The 5 Skills You’ll Need to Land a Web Dev Job

Blog

Here at TechLaunch, we take a no-nonsense approach to web dev. We don’t waste time with excessive theorizing, learning about “legacy” technologies, or spelling out the “elopment” in web development. Our students come to us to help them get into new careers, so we focus on the only things that truly matter: the skills that employers are actually looking for in the 2018 job market, like for example how TikTok algorithm works.

Understanding the DNS Process , How Website Is Found

Blog

You might have the best web site design for florists, but do you ask yourself, “What is DNS?” “Do I need to use DNS?” Do you feel confused? In some cases, DNS can be convoluted and complicated. Let’s talk about Domain Name System (DNS) services. When you need to access a website, you type the domain name, such as www.google.com, into the web browser instead of typing an IP address. A conversion happens between www.google.com to 172.217.12.46, an IP, which designated to a device on the Internet. This conversion is a DNS query, an integral part of devices connecting with each other to communicate over the internet. To understand the DNS query process, let’s talk about how a DNS query routes through different components, and is important to protect your…

Blog

Fetch API has become the standard for web API requests for a while now and it is supported in almost any modern browsers nowadays.

Introducing Ionic 4

Blog

By Max Lynch Today I am thrilled to announce the 4.0 release of Ionic Framework, lovingly known as “Ionic for Everyone.” Ionic 4 represents the culmination of more than two years of research and hard work transforming Ionic from “mobile for Angular” into a powerful UI Design System and app framework for every web developer in the world. There are so many things to talk about with this release, but first I’d like to talk about how we got here. The Angular Years Back in 2013 when we started working on Ionic Framework, we sought to build rich JavaScript-powered components for building quality mobile apps with web technologies, and distribute them as custom HTML tags that any web developer could use in their apps. Unfortunately, there was no standard way…

Animating URLs with Javascript and Emojis

Blog

You can use emoji (and other graphical unicode characters) in URLs. And wow is it great. But no one seems to do it. Why? Perhaps emoji are too exotic for normie web platforms to handle? Or maybe they are avoided for fear of angering the SEO gods? Whatever the reason, the overlapping portion on the Venn diagram of "It's Possible v.s. No One Is Doing It" is where my excitement usually lies. Graphically animating URLs is a new thing. So I decided to put a little time into the possibilities of graphical characters in URLs. Specifically, with the possibility for animating these characters by way of some Javascript. Loopin' First off, make sure your page's Javascript code is being labelled as UTF-8 or you're gonna have a bad time putting…

Understanding Transport Layer Security TLS .

Blog

TLS is the critical Internet infrastructure that makes commerce, trust, and confidentiality possible. Transport Layer Security is on the short list for "most important security protocol on the Internet." It is designed to enable client-server applications like web browsers and servers to securely communicate over the Internet, protecting against eavesdropping, tampering, and message forgery. Each party can know that the other is who they claim to be. TLS is the technological descendant of Secure Sockets Layer and is often referred to casually as SSL. The earlier SSL versions were developed by Netscape Communications. In the late 1990s, after AOL bought Netscape, the Internet Engineering Task Force (IETF) took over the protocol. Version 1.0 of TLS had only small differences compared with SSL 3.0.…

The Ultimate Guide To Proper Use of Animation in UX

Blog

Nowadays it’s hard to impress or even surprise with an interface animation. It shows interactions between screens, explains how to use the application or simply directs a user’s attention. While exploring the articles about animation, I found out that almost all of them describe only specific use cases or general facts about animation, but I haven’t come across any article where all rules concerning animation of interfaces would be clearly and practically described. Well, in this article I won’t write anything new, I just want to collect all the main principles & rules in one place, so that other designers who want to start animating interfaces don’t have to search for additional information. Duration and speed of the animation When elements change their state or position, the duration of the…

Fundamentals Of Web Applications Security .

Blog

Over the past ten years, we have heard much about the security of web applications, and the threats that can come from using them. For better or worse, modern businesses have become increasingly dependent on the use of web applications developed agile; from complex infrastructure systems to IoT devices. Attacks on web applications provide intruders with ample opportunities such as: -Access to a company's internal resources and sensitive information; -The opportunity to disrupt the functioning of an application or bypass business logic; -Financial gains for the attacker, and losses, both financial and reputational, for the owner of web applications. Users of web applications are at risk, because if an attack is successful, the intruder can steal credentials, perform actions on websites on behalf of users, and infect a system with…
