How to format an inline code in Confluence?
...
A reliable way to make this work is to type in {{foo}}; it always recognises 'foo' as needing preformatting, then paste whatever you really wanted to put in there between the 'f' and the 'o', then remove the 'foo' text. You should be left with what you really wanted, prefor...
Using XPATH to search text containing
...st case. For example, you
may need to type text in a field like
this: "foo ". But if you simply
write <td>foo </td> in your
Selenese test case, we'll replace your
extra spaces with just one space.
This problem has a simple workaround.
We've defined a variable in Sele...
Different ways of loading a file as an InputStream
...s the answers in this question, suggest that loading absolute URLs, like "/foo/bar.properties" treated the same by class.getResourceAsStream(String) and class.getClassLoader().getResourceAsStream(String). This is NOT the case, at least not in my Tomcat configuration/version (currently 7.0.40).

Insert picture/table in R Markdown [closed]
.... "Resizing images" can be done directly. For example:

The dimensions can be provided with no units (pixels assumed), or with "px, cm, mm, in, i...
Creating an R dataframe row-by-row
...then during your operations insert row at a time
DF[i, ] <- list(1.4, "foo")
That should work for arbitrary data.frame and be much more efficient. If you overshot N you can always shrink empty rows out at the end.

Using emit vs calling a signal as if it's a regular function in Qt
...ou can look at by inspecting the C++ code generated by moc.
For example a foo signal with no parameters generates this member function:
void W::foo()
{
QMetaObject::activate(this, &staticMetaObject, 0, 0);
}
And the code emit foo(); is pre-processed to simply foo();
emit is defined in Q...
It is more efficient to use if-return-return or if-else-return?
...
From Chromium's style guide:
Don't use else after return:
# Bad

# Good
if (foo)
return 1
return 2
return 1 if foo else 2

How to put multiple statements in one line?
...of simple statements, separated by semi-colon:
for i in range(10): print "foo"; print "bar"
But as soon as you add a construct that introduces an indented block (like if), you need the line break. Also,
for i in range(10): print "i equals 9" if i==9 else None
is legal and might approximate wha...
