I have an application written in C++ using Qt4.4.3 on Linux. Doing some benchmarking, I create a large number of rectangles and compare the difference of performance of drawing various line styles. The worst performance is the “dotted” line style, the “dashed” line style is much faster. It would seem to me that these should not vary so...
I've written code for an Epson SED1335 lcd driver (not the 1355) and I would like the driver to behave as a FB driver. When it's all said and done, how is the driver named in the kernel command line? Is it the same name given to the name field in the device_driver structure? Ex. the 1355 driver populates this field with "epson1355fb"...

I want to version control my web server as described here, by creating a git repo out of my /var/www directory. My hope was that I would then be able to push web content from our dev server to github, pull it to our production server, and spend the rest of the day at the pool. Apparently a kink in my plan is that Git won't respect fi...

On Windows if there is no symbols for a module involved in a callstack, say of a crash dump, then all the call below that module in the callstack would be wrong (not only the names are missed, but also the sequence). On Linux or Mac OS X, if symbols are absent, the function names are not shown, but the call sequence are still remain. W...
I got into a discussion a while back. The company I work at develop under Linux and does so in ANSI C. A lot of benefits could come from moving to C++ as far as design goes I think. Our existing code would just have to get rid of all implicit type casts since C++ is a bit stricter about that and it would compile and run as usual. But I w...
