I think a case can be made that BerBible-Linux is not a high priority.
Nope, not a priority for me. I do have some experience with wxWidgets. I don't know what other C++ tools,IDEs, etc. are available in Linux. In any case, I consider Linux to be harder to use than windows and not for the BerBible target audience of inexperienced comuter users. That is just my opinion.
My thinking is that if BerBible-Win-Desktop (BerBible.exe) works ok with the WINE (windows emulator), then there is no/nada/zilch need to develop a specific version for Linux. It's done.
Intel has a free "partner" program you can sign up for. One of the benefits is that you can reserve a remote SDV (software development vehicle) and do free testing on it. There is a long list of different machine and o/s combinations ... dual-core (800 and 900 series with two cores that ran hot, also 500 and 600 series with hyperthreading), core-2-duo (2 cores that run cooler than the dual-cores), quad-core, dual quad-xeon, Linux, WinXp, Vista, Server-2003, Longhorn, etc.
http://www.intel.com/partnerI've found the Intel techs to be VERY helpful. Generally, you have use of the SDV for a week at a time. The default setup seems to include Intel development tools (including compilers, profilers, v-tune, thread-analysis, and generally VS2005. I mentioned to a tech that I was interested in "eventually" running tests on a dual-quad-xeon, an entry level core-2-duo, and an older hyperthreading cpu. I have a quad-core q6600, so I can do that testing on my local computer. Anyway, a day or so later he emailed me that the SDV's were ready, so I spent (too much?) time working (playing?) with them during the summer of 2007.
There is a "learning curve" to getting the sdv's set up and useful ... at least there was for this "Microsoft Remote Desktop Connection" newbie.
In my case with a cable modem with asymetrical upload/download speed (download is relatively FAST, so-so upload speed), it is sluggish and "tempermental" to use for uploading test code, data, and executables. It kind of works like the old Norton PC-AnyWhere. I used SDV's quite a bit last summer for multi-core "proof of concept" testing before the Q6600 became affordable.
