lazysizes is a fast (jank-free), SEO-friendly and self-initializing lazyloader
lazysizes is a fast (jank-free), SEO-friendly and self-initializing lazyloader for images (including responsive images picture/srcset), iframes, scripts/widgets and much more. It also prioritizes resources by differentiating between crucial in view and near view elements to make perceived performance even faster.

It may become also your number one tool to integrate responsive images. It can automatically calculate the sizes attribute for your responsive images, it allows you to share media queries for your media attributes with your CSS, helping to separate layout (CSS) from content/structure (HTML) and it makes integrating responsive images into any environment really simple. It also includes a set of optional plugins to further extend its functionality.

Tuning MetaOCaml Programs for High Performance
Tobias Langhammer

“The domain of high-performance computing is still dominated by manual optimizations of programs written in C or Fortran. The reason why high-level languages failed to gain ground is the execution overhead entailed by the potential abstractions introduced.

This thesis proposes MetaOCaml for enriching the domain of high-performance computing by multi-staged programming. MetaOCaml extends the OCaml language by three new constructs in order to provide run-time code generation. By tagging OCaml code fragments with a pair of special brackets, they become abstract data objects of the program enclosing them. This program can create and combine code objects at run time as well as execute them in its environment by the application of a single operator. This allows the easy construction of speed-optimized code. Furthermore, like OCaml, MetaOCaml is a language with static types. Though code objects are generated and executed at run time, its type system guarantees the type correctness of run-time generated code at the time the program is compiled.

This thesis presents important speed-related issues, like speed-aware coding style, offshoring or interfacing to C. Three case studies demonstrate the applicability of these in realistic contexts and discuss the impact in terms of execution speedup.

Focusing on numerical applications, the first case study examines iterative and recursive implementations of matrix multiplications, comparing low-level C optimizations with high-level implementations using MetaOCaml. Hybrid implementations show how to combine the optimization opportunities of both approaches.

A second case study demonstrates how MetaOCaml can be used for the implementation of a domain-specific language. The presented compiler combines a simplifier working on the abstract syntax and a code generation function using MetaOCaml syntax. As the code generator can be constructed by adding MetaOCaml constructs to the code of an interpreter, the effort of this implementation is marginal compared to the speedups attained.

Finally, the case study of a parallel Karatsuba polynomial multiplication presents an embedded specification language for a static parallel computation structure. The implementation of this language gives an example of how specialized code can be generated with MetaOCaml by using information about the parallel run-time environment. Also, it demonstrates a clean approach to separate the concerns of the application implementer and the parallel engineer.

Benchmarks for all presented implementations confirm that the execution time can be reduced significantly by high-level optimizations. Some MetaOCaml programs even run as fast as respective C implementations. Furthermore, in situations where optimizations in pure MetaOCaml are limited, computation hotspots can be explicitly or implicitly exported to C. This combination of high-level and low-level techniques allows optimizations which cannot be obtained in pure C without enormous effort.”
