I must, sadly, withdraw my endorsement of yubikey 4 devices (and perhaps all newer yubikeys), as apparently Yubico has replaced all open-source components that made yubikey NEOs so awesome with proprietary closed-source code in Yubikey 4s:

If you are already using yubikeys, there is no need to replace them, as this will not result in a net improvement in security -- especially if you are only using them for one-time password functionality (press the button to emit a 6-digit code).

On 9 July 2015, the European Parliament might destroy photography. The Freedom of taking photos in public places is under attack. Until now, in most countries in Europe you were safe to take and publish photographs that are taken from public ground – This is called Freedom of Panorama. When you were on vacation, you could take a photo from the London Eye and share it with your friends on Facebook*. If someone wanted to pay you for using this p...

Ende für DD-WRT & Co.?
 ·  Translate
Freier Systemsoftware auf Geräten mit Funk-Funktion könnte es bald an den Kragen gehen: In der EU tritt ein Verbot im Juni 2016 in Kraft, in Nordamerika soll es alsbald beschlossen werden. Leidtragende dürften Hersteller wie DD-WRT sein.

Schlimm wenn es wirklich so kommen wird. Dann werden die Preise steigen und vor allen Dingen ältere System werden offen wie ein Scheunentor wenn es dann keine Updates vom Gerätehersteller mehr gibt.
