Blog

I am writing my blog whose articles are mostly about programming. [Here (mostly ja and codes)]

Other documents

• My claims about the design of java.util.List. The conclusion is that the design is unreasonable. [Here (en)]
• About the design of javax.swing.tree.TreeModel in term of interactive software like visualization softwares. The paper first clarify the innate problems in TreeModel design and proposes a better design instead. [Here (en)]
• All public API should not depend on List or Set interfaces. Instead, we should use Iterable and Iterables of Google Collections! [Here (en)]
• The problem of interface is that it does not support backward-compatibility. This article shows one solutions to solve it. [Here (en)]
• A strategy to build a usable library is presented. Especially concerned with the dependency to existing modules representing data. [Here (en)]
