Comment Re:Pull your head out (Score 1) 665

A scientific theory usually have a set of predictions beyond the initial claims that are testable, event if not visible phenomena or directly measured properties. What I described in the example of the Big Bang Theory is precisely testing a scientific theory, as the expected background radiation IS one of the predictions.

If your standard for any scientific theory is based on repeating an experiment or directly visualizing some effect, most of the science of the last 2 hundred centuries is indeed untested, as most of its results are not directly visible, but tested by mesasureable effects. Event relatively simple properties of materials, such as eletronic currents visible, and as such measured through indirect effects, for example, old ammeters using magnetic fields to measure the value of said electronic current, instead of counting the amount of electrons passing per second on a conductor.

In the case of the big bang theory, you have some properties of the universe that are predicted by the theory, such as the presence of the background radiation and the uniformity of mass distribution, among others, that are predicted to exist in a universe where a "big bang" occurs. It is a lot like observations from particle accelerators such as the LHC. There are no means to directly measure a many subatomic particles, but you can measure the particles resulting from the expected decays with some confidence, therefore testing aspects of the theory.

Comment Re:Ball drones (Score 1) 108

Last time I read about this ball drone the estimated battery life was around 15 minutes, making it useful for a very limited range. Also, this ball "drone" is still remote-controlled, putting it definitely outside of the drone category, although similar devices have been adapted to autonomous fly even by hobbyists.

Unless someone can get a power source with better weight/stored energy ratio than the batteries usualy found at these devices, those drones will still be toys. Maybe a buoyant/quadcopter hybrid could overcome this, using far less energy to stay flying and depending on volume, a useful payload capacity.

Submission + - New Linux Radeon Driver Enables Full 2D Acceleration For HD 7000 (phoronix.com)

skade88 writes: From the Phoronix article: 'A commit to the xf86-video-ati driver this morning by AMD's Michel Dänzer says it enables full 2D acceleration for the Radeon HD 7000 "Southern Islands" GPUs.

While the AMD Radeon HD 7000 series graphics cards have been out for one year now, the open-source support has been shoddy. AMD was fairly quick in delivering kernel mode-setting support, but the 3D bring-up has been slow. There were significant architectural changes to the GPU between the HD 6000 and HD 7000 series hardware, which necessitated the introduction of a new Gallium3D driver called RadeonSI, but for end-users simply wanting their hardware to work on open-source software, it's been a damn slow process.'

Also, slax has a "run from memory" mode where the whole distro is loaded to ram, and as such after booting it runs hellish fast. So a computer with 1Gb of ram can still run the whole OS from ram very fast. I already used this mode to boot slax on a whole computer lab/classroom from a single usb drive.

I don't know much about the latest version (7.0), but on previous versions Slax could be reduced to use only the "core" module, which used to be around 50Mb containing only command line tools. It is very handy as a base to build a personalized live cd using slackware packages or a remote boot image.

but the point is, android can ultimately run mozilla os apps too. on the same hw mozilla os runs.

mozilla os isn't even the first html5 ui for mobile attempt nor the first "hey let's do apps in html5 for mobile!" attempt. nokia wasted hundreds of millions on that shit already. mozilla just went because html5 because they build a browser.

I guess you are confusing Nokia with Palm/HP, as WebOS ran on html+js and Meego/Maemo used gtk and latter Qt with 100% native apps

Truth is, as most of the code on android is apache licenced or GPL (as the kernel) there is no need to ask google's permission to make anything with it.

Except for two things, some OEMs get advanced access to the code base before it's released to the general public and some OEMs get special access to the core Android developers if they can't get something to work on their own.

Exactly. Google can't "ban" anyone from using android source code, but they can deny access to their proprietary apps and also from being part of the Nexus product line, which obviously depends on early access to the sources and SDK. Also, it is somewhat clear that access to core android developers during a device development is a valuable asset to any manufacturer, as it is the closest to a community android gets due to the open source/closed development environment strategy used by Google.

The only parts of the operating system that are under a non-permissive licence that can be considered a showstoper would be the "brand" apps, as gmail, youtube and the google play store.
