ホモトピー型理論(HoTT)に入門するために

前置き

HoTTに興味があるCS系の学生が、HoTT本の冒頭を読んだ体験を元に、知っておくと学び易くなりそうな話をまとめてみた。

対象は自分と同じ、型理論は少し知ってる^[1]けどホモトピーとかわからんという人。「型理論は知らんけどホモトピー論と圏論の用語はわかる」という人はそのまま本読めばいいと思うし、両方ともわからない人は学ぶモチベーションがよくわからない(し、とりあえずどちらかを学んだ方がいいと思う)のでとりあえず無視する。

HoTTについてはさわり程度の知識しかないまま書かれているため、話半分に読んでもらった方がいいと思う。

1. 「依存型に触ったことある」もしくは「TaPLを部分的にでも読んだ」あたりが基準になるだろうか。

I am passionate about Ruby, but its execution time compared to other languages is extremely high, especially when we want to use more complex algorithms. In general, data structures in interpreted languages become incredibly slow compared to compiled languages. Some algorithms such as ´n-body´ and ´fannkuch-redux´ can be up to 30 times slower in Ruby than Go. This is one of the reasons I was interested in embedding Go code in a Ruby environment.

For those who do not know how shared libraries operate, they work in a similar way as DLLs in Windows. However, they have a native code with a direct interface to the C compiler.

Note Windows uses the DLL system, and in this case, this does not necessarily have to be in native code.

One example is DLLs written in C#, which runs on a virtual machine. Because I do not use windows, I ended up not testing if it is poss

Building a GraphQL API in Rails - Part 1

This is a series blog post cover above three topics of GraphQL:

1. About GraphQL
2. Building a basic API with Rails
3. Some best practices

GraphQL is not a new thing, it already exist for a while, the reason I decide to investigate it is because Github released their GraphQL API alpha currently. We know Github has been a very good company for a long time, their RESTful API also becomes some kind of standard for developers, so it's pretty interesting to see what’s new they've been released.
