Kinks worked out of video streaming device

The new model of Google's Chromecast digital streaming device isn't a whole lot different from its predecessor, but it's impressive how good of a device it has become.

When it launched, the device seemed to be more of a work in progress rather than a finished product. It only worked with a handful of apps, there was no way to beam pictures or movies stored on users' phones to their TVs and video streamed to it could be choppy.

By now, though, Google and its legion of software developers have addressed many of these problems. The new version can interact through an Android or Apple phone or tablet with thousands of apps. Among them are many of the most popular streaming media services, including Netflix, Spotify and HBO Now. Additionally, you'll find apps that will let you play games with your phone as the controller.

Although the new Chromecast still doesn't come with a remote control, Google does have a Chromecast app for both Android and iOS devices that makes it easier to control and use the device.

The device isn't perfect, of course. Unlike the latest — and much more expensive — streaming media boxes from Roku, Amazon and Nvidia, the new Chromecast doesn't support 4K, the new standard for ultrahigh resolution video that's becoming more common among the latest televisions. The Chromecast also works better with Android devices than with iPhones or iPads.

App can identify trees

The main part of Leafsnap is a huge index of tree species found in North America; each entry has its own small leaf graphic. You can view the list alphabetically by common or scientific name or search to find a particular reference. A page of text tells you about the tree, including its habitat, life span and where it is usually found.

Using this list means you have to know a bit about trees to start with. But the app also has a section where you can snap a photo of a leaf on a white background and it will try to automatically identify the species for you. The accuracy can be hit-or-miss, but since the app is free on iOS, it's worth trying.
