  Simplify Cloud Data Security: A Deep Dive Into Protecting Sensitive Data in Java

Featuring encryption, anonymization, hashing, and access control Network security incidents occur now and then, mostly caused by data leakage. Data security has aroused widespread concern, and the community keeps working hard on approaches to simplify data security, especially in sensitive data protection. Sensitive data includes but is not limited to personally identifiable information (PII) like names, ID numbers, passport numbers, driver’s license numbers, contact information like addre...

  How Query Optimizer Works in RDBMS

In a previous post, we discussed how the various relational operators are implemented in relational database systems. If you have read that post, you probably still remember that there are a few alternative implementations for every operator. Thus, how should RDBMS determine which algorithm (or implementation) to use? Obviously, to optimize the performance for any query, RDBMS has to select the correct the algorithm based on the query. It would not be desirable to always use the same algori...

  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 ...

  Tips of Drafting an R Markdown Document

When presenting the data summary and exploratory analysis, we used to copy a lot of tables, charts from Rstudio to PowerPoint, which makes the presentation preparation painful. It becomes essential for data scientists to make use of better reporting tools, such as R markdown, Jupyter notebook to prepare the analysis presentation in a more efficient and organized way. Of course, we want this to be reproducible! In this post, I would like to share some tips of using the right tools to draw tables,...

  9 reasons to use Zsh

Like majority *nix users, I have been using bash for many years. Sometimes I feel uncomfortable with bash. I tried use some other shells as well such as ksh, tcsh and zsh which I am going to talk about. A few days ago, I found an open source project ranking in the 6th named oh-my-zsh on Github, I downloaded it and had a try with it. It's amazing. We should use zsh to replace bash now. Why do we need to use zsh? Here is a 4 minutes YouTube video which shows many reasons why we should switch from ...

  Understand JavaScript prototype

For an front end programming language like JavaScript, if we want to understand its OOP feature, we need to understand its objects, prototype chain, execution context, closure and this keyword in deep. If you have a good understanding on these concepts, you should be confident that you can handle this language well. The inheritance in JavaScript is not class inheritance like Java, but it adopts another mechanism-- prototype inheritance. The key to prototype inheritance is the prototype chain mec...

  Deep Understanding of ReentrantLock: Unlocking the Mysteries of Java Concurrent Programming

ReentrantLock introduction ReentrantLock is a class in the Java concurrent package, java.util.concurrent.locks, and is an implementation of the Lock interface. As its name suggests, it is a reentrant mutual exclusion lock. A mutual exclusion lock is a synchronization tool used to protect shared resources, ensuring that only one thread can access the resource at a given time. Reentrant means that a thread can acquire the same lock multiple times without causing a deadlock. This lock provides some...

  Do Not Be Misled by ‘Build an App in 5 Minutes’: In-Depth Practice with Cursor

In August this year, I tried out Cursor and was thoroughly impressed, prompting me to write an introductory article about it. Soon after, I transitioned my daily work environment entirely from GitHub Copilot + JetBrains to the paid version of Cursor. After several months of use, it has felt incredibly smooth. While using it myself, I’ve often recommended Cursor to colleagues and friends. However, many of them still have questions, such as: What advantages does it have over native ChatGPT ...
