I’ve been using the device as my main smartphone for over a week, and I’m now ready to write a full review for the phone. General Impressions At first the material and color used on the back cover feels a little strange, but I quickly got used it, and the build quality seems pretty good, and the phone is very light. I must have made one or two calls during the week, and I mainly use my smartphone to check emails, run social network apps, browse the web, play some casual games like Candy Crush Saga, watch YouTube videos, and make Skype calls, and for these tasks I could not really fault […]

Allwinner CedarX Media Codec Library GPL/LGPL Compliance Update

Last month, I wrote about potential open source licenses and VP6 copyright infringement by Allwinner with their CedarX media codec library, and then since there’s been a few developments. First, Allwinner sent me an email saying they’ve now updated Cedarx library and referring my previous article. Here’s an extract: Here, I have some update of the Allwinner’s open-source status. We have done a lot of discussion with the developers from the linux-sunxi communication about the software license of CedarX. For each question or requirement asked by the developers, Allwinner has identify and try to give the best solution. Now, we believe Allwinner’s CedarX license is fully compliant and resolves concerns from the community.

How to Install Ubuntu 14.04 on Acer Aspire E5 Laptop

I’ve been owning an Acer Aspire One D255E netbook with a 10″ display, an Intel Atom N455 processor and 1GB RAM that served me well during my travels, but as I’ve become older and less patient, I felt I needed to upgrade it. I planned to spend around 10,000 Baht (~$300), wanted a 14″ display, one of the low power CPU such as Intel Bay Trail-M or AMD Mullins / Beema processors, at least 500GB storage, 4GB RAM, and the ability to install Ubuntu. Finally, after going through several products at my local shop, I had to chose between Acer Aspire E5-411-P3CL with a 7.5W TDP Intel Atom N3540 and Acer Aspire E5-421G-45L0 with a 15W TDP AMD A4-6210 processor that both sell for 11,900 Baht ($365). Despite my preference for processor with lower TDP, I still went with the AMD system, since the performance is a little better, the […]

Asus C201 Chromebook to be Powered by Rockchip RK3288 Processor

If you’ve been following this blog, you should know that Rockchip is working with Google on Chrome OS, so it was just a matter of time before a Rockchip powered Chromebook or Chromebox sees the light of the day. The first Rockchip RK3288 chromebook might end up being Asus C201 Chromebook with apparently a custom version of the Cortex A17 processor dubbed Rk3288-C, as OMG Chrome found out in Troxell’s 2015 brochure for K-12 education. So far we only know a few details about the specifications: SoC – Rockchip RK3288-C quad core Cortex A17 processor @ up to 1.8GHz System Memory – 2 to 4 GB DDR3 Storage – 16GB eMMC Display – 11.6″ display with 1366×768 resolution Webcam – VGA resolution The exact model name should be C201PA. Rockchip RK3288 should provide performance quite similar, and in some cases even better, to Intel Atom Z3735F, except possible when it comes […]
