7d7n··on Improving recommendation systems and search in the age of LLMs
Not at all! I appreciate the kind words. Thank you!
7d7n··on Improving recommendation systems and search in the age of LLMs
haha that wasn't me ;)

Thank you for the feedback! I'm sorry you found it jargony/less accessible than you'd like.

The intended audience was my team and fellow practitioners; assuming some understanding of the jargon allowed me to skip the basics and write more concisely.

7d7n··on Bluesky Social Dataset (235M posts from 4M users)
Pollution of online social spaces caused by rampaging d/misinformation is a growing societal concern. However, recent decisions to reduce access to social media APIs are causing a shortage of publicly available, recent, social media data, thus hindering the advancement of computational social science as a whole. To address this pressing issue, we present a large, high-coverage dataset of social interactions and user-generated content from Bluesky Social.

The dataset contains the complete post history of over 4M users (81% of all registered accounts), totaling 235M posts. We also make available social data covering follow, comment, repost, and quote interactions.

Since Bluesky allows users to create and bookmark feed generators (i.e., content recommendation algorithms), we also release the full output of several popular algorithms available on the platform, along with their timestamped “like” interactions and time of bookmarking.

This dataset allows unprecedented analysis of online behavior and human-machine engagement patterns. Notably, it provides ground-truth data for studying the effects of content exposure and self-selection, and performing content virality and diffusion analysis.

haha I'm glad you noticed!

it's originally "Ready to ~~delve~~ dive in?" but something got lost in translation

100% agree with Ted's take. One of the authors wrote about splitting up prompts here too: https://eugeneyan.com/writing/prompting/#split-catch-all-pro...
7d7n··on Simplicity is an advantage but sadly complexity sells better (2022)
The goal is to solve complex problems with as simple a solution as possible.
7d7n··on Patterns for building LLM-based systems and products
For some use cases, legal reasons such as proprietary/private data, copyright, terms of service, prevent the use of a 3rd-party API.

On the other hand, directly using an off-the-shelf model, even the best ones, may not meet your performance requirements.

That’s where fine-tuning an open LLM is necessary.

7d7n··on Is Writing Documents as Important as Writing Code?
I've noticed that senior devs tend to spend more time writing documents (e.g., design docs, API specs) than coding.

How do you measure the impact of writing a document (vs coding a feature)? What's the right balance between both?

It doesn't seem to be solely health-related though. It seems specifically targetted at work-visa holders.

Wow, thank you for dissecting the post and and sharing your personal experience and lessons as well. Those are great learning points!

Yes I left soon after it was acquired by Alibaba (didn't like the 996) and wanted to put my skills to help in healthcare (in a 10-man startup).

On the first point: I assume you're asking for avenues to practice and demo your work. If so, personal projects are a great way.

The most impressive candidates can demo something they've deployed. This demonstrates the ability to apply what you've learned AND learn the rest of the stuff as needed (e.g., spin up EC2, build basic front end, maintenance, etc.). The latter is more important and gives confidence that you take ownership and likely can do the same (i.e., end-to-end with results) in the company.

On the second point: having meaning in work differs from person to person. Some people enjoy pushing the envelope (research), others enjoy staying hands-on (individual contributor, IC), while some big picture thinkers enjoy coordinating (PMs). It's helpful to think back on what gave you the greatest satisfaction and work with your leaders to be a role that lets you perform your best.

I find it most fulfilling to build data products that are useful, relative to generating tons of revenue. I would be equally happy as an IC doing the hands-on or leading a small team and mentoring them to become more effective.

I didn't recall any books helping much on communication.

With regard to presentation and speaking, I had great leaders around me who provided candid feedback the presentation was off-point, too long, or had to be re-ordered (e.g., when presenting to non-tech folks, results before methodology). It was also useful to "rehearse" any conference presentations at meet-ups and get feedback.

Feedback to improve written communication is harder to come by. Few people feedback on your design documents or reports. For this, I find blogging and seeking feedback from writers whose writing I enjoy to help the most.

Author here: I believe the missing step is being able to APPLY the knowledge and skills (learned from online courses) to create value.

It's not difficult, you just need to know that creating an artifact is not the end of your job--it needs to be used to benefit customers and generate value. Remember to measure the impact after your feature/system is launched.

I've seen many interview candidates struggle with this (missing step) too. Those that get past it were hungry enough to want it, as well as followed up with proper validation and measurement.
