WebRTC: Zoom on Web

Zoom on Web: getting connected with advanced web technology - YouTube

Zoom on Web: WebAssembly SIMD, WebTransport, and WebCodecs @InfoQ

"At the recent [ live event], Google V8 product manager Thomas Nattestad explained some of the proposed additions to the web to support Zoom and other video conferencing features within the web browser.

Nattestad explains that WebRTC was standardized nearly ten years ago and provides a full-stack solution for video conferencing in all evergreen browsers. Unfortunately, WebRTC has limitations, and many services like Zoom would benefit from low-level access to various APIs."

Rome for JavaScript & TypeScript

Introducing Rome

"Rome is a monolithic tool containing functionality that has traditionally been separate tools in the frontend ecosystem. We call this a toolchain. It is not a collection of existing tools, but completely custom, built largely from scratch, contained entirely in a single package and codebase.

Rome is designed to replace Babel, ESLint, Webpack, Prettier, Jest, and others."

Elon Musk about PayPal advantage

APPENDIX 2 - Elon Musk: Tesla, SpaceX, and the Quest for a Fantastic Future (2017)

"Almost no one understands how PayPal actually worked or why it took off when other payment systems before and after it didn’t. Most of the people at PayPal don’t understand this. The reason it worked was because the cost of transactions in PayPal was lower than any other system. And the reason the cost of transactions was lower is because we were able to do an increasing percentage of our transactions as ACH, or automated clearinghouse, electronic transactions, and most importantly, internal transactions. Internal transactions were essentially fraud-free and cost us nothing. An ACH transaction costs, I don’t know, like twenty cents or something. But it was slow, so that was the bad thing. It’s dependent on the bank’s batch processing time. And then the credit card transaction was fast, but expensive in terms of the credit card processing fees and very prone to fraud. That’s the problem Square is having now.
So because about half of PayPal’s transactions in the summer of 2001 were internal or ACH transactions, then our fundamental costs of transactions were half because we’d have half credit cards, we’d have that and then the other half would be free."

Acronyms Seriously Suck - Elon Musk

Acronyms Seriously Suck - Elon Musk · GitHub

From time to time, Musk will send out an e-mail to the entire company to enforce a new policy or let them know about something that's bothering him. One of the more famous e-mails arrived in May 2010 with the subject line: Acronyms Seriously Suck:
There is a creeping tendency to use made up acronyms at SpaceX. Excessive use of made up acronyms is a significant impediment to communication and keeping communication good as we grow is incredibly important. Individually, a few acronyms here and there may not seem so bad, but if a thousand people are making these up, over time the result will be a huge glossary that we have to issue to new employees. No one can actually remember all these acronyms and people don't want to seem dumb in a meeting, so they just sit there in ignorance. This is particularly tough on new employees.
That needs to stop immediately or I will take drastic action - I have given enough warning over the years. Unless an acronym is approved by me, it should not enter the SpaceX glossary. If there is an existing acronym that cannot reasonably be justified, it should be eliminated, as I have requested in the past.
For example, there should be not "HTS" [horizontal test stand] or "VTS" [vertical test stand] designations for test stands. Those are particularly dumb, as they contain unnecessary words. A "stand" at our test site is obviously a test stand. VTS-3 is four syllables compared with "Tripod", which is two, so the bloody acronym version actually takes longer to say than the name!
The key test for an acronym is to ask whether it helps or hurts communication. An acronym that most engineers outside of SpaceX already know, such as GUI, is fine to use. It is also ok to make up a few acronyms/contractions every now and again, assuming I have approved them, e.g. MVac and M9 instead of Merlin 1C-Vacuum or Merlin 1C-Sea Level, but those need to be kept to a minimum.

COBOL@ WASM @ V8 @ CloudFlare Edge

Cloudflare Workers Now Support COBOL

"As old as COBOL is (60 years old prog. language), it is still heavily used in information management systems and pretty much anywhere there’s an IBM mainframe around. Three years ago Thomson Reuters reported that COBOL is used in 43% of banking systems, is behind 80% of in-person financial transactions and 95% of times an ATM card is used. They also reported 100s of billions of lines of running COBOL.

COBOL can now be used to write code for Cloudflare’s serverless platform Workers."

        01 HTTP_OK   PIC X(4)  VALUE "200".
        01 OUTPUT_TEXT PIC X(14) VALUE "Hello, World!".
            CALL "set_http_status" USING HTTP_OK.
            CALL "append_http_body" USING OUTPUT_TEXT.
        STOP RUN.

Cloudflare Edge Workers vs AWS Lambda@Edge, Azure, GCP Serverless

Cloudflare Wants to Eat AWS’s Serverless Lunch | Data Center Knowledge

" cloud service from Cloudflare ... beats competing services by the three cloud giants – AWS, Azure, and Google Cloud – on both performance and price...

The new service builds on ... Workers platform for serverless computing at the edge. Called Workers Unbound, it lifts the limitations Workers had for how resource-intensive a workload it could support and how long an execution time it would allow."

Cloudflare Takes On AWS Lambda@Edge With A Cheaper And Faster Serverless Platform

Serverless Performance: Cloudflare Workers, Lambda and Lambda@Edge

Workers is built on V8 isolates, which are significantly faster to spin up (under 5ms) than a full NodeJS process and have a tenth the memory overhead. 


How Can Serverless Computing Improve Performance? | Lambda Performance | Cloudflare

"Cloudflare Workers respond very quickly, typically in under 200 milliseconds, when cold starting. In contrast, both Lambda and Lambda@Edge functions can take over a second to respond from a cold start.

The differences are largely due to the fact that Cloudflare Workers run on Chrome V8 rather than Node.js. Node.js is built on top of Chrome V8, takes longer to spin up, and has more memory overhead. Usually V8 instances take less than 5 milliseconds to spin up."

AWS CDK + Terraform

Cloud Development Kit Can Now Generate Terraform Configurations Using TypeScript and Python @InfoQ

"AWS, HashiCorp, and Terrastack collaborated to release a preview of the Cloud Development Kit (CDK) for Terraform, or cdktf. Developers can use programming languages like Python or Typescript to manage infrastructure as code. cdktf generates a Terraform configuration in JSON that can deploy resources with a "terraform apply" command. Also, cdktf supports any existing modules and providers from the Terraform registry to deploy resources to AWS, Azure, or Google Cloud."
