You may have heard about the latest Raspberry Pi 2 clone: The Orange Pi PC, a device that sells for only $15 yet comes with a quad-core Allwinner H3 and 1 GB RAM. (But don't be fooled - while "open source" is mentioned everywhere on that website, the actual open source situation is still pretty bad).
After my Raspberry Pi started acting up and run very unstable a year ago, this looked like a nice replacement. Thus I decided to order the "Orange Pi PC set 3" including a plastic case and power cable from AliExpress, and will try to get Gentoo running on that device. The manufacturer's Gentoo forum section is all crickets, so I expect to encounter at least some problems.
If you want to see this thing in action, or at least watch me struggling to get Gentoo running, come next weekend (10+11 October 2015) to the Prague Linux Days and visit the Gentoo booth.
For a while, I have been looking for a replacement for my Nexus 4. I have been mostly pleased with it, but not completely. The two things that bothered me most were the lack of dual-SIM and (usable) LTE.
So I ordered a Doogee Valencia2 Y100 Pro at Gearbest when it was announced in June, which seemed to be almost the perfect device for my needs and at 119 USD quite inexpensive too.
Pre-ordering a phone from a Chinese manufacturer without any existing user reports is quite a risk. Occasionally, these phones turn out to be not working well and getting after-sales support or even updates can be difficult. I decided to take the plunge anyway.
Two very good reviews have been published on YouTube in the meantime. You may want to check them out:
My phone arrived two days ago, so here are my initial impressions:
The package contents
The phone came with a plastic hardcover and screen protector attached. In the box there was a charger and USB cable, headphones, a second screen protector and an instruction manual.
Gearbest also included a travel adaptor for the charger. Some assembly required.
Phone specs: Advertisement and reality
The advertised specs of the phone (5" 720p screen, MT6735 64-bit quad-core, 13 MP camera, 2200 mAh battery, etc.) sounded almost too good to be true for that price. Unfortunately, they turned out too good to be true.
The following table shows the advertised specs and the contrast to reality:

Clock frequency was originally advertised as 1.3 GHz, but later changed without notice to 1.0 GHz. The MT6735P has a slower GPU than the MT6735.

2200 mAh battery
1800 mAh battery
There is a sticker on the battery which says 2200 mAh, but when you peel it off it reveals the manufacturer label which says 1800 mAh.
This kind of exaggeration appears to be common for phones in the Chinese domestic market. But some folks still need to learn that when doing business internationally, such trickery just hurts your reputation.
With that out of the way, let's take a closer look at the device:

Camera
Although the rear camera appears to not have a 13 MP sensor (the YouTube reviewers above think it is more like 8 MP), it still manages to reach a quite acceptable picture quality.

Performance
As you can expect, the MT6735P does not particularly shine in benchmarks. The UI however feels snappy and smooth, and web browsing is fine even on complex websites.
Interim conclusion
Despite the exaggerated (you could also say, dishonest) advertisement, I am satisfied with the Doogee Y100 Pro. You can't really expect more for the price.
What next?
Next I will try to get a Gentoo Prefix up on the device. I will post an update then.
Following the news that PC manufacturers have started to use Intel Boot Guard, a technology designed to prevent the installation of modified or custom firmware like coreboot, we now learn that Microsoft may drop the requirement of Secure Boot deactivatability from the Windows 10 Logo guidelines. This collusion between Microsoft and Intel in allowing only vendor signed code during early boot potentially affects all new computers which come with Windows 10 preinstalled.
It means that in a pessimistic scenario, the only thing that stands between Microsoft (or anybody else with access to the infrastructure) being able to disable millions of Linux computers on a whim by blacklisting their bootloader signatures, may be the ability to install user keys in the UEFI key storage. Computer owners would have no other way to defend against this.
It is probably time to familiarize yourself with the procedure to do Secure Boot with your own keys. At least this remains possible, for now.
There has recently been a discussion among developers about the default choice of ffmpeg/libav in Gentoo. Until recently, libav was the default implicitly by being the first dependency of virtual/ffmpeg. Now the choice has been made explicit to libav in the portage profiles, and a news item regarding this was published.
In order to get a data point which might be useful for the discussion, I have created a poll in the forum, where Gentoo users can state their preference about the default:
You are welcome to vote in the poll, and if you wish also state your reasons in a comment. However, as the topic of ffmpeg/libav split has been discussed extensively already, I ask you to not restart that discussion in the forum thread.
