Dmitry Baranovskiy’s Web Log vcard

The amazing week of Web Directions is over. This year was significant for me, because I did a smooth move from listeners to speakers. My session was pretty good, without “Oh, shit!” moments and tricky questions. In fact questions were very different, yet very simple to answer. I’ve put together slides from the presentation on slideshare. All the demos are on Vimeo.

I should also mention that I won third prize at Web Jam 8 with my Raphaël presentation. You can watch video of it on Vimeo.

It also was nice to catch up with lots of people from virtual world of Internet. This was the first year when I am actually missed a lot of folks and didn’t chat with them. Sorry, I haven’t done it on purpose. The conference was too short and I can’t stay for after‐party. Looking forward for Web Directions South ’09. See you there!

Well, to be honest, I haven’t done a thing. New 2.1 Software Update add SVG support for iPhone & iPod Touch, so apparently all the demos for Raphaël now work on “iTouch” products. That is what happens when instead of supporting products you support technology. Go Web Standards!

Another thing: I moved project to GitHub to socialise it better. Hope it will help you in your daily coding job.

Basically Opera is the best so far. Safari doesn’t support filters. Firefox has problems with fonts and doesn’t support animation.

I am pleased to announce that because of my bandwidth limitation I have to drop down Raphaël hosting.

But! There are always friends who can help in hard moment, so I am happy to introduce http://raphaeljs.com

Special thanks goes to:

• Lachlan Hardy: for the whole idea, amazing support and awesome spirit. He organised whole move.
• Andrew Krespanis: for awesome hosting and incredibly fast sysadmin setup.
• Lincoln Stoll: for whipping up the appropriate .htaccess file to redirect everything smoothly.

You can change you bookmarks now.

Go and check my panel description. It is called “JavaScript Ninja Secrets” and going to be awesome if it make it to the final. So please, vote for me and/or wish me a luck.

Dustin Diaz put an interesting task on his blog. In short, you have an array:

var arr = ["a", "b", "c", "c", "d", "e", "e", "e", "e", "e",
"f", "e", "f", "e", "f", "a", "a", "a", "f", "f", "f"];

and it should be turned into string like this:

"a b c c d e e <span>e e e</span> f e f e f a a <span>a</span> f f
<span>f</span>"

First solution in my mind is this:

alert(arr.join(" ").replace(/([a-z])\s\1\s((\1\s?)+)(?=\s|$)/g,
"$1 $1 <span>$2</span>"));

But I feel like a cheater, probably I missed some limitation in the task. Will submit it and wait for comments from Dustin. In case I got it wrong, I will update the post.

Update

Just in case I have to use forEach function:

var arr = ["a", "b", "c", "c", "d", "e", "e", "e", "e",
           "e", "f", "e", "f", "e", "f", "a", "a", "a", "f", "f", "f"];
Array.prototype.forEach = function (f) {
    for (var i = 0, ii = this.length; i < ii; i++) {
        f(this[i], i, this);
    }
};


var res = "", isTag = false;
arr.forEach(function (item, index, ar) {
    if (!isTag && ar[index - 1] == ar[index - 2] && ar[index - 2] == item) {
        res += "<span>";
        isTag = true;
    }
    res += item;
    if (isTag && ar[index + 1] && ar[index + 1] != item) {
        res += "</span>";
        isTag = false;
    }
    if (ar[index + 1]) {
        res += " ";
    } else if (isTag) {
        res += "</span>";
    }
});
console.log(res);

Want to share my little excitement: my business card made it in “70 Amazing Business Cards”. That was a bit of surprise, because I am not a designer, and my cards are very cheap indeed.

In continuation of my previous post here is my implementation of times method of then Number object.

Number.prototype.times = function (f) {
    (function (i) {
        i && arguments.callee(--i) && f(i);
        return true;
    })(this);
};

The idea is that you should be able to write code like this one:

var a = [4, 2, 6, 1, 8, 0];
a.length.times(function (i) {
    alert(a[i]);
});
