web: Massive JavaScript => performance now

The Unbearable Weight of Massive JavaScript – - Speaker Deck

The Unbearable Weight of Massive JavaScript | Ryan Townsend | 2023 - YouTube

how to use native web tools to improve web performance?
  • import maps
  • custom elements
  • scroll-snapping / scroll-linked animations
  • view transitions
  • navigations API

Follow Ryan on Mastodon @

For the past 10+ years, JavaScript frameworks and Single Page Applications have been marketed as the solution to all our performance, robustness and productivity problems, but things haven’t worked out the way we’d all hoped, have they?

* Simple marketing and ecommerce sites are still getting heavier and slower.

* Features fail in weird and wonderful ways meaning we need an ever-increasing array of tooling to monitor and debug problems.

* Teams armed with the latest Apple Silicon Macs, expensive CI tooling and complex build pipelines still can’t ship effectively.

But it’s not all doom-and-gloom: we live in a time of unprecedented opportunity to give our users a fantastic experience – the web platform has never been more capable than it is today.

Let’s look at what we can achieve by simplifying our web architecture, utilising new and upcoming Web Platform APIs and getting back to building fast, maintainable, user-friendly front-ends.

null safety? Dart vs Null References: The Billion Dollar Mistake

Understanding null safety | Dart

When Dart first launched, compile-time null safety was a rare feature needing a long introduction. Today, Kotlin, Swift, Rust, and other languages all have their own answers to what has become a very familiar problem...

If you run this Dart program without null safety, it throws a NoSuchMethodError exception on the call to .length. The null value is an instance of the Null class, and Null has no “length” getter. Runtime failures suck. This is especially true in a language like Dart that is designed to run on an end-user’s device. If a server application fails, you can often restart it before anyone notices. But when a Flutter app crashes on a user’s phone, they are not happy. When your users aren’t happy, you aren’t happy.

The Dart language is type safe: it uses a combination of static type checking and runtime checks to ensure that a variable’s value always matches the variable’s static type, sometimes referred to as sound typing. Although types are mandatory, type annotations are optional because of type inference.

Speaking at a software conference in 2009, Tony Hoare hyperbolically apologized for "inventing" the null reference:[26] [27]
"I call it my billion-dollar mistake. It was the invention of the null reference in 1965. At that time, I was designing the first comprehensive type system for references in an object oriented language (ALGOL W). My goal was to ensure that all use of references should be absolutely safe, with checking performed automatically by the compiler. But I couldn't resist the temptation to put in a null reference, simply because it was so easy to implement. This has led to innumerable errors, vulnerabilities, and system crashes, which have probably caused a billion dollars of pain and damage in the last forty years.[28]"

AI, HW: AMD stock?

I'm Buying AMD Over Nvidia Stock in 2024 (Here's Why) - YouTube

"#amd stock is setting up for a great 2024 and might even be a better buy than #nvidia ( #nvda stock ). Before the next AMD earnings call, let's compare AMD and Nvidia in terms of data center GPUs, which they both sell to power Generative AI applications like #chatgpt by #openai and then look at their automotive chips, like the kind AMD sells to #tesla ( #tsla stock ). With Nvidia facing so many supply limitations, the AI and semiconductor markets could be big enough for 2 winning stocks, potentially making AMD stock one of the best stocks to buy now!"

web Tetris vs. trauma

from book: Hidden Potential by Adam Grant 

"After people watch an especially upsetting film clip, over the next week they typically have six or seven disturbing flashbacks. But if they’re randomly assigned to play a few rounds of Tetris right after watching the scene, it cuts their flashbacks in half over the next week. Somehow, the act of rotating, moving, and dropping geometric blocks shields us from intrusive thoughts and aversive emotions"

the Tetris effect illustrates key features of scaffolding
Tetris... changes how your brain constructs mental imagery.
Tetris is effective scaffolding because it helps you bypass a particular challenge
to be effective, the critical period seems to be the next 24 hours

    Preact: mini React

    Learn Preact | Preact: Fast 3kb React alternative with the same ES6 API. Components & Virtual DOM.

    The simplest answer is that Preact provides the tools needed to construct complex web applications out of small reusable pieces called Components. What makes Preact unique is that it provides these tools in a uniquely small package: just 3kb of JavaScript code,

    Preact vs. React | Syncfusion Blogs

    If performance, speed, and size of the application are important factors to you, Preact is the ideal option. It is mainly utilized to create advanced web apps. For instance, Uber moved to Preact in production to make its PWA lightweight and powerful.

    The primary difference between React and Preact is that React uses synthetic events, which are wrapped around the actual events that React has added to make all the events work seamlessly across all browsers.
    Preact has discarded these for their performance and code-size issues.
    It registers event handlers using the browser’s standard addEventListener. Event nomenclature and behavior are identical to those of simple JavaScript/DOM.

    VS Code with Docker container

    Containers are very convenient way to package "standardized" development environment, 
    and to speed up process of configuring dev environment.  
    Just pull and run image from docker hub!

    In particular on Windows this is helpful, since some of dev tools are only available on Linux.
    And Docker containers are based on Linux most of the time.

    With minimum setup the container could be used directly from VS Code,
    looking and working same as "native" OS environment, and more secure, too!

     Developing inside a Container using Visual Studio Code Remote Development

    The Visual Studio Code Dev Containers extension lets you use a container as a full-featured development environment. It allows you to open any folder inside (or mounted into) a container and take advantage of Visual Studio Code's full feature set.

    GoLang + SQLite, without CGo

     Zombie Zen - reaches 1.0

    CGo-less SQLite Go package,, has finally reached version 1.0

    This package provides a low-level Go interface to SQLite 3. It is a fork of that uses, a CGo-free SQLite package. It aims to be a mostly drop-in replacement for

    This package deliberately does not provide a database/sql driver. See David Crawshaw's rationale for an in-depth explanation. If you want to use database/sql with SQLite without CGo, use directly.

    pure Go, no C

    • Full SQLite functionality via, an automatically generated translation of the original C source code of SQLite into Go

    Package sqlite is a cgo-free port of SQLite. Although you could see mattn's driver ( in go.mod file, we import it for tests only.

    SQLite is an in-process implementation of a self-contained, serverless, zero-configuration, transactional SQL database engine.

    Most people use the mattn/go-sqlite3 package to interact with SQLite in Go. This package uses cgo and bundles the SQLite C amalgamation files with the Go source.

    But Go developers often prefer not to use cgo (see for example cgo is not go). I mention this because there happens to be an underrated translation of SQLite's C source code to Go. Since it is a translation of C to Go, you don't need to use cgo to call into it. Some developers find this idea compelling. And this Go translation is an impressive work in and of itself.

    Package sqlite is a cgo-free port of SQLite. Although you could see mattn's driver ( in go.mod file, we import it for tests only.

    SQLite is an in-process implementation of a self-contained, serverless, zero-configuration, transactional SQL database engine.

    Go and SQLite: when database/sql chafes
     2018-04-02, David Crawshaw

    The Go standard library includes database/sql, a generic SQL interface. It does a good job of doing exactly what it says it does, providing a generic interface to various SQL database servers. Sometimes that is what you want. Sometimes it is not.

    Generic and simple usually means lowest-common-denominator. Fancy database features, or even relatively common but not widely used features, like nested transactions, are not well supported. And if your SQL database is conceptually different from the norm, it can get awkward.

    Using SQLite from Go

    • I choose this package because it’s a cgo-free Go implementation of SQLite. Thus, installing it doesn’t require you to have a working C compiler, to start with. What’s interesting is this bit of text from the sqlite website:

      SQLite is a C-language library …

      Thus, is a Go implementation of SQLite.
