C++11 std::threads vs posix threads
...is AFAIK a debilitating flaw in the use of std::thread as it bars one from setting up the bona fide multi-threaded signal handling pattern to process all signals in a dedicated thread and block them in the rest. You are forced to assume std::thread is implemented using pthreads and hope for the best...
Disable/turn off inherited CSS3 transitions
... targets the same property as specified in the other transition rules, but sets the transition time to 0, which effectively prevents the transition from being noticeable. The use of the a.noTransition selector is simply to provide a specific selector for the elements without transitions.

How do I escape a single quote in SQL Server?
...r you (like it didn't for one of my recent REPLACE() queries), you can use SET QUOTED_IDENTIFIER OFF before your query, then SET QUOTED_IDENTIFIER ON after your query.
For example
SET QUOTED_IDENTIFIER OFF;
UPDATE TABLE SET NAME = REPLACE(NAME, "'S", "S");

npm windows install globally results in npm ERR! extraneous
...en i did an 'npm ls'. I thought this was some sort of a globally corrupted setup after having lots of tinkering. I learn the following observations here:
'npm ls' gives different outputs depending on what is your current folder location.
'npm ls' tries to detect the presence of a 'node_modules' fo...
List of remotes for a Git repository?
... majority of the answers assume you are querying from within a git working set.
The questioner is assuming you are not.
As a practical example, assume there was a repository foo.git on the server.
Someone in their wisdom decides they need to change it to foo2.git. It would
really be nice to do a li...

Closing JDBC Connections in Pool
...nstructor. Now, this class has a ton of methods, each with conn, stmt and rset as local variables, connections are in a try block, and in finally there is a 1-line call csrClose (conn, stmt, rset), where all 3 are closed (in reverse order). Now, the DTO you develop in the example is a mirror image o...
What's the best way to trim std::string?
...ing it. I Agree. An implementation that I would likely prefer would be two sets of functions, one for in place and one which makes a copy. A better set of examples would be:
#include <algorithm>
#include <functional>
#include <cctype>
#include <locale>
// trim from start (...
What's the difference between RANK() and DENSE_RANK() functions in oracle?
...ases where there is a “tie”; i.e., in cases where multiple values in a set have the same ranking. In such cases, RANK() will assign non-consecutive “ranks” to the values in the set (resulting in gaps between the integer ranking values when there is a tie), whereas DENSE_RANK() will assign co...
