Herokuが再度料金体系変更 - flexible free dyno hoursで月1000時間の無料枠（ただし全アプリ横断で） - Qiita
Herokuが再度料金体系変更 - flexible free dyno hoursで月1000時間の無料枠（ただし全アプリ横断で）Heroku Herokuの新料金体系が発表され、Free Dynoで1日6時間のsleepが強制されるようになってはや1年。 ここにきてfree dynoのプランにまた変更が入ったようです。 Herokuから届いた案内メールによると、flexible free dyno hoursという概念が導入され、月1000時間まで無料稼働枠が割り当てられるようです。 (2016.6.2追記) 結局1日18時間に減っていた無料枠すらもなくなり、全アプリで1000時間を分け合うことになるため、より無料プランの制限が厳しくなったというのが実情のようです。 注力したい（けどお金はかけたくない）アプリが1つだけの場合は、24時間稼働に戻せるのでよさそうですが、無料で色々アプリを

On Arrays.fill, Intrinsics, SuperWord and SIMD instructions
{This post turned rather long, if you get lazy feel free to skip to the summary} Let's start at the very beginning, a very good place to start... My very first post on this blog was a short rant on intrinsics, and how they ain't what they seem. In that post I made the following statement: "intrinsic functions show up as normal methods or native methods" Which is correct. An intrinsic function is a
Fearless Concurrency with Rust | Rust Blog
The Rust project was initiated to solve two thorny problems: How do you do safe systems programming? How do you make concurrency painless? Initially these problems seemed orthogonal, but to our amazement, the solution turned out to be identical: the same tools that make Rust safe also help you tackle concurrency head-on. Memory safety bugs and concurrency bugs often come down to code accessing dat

bliki: Command Query Separation
The term 'command query separation' was coined by Bertrand Meyer in his book "Object Oriented Software Construction" - a book that is one of the most influential OO books during the early days of OO. (The first edition is the one that had the influence, the second edition is good but you'll need several months in a gym before you can lift it.) The fundamental idea is that we should divide an objec
Operationalモナドをゲームに応用した話 - モナドとわたしとコモナド
データを処理することは、プログラミングのもっとも本質的な部分である。数値、文字列、あるいはデータの集まりなどを扱うために、数々の構造が考えられてきた。Haskellにおいては、「手順」もデータとして扱うことができる。これは、DSLを作るうえで非常に有用であり、ゲーム開発やデータベース操作……手続きがかかわるあらゆるものに応用できるだろう。 手順をデータとして扱う方法として、FreeモナドとOperationalモナドがある。ここでは、Operationalモナドをゲームのキャラクターの制御に用いた例を紹介する。Freeモナドの導入については、Andres Löh氏のHaskell eXchange 2013の講演がわかりやすく、おすすめである。 データを作る アクションゲームの敵の動きとして、この二つを考えよう: 待機 接近(攻撃) 索敵(プレイヤーの位置を調べる) EnemyMというモナ

5 Free E-Books and Tutorials on SQL
We've covered several programming languages now, but we haven't really gotten into database development yet. Although NoSQL is hot, SQL (structured query language) isn't going away. Different databases (such as Oracle, MySQL and PostgreSQL) use different variations, but the idea is to have a unified system so that a developer can move from database to database with a minimum of relearning. If you'
