Flow-based Programming In computer programming, Flow-Based Programming (FBP) is a programming paradigm, discovered/invented by J. Paul Rodker Morrison in the late '60s, that uses a "data processing factory" metaphor for designing and building applications. FBP defines applications as networks of "black box" processes, which communicate via data chunks (called Information Packets) travelling across predefined connections (think "conveyor belts"), where the connections are specified externally to the processes. 7 JavaScript Utility Functions to Improve Your Efficiency Different browsers have different navigator.useragent. We can detect browser types by checking this value. Example: There was a 'chrome' string on the result. There was a 'firefox' string on the result.
JavaScript Design Patterns in Action — Soshace By Shadid Haque Following Unfollow Follow 21,544January 2, 2020 Following Unfollow Follow JavaScript Design Patterns in Action In this article, we are going to explore all the popular design patterns used in JavaScript. We will discuss how to implement these patterns and why we need to build them. We will discuss:
Make GNU Make is a tool which controls the generation of executables and other non-source files of a program from the program's source files. Make gets its knowledge of how to build your program from a file called the makefile, which lists each of the non-source files and how to compute it from other files. When you write a program, you should write a makefile for it, so that it is possible to use Make to build and install the program. Capabilities of Make Make enables the end user to build and install your package without knowing the details of how that is done -- because these details are recorded in the makefile that you supply. Make figures out automatically which files it needs to update, based on which source files have changed.
levelup.gitconnected Like many programming languages, JavaScript has its flaws and quirks. Built-in functions or syntax you think should be there just isn’t. Output from even the most basic input can border on insanity (what’s true + true ?). Even basic things like loops behave differently than one might expect. Though JavaScript behaves strangely from time to time, it is still one of the most widely used languages today. Bash Bash is the GNU Project's shell. Bash is the Bourne Again SHell. Bash is an sh-compatible shell that incorporates useful features from the Korn shell (ksh) and C shell (csh). It is intended to conform to the IEEE POSIX P1003.2/ISO 9945.2 Shell and Tools standard. It offers functional improvements over sh for both programming and interactive use. In addition, most sh scripts can be run by Bash without modification.
levelup.gitconnected Null and Undefined are both data types in JavaScript. Undefined is a variable that has been declared but not assigned a value. Null as an assignment value. So you can assign the value null to any variable which basically means it’s blank. So by not declaring a value to a variable, JavaScript automatically assigns the value to undefined. However, when you assign null to a variable, you are declaring that this value is explicitly empty. Soft Actor Critic—Deep Reinforcement Learning with Real-World Robots – The Berkeley Artificial Intelligence Research Blog We are announcing the release of our state-of-the-art off-policy model-free reinforcement learning algorithm, soft actor-critic (SAC). This algorithm has been developed jointly at UC Berkeley and Google Brain, and we have been using it internally for our robotics experiment. Soft actor-critic is, to our knowledge, one of the most efficient model-free algorithms available today, making it especially well-suited for real-world robotic learning.
Understanding Closures in JavaScript A closure is a function that has access to its outer function scope even after the outer function has returned. This means a closure can remember and access variables and arguments of its outer function even after the function has finished. Before we dive into closures, let’s first understand the lexical scope. What is a Lexical Scope? A lexical scope or static scope in JavaScript refers to the accessibility of the variables, functions, and objects based on their physical location in the source code. Populating MS Word Templates with Python Introduction In a previous post, I covered one approach for generating documents using HTML templates to create a PDF. While PDF is great, the world still relies on Microsoft Word for document creation. In reality, it will be much simpler for a business user to create the desired template that supports all the custom formatting they need in Word versus trying to use HTML+CSS. Fortunately, there is a a package that supports doing a MS Word mailmerge purely within python. This approach has the advantage of running on any system - even if Word is not installed.
Private Members in JavaScript Douglas Crockford www.crockford.com JavaScript is the world's most misunderstood programming language. Some believe that it lacks the property of information hiding because objects cannot have private instance variables and methods. But this is a misunderstanding. JavaScript objects can have private members. Here's how. 10 Practical JavaScript Tricks - DEV I'm always on the lookout for new ways to be more efficient. And JavaScript is always full of pleasant surprises. 1. Transform the arguments object into an array.
Five OpenAI Five plays 180 years worth of games against itself every day, learning via self-play. It trains using a scaled-up version of Proximal Policy Optimization running on 256 GPUs and 128,000 CPU cores — a larger-scale version of the system we built to play the much-simpler solo variant of the game last year. Using a separate LSTM for each hero and no human data, it learns recognizable strategies. This indicates that reinforcement learning can yield long-term planning with large but achievable scale — without fundamental advances, contrary to our own expectations upon starting the project. To benchmark our progress, we’ll host a match versus top players on July 28th. Follow us on Twitch to view the live broadcast, or request an invite to attend in person!
