  How to find which process a file is being written by in Linux?

Some people ask a file is being written by one process and they want to check this process, but they cannot find the process even with sof. This question is very common and there are many solutions, here we introduce a straightforward method. In Linux, each file will be stored on one device and of course there will be a relative inode, then we can use vfs.write to know who is writing the inode on one specified device continuously. Luckily there is inodewatch.stp in the installation package of s...

  Why Most of us Get Confuse With Data Quality Solutions and Bad Data?

How to fix this misunderstanding is what Big Data professionals will explain in this post. The C-level executives are using data collected by their BI and analytics initiatives to make strategic decisions to offer the company a competitive advantage. The case gets worse if the data is inaccurate or incorrect. It’s because the big data helps the company to make big bets, and it impacts the direction and future together. Bad Data can yield inappropriate results and losses. Some interesting ...

  Difference between localhost and 127.0.0.1

Lots of people would think what the address 127.0.0.1 is when first seeing this address. In fact, 127.0.0.1 is a loopback address which refers to the local machine. It is generally used for local testing. When typing ping 127.0.0.1 on local command console, it will send network packets to local IP/TCP layer to test whether IP/TCP works properly or not.  To those who are used to use localhost, it is actually mapped to 127.0.0.1 by default. There are hosts files in the system which store this...

  The Go Pointer Magic

Go is a language with the pointer type, by which we can Pass pointer into a function and update value in-place. Add methods to a struct as (* T) A, which is different from (T) A(). However, the pointer is type-safe in Go, meaning that there are such restrictions of the pointer. Different types of pointers are unconvertible. Pointer type cannot be used for calculation. Pointer types cannot be compared, either == nor !=. No mutual assignment between different pointer-...

  Private LLM Integration with RAGFlow: A Step-by-Step Guide

If you’ve found your way here, you’re probably already excited about the potential of the RAGFlow project and eager to see it in action. I was in the same position, so I delved into the codebase to see how it could work with custom large language models (LLMs). This post will walk you through my findings and show you how to get RAGFlow running with your own LLM. As of now (November 8, 2024), RAGFlow offers limited support for local LLMs, and vLLM&nb...

  Introduction to GoLang generics and advanced usage

Generics in Go allow you to write code that can work with multiple types of data, without having to write separate versions of the code for each type. This can make your code more flexible and easier to maintain, as you only need to write and test the code once, rather than maintaining multiple versions. To use generics in Go, you first need to define a type parameter, which is a placeholder for the type that the code will work with. For example, you might define a type parameter called "T" like...

  Secure Your Go Code With Vulnerability Check Tool

Security vulnerabilities exist in any language and any code, some are written by ourselves, but more are from the upstream dependencies, even the underlying Linux. We have discussed the security protection methods for Go and Kubernetes Image in Path to a Perfect Go Dockerfile and Image Vulnerability Scanning for Optimal Kubernetes Security, in which the security scanning was performed based on generic. As the Go community grows, more and more open-source packages have caused ...

  Understanding Cursor and WindSurf's Code Indexing Logic

Background: The Importance of Context in AI Programming If the “intelligence” of large models, such as Claude 3.5 Sonnet, is the key factor driving a stepwise leap in AI programming capabilities, the other critical factor is the context length. Currently, Claude 3.5 Sonnet offers a maximum context length of 200k tokens. While this is more than sufficient for conversational models—capable of handling a 50,000 or even 100,000-word book with ease—it still falls far short for...
