Proteins are essential to life, supporting practically all its functions. They are large complex molecules, made up of chains of amino acids, and what a protein does largely depends on its unique 3D structure. Figuring out what shapes proteins fold into is known as the “protein-folding problem”, and has stood as a…
Developers can now integrate GPT‑3.5 Turbo and Whisper models into their apps and products through our API.
Signal’s mission and sole focus is private communication. For years, Signal has kept your messages private, your profile information (like your name and profile photo) private, your contacts private, and your groups private – among much else. Now we’re taking that one step further, by making your...

Perplexity is repeatedly modifying their user agent and changing IPs and ASNs to hide their crawling activity, in direct conflict with explicit no-crawl preferences expressed by websites.
We’re introducing Llama 4 Scout and Llama 4 Maverick, the first open-weight natively multimodal models with unprecedented context support and our first built using a mixture-of-experts (MoE) architecture.
Archived MIT Admissions blog post 'We are reinstating our SAT/ACT requirement for future admissions cycles,' published March 28, 2022. Preserved for historical context; not maintained as current admissions policy.
We are excited to introduce the Waymo World Model, a frontier generative model that sets a new bar for large-scale, hyper-realistic autonomous driving simulation.
This is a draft I wrote in early 2015 and never got around to publishing. Here’s the mostly unpolished version because it wasn’t doing anybody any good sitting in my drafts folder. The simplest change was updating year 2015 to 2016 at publication time.
Signal is the world’s most widely used truly private messaging app, and our cryptographic technologies provide extra layers of privacy beyond the Signal app itself. Since launching in 2013, the Signal Protocol—our end-to-end encryption technology—has become the de facto standard for private commu...
Ahmed Mansoor was targeted by NSO Group, an Israel-based “cyber war” company that sells Pegasus, a government-exclusive “lawful intercept” spyware product.
In biology class, biology wasn't presented as a quest for the secrets of life. The textbooks wrung out the questing.
One of the key gaps in Rust’s ecosystem has been a strong story for fast and productive asynchronous I/O . We have solid foundations, like the mio library, but they’re very low level: you have to wire up state machines and juggle callbacks directly.
Over my 17 years at Amazon, I have seen that my colleagues on the engineering team are never content to leave good-enough alone. They routinely re-evaluate every internal system to make sure that it is as scalable, efficient, performant, and secure as possible. When they find an avenue for improvement, they will use…

No single cloud fits all. Explore how we build a more flexible future with hybrid cloud.
I’ve observed thousands of founders and thought a lot about what it takes to make a huge amount of money or to create something important. Usually, people start off wanting the former and end up...
Update, March 13, 2018 Wildcard certificate support is live. Let’s Encrypt will begin issuing wildcard certificates in January of 2018. Wildcard certificates are a commonly requested feature and we understand that there are some use cases where they make HTTPS deployment easier. Our hope is that offering wildcards…
In the “first half of 2016” (the most specific we’re permitted to be), we received a subpoena from the Eastern District of Virginia. The subpoena required us to provide information about two Signal users for a federal grand jury investigation. We’ve designed the Signal service to minimize the dat...
Slack uses PHP for most of its server-side application logic, which is an unusual choice these days. Why did we choose to build a new project in this language? Should you? Most programmers who have only casually used PHP know two things about it: that it is a bad language, which they would never use if…
Behind the beautiful imagery of the latest animated movie and the realistic environments of popular videogames lie some mysterious algorithms. Computer Graphics from Scratch aims to demystify these algorithms and shows you that computer graphics can be surprisingly simple.
On April 18 at least six police officers from the National Operations Department (NOA) of the Swedish Police visited the Mullvad VPN office in Gothenburg with a search warrant. They intended to seize computers with customer data.
Many programming "best practices" taught today are performance disasters waiting to happen.
