About 16-bit OS attempts (2)
At the end of the last article, I posted a large part of my boot loader, which may be confusing. here I wrote another boot loader in the 16-bit real-time mode of the tiny version. Let's take a look.Here I will explain again that this article only records my own 16-bit OS experience and is no standard tutorial. however, I will not end

PHP's MD5-encrypted 16-bit and 32-bit implementation code has been found by many people on the Internet. it is correct to find a solution and record it.
The code is as follows:
Echo substr (md5 ("admin"), 8, 16); // 16-bit MD5 encryptionEcho "";Echo md5 ("admin"); // 32-bit MD5 encryption?>
The 16-bit MD5 encrypti
The first thing to declare is that this 4-digit (16) color map is special, rather than a 16-color map, it's just a gray-scale map that uses 4-digit 16 colors for simulation.
What is a grayscale image?
A grayscale image is an image that only contains brightness information without color information. As we usually see, the brightness changes continuously from dark
Problem
There is an emoji expression in IOS. Many machines cannot display this expression normally. I am determined to study this problem. I have referenced the following points:
1. Tools for converting strings into Unicode and UTF-8. Click to download
2. Click to open Wikipedia UTF-16
3. Click here for the introduction of the author's blog article UTF-8
For example, enter an emoji smile in the input box and check its encoding:
We can see that Unicod
offset (IP register is called instruction Register) he is representing the position of the next instruction to be determined by the offset of the CS segment Register + IPFor example, we have a code for assembly.The execution location of the next instruction is 0100 IP equals 0100 and can be viewed with the P command. In fact, IP equals 0100 is the IP offset is 0100, with CS segment register * + IP offset, is equal to the actual physical address (that is, the location of the next specified instr
Java 16 binary conversion integer.tohexstring () keyword: integer.tohexstring
To display the encoding for a byte-byte hexadecimal (two-bit hexadecimal representation), use:
integer.tohexstring ((Bytevar 0x000000ff) | 0xffffff00). SUBSTRING (6)
The effect of Bytevar 0X000000FF is that if Bytevar is a negative number, the preceding 24 zeros are cleared, and positive byte integers are unaffected. (...) | The 0xffffff00 effect is that if the Bytevar is

In the previous log (link), we discussed the Utf-8 encoding and GBK encoding conversion between the garbled problem, this article we discuss the Unicode (UTF-16 encoding) and GBK encoding conversion between the garbled problem. In the notepad that comes with the Windows system, we save using Unicode encoding as shown in the figure. In Visual Studio 2005, click File | Advanced save options to select unicode-code page 1200. Only garbled and ASCII code
Java in the transformation of the system there are many ways, which for the common basic binary Octal decimal 16 conversion, such as the implementation of the wrapper class, do not need to go through the two algorithm to implement, specifically as follows:
The first method for the simplest binary conversion is:

There are many friends for the first time using 16-bit color display will encounter how to convert 24-bit RGB color to the corresponding 16-bit RGB color problem, through the relevant information, write a translation of the principle of it, I hope it will be helpful to everyone.We know that 24-bit RGB is made up of 8-bit red, 8-bit green, and 8-bit blue, respectively:rrrrrrrr GGGGGGGG bbbbbbbbFor example, t
Copy CodeThe code is as follows:
Echo substr (MD5 ("admin"), 8,16); 16-bit MD5 encryption
echo "";

The 16-bit MD5 encryption uses the SUBSTR function to intercept the characters to be implemented ....
