Cards Saved with Square’s Card on File Now Automatically Update When They Expire

With Card Updater, we now automatically refresh expired cards so you never miss a sale with your recurring customers. Many of our e-commerce developers and merchants have quickly adopted our Card on File capability. It’s a great way to build stronger relationships with buyers and tremendously simplifies the buying process for recurring customers. However, there is nothing more frustrating for an e-commerce merchant (or a buyer) than declining a recurring payment because of an expired card, and then missing out…

PWA and Data Visualization talks by Iuliia Konivetska |

I’m super thrilled to announce that I’ll be representing Wayfair at 2 major conferences this year: CSS Dev Conference and the Strange Loop! My new talk “Light Speed Web with Progressive Web Apps” , which I present October 9 in New Orleans at , will cover the basics of PWA, the UX aspect of PWA, and the heavy duty hands on coding magic of Web Sockets and Push Notifications.At the Strange Loop, this September at St. Louis MO, I will give a…

The Science of Quality Growth

Analyses and A/B testing shows that increasing our Quality Signup rate causes an increase in our long-term engagement rate.   The concept of a custom true-north metric is not unique to LinkedIn. In fact, many other companies have similar measures that serve as their true-north metric for growth. For example, Facebook is known to track users who connect with 10 friends in seven days. Pinterest tracks Weekly Active Repinners. And Slack tracks teams who have sent 2,000 messages. For the…

Visual Search with Deep Learning |

Search has long been an essential tool for Wayfair that enables users to discover products among millions. While we offer great text and faceted search, those features can only go so far. It can be difficult to precisely describe an item in mind, especially in a way search engines can understand. But there’s one type of search query that’s very explicit, specific, and interesting – an image that you upload from your phone, after you snap something in the real…

Proposed Regulatory Text for New Post-Tensioning OSHA Regulations

The following is an bridged version of the proposed regulatory text for the new post-tensioning OSHA Regulations as reported by Ironworkers.org (Sections #1, 6 and 9 relate to the post-tensioning activities). The controlling contractor shall ensure that the following is provided and maintained: (1)   Adequate access roads into and through the site for the safe delivery and movement of derricks, cranes, trucks, other necessary equipment, and the material to be erected and means and methods for pedestrian and vehicular control.  Exception: …

A marker-free system for tracing mass components

With its “Track & Trace Fingerprint“ Fraunhofer IPM has developed a marker-free system for the traceability of mass components. Credit: Fraunhofer IPM Highly interconnected manufacturing chains, cost issues and technical feasibility make it difficult to trace individual components in mass production. Efficient “track & trace” solutions are, however, an important prerequisite for production and process optimization—especially in the context of digitized manufacturing. With its “Track & Trace Fingerprint” solution, the Fraunhofer-Institute for Physical Measurement Techniques IPM in Freiburg, Germany, has…

Sensor boutique for early adopters

Credit: Photo Fraunhofer IAF Every chemical substance absorbs a very individual fraction of infrared light. Like a human fingerprint, this absorption can be used with optical methods for identifying substances. Such methods are used in the chemical industry, for example, but also in the health sector or in criminal investigation. If a company plans a new project, it often needs individually tailored…

Avoiding material inclusions such as dross in wind turbines

To ensure these giants can reliably generate electricity for many years to come, the iron processing industry must manufacture their massive components in a stable, resource-saving and yet cost-effective way. However, material inclusions such as dross are often unavoidable while casting. Fraunhofer researchers are currently working to detect and analyze such material…

Single cells lined up like ducks in a row

The new microhole chip can be populated with 200,000 single cells, each held in place in separate holes. Credit: Fraunhofer IBMT The higher the concentration of tumor cells in the bloodstream, the greater the risk of metastasis. The number of circulating tumor cells indicates how well a patient is responding to therapy. Fraunhofer researchers have developed a new microhole chip that enables cells to be identified and characterized reliably within minutes. The conventional method of FACS analysis (fluorescence-activated cell sorting)…
