These days a lot is being said about how AI will change everything in our lives for the better, but have you ever wondered what exactly goes on in an artificial brain?
I did, and thought that I’d share a step-by-step tutorial on how to build a human-like chess engine. Why is this important to you? Well, think a little about it.
Chess has traditionally been a challenging problem to be addressed. …
Hi everybody, how have you been?
Today’s post is the continuation of the previous one, A WordPress Setup With Docker, PHP 7.4, Apache 2.4 and MySQL 8 on Ubuntu 20.04 LTS, where we looked at a step-by-step approach to setting up a WordPress 5 site locally.
It turns out to be the case that nowadays most professional web sites use HTTPS in order to protect users’ connections over the Internet, as well as to look SEO friendly to Google’s eyes, and WordPress is no exception.
In fact, well, if you’re a WordPress developer, as a rule of thumb you should…
Are you a web developer working on another WordPress site? If so, you may want to run a site locally and safely on your laptop to play around with a theme or plugin first, or you want to experiment with this or that cool feature with no fears on breaking the live site.
Today’s post is especially helpful in 2020 and 2021 with so many radical, disruptive changes taking place in the WordPress community mainly introduced by the development of Gutenberg, the new content editor for WordPress 5.0.
Here we go one more time with another brief how-to guide on Ethereum smart contracts with Solidity.
In the previous post entitled The Git Way for a Smart Contract to Receive Ether we looked at how to write a contract that would receive ether, and today we’re just querying its balance through a Node.js app.
Once again, let’s do it step by step the Git way!
Please sit back and make yourself comfortable, go take a cup of tea on this occasion and browse the commit log at programarivm/solidity-contract-balance.
Hey dapp developers, how are things going? Today I am excited to show you how to deploy another Solidity smart contract into Ropsten. This simple contract will be capable of only receiving ether so its balance can be queried at any moment.
Let’s do it step by step, the Git way!
Please visit programarivm/solidity-receive-ether and sit back, go take a cup of coffee while browsing the commit log of the repo.
Disclaimer: This tutorial is aimed to intermediate dapp learners who already know a few basics about Truffle and Solidity, and want to know more.
Lately I’ve been wrapping my head around implementing a basic AI model that would allow to play chess with the help of a powerful, relational database running under the hood.
If you’ve heard before about the PGN format then you’ll probably know it stands for Portable Game Notation, which is a standard to represent chess games with text files.
Here is what the Portable Game Notation Specification and Implementation Guide by Steven J. Edwards says about it:
The intent of the definition and propagation of PGN is to facilitate the sharing of public domain chess game data among chessplayers (both…
In the previous post entitled A Simple Laravel ACL Example we wrote a simple custom access control list (ACL) and learned that the steps we went through also apply to plain PHP apps as well as to any other PHP framework.
Today we are taking a step further by letting our app authorize validation logic in a decoupled way with the help of Laravel’s form requests.
Since authorization stuff needs to be performed by access control rules, we’re now taking full advantage of our ACL while following one of the five SOLID principles of object oriented design: the Open-Closed…
Implementing an ACL (access control list) in your Laravel application is actually a snap.
Let me share a simple solution which basically consists in writing a middleware only to match the URL of the incoming request against the permissions stored into the database.
In the present article we are not using any third party Laravel package. This simple ACL idea is intended to those who are not big fans of installing unnecessary external dependencies in their projects.
Are you a full-stack PHP developer? Chances are that you might want to easily override an environment variable through the command-line interface.
Let’s say you are writing a bash script to automate a certain process: your Docker containers must be rebuilt, and the app’s
REDIS_HOST variables must be updated accordingly.
On such scenario, PHP frameworks like Laravel can be easily extended in order to accomplish our goal, specifically the FlexEnv package can help like this:
$ php artisan env:set NEW_KEY "your key's value"
Hey everybody, Jordi here, and today I am sharing some thoughts on my first real-world — as opposed to “Hello world” — React app.
It seems there aren’t too many tutorials out there on how to build complex React applications with Flux. Well, the RealWorld example apps can help — even though I wasn’t able to find any Flux implementation example.
So I decided to write an SPA application called Meerkat, this funny mammal resembling a small dog, much like Timon in the Lion King.
The repo is available on GitHub, and basically the app allows users to review and…
All things web and more.
