php5.3 Assigning the return value of new by reference is deprecated - 為せば成る・・・かもしれない
「為せば成る 為さねば成らぬ何事も 成らぬは人の為さぬなりけり」という言葉がありますが やっても出来ない事は出来ないものです。 出来ない事は出来ないとはっきりさせませんか？
iOS5で久しぶりにわくわくしてきたので、ブログの更新が増えるといいですね。ところで、Automatic Reference Counting (ARC) が非常に気になるので、ちょっと調べてみました。英語力とコンパイラについての知識があまり豊富でないので、間違っているところもあるかもしれませんが、ある程度納得できたのでまとめてみます。 Automatic Reference Counting(以後ARC) は、簡単に言うと retain/release を自動挿入する技術で、手動でやっていた参照カウンタを自動でやってくれるものです。したがって、ARCの対象となるのはObjective-Cのオブジェクトとなります。このオブジェクトにはBlocksオブジェクトも含まれますが、Core Foundationのオブジェクトは含まれません。 ARCを使うには、いくつかの制約があります。詳しくはAR

NumPy reference# Release: 1.26 Date: September 16, 2023 This reference manual details functions, modules, and objects included in NumPy, describing what they are and what they do.

SELECT COUNT(*) INTO before_count FROM table1; ... INSERT INTO table1 ...; ... SELECT COUNT(*) - brefore_count INTO registered_count FROM table1; なにかTABLEへの追加処理をしてますが、意図通りにできたかどうか、前後で COUNT(*)をとって、その差分を報告させようとしています。 複数のプロジェクトの複数のオーナーのコードで見かけたので、こんな初級アンチパターンも共有しときます。 なにがまずいの? COUNTは、シーケンシャル・スキャンしないと出てこない値なのです。アンチパターンでは、テーブル全体が対象ですから、主キーインデクスを総なめです。小さいテーブルのうちはいいのですが、運用の1000万行を越えるような巨大テーブルだと、主キーインデック

MySQL provides several functions that you can use to perform calculations on dates, for example, to calculate ages or extract parts of dates. To determine how many years old each of your pets is, use the TIMESTAMPDIFF() function. Its arguments are the unit in which you want the result expressed, and the two dates for which to take the difference. The following query shows, for each pet, the birth

概要 プライベートで勉強のためにずっとSwiftでiOSアプリ開発をしてまして、それがやっとひと段落してAppStoreに公開することができました。 気づけば無駄に長い道のりでしたが何とかストアの公開までできたので、アプリ開発経験が実質ゼロだった状態からリリースまでの道のりをまとめておこうと思います。 作ったもの まずは作ったものを簡単にご紹介します。 とてもシンプルなアプリです。 https://itunes.apple.com/jp/app/meshi-log/id1173943494 自分が食べた写真をメモと一緒に管理できるアプリです。 いつ何を食べたかまとめておきたいなーと思って作りました。 スキルセット まずは自分のスキルセットを軽くご紹介しておきます。 仕事では基本的にPHPをメインで触っています。(あとはjsを少々。。) アプリ開発は実質未経験です。実質というのは一応仕事で少
