git merge - Reverting a git pull that's already been pushed -

-
i'm not sure if duplicate or not it's kind of 1 off scenario: i have "beta" branch, , started new "refactor" branch. i did bunch of code in "refactor" branch. i pulled latest changes beta refactor ( git checkout refactor && git pull origin beta ) my changes ready, checked out beta, , pulled changes refactor beta. ( git checkout beta && git pull origin refactor ) realized beta branch wasn't date, had git pull pull latest beta. now beta branch date, did git pull origin refactor ensure latest there (got auto-commit message refactor being merged beta). i pushed code :( so i'm realizing 2 things did wrong: in step 3, should have done git pull first had latest changesets in beta in step 3 also, realized should have called git merge refactor instead of git pull origin refactor (don't ask me why did this, it's monday , wanted awesome refactor code beta start testing). realize if had done both of th...

qt - How to store a QRect in Sqlite? -

i need store qrect in sqlite database. (i've searched around did not see on this) does qt/qsqlite automatically convert qrect qvariant , handle whatever decomposition needed or have myself , store origin , size values in 4 separate fields? if so, , generalize other qt data types, possible store qvector, qlist? define these (and qrect, etc.) blob types in table definitions? sqlite relational database , things cannot store c++ objects directly. actually c++ object model doesn't allow transparent persistence can try close using specialized tools or libraries. important point objects must designed support persistence. if don't need transparent persistence explicit store/retrieval of objects can pick serialization method (e.g. using single string, or using separate fields attributes). each method has pros , cons depending on want database (e.g. kind of searches or updates want do). something unfortunate c++ metaprogramming abilities poor (just little bett...

java - Compilation error, list not recognised -

i using trove collections, , more specifically, primitive arraylist ints. the declaration of list follows: tintarraylist list= new tintarraylist(); however, facing compilation error cannot explain. when declare list follows: import gnu.trove.list.array.tintarraylist; public class main { tintarraylist list= new tintarraylist(); } , code runs correctly expected. however, when declare list (with different import statement) follows: import gnu.trove.*; public class main { tintarraylist list= new tintarraylist(); } , compilation error appears not recognising tintarraylist. i wondering why error appears? thought using * list should recognized. error doesn't appear when java.util.*; used instead of java.util.arraylist; . the difference * not import sub-levels, in current level. if used import gnu.trove.list.array.* , work expect. the reason works on java.util.* because arraylist class in same folder wildcard.

this code return index of numbers , and non-alphanumeric characters. however, return index first white space not of others , i'm not sure why. shoestring = "fwefw1234132 lkjaldskf98:[]['asd fads fadsf" n in shoestring: if n.isalpha(): continue else: print n, shoestring.index(n) each time, you're calling shoestring.index(n) . n ' ' character. has no way of knowing whether want first space, or second, or 43rd, returns first space. the right way keep track of index, instead of searching find it.* enumerate function makes easy: for i, n in enumerate(shoestring): if n.isalpha(): continue else: print n, as side note, can make code lot simpler reversing if , don't need continue : for i, n in enumerate(shoestring): if not n.isalpha(): print n, you can have more fun using filter function or comprehension: nonalphas = ((n, i) i, n in enumerate(shoestring) if not n.isalp...
