The Road to KDE 4: Solid Brings Hardware Configuration and Control to KDE

Filed under

One of the many new technologies for KDE 4 is the often mentioned, but seldom explained Solid Hardware API. Hardware has always been a bit of an annoying element of using Linux and other Unix [like] operating systems, but Solid hopes to fix that for KDE 4. In many ways, Solid is like Phonon, in that it's a Qt/KDE style API around already existing components at the lower level, such as's HAL. It is already quite functional in the backend, and it's already affecting visible KDE components. Read on for more...

Solid is an API for accessing device information such as available disks or networks. It does not deal with device drivers, leaving that to the OS. It does not deal with low level device information, leaving that to already existing, and very good tools such as HAL or other underlying subsystems.

Solid was introduced to the KDE world at large at aKademy, and the first signs of work were the appearance of its website. Since then it has mostly flown under the radar, with the odd mention here and there thanks to Danny Allen's Commit Digests, or the occasional blog posting on the planet. If you visit the #solid channel at (freenode), you'll find that it's sparsely populated, and mostly quiet. But appearances can be deceiving...

Distributing encryption software may break the law

Developers, distributors, and users of Free and Open Source Software (FOSS) often face a host of legal issues which they need to keep in mind. Although areas of law such as copyright, trademark, and patents are frequently discussed, these are not the only legal concerns for FOSS. One area that often escapes notice is export controls. It may come as a surprise that sharing software that performs or uses cryptographic functions on a public website could be a violation of U.S. export control law. Export controls is a term for the various legal rules which together have the effect of placing restrictions, conditions, or even wholesale prohibitions on certain types of export as a means to promote national security interests and foreign policy objectives. Export control has a long history in the United States that goes back to the Revolutionary War with an embargo of trade with Great Britain by the First Continental Congress. The modern United States export control regime includes the Department of State's regulations covering export of munitions, the Treasury Department's enforcement of United States' foreign embargoes and sanctions regimes, and the Department of Commerce's regulations applying to exports of "dual-use" items, i.e. items which have civil applications as well as terrorism, military, or weapons of mass destruction-related applications.
