Functional Reactive Programming on iOS with ReactiveCocoa | Teehan+Lax
Note: This is going to be a slightly more technical post geared toward our friends in the iOS developer community. Objective-C is a programming language which often finds itself mired in the antiquated ways of C, the programming language upon which modern Objective-C is built. While improvements in computing power have advanced the state of art in programming language design, Objective-C sometime
Getting Started with ReactiveCocoa | Teehan+Lax
Note: This is going to be a slightly more technical post geared toward our friends in the iOS developer community. In my previous post, I covered high-level aspects of ReactiveCocoa, the Objective-C framework that allows developers to write apps declaratively. Now I’d like to introduce some patterns in ReactiveCocoa, discuss a few best practices, and outline common gotchas to be on the lookout for
エネルギーの先行き、原発利用とシェールガス
今週のアップデート １）核放射線–敵か味方か？ その１ 福島の被害は社会的ストレスがもたらした 核放射線–敵か味方か？ その２ 原子力への恐怖を取り除く試みを オックスフォード大学名誉教授のウェイド・アリソン氏らでつくる「放射線についての公的な理解を促進する科学者グループ」の小論を、アリソン氏から提供いただきました。 この小論では、放射線は医学治療などで使われ、利用者はリスクと効果を見極めようとしていることを紹介しています。ところがエネルギーでの利用では、放射線への恐怖が先行し、その活用が遅れているといます。福島についても過度の防護基準に基づいて行動することによる社会損害の大きさを指摘しています。 ２）米シェールガスはなぜバブルなのか？ エネルギー・コンサルタントの小野章昌氏の論考です。アメリカを中心に「シェールガス革命」と呼ばれるガスの増産が期待され、はやされています。大量のガス、オイル
ライブドア事件と日本資本主義の「失われた7年」 日本経済に新陳代謝の復活を | JBpress (ジェイビープレス)
懲役2年半の実刑判決を受けて服役していた旧ライブドアの堀江貴文元社長が3月27日朝、収監先の長野刑務所から仮釈放された。とりあえずおめでとうと言いたいが、この事件は彼個人の問題を超えて日本経済に大きなダメージを与えた。 ライブドア事件の起こった2006年ごろには、小泉政権の下で日本の資本市場でも動きが出ていたのだが、この事件後の村上ファンド事件などで企業買収を犯罪のように考える風潮が強まり、資本市場の改革も止まってしまった。それ以来の歳月は、日本資本主義の「失われた7年」だった。 ライブドア事件で資本市場は死んだ ライブドア事件で問われた粉飾決算は53億円と、2000億円を超えたカネボウなどに比べれば粉飾決算としては小規模であり、組織的犯罪でもなく悪質性も低い。それが実刑になった量刑の不自然さもさることながら、企業グループ内部の利益処分で刑事罰に問われたという事実が、多くの企業に恐怖を与え
Journey Through The JavaScript MVC Jungle — Smashing Magazine
When writing a web application from scratch, it’s easy to feel like we can get by simply by relying on a DOM manipulation library (like jQuery) and a handful of utility plugins. The problem with this is that it doesn’t take long to get lost in a nested pile of jQuery callbacks and DOM elements without any real structure in place for our applications. When writing a Web application from scratch, it
Building Social Software for the Anti-Social
19 Dec 2011 Building Social Software for the Anti-Social In November, I delivered the keynote presentation at Øredev 2011. It was the second and probably final presentation in the series I call Building Social Software for the Anti-Social.
