Programming Is Terrible: Lessons Learned From a Life Wasted (🔗 Read Paper)
Code isn't just written—it’s maintained and, eventually, deleted. The fewer lines of code in your system, the lower the maintenance cost, but aiming for reusable code can backfire by creating dependencies that make future changes difficult. A better approach? Treat code as a temporary solution, not a permanent fixture. The easier code is to delete, the better it serves its purpose.
Key Points
Avoid complex dependencies: Repeating yourself within reason can prevent unnecessary connections between different parts of the code. Use layers—simple, clumsy components underneath polished APIs—to separate what changes frequently from what remains stable.
Balance copy-pasting and abstraction: Copy-pasting code a few times is better than rushing into shared APIs. However, once the pattern solidifies, moving code to a function or utility can minimize future rewrites—just don’t let these utilities accumulate unchecked into one monolithic file.
Layer for adaptability: Instead of trying to reuse everything, write code that is easy to delete. Wrap third-party libraries to insulate your code from upstream changes, ensuring flexibility. Simple-to-use APIs help manage complexity without locking in every decision early.
Investigation of a Workbench UI Latency Issue (🔗 Read Paper)
At Netflix, the Analytics and Developer Experience organization recently uncovered a puzzling issue with Workbench, their remote development workspace. Users reported that JupyterLab UIs would become unresponsive when running certain notebooks, triggering an in-depth investigation involving everything from user code to container resources and the Linux kernel. Through trial, error, and network diagnostics, the Netflix Data Platform team embarked on a journey to identify the root cause.
Key Points
Initial symptoms: Some notebooks running on Workbench caused severe UI delays despite attempts to restart the ipykernel process.
Unexpected culprits: Oversubscription of CPUs and the use of Python’s pystan library were ruled out, leading the team to investigate the JupyterLab process itself.
Root cause found: Profiling revealed that a JupyterLab extension, jupyter_resource_usage, was overloading the system by recursively querying child processes, exacerbated when large files were read into memory.
Jujutsu: A New, Git-Compatible Version Control System (🔗 Read Paper)
Jujutsu, a distributed version control system initially created as a hobby project by Martin von Zweigbergk in 2019, offers a simplified, more performant alternative to Git. Unlike Git-based tools like Magit, Jujutsu aims for full independence from Git, though it currently interacts with Git repositories through the libgit2 library. Written in Rust and licensed under Apache 2.0, the system introduces a novel approach to merge conflicts by allowing conflicts to be stored and resolved in later commits — an idea borrowed from patch-based systems like Darcs.
Key Points
Performance and design innovations: Jujutsu speeds up operations like rebasing by avoiding unnecessary commit graph traversal and reimagining the working tree as a live commit, eliminating the need for staging with commands like Git add.
Feature limitations: The project currently lacks support for hooks, submodules, sparse checkouts, and Git LFS, though efforts are underway to incorporate partial hook support without disrupting the in-memory operation model.
Future prospects: With support from Google, Jujutsu aims to integrate a backend for cloud-based storage, but the tool’s future adoption hinges on whether its streamlined interface can offset the absence of Git's more advanced features.
Does Open Source AI Really Exist? (🔗 Read Paper)
The Open Source Initiative (OSI) has released RC1, the first “release candidate,” of its “Open Source AI definition.” This marks a near-final draft of what could become a foundational framework for AI systems to meet Open Source standards. OSI’s role isn’t just about code visibility; it also governs licensing to ensure software aligns with Open Source principles. The release raises questions whether the definition truly maintains the open ethos, particularly regarding data transparency. This initiative touches not only on technology but also the political consequences of defining what counts as Open Source in AI.
Key Points
The fine print of Open Source AI: OSI’s new definition outlines requirements beyond code, such as model parameters and architecture. However, it leaves wiggle room for “unshareable” training data, which critics argue undermines the principles of open source. The concern? Simply providing descriptions instead of data could render models opaque.
AI isn’t just code: AI systems rely heavily on training data, often more than the underlying code itself. Without full access to this data, the promise of reproducibility, transparency, and trust falls short—raising doubts about how Open Source standards can apply to large AI models.
Is open source AI an illusion?: Given the scale of modern AI models, many believe that fully Open Source AI is impossible. This definition could provide cover for companies to engage in “openwashing,” offering partial openness for proprietary systems. OSI’s approach, some say, may reflect the influence of corporate interests rather than staying true to Open Source ideals.
