Ever wanted to search the web without leaving your Linux terminal? The ddgr program lets you do just that using the DuckDuckGo search engine.

What Is ddgr?

ddgr is a command-line tool that lets you search DuckDuckGo, the privacy-respecting alternative to Google. DuckDuckGo sources its data from Bing and other sources, to provide excellent results.Once you run a search in ddgr, you’ll see a list of results with the most important information in each: URL, title, and description. You can then use the interactive interface to open any of these results in your browser.If you’re a big fan of the terminal, you’ll be spending a lot of time in it, and ddgr provides a lot of convenience.

ddgr prominently displays the domain of each result, so you can focus on the source. But you can configure the tool to show full URLs, and change its behavior in many other ways.

A static IP address assigns a fixed address to your device on a network, unlike a dynamic IP that changes over time. Static IPs are essential for servers, network printers, or any device requiring reliable access, such as for SSH, hosting, or database connections. Setting up a static IP ensures consistent connectivity and avoids IP conflicts in a dynamic environment.

What is a Bitcoin Mining Node and why set it up on Linux?

A Bitcoin mining node is a server that participates in the mining process by verifying and adding new transactions to the blockchain. Unlike a regular Bitcoin full node, a mining node also solves cryptographic puzzles to compete for block rewards. Setting up a mining node on Linux allows you to contribute to Bitcoin’s security while potentially earning Bitcoin rewards.

Running a mining node on Linux is ideal for advanced users who want to explore Bitcoin mining or participate in a pool. While solo mining is resource-intensive, joining a mining pool can make mining more accessible by pooling computational power with others. This setup provides deeper engagement with Bitcoin’s consensus mechanism and supports its decentralized infrastructure.

The Bitcoin Lightning Network is a second-layer solution designed to facilitate faster and cheaper Bitcoin transactions by processing them off-chain. While Bitcoin Core ensures security and decentralization, it can be slow and costly for smaller, frequent transactions. A Lightning Node addresses this by creating payment channels that enable rapid transactions without waiting for block confirmations, improving Bitcoin’s scalability.

A Bitcoin Block Explorer is a tool that provides a user-friendly interface for viewing blockchain data such as transactions, blocks, and addresses. While public block explorers are widely available, using them can compromise your privacy as they may log your searches and activity. Setting up your own Bitcoin Block Explorer on a Linux server ensures that you can access blockchain data privately, directly from your own Bitcoin Core node.

By hosting your own block explorer, you maintain full control over your data, eliminate reliance on third-party services, and improve the decentralization of the Bitcoin ecosystem. It’s a valuable addition for anyone running a full node who wants to monitor transactions or learn more about blockchain data without compromising privacy.
