Daily Tech news 23 March 2022

• Latest house I've looked at has a garage as large as my entire current house including the garage. The rest of the house is about two and a half houses. And it's half the price of my current house. And has gigabit internet available.
  
  Not that you actually get gigabit speeds on gigabit internet here, but if you sign up for the half-gigabit plan you can come pretty close to that.
  
  
  
• Nvidia today announced its new Hopper GPU architecture which can deliver a petaFLOPS sort of on a single chip. (AnandTech)
  
  I say sort of because that's measuring 16-bit floating point which is fine for neural networks but useless for computational fluid dynamics. With 64-bit values the vector unit delivers 30 TFLOPS which is very good but doesn't sound as impressive.
  
  It's not shipping yet and you won't be able to buy one when it does - this is for servers and supercomputers. In fact, this architecture might not be coming to the desktop at all, since there's another product announcement coming for that later this year.

• Nvidia also announced a 144-core Arm CPU that you also can't get. (Tom's Hardware)
  
  The Grace CPU Superchip (that's its name) is based on Arm's latest N2 core and is made up of two 72 core chips with a 900GB/s interconnect. Nvidia say it is 1.5x faster than AMD's current 64 core chips which is not all that impressive when it has 2.25x as many cores and won't actually ship until next year by which time AMD's Zen 4-based 96 and 128 core CPUs will likely be available.
  
  
  
• The great promise of Web 3 is decentralisation. The great promise is a lie. (Neel Chauhan)

  Blockchain Sucks, Period

  Pretty much, yeah.
  
  
  
• New Browser-in-the-Browser attacks are nearly undetectable to idiots. (The Hacker News which is not the same site as Hacker News)
  
  Basically the attack pops up a fake login window within your web page. The thing is, if you use a password manager - including the one built in to your browser of choice - it will refuse to have anything to do with the fake login window because it is obviously fake.
  
  Also the fake window can't be moved outside your current browser tab.
  
  Also the fake window will ignore any theme settings you might have configured on your computer.
  
  Also if you drag it around it won't behave like a real window.
  
  
  
• The goal of crypto is not to play games with million dollar pictures of monkeys. (Benzinga)
  
  That's a quote from the creator of Ethereum.
  
  
  
• Nvidia's new Jetson AGZ Orin is a robotics development board for hobbyists with too much money. (Hot Hardware)
  
  Ranging in price from $899 to $1999 you might be better off with a Pi Pico.
