- What happened to ChatGPT the other day? It wasn't DNS, but it wasn't not DNS either. (Try Parity)
OpenAI deployed a new system that had been running happily on their test servers for some time. About twenty minutes in, things started going horribly wrong, with the monitoring system that reports on all things production taking over and then taking out the production servers, because it had a hidden scaling problem that never showed up on the smaller test environment.
And with the monitoring process eating up all the bandwidth on the control network, the simple changes they needed to make to fix the problem couldn't be done because OpenAI's internal DNS was down.
Lesson of the day: Hard code all your IP addresses in your software.*

- Nvidia has made its Jetson Orin Nano robotics development kit half the price and also up to twice as fast. (Serve the Home)
If you already have one, you can download the speed upgrade. Which is odd, because it doubles your memory bandwidth, which is a hardware function.
- AMD's Strix Halo laptop chip, with 16 Zen 5 CPU cores and 40 RDNA3.5 graphics cores, is coming soon to the Asus ROG Flow Z13... Tablet. (Hot Hardware)
Which is not as surprising as it seems because the current model of the Z13 can include dedicated a Nvidia RTX 4060, so a Strix Halo tuned to the lower power end of its spectrum would not use any more power than the current CPU and GPU combination.
- The Minisforum MGA1 is an external graphics card / dock thingy that dramatically speeds up laptops and mini-PCs except. (Notebook Check)
It's about as fast as a laptop version of the RTX 3080, but can only be connected via OCuLink. If your laptop or mini-PC doesn't have OCuLink - and most don't - it's a paperweight.
OCuLink is pure external PCI Express, so it's simpler, cheaper, and faster than Thunderbolt, but also a lot less common.

At one of my previous jobs, we had all the server names and their IP addresses in a database to avoid DNS issues. And then we found that in reality, 99% of our DNS issues prevented us from reaching the database.

Place I used to work at had one last test site that was full production sized, just to prevent this type of thing from happening.

A software change providing a speed increase doesn't surprise me. I've worked with processors that had programmable internal system clocks, as well as processors with configurable memory interfaces that included a programmable number of wait states added to memory accesses.
As an extreme example of companies deliberately limiting performance, back in the early 1980s, I used to work for a company that made dedicated word processors with Motorola 6800-based terminals and Intel 8086-based central servers. These were sold with several available speeds, and when a customer ordered a speed upgrade, a technician would go to the customer site and remove one or more boards that inserted wait states onto the memory bus.
