Google Maps 5.0 for Android

By

Google Maps 5 for Android comes with two features that make Google's mapping software a lot more useful. Google now uses vector graphics instead of map tiles and it caches some of your most frequently used maps so that they are available offline.

Vector-based maps allowed Google to add a lot of cool gestures:

 

Tilting: Drag down with two fingers to tilt the map. Tilt while zoomed in on one of the 100+ cities around the world with 3D buildings to see a skyline spring to life.


Rotating: Twist with two fingers to rotate the map. After tilting to see 3D buildings, rotate around them to gain a new perspective from any direction.

Smooth zooming: Slide two fingers together or apart, and see the map and labels continuously scale to any zoom level, stopping when your fingers stop.

Compass mode: Center the map on your location, and then tap the compass button in the top right corner. The map will flip into 3D mode and start rotating to match your perspective, while still keeping all the labels upright and readable.

The new 3D view makes maps more intuitive and easier to use, but that's not all. Since Google no longer has to download map images from its servers and vector-based maps require 100 times less data for all zoom levels, it's feasible to cache data. "Rather than having a static set of maps when installed, Maps will automatically start caching the areas you visit the most when your device is plugged in and connected to WiFi (e.g., the nightly charge)." You can't manually control caching, but it's an important first step toward an offline Google Maps.

Google also promises to add offline rerouting to Google Maps Navigation. "You'll still need a connection to start a route, but if you miss a turn along the way, we'll quickly get you back on track, even if you don't have an Internet connection."

Google Maps 5 for Android uses about 70% less data than the previous version, so it loads maps much faster. The new features require Android 2.0+, but not all devices support them. The list of devices that support all multi-touch gestures includes: Samsung Nexus S, Samsung Galaxy S, HTC G2, HTC Incredible, HTC Evo 4G and Motorola Droid/Droid 2/Droid X, while HTC Nexus One, HTC Desire, Sony Ericsson X10 and LG Ally don't support rotating gestures.

Encourage Employees to Learn by Sharing Your Own Growth

By
As a manager, it’s your job to make sure everyone on your team keeps learning. But beyond encouraging people to take classes and go to conferences, how do you do it? A good starting point is to talk about your own development. When managers open up about their personal areas for improvement, it becomes more acceptable for everyone else to do the same. Ask yourself these questions, and share the answers with your team: “What areas do I need to grow the most in? What insights have I found helpful in accomplishing these goals?” And when you come back from a workshop or training, don’t resort to the typical “It was interesting” summary — be specific. For example, you might say, “I thought I was a good listener, but now I can see that this is a growth area for me. The training showed me new ways to interact with others, and although they aren’t necessarily comfortable for me, I’m going to try them out.” Adapted from " Make Sure Everyone on Your Team Sees Learning as Part of Their Job ,...

The Solution to a Tough Problem Isn’t to Overthink It

By
We all like to consider ourselves smart, but raw intelligence isn’t everything. When we get stuck on a problem, sometimes it’s because we’re overthinking it. Pay attention to when focused thinking isn’t getting you anywhere; perhaps it has turned into obsessing over the same answers or approaches. Consider whether experimenting with a new strategy or talking ideas through with others might be more likely to result in success. Take breaks to let your brain relax and get unstuck. Expand your range of skills for reaching insights and coming up with new ideas; don’t be someone who sees every problem as a nail because your only tool is a hammer. And when you do find yourself ruminating, disrupt it by doing a few minutes of an absorbing activity, such as a puzzle. This can be a surprisingly effective way to break your brain out of a rut.
