Python Programming - 01. Introduction

Python (programming language) is a widely used general-purpose, high-level programming language. Its design philosophy emphasizes code readability, and its syntax allows programmers to express concepts in fewer lines of code than would be possible in languages such as C++ or Java. The language provides constructs intended to enable clear programs on both a small and large scale.

jQuery - Syntax, Method, Event and Animation Effects

Many tools are useful for Fast Prototyping to develop Mobile Web Apps, jQuery and jQuery Mobile are one of the most popular solution. Before you start studying jQuery, you should know how to write simple HTML, CSS and JavaScript programs.

PhoneGap - Design MyUI as the First App

Using PhoneGap to develop Mobile Web-based Native App is very easy to add web UI modules (.js and .css) into the www folder. For example, I use jQuery Mobile.

• http://jquerymobile.com/: download the latest stable (Version 1.4.2 here) and get an zip file named "jquery.mobile-1.4.2.zip".

PhoneGap - Introduction to Mobile Web Apps

Cross-platform mobile applications are hard to develop due to different OS platforms with diverse programming languages on various IDE (Integrated Development Environment), such as Android / Java / Eclipse, iOS / Objective-C / Xcode, Windows Phone / C# / VS.NET. It is a hard technical challenge to launching mobile applications on major mobile platforms, developers must be familiar with these programming languages and IDEs to develop mobile Apps for Android, iOS and Windows.

PhoneGap - building native mobile applications using HTML, CSS and JavaScript

PhoneGap is an HTML5 application framework to develop native applications for mobile devices through integrations of web technologies, HTML5, CSS (CSS3), and JavaScript. 

The software underlying PhoneGap is Apache Cordova. The software was previously called just "PhoneGap", then "Apache Callback". Apache Cordova is open source software. ... http://en.wikipedia.org/wiki/PhoneGap

Apache Cordova is a set of device APIs that allow a mobile app developer to access native device function such as the camera or accelerometer from JavaScript. Combined with a UI framework such as jQuery Mobile or Dojo Mobile or Sencha Touch, this allows a smartphone app to be developed with just HTML, CSS, and JavaScript.

Web Programming Style - Useful Cases of CSS (2) CSS3 Selectors

CSS3 supports powerful selector to retrieve specific elements.properties and set values for flexible rendering. There are four different combinators for CSS selectors in CSS3:

QNAP/Linux Tool - wget (2) Backup the whole website and page content

In the previous blog, QNAP/Linux Tool - wget (1) Mirror Websites, the whole website html files were archived in your QNAP NAS. It's simple way to backup your blog articles, however, media contents within blogs are not fetched and archived.

QNAP/Linux Tool - wget (1) Mirror Websites

GNU Wget was developed to fetch files from the Internet (the Web), in which HTTP, HTTPS, FTP, and many widely used protocols are supported. Since 1996, wget was born for the crawling Web requirement. I firstly studied wget source code in 1998 due to developing crawler programs for search engine.

QNAP NAS - Find Useful Packages in IPKG List

In this article, we will find and try useful packages. Writing notes about the package with functions, supported architecture (ARM, x86 or x86_64), bugs and tested results.

QNAP NAS - IPKG and Optware IPKG App

QNAP NAS is a good platform for understanding the practices of developing embedded systems, since QNAP OS (QTS) is a minimized Linux OS for optimizing the performance of NAS. That is you can not install any software with only one click on setup.exe, the pre-required libraries and packages must manually installed before you can run a powerful App written with Qt for example. In Ubuntu, you are familiar with using apt-get to install packages. In QTS, you must learn how to use ipkg.
