The Washington State Derailment and Positive Train Control

After more than a decade of planning and construction, a new section of track was opened for Amtrak passenger service south of Tacoma, Washington on Dec. 18, 2017.  The old route that Amtrak trains used to take went northwest from Tacoma along the coast of Puget Sound, around a peninsula named Point Defiance, and then down the coastline several miles until it crossed Interstate 5 south of the small town of DuPont and headed south inland.  The new shorter route…

India’s new ‘driverless’ metro train keeps driver for now

India’s capital launched a metro train with driverless technology Monday, though officials said it would operate with a driver for at least a year or two. Prime Minister Narendra Modi took an inaugural ride on a short section of the 12.6-kilometer (7.8-mile) Magenta Line, which connects the southern part of New Delhi with the satellite city of Noida, an IT hub across the Yamuna river. The Delhi Metro Rail Corp. has said the highly automated train will run initially…

Maine robotics company competing for major Army contract

A Maine robotics company is one of four companies competing to build the Army’s next generation of battlefield support vehicles. The Army wants unmanned vehicles to reduce the burden on soldiers by carrying heavy ammunition and supplies into combat. The Portland Press Herald reports that the Army is expected to order thousands of the units by 2020. Waterboro-based Howe and Howe Technologies said its unmanned, tracked vehicle completed a 60-mile field test in 29 hours in September and October.…

TLS 1.3 is going to save us all, and why IoT is still insecure

As I’m writing this, four DDoS attacks are ongoing and being automatically mitigated by Gatebot. Cloudflare’s job is to get attacked. Our network gets attacked constantly. Around the fall of 2016, we started seeing DDoS attacks that looked a little different than usual. One attack we saw around that time had traffic coming from 52,467 unique IP addresses. The clients weren’t servers or desktop computers; when we tried to connect to the clients over port 80, we got the login…

New study visualizes motion of water molecules, promises new wave of electronic devices — ScienceDaily

A novel approach to studying the viscosity of water has revealed new insights about the behavior of water molecules and may open pathways for liquid-based electronics. A team of researchers led by the Department of Energy’s Oak Ridge National Laboratory used a high-resolution inelastic X-ray scattering technique to measure the strong bond involving a hydrogen atom sandwiched between two oxygen atoms. This hydrogen bond is a quantum-mechanical phenomenon responsible for various properties of water, including viscosity, which determines a liquid’s…

Preterm infants have narrowed upper airways, which may explain higher obstructive sleep apnea risk — ScienceDaily

Infants born preterm have significantly lower nasopharyngeal and oropharyngeal volumes, compared with newborn peers carried to full term, and those lower airway volumes are independent of the infants’ gender, ethnicity or weight, according to a study published online Dec. 16, 2017 in Clinical Imaging. According to the Centers for Disease Control and Prevention, 1 in 10 babies born in the United States is preterm, or born prior to the 37th gestational week. Premature birth leaves these children more susceptible to…

Animations of Motor Proteins Moving Material Inside Cells » Curious Cat Science and Engineering Blog

Animations of Motor Proteins Moving Material Inside Cells Posted on December 23, 2017  Comments (0) Very cool. This next video gives a bit more information on how these amazing parts of our cells move material around inside or cells. This stuff is so interesting. I wish this type of interesting material and informative animations was what my biology education was like in k-12 instead of the boring stuff my classes were instead. I hope students today have better science classes…

2017 Highlights from Uber Open Source

Since the beginning, Uber has relied on open source technologies to build reliable, production-hardened systems that can grow at scale. In this spirit, Uber Engineering has given back several technologies to the open source community, ranging from a data visualization framework and an iOS contacts library, to a signature rendering tool and even a new programming language.   As we ring in the New Year, let us revisit some of our most popular open source projects from 2017:    …

Technical reading from the Cloudflare blog for the holidays

During 2017 Cloudflare published 172 blog posts (including this one). If you need a distraction from the holiday festivities at this time of year here are some highlights from the year. CC BY 2.0 image by perzon seo The WireX Botnet: How Industry Collaboration Disrupted a DDoS Attack We worked closely with companies across the industry to track and take down the Android WireX Botnet. This blog post goes into detail about how that botnet operated, how it was distributed…
