If you can agree to contractual terms by clicking through some agreement, you can agree to "waive" your DNT setting
In the US and UK, the requirement for a contract to be enforceable in court is that the side wishing to enforce it must demonstrate that a meeting of minds has occurred. It's far from a binary decision. Some things, such as witnessed signatures at the bottom with each page initialed, have large amounts of case law backing them up, so you need a very strong argument if you want to discount them. For click-through licenses, there's a lot less case law and everything on the opposing side helps. If you can demonstrate that you have actively opted out of tracking and then been presented with a click-through license that, buried somewhere in legalese, there is a permission to track, it's easier to argue that the contract is invalid.
Either way, I am not sure what court is going to protect you from malicious actors that would not follow DNT.
The various European data protection offices would be a good bet.
We should be working on stopping the ability to track, not about making statements of intent for possible future litigation in a court of law.
Making it impossible to track means making clients indistinguishable, which is very hard. Making tracking without consent illegal is much easier, because the companies that you really worry about doing the tracking are the ones with large and expensive data centres where they can process the data, and these are nice big targets.
No. The nVidia drivers share around 90% of their code between all platforms (Windows, Linux, FreeBSD, Solaris) and the open source ones all use the Gallium framework, which is designed for portability from the ground up.
Modern GPU drivers require a set of services from the kernel, mostly related to memory management. They need to be able to get access to the device's I/O range in the physical address map and they need the kernel to grant access to texture memory in both main memory and the device. That's about all that they need from the kernel.
At the top, they need a state tracker that manages 3D API state (which is fairly minimal on modern APIs, as they aim to be stateless for performance reasons) and that translates the shader programs into some intermediate representation.
The majority of the device-specific driver code lives between these two layers, which are usually handled by abstraction layers so that they can be plugged into different APIs. You use the same Gallium driver with an OpenGL 2, OpenGL 3, OpenVG or Direct3D state tracker.
The only person who should be curating personal photos in Facebook is the profile owner.
You mean the person who clicked through the ToS that grant Facebook a perpetual, commercial, sublicenceable, license to use the photos however they wish? Including (as they've done in the last) licensing them to third parties to use in adverts?
For me, the quality of ads (meaning the probability that I'd actually click on them) went down a lot when Google started targeting ads at me, rather than at the content of the page that I was viewing. You don't need all of the stalker-like behaviour on ad networks to classify web pages, match them with relevant adverts, and show non-tracking ads.
I'm a bit surprised that there isn't a startup doing tracking-free ads. I bet a lot of people who use AdBlock would be willing to put in an exemption for a company that did not track and ran plain text only ads (you know, like the ads Google used to run, back when we all liked the relevant and non-annoying Google ads).
Apple got a lot of bad press a few years ago for massively overestimating their battery life and is now quite a bit more conservative. They've gone from claiming 6 hours to claiming 8, but at the same time they've shipped lower power CPUs and doubled the size of the battery. There was a Kickstarter for an open source compatible laptop with very similar specs to the MBP floating around last week: they were also claiming 8 hours on battery, but they were shipping a battery half the size of the MBP. I guess they think Linux users keep the screen turned off.
Adjusting the brightness has a big impact on battery life for the MBP. Cutting it to 50% can give you another hour or two. I have gfxCardStatus installed and so disable the nVidia card if I'm going to be using it on battery for a while.
