4 Must-Use Privacy Tools To Become Untraceable

“I’m a decent person, but I have something to hide” – that is, probably, the expression which describes each of us. The researches show that most of the people do protect themselves on the Internet by combining internal censorship (not sharing undue content) and tech means installing browser ad-blocking and anti-tracking extensions. But what if you could share any content you like and speak up freely? You can, using the following privacy tools. Best Privacy Tools 1. VPN VPN is…

Modeling Uplift Directly: Uplift Decision Tree with KL Divergence and Euclidean Distance as Splitting Criteria

Introduction Uplift models predict the incremental effect of a treatment on the outcome of an individual. In other words, they answer the causal question of how an individual’s behavior will change if we give him/her a specific treatment. At Wayfair, we build uplift models to inform us of whom to target and how much to bid for the display ads we use in display remarketing. To learn more about this specific business use case, check out Wayfair Data Science Manager…

Tales from the Crypt(o team)

Halloween season is upon us. This week we’re sharing a series of blog posts about work being done at Cloudflare involving cryptography, one of the spookiest technologies around. So bookmark this page and come back every day for tricks, treats, and deep technical content. A long-term mission Cryptography is one of the most powerful technological tools we have, and Cloudflare has been at the forefront of using cryptography to help build a better Internet. Of course, we haven’t been alone…

Microscale rockets can travel through cellular landscapes with precision — ScienceDaily

A new study from the lab of Thomas Mallouk shows how microscale “rockets,” powered by acoustic waves and an onboard bubble motor, can be driven through 3D landscapes of cells and particles using magnets. The research was a collaboration between researchers at Penn and the University of San Diego, the Harbin Institute of Technology in Shenzhen, and Pennsylvania State University, where the study was initially conducted, and was published in Science Advances. The origin story of the tiny rockets began…

Comparium: Reliable & Fast Cross-Browser Web Testing App

Have you observed that your website behaves differently on different platforms? Or, do you often get customer feedback mentioning that your website is not working on “Safari” but is running perfectly on “Google Chrome”? This is where cross-browser testing comes into the picture. It involves validating the compatibility of a website/application across different web browsers. The incompatibility is seen because each browser is coded differently and hence they have a different way of interpreting the information contained in a website.…

Experiment with HTTP/3 using NGINX and quiche

Just a few weeks ago we announced the availability on our edge network of HTTP/3, the new revision of HTTP intended to improve security and performance on the Internet. Everyone can now enable HTTP/3 on their Cloudflare zone and experiment with it using Chrome Canary as well as curl, among other clients. We have previously made available an example HTTP/3 server as part of the quiche project to allow people to experiment with the protocol, but it’s quite limited in…

The New Frontier in Global Relations: Cyberspace

Jason Martin, BA ’97, is acting director of the Cyber Development Directorate for the Defense Information Systems Agency. A Mizzou alumnus whose agency is responsible for building out cyber defense capabilities for the U.S. Department of Defense (DoD) says wars of the future will start in cyberspace. Jason Martin, BA ’97, is acting director of the Cyber Development Directorate for the Defense Information Systems Agency (DISA) at Fort Meade, Maryland and the vice director of the Development and Business Center…

Next-generation single-photon source for quantum information science — ScienceDaily

Over the last two decades, tremendous advances have been made in the field of quantum information science. Scientists are capitalizing on the strange nature of quantum mechanics to solve difficult problems in computing and communications, as well as in sensing and measuring delicate systems. One avenue of research in this field is optical quantum information processing, which uses photons — tiny particles of light that have unique quantum properties. A key resource to advance research in quantum information science would…

Cloudflare’s protection against a new Remote Code Execution vulnerability (CVE-2019-16759) in vBulletin

Cloudflare has released a new rule as part of its Cloudflare Specials Rulesets, to protect our customers against a high-severity vulnerability in vBulletin.   A new zero-day vulnerability was discovered for vBulletin, a proprietary Internet forum software. By exploiting this vulnerability, bad actors could potentially gain privileged access and control to the host servers on which this software runs, through Remote Code Execution (RCE). Implications of this vulnerability At Cloudflare, we use three key indicators to understand the severity of…

Molecule links weight gain to gut bacteria — ScienceDaily

UT Southwestern researchers have found a key driver of the crosstalk that helps synchronize the absorption of nutrients in the gut with the rhythms of the Earth’s day-night light cycle. Their findings could have far-ranging implications for obesity in affluent countries and malnutrition in impoverished countries. In the study, published this week by Science, Dr. Lora Hooper and her research team found that the commensal, or good, bacteria that live in the guts of mammals program the metabolic rhythms that…
