The usefulness of an open source project is not an indication of the project's health, stability, or reliability in production!!!! AHHHHHHHHHHHHHHHHH

Kubernetes 1.34: Deep dive into new alpha features Prepare for the upcoming Kubernetes release by learning about the 13 alpha features it brings. They cover various areas of the project, from asynchronous API calls to the new KYAML format.

Hot take: With the US withdrawal from WHO, cutting off 20% of their source of funds… there are places like Kakuma refugee camp that will fall to their knees. The healthcare system there is heavily reliant on NGOs and this is going to be very very tricky moving forward.

Kubernetes – Don’t Use Certificates for Authentication .

When you deploy Kubernetes, you usually begin your access with a certificate. It's easy, it's simple, it doesn't require a login, and it's a TERRIBLE IDEA!!!!! Friends don't let friends use certificates for accessing Kubernetes. For TBT, our blog post explains why!

1. Impact. How much revenue does my work protect or generate?

2. Quality. Does my work meet or exceed customer expectations?

3. Efficiency. Reward making the right buy versus build decision.

4. Reusability. How do others leverage my work?

5. Supportability. How much work do I create for others?

I've got only one resolution. Stay focused.

The following benefits greatly outweigh that one drawback:
- markdown-based format making it easy to move these notes to my future blog
- lightweight and snappy
- customization with plugins
- notion lacks enough depth to be regarded as a ’second brain’ 🧠

Great question Casen, and I appreciate your curiosity!

So far there’s only one feature I would have loved to have in Obsidian, which technically already exists, just behind a paywall. That’s the ability to sync my notes between my devices.

Other than that, I don’t miss notion at all.

Officially migrated all my notes from Notion to Obsidian 💎

Just finished installing the Excalidraw addon and now I have my system architecture diagrams right where I want them, beside my notes.

Migration was simple and direct. Obsidian’s minimalism and simplicity was just too hard to resist. 🚀

This is genius!!

This gives me a top-level overview of what I’m about to read. Like reading source material before attending a lecture in uni. It’s a hack. Listening to it as I do the dishes, on a walk, on my commute. Very worth it. I’m definitely going to commit to the plus version of this.

Google you are exactly who you think you are. 🫵

Whenever I want to read a whitepaper of any sort, I first upload it as a source onto NotebookLM and create a podcast episode real quick. Without even mentioning the 'upload a YouTube video' feature, I’ve already 10X my learning.

Hi, so I've spent the past almost-decade studying research uses of public social media data, like e.g. ML researchers using content from Twitter, Reddit, and Mastodon.

Anyway, buckle up this is about to be a VERY long thread with lots of thoughts and links to papers. 🧵
