Context RocksDB performs a variety of IO operations—user reads, background compactions, flushes, database opens, and verification tasks. Treating all these operations the same makes it difficult for file system implementers to optimize performance, prioritize latency-sensitive IOs, and diagnose bott...

​​Most software developers have heard the maxim, “it’s never a compiler bug,” and its companion, “it’s never a hardware bug.” But if you investigate enough bugs, you’ll eventually find an exception to this rule, and that’s what we found recently at HubSpot. I discovered how a hardware bug was affect...

Elephantshark helps you monitor, understand and troubleshoot Postgres network traffic: that’s Postgres servers, clients, drivers and ORMs talking to Postgres servers, proxies and poolers. Elephantshark sits between the two parties in a Postgres-protocol exchange, forwarding messages in both directio...

In a recent, real world problem I needed to load a heterogeneous sequence of records from a buffer. Record layout is defined in a header before the sequence. Each field is numeric, with a unique name composed of non-empty alphanumeric period-delimited segments, where segments signify nested structur...

AI is transforming how product managers and UX designers work, from vibe coding to automated workflows.

This post is intended to be the first in a series about empowering product, UX, and engineering teams with AI. We’re going to focus on how we’ve approached and scaled the use of AI in the context of writing code.

US politics has been pretty fascist lately. The state is filling up concentration camps, engaging in mass state violence against people on the basis of racialized traits, deporting them to random countries without any respect for habeas corpus, exerting state pressure on the free press to censor spe...

Context / Problem Modern RocksDB deployments often run in environments with strict memory constraints—cloud VMs, containers, or hosts with hundreds of DB instances. Unpredictable memory usage can lead to out-of-memory (OOM) errors, degraded performance, or even service outages. Historically, while t...

The Old Way vs. The Reality of Your Customers For years, the gold standard for benchmarking web performance, particularly for Google’s Core Web Vitals (CWV), has been a mobile device baseline—specifically, a throttled connection and CPU designed to simulate a Moto G4. This approach was established w...

This document details how preconnect improves web performance, especially for Bazaarvoice's third-party content, by accelerating connection setups and reducing LCP. Crucially, internal testing confirmed preconnect operations are not counted as API calls, validating a "no count, low cost" model—a key...

The DEBI (Data Engineering and Business Intelligence) team recently attended the DataEngBytes 2025 conference, where the hot topic for the year was, unsurprisingly, AI agents. My favorite talk, by Geoffrey Huntley, presented a powerful and surprisingly simple idea: It’s not that hard to build an age...

As I explained in my previous blog post on feature flags and testing, you need the flags to be the same to ensure consistent application behavior during end-to-end tests. If you want to test the specific feature, control the flag from the test. But sometimes the tests unexpectedly fail when one of t...
