  1. First released with the very first version of Windows 1.0 in 1985, Paint in its various guises would be one of the first graphics editors used by many and became a core part of Windows. Starting life as a 1-bit monochrome licensed version of ZSoft’s PC Paintbrush, it wasn’t until Windows 98 that Paint could save in JPEG. With the Windows 10 Creators Update, released in April, Microsoft introduced the new Paint 3D, which is installed alongside traditional Paint and features 3D image making tools as well as some basic 2D image editing. But it is not an update to original Paint and doesn’t behave like it. Now Microsoft has announced that, alongside Outlook Express, Reader app and Reading list, Microsoft Paint has been signalled for death having been added to the “features that are removed or deprecated in Windows 10 Fall Creators Update” list. Falling under the deprecated column for apps that are “not in active development and might be removed in future releases”, Microsoft Paint’s ticket has been called and now it’s only a matter of time before it is removed like your favourite piece of old furniture from your childhood home. Paint was never one of the most capable apps, and was limited to the bitmap (BMP) and PCX formats until 1998, but if you wanted to scribble something out using your mouse or make a quick cut and paste job, Paint was always there, even on work computers. The most recent version of Paint for Windows 7 and later was much improved, but still considered feature poor compared to other free alternatives such as the third-party Paint.NET. When Microsoft Paint will officially be removed from Windows has yet to be confirmed, while a precise date for the release of the Windows 10 Autumn Creators Update is equally up in the air. Whether, like Clippy, Windows users will celebrate or decry Paint’s removal, it will be a moment in the history of Windows as one of its longest-standing apps is put out to pasture.

  2. Map of Global Lightning

    Need to know where to go in order to get hit by lightning more than once? NASA has the answer for you. Based on data collected from 1998–2013 by the Lightning Imaging Sensor (LIS) on NASA’s Tropical Rainfall Measuring Mission satellite, and from 1995–2000 by the Optical Transient Detector (OTD) on the OrbView-1/Microlab satellite, a global map showing the lighting flash rate (number of flashes per kilometer per year) was created. Based on satellite observations, researchers found that lightning occurs more frequently over land than it does ocean: “The higher frequency of lighting over land makes sense because solid earth absorbs sunlight and heats up faster than water; this means there is stronger convection and greater atmospheric instability, leading to the formation of thunder and lightning producing storms.” As a year round average, Central Africa and Northwestern South America experience the most lightning strikes. The Brahmaputra Valley of far eastern India experiences a high number of strikes during the month of May due the unstable heating and weather patterns that occur before the onset of the Monsoons. The highest amounts of lightning flashes occur in the far eastern Democratic Republic of Congo, and Lake Maracaibo in northwestern Venezuela. The global maps shows the average density of lightning strikes per square kilometer based on data from 1995 to 2013. Areas of low lightning strikes are shaded gray and purple. The areas with the most strikes are bright pink (as many as 150 per year per square kilometer. https://earthobservatory.nasa.gov/IOTD/view.php?id=85600&eocn=image&eoci=moreiotd
  3. Drought and flash drought­ rank second in terms of national weather-related economic impacts behind hurricanes, with annual losses nearing $9 billion in the United States, according to the National Oceanic and Atmospheric Administration. To provide earlier detection, the Quick Drought Response Index, or QuickDRI, went operational in June 2017 as a weekly drought alarm, providing improved sensitivity to early-stage drought conditions and rapidly evolving drought events. “QuickDRI fills a gap in drought monitoring because of its sensitivity to short-term changes,” said Jesslyn Brown, a project co-investigator and lead for QuickDRI operations at the U.S. Geological Survey. “We expect it to be especially helpful for decisions related to irrigation and fire management.” Like its companion Vegetation Drought Response Index, or VegDRI, which portrays drought’s effect on vegetation conditions, QuickDRI relies on a number of remotely-sensed indicators. Decades of satellite data housed at the USGS Earth Resources Observation and Science, or EROS, Centerprovide a resource for assessing abnormal vegetation and climate conditions over a longer historical period. However, VegDRI is a seasonal drought indicator. As a geospatial tool to detect even faster-moving droughts, QuickDRI evolved to detect drought’s effects much more quickly. “Preliminary assessment of QuickDRI shows that it consistently detects short-term dryness patterns across the continental U.S.,” said Dr. Brian Wardlow, the co-principal investigator of the QuickDRI project and director of the Center for Advanced Land Management Information Technologies at the University of Nebraska-Lincoln. QuickDRI uses a variety of weekly inputs, including: A Soil Moisture Anomaly, which models soil moisture, from the NASA/NOAA North American Land Data Assimilation System; The Evaporative Stress Index, which is produced by the U.S. Department of Agriculture and shows evaporative moisture loss from plants; The Standardized Vegetation Index, based on a weekly Normalized Differentiated Vegetation Index (NDVI) that gauges plant vigor compared to historical norms; The Standardized Precipitation Index, an indicator of monthly precipitation as compared to normal; and Landscape characteristics such as soil texture, land cover and elevation. see here : https://vegdri.cr.usgs.gov/ or http://quickdri.unl.edu/
  4. A new research mission is being launched in order to continue to add to our knowledge of the seas, including expanded efforts to map the sea floor. NASA, NOAA, the French Space Agency Centre National d’Etudes Spatiales, and the European Organization for the Exploitation of Meteorological Satellites are using their joint Jason-2 satellite for the project. The satellite was first used with these organizations for the Ocean Surface Topography Mission. Jason-2 has been in orbit for nine years and has regularly tracked the rise and fall of the ocean’s surface levels, in addition to gathering other important ocean metrics. The Ocean Surface Topography Mission (OSTM)/Jason-2 satellite, a partnership among NASA, the National Oceanic and Atmospheric Administration (NOAA), the French Space Agency Centre National d’Etudes Spatiales (CNES) and the European Organisation for the Exploitation of Meteorological Satellites (EUMETSAT), marked its ninth year in orbit on June 20. Designed to fly three to five years, OSTM/Jason-2 has now completed more than 42,000 trips around our planet, contributing to a database of satellite altimetry that dates back to the launch of the U.S./French Topex/Poseidon satellite in 1992. Over the past nine years, OSTM/Jason-2 has precisely measured the height of 95 percent of the world’s ice-free ocean every 10 days. Since its launch in June 2008, it has measured a 1.6-inch (4-centimeter) increase in global mean sea level, which has been rising at a rate of about 0.12 inches (3 millimeters) a year since satellite altimetry records began in 1993. It has also tracked changes in regional sea level; monitored the speed and direction of ocean surface currents; enabled more accurate weather, ocean and climate forecasts; and observed multiple El Niño and La Niña events. Since October 2016, it has operated in a tandem mission with its successor, Jason-3, launched in January 2016, doubling coverage of the global ocean and improving data resolution for both missions. But as OSTM/Jason-2’s onboard systems age and key components begin to show signs of cumulative space radiation damage, it has become prudent to move the older satellite out of its current shared orbit with Jason-3. On June 20, Jason-2’s four mission partner agencies agreed to lower Jason-2’s orbit by 17 miles (27 kilometers) in early July, from 830 to 813 miles (1,336 to 1,309 kilometers), placing it in a new orbit with a long repeat period of just more than one year. The move is designed to safeguard the orbit for Jason-3 and its planned successor, Jason-CS/Sentinel-6, planned for launch in 2020. In its new orbit, OSTM/Jason-2 will also undertake a new science mission. The long-repeat orbit will allow OSTM/Jason-2 to collect data along a series of very closely spaced ground tracks just 5 miles (8 kilometers) apart. The result will be a new, high-resolution estimate of Earth’s average sea surface height. The shape of the sea surface is partly determined by underwater hills and valleys, which pull the water due to the force of gravity. Scientists will use these new OSTM/Jason-2 data to improve maps of the shape and depth of the sea floor, resolving many presently unknown seamounts (underwater mountains) and other geologic features on the ocean bottom. These new maps will permit advances in ocean modeling, tsunami wave forecasting, and naval operations support, and will boost understanding of the dynamics of the solid Earth. The data will also help prepare for the next generation of global satellite altimetry missions, including the NASA/CNES/Canadian Space Agency/UK Space Agency Surface Water and Ocean Topography (SWOT) mission, planned for launch in 2021; and Sentinel-3B, to be launched by the European Space Agency in early 2018. "It's still too early for OSTM/Jason-2 to sail off into the sunset,” said OSTM/Jason-2 and Jason-3 Project Scientist Josh Willis of NASA’s Jet Propulsion Laboratory in Pasadena, California. "The ocean covers more than 71 percent of Earth’s surface, so improving our knowledge of the shape of the sea floor is like mapping a whole new world. These new data will also help pave the way for satellite altimetry missions that don't need to follow traditional satellite ground tracks." While OSTM/Jason-2 is leaving its old orbit, data from its new orbit will continue to be used by operational agencies to provide societal and strategic benefits ranging from deriving ocean currents and improving marine, fishery and naval operations; to assisting in forecasting the intensity of tropical hurricanes and cyclones by identifying regions of high thermal energy in the ocean. source : https://www.nasa.gov/feature/jpl/veteran-ocean-satellite-to-assume-added-role see here : https://sealevel.jpl.nasa.gov/
  5. Klencke Atlas Online

    The Klencke Atlas is one of the world's biggest: it measures 176 x 231 cm when open. It takes its name from Joannes Klencke, who presented it to Charles II on his restoration to the British thrones in 1660. Its size and its 40 or so large wall maps from the Golden Age of Dutch mapmaking were supposed to suggest that it contained all the knowledge in the world. At another level, it was a bribe intended to spur the King into granting Klencke and his associates trading privileges and titles. Charles, who was a map enthusiast, appreciated the gift. He placed the atlas with his most precious possessions in his cabinet of curiosities, and Klencke was knighted. Later generations have benefited too. The binding has protected the wall maps which have survived for us to enjoy - unlike the vast majority of other wall maps which, exposed to light, heat and dirt when hung on walls, have crumbled away. visit : https://www.bl.uk/collection-items/klencke-atlas

    welcome
  9. urns out WiFi is good for more than just sharing cat GIFs with your friends. Researchers at the Mostofi Lab at UC Santa Barbara have created a system that "sees" inside buildings using two drones and WiFi. To pull this off, the drones are each equipped with WiFi transceivers and fly in tandem outside the target building. One of the UAVs then transmits a WiFi signal while the second one reads the corresponding received power. Throw in a bunch of advanced math and the data is translated into a 3D image of the internals of the building with some impressive results. The Mostofi Lab is no stranger to using radio waves to penetrate walls. In 2010 it published its first demonstration of imaging using WiFi. "However, enabling 3D through-wall imaging of real areas is considerably more challenging due to the considerable increase in the number of unknowns," professor Yasamin Mostofi told UCSB's The Current. This research could help emergency response teams do sweeps of buildings without putting first responders in unnecessary danger. The lab also noted it could be used for archaeological and structural monitoring. source : https://www.engadget.com/2017/06/19/researchers-map-a-building-in-3d-using-wifi-enabled-drones/
