Credit: Irene Georgakoudi, Tufts University Metabolic changes in cells can occur at the earliest stages of disease. In most cases, knowledge of those signals is limited, since we usually detect disease only after it has done significant damage. Now, a team led by engineers at Tufts University School of Engineering has opened a window into the cell…

How We’re Using Codable Protocol in Swift 4

At Wayfair, we’re keen to research, innovate, and invest in new technologies whenever the  opportunity arises. There are obvious advantages to this approach for our iOS teams in particular: It allows us to keep up to date with current developments and be prepared for potential API updates. This is particularly important for the Apple ecosystem, where technology changes every year bringing about newer and more reliable APIs for developers and users alike. We recently started exploring one such technology on…

European clocks slowed by lag in continent’s power grid

In this Nov. 1, 2017 file photo high power cables hang from a pole on a field in Hattersheim, Germany. ​​Millions of Europeans who arrived late to work or school Wednesday March 7, 2018 have a good excuse: an unprecedented slowing of the frequency of the continent’s electricity grid. The Brussels-based European Network of Transmission System Operators for Electricity, or ENTSO-E, says the problem began mid-January and affects 25 countries, from Portugal to Poland and Greece and Germany.

Flying cars eye takeoff at Geneva Motor Show

Pop.Up Next, a self-driving car and passenger drone by Audi, Italdesign and Airbus on display at the Geneva International Motor Show After gracing our screens for decades, flying cars are about to shift gears from dream to reality, with the unveiling of a commercial model in Geneva this week. From James Bond to The Jetsons, flying cars have long captured our imaginations, but now a Dutch company says they are almost ready to take to the streets, and the skies.…

Mizzou 3D Printing Club helps pup put best foot forward

The 3D Printing Club at Mizzou has developed a number of different models, each of which has been tested by Tucker. Photo by Brandon Mullen. Tucker is ready to put his best foot forward. With the help of the College of Engineering’s 3D Printing Club, Kendra Earl Warlow’s 5-year-old Australian Shepherd will soon walk on four paws. Born without his hind right foot, Tucker has adapted throughout his life to travel on just three. However, with age, he’s begun to…

Double disinfection treatment for safer drinking water

Credit: University of Eastern Finland In spite of good progress in water hygiene during the recent decades, contaminated water still causes millions of diseases every year. Most of these diseases are caused by enteric viruses, and better water disinfection methods could help prevent discomfort and even save lives. A new study from the University of Eastern Finland shows that a combined disinfection treatment with chlorine and UV radiation can be highly effective in…

Improved X-ray computed tomography for quality control of advanced manufactured parts

Credit: INTERAQCT A consequence of advanced manufacturing technologies is that some internal structures tend to be inaccessible and so quality control is necessarily destructive. This is clearly problematic for high-added value products, where customers nonetheless expect reliability and certified quality. Computed tomography (CT) has been heralded as an answer, making visible as it does internal structures and moreover combining dimensional metrology and material defect analysis. However, the technology has its limitations. The EU-funded INTERAQCT project created a research environment, harnessing…

Reykjavík, Cloudflare’s northernmost location

Iceland is a small country in Northern Europe, a land of active volcanoes and boiling hot geysers. The geology and climate creates unique conditions for running compute power. With an abundance of green electricity and natural cooling, many companies are placing high power machines in Iceland to run power intensive, heat generating operations. Reykjavík is our 125th location globally. Connecting to the rest of the world A unique aspect about Iceland relates to how it connects to the Internet, being…

HTTP Analytics for 6M requests per second using ClickHouse

One of our large scale data infrastructure challenges here at Cloudflare is around providing HTTP traffic analytics to our customers. HTTP Analytics is available to all our customers via two options: Analytics tab in Cloudflare dashboard Zone Analytics API with 2 endpoints In this blog post I’m going to talk about the exciting evolution of the Cloudflare analytics pipeline over the last year. I’ll start with a description of the old pipeline and the challenges that we experienced with it.…
