Wudi — Fri, 01 Jul 2022 13:20:35 +0000

On Windows 10, when you choose to use small button on taskbar, the icons in quick launch bar will have alignment and scaling problem:

So I wrote a custom quick launch bar based on WPF and DeskBand, which can correctly deal with these problems:

Bought a Sermoon V1 3D printer, and tried making the first self-designed part

Wudi — Sun, 30 Jan 2022 11:03:20 +0000

Before the Spring Festival, I bought a 3D printer of Creality, model Sermoon V1:

I chose this model mainly because it just fits on my shelf. With the Core XY structure, it need no extra space to move back and forth the printing platform:

Below is what the attached whistle example prints out:

Today I designed a fixing accessories for a small electric grinder in Fusion 360. The software provided by Creality is easy to use. I did not change most of the default parameters, and the first try is successful:

View on GitHub: https://github.com/wudicgi/SpleeterMsvcExe

SpleeterMsvcExe is a Windows command line program for Spleeter, which can be used directly.

It is written in pure C language, using ffmpeg to read and write audio files, and using Tensorflow C API to make use of Spleeter models. No need to install Python environment, and it does not contain anything related to Python.

Furthermore, SpleeterMsvcExe reduced the memory usage through segmented processing, hence it can handle single audio file over 30 minutes. Due to the length-extending process, all segments can be concatenated seamlessly.

Released an open source clipboard utility - Clipboard Auto Processor

Wudi — Sun, 19 Jul 2020 12:16:15 +0000

View on GitHub: https://github.com/wudicgi/clipboard-auto-processor

Here are the readme contents:

1. Introduction

Clipboard Auto Processor is a utility to process the text in clipboard automatically. Unlike other clipboard enhancement softwares which could only manage the history contents, this tool can execute any script to process the content automatically.

The script can be written in any language that you are familiar with, such as PHP, Python or JavaScript. It only needs to implement the conversion from original text to desired result. Other works will be all done by Clipboard Auto Processor.

2. Usage

Download the latest release version, and extract it to any location that have write permission. Generally any folder except Windows, Program Files and C drive root is OK.

When the ClipboardAutoProcessor.exe is running for the first time, it will create the config.ini file based on the current system language. And then you can edit this file to set script interpreter, display font and other options.

You can manually create the shortcut, and put it into start menu or on desktop. But it is more recommended to use a launcher, such as Launchy, Wox and Keypirinha, to quickly open and use at any time.

3. Sample scripts

Convert the backslashes in copied path list (js, php, python)

Adjust the text format copied from PDF document (php)

Generate array define code from hex string (php)

BeatShow @ Maker Faire Beijing 2018

Wudi — Sun, 18 Nov 2018 14:15:32 +0000

October this year I took part in the Maker Faire Beijing 2018, as an individual, to exhibit the BeatShow automatic music light show system which is made in my spare time.

The event was hold at National Indoor Stadium East Plaza. And it was originally scheduled to be open during National Day holiday (10.1 - 10.7), but delayed to mid-October later, due to some irresistible reasons.

Below is what my exhibition stand looks like.

Before move-out in the last day, I shooted some videos. Afterwards, I shooted some more videos in dark indoor environment. Below is the final clip:

Permanently disable driver signature enforcement in Windows 8.1

Wudi — Fri, 30 Sep 2016 18:30:50 +0000

For some unsigned driver, you must disable driver signature enforcement to make it work. In Windows 8.1, this operation requires a reboot. And the settings is not permanent. It will backed to default enabled after turning on again or restart normally.

Through search, I found the program Driver Signature Enforcement Overrider from the post Permanently disable driver signature enforcement on Win 8.1 x64. It could disable driver signature enforcement permanently.

Although there is no Win 8.1 in its Supported OS list, it could work. Just follow its built-in instructions:

So how do I use it?

First and foremost; you are using this software at your own risk, we do not

take responsibility for any damages to your system, but we do not believe it

can harm anyone anyway. Secondly, User Account Control (UAC) must be

disabled in-order to use this tool as well.

1. Go ahead download and launch the application from the link below. Inside

its main menu, press on the "Enable Test Mode" button and follow the

instructions on the screen. This will enable TESTSIGNING mode, which

allows unverified system files to be loaded.

2. Now all you have to do is to add the unverified signature to the required

system files. To do so press on the "Sign a System File" button from the main

menu, and enter specific filename including full path. For example: if

ATITool64.sys from C:\Windows\System32\drivers refuses to load due to

driver signature enforcement, you should type: "C:\Windows

\System32\drivers\ATITool64.sys", and if you would like to sign more than a

single file, just repeat this procedure until you’re done, and finally reboot.

After you enabled Test Mode and added signatures to the required system

files, they should bypass Windows’s driver signature enforcement and load

without any issues. However, if for some reason you are interested to revert

it, you can re-launch the application, choose "Disable Test Mode" from the

main menu, and reboot. If you encounter issues or having questions, feel free

to post it on our forums.

FileSystemFinder: A PHP library that can list files and directories hierarchically using wildcard and regex patterns

Wudi — Sun, 17 Jan 2016 06:35:52 +0000

Actually, this PHP library was created in the National Day holiday last year. But at that time, it was not as complete as it is now.

Today I cleaned up the code, made a few improvements, and commited it to github:

https://github.com/wudicgi/file-system-finder

The example is as follows:

<?php
include_once 'FileSystemFinder.php';
 
// List files using static method FileSystemFinder::find()
 
$filelist = FileSystemFinder::find('C:/php/ext/php_pdo_*.dll');
 
print_r($filelist);                 // via __debugInfo()
echo "\r\n";
 
 
// List files using file() method with a wildcard pattern
 
$filelist = (new FileSystemFinder('C:/php/ext'))
    ->file('php_pdo_*.dll');
 
print_r($filelist->toArray());      // using toArray()
echo "\r\n";
 
 
// List files using dir() and file() method with wildcard and regex patterns
 
$filelist = (new FileSystemFinder('C:/php'))
    ->dir('dev|ext')                                    // using default wildcard matcher
    ->file('/[0-9]/', FileSystemFinder::REGEX_MATCHER); // using the specified regex matcher
 
foreach ($filelist as $path) {      // via SeekableIterator interface
    echo "$path\r\n";
}
echo "\r\n";
 
 
// A combination of using both static and non-static method
 
$filelist = FileSystemFinder::find('C:/php/dev|ext', FileSystemFinder::DIR_ONLY);
print_r($filelist);
 
$filelist = $filelist->file('/[0-9]/', FileSystemFinder::REGEX_MATCHER);
print_r($filelist);
 
echo "\r\n";
 
 
// List files using wfio extension
 
if (extension_loaded('wfio')) {
    $filelist = FileSystemFinder::find('wfio://E:/Music/* 笑话/* 欢乐剧场/??? *大*.wma');
 
    for ($i = 0; $i < count($filelist); $i++) {     // via Countable interface
        echo "[$i] => $filelist[$i]\r\n";           // via ArrayAccess interface
    }
} else {
    echo "The wfio extension is not loaded.\r\n";
}
 
?>

This will output:

Notepad++ with enhanced PHP syntax highlighting

Wudi — Sun, 01 Nov 2015 13:32:05 +0000

During the National Day holiday, I searched for a alternative text editor and intend to use Notepad++. But when I start using it, I found its syntax highlighting feature is a bit weak.

From this article, I knew that the Scintilla editor component using by Notepad++ uses hard-coded method to deal with syntax highlighting. To add a new type of highlighting keywords, you need to modify the C++ source code. As for the problem that keywords and function names are mixed together for PHP, it has been there for 9 years.

I could have put it away and looking for commercial softwares. But I felt the well-known Sublime Text is not good as well after trying it out. So I came back to consider modifying the source code of Notepad++. Through the modification on Oct 5, I had figured it out and commited it to the repository I forked on github:

https://github.com/wudicgi/npp-customized

Today, I merged the code of v6.8.6 to my enhanced branch

This is the PHP syntax highlighting result in original edition:

And below is my enhanced version:

Now, in the Style Configurator, you can specify the PHP keywords (WORD) and function names (FUNCTION) to different colors:

Wrote a new PHP library: HtmlMinerDocument

Wudi — Tue, 06 Oct 2015 13:50:32 +0000

During the National Day holiday, I wrote a new PHP library by which you can retrieve DOM elements from HTML using the simple CSS selector syntax.

Now I have commited it to github, at:
https://github.com/wudicgi/html-miner-document

The usage is straightforward. For example, the code below could retrieve the title and link of all headline news from Netease News:

<?php
include_once 'HtmlMinerDocument.php';
 
// Find all elements matching the given CSS selectors
 
$doc = new HtmlMinerDocument(file_get_contents('http://news.163.com/'));
 
$news_list = $doc->findAll('div.ns-wnews h3 a');
 
foreach ($news_list as $news) {
    echo "$news[text] ($news[href])\r\n";
}
 
echo "\r\n";
?>

And using the code below, you can get all threads from the collection forum of amobbs:

<?php
include_once 'HtmlMinerDocument.php';
 
// Find elements by group
 
$doc = new HtmlMinerDocument(file_get_contents('http://www.amobbs.com/forum-9892-1.html'));
 
$threads = $doc
    ->findFirst('table#threadlisttableid')
    ->findAll('tr')
    ->findAllByGroup(array(
        'title'         => 'th a.s',
        'author'        => 'td.by cite a',
        'last_reply'    => 'td.by em span'
    ));
 
foreach ($threads as $thread) {
    echo $thread['title']['text'];
    echo ' by ' . $thread['author']['text'];
    echo ' (' . $thread['last_reply']['text'] . ')';
    echo "\r\n";
}

MPC-HC 1.7.8 arrow mouse pointer version

Wudi — Tue, 10 Mar 2015 12:56:16 +0000

MPC-HC (Media Player Classic Home Cinema) has an annoying problem that confused me for years. So I used the old Media Player Classic 6.4 which was released in 2006 all the time.

But now, due to the 64-bit version of Win 7 and Win 8.1 operating system, it's time to replace the old media player.

Referring to a bug reported on MPC-HC's website, I searched through the source code of MPC-HC and made some modifications. Eventually, all the 4 places need to modify was fixed to the default style of old MPC 6.4.

Below is the mouse pointer assigment from original version:

Below is the modified version, same to MPC 6.4:

Algorithm for finding nearby places - Geohash

Wudi — Thu, 29 May 2014 07:21:16 +0000

Geohash is a well-known algorithm for searching nearby places. Today, on the regular meeting of laboratory, I talked about the idea and C implementation of this algorithm. Now, I shared the slideshow here for reference.

Download: http://blog.wudilabs.org/uploads/geohash_ppt_by_wudi.pdf (Chinese)

If you have looked at it, you may found there is an C implementation for geohash. Now, the basic functions of this library have been completed. After I clean it up, I will publish it together with a NMEA parser library which do not use malloc dynamic memory allocation.

Getting the audio waveform data of media file using ffmpeg.exe in C#

Wudi — Mon, 30 Dec 2013 02:32:51 +0000

Previously, I use the NAudio library to implement this function. It needs to extract the audio track of a media file to a separate WAV file to deal with. Even with the help of RAM disk, the processing speed is still very slow.

Yesterday, I searched again for the usable audio processing library in C#. But there is still no better choice. Finally, the popular cross-platform command line tools mencoder, ffmpeg and so on came into my head. The ffmpeg seems to work because it support stdout output.

At first, I tried to output the binary stream in WAV format to stdout. But I found that in this situation, ffmpeg will write a placeholder for size information in head, and seek back to rewrite it after the whole stream is outputed (source). When the output target is the stdout stream instead of a file, this rewriting operation will fail, which causes the obtained WAV stream to have wrong head information and cannot be used.

The reason that I use WAV format is just because it is the most familiar audio format that storing raw waveform data. But after read the documentation of ffmpeg, I found that it supports a great many formats. It can output integers or floats directly, without head information. At last I selected the little endian 32-bit float format.

The complete code is as follows:

using System.Diagnostics;
using System.IO;
 
// ...
 
static void Main(string[] args)
{
    // ...
    string path = @"E:\Media\test.mp4";

    proc.StartInfo.RedirectStandardOutput = true;

    proc.ErrorDataReceived += new DataReceivedEventHandler(proc_ErrorDataReceived);
    proc.Start();
    proc.BeginErrorReadLine();
    ProcessStream(proc.StandardOutput.BaseStream);
 
    proc.WaitForExit(10000); // 10s
    if (!proc.HasExited)
    {
        proc.Kill();
        Environment.Exit(1);
    }
    // ...

Music Beat Tracker Demo

Wudi — Tue, 19 Nov 2013 05:15:06 +0000

I wrote a realtime music beat tracker algorithm based on FPGA and ARM these days.

The prototype of this algorithm is written in M-code of MATLAB. The video below is the lighting effect demonstration using the result from MATLAB. Pay attention to select high definition or above quality when watching, or the intensity of frame may change due to compression.

At present, the computational load of this algorithm is too heavy and memory usage is too large. Moreover, it failed to achieve the expected effect. So I will try to develop a new algorithm with smaller computational complexity.

The video below is a few days earlier. It is the music beat tracker preview to the last song "True Romance" in the video above.

AutoJewel 0.1.0 -- a program that plays Bejeweled 3 automatically

Wudi — Sat, 06 Aug 2011 12:05:16 +0000

Today I spent all day modifying the program that can play Bejeweled 3 automatically, which is first mentioned in June. It was just a prototype written in one night at the beginning, but now it is not too bad to release. I have put the source code and binary files on Google Code.

Download source (AutoJewel-0.1.0-src.zip)
Download binaries (AutoJewel-0.1.0-bin.zip)

Instructions: Run Bejeweled and AutoJewel at the same time. After setting the parameters properly, enter the corresponding game mode in Bejeweled. And then press the default global hotkey Ctrl + F8 to make AutoJewel start running.

Something I want to say, is that currently this program does not have any intelligence. So do not compare it with the high-level players, and it cannot be normal any more that the scores it got are lower than many human players.

As I have said in the previous entry, this program is aimed at the visual effects of Bejeweled, rather than a high score. And it was coded to play mainly the Lightning mode. Other modes are just be supported passingly. For example it plays Ice Storm mode totally the same way as Lightning mode. As for the Classic mode, it only slows down the speed and gives the match on the top a higher priority.

Lightning mode (highest multiplier is 9, final score 4194k)

Ice Storm mode (highest multiplier is 8, final score 1517k)

Classic mode (achieved level 13, final score 743k)

Balance mode (purely for fun)

TesseractDotnet Example

Wudi — Sat, 16 Jul 2011 07:45:20 +0000

Download source (TesseractDotnetExample.zip)

The use of TesseractDotnet is quite simple, except for the lack of references (the Tesseract itself does as well). For example, to OCR an image which is treated as a single line text, the code below works well:

using System;
using System.Drawing;
using tesseract;
 
// ...
 
TesseractProcessor processor = new TesseractProcessor();
 
bool succeed = processor.Init(@"..\tessdata\", "eng", 3); // TesseractEngineMode: DEFAULT
if (!succeed)
{
    // Deal with error
    Application.Exit();
}
 
processor.SetVariable("tessedit_pageseg_mode", "3"); // TesseractPageSegMode: PSM_SINGLE_LINE
 
Image image = Image.FromFile("...");
 
processor.Clear();
processor.ClearAdaptiveClassifier();
 
string result = processor.Apply(image);
 
// ...

But there is one point requiring particular attention. The first parameter of method TesseractProcessor.Init(), dataPath, must be ended with slash "/" or backslash "\", or the initialization will be failed. When it failed, the Init() method returns false. But if you did not deal with the returned value, then when the program runs to the line calling Apply(), an exception will be throwed:

AccessViolationException:

Attempted to read or write protected memory. This is often an indication that other memory is corrupt.

The mails from 126.com seems to be rejected by php.net

Wudi — Wed, 15 Jul 2009 03:05:02 +0000

I remember that I tested the forwarding email address after I got a CVS account at php.net, and it worked fine. But today when I test it again, I found the mails sending from 126.com was rejected by php.net for the reason "4.7.1 our policy says no mail from your domain". And then I sent two mails from hotmail and yahoo, all succeeded.

Maybe the spam mails from domain 126.com are a little much. But I still intend to use this forwarding email address for the programs such as PEAR packages.

Crypt_XXTEA 0.9.0 has been released

Wudi — Thu, 06 Mar 2008 12:15:00 +0000

In November the last year, I received an email which informed me that the encryption result of my Crypt_XXTEA package differs from some other implementations. And I made a reply to explain the reason.

XXTEA is a block cipher which requires the block size is at least two words, i.e. 32 bits. If the length of string is not multiples of 4, the last block must be fill up to 32 bits by some junk data. Thus the decrypted string will have the junk data at its end too. To solve this problem, the initial version of Crypt_XXTEA appends the length of string to the end of the converted long integer array, which can be used to cut the decrypted string to get the correct result.

Rencently, considered that this default behavior may confuse the user, I made some modifications. In the version of 0.9.0, users can handle the converting between string and long integer array with their own functions.
