- 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

- SEI currency has surged fourfold in the past two weeks. What is the reason? What other potential opportunities are there for the Sei platform?
- People are looking for the next Solana, and Sei is considered to have the best chance of becoming its potential stock. Recently, the price increase of Sei's native token SEI has been eye-catching. Yesterday, SEI broke through a record high, reaching $0.8, an increase of nearly four times in two weeks. The community can't help but wonder, since the airdrops have not given much and the currency price has been tepid, why did Sei become so popular at the beginning of 2024? Why does SEI currency rise? Parallel EVM Narrative On August 15, 2023, the Sei mainnet was officially launched. Subsequently, on November 29, Sei released the V2 strategic plan. According to the official statement, Sei previously used Cosmwasm smart contracts written in Rust, but as Sei attracted more developers, in order to provide higher flexibility

- Steps to write a simple neural network using Rust
- Rust is a systems-level programming language focused on safety, performance, and concurrency. It aims to provide a safe and reliable programming language suitable for scenarios such as operating systems, network applications, and embedded systems. Rust's security comes primarily from two aspects: the ownership system and the borrow checker. The ownership system enables the compiler to check code for memory errors at compile time, thus avoiding common memory safety issues. By forcing checking of variable ownership transfers at compile time, Rust ensures that memory resources are properly managed and released. The borrow checker analyzes the life cycle of the variable to ensure that the same variable will not be accessed by multiple threads at the same time, thereby avoiding common concurrency security issues. By combining these two mechanisms, Rust is able to provide
