Manually raising (throwing) an exception in Python
...t For me the role of assertions isn't error-checking per se (which is what testing is for), but they set up fences within the code that certain bugs can't get through. So it becomes easier to track down and isolate the bugs, which will inevitably occur. This is just good habits that take little effo...
Can I combine :nth-child() or :nth-of-type() with an arbitrary selector?
...ponding CSS:

...
}
If you're using automated testing tools such as Selenium or processing HTML with tools like lxml, many of these tools allow XPath as an alternative:
//table[contains(concat(' ', @class, ' '), ' myClass ')]//tr[contains(concat(' ', @class, ' '), ' row ...
How do I make my GUI behave well when Windows font scaling is greater than 100%
...ll, or at all, at high DPI. If you plan to turn on TForm.Scaled be sure to test at 96, 125, and 150 DPI for every single form in your project, and every single third party and built in control that you use.
Delphi itself is written in Delphi. It has the High DPI awareness flag turned on, for most ...

Verify your changes with automated tools.
If you have automated tests, run those. If you have a lint, run that. If it's a buildable project, then build it before you commit, etc. In all cases, you need to do a bit of testing to make sure your changes didn't break anything. (Heck, even a m...
Why not use exceptions as regular flow of control?
...y have arbritrary nesting so break's are out as also any kind of condition tests. The if-else pattern is brittle. If I edit out an else or mess up the syntax in some other way, then there is a hairy bug.
Using throw new Success() linearizes the code flow. I use locally defined Success classes -- ch...
What is the recommended approach towards multi-tenant databases in MongoDB?
...nd resources to deal with the complexity of the
design, implementation and testing of this scenario.
If you are not going to have much differences in structure and

Your application design will allow tenants to make only minimal

Why '&&' and not '&'?
...ring value;
if(dict.TryGetValue(key, out value) && value.Contains("test"))
{
// Do Something
}
TryGetValue returns false if the supplied key is not found in the dictionary. Because of the short-circuiting nature of &&, value.Contains("test") is only executed, when TryGetValue r...
Split List into Sublists with LINQ

To overcome this we can try Cameron's approach, which passes the above test in flying colors as it only walks the enumeration once.
Trouble is that it has a different flaw, it materializes every item in each chunk, the trouble with that approach is that you run high on memory.
To illustrate ...
Why can't we have static method in a (non-static) inner class?
...tic inner class.
For an outer class Outer, you can access a static method test() like this:
Outer.test();
For a static inner class Inner, you can access its static method innerTest() like this:
Outer.Inner.innerTest();
However, if Inner is not static, there is now no purely static way to refe...

...json.loads('[' * 991 + ']' * 991)). It crashes at 992. So at least in this test, Mark's can go deeper, contrary to what you said.
