Solving Manageability Challenges with Nuage

Matrix: The columns representing Service1..N denote LinkedIn’s large-scale services like Kafka, Samza, Ambry, Venice, Espresso, etc. Each of the rows in the matrix represents a generic feature that the Nuage team has built to efficiently manage such massive systems.   Let’s dive deeper into some of the generic features that we have abstracted out and built in the last few years. These features by themselves are scalable, fault-tolerant, adaptable, cross-service pluggable, and used extensively within LinkedIn by product teams. Resource provisioningNuage…

How Slack Built Shared Channels

By Yingyu Sun and Mike Demmer, with contributions from the Shared Channels Team Slack was originally built to be the collaboration hub for the work within your company. As the network of companies using Slack for internal work grew, we saw the value of allowing different companies to collaborate together in one channel. We’re now making shared channels available to all customers! A shared channel is one that connects two separate organizations. You no longer need to go back and…

Facing Google In Your Living Room

An article on cnet.com recently described how Google’s new smart assistant, called Google Nest Hub Max, uses facial recognition technology to tell who is talking with it.  This feature has raised privacy concerns, as Google has admitted that they reserve the right to upload facial data from it to the cloud to help improve “product experience.”  But whatever Google does legitimately, a hacker might be able to do too, and so we are approaching a time when the telescreens of…

How To Design Innovative Electronic Devices That Sell

Today’s technologically advanced market offers electronics engineers a seemingly never-ending amount of customers. The number of electronics available on the market has exploded from laptops and computers to smaller devices like tablets. For this reason, numerous tech enthusiasts are working to design electronic devices that they can sell. If you are a tech enthusiast who wants to take advantage of the opportunities the technology industry offers entrepreneurs, you need to learn about creating your own electronic devices.

Wayfair DS Explains It All: Ilkay Yildiz on Learning From Comparisons

Stylistic preference is an important factor when a home goods customer is deciding which product to buy, but it is very difficult to identify and define. Although designers have established different style categories, labeling a scene as adhering to a particular style is a highly subjective task. Furthermore, customers often cannot verbalize their style preferences, but can identify their preferences by looking at images. Thus, it is crucial to show products in a room context that are tailored to a…

Predicting risk of heart failure for diabetes patients with help from machine learning — ScienceDaily

Heart failure is an important potential complication of type 2 diabetes that occurs frequently and can lead to death or disability. Earlier this month, late-breaking trial results revealed that a new class of medications known as SGLT2 inhibitors may be helpful for patients with heart failure. These therapies may also be used in patients with diabetes to prevent heart failure from occurring in the first place. However, a way of accurately identifying which diabetes patients are most at risk for…

Sensor is poised to improve landmine detection and non-destructive testing — ScienceDaily

Detecting landmines can be a challenging and slow process. Detecting them from a moving vehicle would make the process more speedy, but at the expense of accuracy. At the Optical Society’s (OSA) Laser Congress, held 29 September — 3 October 2019 in Vienna, Austria, researchers from the University of Mississippi, U.S.A., will report a new laser-based sensor that effectively detects buried objects even while the detector is in motion. This new device offers a significant improvement over existing technologies, which…

Biologists say visualization of an essential mitotic pathway in living animal cells is a first — ScienceDaily

Cell biologist Thomas Maresca and senior research fellow Vikash Verma at the University of Massachusetts Amherst say they have, for the first time, directly observed and recorded in animal cells a pathway called branching microtubule nucleation, a mechanism in cell division that had been imaged in cellular extracts and plant cells but not directly observed in animal cells. Details appear this month in the Journal of Cell Biology. In this work supported by NIH’s National Institute of General Medical Sciences,…

How Cloudflare and Wall Street Are Helping Encrypt the Internet Today

Today has been a big day for Cloudflare, as we became a public company on the New York Stock Exchange (NYSE: NET). To mark the occasion, we decided to bring our favorite entropy machines to the floor of the NYSE. Footage of these lava lamps is being used as an additional seed to our entropy-generation system LavaRand — bolstering Internet encryption for over 20 million Internet properties worldwide. (This is mostly for fun. But when’s the last time you saw…

Paramagnetic spins take electrons for a ride, produce electricity from heat — ScienceDaily

An international team of researchers has observed that local thermal perturbations of spins in a solid can convert heat to energy even in a paramagnetic material — where spins weren’t thought to correlate long enough to do so. This effect, which the researchers call “paramagnon drag thermopower,” converts a temperature difference into an electrical voltage. This discovery could lead to more efficient thermal energy harvesting — for example, converting car exhaust heat into electric power to enhance fuel-efficiency, or powering…
