Fixing xterm-ghostty: unknown terminal type Over SSH

Wed, 27 May 2026 13:10:00 +0000

If you use Ghostty as your terminal on macOS and SSH into remote Linux servers, you’ve probably seen this:

root@server:~# clear
'xterm-ghostty': unknown terminal type.

Or this:

missing or unsuitable terminal: xterm-ghostty

This happens to everyone who uses Ghostty with remote servers. Here’s why it happens and how to fix it properly.

Why this happens

Ghostty ships with its own terminfo entry called xterm-ghostty. When you open a terminal, Ghostty sets TERM=xterm-ghostty in your local shell. When you SSH into a remote server, that TERM value gets forwarded. The remote server then looks up xterm-ghostty in its terminfo database — and finds nothing, because xterm-ghostty is not in any standard Linux distribution yet.

Deploying WordPress with MySQL, Redis, and NGINX on Docker

Wed, 27 Mar 2024 11:53:41 +0000

WordPress is a popular content management system (CMS) that powers millions of websites worldwide. However, as your website grows, you may experience performance issues. To improve WordPress performance, you can use object caching, which stores frequently accessed data in memory, reducing the number of database queries.

Prerequisites:

Basic knowledge of Docker and Docker Compose
Docker & Docker Compose installed on your machine
A domain name or IP address pointing to your server

Why do we need better performance in WordPress?

Website performance is crucial for user experience and search engine optimization (SEO). A slow website can lead to a high bounce rate, meaning visitors leave your site without interacting. Additionally, search engines like Google consider website speed as a ranking factor.

Why You Should Use Vectorization Instead of Loops in Python?

Sun, 14 Jan 2024 02:08:48 +0000

I’ve often come across scenarios where efficiency and speed are of the essence, especially when dealing with large datasets or complex numerical computations. One technique that consistently proves its worth in such situations is vectorization.

I’ll explain why vectorization should be your go-to approach over traditional loops in Python, especially when dealing with array operations.

What is Vectorization in Python?

Vectorization, in the context of Python, refers to the use of optimized, pre-compiled functions that can operate on entire arrays or sequences of data at once, instead of processing each element individually. This is particularly effective when using libraries like NumPy, which is designed for efficient numerical computations.
