YouTube for Android gets a major makeover so you can minimize videos while browsing and searching - TechCrunch

Google today started rolling out a major new version of YouTube for Android. This update is one of the most important for the service in a long time, introducing a cool in-app multitasking feature that allows you to minimize the screen while browsing channels or doing searches. It also features Google’s standard “map” interface.

Until now, viewers had to stop the video. In this new version, the video will simply move to the bottom right corner of the screen and continue playing. From there, you can always go back to full screen mode or just swipe right or left to close the video.

33_Screenshot_Nexus4_ENThis new “picture-in-picture” feature is the highlight of today’s release, but the YouTube team has also added a number of other new features. For example, you can now more easily search channels and browse for playlists to watch collections of videos sequentially.

With the recent launch of Google Chromecast, it’s no surprise that the company has added deeper integration with the new YouTube app. This means you will now see a preview screen on your device while a video is playing on Chromecast or any other smart TV that supports this feature. This should make it easier to queue up the next video.

It’s not clear when this update will hit iOS, but a Google representative told me it’ll be coming to all platforms soon.

The update should be rolling out to all Android devices soon. If you can’t wait, the good folks at Android Police will links to the APK for your download pleasure.

Dual polarization weather radar protects us every day

On a lazy Sunday morning, I asked my Twitter followers what they would like me to write about in this space. Andrew Hatter suggested I do something on dual-polarization radar. Going through my previous articles from the past 5 years, I really hadn’t written much about it. That’s my fault, everyone. Dual polarization is a critical tool of the National Weather Service and is used daily to protect us.

First I need to give a little “weather radar 101”. Many of us teaching weather radar often cite Radio Detection and Ranging (RADAR) as a byproduct of World War II. During that time, it became very apparent that annoying “precipitation-related” noise on radar was hampering the radar’s intended military needs. However, the National Weather Service website points out that “the fundamental principle underlying all radars was first observed in 1886 by the physicist Heinrich Hertz when he discovered that electromagnetic waves could be reflected off various objects and even into beams could be focused by appropriate reflectors.” For a deep dive into the history of weather radar, visit this clutch.

At this point, I want to fast-forward to the 1950s. The WSR-57 radar system was adopted by the United States Weather Bureau and the US Navy. This was an S-band (~10 cm wavelength) system that has been the backbone of US radar weather monitoring for over 30 years. It evolved from an experimental X-band system. In the 1970s, the WSR-74 system came into use. At this point, some readers might say, “What the hell are you talking about Dr. Shepherd with all this talk about alphabet soup?

Weather radars send a pulse of microwave energy into the clouds. Some of that energy is scattered back to the radar from the volume of scattering (raindrops, hailstones, insects, and so on). The different frequencies commonly used in radar meteorology are shown in the image above. For example, the S band frequencies are less prone to attenuation than bands with lower wavelengths and have a longer range. If you have satellite TV, you know what attenuation is when it rains hard and your signal is lost.

About the time I entered college in the late 1980s, the National Weather Service, the Department of Defense, and other partners upgraded the U.S. weather radar network to the WSR-88D “S” band system. This was part of the Modernizing the National Weather Service effort in the early 1990s. These radars introduced the life-saving ability of Doppler-shifted phases. Since we know the phase (shape, position, shape, frequency) in which the radar beam was emitted, as scatterers (raindrops, etc.) move will shift the phase of the returning radar echo. From that information we can deduce the speed towards or away from the radar (radial speed is not a real wind speed by the way). This Doppler effect also explains why the pitch of the train’s horn sounds different as it approaches and moves away from you. With such information, meteorologists can now detect rotation in storms that could indicate a tornado. In fact, most tornado warnings today are based on Doppler radar identification. My master’s degree involved using early WSR-88D radar data to track and locate landfall hurricanes.

Okay, we’ve finally reached dual polarization. According to NOAA website“Dual-polarimetric radar transmits and receives pulses in both horizontal and vertical directions.” This means that the returned echoes contain information in both directions about the raindrops, snowflakes, sleet and hailstones. Better information about the shape, size and composition of the targets allows for better discrimination of the type of precipitation (e.g. is it heavy rain or hail? or is it snow or icy rain?) There are even products that can be derived from dual-polarization radar that can help identify tornado-related debris in real time and improve rainfall estimation.

The National Weather Service began the transition to dual-polarization radar in early 2010. According to the National Weather Service, the first upgraded “dual-pol” system (NWS WSR-88DP) at Vance Air Force Base near Enid, Oklahoma. Since this installation in 2011, the National Weather Service has upgraded more than 150 operational radars in the US and its territories.

The image above is a good example of how dual polarization products (correlation coefficient (CC) and differential reflectivity (ZDR) supplemented standard reflectivity products and Doppler rotational patterns (SRM) to confirm that the radar sampled tornado debris thrown into the air. below illustrates how dual polarization radar helped forecasters better determine the location of rainfall versus snowfall in New York.

Trump Accidentally Releases Statement Destroying His Own 'Dumb' Election Lies

The twice-indicted former President Donald Trump made a brief statement Saturday night that appeared to inadvertently disprove his own long-running (and false) claim that the 2020 election had been stolen from him. “Anyone who doesn’t think there was no mass voter fraud in the 2020 presidential election is either very stupid or very corrupt!” read the statement.

Trump’s (apparently) coincidental double-negative means the opposite of what Trump and countless conservatives have falsely claimed about the 2020 presidential outcome. During the end of his presidency, Trump led a failed, anti-democratic and sometimes deadly GOP crusade based on allegations of electoral fraud, to try to undo Joe Biden’s 2020 victory. Trump and several figures in the Republican Party have continued to push these lies in their efforts to conduct an increasing number of election and voting campaigns across the country.

Trump spokespersons did not respond to messages Saturday seeking clarification as to whether the ex-president and current GOP leader meant the opposite of what he said in his written statement, or whether Trump actually admitted that he was either incredibly stupid or was astonishingly corrupt.
