I have reposted my personal homepage from dianhu and paid high respect to the author. Jdk1.4:In Linux, swing in Java cannot display Chinese characters by default. There are many introductions on the Internet, but they do not seem to be very

Next, we will continue to discuss how to use pthread_cond_t to implement sem_t. Currently, the Linux kernel supports sem_t, but some old OS such as aix4 and earlier Solaris do not support semaphores. After all, semaphore is not included in the POSIX

Checks whether the Linux host runs xen. The principle is to read the cpuid to determine whether the xenSource codeThe following section checks whether xen is a C language.CodeTools/MISC/xen-detect.c, this code provides a good example of rewriting

Environment: CPU: AMD athlon64 X2 5200 + very old but supports hardware virtualization, very practical chipset: nforce. I don't know how many generations, but Linux does not support this kind of non-mainstream chipset, resulting in various

No, completely incorrect ======================================================== ========== rpm and Deb have nothing to do with KDE and gnome, KDE and gnome are desktop systems. Rpm and Deb are software package management systems. Any Linux release

The kernel module is an external plug-in provided by the Linux kernel. It is called the dynamic loadable kernel module (lkm. The Linux Kernel provides a module mechanism because it is a single kernel ). The biggest advantage of a single kernel is

This article continues the previous article and analyzes the workflow of DM-ioband through several typical scenarios. The first scenario Is Example 1 in the http://sourceforge.net/apps/trac/ioband/wiki/dm-ioband/man/examples, first call the command

In Windows, the physical address is separated first, and then a directory is created on the partition. in windows, all paths start with the drive letter, such as C: // program. File. the opposite is true for Linux, where a directory is first

First, we will introduce pthread_cond_t. In Linux, it is called a state variable. Related APIs are as follows:   Int pthread_cond_init (pthread_cond_t * cond, pthread_condattr_t * cond_attr );Int pthread_cond_signal (pthread_cond_t * Cond );Int

I read a bunch of RCU documents and concluded that the actual programming of this stuff is not used much, so we can entertain ourselves. Https://www.ibm.com/developerworks/cn/linux/l-rcu/ The Linux synchronization mechanism section in ldd3rd

Tso, the full name is TCP segmentation offload. We know that the MTU of Ethernet is 1500, except for the TCP/IP packet header, the size of tcp mss (max segment size) is 1460, generally, the protocol stack performs segmentation on TCP payload of more

I used the z301b USB camera of xingwei and ran it on the embedded board. I searched the information on the network for a long time and did it myself, but I still cannot, I don't have an arm base. I have been in touch with Linux for more than a week

The methods for modifying the Linux system time are summarized as follows: Note that the system time is maintained by the operating system in Linux.When the system is started, the Linux operating system reads the time from CMOS to the system time
