Fizzy soda water could be key to clean manufacture of flat wonder material: Graphene — ScienceDaily

Whether you call it effervescent, fizzy, or sparkling, carbonated water is making a comeback as a beverage. Aside from quenching thirst, researchers at the University of Illinois at Urbana-Champaign have discovered a new use for these “bubbly” concoctions that will have major impact on the manufacturer of the world’s thinnest, flattest, and one most useful materials — graphene. As graphene’s popularity grows as an advanced “wonder” material, the speed and quality at which it can be manufactured will be paramount.…

Unpacking the Android Bundle with AutoValue Extensions at Uber Engineering

The Android Bundle is a convenient and sometimes necessary object for wrapping data to pass across process boundaries and send with intents, as well as to store state between configuration changes. Unfortunately, wrapping data in a Bundle often requires repetitive and error-prone code. What makes this even worse is that a Bundle attached to an intent from GCM (Google Cloud Messaging) loses type information because GCM serializes the data as String-String key-value pairs. When investigating a solution for how to…

Researchers discover that fluorescence in ligand-protected gold nanoclusters is an intrinsic property of the gold particles themselves — ScienceDaily

With their remarkable electrical and optical properties, along with biocompatibility, photostability and chemical stability, gold nanoclusters are gaining a foothold in a number of research areas, particularly in biosensing and biolabeling. These gold nanoclusters are chemically protected by ligands, which also steer the binding to biological target molecules. There is still much that researchers don’t know about the luminescent properties of ligand-protected gold nanoclusters, including the origin of their fluorescence. An international research team from Switzerland, Italy, the United States…

$1 billion tower lifts San Francisco skyline to new heights

In this photo taken Saturday, July 22, 2107, the setting sun is reflected on the Salesforce Tower in the San Francisco skyline in this view from Sausalito, Calif. Construction crews are putting the finishing touches on San Francisco’s new tallest building. The 61-story Salesforce Tower and an adjacent transit center represent a shift in San Francisco, one that pits the technology industry against the city’s charming neighborhoods. (AP Photo/Eric Risberg) More than 60 stories above the ground, construction workers climb…

Power outage hits the island of Taiwan. Here’s what we learned.

At approximately 4:50pm local time (8:50am UTC) August 15, a major unexpected power outage hit the island of Taiwan with a significant amount of its power generation facilities going down. Blackout! Most of the island was hit with power outages, shortages and rolling blackouts, with street lights not functioning, nor power in many of Taipei’s shopping malls, and much other infrastructure. Blackouts of this scale are very rare. Usually, during an outage of this scale, it would be expected that…

Cassini says goodbye to a true Titan — ScienceDaily

Mere weeks away from its dramatic, mission-ending plunge into Saturn, NASA’s Cassini spacecraft has a hectic schedule, orbiting the planet every week in its Grand Finale. On a few orbits, Saturn’s largest moon, Titan, has been near enough to tweak Cassini’s orbit, causing the spacecraft to approach Saturn a bit closer or a bit farther away. A couple of those distant passes even pushed Cassini into the inner fringes of Saturn’s rings. Titan will be waiting once again when the…

Evolving API Pagination at Slack – Several People Are Coding

At Slack, the size and scope of the data we expose via our APIs has changed dramatically since the product first launched. Endpoints that were designed around the expectation that they would, in the most extreme cases, return several hundred records, are now returning hundreds of thousands of records. To handle this rapid growth, we’ve had to rethink how we paginate data — from no pagination, to offset pagination, to a new cursor-based pagination scheme. In this post, we’ll go over the…

Best Firefox Add-Ons for Website Designers

There are literally hundreds of Firefox Add-ons out there varying from your local forecast to a chat application. Some are pretty useless but for Web Designers out there, there are a few that, once you get to know them, you won’t know how you’ve managed to work without them. Web Developer Toolbar This one is probably by far the most popular and if you are a Web Designer and don’t have it installed yet, I’m wondering which rock you have…
