This ambulance cart could transform health care access in Tanzania

An illustration of the Okoa Project’s ambulance, which attaches to motorcycles in hard-to-reach rural areas. Credit: MIT Sloan School of Management In Tanzania, rural villages are often hours from medical facilities. Mortality among pregnant women is a grave problem: Lack of health care access results in complications and even death for either mother or baby. As many as 400 women die for every 100,000 live births. The Okoa Project aims to change this with motorcycle ambulances. Ambulances attach to bikes…

Growing organs a few ink drops at a time

Credit: Osaka University Printed replacement human body parts might seem like science fiction, but this technology is rapidly becoming a reality with the potential to greatly contribute to regenerative medicine. Before any real applications, “bioprinting” still faces many technical challenges. Processing the bio-ink and making it stick to itself and hold the desired printed gel structure have been proving particularly difficult especially in inkjet printing. Few methods currently exist…

Customer Satisfaction Measurement : Why and How ?

For an organization, customers are an excellent source of information as they can help us identify how a product or service is being perceived. The only caveat being, how to analyze this customer-centric data and bring it to competitive advantage. The process of measuring the customer satisfaction metric need not be expensive or complicated but an addition of a simple step to company’s existing customer strategy. ‘Overall Satisfaction Surveys’ are an effective way to understand how a product is being…

Why TLS 1.3 isn’t in browsers yet

Upgrading a security protocol in an ecosystem as complex as the Internet is difficult. You need to update clients and servers and make sure everything in between continues to work correctly. The Internet is in the middle of such an upgrade right now. Transport Layer Security (TLS), the protocol that keeps web browsing confidential (and many people persist in calling SSL), is getting its first major overhaul with the introduction of TLS 1.3. Last year, Cloudflare was the first major…

Bay Area aerial imaging startup teams up to detect disease in crops before outbreaks

An Oakland-based startup is sending its aerial imaging technology to the Midwestern plains to help farmers detect pests and diseases in their corn and soybean fields before an outbreak. Ceres Imaging announced this week that the startup, which raised $5 million for its Series A fund back in May, will partner with an agricultural cooperative serving in five counties in central Illinois. The partnership is a test, which Ceres Imaging’s founder Ashwin Madgavkar hopes will help spread its technology across…

Cyber Security Tips (for your Parents)

Today, December 25th, Cloudflare offices around the world are taking a break. From San Francisco to London and Singapore; engineers have retreated home for the holidays (albeit with those engineers on-call closely monitoring their mobile phones). Software engineering pro-tip: Do not, I repeat, do not deploy this week. That is how you end up debugging a critical issue from your parent’s wifi in your old bedroom while your spouse hates you for abandoning them with your racist uncle. — Chris…

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…

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…

Computational method improves the resolution of time-of-flight depth sensors 1,000-fold

For the past 10 years, the Camera Culture group at MIT’s Media Lab has been developing innovative imaging systems—from a camera that can see around corners to one that can read text in closed books—by using “time of flight,” an approach that gauges distance by measuring the time it takes light projected into a scene to bounce back to a sensor. In a new paper appearing in IEEE Access, members of the Camera Culture group present a new approach to…

Xenia: A Domain-specific Framework for Building Optimized SEO Guest Experiences

Co-authors: Ajit Datar, Reza Arbabi, and Chirag Patel   LinkedIn is a network of professionals used by more than half a billion members to meet their professional goals. However, there are even more professionals who are either not on LinkedIn or are registered but don’t realize the full potential of LinkedIn and how the site can help them. Helping our existing and potential members organically discover the power of LinkedIn is an important part of our growth. When it comes…
