- The Linux terminal command line can also be used to view images
- There are a large number of GUI applications available for viewing images in Linux. To be honest, I haven't used any command line application that displays pictures in the terminal itself. Luckily I found 2 command line image viewers to display images in the terminal. These applications may be useful for those who want to use a CLI alternative for GUI applications and spend most of their time in Terminal. 1. Display images in the terminal using Viu Viu is a command line application for viewing images from the terminal. It is a free and open source CLI image viewer written in the Rust programming language. Using Viu we can; display popular image types including .jpg, .png, igif and more. in custom size

- Make your Linux file management easier - upgrade to exa tool
- In Linux systems, file management is a very important operation, but the traditional ls command cannot meet the user's needs for file list display. At this time, a more powerful and easy-to-use tool is needed. Today, we will introduce a tool called exa, which can make your Linux file management simpler and more efficient. Introduction to the exa command exa is a command line tool that can list directories and files in the specified path (if not specified, the current directory). This may sound familiar because that's what the ls command does. exa is seen as a modern replacement for the ancient ls command from the old days of UNIX. As claimed, it has more features and better default behavior than the ls command

- How to use Linux commands to clear hard drive space and give your system a new lease of life
- In the process of using Linux systems, we often encounter insufficient disk space. When there is insufficient disk space, the system will run extremely slowly or even crash. Using Linux commands to clear hard disk space is a very simple and effective method that can give your system a new lease of life. In this article, we will introduce several commonly used Linux commands to help you clear hard drive space and improve system performance and stability. If you work on the Linux command line, you should be familiar with the du command. Understanding commands like du, which can quickly return information about disk usage, is one of the ways the command line can improve programmer productivity. However, if you are looking for a way to save more time and make your life

- Does Go provide a standard or de facto way to handle errors within a single statement (i.e. inline error handling)?
- In Rust, the Result type can be thought of as the (val,err) pattern in Go, which can be "unrolled" immediately in the statement in which it appears, and does not require the complexity of dedicating multiple lines to this task. For example, suppose we have a function foo that returns a number or an error. In Rust, handling this error (without ignoring it) can be as simple as: letx=foo().unwrap()+1; in Go, the recommended approach seems to be: x,err:=Foo()iferr!=nil {panic(err)}x=x+1Does Go provide a

- Convert big.Int to int64 and vice versa as well as two's complement
- I'm trying to convert gobig.int, which represents a 128-bit integer, to [2]int64. The idea is to be able to match Rust's i128::to_le_bytes(), which encodes 128-bit signed integers into little-endian byte order. This example matches rust's i128::to_le_bytes(). Whenever I try to convert it back to big.int I don't get the same value. Are any bits lost when doing the initial right shift? Thanks. packagemainimport("encoding/binary""fmt""mat

- dutree: A powerful Linux file system disk usage tracking tool
- dutree is a fast, open source command line tool for analyzing disk usage. It is written in the Rust programming language and combines the functionality of the durep (disk usage reporting tool) and tree (listing directory contents in a tree format) command line tools. Therefore, dutree is able to report disk usage in a tree format. As a powerful disk usage tracking tool, dutree is suitable for Linux file systems. It is free and open source and is able to display results in the form of colored output, with the color depending on the configuration of the GNULS_COLORS environment variable. This environment variable allows setting the color of files based on their extension, permissions, and type. dutree has the following characteristics:

- The best whiteboard apps on Linux
- "We will introduce several whiteboard applications for Linux systems. I believe this information will be very helpful to you. Please continue reading!" Generally speaking, a digital whiteboard is a tool for large-scale interactive display panels. Common Device types include tablets, large-screen mobile phones, touch laptops, and surface display devices. When teachers use a whiteboard, you can use a stylus, stylus, finger, or even a mouse to draw, write, or manipulate elements on the device screen. This means you can drag, click, delete, and draw on the whiteboard just like you would with a pen on paper. However, to achieve all this requires a software to support these functions and achieve fine coordination between touch and display. There are many commercial applications on the market that can do this job.

- What is Layer2? What other leading projects are there for Layer 2?
- Summary There are two expansion routes for Ethereum: on-chain expansion and off-chain expansion. On-chain capacity expansion mainly uses sharding technology, but due to the difficulty of development, its development has been slow. Relatively speaking, off-chain expansion solutions mainly refer to Layer 2, which is easier to implement. With the rapid development of applications such as DeFi, the need for capacity expansion has become urgent, so the market is currently paying more attention to Layer 2 solutions. Among the many Layer2 solutions, OptimisticRollup and ZKRollup are highly favored by the market. These two solutions achieve off-chain expansion through different mechanisms, improving Ethereum’s throughput and transaction speed, while maintaining the security and decentralization features of the chain. OptimisticRollup batches transactions

- Interpretation of dynamic NFT: in-depth exploration of its development prospects and possibilities
- Since last year, the term NFT has become a topic of global concern. Different from traditional NFT, dynamic NFT, as one of its branches, has attracted much attention due to its interactivity and changeable elements. These characteristics bring more innovation and value applications to it, making it a hot topic among enterprises. What is dynamic NFT? First of all, the main advantage of dynamic NFT is its high degree of variability and scalability. Compared with static NFT, it can display more elements, such as animation, sound and interactive images, and can produce metadata changes based on changes in time or conditions. For example, a dynamic NFT artwork can show different styles or express different emotions at different points in time. Likewise, a dynamic NFT

- Rust is a popular choice for software refactoring, and FreeBSD is also considering its integration
- In recent years, the trend of refactoring the Rust language has swept the development circle. Rust has received widespread attention for its advantages in safety, efficiency, and maintainability. Even the Windows and Linux kernels have introduced Rust support. This makes Rust one of the most popular programming languages among developers. FreeBSD developers are also currently weighing the pros and cons of using the Rust programming language in their base systems. According to the latest email message from the developers, the main disadvantage of including Rust in the FreeBSD base system is that the build time is doubled. Due to the need to compile the LLVM-based Rustc compiler and all the additional features of Rust, the system's build time will be approximately twice as long as it currently is. However, developers
