Achieving observability in async workflows | by Netflix Technology Blog | May, 2021

Written by Colby Callahan, Megha Manohara, and Mike Azar. Managing and operating asynchronous workflows can be difficult without the proper tools and architecture that puts observability, debugging, and tracing at the forefront. Imagine getting paged outside normal work hours — users are having trouble with the application you’re responsible for, and you start diving into logs. However, they are scattered across multiple systems, and there isn’t an easy way to tie related messages together. Once you finally find useful identifiers,…

More sensitive than a dog’s nose, and the sensors don’t get tired — ScienceDaily

We are frequently reminded of how vulnerable our health and safety are to threats from nature or those who wish to harm us. New sensors developed by Professor Otto Gregory, of the College of Engineering at the University of Rhode Island, and chemical engineering doctoral student Peter Ricci, are so powerful that they can detect threats at the molecular level, whether it’s explosive materials, particles from a potentially deadly virus or illegal drugs entering the country. “This is potentially life-saving…

How Pinterest Fights Spam Using Machine Learning | by Pinterest Engineering | Pinterest Engineering Blog | May, 2021

Vishwakarma Singh | Trust and Safety Machine Learning Lead Hundreds of millions of people regularly visit Pinterest to visually discover inspiring ideas among billions of Pins. Inspiration is a high bar and we must be vigilant in ensuring that Pinners don’t see spam, harmful content or misinformation. To enforce our community policies and maintain an inspiring environment, we use the latest in machine learning technology to build automated systems that swiftly detect and act against both spammy content and spammers.…

Introducing Orbit, An Open Source Package for Time Series Inference and Forecasting

Orbit is a general interface for Bayesian time series modeling. The goal of Orbit development team is to create a tool that is easy to use, flexible, interitible, and high performing (fast computation). Under the hood, Orbit uses the probabilistic programming languages (PPL) including but not limited to Stan and Pyro for posterior approximation (i.e, MCMC sampling, SVI). Below is a quadrant chart to position a few time series related packages in our assessment in terms of flexibility and completeness.…

New sensors detect explosive materials, viral particles at part-per-quadrillion level

University of Rhode Island Professor Otto Gregory and URI doctoral student Peter Ricci demonstrate and explain how the sensors developed in the Thin Film Sensors Laboratory at URI can be used on drones to identify security and health threats at the molecular level. URI doctoral student Peter Ricci (left) and Professor Otto Gregory test the Digital Dog Nose sensors platform in Gregory’s Thin Film Sensors Laboratory at URI. The blue devices on the table represent the two latest versions of…

Automating Cloudflare Tunnel with Terraform

Cloudflare Tunnel allows you to connect applications securely and quickly to Cloudflare’s edge. With Cloudflare Tunnel, teams can expose anything to the world, from internal subnets to containers, in a secure and fast way. Thanks to recent developments with our Terraform provider and the advent of Named Tunnels it’s never been easier to spin up. Classic Tunnels to Named Tunnels Historically, the biggest limitation to using Cloudflare Tunnel at scale was that the process to create a tunnel was manual.…

Graduate Samantha Sample off to NYC to Work as Software Engineer

With two internships at Google, research experience and a Mizzou Engineering education behind her, 2021 graduate Samantha Sample is headed to New York City to work as a software engineer. Sample is receiving a bachelor’s in computer science and will be among the 300-plus undergraduate engineers participating in commencement ceremonies Saturday, May 15. Following graduation, she will start a job as a software engineer at Datadog, a monitoring and security platform company with offices around the globe. “I’m excited,” she…

Atanasov Heading to Bulgaria to Work in Cloud Computing

Adrian Atanasov graduates this weekend after five years of juggling school and a full-time job. It was grueling at times, he said, but he wouldn’t change a thing. “Working and going to school at the same time turned me into a different person than I would have been had I just gone to school,” he said. “And I’m very thankful for that. Initially, my goals were strict and clear cut. Now, I want to enjoy life and see where it…

Screening for ovarian cancer did not reduce early deaths — ScienceDaily

A large-scale randomised trial of annual screening for ovarian cancer, led by UCL researchers, did not succeed in reducing deaths from the disease, despite one of the screening methods tested detecting cancers earlier. Results from the UK Collaborative Trial of Ovarian Cancer Screening (UKCTOCS) have been published in a report in the medical journal The Lancet. In the UK, 4,000 women die from ovarian cancer each year. It is not usually diagnosed until it is at a late stage and…

Running BGP in large-scale data centers

What the research is: A first-of-its-kind study that details the scalable design, software implementation, and operations of Facebook’s data center routing design, based on Border Gateway Protocol (BGP). BGP was originally designed to interconnect autonomous internet service providers (ISPs) on the global internet. Highly scalable and widely acknowledged as an attractive choice for routing, BGP is the routing protocol that connects the entire internet. Similar to online map services for streets, BGP directs data packets, helping determine the most efficient…
