E A nice chart of the most commonly used univariate distributions and their relationships
Published in the American Statistician (Leemis and McQueston, 2008). I've found this extremely helpful as a quick reference and often share with my students.

The paper itself has all the density functions and additional useful tidbits about how distributions are related.

How do you abbreviate cumulative in your feature names?
Not trolling but I want to know how do you all abbreviate cumulative x for a feature name. For example cumulative streamed minutes for past 7 days can be cum_streamed_min_L7. I feel uncomfortable putting that name in presentations.

D Trying to find paper about n-grams in early transformer layers
I remember reading a paper a while back that showed early attention layers in a transformer could be replaced with a simpler mechanism since most heads only modeled small n-grams. I think they used some kind of pooling?
Wondering if anyone knows which paper that was and had any thoughts about it since then. Thanks!

[P] XetHub: We scaled Git to support 1 TB repos
Thanks to everyone who replied to our [earlier post requesting pre-launch product feedback](https://www.reddit.com/r/mlops/comments/zd7hqy/feedback_requested_new_data_storage_tool_for/)! We’re excited to announce that we’ve now publicly launched [XetHub](https://xethub.com/?utm_source=reddit&utm_medium=organic&utm_campaign=xethub-intro&utm_content=link), a collaborative storage platform for data management.
I’ve been in the MLOps space for \~10 years, and data is still the hardest unsolved open problem. Code is versioned using Git, data is stored somewhere else, and context often lives in a 3rd location like Slack or GDocs.
This is why we built XetHub, a platform that enables teams to treat data like code, using Git.
Unlike Git LFS, XetHub doesn’t just store the files. It uses content-defined chunking and Merkle Trees to dedupe against everything in history, allowing small changes in large files to be stored compactly. Here’s how it works: [https://xethub.com/assets/docs/how-xet-deduplication-works](https://xethub.com/assets/docs/how-xet-deduplication-works)
XetHub includes a GitHub-like web interface that provides automatic CSV summaries and allows custom visualizations using Vega. And we know how painful downloading a huge repository can get, so we built Git-Xet mount—which, in seconds, provides a user-mode filesystem view over the repo.
Today, XetHub works for 1 TB repositories, and we plan to scale to 100 TB in the next year. Our implementation is in Rust (client & cache + storage) and our web application is written in Go.
XetHub is available today for Linux & Mac (Windows coming soon) and we’d love for you to try it out!

WLB suddenly turned toxic
Everything was nice, the WLB was good. Then the company got acquired by another larger fish and the WLB changed badly. I am currently working on a project where the manager expects us to work all day long. He himself works till 2-3AM. And I don't want to know why and how, but this will always be a mystery
He keeps saying this is critical and has a tight deadline.
I wish I could just say f### this criticality and tight deadlines. I can't be working 12-14 hours everyday and exhaust myself. I literally see blurr and severe headaches after the 10-11th hour.
This has been going on for 3 weeks continuously now and every time he keeps saying how we need to pace up and match his level of speed and commitment and he literally asks us to be "robots" and keep working.
I did hear of past employees changing teams because of his way of working.
PS : there is a time difference of 6 hours and he literally keeps on messaging us on MS Teams for updates, asks us for calls and updates at midnight!!!
