...ies a proper (unsigned annotated) tag (option '-a'), and not a lightweight one. So you are good with your initial command. This differs from: git show-ref --tags -d Which lists tags with their commits (see "Git Tag list, display commit sha1 hashes"). Note the -d in order to dereference the ann...

... Oddly, no one has suggested something like this: index = Something.find(array_of_ids).group_by(&:id) array_of_ids.map { |i| index[i].first } As efficient as it gets besides letting SQL backend do it. Edit: To improve on my own ...

... @Ismael Miguel too much code? Just because you put all those functions on one line doesn't mean you're using less code. It might look more compact but it comes at the expense of readability. – Jage Mar 5 '15 at 21:44 ...

...ed) and 5 is the length If the underscores around the digits are the only ones in the input, you can strip off the prefix and suffix (respectively) in two steps: tmp=${a#*_} # remove prefix ending in "_" b=${tmp%_*} # remove suffix starting with "_" If there are other underscores, it's proba...

... need to multiply them and then print the results of each cell. As soon as one cell is ready I need to print it, but for example I need to print the [0][0] cell before cell [2][0] even if the result of [2][0] is ready first. So I need to print it by order. So my idea is to make the printer thread wa...

... I do it mostly like the one above, but for accessibility reasons, I need to support the possibility of images being disabled in the browser. So, rather than indent the text from the link off the page, I cover it by absolutely positioning the <spa...

...2-bit x86. x86-64's increase from 8 to 16 integer and vector registers is one of the biggest factors in 64bit code being faster than 32-bit (along with the more efficient register-call ABI), not the increased width of each register. A further increase from 16 to 32 integer registers would help som...
