We talk a lot about how important it is to set up self-verification loops. Especially in the age of powerful models that can run for long periods of time, self-verification is a key ingredient that enables the model to run for much longer, delivering a result that is closer to what you intended, so you can do more without having to constantly check in on Claude as it works.

@delba_oliveira gives a great breakdown of what that looks like and why it matters

great advice from @simonw on how to store timestamps in a database

GTA Vice City may be over 22 years old, it's still a classic filled with secrets you might have missed. As we get ready to return to VC in GTA 6, it’s the perfect time to revisit these secrets.

These are Vice City's best and most terrifying secrets & easter eggs. A Thread🧵

I am pragmatic. The opposite of pragmatism is being driven by ideology. Ideology is helpful when creating something new, but it tends to fail in the long run. This applies to both software design and real life. Let me show some examples. /1

My shoddy ASCII art about writing data to disk was surprisingly popular, so I finished off an old set of notes talking more comprehensively about durably writing data to disk and added a better version of the diagram.

We had 6 engineers talking for 4 hours about a 2 line code change for an obscure edge case that will never happen.

Are all Fortune 500 companies like this?

Published a new blog post on explaining the basics of disaggregated storage systems.

The architecture is relatively new considering the rich history of databases, but pivotal enough to be adopted by many databases like Amazon Aurora, Neon, Snowflake, etc.

Very well-explained playlist on Computer Architecture.

This is one of the best (series of) visualizations for a replication protocol. Impressed to see this on the confluent site.

This is true - Rust is being productively used all across the industry. For example, it's the default choice for building new systems code at AWS, and is already running critical data planes (like S3, Lambda, and many others).

If you want to grow as a dev, hone your bullshit detector. If you hear a technical argument that sounds wishy-washy, don't accept it. Go figure out what the real deal is. You don't need to be rude about it. Just do it for yourself. Repeat for 10yrs and you'll be in a good spot.

Why are folks obsessed with tail latency? Isn't 9Xth percentile all that matters?

Basically: service-oriented architectures/microservices plus cloud services (which are both useful!) mean that even small fluctuations in latency can be greatly amplified.
