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 […]

$480 Hewlett-Packard SlateBook x2 Is an Android Tablet/Notebook Hybrid Powered by Nvidia Tegra 4

Although not really designed for this purpose, Android has been used in devices such as set-top boxes, netbooks and mini PCs for a while, mainly in Chinese products, but recently Hewlett-Packard has announced an All-in-One PC running Android 4.2. The company is persevering its Android push on “legacy” computing devices with a 10.1″ Laptop / Tablet hybrid powered by Nvidia Tegra 4, and running Android 4.2, called SlateBook x2 (Full name: SlateBook x2 10-h010nr).

HDMI to VGA Adapters Now Cost About $10

I remember when the Raspberry Pi first got out, many people wanted to connected it to a VGA display, and at the time, a cheap HDMI to VGA adapter would have cost $30, about the same price of the low-cost ARM11 board. Since then things have changed since it’s possible to find HDMI to VGA adapters for less than $10, and even less than $7 on Aliexpress. The one linked and pictured above has an HDMI male connector and a VGA female connector, and the following  features listed in buyincoins: Support 1080p and 720p. Built-in chipset. No external power required, power supply from HDMI signal. Don’t support audio output. Can use for connecting devices with VGA port to HDTV. HDMI – standard type A port male. VGA – VGA video port, female. The title seems to imply it’s an HDMI to VGA adapter, but the description tells you it’s for […]

JW-11 Android or Linux Media Player Supports Internal 2.5″ Hard Drive

If you’re not simply watching movie streamed from the Internet, one way to store your media files is in a NAS, and another way is to store directly into your media player with an Hard drive. Unless you run a SAMBA or NFS server within your media player, you may lose the ability to access your files from several devices, but by playing directly from the hard drive, you are sure any video will be played smoothly. There are few low cost set-top box that support SATA, and the ones that do, such as Mele A1000 and its successors, simply offer an external SATA connector leaving your hard drive without protection from dust. I’ve just noticed there’s a low cost solution with an internal HDD enclosure thanks to an Android set-top box powered by Amlogic AML8726-M3 called either JW-11 or Slav, and maybe some other names I’ve missed. Here are […]

Wandboard Dual Benchmarks, Serial Console Fun, and Distributions List

Since last time I tried Android and Ubuntu on the Wandboard, a few things happened. I’m not talking about Wandboard Quad announcement, but instead I received a Class 10 SD card, which makes the system so much responsive, and a RS232 to USB adapter so that I can access the serial console. So today, I’ll publish some benchmark results on Wandboard Dual since none appear to be available, and play a little with the serial console. A few things also happened on the operating systems side with more distributions now available for the board. Prerequisites I ran benchmark in Android, so I installed the latest Android 4.1.2 image (11th of April 2012) to my new SD card (ADATA 16 GB Class 10), and contrary to my poor experience on a 4GB Class 4 micro SD, everything was very fluid. I’ve also installed Google Play in order to install the applications. […]

Adding Wi-Fi to Emcraft Systems K70 SoM

Emcraft Systems K70 SoM is a system-on-module powered by Freescale K70 Cortex M4 micro-controller with enough RAM (64 MB) to comfortably run uClinux. They used to charge $99 for their uCLinux BSP, but it’s now free of charge, and the company also provides full hardware and software documentation, including a getting started guide, schematics and BoM for the baseboard, application notes and more… Many of their clients want to use Wi-Fi with K70 SoM, and it can easily be done by using Wi-Fi USB dongles based on Ralink RT5370 chipset such as D-Link DWA-140 (H/W rev B3) or Comfast CF-WU815N. Emcraft has provided detailed instructions to do so with K70 SoM, their latest baseboard (SOM-BSB-EXT) and a demo image based on their uClinux BSP. I’ll summarize the instructions to use K70 SoM as a Wi-Fi access point below. Connect the baseboard and K70 SoM with an Ethernet cable, a mini […]

PowerUSB Computer Controlled Power Strips Review

PowerUSB power strips are four outlets power strips designed to help users save power by better understanding their devices power consumption, and automatizing tasks such as power on/off using timers, printer on/off controls, and more. One outlet is always on (for the main computer) and the 3 remaining outlets can be controlled via USB and the control software installed in a Linux, Mac or Windows x86 machine. The three of the four outlets are controlled through the software.  Those power strips should allow lower electricity bills, and cover the cost of the strips ($69 to $129) within a few months. There are 4 models: PowerUSB Basic – $69.99 – The simplest model. You can control the 3 programmable outlets with on/off timers and keyboard shortcuts. PowerUSB Digital IO – $109.99 – This version adds 5 digital input/output lines for instrumentation and automation. The current model has 3 inputs and 2 […]
