Open-Source Snake Game in WIN32 and jQuery

Thu, 03 Sep 2015 15:13:45 +0000

This is a simple snake game available in both WIN32 and JavaScript versions. The WIN32 version was written in 2010 – small but complete. Looking back, I’m quite impressed with myself from over five years ago. The jQuery version was written in 2015.

jQuery demo: http://www.coinidea.com/game/snake/

The overall interface looks like this:

Snake Definition

The entire snake is a List, with a head squarehead, a direction with four possible values, a speed, and the current snake length List.size().

Collision Detection

When the snake’s head encounters a randomly generated square in the current direction, it means food has been eaten.
When the snake turns back and hits its own body, or hits the boundary, the game is over.

Bookworm Helper Tool

Thu, 12 Feb 2015 15:54:15 +0000

While organizing old files recently, I stumbled upon a small program I wrote around 2011.

Have you ever played a game called Bookworm? It’s made by PopCap. The game tells the story of a bookworm defeating a demon, and to progress and fight bosses, you need to spell words. If I recall correctly, you’re given a 3x3 or 4x4 matrix containing letters a-z or * (representing any letter), and you need to spell the longest word possible – the longer the word, the more damage dealt to the demon. So I wrote a little program to help my not-so-great vocabulary spell the longest words possible. It requires a word list as a prerequisite; there’s a dictionary.txt in the project’s doc folder containing about 7000+ words that needs to be loaded first.

Main program interface:

Loading the dictionary:

Entering characters:

Getting the result list:

GitHub: https://github.com/hujiulin/Bookworm

Project notes:

Written in C++ around 2011 [the code is a bit messy]. Can be opened with VC 6.0 or Visual Studio.
This program finds the longest possible words.
Input letters [a-z or *] to get a list of answers. [* represents any letter]
This was my first ever small program. I recently found it among old files, so I’m sharing it here :).

Adding Images to README.md on GitHub

Thu, 12 Feb 2015 12:42:27 +0000

I had been using SVN before and only truly started using Git a few months ago. I had briefly used GitHub during KDD2013.

Recently, I wanted to polish my programs properly – comments and descriptions are essential and should be written with care.

I encountered a problem: how to add images to a README.md file.

Here is the solution I used:

Create an image folder within your project folder, place the images you want to display in the README.md, and commit that folder to GitHub. Through the preview, you can obtain the image’s URL on GitHub.

README.md supports the following image markup: <img data-original="image-url" src="http://blog.coinidea.com/wp-content/themes/9IPHP/images/lazy_loading.gif" alt="image" />

Batch Word to HTML -- ConvertWordToHTML [Update: Word Converter Tool]

Sun, 11 Jan 2015 10:34:33 +0000

I recently had a requirement to batch convert Word files to HTML.

For a small number of Word files, you can simply use Word’s built-in “Save As” feature. But when dealing with a large number of Word files, it becomes quite complicated.

After searching online, I found solutions in PHP, Python, Ruby, and C#. Among them, I found a tool called “Xunjiie Converter”, but it didn’t quite fit my needs, so I decided to write my own. Since Word is a Microsoft product, I figured C# might be the best choice for this task.

I open-sourced a GUI-based solution on GitHub: https://github.com/hujiulin/ConvertWordToHTML [Currently single-threaded; will be converted to multi-threaded later].

Screenshots of the running application:

Initial program interface:
“Open” to select an input folder containing Word documents:
“SaveAs” to select an output folder:
Program finished running:
Input and output results:

Program notes:

Dependencies: Windows OS, .NET Framework 3.5, Office Word
Word’s “Save As HTML” offers several format options: single web page (mht), web page (htm), and filtered web page (htm). I chose the filtered HTML option, which converts all formulas to gif or jpg images. A properly filtered htm file won’t contain Microsoft’s messy formatting information.

2015-1-24 Update:

Rename solution and project to WordConverter; Add feature: convert word to PDF; ADD feature switch specified ext;

The Word Converter tool now supports both HTML and PDF formats.
