FOSDEM 2015 Schedule – January 31 – February 1 2015

FOSDEM (Free and Open Source Software Developers’ European Meeting) takes place every year during the first week-end of February. This year the developer-oriented event expects to bring over 5000 geeks to share ideas and collaborate on open source projects. Contrary to most other events, it’s free to attend, and you don’t even need to register, just show up. FOSDEM 2015 will take place on January 31- February 1 in Brussels. There will be 551 sessions divided into 5 keynotes, 40 lightning talks, 6 certification exams, and with the bulk being developer rooms and main tracks,  divided into 7 main tracks this year: Languages, Performance, Time, Typesetting, Hardware, Security and Miscellaneous. I’m not going to attend, but it’s still interested to see what will be talked about, and I’ve concocted my own little virtual program out of the main tracks and developers’ rooms. There’s a few minutes overlap between some talks […]

MeLE PCG03 Windows 8.1 Fanless mini PC Unboxing

MeLE is PCG03 now is now available with 2GB RAM, and 32GB eMMC, and with a properly licensed “Windows 8.1 with Bing NTE”, but no Android for $149 on Ebay, or Aliexpress, and it should eventually show up on MeLE Amazon store. The company sent me a sample for review, so I’ll start by listing the updated specifications, and taking pictures today, before running benchmarks, trying out Kodi, and trying Ubuntu in other posts. MeLE PCG03 Specifications The look of the device and available ports have slightly changed since the first prototype was revealed last year. SoC – Intel Atom Z3735F “Bay Trail” quad core processor @ 1.33 GHz (Bust freq: 1.83 GHz) with Intel HD graphics System Memory – […]

4K Output and Video Playback Capability Tested on 6 ARM based mini PCs and Boards

Since I’ve now got a 4K TV, I’ve decided to test 4K support for six different platforms based on Rockchip, Allwinner, Amlogic, Realtek, HiSilicon, and Mstar processors. For all these platforms I’ll report HDMI 4K output options, user interface resolution, and take close up pictures of the screen while displaying a 4K 1×1 grid picture and video with the image players, and video players such as MX Player or XBMC depending which are available in the firmware. Test Setup and Procedure I’m using LG 42UB820T 42″ UltraHD television with an HDMI cable connected to HDMI 1 port of the TV. Please note that my TV only support 8-bit color depth / YCbCr 4:2:0 which may cause compatibility issues with some boxes, at least the ones based on RK3288 processor, for 2160p 50Hz or 60Hz mode. I’ll take close-up pictures of the screen with a Canon PowerShot A2300HD camera by holding […]

LG 42UB820T 4K UHD TV Review

After several people often asked me about audio pass-through, and 4K video support on mini PCs, with some suggesting adding a donation button to my website, I decided to start a crowdfunding campaign to raise funds for an AV Receiver and a 4K TV by asking for donations and selling some samples I used for review. Thanks to the great help of my readers, I managed to get enough money to buy LG 42UB820T on Lazada for 19,610 Baht including shipping (~$600) via 10% coupon I got in a newsletter, as well Onkyo TX-NR636 7.2 channel receiver in a local shop in Chiang Mai (Sahapanich). I’m still waiting for the speakers, so I’ll start by reviewing the TV. This model is sold as 42UB820V in Europe, and 42UB8200 in Hong Kong and probably other markets. I spent a lot of time studying about 4K TV and AV receiver features, and […]

Snappy Ubuntu Core is an IoT Linux Distribution for ARM and x86

Canonical has announced a version of Ubuntu specifically designed for IoT devices running Linux, with a low hardware requirements, and a new package manager called snappy, replacing apt-get for this version of Ubuntu, which provides simpler, faster, and more reliable updates, stronger security, and allows roll-backs in case something goes wrong. Easy firmware updates are something missing in most connected device, which means they are more vulnerable to potential hackers, but with snappy security updates should be able to make it regularly, so that if something like heartbleed occurs again, you know your router, home automation gateway, connected washing machine, or robot will be soon patched automatically. Let’s go through the hardware requirements first: Processor – 600 MHz processor (ARMv7 or greater, or x86) System Memory – 128 MB RAM or greater (The system itself uses 40 MB RAM) Storage – 4GB flash / storage for factory reset and system […]

Mini Review of VidOn Box Android Media Player

Vidon Box is an Allwinner A31s based TV box made by Vidon.me, a Diamond sponsor for Kodi entertainment center. I’ve already listed specs, subscriber services, and uploaded pictures in the unboxing post, so it’s time for a review. Since Allwinner A31s has been around for a while, I’ve decided to write a shorter review. First Boot, Setup, and First Impressions Since the box provides some services with a subscription, with a free 1-year top-up card included, you’ll probably want to register an account on Vidon.me first, as it’s needed to activate all services in the box as shown on the back of the top-up card. After the optional Subscription is $14.99 per year, and it’s only needed if you need features like Blu-ray navigation, or audio pass-through. The simple remote included does the job if you only use the box for settings and XBMC, but otherwise you’ll need an air […]

Downloading Files on Baidu, or via HTTP, Bittorrent or Metalink in Linux with BaiduExporter, Aria2 and YAAW

Most firmware files distributed by the manufacturers are uploaded to Baidu, but I’ve found the service not to be always reliable, especially for larger files. In Windows, people are recommended to use Baidu software (BaiduYunGuanjia), but there’s not such tool in Linux, so instead I investigate for command lines tools to download files from Baidu, and this lead me to two interesting tools called Aria2, a “lightweight multi-protocol & multi-source command-line download utility. It supports HTTP/HTTPS, FTP, BitTorrent and Metalink”, and YAAW “Yet Another Aria2 Web Frontend” with allow to start and monitor download locally or remotely. But let’s start with the first tool I found: pan-baidu-download, a Python script to download files from Baidu. To install it:

We also need to install some dependencies (assuming python 2.7.x is already installed):

and then you can start downloading files as follows:

But after posting a bug about password-protected […]

How to Upgrade Firmware in HiSilicon Hi3798M TV Boxes

HiSilicon based Android TV boxes are not that popular, at least outside of China, but I’ve got one with BFS 4KH featuring HiSilicon Hi3798M processor, and since we could not fix AC3 audio decoding after a factory reset in the firmware I have, the company provided me with a new firmware, and I’ll document the procedure I followed below. Download the firmware, the file should be update.zip. For BFS 4KH, I could get it @ http://pan.baidu.com/s/1kTrCcMr (password: xpef). It includes YouTube and Google Play, but not the Rainbow launcher, nor XBMC, but these can be side-loaded. Now copy update.zip on the root of a USB flash drive formatted with FAT32, and at least 1GB free storage. Connect the USB flash to the USB 2.0 port of the device, as the USB 3.0 port can’t be used for firmware upgrade. In the current firmware, go to Settings->System->Local Update, and select the […]
