REAL "modern" alternatives to common tools?
"modern" in the sense with needed or simply QoL improvements that the "original" doesn't have. Like "eza" over "ls", "fd" over "find", "ripgrep" over coreutils "grep", "nix" over whatever is out there etc.. (Not a nix user so I might be wrong) And "sd" or "ruplacer" over "sed" Hence uutils and "rewrites" don't count, as it has no planned differences to GNU coreutils (and "rewritten in rust" isn't much for silly core CLI tools which don't do much to have problems; language doesn't count that m
How SSH Actually Works (Step-by-Step for Developers)
Most developers use SSH every day: ssh user@server …but very few know what’s actually happening under the hood. Let’s break it down 👇 🚀 1. TCP Connection Everything starts with a basic TCP connection between client and server. At this stage: No encryption yet Just a raw connection 🤝 2. Negotiation Phase The client and server exchange: SSH protocol versions Supported encryption algorithms Key exchange methods They agree on a secure configura...
The tiny twitch which wretch
Is Go a good language? (a can of worms opens and closes). No, I mean, for the end-user? It turned out that there is one stupid thing which was done odd at argument parsing which makes Go a 'snowflake' language. Single-dashed arguments. I presume there were some arguments from developers to allow back single-dash long args (-hello) instead of double-dash ones (--hello), but it's just made it... special. In a bad way. We accept tar madness (tar vxzf) out of grand-dad respect, and the same fo...

Why SSH Key Management Is Broken and How Certificates Fix It
If you manage more than a handful of servers, you already know the pain. Every new developer who joins the team needs their public key added to authorized_keys on every server they need access to. Someone leaves? Good luck remembering all the places their key was authorized. And let's not talk about the first time you SSH into a new server and have to decide whether to trust that host fingerprint you definitely didn't verify. SSH certificates solve all of this, and they've been baked into Op...
