Evaluating the harm from closed source

Filed under
OSS

Some people are obsessive about never using closed-source software under any circumstances. Some other people think that because I’m the person who wrote the foundational theory of open source I ought to be one of those obsessives myself, and become puzzled and hostile when I demur that I’m not a fanatic. Sometimes such people will continue by trying to trap me in nutty false dichotomies (like this guy) and become confused when I refuse to play.

A common failure mode in human reasoning is to become too attached to theory, to the point where we begin ignoring the reality it was intended to describe. The way this manifests in ethical and moral reasoning is that we tend to forget why we make rules – to avoid harmful consequences. Instead, we tend to become fixated on the rules and the language of the rules, and end up fulfilling Santayana’s definition of a fanatic: one who redoubles his efforts after he has forgotten his aim.

When asking the question “When is it wrong (or right) to use closed-source software?”, we should treat it the same way we treat every other ethical question. First, by being very clear about what harmful consequences we wish to avoid; second, by reasoning from the avoidance of harm to a rule that is minimal and restricts peoples’ choices as little as possible.

Run Linux on Android – part 2

If you want to make full use of Linux on your Android device, the best solutions require rooting it and unlocking its bootloader (see ‘Rooting questions’ section below). Whichever way you do it, this a major step as it will void your warranty and also runs a risk of ‘soft-bricking’ the device – although it can be made to work again if that happens. Another drawback is that unlocking the bootloader will factory-reset your phone and erase all its apps and data, so ensure that you make a backup beforehand. Read more

Is The Open-Source NVIDIA Driver Fast Enough For Steam On Linux Gaming?

While I generally don't recommend Nouveau for Linux gaming systems due to the re-clocking still being a huge work-in-progress to allow the graphics cards to effectively operate at their designated clock frequencies / performance states, I decided to run some fresh tests using the Linux 3.18 kernel and Mesa 10.4-devel to see where things stand today. For the tested Kepler graphics cards that support re-clocking, I tested them at their maximum obtained re-clocked frequencies where the system was stable -- generally still below their rated core/memory frequencies.
