Every time I open a terminal on macOS, zsh takes like a second to show the
prompt. It’s super annoying!

So, I’ve just disabled:
I’m diving headfirst into using uv in my daily grind to be more efficient in
my pile of work. So, I’m throwing myself into all sorts of random scenarios.
On this journey, I’ve stumbled upon some [bugs][uv-bug] and nifty features like
a super-powered cache. But, hold up! The real point of this post is how an
innovation affects to the production process.
I’m sure you’ve found yourself needing to do quick calculations in the
terminal. Sure, you could use a calculator app or a fancy spotlight bar, but
sometimes the calculation is so simple that typing it directly would be easier.
Wouldn’t it be nice if you could just type math "200 ** 2 / 200" and get your
answer right away?
I’ve found an issue with uv while creating a simple venv. Nothing fancy
with my dependencies. I’ve condensed everything in this issue:
But here is the minimal reproducible example of it:
1

4

rm -rf test
uv init test
cd test
uv version
# uv venv && uv pip install numpy statsforecast
uv add numpy statsforecast
For the time being, I’m using the latest release.
Hey there! 👋
This is a revisited version of my previous post about Makefiles, but this time
I’m using uv (the shiny new Python package manager that’s faster than a
caffeinated cheetah! 🐆).
I was tired of typing the same commands over and over in my Python projects, so
I made this super cool Makefile using uv.

Vim Let’s explore a few different ways to run commands in our terminal from
the comfort of neovim. Trust me, it’s cooler than it sounds! 😎

Hands-on Hey! This is my absolute favorite command ever! I use it all the time when I’m
writing docs or README files because, let’s face it - who wants to manually
copy-paste code outputs? Not me! 😅 Instead of doing things the boring way, I
use this neat little trick to get things done quickly. Plus, it’s super handy
when you want to format text using other tools too like sql queries!
Let’s dive into the world of Docker Compose and environment variables, where
hilarity ensues and variables come alive (or do they?).
We’ve all been there. Playing hide and seek with environment variables in
Docker Compose. Let’s see how our dear friend MYVAR enjoys this grand game of
Peekaboo!
