Documentation Details Matter – Square Corner Blog – Medium

Not too long ago I joined the Developer Platform team at Square as a product designer. One of the first things I was tasked with was addressing some quick-hit, tactical improvements we could make to our existing site to improve the developer experience. A designer on a developer team? Working on documentation? “Oil and water,” you might say, but quite the opposite. I’ve waded through my fair share of documentation, Stack Overflow posts, and random blogs, teaching myself various languages…

fast JPEG optimization on ARM server

As engineers at Cloudflare quickly adapt our software stack to run on ARM, a few parts of our software stack have not been performing as well on ARM processors as they currently do on our Xeon® Silver 4116 CPUs. For the most part this is a matter of Intel specific optimizations some of which utilize SIMD or other special instructions. One such example is the venerable jpegtran, one of the workhorses behind our Polish image optimization service. A while ago…

Building robots, building the future

Hosted by MU’s Neural Engineering Laboratory, the 13th annual Robotics Design Challenge welcomed 325 participating K-8th graders to test the robots they had spent months creating. Photo by Brandan Haskell. On April 7, the classrooms of Naka Hall filled with aspiring robotics designers from elementary and middle schools across the state. Hosted by MU’s Neural Engineering Laboratory, the 13th annual Robotics Design Challenge welcomed participating K-8th graders to test the robots they had spent months creating. According to engineering student…

Mizzou NSBE lands impressive accolades at Annual National Conference

Mizzou NSBE was named Region V Medium Sized Chapter of the Year for chapters with less than 75 members, taking top honors in a region that includes much of the Midwest, along with Mexico, Central and South America, South Africa and the Dominican Republic. The chapter also won the National T.O.R.C.H. (Technical Outreach and Community Help) Chapter of the Year for their work in the Columbia community and had two members elected to regional leadership — Nosakhare Eke (Region V…

Researchers conduct first-ever combustion experiment with X-rays

Inside a gas turbine engine’s combustor, scientists use the world’s strongest X-ray source at the Advanced Photon Source at Argonne National Laboratory to peer inside formally unseen processes. Credit: U.S. Army photo by David McNally The U.S. Army Research Laboratory’s Center for Unmanned Aircraft Systems Propulsion made an historic first with its experiment in a gas turbine combustor using X-rays. The data will help advance gas turbine engine designs for higher power density and efficiency, scientists said. “This is the…

Risk-based optimization scheme boosts confidence and profitability for future mixed-technology power plants

The challenge is the optimization of operations and electricity market participation for a VPP comprising a thermal unit, such as a conventional gas-fired power plant, a wind farm and a pumped storage hydro unit for energy storage. Credit: Xavier Pita A scheme to balance risks may help realize the benefits of being able to combine complementary power technologies, such as thermal generation, wind power and energy storage. Such benefits include lower capital costs and more responsive and reliable energy delivery…

Technique strengthens buildings using wood waste

Credit: National University of Singapore Researchers from the National University of Singapore (NUS) have found an innovative and environmental-friendly technique to enhance building structures. The new method, which incorporates biochar recycled from saw dust into cement, improves the strength and water tightness of mortar and concrete, and offers an alternative use to the large volume of wood waste produced in Singapore. Wood waste from furniture factories makes up a huge portion of waste generated in Singapore. In 2016 alone, more…

Engineers propose coordinated control to assist drivers

Engineers have proposed a coordinated control architecture for motion management in advanced driver assistance systems (ADAS) to increase safety and comfort across all vehicles, regardless of ADAS specifics. They published their proposal in IEEE/CAA Journal of Automatica Sinica, a joint publication of the IEEE and the Chinese Association of Automation. “The modern automobile is a complex system of systems. How the functionalities of advanced driver assistance are implemented and coordinated across the systems of the vehicle is generally not…

Scientists develop haptic interface with seven degrees of freedom

Haptic interfaces allow humans to handle dangerous or delicate materials. From laparoscopic surgery to radioactive waste removal to the simple act of putting a mobile on vibrate, robotics are getting touchy. Now, researchers from the Chinese Academy of Sciences have developed an even more expansive haptic interface that allows for seven degrees of movement. The most common haptic interfaces typically have three degrees of movement. The research findings were published on the January 10th issue of IEEE/CAA Journal of Automatica…

A Tour of Duty at the U.S. Digital Service

Every month, Square Engineers give lightning talks internally. We’re excited to share some of our favorites! Zach talks about working with the USDS, some of their core values, and his work on login.gov. In learning about the values of the USDS, we can see how the government aims to better serve people in the future as we become more reliant upon the internet and digital services. Source link…
