WebAssembly will be the next big thing in IT and in Web Developement world. But web developlemnt is a JavaScript doman. What it has to do with .NET and C#? Well Microsoft is experimenting with Blazor and other companies and community members with different aproaches like Ooui and Uno. All of that sits on top of Mono! Long storie short - WebAssembly in a nutshell

  6. 6. Hypertext, HTML, HTTP Text displayed on a electronic devices with references (hyperlinks) to other text that the reader can immediately access. Hypertext documents are interconnected by hyperlinks, which are activated by a mouseClick, keypress set or by touching the screen. „Hypertext" is also used to describe tables, images, and other content formats with integrated hyperlinks. Hypertext is one of the key underlying concepts of the WorldWide Web, where Web pages are often written in the Hypertext Markup Language (HTML). As implemented on the Web, hypertext enables the easy-to-use publication of information over the Internet. The HypertextTransfer Protocol (HTTP) is an application protocol for distributed, collaborative, and hypermedia information systems. HTTP is the protocol to exchange or transfer hypertext.

This allows applications and libraries originally designed to run as standard executables to be integrated into client side web applications. asm.js can be compiled by browsers ahead of time meaning that the compiled programs can run much faster than those traditionally written in JavaScript.

I will be pleased to be able to improve my presentation thanks to your comments, so please fill in the questionnaire or contact me via email. Działanie pociąga za sobą koszty i ryzyko, ale o wiele mniejsze niż te, które wiążą się z wygodną bezczynnością

Editor's Notes

  • dziekuje ze tak licznie przybyliscie na moja prezentacje i mozliwosc podzielenia się z wami odrobina wiedzy jaka zebrałam …. Nie wiem co dodac
    Chciałabym wam przybliżyć choć trochę temat web assembly –
  • Q
    Kto jest web developerem
    Kto xam devem
    Kto desktop WPF UWP

    QR ze szczegolami

    skąd się wzięło, dlaczego się pojawilo
    co to w ogóle jest
    Jak można napisac
    Troche powiem o tym czego jeszcze brakuje i co gogle planuje dalej
    Co do tego wszystkiego ma xamarin
    I opowiem o kilku frameworkach które kręcą się wokół tego tematu
  • O mnie…
    Funboy MS
    Glownie tego co sie dzieje dookola ms – grupy spolecznosci ludzie

    Te tapety sa wyrazem ms wychodzacego do programistow

    Strasznie mi sie podobalo to co ms robil do tej pory dla devow,
    proba ocieplenia wizerunku
  • Ale zacznijmy od malego skosu w histori
  • August 6, 1991
    Tim Berners-Lee
    CERN (on NeXT computer)

    Hypertext linki I zawartosc

  • Tylko zawartosc I linki
    statycznie
  • Pojawily sie obrazki ale nadal statycznie

    Wyszukiwarki wyszukiwaly zawartosc
  • 10 days prototype as Java like language JavaScript enables interactive web pages and thus is an essential part of web applications.
    Dowcipkowal ze zrobil to na kacu
  • JS jezyk zrozumialy dla ludzi – latwy do zrozumienia
    Dynamiczne typy
    Ale czytelna dla developera – trade off
    ByteCode is run in interpretor
  • Nie zaprojektowana aby była szybka
    Jest wolniej ale jest latwo uzywac wiec wszyscy się na to godza.

    Poprostu parsowanie I wykonanie. powolne
  • 2007
    W miedzyczasie potrzeba innych jezykow,
    Potrzeba potezniejszych narzedzi, wiekszych mozliwosci
    Ale ogromne dziury w zabezpieczeniach I podatnosc na ataki
  • 2009 node.js and server side JS
    Coraz lepsze silniki.
    V8 Chrom,
    SpiderMonkey – Firefox
    Chakra – Edge
    Nitro, SquirrelFish, JavaScriptCore -Safari
  • Optymalizacja w trakcie uruchomienia
    OdynMonkey uzywal kompilacji AOT in runtime kbum
  • Ten wykres moze sie roznic z program na program.
    Ale jest ten etap reorganizacji kodu I compilacji na zasadzie przygotowania do uzycia
  • Obecnie JS jest wszedzie.
    Jest go strasznie duzo
    Niski prog wejscia, obietnica zycia w swiecie IT
    Ogromne zapotrzebowanie
    Ogromne mozliwosci
    Najbardziej uniwersalna platforma – WEB
    JS jest jezykiem internetu
    Ale nie jest jezykiem Assembly – jest human readable language
  • Compile target for web (bytecode)
    Uses linear memory

    WebAssembly (abbreviated Wasm) is a binary instruction format for a stack-based virtual machine. Wasm is designed as a portable target for compilation of high-level languages like C/C++/Rust, enabling deployment on the web for client and server applications.
  • Rust
    C
    C++
    GO
    Kotlin
    Python
    Haskell
    TypeScript

    Not designed to replaced JS
    compilator
    https://en.wikipedia.org/wiki/Emscripten
    Emscripten is a source-to-source compiler that runs as a back end to the LLVM compiler and produces a subset of JavaScript known as asm.js.[3] It can also produce WebAssembly.[4] This allows applications and libraries originally designed to run as standard executables to be integrated into client side web applications. asm.js can be compiled by browsers ahead of time meaning that the compiled programs can run much faster than those traditionally written in JavaScript.
