• Shortcomings of web technologies in building a robust desktop application.

    As computation power and data are shifting to the edge, web applications are more and more like installed desktop applications with (limited) file system access, threading, offline storages… Frameworks such as Electron, which allow browser-based application to be packaged as standalone app, are gaining popularity. However, with great power comes great responsibility. Javascript, html, css have always been used to build webpages, which is a stateless and forgiving environment. A broken webpage can be remedied by hitting refresh button. The web is not used to be fast, users’ expectation for it is lower than for an installed application.

    Nature has always been a central focus of the Japanese culture, in the religion, architecture, food. Japanese Garden is an attempt to embrace nature and bring human closer to nature. A trip to the Koishikawa Korakuen Garden with the Tokyo City Guide club has taught me much.

  • Concurrency in Java context

    Concurrency is an unavoidable fact in web development if the page ever gets pass more than one user (which is pretty much any service out there). But concurrency also poses a problem to data consistency. This post is a back-to-the-basics summary of techniques I’m aware of.

  • Running Odoo 8 on Pypy

    Pypy has not reached the point of compatibility that one could simply switch the interpreter. Some libraries need to be replaced, or installed with latest development code. Still, one can get the Odoo web running with a few changes.

  • Tornado Non-blocking Smtp Client

    Recently, I was developing a tornado-based web application at work. The idea of using Tornado is to base the whole web application on Tornado’s single-threaded IOloop, which enables the application to handle higher load compared to using other multi-threaded model (given the same hardware). Since there is no additional thread spawned to handle concurrent requests, no memory overhead. And besides, that help avoids context-switching cost when the program control is passed between threads.
