ELIZA bot: original source code found
The History and Mystery Of Eliza With Jeff Shrager - CoRecursive Podcast
Eliza, the chatbot, was built in 1964, and she didn’t answer questions like Alexa or Siri. She asked questions. She was a therapist chatbot and quickly became famous after being described in a 1964 paper.
But here is the mystery. We’re not sure how the original version worked. Joseph Weizenbaum never released the code. But Jeff tracked it down, and some of the things we thought we knew about Eliza turned out to be wrong.

DARPA: Bitcoin, Ethereum in-security research
Pentagon finds concerning vulnerabilities on blockchain | TechRepublic
"Defense Advanced Research Projects Agency (DARPA), engaged Trail of Bits—a security research organization—to investigate the blockchain. Trail of Bits focused on Bitcoin and Ethereum, the two leading cryptocurrencies in the global market.
Trail of Bits says that it only takes four entities to disrupt Bitcoin and only two to disrupt Ethereum. Additionally, 60% of all Bitcoin traffic moves through just three ISPs. Outdated and unencrypted software and blockchain protocols were also identified by the organization."

Apple "silicon": M2 Chip vs M1
How Does Apple’s New M2 Chip Compare to the M1? - The Plug - HelloTech
Apple claims the new M2 chip is 18% faster than the M1 while using the same amount of power.
While the M2 is faster than the original M1, it is not the fastest Apple silicon chip on the market. Since Apple launched the first M1 chip, the company quickly followed it up with the M1 Pro and the M1 Max in 2021, as well as the M1 Ultra in 2022.

Cloudflare Workers + WebAssembly + R2 storage
Episode #142: Cloudflare Workers with Michael Hart - Serverless Chats Podcast
"Under the hood, the Workers runtime uses the V8 engineOpen external link — the same engine used by Chromium and Node.js. The Workers runtime also implements many of the standard APIs available in most modern browsers.
The differences between JavaScript written for the browser or Node.js happen at runtime. Rather than running on an individual’s machine (for example, a browser application or on a centralized serverOpen external link), Workers functions run on Cloudflare’s Edge NetworkOpen external link - a growing global network of thousands of machines distributed across hundreds of locations."
V8 orchestrates isolates: lightweight contexts that provide your code with variables it can access and a safe environment to be executed within. You could even consider an isolate a sandbox for your function to run in.
A single runtime can run hundreds or thousands of isolates, seamlessly switching between them. Each isolate’s memory is completely isolated, so each piece of code is protected from other untrusted or user-written code on the runtime. Isolates are also designed to start very quickly. Instead of creating a virtual machine for each function, an isolate is created within an existing environment. This model eliminates the cold starts of the virtual machine model.

Announcing support for WASI on Cloudflare Workers
Cloudflare R2 Storage includes full S3 API compatibility
Traditional object storage charges developers for three things: bandwidth, storage size and storage operations.
R2 builds on Cloudflare’s commitment to the Bandwidth Alliance, providing zero-cost egress for stored objects — no matter your request rate. Egress bandwidth is often the largest charge for developers utilizing object storage and is also the hardest charge to predict. Eliminating it is a huge win for open-access to data stored in the cloud.
That doesn’t mean we are shifting bandwidth costs elsewhere. Cloudflare R2 will be priced at $0.015 per GB of data stored per month — significantly cheaper than major incumbent providers.
In 2017 Cloudflare launched Cloudflare Workers, a serverless computing platform for creating new applications, augmenting existing ones, without configuring or maintaining infrastructure. It has expanded to include Workers KV, a low-latency key-value data store; Cron Triggers, for scheduling Cron jobs;

db: Litestream + SQLite vs Postgres
benbjohnson/litestream: Streaming replication for SQLite. @GitHub (GoLang!)
Litestream is a standalone streaming replication tool for SQLite. It runs as a background process and safely replicates changes incrementally to another file or S3. Litestream only communicates with SQLite through the SQLite API so it will not corrupt your database.

JVM, CLR, PVM => WASM (WebAssembly)?
Understand WebAssembly: Why It Will Change the Web - Strumenta
WebAssembly, or wasm, is a low-level bytecode format for in-browser client-side scripting. If you are writing a compiler for a programming language one option is to target a platform, like the JVM or .NET, and compile your language to the target bytecode. WebAssembly occupies the same role, so when you compiling to WebAssembly you are making your software available for all platforms where it is supported, in other words all browsers.Java virtual machine - Wikipedia

Native AOT in .NET 7
ReadyToRun deployment overview - .NET | Microsoft Docs
.NET application startup time and latency can be improved by compiling your application assemblies as ReadyToRun (R2R) format. R2R is a form of ahead-of-time (AOT) compilation.
R2R binaries improve startup performance by reducing the amount of work the just-in-time (JIT) compiler needs to do as your application loads. The binaries contain similar native code compared to what the JIT would produce. However, R2R binaries are larger because they contain both intermediate language (IL) code, which is still needed for some scenarios, and the native version of the same code. R2R is only available when you publish an app that targets specific runtime environments (RID) such as Linux x64 or Windows x64.

Terraform SDK
Home - Plugin Development | Terraform by HashiCorp
Terraform is logically split into two main parts:
Terraform Core: This is the Terraform binary that communicates with plugins to manage infrastructure resources. It provides a common interface that allows you to leverage many different cloud providers, databases, services, and in-house solutions.
Terraform Plugins: These are executable binaries written in Go that communicate with Terraform Core over an RPC interface. Each plugin exposes an implementation for a specific service, such as the AWS provider or the cloud-init provider. Terraform currently supports one type of Plugin called providers.

A Multipurpose Database For Transactions And Analytics To Simplify Your Data Architecture With Singlestore | Data Engineering Podcast
SingleStore Joins Bytecode Alliance
“The key change required to handle large data is to push the compute to the data. WASM allows you to move the compute inside the database, which can dramatically change how databases and analytical systems interact. It is going to open up all sorts of opportunities to simplify analytics, make them faster and more interactive, and lower TCO.” - Jordan Tigani, Chief Product Officer at SingleStore
SingleStore - Wikipedia
SingleStore (formerly MemSQL) is a cloud-native database designed for data-intensive applications.[3] A distributed, relational, SQL database management system[4] (RDBMS) that features ANSI SQL support, it is known for speed in data ingest, transaction processing, and query processing.[5][3]
SingleStore primarily stores relational data, though it can also store JSON data, graph data, and time series data. It supports blended workloads, commonly referred to as HTAP workloads, as well as more traditional OLTP and OLAP use cases. For queries, it compiles Structured Query Language (SQL) into machine code. The SingleStore database engine can be run in various Linux environments, including on-premises installations, public and private cloud providers, in containers via a Kubernetes operator, or as a hosted service in the cloud known as SingleStore Managed Service

by Tim Bray, one of the original co-authors of the XML spec) finds a use case for generics in his Quamima pattern matching library, only to find that there are some ‘bumps in the road’ which he shares here for everyone’s benefit.
Tim concludes: “I don’t hate Go’s generics, which is actually pretty strong testimony given that I spent the best part of a couple of days fighting all the stuff described above. But, my guess is the Go generics story is isn’t finished yet.”
