    The first cloudless day after Hurricane Harvey made landfall in Houston was Thursday (Aug. 31), and the clearing of the skies gave even greater visibility to the damage and flooding caused by the storm. Below are images of the Houston area by Planet’s satellites captured before the storm, and after it hit.

    Near the Addicks Reservoir

    Neighborhoods near the Addicks Reservoir flooded as the Army Corps of Engineers released water into the Buffalo Bayou. The most obvious signs of flooding in the satellite images are the roads turning from asphalt-grey to a muddy brown.

    Near the Barker Reservior

    A similar situation was captured at Barker Reservoir.

    Along the Buffalo Bayou

    These images show an area about 6 mi² (16 km²), a little downstream from the Barker Reservoir.

    ​It has been 40 years since Quebec adopted its landmark Charter of the French Language — Bill 101 — on Aug. 26, 1977. It was a decision that would forever change the linguistic makeup of Quebec.

    In a collaboration between The Marshall Project and The Upshot, Daniel Lathrop and Anna Flagg analyzed data for 400,000 homicides between 1980 and 2014.

    In almost 17 percent of cases when a black man was killed by a non-Hispanic white civilian over the last three decades, the killing was categorized as justifiable, which is the term used when a police officer or a civilian kills someone committing a crime or in self-defense. Overall, the police classify fewer than 2 percent of homicides committed by civilians as justifiable. The disparity persists across different cities, different ages, different weapons and different relationships between killer and victim.

    There are a lot of visualization methods to choose from, and it can be daunting finding the right visual for your data, especially for those just starting out. The Data Viz Project by ferdio is a work-in-progress catalog that aims to make the picking process a bit easier. Start with a bunch of chart types and filter by things like shape, purpose, and data format. If you’re stuck, this should help get the juices going.

    AMD miner

    A few days ago, AMD released the “Radeon Software Crimson ReLive Edition Beta for Blockchain Compute” driver. According to the release notes on the tech giant’s website, the software optimizes the performance for “Blockchain Compute Workloads,” thereby boosting the efficiency of cryptocurrency mining rigs that are using a GPU for mining (eg., Ethereum mining rigs).

    Currently, the graphics driver can be downloaded from AMD’s official website. The beta software supports desktop GPUs from AMD Radeon HD 7700, and it can be installed on 64-bit Windows 7 (Service Pack 1 or higher required) and 64-bit Windows 10 systems. AMD highlighted in the release notes that the graphics driver is not intended to boost users’ gaming performance. The company added that since this is a beta software, it will not be “supported with further updates, upgrades or bug fixes.”

    AMD’s new beta driver is designed to fix an issue related to the DAG (directed acyclic graph) size. As the number of blocks in the Ethereum blockchain increases (taking roughly 14 seconds to generate a block), so does Ethereum’s epoch (a 100-hour window). For every epoch, or 30,000 blocks, a DAG is generated. As the DAG size grows, the memory requirements for mining Ethereum increase. Since the memory footprint of the

    For the people most immersed in the tech sector, it’s hard to think of a more controversial topic than the ultimate impact of artificial intelligence (AI) on society.

    By eventually empowering machines with a level of superintelligence, there are many different possible outcomes ranging from Kurzweil’s technological singularity to the more dire predictions popularized by Elon Musk.

    Despite this wide gap in potential outcomes, most technologists do agree on one thing: AI will have a profound impact on the society and the way we do business.

    Fascinating: The U.S. economy has finally regained its pre-recession levels of employment and Gross Domestic Product (GDP). What does that mean? More people are getting hired, and they’re spending their paychecks. That’s all good, but it’s no secret the economy has undergone an uneven recovery since the Great Recession. So how does the recovery stack up in different parts…

    A common question asked in the factor investing field is the following -- "how much of the model's performance is driven by sector allocations, and how much is driven by security selection?" Our answer is to simply buy Value stocks or Momentum stocks, regardless of sector constraints. Why? Well a nice anecdote (but not data) is that investing in "cheap" technology stocks was not a great idea in the internet bubble crash.
