Fwdays вединар: Node.js in 2020: Выйди и зайди нормально - Часть 1
Видео: https://youtu.be/GJY2dyE6328?t=480
За последние 5 лет Node.js очень изменился, но знания о платформе у сообщества остались на уровне 2013-2015 годов, все те же подходы, все те же проблемы. Сообщество плохо следит за новыми возможности, а если и узнает про них, то это не влияет на написание ежедневного кода. В Node.js, да и в JavaScript, слабо проникают фундаментальные знания по программной инженерии и архитектуре, параллельному программированию, GRASP, SOLID, GoF, а если и проникают, то не подвергаются адаптации и переосмыслению. Поэтому, среди других языков программирования JavaScript воспринимается, как несерьезный, а Node.js, как платформа для малограмотных людей. Как преодолеть эту тенденцию и как изменить подход к разработке на Node.js в 2020 году, с использованием всех современных возможностей и знаний, а так же, что нужно изменить в ежедневных практиках написания кода, эти и другие вопросы будут освещены в докладе «Node.js в 2020: Выйди и зайди нормально».
Мы закончим обзор новых возможностей Node.js и сложив все это вместе в Node.js Starter Kit (шаблона проекта) от сообщества Metarhia для построения надежных и масштабируемых облачных и кластерных приложений и быстрой разработки API для высоконагруженных и интерактивных систем. Будет опубликован манифест Metaserverless. Мы разберем код, обсудим использование новейших возможностей платформы Node.js и фундаментальных знаний CS для построения грамотной структуры и архитектуры проекта.

Byterun is a Python interpreter written in Python with Ned Batchelder. It's architected to mirror the structure of CPython (and be more readable, too)! Learn how the interpreter is constructed, how ignorant the Python compiler is, and how you use a 1,500 line switch statement every day.
Christian Gill ''Functional programming for the people''OdessaJS Conf
There is a lot of mystery around functional programming. Even though libraries like React and Redux brought some of its concepts to JavaScript developers, there is still a lot more to be discovered and many benefits that we can gain from it.
We'll go through some of the principles and fundamentals of functional programing and how we can leverage them to write composable and declarative JavaScript code.
Learn how Visual Studio 11 powers HTML5 development with new tooling and framework features. We’ll dive into some HTML5 specifics like the drawing capabilities of canvas, the geolocation API, HTML5 local storage and offline web applications.
I'll found many papers and books talking about category theory, but many peoples still don't know how it can help. On this talk I'll help you better understand how math can help us develop a software more composable.

The X-Ray Engine is a game engine, used in the S.T.A.L.K.E.R. game series. Its code was made public in September 16 2014, and since then, STALKER fans continue its development. A large project size, and a huge number of bugs in the games, gives us a wonderful chance to show what PVS-Studio is capable of.
Reactive programming with RxJS - ByteConf 2018Tracy Lee
Reactive programming paradigms are all around us. So why does is it awesome? We'll explore reactive programming in standards, frameworks and libraries and talk about how to think reactively.
Then we'll take a more practical approach and talk about how to utilize reactive programming patterns with an abstraction like RxJS, a domain specific language for reacting to events and how using this abstraction can make your development life much easier in React Native.
Very quick introduction to the language R. It talks about basic data structures, data manipulation steps, plots, control structures etc. Enough material to get you started in R.
JavaScript is becoming more functional nowadays. map and filter - those words mean a lot for modern programming world. Some people think that those are just Array.prototype methods. But Bacon.js also implements map and filter algorithms in their codebase, as well as RxJS. Immutable.js and lazy collections from lodash library do have their own implementations of these algorithms. Transducers is an attempt to describe and implement the essence of these (and lots of other) algorithms, ignoring the context which they are applied to - arrays, lazy collections, event streams or queues/channels.
Conference: JS is Back! fwdays
In addition to blocking CPU-bound tasks, we can use worker_threads to run asynchronous non-blocking domain logic if our main event loop is already overloaded. Now we have perf_hooks API which can be used to create load balancer to spread load in worker pool to provide the most dense event loop utilization. Mentioned machinery can be encapsulated in a simple abstraction with async/await contract to have a solution competing with goroutines in Go for both convenience and efficiency.
Node.js Меньше сложности, больше надежности Holy.js 2021Timur Shemsedinov
If Node.js is your everyday tool, it's almost certain that you use it in the wrong way, Timur will prove that in a very short review, uncover anti-patterns in your daily standard solutions, and show you the way to much better practices. The only thing that creates obstacles in your way to knowledge is your laziness.
Low-code sells great, but in practice, it does not provide the benefits that vendors have claimed. What are the reasons and how can we get an advantage using the Low-code principle? Experience of radical rethinking and use-cases in enterprise applications together with multi-paradigm programming and metaprogramming.

Innovating Inference - Remote Triggering of Large Language Models on HPC Clus...Globus
Large Language Models (LLMs) are currently the center of attention in the tech world, particularly for their potential to advance research. In this presentation, we'll explore a straightforward and effective method for quickly initiating inference runs on supercomputers using the vLLM tool with Globus Compute, specifically on the Polaris system at ALCF. We'll begin by briefly discussing the popularity and applications of LLMs in various fields. Following this, we will introduce the vLLM tool, and explain how it integrates with Globus Compute to efficiently manage LLM operations on Polaris. Attendees will learn the practical aspects of setting up and remotely triggering LLMs from local machines, focusing on ease of use and efficiency. This talk is ideal for researchers and practitioners looking to leverage the power of LLMs in their work, offering a clear guide to harnessing supercomputing resources for quick and effective LLM inference.

Climate Science Flows: Enabling Petabyte-Scale Climate Analysis with the Eart...Globus
The Earth System Grid Federation (ESGF) is a global network of data servers that archives and distributes the planet’s largest collection of Earth system model output for thousands of climate and environmental scientists worldwide. Many of these petabyte-scale data archives are located in proximity to large high-performance computing (HPC) or cloud computing resources, but the primary workflow for data users consists of transferring data, and applying computations on a different system. As a part of the ESGF 2.0 US project (funded by the United States Department of Energy Office of Science), we developed pre-defined data workflows, which can be run on-demand, capable of applying many data reduction and data analysis to the large ESGF data archives, transferring only the resultant analysis (ex. visualizations, smaller data files). In this talk, we will showcase a few of these workflows, highlighting how Globus Flows can be used for petabyte-scale climate analysis.
