Broadcom introduces low-power WiFi and Bluetooth chips for the Internet of things

The Internet of things -- that nebulous term usually associated with interconnecting everyday objects in a meaningful way -- is in the news again. Yesterday, Broadcom announced that it's launching a couple cost-effective, power-efficient wireless chips geared towards appliances, home automation and wearable devices. The first SoC, BCM4390, incorporates a highly-efficient WiFi radio for embedded use in products such as weight scales, thermostats and security cameras. It fits into the company's range of Wireless Internet Connectivity for Embedded Devices (WICED) chips. The second SoC, BCM20732, features an ultra low-power Bluetooth transceiver and targets devices like heart rate monitors, pedometers anddoor locks. Broadcom's also contributing its Bluetooth software stack to the Android Open Source Project with support for both standard and Bluetooth Smarthardware. Does this mean our long-awaited smart toaster's just around the corner? We sure hope so. Follow the source links below for more info.

NVIDIA announces GeForce GTX 770 for under $400, says it's faster than last year's GTX 680

It probably won't come as a huge surprise, given the GTX 780's appearance last week, but today's launch of the GTX 770 nevertheless brings us a very interesting product. The card is claimed to be about five percent faster than last year's much more expensive flagship, the GTX 680, thanks to faster memory (7Gb/s instead of 6Gb/s), a slightly higher base clock speed (1,046 vs. 1,006MHz) and an equivalent number of CUDA cores (1,536). Seeing as how the the GTX 680 still holds its own with current games, this performance parity strikes us as something of a deal -- assuming independent benchmarks back it up. We're awaiting a confirmed US price, but we'll eat our SATA cables if it's anything other than $399 for a 2GB model (the press release just says "under $400"). UK and European prices match those of theGTX 670 (£329 inc. VAT, 329 euros exc. VAT), and availability begins today. Check out NVIDIA's slide deck for more details, including power consumption and noise, SLI scaling (which looks healthy) and some in-house frame rate comparisons against other products.

Waze 3.7 navigates to Facebook Events, shares directions with others Mobile

It's not hard to navigate to a Facebook Event if there's an address: it's much harder if the organizer simply assumes that we'll know where to go. Thankfully, we can now lean on some collective help through Waze 3.7 for Android and iOS. The update not only populates the destination list with Facebook Events, but fills in the blanks for everyone involved -- enter an address and it will be sent to others on the guest list. It's also easier to be fashionably late with the new app, as Waze members can see when others are likely to show up. Anyone who's ever had to navigate to "that place near the guy with the thing" will likely want to grab the 3.7 upgrade at one of the source links.

Windows 8.1 unveiled: new apps, new features and the return of the Start button

MORE INFO

• Microsoft drops the Blue codename, confirms Windows 8.1 will be a free upgrade available later this year
• Windows Blue screenshot tour
• Leaked Windows 8.1 build points to the Start button's return

How big of an upgrade is Windows 8.1? Put it this way: we just might need to review the OS all over again. Microsoft just unveiled the first major update to Windows 8, and it includes tweaks to nearly every aspect of the operating system: the lock screen, Start menu, Windows Store and onscreen keyboard. As we saw in some leaked screenshots, Microsoft also updated its native apps and added some new ones, including a stopwatch and fresh calculator. In some cases, the update even changes the way you interact with the OS. Yes, that means the Start button is back (sort of). You can now snap more than two windows into place, depending on your screen resolution, and also adjust the width of those columns so that it's not necessarily an 80 / 20 split. Additionally, Microsoft revamped the way built-in search works so that it's now more of a universal search engine, serving up apps, files, settings options and web suggestions.

As you might have guessed, some of these revisions are a response to feedback Microsoft has received in the past seven months. In other cases, like with the new settings menu, they were part of Microsoft's plan all along -- the engineering team just didn't get to them before it was time to ship the first version of Win 8. As we reported earlier, Windows 8.1 will be available as a free update (in preview) starting June 26th, the day Microsoft's Build developer conference kicks off. We'd still encourage you to follow our Build coverage, however, as Microsoft will be making additional announcements then, particularly with regard to its first-party apps. Also, Microsoft is only sharing a handful of screenshots today, so we'll have to wait until June 26th to give you the full visual tour. For now, though, join us after the break as we walk you through all the major (and not-so-major) changes.
