64位系统DOSBox下面nasm编译程序出现&Unable to open include file 'pm.inc'&的问题
& 最近换了64位系统,发现其实对于操作系统的开发人员来说,这真的不是个很好的选择。但是既来之,则安之,有问题,咱就解决它!
& & 以前在32位的cmd里面用nasm编译,NASM编译时报错:E:\Proj_OS\pmtest1.asm:6: fatal :unable to open include file 'pm.inc'
& & &原因:pmtest1.asm文件引用pm.inc的路径不正确
& & &如下,将引用路径改为pm.inc所在路径即可。&
& & %include &C:\OS_test\pm.inc& ; & &
& & &这次在DOSBox中模拟的时候发现,这样依旧会报错,找不到路径。纠结了半天,能试的办法都试了,还是不行。。。
& & &这时,突然,想到这是在DOSBox里面模拟的结果。之前通过&mount K C:\&命令将C盘挂载到了K,所以在源程序里面应该改为:&
& & %include &K:\OS_test\pm.inc& ;
& & 一试,果然Ok...开心啊!

就想控制台显示那样
远程SSH能打印不
ssh去运行当然可以看到标准输出,更标准的做法是用日志记录
我感觉使用日志要好一些
进入日志目录
ls //看一下有哪些日志
tail -f catalina.log
screen,支持ssh断掉后程序继续运行,只要应用在一些小程序上。
之前在服务器上跑过一些java程序,看日志能解决已经发生过的事件。但是我想看看现在程序走到哪一步了,log也支持控制台输出。最好的方法是既写日志,也打印出来,这样就能两全了。
最好使用log.debug的方式,即使你输出看完后忘了删除,log配置关闭debug后也不会有影响。而System.out如果你忘了删除,代码还是会执行的,多少浪费了资源
可以看到的。
但是尽量用日志输出,不要用System.out.println

服务器环境Get faster console output (System.out.println() replacement) - Real's Java How-to
Get faster console output (System.out.println() replacement)
If your program is doing a lot printing to the console using System.out.println() then
it is possible to get a good performance boost by using an alternative to
the console output.
By default, System.out.print() is only line-buffered and does a lot work related
to Unicode handling. Because of its small buffer size, System.out.println() is not well suited to
handle many repetitive outputs in a batch mode. Each line is flushed right away. If your output is mainly ASCII-based then by removing the
Unicode-related activities, the overall execution time will be better.
Consider this program :
import java.io.BufferedW
import java.io.FileD
import java.io.FileOutputS
import java.io.OutputStreamW
public class Test {
public static void main(String...args) throws Exception {
long start = System.currentTimeMillis();
for (int i = 0; i & 1000000; i++) {
System.out.print("abcdefghijk ");
System.out.print(String.valueOf(i));
System.out.print('\n');
System.err.println("Loop time: " +
(System.currentTimeMillis() - start));
The result is
>java Test >NUL
Loop time: 7000
Now, rewrite this program to use a 512-bytes buffer and
specify the ASCII as character-encoding to be used.
import java.io.BufferedW
import java.io.FileD
import java.io.FileOutputS
import java.io.OutputStreamW
public class Test {
public static void main(String...args) throws Exception {
BufferedWriter out = new BufferedWriter(new OutputStreamWriter(new
FileOutputStream(java.io.FileDescriptor.out), "ASCII"), 512);
long start = System.currentTimeMillis();
for (int i = 0; i & 1000000; i++) {
out.write("abcdefghijk ");
out.write(String.valueOf(i));
out.write('\n');
out.flush();
System.err.println("Loop time: " +
(System.currentTimeMillis() - start));
The result is
>java Test >NUL
Loop time: 672
Note that your result will vary depending on your machine/java version but the
performance gain should in the same magnitude.
