I read a blog post by Alex Muscar, “Beautiful Binary Search in D“. It describes a binary search called “Shar’s algorithm”. I’d never heard of it and it’s impossible to google, but looking at the algorithm I couldn’t help but think “this is branchless.” And who knew that there could be a branchless binary search? So I did the work to translate it into a algorithm for C++ iterators, no longer requir

Reading and writing binary formats is hard, especially if it’s an interchange format that should work across a multitude of platforms and languages. Have you ever found yourself writing repetitive, error-prone and hard-to-debug code that reads binary data structures from files or network streams and somehow represents them in memory for easier access? Kaitai Struct tries to make this job easier —

Debian now has a debuginfod server available for its users. Please keep reading this page if you would like to know how to configure your system to use debuginfod. TL;DR: How do I configure my system to use debuginfod? As of version TBD, libdebuginfod (part of the elfutils package) will automatically install a file named /etc/profile.d/debuginfod.sh which contains the proper configuration to make

RFC 8949 Concise Binary Object Representation “The Concise Binary Object Representation (CBOR) is a data format whose design goals include the possibility of extremely small code size, fairly small message size, and extensibility without the need for version negotiation.” JSON data model CBOR is based on the wildly successful JSON data model: numbers, strings, arrays, maps (called objects in JSON)
Linuxバイナリを最適化して性能を向上させる「BOLT」、Facebookがオープンソースで公開。言語やコンパイラに依存せず高速化 Facebookは、Linuxバイナリの内部配置を最適化することによりCPUのキャッシュ効率などを向上させ、実行速度を改善する「BOLT」をオープンソースで公開しました。 BOLTは「Binary optimization and layout tool」の略とされています（もしかしたら、より速く走るという意味でウサイン・ボルト氏にかけているのかもしれません）。 BOLTは言語やコンパイラに依存せず、ソースコードも不要 BOLTのおもな効果は、Linuxバイナリの実行状況をperfコマンドで取得し、高頻度で実行されている部分などを判別した上で、そうした部分がCPUキャッシュにヒットしやすいようにバイナリの内部配置を改善することなどで実行速度を向上させることと

Here at balena we have thousands of users working through our getting started process, we found there was no easy way for our users to flash an SD card that we could recommend to everyone. So we built Etcher, an SD card flasher app that is simple for end users, extensible for developers, and works on any platform.
