- word2vec — This tool provides an efficient implementation of the continuous bag-of-words and skip-gram architectures for computing vector representations of words. These representations can be subsequently used in many natural language processing applications and for further research.

- What Every Frontend Developer Should Know about Page Rendering — Rendering has to be optimized from the very beginning, when the page layout is being defined, as styles and scripts play the crucial role in page rendering. Professionals have to know certain tricks to avoid performance problems. This arcticle does not study the inner browser mechanics in detail, but rather offers some common principles.

- Alice in Warningland (PDF) — We performed a field study with Google Chrome and Mozilla Firefox’s telemetry platforms, allowing us to collect data on 25,405,944 warning impressions. We find that browser security warnings can be successful: users clicked through fewer than a quarter of both browser’s malware and phishing warnings and third of Mozilla Firefox’s SSL warnings. We also find clickthrough rates as high as 70.2% for Google Chrome SSL warnings, indicating that the user experience of a warning can have tremendous impact on user behaviour.
ENTRIES TAGGED "ux"
Josh Clark and Tim O’Reilly on designing beyond screens, and beyond a single device.
As the Internet is increasingly embedded into our physical world, it’s important to start designing for physical and intentional interactions with interfaces to supplement the passive, data-gathering interactions — designing smart devices that service us in the background, but upon which we also can exert our will.
In this episode, Josh Clark (in an interview) and Tim O’Reilly (in a keynote) both address the importance of designing for contextual awareness and physical interaction. Clark stresses that we’re not facing a challenge of technology, but a challenge of imagination. O’Reilly argues that we’re not paying enough attention to the aspects of people and time in designing the Internet of Things, and that the entire system in which we operate is the user interface — as we design this new world, we must think about user needs first.
Adding consistency to Kivy's Python UI tools
Kivy has a wonderful set of built-in widgets that can be extended in numerous ways. They have very useful behaviors, but their look and feel may not integrate well with your App or the platforms you are targeting. Kivy doesn’t support theming out of the box right now, but if you poke around enough, there are a range of options you can use to customize the default look of widgets without having to define your own inherited versions of them.
I’ll first introduce you to Kivy’s image atlases, which are less mysterious than they sound, and are important groundwork for understanding theming in Kivy. Then you’ll learn two different ways to do manual theming in Kivy, with an eye to future automation.
To understand theming, you must first understand atlases. An atlas is essentially a collection of distinct images combined into a single image file for loading efficiency. A JSON file describes the location of the separate images inside that master image file so that Kivy can access them directly. If you’ve ever worked with CSS sprites, you know exactly what I’m talking about. If you haven’t, the following example should explain everything.
A truly accessible website is both accessible and usable
Every time I give a talk about making accessible websites, I get the following question:
“What checklist do you use to make sure a site is accessible?”
My response always surprises them:
“I don’t use a list.”
Why not? There are so many lists out there that I could be using! Practically every US government agency has a checklist published on their site, and several non-government sites offer checklists of their own. With so many free resources, why do I ignore checklists?
Measuring impact and changing behavior
I had the opportunity to sit down with Laura Klein (@lauraklein) and talk about the importance of creating effective user experiences. Laura is a UX expert and consultant. She stresses the need to figure out what works by talking to users and determining what works through usability testing. She’s also author of O’Reilly Media’s UX for Lean Startups: Faster, Smarter User Experience Research and Design. It hit home when Laura told me, “If people aren’t getting it, you’re probably doing it wrong.”
Key highlights include:
- How to figure out what works, so you can avoid a poor user experience. [Discussed at 0:19]
- It’s important to avoid porting a traditional process to a new product and service. Instead you need to think about how to design a new and natural experience. [Discussed at 2:16]
- Think about context when designing new processes. [Discussed at 2:37]
- The first step in creating a successful UX is knowing and understanding your audience. [Discussed at 3:49]
- Using these principles beyond web sites. In all good UX applications, the goal is not to notice the interface. [Discussed at 5:16]
- It’s critical to observe people, so you’re not assuming a knowledge base. [Discussed at 7:35]
- The importance of A/B Testing. And how design is not an art; it’s trying to solve a problem. [Discussed at 9:54]
- How the build, measure, learn lean methodology fits with UX design. It’s all about measuring the impact and changing behavior. [Discussed at 11:11]

How to design products and services that help users change behavior
Steve Wendel (@sawendel) is the Principal Scientist at HelloWallet where he develops applications that help users take control of their finances. He’s also currently writing Designing for Behavior Change. I recently sat down to talk with Steve about the importance of testing and iteration, role of psychology, and resources and tools.
