Possible disadvantages of ACE (Ajax Code Editor)

  • Performance Limitations
    Being a JavaScript-based editor running in the browser, ACE may experience performance issues when handling particularly large files compared to native desktop editors.
  • Lack of Advanced IDE Features
    ACE is mainly a code editor and does not provide some of the advanced features found in full-fledged IDEs, such as built-in debugging tools or integrated terminal support.
  • Limited Offline Use
    Since ACE is designed for web-based environments, there might be limitations or additional steps required to use it effectively offline.
  • Dependency on Browser
    The performance and capability of ACE can vary depending on the browser being used, making it subject to each browser's limitations and quirks.
  • Learning Curve
    Setting up custom configurations and understanding the full range of features may require a learning period, especially for users new to web-based editors.

Analysis of marimo

Overall verdict

  • marimo is an excellent modern reactive notebook for Python that solves many of the pain points associated with traditional notebooks like Jupyter, making it a strong choice for reproducible, interactive, and shareable data work.

Why this product is good

  • Reactive execution model automatically re-runs dependent cells when a variable changes, eliminating hidden state and out-of-order execution bugs common in Jupyter
  • Notebooks are stored as pure Python (.py) files, making them git-friendly, easy to diff, and importable as modules or executable as scripts
  • Built-in interactive UI elements (sliders, dropdowns, tables) that bind directly to Python variables without callbacks or extra frameworks
  • Can be deployed as interactive web apps or dashboards directly from the notebook, blurring the line between exploration and production
  • Open source with active development and a growing community, plus fast performance and a clean, modern interface

Recommended for

  • Data scientists and analysts who want reproducible, bug-free notebook workflows
  • Developers who value version control and want notebooks that work well with git
  • Educators and teams building interactive dashboards or demos from Python code
  • Anyone frustrated with Jupyter's hidden state and out-of-order execution issues
  • Researchers who need to share reproducible, executable analyses

  • Show HN: Write Code to Solve Minigames
    Hi HN! Codyssey is a small programming game where you write Python functions to solve minigames. Think pong, flappy bird - the functions serve as a control mechanism for the player. It evolved from an end-of-year activity I made for an introduction to programming class for 9th graders, difficulty has been adjusted obviously. I ran it as a workshop / competition at several conferences, now considering making it... - Source: Hacker News / 12 months ago

  • Show HN: A note-keeping system on top of Fossil SCM
    I used a note system built on top of Fossil as my primary system for quite a while. Here are the details in case anyone is interested. Fossil allows CGI extensions[1]. There's a database for tickets, but that's just a regular SQLite table that you can use to store anything you want, and it's version controlled and queryable. I stored the notes plus metadata in the tickets database. The CGI returned HTML with the... - Source: Hacker News / almost 3 years ago
  • Writing a (simple) code editor for the web?
    Hey there! Thanks for reaching out. Writing a code editor with syntax highlighting in a browser can be a little tricky, but it's definitely doable. One resource that might be helpful is the Ace Editor library (https://ace.c9.io/). It's a lightweight but powerful editor that includes syntax highlighting for a huge range of languages. You could also check out CodeMirror (https://codemirror.net/), which is another... Source: over 3 years ago
  • The ShnooTalk programming language
    The frontend uses the ace editor for syntax highlighting and then sends all the "text" you have typed to a python backend. The backend then writes all the text to a temporary directory and calls the compiler using subprocess (something similar to os.system). Source: almost 4 years ago

  • Pluto.jl 1.0 release โ€“ reactive notebook for Julia
    Pluto is great. I use it all the time. If you like the reactivity/reproducibility but are wedded to Python, you might want to check out Marimo, which is also great. [https://marimo.io/] It too puts the output of a cell above the code so if you're unable to adapt to things that are different it's also probably not for you. FWIW, Observable's Notebooks (Javascript) work the same way: output above the code... - Source: Hacker News / 2 months ago

  • Why DuckDB is my first choice for data processing
    Agree with the author, will add: duckdb is an extremely compelling choice if youโ€™re a developer and want to embed analytics in your app (which can also run in a web browser with wasm!) Think this opens up a lot of interesting possibilities like more powerful analytics notebooks like marimo (https://marimo.io/) โ€ฆ and thatโ€™s just one example of many. - Source: Hacker News / 7 months ago

  • Installing & Working with Python - in Ubuntu 24.04
    Marimo is a Jupyter notebook with each cell being somewhat logically connected to each other. That's way if you update the value of a variable in a cell and re-run it, related values in other cells will be auto-updated and auto-run. This is called reactive execution. Thus the notebook can act as a single python script or app and has an extension of .py instead of .ipynb. - Source: dev.to / 9 months ago
