Please Don't Scroll Past This Can you chip in? The Wayback Machine is fighting for universal access to quality information; we keep the record straight by preserving government websites, news articles, historical data, and more. The Internet Archive, which runs this project, is a nonprofit, and we’d be deeply grateful if you'd join the one in a thousand users that support us financially. We unders
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
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

This repository contains KVM/QEMU Windows guest drivers, for both paravirtual and emulated hardware. The code builds and ships as part of the virtio-win RPM on Fedora and Red Hat Enterprise Linux, and the binaries are also available in the form of distribution-neutral ISO and VFD images. If all you want is use virtio-win in your Windows virtual machines, go to the Fedora virtIO-win documentation f
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

tlsdate: secure parasitic rdate replacement tlsdate sets the local clock by securely connecting with TLS to remote servers and extracting the remote time out of the secure handshake. Unlike ntpdate, tlsdate uses TCP, for instance connecting to a remote HTTPS or TLS enabled service, and provides some protection against adversaries that try to feed you malicious time information. On Debian GNU/Linux

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
