Balancing open source and proprietary IP—they can co-exist

Open source software can provide significant benefits to an organization—it can decrease product development time, distribute development across a community, and attract developers to your organization. It’s because of these benefits that we at Dropbox love open source. However, some organizations shy away from it due to perceived risks and fears around lost intellectual property (IP) rights. You’re not alone if you’re worried that once you’ve incorporated open source into your products or open sourced your own code that you’ve…

The Curious Case of Caching CSRF Tokens

It is now commonly accepted as fact that web performance is critical for business. Slower sites can affect conversion rates on e-commerce stores, they can affect your sign-up rate on your SaaS service and lower the readership of your content. In the run-up to Thanksgiving and Black Friday, e-commerce sites turned to services like Cloudflare to help optimise their performance and withstand the traffic spikes of the shopping season. In preparation, an e-commerce customer joined Cloudflare on the 9th November,…

Why Some Phishing Emails Are Mysteriously Disappearing

Phishing is the absolute worst. Unfortunately, sometimes phishing campaigns use Cloudflare for the very convenient, free DNS. To be clear –– there’s a difference between a compromised server being leveraged to send phishing emails and an intentionally malicious website dedicated to this type of activity. The latter clearly violates our terms of service. In the past, our Trust and Safety team would kick these intentional phishers off the platform, but now we have a new trick up our sleeve and…

How soundscapes and vibrations are helping blind people see the world

Voice-Controlled Device Automates Window Blinds

Many homeowners have struggled with, and given up on, conventional blinds for one simple reason: the outdated and cumbersome pull cord. A key component in the proper functioning of the window blind, the pull cord can become unwieldy, often getting tangled or simply becoming a jumbled eyesore in an otherwise finely appointed room. For those that can afford to do so, replacing conventional blinds with a high-end motorized and automated alternative can more than adequately address these issues. For those…

Screaming Circuits: Communicating Up and Sideways

A good leader should communicate in the language of his or her subordinates. A good leader should be the one to adjust dialect and language. This is well accepted wisdom. The problem is that “should” is a rather meaningless word. “Should” doesn’t require, nor does it instruct. “Should” implies obligation, but doesn’t imply action or consequence of not taking action. Expecting a superior or colleague to speak in your language only ensures that you “should” be able to communicate, not…
