Manufacture of high performance soft magnetic materials by melt spinning

Credit: FIUBA The methodology is to design a master alloy with different starting compositions, to which Fe is added to get the desired atomic ratio of components. With this starting alloy, using the method of melt spinning, are achieved amorphous ribbons (FeSiB) with desired soft magnetic behavior. Then these ribbons are thermally treated for achieve nanocrystalline structures to improve the performance in the magnetic cores. The application of soft magnetic materials in the electrical or electronic industry has increased significantly…

Version 2.5.1 of our Client SDKs – Square Corner Blog – Medium

The holidays aren’t here just yet, but with all these releases it might feel like Christmas! We’re always working to expand our APIs and client libraries to give developers the tools they need to build their integrations with Square businesses. Here’s what’s new in our most recent version (2.5.1): A new field (ordinal) was added to the CatalogItemVariation model. The ordinal is the order in which the item is displayed for the Square Point of Sale App. The location model…

Namespacing Actions for Redux – Kickstarter Engineering

Constraints In this way, the first level of research allowed us to flesh out what requirements a successful solution would support. We needed a way to namespace actions that: Did not involve using local state Worked with combineReducers Could be applied programmatically Had a low–API surface area, which is to say, did not ask to much of others using the resultant component The RFC With these constraints in mind, we identified three solutions: nested reducers, higher-order reducers, and the module…

SCOTUS Wanders into Patent Troll Fight

Next Monday, the US Supreme Court will hear oral arguments in Oil States Energy Services, LLC vs. Greene’s Energy Group, LLC, which is a case to determine whether the Inter Partes Review (IPR) administrative process at the US Patent and Trademark Office (USPTO) used to determine the validity of patents is constitutional. The constitutionality of the IPR process is one of the biggest legal issues facing innovative technology companies, as the availability of this process has greatly reduced the anticipated…

Architecting Uber Support with Customer Obsession Engineering

As Uber grows at scale, addressing support issues for riders and drivers quickly and with as little friction possible is foundational to our ability to create more magical experiences for our users. With this goal in mind, Uber’s Customer Obsession Engineering team is dedicated to improving this element of the Uber experience by developing in-app support, self-service flows, and other technologies that make ticket resolution faster and more seamless. In this article, we discuss our motivations behind building these solutions,…

Making it easier to contribute to Netflix OSS – Netflix TechBlog – Medium

by Travis McPeak and Andrew Spyker Contributing to open source software can be a very rewarding experience that creates opportunities to learn about new problems and technologies, apply problem solving skills, meet and work with new people, and join a community pursuing a common goal. Getting started can also be confusing and full of questions: What should you start working on? Who do you ask for help or direction? What kind of style expectations do the maintainers of the project…

Screaming Circuits: Minimalist Market Segmentation

As an engineer entrepreneur, you’ve probably heard the phrase “market segmentation.” If you haven’t, you really should have, and, well… now you have. It is one of the more important components of marketing. Like many others, it can seem intentionally obscure and overly complex. If we look it up in Wikipedia, we get this: Market segmentation is a marketing strategy which involves dividing a broad target market into subsets of consumers, businesses, or countries that have, or are perceived to…

Photocrosslinkable, thermoreversible, type-I collagen bioink for photolithographic printing

Bioprinting of collagen methacrylamide (CMA) scaffolds. Credit: Dr. David Shreiber A group of biomedical engineers from Rutgers, The State University of New Jersey have leveraged a unique combination of properties of methacrylated collagen to demonstrate its potential as a bioink capable of simple, photolithographic printing of 3D scaffolds for tissue engineering and regenerative medicine. Type-I collagen is the most ubiquitous protein in the human body. Chief among the fibril forming collagens, type-I collagen gives many soft tissues strength and structure.…

Will Tesla’s Electric Semis Take Over?

Elon Musk’s latest product unveiling, held last week in Hawthorne, California, was done in the accepted fashion of introducing a new product these days, which is for the CEO to stand alone on a stage, backed by giant screens and, if possible, a piece of the subject hardware too.  Musk claimed that the new electric truck he plans to start building in a year or so will travel 500 miles on a single charge.  Critics cited in the New York…

Autoscaling Pub/Sub Consumers | Labs

Spotify’s Event Delivery system is responsible for delivering hundreds of billions of events every day. Most of the events are generated as a response to a user action, such as playing a song, following an artist or clicking on an ad. All in all, more than 300 different types of events are being collected from Spotify clients. The Event Delivery system is one of the core pillars of Spotify’s data infrastructure since almost all data processing depends, either directly or…
