• You tried jupyter, and you tracked a bug for hours because you defined a variable twice with the same name
• You wanted to share your notebook with git, and had 5 merge conflicts in the same day
• You wanted to transform your notebook into a python script, to move it to production
• You dream about using SQL in your python notebooks
• You want to automatically re-run some cells depending on the result of others, or depending on you input like a slider

Zed

• Your laptop does not have the resources to run VScode with a decent speed
• You hate microsoft
• You want a vim-mode that works, and is deeply integrated with the editor
• You want a very, very, very fast editor. Seriously, it's hundreds of times faster than its competitors.
• You want a great default config to work with python, js, java, html, css, rust, go, markdown ... without having to install anything.

Yazi

• You spend a lot of time in your terminal, and you would like to display your markdown, pdf, jpeg, mp4 and svg in it (yes, it's possible)
  • 
• You often want to import some code / config file / text file from an older project, and you want to die when you try cp -r ../../../projects/2024/foobarbaz/src/module src and you realize it was not in THIS project but in the other one from 2023
• your file manager is just too slow, you know 🐌
• you want something as good as VIM, but for file management

Photoprism

• you are constantly trying to find a picture of a specific event, and you don't know who took the photo
• You love self-hosting things
• You hate how you're phone is syncing with your drives at random times, without asking your permissions
• You have multiple hard drives, and you would prefer t have a single one with all your photos.
• You travel a lot and you would like to see a map of where the photos were taken (not my case but it may be yours)

Syncthing

• you use some tool on at least 2 devices (a note taking app, music thing, or something else) and data is never up to date between the 2
• You don't like USB sticks / you don't have a USB stick compatible with your phone
• You want to have you administrative documents always with you, and edit them from your phone or computer

Grist

• You don't understand how people at Google or Microsoft are not smart enough to create a usable formula system
• You like the ability to share with Google Sheets, but don't like
• You are the kind of person who like to automate everything, and you would like to manage your surveys, your calendar, or even your mails in a spreadsheet
• You decided to use a database for a personal project, and now you have to remember this kind of syntax just to insert a value. Or worse: renaming a column
  • sql UPDATE posts SET url = REPLACE(url, 'http','https');
• You work with structured data (Coordinates, Dates) and you want to visualize them INSIDE the spreadsheet app.
• You start with a "commands" spreadsheet. You realize each command has a "user", so you create a new "user" table. Your bran start switching to SQL mode, and you cry all the tears of your body because Excel is just too dumb.

Typst

• LaTeX is heavy and hard to install. You have multiple ways to install it, most of them break at some point, it's huge (like more than 500M of files), I'm not sure you can't install it without sudo. In comparison, Typst is a single binary
• Since it's so hard to install, most LaTeX user use an online editor called Overleaf. It's a crappy editor to be honest, and it does not fix the second major problem of Latex: it's extremely slow to compile. Typst also has a web editor, but the compilation is in most case instant thank's to incremental compilation.
• LaTeX syntax is horrible. The most used character in Latex is \, which is hard to reach on a lot of keyboard. In typst, function are defined with #let function = and called with #function(). The escaping logic (an extremely important thing for preprocessors) is great.
• LaTeX syntax is slightly less awful for math, but sometimes can be confusing. In particular for things like \underbrace, \big or \begin{align}
• Packages ... From my understanding there is no such thing as a standard library for LaTeX, so depending on your installation method you will not have the same. And they're not really nice to install. In Typst: you have a fixed core, and packages you can install just by doing #import "@preview/cetz:0.4.2". And the documentation of any package you can imagine is accessible in the Typst universe
• Typst has a super cool Turing-complete scripting language. You can do what you want with it.

Just

• You are constantly looking at your shell history to re-run the 2 same commands
• You tried to automate some tasks in your project with a Makefile, but it ended up having more lines inside than your entire projects
• You colleagues ALWAYS have an issue with their PATH environment variable.

# this copies my asset to the final directory
copy-assets:
cp -r assets dist
