  Some Thoughts on Twitter's Availability Problems

As a regular user of Twitter I've felt the waves of frustration wash over me these past couple of weeks as the service has been hit by one outage after another. This led me to start pondering the problem space [especially as it relates to what I'm currently working on at work] and deduce that the service must have some serious architectural flaws which have nothing to do with the reason usually thrown about by non-technical pundits (i.e. Ruby on Rails is to blame). Some of my suspicions ...

  A re-introduction to JavaScript

Introduction Why a re-introduction? Because JavaScript has a reasonable claim to being the world's most misunderstood programming language. While often derided as a toy, beneath its deceptive simplicity lie some powerful language features. 2005 saw the launch of a number of high-profile JavaScript applications, showing that deeper knowledge of this technology is an important skill for any web developer. It's useful to start with an idea of the language's history. JavaScript was created in 1...

  Should All Web Traffic Be Encrypted?

The prevalence of free, open WiFi has made it rather easy for a WiFi eavesdropper to steal your identity cookie for the websites you visit while you're connected to that WiFi access point. This is something I talked about in Breaking the Web's Cookie Jar. It's difficult to fix without making major changes to the web's infrastructure. In the year since I wrote that, a number of major websites have "solved" the WiFi eavesdropping problem by either making encrypted HTTPS web traffic an accou...

  The Best Wireless Headphones for Everyday Use

Wireless headphones have consumed a little bit of slamming during the previous six months, complying with Apple's debatable choice to clear the newest set of Apple iPhone of the reliable old earphone port. HTC observed fit using the U Ultra and also in businesses and undergone lots of objection from both customers and market professionals. Several sets are more concentrated on sports and also exercise and set in additional functions to perform so that some others are created mainly for hearing t...

  Impact of AI on UI/UX design

The growth of computerization and Artificial Intelligence implanted into our regular daily existences in the course of recent years is only productive, we're no longer talk about fantasy since machines are going on at this very moment. This quick advancement has propelled a radically new age of designers to search for client-focused arrangements through the extent of these innovations. Along these lines, we need to investigate what this implies for UX plan in 2018 and what standards we should gr...

  Java is not the new COBOL

If you Google “Java is the new COBOL” you’ll find a glut of articles proliferating this mantra. I don’t know its origins, however I’m inclined to think it’s mostly repeated (and believed) by the Ruby community. Ruby, from a developer’s perspective is a low-friction language. A developer can just sit down at a text editor and start banging out code without really thinking about such superflous things as types. Java on the other hand, well, you h...

  How To Find a Great Start-Up Idea

Most people believe that the first step to starting a new company is to have a great idea. Back in business school, there were countless “idea brainstorming” sessions where groups of students would try to come up with the next billion dollar idea. None of them ever turned into anything.Great businesses are not built on ideas for marginal improvements or incremental features, they solve real problems and require a deep understanding of what those problems are. So the absolute worst th...

  A String is not an Error

I decided to write a little article to discourage an unfortunately common pattern in Node.JS modules (and browser JavaScript, to a lesser extent) that can boil down to these two examples: // A:function myFunction () {  if (somethingWrong) {    throw 'This is my error'  }  return allGood;} and // B: async Node.JS-style callback with signature `fn(err, …)`function myFunction (callback) {  doSomethingAsync(function () {    // …    if (...

  Processing Unicode Data in Python - A Primer to Understand Non-English Data Processing

Introduction: Currently we live in a world where people of diverse cultures/backgrounds use electronic devices to express their ideas, do their daily work that earns them their daily bread, and entertain themselves using content that is created using their own language and so on. Naturally, in order to make all these things happen, any computational instrument, be it a laptop or a desktop computer, or a smartphone, or something else, should be capable enough to serve all of these things in a man...

  Building the new AJAX mail UI part 2: Better than templates, building highly dynamic web pages

This is part 2 of a series of technical posts documenting some of the interesting work and technologies we’ve used to power the new interface (see also part 1, Instant notifications of new emails via eventsource/server-sent events). Regular users can skip these posts, but we hope technical users find them interesting. As dynamic websites constructed entirely on the client side become de rigueur, there are a number of templating languages battling it out to become the One True Wayâ„...
