No End Of Excitement Edition
- Coles is doing home deliveries again. My chickie nuggies and fried rices arrive Tuesday.
- USB 4.0 will support DisplayPort 2.0 with bit rates up to 80Gbps. (AnandTech)
That's in one direction over an active cable (the same as Thunderbolt 3). With a regular USB cable it drops to just 40Gbps.
At full speed it can handle 8K 60Hz at 30 bits per pixel. With a normal cable it can do 8K with 4:2:2 colour or 5K 60Hz.
- The 48-core Threadripper 3980X probably doesn't exist. (Tom's Hardware)
But possibly not. My first reaction was that AMD wouldn't configure it with 192MB of L3 cache - which would mean six 8-core dies - but instead with eight 6-core dies and a total of 256MB of cache.
But on the Epyc side of things they offer both options, so that doesn't rule it out as a real leak.
- 18 plugins for writing Python in VS Code. (Switowski)
Or - bear with me - you could just use PyCharm which costs all of free for the Community Edition.
- Half of Americans aren't complete idiots. (Ars Technica)
- The US government has finally recognised Amazon's market-leading efforts in selling counterfeit crap to everyone in the universe. (Politico)
Just look up SD cards. The site is inundated with fakes.
- Holy crap bandwidth from Google Cloud is expensive.

From an example I found real quick, instead of adding 78 and 57 to get 135, you can add 70 and 50 to get 120, then ad 8 and 7 to get 15, then add those two intermediate sums to get the final answer. Or the one that really troubles people, instead of subtracting 28 from 86 the old-fashioned way in the video, you notice that 28 + 2 = 30, and 30 + 10 = 40 and 40 + 40 = 80, and if you add 6 more, you get 86. So now add up the 2 and the 10 and the 40 and the 6 to get 58, and there's your result. It's kinda-sorta similar to the way I would do that in my own head, although backwards, and also as if someone with a low IQ listened to my explanation and misunderstood it.

Even now, 40 years on, I can say "6*9=54" without having to think about it.
