Merge two Git repositories without breaking file history
...ries when I do git log , but if I do git log <file> it shows only one commit for that file - the subtree merge. Judging from the comments on the above answer, I'm not alone in seeing this problem but I've found no published solutions for it.

How can I create a Makefile for C projects with SRC, OBJ, and BIN subdirectories?
..., you might consider more sophisticated dependency handling; if you modify one of the header files, this makefile will not know which objects/executables must be rebuilt. But that can wait for another day.
EDIT:
Sorry, I omitted part of the $(OBJECTS) rule above; I've corrected it. (I wish I could ...
How do I count the number of occurrences of a char in a String?
...
My 'idiomatic one-liner' for this is:
int count = StringUtils.countMatches("a.b.c.d", ".");
Why write it yourself when it's already in commons lang?
Spring Framework's oneliner for this is:
int occurance = StringUtils.countOccurrences...
Best practice for instantiating a new Android Fragment
...nk I'm missing something here, couldn't you use a constructor here anyway, one that creates the Bundle and calls setArguments() still since it will only be called by your code (and not when Android re-creates your fragment)?

Creating range in JavaScript - strange syntax
... if you manage to read between the lines (or you can just trust me on this one, but don't), it basically boils down to this:
function Array(len) {
var ret = [];
ret.length = len;
return ret;
}
(operates under the assumption (which is checked in the actual spec) that len is a valid uin...
jQuery callback on image load (even when the image is cached)
...hecking and triggering the event based off .complete, like this:
$("img").one("load", function() {
// do stuff
}).each(function() {
if(this.complete) {
$(this).load(); // For jQuery < 3.0
// $(this).trigger('load'); // For jQuery >= 3.0
}
});
Note the change from .bind()...
Retrieving the last record in each group - MySQL

WHERE m2.id IS NULL;
Regarding performance, one solution or the other can be better, depending on the nature of your data. So you should test both queries and use the one that is better at performance given your database.
For example, I have a copy of the StackOverflo...
How do I trim whitespace from a string?
...
Just one space, or all consecutive spaces? If the second, then strings already have a .strip() method:
>>> ' Hello '.strip()
'Hello'
>>> ' Hello'.strip()
'Hello'
>>> 'Bob has a cat'.strip()
'Bob has a ...
Resolve build errors due to circular dependency amongst classes
...nker errors in a C++ project due to some bad design decisions (made by someone else :) ) which lead to circular dependencies between C++ classes in different header files (can happen also in the same file) . But fortunately(?) this doesn't happen often enough for me to remember the solution to this...
Best practices: throwing exceptions from properties
...ic to decide where to inject exception catch statements.
As a side note, one should be aware that just because a property is not designed to throw an exception, that doesn't mean it won't; it could easily be calling code that does. Even the simple act of allocating a new object (like a string) cou...
