• Is it possible for computers to tell time without a built in clock?

  - by CrazyJugglerDrummer

  Computers keep time normally with a built in clock on the motherboard. But out of curiosity, can a computer tell time without this? I would think not as a computer can only execute instructions. Of course, you could rely on the computer knowing its own processing speed, but that would be an extremely crude hack that would take up way too many clock cycles and be error prone.

• Is there an HTML attribute to tell smartphone keyboards to show special email keys?

  - by slolife

  I notice that when using my touch-screen smartphone (no physical keyboard) that when an app asks for an email address to be entered in a textbox, the on screen keyboard is modified slightly to provide specialized keys that enter blocks of text, like '.com' or push some characters to the foreground key, like '@'. Is there an HTML attribute or style that I can add to my HTML input boxes that will tell the smartphone/browser to provide these specialized keys?

• How can you tell if a person is a programmer?

  - by Lucas Jones

  I was wondering when I read the famous "Programmer Habits" thread, I was wondering: Is there any way to tell if somebody is a programmer without actually asking them?

• How can I get valgrind to tell me the address of each non-freed block of memory?

  - by James

  Valgrind tells me function xxx allocated memory which was not freed. Fine. It's proving more difficult than usual to trace however. To this end I have created numerous: #ifdef DEBUG fprintf(stderr, "something happening:%lx\n", (unsigned long)ptr); #endif So I just need to match these ptr addresses that are displayed with the addresses of non-freed memory. How can I get valgrind to tell me the address of each non-freed block of memory?
