# Swift Language Fundamentals
Swift is a modern programming language for Apple platforms (iOS, macOS, etc.) with these key characteristics:
1. Core Features:
- Type inference for automatic type detection
- Optionals for safe handling of missing values
- Closures for flexible function passing
- Memory safety by design
- Built-in error handling

How to keep using adblockers on chrome and chromium

How to keep using adblockers on chrome and chromium

  1. google's manifest v3 has no analouge to the webRequestBlocking API, which is neccesary for (effective) adblockers to work
  2. starting in chrome version 127, the transition to mv3 will start cutting off the use of mv2 extensions alltogether
  3. this will inevitably piss of enterprises when their extensions don't work, so the ExtensionManifestV2Availability key was added and will presumably stay forever after enterprises complain enough

You can use this as a regular user, which will let you keep your mv2 extensions even after they're supposed to stop working

The absurd complexity of server-side rendering

In the olden days, HTML was prepared by the server, and JavaScript was little more than a garnish, considered by some to have a soapy taste.

After a fashion, it was decided that sometimes our HTML is best rendered by JavaScript, running in a user's browser. While some would decry this new-found intimacy, the age of interactivity had begun.

But all was not right in the world. Somewhere along the way, we had slipped. Our pages went uncrawled by Bing, time to first meaningful paint grew faster than npm, and it became clear: something must be done.

And so it was decided that the applications first forged for the browser would also run on the server. We would render our HTML using the same logic on the server and the browser, and reap the advantages of both worlds. In a confusing series of events a name for this approach was agreed upon: Server-side rendering. What could go wrong?

In dark rooms, in hushed tones, we speak of colours.
