こんにちは。中川です。 先日行われたカヤックさん [1]とクックパッドさん [2]主催の「技術者交流会 ～おいしいソースのつくり方～ 」 [3]のライトニングトークで発表させていただきました。 たくさんの技術者の方と交流でき、発表も聞けて料理もおいしく、非常に充実した時間を過ごせました。 関係者の皆様、このような機会を設けていただきありがとうございました。 さて、当日はHTML5のcanvasと、ドロネー三角形分割という技術を使って写真をポリゴンっぽくするデモを発表しました。 特徴点を手で打っておけば後は自動で面を生成します。 プレゼン資料： http://seeds.ville.jp/electriccafe/slides/ [4] デモ： ※Firefox3.0.9、chrome2.0β でのみ動作を確認しています。 IEやSafari、chrome1.0では動きません。 1)ドロネー

javascript - には整数はない : 404 Blog Not Found
2009年05月22日15:00 カテゴリLightweight Languages javascript - には整数はない 違います。 javascriptで整数の変数を強制的に符号なし整数に変換する方法 ? ku javascriptの整数は内部的には32bit intで扱われていて(Firefox3.1, Chrome0.2の場合)、演算の結果が0×80000000を超えると自動的に負の値になります。 事実はもっと驚くべきものです。 以下をご覧下さい。 puts = make_puts(document.getElementById('ttyp0')); for (var n = 1; n <= 54; n++){ puts(2, '**', n, ' - 1 = ', Math.pow(2, n) - 1); } 2の32乗どころか、2の53乗まできちんと計算できていますが、54

s0lnic on blog - jQuery vs Prototype - part II
Recently, new versions of jQuery and Prototype have been released – it’s a perfect moment for a part number 2. On the official Prototype blog we can read that the general performance of CSS selectors is now improved, unfortunately only for Safari 3, but Element#up/#down/#next/#previous should now be faster on all browsers, it’s a good news as they were really slow. On the other hand we have jQuery

John Resig - Javascript Diff Algorithm
Using an idea grabbed from a mailing list post, I implemented the diff algorithm discussed in the following paper (free registration required): P. Heckel, A technique for isolating differences between files Comm. ACM, 21, (4), 264–268 (1978). The implementation, itself, has two functions, one of which is recommended for use: diffString( String oldFile, String newFile ) This method takes two string

とてもシンプルに自分自身が属する script 要素を取得 - IT戦記
グローバル領域に以下の一行を書く <script> var currentScript = (function (e) { if(e.nodeName.toLowerCase() == 'script') return e; return arguments.callee(e.lastChild) })(document); alert(currentScript); </script>こうすることで、currentScript はこの script 要素を指す。 いちおう説明 DOM は構築されるときに、上から順番に構築される。そして、script タグがあると、 script 要素を構築したあとに、スクリプトを実行する。 つまり、スクリプトが実行されたとき script 要素は今まさに作られたばかりであり、それよりも後ろの要素が存在しない。さらにこの script 要素を含むすべての要
