flops - Is there any difference in execution times between two different processors with same amount of gigaflops? -


i have hardware related question debated friend.

consider 2 processors 2 different manufacturers same amount of gigaflops put same computers (i.e. ram , such same both computers).

now given simple program there difference in execution times between 2 computers same processors. i.e. 2 computers handle code differently (for-loops, while-loops, if-statements , such)?

and if, difference noticably or can 1 computers approximately perform same?

short answer: yes, different, possibly so.

flops floating point operations, very crude measure of cpu performance. in general decent proxy performance scientific computations of kinds, not general performance.

there cpus strong in flops - alpha historical example - have more moderate performance in integer computations. means alpha , x86 cpu similar flops have different mips-performance.

the truth is hard make generic benchmark, though many have tried.

Why does Ruby on Rails generate add a blank line to the end of a file? -

running rails generate controller foo home results in: class foocontroller < application controller def home end end (there's nothing on line in actual file, blank line) is there purpose blank line? it's common use newline indicate end of line, last line. many editors (like vi, use) add in newline silently. consensus text files (especially in unix world) should end in newline, , there have been problems historically if wasn't present. why should text files end newline? the tool used count lines in file "wc" counts newlines in file, without trailing newline show 3 instead of 4. it improves readability of templates used in generator. consider: https://github.com/rails/rails/blob/master/railties/lib/rails/generators/rails/controller/templates/controller.rb to remove trailing newline, template have last line of: end<% end -%> instead of: end <% end -%> that seems less readable me. the discussion below refers

keyboard - Smiles and long press feature in Android -

i've created android keyboard. how add features inserting smilies, , using long keypresses display symbols? to create long-press behavior allows select several options pop-up menu, follow guide (specifically pop-up menu section): http://developer.android.com/guide/topics/ui/menus.html smileys (also known emoticons) combination of keys, understood programs , parsed same way. have do, when clicks smiley face on keyboard, simulate pressing of key combination matching emoticon. example, when clicks smiley, should simulate key presses ':' , ')' :). here's list of emoticons: http://en.wikipedia.org/wiki/list_of_emoticons
