spec VS ImageOptim

You may define that Ruby is "CRuby" (MRI), the full-fledged implementation of the Ruby programming language specification (https://github.com/ruby/spec/).

Testing: Interestingly, most of the work was figuring out how to test the library reliably. Grizzly-rb is proudly tested against the ruby/spec repository using Mspec and Rubocop. Special thank you to the person recommending Rubocop in a previous post.  The tests cover Enumerable, Array, Enumerator and Enumerator::Lazy classes.

Ruby interpreter is a complex program, so it naturally has bugs, and Ruby interpreter developers are taking various countermeasures against them. For example, we write tests and check them in CI environment (This is the result of daily maintenance of the test environment, such as RubyCI, chkbuild, ruby/spec: The Ruby Spec Suite aka ruby/spec and machines).

I can't find the link to the official announcement, but many years ago they published an official ISO for Ruby, however at the time the ISO was based off of 1.8.7 syntax/semantics. Other than that, you have the RubySpec project which is a series of tests that validate how Ruby should work.

Java could have been a good example, but Sun had a rather strict validation process for calling something Java.

Furthermore, there are big difference in philosophy with C:

1. IB and UB are not considered normal parts of specifications, meaning there's way less opportunity for originality in the interpretation of the specifications

2. there tends to be an ur-implementation, and notable divergences from that tends to be interpreted as either a bug in the other implementation(s) or a lack of specification to be resolved between all implementations

Rust only has UB in unsafe (AFAIK), which greatly limits implementation flexibility in terms of observable behaviour; and the reference implementation would very much be considered the reference implementation, so I expect e.g. rust-gcc will be sticking close to the reference implementation and behavioural divergence will either be fixed to match, or will lead to more precise specification and both implementations converging.

Probably eventually with, if not a Sun-style validation suite, a Ruby-style Spec Suite (https://github.com/ruby/spec).

Ruby: https://github.com/ruby/spec Yes, it is not a word document, but it is a spec nonetheless. It is an authoritative source. TypeScript has nothing like this; no, unit tests aren't the same.

Opal is simply a Ruby to JavaScript compiler. While it may be someday possible to run Rails on it, as you can run Rails on JRuby, the primary focus of this project is to allow you to write frontend code in Ruby and possibly share some code between your frontend and backend. It's possible to compile entire Ruby libraries to JavaScript (with little changes needed due to some caveats). Opal supports a Ruby 3.0 level of features (regardless of your backend Ruby version), often surpassing MRuby in terms of compatibility. It is being actively tested for regressions against Ruby Spec and is self-hosting, ie. can compile itself (see: TryRuby).

Compressing images: This technique reduces image size without compromising quality. You can achieve this using various image compression tools like TinyPNG or ImageOptim. These tools are specifically designed to manage multiple image formats and compression methods. They help reduce image files, resulting in less data transfer from the server to the user's device. It is advisable to compress images before uploading them to the web server.

ImageOptim: ImageOptim is a free and open-source tool that can be used to compress JPEG, PNG, and GIF images.

ImageOptim - file resizing and optimising images, even on the command line (free)

ImageOptim - Price: Free Image optimizer for Mac that allows you to reduce the file size of your images without losing quality, and strip the metadata.

If you're on a Mac, use ImageOptim to optimize your images: https://imageoptim.com/mac If you're on Windows, I imagine there's a similar app

Bonus points: before you re-import them drop the exports folder into imageoptimfor the most efficient lossless compression imaginable.

ImageOptim — shrink those file sizes!
