Map a network drive to be used by a service
...per service will need to pass on all appropriate SCM commands (start/stop, etc.) to the real service. If the real service accepts custom SCM commands, remember to pass those on as well (I don't expect a service that considers UNC paths exotic to use such commands, though...)
Things may get a bit tri...
In Python, what happens when you import inside of a function? [duplicate]
... "appropriate scope" be module-level means each use of goo.this, goo.that, etc, is two dict lookups -- one for goo and one for the attribute name. Having it be "function level" pays one extra local-variable setting per run of the function (even faster than the dictionary lookup part!) but saves one...
It is more efficient to use if-return-return or if-else-return?
...sing a switch construct or for Python, enumerating a dict/using a callable/etc.). Therefore almost all if-else-return are cases of guard clauses and those are always testable (mock the tested expression) without the else.

Assign same value to multiple variables at once?

That means
$c = 1234;
$a = $b = $c;
$c = 5678;
//$a and $b = 1234; $c = 5678;
$c = new Object();
$c->property = 1234;
$a = $b = $c;
$c->property = 5678;
// $a,b,c-&g...
Rails Model, View, Controller, and Helper: what goes where?
...king out whether they are logged in, whether they should see certain data, etc. In the end, the controller looks at requests and works out what data (Models) to show and what Views to render. If you are in doubt about whether code should go in the controller, then it probably shouldn't. Keep your co...
Why should I use IHttpActionResult instead of HttpResponseMessage?
...ide those convenient helper methods of ApiController such as Ok, NotFound, etc.
Basically, I think a class implementing IHttpActionResult as a factory of HttpResponseMessage. With that mind set, it now becomes an object that need to be returned and a factory that produces it. In general programming...
presentViewController:animated:YES view will not appear until user taps again
... subtle bug, because if you have the slightest feedback animation, timers, etc. in your code this issue won't surface because the runloop will be kept alive by these sources.
