From STUPID to SOLID Code!
Last week I gave a talk about Object-Oriented Programming at Michelin, the company I am working for. I talked about writing better code, from STUPID to SOLID code! STUPID as well as SOLID are two acronyms, and have been covered quite a lot for a long time. However, these mnemonics are not always well-known, so it is worth spreading the word. In the following, I will introduce both STUPID and SOLID

SSE.浮動小数点演算手動最適化は本当に効果的なのか - デー
ちょっと試したので、結果をコピペ。 概要とたてまえ SSEは、x86のSIMD命令セットに含まれる浮動小数点演算の複数同時実行を行う命令セットです。単精度(float)で4つ、倍精度(double)で2つの演算を1命令で実行できるため、うまく使うと繰り返し同じ演算のパフォーマンスアップを期待できます。 Streaming SIMD Extensions - Wikipedia 画像処理や、確率の計算などでは浮動小数点数の計算を数百万回から回数とかいうレベルではなく3日間くらいの規模で行うことがあるので、 少しでも速くなると時間的にとてもうれしい！ 計算をどこで妥協するかみたいな部分があるため速く計算を終わらせることでやれることの可能性が広がる！ という思いがあります。 CUDAのほうが云々 CUDAは、NVIDIAのGPUが対応しているGPGPUの環境です。GPGPUというのは、グラフィッ

Japanese for Programmers
You too can find work as a programmer in Japan! Programming and software development is one of the few fields where non-Japanese can find great jobs in Japan. But in order to work in Japan, it is essential to learn the Japanese language. Especially, one must know the lingo used in the field where one is working -- namely software! For this purpose, I have gathered notes during my four years worki

List of software development philosophies - Wikipedia
This is a list of approaches, styles, methodologies, philosophies in software development and engineering. It also contains programming paradigms, software development methodologies, software development processes, and single practices, principles and laws. Some of the mentioned methods are more relevant to a specific field than another, such as automotive or aerospace.[1][2] The trend towards agi
Design Patterns and Refactoring
Design Patterns In software engineering, a design pattern is a general repeatable solution to a commonly occurring problem in software design. A design pattern isn't a finished design that can be transformed directly into code. It is a description or template for how to solve a problem that can be used in many different situations. Uses of Design Patterns Design patterns can speed up the developme
