Tyler Hillery

On, Wisconsin!

Madison Systems has our next talk scheduled and the topic is "The Evolution of Deterministic Simulation Testing" Sign up here: luma.com/nka6507v?tk=...

I will be at Supabase Select! If you plan on going and want to meet up, let me know! select.supabase.com

Lots of talk on using AI for writing so here is a 100% human written blog post on how I started writing more without using AI for help. tylerhillery.com/blog/writing...

Wrote about some thoughts I've had around SQL as a query language. tylerhillery.com/blog/i-love-...

Supabase is now deploying >1m new Postgres databases every week & that doesn't include read replicas

Just found out you can use bat for man pages, very nice

Couldn't help but think of @jeffgeerling.com's video after reading this. youtu.be/v0DEI4Ad7Ik?...

Love this quote

Another great Madison Systems paper discussion! Which one should we read next?

New laptop day!

The next Madison Systems paper discussion is scheduled. This time at the Memorial Union Terrace to enjoy the WI summer. Register Here: luma.com/xdmbcw2t?tk=...

This is the paper that inspired me to get into systems programming www.usenix.org/system/files...

Another great Madison Systems paper discussion!

3 more days, get to reading!

High signal to me is seeing a company landing page that doesn't have "AI" in it. I think @turbopuffer.bsky.social is a great example of this. You'd think a vector DB would be all over "AI" but nope. Just their core value backed up by metrics.

This Tuesday, Hannes announced Quack, our new protocol that turns DuckDB into a client-server database. Watch his talk, recorded at the AI Council, where he explained how Quack works in practice, what stack it's built on, how it performs, and what our long-term ambitions are. youtu.be/L_lttD-d1wc

Reminder, Madison Systems is having another paper discussion in 2 weeks. This time, we'll be discussing: Scalability! But at what COST? luma.com/1enx2p3m

Huh, this is cool. I’d never really thought through why there’s a gap between the upper and lower case ranges in ASCII. tylerhillery.com/blog/why-don...

I wrote about a particular part of ASCII that finally clicked for me today tylerhillery.com/blog/why-don...

Perfect way to spend a Sunday

What bogus, I always thought these numbers were tied to physical measurements

Man I should have switched pypacktrends over to slot based pricing a while ago. Seems like once you get over the > 1TB scanned per month, bytes processed based billing isn't worth it

I wrote about why I like computers: tylerhillery.com/blog/link-bl...

You know it's serious when you bust out the debugger and start drawing diagrams

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

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! luma.com/zfh0lcxf

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. Wrote a bit about it: tylerhillery.com/blog/monitor...

New blog post about the most important thing I've learned while ramping up on Node.js: Don't block the event loop. tylerhillery.com/blog/tyler-t...

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 🫡

You got to be kidding me, even directories are files!? internals-for-interns.com/posts/filesy...

Up ~10k unique visitors on my personal site compared to last year

Homelabbing is a slippery slope...

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. tylerhillery.com/blog/using-a...

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. tylerhillery.com/blog/running...

> 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!
