Compress
•Download as ODP, PDF•
0 likes•228 views
When a web page is requested, the browser receives and stitches together various components like images, stylesheets, and JavaScript. To improve load times, these components can be compressed by the server before being sent, then decompressed by the browser. However, not everything can be compressed, like images, and compression is not always beneficial, such as with many small files versus one large file. The effectiveness of compression depends on the specific makeup of each website.

This allows JavaScript to set up objects and classes to make assumptions without round trips to the server, improving performance. Popular frameworks like Backbone, Ember, Angular, Knockout, and Meteor emphasize separating UI from logic, data binding, templating, and routing to enable single-page applications. Meteor stands out by using the same syntax on client and server and web sockets for automatic UI updates.
Lecture11
The document discusses including static and dynamic resources in web pages for modular web programming. It recommends including common elements like navigation bars using server-side includes or JSP includes to avoid duplicating code. This allows changing the layout in one file rather than every page. It provides examples of including static files using <%@ include %> and dynamic JSP files using <jsp:include>.
Node.js primer
Node.js allows JavaScript to be run on the server side using the Google Chrome V8 JavaScript engine. It utilizes non-blocking I/O and event looping to remain lightweight and efficient compared to traditional threaded models. Node.js exposes APIs for common non-blocking operations like file systems, networking, and cryptography that prevent blocking and allow highly scalable servers to be built with a single thread. Many large companies use Node.js in production for building scalable web servers and APIs.

How To Dramatically Speed Up Your Website Using A Caching Plugin
If you’re tired of having to wait for your website to load on your browser each and every single time, then your customers and clients are probably even more annoyed than you.
But, of course, they don’t have access to your website’s backend, so they can’t do anything about your site’s speed. They’re technically at your mercy if they choose to wait for your site to load.
However, chances are they’re going to just up and leave your site altogether, never to be seen again. No matter how good your content is and how awesome your products are, if your site is slow, then you’re going to get dismal conversion rates, if at all.
The question is, why would you subject your visitors to torturous waiting when they don’t have to?
The thing is there are plenty of ways you can follow to speed up your website – and web caching is probably one of the most important methods all webmasters should follow.
While those who’ve been building sites for a long time probably already know all about caching, a novice webmaster may feel overwhelmed.
Admittedly, web caching can be quite technical, and it is but normal to feel like a deer stuck in headlights!

Leeward WordPress Meetup- Caching and Website Speed
This document discusses how caching can improve website speed. It begins by explaining how websites load files sequentially and sets a goal of under 2 seconds. It recommends getting a fast web host as the first step, then optimizing images, code minification/concatenation, and lazy loading. There are different types of caches like browser, server, and memcache caches that store content to reduce load times. Common caching plugins like WP Super Cache and W3 Total Cache are recommended, or paying for WP Rocket for e-commerce sites. The key steps are to get a fast host, optimize the site, then cache it to improve performance.
AJAX for Scalability
AJAX allows web pages to be updated asynchronously by exchanging data with a web server behind the scenes, allowing parts of a page to change without reloading the entire page. Tuenti uses AJAX extensively to update parts of their single-page application, caching content on both client and server sides for scalability. They route requests to different server farms based on client location and cache content to improve performance. Tuenti serves billions of images per day using multiple CDNs and pre-fetches content to minimize load times.

Note of CGI and ASP
This document provides an overview of common gateway interface (CGI) and active server pages (ASP) for generating dynamic web pages. It explains that CGI involves running a separate process for each request, which can reduce performance. ASP was developed to address this by allowing tags to be inserted into web pages that are replaced with dynamic data when the page loads, without needing a separate process. The document also describes how form data is received in CGI and the basic workflow of CGI and ASP programs.

Why You Should Replace Windows 11 with Nitrux Linux 3.5.0 for enhanced perfor...
The choice of an operating system plays a pivotal role in shaping our computing experience. For decades, Microsoft's Windows has dominated the market, offering a familiar and widely adopted platform for personal and professional use. However, as technological advancements continue to push the boundaries of innovation, alternative operating systems have emerged, challenging the status quo and offering users a fresh perspective on computing.
One such alternative that has garnered significant attention and acclaim is Nitrux Linux 3.5.0, a sleek, powerful, and user-friendly Linux distribution that promises to redefine the way we interact with our devices. With its focus on performance, security, and customization, Nitrux Linux presents a compelling case for those seeking to break free from the constraints of proprietary software and embrace the freedom and flexibility of open-source computing.

Removing Uninteresting Bytes in Software Fuzzing
Imagine a world where software fuzzing, the process of mutating bytes in test seeds to uncover hidden and erroneous program behaviors, becomes faster and more effective. A lot depends on the initial seeds, which can significantly dictate the trajectory of a fuzzing campaign, particularly in terms of how long it takes to uncover interesting behaviour in your code. We introduce DIAR, a technique designed to speedup fuzzing campaigns by pinpointing and eliminating those uninteresting bytes in the seeds. Picture this: instead of wasting valuable resources on meaningless mutations in large, bloated seeds, DIAR removes the unnecessary bytes, streamlining the entire process.
In this work, we equipped AFL, a popular fuzzer, with DIAR and examined two critical Linux libraries -- Libxml's xmllint, a tool for parsing xml documents, and Binutil's readelf, an essential debugging and security analysis command-line tool used to display detailed information about ELF (Executable and Linkable Format). Our preliminary results show that AFL+DIAR does not only discover new paths more quickly but also achieves higher coverage overall. This work thus showcases how starting with lean and optimized seeds can lead to faster, more comprehensive fuzzing campaigns -- and DIAR helps you find such seeds.
