Localizing Slack – Several People Are Coding

Localization is so easy! …said no one ever. This week, we launched French, German, and Spanish localization in Slack. I’d like to share some of the lessons learned, tooling, and processes we put in place to complete this project and build localization into our ongoing workflow. Handling Strings The first step in localizing Slack was to prepare the strings in our codebase for localization. While mobile platforms provide clear frameworks for localization that keep strings separate from code, our web…

DAAP grad puts ‘design doing’ into action with new sports lighting system

DAAP grad Barry Hutzel helped design Qualite’s GameChanger, a unique new modular sports lighting system. Credit: Craig Van Der Lende On May 24, 1935, Cincinnati’s Crosley Field illuminated for professional baseball’s first night game. University of Cincinnati alum Earl Payne, Eng. ’26, helped design that revolutionary lighting system—along with the original lighting layout for UC’s Nippert Stadium. More than 80 years later, another UC grad is helping to change the sports lighting game. Barry Hutzel graduated from UC’s College…

Understanding the prevalence of web traffic interception

This is a guest post by Elie Bursztein who writes about security and anti-abuse research. It was first published on his blog and has been lightly edited. This post summarizes how prevalent encrypted web traffic interception is and how it negatively affects online security according to a study published at NDSS 2017 authored by several researchers including the author of this post and Nick Sullivan of Cloudflare. We found that between 4% and 10% of the web’s encrypted traffic (HTTPS)…

Tumblr Engineering — Flow and TypeScript

One of the Core Web team’s goals at Tumblr is to reduce the number of runtime issues that we see in our React codebase. To help move some of those issues from runtime to compile time, I evaluated the two leading type systems, Flow and TypeScript, to see if they could give us more type safety. I did a bit of background reading about the differences between Flow and TypeScript to see what the community had to say about them.…

Study sets new distance record for medical drone transport

Temperature-controlled specimen transport container designed by Johns Hopkins researchers is packed with blood sample test tubes. Credit: Johns Hopkins Medicine Johns Hopkins researchers have set a new delivery distance record for medical drones, successfully transporting human blood samples across 161 miles of Arizona desert. Throughout the three-hour flight, they report, the on-board payload system maintained temperature control, ensuring the samples were viable for laboratory analysis after landing. In a report of the findings, published in the American Journal of Clinical…

Drones help scientists check the health of Antarctic mosses, revealing climate change clues

Mosses are sensitive to even minor changes in their living conditions. Credit: Sharon Robinson, Author provided Drones are helping scientists check the health of Antarctic mosses, revealing clues on the pace of climate change. Mosses are sensitive to even minor changes in their living conditions, and scientists traditionally tramped through difficult terrain to collect data on them. Using the specially-designed drones is faster, kinder to the environment and delivers detailed images that satellite imagery cannot match. Drones also…

Key process to be modernized in production of life-saving drugs, food preservation

Research scientist Nithin Raghunathan works in the LyoHUB Lyophilization Technology Demonstration Facility at the Birck Nanotechnology Center at Purdue University. Credit: Purdue University image/Erin Easterling A consortium of experts is working to modernize a process that is used in making a wide range of products, from freeze-dried space foods to life-saving wonder drugs. The process, called “lyophilization,” removes water at low temperature and pressure. Lyophilization is needed for products that would be damaged if they were dried by heating, but…

Activated Carbon Filter in Water Systems

Granular activated carbon (GAC) is generally utilized for uprooting natural constituents and remaining disinfectants in water supplies. This not just enhances taste and minimizes wellbeing dangers; it secures other water treatment units, for example, reverse osmosis films and particle trade saps from conceivable harm because of oxidation or natural fouling. Actuated carbon is a favored water treatment procedure as a result of its multifunctional nature and the way that it adds nothing hindering to the treated water. Most activated carbons…

Scaling Event Sourcing for Netflix Downloads, Episode 1

by Karen Casella, Phillipa Avery, Robert Reta, Joseph Breuer Early in 2016, several Netflix teams were asked the question: “What would it take to allow members to download and view content offline on their mobile devices?” For the Playback Licensing team, this meant that we needed to provide a content licensing system that would allow a member’s device to store and decrypt the downloaded content for offline viewing. To do this securely would require a new service to handle a…
