Raspberry Pi 3 has 64-bit CPU, but 32-bit Raspbian OS (for now)

Filed under
Linux

Hacker friendly SBCs like the Raspberry Pi 3 and Odroid-C2 may have 64-bit CPUs, but for now their default Linux OSes remain at 32-bits.

The arrival of the $35, wireless-enabled, Raspberry Pi 3, following a similarly 64-bit, $40 Odroid-C2 SBC a few weeks ago, represent a big speed boost for Linux hacker boards but not a sudden switch to 64-bit ARM computing. The default Linux distributions released by the Raspberry Pi Foundation and Hardkernel’s Odroid project are still 32-bit.

3 open source alternatives to Office 365

It can be hard to get away from working and collaborating on the web. Doing that is incredibly convenient: as long as you have an internet connection, you can easily work and share from just about anywhere, on just about any device. The main problem with most web-based office suites—like Google Drive, Zoho Office, and Office365—is that they're closed source. Your data also exists at the whim of large corporations. I'm sure you've heard numerous stories of, say, Google locking or removing accounts without warning. If that happens to you, you lose what's yours. So what's an open source advocate who wants to work with web applications to do? You turn to an open source alternative, of course. Let's take a look at three of them. Read more

Hackable voice-controlled speaker and IoT controller hits KS

SeedStudio’s hackable, $49 and up “ReSpeaker” speaker system runs OpenWrt on a Mediatek MT7688 and offers voice control over home appliances. The ReSpeaker went live on Kickstarter today and has already reached 95 percent of its $40,000 funding goal with 29 days remaining. The device is billed by SeedStudio as an “open source, modular voice interface that allows us to hack things around us, just using our voices.” While it can be used as an Internet media player or a voice-activated IoT hub — especially when integrated with Seeed’s Wio Link IoT board — it’s designed to be paired with individual devices. For example, the campaign’s video shows the ReSpeaker being tucked inside a teddy bear or toy robot, or attached to plant, enabling voice control and voice synthesis. Yes, the plant actually asks to be watered. Read more
