Now line tag has two distinct co-ordinates to draw line between two points. left using the objects (here pos1 and pos2). attr() method is used to change attributes of the selected element.Īll we did in above line is we changed attributes of line from x1 = 0Īs position() returns two values, one 'left' and other 'top', we can easily access them using. Now as we have obtained all the positions we need we can draw line as follows. For more information, visit (you can use offset() method too) JQuery position() method allows us to obtain the current position of an element. I used selectors to select the two divs and line. because we will be using jQuery to edit the attributes (x1,y1,x2,y2) of line tag. (for a reference visit w3schools.) we haven't specified them yet. Line tag allows us to draw a line between two specified points(x1,y1) and (x2,y2). (for the sake of explanation I am doing some inline styling but it is always good to make a separate css file for styling) Procedure to join two divs using a line :Ĭreate two divs and give them any position as you need

Adobe Illustrator is one of the best software used to create an complex svgs using paths. SVG images and their behaviors are defined in XML text files.

We then analyzed the cryptographic functions according to their performance in interpreted code (provided by libsodium.js), compiled code for Node.js (provided by libsodium-neon) and compiled code for native programs (provided by rust_sodium).Joining lines with svgs was worth a shot for me, and it worked perfectly.įirst of all, Scalable Vector Graphics (SVG) is an XML-based vector image format for two-dimensional graphics with support for interactivity and animation. That’s the only functionality that sets it apart from sodiumoxide.

However, rust_sodium provides an option to download libsodium in advance and integrate it into the finished Node.js module. The reason for using rust_sodium instead of the well-known sodiumoxide is that we rely on libsodium’s system functions - which means every Wire user would need to have libsodium installed, or libsodium-neon would not work at all. This interface is publicly available as “ libsodium-neon” on GitHub. We created a Node.js module that provides a JavaScript interface, which can talk to the Rust bindings of libsodium. Fortunately we came across Neon, a Rust abstraction layer for native Node.js modules.Īs Wire desktop apps are built with Electron (which runs Node.js), using Neon proved an ideal way to achieve near-native encryption and decryption performance. This speed difference between libsodium and libsodium.js forced us to look for alternatives that could increase the encryption and decryption speed in our web application. The Rust version of Proteus is tightly integrated in our mobile apps and uses the Rust bindings to libsodium, which are significantly faster than their JavaScript counterparts: The Sodium library is available for numerous platforms - a native version written in C ( libsodium), bindings for Rust ( rust_sodium) and a pure JavaScript version ( libsodium.js), which has been compiled using Emscripten. These algorithms are essential for everything that happens in Wire and are provided by the Sodium crypto library.
Wire’s end-to-end encryption protocol Proteus, originally written in Rust, makes use of cryptographic primitives from the implementations of HMAC-SHA256, Curve25519 and HKDF. The impact depends on the application - the speed difference is not very noticeable when displaying static images or text, but can have a significant effect during cryptographic calculations. This requires extra computational time during program execution compared to compiled programming languages. Since JavaScript is an interpreted language, code compilation is done at runtime.

Hardware access, offline operation, and real-time communication are the new norm for developers, and JavaScript serves as the foundation for these technologies.
It was the right decision by Brendan Eich when he created JavaScript in 1995 to make interactive websites a reality.īut the internet has evolved since then, and so have the expectations of users and web developers. JavaScript, the web’s programming language, was built for programmer productivity at the expense of performance efficiency. However, there’s one major challenge with web applications. This inspired us to build a web version of Wire that anyone could use in a WebRTC-enabled browser. One of the defining principles behind web technologies is building things once and making them available everywhere regardless of the device or platform.
