Since WhatsApp introduced multi-device capability last year, we’ve seen an increase in people accessing WhatsApp directly through their web browser via WhatsApp Web. With this shift in mind, we’ve been looking at ways to add additional layers of security to the WhatsApp Web experience. Starting today, you can now use Code Verify, an open source… Continue reading Code Verify: An open source browser extension for verifying code authenticity on the web

Einstein Evaluation Store — Beyond Metrics for ML/AI Quality An important transition is underway in machine learning (ML) with companies gravitating from a research-driven approach towards a more engineering-led process for applying intelligence to their business problems. We see this in the growing field of ML operations, as well as in the shift in skillsets that teams need… Continue reading Einstein Evaluation Store — Beyond Metrics for ML/AI Quality

An important transition is underway in machine learning (ML) with companies gravitating from a research-driven approach towards a more engineering-led process for applying intelligence to their business problems. We see this in the growing field of ML operations, as well as in the shift in skillsets that teams need to successfully drive ML and artificial… Continue reading Einstein Evaluation Store — Beyond Metrics for ML / AI Quality

In a stereotypical heist, the thief’s “grab-and-go” plan often takes one of two forms. In the first, the thief grabs all they can and makes a loud and fast exit with explosives visible from miles away. In the second, the thief slowly and quietly amasses a fortune by stealing a few dollars at a time.… Continue reading Detecting Multithreaded Exfiltration in Zeek

What the research is: We’ve developed a new static analyzer that catches deadlocks in Java code for Android without ever running the code. What distinguishes our analyzer from past research is its ability to analyze revisions in codebases with hundreds of millions of lines of code. We have deployed our analyzer in Meta’s continuous integration… Continue reading An open source compositional deadlock detector for Android Java

We’ve improved read availability in LogDevice, Meta’s scalable distributed log storage system, by removing a fundamental trade-off in Flexible Paxos, the algorithm used to gain consensus among our distributed systems. At Meta’s scale, systems need to be reliable, even in the face of organic failures like power loss events, or when systems are undergoing hardware… Continue reading Augmenting Flexible Paxos in LogDevice to improve read availability
