• Dell has a new range of XPS desktop systems, using DDR5. For some reason. You can't buy DDR5 RAM anywhere, but you can configure a system on Dell's website with up to 128GB for an extra $1300. And it doesn't change the delivery date, which is this time next month. Whether that's realistic or not is an open question, but my latest Dell order left the factory a day ahead of schedule, so they seem to have some idea of the extent of the delays in their pipeline.
  
  But there's the question of how much faster memory actually helps and the answer is not much. (Tom's Hardware)
  
  On a range of synthetic and real-world benchmarks, upgrading from DDR4-2666 to DDR4-4600 improved performance by about 5%.
  
  
  
• Gluten free nuggies and Special K are out of stock again. But I do have eight pounds of gluten free jelly beans and jelly babies, since that order arrived unimpeded, along with that little mixer I mentioned and some audio cables for it.
  
  What hasn't arrived yet is my new keyboard, and the . key on the current one just required percussive maintenance again.
  
  

• AMD just released an update to their Linux drivers for Radeon 9500, 9700, and 9800 cards. (Phoronix)
  
  Which came out in 2002.
  
  
  
• Speaking of Linux and AMD, the company just confirmed that their 4th generation "Genoa" server CPUs will support 12 channel DDR5 RAM. (Tom's Hardware)
  
  Not by press release. It's in their Linux kernel patches, the number one source for confirmed leaks these days.
  
  
  
• Australia's stupid federal government is debating new regulations for stupid social networks. (ZDNet)
  
  The article makes my head hurt. Everyone involved is both lying and stupid.
  
  
  
• Now they know how many holes it takes to fill the Albert Hall. (Quanta)

  The first major advance on the Arnold conjecture took place decades later, in the 1980s, when a young mathematician named Andreas Floer developed a radical new way of counting holes. Floer's theory quickly became one of the central tools in symplectic geometry. Yet even as mathematicians used Floer's ideas, they imagined it should be possible to transcend his theory itself — to develop other theories in light of the new perspective that Floer opened up.

  Nope, no idea.
