Makefile Tutorial by Example
I built this guide because I could never quite wrap my head around Makefiles. They seemed awash with hidden rules and esoteric symbols, and asking simple questions didn’t yield simple answers. To solve this, I sat down for several weekends and read everything I could about Makefiles. I've condensed the most critical knowledge into this guide. Each topic has a brief description and a self contained

Becoming a Better Writer as a Software Engineer
Writing is an increasingly important skill for engineering leaders. Indeed, poor writing can hamper career progression, above a certain level. Tactics for more clear, more frequent and more confident writing. I’ve observed that my writing is not up to par with my peers. How can I improve my professional writing, as someone working in tech?I get this question from many people: senior engineers who

Diving Deep on S3 Consistency
Diving Deep on S3 ConsistencyApril 20, 2021 • 1938 words I recently posted about Amazon S3 and how it’s evolved over the last 15 years since we launched the service in 2006 as “storage for the internet.†We built S3 because we knew customers wanted to store backups, videos, and images for applications like e-commerce web sites. Our top design priorities at the time were security, elasticity, relia
Breaking GitHub Private Pages for $35k
I found and reported this vulnerability with @ginkoid. This was actually the first report that paid out for me on HackerOne. At $35,000, it’s also the highest bounty I’ve received so far from HackerOne (and I believe the highest GitHub has paid out to date). A lot of bugs seem to be a mix of both luck and intuition. In this blog post, I’ll illustrate my thought processes in approaching such a targ
Maximizing Developer Effectiveness
Technology is constantly becoming smarter and more powerful. I often observe that as these technologies are introduced an organization’s productivity instead of improving has reduced. This is because the technology has increased complexities and cognitive overhead to the developer, reducing their effectiveness. In this article, the first of a series, I introduce a framework for maximizing develope
How do you test your tests?
Facebook’s codebase changes each day as engineers develop new features and optimizations for our apps. If not validated, each of these changes could potentially regress the functionality or reliability of our products for billions of people around the world. To mitigate this risk, we maintain an enormous suite of automated regression tests to cover various products and apps. These tests are run at

How Google Cloud Storage offers strongly consistent object listing thanks to Spanner Here at Google Cloud, we're proud of the fact that, all of our listing operations are consistent across Google Cloud Storage. They're consistent across all Cloud Storage bucket locations, including regional and multi-regional buckets. They're consistent whether you're listing buckets in a project or listing object
Design Docs at Google
One of the key elements of Google's software engineering culture is the use of design docs for defining software designs. These are relatively informal documents that the primary author or authors of a software system or application create before they embark on the coding project. The design doc documents the high level implementation strategy and key design decisions with emphasis on the trade-of

I recently read an excellent article in the Amazon Builder’s Library by Clare Liguori which goes into great detail about AWS’s CI/CD architecture. It’s a truly brilliant post and I recommend everyone interested in CI/CD infrastructures read the article.
