May 21, 2022 blog code

This is a remake of a previous post due to its popularity. Let’s consider a PyTorch network and a Tensorflow/Keras network. If they are in exactly the same architecture, we should be able to copy the weight parameters from one to another. But how? [more]

In a previous post I mentoned about bringing the old vim config to neovim by making symlinks between ~/.vim to ~/.config/nvim as well as ~/.vimrc to ~/.config/nvim/init.vim. But as I see neovim getting mature, seems I don’t need to care about vim config any more. While the .vim files are... [more]

Arpa's trick explained

April 27, 2022 blog code

Recently I encountered with the problem of range minimum query (RMQ) and there are many ways to solve it, depending on the trade off between preprocessing complexity and per-query runtime complexity. Block-paritioning and a sparse table would be clever techniques. A hybrid of both would need some more code but... [more]

In Python, Django is the most popular web framework. Second comes to Flask. What Flask is handy to do is to create some RESTful APIs by defining the web endpoints and the handlers. The frontend, however, is not something Django or Flask can provide to you. The best they can... [more]
