Comment: My extremely similar tool: dynpk (Score 2, Interesting) 385

I very recently published a tool that performs a similar task. dynpk (my tool) bundles programs up with packages from your system, then wraps them with some other stuff to create a bundle that essentially allows you to run a Fedora program on a RHEL machine (and probably Ubuntu or Debian, but this is outside my needs...).

Recompiling loads of libs for RHEL isn't fun or particularly maintainable. Therefore, use the ones from Fedora!

Google Pulls Open Source CoreAVC Project Over DMCA Complaint 207

from the not-like-google-has-much-choice dept.
rippe77 writes "Google has taken down the open-source project CoreAVC for Linux due to a DMCA complaint. The CoreAVC codec is a commercial high-definition H.264 DirectShow filter for windows provided by CoreCodec Inc.. The CoreAVC for Linux project provided various patches for Linux applications (mplayer, MythTV, xine) to use these DirectShow decoder filters in Linux. The takedown is quite controversial, as the CoreAVC project did not provide any copyrighted material — only the means to use the DirectShow filters in Linux." (The takedown notice is not yet up at Chilling Effects, but Google's page has a link that will take you there when it is.)

IBM Heralds 3-D Chip Breakthrough 99

David Kesmodel from WSJ writes to let us know about an IBM breakthrough: a practical three-dimensional semiconductor chip that can be stacked on top of another electronic device in a vertical configuration. Chip makers have worked for years to develop ways to connect one type of chip to another vertically to reduce size and power use. The IBM technique of "through-silicon vias" offers a thousand-fold reduction in connector length and a hundred-fold increase in connector density. The new chips may appear in cellphones and other communication devices as soon as next year. PhysOrg has more details.

Electrically Conductive Cement 159

zero_offset writes "The Tokyo Institute of Technology has announced a process for creating an inexpensive, nearly transparent, electrically conductive alumina cement. The conductivity is comparable to metal, and the transparency should be adequate for use in display panels. The process relies upon commonplace and inexpensive metals compared to the rare metals such as iridium currently used in display panels."

Comment: PWM and some interesting stuff... (Score 1) 453

The best way of controlling an LED's brightness is though using PWM, and that's a fact. The only thing is how to control the PWM, there are two basic possibilities. The first is to bung in a micro(processor|controller) and multiplex the LEDS in a nice fashion connected to that. The second method, would involve building some (quite simple if you think about it) logic circuitry that controls the PWM from a serial input. The serial input could come from something like your serial port, taken through a MAX233 or MAX232 to get the voltage levels down.

I think that the processor method is much better, because all you have to do is put some sort of connector on the main board that allows you to add and change the method of control - e.g. serial, parallel or some sort of wireless (which would infact be serial...) thing.

You could also connect an ethernet device to the bus so that you could control it via ethernet.
