Are there any existing Tailscale blog posts that describe some of the unique ways you all are using SQLite? Sounds like a fun read

Finally pulled the trigger on Math Academy.

I haven’t taken a math course since Calc 2 in 2017, which was so hard for me I changed majors.

My goal is to follow the foundations path through Discrete Mathematics.

Root causing a bug is one of the greatest feelings as a software engineer

Discussing quorum with 4 people seems risky

Great discussion today! A surprising amount of Ceph mentions and I had to bring up the napkin math repo a few times

Madison Systems is having another paper discussion this Saturday on The Google File System. Hope to see you there!

I contributed SHOW CLIENTS metrics to the Prometheus PgBouncer exporter. Similar to pg_stat_activity, but for PgBouncer. Now you can monitor client connections over time.

New blog post about the most important thing I've learned while ramping up on Node.js:

Don't block the event loop.

I noticed this SQLite query averaging ~90ms event though package_name is the PK, the table has ~865k rows and is ~166MB. Param is a prefix pattern like 'duck%'.

Any guesses why it was still that slow?

-23%

What a night to blow some snow

Madison Systems will be discussing a paper on "Gray Failure", subtle underlying faults rather than obvious fail-stop failures.

If you've seen this in production, reply! I'd love to bring real examples into the conversation.

Excited to announce I'm switching teams at Supabase. Going to be a SWE on the storage team. If you have any feedback on the product my DMs are open 🫡

It's IP based and probably bots but I don't discriminate I welcome all humans and bots to my site :)

That's my old surface book 3 that was just sitting in my closet. The specs are:
- i7-1065G7
- 16GB RAM
- 256GB
- NVIDIA GeForce GTX 1660 Ti

Plan is to have the mini PCs in a HA K3 setup but I know nothing about this stuff so figuring it out as a I go.

Only 256GB in each mini PC

You got to be kidding me, even directories are files!?

Homelabbing is a slippery slope...

Also, just found out @readwise.bsky.social has built in support for pdfs and it's really good

Weekend goal is to get secure, zero-touch device provisioning working in my homelab.

I used AI to contribute to an OS project, mise, and I would lying if I said I fully understood the code it generated. I decided to write about my experience. Open source is getting flooded with AI slop, I hope this shows a better way to contribute.

Reminds me of this quote:

This weekend's rabbit hole was so fun I had to write about it. I went from cheap mini PCs on eBay to learning how Chick-fil-A and Home Depot run Kubernetes inside their stores.

With great power comes great responsibility

> tailscale is the secure way to connect all your computers!

> i've used tailscale to connect my molty to all my computers and internal services and gave it all my keys

oh no, not like that

Using Quarto for my blog was one of the best decisions ever made. Just found out today it has native support for mermaid diagrams

Shelving just came in, the mini rack is complete!
