Well, let's see, we've only been saying this is possible for 16 years now. Nobody cared.

If you don't need a high end laptop with tons of ram and disk, just go get a chromebook. If you don't like chromeos load +John Lewis firmware and if you really still want windows talk to +CoolStar Organization . But if you buy a UEFI-based laptop, just save a step and assume you're owned by embedded code that can't be erased. Because you probably are.
A recently uncovered feature – which had been swept under the rug – allowed new Lenovo laptops to use new Windows features to install the company's software and tools even if ...

I got a couple of Lenovo E540 and installed Ubuntu before even installing/booting Windows. I guess I am not able to install Windoze anymore (what a pity) and hopefully the Ubuntu installer wiped all the crap.

OK, so in case you use this OK Google nonsense on nexus 5, there's a great opportunity to make yourself look like an a**, twice.

Use 'OK Google, turn on flashlight' to turn on the backside LED. Now use the pulldown menu and notice that the LED icon has disappeared and you have no way to turn the backlight off. You can either use 'OK Google turn off flashlight' or reboot the phone.

Extra points obtained for finding this bug while ranting about siri vs. OK Google with an apple guy at a pub.

I tried to do this, but it appears the Mic on my N5 really has died completely now :-(

At times, I'm really wondering whether there is any QA involved with Android at all. Grave usability flub of the day is this:

- Neither my handsfree not my moto360 connect to my Android phone since this morning or so.
-> rebooting moto360 doesn't help
-> let's try turning Bluetooth on the nexus 5 off and on ...

Yeah, I can't turn Bluetooth off on the nexus5 anymore after it was on for a few days. Excellent. Rebooting the nexus5 helps, but this is total QA disaster. How hard could it be to notice such a bug if there was any QA at all?

Interesting, I'll have to fight similar spi muxing soon.
This patch contains the core functionality for a multiplexer on an SPI bus. This can be useful if a board requires more SPI devices, and thus more chip selects, than the SPI controller on the processor has available. The mux device is added in the device tree as a child node of the SPI master.

I pushed the MX6 IPU CSI patches based on those from +Philipp Zabel but rebased to Linux 4.1.4 to our gitlab [1] and explained how to use them [2].

http://lists.freedesktop.org/archives/systemd-devel/2012-November/007375.html this is really sad and I hit it today. I cannot use sfdisk anymore to reliably partition a disk from a script thanks to udev interferring.

So, I decided to go with Lennart's advice and switch to parted. Big surprise, parted does not allow me to configure basic stuff like partition ID and doesn't support resizing of a partition, thus, it is useless.

What is the correct way to reliably partition a drive from script today, now that the tools that used to work for decades are obsolete ?

Anyone know if this also affects eudev?

Thanks to +Philipp Zabel , who wrote initial i.MX6 CSI support for Linux 3.17-rc , I can now kind-of use the OV5642 on the SabreLite. It took some additional plumbing, but I can finally get some picture from the thing.
