I’ve been lucky enough to be invited to do about 25 talks over the course of the past few years and I have quite a few upcoming gigs as well, most of them at international conferences around Europe and the US. Despite my speaking experience, I’m still very reluctant to call myself a “professional speaker” or […]
After the WWDC keynote, I was convinced I would buy a new MacBook Air. I was looking forward to any announcements about new hardware during the event, as my 13″ 2010 MacBook Pro (Henceforth abbreviated as MBP) was becoming increasingly slow and dated. Also, I wanted to gift my MBP to my mother, who is […]
Note: To understand the following, I expect you to know how regex lookahead works. If you don’t, read about it first and return here after you’re done. I was quite excited to discover this, but to my dismay, Steven Levithan assured me it’s actually well known. However, I felt it’s so useful and underdocumented (the only references to […]
A common dilemma while teaching (I’m not only talking about teaching in a school or university; talks and workshops are also teaching), is whether it’s better to first teach some easy special cases and then generalize, or first the general case and then present special cases as merely shortcuts. I’ve been revisiting this dilemma recently, […]
¿What’s the animation-direction property?
¿Is alternate reverse and reverse alternate (either would be allowed) a better value for animation-direction over alternate-reverse?
¿If so, should redundant combinations of normal with alternate or reverse also be allowed, such as normal alternate?
¿Or maybe we should ditch it altogether and replace it with animation-reverse, accepting values of none, all, even, odd?
As much as I like .net magazine, I was recently outraged by their “Texturizing Web Type” article. It features a way to apply a texture to text with -webkit-mask-image, presenting it as an experimental CSS property and misleading readers. There are even -moz-, -o- and -ms- prefixes for something that is not present in any […]
I’m often asked how I got into web development, especially from people that haven’t met many women in the field. Other times it’s people with little kids and they are asking for guidance about how to steer them into programming. I promised them that I would write a long post about it at some point, […]
A few days ago, the incredibly talented Roman Komarov posted an experiment of his with pure CSS “scrolling shadows”. If you’re using Google Reader, you are probably familiar with the effect: In Roman’s experiment, he is using absolutely positioned pseudoelements to cover the shadows (which are basically radial gradients as background images), taking advantage of […]
I was working on a project today, when I realized that I had forgotten to commit for days (local only repo). I switched to my terminal, spent at least five minutes trying to decide on the commit message before settling to the completely uninformative “Another commit”. Embarrassed with myself, I shared my frustration with twitter: […]
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” […]
