Finally sorted out all the details to get my latest network setup going: by choosing a specific SSID at my house, I end up on a VLAN that routes all internet traffic through the VPN-peered router at my place in Sweden. End result: I can watch the same contents on SVTplay as when I am actually at the place.

I know, I know, tunnel bear works pretty well, but it costs money and this way I can just configure the Chromecast to the same network too, which is really convenient.

If you somehow doubted that the grill briquettes were made from recycled wood: Bonus nail!

We have now released new documentation on how to optimize your app for Chromebooks. We also published what HW features are not supported for developers to better understand what Chromebooks can and can not do.

+Daniel Heitmann​ that's too long of a discussion and I don't know all of the implementation details, but containers can be escaped from, you mention some vulnerabilities yourself in Android and ecosystem, and regardless, more software means greater attack surface just in and of itself. If I want a general purpose computer and that whole paradigm (which Android more or less is), I wouldn't buy a Chromebook. I see Chromebooks as being like the old NetApp filers. Very very good at one thing. Now they're adding SAN capability, virtualization, and on and on. This is about market share etc, not improving Chrome OS. At least, as it looks from here, to someone who likes the paradigm of thick/ netclient computing in the cloud for personal productivity uses.

Nice!
 
Our LAVA farm in +Collabora's Cambridge got more room to grow. Most are Chrome devices and they are plugged to Chamelium boards for CI testing of graphics and multimedia. The will be running jobs submitted by +kernel bot as well.

Yes, there is now a "fake" short fingerprint for my kernel signing key out there on the key servers, and yes, it's not really mine, and yes, we know who did it, and yes, it's revoked, and no, it wasn't just targeted at kernel developers, but at all 24000 keys in the "strong" ring of PGP trust, and yes something like this has been possible for a very long time now so it's not really that much news, and yes, gpg really is horrible to use and almost impossible to use correctly.

See the top comment here for more details:
https://news.ycombinator.com/item?id=12296974

And of course, read the evil32.com site for loads of details.

I guess I should be happy that people are checking the signature of my kernel releases, and emailing me that something is "wrong" on their system, that's nice to see. Too bad their scripts are "wrong" as they pull in all keys with a possible 32bit signature and things go boom.

Short answer, always use "long" keys when using gpg, and never auto-refresh keys from the keyservers.
GPG usage has grown steadily while the tooling that supports it remains stagnant despite staggering hardware advancement. 32bit key ids were reasonable 15 years ago but are obsolete now. Using modern GPUs, we have found collisions for every 32bit key id in the WOT's (Web of Trust) strong set.

4.9 == next LTS kernel.

I need to get my blog back and running (stupid ruby dependencies), so until then, might as well say it here...

Anyone have suggestions for a small and cheap board with two physical Ethernets? I can definitely use something like a CHIP or RPi with USB Ethernet, but it'd be nice to see if there are native alternatives.

SAMA5D3 Xplained seems to be one alternative. One of the Minnows as well. I'm somewhat cost sensitive for this one so cheaper is better.

Thanks, all. When I say price matters, $150-200 is above the range I am looking for. Looks like some ar71xx/72xx is the best bet, but I might just go for a RPi after all.

Nice flames. I find it hard to take good photos of flames.

We are starting to rollout Android apps on the BETA channel for Pixel 2 and R11. Tomorrow we will start with Asus Flip. 

Please report any issues via feedback under Chrome Help.

Thanks
