Taichi: Best of Both Worlds
Algorithmic Overview
N
by N
grid of point-masses, where adjacent points are linked by springs. The following image, provided by Matthew Fisher, illustrates this structure:
- Gravity
- Internal forces of the springs
- Damping
- Collision with the red ball in the middle
t = 0
. Then, at each step of the simulation, it advances time by a small constant dt
. The program estimates what happens to the system in this small period of time by evaluating the effect of each of the 4 factors above, and updates the position and velocity of each mass point at the end of the timestep. The updated positions of mass points are then used to update the image rendered on the screen.
Getting Started
pip install taichi
.
ti
:
import taichi as ti
ti.init(arch=ti.cuda)
If you don't have a CUDA GPU, Taichi can still interact with your GPU via other graphics APIs, such as ti.metal, ti.vulkan, and ti.opengl. However, Taichi's support for these APIs is not as complete as its CUDA support, so, for now, use the CPU backend: ti.init(arch=ti.cpu)And don't worry, Taichi is blazing fast even if it only runs on the CPU. Having initialized Taichi, we can start declaring the data structures used to describe the mass-spring cloth. We add the following lines of code:
N = 128
x = ti.Vector.field(3, float, (N, N))
v = ti.Vector.field(3, float, (N, N))
Node.js Vs. Python: Pros, Cons, and Use Cases
When choosing a programming language for the backend development, your choice determines how the product will operate, scale, and fulfill user demands.
One of the most common is the dilemma of Node.js vs. Python. The two options are hugely popular and have their pros and cons. We work with both and are here to compare their advantages and disadvantages and help you to decide which one is better for your project.
The Reports of Perl’s Death Have Been Greatly Exaggerated
Look, I get it. You don't like the Perl programming language or have otherwise disregarded it as "dead." (Or perhaps you haven't, in which case please check out my other blog posts!) It has weird noisy syntax, mixing regular expressions, sigils on variable names, various braces and brackets for data structures, and a menagerie of cryptic special variables. It's old: 34 years in December, with a history of (sometimes amateur) developers that have used and abused that syntax to ship code of questionable quality. Maybe you grudgingly accept its utility but think it should die gracefully, maintained only to run legacy applications.
But you know what? Perl's still going. It's had a steady cadence of yearly releases for the past decade, introducing new features and fencing in bad behavior while maintaining an admirable level of backward compatibility. Yes, there was a too-long adventure developing what started as Perl 6, but that language now has its own identity as Raku and even has facilities for mixing Perl with its native code or vice versa.

97 Things Every Java Programmer Should Know with Kevlin Henney [Podcast]
In 2020, Java celebrated its 25th anniversary. Despite being more than 2 and a half decades old, it still remains one of the most popular programming languages in the world, dominating enterprise application development.
In this episode, we’re joined by the co-author of the recently released “97 Things Every Java Programmer Should Know”. He shares with us his experience in collecting the various voices, advice, and even contradicting opinions that make up the book, its relevance in the “low-code, no-code space”, and why some programming languages, like Java, will never die.
Low Code and No-Code Considerations
Low-code and no-code development platforms have been the trending IT topic for some time now. Experts in this field speculate as to how they could change the future of the industry. Some publications predict the gradual decline of traditional IT, as low-code and no-code products continue to reshape the very approach to solutions development. But, before we get into a discussion on the future of low-code and no-code, let’s define what these terms actually mean.
What Is Low-Code/No-Code?
Low-code and no-code tools help scale and maximize software delivery. The grid below explains, defines, and differentiates low-code vs. no-code tools.
Top Automation Programming Languages of 2021
Introduction
In today’s highly competitive world, software development and automation play a significant role in creating robust software applications for businesses. Additionally, emerging technologies like artificial intelligence and blockchain have given a competitive edge to enterprises. For gaining maximum benefits out of automation testing, testers require hands-on experience in a minimum of one automation programming language. There are numerous programming languages available today, with new ones continuously emerging. No matter which phase you are in, whether starting with automation testing or being an experienced tester planning to learn a new programming language, deciding which language to choose is very critical.
Which Automation Programming Language Is the Best for Testing?
The following list is prepared after considering metrics like recent trends, language popularity, career prospects, open-source projects, and more. As per TIOBE Index 2021 and IEEE Spectrum Magazine, Java, C, and Python are the top three automation programming languages on the list. Following are some of the most preferred languages on the whole entire list.
Perl Can Do That Now!
Last week saw the release of Perl 5.34.0 (you can get it here), and with it comes a year's worth of new features, performance enhancements, bug fixes, and other improvements. It seems like a good time to highlight some of my favorite changes over the past decade and a half, especially for those with more dated knowledge of Perl. You can always click on the headers below for the full releases' perldelta
pages.
Perl 5.10 (2007)
This was a big release, coming as it did over five years after the previous major 5.8 release. Not that Perl developers were idle—but it wouldn't be until version 5.14 that the language would adopt a steady yearly release cadence.

A bit of background about me before we begin our exploration of a new programming language.
SKP’s Java/Java EE Gotchas: Clash of the Titans, C++ vs. Java!
TIME JavaScript vs Other Popular Languages of the 21st CenturyThe trends in the programming industry have changed so much in the past decade. One such evolution was seen in the web development industry. In the earlier days, web development originally just dealt with the development of web pages and websites for the intranet and internet. As time has passed, it has become more focused on creating complex and detailed web, mobile, and desktop applications. The Best Programming Languages for Mobile App DevelopmentDo you know how to code? Have you been thinking about learning to code for various mobile apps development? Fortran and the ”Old Guard” of Programming Languages“You’re using Fortran? Seriously? Listen, 1982 called, and they want their leg warmers back.” - Every developer since 2008 Every once in a while, I run across someone who’s working with Fortran, or COBOL, or Ada, or (if I’m lucky) LISP. These are the old guard of programming languages, and with the exception of LISP*, that is not said with a lot of aspiration. For most developers, jobs that list “3+ years of Fortran” are laughed at (at best). Top 11 Programming Languages for Blockchain DevelopmentBlockchain technology is a very fast, secure, and decentralized technology that is currently causing a paradigm shift in many industries today. The development of this technology has brought about improvements in many industries even though it has many skeptics and is not a mainframe technology yet. To develop this technology, the following programming languages are used. C++C++ is an old programming language developed during the 70s and 80s. It is a high speed, compiled, object-oriented, and strongly static programming language. This language is highly efficient. As stated in many professional writing services, it was created as a C language extension but is a more difficult language to learn and more complicated. So, it really is not for beginners. Top 6 New Programming Languages Born in the Last DecadeWhen it comes to programming languages, progress does not standstill. While the most influential ones like Python, C, Java were created a long time ago, new valuable coding languages appear all the time. In many use cases, it is the new programming language that is driving innovations and helps build truly amazing software. Let’s look at the most promising ones that were born in the last decade. What Is Rust Programming Language?Rust is a system programming language, created by Mozilla, which was announced in 2010. Rust is positioned as an incredibly fast language, that prevents memory violations and guarantees thread safety. Rust is syntactically similar to C ++ and in terms of speed, it can be compared to C or C ++. This means that the applications written in Rust can be just as fast as those written in C or C ++ and faster than those written in other dynamic languages. Top 6 Programming Languages for Mobile App DevelopmentMobile application development industry in the last five years has multiplied in leaps and bounds, changing the way businesses function worldwide. With enterprises aligning mobile apps to their productivity in recent times, and with the rapid innovation in mobile devices across platforms, it calls for mobile app developers to write several versions of an application for many different platforms using a single language and many pieces of reusable code. Are you game for that? Once you intend to realize your mobile app idea, it's time to validate it, understand the target market, and narrow down the platform on which you ideally would like to build your mobile application. As soon as that is decided, it’s time to select a programming language, keeping in mind your business strategy to make either native, hybrid, or cross-platform apps. Most Popular Programming Languages in 2020With a forecast for 2018 and 2020. It was forecasted that 20 billion apps would be downloaded in 2020 in the UK. According to the survey reports, the number of downloaded mobile applications is increasing constantly. In the contemporary era, now customers prefer mobile applications to get information about the service or product; however, mobile applications have turned as a success key to stay ahead in the market competition. The high usage of mobile applications has raised to the demand of the mobile application development service with the latest integrated trends such as blockchain and the Internet of things. Selecting a Programming Language for Selenium Automation TestingAs people are shifting to automation from manual testing, they prefer to go with the best-suited testing framework for them. When we talk about a popular automation testing framework, most people immediately think about Selenium. Selenium is one of the most reliable, portable software testing frameworks for web applications. It comes with one test domain-specific programming language Selenese for writing automation scripts, but it also supports other programming languages like Java, Python, Ruby, Javascript, PHP, and C#, which makes it a good choice. While moving to automation testing with Selenium, everyone who tests has to face a question: Which programming language should you use for writing test automation suits? |
