What’s the difference between ScalaTest and Scala Specs unit test frameworks?
Both are BDD (Behavior Driven Development) capable unit test frameworks for Scala written in Scala. And Specs is built upon may also involve the ScalaTest framework. But what does Specs offer ScalaTest doesn't? What are the differences?

base64 encoded images in email signatures
... I believe your question is how to properly insert such an image tag.
You can use an online tool or a few lines of code to generate the base 64 string.
The syntax to source the image from inline data is:
<img src="data:image/png;base64,iVBORw0KGgoAAAANSUhEUgAAAAUA

Why do I need 'b' to encode a string with Base64?
...te data and encodes it uses only the characters A-Z, a-z, 0-9, +, /* so it can be transmitted over channels that do not preserve all 8-bits of data, such as email.
Hence, it wants a string of 8-bit bytes. You create those in Python 3 with the b'' syntax.
If you remove the b, it becomes a string. A...
Generic method multiple (OR) type constraint
...
That is not possible. You can, however, define overloads for specific types:
public void test(string a, string arg);
public void test(string a, Exception arg);
If those are part of a generic class, they will be preferred over the generic version o...
Which iomanip manipulators are 'sticky'?
... Exactly! and the only reason that setw appears to behave differently is because there are requirements on formatted output operations to explicitly .width(0) the output stream.
The following is the discussion that lead to the above conclusion:
Looking at the code the following manipulators ret...
Why C# fails to compare two object types with each other but VB doesn't?
...hose are distinct references.
EDIT: With types which overload the ==, you can get different behaviour - but that's based on the compile-time type of the expressions. For example, string provides ==(string, string):
string x = new string("foo".ToCharArray());
string y = new string("foo".ToCharArray...

I get pretty consistent results with 1M numbers across a dozen attempts:

Trusting all certificates using HttpClient over HTTPS
...ade some headway, but I've run into new issues. As with my last problem, I can't seem to find an example anywhere that works for me.
