Living on the "Trailing Edge" of computer development sometimes makes a LOT of sense.

1. Kdevelop 3 vs. 4.

The kde4 version of this ide/programming editor became a bit too ambitious, I think. Spitting out one perfect plasma widgets at the click of a button. But it's unrealistic to think that an automatic plasmoid creator will lead to programming prowess and many of the old features that were in kdevelop3 are sorely missed.

I'd take the graphical...

Last week, I semi retired my N900 replacing it with a Samsung Galaxy SII. Initial impressions are that the SGS2 is very nice and all but it doesn't have the same 'feel' as the Nokia. My N900 is without doubt a small computer with phone functionality. The SGSII is a smartphone. There is a subtle but distinct difference.

So, the N900 will live on at home with the sim removed but connected to my wireless network. I see it fulfilling various roles, one of which will be as a device...

[Recommended: Kate (Advanced Text Editor).]

In my setup I have HOME/bin with a subdirectory named src where I put my private stockpile of micro-programs and where I can uninstall them easily by simply deleting the files or the directories containing them.

Under HOME/bin/src I have the directories named for the apps they contain, in some cases being collections of apps with additional subdirectories.

In order to put the apps in the path all that is necessary...

Setting watchpoint for watching writes on a variable in C++ - GDB

Watchpoint basics:
  • Watchpoints are set on the variables, not on the functions or on the lines of code.
  • When the watched variables are read or written, the watchpoint gets triggered and the program's execution stops.

Watchpoints on non-global variables:
  • To set a watchpoint on a non-global variable, we must first set a breakpoint that will stop the program in the scope of the variable to be watched.
  • The watchpoint can be set after the program stops at the above set breakpoint.

See source code intermixed with assembly

Posted 01-16-2012 at 04:25 AM by hydraMax (Bits and Pixels)

Maybe everybody else already knows this, but I thought it was pretty neat anyway:

If you compile some C code with -g option (to include debugging symbols), you can then use objdump on the binary, with the -S switch, to get source code intermixed with assembly. For example, here is a snippet from one of my binaries:

int main() {
  401163:       55                      push   %rbp
  401164:       48 89 e5                mov    %rsp,%rbp
