Hi, I'm a bit curious - why do you consider changing from WMV to Flash important for Linux or Firefox users? Last time I checked, most Linux distributions could play neither WMV nor Flash movies out of the box, but software to do both is available for free. Software to play WMV is even available as free software (e.g., mplayer)? Or am I missing something? True, but... 1. Adobe has released a full spec for their flash format allowing a complete Free implementation. They also released the scripting engine as open source. 2. Adobe provides a proprietary flash player for Linux. 3. WMV (really the associated codecs, but the affect is the same ) is covered by numerous patents which are activly protected in the most brutal way, whereas the FLV format, as so much that it is patented (I don't know it is but I assume it is) is not, at the moment. Not a case of black and white by a long shot, but I would say flash is brighter then WMV. Gilad -- Gilad Ben-Yossef Chief Coffee Drinker Codefidence Ltd.

[Telux] Next OSDClub Tel Aviv Meeting: Puppet on 7-September
Hi all! The Tel Aviv OSDClub (Open Source Developers Club - a merger of the Tel Aviv Linux club and Perl-Israel meetings), will hold the following meeting: http://wiki.osdc.org.il/index.php/Tel_Aviv_Meeting_on_07_September_2008 - Puppet - a tool for central management of many computers. The Tel Aviv Linux Club (also now known as OSDClub Tel Aviv - Open Source Developers' Club) will hold a presentation by Ohad Levy on Sunday, 07-September-2008 about Puppet - the Central Management Tool. The meeting will take place at Tel Aviv University, at the Schreiber MathsCS building, room 008 on 18:30. So mark your calendars.

This makes /proc/PID/mem somewhat redundant to using PTRACE_PEEKDATA. For some reason, even as a debugger, you cannot mmap it and use it as a forced shared mem mechanism. Furthermore, I have actually had cases where PTRACE_PEEKDATA returned data and /proc/PID/mem didn't for the same memory area, even when attached as a debugger. As such, I rate /proc/PID/mem as somewhere beneath useless. What Noam is looking for, as far as I can tell, is something where pause the program and tell the debugger now the value I'm looking for is 5, resume the program, play some more, and then pause it and say now the value is 4. Eventually, hopefully, you narrow down the value to the point where you know where it is stored in memory, despite not having any prior knowledge about the program. This is not difficult to write (for some definition of difficult).
