🚀 Why Anthropic’s MCP Is a Big Deal AI models today can reason - but they can’t reliably act.  Once trained, they lose access to real-time data, APIs, and tools. Anthropic’s Model Context Protocol (MCP) aims to fix that. It’s a universal connector for AI - a shared standard that lets models talk to databases, APIs, and other systems safely. MCP standardizes communication between AI and external tools - much like how USB or HTTP unified earlier eras of computing. Three key parts: the Host (AI app), Client (translator), and Server (data bridge). Together, they let models access live information and take real-world actions. Open by design: Anthropic released MCP as open source to encourage broad adoption and prevent fragmentation across AI systems. Why it matters: This could turn today’s static models into connected agents that interact with live data - powering the next generation of AI assistants and workflows. 🔗 Read the full breakdown: https://lnkd.in/e_dXj28N Supported by our partners building tools that help developers move faster: Sentry - AI Code Review that catches issues before they ship: http://bit.ly/43w8iGo Conduktor - Helping teams avoid costly Kafka pitfalls at scale: https://bit.ly/4qCz5Ll

How does Git work?    To begin with, it's essential to identify where our code is stored. The common assumption is that there are only two locations - one on a remote server like Github and the other on our local machine. However, this isn't entirely accurate. Git maintains three local storages on our machine, which means that our code can be found in four places:    - Working directory: where we edit files  - Staging area: a temporary location where files are kept for the next commit  - Local repository: contains the code that has been committed  - Remote repository: the remote server that stores the code    Most Git commands primarily move files between these four locations.    Over to you: Do you know which storage location the "git tag" command operates on? This command can add annotations to a commit. -- We just launched the all-in-one tech interview prep platform, covering coding, system design, OOD, and machine learning. Launch sale: 50% off.

What happens when you type a URL into a browser? Let’s look at the process step by step. Step 1: The user enters a URL (bytebytego .com) into the browser and hits Enter. The first thing we need to do is to translate the URL to an IP address. The mapping is usually stored in a cache, so the browser looks for the IP address in multiple layers of cache: the browser cache, OS cache, local cache, and ISP cache. If the browser couldn’t find the mapping in the cache, it will ask the DNS (Domain Name System) resolver to resolve it. Step 2: If the IP address cannot be found at any of the caches, the browser goes to DNS servers to do a recursive DNS lookup until the IP address is found. Step 3: Now that we have the IP address of the server, the browser sends an HTTP request to the server. For secure access of server resources, we should always use HTTPS. It first establishes a TCP connection with the server via TCP 3-way handshake. Then it sends the public key to the client. The client uses the public key to encrypt the session key and sends to the server. The server uses the private key to decrypt the session key. The client and server can now exchange encrypted data using the session key. Step 4: The server processes the request and sends back the response. For a successful response, the status code is 200. There are 3 parts in the response: HTML, CSS and Javascript. The browser parses HTML and generates DOM tree. It also parses CSS and generates CSSOM tree. It then combines DOM tree and CSSOM tree to render tree. The browser renders the content and display to the user. -- We just launched the all-in-one tech interview prep platform, covering coding, system design, OOD, and machine learning.

7 Years, 8 Books, 1 Launch. A lot more to come! Launching the All-in-one interview prep. 7 years ago, I quit my last job at Twitter. I had no idea what to do next. For some random reason, I spent 1.5 years writing the first System Design Interview book. People liked it, so I found a co-author and we wrote System Design Interview – Volume 2 together. People seemed to like that too, so I decided to collaborate with more amazing authors. One after another, we’ve successfully published 7 Amazon bestsellers, with more on the way this year. It’s been a wonderful journey, and I could never have imagined we’d come this far. Everyone says books don’t make money, but sometimes, certain things are worth more than just money. And I’m grateful we were also able to figure out a business model along the way. We could never have reached this point without all the amazing people who supported us. For that, I want to say. Thank you from the bottom of my heart ❤️ Today, we’re making all the books available on the ByteByteGo website. Launch sale: 50% off.
