Inforce Computing Introduces 6301 SoM and Devkit Powered by Snapdragon 410E SoC with Long Term Availability

Qualcomm launched Snapdragon 410E and 600E processors for the embedded market at the end of September, meaning the processors were easy to source by any company, not matter how small they are, and the company would now offer long term availability often required for embedded systems. Inforce Computing is now leveraging the new Snapdragon 410E processor with their Inforce 6301 micro SoM, and corresponding development kit. Inforce 6301 micro SoM specifications: SoC – Qualcomm Snapdragon 410E (APQ8016 SoC) quad core ARM Cortex A53 processor @ 1.2GHz, Adreno 306 GPU, and Hexagon DSP @ 700MHz Memory – 1GB LPDDR3 @ 533MHz (Option: 2GB) Storage – 8GB eMMC v4.5 flash (Option up to 64GB) NAND, 1x micro SD card interface with support up to HS200 Connectivity – Bluetooth 4.1 LE, Wi-Fi dual stream 802.11 b/g/n @ 2.4GHz (WC3620), on-board GPS/GNSS/BeiDou/Galileo (WGR7640) Video – H.264/263 playback and capture @1080p; H.265 playback @720p; Interfaces […]

Giveaway Week – Star Cloud PCG02U Ubuntu TV Stick

The fourth device for this giveaway week will be MeLE Star Cloud PCG02U TV stick powered by Intel Atom Z3735F quad core processor, but instead of running Windows 10, the device is sold with Ubuntu 14.04, which I upgraded to Ubuntu 16.04. I found out that the device was running pretty well (minus Bluetooth support) in my PCG02U review, and for the price at the time ($70) it was really a good deal. The device has even become the best selling devices on MeLE Aliexpress store, outselling all other Windows devices. However, MeLE ethics are questionable since they used Ian Morrison (Linuxium)’s image in their devices without giving any credits. The package will come with all accessories above, minus the “Caution Hot” sticker which must have gone to sticker heaven…. Simply leave a comment below to enter the draw. Other rules are as follows: Only one entry per contest. I […]

UP Squared Apollo Lake Development Board Comes with Up to 8GB RAM, 128 GB Storage for 89 Euros and Up (Crowdfunding)

AAEON Introduced a Intel Atom X5 based Raspberry Pi-like development board named “UP Board” last year that sold for as low as 89 Euros via a Kickstarter campaign. The company is now back with the first Apollo Lake development board for makers I’ve seen so far, powered by either a dual core Celeron N3350 or a quad core Pentium N4200 processor, featuring an Altera MAX 10 FPGA, and called UP2 (“UP Squared”). There are six variants of UP Squared board sharing most of the same technical specifications: SoC Intel Celeron N3350 dual core “Apollo Lake” processor @ 1.1 GHz / 2.4 GHz with 12 EU Intel HD graphics 500 @ 200 MHz / 650 MHz (6W TDP) Intel Pentium N4200 quad core “Apollo Lake” processor @ 1.1 GHz / 2.5 GHz with 18 EU Intel HD graphics 505 @ 200 MHz / 750 MHz (6W TDP) FPGA – Altera Max […]

Quirky Linux 8.1 Lightweight Linux Desktop Distribution Released for Raspberry Pi 2 and Pi 3

Barry Kauler, the creator of Puppy Linux, may have retired from maintaining Puppy Linux a few years ago, but he appears to be still active, as he’s just released Quirky Linux 8.1 for Raspberry Pi 2 and Pi 3 boards, a lightweight Linux desktop distribution based on Ubuntu Xenial Xerus 16.04, and including LibreOffice & Inkscape to have the same out of the box experience as Raspbian, but with a 360 MB download size instead of 1.3 GB for Raspbian. A build for ODROID-XU4 development board should also be coming soon. The image has been designed for 8GB micro SD card, and needs to extracted and dumped onto the card with the usual Win32DiskImager or dd tools. There are three mirrors for quirky-pi2-sd-8gb-xerus-8.1.img.xz firmware: iBiblio.org, nluug.nl, and archive.org. You can read the full release notes if you want more details. In case you don’t have a spare micro SD card, […]

Canonical Livepatch Service Automatically Updates Ubuntu 16.04 LTS (and later) with the Latest Kernel without Rebooting

Installing or upgrading packages in Linux distributions does not normally require rebooting your system, except for the Linux kernel and drivers. But since Linux 4.0 kernel, Live Kernel patching is possible, meaning Linux kernel updates can be performed without having to reboot your server or computer. Canonical is now taking advantage of this new feature with their Livepatch Service available for Ubuntu 16.04 LTS and greater. If you want to enable it on your machine, you’ll have to authenticate to Livepatch portal to get a key / token for the service as shown in the screenshot above. Now you can install the service:

sudo snap install canonical-livepatch

1	sudo snap install canonical-livepatch

and enable it with your token:

sudo canonical-livepatch enable [your-token]
Successfully enabled device. Using machine-token: [your-token]

1 2	sudo canonical-livepatch enable [your-token] Successfully enabled device. Using machine-token: [your-token]

That’s it. Your can check Livepatch service status with the command:

canonical-livepatch status --verbose
client-version: "5"
machine-id: [your-machine-id]
machine-token: [your-machine-token]
architecture: x86_64
cpu-model: AMD FX(tm)-8350 Eight-Core Processor
last-check: 2016-10-25T19:35:55.009247615+07:00
boot-time: 2016-10-25T09:00:09+07:00
uptime: 10h52m7s
status:
- kernel: 4.4.0-45.66-generic
  running: true
  livepatch:
    state: nothing-to-apply
    version: ""
    fixes: ""

canonical-livepatch status --verbose

client-version: "5"

machine-id: [your-machine-id]

machine-token: [your-machine-token]

architecture: x86_64

cpu-model: AMD FX(tm)-8350 Eight-Core Processor

last-check: 2016-10-25T19:35:55.009247615+07:00

boot-time: 2016-10-25T09:00:09+07:00

uptime: 10h52m7s

status:

- kernel: 4.4.0-45.66-generic

running: true

livepatch:

state: nothing-to-apply

version: ""

fixes: ""

In my case, an update was not necessary, but if there’s one you should see something like:

livepatch:
    state: applied
    version: "12.2"
    fixes: '* CVE-2012-6828'

livepatch:

state: applied

version: "12.2"

fixes: '* CVE-2012-6828'

That way you can make sure your system always […]

Ubuntu 16.10 Images Released for Intel Bay Trail and Cherry Trail Processors

Canonical formally released Ubuntu 16.10 “Yakkety Yak” yesterday with a developer preview of Unity 8 including desktop, tablet and phone UX convergence, Hybrid cloud operations with Juju 2.0, Snapd 2.16 with more than 500 snaps, etc.. Ian Morrison (Linuxium) wasted no time, and put together a Ubuntu 16.10 image working on platforms powered by Intel Bay Trail and Cherry Trail processor with modifications to have audio, WiFi and Bluetooth working. If you want to try Ubuntu 16.04 on your device you can download ubuntu-16.10-desktop-linuxium.iso and prepare a bootable USB flash the usual way with rufus, or other utilities. If you’d like to try an alternative Ubuntu flavor such as Lubuntu, Xubuntu, Kubuntu, Ubuntu GNOME, or Ubuntu MATE, Linuxium got you served too, and you’ll find the images on his blog. Unity 7 is still running by default in Ubuntu 16.04, but if you are curious about Unity 8 convergence desktop/tablet/phone user […]

How to check HTTP Header and Connection Stats from the Command Line

A few days ago, I discussed with somebody whether a file was cached by Cloudflare or not, and this involved getting the HTTP header, and checking for CF-RAY field to see if data is going through one of Cloudflare data centers. This can be done with curl:

curl -svo /dev/null http://www.cnx-software.com
* Rebuilt URL to: http://www.cnx-software.com/
*   Trying 104.28.19.95...
* Connected to www.cnx-software.com (104.28.19.95) port 80 (#0)

In the command above, -s stands for silent so that curl does not show the progress meter, -v stands for verbose to show the header, and -o /dev/null is used to discard the packet load. You can also use -I option (fetch the HTTP-header only) with curl, which – if all you need is the HTTP header – provides a cleaner output:

curl -I http://www.cnx-software.com

I also came across httpstat Python script recently via n0where, doing much of the same thing, except it also adds transfer statistics. It can be installed by downloading httpstat.py, or better using pip:

sudo pip install httpstat
