Wndchrm - an open source utility for biological image analysis

,----[ Quote ]
| Methods: Wndchrm is an open source utility for biological image analysis.
| The software works by first extracting image content descriptors from the raw
| image, image transforms, and compound image transforms. Then, the most
| informative features are selected, and the images are analyzed.


All research projects that are funded by governments should be free software.

| The software package contains a sample implementation for Linux systems which
| consists of the stacks for the Managing Node (master) and for the Controlled
| Nodes (clients). The Open Source implementation reaches cycle times up to 0.5
| milliseconds while ensuring high synchronicity.



Open-source hardware: Open sesame

| Now the same approach is being applied to hardware, albeit in a modified
| form. The open-source model cannot be directly carried over to hardware,
| because software can be duplicated and distributed at almost no cost, whereas
| physical objects cannot. Modifying source code and then distributing a new,
| improved version of a program is much easier than improving and sharing the
| design of, say, an open-source motorbike. Some day, perhaps, fabricating
| machines will be able to transform digital specifications (software) into
| physical objects (hardware), which will no doubt lead to a vibrant trade in
| specifications, some of which will be paid for, and some of which will be
| open-source.

| But until that day, the term “open-source hardware” is being used in a
| narrower sense. It refers to an emerging class of electronic devices, for
| which the specifications have been made public, so that enthusiasts can
| suggest refinements, write and share software improvements, and even build
| their own devices from scratch. This is not as daft as it sounds. Even if all
| the details needed to build something are available, few people will have the
| tools or the inclination to do so.
| [...]
| Some enthusiasts point to 2005 as a crucial year: that was when work began on
| devices such as the RepRap (a rapid-prototyping machine that will, its makers
| hope, be able to replicate itself) and the TuxPhone, an open, Linux-powered
| mobile-phone. It was also when Sun Microsystems, a computer-maker, decided to
| publish the specifications of one of its microprocessors, the UltraSPARC T1.
| The open-source hardware trend is now growing fast, says Adrian Bowyer, a
| mechanical engineer at the University of Bath and the inventor of the RepRap.
