In this series of posts, I want to walk you through how to build a simple, persistent key-value store. We will be using an on-disk hashtable(also called external hashtable) to store the key-value mappings. In this post, I will explain hashtables briefly and an algorithm called linear hashing. In the next post, we’ll look at an implementation of linear hashing(written in Rust). How would you store
Welcome to the Python Packaging User Guide, a collection of tutorials and references to help you distribute and install Python packages with modern tools. This guide is maintained on GitHub by the Python Packaging Authority. We happily accept contributions and feedback. 😊 Overview and Flow# Note Building your understanding of Python packaging is a journey. Patience and continuous improvement are
A call to action for maintainers to support themselves and move forward. Big notable projects like Linux and Node.js have comforting long term support cycles that ensure Enterprises and other production users can continue to use a release for years without migrating to a new one. The ecosystems built on top of these projects tend to try and follow a similar cycle. They keep old releases in their C
tt: logical tools for logic¶ Welcome to the documentation site for tt! Warning tt is heavily tested and fully usable, but is still pre-1.0/stable software with no guarantees of avoiding breaking API changes until hitting version 1.0. Synopsis¶ tt (truth table) is a library aiming to provide a Pythonic toolkit for working with Boolean expressions and truth tables. Please see the project site for gu

ソフトウェアエンジニアの間でも一般的な言葉になった「機械学習」。本書では、その機械学習やデータ分析の道具をどのようにビジネスに生かしていけば良いのか、また不確実性の高い機械学習プロジェクトの進め方などを「仕事で使う」という観点から整理し… オライリージャパンさんからは、売れ行きがとてもいいという話を伺っており、これで新しいノートPCを買う足しになるかなぁと思っています。 物理本については少数ですが、Cloudera World Tokyo2017で限定販売されるそうです。CWT2017申し込みが始まったので、物理版がほしい方は申し込むとよいんじゃないでしょうか。 書評もいくつか届いており、勝手ながら紹介させていただきます。

Second Edit: The Github user suriyadeepan made a PyTorch port as well! Over the past year, I’ve spent most of my working time doing deep learning research and internships. And a lot of that year was making very big mistakes that hel
注 継続的にいいねもらっているのですが、知識が浅い頃に書いたので、不正確なところがあります。今度直します。 私のGIS、重すぎ GIS使っていますか? GISで利用するデータが多くなればなるほど、やりたい処理が増えれば増えるほどこう思うはずです。 地理情報くらいコードで扱わせろやとおもうあなたのためにあるいは地理空間情報入門者のためにまとめてみました。 そもそも地理空間情報、位置情報とは 地理空間に紐付いた情報。ある点や線、面、空間が地球上のどこに位置するかを表す情報を含む情報です。地球は歪な楕円であるためさまざまな手法があります。測量は真面目にやるとすごく複雑になるので軽く触れるだけですが(私も理解しきれていないし) 経度、緯度、高度(省略されることも)を持つもの 地球上の限られた範囲を無理やり直行座標とみなし、その平面内の位置を表したもの などのパターンがあります。どの方法で座標を表し
Python is becoming popular day by day and has started to replace many popular languages in the industry. The main reason for Python’s popularity is because of the following reasons: Python is popularly known as Beginner’s language because of it’s simplicity.Python helps developers to be more productive from development to deployment and maintenance.Python’s syntax is very simple and high level whe
A beginner's guide to building a simple database-backed Flask website on PythonAnywhere: part 2 Oct 16, 2017 by giles Welcome to the second part in our tutorial for getting started with Flask development on PythonAnywhere! This is a continuation of our previous tutorial, so if you haven’t been through it, you should do that first. In particular, this tutorial will assume that you’re starting with
Over the past few months, I have been collecting AI cheat sheets. From time to time I share them with friends and colleagues and recently I have been getting asked a lot, so I decided to organize and share the entire collection. To make things more interesting and give context, I added descriptions and/or excerpts for each major topic.
