Ecosystem partner o1Labs has announced the latest stable node release, 2.0.0! This release is the first phase of Mina’s upcoming mainnet upgrade, and will formally begin the upgrade process. If you’re operating a node on Mina, you should upgrade to this version immediately! Find the full release notes in GitHub here: https://lnkd.in/eRnH4zUc The upgrade is set to bring three key features to the network: Easier zkApp programmability A more powerful proof system Removal of Supercharged Rewards Read more about what the upgrade will bring to Mina Protocol in this blog post: https://lnkd.in/e7wmgD5f

Something to know more about node and operating system!

I just published an article that covers Docker installation and configuration for daily use, specifically for users in regions with strict internet controls. If this doesn't apply to you, feel free to skip it.

Building L7 Load balancer from scratch in Go 🚦 I once heard that student majoring computer science should built their own operating system... I started with the idea of making an LB, if not an operating system, at least an LB. Building an LB required some knowledge about various domains including several LB algorithm(RR, Ring hash, Maglev, etc), Go standard net/http library, Concurrency(atomic operations, RW mutexes), and so on. My first goal was to support Yorkie backends, which currently managed by Istio/Envoy LB with resolving so called split-brain issue of long-lived connections(gRPC, Websockets) when backend changes on ring hash based LB. I have now built an LB with maglev consistent hashing algorithm and mechanism to forcefully close connection on split-brain issue. The main idea was to store connection with key-hash value, then recalculate them on backend changes. This is the repo for my LB: https://lnkd.in/g-RvwygV #loadbalancer #Go #Maglev

Load Balancers are a crucial part of modern software as they make you sleep rest assured not worrying about usage hotspots! So in this Coding Challenges's challenge I built a simple, concurrent, layer 7 load balancer written in Golang. No 3rd party dependencies, only standard library. You can hook up any number of servers you want, and the load balancer will handle request redirect, healthy and down servers check for you.

Scanning local networks sometimes can be challenging if you do not have enough permissions to install tools etc. I wrote two seperated but same goaled scripts for scanning specified IPv4 Blocks with using Gemini Advanced. You can even get the results with a "output.txt" which includes IP's MAC's and Vendors (if found). You can read more from my repo https://lnkd.in/dNfiEJ8b

Node.js v22.9.0 is a key update! Improved debugging, faster performance, and stronger security features make this release a must for developers. #Nodejs #JavaScript #WebDev #Security

How does a TCP server efficiently manage concurrent client connections? ⚡ I was exploring the internals of TCP and reverse proxies, and what better way to understand these concepts than by going hands-on? I created my own TCP server and reverse proxy from scratch. I have touched upon - Building a TCP server that can handle multiple concurrent requests. - Implementing a reverse proxy to efficiently route client requests to the backend. - Utilizing goroutines in Go for concurrency and performance. - Managing real-time communication between clients and servers.

I keep it no fluff; just engineering. #golang #networkprogramming #TCP
