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,…

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…

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…

Greykite: A flexible, intuitive, and fast forecasting library

Co-authors: Reza Hosseini, Albert Chen, Kaixu Yang, Sayan Patra, Rachit Arora, and Parvez Ahammad In this blog post, we introduce the Greykite library, an open source Python library developed to support LinkedIn’s forecasting needs. Its main forecasting algorithm, called Silverkite, is fast, accurate, and intuitive, making it suitable for interactive and automated forecasting at scale. We will start by describing a few applications, and then walk through the algorithm design and user experience. For more technical details, please refer to…

Accounting for sleep disorders in highway safety

Praveen Edara, chair of the Department of Civil and Environmental Engineering People with shift work sleep disorder (SWSD) are three times more likely to crash or be in a near-crash than people without that condition. That’s the take-away from a study on accident causes and sleep disorders conducted by civil and environmental engineering (CEE) professors Praveen Edara and Carlos Sun. In addition, they found that people with sleep apnea or insomnia had a 30% greater chance of crashing or nearly…

Video: Reverse osmosis: How engineers save lives

We all know that water quality is very important when it comes to public health. How have engineers helped to make clean drinking water possible in the United States, and what about the rest of the world? Professor David Schaad talks about the process of reverse osmosis and how it can help to save lives with clean water.

Humanity wastes about 500 years per day on CAPTCHAs. It’s time to end this madness

Select all the buses. Click on bikes. Does this photo have traffic lights? As ridiculous as these questions are, you’re almost guaranteed to have seen one recently. They are a way for online services to separate humans from bots, and they’re called CAPTCHAs. CAPTCHAs strengthen the security of online services. But while they do that, there’s a very real cost associated with them. Based on our data, it takes a user on average 32 seconds to complete a CAPTCHA challenge.…

Credit: PAN Dongfang Recently, a research group led by Prof. Cheng Lin from School of Microelectronics, University of Science and Technology of China (USTC) of the Chinese Academy of Sciences has made achievements in the field of fully integrated isolated power chip design. The researchers proposed a chip based on glass fan-out wafer-level package (FOWLP), achieving 46.5% peak transformation efficiency and 50mW/mm2 power density. Compared with the traditional isolated power supply chip,…
