)
  
  Toothpaste and ketchup sure, but not potatoes or cheese.
  
  
  
• AMD's new Epyc Genoa 9654 is top of the list on PassMark. (WCCFTech)
  
  The fastest competing chip - until Intel's Sapphire Rapids shows up for real - comes in at #25. The fastest Arm-based chip is the 128 core Neoverse N1, coming in at #60, a little behind AMD's 12 core 65W Ryzen 7900.
  
  Which suggests to me something is wrong there, because it shouldn't be that slow. Though PassMark scores don't scale anything like linearly with core count.
  
  
  
• Using the Raspberry Pi Pico DMA unit as a general-purpose processor. (Cornell)
  
  It can execute code about as fast as an Arduino - or my old Amiga 3000 - without any ability to execute code.
  
  
  
• Twitter is (not) down to about 550 full-time engineers. (CNBC)
  
  While Twitter has said the numbers are incorrect, I'd like to believe this part:

  The company's trust and safety team, which makes policy recommendations, design and product changes with the aim of keeping all of Twitter's users safe, is down to fewer than 20 full-time employees.

  That would be good news indeed.
