In 2018, Dropbox has focused on improving our world-class bug bounty program. From increasing bounties to protecting our researchers, we’re always looking for more creative and meaningful ways to stay ahead of the game when it comes to running this program.
As an example, we recently partnered with HackerOne to host their H1-3120 live-hacking event in Amsterdam. Live-hacking events let participants hack on a target—often in person—submit vulnerabilities, and receive bounties quickly, all during the course of the event. Live-hacking comes with a number of benefits over traditional bug bounty programs, such as real-time communication and relationship building,
Modernizing the front-end stack
The core Dropbox web application is 10 years old and used by millions of users per day. Hundreds of front-end engineers across multiple cities actively work on it. Unsurprisingly, our codebase is very large and somewhat irregular. Recently written parts have thorough test coverage, other parts haven’t been updated in years.
Over the past two years we’ve worked to modernize our front-end stack. We’ve successfully moved from CoffeeScript to TypeScript, from jQuery to React, and from a custom Flux implementation to Redux. Having completed these migrations we identified our utility library, Underscore, as one more candidate for migration.
Last month at Dropbox Open London, we unveiled a new technology preview: Project Infinite. Project Infinite is designed to enable you to access all of the content in your Dropbox—no matter how small the hard disk on your machine or how much stuff you have in your Dropbox. Today, we’d like to tell you more—from a technical perspective—about what this evolution means for the Dropbox desktop client.
Traditionally, Dropbox operated entirely in user space as a program just like any other on your machine. With Dropbox Infinite, we’re going deeper: into the kernel—the core of the operating system.
Project Schedule Estimation in Software Development
In tech, we spend little time talking about the softer skills like communication, project management, and prioritization. These are the skills that elevate someone from a good programmer to a great software engineer. Today, I’m going to focus on one aspect of project management that we’re famously bad at — the art of estimating a project schedule.
If there’s any doubt that this is a necessary skill, just consider that dreaded but frequently-asked question “How long will it take?” Even if you’re uber-Agile and don’t believe in far-off project deadlines,
Today we’re excited to welcome a new member of the Dropbox family under unusual circumstances. Though he’s joining us now, his contributions to Dropbox date back to day one, all the way to the very first lines of code.
Some people only need to be introduced by their first name, and the BDFL is one of them. Dropbox is thrilled to welcome Guido, the creator of the Python programming language and a long-time friend of ours.
From the beginning,
It’s almost time for another Hack Week at Dropbox, and with that in mind I’d like to present one of the projects from our last Hack Week.
A profiler is an indispensable tool for optimizing programs. Without a profiler, it’s hard to tell which parts of the code are consuming enough time to be worth looking at. Python comes with a profiler called cProfile, but enabling it slows things down so much that it’s usually only used in development or simulated scenarios, which may differ from real-world usage.
At our last hack week, I set out to build a profiler that would be usable on live servers without impacting our users.
