Shipping Go [Manning]

Thanks to the (very friendly) reviewers team at Manning I just got my hands on the newly released Shipping Go, and first of all I had a great time reading from start to finish which hasn’t happened in a long time as far as IT books go. I was actually pleasantly surprised. the amount of code in the book is kept to a minimum the focus is on keeping the product to a minimal set of features, shows how to push a quality code out, and to a various set of plateforms and environments (and why both production and developpers environment should be kept as close as possible to each other ) The book focuses and explores the lifecycle of go projects in particular, but the techniques presented can be easily reused in the scope of other languages.

LondonAirquality Analysis with IcCube

If you do analytics, you probably usually go straight for Python Notebooks, and create a bunch of graphs to visualize the analysed data. When you don’t want to show that data to someone outside, and hide implementation details, a nice alternative, and my de facto favourite, is to go and use IcCube. As an exercice, I was teaching how to get ready and graph quickly with IcCube, using air quality data.

Writing an API Wrapper in GoLang

I had a really time-limited effort to do to prove how to write a command line wrapper for an open API a customer is developping. The target Rest API is the jquants-api, as presented in a previous post. I chose to implement the wrapper in GoLang, which proved to be extremely fast and pleasant to do. The task was eventually done in a short evening, and the resulting Golang wrapper with core features has been uploaded on github.

Loom - Fibers, Continuations and Tail-Calls for the JVM

I am excited about Project Loom. The project focuses on easy to use lightweight concurrency for the JavaVM. Nowadays, the JavaVM provides a one java thread to one OS thread model to the programmer. While it’s actually the current Oracle implementation, it used to be that many JavaVM versions ago, threads provided to the programmer were actually green threads. Project Loom goes down that road again, providing lightweight threads to the programmer.

Tokyo Stock Exchange Jquants API

The just out of beta jquants-api propose sets of daily financial data from over 4000 listed companies on the Tokyo Stock Exchange. Currently, the sets of data that can be accessed via the API are: Listed Issue Information Stock Price Information Market Information with more to come in the near future. While current historical data is only available starting from 2017 users are encouraged to provide feedback to the API via usual github (etc.
