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.
Let’s compare EC2 instance types with 16GB RAM:
| Instance | vCPUs | ECU | Baseline Performance per 1 vCPU | Memory | Price/Hour (Linux) | Price/Hour (Windows) |
|---|---|---|---|---|---|---|
| t3.xlarge | 4 | Variable | 40% | 16 GiB | $0.166 | $0.24 |
| t2.xlarge | 4 | Variable | 22.5% | 16 GiB | $0.186 | $0.227 |
| m5.xlarge | 4 | 16 | n/a | 16 GiB | $0.192 | $0.376 |
| r5.large | 2 | 8 | n/a | 16 GiB | $0.126 | $0.218 |

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

Self-Driving: Waymo vs Tesla?
"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."

faster TypeScript
Episode #83: Serverless and TypeScript with Tim Suchanek - Serverless Chats Podcast
an interesting podcast story about TypeScript used for “ORM” Prisma (usually GraphQL)
mentioned “project swc” that is using Rust for making faster TypeScript compiler (20x ?)
as well as using AssemblyScript (subset of TypeScript) and Rust for WASM on CDNs.
He also mentioned “IOTS” a newer/better way for data validation based on TypeScript during runtime, better than “yup” by skipping for multiple formats of validation metadata.

Sony begins testing its electric car concept on public roads
Sony has, however, worked with some significant players on the project. These include vehicle manufacturer Magna Steyr.
Indeed, in another video published by Sony on Monday, Frank Klein, the president of Magna Steyr, described the Vision-S as “just the starting point of our joint cooperation.”"Magna Steyr AG & Co KG is an automobile manufacturer based in Graz, Austria, where its primary manufacturing plant is also located. It is a subsidiary of Canadian-based Magna International and was previously part of the Steyr-Daimler-Puch conglomerate.
Magna Steyr engineers, develops and assembles automobiles for other companies on a contractual basis; therefore, Magna Steyr is not an automobile marque. In 2002, the company absorbed Daimler AG's Eurostar vehicle assembly facility. With an annual production capacity of approximately 200,000 vehicles as of 2018,[1] it is the largest contract manufacturer for automobiles worldwide.[2] The company has several manufacturing sites, with its main car production in Graz in Austria."
Hyundai Motor and Apple are set to make a new agreement on electric cars by March, Reuters writes, citing local newspaper Korea IT News.
The companies will likely start production by 2024.
The report follows a statement from last week where Hyundai Motor said it was in early talks with Apple, after a local media outlet had reported that the two were aiming at 2027 for a launch of the car.
EV: VW sales numbers

JavaScript: "Stimulus" Framework
Stimulus inspired Catalyst, GitHub’s web component set of patterns.
Stimulus is a JavaScript framework with modest ambitions. It doesn’t seek to take over your entire front-end—in fact, it’s not concerned with rendering HTML at all. Instead, it’s designed to augment your HTML with just enough behavior to make it shine.
Stimulus’ concept of controller will be familiar to users of Rails and Laravel. Stimulus originates from some of the developers who created Rails. Direct DOM updates and using DOM state as the source of truth will equally be familiar to long-time programmers who started web development with jQuery and jQuery plugins. The Basecamp team behind Stimulus reported using in the past a variety of techniques and libraries such as jQuery for building Basecamp.
<!--HTML from anywhere-->
<div data-controller="hello">
<input data-hello-target="name" type="text">
<button data-action="click->hello#greet">
Greet
</button>
<span data-hello-target="output">
</span>
</div>
That HTML source is mapped to the following JavaScript code:
// hello_controller.js
import { Controller } from "stimulus"
export default class extends Controller {
static targets = [ "name", "output" ]
greet() {
this.outputTarget.textContent =
`Hello, ${this.nameTarget.value}!`
}

AWS Open Source fork of Elasticsearch & Kibana
"Last week, Elastic announced they will change their software licensing strategy, and will not release new versions of Elasticsearch and Kibana under the Apache License, Version 2.0 (ALv2). Instead, new versions of the software will be offered under the Elastic License (which limits how it can be used) or the Server Side Public License (which has requirements that make it unacceptable to many in the open source community). This means that Elasticsearch and Kibana will no longer be open source software. In order to ensure open source versions of both packages remain available and well supported, including in our own offerings, we are announcing today that AWS will step up to create and maintain a ALv2-licensed fork of open source Elasticsearch and Kibana."
