Differences Between Laravel and Yii

Actualités, Méthodes et organisation des process IT

Ask any seasoned web app developer about their choice of programming language, and they are sure to mention PHP. PHP is a widely-used general-purpose scripting language that is especially suited for Web development and can be embedded into HTML. As per Builtwith, 3,090,319 live websites are still using PHP. However, when it comes to developing massive projects without lag or stability issues, developers tend to use frameworks, and PHP has two remarkable frameworks: 1) Laravel and 2) Yii. Both frameworks have a lot of followers in terms of full-grown communities globally, and there may be questions arising about which to choose.

What Are Laravel and Yii?

Laravel is a simple PHP framework frequently used for web-based or web application development initially created as a better alternative to Codeigniter. It is known for MVC Support, articulated ORM systems, reliability, modularity, and uncomplicated coding rules. Some of the key features of Laravel Framework are:

Old Habits Die Hard, But Getting New Ones is Essential. Tips on Getting the Most Out of TypeScript

Actualités, Méthodes et organisation des process IT

In web development, no one is surprised when a new framework or library enters the stage. Implementing complex functionalities and creating UI elements from scratch only using the powers of a specific programming language is not always the most optimal way. Instead, developers either rely on the existing frameworks or create their own for internal use. In the case of programming languages, the situation is a little more complicated.

A fairly large number of coders are unhappy with the limitations of the programming language that they use every day. Therefore, from time to time, we can hear about the new programming language release. The question is, will the development community adopt it as a replacement for well-established technologies? As an example, we can take a look at Dart. It was initially released in 2011 but remained quite unpopular until the Flutter framework was launched in 2017.

A Beginner’s Guide to High-Performance Computing in Python

Actualités, Méthodes et organisation des process IT

Ever since the Python programming language was born, its core philosophy has always been to maximize the readability and simplicity of code. In fact, the reach for readability and simplicity is so deep within Python’s root that, if you type import this in a Python console, it will recite a little poem:

Beautiful is better than ugly. Explicit is better than implicit. Simple is better than complex. The complex is better than complicated. The flat is better than nested. Sparse is better than dense. Readability counts…

Simple is better than complex. Readability counts. No doubt, Python has indeed been quite successful at achieving these goals: it is by far the most friendly language to learn, and an average Python program is often 5 to 10 times shorter than equivalent C++ code. Unfortunately, there is a catch: Python’s simplicity comes at the cost of reduced performance. In fact, it is almost never surprising for a Python program to be 10 to 100 times slower than its C++ counterpart. It thus appears that there is a perpetual trade-off between speed and simplicity, and no programming language shall ever possess both.

But, don’t you worry, all hope is not lost.

Taichi: Best of Both Worlds

The Taichi Programming Language is an attempt to extend the Python programming language with constructs that enable general-purpose, high-performance computing. It is seamlessly embedded in Python, yet can summon every ounce of computing power in a machine — the multi-core CPU, and more importantly, the GPU.

We’ll show an example program written using taichi. The program uses the GPU to run a real-time physical simulation of a piece of cloth falling onto a sphere and simultaneously renders the result.

Writing a real-time GPU physics simulator is rarely an easy task, but the Taichi source code behind this program is surprisingly simple. The remainder of this article will walk you through the entire implementation, so you can get a taste of the functionalities that taichi provides, and just how powerful and friendly they are.

Before we begin, take a guess of how many lines of code this program consists of. You will find the answer at the end of the article.

Algorithmic Overview

Our program will model the piece of cloth as a mass-spring system. More specifically, we will represent the piece of cloth as an N by N grid of point-masses, where adjacent points are linked by springs. The following image, provided by Matthew Fisher, illustrates this structure:

The motion of this mass-spring system is affected by 4 factors:

Gravity
Internal forces of the springs
Damping
Collision with the red ball in the middle

For the simplicity of this blog, we ignore the self-collisions of the cloth. Our program begins at the time 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

Although Taichi is a programming language in its own right, it exists in the form of a Python package and can be installed by simply running pip install taichi.

To start using Taichi in a python program, import it under the alias ti:

import taichi as ti

The performance of a Taichi program is maximized if your machine has a CUDA-enabled Nvidia GPU. If this is the case, add the following line of code after the import: 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:

Python

 N = 128 x = ti.Vector.field(3, float, (N, N)) v = ti.Vector.field(3, float, (N, N))

8 Reasons Your Site Is Slow + How To Fix Them

Actualités, Actualités

1, 2, 3 – That’s exactly how long it takes you to start losing visitors if you have a slow-loading website.

Hold on! Surely, the only thing that matters to users is that your website works flawlessly and looks great… right? Wrong!

The fact of the matter is that we’ve all become accustomed to instant access to information and content. The average internet user today places a lot of value on speed, and the bar is continually being raised.

If you are like most people, you probably feel an immediate sense of dread at the thought of optimizing your website. Where do you start? How can you make the most impactful improvements? What makes your website slow in the first place?

Have no fear, as we’ll be answering all of your questions below as well as putting you on your way to a website that loads with blazing speed.

Why Should You Be Worried About A Slow-Loading Website?

Good question!

As many as 53% of visitors abandon a site that takes more than 3 seconds to load. Even worse, 1 in 3 shoppers will leave a website if it takes longer than 5 seconds to load.

So, performance plays a huge role in the user experience of your website and whether your visitors will stay on your website or be converted into customers.

For some time, Google has been keenly aware of this fact. As a search engine, Google knows that it’s counterproductive to recommend content to users if they won’t stick around to consume it.

That’s why they’ve continually been increasing the role performance plays when ranking websites for their SERPs (search engine results pages).

In recent years, Google has introduced core web vitals. These are metrics they hope will help quantify how performance affects the user experience. In general, they measure how fast, stable, and interactive a page is while loading. This will be more important than ever after Google announced its Page Experience update, which started its global rollout in June 2021.

As you may know, ranking highly for Google is vital for your website’s visibility. For one, 68% of online experiences begin with a search engine, of which Google has a 92.7% market share. Even if you manage to land on the coveted first page of Google, the first five results get over 70% of all clicks (28% to the first result alone).

So, to recap why a fast loading website is so desirable:

It directly affects your ability to keep, satisfy, and even convert visitors to your website.
It impacts your search engine rankings which impacts your “findability” and organic traffic.

8 Reasons Your Site Is Slow + How to Fix Them

O.K., so now that we’re all on the same page regarding the importance of your website performance, let’s look at common issues slowing down your website + how to fix them.

1. You’re Using A Sub-Par Hosting Service

As the party responsible for making your website available to the outside world, your hosting service can be a make-or-break factor. Not only should you pick a host that has a good track record when it comes to uptime a performance, but also one that’s suitable according to your needs.

Even if you take all the steps below to optimize your website’s performance, it may still load slowly if traffic to your website is overwhelming your available bandwidth or your host’s server capacity. If that happens, some users may experience extremely slow loading times, broken features, or even complete unavailability.

For most personal, blog, or local/small business sites, a respectable hosting provider like Bluehost or GoDaddy should be good enough. However, if you plan on running any type of large-scale, high-traffic webstore, business portal, or other type of website, you’ll want premium hosting, such as WPEngine (for WordPress), VPS hosting, or even a dedicated server.

2. You’re Not Optimizing Your Media Assets

As you probably know, media like images and videos take up significantly more space than most other types of content, such as text, code, stylesheets, or other static files. Even a single image has the potential of consisting of more data than dozens of website pages containing nothing but the underlying HTML and text.

In a Speed Essentials presentation, the Google team identified images as the largest contributor to page weight. In fact, they have the potential to consume a website’s entire performance budget if left unoptimized. Images can also directly impact all three of Google’s core web vitals – key metrics Google uses to measure the performance of a website.

However, the use of images and video is likely to continue growing, heightening the importance of finding a sustainable solution. According to HTTPArchive, images have increased by 19.3% on desktop and 42.7% on mobile.

For now and the foreseeable future, optimizing your images carries the greatest potential for improving performance.

The problem is that optimizing image assets requires multiple steps. Most importantly:

Using the appropriate next-gen formats which can differ depending on the user’s device, OS, or browser.
Appropriately compressing the size and quality of images to reduce payload without affecting visual quality too badly.
Using the optimal display size and density based on the accessing device to reduce payloads further.
Using lazy loading to only load images as needed.

As you can see, manually going through these steps for every single image on your website can be extremely labor-intensive. This is especially true if you consider that you somehow need to create the optimal variants for different users based on what device, OS, or browser they are using.

In-code strategies, like a JS plugin, responsive images, or CSS media queries tend to bloat your code and lead to other performance issues we’ll discuss below.

Luckily, there are plenty of CDN services available designed specifically for providing some degree of automated image optimization. These platforms analyze the context (i.e., a specific mobile device model, OS version, and browser version) of the user trying to load one of your images and try to serve them a version of the image that’s ideally optimized for them.

However, any media optimization platforms still require installing a small JavaScript plugin to dramatically improve the image and video optimization capabilities.

The one exception here is ImageEngine. ImageEngine uses WURFL device-detection to pick up every possible detail of the user’s device. The logic is built into their device-aware edge servers and doesn’t rely on you adding any additional code or markup to your website pages.

So, not only does it reduce your image payloads by up to 80% and serve them via a global CDN, but it doesn’t leave a footprint in your website’s code. As a bonus, it also happens to support the widest range of image/video formats, including animated GIFs, as well as client hints and save-data mode.

3. Render-Blocking JavaScript And CSS Is Delaying Page Loads

JavaScript is the de facto programming language for adding interactivity and advanced features to websites today. Likewise, CSS is the standard for adding styling. Both are critical components for almost any modern website.

However, nothing good comes free, and both may impact the performance of your website, particularly when used carelessly.

The following are some steps you can take to minimize the impact of these assets on your website performance:

Minify your JavaScript and CSS files.
Combine a large number of JS/CSS files into fewer files.
Replace some of your external JS and CSS files with inline JS/CSS. (Don’t overdo this! Inline JS and CSS is only suitable for small code snippets).
Defer loading JavaScript until after all your content is loaded and use media queries for CSS files.

Because media can have a more significant impact on your page weight, this leads some to believe that adding more JavaScript is the lesser of two evils.

However, depending on whether you already have render-blocking JS, Google might flag this as a completely new issue. Regardless, it will negatively impact your performance score in tools like PageSpeed Insights:

You can avoid it altogether by using an optimization engine like ImageEngine that doesn’t require any JavaScript.

4. You’re Not Using A Content Delivery Network (CDN)

A CDN is a network of servers spread across various regions all over the globe. What it basically does is store a copy of your website on each of these servers. When an internet user visits your site, the CDN automatically serves your website from the nearest server to that user.

What this does is allow your website to load faster, no matter where in the world people are visiting it from. If your website was only hosted on a single server, say somewhere in the U.S., then it could take much longer to load for a visitor located in Asia than one in the U.S.

While they all basically do the same thing, different CDNs are better at handling different types of content. Cloudflare, Fastly, and Akamai are just some of the most popular general-purpose CDNs around. Image CDNs like ImageEngine are purpose-built to not only serve image and video assets but to also optimize them using compression, formatting, etc.

So, the two main factors to consider are the type of content you want to deliver via the CDN and its global coverage. However, it’s usually possible to use multiple CDNs in tandem to cover different types of content and reach a wider area.

5. There’s Excessive Overhead In Your Database

If you have a website with any type of complexity, you probably have a corresponding database. In fact, all WordPress websites require a database to function.

Over the years, a lot of information moves in and out of the database. Sometimes, the data can get lost along the way or become obsolete. If you don’t regularly spring-clean your database, then this can really start to add up. Not only will it bloat the storage size of your database, but it will start to impact the speed of database queries and requests.

CMS users are especially prone to racking up these kinds of artifacts from plugins and themes that have been installed and removed over the years.

Unfortunately, there aren’t many easy fixes for this issue available. With most hosting providers, you’ll probably need to use phpMyAdmin to manually check and scrub your data. If you have a managed hosting solution, the host’s support team might be able to help you out. In the event that you have a locally installed database, there are some tools you can use, although they’re not 100% effective.

The best way to avoid any issues is to make database maintenance part of your routine and to learn the basics of how databases work.

6. You Have Too Many Plugins Or Themes Installed

For CMS users, plugins or themes offer near-limitless potential to spruce up the design and functionality of their website. However, each plugin or theme comes with additional code and content that add to the overall complexity and size of your website.

If you have a hand-coded website, the same goes for any additional applets or libraries you want to add to your site.

The best way to combat this is to be conscientious when adding any extras to your website. Only install what you really need or want, and make sure to uninstall and properly remove them if you don’t need them anymore.

As mentioned, they might leave various transients or artifacts behind, so you should keep an eye out for them throughout your website files (not just the database) whenever you do some spring cleaning.

7. You Aren’t Utilizing Caching

Caching is often one of the most effective yet ignored techniques for improving website performance. Caching stores your website content in fast-access memory in the user’s browser, allowing it to be loaded near-instantaneously by users. This can include everything from text to stylesheets to images to JavaScript files.

Without caching, a user will need to redownload everything when they navigate to or reload a page — whether or not anything has changed.

However, not properly configuring caching on your website can lead to issues, such as users only loading out-of-date content. Most high-quality caching tools have built-in features that automatically clear the cache when you make changes to a specific website page or content. So, users will only reload content once it has been modified.

Some hosts offer out-of-the-box caching tools with their hosting service. CMS can also usually find plugins for this, such as WPRocket for WordPress.

8. Ads Are Dragging You Down

In the end, ads are just another form of media that increases the overall weight of your website pages. While they are typically small and lightweight, multiple ad placements can really start to add up.

What aggravates the issue is that ads are loaded from external sources. This means they’ll take longer to render, generate more requests, and may mess with how stable your pages load — affecting your core web vitals.

Depending on how important ads are to your revenue stream, you’ll want to carefully consider how many ads you use on your site, where to position them, and when they load. If possible, avoid loading ads at the same time as the rest of your page, especially interstitials.

Conclusion

As you can see, website performance is a multi-faceted subject. Although some may be worse than others, you can’t just address one area and expect your website to suddenly be performant.

However, some general principles apply:

Keep HTTP requests low by limiting the number of files required for each of your website pages.
Maintain proper code hygiene and spring clean transients and leftover artifacts.
Invest in proper hosting infrastructure as well as a CDN for your website.
Optimize your media assets to significantly bring down payloads without sacrificing engagement.

The final point deserves another shoutout. As we’ve pointed out, finding an optimization solution for your media, particularly images, is probably the best thing you can do to improve your website performance. From purely a performance perspective, there is no service quite as effective as ImageEngine. It’s also the one that requires the least amount of technical expertise and ongoing maintenance.

Regardless, you’ll want to run some tests using tools like PageSpeed Insights so you can gather data on what issues your website is facing. From there, you can prioritize fixes to make your website more competitive.
