HTML APIs: What they are and how to design a good one

I’m a strong believer in lowering the barrier of what it takes to create rich, interactive experiences and improving the user experience of programming. I wrote an article over at Smashing Magazine aimed at JavaScript library developers that want their libraries to be usable via HTML (i.e. without writing any JavaScript). Sounds interesting? Read it […]

One year of pastries

Last September, I was approached by Alex Duloz, who invited me to take part in his ambitious new venture, The Pastry Box Project. Its goal was to gather 30 people (“bakers”) every year who are influential in their field and ask them to share twelve thoughts — one per month. For 2012, that field would […]

In defense of reinventing wheels

One of the first things a software engineer learns is “don’t reinvent the wheel”. If something is already made, use that instead of writing your own. “Stand on the shoulders of giants, they know what they’re doing better than you”. Writing your own tools and libraries, even when one already exists, is labelled “NIH syndrome” […]

A List Apart article: Every time you call a proprietary feature “CSS3”, a kitten dies

My first article in ALA was published today, read it here: Every time you call a proprietary feature “CSS3”, a kitten dies Some comments about it on twitter:

Optimizing long lists of yes/no values with JavaScript

My newest article on Smashing Magazine’s coding section is for the geekiest among you. It’s about how you can pack long lists of boolean values into a string in the most space-efficient way. Hope you enjoy it 🙂

Help the community: report browser bugs

Thought I’d let you know that my Smashing Magazine article with that title was published today. It discusses why, how, when and where to report browser bugs, as well as how to make a good bug report. Get comfortable and make a big cup of coffee before you dive in, as it’s quite long (4000 words).

Tag editing UIs

I had to build the edit tags interface for an application I’m working on, so I took a good look at how these are implemented across many popular applications nowadays. It seems there are a few patterns that are used over and over, and I’m unsure which one is the most preferable by users, they […]

The curious case of border-radius:50%

Admittedly, percentages in border-radius are not one of the most common use cases. Some even consider them an edge case, since most people seem to set border-radius in pixels or –rarely– ems. And since it’s not used very frequently, it’s still quite buggy. A bit of a chicken and egg case actually: Is it buggy […]

Organizing a university course on modern Web development

About a year ago, prof. Vasilis Vassalos of Athens University of Economics and Business approached me and asked for my help in a new course they were preparing for their Computer Science department, which would introduce 4th year undergrads to various web development aspects. Since I was always complaining about how outdated higher education is when […]

On CSS counters plus a CSS3 Reversi UI

CSS Counters have a lot more potential than most web developers seem to think. The common use case consists of something like: somecontainer { counter-reset: foocount; } Ε { counter-increment: foocount; } Ε::before { content: counter(foocount) “. “; } commonly used to add numbering to section headings or re-create an <ol>’s counters in order to […]
