The server will not be able to display the disk after the shutdown is restarted (one can and one cannot be identified) after confirming that the disk is not damaged (hardware is not damaged) considered a server kernel upgrade, resulting in incompatible kernel and hardware (this disk) Workaround: demote the server kernel. 0 View existing kernel versions sudo dpkg--get-selections |grep linux-image 1 Install the kernel version you need sudo apt-get install Linux-image-4.4.0-75-generic 2 Uninstall

In the PC that controls the robot, when the embedded system starts, the ROS program is often required to boot up. The SAM has tried several methods and is now logged as follows: 1. Ros Official method: Robot_upstart:the Robot_upstart package provides scripts which may be used Toinstall and uninstall Ubuntu Lin UX upstart jobs which launch groupsof roslaunch files. Therefore, this method may only support Ubuntu Linux. It provides scripte to install and

Good programming principles are closely linked to good system design principles and technical implementation principles. The following programming principles have made me a good programmer in the past years, and I believe that these principles can greatly improve the programming capabilities of any developer, allowing him to develop programs that are more maintainable and less flawed.　　I don't want to repeat myself -this is probably one of the most basic tenets of programming development, which

0. Write in frontFor the first contact with the Linux system, the installation of ns-3 seems unfriendly. But in fact, the installation process is not as complicated as it seems to be in a methodical way. In this paper, the installation process in the official Wiki is slightly combed, hoping to bring some convenience for beginners. As the description in the official Wiki is sufficiently detailed, there will

Now many friends have their own blog page, although they may not want to go to the wood to write a personal diary of the way, but to highlight the personality, publicity of the purpose of the ego, mostly similar. In fact, at this time, many of China's technology fans have looked to the wiki. After the network anti-Huang and Miko Mi, China's netizens have been familiar with the blog. As a new network concept, with the support of sophisticated technolog

Previously, moinmoin1_topedition was installed in Windows XP as its local Wiki (using MoinMoin desktop edition as a personal local knowledge accumulation tool). Because Ubuntu and Winxp systems are used, it is hoped that the two systems share the same wiki program without data synchronization, which will cause trouble for Data Query and save the maintenance of data synchronization. MoinMoin does not require

Original article: team collaboration with GitHub GitHub has become the cornerstone of all open source software. Developers like it, collaborate based on it, and constantly develop amazing projects through it. Except ?? Code hosting, GitHub's main attraction is to use it as a collaborative development tool. In this tutorial, let's take a look at some of the most useful GitHub functions, especially those that make the team work more efficient, more productive, and very important and fun! GitHub a

A good programmer generally consists of four aspects: Operation Skills, Knowledge Level, experience layer and ability. I would like to share with you some of the principles in design. I think these things are lessons learned from long-term experience. Every programmer should understand these principles. However, we recommend that you do not adopt dogmatism. You must consider the actual situation when using it. In fact,The following principles can not only be applied to software development, but

As a non-profit organization, the Wikimedia Foundation can donate money to sustain its own development. As a concept of "wiki". I don't know what it was like when Wales made the big decision not to publish commercials on Wikipedia, even when we were speculating with malice, perhaps Wales w

In versions earlier than centos 7, the system running level is defined through the/etc/inittab file: [[emailprotected] ~]$ cat /etc/centos-release CentOS release 6.4 (Final)[[emailprotected] ~]$ cat /etc/inittab # inittab is only used by upstart for the default runlevel.## ADDING OTHER CONFIGURATION HERE WILL HAVE NO EFFECT ON YOUR SYSTEM.## System initialization is started by /etc/init/rcS.conf## Individual runlevels are started by /etc/init/rc.conf#

Modify the default running level of CentOS, disable Linux [1], and modify the default running level. By default, only the command line interface is enabled, saving the following resources: Modify the default startup level in the inittab file, change from 5 to 3. (Note: Do not set the default running level to 0 or 6) the meaning of each start level of www.2cto.com is as follows: 0 is stopped, and the machine is disabled. The single-user mode is similar to the security mode in Win9x. 2-user mode,
