- The secret to improving Linux RPM package installation speed
- This article gives you several tips to improve the installation speed of Linux RPM, eight key points, an independent and practical Linux training institution, to help you handle RPM software packages freely and become an operating system master. 1. Use the `yum` command to install RPM packages. First, let’s take a look at yum, a very practical software management tool in the Linux operating system. With the easy-to-use `yum' command, users can easily complete the installation, update and uninstallation of RPM software packages. For example, with the linuxrpm installation command, you only need to enter the following command to successfully install the RPM software package "package.rpm"! ```yuminstallpackage.rpm2.Specify installation

- Algorithm - Skip Search
- For example, suppose we have an array arr[] of size n and block (to be jumped) of size m. Then we search the indices arr[0], arr[m], arr[2m]....arr[km] and so on. Once we find the interval (arr[km] we consider the following array: (0,1,1,2,3,5,8,13,21,34,55,89,144,233,377,610). The length of the array is 16. Jump search will be as follows Column steps find 55, assuming the block size to be skipped is 4. Step 1: Jump from index 0 to index 4; Step 2: Jump from index 4 to index 8; Step 3: Jump from index 8 to index 16 ;Step 4: Since the element at index 16 is greater than 55

- Use coredumpctl to find and fix bugs
- It's an unfortunate fact that all software has bugs, and some bugs can cause your system to crash. When it occurs, it often leaves a data file on disk called a "core dump." This file contains relevant data about when your system crashed and may help determine why the crash occurred. Often developers ask for data in the form of a "traceback" showing the flow of instructions that led to the crash. Developers can use it to fix bugs to improve the system. If your system crashes, here's how to easily generate a traceback. Starting with using coredumpctl Most Fedora systems use the Automatic Error Reporting Tool (ABRT) [1] to automatically capture crash files and log bugs. However, if you disable this

- A must-read for Linux newbies: Easily configure Fcitx input method and say goodbye to native input troubles
- As a professional who loves computing science and is good at IT engineering, I have deep feelings for the Linux operating system. Recently, I migrated from Windows to Linux without any hesitation. However, I found that the input method that comes with native Linux is not satisfactory, so I decided to install a more convenient input method for it. Although the process was not easy, in the end, I was successful in making this change. 1. Find a suitable input method Dear Chinese users, if you are looking for a faster and smoother Chinese input solution on Linux, please consider using the Fcitx input method. After comparing the actual experience with other options, I hope it will become your first choice. Dear user, to set the default gateway in Linux, please visit the official website, we

- Algorithm - Russian multiplication
- Non-mainstream algorithm for multiplying two positive integers Assume n and m are two positive integers, calculate n*m, and now use the input of n as a measure of instance size. Assuming n is an even number, an instance with half the original size must process n/2, n*m=n/2*2m Assuming n is an odd number, only a simple adjustment of the formula is required, n*m=(n- 1)/2*2m and use 1*m=m as the termination condition. If we write down an example, we will find that when the current value of n is an odd number, we only need to add the corresponding m value to get the product of n*m. For example: 50*65=25*130=12*260 (+130)=6*520=3*1040=1*2080===2080+1040+

- Overcoming obstacles: Solving GRUB and SHIM problems during Linux system startup
- As a Linux user, you will inevitably encounter various problems during the startup process. Among them, the two tools GRUB and SHIM are often the most likely to cause problems. GRUB is the GNU boot loader, and SHIM is a trusted boot (SecureBoot) solution. The two work together in the Linux system startup process, but they also make some users confused and distressed. This article will introduce you how to solve GRUB and SHIM problems during Linux system startup, allowing you to easily overcome these obstacles. When using the efibootmgr-v command to modify the efi startup item, I don’t know whether to choose GRUBX64.EFI or SHIMX64.EFI when specifying the boot program.

- Master teaches you how to check your time zone in Linux
- In this short article, we will briefly introduce you to several simple methods to check the system time zone under Linux. Time management skills in Linux machines, especially on production servers, are an extremely important aspect of system administration. Linux contains a variety of time management tools available, such as date or timedatectlcommands. You can use them to obtain the current system time zone, or you can synchronize the system time with an NTP server to automatically and more accurately manage time. Okay, let’s look at a few different ways to check the time zone of our Linux system. 1. We start by using the traditional date command and use the following command to take a look at our current time zone: $date or

- You can try to use the following solutions to intercept Linux kernel functions
- You can try to use the following solutions to intercept Linux kernel functions: Using Linux Security API From a best practice perspective, we feel that using the hook function of Linux Security API is the best choice, because this socket is designed for this purpose . Key points in the kernel code include security function calls, which may cause the installation of security modules to escalate. This module can study the context of a specific operation and decide whether to allow or prohibit it. Unfortunately, the LinuxSecurityAPI has two major limitations: the fact that kernel developers have different ideas about whether a system can contain multiple security modules, and the fact that modules fail to be dynamically loaded is certainly
