The Growing Case for Geoengineering 

David Mitchell pulls into the parking lot of the Desert Research Institute, an environmental science outpost of the University of Nevada, perched in the dry red hills above Reno. The campus stares over the tops of the downtown casinos into the snow-buried Pine Nut Mountains. On this morning, wispy cirrus clouds draw long lines above the range.Mitchell, a lanky, soft-spoken atmospheric physicist, believes these frigid clouds in the upper troposphere may offer one of our best fallback plans for combating climate change. The tiny ice crystals in cirrus clouds cast thermal radiation back against the surface of the earth, trapping heat like a blanket—or, more to the point, like carbon dioxide. But Mitchell, an associate research professor at the institute, thinks there might be a way to counteract the effects of these clouds.It would work like this: Fleets of large drones would crisscross the upper latitudes of the globe during winter months, sprinkling the skies with tons of extremely fine dust-like materials every year. If Mitchell is right, this would produce larger ice crystals than normal, creating thinner cirrus clouds that dissipate faster. “That would allow more radiation into space, cooling the earth,” Mitchell says. Done on a large enough scale, this “cloud seeding” could ease global temperatures by as much as 1.4 °C, more than the planet has warmed since the Industrial Revolution, according to a separate Yale study.

New Part Day: Very Cheap LIDAR 

Self-driving cars are, apparently, the next big thing. This thought is predicated on advancements in machine vision and cheaper, better sensors. For the machine vision part of the equation, Nvidia, Intel, and Google are putting out some interesting bits of hardware. The sensors, though? We’re going to need LIDAR, better distance sensors, more capable CAN bus dongles, and the equipment to tie it all together.This is the cheapest LIDAR we’ve ever seen. The RPLIDAR is a new product from Seeed Studios, and it’s an affordable LIDAR for everyone. $400 USD gets you one module, and bizarrely $358 USD gets you two modules. Don’t ask questions — this price point was unheard of a mere five years ago.

How To Export Bookmarks From Chrome? 

Chrome already allows its user to sync their bookmarks and other things across devices using their Google account.For some reason, if you don’t want to enable device sync in Google Chrome, you can still use Chrome’s inbuilt bookmark export feature. It will help you export bookmarks from Chrome in an HTML file and transfer them to Chrome on another device.Also Read: How To Connect Apps To Google Drive? How To Manage Google Drive Apps?How to export bookmarks from Chrome?Open Google Chrome on your computer.Open Bookmarks Manager by using the CTRL+SHIFT+O shortcut. Alternatively, you can go to More Options Menu (three vertical dots)>Bookmarks>Bookmarks Manager.In Bookmarks Manager page, click Organize drop-down menu.Click Export bookmarks to HTML file.Choose the desired name and location for the file and click save.Now, you can use this file to export bookmarks from Chrome to another device running Chrome browser. The file also retains the folders in which your bookmarks are divided. Also, you can simply open the HTML file in your browser and access the bookmarks from there.

Report: Google will add an ad blocker to all versions of Chrome web browser 

The Wall Street Journal just dropped a shocker of a report: Google, the biggest Web advertising company in the world, is planning to build an ad blocker into Google Chrome, the world’s most popular Web browser. The ad blocker will reportedly end up in the desktop and mobile versions of Chrome and would be switched on by default.If true, this report suggests a major conflict of interest for Google. Today Chrome covers over 50 percent of the browsing market, according to Net Market Share, and Google would kill its income if it started blocking Google ads. Of course, Google won’t block Google ads. Instead, according to the report, Chrome will target “unacceptable ads” as defined by the Coalition for Better Ads. The Coalition for Better Ads, which counts Google and Facebook among its members, has a page of “least preferred ad experiences” up on its website. This page calls out pop-ups, autoplaying video ads with sound, interstitial ads with countdowns, and large “sticky” ads as “below the threshold of consumer acceptability.”
