问题 I want to push several single commits to a git remote repo. I followed Geoff's answer found here to do so: How can I pushing specific commit to a remote, and not the previous commits? The commits I want to push are not at the head, so I have to reorder the commits using rebase first and I used these instructions to do so: http://gitready.com/advanced/2009/03/20/reorder-commits-with-rebase.html Essentially I've done: git clone git commit git commit ... git pull git rebase -i HEAD~3 git push

问题 I need some help to filter a dataframe. The df has several columns and I want to split it into two dataframes: 1- One including only the rows in which the first column is a duplicate (including all of the replicas). 2- The rest of the rows, which are not duplicates. Here is an example: This would be the original. V1 V2 [1,] "A" "1" [2,] "B" "1" [3,] "A" "1" [4,] "C" "2" [5,] "D" "3" [6,] "D" "4" I want to turn into this: V1 V2 [1,] "A" "1" [2,] "A" "1" [3,] "D" "3" [4,] "D" "4" And this: V1

问题 I can find lots of information about merging two DataTables and dropping duplicate rows, but I need the opposite. I need to know if anyone has an easy way to merge two DataTables where the result of the merge is a DataTable with only rows that exist in both tables. 回答1: Like this: var intersection = table1.AsEnumerable() .Intersect(table2.AsEnumerable(), DataRowComparer.Default); DataRowComparer compares rows by their column values. 来源： https://stackoverflow.com/questions/6833454/c-sharp

问题 Does anyone have an elegant sql statement to delete duplicate records from a table, but only if there are more than x number of duplicates? So it allows up to 2 or 3 duplicates, but that's it? Currently I have a select statement that does the following: delete table from table t left outer join ( select max(id) as rowid, dupcol1, dupcol2 from table group by dupcol1, dupcol2 ) as keeprows on t.id=keeprows.rowid where keeprows.rowid is null This works great. But now what I'd like to do is only

问题 I have two different layouts for two different Activities. There is a button in each of these layouts with the same id: "@+id/btnOK". When I set a property for one of these buttons programmatically, I get a NullPointerException . But when I change one of ids, everything is okay. Is it really true that we cannot have duplicate IDs in different layouts in android? 回答1: On the "Duplicate Ids in layouts" topic, extracted from android developers Defining IDs for view objects is important when

问题 I have the following setup: public class A { private Set<C> cSet; } public class B { private Set<C> cSet; } public class C {} A's and B's cSet might have references to same C instances. I want to serialize A and B such that upon deserialization I don't have duplicate C objects. Will Java know how to do the right thing if I serialize/deserialize it into the same ObjectOutputStream, or might I end up with more C instances than I started out with? 回答1: No, you won't get more instances of C than
