AWS EC2 T3 vs T2
New T3 Instances – Burstable, Cost-Effective Performance | AWS News Blog
Amazon EC2 T3 Instances: When to Select Them for Your Workloads | Densify
AWS EC2 T3 instances offer a balance of compute, memory, and network resources, and are designed to provide a baseline level of CPU performance with the ability to burst above that baseline when needed.T3 instances are unlimited by default, meaning that, while they won’t be throttled, they can rack up additional costs if you run CPU-hungry workloads.
T3 instances are powered by the Nitro system which means that they support network and EBS bursting.
Cost Comparison of T3 vs T2, M5, & R5 Instances
Should You Use T3 for Your Workloads?
Let’s compare EC2 instance types with 16GB RAM:
Let’s compare EC2 instance types with 16GB RAM:

RISC-V: Open Source GPU
Free Open Source GPU Under Development for RISC-V | Tom's Hardware
The RISC-V architecture enables small companies to develop purpose-built processors and microcontrollers without paying a royalty. There are numerous free and commercial IP building blocks for RISC-V-based system-on-chips (SoCs), but the portfolio lacks a graphics option. This will change in a few years as a group of enthusiasts has started developing an open-source GPU based on the RISC-V architecture.

DPU: Data Processing Unit, NVIDIA DOCA
First used to be "Floating Point Unit" coprocessor (Intel 287), then GPU (Graphics Processing Unit),
and now NVidia comes with "Data Processing Unit" to help network communication in cloud / data centers. And similar to previous solution for Machine Learning SDK (NVIDIA CUDA),
for "DPU"s they have now developed "DOCA SDK". This could be part of the reason for very expensive purchase of ARM company.
Amazon / AWS has also developed similar specialized solution for AWS EC2 compute instances
called "Nitro", that offloads network, security and management to a separate board, feeing full CPU and GPU power for user tasks.
What's a DPU?
System on a chip that combines:
- Industry-standard, high-performance, software-programmable multi-core CPU
- High-performance network interface
- Flexible and programmable acceleration engines

Tesla Model S & X redesign
Tesla says the new Model S is the world's most aerodynamic production car
"There's a lot of new stuff to talk about when it comes to the Tesla Model S, which today received its most major update since it was first unveiled in 2012. It's got a completely new interior with a crazy steering wheel, lots of updated tech and a Plaid Plus model that promises over 520 miles of range. But buried in the deluge of info is a new superlative that Tesla is claiming: The updated Model S is the most aerodynamic production car in the world, with a drag coefficient of just 0.208."Refreshed Tesla Model S has a Knight Rider steering wheel - Roadshow

GCP CloudRun: WebSockets, HTTP-2 and gRPC
Cloud Run gets WebSockets, HTTP-2 and gRPC bidirectional streams | Google Cloud Blog
"new traffic serving capabilities for Cloud Run: end-to-end HTTP/2 connections, WebSockets support, and gRPC bidirectional streaming, completing the types of RPCs that are offered by gRPC. With these capabilities, you can deploy new kinds of applications to Cloud Run that were not previously supported, while taking advantage of serverless infrastructure. These features are now available in public preview for all Cloud Run locations."
"Lambda has supported runtimes for multiple languages such as JavaScript (Node.js), Java, Python, and Go and supports custom runtimes as well, whereas Cloud Run uses standard OCI images (commonly known as Docker images). Existing applications that are stateless and containerized should be deployable to Cloud Run as is."

Self-Driving: Waymo vs Tesla?
Waymo CEO dismisses Tesla self-driving plan: “This is not how it works” | Ars Technica
"For us, Tesla is not a competitor at all," Krafcik said. "We manufacture a completely autonomous driving system. Tesla is an automaker that is developing a really good driver assistance system."
For Musk, these two technologies exist along a continuum. His plan is to gradually make Tesla's Autopilot software better until it's good enough to work with no human supervision. But Krafcik argues that's not realistic.
"It is a misconception that you can just keep developing a driver assistance system until one day you can magically leap to a fully autonomous driving system," Krafcik said. "In terms of robustness and accuracy, for example, our sensors are orders of magnitude better than what we see on the road from other manufacturers."
