Changing std::sort at Google’s Scale and Beyond
TL;DR; We are changing std::sort in LLVM’s libcxx. That’s a long story of what it took us to get there and all possible consequences, bugs you might encounter with examples from open source. We provide some benchmarks, perspective, why we did this in the first place and what it cost us with exciting ideas from Hyrum’s Law to reinforcement learning. All changes went into open source and thus I can
HTTP/2: The Sequel is Always Worse
Assuming you're already familiar with HTTP/1, there are only three new concepts that you need to understand. Pseudo-HeadersIn HTTP/1, the first line of the request contains the request method and path. HTTP/2 replaces the request line with a series of pseudo-headers. The five pseudo-headers are easy to recognize as they're represented using a colon at the start of the name: :method - The request m
Understanding Wi-Fi 4/5/6/6E/7 (802.11 n/ac/ax/be)
This paper details how Wi-Fi works in the United States. While most of this paper also applies to other countries, there will be subtle Wi-Fi differences (supported channels, Tx power allowed, etc) for other countries, for which Wikipedia has the details. Faster navigation TIP: As you scroll through this paper, headers are 'sticky' and remain docked at the top of the web browser window. Clicking a

⚙ D54604 Automatic variable initialization
Add an option to initialize automatic variables with either a pattern or with zeroes. The default is still that automatic variables are uninitialized. Also add attributes to request uninitialized on a per-variable basis, mainly to disable initialization of large stack arrays when deemed too expensive. This isn't meant to change the semantics of C and C++. Rather, it's meant to be a last-resort whe

Bing検索の裏側―BitFunnelのアルゴリズム - Hatena Developer Blog
はてなアプリケーションエンジニアの id:takuya-a です。 この記事では、Microsoft の検索エンジン Bing で採用された BitFunnel アルゴリズムを紹介します。 昨年のエンジニアアドベントカレンダーでは、文字列検索のアルゴリズム全般について紹介しました（文字列アルゴリズムの学びかた - Hatena Developer Blog）。今年はそのなかでも、インデックス（索引）を使った全文検索アルゴリズムについてのお話になります。 この記事の前半は全文検索の入門にもなっていますので、検索技術になじみがない方にも楽しんでいただけるのではないでしょうか。 逆に、「そんなのもう知ってるよ！」という方は、本題である「BitFunnel アルゴリズムの詳細」から目を通していただければと思います。 この記事は、はてなエンジニア Advent Calendar 2017の21日目の
