While traveling through airports, we usually don’t give a second thought about why our boarding passes are scanned at various places. After all, it’s all for the sake of passengers’ security. Or is it? The fact that boarding pass security is broken has been…

zxcvbn: Low-Budget Password Strength Estimation

Daniel Lowe Wheeler, Dropbox Inc.

For over 30 years, password requirements and feedback have largely remained a product of LUDS: counts of lower- and uppercase letters, digits and symbols. LUDS remains ubiquitous…

I spent the past 6 years creating a game engine, and I've been shocked at the things…

In December 2021, some ISPs in Russia started blocking Tor's website,
along with protocol-level (DPI) and network-level (IP address) blocking to
try to make it harder for people in Russia to reach the Tor network. Some
months later, we're now at a steady…

Formulas for the nth prime number actually exist! One was cleverly engineered in 1964 by C. P. Willans. But is it useful?

This talk will discuss recent changes to the Go memory manager, which improved both the runtime’s responsiveness in giving up unneeded memory and the scalability of the memory allocator. In this presentation, Michael peeks under the hood of the runtime, examines…

Modern hardware is highly parallel, but not only in terms of multiprocessing. There are many other forms of parallelism that, if used correctly, can greatly boost program efficiency — and without requiring more CPU cores. One such type of parallelism actively…

Fourteen years after the launch of Go, there is much to think about. With the benefit of hindsight, this talk explores some of the lessons learned from Go's progress so far: not just the things that went well but also the things that could have been done…

A supercut of all our weird light episodes. A look at the double-slit experiment, the Bell experiment, quantum eraser, the delayed choice experiment, the photoelectric effect, the three-polariser paradox, and more! Prepare for your world to be turned upside…

In this video I explain how computers represent and do arithmetic on numbers, and some of the problems there. Then we look at sets, groups, rings, and finite fields, and see how these tools can provide a more robust way to do arithmetic over integers. Finally…

The widely-used “encoding/json” package is over a decade old and has served the Go community well. Over time, we’ve learned much about what works but also identified several flaws and shortcomings. What does the future hold for “json”? What will it take to…

*UPDATE: This video is re-uploaded with a better audio here https://youtu.be/7_o-YRxf_cc*

Covers how a binary is executed, what segments are mapped to memory, the purpose/working of stack and heap memory, and how values of Rust's data types are laid out…

We explore the evolution of culling and visibility determination in video games, building on work started over 30 years ago, and evolving with every generation of hardware.
