A Visual Guide to Directory Structures Where do you put your files? How does Laravel know? These are a few questions that I normally get from individuals just starting out with Laravel, or really any other framework. Laravel creates a folder structure for you and it expects certain files to appear in specific places. If they’re not there, Laravel will not know what to do. It expects your controllers to be in the Http folder, it expects your models to be in the Models folder, etc. If you’re not familiar with those concepts yet, don’t worry, we’ll cover each of them

Get Ready to Docker Closing down the PHP project today felt a little sad. It’s a series that I’ve been working on for quite some time now and finally felt like I’ve exhausted the subject. I’ll probably continue with some more advanced topics since I don’t want it to end. As I write that, I feel a little better about it now. Let’s continue with my absolute favorite framework, Laravel. We briefly looked at the installation process in the previous article, and to be honest, it’s about as simple as it gets. There are a few different ways to install
Empower Your Web Development Journey Laravel is a PHP framework that gives you the tools you need to create sophisticated web applications, but it also allows you to focus on the application logic. It’s built with modern language features and supports multiple databases out of the box. What is Laravel? Laravel is a PHP framework built on the principle of convention over configuration. It’s a fully open-source, community-driven project that focuses on simplicity and elegance in building web applications. Laravel was created by Taylor Otwell in 2010 and has become one of the most popular PHP frameworks today. Laravel is built on top of the Symfony component
It’s Kind of Spontaneous. First, we cannot force garbage collection to run (System.gc()). Sometimes it will but it’s unpredictable. In Java, garbage collection runs automatically in the background, managed by the Java Virtual Machine (JVM). The exact timing of its execution isn’t deterministic and depends on various factors, including: Heap Memory Usage: Garbage collection typically occurs when the JVM detects that the heap memory is running low and needs to free up space. JVM Implementation: Different JVM implementations (like HotSpot, OpenJ9, etc.) have their own algorithms and heuristics for deciding when to run the garbage collector. Garbage Collection Algorithm: The
Download Images with Java Whenever your company gets new software, you’re bound to work overtime as a programmer. The staff figured out that you can load images into the POS software and the sales staff can see the image for each part. Hooray…for them. “This shouldn’t be a problem for you, right Dino? We absolutely need this to work. This would improve sales drastically!” …Right. So I contact the company and ask them if there’s any way to import the images in bulk. They tell me that there is. Apparently you can upload an entire folder into the system. As
Programming Language Concepts Let’s finish this series off right: with another 141 questions. I think 781 questions are a good starting point in your Computer Science exploration. Check out the links at the bottom of the page for the previous 640 questions. 641. True or False? Pointers in C can point to any variable. – True 642. How do you get the address of a variable in C? – with the ampersand symbol (&) 643. If the pointer is pointing to an array, what are the 3 forms of pointer arithmetic supported in C and C++? – Adding an integer
Programming Language Concepts I think it’s time to start moving into some relatively modern questions. 547. What is an associative array? – An unordered collection of data elements that are indexed by keys. 548. Each element of an associative array is a pair consisting of a _______ and a _______. – key and a value 549. True or False? Java supports associative arrays? – True. As a matter of fact, Perl, Python, Ruby, C++, C# and F# do too. 550. What are associative arrays called in Perl? – hashes 551. Why are associative arrays in Perl called hashes? – Because

What are the 3 approaches to implementing programming languages? – Compilation, Pure Interpretation and Hybrid Implementation 325. What is the job of the syntax analyzer? – Check the syntax of the program and create a parse tree. 326. What are the syntax analyzers based on? – Formal description of
