Android 4.4 KitKat on Galaxy Nexus – ROM, Linaro, and Petition

Google has already released the binaries for Android 4.4 “KitKat” for the Nexus 5, and images are coming for Nexus 4, Nexus 7, and Nexus 10, in the next few weeks. Source code is also available in AOSP (Android Open Source Project). However, even though KitKat has been optimized for older devices, the Galaxy Nexus won’t an official Android 4.4 released because it was released at the end of 2011, which is over the 18 months update window guaranteed by Google. Many people are upset about this decision, and several people have started working on KitKat for Galaxy Nexus. The Linaro team found a solution within minutes by going to the convenience store, and providing KitKat on Galaxy Nexus as shown below. However, usability was not really ideal, so they had some more work to do… In the meantime, Grabak, a developer and member of XDA Forums, provided an alpha […]

$69 Intel Gallileo Development Board Combines x86 Processor and Arduino Compatibility

After UDOO, a Linux development board powered by Freescale i.MX6 ARM Cortex 9 processor and an Atmel SAM3U MCU for Arduino compatibility, here’s another single board computer (SBC) that both runs Linux, and is claimed to be software and hardware compatible with shields designed for Arduino Uno R3: Intel Gallileo. Instead of using two ARM processors, the board is powered by Intel Quark SoC X1000, a 32-bit Pentium class SoC, that handles both Linux and I/Os. Intel Galileo Specifications: SoC – Intel Quark SoC X1000 @ 400MHz with 16 KBytes on-die L1 cache, 512 KBytes of on-die embedded SRAM, single thread, single core, constant speed, ACPI compatible CPU sleep states supported, and integrated Real Time Clock (RTC). Max TDP: 2.2W. System Memory – 256 MByte DRAM Storage – 8 MByte Legacy SPI Flash for bootloader and sketch + 11 KByte EEPROM + optional microSD card (Up to 32GB) Connectors: 10/100 […]

ARM Based Servers and Servers-on-a-Chip (SoCs) at ARM Techcon 2013

ARM Techcon 2013 took place on October 29 – 31, 2013, in Santa Clara, and several companies announced servers, or chips for server based on ARM technology. None of those are for home used, but for now ARM based servers target enterprise and cloud data. Yet end users may them indirectly when they access social networks such as Facebook, or other online services such as Paypal. Calxeda ECX-2000 SoC After their ECX-1000 quad core Cortex A9 Server-on-chip, Calxeda has announced ECX-2000 SoC featuring four Cortex A15 cores. The new SoC provides about twice the performance, 3 times the memory bandwidth, and 4 times the memory capacity (up to 16GB RAM) of the earlier chip. One of the key advantage of Cortex A15 over Cortex A9 is hardware virtualization that allows support for KVM and Xen hypervisors. ECX-2000 is supported in Canonical Ubuntu Linux 13.10 and can run Havana Openstack. Other […]

Motorola’s Project Ara Open Source Hardware Plaform for Modular Smartphones

A few months ago, I posted a video about “The Smarter Phone“, a concept smartphone that was supposed to be serviceable and upgradeable just like PCs used to be, in order to reduce e-waste among other things. Based on comments here and on Reddit, most people did not really believe the concept was feasible, practical or cost effective, myself included. Fast forward to September, a video about another concept modular smartphone called Phonebloks went viral with over 17 million views. The overall idea is basically the same, but this time there seems to be at least a mockup. Phonebloks features a base where you can attach blocks such as the display, a wifi module, processor module, bluetooth module and so on. It turns out Motorola’s Advanced Technology and Projects group has been working on something similar for a year with Project Ara, and they recently partnered with Phonebloks’ guys, since […]

Linux Kernel 3.12 Released

Linus Torvalds has announced the release of Linux Kernel 3.12: I was vacillating whether to do an rc8 or just cut the final 3.12, but since the biggest reason to *not* do a final release was not so much the state of the code, as simply the fact that I’ll be traveling with very bad internet connection next week, I didn’t really want to delay the release. Sure, we had a number of driver reverts, and there was an annoying auto-NUMA memory corruption fix series, but none of it was really worth delaying 3.12 for. But the fact that I’m going to be (effectively) off-line next week means that I’m *not* opening the merge window for 3.13 yet – since I won’t have the bandwidth to really do merges anyway. That doesn’t mean that you can’t send me pull request for the merge window early, of course – maintainers can […]

$91 IPPLI Mars i8 is a Cylinder Shaped STB Based on Rockchip RK3188

Most of set-top boxes come with a casing with a rectangular shape. But some designs are more original: spaceship-like, spherical, or even in the shape of a pyramid. We’ve now got another option with IPPLI Mars i8, a media player based on Rockchip RK3188, that comes with a cylindrical enclosure. Here are the technical specifications of the device: SoC – Rockchip RK3188 quad core Cortex A9 @ 1.6 GHz + Mali-400MP4 System Memory – 2GB DDR3 Storage – 8GB NAND Flash + microSD slot (Up to 32GB) Connectivity: Wi-Fi 802.11 b/g/n with external Wi-Fi antenna. Bluetooth Bluetooth 2.1 + EDR 10/100M Ethernet Video Output – HDMI v1.4 up to 1080p Audio Output – HDMI, optical audio, and 3.5mm jack Camera – 2.0MP with microphone USB – 2 x USB 2.0 port, 1 x Mini USB (OTG) Dimensions – 8.5 cm x 8.5 cm x 13.0 cm Weight – 252 g […]

One2Touch Softpad C1 and S1 are NFC Keyboards for Android Devices

It’s pretty easy to find Bluetooth keyboards if you want to a keyboard to type more easily and faster on your phone. They have two small inconveniences however: they need to be paired, and need to be recharged. The first one is not really a problem, but the second can be. If your phone supports NFC, you can now get One2Touch Softpad C1 or S2 wireless keyboard using NFC technology. These do not require pairing, nor charging (but uses CR2025 batteries). Softpad S1 is similar to C1, expect there’s space in the middle of the keyboard to insert your phone. S1 has recently been (quickly) reviewed by Android Central. To make the keyboard work with your Android smartphone, you’ll need to download the drivers from Google Play, and you’re ready to go. You can watch the video below for some of the use cases with Softpad C1. I could not […]
