Frontend#

• Added support for changing cell languages
• Fixed bugs in the run queue which allows cells to become queued twice

Backend#

• Fixed issues with the authorizer policy that didn't properly cache per function
• Deployed a demo server to AWS
• Added support for changing a cell's language

Frontend#

• Created a Redux middleware to support the @actually-colab/editor socket client
• Moved the Kernel to a Redux middleware
• Auto select the example notebook for first time users, auto open the most recently opened notebook if possible
• Users can make edits to cells as changes are debounced in the @actually-colab/editor client
• Keep track of execution wall time and render it under a cell
• Automatically disconnect from the socket and kernel upon closing the window
• Released the v0.1.0 of @actually-colab/desktop-launcher

Backend#

• Created a client for the websocket endpoints
• Setup Google OAuth to allow clients to sign in
• Added an endpoint to refresh session tokens
• Added an event emitter to properly type events from the socket server
• Added support for opening notebooks and getting the contents
• Added support for locking and unlocking cells and notifying clients
• Added support for editing cell contents and notifying clients

Frontend#

• Separated the notion of a "selected" cell from a "locked" cell. This allows the run button to be able to advance without locks
• Added the ability to queue cell executions that way you can start a bunch of jobs and walk away
• Allowed the user to interrupt a cell execution. If a cell gets carried away or you accidentally start a long process, you can stop at any time
• Added the ability to disconnect from a kernel as well as disable auto connecting
• Users can now export their project to the ipynb format which could be used in jupyter, Google Colab, turned in as a deliverable, etc.
• Integrated the get/create notebook REST endpoints from @actually-colab/editor so users can create and see a list of notebooks
• Converted the cells and outputs to nested Immutable maps and lists to improve performance and avoid mutating the redux store

Frontend#

• Integrated @nteract's Open Source outputs component to replace my manual version. This added support for more output types at a slight trade off of speed and bundle size. The main benefit is a big boost to maintainability, don't need to reinvent the wheel for rendering complex outputs
• Implemented the kernel panel with logs of when various actions occurred
• Keep trying to connect to the kernel periodically in case the user doesn't start it till after
• Detect a kernel disconnect and connect to a new kernel if it dies
• Added support for LaTeX in markdown
• Added a help panel that explains how to setup the kernel as well as common issues for displaying output with things like matplotlib and pandas

Frontend#

• Started separating the electron application into a web hosted frontend and a smaller native kernel manager. This decreases our native platform dependency because our core client is available via a browser regardless of platform. This even allows it to be run on an iPad.
• Moved authentication directly into the client since redirects are no longer necessary with a web app
• Added support for markdown cells with syntax highlighting and rendering as html
• Added support for rich html outputs like pandas DataFrames
• Stripped down the newly forked desktop-launcher into a minimal kernel process manager
• Secured the Kernel Gateway by automatically setting the Access-Control-Allow-Origin header depending on if it is dev or prod

Backend#

• Created the client for all CRUD endpoints that can now be used by the frontend
• Refactor Notebook and User tables from DynamoDB to Postgres
• Reconfigured the environment to be ran and tested locally with ease
• Created Lambda authorizer functions and configured authentication for local development
• Enabled the socket connect/disconnect endpoints to track active user sessions
• Began architecting the websocket endpoints End-to-End

Misc#

• Adjusted the milestones/projects tabs to track open issues more cloesly

Frontend#

• Implemented the auth redirects with our website
• Added support for cell locking, creating new cells, deleting cells, and editing them locally
• Built output component to support text, base64 images (matplotlib outputs) and renders ANSI encoded errors with tracebacks
• Incorporated the kernel gateway into a hidden renderer that communicates via IPC and is automatically managed by the main process

Misc#

• Setup a Google Cloud project with OAuth client ID's
• Verified the GitHub organization

Backend#

An overview of the demo goals was put together here

• Fleshed out the development environment
• Configured DynamoDB resources in the Serverless config
• Added connect/disconnect entrypoints for the socket server
• Created a few CRUD endpoints for interacting with notebook configs

Frontend#

• Started a repo for the website
• Designed an auth scheme using Google OAuth that will be compatible with Electron https://github.com/actually-colab/desktop/issues/49
• Added wireframes for auth
• Various additions to side/menu bars of the app

Misc#

• Created this docs site and deployed with Netlify
• Acquired the domains actuallcolab.org and actuallycolab.com
